Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eccentric load countermeasure structure for maintaining a table in a horizontal state even when an eccentric load is applied and smoothly moving a heavy object up and down without falling or the like. The present invention relates to a lift table and a self-propelled lift table having a structure capable of resisting an unbalanced load, which is suitable for use in lifting and unloading in a wide range of hoisting and unloading work sites in which scenes in which an unbalanced load is likely to act frequently.

[0002]

2. Description of the Related Art Conventionally, a lift table as shown in FIGS. 17 and 18 has been used in order to speed up and lower loading and unloading operations for repeatedly loading and unloading heavy articles and to reduce the physical burden on workers. a is used.

The lift table a is pressed against one inner arm b1 which is an example of one arm or one outer arm c1 which is an example of one other arm. The operation of the hydraulic cylinder d provided so that the
One inner arm b1 and one outer arm c1 are centered on the rotating shaft member e1, and the other inner arm, which is an example of the other arm, is centered on the connecting / rotating shaft member e2. The opening and closing operation of the arm b2 and the other outer arm b2 which is an example of the other arm (so-called scissor link mechanism m)
Opening / closing operation), and one of the inner arms b1 is provided near one end of the other inner arm b2 and is in contact with the back side end of the table f. The roller h1 and the other roller h2, which is an example of the other roller, are rotated. Then, the table f is moved up and down by the operation of the one roller h1 and the other roller h2, and the lifting / unloading work for lifting / unloading the articles mounted on the table f is performed. It is what you do.

[0004]

In other words, in a daily loading / unloading operation, the center of gravity of the article mounted on the table f should coincide with the center position of the table f. The lift table a is not always used for lifting and unloading work so that the unbalanced load does not act on the table f.
The position of the center of gravity of the article mounted on the table f,
Does not match the center position of the article, the center of gravity of the article is, for example,
A position closer to an edge in a direction perpendicular to the direction in which the one roller h1 and the other roller h2 rotate (hereinafter, referred to as an “eccentric position S”)
And ), The eccentric load having the eccentric position S as an action point causes one of the rollers h1 constituting the scissor link mechanism m.
Act on.

[0005] On the other hand, the lift table a has a high ability to lift heavy articles in comparison with its own weight being light, and, because of its light weight, can easily be lifted and lowered by appropriate transportation means if necessary. Since the existence value as a lifting and lowering work equipment has been found at a point that can be transported to the loading position, it has not been designed and manufactured on the premise that the above-mentioned eccentric load acts, and does not generate an eccentric load The scissor link mechanism m smoothly opens and closes the article having a predetermined weight mounted on the table f, and has sufficient rigidity to be able to carry the cargo up and down without any trouble. The arm b2, one outer arm c1, the other outer arm c2, the connecting member i, and the like are designed to be provided on respective components of the lift table a.

For this reason, when an unplanned unbalanced load acts on one of the rollers h1 when the heavy article is mounted on the table f, one of the rollers provided with one of the rollers h1 on one end side. Since the inner arm b1 does not have enough rigidity to receive a force which is not assumed in the design, the other inner arm b2 is connected to the inner arm b1.
The one inner arm b1 is pushed further open about the connecting / rotating shaft member e1 even more than being pushed open about the rotating shaft member e2.

[0007] By such an operation, the one inner arm b1
One of the rollers h1 supporting the table f and the mounted heavy article from one side is provided on the other inner arm b.
2, the table f and the other roller h2 supporting the mounted heavy article from the other side are further extended toward the front side of the lift table a (the direction of the arrow A shown in FIG. 17). Rotate for time. As a result, there is a difference in the rotational movement distance between one roller h1 and the other roller h2. As a result, the table f cannot be maintained in a horizontal state and is inclined, so that the table f is mounted. The danger of heavy articles falling is increased.

In order to avoid such a state, the thickness of the material used for each component of the lift table a such as the scissor link mechanism m is increased to increase the rigidity, and even if the above-mentioned eccentric load acts as described above, the illustrated example is adopted. Care has been taken to suppress the above-described further push-open movement of one inner arm b1.

However, when such a treatment is performed, the weight of the lift table a becomes excessively large as compared with the lifting capacity of the article, and the lift table as the above-described lifting and lowering work apparatus is used.
The value of Bull a is greatly diminished. In addition, since the situation where an unbalanced load is applied to one of the rollers h1 remains unchanged, the opening and closing structure of the scissor link mechanism m
Since the movement of one side of the scissor link mechanism, which is caused by the action of the eccentric load, to be pushed and opened more than the other side cannot be completely prevented, in consideration of an accidental drop of an article from the table, There is a certain limit to the weight of the articles mounted on the table even if the weight is excessive. Further, when the weight of the lift table is excessively increased, it is very difficult to repeatedly perform the required loading / unloading while repeatedly changing the lifting / lowering position at a wide range of loading / unloading work sites. Will happen.

The present invention has been made in consideration of the above circumstances, and has been described in connection with an operation in which one side of a scissor link mechanism is further pushed and opened from the other side due to an eccentric load acting on a table. Without changing the components of the mechanism, while maintaining the characteristics of the lift table, which is lighter than the lifting capacity, the lift table that can effectively block and counter the uneven load, and the uneven load are often Provided is a lift table having mobility so that the lift table can repeatedly execute smooth lifting / unloading operations within a short period of time in a wide range of loading / unloading work sites having an action scene.

[0025]

According to the first aspect of the present invention, when a cylinder is operated and a piston rod presses a pressing force transmitting member to apply a pressing force, the pressing force is applied to one of the first contacts. -Transmitted to each of the arm and the other arm,
If it is necessary to increase the lifting force and the pressing force transmitting member is constructed so as to extend between one of the other arms and the other of the other arms, one of the other arms is used. And the other arm, the scissor link mechanism is opened up around the connecting / rotating shaft member so as to stand up.

Then, one roller is on the inner side of one upper wide rail member, and the other roller is on the inner side of the other upper wide rail member. The table is simultaneously pivoted to the rear of the table at the same rotational speed.
While one side and the other side of the table are pivotally supported, one upper pinion is engaged with one upper rack in association with the rotation of one roller, and the other pinion is rotated. In conjunction with the rotation of the roller, the other upper pinion meshes with the other upper rack and simultaneously meshes with the other upper rack, respectively, and simultaneously moves rearward of the table. It moves up in a horizontal state.

When the table moves upward to a predetermined article loading position, heavy articles are loaded on the table. At this time, if the center of gravity of the heavy article does not coincide with the center position of the table, the table is moved. -An eccentric load acts on one or the other side of the cable, so that one of the rollers can be applied to one of the arms, or the other of the other The acting force of the eccentric load is transmitted to one arm, and an excessive load is applied to the arm on the other side.

Then, after the arm on the other side is pushed and opened centering on the connecting / rotating shaft member to perform the sitting operation, the closing operation for lowering the table is stopped for a certain period of time. In the same manner, one arm or the other arm is pushed and opened, so as to perform a further sitting operation and to perform a closing operation for further lowering the table. Therefore, a table provided to one upper pinion or the other upper pinion due to a heavy article being loaded on the table with an eccentric load.
The turning force for turning the front of the bull is preserved.

However, even in such a state, while one upper pinion meshes with one upper rack, the other upper pinion meshes with the other upper rack. -Since both ends of the table-side turning power transmission member are firmly supported by the teeth, the above-mentioned preserved turning power is transmitted to the upper pinion on the mating side via the table-side turning power transmission member. .

Then, the upper pinion on the mating side, together with the upper rack meshing with the upper pinion, has an arm re-closing operation guiding action for the arm immediately after stopping the above-described closing operation.
At this time, the arm receives rotational resistance from the arm, and the transmitted rotational power is reduced. Then, the reduced turning power is transmitted to one upper pinion or the other upper pinion in the same manner as described above.

In this way, the rotational force transmitted at the beginning is reduced and the rotational force of the same force is applied to both upper pinions, so that one of the ones that is to rotate further to the front side of the table. Independently of one roller or the other, one upper pinion is in synchronism with the other upper rack, and the other upper pinion is in mesh with the other upper rack. The same time

By the operation of the table-side rotating power reduction transmission / tuning rotation mechanism, the table is slightly lowered from before loading the heavy articles, but the horizontal state is maintained and the heavy articles are moved. Mounted on top. Thereafter, when the cylinder is moved up again, the heavy article is smoothly moved up to the predetermined height without being dropped from the table and is conveyed to the predetermined position.

According to the configuration of the invention of claim (2), in the same manner as in the configuration of the invention of claim (1), after the horizontal state is maintained and the table is moved up to a predetermined position. When a heavy article is loaded on a table in a state in which an eccentric load is generated in the same manner as described above, the table in which the arm of the other party sits down does not fall in the same manner as described above. After stopping the closing operation, one of the
The arm or one of the other arms is pushed and opened about the connecting / rotating shaft member to perform the closing operation for lowering the table further. The turning force applied to one lower pinion or the other lower pinion as a result of heavy articles being loaded onto the table is preserved.

However, even in such a state, one lower pinion meshes with one lower rack, and the other lower pinion meshes with the other lower rack. Since both ends of the table-side turning power transmission member are firmly supported by the teeth, the above-mentioned preserved turning force is transmitted to the lower pinion on the mating side via the base-side turning power transmission member.

Then, the lower pinion of the mating side guides the arm reclosing operation in a state where the lower pinion with the meshing lower rack is stretched on the base against the arm immediately after stopping the above-mentioned closing operation. At this time, since the arm receives a rotational resistance from the arm, the transmitted rotational power is reduced.
Then, the reduced turning power is transmitted to one pinion or the other pinion in the same manner as described above.

In this manner, the initially transmitted turning power is reduced and the same turning force is applied to both lower pinions, so that one of the pins which is to rotate further forward in the table. Independently of one roller or the other,
One lower side pinion and one lower side pinion mesh with the other lower side rack, respectively, and synchronize with each other while rotating in synchronism with each other for the same time.

By the operation of the base-side rotating power reduction transmission / tuning rotation mechanism, the table is slightly lowered from before loading the heavy goods, but the horizontal state is maintained and the heavy goods are placed on the table. Mounted on Thereafter, when the cylinder is moved up again, the heavy article is smoothly moved up to the predetermined height without being dropped from the table and is conveyed to the predetermined position.

According to the construction of the invention of claim (3), the situation becomes the same as that of the construction of the invention of claim (1), and when the cylinder is further operated in a state where the table is subjected to an eccentric load. In the same manner as described above, since the pivoting member is pushed open about the connecting / rotating shaft member, the scissor-link mechanism performs the sitting operation and the closing operation for further lowering the table. .

Then, one of the rollers and one of the other rollers are further taped on the upper wide rail member and the lower wide rail member, respectively. Or the other one of the rollers and the other of the other rollers are respectively on the other upper wide rail.
On the rail member and the lower wide rail member, the user tries to further rotate the table forward.

However, even in such a state, the above-described operation of the table-side rotating power reduction transmission / tuning rotation mechanism and the above-described base-side rotation power reduction transmission / tuning rotation mechanism may be performed. Since the operation is performed simultaneously on the table side and the base side of the scissor lift mechanism, the one arm or the other arm described above or the other one arm described above is used. Or other arm of the other
The movement for the closing operation of lowering the table about the pivot shaft member is more completely prevented.

Such a table-side rotating power reduction transmission
By the joint operation of the tuning rotation mechanism and the base-side rotation power reduction transmission / tuning rotation mechanism, the table is slightly lowered from before loading heavy articles, but the horizontal state of the table is accurately maintained. The heavy load, which is the source of the eccentric load, is extremely smoothly lifted to a predetermined height without being dropped from the table and conveyed to a predetermined position.

According to the structure of the invention of claim (4), the operation of the driving means on the driving body side and the driving means on the chassis side by execution of the driving operation by the operator riding on the driving body, and the outrigger-start operation (1) and (2) when the protruding operation and the downward projecting operation from one of the front and rear sides of the chassis member and the other side of the chassis member are sequentially performed by executing the above operation.
Alternatively, the lift table having an eccentric load countering structure according to claim 3 is conveyed to a predetermined loading / unloading start position, and waits for loading / unloading in a stable state where the table is kept horizontal.

Thereafter, when the position of the center of gravity of the heavy article coincides with the center position of the table, the opening operation is performed so that the scissor link mechanism stands up by the operation of the cylinder, and the table is kept horizontal. When the table moves upward and an eccentric load acts on the table as described above, in addition to the similar opening operation of the scissor link mechanism, the table side rotational power reduction transmission / tuning rotation mechanism, or The above-mentioned operation of the base-side rotating power reduction transmission / synchronous rotation mechanism, or the table-side rotating power reduction transmission /
The table on which a heavy article is mounted moves upward in a horizontal state by the above-mentioned joint operation of the tuning rotation mechanism and the base-side rotation power reduction transmission / tuning rotation mechanism.
The heavy goods mounted on the table are conveyed to a predetermined height in a horizontal state, and a lifting / unloading operation is performed.

When the above-mentioned loading / unloading work is repeatedly performed while sequentially moving the lifting / lowering starting position where the above-mentioned driving operation and outrigger start operation are performed, a predetermined lifting / unloading work cycle is repeatedly executed in a short time. In a wide area of the hoisting and unloading work site, a large number of heavy articles are all conveyed horizontally to a predetermined height.

FIG. 4 shows a case where the operation of the table-side turning power reduction transmission / tuning rotation mechanism is partially omitted, enlarged, and viewed from the front.

When the two inner arm pressing side cylinders 81 and the two outer arm pressing side cylinders 87 are simultaneously operated in order to lift a heavy article to a predetermined height and transport it to a predetermined place, Piston rod 83 and pressing force transmitting member 7
3, the pressing force generated by the inner arm pressing side cylinder 81 is transmitted to one inner arm 29 and the other inner arm 51 at the same time as the piston rod 89 and the pressing force. One of the outer arms 3 sequentially passes through the transmission member 75.
The pressing force generated by the outer arm pressing side cylinder 87 is transmitted to 9 and the other outer arm 59.

When the scissor link mechanism 71 opens and closes around the connecting / rotating shaft members 49 and 67, one upper pinion 99 meshes with one upper rack 97 by meshing. While rotating, the one inner roller 35 supports the one side 27a of the table 27 while supporting the rotation of the upper wide rail member 23 while supporting the one side 27a of the table 27. (Referred to as "rotation operation of one upper rotation group"). It should be noted that one of the outer rollers 4 is interlocked with the rotation operation.
Numeral 7 rotates on a rail surface 7a of one rail member 7.

The other upper pinion 103 is tapered.
Since the upper upper pinion 99 is interlocked with the upper upper pinion 99 via the bull-side rotating power transmission member 95, the other upper pinion 103 is connected to the upper pinion 103 at the same time as the turning operation of the one upper turning group. The other inner roller 55 pivotally supports the other side 27b of the table 27 while rotating in synchronism with the other upper rack 101 and cooperating with the meshing rotation. Is rotated on the inner side of the rail surface 25a of the upper wide rail member 25 (hereinafter referred to as the "rotation operation of the other upper rotation group"). The other outer roller 65 rotates on the rail surface 8a of the other rail member 8 in conjunction with the rotation operation.

When the pressing force acts on the scissor link mechanism 71 performing the opening / closing operation as described above, the scissor link mechanism 71 is connected to the connecting / rotating shaft members 49 and 67.
The opening operation is performed so that
The turning operation of one upper turning group and the turning operation of the other upper turning group toward the rear direction of the bull 27 (the direction of arrow A shown in FIG. 1) are simultaneously performed. As a result, the table 27 moves up in the horizontal state.

When the table 27 is moved up to a predetermined article loading position by the opening operation of the scissor link mechanism 71, the inner arm pressing cylinder 81 and the outer arm pressing cylinder 87 are moved. The operation is temporarily stopped, and the upward movement of the table 27 is stopped. Then, the heavy article is loaded on the mounting plate 13 constituting the table 27. At this time, for example, when the heavy article is mounted at a position deviated to one side of the mounting plate 13, the center of gravity of the heavy article and the table are set. -Since the center position of the table 27 does not match, most of the load of the heavy article (hereinafter referred to as "large load") on one side 27a of the table 27 and the load of the heavy article on the other side 27b. The residual load (hereinafter, referred to as “small load”) is in an eccentric load acting state in which each acts.

Then, a large load is applied to one side 2 of the table 27.
7a, the small load is transmitted to the inner roller 35 via the longitudinal reinforcing member 21 on one side and the upper wide rail member 23 constituting the table 27 in order. −
From the other side 27b of the bull 27, the longitudinal reinforcing member 2 on the other side
1. Since it is transmitted to the other inner roller 55 via the other upper side wide rail member 25 in sequence, the one inner roller
The roller 35 must support an excessive load acting in the direction of arrow A shown in FIG. 4 as compared with the other inner roller 55.

For this reason, as shown in FIGS. 1 and 4, with the loading of heavy goods, one inner arm 29 and one outer arm 39 are connected with the connecting / rotating shaft member 49 as the center. The other inner arm 51 and the other outer arm 59 are pushed and opened around the connecting / rotating shaft member 67, respectively, and a closing operation for lowering the table for a predetermined time so as to perform a sitting operation. After that, the inner arm 29 and the outer arm 39 are more likely to be pushed open about the connecting / rotating shaft member 49.

Then, the turning operation of one of the upper turning groups and the turning operation of the other upper turning group are both on the front side of the table 27 (in the direction of arrow B shown in FIG. 4). After a predetermined period of time, the rotation operation of the one upper side rotation group is further executed toward the above-mentioned front side, so that the upper side rotation group meshes with the one upper side rack 97. The turning power of one upper pinion 99 is preserved.

However, as shown in FIG. 2 and FIG.
An end of one side 95a of the bull-side rotating power transmission member 95 is interlockingly connected to one upper pinion 99 meshed with one upper rack 97, while an end of the other side 95b is above the other. Since the upper side pinion 103 meshed with the side rack 101 is interlocked and connected to both sides of the table side rotation power transmission member 95, the both sides are firmly supported.
The turning power saved in one upper pinion 99 is transmitted to the other upper pinion 103 via the table-side turning power transmission member 95.

With this transmission, immediately after the closing operation centered on the connecting / rotating shaft member 67 is stopped, the other inner arm 51 in a state where the closing operation cannot be performed any more can be performed. And the other upper pinion 103 is
Together with the other upper rack 101 of the meshing partner,
An arm re-closing operation guiding action for further forcibly performing the closing operation about the rotation shaft member 67 is performed.

Then, the other upper pinion 103 is
Since the rotation resistance is received from the other inner arm 51 together with the other upper rack 101, the rotation transmitted at the beginning is reduced by an amount corresponding to the rotation resistance and applied to the other upper pinion 103. At the same time, the reduced rotating power is transmitted to one upper pinion 99 via the table-side rotating power transmitting member 95.

When the transmission of the conserved rotational power and the application and transmission of the reduced rotational power are sequentially performed, the same force is reduced in one upper pinion 99 and the other upper pinion 103. Rotating power is applied almost simultaneously. Therefore, the eccentric load is applied to each of the turning operation of one upper turning group and the turning operation of the other upper turning group toward the front side of the table 27. In the initial stage, the upper pinion 99 is controlled by the rotation of the upper pinion 99 to be rotated and tuned to be executed at the same rotation speed for the same time.

Further, one inner arm 29 and one outer arm 39 are connected with a connecting / rotating shaft member 49 as a center, and the other inner arm 51 and the other outer arm 59 are connected with each other. The outer rollers 47 are connected to each other so as to be openable and closable about the rotation shaft member 67, so that one of the outer rollers 47 is connected to the other of the two upper rotation groups. -On the rail surface 7a of the rail member 7, the other outer roller 65 simultaneously rotates on the rail surface 8a of the other rail member 8 to the same side for the same time.

The operation of the table-side turning power reduction transmission / tuning turning mechanism 105 and the turning operation of the one outer roller 47 and the other outer roller 65 cause the table 27 to rotate. One inner roller 35 for pivotally supporting the one side 27a;
The other inner roller 46, which pivotally supports the other side 27b of the table 27, stops at a position where the rotation distance associated with the loading of the heavy article is equal, so that the table 27 is slightly less than before loading the heavy article. Although it descends, the horizontal state is maintained and a heavy article is loaded.

Thereafter, the two inner arm rotating side cylinders 81 and the two outer arm rotating side cylinders 87 described above.
Is resumed, the above-described operation of the table-side rotating power reduction transmission / tuning rotation mechanism 105 and the above-described rotation of the one outer roller 47 and the other outer roller 65 are continued. Therefore, the scissors link mechanism 71 performs the opening operation so as to stand up as described above, and the heavy article is carried on the table 27 which moves upward in a horizontal state without dropping from the table 27 or the like. . When reaching the predetermined transport position, the operation of both cylinders is stopped, and when the heavy article is unloaded from the table 27 by an appropriate unloading device or manually, the heavy article is transported to the predetermined place. .

The load supported by the outer roller 125 and the other outer roller 125 is excessively large as compared with the load supported by the other outer roller 125 together with the other inner roller 121.

For this reason, as shown in FIGS. 5 and 6, with the loading of heavy goods, one outer arm 115 and one inner arm 111 are connected with the connecting / rotating shaft member 49 as a center. The other outer arm 123 and the other inner arm 119 are pushed and opened about the connecting / rotating shaft member 67, respectively, so as to be seated, and the table is lowered for a predetermined time to perform the closing operation. Thereafter, the one outer arm 115 together with the one inner arm 111 tends to be pushed further open about the connecting / rotating shaft member 49.

Then, the turning operation of one of the lower turning groups and the turning of the other lower turning group toward the front side (the direction of arrow C shown in FIG. 5) of the table 109. Even after each of the movement operations has been performed for a predetermined time, the rotation operation of one of the lower rotation groups toward the front side is further performed, so that the rotation operation meshes with the lower rack 131. The rotational power of one lower pinion 133 is preserved.

However, as shown in FIGS. 5 and 6, the end of one side 129a of the base-side rotating power transmitting member 129 is interlocked with one lower pinion 133 meshed with one lower rack 131. While being connected, the end of the other side 129b is operatively connected to the other lower pinion 137 meshed with the other lower rack 135, so that both sides of the base-side rotating power transmission member 129 are firmly connected. Since the teeth are supported by the meshing, the turning power saved in one lower pinion 133 is transmitted to the other lower pinion 137 via the base-side turning power transmission member 129.

By such transmission, the other inner arm 119
With the other outer arm 123 immediately after stopping the above-described closing operation centering on the connecting / rotating shaft member 67 and in which the above-mentioned closing operation cannot be performed any further, and on the other lower side. The pinion 137, together with the other lower rack 135 of the mating partner, further forcibly performs the above-described closing operation about the connecting / rotating shaft member 67.
It acts to induce a reclamation action.

Then, the other lower pinion 137 is
From the other outer arm 123 to the other lower rack 135
At the same time, the rotational force transmitted at the beginning is reduced by an amount corresponding to the rotational resistance and is applied to the other lower pinion 137, and the rotational force transmitted via the base-side rotational power transmitting member 129 is reduced. The reduced turning power is also transmitted to the lower pinion 133 of the motor.

When the transmission of the conserved rotating power and the application and transmission of the reduced rotating power are sequentially performed, the lower pinion 133 and the other lower pinion 137 have the same power reduced. The turning power is applied almost simultaneously. Therefore, the turning operation of the one lower turning group and the turning operation of the other lower turning group toward the front side of the table 109 are each performed when the turning power is preserved. At the same time, the operation is performed for the same time at the rotation level suppressed by the operation of the one lower side rotation group trying to perform the rotation operation.

Further, one inner arm 111 and one outer arm 115 are connected with the connecting / rotating shaft member 49 as a center.
The other inner arm 119 and the other outer arm 123 are connected to each other so as to be openable and closable about the connecting / rotating shaft member 67.
In cooperation with the rotation of the roller, one inner roller 113 moves on the rail surface 7a of one rail member 7 and moves to the other inner roller.
The rollers 121 rotate simultaneously on the rail surface 8a of the other rail member 8 to the same side for the same time.

The operation of the base-side rotation power reduction transmission / tuning rotation mechanism 139 and the rotation of one inner roller 113 and the other inner roller 121 cause the table 109 to rotate.
Inner roller 11 for rotatably supporting one side 109a of the roller.
3 and the other inner roller 121 for rotatably supporting the other side 109b of the table 109.
Since the table 109 is stopped in a state where the rotation distance to the front side is equal, the table 109 is slightly lowered from before loading the heavy articles, but the horizontal state is maintained and the heavy articles are moved to the table.
Mounted on the bull 109.

Thereafter, in the same manner as described above, table 1
09, the above-described operation of the base-side rotation power reduction transmission / tuning rotation mechanism 139 and the above-described rotation operation of the one inner roller 113 and the other inner roller 121 continue. As a result, the heavy article is smoothly moved up to the predetermined height position and conveyed to the predetermined position without falling from the table 109 in which the horizontal state is maintained.

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 7 shows claim (3).
FIG. 8 shows a partially cut-away lift table having an offset load-bearing structure according to the embodiment of the present invention, and FIG. This shows the case when viewed from the side.

As shown in FIGS. 7 and 8, reference numeral 143 denotes a scissor link mechanism according to this embodiment, which is provided with one of the inner arms 29 provided inside and one of the inner arms 29. One of the above-mentioned ones, which is disposed outside so as to cross the inner arm 29 in an X-shape and is openably and closably connected to the one inner arm 29 via a connecting / rotating shaft member 49. Outer arm 1
15 and the other inner arm 51, which is disposed inward so as to face the one inner arm 29, intersects the other inner arm 51 in an X-shape. The other outer arm 123 is disposed outside and connected to the other inner arm 51 so as to be openable and closable via a connecting / rotating shaft member 67, and the four outer arms 123 are provided. And a connecting member 69.

As shown in FIGS. 7 and 8, the base 106, the table 27, and the scissor link mechanism 143 are described.
And the lifting / lowering power mechanism 93 and the table-side rotation power reduction transmission /
The synchronous rotation mechanism 105 and the base-side rotational power reduction transmission / synchronization rotation mechanism 139 constitute a lift table 145 having an offset load resistance structure according to an embodiment of the present invention. .

Next, an embodiment of an embodiment of the present invention will be described. When the above-described lifting power mechanism 93 is operated to move the table 27 up to the loading position of the heavy goods, the inner arm 29 and the other inner arm 51 are moved in the same manner as described above. Inside arc
The pressing force generated by the arm pressing cylinder 81 and the pressing force generated by the outer arm pressing cylinder 87 are simultaneously transmitted to one outer arm 115 and the other outer arm 123, respectively.

By the way, the scissor link mechanism 143 is
When the opening / closing operation is performed around the rotation / connection shaft members 49 and 67, as described above, the rotation operation of one upper rotation group and the rotation operation of the other upper rotation group are performed. Of the lower rotating group of the other, and the lower rotating group of the other
The rotation of the pump is performed at the same time.

When the pressing force acts on the scissor link mechanism 143 performing such opening and closing operation as described above,
The scissor link mechanism 143 includes a rotation / connection shaft member 49,
Since the opening operation is performed so as to stand around 67,
Toward the rearward direction of the table 27 (the direction of the arrow A shown in FIG. 7), the turning operation of one upper turning group, the turning operation of the other upper turning group, Lower side rotation group
As a result, the table 27 moves upward in the horizontal state and reaches a predetermined article loading position.

Thereafter, in the same manner as described above, table 2
7 is stopped and heavy articles are loaded on the table 27. At this time, if the articles are loaded in the same manner as described above, a large load is applied to one side 27a of the table 27 and a small load is applied to the other side 27b. The state is an eccentric load acting state in which loads act respectively.

Then, the large load is transmitted to the one inner roller 35 in the same manner as described above, and then the one inner
The arm 29, the pressing force transmitting member 73, the inner arm pressing side cylinder 81, the supporting member 77, and the one outer arm 115 are sequentially transmitted to one outer roller 117. On the other hand, the small load is applied to the other inner row in the same manner as described above.
After being transmitted to the roller 55, the other inner arm 51, the pressing force transmitting member 73, the inner arm pressing side cylinder 81, the supporting member 77, and the other outer arm 123 sequentially pass through the other outer arm. It is transmitted to the roller 125.

By transmitting such a large load and a small load, respectively, one inner roller 35 and one outer roller 11 are transferred.
7 is the other inner roller 55 and the other outer roller 125
Must support an excessive load acting in the direction of arrow B shown in FIG.

For this reason, as shown in FIGS. 7 and 8, one inner arm 29 and one outer arm 115 are pivoted about the rotation / connection shaft member 49 with the loading of heavy articles. The other inner arm 51 and the other outer arm 123 are pushed and opened about the connecting / rotating shaft member 67 to perform a closing operation in which the table descends for a predetermined time so as to perform a sitting operation. Later, one inner arm 29 and one outer arm 29
The arm 115 is about to be pushed and opened further around the connecting / rotating shaft member 49.

Then, the turning operation of one upper turning group and one lower turning group toward the front side of the table 27 (in the direction of arrow C shown in FIG. 7). Even after the rotation operation, the rotation operation of the other upper rotation group, and the rotation operation of the other lower rotation group have been executed for a predetermined time, respectively, one of the upper sides toward the same side is kept. The rotation operation of the side rotation group and the one lower rotation operation are about to be further executed.
One upper pinion 99 and one lower pinion 13
3 Each power is preserved.

However, as shown in FIG. 7 and FIG.
Bull-side rotating power transmitting member 95, base-side rotating power transmitting member 12
9 Since both sides are firmly supported by the teeth as described above, the rotating power saved in one upper pinion 99 is transmitted to the other upper pinion 103 via the table-side rotating power transmission member 95. The rotational power stored in one lower pinion 133 is transmitted to the other lower pinion 137 via the base-side rotational power transmission member 129.

[0135] By such transmission, in the same manner as described above,
The other upper pinion 103 is connected to the other upper rack 10
1 and the other lower arm pinion 137 together with the other lower arm 135 and the other outer arm 123 with respect to the other inner arm 51.
Since they perform the operation of inducing a reclamation operation, each of them receives the above-described rotation resistance.

Then, the initially transmitted rotational power is reduced by an amount corresponding to the rotational resistance, and the reduced rotational power is applied to the other upper pinion 103 and the other lower pinion 137, respectively, and the tape is rotated. Bull side power transmission member 9
5, and is transmitted to one upper pinion 99 via the base-side rotating power transmission member 129 to one lower pinion 133, respectively.

In this manner, one upper pinion 9
9 and between the lower pinion 133 and the other lower pinion 137, between the lower pinion 133 and the other lower pinion 137, the application and transmission of the saved rotary power and the reduced rotary power are sequentially performed. The same reduced power is applied to these pinions substantially simultaneously.

Then, at the stage where the turning power is saved, the table 27 is further moved by the turning operation of the one upper turning group and the turning operation of the one lower turning group. The turning operation of one of the upper turning groups toward the front side of the table 27 by the reduced turning power at the turning level suppressed from the turning operation to the front side, The turning operation of the lower turning group, the turning operation of the other upper turning group, and the turning operation of the other lower turning group are synchronized in the same manner as described above. Done.

By the operation of the table-side rotating power reduction transmission / tuning rotation mechanism 105 and the base-side rotation power reduction transmission / tuning rotation mechanism 139, the table 27 is slightly moved from before loading heavy articles. Although descending, the horizontal state is maintained, and when the table 27 is moved up in the same manner as described above, the heavy article is conveyed to a predetermined position in a horizontal state without dropping from the table 27.

However, it is of course applicable.

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 9 shows claim (4).
FIG. 1 shows a partially cut-away self-propelled lift table according to one embodiment of the present invention, viewed from the front.
Numeral 0 indicates a case where the self-lifting table having the structure against the uneven load according to the embodiment is partially cut and viewed from the side.

9 and the front side 149a and the rear side 149 of the other vertical frame 149, respectively.
b is an outrigger that is provided for each and performs an overhang operation or the like by the operation of the cylinder 161.

Further, 163 is the chassis member 147.
Is connected to the front side 147a of the
Below, a pair of wheels 165 and an unillustrated engine that is operatively connected to the pair of wheels 165 and is also operatively connected to the chassis-side driving force transmitting member 155 and operates by appropriate driving operation. Driving vehicle body side traveling means 1 comprising driving vehicle body side driving force transmitting member 167 connected thereto
A driving vehicle body 69 is provided.

As shown in FIGS. 9 and 10, the driving body 163, the chassis member 147, and the four outriggers
159 constitute the transportation means 171 according to this embodiment. The transportation means 171 and the chassis member 14
7. The lift table 1 having a structure against an unbalanced load according to one embodiment of the invention of claim (1), wherein the base 3 is mounted on the upper surface 147c of the vehicle 7 and mounted on the transportation means 171. A self-propelled lift table 175 having an offset load resistance structure according to an embodiment of the present invention is configured.

Next, an embodiment of an embodiment of the present invention will be described with reference to the drawings. FIG. 11 shows a case in which the lifting and lowering state of the self-propelled lift table of the present invention in the hold of an automobile transport ship according to the present embodiment is partially omitted and cut off from the lateral direction. FIG. 3 shows a vertically-cut section of the self-propelled lift table of the self-propelled lift table having the structure for counteracting eccentric load according to the embodiment in the hold, which is cut from the vertical direction and enlarged.

As shown in FIGS. 11 and 12, the interior of the hold 179 of the car transport ship 177, which is an example of a wide range of hoisting and unloading work sites, accommodates as many vehicles as possible of various heights and lengths as much as possible. In order to be able to flexibly cope with the transportation plan, each of the weight floor members 181 is large enough to mount about ten vehicles and can be lifted and lowered. It is possible that all floor members of the same level can be arranged in a predetermined space position in the hold 179 in a horizontal state so that only a small gap is generated between the upper and lower levels, and a space slightly higher than the vehicle height of the car is provided between the upper and lower levels. It is necessary to appear in such a way that it can be divided into multiple stages.

However, as shown in FIG. 11, a rectangular floor at the center of the hold 179 is easy to grasp the position of the center of gravity when carrying out the loading / unloading operation due to the shape restriction of the hull in which the wave resistance must be reduced as much as possible. Although the member 181A is provided, the side hull hold wall 179A, the bow hold wall 179B located on the bow side 177A of the car transport ship, and the stern side hold wall 179C located on the stern side 177B of the car transport ship are provided. In order to make it possible to face up close without contacting these hold walls, the facing side is formed into a curved surface, and it is extremely difficult to grasp the position of the center of gravity when performing loading / unloading. Approximate trapezoidal floor member 1
81C and a trapezoidal floor member 181D are arranged on the starboard side and the port side, respectively.

A self-propelled lift table 175 having an eccentric load countering structure according to an embodiment of the present invention as claimed in claim (4), as shown in FIG. , One level 179 in such a hold 179
The loading and unloading is started by being carried into F1, and in the preparation stage of the lifting and unloading, as shown in FIGS. 9 and 10,
When the worker gets into the driving body 163 and performs a driving operation,
The driving force of the engine (not shown) is transmitted to the pair of wheels 165 via the driving body transmitting power transmitting member 167,
Further, the driving force is transmitted from the driving type-side driving force transmitting member 167 via the chassis-side driving force transmitting member 155 to the pair of wheels 1.
53 (hereinafter referred to as “driving force transmission operation”).

Then, for example, the bow side 1 of a car transport ship
When such a driving force transmission operation is performed for a predetermined time in order to perform a predetermined lifting / unloading operation from 77A toward the stern side 177B, the lift table 1 having an eccentric load countering structure provided in the transportation means 171 is shown in FIG. As shown, it moves to the lower side of the trapezoidal floor member 181D on the starboard side.

However, in such a driving force transmission operation, it is extremely difficult to avoid collision with the fore-side hold wall 179B, and it is extremely difficult to quickly grasp the position of the center of gravity of the trapezoidal floor member 181D at the lifting / unloading work site. Therefore, trapezoidal floor member 1
81D (the same applies to the case of a trapezoidal approximate rectangular floor member 181C described later and a curved rectangular floor member 181B facing the hold wall) The center position of the mounting plate 13 constituting the table 27 at a position different from immediately below the center of gravity (Hereinafter referred to as an “unstable lifting / unloading start position due to the shape of the floor member”).
Moves to the lower side of the trapezoid floor member 181D.

Next, when the operator gets on the driving body 163 and performs an outrigger-starting operation, as shown in FIGS. 9 and 10, the cylinder 161 is operated to move the four outriggers 159 vertically downward. At the same time,
At four places around the transportation means 171 at the same time, the transportation means 171 is pushed up and supported. Then, the lift table 1 having the structure against the eccentric load holds the table 27 in a horizontal state, and waits for lifting / unloading above the unstable lifting / unloading start position due to the shape of the floor member.

Next, the pressing force is reduced by a scissor force in the same manner as described in the embodiment of the first embodiment of the present invention.
When the scissor link mechanism 71 is opened and the scissor link mechanism 71 is opened, the table 27 moves upward in the horizontal position above the unstable loading / unloading position due to the shape of the floor member. . Then, after the mounting plate 13 comes into contact with the trapezoidal floor member 181D due to the ascending movement, the trapezoidal floor member 181D is mounted on the mounting plate 13, but on the unstable lifting / unloading start position caused by the shape of the floor member. Since the mounting is started, an eccentric load acts on the table 27 in the same manner as described in the embodiment of the first embodiment of the present invention.

However, the operation of the table-side turning power reduction transmission / tuning rotation mechanism 105 described above causes the trapezoidal floor member 18 to move.
Table 27 slightly lowers at the beginning of loading 1D
Is maintained in a horizontal state. When the scissor link mechanism 71 is further raised and opened for a predetermined time, the mounting plate 13 on which the trapezoidal floor member 181D is mounted moves upward in a horizontal state, and can accommodate a vehicle having a predetermined height. The space is conveyed to a predetermined position in a horizontal state, and one loading / unloading cycle on the bow side 177A of the car transport ship 177 is executed.

Then, after one such transporting / unloading cycle is executed, the closing operation is performed so that the scissor link mechanism 71 is seated, the tape 27 is lowered to a predetermined position, and the outrigger-159 is stored. Then, the self-propelled lift table 175 having an eccentric load resistance structure has
It is ready to move toward another floor member.

Next, from the above-described driving force transmission operation, a tape operation will be described.
When the operation leading to the above-described operation of the bull-side rotating power reduction transmission / tuning rotation mechanism 105 and the above-described movement posture are repeatedly and sequentially executed, the lift table 1 equipped with the unbalanced load provided on the transportation means 171 becomes Each of the trapezoidal floor member 181D on the port side, the trapezoidal approximate rectangular floor member 181C on the port side, and the trapezoidal floor member 181D on the starboard side, each of which becomes a loading / unloading at the unstable loading / unloading start position due to the shape of the floor member. The predetermined loading / unloading cycle in which the above-described table 27 moves up and down in a horizontal state is repeatedly executed, and the predetermined loading / unloading of one level 179F1 on the bow side 177A of the car transport ship is completed.

Next, the above-described movement posture and the procedure from the appropriate driving force transmission operation to the table-side turning power reduction transmission / tuning rotation mechanism 105 described above are repeatedly and sequentially executed. Each of the self-propelled lift tables 175 having an eccentric load countering structure is moved to a position below a curved rectangular floor member 181B on the starboard side facing the starboard side, which is an unstable lifting / unloading starting position due to the shape of the floor member. Even if an unbalanced load acts on the table 27 as a loading / unloading machine from this position, a large number of starboard-side cargo hold wall-facing side curved rectangular floor members 1 are provided.
Each of the members 81B is mounted on a table 27 that maintains a horizontal state, moves upward, is conveyed to a predetermined position in a horizontal state, and has a large number of starboard-side hold-wall-facing curved-surface rectangular floor members 18.
A predetermined lifting / unloading cargo handling cycle for each of 1B is repeatedly executed.

Then, when the above-described movement posture and the appropriate driving force transmission operation are further performed, the self-propelled lift table 175 having the structure against the eccentric load can move the table 27 directly below the center of gravity of the rectangular floor member 181A. Is moved to a position near the bow near the center in the hold 179 such that the center position of the mounting plate 13 is located (hereinafter, referred to as “stable loading / unloading start position”).

Next, the above-mentioned standby for loading and unloading,
When the action of the pressing force on the slink mechanism 71 is sequentially performed, the table 27 is moved upward in the horizontal state on the stable lifting / unloading start position, and then is mounted on the stable lifting / unloading start position. The eccentric load does not act on 27, and the table 27 maintains the horizontal state and lifts the rectangular floor member 181A. When the ascending movement is stopped after continuing for a predetermined time, the rectangular floor member 181A appears in a space capable of accommodating an automobile having a predetermined vehicle height, is conveyed to a predetermined position in a horizontal state, and receives one of the rectangular floor members 181A. A lifting / unloading cycle is executed.

If the driving force transmission operation to the substantially center of the hold 179 is not performed correctly, the rectangular floor member 1
The table 27 is located at a position different from the position immediately below the center of gravity of 81A.
The lift table 1 having an eccentric load resistance structure has an adjacent rectangular floor member 181A such that the center position of the mounting plate 13 is located (hereinafter, referred to as "unstable lifting / unloading start position due to driving operation"). Move to the side.

In such a situation, when the same loading / unloading posture as described above and the opening operation for standing up the scissor link mechanism 71 are sequentially performed, the table 27 is not operated due to the driving operation for a certain period of time. Although it moves upward in the horizontal state above the stable loading / unloading start position, an unbalanced load is applied when it comes into contact with the rectangular floor member 181A and moves up further.

However, due to the above-described operation of the table-side turning power reduction transmission / tuning rotation mechanism 105, the table slightly descends at the beginning of mounting the rectangular floor member 181A.
The bull 27 is maintained in a horizontal state. When the scissors link mechanism 71 is further opened to stand up for a predetermined time, the mounting plate 1 on which the rectangular floor member 181A is mounted is mounted.
3 moves upward in a horizontal state, reveals a space capable of accommodating a vehicle having a predetermined vehicle height, is conveyed to a predetermined position in a horizontal state, and another lifting / unloading cycle for the rectangular floor member 181A is executed.

Thereafter, when the above-mentioned movement posture, the above-described procedure for the appropriate driving force transmission operation and the above-described operation of the table side rotation power reduction transmission / tuning rotation mechanism 105 are sequentially and repeatedly executed, Each of the self-propelled lift tables 175 having an eccentric load countermeasure structure is moved to a position below the port-side hold wall facing the rectangular curved floor member 181B on the port side, which is an unstable lifting / unloading starting position due to the shape of the floor member. Even when the loading / unloading operation is started from this position and an unbalanced load is applied to the table 27, each of the plurality of port-side cargo hold wall-facing side curved rectangular floor members 181B maintains the horizontal state. 27
, And is transported in a horizontal state to a predetermined position.
A predetermined lifting / unloading cargo handling cycle for each of 1B is repeatedly executed.

As described above, a large number of curved floor members 181B on the starboard side facing the holding wall, a large number of rectangular floor members 181A substantially at the center of the holding 179, a large number of rectangular floor members on the starboard side facing the holding wall. When the lifting / unloading cycle for the member 181B is sequentially and repeatedly executed, one level 179F between the bow side 177A and the stern side 177B of the car transport ship is obtained.
Predetermined lifting / unloading at 1 is completed.

Next, the above-described movement posture and the procedure from the above-described driving force transmission operation to the above-described operation of the table-side rotation power reduction transmission / tuning rotation mechanism 105 are sequentially and repeatedly performed to perform predetermined lifting and lowering. When the cargo handling cycle is executed, the predetermined lifting / unloading on one level 179F1 on the stern side 177B where the floor member similar to the bow side 177A of the car transport ship is arranged is completed, and One level 17
9F1, all rectangular floor members 181A, curved rectangular floor members 181B facing the hold wall, trapezoidal approximate rectangular floor members 18
1C and the trapezoidal floor member 181D appear in a space capable of accommodating a vehicle having a predetermined height, and are conveyed horizontally to a predetermined height position.

Then, as shown in FIG.
In the other floors 179F2, 179F3, etc., the operation of moving the self-propelled lift table 175 having an eccentric load countering structure to a predetermined height position by a similar lifting / unloading operation while repeatedly moving is repeatedly executed.

Opening / closing operation), and one of the inner arms b1 is provided near one end of the other inner arm b2 and is in contact with the back side end of the table f. The roller h1 and the other roller h2, which is an example of the other roller, are rotated. Then, the table f is moved up and down by the operation of the one roller h1 and the other roller h2, and the lifting / unloading work for lifting / unloading the articles mounted on the table f is performed. It is what you do.

[0004]

In other words, in a daily loading / unloading operation, the center of gravity of the article mounted on the table f should coincide with the center position of the table f. The lift table a is not always used for lifting and unloading work so that the unbalanced load does not act on the table f.
The position of the center of gravity of the article mounted on the table f,
Does not match the center position of the article, the center of gravity of the article is, for example,
A position closer to an edge in a direction perpendicular to the direction in which the one roller h1 and the other roller h2 rotate (hereinafter, referred to as an “eccentric position S”)
And ), The eccentric load having the eccentric position S as an action point causes one of the rollers h1 constituting the scissor link mechanism m.
Act on.

[0005] On the other hand, the lift table a has a high ability to lift heavy articles in comparison with its own weight being light, and, because of its light weight, can easily be lifted and lowered by appropriate transportation means if necessary. Since the existence value as a lifting and lowering work equipment has been found at a point that can be transported to the loading position, it has not been designed and manufactured on the premise that the above-mentioned eccentric load acts, and does not generate an eccentric load The scissor link mechanism m smoothly opens and closes the article having a predetermined weight mounted on the table f, and has sufficient rigidity to be able to carry the cargo up and down without any trouble. The arm b2, one outer arm c1, the other outer arm c2, the connecting member i, and the like are designed to be provided on respective components of the lift table a.

For this reason, when an unplanned unbalanced load acts on one of the rollers h1 when the heavy article is mounted on the table f, one of the rollers provided with one of the rollers h1 on one end side. Since the inner arm b1 does not have enough rigidity to receive a force which is not assumed in the design, the other inner arm b2 is connected to the inner arm b1.
The one inner arm b1 is pushed further open about the connecting / rotating shaft member e1 even more than being pushed open about the rotating shaft member e2.

[0007] By such an operation, the one inner arm b1
One of the rollers h1 supporting the table f and the mounted heavy article from one side is provided on the other inner arm b.
2, the table f and the other roller h2 supporting the mounted heavy article from the other side are further extended toward the front side of the lift table a (the direction of the arrow A shown in FIG. 17). Rotate for time. As a result, there is a difference in the rotational movement distance between one roller h1 and the other roller h2. As a result, the table f cannot be maintained in a horizontal state and is inclined, so that the table f is mounted. The danger of heavy articles falling is increased.

In order to avoid such a state, the thickness of the material used for each component of the lift table a such as the scissor link mechanism m is increased to increase the rigidity, and even if the above-mentioned eccentric load acts as described above, the illustrated example is adopted. Care has been taken to suppress the above-described further push-open movement of one inner arm b1.

However, when such a treatment is performed, the weight of the lift table a becomes excessively large as compared with the lifting capacity of the article, and the lift table as the above-described lifting and lowering work apparatus is used.
The value of Bull a is greatly diminished. In addition, since the situation where an unbalanced load is applied to one of the rollers h1 remains unchanged, the opening and closing structure of the scissor link mechanism m
Since the movement of one side of the scissor link mechanism, which is caused by the action of the eccentric load, to be pushed and opened more than the other side cannot be completely prevented, in consideration of an accidental drop of an article from the table, There is a certain limit to the weight of the articles mounted on the table even if the weight is excessive. Further, when the weight of the lift table is excessively increased, it is very difficult to repeatedly perform the required loading / unloading while repeatedly changing the lifting / lowering position at a wide range of loading / unloading work sites. Will happen.

The present invention has been made in consideration of the above circumstances, and has been described in connection with an operation in which one side of a scissor link mechanism is further pushed and opened from the other side due to an eccentric load acting on a table. Without changing the components of the mechanism, while maintaining the characteristics of the lift table, which is lighter than the lifting capacity, the lift table that can effectively block and counter the uneven load, and the uneven load are often Provided is a lift table having mobility so that the lift table can repeatedly execute smooth lifting / unloading operations within a short period of time in a wide range of loading / unloading work sites having an action scene. Aim.

The configuration of the invention DETAILED DESCRIPTION OF THE INVENTION claim (1), by operating the cylinder, the piston rod pressure transmitting
When a pressing force is applied by pressing the member, the pressing force
Is transmitted to each of the one arm and the other one of the arm,
It is necessary to increase the lifting force and the pressing force transmission member
A structure erected between the other arm and the other arm
If so, one other arm and the other

Then, the scissor link mechanism is opened so as to stand up.
I do.

[0025] Then, one of the position of Russia - La one of Le - Le
On the inner side of the member, the other one roller is the other rail part
Same on the inner side of the material and simultaneously on the rear side of the table
One side and the other side of the table while rotating at the rotation speed
While supporting the rotation, and cooperating with the rotation of one of the rollers.
One lower pinion meshes with one lower rack
And the other lower side in cooperation with the rotation of the other roller.
The pinion meshes with the other lower rack and rotates
At the same time, the gear rotates to the rear of the table,
The table moves upward in a horizontal state.

[0026] In this manner, it is maintained horizontal state te - after tightening made increased dynamic Bull to a predetermined position, the weight articles
Is loaded on the table, and at this time, the center of gravity of the heavy goods is
If the center position of the table does not match, one side of the table
Or, because an unbalanced load acts on the other side, one of the rollers
To one arm or the other to one roller
The acting force of the eccentric load is transmitted to the other arm via
As a result, an excessive load is applied to the arm of the opponent.

[0027] Then, one of the first A - arm or the other one of A - as arm is pushed open around the coupling and rotation shaft member, further Te - try closing occupying made drop Bull Therefore, the turning power applied to one of the lower pinions or the other lower pinion due to the loading of the heavy article on the table in a state of causing the unbalanced load is preserved.

[0028] However, even in the state of, one occupied made one of the lower rack and meshing with one of the lower side pinion, by the other of the lower pinion occupies made other lower side rack meshing, group Since both ends of the base rotation power transmission member are firmly supported by the teeth, the conserved rotation power is transmitted to the lower pinion on the mating side via the base rotation power transmission member.

[0029] Then, the mating of the lower pinion, A immediately after stopping the closing operation described above with the lower side rack meshing - A in a state in which taut on the base against the beam - beam re closing induction At this time, since the arm receives a rotational resistance from the arm, the transmitted rotational power is reduced.
Then, the reduced turning power is transmitted to one pinion or the other pinion in the same manner as described above.

[0030] In this way, since initially the transmitted rotational force the force turning force is reduced on both the lower side pinion is acting, more Te - one to be rotated to the front side of the table Independently of one roller or the other,
One lower side pinion and one lower side pinion mesh with the other lower side rack, respectively, and synchronize with each other while rotating in synchronism with each other for the same time.

[0031] By operation of the base-side rotation force reduction transmission and crustaceans rotating mechanism, Te - Bull, although slightly lowered than before wt article loading, is maintained horizontal position weight article Te - on table Mounted on Thereafter, when the cylinder is moved up again, the heavy article is smoothly moved up to the predetermined height without being dropped from the table and is conveyed to the predetermined position.

[0032] The configuration of the invention of claim (2), and the
In the same way as above, the table is loaded with specified articles in a horizontal state.
After moving it up to the
When a heavy article is loaded on a table in a state where an eccentric load is generated in the same manner as described above, one arm or the other arm is connected in the same manner as described above. As a result, the one arm or the other arm is pushed and opened about the connecting / rotating shaft member, so that a greater load is applied than the arm on the side. An attempt is made to perform a closing operation to lower the table.

[0033] Then, one of the one Russia - La and one of the other B - La and each one of the upper wide les - seal member on the one of the lower wider les - the upper seal member, further Te - Or the other one of the rollers and the other of the other rollers each have the other upper wide rail.
The heavy article is loaded on the table in a state in which an attempt is made to rotate further on the table member and the lower wide rail member toward the front side of the table, causing an eccentric load. The turning force for turning the table provided to the side pinion or the other upper pinion in front of the table is preserved.

[0034] However, even in the state of, one occupied made one of the upper rack meshed with one of the upper side pinion, by the other of the upper pinion occupies made other upper rack meshing, Te -Since both ends of the table-side rotating power transmission member are firmly supported by the teeth, the conserved rotation power is transmitted to the upper pinion on the mating side via the table-side rotating power transmission member. .

[0035] Then, the upper side pinion mating the immediately stopping the closing operation described above with upper rack meshing A - but forms a beam re-closing operation inducing action, - a relative arm
At this time, the arm receives rotational resistance from the arm, and the transmitted rotational power is reduced. Then, the reduced turning power is transmitted to one upper pinion or the other upper pinion in the same manner as described above.

[0036] In this way, since power is initially transmitted Kai is the force of rotating force is reduced on both the upper side pinion is acting, more Te - one one to be rotated to the front side of the table Independently of one roller or the other, the upper pinion is in synchronism with the upper rack and the other upper pinion.

Thus, a self-propelled lift table 175 having a structure against an eccentric load according to an embodiment of the present invention is configured.

[0135] Next, an embodiment of an embodiment of the invention of claim (3) will be described with reference to the drawings. FIG. 4 shows a case where the operation of the table-side rotating power reduction transmission / tuning rotation mechanism is partially omitted and enlarged and viewed from the front.
FIG. 12 shows a case where the lifting and lowering state of the self-propelled lift table of the present invention in the hold of an automobile transport ship according to the present embodiment is partially omitted and cut off from the lateral direction, and FIG. It shows a case in which the lifting / unloading state of the self-propelled lift table of the embodiment with the offset load resistance according to the embodiment in the warehouse is cut off from the vertical direction and enlarged.

[0136] As shown in FIGS. 11 and 12, is extensive lifting cargo handling, which is an example of a site in the hold 179 of the automobile transport ship 177, various vehicle height, as well as multi-volume housing the automobile vehicle length to the limit In order to be able to flexibly respond to a transportation plan, each of the weight floor members 181 having a size capable of mounting about ten automobiles and having a heavy weight can be moved up and down. All the floor members of the same level can be arranged in a predetermined space position in the hold 179 in a horizontal state, so that a space slightly higher than the height of the car between the upper and lower levels is formed. It is necessary to appear in such a way that it can be divided into multiple stages.

[0137] However, as shown in FIG. 11, the geometric constraints of the hull that must as far as possible not reduce wave drag, in the center of the hold 179, easily rectangular floor grasped the gravity center position when forming the lifting cargo Although the member 181A is provided, the side hull hold wall 179A, the bow hold wall 179B located on the bow side 177A of the car transport ship, and the stern side hold wall 179C located on the stern side 177B of the car transport ship are located near. In order to make it possible to face up close without contacting these hold walls, the facing side is formed into a curved surface, and it is extremely difficult to grasp the position of the center of gravity when performing loading / unloading. Approximate trapezoidal floor member 1
81C and a trapezoidal floor member 181D are arranged on the starboard side and the port side, respectively.

[0138] self-propelled Rifutote of unbalanced load counter structure according to an embodiment of the invention of claim (3) - Bull 175, as shown in FIG. 12, Siza - in a state in which Surinku mechanism 71 is folded maximally , One level 179 in such a hold 179
The loading and unloading is started by being carried into F1, and in the preparation stage of the lifting and unloading, as shown in FIGS. 9 and 10,
When the worker gets into the driving body 163 and performs a driving operation,
The driving force of the engine (not shown) is transmitted to the pair of wheels 165 via the driving body transmitting power transmitting member 167,
Further, the driving force is transmitted from the driving type-side driving force transmitting member 167 via the chassis-side driving force transmitting member 155 to the pair of wheels 1.
53 (hereinafter referred to as “driving force transmission operation”).

[0139] and, for example, bow side 1 of the automobile transport ship
When such a driving force transmission operation is performed for a predetermined time in order to perform a predetermined lifting / unloading operation from 77A toward the stern side 177B, the lift table 1 having an eccentric load countering structure provided in the transportation means 171 is shown in FIG. As shown, it moves to the lower side of the trapezoidal floor member 181D on the starboard side.

[0140] However, the driving force transmitting operation of are that it is necessary to avoid the collision with the bow side hold walls 179B, it is possible to quickly grasp the position of the center of gravity of the trapezoid floor member 181D in lifting cargo handling work site extremely difficult Therefore, trapezoidal floor member 1
81D (the same applies to the case of a trapezoidal approximate rectangular floor member 181C described later and a curved rectangular floor member 181B facing the hold wall) The center position of the mounting plate 13 constituting the table 27 at a position different from immediately below the center of gravity (Hereinafter referred to as an “unstable lifting / unloading start position due to the shape of the floor member”).
Moves to the lower side of the trapezoid floor member 181D.

[0141] Next, the operator riding on the driving body 163 is outriggers - starting the forming operation, as shown in FIGS. 9 and 10, the outrigger 159 that it vertically below the Quaternary cylinder 161 operates At the same time,
At four places around the transportation means 171 at the same time, the transportation means 171 is pushed up and supported. Then, the lift table 1 having the structure against the eccentric load holds the table 27 in a horizontal state, and waits for lifting / unloading above the unstable lifting / unloading start position due to the shape of the floor member.

[0142] Next, the unbalanced load against structure Rifutote - Bull
When the two inner arm pressing side cylinders 81 and the two outer arm pressing side cylinders 87 constituting one are simultaneously operated, one of the inner arm pressing side cylinders 81 sequentially passes through the piston rod 83 and the pressing force transmitting member 73. At the same time that the pressing force generated by the inner arm pressing side cylinder 81 is transmitted to the arm 29 and the other inner arm 51, the pressing force is sequentially transmitted through the piston rod 89 and the pressing force transmitting member 75. The pressing force generated by the outer arm pressing cylinder 87 is transmitted to the outer arm 39 and the other outer arm 59.

[0143] Incidentally, Siza - Surinku mechanism 71, when the opening and closing operation around the coupling and rotation shaft members 49,67, one of the upper pinion 99, meshing with meshing with one of the upper rack 97 While rotating, the one inner roller 35 supports the one side 27a of the table 27 while supporting the rotation of the upper wide rail member 23 while supporting the one side 27a of the table 27. (Referred to as "rotation operation of one upper rotation group"). It should be noted that one of the outer rollers 4 is interlocked with the rotation operation.
Numeral 7 rotates on a rail surface 7a of one rail member 7.

[0144] The other of the upper pinion 103 Gath -
Since the upper upper pinion 99 is interlocked with the upper upper pinion 99 via the bull-side rotating power transmission member 95, the other upper pinion 103 is connected to the upper pinion 103 at the same time as the turning operation of the one upper turning group. The other inner roller 55 pivotally supports the other side 27b of the table 27 while rotating in synchronism with the other upper rack 101 and cooperating with the meshing rotation. Is rotated on the inner side of the rail surface 25a of the upper wide rail member 25 (hereinafter referred to as the "rotation operation of the other upper rotation group"). The other outer roller 65 rotates on the rail surface 8a of the other rail member 8 in conjunction with the rotation operation.

[0145] Such Siza forms an opening and closing operation - When was as described above in Surinku mechanism 71 pressing force is applied, Siza - Surinku mechanism 71 is consolidated and the rotation shaft member 49,67
The opening operation is performed so that
The turning operation of one upper turning group and the turning operation of the other upper turning group toward the rear direction of the bull 27 (the direction of arrow A shown in FIG. 1) are simultaneously performed. .

[0146] Then, Te - table 27 rises dynamic instability lifting cargo handling position above that due to the shape of the floor members in a horizontal state. Then, after the mounting plate 13 comes into contact with the trapezoidal floor member 181D due to the ascending movement, the trapezoidal floor member 181D is mounted on the mounting plate 13, but on the unstable lifting / unloading start position caused by the shape of the floor member. Since loading was started, heavy goods
Center of gravity of table 27 with center of gravity of a trapezoidal floor member 181D
Since the positions do not match, one side 27 of the table 27
a shows a large part of the load of the trapezoidal floor member 181D (hereinafter referred to as "large load").
"Heavy". ) Is the load of the heavy article on the other side 27b.
Residuals (hereinafter referred to as "small loads") act on each
An eccentric load is applied.

[0147] As a result, a large load tape - one side 2 of the cable 27
7a, the small load is transmitted to the inner roller 35 via the longitudinal reinforcing member 21 on one side and the upper wide rail member 23 constituting the table 27 in order. −
From the other side 27b of the bull 27, the longitudinal reinforcing member 2 on the other side
1. Since it is transmitted to the other inner roller 55 via the other upper side wide rail member 25 in sequence, the one inner roller
The roller 35 must support an excessive load acting in the direction of arrow A shown in FIG. 4 as compared with the other inner roller 55.

[0148] Therefore, as shown in FIGS. 1 and 4, with the loading of the weight articles, one of the inner A - around the arm 39 is connected, the rotation shaft member 49, - arm 29 and one of the outer A The other inner arm 51 and the other outer arm 59 are pushed and opened around the connecting / rotating shaft member 67, respectively, and a closing operation for lowering the table for a predetermined time so as to perform a sitting operation. After that, the inner arm 29 and the outer arm 39 are more likely to be pushed open about the connecting / rotating shaft member 49.

[0149] Then, one of the upper side rotary Group - flop rotary movement and the other of the upper side rotary Group - each rotation of flop Te - front side of the table 27 (arrow B direction shown in FIG. 4) After a predetermined period of time, the rotation operation of the one upper side rotation group is further executed toward the above-mentioned front side, so that the upper side rotation group meshes with the one upper side rack 97. The turning power of one upper pinion 99 is preserved.

[0150] However, as shown in FIGS. 2 and 4, Te -
An end of one side 95a of the bull-side rotating power transmission member 95 is interlockingly connected to one upper pinion 99 meshed with one upper rack 97, while an end of the other side 95b is above the other. Since the upper side pinion 103 meshed with the side rack 101 is interlocked and connected to both sides of the table side rotation power transmission member 95, the both sides are firmly supported.
The turning power saved in one upper pinion 99 is transmitted to the other upper pinion 103 via the table-side turning power transmission member 95.

[0151] According the transmission, if it is immediately after the stop the closing operation described above with a focus on consolidated and the rotation shaft member 67, the other inner A whose status can not closing operation described above further - to arm 51 And the other upper pinion 103 is
Together with the other upper rack 101 of the meshing partner,
An arm re-closing operation guiding action for further forcibly performing the closing operation about the rotation shaft member 67 is performed.

[0152] Then, the other of the upper pinion 103,
Since the rotation resistance is received from the other inner arm 51 together with the other upper rack 101, the rotation transmitted at the beginning is reduced by an amount corresponding to the rotation resistance and applied to the other upper pinion 103. At the same time, the reduced rotating power is transmitted to one upper pinion 99 via the table-side rotating power transmitting member 95.

When the transmission of the conserved rotating power and the application and transmission of the reduced rotating power are sequentially performed, the one upper pinion 99 and the other upper pinion 103 have the same power reduced. Rotating power is applied almost simultaneously. Therefore, the eccentric load is applied to each of the turning operation of one upper turning group and the turning operation of the other upper turning group toward the front side of the table 27. In the initial stage, the upper pinion 99 is controlled by the rotation of the upper pinion 99 to be rotated and tuned to be executed at the same rotation speed for the same time.
