Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a track changing device for a bogie, and particularly to a bogie suitable for changing the track of a bogie placed on a certain track to a plurality of other tracks arranged parallel to the track. This invention relates to a trajectory changing device.

In general, when viewed from a two-dimensional perspective, railroad tracks, the inside of a ship's bottom, a steel floor under construction, spectator seats at a stadium, etc., can be regarded as tracks on which bogies can run.

For example, as shown in FIG. 1, a large number of stringers are laid inside the bottom of a ship under construction or at the bottom of an oil tank of an oil tanker, and these stringers can be regarded as rails 1.

Further, as shown in FIG. 2, the steel frame floor surface under construction is formed in a lattice shape when viewed from above, and the parallel members can be regarded as rails 1.

Furthermore, as shown in Figure 3, handrails are provided in front of the seats in stadiums, etc., and these handrails also have parallel rails.
It can be understood as

Among these rails 1, two adjacent parallel rails are considered as a track, and a cart corresponding to various purposes is placed on this track, and various items for cleaning or other work are placed on this cart. If equipment, tools, etc. are loaded and the cart is moved along the track, work can be carried out smoothly.

For example, in Fig. 1, a cart equipped with cleaning equipment is placed on two adjacent rails 101 and 102 of the rails 1, and the work is started from the left end in the figure, and the work is started from the far right side in the figure. At the same time, the trolley is moved toward the rear end, and when it reaches the far end, it is crossed to the adjacent tracks, that is, rails 102 and 103, and the work is continued by moving the trolley in the opposite direction to the left in the figure. This allows you to easily clean the inside of the ship's bottom.

There is no problem if you place the bogie on the track and run it along the track, but if you cross the track and move the bogie to the next track, in other words, if you change the track, There are obstacles and it is not easy.

If the trolley is lightweight, it is possible to lift it manually and change the trajectory, but since the trolley usually has various equipment mounted on it, there is a limit to the work that can be done, and it requires multiple people. There is a drawback.

If the bogie is heavy, a lifting machine or other track changing device is required, and track changes cannot be made in locations without such equipment, thus requiring a separate bogie or track changing device. It is necessary to provide a separate

However, such devices require a large amount of space,
It is difficult to separately install various devices in a narrow and limited space.

For example, in the case of railways, the track is changed by point switching, but this point switching device requires a large space in the longitudinal direction of the track, and it cannot be used in narrow spaces such as the inside of the bottom of a ship or in a limited space. Therefore, it is difficult to separately provide a trajectory changing device such as the point switching device.

The present invention was made in view of the above points, and it is possible to easily change the trajectory of a bogie in a limited space without providing a separate device for changing the trajectory, thereby improving work efficiency. The object of the present invention is to provide a bogie track changing device that can significantly improve the performance.

In the present invention, a track changing wheel is attached to a bogie via an elevating member, a delivery beam extending in a direction perpendicular and parallel to the track is movably supported on the track changing wheel, and the delivery beam is lowered by the elevating member. As a result, the truck itself is raised from the track, and the bridge moves the truck along the transfer beam, making it possible to easily change the track.

The present invention will be described below based on embodiments shown in the drawings.

Note that the term "track" here refers to a set of two rails among the rails 1 arranged in parallel.

Further, although the rail 1 is in the shape of an H-shaped steel, it is not limited to this, and may be of any shape as long as it can carry a trolley and allow the seats and wheels to roll.

As shown in Figures 4 to 6, fixed wheels 3, 3 and 4, 4 are arranged at almost four corners on the bottom surface of the trolley 2 on which various equipment can be placed. wheels 4,4
In order to prevent derailment, a collar 4A is formed respectively.

The fixed wheels 3 and 4 are placed on a track consisting of rails 101 and 102 and can run, but in the figure, the fixed wheels 3 and 4 are

An electric cylinder mechanism 5 is attached to one side of the truck 2 as a drive source for raising and lowering a lifting member to be described later, and a rack 8 is attached to the tip of a plunger rod 6 of the electric cylinder mechanism 5 via a clevis 7. It is being

This rack 8 is slidably fitted into a guide plate 9 attached to the side surface of the truck 2, and the plunger rod 6
It can be moved along the guide plate 9 by expanding and contracting.

A pinion 10 is engaged with this rack 8, and a shaft 11 of this pinion 10 is rotatably supported by brackets 12, 12 attached to the guide plate 9, and protrudes through the bracket 12 in one direction. has been done.

A sprocket 13 is fitted onto the protruding end of the shaft 11.

The rotation of the sprocket 13 is transmitted to a drive transmission shaft 15 of a lifting device 14 that lifts and lifts the truck 2 from the track surface when changing the trajectory.

That is, the lifting device 14 is attached to the four corners of the trolley 2,
Of these, two lifting devices 1 are adjacent to each other in a direction perpendicular to the track.
A sprocket 16 is fitted to the end of a drive transmission shaft 15 that connects 4.14 so as to transmit power, and this sprocket 16 and the sprocket 13 are meshed with each other via a chain 17.

The other two lifting devices 14.14 on the right side of the figure are also communicably connected to each other by a drive transmission shaft 15, and a sprocket 18 is fitted to the end of the drive transmission shaft 15.

A sprocket 19 is also fitted to the drive transmission shaft 15 which is directly rotated by the sprocket 16.

These sprockets H8 and 19 are meshed with each other through a chain 20 so as to be able to transmit power, and guide sprockets 21 and 21 are used to adjust the tension of the chain 20 and prevent it from swinging.
is attached to the truck.

Therefore, all the lifting devices 14 are operated by the electric cylinder mechanism 5 which is a driving source.

The elevating device 14 incorporates column-shaped elevating members 22 that can be raised and lowered, and the elevating members 22 penetrate the cart 2 vertically.

Although the mechanism for raising and lowering the lifting member 22 is not shown, a known means such as a rack and pinion may be used.

In the figure, reference numeral 23 indicates a rack formed on the outer periphery of the elevating member 22. As shown in FIG.

A bracket 24 is attached to the lower end of the elevating member 22, and a delivery beam 25 is supported on the bracket 24 via track changing wheels 26 so as to be movable in the longitudinal direction.

Here, the trajectory changing wheels 26 include a wheel 26A that rolls on the upper surface of the delivery beam 25 and two wheels 26B, 26B that roll on the side surface of the delivery beam 25 or the lower surface of the flange portion.
It is composed of.

Further, the delivery beam 25 extends in a direction perpendicular to the track, and extends along at least another track provided adjacent to the track on which the bogie 2 runs.

Further, although the delivery beam 25 has the shape of an H-beam in this embodiment, it is not limited to this.

One delivery beam 25 is provided for the lifting device 14.14 connected by the one drive transmission shaft 15,
In this embodiment, two are arranged on both sides of the trolley 2.

Further, the delivery beam 25 is raised and lowered by the lifting device 14 via the lifting member 22, and at least when descending, it is lowered to a position lower than the fixed wheels 3 and 4.

In particular, the state shown in FIG. 4 shows a state in which the delivery beam 25 has descended below the fixed wheels 3, the delivery beam 25 has been placed on the track, and the truck 2 has been lifted off the track.

Further, in this state, the truck 2 can travel along the delivery beam 25 via the track changing wheels 26.

Further, as shown in FIG. 6, stoppers 27 and 28 are provided near both ends of the delivery beam 25.
．． The inner side dimension M of 28 is equal to twice the pitch P of each rail plus the width N of the lower end bracket 24 of the elevating member 22, that is, M=2P+N.

However, this is 1 for rail 1 arranged at pitch P.
This is the dimension for changing the trajectory in pitch increments. If the trajectory is changed in 2 pitch increments, M=3P+N, and if the trajectory is changed in 3 pitch increments, M=4P+N.
becomes.

Next, the operation of the bogie track changing device configured as above will be explained.

First, the bogie 2 has fixed wheels 3 and 4 with rails 101°102
It shall be placed on the top surface of the

From this state, the lifting device 14 is operated to lower the delivery beam 25 relative to the truck 2.

These movements are made by first actuating the plunger rod 6 by the electric cylinder mechanism 5, which is the driving source, and then moving the rack 8,
The pinion 10, shaft 11, and sprocket 13 are rotated.

This rotation is transmitted via the chain 17 to the drive transmission shaft 15 on the left side of FIG. 5 via the sprocket 16, and this drive transmission shaft 15 is also transmitted via the chain 20 to the drive transmission shaft 15 on the right side of the figure be done.

As a result, all the lifting devices 14 are activated at the same time, and the lifting member 22 is lowered.

When the delivery beam 25 supported at the lower end of the elevating member 22 via the track changing wheels 26 descends relatively below the fixed wheels 3 and 4, the delivery beam 25 moves from the upper surface of the rails 101, 102, 103. When the elevating member 22 further descends, the fixed wheels 3,
A certain amount of clearance is created between the transfer surface of No. 4 and the upper surface of the rails 101, 102, that is, the truck 2 is lifted off from the rails 101, 102, and in this state, the operation of the lifting device 14 is stopped.

This condition is shown in FIG. 7A. In this case, trolley 2
can run along the transfer beam 25 via trajectory changing wheels 26.

Next, as shown in FIG. 7B, the trolley 2 is moved along the delivery beam 25 in the direction of the rail 103 by human power, for example, and the side end of the bracket 24 at the lower end of the lifting member 22 is attached to the delivery beam 25. The carriage 2 is stopped by hitting the stopper 28.

At this time, the fixed wheels 3 and 4 of the bogie 2 are connected to the rails 102 and 10.
It is correctly positioned on the orbit consisting of 3.

Next, as shown in FIG. 7C, the lifting device 14 is operated in the opposite direction to raise the lifting member 22 relative to the truck 2.

That is, by operating the electric cylinder mechanism 5, which is a driving source, in the opposite direction, the truck 2 is lowered in the opposite direction along the elevating member 22, and the fixed wheels 3 and 4 finally come into contact with the rails 102 and 103.

By further continuing the operation of the lifting device 14, the lifting member 22 now begins to rise relative to the truck 2, causing the transfer beam 25 to lift off from the rails 102 and 103.

This state is shown in the seventh diagram, and the trolley 2 is
from rails 101 and 102 to rails 102 and 103
The orbit will be changed to .

The state shown in FIG. 7C is a transitional state in which the entire weight of the truck 2, which was supported by the four elevating members 22 via the track changing wheels 26, is transferred to the fixed wheels 3 and 4.

Next, when changing the track of the bogie 2 from the track consisting of the rails 102 and 103 to the track consisting of the rails 103 and 104, first, in the state shown in the seventh diagram, the delivery beam 2
5 is freely movable with respect to the truck 2, and the delivery beam 25 is moved in the direction of the track 104 by, for example, human power, and the stopper 27 provided on the delivery beam 25 is moved to the side end of the lower end bracket 24 of the lifting member 22. Place it on the area and stop.

This condition is shown in FIG. 7E. Next, by operating the electric cylinder mechanism 5 and the elevating device 14, which are the driving sources, the elevating member 22 is lowered relative to the trolley 2. The supported delivery beam 25 is connected to the rails 102, 10.
3 and the upper surfaces of 104 to form a state as shown in FIG. 7F.

That is, F indicates a transitional state in which the entire weight of the truck 2, which was supported by the fixed wheels 3 and 4, is transferred to the track changing wheels 26.

After that, by repeating the same action as described above, the trolley 2
is the rail 103,1 from the track consisting of the rails 102,103.
The orbit is changed to an orbit consisting of 04.

In this way, according to this embodiment, by repeating the above operations, the trajectory can be changed to an unspecified trajectory as many times as desired, and it is also easy to change the trajectory in the opposite direction to the above-mentioned trajectory change. can be done.

In this way, according to this embodiment, even though human power is used, the trolley 2
One worker is sufficient to move and change the trajectory, simplifying and increasing the efficiency of the work, and the simple structure allows for inexpensive manufacture.

In addition, it has sufficient safety and can be an economical and versatile trajectory changing device.

In this embodiment, the trajectory change movement of the delivery beam and the truck at the time of trajectory change was performed manually, but there is no need to be limited to this, and automation can be achieved by providing a separate traveling movement drive source or delivery power source, for example. , labor saving can be easily achieved, and remote control is also possible.

Further, in this embodiment, the lifting devices 14 operate simultaneously, but it may be necessary to adjust the height when placed on the initial orbit, so each lifting device 14
The elevating member 22 may be driven separately, and the elevating member 22 may have a longer or shorter length to correspond to the height of the rail.

In this way, a wider range of applications can be obtained.

Further, in this embodiment, the electric cylinder mechanism 5 is provided as a drive source, but it is not necessary to be limited to this, and it goes without saying that a rotary type or other drive source may be used.

Furthermore, although the term "track" refers to a set of adjacent rails, there is no need to limit it to this, for example, a set of adjacent rails.
A set of rails or just one rail can be used as a rail.

As described above, according to the present invention, the trajectory of the truck can be easily changed with an extremely simple structure, and therefore, there is an excellent effect that labor saving and high efficiency can be achieved.
