Please consult Fig. 1,2,3 simultaneously, first embodiment includes a pedestal 10, a fixed cylinder 20, one movable cylinder 30, a lift component 40, a connector 50, this fixed cylinder 20 and this lift component 40 vertically are located on this pedestal 10, and this fixed cylinder 20 is parallel with this lift component 40.Carry out lifting action and should activity cylinder 30 be installed on this lift component 40 and drive, and should also be parallel with this fixed cylinder 20 by activity cylinder 30 by this lift component 40.This connector 50 has the one first and first guiding frame 51,52 are installed in respectively on this fixed cylinder 20 and this activity cylinder 30, and this connector 50 is provided with at least one embedding hole 53 and embeds for a rolling assembly 54, and with a lock member 55 with 54 lockings of this rolling assembly on this connector 50, and this connector 50 is provided with at least two guide rods 60,61 respectively to should fixed cylinder 20 with this activity cylinder 30 on guide channel 62,63 and carry out lifting guiding, guide rod 60 of the present utility model, 61 can be located at this connector 50 above or below, can not influence time of installation process to make things convenient for the staff arbitrarily to assemble.All rectangular structure etc. or other geometry of first and first of this fixed cylinder 20, movable cylinder 30 and this connector 50 guiding frame 51,52 wherein.
This fixed cylinder 20 can be one-body molded with this activity cylinder 30, or utilize four rectangular slabs 21,31 and top board 22,32 to assemble.These four rectangular slabs 21,31 and top board 22,32 can utilize bolt 23,33 lockings.
This connector 50 consists essentially of a spacing block 56, one left and right short slab 57 and a forward and backward long slab 58 combines, the both end sides of this spacing block 56 is this forward and backward long slab 58 of interlocking respectively, again will these left and right short slab 57 interlockings on the both end sides of this forward and backward long slab 58 to form this first guiding frame 51 and this second guiding frame 52, the first guiding frame 51 of this connector 50 is in the same plane with this second guiding frame 52.Wherein this rolling assembly 54 is located in the embedding hole 53 on the left and right short slab 57 of these connector 50 opposite sides.
As shown in Figure 1, this lock member 55 is a rectangular block shape, and is provided with a groove 551 in middle position, makes the screw 552 that is respectively equipped with three tandems on this lock member 55, for several screw rods 553 with these lock member 55 lockings on this connector 50.
See also Fig. 4, the embedding hole 53 on the connector 50 among second embodiment embeds for this rolling assembly 54, and locks from the preceding long slab of this connector 50 or the screw 571 on the long slab 58 of back with this lock member 55, and with these rolling assembly 54 lockings.As shown in Figure 4, this lock member 55 is a bolt 555, can reduce manufacturing cost and reduce built-up time.
The rolling assembly 54 of first or second embodiment is the needle roller bearing assembly.This rolling assembly 54 has a main shaft 541, and is equiped with two mobilizable needle bearings 542 on this main shaft 541, and this two needle bearing 542 is provided with a lining 543, so, this needle bearing 542 is rotated and can not run foul of each other.As shown in Figure 4, wherein these main shaft 541 both sides need not have tangent plane, because it does not need as shown in Figure 1, need lock member 55 lockings.And as shown in Figure 1, these main shaft 541 both sides need have a tangent plane 544, are screw rod 553 packings of locking screw 552 on the groove 551 of this lock member 55 for making, so, just can make this needle bearing assembly by packing on these cylinder 20,30 walls.
First and second guiding frame 51,52 of connector 50, that is long slab 58 inwalls are provided with a plurality of circular grooves 581, for a plurality of anti-wear components 582 devices in this circular groove 581, and to this fixed cylinder 20 and these activity cylinder 30 packings.Wherein the tangent plane 544 of main shaft 541 both sides of this rolling assembly 54 promptly is screw rod 553 packings of locking screw 552 on the groove 551 of this lock member 55 for making, so, just can make these needle bearing 54 assemblies by packing on these cylinder 20,30 walls.
This lift component 40 has a liftable axostylus axostyle 41, and the cylinder alive 30 of this hollow is installed on this axostylus axostyle 41, the top of this activity cylinder 30 is provided with a circular hole 34 and four lockholes 35 in order to the carrier 70 that locks, as shown in Figure 5, can hold in the palm and for the axostylus axostyle 41 of this lift component 40 and to make this activity cylinder 30 and drive this activity cylinder 30 liftings.These activity cylinder 30 tops are to be convenient to the carrier of transferring in conjunction with this carrier.
Please consult Fig. 5,6 simultaneously, this lowering or hoisting gear device is in an operating-table, in order to support carrier 70, i.e. an operation table.When this carrier 70 needed to rise, these lift component 40 actions promoted this activity cylinder 30 and move up, and should up push away this carrier 70 by activity cylinder 30 this moment, can promote this carrier 70 and move up.When this activity cylinder 30 moves to these guide channel 63 bottoms, can prop up the guide rod 60 on the connector 50 and drive this connector 50 and rise.Prop up this guide rod 61 when this connector 50 rises to, then this guide rod 61 can move along this guide channel 62.So, utilize this connector 50 to link this fixed cylinder 20 and this activity cylinder 30, moment arm is widened, the stability when increase lifting degree is done and the lowering or hoisting gear of balance.Simultaneously rolling assembly 54 is set, the moment when promptly the needle bearing assembly can be strengthened lifting action, imbalance when avoiding lifting in these connector 50 both sides.When this activity cylinder 30 is urged to peak by this lift component 40, can reduce the required remaining space of the axostylus axostyle 41 rising limit of traditional lift component 40 in addition, therefore, lift component 40 is promoted arrive the highest summit.Embodiment of the present utility model can increase to knotty cylinder at movable cylinder 30 or lift component 40 parts, with the multiplication stroke.And this carrier 70 can be locked in movable cylinder 30 tops, also can be locked in the oil hydraulic cylinder top, can increase different adjustment, and stability and balance when not influencing lifting.
Please consult Fig. 7,8,9 simultaneously, main difference is that the first guiding frame 51 of this connector 50 is non-in the same plane with this second guiding frame 52 in first and second embodiment, uses so that the stroke of this lowering or hoisting gear increases.
This first guiding frame 51 is connected with a sloping portion 59 respectively with this second guiding frame 52 and forms connector 50, and the second guiding frame 52 is low as the first guiding frame 51 is high, or second guides frame 52 height and first to guide frame 51 low.54 of rolling assemblies are located at the upper and lower plane of this first and second guiding frame 51,52 respectively and are the diagonal side place, and lock with lock member 55 packings.The upper and lower plane and another diagonal side place that guide frame 51,52 simultaneously in this first and second are provided with anti-wear component 582.
In addition, present embodiment is for constituting the selection of different strokes, can be provided with the guide channel of the different strokes of complex trace in this activity cylinder 30 or this fixed cylinder 20, numbering 63 as Fig. 1, and, the upward stroke of this activity cylinder 30 is controlled, therefore by this guide channel to be located at guide rod 583 these guide channels of guiding on this connector 50, by different strokes, that is the guide channel of different length is guided movable cylinder 30 and is made upward stroke.
By upper each embodiment as can be known, the utility model can reach following characteristics and effect '
