As shown in fig. 1, a slope lift elevator for a trench in a garage according to an embodiment of the present application includes a platform 21, a side plate 22, and a reciprocating driving mechanism.

Wherein the two side plates 22 are respectively and relatively parallel fixed on the two side walls 103 of the trench 101 by fasteners such as, but not limited to, bolts. The side plates 22 are arranged in parallel in the longitudinal direction of the pit 101 in the ascending or descending direction of the step ladder 102, i.e. the side plates 22 are obliquely arranged in the pit 101. In the embodiment of the present application, the side plate 22 may be alternatively in the shape of a parallelogram as illustrated in fig. 1, wherein the top of the side plate 22 is not higher than the ground 105, and the bottom of the side plate 22 is fixed to the bottom 104 of the trench 101. In this way, both the sides and bottom of the side panels 22 are firmly secured within the trench 101 to provide stable support and accurate restraint for movement of the platform 21.

Along the length of the side plates 22, a movement path of the platform 21 is provided. Since the longitudinal direction of the side plates 22 is parallel to the upward or downward direction of the steps 102 in the trench 101, the movement path is also inclined parallel to the upward or downward direction of the steps 102, which makes the movement of the platform 21 along the upward or downward direction of the steps 102, and the platform 21 does not interfere with the steps 102 during the movement, but corresponds to an extension of the steps 102. Preferably, the top of the platform 21 is flush with the ground 105 as the platform 21 moves to the top of the trench 101; the top of the platform 21 may be considered flush with the tread of the lowest first step 102 as the platform 21 moves to the bottom 104 of the trench 101, such an arrangement may allow the platform 21 to more smoothly traverse between the ground 105, the platform 21, the steps 102, the bottom 104 of the trench 101 as the platform 21 is being transported for equipment and personnel.

The reciprocating drive mechanism is provided between the platform 21 and the side plates 22, and the platform 21 reciprocates along the movement path between the two side plates 22 by the reciprocating drive mechanism.

In this embodiment, the two side plates 22 are respectively fixed on two side walls 103 of the trench 101, and the platform 21 reciprocates in the trench 101 along the ascending or descending direction of the step ladder 102 along the movement path between the two side plates 22 to complete the transportation of equipment and personnel between the ground and the trench. In addition, the top of the side plate 22 is not higher than the ground 105, and the platform 21 can descend to the bottom 104 of the trench 101 when not in use, and the platform 21 is positioned at the bottom 104 of the trench 101, so that normal walking of staff on the step ladder 102 in the trench 101 is not influenced, the normal operation of a locomotive is not influenced by the whole device, and the transportation of equipment and staff can be realized between the ground 105 and the bottom 104 of the trench 101.

As an alternative embodiment, as shown in fig. 2-4, the reciprocating drive mechanism may include a drive motor 27, a worm gear reducer 28, and at least one pair of cooperating racks 212 and drive gears 211.

As shown in fig. 4, the driving motor 27 and the worm gear reducer 28 are fixedly mounted in the platform 21 by fasteners including, but not limited to, bolts, etc., and the driving motor 27 and the worm gear reducer 28 are in driving connection.

As shown in fig. 2, the rack 212 is fixedly disposed on a side of the side plate 22 near the platform 21 along a length direction of the side plate 22.

When there is only a pair of rack 212 and drive gear 211 used in cooperation with each other, one end of the worm gear worm speed reducer 28 extends from the inside of the platform 21 to the outside of the platform 21. The rack 212 is fixedly disposed on the side plate 22 adjacent the extended end of the worm. The drive gear 211 is fitted to the extended end of the worm by means of, for example, a key connection, etc., and is engaged with the rack 212. Although such a one-side driving method can also drive the platform 21 to move, the uneven stress on both sides of the platform 21 may cause the platform 21 to move in a locked manner or have insufficient power.

Therefore, it is conceivable to use two pairs of the rack 212 and the drive gear 211 that are used in cooperation with each other, and at this time, both ends of the worm gear 28 extend from the inside of the stage 21 to both sides of the outside of the stage 21, respectively. The two racks 212 are fixedly provided on the two side plates 22, respectively, and are parallel to each other. The two driving gears 211 are respectively fitted to both ends of the worm by means of, for example, a key connection, and the two driving gears 211 are respectively engaged with the two racks 212. The double-sided driving manner can provide a more powerful driving force for the platform 21, so that the movement of the platform 21 is smoother and smoother.

Since the worm of some worm gear worm speed reducers 28 may not be long, it cannot extend outside the platform 21. In this regard, as shown in fig. 4, it is conceivable to add the coupling 29 and the rotation shaft 210 to meet the assembly requirement of the driving gear 211. One end of the rotating shaft 210 is connected to an end of a worm of the worm gear and worm speed reducer 28 through the coupling 29, and the other end extends to the outside of the platform 21 and is fitted with the driving gear 211. The coupling 29 also enhances the flexibility of the transmission between the shaft 210 and the worm of the worm gear worm reducer 28 and also reduces the relative accuracy of the installation therebetween. Bearings can be further installed between the rotating shaft 210 and the platform 21 to limit the rotating shaft 210 and enhance the stability of the rotating shaft 210 during rotation.

It should be further noted that, the driving motor 27 drives the worm wheel in the worm gear reducer 28 to rotate, and then the worm wheel drives the worm to rotate, and this transmission process is smooth, that is, the platform 21 is driven to move by the driving motor 27 without any obstacle. When driving motor 27 stops rotating, under the action of gravity, platform 21 has the trend of downward movement, but because turbine worm reducer 28 possesses the self-locking function, the rotation of worm can't drive turbine rotation, still can't further drive driving motor 27 and rotate, so platform 21 can't remove after driving motor 27 stops rotating, and this self-locking feature that this application embodiment can rely on turbine worm reducer 28 realizes the fixed of platform 21 position. The driving motor 27 and the worm gear reducer 28 are arranged in the platform 21, so that space is greatly saved, construction difficulty is reduced, and the device is very suitable for being applied to the places of ditches in a locomotive garage.

For the movement path of the platform 21, it may be formed by a guide rail 25 and a weight-bearing roller 24. For example, as shown in fig. 1 and 2, at least one guide rail 25 is fixedly disposed on each side plate 22, and the guide rail 25 is disposed along the length direction of the side plate 22, that is, the guide rail 25 is disposed obliquely parallel to the rack 212, so as to ensure that the movement direction of the platform 21 along the guide rail 25 and the driving force generated by the driving gear 211 on the platform 21 through the rack 212 are in one direction.

As shown in fig. 2 and 3, at least one bearing roller 24 is rotatably connected to the platform 21 at a position corresponding to the guide rail 25, and the bearing roller 24 abuts against the guide rail 25. I.e. the load-bearing rollers 24 can roll on the guide rails 25, thereby defining a movement of the platform 21 along the length of the guide rails 25.

If the equipment or personnel being transported on the platform 21 is heavy, the platform 21 may be tilted or otherwise deflected in motion. In order to suppress this, as shown in fig. 2, the embodiment of the present application may consider that two guide rails 25 are fixedly provided on each side plate 22, and the two guide rails 25 are parallel and spaced apart to average the pressure of the platform 21.

The corresponding measures are as follows: the two bearing rollers 24 may be rotatably connected to the platform 21 at positions corresponding to each guide rail 25, and the two bearing rollers 24 are disposed at intervals along the length direction of the guide rail 25, so as to further uniformly spread the pressure of the platform 21.

To further prevent the platform 21 from deflecting, as shown in fig. 3 and 5, embodiments of the present application may further include guide rollers 26. At least one guide roller 26 is rotatably connected to the platform 21 at a position corresponding to the guide rail 25. The guide rollers 26 are located between the guide rail 25 and the platform 21. The rolling surface of the guide roller 26 and the side surface of the guide rail 25, which is close to the platform 21, are arranged at a certain distance, so that a certain floating space is obtained for the platform 2, and the requirement on installation precision is reduced. The guide rollers 26 can contact the guide rail 25 when the platform 2 is deviated, and correct the movement path of the bearing rollers 24. Preferably, one guide roller 26 is provided for each of the load-bearing rollers 24 to obtain a better guiding effect.

The contact surface between the bearing roller 24 and the guide rail 25 can be a plane, or a V-shaped surface or an arc surface can be adopted to further improve the guiding effect.

In order to achieve stable fixation of the bottom of the side plate 22, as shown in fig. 1 and 2, the embodiment of the present application may further include a bottom plate 23. The bottom plate 23 is fixedly disposed at the bottom 104 of the trench 101 by a fastener including, but not limited to, a bolt, etc., and the bottom plate 23 is simultaneously connected to the bottoms 104 of the two side plates 22.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above-described preferred embodiments should not be construed as limiting the invention, which is defined in the appended claims. It will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the spirit and scope of the invention, and such modifications and adaptations are intended to be comprehended within the scope of the invention.
