The second rail wheels 16 are rollingly connected to the rail 12 after the lifting device is operated. The direction in which the second rail wheels 16 are arranged is perpendicular to the direction in which the first rail wheels 15 are arranged. A second reducer motor 17 is arranged on one side of one of the second rail wheels 16. The second reducer motor 17 is power-connected to the second rail wheels 16. Elastic wheel assemblies are arranged on one side of the two second rail wheels 16 located on the vehicle body 13 away from the second reducer motor 17.

[0024] Advantageously, the elastic wheel assembly includes a bracket 21, which is fixedly arranged on one side of the first track wheel 15 and the second track wheel 16. A mounting frame 22 is provided on the lower side of the bracket 21, and a track roller 26 is provided between the mounting frames 22. An intermediate shaft 24 is provided to rotate inside the track roller 26, and the intermediate shaft 24 and the track roller 26 can be rotatably connected through a bearing. A card slot structure is provided in the mounting frame 22 for hingedly connecting the track roller 26 in the mounting frame 22, and an elastic structure is provided between the bracket 21 and the track roller 26 to play an elastic buffering role on the track roller 26.

[0026] Advantageously, the elastic structure includes connecting plates 27 arranged on both sides of the intermediate shaft 24, a guide rod 29 is provided on the upper side of the connecting plate 27, the guide rod 29 is fixed to one side of the bracket 21, a spring 28 is provided on the outer surface of the guide rod 29, the guide rod 29 slides through the connecting plate 27, and the spring 28 is elastically arranged between the connecting plate 27 and the bracket 21.

[0027] Advantageously, a limiting nut is further provided at the bottom of the connecting plate 27 , and the limiting nut is fixedly connected to the guide rod 29 by threaded engagement, so as to limit the position of the connecting plate 27 .

[0028] Advantageously, the lifting device includes a hydraulic cylinder 34 and a slide rod 33 arranged on the top of the second track wheel 16. The slide rod 33 slides through the top plate of the second track wheel 16 and is fixedly connected to the vehicle body 13. The push rod of the hydraulic cylinder 34 slides through the top plate of the second track wheel 16 and is fixedly connected to the vehicle body 13.

[0029] When the device is at the intersection of the rails 12, the distance between the first rail wheels 15 is set to meet the spacing of the rails 12 on the one hand, and on the other hand, the first rail wheels 15 need to be located between the other pair of rails 12, such as Figure 2As shown, similarly, in addition to meeting the spacing between the other pair of rails 12, the second rail wheel 16 also needs to be set on the outside of the rail 12, and when the equipment moves to the intersecting rail 12, the second rail wheel 16 and the elastic wheel assembly on one side of the first rail wheel 15 can cross the vertical part of the rail 12, so that the vehicle can be guided and moved along the vertical rail 12, so that the wheels of the first moving device or the second moving device of the vehicle are always guided against the rail to avoid derailment.

[0030] When the device is working, it moves along one of the pairs of rails 12. At this time, after the first reducer motor 11 works, the universal joint 14 is used to drive two of the first rail wheels 15 to rotate, thereby moving the device along the rail 12; when the device moves to one side of the other pair of vertical rails 12, the second rail wheel 16 needs to move to the upper side of the other pair of vertical rails 12, and then the push rod is pushed out of the hydraulic cylinder 34 after the hydraulic cylinder 34 works. However, since the push rod of the hydraulic cylinder 34 is fixed to the vehicle body 13, it is equivalent to moving the second rail wheel 16 away from the vehicle body 13. The slide rod 33 plays a guiding role, so that after the second rail wheel 16 is connected to the other pair of rails 12, it also synchronously drives the rail roller 26 in the elastic wheel assembly on one side to roll against the other pair of rails 12, thereby disconnecting the first rail wheel 15 from the rail 12 on one side. At this time, the second reducer motor 17 can drive the second rail wheel 16 to rotate after working, so that the device can be translated vertically along the other pair of rails 12.

[0031] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention; therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
