[0046] The working principle of a subway vehicle maintenance lifting device provided by the utility model is as follows:

[0047] The first step: the current lifting device can usually only inspect and repair one side and the top of the vehicle body. When the surface of the other side of the vehicle body needs to be repaired, the device can only be moved to the other side, which is more troublesome. In this device, a top platform 12 is set on the top of the vehicle body, and lifting components 3 are added on both sides of the top platform 12. When using it, the user can walk on the top platform 12 and move to the lifting platform 9 on the other side of the vehicle body. The structural design facilitates the work of the workers. At the same time, the first guide groove 13 and the second guide groove 21 are respectively set on the top platform 12 and the lifting platform 9. When the workers go to the side for maintenance, they can easily move the tool rack 17 carrying various tools to the lifting platform 9 on any side. Secondly, the structure also adds a steerable lighting component on the fences 10 on both sides, so that the staff does not need to manually turn on the lighting lamp 24 to operate, and the design is more humane;

[0048] The second step: when repairing some equipment on the top of the vehicle body, it is sometimes inconvenient to repair from the front, and the line of sight is easily blocked by objects, which is not conducive to checking and disassembling bolts. The current lifting device is not convenient for workers to move to the designated position on the side of the maintenance point for operation. Therefore, the device adds a boss 14 that can slide back and forth at the edge of the top platform 12. The boss 14 is plugged into the limiting hole 16 inside the limiting groove 11 through the limiting pin 19. The user first fixes the boss 14 through the limiting pin 19, and then can stand on the boss 14 to operate. Since the boss 14 is located on the upper side of the vehicle body and is very short from the roof, although the edge of the boss 14 is open, there is no need to worry about workers accidentally falling from it and getting injured.
