[0035] Working principle:

[0036] The sliding guide rail 1 is positioned and installed on both sides inside the platform of the subway maintenance station, allowing the bearing support plate 3 to be aligned and assembled with the alignment sliding groove 2 via the sliding connecting block 4. With the support of the sliding structure between the sliding connecting block 4 and the alignment sliding groove 2, the bearing support plate 3 and its upper part have a directional sliding effect. By pulling the sliding auxiliary handle 6, the bearing support plate 3 and its upper part are slidably pulled to the designated corresponding maintenance position under the action of the sliding structure. External braking components can be installed to position and secure the sliding displacement of the bearing support plate 3. Maintenance personnel can climb to the maintenance bearing plate 9 via the first-level climbing ladder 10, the second-level climbing ladder 11, and the third-level climbing ladder 12. The distance between the maintenance bearing plate 9 and the bottom of the subway vehicle to be inspected is controlled by the lifting control switch 15. The electric telescopic rod 7 is adjusted for appropriate lifting and lowering. The telescopic support guide rod 8 assists in the entire lifting and lowering operation while ensuring the stability and smoothness of the maintenance support plate 9 during the lifting and lowering process. Maintenance personnel can place maintenance tools stably in the tool placement slot 14 and lie flat in the flat maintenance slot 13 to inspect and maintain the bottom of the subway car to be maintained. The sliding telescopic structure of the first-level climbing frame 10, the second-level climbing frame 11, and the third-level climbing frame 12 allows the lifting device to carry out normal subway car maintenance work in any lifting and lowering state of the maintenance support plate 9. The lifting and lowering adjustment of the maintenance support plate 9 will not affect the maintenance personnel's climbing to the maintenance support plate 9 for maintenance work, effectively ensuring the high stability and smoothness of the overall normal use and extending the overall service life accordingly.
