One side of the slide plate is fixedly connected to one side of the tooth plate 24, and universal wheels 29 are fixedly connected to the four corners of the bottom of the bottom plate 1. Most of the current lifting devices are fixed and inconvenient to move, resulting in lifting only in a specific direction or position, and cannot cope with the lifting requirements of different angles and positions that may occur during the assembly of the rail train traction hook, affecting work efficiency and accuracy. By setting the universal wheel 29, it can be freely moved in multiple directions, providing greater flexibility.

[0040] Then the user starts the transmission motor 7 through the controller, the transmission motor 7 drives the first threaded rod 8 to rotate, the first threaded rod 8 drives the first threaded sleeve 18 to move, the first threaded sleeve 18 drives the movable plate 19 to descend, the movable plate 19 drives the connecting plate 20 to descend, and the connecting plate 20 drives the limit plate 9 to descend, so that the limit plate 9 contacts the top of the train traction hook, thereby limiting it and preventing swinging caused by external factors, thereby improving the safety and accuracy of the lifting operation.

[0041] At the same time, the movable plate 19 can also drive the toothed plate 24 to descend. When the toothed plate 24 descends, it will drive the gear 23 to rotate. The gear 23 drives the second threaded rod 12 to rotate. The second threaded rod 12 drives the second threaded sleeve 21 to move. The second threaded sleeve 21 drives the push plate 22 to move. The push plate 22 drives the fixed plate 13 to move, so that the fixed plate 13 moves to the fixed groove 27 inside the vertical plate 10, so as to further limit the lifting device to prevent displacement or sudden decline during the lifting process, thereby ensuring the safety and accuracy of the lifting operation.
