Therefore, the moving direction of the vertical rod 9 and the bearing plate 13 can be effectively limited by the sliding rod 18. A vertical groove 10 is longitudinally opened on the side wall of the vertical rod 9, and a second screw rod 11 is longitudinally rotatably connected in the vertical groove 10. A moving block 12 is threadedly sleeved on the rod wall of the second screw rod 11, and a bearing plate 13 is fixedly connected to the side wall of the moving block 12.

[0027] How it works

[0028] When the maintenance device for a bridge crane is used, when the bridge crane 3 needs to be repaired, the second motor 15 is first started to drive the second screw rod 11 fixedly connected to the end of its rotating shaft to rotate, and the second screw rod 11 drives the moving block 12 threadedly sleeved on the rod wall and the supporting plate 13 fixedly connected to the side wall of the moving block 12 to move downward until it is convenient for maintenance personnel to enter the top surface of the supporting plate 13. At this time, the fence 14 on the top surface of the supporting plate 13 can protect the maintenance personnel, and then the second motor 15 is started again to drive the second screw rod 11 to rotate, and the second screw rod 11 drives the moving block 12 threadedly sleeved on the rod wall and the supporting plate 13 fixedly connected to the side wall of the moving block 12 to move upward. Move until the maintenance personnel are driven to a suitable maintenance position, and then start the first motor 7 again, and the first motor 7 drives the first screw rod 8 fixedly connected to the end of its rotating shaft to rotate, and the first screw rod 8 drives the vertical rod 9 threaded on the rod wall and the load-bearing plate 13 installed on the vertical rod 9 to move horizontally, until the maintenance personnel are driven to the required maintenance position to facilitate the maintenance of the bridge crane 3. When the first screw rod 8 drives the maintenance personnel to move in parallel, at this time, thanks to the setting of the slide rod 18, the slide rod 18 and the first screw rod 8 both pass through the vertical rod 9, and the slide rod 18 is located above the first screw rod 8, so that the sliding rod 18 can effectively limit the moving direction of the vertical rod 9 and the load-bearing plate 13.
