At this time, the slider link 7 and the double drive link 8 are in oblique line positions.
When the lifting wire rope 40 is broken, the tension of the lifting wire rope 40 disappears, and the cargo bed 35 rapidly drops. The relief spring 17 changes from a compressed state to an extended state. The anti-falling steel wire rope 11 is in a loose state, the pulling force of the anti-falling steel wire rope 11 on the hook part 91 of the winding spring 9 disappears, the winding spring 9 rotates to a second angle position under the action of elastic force to drive the dual-drive connecting rod 8 to rotate, the dual-drive connecting rod 8 drives the two slide block connecting rods 7, and the two slide block connecting rods 7 drive the corresponding movable teeth 1 to move towards the fixed teeth 39 until the movable teeth 1 are meshed with the fixed teeth 39.

The problem of load-carrying platform unbalance loading caused by the fracture of the unilateral lifting steel wire rope is solved. At the moment, the position of one of the slide block connecting rods 7 is locked through the locking assembly, and when the double-drive connecting rod 8 and the two slide block connecting rods 7 are on the same straight line, a dead point state is formed, so that the locking force is large, and the locking device is safe and reliable.
Specifically, the slider link 7 has a chamfer, and in the process of changing the slider link 7 from the oblique position to the linear position, the slider link 7 presses the roller 27, further presses the L-shaped locking hook 24 to rotate around the locking hook pin 29, further compresses the locking spring 25, and when the slider link 7 moves to the locking space k, the L-shaped locking hook 24 is reset under the action of the locking spring 25.
