The present structure can be mechanically and automatically controlled, and the detection is stable and durable. The present structure can automatically control the locking when the traction pressure is lost. The principle of automatic control is that the rope connecting shaft 601 and the lifting adapter rod 201 lose the downward pressure of their own weight after the rope body 602 is broken. At the same time, the lifting control rod 604 adopted in the present structure is provided with a slide groove on the inner side of the slide groove, which does not affect the normal traction and movement of the rope connecting shaft 601 inside it.

[0044] The working principle of this embodiment is as follows: first, a hook is installed on the hook connection plate 303, and two lifting guide rods 101 and a pressurized stabilizing rod 102 are respectively installed on the gantry of the crane, and the rope body 602 is connected to the winch on the crane. The cargo is hoisted on the hook on the hook connection plate 303. When the cargo is manually hung, the worker rotates and presses the screw rod 305 to drive the pressing plate 307 on the adapter ball head 306 to press down to fit the cargo. When the rope body 602 is reeled in by the winch on the crane, the cargo is pulled. At this time, the lifting adapter The supporting rod 201 is lifted together, and the downward force is generated by its own weight and the counterweight of the counterweight block 202, which helps to improve the stability of the moving block 301 and makes the rope body 602 not easy to tilt. At the same time, when the transportation needs to be stopped urgently in an environment with strong winds, the downward pressure cylinder 203 can be used to drive the propelling ball head column 204 to move and insert it into the inclined groove on the pressurized stabilizing rod 102. By utilizing the characteristics of the inclined groove, when the propelling ball head column 204 presses against the inclined surface of the inclined groove on the pressurized stabilizing rod 102, it will be squeezed by the inclined groove, driving the lifting adapter rod 201 to produce The downward pressure is generated, and the stable moving block 301 is pressed down again. Under the action of wind force, or when the goods are moved by the crane moving component, it is easy to cause the rope body 602 to tilt and deviate. At this time, the touch column 505 on one side is squeezed, and the squeezing control micro switch 504 is energized, so that the driving motor 401 on the same side drives the driving compensation wheel 402 set to drive the moving block 301 to move, resist the shaking and displacement of the rope body 602 caused by wind force or the movement of the crane moving component, and realize compensation. The driving direction is driven by the driving motor 401. The movable block 301 moves in the opposite direction of the wind direction; after the rope body 602 breaks, the lifting adapter rod 201 and the stable moving block 301 will lose traction at the same time and fall freely. At this time, under the squeezing of the compression spring 603, the rope connecting shaft 601 will drive the lifting control rod 604 and the inclined plane control block 6041 to move downward, releasing the limit of the inclined plane control block 6041 on the limit head 702. At this time, under the pulling of the return tension spring 704, the limit head 702 can be inserted and positioned in the limit inclined block 1011 for locking, thereby realizing the protective locking work.
