[0029] In the specific embodiment of the utility model, the two movable ends of the two anti-drop plates 3 are in the upward state in the initial state, which does not hinder the butt joint of the lifting hook body 1 and the goods. When the goods are lifted on the lifting hook body 1, the synchronous driving assembly is controlled to drive the two transmission worms 8 to rotate synchronously, so that the two transmission worms 8 drive the two transmission worms 7 to rotate synchronously, the two transmission worms 7 drive the two anti-drop plates 3 to rotate downward, the hook opening of the lifting hook body 1 is closed, the goods are prevented from falling off during lifting, the safety of the lifting operation is greatly improved, the controllability of the anti-drop function is realized through the accurate and rapid control of the anti-drop plate 3, the anti-drop function of the lifting hook body 1 is ensured at any time, or the anti-drop function is cancelled, manual unlocking of the anti-drop function of the lifting hook body 1 is not needed, the unloading efficiency is improved, and the flexibility is high.
[0030] Specifically, the synchronous driving assembly comprises the synchronous box 5 and two synchronous wheels, the synchronous box 5 is fixedly connected to one side of the inclined outer surface of the lifting hook body 1, the two synchronous wheels are rotatably connected between the inner walls of the two sides of the synchronous box 5, and the two synchronous wheels are fixedly connected with the two transmission worms 8.
[0031] In this embodiment, the two synchronous pulleys are connected by a synchronous belt drive, and the two synchronous pulleys drive the two transmission worm gears 8 to rotate synchronously.
[0032] Specifically, the synchronous drive assembly also includes a drive motor 6, which is fixedly mounted on one side of the outer surface of the synchronous box 5, and the output end of the drive motor 6 is fixedly connected to one of the synchronous pulleys.
[0033] In this embodiment, the drive motor 6 is started by controlling it to drive the corresponding synchronous wheel to rotate, thereby driving the two synchronous wheels to rotate synchronously.
