Detailed Description

The invention is further described with reference to the accompanying drawings and the detailed description.

In the embodiment shown in fig. 1, 2 and 3, a rotary lifting hook includes a pulley 1, a cavity 2 is disposed at a lower end of the pulley 1, a rotating shaft 3 and a motor 4 are disposed in the cavity 2, a boss 5 is disposed on the rotating shaft 3, a bearing 6 and a driven gear 7 are disposed on the rotating shaft 3, the boss 5 is disposed on the bearing 6, the bearing 6 is fixedly connected with the cavity 2, the driven gear 7 is fixedly connected with the rotating shaft 3, a driving gear 8 is disposed on the motor 4, the motor 4 is fixedly connected with the driving gear 8, the driving gear 8 is connected with the driven gear 7 in a matching manner, a lifting hook 9 is disposed after the lower end of the rotating shaft 3 passes through the cavity 2, and the lifting hook 9 is. The upper end of pivot 3 is equipped with spring fixing base 10 and spring 11, and spring 11 cup joints with pivot 3, and spring 11's one end is connected with bearing 6, and spring 11's the other end is connected with spring fixing base 10.
