The invention discloses a lifting hook rotary positioning device, and belongs to the technical field of lifting hooks. The lifting hook rotary positioning device comprises a suspension frame, a locking block is fixedly connected to the interior of the suspension frame, a lifting hook rod is inserted into the locking block, extendable check blocks are arranged on the two sides of the lifting hook rod correspondingly, cavities are formed in the two sides of the interior of the locking block correspondingly, the extendable check blocks are clamped into the cavities, the outer surface of the lifting hook rod is sleeved with a lifting frame, and sliding grooves are formed in the two sides of the interior of the suspension frame. According to the lifting hook rotary positioning device, through cooperative use of the suspension frame, the lifting hook rod, the locking block, the extendable check blocks, a gear and a push rod, when materials are lifted, the lifting hook rod descends under the influence of gravity, the extendable check blocks are clamped in the locking block, therefore the lifting hook rod is clamped in the locking block, the lifting hook rod is prevented from rotating in the air under the influence of the materials, and potential safety hazards are prevented from occurring.
本发明公开了一种吊钩旋转定位装置,属于吊钩技术领域。一种吊钩旋转定位装置,包括悬吊架,所述悬吊架的内部固定连接有锁紧块,所述锁紧块的内部插接有吊钩钩杆,所述吊钩钩杆的两侧均设置有伸缩挡块,所述锁紧块内部的两侧均开设有空腔,所述伸缩挡块卡接在空腔的内部,所述吊钩钩杆的外表面套接有升降架,所述悬吊架内部的两侧均开设有滑槽;本发明通过悬吊架、吊钩钩杆、锁紧块、伸缩挡块、齿轮和推动杆的配合使用,当将物料吊起时,吊钩钩杆受到重力的影响会进行下降,伸缩挡块会卡在锁紧块内,从而使吊钩钩杆卡在锁紧块内,避免吊钩钩杆受到物料的影响在空中进行旋转,防止安全隐患的发生。
