The invention discloses a gravity self-locking type lifting hook anti-disengaging device in the technical field of lifting hook disengaging prevention. The gravity self-locking type lifting hook anti-disengaging device comprises a hook body; an upper slot is formed in the left side wall of the top of the hook body, a lower slot is formed in the lower wall of a hook opening of the hook body, a pushblock contraction cavity is arranged on the left side wall of the lower slot, a push block slide rod is connected to the left wall of an inner cavity of the push block contraction cavity, a push block spring sleeves a rod body of the push block slide rod, and a push block is arranged at the right end of the push block spring; self-locking of a button tooth and the hook body is realized through mechanical matching of the push block, a stop block and a loose pin, the risk of disengaging a lifted object from the hook body is avoided, the button tooth adopts vertical lifting type locking, the space in the inner cavity of the hook body is avoided from being occupied, the hooking and the unloading of the lifted object are avoided being hindered, the time consumed by hooking and unloading the lifted object is shortened, and man power is saved.
本发明公开了起吊钩防脱技术领域的一种重力自锁式起吊钩防脱钩装置,包括钩体,所述钩体的顶部左侧壁设有上插槽,所述钩体的钩口下壁开设有下插槽,所述下插槽的左侧壁开设有推块收缩腔,所述推块收缩腔的内腔左壁连接有推块滑杆,所述推块滑杆的杆体套接有推块弹簧,所述推块弹簧的右端设置有推块,通过推块、挡块和活销的机械配合,实现了扣牙和钩体的自锁,避免了被起吊物体从钩体脱钩的风险,扣牙采用垂直升降式锁合,避免了对钩体内腔空间的占用,从而避免妨碍被吊物体的钩挂和卸取,进而缩短了被吊物体的钩挂和卸取的耗时,节省了人力。
