A safety hook capable of being automatically disassembled after a lifting steel wire rope is broken comprises a pulley and a hook head, and the pulley and the hook head are connected through a stable connecting assembly so that a heavy object can be kept stable when being lifted; the stable connecting assembly comprises a connecting frame and a balance beam, the connecting frame is connected with the pulley and the balance beam, and the balance beam is connected with the connecting frame and the lifting hook head; the connecting frame is connected with the pulley through a rotating shaft on the pulley connecting lug plate, a safety device is arranged at the joint of the connecting frame and the pulley, and the safety device triggers the safety hook to be disassembled when a rope breaking accident occurs; the safety lifting hook is disassembled, so that a lifting and hoisting mechanism on one side of the lifting equipment without rope breakage can be prevented from being damaged due to excessive overload, metal structures except the lifting hook head are prevented from being damaged due to serious unbalance loading, the caused damage and property loss are reduced, and the safety of the lifting equipment in the using process is also greatly improved.

    一种起升钢丝绳断绳后可自动解体的安全吊钩,包括滑轮与吊钩头,滑轮与吊钩头之间通过稳定连接组件连接,使重物吊起时保持平稳;稳定连接组件包括连接架与平衡梁,连接架连接滑轮与平衡梁,所述平衡梁连接连接架与吊钩头;所述连接架与滑轮经滑轮连接耳板上的旋转轴连接,连接架与滑轮连接处设置安全装置,安全装置在发生断绳事故时触发安全吊钩解体;安全吊钩解体可使起重设备未断绳一侧的起升卷扬机构避免过度超载而发生损坏,使除吊钩头以外的金属结构不会出现严重偏载发生损坏,减少了造成的损害和财产损失,也大幅提高了起重设备使用过程中的安全性。
