The invention relates to the technical field of hoist cranes, in particular to a hoist crane hooking and unhooking hook which comprises a hoisting chain, a connecting seat is arranged at the bottom end of the hoisting chain, a hook is arranged at the bottom end of the connecting seat, a clamping assembly is arranged at the bottom end of the inner side of the hook, and the clamping assembly comprises a strip-shaped rubber block. The strip-shaped rubber block is located in the middle of the inner side of the hook, and an arc-shaped protruding strip is arranged on the surface of the top end of the strip-shaped rubber block. By designing the lifting chain, the connecting base, the hook and the clamping assembly, when the hook of the hoist crane is used for hanging a heavy object, after a steel wire rope connected with the heavy object is hooked on the inner side of the hook, the steel wire rope can be tightly fixed on the inner side of the hook under the interaction of all the components, and when the hoist crane is used for hoisting the heavy object, the steel wire rope can be tightly fixed on the inner side of the hook. The heavy object cannot shake due to displacement of the steel wire rope on the inner side of the hook, so that when the hoist crane hoists the heavy object, the stability is better, the safety is higher, the structure is novel, and the practicability is high.
本发明涉及起重葫芦技术领域,特别是涉及一种起重葫芦用挂脱钩,包括起重链条,所述起重链条底端设置有连接座,所述连接座底端设置有挂钩,所述挂钩内侧底端设置有夹紧组件,所述夹紧组件包括条形橡胶块,所述条形橡胶块处于挂钩内侧中部,所述条形橡胶块顶端表面设置有弧形凸条;通过设计了起重链条、连接座、挂钩、夹紧组件,使得起重葫芦的挂钩对重物进行悬吊时,连接重物的钢丝绳钩挂于挂钩内侧后,会通过各个部件之间的相互作用下,使得钢丝绳紧紧地被固定于挂钩内侧,当起重葫芦起吊重物时,重物不会因为钢丝绳在挂钩内侧发生位移而导致晃动,使得起重葫芦起吊重物时,稳定性更佳,安全性更高,结构新颖,实用性强。
