The invention belongs to the technical field of crane hooks, and particularly provides a hook assembly and a lifting appliance. The lifting hook assembly comprises a lifting hook mounting seat and a self-unhooking lifting hook rotationally mounted on the lifting hook mounting seat, the lifting hook is provided with a closing position/unhooking position connected with/separated from a lifted object, a spring lock is arranged on the lifting hook mounting seat, and a stopping part used for being matched with a spring bolt of the spring lock to limit the lifting hook at the closing position is arranged on the lifting hook. The spring lock is further provided with an unlocking mechanism. The lifting appliance comprises the lifting hook assembly. Under the action of the spring lock, the lifting hook can be stably kept at the closed position, the situation that the lifting hook is accidentally separated from a lifted object is avoided, after lifting is completed, the spring lock is manually unlocked, the lifting hook can return to the unhooking position, and operation of workers is facilitated. And meanwhile, the lifting hook rotates along a fixed shaft, the gravity of a lifted object mainly acts on the lifting hook mounting seat, and the lifting hook has longer service life naturally.
本发明属于起重机吊钩技术领域,具体提供一种吊钩组件及起吊吊具。该吊钩组件包括吊钩安装座以及转动安装在吊钩安装座上的自脱钩式的吊钩,吊钩具有与起吊对象连接/脱离的封闭位/脱钩位,吊钩安装座上设有碰锁,吊钩上设有用于与碰锁的锁舌配合以将吊钩限制在封闭位的挡止部,碰锁还配置有解锁机构。该起吊吊具包括上述吊钩组件。本发明在碰锁的作用下,吊钩可以稳定保持在封闭位,避免吊钩意外和起吊对象分离,起吊完成后,手动对碰锁解锁,吊钩可以回复到脱钩位,方便工作人员操作。同时,吊钩定轴转动,起吊对象的重力主要作用在吊钩安装座上,自然也就具有更长的使用寿命。
