The invention provides a crane hook rotation prevention mechanism, and relates to the technical field of crane hooks, the crane hook rotation prevention mechanism comprises a side plate and a connecting block, the connecting block is arranged below the inner side of the side plate, a hook assembly is rotatably arranged in the connecting block, a sleeve is arranged above the hook assembly, an insertion rod is movably inserted in the sleeve, and the insertion rod is movably inserted in the sleeve. A limiting rod is arranged at the front end of the inserting rod, the length of the limiting rod is matched with the distance between the inner sides of the side plates, a threaded rod is installed on the top of the sleeve in a threaded mode, and the threaded rod is driven by a driving part to rotate; the sleeve is fixed to the upper end of the lifting hook assembly, the insertion rod is inserted into the sleeve and fixed through the screw rod, and the length of the limiting rod at the front end of the insertion rod is matched with the distance between the inner sides of the side plates, so that the lifting hook assembly can be fixed, a driver is effectively prevented from rotating the hook type lifting hook assembly, and the working efficiency is improved; free rotation of the lifting hook assembly can be achieved only by loosening the screw rod and pulling out the insertion rod.

    本发明提供了一种行车吊钩防止转动的机构,涉及行车吊钩技术领域,包括侧板和连接块,所述连接块设在侧板内侧的下方,所述连接块的内部转动设有吊钩组件,所述吊钩组件的上方设有套筒,且套筒的内部活动插设有插杆,所述插杆的前端设有限位杆,且限位杆的长度与所述侧板的内侧间距相匹配,所述套筒的顶部螺纹安装有螺杆,且螺杆通过驱动部驱动旋转;本发明在吊钩组件上端固定一个套筒,插入插杆并通过螺杆固定,由于插杆前端的限位杆长度与侧板的内侧间距相匹配,即可固定吊钩组件,有效防止行车司机自己挂钩式吊钩组件转动,提升工作效率,且安装快捷,需要吊钩组件转动时,只需要松开螺杆,抽出插杆即可实现吊钩组件自由转动。
