The invention relates to the technical field of crane hanging elements, and discloses an anti-falling fixing device for a crane hook. The anti-falling fixing device comprises a hanging plate, a beam plate is fixedly connected into the hanging plate, a hook handle is fixedly connected to the right side of the beam plate, a hook body is movably connected to the lower portion of the hook handle, an anti-falling structure is movably connected into the hook handle, a long bolt is movably connected to the upper portion of the anti-falling structure, a limiting groove is formed in the beam plate, anda movable rod is arranged in the limiting groove in an inserted mode. According to the anti-falling fixing device for the crane hook, a movable groove, a movable block and a limiting pin are movablyconnected into the anti-falling structure, the position of a protrusion at the bottom end of the anti-falling structure on the hook body can be controlled according to a hung object through movement of the movable block and the limiting pin on the movable groove, and therefore the phenomena that the surface shakes greatly in the hanging process, as a result, materials are damaged, cost waste is caused can be avoided, use is convenient, and the cost is saved.
本发明涉及起重机吊挂元件技术领域,且公开了一种起重机吊钩的防脱落固定装置,包括吊板,所述吊板的内部固定连接有梁板,所述梁板的右侧固定连接有吊钩柄,所述吊钩柄的下方活动连接有吊钩主体,所述吊钩柄的内部活动连接有防脱落结构,所述防脱落结构的上方活动连接有长螺栓,所述梁板的内部开设有限位槽,所述限位槽的内部插接有活动杆。该起重机吊钩的防脱落固定装置,防脱落结构内部活动连接的活动槽、活动块以及限位销,通过活动块和限位销在活动槽上的移动可以根据悬挂的物体来控制防脱落结构底端的凸起在吊钩主体的位置,这样可以使表面在悬挂时造成很大晃荡,带来材料的损坏,造成成本浪费,使用便利,节约成本。
