The invention relates to the technical field of cranes, and discloses a crane hook anti-disengaging protection device. The crane hook anti-disengaging protection device comprises a pulley disc, wherein the front side of the pulley disc is fixedly connected with a connecting plate, the surface of the connecting plate is fixedly connected with a display, a hook is arranged at the bottom of the connecting plate, a pressure sensor is arranged at the top of an internal crossbeam, a screw hole is formed in the right side of the crossbeam, the screw hole is internally and fixedly connected with a steel wire rope, the right end of the steel wire rope is fixedly connected with an auxiliary hook, and a rope outlet hole and a connection block hole are formed in the surface of an accessory box. According to the crane hook anti-disengaging protection device, through the cooperative use of the pressure sensor and the display, the weight of a lifting object and the force of gravity that the left endand the right end bear can be clearly obtained, and in comparison with the maximum mechanical value, whether the lifting object can be lifted or not can be seen; and the force is applied on the pressure sensor, the rotating shaft enables a safety hook to be in a closed state, the auxiliary hook is additionally installed at the end where the greater stress is shown by the display, so that the lifting object is prevented from slipping due to the unstable center of gravity in the lifting process.
本发明涉及起重机技术领域,且公开了一种起重机吊钩防脱保护装置,包括滑轮盘,滑轮盘的正面固定连接有连接板,连接板的表面固定连接有显示器,连接板的底部有吊钩,内部横梁的顶部有压力传感器,横梁的右侧开设有螺丝孔,螺丝孔内部固定连接有钢丝绳,钢丝绳的右端固定连接有辅助吊钩,附件箱的表面开设有出绳孔和连接块孔。该起重机吊钩防脱保护装置,通过压力传感器和显示器的配合使用,可以清晰地得到吊物的重量和左右端承受重力,可与机械最大值比较,看是否可吊起,压力传感器上有力,转轴就会使安全钩处于闭合状态,在显示器显示受力较大一端加装一个辅助吊钩,可防止上升过程中重心不稳,吊物滑落。
