The invention relates to the field of hoisting equipment, and discloses a lifting hook capable of being automatically disassembled after a lifting steel wire rope is broken, the lifting hook comprises a lifting hook body, a balance beam and two sets of connecting frames, the balance beam comprises two parallel beam plates, the lifting hook body is arranged in the middle between the two beam plates, and the two sets of connecting frames are arranged at the two ends between the two beam plates respectively; steel wire ropes are installed at the tops of the connecting frames, a horizontally-arranged pin shaft is arranged in each connecting frame, the two ends of each pin shaft are connected with the corresponding beam plate, anti-disengaging devices are arranged at the connecting positions of the pin shafts and the beam plates, and jacking parts extending out of the bottom of the balance beam are arranged at the bottoms of the connecting frames. When one steel wire rope is broken, the balance beam collides with the jacking part of the unbroken steel wire rope, the two beam plates are rapidly expanded outwards by the inclined surfaces, and the beam plates are separated from the pin shaft due to the fact that the expanding force borne by the beam plates is far larger than the anti-falling force applied to the beam plates and the pin shaft by the anti-falling device. Therefore, the beam plate and the pin shaft are disassembled.
本发明涉及起重设备领域,公开了一种起升钢丝绳断绳后可自动解体的吊钩,包括吊钩、平衡梁以及两组连接架,平衡梁包括两片相互平行的梁板,吊钩设置于两片梁板之间的中部,两组连接架分别设置于两片梁板之间的两端,连接架的顶部安装有钢丝绳,每组连接架中均设有一根水平设置的销轴,销轴的两端分别与一梁板相连接,销轴与梁板的连接位置均设有防脱装置,连接架的底部设有延伸出平衡梁底部的顶开部,顶开部的两侧分别设有延伸至对应梁板外侧且倾斜向下的斜面,当一钢丝绳断裂,平衡梁与未断裂钢丝绳的顶开部撞击,两片梁板被斜面快速向外撑开,因梁板所受到的撑开力度远大于防脱装置对梁板与销轴施加的防脱力度,从而使梁板与销轴之间解体。
