The invention provides a lifting hook capable of conveniently and rapidly lifting a column beam and being quickly disassembled. The hook comprises a right-angled n-shaped frame, wherein a lifting holeis formed in the position, close to the middle, of the outer surface of the front end of the right-angled n-shaped frame, clamping pieces are fixedly arranged at the positions, close to the two sidesof the lower end, of the outer surface of the front end of the right-angled n-shaped frame, a baffle is movably connected between the two clamping pieces, round holes are formed in the two ends of the outer surface of the rear end of the baffle, a pin is connected between each of the two round holes and the corresponding one of the two clamping pieces, a triangular bracket is fixedly arranged onthe outer surface of the rear end of the right-angled n-shaped frame, a long groove is formed in the position, close to the lower end, of the interior of the triangular bracket, and cylindrical barrels are movably connected to the positions, close to the front and rear ends, of the interior of the long groove. According to the hook, not only the problem that due to unbalanced lifting, a heavy lifting frame is blocked, and thus hook disassembly is inconvenient can be avoided, but also the problem of inconvenient operation caused by the large dead weight of the heavy lifting frame can be prevented.
本发明提供了一种可以便捷吊装柱梁并快速卸钩的吊钩,包括门形框,所述门形框的前端外表面靠近中间的位置开设有吊装孔,所述门形框的前端外表面靠近下端两侧的位置均固定安装有夹片,两个所述夹片之间活动连接有挡板,所述挡板的后端外表面两端的位置均开设有圆孔,两个所述圆孔与两个夹片之间均贯穿连接有销轴,所述门形框的后端外表面固定安装有三角支架,且三角支架的内部靠近下端位置开设有长槽,所述长槽的内部靠近前后端的位置均活动连接有圆筒。本发明,既能够避免因吊装不平衡时所导致重型吊框被卡住,导致脱钩不方便的问题,也可防止重型吊框本身自重较大而导致操作不便的问题。
