The invention discloses a lifting hook safety bolt connecting pair in the technical field of building components. The lifting hook safety bolt connecting pair comprises a lifting hook body, fixing nuts, a limiting bolt and the like, the fixing nuts are symmetrically and fixedly connected to the side wall of the lifting hook body, and the limiting bolt is connected in the fixing nuts in a threadedmode. The limiting bolt is inserted in the fixing nuts, the limiting bolt and the fixing nuts are connected through threads and are relatively fixed in position, and therefore the limiting bolt and the lifting hook body form a closed semi-ring shape together, and a hooked object is limited in the lifting hook body. According to the lifting hook safety bolt connecting pair, in the threaded connection state of the limiting bolt and the fixing nuts, the closed semi-ring shape formed by the limiting bolt and the lifting hook body together does not comprise a weak connecting position, the potentialsafety hazard that the lifting hook safety bolt connecting pair is likely to be damaged is eliminated, and the reliability degree is greatly improved; and by screwing the limiting bolt out of the fixing nuts, the limiting bolt and the fixing nuts are separated, and closing of the limiting bolt for a lifting hook is relieved. Compared with an existing safety buckle opening mode, the operation of taking out the hooked object is also more convenient.
本发明公开了建筑构件技术领域中吊钩保险螺栓连接副,包括吊钩本体、固定螺母和限位螺栓等,吊钩本体的侧壁上对称固定连接有固定螺母,固定螺母内螺纹连接有限位螺栓,通过将限位螺栓插入固定螺母内,两者通过螺纹连接位置相对固定,由此限位螺栓与吊钩本体共同组成封闭的半环状,从而将钩掉物限位于吊钩本体内,本发明吊钩保险螺栓连接副中限位螺栓与固定螺母螺纹连接状态下,限位螺栓与吊钩本体共同组成封闭的半环状没有薄弱连接处,消除了易损坏的安全隐患,可靠程度大大增加,且通过将限位螺栓旋出固定螺母,使二者分离而打开限位螺栓对吊钩的封闭,去取出钩掉物的操作与现有安全扣的打开方式相比同样较为方便。
