A lifting ring is arranged in the center of the upper surface of a lifting hook base, hinge seats are evenly distributed on the outer side face of the lifting hook base, a lifting hook is hinged to each hinge seat, a long sliding hole is formed in the middle of a long rod body of each lifting hook, and a supporting sliding rod is coaxially arranged in the middle of the bottom face of the lifting hook base. A circular ring body of the limiting piece coaxially sleeves the supporting sliding rod in a sliding manner, U-shaped seats are uniformly distributed on the outer side of the circular ring body, transverse rods which are correspondingly and transversely connected in the long sliding holes in a sliding manner are arranged at the outer ends of the U-shaped seats, and a limiting adjusting mechanism is arranged between the sliding rod and the circular ring body; the lifting hooks of the lifting appliance can move up and down along the supporting sliding rod to adjust the opening amplitude of the lifting hooks, the hook bodies on the lower portions of the lifting hooks can be inserted into the screw holes by adjusting the opening amplitude of the lifting hooks, and the lifting hooks are locked through the limiting adjusting mechanism. The steel ring can be kept in a stable state during hoisting in a mode that the uniformly distributed lifting hooks are simultaneously stressed and hoisted, the phenomenon that the steel ring slips due to the unstable gravity center of the steel ring is avoided, the operation is relatively convenient, and the safety is relatively high.
一种用于金刚石压机钢环的内撑平衡吊具,其吊钩基座的上表面中心设有吊环,外侧面均布有铰接座,每个铰接座上均铰接有一根吊钩,吊钩的长杆体中部设有长滑孔,吊钩基座的底面中部同轴设有支撑滑杆,限位件的圆环体同轴滑动套装在支撑滑杆上,圆环体的外侧均布有U形座,U形座外端设有对应横向滑动连接在长滑孔内的横杆,在滑杆和圆环体之间设有限位调节机构;该吊具的吊钩可沿着支撑滑杆上下移动来调整吊钩的张开幅度,通过调整吊钩的张开幅度可使其下部的钩体插入到螺丝孔内,并通过限位调节机构将各个吊钩锁定,这种均布的吊钩同时受力吊装的方式可保持钢环的吊装时处于平稳状态,避免由于其重心不稳滑脱的现象,操作比较方便,安全性较高。
