The invention provides a multipurpose large-diameter pipe joint lifting appliance capable of being used for lifting and turning over, and belongs to the technical field of lifting of precast concretecomponents. The multipurpose large-diameter pipe joint lifting appliance capable of being used for lifting and turning over comprises a main beam, a main lifting lug and a turning-over lifting hook; the main beam comprises a main cross beam, an upper lifting lug, lower lifting lugs and a connecting ring; the upper lifting lug is fixedly installed in the middle of the upper portion of the main cross beam, the two lower lifting lugs are fixedly arranged on the two sides of the bottom of the main cross beam respectively, and the connecting ring is fixedly connected to the front face of the main cross beam. According to the multipurpose large-diameter pipe joint lifting appliance capable of being used for lifting and turning over, after a pipe joint is turned over and moved to a turning-over area, the pipe joint is lifted to the position 1.8m-2 m away from the ground at the bottom, a main lifting hook of a gantry crane stops moving, when the pipe joint is stable and does not shake any more, the bottom of the pipe joint is hooked by a special-shaped hook in the turning-over lifting hook, and a small hook of the gantry crane is slowly lifted to pull a second steel wire rope till the pipejoint is horizontally placed. The lifting appliance is simple to install, and can stably lift the turnover pipe joint.

    本发明提供了一种可用于吊运翻身的多用大直径管节吊具,属于混凝土预制构件吊装技术领域。该可用于吊运翻身的多用大直径管节吊具包括主梁、主吊耳和翻身吊钩。所述主梁包括主横梁、上部吊耳、下部吊耳和连接环,所述上部吊耳固定安装于所述主横梁上方中部,所述下部吊耳设置有两组,且两组所述下部吊耳分别固定设置于所述主横梁底部两侧,所述连接环固定连接于所述主横梁正面。本发明管节翻身在管节移动至翻身区后,提升管节至底部离地1.8~2m,龙门吊主吊钩停止移动,待管节稳定不再晃动时,用翻身吊钩中的异型钩挂住管节底部,缓慢提升龙门吊小钩拉动第二钢丝绳,直至管节平放。本吊具安装简单,能够实现平稳吊装翻转管节。
