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.
