The invention discloses a heavy pipe hoisting device. The heavy pipe hoisting device comprises a hosting platform, and a support frame and a telescopic clamp both vertically fixed on the upper end surface of the hosting platform; the telescopic clamp comprises an outer threaded pipe vertically assembled on the support frame, and an inner threaded rod arranged inside the outer threaded pipe; a position regulation hand wheel is fixedly arranged on one end of the outer threaded pipe, and the other end of the outer threaded pipe is provided with a stretching slanting rod through a hinged shaft; a locking hand wheel for driving the inner threaded rod to rotate is fixedly arranged at the end of the regulation hand wheel, and a stretching blocking disc is arranged at the end of the stretching slanting rod; a hoisting rope is fixedly arranged on the hoisting platform; and the upper end surface of the hoisting platform is provided with a support block. According to the hoisting device adopting the technical scheme, firstly, the support block is chosen to enable the central axis of a heavy pipe to be on the central axis of the telescopic clamp, the regulation hand wheel is rotated to enable the telescopic clamp to stretching into the heavy pipe, then, the locking hand wheel is rotated for achieving movement of the stretching blocking disc, and the stretching slanting rod is unfolded and tightly holds the inner wall of the heavy pipe, as a result, location of the heavy pipe is finished, and then, the heavy pipe hoisting device is hoisted through the rope assembled on a hoist so as to realize hoisting.
