The invention relates to a universal turnover lifting appliance for a fragmented tower. A lifting seat is vertically fixed on a weight box, the weight box, a small gear shaft and a large gear shaft are parallel to one another, the small gear shaft and the large gear shaft sequentially penetrate through the lifting seat from bottom to top, a speed reducer and a motor are fixed on the weight box, the motor and the speed reducer are arranged at one end of the small gear shaft and drive the small gear shaft to rotate, and a small gear is arranged close to the other end of the gear shaft. A large gear is arranged close to the other end of the large gear shaft, the small gear is engaged with the large gear, a large bearing seat is fixed to the position, close to one end of the large gear, of the lifting seat, a large bearing is arranged between the large bearing seat and the large gear shaft, a locking nut is fixed at one end of the large gear shaft, a large inner ring is fixed between the locking nut and the inner ring of the large bearing, a large outer ring is arranged on the outer side of the large inner ring in a sleeving manner, is blocked on the outer ring of the large bearing and is fixed on the large bearing seat, and the other end of the large gear shaft is fixed on a fixed plate parallel to the lifting seat through multiple bolts. By means of the lifting appliance, the lifting appliance replacement time is shortened, and the working efficiency is improved.
