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.
Description
technical field [0001] The invention relates to a sling, in particular to a split-type universal turning sling. Background technique [0002] In the prior art, the tower is an important infrastructure for wind power construction. With the development of wind turbines, in order to obtain more wind resources, the height of the center of the hub is particularly important, which in turn makes the height of the tower continue to increase. In order to ensure the safety factor of the tower, the body of the tower is getting bigger and bigger. Now there is a new type of segmented tower, which is to disassemble the segmented tower into several splits, and each piece is connected by bolts. It only needs to transport the fragmented towers to the site and then combine them into a whole, which solves the problems of large volume, heavy weight and difficult transportation of traditional towers. During the assembly process, the segmented tower needs to be turned over and aligned. At pre...
