Embodiment Construction

[0038] Embodiments according to the present invention will now be described in detail with reference to the accompanying drawings, examples of which are shown, in which like reference numerals refer to like components throughout.

[0039] First, the structure of a tower spreader according to an exemplary embodiment of the present invention will be described with reference to the drawings. refer to Figure 1 to Figure 5 , the tower spreader according to the exemplary embodiment of the present invention includes a hanger 3 , a fixing frame 10 , at least two clamping arms 17 and a locking structure 5 . Wherein, the fixing frame 10 is located under the hanging base 3 , and the locking structure 5 can lock the hanging base 3 to the fixing bracket 10 or unlock it from the fixing bracket 10 . When using the tower spreader to perform hoisting operations, the hook 1 and the strap 2 can be connected to the hanger 3, in other words, the hanger 3 can provide a lifting point.

Abstract

The invention provides a tower drum lifting appliance. The tower drum lifting appliance comprises a lifting seat, a fixing frame, at least two clamping arms and a locking structure, wherein the fixingframe is located below the lifting seat; at least two clamping arms are hinged to the hanging seat and the fixing frame in a radial mode according to a preset angle interval, so that the clamping arms can move relative to the fixing frame to clamp or loosen the flange of a tower drum; and the locking structure can lock the lifting seat to the fixing frame or unlock the fixing frame. According tothe tower drum lifting appliance, the tower drum lifting appliance can be locked and unlocked, vertical hoisting of tower drums with various diameters can be met, the production cost is saved, and thehoisting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a tower hanger used for hoisting a tower of a wind power generating set. Background technique [0002] The existing spreader used for hoisting the tower is generally a four-lug type spreader and is connected to the flange of the tower by bolts. Each lifting lug is designed according to the load, and the number of bolts required is related to the weight of the tower. , and the larger the diameter of the tower, the more bolts are required, and the longer it takes to install the lifting lugs. [0003] In addition, for towers with different diameters, the lug bolt holes need to be customized. For example, the diameter of the tower of 2MW, 3MW, 6MW, 8MW, 10MW and other wind turbines gradually increases, and the diameter of the tower and the bolt index circle are different. , so that the lifting lugs cannot be used universally. Therefore, the lifting lugs need to be desi...
