Embodiment Construction

[0038] Now, embodiments according to the present invention will be described in detail with reference to the accompanying drawings, examples of which are shown in the accompanying drawings, in which the same reference numerals always denote the same components.

[0039] Hereinafter, the spreader according to the embodiment of the present invention will be used as the main spreader of the tower as an example for description, but the spreader according to the embodiment of the present invention is not limited to this, and it can also be applied to other hoisting devices according to actual conditions. Pieces.

[0040] Such as image 3 with Figure 4 As shown, the spreader may include a lifting beam 31, lifting lugs 32, and a lifting strap 34. The cross section of the hanging beam 31 is approximately circular, preferably circular, and can be solid or hollow. Two lifting lugs 32 are detachably installed on the hanging beam 31 to connect such as the tower 40 (see Picture 10 ) Waiting t...

Abstract

The invention provides a lifting appliance. The lifting appliance comprises a lifting beam, lifting lugs, lifting rings and lifting belts, wherein the at least two lifting lugs are detachably installed on the lifting beam to connect a piece to be lifted; the lifting rings rotationally sleeve the lifting beam and are arranged in the accommodating spaces of the lifting lugs, and the lifting lugs canbe abutted against the lifting rings and prevent the lifting rings from moving in the length direction of the lifting beam; and the lifting belts are connected to the lifting rings. According to thelifting appliance provided by the invention, through the arrangement for the lifting beam, the flange of a tower barrel can be prevented from being deformed due to the effect of a radial component force in a lifting process to influence assembly for the tower barrel.

Description

Technical field [0001] The invention relates to the technical field of wind power generation, in particular to a hoisting tool for hoisting a tower tube of a wind power generating set. Background technique [0002] For the tower of a wind turbine, the tower is usually placed horizontally at the assembly site. Due to the long length of the tower and the requirements of the hoisting process, during the hoisting process, the tower needs to be turned 90 degrees to a vertical state before hoisting and assembly. [0003] At present, the cranes used for hoisting towers are divided into main cranes and auxiliary cranes. The slings used by the main cranes are called the main slings, the slings used by the auxiliary cranes are called the auxiliary slings, the main slings and the auxiliary slings The tools are referred to as the main spreader and auxiliary spreader respectively. The auxiliary spreader assists in completing the turning of the tower tube. After the turnover is completed, the ...
