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] The following will be described by taking the spreader according to the embodiment of the present invention as the main spreader of the tower as an example, but the spreader according to the embodiment of the present invention is not limited thereto, it can also be applied to other hoisting devices according to the actual situation pieces.

[0040] Such as image 3 with Figure 4As shown, the spreader may include a lifting beam 31 , lifting lugs 32 and straps 34 . The cross section of suspension beam 31 is substantially circular, preferably circular, can be solid, also can be hollow, and two suspension lugs 32 are detachably mounted on suspension beam 31, to connect such as tower tube 40 (see Figure 10 ) etc. to be hoisted. A strap 34 ma...

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 of a wind power generating set. Background technique [0002] For the tower of the wind power generating set, at the assembly site, the tower is usually placed in a horizontal state. 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 spreader used by the main crane is called the main sling, and the spreader used by the auxiliary crane is called the auxiliary sling. The main sling and the auxiliary sling The tools are referred to as the main spreader and the auxiliary spreader respectively. The auxiliary spreader assists in the completion of the tower turning. After the t...
