Embodiment Construction

[0030] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0031] First of all, for a better understanding of the present invention, refer to figure 1 Briefly introduce the structure of the tower. The tower is generally composed of multiple tower sections. Each tower section includes a cylinder 100 and tower flanges 200 located at both axial ends of the cylinder. The tower flange 200 includes a transverse flange. The plate 201 and the vertical connecting plate are provided with a plurality of bolt mounting holes at intervals on the horizontal flange plate 201, and the vertical connecting plate is welded and fixedly connected with the cylinder body. The tower structure belongs to the prior art, so there will be no more repeat.

[0032] The specific embodiment of the wind power tower flange parameter control auxiliary tooling provided by the present invention is as follows: Figure 1 to Figure 6 As shown, the au...

Abstract

The invention relates to an auxiliary control tool for parameters of a wind power tower drum flange. The auxiliary control tool comprises a fixing base used for being fixed to a tower drum body, and a connecting structure used for being fixedly connected with a transverse flange plate of the tower drum flange. An elastic force applying structure is arranged between the connecting structure and the fixing base, and applies the elastic acting force with the set amplitude to the transverse flange plate in the axial direction of the tower drum body through the connecting structure. When part of planeness of the tower drum flange is out of tolerance, the elastic acting force applied to the transverse flange plate in advance through the elastic force applying structure is adjusted, so that in the subsequent welding or heat correcting process, the elastic acting force is released to make the transverse flange plate correspondingly corrected and adjusted when the transverse flange plate bears the elastic acting force, and out of tolerance of a local plane is eliminated.

Description

technical field [0001] The invention relates to an auxiliary tool for controlling flange parameters of a wind power tower tube. Background technique [0002] The tower of the wind turbine is used to support the wind turbine. As an important structure of wind power equipment, the tower must have high stability. Since the tower is a slender structure, it is prone to buckling instability. Therefore, the buckling resistance is very important for the safety and stability of the tower. The entire wind power tower is usually divided into three to four sections, and two adjacent sections are usually connected by flanges and high-strength bolts. This flange connection can effectively enhance the buckling resistance of the tower. [0003] Each tower section includes a cylinder and an L-shaped flange that is fixed and assembled at the corresponding end of the cylinder by welding. The L-shaped flange extends along the circumference of the cylinder as a whole, and the L-shaped flange in...
