Problems solved by technology

[0006] 1) After the tower tube section is unfolded, it becomes a fan-shaped steel plate, and the radius of each fan-shaped steel plate is different, so the cutting efficiency of the fan-shaped steel plate groove has not been improved;
[0007] 2) The alignment of cylinder joints is time-consuming and labor-intensive, and the efficiency is low;
[0008] 3) The welding efficiency and welding quality of the butt weld of the tower shell have become a technical bottleneck;
[0009] 4) After the flange is welded, the flatness and parallelism are easy to be out of tolerance

Embodiment Construction

[0060] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0061] A method for manufacturing a main structure of a wind power generation tower, such as figure 1 As shown, the main structure of the wind power tower is composed of a base ring 1, a lower tower 2, a middle tower 3 and an upper tower 4 which are sequentially connected from bottom to top. The base ring 1 and each tower 2, 3, 4 are produced separately and connected by flange 5; the specific production process is as follows:

[0062] 1) Blanking and cutting:

[0063] The bodies of the base ring 1 and the tower tubes 2, 3, and 4 of each section are all conical cylinders, and the cylinders are composed of one or more cylinder sections 6, and each cylinder section 6 is made of steel plates with different thicknesses;

[0064] Firstly, each cylinder section 6 is lofted and expanded according to the construction drawing, and the expanded cylinder sect...

Abstract

The invention relates to a method for manufacturing the main body structure of a wind turbine tower. The method comprises the steps: 1 cutting raw materials; 2 preparing grooves; 3 coiling shell rings; 4 welding longitudinal seams of the shell rings; 5 installing and welding the shell rings and flanges; 6 installing and welding circular seams of the shell rings of a shell; 7 inspecting a shell finished product. The method has the advantages of reasonable work procedure arrangement and strict quality control, can reduce labor intensity and improve the manufacture quality and efficiency.

Description

technical field [0001] The invention relates to the technical field of steel structure manufacturing, in particular to a method for manufacturing a main structure of a wind power generation tower. Background technique [0002] As a new type of renewable energy, wind power has many advantages such as clean, environmentally friendly and sustainable development. The abundance of wind energy resources and the urgency of energy conservation and emission reduction have accelerated the development of wind power. my country started to develop wind power in the 1990s, and achieved a large-scale development at the beginning of this century, especially since 2005. [0003] In wind power generation equipment, the tower is an important part connected to the fan. It bears the thrust, torque, bending moment, gyro moment, vibration of the motor gearbox and the swing when the force changes on the impeller. The ambient temperature in the wind turbine area can reach as low as -40°C and as hi...
