Embodiment Construction

[0034] The present invention will be specifically introduced below in conjunction with the embodiments.

[0035] This embodiment is a large-diameter onshore wind power tower manufacturing process. The tower is formed by connecting several tower sections. The specific steps are as follows:

[0036] Step 1: Inspect the plate used to roll the tower tube section, take the plate that passes the inspection, cut it according to the design size, and cut it into a bevel to make a fan-shaped plate;

[0037] Step 2: roll the fan-shaped plate after beveling to form a tower tube section and adjust the circle of the rolled tower tube section;

[0038] Step 3: Carry out spot welding positioning on the longitudinal seam of the tower tube section after being rolled and calibrated, and check the wrong edge; then weld the longitudinal seam of the tower tube section, grind the weld seam after welding, and then perform After the welding of the tower section, the circle is adjusted twice and the n...

Abstract

The invention discloses a manufacturing process of a large-diameter land wind power tower. The tower is formed by connecting a plurality of tower barrel sections. The manufacturing process comprises the following specific steps: inspecting a plate, then carrying out numerical control cutting, blanking and beveling to obtain a fan-shaped plate; rolling the fan-shaped plate to obtain tower barrel joints, and rounding the tower barrel joints; carrying out spot welding positioning and misalignment inspection on the longitudinal joints of the tower barrel joints; then welding longitudinal joints of the tower barrel joints, polishing welded joints, carrying out secondary roundness correction, and carrying out nondestructive testing; carrying out sanding and paint spraying treatment on the tower barrel joints subjected to longitudinal seam welding; assembling the tower barrel joints sequentially, carrying out staggered joint inspection and assembly welding, and carrying out nondestructive testing after the welded joints are polished; welding flanges to the two ends of the tower barrel sections respectively, carrying out surface anti-corrosion treatment and internal part assembling, and finally carrying out finished product inspection; and manufacturing the wind power tower after the multiple matched tower barrel sections are assembled in pairs through flanges. The welding seam quality can be effectively improved, and the safety of the tower is improved.

Description

technical field [0001] The invention relates to a large-diameter onshore wind power tower manufacturing process, which belongs to the field of wind power towers. Background technique [0002] In recent years, global energy and environmental issues have become increasingly severe, and the wind power industry has entered a period of rapid development. As the foundation of the wind turbine, the importance of the wind power tower is self-evident. The wind power tower is the tower of wind power generation. It mainly plays a supporting role in the wind power generation unit and absorbs the vibration of the unit at the same time. During the construction of wind power towers, the ellipticity of the tower, the longitudinal seam of the tower section and the welding of the girth seam between the tower sections have always been the difficulties in the manufacture of the tower. Different technological processes and different operation sequences will affect the control of manufacturing p...
