Description

Technical Field

[0001] The present invention relates to the technical field of wind power equipment, and in particular to a processing device and process for a wind power tower transition section. Background Art

[0002] In the field of wind power generation, the manufacturing of wind power towers is a crucial link. Its quality and stability are directly related to the operating efficiency and safety of wind power generation equipment. As a key component of the tower, the wind power hybrid tower transition section usually adopts a conical cylindrical structure to adapt to the force requirements under different heights and wind speed conditions. This transition section has the characteristics of short length, large diameter (such as a diameter of 4.8 meters) and thick steel plate, which brings considerable challenges to its processing and welding.

[0003] In the manufacturing process of the transition section, the circumferential welding at both ends is a crucial step. Since the transition section is a conical structure, traditional welding methods such as manual welding or gas shielded welding are difficult to meet the needs of large-scale production in terms of efficiency and quality control. Therefore, submerged arc welding, as an efficient and stable welding method, is widely used in the circumferential welding of the transition section of the wind turbine tower.

[0004] When performing submerged arc welding, the transition section needs to rotate on the roller to ensure that the weld can be evenly heated and form a good welding quality. However, since the transition section is conical and flanges need to be welded at both ends, it is easy to produce longitudinal slip during the rolling process on the roller. This slip will not only cause the weld to be unable to be accurately positioned and affect the welding quality, but also the long-term accumulated slip may also cause huge safety hazards. For this reason, the present invention proposes a wind turbine tower transition section processing device and process to solve the above problems. Summary of the invention
