Grounding device and method for wind power steel pipe pile welding

Abstract

The invention discloses a grounding device and method for wind power steel pipe pile welding. The device comprises a guide rail, a guide rail and steel pipe pile connecting device, and a grounding device body, and can be used for welding grounding in a manufacturing process of a steel pipe pile of an offshore wind power generation project. In the manufacturing and welding process of the steel pipepile, a circle of aluminum alloy guide rail is additionally arranged on the outer wall of the steel pipe pile, and then grounding is conducted through a carbon rod with a balance weight device. By means of the grounding device, indirect grounding communication between the steel pipe pile and a welding machine is achieved, the influence of adverse effects such as the surface cleanliness and flatness of the steel pipe pile can be avoided, the welding grounding reliability is improved, and the influence of welding grounding faults on the manufacturing quality and efficiency of the steel pipe pile is effectively reduced.

Description

technical field [0001] The invention belongs to the field of wind power foundation manufacturing, and in particular relates to a grounding device and method for welding wind power steel pipe piles. Background technique [0002] The rapid development of offshore wind power generation has attracted more and more attention to the manufacturing quality and efficiency of wind farm equipment. As the most important part of the foundation of offshore wind turbines, steel pipe piles directly affect the quality and efficiency of offshore wind turbines. Construction period and service life. According to the manufacturing situation of steel pipe piles in recent years, the welding defects of steel pipe piles are still one of the main factors affecting the quality and efficiency of steel pipe pile manufacturing. [0003] According to the classification and analysis of manufacturing quality defects of steel pipe piles, the failure or failure of the welding grounding due to the influence o...

AI Technical Summary

Problems solved by technology

[0004] Nowadays, the grounding methods used by various production units in the welding process of steel pipe piles are direct grounding or roller frame grounding, which are greatly affected by the cleanliness and flatness of the steel pipe pile surface, and often cause steel pipe piles to be damaged due to welding grounding faults. The welding quality of the pile does not meet the standard requirements, or the manufacturing efficiency of the steel pipe pile is reduced, etc.
