Description

Technical Field

[0001] The present application relates to the technical field of wind power generation, and in particular to a small wind power beam welding system. Background Art

[0002] With the continuous development and improvement of wind power, the importance of wind turbine beams has become increasingly prominent. Wind turbine beams are one of the most important structural components in wind power generation systems. They have multiple functions such as bearing the load of blades and electromechanical equipment, transmitting power, and resisting wind loads. In the production process of wind turbine beams, welding is a very important process. The quality of welding directly affects the production quality of wind turbine beams. Due to the large size of the components that make up the wind turbine beams, the existing fixing devices are unable to stably position the components, resulting in misalignment of the welding position and affecting the welding quality. In addition, they can only adapt to the fixing of wind turbine beams of a single size, with a small range of adaptability. The welding angle cannot be flexibly adjusted, and efficient automatic welding of the components cannot be achieved. Utility Model Content
