Description

Technical Field

[0001] The present invention relates to the technical field of welding devices, in particular to a rapid welding device for iron tower components. Background Art

[0002] The tower foot is a crucial component of a transmission tower. Located at the base of the tower, it's the part of the tower that meets the ground. It primarily bears the tower's vertical and horizontal loads, ensuring its stability and transferring its weight to the ground. It also resists horizontal loads caused by factors like wind, deadweight, and temperature fluctuations. The tower foot consists of a tower frame, a base plate, and connectors, and is machined into a stable cross-shaped structure.

[0003] Conventional welding often involves placing tower foot components on a workbench for welding. This prevents the upper connecting piece from being fixed, leading to misalignment or displacement between the connecting plate and the base plate during welding. This can cause deviations in the verticality of the tower foot after assembly. Traditional manual welding is also inefficient and significantly affected by the welder's skill level and experience. Different workers' operations can lead to inconsistent welding quality, making it difficult to ensure stable and consistent tower foot welding. During manual fixed welding, improper welding techniques and operations can easily lead to weld deformation and stress, compromising the stability and safety of the structure. Furthermore, existing equipment, which primarily focuses on single-direction welding, is unable to handle the complex internal structure of the tower foot, significantly increasing production costs.
