Description

Technical Field

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

[0002] The tower foot is an important part of the transmission tower. It is located at the bottom of the tower and is the part of the tower that contacts the ground. It mainly bears the vertical and horizontal loads of the tower, ensures the stability of the tower, transfers the weight of the tower to the ground, and resists the horizontal load caused by wind, deadweight, temperature difference and other factors. The tower foot consists of a tower frame, a base plate, and connectors, and is processed into a stable cross-shaped structure.

[0003] In the prior art, the tower foot components are often placed on a workbench for welding. The connecting pieces at the upper end of the tower foot cannot be fixed, resulting in the phenomenon of misalignment or displacement between the connecting plate and the bottom plate during welding, which leads to deviation in the verticality of the tower foot after splicing. In addition, the efficiency of traditional manual welding is low. Manual welding is greatly affected by the skill level and experience of the welders. The operation of different workers may lead to unstable welding quality, making it difficult to ensure the stability and consistency of the tower foot welding. During manual fixed welding, due to improper welding process and operation, welding deformation and stress are easily generated, affecting the stability and safety of the structure. In addition, the existing equipment is mostly for welding in a single direction, which cannot cope with the complex structure inside the tower foot, resulting in a significant increase in production costs.
