Description

Technical Field

[0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a welding system for a box beam. Background Art

[0002] The cross-sectional shape of the box beam is the same as the usual box cross-sectional shape, so it is called a box beam. The box beam is usually formed by combining several parts, such as the cover plate and the web plate, the partition plate, and the bottom plate. The box beam has certain advancement and superiority. It belongs to the economical cross-sectional combination structure in terms of mechanical properties and is often used in larger load-bearing structures such as gantry cranes and crane ships. Box-type structural beams (columns) are widely used in building steel structures, especially in high-rise or high-rise building structures, but the internal partition welding mostly adopts the melting nozzle type electroslag welding method.

[0003] During the assembly and welding process of the box beam side plates and steel bars, workers are required to cut the steel bars into the required length, then place the steel bars in designated positions at certain intervals, and finally weld the steel bars to the side plates.

[0004] However, welding the steel bars on the side plates in the above manner is prone to errors in the length of the steel bars or inaccurate positioning and spacing of the steel bars due to manual operation. At the same time, this method requires more labor costs and time in production. Summary of the invention

[0005] The purpose of the present invention is to at least solve the problem of inaccurate steel bar positioning and spacing due to manual operation during the existing box beam side plate and steel bar assembly process. This purpose is achieved through the following technical solutions:
