Description

Technical Field

[0001] The invention relates to automatic box beam welding equipment, belonging to the technical field of 00. Background Art

[0002] Box girder is a kind of beam in bridge engineering. It is hollow inside and has flanges on both sides of the upper part, similar to a box, hence the name. It is divided into single box, multiple box, etc. Box girder can be classified in different ways. According to the material: Reinforced concrete box girder: divided into prefabricated box girder and cast-in-place box girder. Prefabricated box girder is prefabricated in an independent site and can be erected after the lower project is completed with the help of a bridge-erecting machine, which can speed up the progress of the project and save construction time; cast-in-place box girder is mostly used for large continuous bridges. Steel box girder: also called steel plate box girder, is a common structural form for large-span bridges, mainly used for bridges with larger spans. Steel box girder is generally processed in the factory and then transported to the site for installation. There are all-steel structures and some with reinforced concrete paving layers. According to the construction method: Prefabricated box girder: prefabricated in an independent site, and then installed using a crane or a bridge-erecting machine. Cast-in-place box girder: cast at the bridge site, requiring scaffolding or full-floor support method for support.

[0003] Authorization announcement number (CN218695608U); An intelligent processing system for a box girder steel frame, comprising a frame and a mobile platform located above the frame, on which a welding manipulator and a picking manipulator arranged toward the frame are suspended; the frame comprises a bracket, at least one conveyor belt group, a stirrup positioning device, a steel bar positioning device and a steel bar supporting device; compared with the prior art, through the arrangement of the frame and the mobile platform, the stirrups can be placed into the frame by hoisting, and the stirrups can be positioned by the conveyor belt group and the stirrup positioning device, so that the stirrups have better accuracy, and at the same time, the longitudinal steel bars are welded by the distribution placement of the upper longitudinal steel bars and the lower longitudinal steel bars, and the longitudinal steel bars and stirrups are welded by means of a manipulator, which greatly reduces the labor demand of workers and saves labor costs while ensuring the stability of each component.
