Description

Technical Field

[0001] The utility model relates to the technical field of steel box girder transportation auxiliary equipment, in particular to a universal steel box girder assembled tire frame. Background Art

[0002] Steel box girder frame is a special process equipment, which is mainly used in the assembly and welding process of steel box girder, and plays a key role in load bearing and support. Steel box girder frame is usually composed of metal structure. Its design is based on the specific steel box girder structure, weight and assembly and welding process. The main forms are frame structure and pillar structure.

[0003] For example, the Chinese utility model patent disclosed by announcement number CN213702357U: a modular steel box girder frame, which divides the entire steel box girder frame into frame units that are spaced at intervals at the bottom of the steel box girder to be assembled along the length direction of the steel box girder to be assembled. The number of frame units can be freely increased or decreased according to the length of the steel box girder, so as to adapt to steel box girders of different lengths. Firstly, the two supporting columns of the application are connected by a number of diagonal braces, which makes the overall structure not convenient to disassemble and adjust. Secondly, the application supports the steel box girder by the box girder brackets on the support columns, but due to the structural setting of some steel box girders, that is, the non-planar structure of the bottom of some steel box girders, it is impossible to adjust the supporting surface according to the steel box girders of different structures, which makes it easy for the steel box girder to shake when supporting the steel box girder, resulting in errors in the assembly of the steel box girder.
