Problems solved by technology
[0003] The welding of the existing U-rib panels generally only welds the outer corner joints. In order to strengthen the strength of the steel box girder and prolong its service life, a technology of welding the inner corner joints has also appeared in recent years, but the inner and outer Welding operations are usually cumbersome, inefficient, and cannot be automated

The invention provides a U-rib welding system which comprises an inner welding machine, an outer welding machine, walking tracks and a rack. The inner welding machine comprises a host, connecting rodsand an inner welding robot; one ends of the connecting rods are connected with the host; the other ends of the connecting rods are connected with the inner welding robot; the outer welding machine comprises a portal frame and multiple welding execution parts arranged on the portal frame; the multiple welding execution parts are arranged side by side; the spaces between the welding execution partsare adjustable; and the inner welding machine and the outer welding machine walk along the walking tracks, and are used for respectively welding inner corner joints and outer corner joints of U ribsto be welded and a bottom plate to be welded which are placed on the rack. According to the U-rib welding system, the welding of the inner corner joints and the outer corner joints of U ribs of a steel box girder panel can be accomplished on one same rack, so that the welding efficiency is greatly improved.
Description
technical field [0001] The invention relates to the field of welding technology, in particular to a welding system for U ribs. Background technique [0002] The steel box girder is an important part of the load-bearing structure of the bridge. The steel box girder is generally an orthotropic steel bridge deck, which is mainly used to provide support and avoid bridge deformation. Steel box girders generally include structures such as roof and floor. At present, orthotropic steel bridge decks are widely used in the manufacture of long-span bridges. Both the top and bottom plates of bridges adopt this structure, and the orthotropic steel bridge decks are welded by U ribs and bottom plates. [0003] The welding of the existing U-rib panels generally only welds the external corner joints. In order to strengthen the strength of the steel box girder and prolong its service life, the technology of welding the internal corner joints has also appeared in recent years, but the interna...
