Problems solved by technology

[0003] In the prior art, after the assembly of the H-shaped steel on the tire frame is completed, the assembled H-shaped steel is hoisted and placed on an inclined welding support for submerged arc welding. H-shaped steel turns over to another weld for welding, and an H-shaped steel beam has a total of 4 welds, that is, to complete the welding construction of an H-shaped steel beam, it needs to turn over 4 times. A large number of turning and hoisting operations will not only easily cause H The deformation of the section steel increases the follow-up correction work, reduces the overall production quality, and increases the labor intensity of the lifting personnel, resulting in cost waste
In addition, the assembly and welding of H-beams are carried out at different stations, that is, the assembled H-beams need to be hoisted to the welding station, and after moving the stations, it is necessary to reposition or add shape-retaining reinforcement before proceeding to the next step , the process is cumbersome and complicated, which makes the assembly and welding of H-beams inefficient

Abstract

The invention provides an H-shaped steel overturning assembling and welding auxiliary tool. The H-shaped steel overturning assembling and welding auxiliary tool comprises a connecting steel pipe, positioning devices, end fixing devices and supporting devices, and the two ends of the connecting steel pipe are connected with the positioning devices for fixing H-shaped steel correspondingly; the bottoms of the end fixing devices are connected with a pallet truck, the end fixing devices are provided with rotating shafts, all the rotating shafts and the connecting steel pipe are connected with thepositioning devices, and the supporting devices are movably arranged on the lower middle portion of the connecting steel pipe; and the positioning devices are provided with first positioning holes, the end fixing devices are provided with second positioning holes, and the positioning devices are rotatably fixed at different angles between the second positioning holes and the first positioning holes through plug pins. In order to achieve the same purpose, the invention further provides an H-shaped steel overturning assembling and welding method. According to the H-shaped steel overturning assembling and welding method and the auxiliary tool thereof adopting the technical scheme, assembling and welding are conducted on a same station, the subsequent H-shaped steel correction work is reduced,the assembling and welding efficiency of the H-shaped steel is improved, and the construction cost is saved.

Description

technical field [0001] The invention relates to the technical field of assembly and welding of H-shaped steel, in particular to a method for turning over and welding an H-shaped steel and its auxiliary tooling. Background technique [0002] For a welded steel beam with an "H-shaped" section, the H-shaped steel includes a web and two panels located on the left and right sides of the web, and the cross-section of the entire H-shaped steel presents an "H-shaped". [0003] In the prior art, after the assembly of the H-shaped steel on the tire frame is completed, the assembled H-shaped steel is hoisted and placed on an inclined welding support for submerged arc welding. H-shaped steel turns over to another weld for welding, and an H-shaped steel beam has a total of 4 welds, that is, to complete the welding construction of an H-shaped steel beam, it needs to turn over 4 times. A large number of turning and hoisting operations will not only easily cause H The deformation of the se...
