Abstract

The invention discloses an integral correction device for a long and thin beam structure and a correction method, and belongs to the field of welded structure correction. In order to solve the problem in the prior art that the long and thin beam structure is liable to deform during the welding process, the correction device is formed by assembling a plurality of correction units, and two adjacent correction units are fixedly connected through a connection mechanism, wherein each correction unit structurally comprises an adjusting support, a platform which is arranged on the adjusting support and used for carrying a beam and compaction mechanisms which are arranged on the two sides of the platform and used for compacting the beam. The correction method adopts the correction device to correct the long and thin beam structure with good correction effect. The invention effectively overcomes the difficulty in correction process of the beam due to length, tool and other factors, can integrally handle welding deformation of the beam, makes the correction process more centralized and simple, greatly increases work efficiency, and reduces the labor intensity of workers.

Description

technical field [0001] The invention relates to the field of welding structure rectification, in particular to an overall rectification device and rectification method for a long and thin string beam structure, which is mainly used for post-welding rectification of long and thin string beams of electric locomotive bodies, and is also applicable to other similar long and thin string beams Correction of thin beam structure. Background technique [0002] in HX D 1B, HX D In the side structure of 1C and other locomotives, each car has 4 string girders, which are slender beam structures surrounded by inner and outer plates with a thickness of 6mm. The area is surrounded by an irregular quadrilateral, and the length of the string girder is up to 16m. In the prior art, this kind of long and thin string girder structure is usually welded and rectified in sections. After each segment is assembled, welded and rectified separately, Then splice them into a whole, and then correct the...
