Description

Technical Field

[0001] The invention belongs to the technical field of railway freight car maintenance, and more specifically, relates to a carriage welding adjustment device. Background Art

[0002] The end wall, side wall and chassis together constitute the main structure of the railway freight car loading compartment. The end wall is located at the front and rear ends of the railway freight car, and the side wall is located on the left and right sides of the car. The end wall is usually a plate-column structure, mainly welded by the upper end beam, corner column, end plate and cross belt, and the side wall is mainly welded by the side plate, diagonal brace and corner column.

[0003] In recent years, the vehicles that have undergone the maintenance and repair system reform have gradually expired, and the end plates and side plates have been seriously corroded and damaged. When repairing railway freight cars, it is necessary to replace the corroded and damaged side plates and end plates. When replacing the side plates and end plates, it is necessary to first dismantle and separate the corroded and damaged side plates and end plates using flame cutting or plasma cutting. According to previous maintenance experience and statistical results, most of the diagonal bracing components, cross straps and other components of the carriages are in good condition and do not need to be replaced or repaired. Therefore, the intact parts of the carriages need to be protected during dismantling to avoid unnecessary losses caused by excessive or erroneous dismantling.

[0004] After disassembly, the new side panels and end panels need to be welded to the carriage. In order to ensure the overall assembly size and welding quality of the railway freight car, it is necessary to accurately control the misalignment between the new side panels or end panels and the carriage, the assembly gap and other parameters, and at the same time control the welding deformation within a reasonable range. However, due to the high strength of the diagonal braces and cross straps, when adjusting the gap between the side panels and the diagonal braces, and the gap between the end panels and the cross straps, it is necessary to use a simple manual hand-held clamp with flame heating to adjust the diagonal braces or cross straps point by point. At the same time, the operators need to cooperate with each other to perform welding operations, which requires a huge workload for the operators and has low work efficiency. In addition, due to the reliance on manual hand-held clamps to apply force, the assembly gap is large, which affects the welding quality. Summary of the invention
