Abstract

The invention relates to the technical field of train production and manufacturing, and provides a vehicle body large part replacement method. The vehicle body large part replacement method comprises the following steps: (S1) a main frame is carried into a vehicle body; (S2) the main frame is connected with a telescopic support rod; (S3) the main frame is fixed on a baseplate in the vehicle body; and the telescopic support rod needing to be adjusted is determined according to a large part needing to be replaced; and (S4) the vehicle body large part is replaced. The method can prevent deformation of the vehicle body in replacement of the vehicle body large part, improves the structure rigidity of the vehicle body from the internal of the vehicle body, improves the stability of the vehicle body, and reduces the later procedure workload and the labor intensity. The method not only can satisfy the replacement requirements of large parts in different vehicle types, but also can largely reduce the working intensity of constructors.

Description

technical field [0001] The invention relates to the technical field of train production and manufacturing, in particular to a method for replacing large parts of a train body. Background technique [0002] The car body is a rigid fixed body composed of large parts such as the floor, roof, and side walls. Generally, the replacement process of large parts including floor panels, roofs, side walls, etc. includes interception, welding and other processes. Among them, during the replacement process of the large parts of the roof and side walls, the stress release will cause the car body to deform, which will affect the fit size and welding quality of the car body, and will affect the final assembly of the vehicle in the future. Moreover, the welding process of the car body itself will also release stress and affect the final assembly of the vehicle. [0003] When replacing large parts of the car body, in order to prevent the deformation of the car body, the traditional method g...
