Description

TECHNICAL FIELD

[0001] The present application relates to the field of rail transit vehicle body repair and maintenance tooling, and particularly relates to a narrow space repair and maintenance supporting device and a side wall repair and maintenance tooling with the device. BACKGROUND

[0002] The steel structure of a stainless steel rail vehicle body adopts a beam-column structure. In order to meet the strength requirement and weight requirement of the body steel structure, the wall plate generally adopts a 1.5 mm stainless steel plate. During the assembly and welding of the body steel structure, the side wall plate in the non-welding area is uneven due to the welding deformation and the size adjustment of the body, which cannot meet the flatness requirement in the steel structure technical conditions.

[0003] At present, a special repair and maintenance process is arranged after the assembly of the body steel structure to repair and maintain the flatness of the body steel structure. Since the stainless steel has poor thermal conductivity, the surface of the stainless steel is discolored after being heated by a flame, and the unevenness cannot be removed after passivation treatment. In the body repair and maintenance process, the operator detects the flatness of the side wall surface by using a straightedge and a feeler gauge, marks the position where the flatness of the wall plate is out of tolerance, and then hammers after padding a felt on the surface. Since the inside of the deformed area of the wall plate is mostly without a beam column, the wall plate becomes concave after being hammered. The areas that are difficult to repair and maintain by hammering can only be repaired and maintained by adjusting the beam column near the wall plate to improve the flatness of the wall plate.

[0004] The existing repair and maintenance process can only handle the wall plate with relatively gentle changes, and cannot handle the wall plate with local flatness changes. The flatness can only be controlled by increasing the process structure beam or giving up the flatness. Since the inside of the wall plate is mostly without support, hammering produces hammer marks, which affects the appearance quality of the body, and affects the sealing of the door unlocking mechanism and the external installation at individual positions.

[0005] In addition, the distance between the side walls on both sides of the body is affected by the welding deformation and the size adjustment of the body after the assembly and welding of the body side wall. The traditional way is to use an expansion rod to tighten and repair, which is time-consuming and labor-intensive.

[0006] Therefore, based on the above problems, how to provide a narrow space repair and maintenance supporting device and a side wall repair and maintenance tooling with the device has become an important technical problem to be solved by those skilled in the art. SUMMARY

[0007] The purpose of the present application is to overcome the defects existing in the prior art, provide a narrow space repair support device and a side wall repair tool with the device, which can realize the installation of support between the beams and columns in the vehicle body, realize the support function of the wallboard, avoid the generation of hammer marks on the surface of the wallboard during the repair process due to excessive force, and can quickly conduct heat dissipation in the contact area with the wallboard, avoid the wave deformation problem caused by heat concentration during heating repair, improve the appearance quality of the vehicle body steel structure, and reduce the labor intensity of the operator.
