Vehicle roof fairing installing method of rail vehicle

Abstract

The invention relates to a vehicle roof fairing installing method of a rail vehicle. The vehicle roof fairing installing method comprises the following steps that a fixing framework and an installing seat are welded at the inner and outer sides of a vehicle roof flat plate; a Z-shaped connecting plate is welded at the inner side wall of the upper end of an arc-shaped fairing plate; a hinge is welded at the inner side wall of the lower end of the arc-shaped fairing plate; the fairing plate is hoisted in place; the Z-shaped connecting plate is fixedly arranged at the upper surface of the fixing framework; the gap between the hinge and the vehicle body flat top and the radian of the fairing plate are regulated in a mode of additionally adding a regulating gasket between a second component of the hinge and the installing seat; the position of the fairing plate is regulated in the longitudinal direction, and the gap between the adjacent fairing plates is eliminated; and screw bolts arranged at the upper and lower end parts of the fairing plate are fastened. The vehicle roof fairing installing method has the advantages that the work procedure is simple, the operation is convenient, the production efficiency is high, the gap between the hinge and the vehicle body flat top and the radian of the fairing plate can be respectively regulated, and the longitudinal gap can also be regulated. The circular arcs of installed fairings are consistent, the aesthetic degree is high, and in addition, accumulation water at the flat top can be ensured to be discharged out from the gap between the fairing and the vehicle top.

Description

technical field [0001] The invention relates to a rail vehicle roof guide cover installation method, which belongs to the technical field of rail vehicle body structures. Background technique [0002] Usually, the flat roof of the car body is relatively short, and generally only one fairing plate is needed to cover it. However, for a flat roof with a large length, one fairing plate cannot reach the length of the flat roof of the car body, and multiple fairings are required for assembly. During the assembly process, how to conveniently adjust the multiple shrouds to the same circular arc requires a more suitable connection structure to ensure. [0003] After the wind deflector is installed, on the one hand, it needs to have a better appearance, and on the other hand, it must be easy to drain. The wind deflector used in the past is composed of two parts: the frame and the deflector plate. The frame is welded on both sides of the flat roof, and the flat roof It is easy to for...
