Railway vehicle car roof wind deflector

Abstract

A railway vehicle car roof wind deflector comprises an arc-shaped wind deflector board. A fixing frame is welded on the inner side of a flat roof of a car body. An installing base is welded at the outer end of the flat roof of the car body. A reversed-T-shaped slide groove is arranged at the upper end face of the installing base along the longitudinal direction of the flat roof of the car body. A Z-shaped connecting board is welded at the upper end of the arc-shaped wind deflector board and connected with the upper end of the fixing frame through bolts. Hinges are welded at the lower end of the arc-shaped wind deflector board and fixed with the installing base through bolts. An adjusting gasket is arranged between the hinges and the installing base. A longitudinal space can be conveniently adjusted through the wind deflector board by using of the reversed-T-shaped slide groove. The sizes of gaps between the wind deflector and the flat roof can be adjusted through adjustment of a gasket, and ponding of the flat roof can be discharged from the gaps between the wind deflector and the flat roof. The gaps are even in size. The radian of the wind deflector board can be adjusted through the adjustment of the gasket, arcs of the adjacent wind deflector boards can be coincident, and degrees of beauty are improved. The railway vehicle car roof wind deflector is convenient to install and high in production efficiency.

Description

technical field [0001] The invention relates to a rail vehicle roof deflector and belongs to the technical field of rail vehicle body structure design. 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 form stagnant water. ...
