Problems solved by technology

[0002] At present, when the side roof profile of rail vehicles is installed with the side door mechanism and side wall trim, the installation plane needs to be welded on the corresponding parts of the side roof profile, which is not only inconvenient to install, but also due to welding deformation It is difficult to guarantee the flatness of the installation plane due to factors such as
In addition, in order to ensure the welding quality, the thickness of the installation plane is required to be thicker, thus increasing the weight of the side roof profile

Abstract

The invention relates to the technical field of railway vehicles, and provides a side top sectional material, a railway vehicle body and a railway vehicle. The side top sectional material comprises aside top body and an equipment mounting part, the side top body comprises an outer side skin and an inner side skin, and the inner side skin is provided with a first mounting groove; the equipment mounting part comprises a mounting transverse bar and a connecting longitudinal bar, a first end of the mounting transverse bar is connected to the outer side skin, a second end of the mounting transverse bar penetrates through the inner side skin and extends in the direction away from the outer side skin, a first end of the connecting longitudinal bar is connected to the second end of the mounting transverse bar, and a second end of the connecting longitudinal bar is connected to the first mounting groove. According to the side top sectional material, the installation stability of a side door mechanism and a side wall plate is improved, the structural strength and rigidity of the side top sectional material are improved, door area deformation is effectively prevented, and compared with the prior art, the influence of welding deformation and welding defects on the side top sectional material is reduced.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a side roof profile, a rail vehicle body and a rail vehicle. Background technique [0002] At present, when the side roof profile of rail vehicles is installed with the side door mechanism and side wall trim, the installation plane needs to be welded on the corresponding parts of the side roof profile, which is not only inconvenient to install, but also due to welding deformation It is difficult to guarantee the flatness of the installation plane due to other factors. In addition, in order to ensure the welding quality, the thickness of the installation plane is required to be relatively thick, thereby increasing the weight of the side roof profile. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. [0004] For this reason, the present invention proposes a side roof profile, which red...
