Problems solved by technology

[0004] However, there are still some defects in the above patents. It achieves the effect of convenient maintenance, but it is connected and fixed by one-piece welding, which is not easy to disassemble and install, has poor impact resistance, and does not have the function of internal drainage. Therefore, we launched Rail vehicle dome structure

Abstract

The invention discloses a railway vehicle round top plate structure. The railway vehicle round top plate structure comprises a round top plate body, side round top plates and a round top plate connecting piece, first arc clamping blocks are symmetrically arranged on the inner side walls of the two ends of the round top plate body, first round top plate connecting protruding blocks are vertically and symmetrically arranged on the right side faces of the side round top plates, second round top plate connecting protruding blocks are vertically and symmetrically arranged on the left side of the round top plate connecting piece, and second arc clamping blocks are symmetrically arranged on the inner wall of the right end of the round top plate connecting piece. When the railway vehicle round topplate structure is used, the round top plate body, the side round top plates and the round top plate connecting piece are quickly combined and mounted into a whole through buckling connection of thefirst round arc clamping blocks arranged on one side of the round top plate body and the second round top plate connecting protruding blocks arranged on one side of the round top plate connecting piece, so that the round top plate structure can resist the impact of an external object, deformation and damage are avoided, the supporting stability of the round top plate is improved, and the service life of the round top plate is prolonged.

Description

technical field [0001] The invention relates to the technical field of dome plates, in particular to a rail vehicle dome plate structure. Background technique [0002] The rail vehicle dome plate in the prior art is composed of the dome plate main body, the dome plate connecting member and the side dome plate, and the dome plate main body, the dome plate connecting member and the side dome plate are fixed by seam welding after overlapping This welding method is not only difficult to detect the weld seam, but also inconvenient for maintenance, and the structural strength, stiffness, and sealing performance of the roof panel are poor, and generally the dome panel main body, the dome panel connecting member and the side dome panel are welded as a whole. Especially in rainy days, it is not convenient to discharge rainwater, resulting in a backlog, and the dome plates will be piled up for a long time to cause certain corrosion. Therefore, the existing technology cannot meet the r...
