Railway passenger train body and railway vehicle

Abstract

The invention provides a railway passenger train body and a railway vehicle. The train body comprises a train body steel structure, wherein the train body steel structure comprises train body side walls and a train body top part, the inner side of the train body top part is provided with at least two inner top plate assemblies in the longitudinal direction, each inner top plate assembly comprises a skeleton, a middle top plate and side top plates, the side top plates are respectively positioned at the two sides of each middle top plate, the skeleton comprises at least two longitudinal beams and at least two transverse beams, each middle top plate covers under the skeleton, the two sides of each middle top plate are respectively and fixedly connected with the two longitudinal beams, the butting part of the middle top plates of the two adjacent top plate assemblies is provided with a gap blocking cover plate which is used for blocking a gap between the middle top plates, the two ends of the gap blocking cover plate are respectively and fixedly connected with the two longitudinal beams, one side, facing the skeleton, of each side top plate is respectively and fixedly connected with the corresponding longitudinal beam, and the other side of each side top plate is fixedly connected with the corresponding train body side wall. The railway passenger train body has the advantages that the assembly operation is convenient, the assembly efficiency is improved, and the overhauling and maintenance are conveniently implemented.

Description

technical field [0001] The invention relates to a railway vehicle manufacturing technology, in particular to a railway passenger car body and a railway vehicle. Background technique [0002] The railway passenger car body bears the important role of carrying passengers, which mainly includes the steel structure of the car body and interior panels. Among them, the steel structure of the car body includes the side walls of the car body on both sides and the car body roof on the top, and the interior trim includes the side wall panels arranged on the inner surface of the side walls of the car body and the inner roof panel installed on the inner side of the car body roof. [0003] In the existing technology, such as figure 1 As shown, the inner roof includes a middle roof installed on the roof of the car body through a joist assembly and side roofs 12 located on both sides of the middle roof 11, and the side roof 12 is screwed to the light on the joist assembly 13 toward the si...

Problems solved by technology

Wherein, the middle top board 11 comprises a plurality, and is arranged in sequence along the longitudinal direction, and correspondingly, the side top board 12 also includes a plurality of longitudinally arranged ones, each middle top board 11 and side top board 12 edges are respectively provided with inserting parts, and adjacent Between the middle top boards 11, between the adjacent side top boards 12, and between the adjacent middle top boards 11 and the side top boards 12 are connected through the above-mentioned specific matching plug-in parts, so that when installing, it is necessary to strictly follow the construction The process installs the middle roof, side roof and related accessories one by one, which is inconvenient to operate and low in efficiency; in addition, in the follow-up maintenance process, the middle roof or side roof cannot be removed separately, so the entire inner roof inside the car body needs to be removed. Repair and maintenance can only be carried out after dismantling, which is very inconvenient
