Abstract

The invention provides a modular roof structure for rail vehicles, which belongs to the technical field of rail vehicles, and includes an air-conditioning air duct, a skeleton sleeved on the air-conditioning air duct, a middle roof arranged at the bottom of the air-conditioning air duct, and a handrail arranged on the skeleton and the limit part; the hanging code is used to connect with the C-shaped groove on the roof; the limit part is used to limit the line between the two ends of the armrest to be parallel to the length direction of the middle roof when the armrest is installed on the frame; the frame It includes two sleeve parts respectively sleeved at both ends of the air-conditioning air duct, and a frame connecting the two sleeve parts. The limiting part is arranged on the frame; The rail vehicle modular roof structure provided by the present invention realizes the modular installation of the roof structure, simplifies the technological process of the roof structure, reduces the workload of roof structure installation, and improves the installation speed of the roof structure.

Description

Modular roof structure for rail vehicles technical field The invention belongs to the technical field of rail vehicles, and more specifically, relates to a modular roof structure for rail vehicles. structure. Background technique The interior roof is the main component of the interior decoration of the rail vehicle, while the interior roof is other components in the vehicle (such as empty space). Air ducts, interior armrests, etc.) provide installation interfaces. At present, the middle roof structure of rail vehicles mostly adopts the secondary frame and middle roof. Structural form of plate split installation. The commonly used materials for the middle roof are aluminum plate, aluminum honeycomb, etc. The secondary skeleton is mostly assembled with aluminum profiles made. This kind of structure requires that the secondary frame, air-conditioning duct, middle roof and handrail must be installed separately. When installing, first The skeleton hanging code is co...
