Integrated structure on door of uniform-section A-type stainless steel rail vehicle sliding plug door system

Abstract

The invention discloses an integrated structure on a door of a uniform-section A-type stainless steel rail vehicle sliding plug door system. The integrated structure comprises a closed cold-formed steel framework, a sliding groove assembly and a connecting plate. An opening adapted to a doorway is formed in the lower side of the connecting plate; wherein the upper side of the connecting plate is fixedly connected with a roof boundary beam, the two sides of the doorway of the connecting plate are fixedly connected with an on-window cross beam, the outer side of the connecting plate is longitudinally and fixedly connected with the steel framework, the inner side of the connecting plate is fixedly connected with a sliding groove of a connecting door mechanism, the outer side of the steel framework is fixedly connected with an upper wallboard, and the lower surface of the steel framework is fixedly connected with stand columns on the two sides of the doorway. The sliding groove assembly isformed by fixedly connecting two C-shaped sliding grooves side by side, and the sliding grooves are provided with auxiliary holes facilitating assembly of the door mechanism. The novel on-door integrated structure is fixed to the upper area of a vehicle body door through the boundary beam, the upper wall plate and the window cross beam, the sectional area of the upper area of the equal-section stainless steel vehicle body door is increased, the rigidity of an equal-section stainless steel vehicle body is remarkably improved, and vehicle body using requirements are met.

Description

technical field [0001] The invention belongs to the technical field of rail vehicles, and in particular relates to an integrated structure on the door of an A-shaped stainless steel rail vehicle plug door system with equal section. Background technique [0002] In the existing rail vehicle structure, the A-type stainless steel car often adopts the combination structure of equal-section car body and built-in door or non-equal-section car body and plug door. At present, domestic A-type stainless steel car has no equal-section car body and plug Application precedent of door combination structure. Most of the domestic A-type car bodies are made of aluminum alloy, with relatively mature materials and processes, easy welding, good dimensional stability of the interface, easy system integration, and easy mass production. The A-type stainless steel car body can be free of painting, the material strength is good, and the integrated structure of the sliding door system has good airti...
