Description
Technical Field
The invention belongs to the technical field of railway vehicles, and particularly relates to an integrated structure on a constant-section A-shaped stainless steel railway vehicle sliding plug door system door.
Background
In the existing railway vehicle structure, an A-type stainless steel vehicle usually adopts a combined structure of an equal-section vehicle body and a built-in door or a non-equal-section vehicle body and a plug door, and the application of the combined structure of the equal-section vehicle body and the plug door of the domestic A-type stainless steel vehicle is precedent at present. Most of the domestic A-type vehicle bodies are made of aluminum alloy bodies, the materials and the process are mature, the welding is easy, the interface size stability is good, the system integration is easy, and the batch production is easy. The A-type stainless steel car body can be free from coating, the material strength is good, the air tightness of the integrated structure of the sliding plug door system is good, dust, sundries and water cannot enter the inside of the car, and the comfort of passengers is better. However, the rigidity of the stainless steel car body door opening area of the combined structure of the equal-section car body and the sliding plug door is poor, if the integrated structure on the conventional stainless steel car body door is adopted, the rigidity of the car body is weak, the sliding plug door needs to be provided with a bearing structure above the door opening, the strength of the area above the door opening cannot meet the requirement, the influence on the natural vibration frequency of the car body is large, and the use requirement is not met.
Disclosure of Invention
The invention aims to provide a novel integrated structure on a door of a stainless steel railway vehicle sliding plug door system, which improves the rigidity of a vehicle body door opening region and increases the bearing capacity by increasing the section area of the door upper region, and solves the actual problem that the rigidity of the stainless steel vehicle body door opening region with equal sections is weaker.
In order to achieve the purpose, the invention provides an integrated structure on a constant-section A-shaped stainless steel railway vehicle sliding plug door system door, which comprises a closed cold-formed steel framework, a sliding groove assembly and a connecting plate. The door structure is characterized in that an opening adaptive to a door is formed in the lower side of the connecting plate, the upper side of the connecting plate is fixedly connected with a roof side beam, two sides of the door of the connecting plate are fixedly connected with an upper window beam, the outer side of the connecting plate is fixedly connected with a steel skeleton along the longitudinal direction, the inner side of the connecting plate is fixedly connected with a sliding chute of a connecting door mechanism, the outer side of the steel skeleton is fixedly connected with an upper wallboard, and the lower side of the steel skeleton is fixedly connected with upright posts at two sides of the door opening. The sliding groove assembly is formed by fixedly connecting two C-shaped sliding grooves side by side, and the sliding grooves are provided with fabrication holes facilitating assembly of a door mechanism.
Compared with the prior art, the invention has the following positive effects:
the traditional constant-section stainless steel car body structure is adopted, the car body rigidity is weak, the sliding plug door needs to be provided with a bearing structure for bearing the weight of the sliding plug door at a doorway, and the car body deforms greatly after bearing. This novel integrated configuration on stainless steel automobile body door contains spout and constitutes, connecting plate, steel skeleton, and integrated configuration passes through boundary beam, top wall board, window entablature to be fixed in automobile body door upper region on the door, has increased section area on the section stainless steel automobile body door such as, is showing and has improved section stainless steel automobile body rigidity such as, satisfies the requirement that the region bore on the door, is showing and has improved section stainless steel automobile body rigidity such as, satisfies automobile body operation requirement.
