Railway vehicle air conditioner flat top structure and railway vehicle

Abstract

The invention relates to the technical field of railway vehicles, and discloses a railway vehicle air conditioner flat top structure and a railway vehicle. The railway vehicle air conditioner flat topstructure comprises: a first end top plate structure, a first top plate, a second end top plate structure and a second top plate, wherein the first end top plate structure, the first top plate, the second end top plate structure and the second top plate are welded end to end to form a frame structure, each of the first end top plate structure and the second end top plate structure comprises an end top plate and an end top cross beam integrally connected with the end top plate, the middle area of the bottom wall of the end top cross beam is higher than the areas on the two sides, and the two sides of the end top cross beam are connected with the first top plate and the second top plate on the corresponding sides; and drainage grooves formed in the lower surface of the first top plate and the lower surface of the second top plate respectively, wherein through holes communicated with the drainage grooves in the corresponding sides are formed in the first top plate and the second top plate. The railway vehicle air conditioner flat top structure has the advantage of being free of water storage and water leakage.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a rail vehicle air-conditioning flat roof structure and a rail vehicle. Background technique [0002] The roof structure of the existing stainless steel rail vehicle is roughly divided into two types. The first is the high-arc roof structure. Due to the vehicle limit requirements, the air conditioner should meet the limit after installation. Therefore, the air-conditioning level installed on the high-arc roof structure The roofs are sunken air-conditioned flat roofs. The second type is the low-arc roof structure. Due to the low height of the low-arc roof structure, the air conditioner can be directly fixed on the roof through the mounting seat. Type air conditioner installation structure. [0003] Most of the existing air-conditioning flat roof structures are sunken, and the air-conditioning flat roof is provided with structures such as a drain outlet with a filter screen...

Problems solved by technology

At the same time, because the filter screen is directly fixed on the drainage tank by screws, and because the drainage tank is made by cold drawing process, and at the same time, in order to meet the needs of weight reduction of the car body, thick plates cannot be used, resulting in fewer effective threads of the screws, which may There is a risk that the screws will loosen and come off
