Embodiment Construction

[0016] Such as figure 1 , figure 2 As shown, the movable roof structure of the railway passenger car in this embodiment includes a flat top part 3, an arc frame 2 fixed on the front and rear sides of the flat top part 3, a dome part 1 fixed with the arc frame 2, and a flat top part. 3. The arc frame 2 and the dome part 1 are all fixed on the welding frame. The flat top part 3 is fixed with the equipment mounting seat 5 and the air guide tube 4. The left and right sides of the flat top part 3 have side beams, and the side beams Welded lugs. A movable roof installation frame 9 is arranged laterally on the passenger car dome plate 11 and bolts 7 are fixed at intervals. The bolts 7 are fitted with weights 8, and a roof curved beam 10 located on the lower surface of the passenger car dome plate 11 is located below the movable roof installation frame 9. . The lower bottom surface of the dome part 1 is pressed on the movable roof installation frame 9 through the sealing rubber st...

Abstract

The invention relates to a drop head structure for a railway passenger train. The drop head structure for the railway passenger train comprises a ceiling part, arc-shaped frames fixed on the front side and the rear side of the ceiling part, and a round top part fixed to the arc-shaped frames, wherein the ceiling part, the arc-shaped frames and the round top part are respectively fixed on a welded framework; an equipment installation seat is fixed on the ceiling part; a drop head installation frame is arranged along the transverse direction on a round top plate of the passenger train, and bolts are fixed on the round top plate of the passenger train at intervals; iron weights sleeve the bolts; the lower bottom face of the round top part is pressed on the drop head installation frame through a sealing rubber strip; the head parts and the tail parts of the iron weights are respectively pressed on the upper surfaces of the round top part and the round top plate of the passenger train, so that the round top part and the round top plate of the passenger train are fixed and sealed. Due to the utilization of the scheme, according to the limit requirements of different trains, only the drop head structure needs to be designed, so that the requirement on the installation height of the equipment can be met, the production cost is greatly reduced, and the production efficiency is high.

Description

technical field [0001] The invention relates to a movable roof structure for railway passenger cars and belongs to the technical field of rail vehicle body structures. Background technique [0002] Different countries and regions have different railway vehicle limits. Vehicle constraints have always restricted the use of the space above the roof, yet the roof needs to have enough room to install equipment. This forms a pair of contradictions. If the roof of the whole vehicle is designed separately according to different vehicle limits, it will increase the product development cycle and cost, and easily cause waste of resources. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a movable roof structure for railway passenger cars by overcoming the above-mentioned shortcomings of the prior art. [0004] In order to solve the above technical problems, the movable roof structure for railway passenger cars provided by...
