High-speed rail roof structure

Abstract

The invention relates to the technical field of high-speed rails, and particularly discloses a high-speed rail roof structure. The high-speed rail roof structure comprises an end top assembly; the endtop assembly comprises end top top channel steel, a left end top bent beam, a right end top bent beam, an end top channel steel assembly and an end top plate. The left end top bent beam is welded onthe outer wall of one side of the end top top channel steel; the right end top bent beam is welded to the outer wall of the other side, away from the left end top bent beam, of the end top top steel channel, the end top steel channel assembly comprises a connecting block and an end top lower plate, and steel channel blocks distributed at equal intervals are welded to the outer wall of the bottom of the end top steel channel and the outer wall of the top of the end top lower plate. The high-speed rail roof structure has the beneficial effects that the top plate and the low fixed plate can achieve the heat insulation effect on high temperature generated by sunlight on the roof, the situation that the temperature in the vehicle rises too fast after the carriage roof is exposed to the sun canbe avoided, the use amount of cold air can be reduced, more cold air is saved, the end top stand columns can be fixed conveniently through the multiple steel channel blocks, and the bearing capacity of the roof can be improved through the multiple end top stand columns.

Description

technical field [0001] The invention relates to the technical field of high-speed rail, in particular to a high-speed rail roof structure. Background technique [0002] High-speed rail and high-speed trains refer to locomotives or carriages that have driving devices and can generate a certain amount of traction running on the track. There are two types of locomotives. One is a single-section locomotive, which is only responsible for vehicle traction and does not have a carrying function; the other is The power carriage not only has traction capacity, but also has a carrying function, which can transport passengers or goods on the vehicle. [0003] Chinese Patent No. CN211139320U provides a roof structure for high-speed EMU trains, including a high roof and a flat roof. The T-shaped curved profile of the backrest, the T-shaped curved section is consistent with the roof profile, and the hollow cavity of the roof is closed at the end, and its own welded backrest realizes the c...
