Abstract

The invention discloses a railway vehicle, comprising a car body and a top cover, wherein the top cover comprises two cover plates; the two cover plates are respectively rotatably connected with the car body, so that the two cover plates can be close to each other or far away from each other, so that the top cover can be closed or opened; and the top of the two cover plates are provided with a triggering member; Further comprising an opening and closing assembly respectively cooperating with the two triggers, The opening and closing assembly is directly or indirectly fixed to the ground, and comprises a bracket and a track fixed on the bracket. The distance between the two tracks is gradually changed in the longitudinal direction. When the railway vehicle is traveling, the triggering member can move from the inner end part of the track to the outer end part, and can also move from the outer end part of the track to the inner end part, and the cover plate is driven to rotate to open orclose the top cover. The opening and closing of the top cover are automatically triggered by the running of the railway vehicle without additional driving device, which saves the cost, improves the opening and closing efficiency, simplifies the structure of the railway vehicle, lightens the overall weight of the vehicle, reduces the cost and improves the versatility.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to railway vehicles. Background technique [0002] The loading port of the railway coal truck has an open rectangular structure. During the transportation process, due to the high speed of the vehicle itself and the action of the wind, dust and other phenomena will occur. Not only the coal transportation on the vehicle is lost, and the economic benefit is reduced, but also, the environment is greatly polluted. At present, in order to reduce the phenomenon of dust, each coal transportation organization installs a movable roof on the loading port of the vehicle. When loading and unloading, the roof is opened, and the roof is closed during transportation. Thereby, the generation of dust phenomenon is prevented. [0003] In the prior art, the opening and closing of the movable roof of the truck can be realized by installing a power and transmission mechanism on each vehi...
