Description

technical field [0001] The invention relates to the technical field of trucks, in particular to a roof opening and closing device for a truck. 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 force, 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 preventing the occurrence of dust phenomenon. [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 mecha...
