Large-opening folding type moving top cover of railway wagon

Abstract

The invention provides a large-opening folding type moving top cover of a railway wagon, which comprises guide rail seats, wherein the guide rail seats are arranged at two sides of the top of the wagon, and each guide rail seat comprises a plurality of guide rails; a plurality of top plates, wherein two sides of each top plate are arranged in the corresponding guide rails in a sliding manner, andblocking irons are arranged at two ends of each top plate; a transmission part, wherein the transmission part comprises a hoisting pulley, a steel wire rope and a driving device, one end of the hoisting pulley is connected with the guide rail seats, the driving device is arranged at the end part of the railway wagon, the steel wire rope is wound on the hoisting pulley and the output shaft of the driving device, an enclosed winding is formed, a stop block is arranged on the steel wire rope, the driving device drives the steel wire rope to rotate, and the stop block can be contacted with the stop iron to drive the plurality of top plates to fold or unfold. The large-opening folding type moving top cover of the railway wagon is large in opening degree, small in opening and closing occupied space and strong in rigidity.

Description

technical field [0001] The invention belongs to the field of trains, and more specifically relates to a large-opening foldable movable roof of a railway wagon. Background technique [0002] Most of the movable roofs of existing railway freight cars have small openings, which have high requirements for loading facilities, cannot adapt to large-width loading ports, and reduce the loading efficiency of vehicles. However, some existing movable roofs with large openings have the problem of occupying a large space during the opening and closing process and after the roof is opened, intruding into vehicles and even building boundaries, which limits the use of vehicles. At the same time, due to the large span of the roof, The lack of support in the middle leads to heavy weight and poor rigidity of the top cover. [0003] Therefore, it is necessary to develop a large-opening foldable railway wagon movable roof with large opening, small opening and closing space, and strong rigidity....
