Title:
RAILWAY OPEN WAGON AND SIDE WALL THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/105116
Kind Code:
A1
Abstract:
A railway open wagon and a side wall thereof, the side wall comprising sleeper columns (1), side columns (2), and side panels (4) distributed at intervals along the direction of length thereof, the side panels (4) being fixedly connected between adjacent side columns (2) and adjacent side columns (2) and sleeper columns (1), and also comprising wear plates (6) used for preventing the sleeper columns (1), the side columns (2), and the side panels (4) from being directly worn, the side panels (4) being curved panels having a top part and a bottom part bending inward and a middle part protruding outward. The present structure does not require the addition of other parts to increase rigidity, and has sufficient lateral rigidity; as the bottom part of the side panel (4) bends inward, a bottom panel (7) connected to the bottom part of the side panel can be set to a narrow width without changing the volume of the railway open wagon; thus, the side wall (4) has sufficient lateral rigidity and can satisfy the demands for lightening the weight of a railway open wagon.
