Railway wagon and side wall thereof

Abstract

The invention provides a railway wagon and a side wall thereof. The structure is simple, the manufacturing difficulty is low, required parts are less, the strength and the stiffness are high, and the use reliability is good. The side wall comprises a plurality of wall separating plates which are connected from left to right in turn; every wall separating plate comprises an inner lateral plate and an outer lateral plate which extend upward in the vertical direction; every inner lateral plate and the corresponding outer lateral plate are connected with each other; a hollow chamber is formed between every inner lateral plate and the corresponding outer lateral plate; reinforcing ribs are arranged in every hollow chamber. Compared with the prior art, a supporting beam which is of a slab-column structure is cancelled and accordingly the number of parts is reduced, the structure of the side wall is simplified, and the manufacturing difficulty of the side wall is reduced; every wall separating plate is formed by the inner lateral plate and the outer lateral plate through connection, the reinforcing ribs are added between every inner lateral plate and the corresponding outer lateral plate to form a closed box structure, and accordingly the strength and stiffness performance is good and the safety and the reliability of the railway wagon during usage are improved; the structure of every wall separating plate can be adjusted according to needs and accordingly the structural self-weight is reduced and the lightweight railway wagon is implemented.

Description

technical field [0001] The invention relates to the technical field of railway transportation, in particular to a railway freight car and an end wall thereof. Background technique [0002] The funnel car is a kind of railway freight car, which has the advantages of high unloading efficiency, low comprehensive investment, low daily operating costs, and good working conditions. It is the most economical transportation method to transport bulk bulk goods such as coal by using the funnel car. The consensus of domestic and foreign railway transportation companies; especially the lines that are close to the mining area, have a large transportation volume, and have fixed coal transportation sections, the economic effect of transportation is more obvious. [0003] The bottom of the vehicle between two adjacent bogies of the hopper car is provided with an unloading funnel. After the unloading bottom door is opened, the bulk cargo loaded in the car will fall and converge by the gravit...
