Two-side unloading arc wrapper sheet hopper wagon special for railway

Abstract

The invention discloses a two-side unloading arc wrapper sheet hopper wagon special for a railway. The hopper wagon comprises a chassis, and two symmetrically-arranged side walls are arranged on the chassis. Each side wall is of a structure similar to a rectangular board, and the two ends of each rectangular board are recessed inward towards the center position of the rectangular board to form a semicircular concave arc. The two side walls are connected into a whole through two end walls to form a loading space. A hopper is installed in the loading space, the interior of the loading space is divided into four regions through the hopper, the bottom of each of the four regions is provided with a corresponding bottom door, and the four bottom doors are automatically opened or closed through bottom door opening mechanisms.

Description

technical field [0001] The invention relates to a special hopper car for railways, which is used for transporting bulk goods such as coal, in particular to a special hopper car for railways with arc-clad boards for unloading on both sides. Background technique [0002] At present, there are basically two structures of hopper cars for transporting coal on railways: [0003] 1. Unloading on both sides of the track: the hopper car using this unloading method adopts a plate-column structure, that is, the side walls are flat. The biggest disadvantage of this structure is that the car body itself is heavy, and the hopper car loaded with 70 tons of coal has a dead weight of 24 tons, which wastes energy to a certain extent. [0004] 2. Unloading in the middle of the track: the hopper car using this unloading method adopts a circular arc cladding structure. The biggest disadvantage of this unloading method is that it requires high ground facilities, and a deep pit is required in the...

AI Technical Summary

Problems solved by technology

The biggest disadvantage of this structure is that the car body itself is heavy. A hopper car loaded with 70 tons of coal has a dead weight of 24 tons, which wastes energy to a certain extent.

[0004] 2. Unloading in the middle of the track: the hopper car using this unloading method adopts an arc-clad structure. The biggest disadvantage of this unloading method is that it requires high ground facilities, and a deep pit is required in the middle of the track, which requires a large initial investment.
