Special gondola vehicle with a shallow concave bottom for coal transportation

Abstract

A special gondola vehicle with a shallow concave bottom for coal transportation belongs to the transportation facilities, in particular to a railway truck gondola vehicle. The gondola vehicle comprises a vehicle body, a vehicle coupler buffer device, a braking device and a bogie. The vehicle body comprises a chassis, a side wall and an end wall. The key technique is that the chassis comprises a centre sill, a sleeper beam, a lower side beam and an end beam, two downwards concave shallow concave bottoms are arranged between the two sides of the centre sill and between the lower side beam and the sleeper beam in the middle of the side wall, the depths of the shallow concave bottoms are aligned with the lower plane of the centre sill, the side wall comprises a side wall board and a side post, the two ends of the side wall are end door panels which are inwards concave with respect to the side wall board to form stages, so as to form the end door plate with a concave structure. The invention not only effectively increases the vehicle body volume, but also decreases vehicle height of center of gravity, and improves vehicle riding quality.

Description

(1) Technical field: [0001] The utility model relates to a special gondola car for transporting coal with a shallow concave bottom, which belongs to a railway transportation tool, specifically a railway freight car gondola car. (two) background technology: [0002] The special gondola car chassis for railway coal transportation has forms such as flat bottom structure and bathtub structure. With the development of heavy-duty technology, when the height and width of the traditional flat-bottomed vehicles have a small limit, the load can only be increased by increasing the length of the vehicle, which will increase the length of the train formation, and at the same time, it cannot be rolled over with the existing vehicles. machine match. Although the bathtub structure can effectively increase the volume of the vehicle body, it brings a series of disadvantages such as complicated structural stress, difficult braking arrangement, and inconvenient vehicle maintenance and repair. ...
