Self-dumping box of closed wagon

Abstract

The invention provides a self-unloading carriage for closed type truck, which can be formed by refitting the existing freight car and the box car. The self-unloading carriage is used for transporting bulk commodities on the railway and can also serve as a box car. The invention overcomes the shortcomings of large road loss, much contamination and high gravity center of the transportation with gondola car and is a self unloading carriage for closed type truck with the function of self unloading, no road loss of the freight and lower gravity center.

Description

technical field [0001] The invention relates to a railway freight car, in particular to a closed dump carriage of a freight car. Background technique [0002] In my country's railway cargo transportation, bulk cargo such as coal and ore account for a large proportion. The volume of coal alone reached 1.54 billion tons last year, and a Daqin line transported 300 million tons. This shows that bulk cargo The volume of transportation is large. However, most of these bulk cargoes are now transported by gondola cars. The wind, rain, and man-made theft caused great losses during the transportation. For example, the road loss of coal on the Daqin Line last year exceeded 3 million tons. It exceeded 1.6 billion yuan; secondly, from the perspective of the traditional gondola car structure, the floor of the carriage is higher than the ground, which causes the center of gravity of the vehicle to be unstable and affects the need for speed increase of the railway. Unloading points such as...

However, most of these bulk cargoes are now transported by gondola cars. The wind, rain, and man-made theft caused great losses during the transportation. For example, the road loss of coal on the Daqin Line last year exceeded 3 million tons. It exceeded 1.6 billion yuan; secondly, from the perspective of the traditional gondola car structure, the floor of the carriage is higher than the ground, which causes the center of gravity of the vehicle to be unstable and affects the need for speed increase of the railway. Unloading points such as transfer terminals must also be equipped with large-scale unloading equipment or other unloading facilities such as steering machines, positioning machines, and dumpers. These have increased a lot of equipment investment and unloading costs for the use and transfer of goods; A large amount of coal and other bulk goods lost and accumulated in a year not only waste resources but also pollute the environment. Therefore, the current gondola car transportation of bulk goods such as coal can no longer meet the requirements of the times, and needs to be improved in design
