Background technique

Self-unloading cars are usually used in bulk cargo transport. The unloading doors are located at the bottom of the car. After the unloading doors are opened, the cargo is unloaded under the action of its own gravity. In the rail transportation of coal, a dump truck is usually used, the upper part of the compartment is open for loading, and the unloading door is located at the bottom of the compartment, and is unloaded by the gravity of the cargo itself.

Please refer to FIG. 1 and FIG. 2, FIG. 1 is a schematic structural view of a typical self-unloading type car, and FIG. 2 is a three-dimensional structure diagram of the self-unloading type car shown in FIG.

The box body of the carriage is mounted on the longitudinal center beam 7, the ends of the box body are inclined end walls 1, and the end wall 1 extends to the lower side of the longitudinal center beam 7; the interior of the box body is divided into a plurality of unloading by the partition 2 In the region, both sides of the lower end of each partition 2 are provided with guide plates 3 which extend to the longitudinal center beam 7, and a discharge door 4 is provided at the bottom of each unloading area. The unloading door 4 is controlled by the unloading door mechanism 5, and the unloading door 4 swings downward when it is opened, and the unloading door 4 is opened to maintain a certain distance from the lower rail.

The unloading area located in the middle of the box body has a partition plate 2 at both ends thereof, and a beam 6 is arranged on the lower side of the longitudinal middle beam 7 in the middle of the unloading area, and the guide plate 3 on the lower side of the partition plate 2 on both sides of the beam 6 and the two ends Two funnel-shaped regions are formed, and the unloading door 4 is mounted between the cross member 6 and the guide plate 2 at the lower portion of the funnel shape.

One end of the end unloading area of the box is the end wall 1 and the other end is the partition 2, and the end wall 1 is extended. Extending to the lower side of the longitudinal center beam 7, the end wall 1 and the guide plate 3 at the lower end of the partition 2 form a funnel-shaped area, and the unloading door 4 is installed between the end wall 1 and the guide plate 3 at the lower portion of the funnel shape.
