Hopper car used to transport powdery goods

Abstract

The invention discloses a hopper car used to transport powdery goods, and relates to railway transportation field. The hopper car includes up-opened car body, bottom door opening and closing mechanism, coupler-draft gear and bogie. The car body consists of two front and rear wall panels, two left and right wall panels and baseplate. A funnel plate is in the interior of the car body. Bottom door opening and closing mechanism consists of upper gear and lower gear. Car top set has dust-proof device, which includes dustproof cup and an electric drive mechanism for achieving dust-proof device opening and closing. This invention has the advantages of being moisture proof and dustproof, simple structure, high discharging efficiency and high drive accuracy. The hopper car fills a gap for depending electric driven in dustproof and discharge.

Description

technical field [0001] The invention relates to the technical field of railway transport vehicles, in particular to a hopper vehicle for transporting powdered goods. Background technique [0002] The self-unloading hopper trucks are all designed with an open mouth. If the goods with fine particles are transported, the environment along the road will be polluted, and the health of the operators will be endangered. Roof, a feed inlet is set on the roof, and a movable cover is set at the feed inlet to realize the purpose of closing the car body, but at this stage, the roof is all arc-shaped, resulting in a relatively limited structure of the movable cover. The movable cover plate controlled by the actuator is affected by the rated pressure of the cylinder and the diameter of the cylinder, so the control accuracy of the movable cover plate is low and the structure is complex.

AI Technical Summary

Problems solved by technology

[0002] The self-unloading hopper trucks are all designed with an open mouth. If the goods with fine particles are transported, the environment along the road will be polluted, and the health of the operators will be endangered. Roof, a feed inlet is set on the roof, and a movable cover is set at the feed inlet to realize the purpose of closing the car body, but at this stage, the roof is all arc-shaped, resulting in a relatively limited structure of the movable cover. The movable cover plate controlled by the actuator is affected by the rated pressure of the cylinder and the diameter of the cylinder, and the control precision of the movable cover plate is low and the structure is complex

[0003] When transporting goods that cannot catch water, the goods will condense due to moisture, which will increase the difficulty of unloading

At present, in addition to the workers knocking on the car box, the labor required to manually loosen the damp goods is reduced by adding a car body vibration device, but this method makes the structure of the hopper car complicated, and the manufacturing cost increases. Improve the unloading effect, the unloading effect is poor

[0004] At present, the brake of the opening and closing mechanism at the bottom of the hopper car basically adopts a combination of pneumatic and manual mechanical rotation devices, which has poor driving accuracy and low unloading efficiency.
