Description

Technical Field

[0001] The invention belongs to the technical field of railway transportation, and in particular relates to an opening and closing mechanism supporting and connecting device and a covered hopper car. Background Art

[0002] Railway covered hopper cars are specially used for railway transportation of bulk goods to avoid rain and snow. They have two structures: straight plate side walls and arc plate side walls. The arc plate hopper car is jointly borne by the side walls, end walls and chassis to bear vertical and longitudinal loads. In order to improve the rigidity of the side wall panels, a support plate is usually provided, and its lower part is fixed on the back of the chassis. However, the support plate has a large area and a large weight, and the longitudinal load it bears is also large, which reduces the reliability of the connection between the support plate and the side wall. In addition, a loading port and a loading port cover are provided on the top of the car body. When loading, the loading port cover is opened, and the grain is loaded into the car body through the loading port by the unloading chute. After loading, the loading port cover is closed. Most of the existing covered hopper cars have a manually opened top cover, which is composed of several sections of flip-type loading port covers. Each section of the loading port cover can meet the needs of a single person to open and close the operation independently. However, it takes a long time to open and close the loading port cover of a manual open top hopper truck, which affects the transportation efficiency. At the same time, the operator needs to open and close the loading port cover on the roof, and improper operation may cause personal injury to the operator. In order to improve the operating efficiency and the safety of the operator, there is also a pneumatic open top hopper truck, in which the transmission shaft is arranged on the upper part of the roof and the transmission shaft is driven by the cylinder to rotate, so that the top cover can be opened and closed in a short time. However, the transmission shaft occupies the space in the height direction of the vehicle, resulting in a reduction in the loading height inside the vehicle, which is not conducive to increasing the vehicle volume.

[0003] To sum up, how to effectively provide a supporting connection device that can not only significantly enhance the vehicle connection stiffness and reliability, but also make full use of the space inside the vehicle, arrange the drive shaft support seat, and realize the pneumatic opening of the top cover of the hopper car has become a technical problem that needs to be urgently solved by technical personnel in this field.
