Description

Technical Field

[0001] The present invention relates to the technical field of railway freight cars, and more particularly to the technical field of a connecting device between a center beam and a bottom door of a grain car. Background Art

[0002] Hopper cars can be divided into two types based on their structure: covered and uncovered. Railway hopper cars are both covered and uncovered for transporting cold materials. To meet production needs, metallurgical and coking enterprises also have hopper cars for transporting hot materials, such as quenching cars, hot sintering ore cars, and hopper-type weighing cars. Regardless of the type of unloading hopper car, their common feature is that, to allow the cargo to slide down and be discharged under its own weight, the car body is equipped with a hopper plate at a certain angle to the horizontal, and the unloading door is located at the bottom or side of the car body. Existing patents disclose the following technologies: The patent with publication number CN111547083A and patent name "A Railway Hopper Car with Large Volume and Movable End Walls" discloses the following content: A railway hopper car with large volume and movable end walls, the technical solution of which includes a car body, a braking device, a coupler buffer device and a bogie. The car body includes a chassis, side walls respectively arranged at the front and rear ends of the chassis, end walls arranged at the left and right ends of the chassis, a discharge opening arranged in the middle of the chassis and a bottom door device that matches the discharge opening. The discharge opening is arranged between the two bogies. Any of the end walls includes a first end plate that is inclined to match the discharge opening end and a second end plate that is vertically arranged at the upper end of the first end plate. The lower end side of the first end plate is pin-connected to the chassis. A lifting device is provided between the first end plate and the chassis, and the lifting device is connected to a control valve. One of the purposes of the present invention is to provide a railway hopper car with a large volume obtained by a movable end wall structure, thereby ensuring the vehicle's unloading rate and improving the vehicle's comprehensive transportation capacity.

[0003] The aforementioned patent and current grain hopper vehicles lack a through-beam. The hopper is positioned along the longitudinal centerline of the vehicle, with all four sides extending downward at a predetermined angle. The hopper opening is connected to the bottom door. Grain hopper vehicles with a through-beam have hopper openings located on either side of the beam. Due to the high beam and low bottom door, a connection device between the beam and the bottom door is required. However, a mature solution for this connection has yet to be developed.
