Railway hopper car with large-volume movable end wall

Abstract

The invention discloses a railway hopper car with a large-volume movable end wall. According to the technical scheme, the hopper car comprises a vehicle body, a brake device, coupler buffer devices and bogies, and the vehicle body comprises a bottom frame, side walls arranged at the front end and the rear end of the bottom frame respectively, end walls arranged at the left end and the right end ofthe bottom frame, a discharging opening formed in the middle of the bottom frame and a bottom door device matched with the discharging opening. The discharging opening is formed between the two bogies; any end wall comprises a first end plate obliquely matched with the discharging opening end and a second end plate perpendicularly arranged at the upper end of the first end plate, the side portionof the lower end of the first end plate is connected with the bottom frame in a pin joint mode, and a lifting device is arranged between the first end plate and the bottom frame and connected to a control valve. The invention aims to provide the railway hopper car which achieves a large volume through the movable end wall structure, so that the unloading rate of the car is ensured, and the comprehensive transportation capacity of the car is improved.

Description

technical field [0001] The invention relates to a railway hopper wagon, more specifically, it relates to a railway hopper wagon with a larger volume obtained through a movable end wall. Background technique [0002] As an important equipment for railway bulk (such as coal, ore, etc.) cargo transportation, railway hopper wagons adopt the method of loading at the top and unloading at the bottom, which has the advantages of high loading and unloading efficiency and less investment in infrastructure, so it has a large holdings. [0003] However, according to the unloading characteristics of the railway hopper car, in order to ensure the fluidity of the bulk cargo in the car when unloading at the bottom, the end wall of the car generally needs to be inclined at a certain angle, which is greater than the angle of repose of the goods transported in the car. Take the funnel car as an example, the end wall generally has an inclination angle of 40°~50°. As a result, the space under ...

AI Technical Summary

Problems solved by technology

As a result, the space under the end wall cannot be used for loading goods, the space utilization rate is low, the volume of the vehicle is small, and the load is low, especially when transporting small-density goods, the phenomenon of under-tonning is common.
