End wall structure and hopper car with same

Abstract

The invention provides an end wall structure of a hopper car. The end wall structure comprises a variable-angle end plate, an upper end beam and at least three transverse bands. The end plate is obliquely arranged; the upper end of the end plate is connected with the upper end beam; two first struts which are symmetrical with each other about the center of an end wall are arranged between the upper end beam and the transverse band closest to the upper end beam and are connected with the transverse band; the two first struts are connected with the end plate; two diagonal bracings which are symmetrical with each other about the center of the end wall are arranged on the lower side of the transverse band closest to the upper end beam; the two diagonal bracings are respectively connected with each transverse band and the end plate; two support plates which are symmetrical with each other about the center of the end wall are arranged on the lower side of the transverse band positioned in the middle of the end plate and are connected with the transverse band; second struts which are symmetrical with each other about the center of the end wall are arranged on the lower side of the transverse band closest to the bottom of the end plate, are connected with the transverse band and are further connected with the end plate. The invention further provides the hopper car with the end wall structure. The end wall structure and the hopper car with the end wall structure have the advantage of capability of bearing high longitudinal impact loads and vertical loads.

Description

technical field [0001] The invention relates to the technical field of end wall structures, in particular to an end wall structure of a hopper car and a hopper car using the end wall structure. Background technique [0002] With the rapid and sustainable development of my country's economy, the demand for coal in many large coal-fired power plants and iron and steel enterprises has been increasing year by year, so the requirements for coal transportation have also been increased accordingly; The transportation tool has huge advantages in terms of economy, transportation volume and mobility, making the hopper car the main tool for coal transportation. The main features of the hopper car are: the end wall of the hopper car body is inclined inward or the end surface is in the shape of a large arc, and then a funnel is installed at the bottom of the car body, and coal, ore, cement and other bulk goods are loaded and unloaded from the top of the car body. At the same time, the bo...

AI Technical Summary

Problems solved by technology

[0003] The body of a railway coal hopper car is basically composed of an underframe group, side walls, and end walls. However, the known end wall structures are difficult to withstand large longitudinal impact loads (for example, in the process of transporting coal by hopper cars, Braking, starting, turning, acceleration and deceleration operations are often performed on the hopper car, and these operations will generate large longitudinal impact loads) and vertical loads, which cannot well meet the actual transportation requirements
