Side wall of body of ore open wagon for railway

Abstract

The invention discloses a side wall of a body of an ore open wagon for a railway. The side wall mainly consists of an upper side beam, a built-in pillar, a built-in side pillar and a side wall plate. The upper side beam is integrally pressed by an outer turnup plate, an upper plane plate, an inner bevel plate and a lower vertical plate which are made of stainless steel. The inner bevel plate and the lower vertical plate are welded with opening edges of the built-in pillar and the built-in side pillar in corresponding positions. The side wall plate is integrally pressed by a top overlapping plate, an upper inner inclined plate, a lower outer inclined plate, an arc-shaped transitional plate and a bottom horizontal plate which are made of stainless steel. Both ends of the plates are welded with the opening edges of the built-in pillar and the built-in side pillar in corresponding positions. The top overlapping plate is welded with the bottom end of the lower vertical plate, and the bottom horizontal plate is welded with floor on the chassis. The side wall provided by the invention is simple in structure, light in self weight, high in strength and rigidity and good in integral assembly process, and the conveying capacity can be effectively improved, and the requirement of light weight and heavy load of a large axle load open wagon for the railway can be met.

Description

technical field [0001] The invention relates to a railway gondola car carrying ore, coal, building materials and other bulk goods, in particular to a side wall of a railway ore gondola car body. Background technique [0002] The railway open car is the main vehicle in railway transportation. It has the largest number of existing railway wagons. It mainly undertakes the task of transporting bulk goods such as coal, ore, mining materials, timber, and steel. It can also be used to transport some Heavy machinery and equipment. Railway gondola cars can be divided into two categories according to different unloading methods: one is the gondola car suitable for manual or mechanical loading and unloading operations, and the other is suitable for large-scale industrial and mining enterprises, stations, and wharves for fixed grouping transportation between large industrial and mining enterprises, and using a dumper. Unloading gondola. [0003] With the development of railway freight...

AI Technical Summary

Problems solved by technology

But this design has the following defects: First, the number of various thickened and widened profile parts forming the side wall is large and the structure is heavy, which will inevitably increase the weight of the side wall. The size parameters of the ore car also need to be increased accordingly, which will lead to a substantial increase in the weight of the ore gondola car

Second, the side walls are generally equipped with lower side doors and middle doors for loading and unloading goods and personnel entry and exit. The lower side doors and middle doors also need to be equipped with corresponding opening and locking devices. All door frames, door panels and their accessories need Welding and / or installing to the side wall leads to complex structure, various processes, low manufacturing efficiency, high labor intensity of workers, especially increases the difficulty of its connection with the end wall, chassis, etc., which is not conducive to improving the assembly of the entire car body Craftsmanship

Third, due to the large number and different shapes of the components of the side wall, moisture corrosion is prone to occur at the welded section, especially at the lower side door and the middle door. The oxidation and corrosion phenomenon is the most serious, so its service life is relatively short and maintenance Maintenance is more frequent, which increases the manufacturing and operating costs of railway ore open car
