Railway wagon body

Abstract

The invention discloses a railway wagon body. The railway wagon body is an integral bearing type wagon body formed by combined welding of an underframe, side walls and end walls and of a full-steel welded skeleton-type structure; the underframe is composed of a middle beam, variable section box-type body bolsters, cross beams, I-shaped cross beams, a floor and the like; each side wall is composedof pillow columns, groove-type side columns, T-shaped side columns, transverse belts, side plates and the like; the middle beam serves as a keel; the underframe and the side walls are connected both horizontally and vertically to form a rib of a skeleton; the keel and the rib bear the longitudinal force and the transverse force correspondingly and do not interfere with each other; and the side walls are inclined, the side columns are arranged externally, and the interior of the wagon body is flat and smooth. The railway wagon body is not provided with devices such as stay bars, partition wallsand side column reinforcing seats of a traditional ore open wagon; the underframe and the side walls are subjected to reinforcing design, and therefore, the wagon body can adapt to the requirement ofa high-frequency car dumper for rapid turnover and unloading, and through the smooth inner surface, goods are prevented from adhering and accordingly being stacked when unloaded, the moving speed ofthe goods is high, the complete-unloading rate is high; and the volume is large, so that the requirement of loading the goods with the small specific weight and large viscosity is met.

Description

technical field [0001] The invention belongs to the technical field of railway freight car vehicle design, and in particular relates to an open car body structure including side walls, end walls, underframes and connecting structures thereof. Background technique [0002] For some railway special gondola cars, the use of dumpers for unloading has the characteristics of high unloading efficiency. For the dumper unloading open car that transports viscous and light goods such as aluminum ore and peat, the inner wall of the vehicle needs to be smooth and there are no protrusions to avoid the accumulation of goods that are difficult to unload. If a mechanical automatic cleaning device is required, the struts and partition walls are not allowed inside the vehicle. Under the above circumstances, the weight and side pressure of the cargo can only be supported by the rigidity and strength of the car body chassis, side walls and end walls themselves, and the connection method between...

AI Technical Summary

Problems solved by technology

In addition, side columns with an inclination angle are generally installed on the upper plane of the bottom frame beam. The problem caused by this is that the deflection of the side wall does not match the deflection of the bottom frame. Each side column needs to be matched and cut during assembly. Low, this problem does not exist if the side wall is attached to the side of the chassis
