Side wall assembly of open wagon special for railway ore

Abstract

The invention relates to a side wall assembly of an open wagon special for railway ore. The side wall assembly comprises a side wall plate and a plurality of side columns. Each side column is a quadrangle which is of a variable cross section structure with the longitudinal cross section being gradually increased from top to bottom, the edge of each quadrangle is a right-angle edge, the other edge of each quadrangle is a bevel edge, and the inclination angle of each bevel edge is 3-30 degrees. The end face of the side wall plate is welded to the bevel edges of the side columns, and an upper side beam is vertically fixed to the top end of the end face of the side wall plate. Two pillow columns are further fixed to the two ends of the side wall plate, and the structure of the pillow columns is the same as the structure of the side columns. The side wall assembly further comprises two lower side door assemblies, and the lower side door assemblies are fixed to the side wall plate through the two side columns. The side wall assembly is novel in appearance, low in self weight and firm in structure, all the parts are reliably connected, and the corrugated appearance of the side wall plate is novel; the compression side columns with the variable cross sections can effectively lower the self weight of a side wall, the rigidity of the side wall can be effectively enhanced, and deformation at the position of a lower side door is prevented; transverse bands and end wall transverse bands are connected reliably, a door beam and the lower side door are connected reliably, and the lower side door and a locking mechanism are connected reliably.

Description

technical field [0001] The invention relates to a railway gondola car body, in particular to a side wall assembly of a special gondola car for railway ore. Background technique [0002] The railway gondola car body is mainly composed of an underframe, one end wall, two end walls, lower side doors and side walls on both sides. The steel structure of the car body bears the total vertical load, longitudinal force, lateral force, torsional load acting on the car body and the load when the dumper unloads bulk cargo. Among them, the lateral force, especially the pressure of the bulk cargo on the side wall, has a great influence on the local structure of the car body, which can cause the side column to bend and deform, and aggravate the bending effect of each component of the side wall. The ore gondola car has a higher density than other bulk cargoes, and the same load requires less volume, but the pressure on the side wall is greater. Therefore, the structure, strength and other...

AI Technical Summary

Problems solved by technology

[0003] The side walls of gondola cars currently in use mainly adopt side wall panels perpendicular to the underframe, without lower side doors or lower side door hole plates flush with side wall panels. In the prior art, the following problems are likely to exist: 1. The vertical structure of the wall panel and the bottom frame is easy to form cargo accumulation at the root; 2. The structure without the lower side door is only suitable for the work area where the dumper is used to unload the cargo, and is not suitable for other cleaning such as chain bucket unloaders and manual cleaning. Way

3. The lower side door hole plate is flush with the side wall plate. When the matching lower side door hasp mechanism is installed on the lower side beam, it is only applicable to the chassis structure with lower side beams. The heavy solution is not applicable; when the matching lower side door hasp mechanism is installed on the side wall panel, the door hole is higher than the floor surface, which is not convenient for the cleaning of residual goods
