Description

Technical Field

[0001] The utility model relates to the technical field of railway gondolas, and more specifically to the technical field of a stepped side wall of a railway freight car, which is applicable to a special railway gondola for transporting coke. Background Art

[0002] Limited by vehicle structure, unloading methods and railway clearances, there are various forms of side wall structures for existing railway gondolas in China, but they are generally the same with minor differences, usually being panel-column structures, arc-clad panel structures, and variable cross-section structures. The unloading methods of railway gondolas mainly include manual unloading, excavator unloading and car dumper unloading. Excavator unloading is simple in operation, low in investment cost and strong in adaptability, but has low unloading efficiency. The excavator frequently collides with and scratches the side wall, causing serious damage to the side wall of the car body, greatly increasing the maintenance cost during the vehicle life cycle. Car dumper unloading has high efficiency and no damage to the car body. It is usually indoor unloading operation with little environmental pollution. However, it has high requirements for vehicle strength and stiffness. The vehicle design needs to consider the working conditions of the car dumper. At the same time, the construction investment cost of the car dumper unloading line is high and it is greatly restricted by the site.

[0003] For the existing railway gondolas transporting granular goods, excavator unloading is generally adopted, and there are generally bulges, deformations and damage marks caused by excavator unloading on the side wall panels, and there are generally cases of cutting and repairing. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a stepped side wall of a railway freight car in order to solve the technical problem that the existing side wall panels are prone to bulge, deform and leave damage marks during excavator unloading.

[0005] The utility model specifically adopts the following technical solutions to achieve the above purpose:

[0006] The utility model provides a stepped side wall of a railway freight car, which includes side wall panels, upper side beams arranged at the top of the side wall panels, multiple inner columns arranged at intervals on the inner side of the side wall panels, and outer columns arranged at intervals on the outer side of the side wall panels;

[0007] The side wall panels include upper side panels and lower side panels arranged below the upper side panels. Each outer column is arranged below the upper side panel, and each inner column is welded to the inner sides of the upper side panel and the lower side panel;

[0008] The number of inner columns is the same as that of outer columns, and their positions correspond one by one. The outer columns and the inner columns form a side column structure. The lower side panel is located between the inner columns and the outer columns, showing a sandwich shape, increasing the side column cross-section and improving the anti-bulging ability of the side wall; the stepped side wall panel structure is arranged inside the lower side panel.

[0009] Specifically, the external structure of the upper side plate is adopted, which can make full use of the vehicle gauge width and improve the vehicle volume. By reducing the distance between the inner columns or outer columns and canceling the free surface of the side wall plate at the door hole, the deformation and damage of the door hole can be prevented.

[0010] In one embodiment, the upper side beam is made of cold-formed square steel. The upper side beam is overlapped and fixed or welded to the upper side plate.

[0014] Specifically, only the welding distance is reserved between the side edge of the door hole and the inner column, reducing the freedom degree around the door hole and avoiding damage caused by direct bumping and scraping of the lower side plate when unloading with mechanical facilities.

[0015] In one embodiment, each outer column adopts a cold-formed "hat-shaped" structure, and strengthening ribs are arranged inside each outer column.

[0018] In one embodiment, anti-collision columns are arranged between adjacent two inner columns located on the inner side of the side wall plate.

[0019] Specifically, anti-collision columns are arranged on the inner side of the upper side plate between the two side columns. The anti-collision columns are made of cold-formed channel steel. They are buckled on the inner side of the upper side plate between the two side columns and fixed by welding, which can prevent the mechanical unloading facility from directly colliding with and scraping the upper side plate, and improve the anti-deformation ability of the side plate.

[0020] In one embodiment, the outer plane of the outer side column is aligned with the outer plane of the side wall panel. The upper part of the upper side plate is narrowed inward, showing a broken-line structure. The top of the upper side plate overlaps with the upper side beam. The bottom of the upper side plate is a cold-formed right-angle structure, and the cold-formed right-angle structure is buckled with the lower side plate to form a cold-formed right-angle structure with a closed inner cavity.

[0021] Specifically, the upper side plate is cold-formed from a plate. The upper part of the upper side plate is narrowed inward, showing a broken-line structure, and overlaps with the upper side beam. The lower part is a cold-formed right-angle structure, which is buckled with the lower side plate to form a closed inner cavity, replacing the traditional side wall cross belt, maintaining the stability of the side wall, enhancing the overall stiffness of the side wall, and at the same time reducing the vehicle self-weight. Adopting the external structure of the upper side plate can make full use of the vehicle gauge width and increase the vehicle volume.

[0022] The lower side plate is cold-formed from a plate. The upper part of the lower side plate is bent outward, showing a broken-line structure, and is buckled and welded with the upper side plate. A stepped side wall panel structure with the upper side plate external and the lower side plate internal is realized. The lower side plate is provided with lower side plate holes between the two side columns.
