Traction and bolster center plate structure of railway tank car

Abstract

The invention provides a traction and bolster center plate structure of a railway tank car. The center plate structure is arranged between two traction beams of the tank car. Each traction beam comprises an upright traction beam web and a horizontal traction beam lower wing surface. The center plate structure comprises a center plate seat which is connected with the traction beam lower wing surface. The center plate seat comprises a center plate seat bottom plate. One end of a bolster beam web, which is connected with the traction beam web, is arranged on the center plate seat bottom plate. The center plate seat bottom plate, the traction beam lower wing surface and a bolster beam are arranged in the same plane, and the center plate seat bottom plate and the traction beam lower wing surface are an integral whole. Since an upper center plate is installed an integral single-layer steel plate, i.e. the center plate seat bottom plate, and the center plate seat bottom plate and the traction beam lower wing surface are integrated, the center plate seat bottom plate and the traction beam lower wing surface are of an integral body, the traction and bolster center plate structure of the railway tank car solves the problems that a middle cover plate under a bolster cannot be in fully close contact with an installation surface, a gap exists and the middle cover plate under the bolster and the upper center plate are in a bad stressed condition and are even cracked in the existing multilayer structure.

Description

technical field [0001] The invention relates to a pull pillow of a railway tank car, in particular to a core plate structure of the pull pillow. Background technique [0002] The railway tank car without center beam is the most important form of railway tank car. The lead sleeper is the main bearing structure of the railway tank car without center beam, which plays the role of supporting the tank body and transmitting the longitudinal force of the train. The lead sleeper is mainly composed of a traction beam along the longitudinal direction of the vehicle and a sleeper beam along the lateral direction of the vehicle. Above the core plate is the key part of the bolster, where the vertical welding seam connecting the traction beam and the bolster and the fixing structure of the upper core plate are located. [0003] At present, the structure of the lead pillow above the core plate of most railway tank cars is as follows: the upper core plate fixing structure includes the cor...

Problems solved by technology

[0007] In order to solve the technical problems existing in the background technology, the present invention proposes a railway tank car pull pillow center plate structure. The integration of the lower airfoil avoids that in the existing multi-layer structure, the middle cover plate under the pillow and the installation surface cannot be completely bonded, and there is a gap, which makes the middle cover plate under the pillow and the upper center plate under stress or even cracked.
