Anti-deformation supporting device for open-type draw beam of railway flat car

Abstract

An anti-deformation support device for an open-ended draw beam of a railway flat car, comprising a support base and a support plate. The surface is in contact with the lower cover plate of the traction beam, and the supporting seat body is connected with the lower cover plate of the traction beam through the connection hole. After assembly, the boss is located between the web of the traction beam and the lower cover of the traction beam, and is not in contact with the web of the traction beam and the lower cover of the traction beam. Full contact. The invention can not only reduce the deformation of the end beam and the draw beam of the special railway flat car, but also strengthen the strength and rigidity of the end beam and the draw beam structure, and the boss of the support seat does not wear out and does not need to be repaired, and only needs to be worn out in long-term use After the support plate, when there is a gap between the support plate and the web of the traction beam and the facade of the lower cover plate of the traction beam, just replace the support plate, and the operation is convenient and simple.

Description

technical field [0001] The invention relates to a railway wagon structure and device, in particular to an anti-deformation supporting device for an open-ended draw beam of a railway flat car. Background technique [0002] With the advancement of economy and technology, railway freight cars are gradually developing towards specialization. Especially in recent years, container transportation has become more and more common, and the demand for railway container transportation vehicles has also increased. Due to its inherent characteristics—concentrated load conditions, container transportation The structural design requirements for container transport vehicles are relatively high. Especially for special-purpose container flat cars, the container loading platform at the end belongs to the cantilever structure. Due to the height limit of the drawing beam, the section height of the transverse beam at the end is generally small. Under the condition of large concentrated load, the ...

Problems solved by technology

However, because the support block is attached to the existing impact seat, the connection method is limited by the impact seat body, which is not flexible enough; secondly, because the width of the support block is fixed, the width between the web of the traction beam and the lower cover plate is due to manufacturing factors. A group of traction beams are all different, and the adaptability of the support block on this impact seat is not strong; moreover, the anti-cut nail riveted impact seat is formed by an integrated casting process. If the height of the traction beam changes, the mold of the support block part needs Adjustment, lack of versatility, and likely to increase manufacturing costs; finally, because the support block is attached to the existing impact seat and the width of the support block is fixed, if the support block is worn out after long-term use, if the entire impact seat is not replaced, the support block may lose its effect
