Novel re-railing axle bracket for rail flat car

Abstract

The invention belongs to the technical field of railway rail flat car equipment manufacture, and particularly relates to a novel re-railing axle bracket for a rail flat car. The novel re-railing axle bracket for the rail flat car comprises a car body, a U-shaped supporting ring and an axle, the two ends of the U-shaped supporting ring are fixed on the car body through a first connecting part and a second connecting part correspondingly, and the structures of the first connecting part and the second connecting part are the same; and the first connecting part and the second connecting part both comprise first mounting seats and second mounting seats, the first mounting seats and the second mounting seats are fixedly connected in a surface contact mode, the axle is arranged in the U-shaped supporting ring, and the axle and the U-shaped supporting ring are arranged in a clearance mode. According to the novel re-railing axle bracket for the rail flat car, the slipping phenomenon caused easily in the long-time using process of a traditional type re-railing axle bracket is avoided, and the novel re-railing axle bracket has the characteristics that the contact surface is large, the connecting strength is high, and the novel re-railing axle bracket can be applied to an acidic operating environment.

Description

technical field [0001] The invention belongs to the technical field of railway track flat car equipment manufacturing, and in particular relates to a novel double-rail shaft support for a track flat car. Background technique [0002] Railway is the lifeblood of my country's national economic development. Railway transportation plays a very important role in the transportation of goods. It has the characteristics of strong transportation capacity and loads of goods. In railway transportation, the rail flat car is an important carrier and can be directly used for Transport steel, wood, automobiles, mechanical equipment and other bulky or heavy goods, and other goods can also be transported by means of containers. The rail flat car can also meet the needs of national defense and load various military equipment. Flat cars equipped with movable wall panels can also be used to transport bulk goods such as ore, sand, and gravel. In recent years, with the rapid development of railw...

AI Technical Summary

Problems solved by technology

The traditional double-rail shaft support is composed of three parts: U-shaped support ring, nut and lifting lug. The lifting lug is connected with the flat car body by welding. During the hoisting or rerailing process of the rail flat car, the rerailing shaft support is directly stressed and the load is transmitted to the thread where the U-shaped support ring and the lifting lug are connected. This solution has the following problems: First, the long-term use of the vehicle Among them, due to the direct force of the thread, stress concentration occurs at the threaded hole, which is prone to "slipping" phenomenon, and there are potential safety hazards; second, for some climates with high humidity and acidic environments, U-shaped ring Threads are prone to corrosion, which also creates potential safety hazards when the rerail shaft support is stressed
