A light-weight gondola car for ore transportation

Abstract

A lightweight open wagon special for transporting ores comprises a wagon body steel structure, a wagon hook buffer device, a steering frame and a brake device. The wagon body steel structure comprises a bottom frame, lateral walls and an end wall. The bottom frame comprises a tail device mounting seat, an auxiliary crossbeam, an auxiliary longitudinal beam, a sleeper beam, a middle beam, a large crossbeam, a small crossbeam and a steel floor. The bottom frame without an end beam and a lateral beam, the lateral walls and the end wall are connected through integral full-steel welding to form an integral stress frame structure. Slag-preventing plates are disposed at the connection of the end wall and a lateral wall, the connection of the end wall of the bottom frame and the connection of the lateral wall of the bottom frame. The lightweight open wagon has the advantages that the end beam and the lateral beam of the bottom frame of a traditional open wagon are omitted, weight of the open wagon is effectively lowered while load capacity of the same is increased, the main bearing part of the wagon body is made of high-strength weather-resisting steel, strength margin and corrosion resistance of the parts of the open wagon are increased, and the service life of the open wagon is prolonged; wagon hooks conforming to AAR standards and a large-capacity rubber buffer are utilized to effectively increase the impact load bearing capacity of the open wagon.

Description

[0001] Technical field: [0002] The invention belongs to the field of mechanical design and manufacture, in particular to the field of railway transportation equipment, in particular to a special gondola car for railway transportation of ore, in particular to a light-weight special gondola car for ore transportation. [0003] Background technique: [0004] Due to the great differences in national conditions, railway road conditions, and railway vehicle transportation equipment in various countries in the world, the application conditions of railway freight cars are very different, especially in some African countries, the railway transportation equipment is very backward, and the overall structural stress of the vehicle is generally unsatisfactory. , Short service life of vehicles, insufficient rigidity and strength reserves, etc., cannot give full play to the role of railway transportation equipment, so that users can obtain the best economic benefits.
