Steel structure of large axle load generator car body

Abstract

The invention relates to a large-axle-weight power-generating vehicle body steel structure. The large-axle-weight power-generating vehicle body steel structure is of a thin-wall cylindrical structure formed by welding a base frame steel structure, a side wall steel structure, a vehicle top steel structure and an end wall steel structure. A base frame beam, a side wall stand column and a vehicle top camber beam are welded to form a closed annular structure. According to the large-axle-weight power-generating vehicle body steel structure, a middle-beam-free and thin-wall cylindrical whole is adopted in the whole structure to bear a welding structure, the design of reinforcing the vehicle top camber beam, a side wall board, the stand column, a base frame sleeper beam, a beam and the like is performed, and the base frame beam, the side wall stand column and the vehicle top camber beam are designed to be of the closed annular structure. The deformation resistance performance and the torsion resistance performance of the vehicle body structure are ensured, and the strength and the rigidity of the vehicle body structure are improved.

Description

technical field [0001] The invention relates to a car body structure, in particular to a steel structure of a car body of a generator car with a large axle load and no center beam developed for plateau climate, and belongs to the field of mechanical manufacturing. Background technique [0002] Before the large-axle load (over 23 tons) power generation vehicles were put into operation, domestically operated power generation vehicles were used in low-altitude, oxygen-rich areas, and the operation of the generator sets was not limited by the oxygen content of the air. The power generated under operation can meet the power consumption of lighting, air conditioning and other equipment of the whole train, and the power requirement of the generator set is not high. In addition, the train runs a short distance between stations, and the fuel tank can be refueled at each station, so the volume requirement of the fuel tank under the generator car is not strict. [0003] The large axle...

AI Technical Summary

Problems solved by technology

Compared with this kind of railway operating conditions, if ordinary generator cars operate on plateaus, there are the following defects: a) The generator set cannot work at full power, and the power generation capacity is insufficient to meet the electricity requirements of the train; b) The distance between the line stations is long, and ordinary power generation The amount of fuel on board cannot meet the long-distance demand; c) Compared with low-altitude passenger cars, railway passenger cars have added equipment such as oxygen generators, and increased the power of passenger car air-conditioning units, which consumes a lot of electricity

[0004] The use of high-power generator sets has the problems of heavy weight of a single generator set and large size of the unit itself, and in order to meet the long distance between stations, it is necessary to configure a large fuel tank for the generator set

In addition, a large generator set needs to be equipped with a high-power cooling tower, which has a large size and a large weight, which have a great impact on the strength and rigidity of the steel structure of the generator car body.
