Abstract

The invention provides a heavy-duty rail motor car, relating to a railroad car and aiming at meeting the requirements of special environments in high-cold and high-altitude areas. A transmission system of the heavy-duty rail motor car adopts an alternating-direct current transmission device, a control system adopts a microcomputer constant-power exciting device and a PLC programmable controller, and a main traction generator adopts a power-frequency generating device and a matched power supply device. The two sides of the lower part of a car body are distributed with two axle-type B0-2 two-axle steering frames; each wheel of the steering frame is respectively provided with a lightning-protecting grounding device at one end of a car axle; the car body is internally provided with an oxygen generator and an independent bathroom which is internally provided with a movable portable toilet; a main diesel generator unit adopts an electric heating oil and water-preheating device; and an oil-water pipeline adopts cold-proof wrapping and is provided with an electric hot-mixed device. The heavy-duty rail motor car has fast speed and safe and reliable operation, can well adapt to the severe environment in high-altitude areas and can provide life condition and safe guarantee for drivers and passengers.

Description

technical field [0001] The invention relates to a railway vehicle, in particular to a heavy rail vehicle. Background technique [0002] The Gela section of the Qinghai-Tibet Railway is located in the hinterland of the Qinghai-Tibet Plateau, with a total length of 1142 kilometers, an average altitude of 4500m, and an annual average air pressure of 54.4-62.0kPa, which is 60%-70% of that on the plain; The following is as long as 235-330 days / year, and the extreme minimum temperature is -36℃~-45℃. Most of the railways are uninhabited areas, and most of the stations are unattended. It is the plateau railway with the highest altitude, the longest line and the longest mileage through permafrost in the world. On the Qinghai-Tibet Railway, the track car is not only the key equipment for line maintenance, but also undertakes the important task of line inspection. Its reliable operation is related to the driving safety of the Qinghai-Tibet Railway and is an important guarantee for the...
