Method and equipment for soldering anti-rust conductive metal on steel rail surface

Abstract

The invention belongs to a method and a device for welding antirust conductive metals on railway steel rail surfaces; wherein, the method includes the steps of rust moving, preheating, welding and slow cooling; the device comprises a vehicle body, a heating device, a swinging welding device and a slow cooling device. The invention can put an end to the misreport problem of a signal system owing to the rust grown on the rail surfaces to lead a signal interlocking system to obtain the reliable information; the device used in the method can effectively weld the antirust conductive metals on the railway steel rail surfaces and has the advantages of simple structure, fast construction speed and good application effect without affecting the inner quality of the steel rails.

Description

technical field [0001] The invention relates to a method and equipment for welding anti-rust and corrosion-resistant conductive metal on the rail surface of a railway rail. Background technique [0002] In the railway signal electric centralized station or the section block system, two steel rails are used as conductors to transmit the signal information of the track circuit. When the train or vehicle is in the track circuit section, a short circuit is formed between the two rails, and the operating voltage of the track relay in the track circuit decreases, so that the track relay falls, and the signal interlocking system knows that there is a fault in this section. car occupied. To ensure that the section can no longer enter the vehicle. Therefore, the track circuit is the signal equipment for the signal system to ensure safety. However, in some special sections in the station, such as the crossing line or side line at the entry end of the double-track section, because t...

AI Technical Summary

Problems solved by technology

However, in some special sections in the station, such as the crossing line or side line at the entry end of the double-track section, because the track does not run for a long time, the track surface is rusted, resulting in poor track circuit shunting, and the signal system cannot distinguish Whether there is a car in this section, even if there are trains or vehicles parked in this section of track, the signal system cannot display

In this way, unsafe factors in railway transportation are formed, which can easily cause serious accidents.

For this reason, it is necessary to carry out frequent inspections on the railway. When the voltage of the track relay is greater than a certain value after the standard shunt circuit breaker is used for testing, it means that the track circuit cannot be used reliably, so it can only be stopped before there is no improvement. Using this track circuit, affects the transportation efficiency
