Method and equipment for brush plating conductive metal on railway rail surface

Abstract

The invention relates to a method and equipment for brush-plating a conductive metal on a steel rail surface of a railway. The method comprises the steps of rust removal, electric cleaning, activation, brush plating of a conductive bottom layer and brush plating of a wear-resistant antirust top layer. The equipment comprises a vehicle body, a rotary device frame and a rotary device. Through the invention, the problem of system false alarm caused by rust on a rail surface or loose contact can be avoided so that a signal interlocking system can obtain reliable information; the method has the advantages of simplicity and practicability, fast construction, low cost and no influence on inherent quality of a steel rail; and the equipment adopted by the method can effectively brush-plate an antirust conductive metal on the steel rail surface of the railway, and has the advantages of simple structure, reliable work, firm brush plating and good using effect.

Description

Technical field [0001] The invention relates to a method and equipment for brush-plating conductive metal on the rail surface of a railway. Background technique [0002] In the railway signal electrical centralized station or section blocking system, two steel rails are used as conductors to transmit the signal information of the track circuit. When a 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 is reduced, so that the track relay will fall. The signal interlocking system knows that the section has Car occupation. To ensure that this section can no longer enter the vehicle. Therefore, the track circuit is the signal equipment to ensure the safety of the signal system. However, in some special sections of the station, such as the crossover or the side line at the inbound end of the double track section, the track surface is long rusted due to the long time tha...

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
