A tread cleaner self-protection control device and method

Abstract

The invention discloses a self-protection control device and a self-protection control method for a tread cleaner. The self-protection control device comprises a hand-operated self-resetting switch connected with a high-level port of a power supply, a time-delay relay connected with the hand-operated self-resetting switch and used for enabling the tread cleaner to be applied continuously and to be switched off after the electrified time of the tread cleaner exceeds the preset time, a digital input module connected with a pressure relay and a low-level port of the power supply and used for detecting the low level after the time-delay relay is switched off, transmitting the lower level to a vehicle control module (VCM) and further relieving the tread cleaner, a switch connected with the time-delay relay, the pressure relay connected with an indicator light and the high-level port of the power supply, and the indicator light connected with the pressure relay and the switch; and thus, the self-protection control device can be used for achieving the protective function on the locomotive tread cleaner, preventing excessive watt consumption due to unreasonable applying time of the locomotive tread cleaner and prolonging the service life of the tread cleaner.

Description

technical field [0001] The invention relates to the field of electrical control of locomotives, in particular to a self-protection control device and method for a tread cleaner. Background technique [0002] At present, some domestic locomotives are equipped with tread cleaners. During operation, the locomotive is affected by external factors such as rain, frost, snow, sand, dust, and oil, and the tread of the wheel is easily polluted, so that the adhesion coefficient will decrease in a large range. Through the action of the brake shoe of the tread cleaner Close to the wheel tread, eliminate pollutants, restore the adhesion coefficient of the locomotive, and prevent the locomotive from skidding and insufficient traction when braking. [0003] In the prior art, when the motorcycle tread cleaner is applied, the non-self-resetting switch on the driver's cab console outputs a high-level control relay, thereby driving the solenoid valve to attract and conduct the air pipeline to...

AI Technical Summary

Problems solved by technology

This control method will cause the driver to release the tread cleaner later, resulting in excessive consumption of the brake shoes of the tread cleaner, which will reduce the service life of the tread cleaner, and even scratch the wheel tread, thereby reducing the safety factor of the locomotive, and there are safety hazards in the operation of the locomotive. And contrary to the original intention of setting up the motorcycle tread cleaner, it can be seen that the electrical control method of the motorcycle tread cleaner lacks the protection of the tread cleaner
