Train sliding viscosity increasing method and device

Abstract

The embodiment of the invention discloses a train sliding viscosity increasing method and device.The method comprises the steps that the sliding degree and actual utilization adhesion of each train in a target network segment of a train are obtained, the train is divided into at least two network segments, each network segment comprises at least one train, and a sanding device is arranged on one train in each network segment; judging whether the target network segment meets a preset sanding tackifying condition or not according to the respective sliding degree of each vehicle in the target network segment and the actual utilization adhesion; if the preset sanding tackifying condition is met, the sanding speed is determined according to the speed of the train; and a sanding instruction is generated according to the sanding speed, and the sanding instruction is sent to a sanding device corresponding to the target network section, so that the sanding device corresponding to the target network section carries out sanding according to the sanding speed. The sand spraying tackifying agent has the beneficial effect of improving the sand spraying tackifying effect of the train.

Description

technical field [0001] The present invention relates to the technical field of sliding thickening of EMUs, in particular to a method and device for sliding thickening of trains. Background technique [0002] When the EMU is running at high speed, if the adhesion between the wheels and the rails is not good enough to slide, it may cause serious scratches on the wheels, and at the same time greatly extend the braking distance, which not only reduces the comfort of the ride, but even endangers the safety of the train, and also affects the steering. Added impact to frame components shortens their life. Adhesion through coasting helps reduce the chance of skidding, prevents wheel scuffing, and shortens braking distances in adverse sticking conditions. [0003] At present, EMUs generally use sand to increase viscosity, but the current spraying method is relatively simple. The vehicle control solenoid valve is fixed for a certain period of time. When the air supply of the sand box...

Problems solved by technology

However, the sliding adhesion of vehicles is time-varying, and the degree of sliding changes in real time. Using a fixed sand output may result in too much or insufficient sand. Excessive sand will cause waste, and excess sand remaining on the track may increase wheel-rail wear. Insufficient sand will not To achieve the purpose of really improving adhesion
