Abstract

The invention discloses an intelligent variable sand spreading device for railway and urban rail transit trains, which comprises a sand box, a variable sand spreader, an air pressure system, and an intelligent variable sand spreading controller. The sand isplaced in the sand box, the variable sand spreader is arranged at a sand outlet at the bottom of the sand box, the air pressure system is connected with the variable sand spreader.An intelligent variable sand spreading controller is connected with the air pressure system.The variable sand spreader is provided with a sand outlet pipe and a plurality of sand blowing nozzles with different lengths inside.The air outlets of the sand blowing nozzles with different lengths are all aligned with the sand inlet of the sand outlet pipe, and the distance between the sand outlet and the sand inlet is different.The sand outlet pipe extends out of the variable sand spreader and is connected with a nozzle, and the nozzle is arranged in alignment with the contact area of a wheel rail. The intelligent variable sand spreading device for railway and urban rail transit trainshas the advantages of saving sands, achieving the best wheel rail adhesioneffect, preventing the failure of train signal track circuits caused by excessive sands and preventing environmental pollution at the same time.

Description

technical field [0001] The invention relates to the technical field of sand spreading devices, in particular to an intelligent variable sand spreading device for railways and urban rail transit trains. Background technique [0002] As we all know, railway and urban rail transit vehicles rely on the adhesion between the wheel and rail to achieve the traction and braking of the train. In rain, snow, wet weather and natural environments such as fallen leaves, the adhesion between the wheel and rail will be reduced. When the adhesion force required by the train traction and braking is lower than that, the wheels will spin or slide, which will cause scratches on the wheel tread and the top surface of the rail, and affect the normal operation of the train. The common way at home and abroad is to increase the adhesion between the wheel and rail by sprinkling sand on the top surface of the rail, so as to prevent the wheel from idling or sliding, and maintain the normal operation of ...
