Abstract

The invention discloses a rail transit sanding system which comprises a material storage barrel, the top of the material storage barrel is designed to be open, a sanding opening is formed in the bottom of the material storage barrel, a sand crushing device is arranged in the material storage barrel, the sand crushing device is provided with a supporting rod, a sand crushing rod is installed in the material storage barrel, and one end of the top of the sand crushing rod extends out of the material storage barrel; a driving device is arranged in the material storage barrel and provided with a mounting plate, and the top of the mounting plate is fixedly connected with a driving motor; and a drying device arranged in the material storage barrel and provided with a drying groove, and the drying groove is formed in the top of a sand crushing transverse plate and penetrates through the sand crushing transverse plate. The invention relates to the technical field of rail transit. According to the rail transit sanding system, the purpose of crushing caked sprayed sand is achieved, the sanding stability is improved, the water content of the sprayed sand can be controlled, it is guaranteed that the water content of the sprayed sand is kept in a proper range, and the size of a sanding opening can be adjusted according to the sanding speed.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a rail transit sand spreading system. Background technique [0002] Railway transportation uses traction and brake adhesion friction generated by wheel-rail interaction to realize the operation of trains. With the construction of high-speed railways, the traction load of electric locomotives is increasing day by day. Improving the adhesion performance of locomotives has become a crucial issue. Sand spreading is the equipment of railway vehicles. The purpose is to use sand to increase the friction between the wheel and the rail, shorten the braking distance and increase the friction of climbing. [0003] However, the existing sanding device cannot crush the agglomerated sand, the stability of the sand is poor, the water content of the sand cannot be controlled, and the water content of the sand cannot be guaranteed to be maintained in an appropriate range. The speed of the s...
