Abstract

The invention discloses a rail transit sand scattering device which comprises a storage bin, a feeding port is formed in one side of the storage bin, a discharging port is formed in the bottom of the feeding port, a material changing device is arranged in the storage bin, the material changing device is provided with a lifting plate, and the lifting plate penetrates through the storage bin and extends out of the storage bin; and a buffering device which has a buffering groove, the buffering groove is formed in one side of the inner wall of the storage bin, and an elastic film is fixedly connected between the two sides of the inner wall of the buffering groove. According to the rail transit sand scattering device, the purpose of moving and mixing scattered sand of different height layers is achieved, water accumulation and caking of scattered sand at the bottom layer can be avoided, the buffering capacity of the device is improved, abrasion of scattered sand to the inner wall of the device is reduced, the service life of the device is prolonged, scattered sand can be crushed, and scattered sand caking is prevented from being attached to the inner wall of the device.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a sand spreading device for rail transit. 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 realize the moving and mixing of sanding at different height layers, and cannot avoid agglomeration of sand and accumulated water at the bottom layer. The buffering effect is poor, and the wear of sanding on the inner wall of th...
