The invention discloses a sanding device for a railway vehicle. The sanding device comprises a sand storage mechanism, an air pressure mechanism and a sand blasting mechanism, and the sand blasting mechanism comprises a control assembly and a spray pipe assembly; the control assembly comprises an air control unit used for controlling the air outlet condition of the air pressure mechanism; the spray pipe assembly comprises a sand blasting pipe, one end of the sand blasting pipe is connected with the sand storage mechanism, and the other end is provided with a sand blasting port; and the spray pipe assembly further comprises an air channel communicated with the sand blasting pipe, the air channel is connected with the air pressure mechanism through an air control unit, and the air channel is provided with an air nozzle. Through design of the air pressure mechanism and connection of the air pressure mechanism and the sand blasting mechanism, the problems that sand grains are low in flow speed and easy to accumulate in the sand pipe are solved. Meanwhile, the sand grains have a certain speed when being sprayed out of the sand blasting opening, so that the influence of crosswind interference can be eliminated.
本申请公开了一种用于轨道车辆的撒砂装置,包括储砂机构、气压机构和喷砂机构,所述喷砂机构包括控制组件和喷管组件;所述控制组件包括气控单元,用于控制气压机构的出气条件;所述喷管组件包括喷砂管,喷砂管一端与储砂机构连接,另一端设有喷砂口;所述喷管组件还包括与喷砂管连通的气道,气道通过气控单元与气压机构连接,气道设有喷气嘴。通过气压机构、以及气压机构与喷砂机构的连接设计,解决了砂粒在砂管中流速低、易堆积的问题。同时,由于砂粒从喷砂口喷出时具有一定的速度,能够消除横风干扰的影响。
