The invention relates to the technical field of rail transit equipment, and particularly discloses a railway vehicle sanding device with double pneumatic sanding units; the device comprises a box body, a first sanding unit, a second sanding unit and a sand outlet pipeline part; a first chamber and a second chamber are arranged in the box body; the first sanding unit and the second sanding unit are both arranged at the lower end of the box body and connected with the first chamber and the second chamber respectively, and the lower end of the first sanding unit and the lower end of the second sanding unit are both connected with the sand outlet pipeline component. Two independent sand spraying units are arranged and are respectively used for sanding during high-speed braking or low-speed starting, so that the requirement on air source pressure is reduced, the regulation range of the air flow regulators is reduced, the sanding rate control capability is improved, the energy is saved, and the working efficiency is improved.
本发明涉及轨道交通装备技术领域,具体公开了一种带有双气动撒砂单元的轨道车辆撒砂装置,包括箱体、第一撒砂单元、第二撒砂单元和出砂管路部件,所述箱体的内部设有第一腔室和第二腔室,所述第一撒砂单元和第二撒砂单元均设在所述箱体的下端且分别与所述第一腔室和第二腔室连接,所述第一撒沙单元和第二撒沙单元的下端均与所述出砂管路部件连接,本发明有两个独立的撒砂单元,分别用于高速制动或低速启动时撒砂,降低了对风源压力的要求,缩小了气流调节器的调节范围使得撒砂速率的控制能力得以提高,不仅节约了能源还提高了工作效率。
