The invention relates to the technical field of railway vehicle sanding systems, in particular to a railway vehicle sand box cover and a sanding system.The railway vehicle sand box cover comprises a base, an end cover, a sealing piece and a pressing assembly, and an opening right facing a sand inlet is formed in the base; the end cover is arranged at the opening; the sealing piece is embedded in the side, facing the opening, of the end cover, and the sealing piece and the opening are correspondingly arranged; the pressing assembly is rotationally connected with the base and can press the end cover so that the sealing piece can abut against the edge of the opening. The end cover is pressed through the pressing assembly, so that the sealing piece abuts against the edge of the opening of the base, the sand inlet can be effectively sealed, the requirement for air pressure during sanding can be met, the waterproof effect can be achieved, the structure is simple, installation is convenient, and the problem that an existing railway vehicle sand box cover is poor in sealing performance is effectively solved.
本发明涉及轨道车辆撒砂系统技术领域,尤其涉及一种轨道车辆砂箱盖及撒砂系统,轨道车辆砂箱盖包括底座、端盖、密封件和压紧组件,底座上开设有正对进砂口设置的开口;端盖设置于开口处;密封件嵌设于端盖面向开口的一侧,且密封件与开口对应设置;压紧组件与底座转动连接,压紧组件能够压紧端盖,以使密封件与开口边缘抵紧设置。本发明通过压紧组件对端盖进行压紧,以使密封件抵紧于底座的开口边缘,能够对进砂口进行有效地密封,以满足撒砂时对气压的要求,且能够起到防水的作用,结构简单,安装方便,有效地解决了现有的轨道车辆砂箱盖密封性能差的问题。
