The invention provides a stone removing and sanding device and a rail locomotive. The stone removing and sanding device comprises a first support, a second support, a stone removing mechanism and a sanding mechanism. The first support is used for being connected to a rail locomotive and is provided with a first connecting surface, and the first connecting surface is provided with a first grain structure. The second support is provided with a second connecting surface, and the second connecting surface is provided with a second grain structure; the stone discharging mechanism and the sanding mechanism are respectively arranged on the second support; the first support and the second support are detachably connected through a connecting piece, the first connecting surface is in butt joint with the second connecting surface, and the first grain structure is matched with the second grain structure to limit the relative displacement of the first support and the second support. By means of the design, the first grain structure and the second grain structure are designed in a matched mode, the loosening or breaking of connection between the first support and the second support can be effectively prevented, the service life of the connecting piece is effectively prolonged, and then the safety and reliability of the rail locomotive are improved.

    本发明提出一种排石撒砂装置及轨道机车;排石撒砂装置包含第一支架、第二支架以及排石机构和撒砂机构;第一支架用以连接于轨道机车,并具有第一连接表面,第一连接表面设置有第一纹路结构;第二支架具有第二连接表面,第二连接表面设置有第二纹路结构;排石机构和撒砂机构分别设置于第二支架;第一支架与第二支架通过连接件可拆装地连接,第一连接表面与第二连接表面相对接,第一纹路结构与第二纹路结构相配合,以限制第一支架与第二支架的相对位移。通过上述设计,本发明采用第一纹路结构与第二纹路结构的配合设计,可以有效地预防第一支架与第二支架之间的连接发生松动或断裂、有效地延长连接件的使用寿命,进而提升轨道机车的安全性和可靠性。
