Referring to fig. 2, a schematic structural view of the stone discharging and sanding device according to the present invention is representatively illustrated.

Referring to fig. 3 to 7, fig. 3 is a schematic view of another angle of the stone discharging and sanding device 100; a schematic structural view of the first bracket 210 is representatively illustrated in fig. 4; a schematic structural view of the second bracket 220 is representatively illustrated in fig. 5; a schematic view of the structure of the sanding pipe 241 is representatively shown in fig. 6; an enlarged partial view of the stone dislodging sanding device 100 is representatively illustrated in fig. 7, wherein the displacement sensor 260 is specifically illustrated. The structure, connection and functional relationship of the main components of the stone discharging and sanding device 100 according to the present invention will be described in detail with reference to the above drawings.
As shown in fig. 2 and 3, in the present embodiment, the first bracket 210 may be configured to be connected to a rail vehicle, for example, detachably connected to a bogie 300 of the rail vehicle by a connector such as a bolt. The first bracket 210 has a first connection surface S1, and the first connection surface S1 is provided with a first texture P1. The second bracket 220 has a second connection surface S2, and the second connection surface S2 is provided with a second texture P2. The stone discharging mechanism 230 and the sanding mechanism are respectively disposed on the second bracket 220. On this basis, the first bracket 210 and the second bracket 220 can be detachably connected through the connecting member, and when the first bracket 210 is connected with the second bracket 220, the first connecting surface S1 is butted with the second connecting surface S2, and the first texture P1 is matched with the second texture P2, so as to limit the relative displacement of the first bracket 210 and the second bracket 220. Through the design, compared with the plane butt joint connection mode in the existing scheme, the stone removing and sanding device 100 provided by the invention can effectively prevent the connecting piece between the first support 210 and the second support 220 from loosening or breaking in the running process of the rail locomotive, effectively prolong the service life of the connecting piece and further improve the safety and reliability of the rail locomotive.
Alternatively, as shown in fig. 2 to 5, in the present embodiment, the texture of the first texture P1 may be zigzag, and the texture of the second texture P2 may be zigzag. In other embodiments, the first texture P1 and the second texture P2 may also have other matching textures, such as corrugations, etc., and are not limited to this embodiment. Through the design, along with the abrasion degree of the wheel rim of the rail locomotive, the rail locomotive wheel rim adjusting device can more conveniently achieve adjustment within the tolerance range of the installation dimension of the rail locomotive wheel rim.
Further, as shown in fig. 4 and 5, based on the design that the grain shapes of the first grain structure P1 and the second grain structure P2 are respectively zigzag, in this embodiment, the corresponding tooth shape of the zigzag grain shape of the first grain structure P1 may be a triangle, and the corresponding tooth shape of the zigzag grain shape of the second grain structure P2 may be a triangle. In other embodiments, the zigzag patterns of the first and second textures P1 and P2 may have other tooth shapes, such as trapezoidal tooth shapes, rectangular tooth shapes, and the like, which is not limited to the present embodiment.
Alternatively, as shown in fig. 2 to 4, in the present embodiment, the first bracket 210 may include a first connection plate 211, and one side surface of the first connection plate 211 defines the first connection surface S1. Also, the second bracket 220 may include a second connection plate 221, and one side surface of the second connection plate 221 defines the second connection surface S2 described above. On this basis, the connecting member for connecting the first bracket 210 and the second bracket 220 may include a bolt 250, and the bolt 250 is inserted into the first connecting plate 211 and the second connecting plate 221, so that the first bracket 210 and the second bracket 220 can be detachably connected. Accordingly, compared with the complex connection mode adopting the connecting bolt, the positioning pin and the guide groove in the prior art, the connection design of the first bracket 210 and the second bracket 220 of the invention can ensure that the two do not generate relative displacement, and simultaneously can reduce the use of connection structures such as the positioning pin and the like, and simplify the connection structure and the disassembly and assembly steps.

For example, the bolt 250 may be loosened or removed, the relative position of the first bracket 210 and the second bracket 220 in the first direction X may be readjusted, and the mounting hole 2211 still corresponds to a portion of the long hole 2111, and the bolt 250 may be reinstalled in the long hole 2111 and the mounting hole 2211, so as to adjust the connection position of the first bracket 210 and the second bracket 220 in the first direction X. In other words, the adjustable design of the first bracket 210 and the second bracket 220 requires a connector such as the bolt 250 to be detached and the relative positions of the first bracket 210 and the second bracket 220 to be readjusted, rather than dynamically adjusting the relative positions of the first bracket 210 and the second bracket 220 in a state where the bolt 250 connects the two brackets, and thus, it is still ensured that the first bracket 210 and the second bracket 220 are not relatively displaced when connected by the connector. In other embodiments, the long hole 2111 may be formed in the second connection plate 221, and the mounting hole 2211 may be formed in the first connection plate 211, which is not limited to this embodiment.
