[0002] Railcars (including trailers, the same below) are the main means of transportation for railway equipment maintenance, overhaul, infrastructure and other construction departments to perform tasks. Railcars are divided into heavy and light types. Those that can be evacuated from the line at any time by passengers are called light railcars; those that cannot be evacuated from the line at any time by passengers are called heavy railcars.

[0003] Alloy wear plate is one of the important friction parts required by rail vehicles when running. During the operation of the vehicle, it plays an important role in absorbing energy and reducing vibration and improving the dynamic performance of the train. Its performance is also an important factor directly related to transportation safety.

[0004] Most of the existing alloy wear plates for rail vehicles are cast in one piece during the production process. When the alloy wear plates for rail vehicles are used for a long time, due to the different running speeds of the rail vehicles, the alloy wear plates will be greatly worn locally or in a certain section. When replacing them, maintenance personnel are required to replace the alloy wear plates for rail vehicles as a whole, which causes waste of alloy wear plates for rail vehicles and increases maintenance costs. Therefore, we need to upgrade and transform them based on the existing technology. Utility Model Content

[0026] Preferably, both alloy plate 1 2 and alloy plate 2 3 are provided with running grooves 4, and multiple groups of running grooves 4 are provided. By providing the running grooves 4, it is convenient for the vehicle to directional travel on alloy plate 1 2 and alloy plate 2 3. A countersunk groove 9 is provided in the splicing buckle 5, and the countersunk groove 9 is located above the first screw hole 10. The upper end of the annular bolt 12 is connected to the bolt head 11, and the bolt head 11 is installed in the countersunk groove 9. By providing the countersunk groove 9, the bolt head 11 can be fixed and limited, thereby ensuring the safety of the bolt head 11 and avoiding the situation where the bolt head 11 is exposed outside the device and affects the aesthetics of the device. Multiple groups of bolt heads 11 are provided, and cross grooves 13 are fixedly provided in the multiple groups of bolt heads 11. By providing the cross groove 13, it is convenient for maintenance personnel to disassemble the bolt head 11 and the annular bolt 12 at a later time, thereby avoiding the trouble of inconvenient disassembly and assembly of the device.

[0027] Preferably, a clamping plate 19 is fixedly provided at one end of the L base 17, a clamping slot 20 is provided in the L base 2 18, and multiple groups of clamping plates 19 and clamping slots 20 are provided.

[0028] The use principle and use process of the utility model: when in use, the user takes the alloy plate 1 2 and the alloy plate 2 3 to the designated installation position, adjusts the plug-in plate 6 and the splicing buckle 5 of the alloy plate 1 2 to the plug-in slot 7 and the splicing slot 8 of the alloy plate 2 3, and after the adjustment is completed, the splicing buckle 5 and the plug-in plate 6 are simultaneously plugged into the splicing slot 8 and the plug-in slot 7. After the plugging is completed, the user plugs the annular bolt 12 with the bolt head 11 into the first screw hole 10. After the plugging, the annular bolt 12 is screwed into the first screw hole 10 by rotating the cross slot 13 with the help of a tool. The user then rotates the mounting plate 16 in the placement groove 14 to the outside through the friction shaft 15, and sequentially places the L base 17 and the L base 2 18 under the mounting plate 16, and snaps the clamping plate 19 of the L base 17 with the clamping groove 20 of the L base 2 18. After the snapping is completed, the positions of the second screw holes 21 of the L base 17 and the L base 2 18 are adjusted to be consistent with the positions of the second screw holes 21 of the mounting plate 16, and the washer 23 is movably mounted on the hexagonal bolt 22. The user uses a tool to tighten the hexagonal bolt 2 2 is screwed and installed in the second screw hole 21, and is screwed until the washer 23 and the hexagonal bolt 22 are in close contact with the surface of the L base 17 and the L base 2 18. The device can be assembled and installed, which improves the installation efficiency and ensures the safety and stability of the device during use. When the device is severely worn locally during use and a local plate needs to be replaced, the user uses a tool to remove the hexagonal bolt 22 above the plate to be replaced from the second screw hole 21. After the hexagonal bolt 22 is removed, the plate is separated from the base, and then the plate is removed by using a tool. The tool is used to rotate the cross slot 13, and the bolt head 11 and the ring bolt 12 are taken out from the first screw hole 10 and the countersunk groove 9 in turn. After taking them out, the user pulls the plate to be replaced outward until the plug-in plate 6 and the splicing buckle 5 of the plate are separated from the splicing groove 8 and the plug-in groove 7 of the other end plate, and then the new alloy plate is reinstalled and fixed. The alloy plate in the device can be partially disassembled and replaced according to the needs of use, which increases the practicality and convenience of the device, reduces the maintenance cost, and avoids the problem that the traditional integrated alloy plate needs to be replaced as a whole during maintenance.
