[0002] High-speed rail, due to its high mobility and speed, has gradually become the main mode of transportation for people's daily long-distance travel. Since the speed of high-speed rail is much greater than that of ordinary trains, its requirements for the track are relatively more stringent. Therefore, during the laying and use of high-speed rail tracks, they need to be ground and repaired to remove rust and other impurities from the rail surface.

[0003] For example, Chinese patent CN220013529U discloses a special grinding and cleaning machine for high-speed train tracks. This type of device is configured with a counterweight device and uses track rollers and cleaning components to restrict the entire device on the track. By pushing the entire device, the cleaning components rub against the surface of the track, thereby grinding and cleaning the top and sides of the track to remove rust and impurities from the top and sides of the track.

[0004] However, the aforementioned disclosed patents and existing track grinding devices in the market still have some shortcomings: the existing brush-based relative friction grinding method has poor grinding initiative and low grinding capacity, often failing to effectively remove rust and other impurities from high-speed rail tracks. Therefore, those skilled in the art have provided a grinding and finishing device for high-speed rail tracks to solve the problems mentioned in the background art. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This utility model provides a technical solution for a grinding and finishing device for high-speed rail tracks: A grinding and finishing device for high-speed rail tracks includes a high-speed rail track and a support base 11 disposed above the high-speed rail track. The support base 11 has a first drive shaft 12 inside, and a main grinding wheel 8 is disposed along the axial direction of the support base 11, with the main grinding wheel 8 facing the rail surface of the high-speed rail track. Inside the support base 11, offset from the first drive shaft 12, there is also a lead screw 16. Two sets of slides 17 are disposed along the axial direction of the lead screw 16, and a housing 14 is disposed below the slides 17. The bottom of the housing 14 has a side grinding wheel 9, which faces the side of the high-speed rail track. A drive assembly is also provided to drive the side grinding wheel. Grinding wheel 9 moves towards the side of the high-speed rail track, and after moving, drives the main grinding wheel 8 and the side grinding wheel 9 to operate, grinding the high-speed rail track. After the main grinding wheel 8 is pressed flat against the rail surface, the drive assembly first drives the side grinding wheel 9 to move closer to the side of the high-speed rail track (by pre-positioning the side grinding wheel 9 away from the side of the high-speed rail track to provide clearance, so that after the main grinding wheel 8 is pressed flat against the rail surface, the side grinding wheel 9 can move and extend to the side of the high-speed rail track), making close contact with the side of the high-speed rail track. Then, the drive assembly drives the main grinding wheel 8 and the side grinding wheel 9 to operate synchronously, performing an active grinding and finishing process on each surface of the high-speed rail track. Specifically: The first drive shaft 12 has two sets of prismatic shafts 13 axially, and a prismatic bushing 15 rotatably mounted to the housing 14 is provided on the prismatic shaft 13 axially. A drive sector gear 20 is provided on the prismatic bushing 15. A second drive shaft 18 is rotatably mounted on the housing 14. One end of the second drive shaft 18 is fixedly connected to the side grinding wheel 9, and the other end is fixedly connected to the driven sector gear 19. The driven sector gear 19 meshes with the drive sector gear 20. Through the cooperation of the prismatic bushing 15 and the prismatic shaft 13, the drive sector gear 20... It has the characteristics of sliding and rotating along the first drive shaft 12. Then, when the opposite grinding wheel 9 moves and is adjusted, the driving sector gear 20 slides along the first drive shaft 12. When the first drive shaft 12 drives the main grinding wheel 8 to rotate, it also drives the driving sector gear 20 to rotate. By using the meshing transmission between the driving sector gear 20 and the driven sector gear 19, the second drive shaft 18 is driven to rotate, which in turn drives the side grinding wheel 9 to rotate, so that the main grinding wheel 8 and the side grinding wheel 9 operate synchronously, and perform active grinding and finishing processes on various parts of the high-speed rail track.

[0018] It should be noted that the lead screw 16 is divided by the center line, and the two sides of the center line are provided with positive and negative threads that are compatible with the two sets of slides 17. When the grinding wheels 9 on the opposite side move and are adjusted, the lead screw 16 is rotated by controlling the lead screw 16. With the cooperation of the positive and negative threads on the lead screw 16 and the two sets of slides 17, a driving force is generated that acts on the two sets of outer shells 14 to slide relative to each other along the prism axis 13, so that the two sets of side grinding wheels 9 move closer to the sides of the high-speed rail track.

[0019] As a further embodiment of this invention, the drive assembly includes a second drive shaft 7 located axially on the lead screw 16 and a second motor 6 located on one side of the second drive shaft 7. The second motor 6 is fixed to one side of the support frame 1, and a second transmission belt 10 is provided between the second motor 6 and the second drive shaft 7. By controlling the operation of the second motor 6, the second drive shaft 7 is driven to rotate in cooperation with the second transmission belt 10, which in turn drives the lead screw 16 to rotate, generating a driving force that acts on the side grinding wheel 9 to move closer to the side of the high-speed rail track.

[0020] Furthermore, the drive assembly also includes a first drive shaft 5 located axially on the first drive shaft 12, and a first motor 3 located on one side of the first drive shaft 5. The first motor 3 is fixed to the other side of the support frame 1. A first transmission belt 4 is provided between the first motor 3 and the first drive shaft 5. By controlling the operation of the first motor 3, the first drive shaft 5 is driven to rotate under the cooperation of the first transmission belt 4, which in turn drives the first drive shaft 12 to rotate, generating a driving force that acts on the main grinding wheel 8 and the side grinding wheel 9 to rotate synchronously.

[0021] In addition to the above, a support frame 1 is provided above the support base 11, and at least one set of arm frames 2 is provided above the support frame 1. Through the cooperation of the support frame 1 and the arm frames 2, the overall structure of the device can be loaded onto equipment such as a traveling trolley. By pushing the device forward on the high-speed rail track, the rust and other impurities on the high-speed rail track can be polished and repaired.

[0022] The working principle of this utility model is as follows: When grinding and repairing high-speed rail tracks, the device is mounted on a traveling trolley or other equipment, so that the main grinding wheel 8 is pressed flat against the rail surface of the high-speed rail track, and the side grinding wheel 9 is facing the side of the high-speed rail track. Then, by controlling the second motor 6 to work, the second drive shaft 7 is driven to rotate in cooperation with the second transmission belt 10, which in turn drives the lead screw 16 to rotate. With the cooperation of the positive and negative threads on the lead screw 16 and the two sets of slides 17, a driving force is generated that acts on the two sets of housings 14 to slide relative to each other along the prism shaft 13, causing the two sets of side grinding wheels 9 to move closer to the sides of the high-speed rail track. Furthermore, while the side grinding wheel 9 moves, the engagement of the prismatic bushing 15 and the prismatic shaft 13 enables the drive sector gear 20 to slide and rotate along the first transmission shaft 12. Then, during the adjustment of the side grinding wheel 9, the drive sector gear 20 slides along the first transmission shaft 12, always meshing with the driven sector gear 19. Subsequently, by controlling the first motor 3 to operate, the first drive shaft 5 rotates under the engagement of the first transmission belt 4, which in turn rotates the first transmission shaft 12. This causes the first transmission shaft 12 to rotate the main grinding wheel 8 and simultaneously drive the drive sector gear 20. The meshing of the drive sector gear 20 and the driven sector gear 19 drives the second transmission shaft 18 to rotate, which in turn drives the side grinding wheel 9 to rotate. This allows the main grinding wheel 8 and the side grinding wheel 9 to operate synchronously, performing active grinding and finishing processes on various parts of the high-speed rail track.

[0023] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
