[0020] 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.

[0021] Please see Figures 1 to 4This utility model provides a technical solution: a railway track maintenance device, including a movable base 1, a support frame 2 installed on one side of the movable base 1, and two support plates 3 rotatably connected to corresponding ends of the bottom of the support frame 2. A first positioning rod 4 and a second positioning rod 5 are connected to the bottom of each of the two support plates 3. A first brush 6 and a second brush 7 are respectively connected to the bottom of the first positioning rod 4 and the second positioning rod 5. The first brush 6 and the second brush 7 are both L-shaped, allowing the first brush 6 and the second brush 7 at the bottom of adjacent support plates 3 to surround the track and contact three sides of the track, which is beneficial for expanding the application range of lubricating oil. A control groove 8 is provided inside the support frame 2, and multiple worm gears 9 are rotatably connected inside the control groove 8. A worm gear 10 is rotatably connected to one side of multiple worm wheels 9. The worm gear 10 meshes with the multiple worm wheels 9, and the multiple worm wheels 9 are connected to multiple support plates 3. Under the action of the worm gear 10 and the multiple worm wheels 9, the multiple support plates 3 are driven to rotate simultaneously, so that the used first brush 6 and the unused second brush 7 of each set at the bottom of the support plate 3 are swapped, or the used second brush 7 and the unused first brush 6 are swapped, which automatically changes the brushes and improves efficiency. A self-locking motor 11 is fixedly installed on one side of the support frame 2. The output end of the self-locking motor 11 is connected to the worm gear 10 to provide power for the rotation of the worm gear 10 and the support plate 3. The first positioning rod 4 and the second positioning rod 5 respectively include a first rod body 41 and a third rod body 51. The first rod body 41 The second rod 42 and the fourth fixed rod 52 are respectively inserted into the interior of the first rod 41 and the third rod 51. A first locking bolt 43 and a second locking bolt 53 are threaded onto one side of the first rod 41 and the third rod 51, respectively. One end of the first locking bolt 43 and the second locking bolt 53 extends into the first rod 41 and the third rod 51, respectively. As the first locking bolt 43 and the second locking bolt 53 rotate, one end of them shifts, pressing or loosening the second rod 42 and the fourth fixed rod 52. This plug-in structure of the second rod 42 and the fourth fixed rod 52 facilitates the fixing or separation of the second rod 42 or the fourth fixed rod 52, thereby allowing for the installation and removal of the first brush 6 or the second brush 7. An oil storage tank 12 is installed on the top of the movable base 1. A lubricating oil pump 13 is installed on one side of the oil tank 12. The input end of the lubricating oil pump 13 is connected to the oil storage tank 12, and the output end of the lubricating oil pump 13 is connected to a guide pipe 14. One end of the guide pipe 14 is connected to a guide frame 15. The bottom two sides of the guide frame 15 are connected to a first nozzle 16 and a second nozzle 17. Under the action of the lubricating oil pump 13, lubricating oil is sprayed onto the surface of the track, which is beneficial for lubrication and maintenance. The first nozzle 16 and the second nozzle 17 are both tilted inward, so that the lubricating oil can be sprayed towards the top and the outside of the track at the same time, making the lubrication more thorough. The top of the oil storage tank 12 and the side of the oil storage tank 12 adjacent to the lubricating oil pump 13 are respectively connected to an inlet pipe 18 and a drain pipe 19. Valves are provided on one side of the inlet pipe 18 and the drain pipe 19.To facilitate the injection and discharge of lubricating oil, a handle 20 is installed on the top of the movable base 1, located on one side of the oil reservoir 12, for easy hand-holding and pushing of the device. A controller 21 is installed on the top of the movable base 1, between the drain pipe 19 and the handle 20.

[0022] In summary, when using this railway track maintenance device, the first brush 6 and the second brush 7, whose bottom positions are opposite each other on two adjacent support plates 3, are aligned with the track. After they are attached to the sides and top of the track, the lubricating oil pump 13 draws the lubricating oil from the oil tank 12 into the guide frame 15 through the guide pipe 14. Then, the first nozzle 16 and the second nozzle 17 spray the oil onto the surface of the track, pushing the movable base 1 to move and causing the first brush 6 and the second brush 7 to spread the lubricating oil evenly on the track surface. When it is necessary to replace the first brush 6 and the second brush 7, the self-locking motor 11 drives the worm gear 10 inside the support frame 2 to rotate. Since the worm gear 10 meshes with multiple worm wheels 9, and the multiple worm wheels 9 are respectively connected to multiple support plates 3, the multiple worm wheels 9 rotate accordingly, so that the first brush 6 at the bottom of the support plate 3 after use is replaced with the unused brush 7. The second brush 7 can be swapped, or the used second brush 7 can be swapped with the unused first brush 6, so that the new first brush 6 and the second brush 7 can take over the application of lubricating oil on the track. Similarly, at the bottom of the support plate 3, the first rod 41 and the third rod 51 are respectively inserted into the second rod 42 and the fourth fixed rod 52. Under the action of the second rod 42 and the fourth fixed rod 52 being connected to the first brush 6 and the second brush 7 respectively, the first locking bolt 43 and the second locking bolt 53 threaded on one side of the first rod 41 and the third rod 51 are rotated respectively, so that one end of them is displaced, and the clamping on the second rod 42 and the fourth fixed rod 52 is loosened respectively. Then the second rod 42 and the fourth fixed rod 52 can be pulled out from the first rod 41 and the third rod 51 respectively, and the first brush 6 and the second brush 7 can be disassembled.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
