[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 5 This utility model provides a technical solution: a track cleaning device, comprising: a top support 1; a track body 2 placed below the top support 1; a bottom fixed support box 4 fixedly installed at the bottom of the top support 1 by bolts; two bottom sliding support plates 3 are provided, symmetrically slidingly arranged at the bottom of the top support 1, and two limiting guide plates 21 are symmetrically slidably arranged inside the two bottom sliding support plates 3; a side mounting bracket 23 is fixedly installed on one side of the limiting guide plate 21 by bolts, and a second anti-slip wheel 24 is rotatably arranged on the inner side of the side mounting bracket 23; two rotating support rods 28 are provided, rotatably arranged inside the bottom fixed support box 4, and two first anti-slip wheels 5 are symmetrically fixed to the outer side of the rotating support rods 28, and sprockets 6 are fixedly fixed to the outer side of the two rotating support rods 28, and the two sprockets 6 are connected by chain drive; a cleaning brush 17 is installed inside the bottom fixed support box 4 by bolts; and a cleaning scraper 20 is installed on one side of the bottom fixed support box 4.

[0027] It should be noted that in this embodiment, the device is powered by an external battery and power supply. A bidirectional lead screw 8 is rotatably mounted inside the top support 1. Two movable sliders 9 are symmetrically mounted on the outer side of the bidirectional lead screw 8. The movable sliders 9 are slidably connected to the top support 1, and their bottoms are fixedly connected to the bottom sliding support plate 3. When it is necessary to adapt to tracks of different widths, the second motor 11 is started, driving the bidirectional lead screw 8 to rotate. Due to the characteristics of the bidirectional lead screw 8, the two movable sliders 9 will move symmetrically in a straight line along the bidirectional lead screw 8. The first limiting rod 10 limits and guides the movement of the movable sliders 9, ensuring the smoothness and accuracy of their movement. This will cause the bottom sliding support plate 3 to move synchronously, thereby adjusting the distance between the two bottom sliding support plates 3 to adapt to tracks of different widths. The second anti-slip wheel 24 will be subjected to forces in different directions. The side mounting bracket 23 will drive the limiting guide plate 21 to slide within the bottom sliding support plate 3. The return spring 25 will be compressed or stretched. The elastic force of the return spring 25 will cause the side mounting bracket 23 to return to its position. The limiting plate 22 will prevent the limiting guide plate 21 from sliding out of the bottom sliding support plate 3, so that the second anti-slip wheel 24 can better adapt to the surface conditions of the track, and has a certain buffering and self-adaptive ability to ensure the anti-slip effect. The first motor 7 is started, and the first motor 7 drives the rotating support rod 28 fixed to it to rotate. The sprocket 6 on the rotating support rod 28 passes through... The chain drives the sprocket 6 on another rotating support rod 28 to rotate, thereby causing the two rotating support rods 28 to rotate synchronously, driving the first anti-slip wheel 5 to rotate, realizing the movement of the device on the track. The cleaning brush 17 is installed inside the bottom fixed support box 4 by bolts. Side T-shaped positioning blocks 18 are fixed to both sides of the cleaning brush 17. Two T-shaped positioning grooves 19 are symmetrically opened on the inner side of the bottom fixed support box 4 to cooperate with the side T-shaped positioning blocks 18. When installing the cleaning brush 17, the cooperation between the side T-shaped positioning blocks 18 and the T-shaped positioning grooves 19 can achieve quick positioning, ensure the accuracy of the installation position, prevent installation deviation from affecting the cleaning effect, and prevent the cleaning brush 17 from shaking or... The cleaning scraper 20 is installed on one side of the bottom fixed support box 4. A connecting side seat 13 is fixedly connected to one side of the cleaning scraper 20. A side fixed seat 12 that mates with the connecting side seat 13 is fixedly connected to one side of the bottom fixed support box 4. Four fixing screws 15 are symmetrically fixed to one side of the side fixed seat 12. Four mounting through holes 14 that mate with the fixing screws 15 are symmetrically opened inside the connecting side seat 13. Limit nuts 16 are installed on the outside of the fixing screws 15. Washers are sleeved on the outside of the fixing screws 15. This structure makes the cleaning scraper 20 firmly installed and easy to replace or maintain. During the movement of the device along the track, the cleaning scraper 20 first scrapes away larger debris on the track surface, and then the cleaning brush 17 further cleans the track surface.

[0028] The specific architecture and operating logic of the motor and battery achieving coordinated control through an external controller in this application are consistent with the existing technology in this field.

[0029] In one embodiment, such as Figures 1 to 5 As shown, a connecting side seat 13 is fixedly connected to one side of the cleaning scraper 20, and a side fixing seat 12 that mates with the connecting side seat 13 is fixedly connected to one side of the bottom fixing support box 4.

[0034] It should be noted that in this embodiment, when the cleaning brush 17 is installed inside the bottom fixed support box 4, it can be quickly positioned by the cooperation of the side T-shaped positioning block 18 and the T-shaped positioning groove 19, which facilitates installation and ensures the accuracy of the installation position of the cleaning brush 17, preventing installation deviation from affecting the cleaning effect. In subsequent use, this positioning structure can also prevent the cleaning brush 17 from shaking or shifting.

[0035] In one embodiment, such as Figures 1 to 5 As shown, a limiting plate 22 is fixedly connected to the side of the limiting guide plate 21 away from the side mounting bracket 23. A return spring 25 is sleeved on the outer side of the limiting guide plate 21. One end of the return spring 25 is fixedly connected to the side mounting bracket 23, and the other end of the return spring 25 is fixedly connected to the bottom sliding support plate 3.

[0036] It should be noted that in this embodiment, the second anti-slip wheel 24 is able to better adapt to the surface conditions of the track, and has a certain buffering and self-adaptive ability to ensure the anti-slip effect.

[0037] In one embodiment, such as Figures 1 to 5 As shown, accordion cloth 27 is provided between both sides of the movable slider 9 and the top support 1.
