On the other hand, the cleaning component can blow out a clean airflow, and the airflow cleans the dust or foreign matter remaining on the bridge frame 1 and the guide rail 2 again. At the same time, the cleaning component blows and cleans the dust on the roller 11;

[0035] The cleaning component is fixedly connected to one end of the side box 7 away from the cleaning component. The cleaning component cooperates with the bridge frame 1 and the guide rail 2 respectively, and the cleaning component cooperates with the roller 11. The detector installed in the side box 7 drives the cleaning component to run. The cleaning component sprays clean water on the bridge frame 1 and the guide rail 2. The water flow performs secondary cleaning on the foreign matter or dust remaining on the bridge frame 1 and the guide rail 2, thereby ensuring the cleanliness of the bridge frame 1 and the guide rail 2. The cleaning component cleans the surface of the roller 11, thereby ensuring the cleanliness of the surface of the roller 11. When the bridge frame 1 and the guide rail 2 are cleaned, the cleaning component stops running and the cleaning component continues running. The wind blown out by the cleaning component cleans the water droplets left on the bridge frame 1 and the guide rail 2 to avoid water droplets remaining on the bridge frame 1 and the guide rail 2, thereby avoiding the phenomenon of water droplets causing corrosion to the bridge frame 1 and the guide rail 2.

[0036] In some specific embodiments, a fillet 3 is provided on the top of the guide rail 2, and the cross-section of the fillet 3 is semicircular. A matching groove 25 is provided axially on the roller 11. The fillet 3 is matched and connected with the matching groove 25, and the inner wall of the matching groove 25 is abutted and connected with the guide rail 2. When the cleaning component and the washing component are running, the fillet 3 on the top of the guide rail 2 can facilitate the separation of dust from the guide rail 2, further improving the cleaning effect of the cleaning component and the washing component on the guide rail 2. The guide rail 2 and the inner wall of the matching groove 25 abut against each other, which can ensure that the guide rail 2 limits the roller 11 and avoids the roller 11 from deviating when moving along the guide rail 2, thereby realizing the guiding function of the guide rail 2 on the roller 11.

The foreign matter accumulates on the cleaning plate 4 and the cleaning scraper 19 and eventually detaches from the bridge frame 1. The blower 5 blows clean air from the vertical nozzle 20. The vertical nozzle 20 is aimed at the top of the bridge frame 1 and the guide rail 2. The vertical nozzle 20 blows the airflow to the bridge frame 1 and the guide rail 2, thereby performing preliminary cleaning of the foreign matter or dust left on the bridge frame 1 and the guide rail 2. The horizontal nozzle 21 blows the airflow to the surface of the roller 11, performs preliminary cleaning of the dust on the surface of the roller 11, and prevents the dust on the roller 11 from adhering to the bridge frame 1 and the guide rail 2 when the roller 11 rotates and moves along the bridge frame 1 and the guide rail 2.

[0038] In some specific embodiments, a water tank 8 is fixedly connected to the top of the trolley 6, and a guide pipe 12 is provided between the water tank 8 and the cleaning component. Both ends of the guide pipe 12 are fixedly connected to the water tank 8 and the cleaning component respectively. When the cleaning component is running, the water tank 8 can pass the stored water into the cleaning component through the guide pipe 12, thereby ensuring that the cleaning component can obtain sufficient water to clean the bridge frame 1 and the guide rail 2.

[0039] In some specific embodiments, the cleaning assembly includes: a sprinkler 13, a vertical sprinkler head 22 and a horizontal sprinkler head 23. The sprinkler 13 is fixedly connected to the side end of the side box 7. The vertical sprinkler head 22 is provided with a plurality of groups and is evenly distributed at the bottom end of the sprinkler 13. The vertical sprinkler head 22 is fixedly connected to the bottom end of the sprinkler 13. The vertical sprinkler head 22 is respectively matched with the bridge 1 and the guide rail 2. The horizontal sprinkler head 23 is fixedly connected to one end of the sprinkler 13 close to the roller 11. The horizontal sprinkler head 23 is matched with the roller 11. When When the cleaning component is running, the sprinkler 13 draws out the water stored in the water tank 8 through the guide pipe 12, and the sprinkler 13 sprays the water onto the bridge 1 and the guide rail 2 through the vertical sprinkler head 22. The sprayed water cleans the surface of the bridge 1 and the guide rail 2, and the water flow washes the adhered dust, and the dust flows out from the bridge 1 with the water flow. The water sprayed by the horizontal sprinkler head 23 cleans the surface of the roller 11, and the water flow carries the dust along the matching groove 25 to the bridge 1, thereby achieving sufficient cleaning of the dust.

[0040] In some specific embodiments, an injector 10 is provided on the top of the side box 7, and a plurality of support rods 9 are provided between the side box 7 and the injector 10. The plurality of support rods 9 are respectively located around the injector 10, and the upper and lower ends of the support rods 9 are respectively fixedly connected to the side box 7 and the injector 10, and the bottom of the injector 10 is fixedly connected to an injector head 24, and the injector head 24 cooperates with the roller 11. When the surface of the bridge frame 1 and the guide rail 2 are cleaned, the cleaning component and the washing component stop running, and the injector 10 sprays the stored lubricating oil onto the roller 11 through the injector head 24, and the lubricating oil flows along the matching groove 25 to the guide rail 2. When the roller 11 rotates and moves, the lubricating oil can be distributed on the bridge frame 1, the guide rail 2 and the roller 11, and the lubricating oil protects the surface of the bridge frame 1, the guide rail 2 and the support rod 9 to avoid rust. At the same time, the lubricating oil can reduce the friction of the roller 11 rotating along the bridge frame 1 and the guide rail 2, thereby reducing the load of the trolley 6.

[0041] In some specific implementation schemes, a rotating shaft 15 is fixedly connected to the side end of the roller 11, a rotating hole 14 is axially opened in the side box 7, the rotating shaft 15 is rotatably connected to the inner wall of the rotating hole 14, a sealing gasket 16 is fixedly connected to the outer wall of the rotating shaft 15, a circular plate 17 is fixedly connected to the side end of the rotating shaft 15, the sealing gasket 16 is rotatably connected to the side box 7, a semi-cylindrical limiting plate 26 is axially fixedly connected to the outer wall of the circular plate 17, a plurality of limiting grooves 18 are equidistantly opened on the top of the bridge 1 along the length direction, and the limiting plates 26 cooperate with the limiting grooves 18. When the roller 11 rotates, the roller 11 rotates along the inner wall of the rotating hole 14 with the rotating shaft 15, and the rotating shaft 15 rotates with the circular plate 17. The limiting plates 26 fixed on the surface of the circular plate 17 are embedded in the limiting grooves 18 in sequence. When the roller 11 stops rotating, the lubricating oil causes the roller 11 to be offset and misaligned on the bridge 1 and the guide rail 2. When the roller 11 stops rotating, the rotating shaft 15 stops rotating with the circular plate 17. At this time, the limit plate 26 is embedded in the limit groove 18. The limit plate 26 and the inner wall of the limit groove 18 abut against each other to provide a limiting effect for the circular plate 17. The circular plate 17 transmits the limiting effect to the roller 11 through the rotating shaft 15, thereby avoiding the roller 11 from being offset and misaligned on the bridge 1 and ensuring the stability of the roller 11. The sealing gasket 16 rotates synchronously with the rotating shaft 15, and the rotating shaft 15 can seal the gap between the rotating hole 14 and the rotating shaft 15 to avoid dust from entering the gap and causing greater friction when the rotating shaft 15 rotates.

[0042] Several embodiments of the present invention are described in detail above, but the embodiments of the present invention are not limited thereto and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
