Description

Technical Field

[0001] The utility model relates to the field of urban transportation, in particular to an urban traffic track cleaning device. Background Art

[0002] Track cleaning refers to the process of cleaning the tracks of subways or other rail transit systems. Since various sundries, such as dust and debris, will accumulate on the subway tracks, these sundries may affect the driving safety of trains and reduce the power supply capacity of the tracks. Currently, special track cleaning vehicles are mostly used to remove the sundries on the tracks through equipment such as rotating brushes and vacuum cleaners. This method is relatively cumbersome and inefficient.

[0003] The current cleaning device is not convenient for shaking off the dust attached to the sponge column, which leads to insufficient cleaning of the steel rail. And dust may accumulate in front of the device and cannot fall from the steel rail. The existing cleaning device is not convenient for scraping off the accumulated dust on the steel rail, which leads to low cleaning efficiency of the steel rail. Summary of the Utility Model

[0004] In order to overcome the above-mentioned drawbacks, the utility model provides an urban traffic track cleaning device, which can shake off the dust attached to the sponge column, so as to clean the steel rail more fully, and can scrape off the accumulated dust in front of the sponge column, so as to improve the cleaning efficiency of the sponge column.

[0005] The technical implementation scheme of the utility model is: an urban traffic track cleaning device, which includes a fixed frame, an outer frame, a support plate, a limiting plate, a motor, a rhombic shaft and a sponge column. The bottom of the fixed frame is fixedly connected with the outer frame. One side of the inner wall of the outer frame is fixedly connected with the support plate. The other side of the inner wall of the outer frame is fixedly connected with the limiting plate. A round hole is opened on the limiting plate. The support plate is fixedly connected with the motor. The output shaft of the motor is fixedly connected with the rhombic shaft. The rhombic shaft passes through the round hole of the limiting plate. The sponge column is slidably connected to the rhombic shaft. The sponge column contacts the top of the steel rail.

[0006] Furthermore, it also includes a pressing block, a pressed block and a compression spring. The pressing block is fixedly connected to one end of the sponge column close to the motor. The support plate is fixedly connected with the pressed block. A compression spring is connected between the end of the sponge column far from the motor and the limiting plate.

[0007] Furthermore, it also includes a fixed shaft, a large gear, a rotating shaft, a small gear, a bidirectional lead screw and a scraping block. The fixed shaft is fixedly connected to the end of the rhombic shaft far from the motor. The large gear is fixedly connected to the fixed shaft. The rotating shaft is rotatably connected to the limiting plate. One side of the rotating shaft is fixedly connected with the small gear. The large gear meshes with the small gear. The end of the rotating shaft far from the small gear is fixedly connected with the bidirectional lead screw. The scraping block is threadedly connected to the bidirectional lead screw. The scraping block contacts the top of the steel rail.

[0008] Furthermore, it also includes a scraper which is fixedly connected to the top of the inner wall of the outer frame and contacts the sponge column.

[0009] The utility model has the following advantages: 1. In the utility model, the motor drives the rhombic shaft and the sponge column to rotate together. The rotation of the sponge column will clean the dust on the top of the rail, so that the rail can be in full contact with the vehicle, thus enabling the rail to transmit electricity more effectively. While the sponge column rotates, it will drive the extrusion block to rotate, so that the extrusion block will drive the sponge column to swing left and right reciprocally through the compression block and the compression spring, thereby shaking off the dust attached to the sponge column and cleaning the rail more thoroughly.

[0010] 2. While the sponge column rotates, it will drive the fixed shaft and the large gear to rotate together. The rotation of the large gear will drive the rotating shaft and the bidirectional lead screw to rotate through the small gear. The rotation of the bidirectional lead screw will drive the scraping block to move left and right reciprocally along the top of the rail, thereby scraping off the dust that may accumulate in front of the sponge column onto the rail, thus improving the cleaning efficiency of the sponge column for the rail. While the sponge column rotates, it passes by the scraper, and the scraper will indirectly scrape the sponge column, thereby scraping off the wet dust that cannot be shaken off on the sponge column, so that the sponge column can clean the rail more thoroughly.

The bottom of the fixed frame 2 is bolted to the outer frame 3. The fixed frame 2 is used to connect to a vehicle. One side of the inner wall of the outer frame 3 is welded with a support plate 4, and the other side of the inner wall of the outer frame 3 is welded with a limit plate 5. A circular hole is opened on the limit plate 5. The support plate 4 is bolted with a motor 6. A rhombus shaft 7 is welded on the output shaft of the motor 6. The rhombus shaft 7 passes through the circular hole of the limit plate 5. A sponge column 8 is slidably connected to the rhombus shaft 7. The sponge column 8 contacts the top of the rail 1. The sponge column 8 is used to clean the rail 1.

[0019] It also includes a pressing block 9, a pressed block 10 and a compression spring 11. The pressing block 9 is welded to one end of the sponge column 8 close to the motor 6. The support plate 4 is welded with a pressed block 10. The pressing block 9 is used to press the pressed block 10. A compression spring 11 is connected between the end of the sponge column 8 far from the motor 6 and the limit plate 5.

[0020] First, the staff aligns the outer frame 3 with the rail 1, then sets the fixed frame 2 on the vehicle, and then starts the motor 6. While the vehicle is moving, it drives the fixed frame 2, the outer frame 3, the support plate 4, the limit plate 5, the motor 6, the rhombus shaft 7 and the sponge column 8 to move together. The rotation of the output shaft of the motor 6 will drive the rhombus shaft 7 and the sponge column 8 to rotate together. The rotation of the sponge column 8 will clean the dust on the top of the rail 1, so that the rail 1 and the vehicle are in full contact, thereby enabling the rail 1 to transmit electricity more effectively. While the sponge column 8 is rotating, it will drive the pressing block 9 to rotate, so that the pressing block 9 will pass through the pressed block 10, and then drive the sponge column 8 to swing back and forth left and right through the compression spring 11, thereby shaking off the dust attached to the sponge column 8 and cleaning the rail 1 more thoroughly.

[0021] Embodiment 2: On the basis of Embodiment 1, as Figure 2 、 Figure 4 and Figure 5As shown in the figure, it further includes a fixed shaft 12, a large gear 13, a rotating shaft 14, a small gear 15, a bidirectional lead screw 16 and a scraping block 17. The fixed shaft 12 is welded to one end of the rhombic shaft 7 away from the motor 6. A large gear 13 is connected to the fixed shaft 12 by a flat key. A rotating shaft 14 is rotatably connected to the limiting plate 5. The rotating shaft 14 and the fixed shaft 12 are horizontally arranged. A small gear 15 is connected to one side of the rotating shaft 14 by a flat key. The large gear 13 and the small gear 15 are meshed. A bidirectional lead screw 16 is welded to the end of the rotating shaft 14 away from the small gear 15. A scraping block 17 is connected to the bidirectional lead screw 16 by a thread. The scraping block 17 contacts the top of the rail 1. The scraping block 17 is used to scrape off the accumulated dust.

[0022] It further includes a scraping plate 18. The scraping plate 18 is welded to the top inner wall of the outer frame 3. The scraping plate 18 contacts the sponge column 8. The scraping plate 18 is used to scrape the sponge column 8.

[0023] When the sponge column 8 rotates, it will drive the fixed shaft 12 and the large gear 13 to rotate together. The rotation of the large gear 13 will drive the rotating shaft 14 and the bidirectional lead screw 16 to rotate together through the small gear 15. The rotation of the bidirectional lead screw 16 will first drive the scraping block 17 to move along the top of the rail 1 in the direction away from the motor 6. When the bidirectional lead screw 16 continues to rotate, it will drive the scraping block 17 to move along the top of the rail 1 in the direction close to the motor 6. Repeating like this, the rotation of the bidirectional lead screw 16 will drive the scraping block 17 to move left and right reciprocally along the top of the rail 1, thereby scraping off the dust that may accumulate in front of the sponge column 8 onto the rail 1, so as to improve the cleaning efficiency of the sponge column 8 for the rail 1. When the sponge column 8 rotates, it passes through the scraping plate 18, and the scraping plate 18 will indirectly scrape the sponge column 8, thereby scraping off the wet dust that cannot be shaken off on the sponge column 8, so that the sponge column 8 further cleans the rail 1.
