Description

Technical Field

[0001] This invention relates to the field of coke oven small furnace door inspection technology, specifically to an automated inspection track for coke oven small furnace doors. Background Technology

[0002] The coke oven is a core piece of equipment in steel production. Its small furnace doors (usually ranging from dozens to hundreds) are distributed on both sides of the coke oven body, responsible for controlling the heating and gas flow. The sealing performance and surface condition of the small furnace doors directly affect the thermal efficiency and safe production of the coke oven, therefore, regular inspections are necessary.

[0003] Traditional manual inspections pose high safety risks. The high surface temperature of the coke oven makes manual inspections prone to burns, gas poisoning, and other accidents. Furthermore, inspection efficiency is low, with densely packed small oven doors leading to long inspection times. Data accuracy is also poor, as manual inspection relies on subjective judgment and easily misses minor defects. While automated inspection equipment effectively solves these problems, existing inspection tracks experience thermal expansion under the continuous high temperatures of the coke oven. The existing steel tracks lack thermal compensation structures, making them prone to bending and twisting, causing the inspection equipment to jam or derail. The large amounts of coal dust and coke dust generated during coke oven production easily accumulate on the track surface. The existing tracks lack cleaning devices, and the dust reduces the friction between the robot's wheels and the track, causing slippage. Simultaneously, dust entering the track connection gaps accelerates component corrosion. Summary of the Invention

[0004] The purpose of this invention is to provide an automated inspection track for small coke oven doors to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An automated inspection track for a small coke oven door includes: The track assembly includes multiple main tracks, which are installed inside the coke oven via lifting brackets and are fixed to the lifting brackets with bolts. Adjacent main tracks are connected by a connecting mechanism, which provides a dynamic seal with the main tracks and is capable of compensating for temperature differences in the main tracks. The cleaning assembly includes at least two cleaning components, each located at one end of the track assembly. Each cleaning assembly includes a movable frame with two symmetrically arranged mounting brackets on its upper end. Each mounting bracket has a rotatable roller connected to a drive motor, and the lower end of each roller is attached to the middle of the main track. The upper end of the cleaning assembly is equipped with a cleaning mechanism for removing dust and tar from the middle of the main track. The lower end of the movable frame is equipped with a scraping mechanism for scraping off dust and tar from the lower surface of the main track.

[0006] As mentioned above, the main track is an I-beam, and heat dissipation holes are evenly provided on the vertical section and the two horizontal sections of the main track.

[0007] As described above, the connecting mechanism includes two clamping plates, which are fixed together by bolts. The end of the main track is provided with a connecting part, and the main track is installed in the clamping plate through the connecting part. A sealing element is provided between the edge of the clamping plate and the mounting part.

[0008] As described above, the clamping plate includes a vertical plate, and two horizontal plates are arranged side by side at both ends of the vertical plate. The opposite sides of the horizontal plates are flush with the outline plane of the main track. Two guide posts are arranged side by side on the opposite sides of the two horizontal plates and on the side of the vertical plate away from the horizontal plates. A guide groove is provided at the corresponding position of the connecting part. The guide posts are slidably disposed in the guide groove. The connecting part is disposed between the two horizontal plates. A reinforcing rib is provided in the middle of the two horizontal plates. Multiple rollers are provided on the opposite sides of the two horizontal plates and on the side of the clamping plate away from the horizontal plates.

[0009] As mentioned above, the outer side of the roller is provided with anti-slip patterns.

[0010] The cleaning mechanism described above includes two scrapers, which are rotatably and symmetrically mounted on the mounting frame. A roller brush is disposed between the scraper and the roller, and the roller brush is rotatably mounted on the mounting frame. A gear is disposed at one end of the roller brush and at the output end of the drive motor. The gears on the roller brush mesh with the gears at the output end of the drive motor, and the lower end of the roller brush is attached to the upper end of the horizontal section of the main track.

[0011] As described above, an arc-shaped plate is also provided on the side of the scraper away from the roller brush, and the lower end of the arc-shaped plate and the lower end of the scraper are both attached to the upper end of the horizontal section of the main track.

[0012] As described above, a baffle is provided at one end of the arc-shaped plate near the roller brush, and the edge of the baffle is provided with comb teeth, and the baffle is in close contact with the outside of the roller brush through the comb teeth.

[0013] As described above, the shovel mechanism includes two fixed rods, which are symmetrically arranged on the lower side of the movable frame. A shovel plate is slidably arranged on the end of the fixed rod away from the movable frame. A return spring is arranged between the shovel plate and the fixed rod. Two guide rods are symmetrically arranged on the end of the shovel plate facing the movable frame. The guide rods are slidably arranged on the movable frame.

[0014] In the above technical solution, the beneficial effects of the present invention are as follows: 1. This invention uses multiple main tracks spliced ​​together to form a complete track, so as to divide the deformation of the track and avoid excessive deformation of the overall track. Furthermore, the adjacent main tracks are connected by a connection mechanism to achieve dynamic sealing and temperature difference compensation simultaneously. The dynamic seal prevents dust or tar from entering the connection, reducing the occurrence of rust. The temperature difference compensation of the connection mechanism can offset the track expansion and contraction caused by temperature changes, ensuring track continuity and ensuring that the inspection equipment and cleaning components can operate stably on the track. This invention uses a drive motor to rotate the rollers, causing the mobile frame to move bidirectionally along the middle of the main track. This allows the cleaning mechanism at the upper end of the mobile frame to remove dust or tar from the middle of the main track, while the scraping mechanism at the lower end of the mobile frame cleans the scale buildup on the lower surface of the main track, achieving unmanned cleaning. The cleaning covers areas prone to scale buildup, preventing scale buildup from affecting the walking mechanism, rollers, or corroding the track of the inspection equipment. This invention provides a reliable path for the cleaning component through the stable and continuous operation of the track component, while the regular cleaning of the cleaning component in turn ensures that the track is free from dirt accumulation and damage, maintains the long-term operation of the system, ensures the stable operation of the inspection equipment, realizes the automation and high reliability of the inspection of the small coke oven door, and improves the inspection efficiency.

[0018] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0019] In the description of this invention, it should be understood that the terms "upper", "lower", "vertical", "horizontal", "side", "inner", "outer", "one end", "the other end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0020] like Figures 1-8 As shown in the figure, an automated inspection track for a small coke oven door provided in this embodiment of the invention includes: Track assembly 1 includes multiple main tracks 10, which are installed inside the coke oven by a hoisting bracket and are fixed to the hoisting bracket by bolts. Two adjacent main tracks 10 are connected by a connecting mechanism 11, which provides a dynamic seal with the main track 10 and is capable of compensating for temperature differences in the main track 10. The cleaning assembly 2, having at least two components, is located at both ends of the track assembly 1. Each cleaning assembly 2 includes a movable frame 20 with two symmetrically arranged mounting brackets 21 on its upper end. Each mounting bracket 21 has a rotatable roller 22 connected to a drive motor 23. The lower end of each roller 22 is attached to the middle of the main track 10. A cleaning mechanism 24 is provided at the upper end of the cleaning assembly 2 for removing dust and tar from the middle of the main track 10. A scraping mechanism 25 is provided at the lower end of the movable frame 20 for scraping dust and tar from the lower surface of the main track 10. The specific implementation method is as follows: When the inspection track is installed inside the coke oven, the hoisting bracket is first installed inside the coke oven. Then, multiple main tracks 10 are installed at the lower end of the hoisting bracket by bolts, so that the multiple main tracks 10 are in a straight line, and adjacent main tracks 10 are connected by a connecting mechanism 11. After the track assembly 1 is installed, two cleaning components 2 are installed at both ends of the track assembly 1. After the cleaning components 2 are installed, the inspection equipment is installed on the track assembly 1, with the inspection equipment positioned between the two cleaning components 2. In this way, when the coke oven is working, the inspection equipment is used to inspect and observe the small furnace doors of the coke oven. During the coke oven production process, a large amount of coal dust and coke dust are generated, which easily accumulate on the surface of the main track 10. The dust will reduce the inspection equipment's efficiency. The friction between the traveling mechanism and the main track 10 causes slippage. At the same time, dust entering the connection gaps of the main track 10 accelerates the corrosion rate, and the generated tar will stick the dust to the surface of the main track 10, causing the inspection equipment to shake when moving along the track assembly 1. At this time, the drive motor 23 drives the roller 22 to rotate, so that the roller 22 drives the moving frame 20 to move along the main track 10 through the mounting frame 21. This causes the moving frame 20 to drive the cleaning mechanism 24 and the scraping mechanism 25 to move along the main track 10, so that the cleaning mechanism 24 and the scraping mechanism 25 can clean the dust and tar on the surface of the main track 10, reduce or even avoid the slippage of the traveling mechanism of the inspection equipment when moving along the main track 10, and ensure the normal operation of the inspection equipment.

[0021] In another embodiment of the present invention, the main track 10 is an I-beam, and heat dissipation holes are uniformly provided on the vertical section and the two horizontal sections of the main track 10. The specific implementation method is as follows: the main track 10 is an I-beam to facilitate the installation of inspection equipment and cleaning components 2, and the I-beam has good rigidity to prevent the track components 1 from deforming during use. In addition, the heat dissipation holes evenly provided on the vertical and horizontal sections of the main track 10, i.e. the I-beam, enhance air convection and reduce the temperature of the main track 10, thereby reducing or even avoiding the deformation of the main track 10 due to temperature difference.

[0022] In another embodiment of the present invention, the connecting mechanism 11 includes two clamping plates 110, which are fixed together by bolts. The end of the main track 10 is provided with a connecting part 101. The main track 10 is installed in the clamping plate 110 through the connecting part 101. A sealing element is provided between the clamping plate 110 and the edge of the mounting part. The specific implementation is as follows: the connecting part 101 is provided at the end of the main track 10. When the main track 10 is installed, the connecting part 101 at its end connects two adjacent main tracks 10. The connecting part 101 provides the installation position of the clamping plate 110, ensuring that the surfaces of the two adjacent main tracks 10 are flat and aligned when they are connected and fixed by the clamping plate 110. This ensures that the inspection equipment and the roller 22 can pass smoothly and easily through the connection of the two adjacent main tracks 10. The gap between the clamping plate 110 and the connecting part 101 is sealed by the sealing element to prevent dust from entering between the clamping plate 110 and the connecting part 101 and accelerating the corrosion rate of both.

[0023] In another embodiment of the present invention, the clamping plate 110 includes a vertical plate 1100, and two horizontal plates 1101 are arranged side by side at both ends of the vertical plate 1100. The opposite sides of the horizontal plates 1101 are flush with the contour plane of the main track 10. Two guide posts 1102 are arranged side by side on the opposite sides of the two horizontal plates 1101 and on the side of the vertical plate 1100 away from the horizontal plates 1101. A guide groove 1010 is provided at the corresponding position of the connecting part 101. The guide posts 1102 are slidably disposed in the guide groove 1010. The connecting part 101 is disposed between the two horizontal plates 1101. A reinforcing rib 1103 is provided in the middle of the two horizontal plates 1101. Multiple rollers are provided on the opposite sides of the two horizontal plates 1101 and on the side of the clamping plate 110 away from the horizontal plates 1101. The specific implementation method is as follows: During the installation of the main track 10, the connecting parts 101 of two adjacent main tracks 10 are connected by two clamping plates 110. First, two vertical plates 1100 are pre-connected by bolts, so that the two vertical plates 1100 are combined into a whole by bolts. Then, the vertical section of the main track 10 is inserted between the two vertical plates 1100. At the same time, the two horizontal sections of the main track 10 are inserted between the horizontal plates 1101 along with the vertical section. When the main track 10 is inserted between the two clamping plates 110, the main track 10 drives the guide grooves 1010 on its connecting parts 101 to approach the corresponding guide posts 1102, so that the guide posts 1102 are in the guide grooves 101. After the main track 10 is inserted between the two clamping plates 110, the bolts are tightened so that the two clamping plates 110 connect and fix the connecting parts 101 of the two adjacent main tracks 10, so that the two adjacent main tracks 10 are connected into a whole, which facilitates the movement of the inspection equipment and the cleaning component 2 along the main track 10; the guide column 1102 and the guide groove 1010 allow the main track 10 to deform and extend in its length direction due to temperature difference, and effectively limit the movement and deformation of the main track 10 perpendicular to its length; the reinforcing rib 1103 is used to increase the strength of the horizontal plate 1101; the roller can reduce the friction between the connecting part 101 and the clamping plate 110, which facilitates the movement of the main track 10 within the clamping plate 110 when it is deformed by heat.

[0024] In another embodiment of the present invention, the outer side of the roller 22 is provided with an anti-slip pattern; The specific implementation method is as follows: the anti-slip pattern on the outer side of the roller 22 can effectively increase the friction between the roller 22 and the main track 10, and prevent the roller 22 from slipping when there is dust on the main track 10. This ensures that the roller 22 can drive the cleaning mechanism 24 and the shovel mechanism 25 to move stably along the main track 10 through the moving frame 20, so that the cleaning mechanism 24 and the shovel mechanism 25 can clean the dust on the main track 10.

[0025] In another embodiment of the present invention, the cleaning mechanism 24 includes two scrapers 240, which are rotatably and symmetrically arranged on the mounting frame 21. A roller brush 242 is arranged between the scraper 240 and the roller 22. The roller brush 242 is rotatably arranged on the mounting frame 21, and a gear 243 is provided at one end of the roller brush 242 and at the output end of the drive motor 23. The gears 243 on the roller brush 242 mesh with the gears 243 at the output end of the drive motor 23, and the lower end of the roller brush 242 is attached to the upper end of the horizontal section of the main track 10. The specific implementation method is as follows: When the drive motor 23 drives the movable frame 20 to move along the main track 10 through the roller 22, the movable frame 20 drives the scraper 240 to move synchronously, so that the scraper 240 scrapes off the dust on the main track 10 when it moves. When the scraper 240 scrapes off the dust on the main track 10, the drive motor 23 drives the roller brush 242 in the forward direction to rotate through the meshing gear 243, so that the rotated roller brush 242 rotates and cleans the dust scraped off by the scraper 240. In addition, the drive motor 23 drives the roller brush 242 on the other side of the movable frame 20 to rotate through the meshing gear 243, so that the roller brush 242 on the other side of the movable frame 20 rotates and cleans the main track 10 again, ensuring that the dust can be fully swept away from the main track 10 by the roller brush 242. In addition, when the roller brush 242 rotates, it can clean the surface of the roller 22, ensuring that the roller 22 rotates stably.

[0026] In another embodiment of the present invention, an arc-shaped plate 244 is provided on the side of the scraper 240 away from the roller brush 242, and the lower end of the arc-shaped plate 244 and the lower end of the scraper 240 are both attached to the upper end of the horizontal section of the main track 10. The specific implementation method is as follows: when the drive motor 23 drives the moving frame 20 to move along the main track 10 through the roller 22, the moving frame 20 drives the scraper 240 to move synchronously, so that the scraper 240 scrapes off the dust on the main track 10 when it moves. At the same time, the dust scraped off by the scraper 240 can be transported to the outside of the main track 10 through the arc plate 244 on it, so as to avoid the accumulation of dust on the main track 10.

[0027] In another embodiment of the present invention, a baffle 245 is provided at one end of the arc plate 244 near the roller brush 242, and a comb tooth 2450 is provided on the edge of the baffle 245. The baffle 245 is in close contact with the outside of the roller brush 242 through the comb tooth 2450. The specific implementation method is as follows: When the drive motor 23 drives the roller brush 242 to rotate through the meshing gears 243, the rotated roller brush 242 can be combed by the comb teeth 2450 on the edge of the baffle 245. At the same time, the comb teeth 2450 can scrape off the dust stuck on the roller brush 242, so that the roller brush 242 always maintains its own clean state when rotating and cleaning, so that the self-cleaned roller brush 242 can rotate and clean the dust scraped off by the scraper 240, ensuring the cleaning effect of the roller brush 242.

[0028] In another embodiment of the present invention, the shovel mechanism 25 includes two fixed rods 250, which are symmetrically arranged on the lower side of the movable frame 20. A shovel plate 251 is slidably arranged on the end of the fixed rod 250 away from the movable frame 20. A return spring 252 is arranged between the shovel plate 251 and the fixed rod 250. Two guide rods 253 are symmetrically arranged on the end of the shovel plate 251 facing the movable frame 20. The guide rods 253 are slidably arranged on the movable frame 20. The specific implementation method is as follows: When the drive motor 23 drives the movable frame 20 to move along the main track 10 via the roller 22, the movable frame 20 drives the fixed rod 250 to move synchronously, so that the fixed rod 250 drives the scraper plate 251 to move together with the movable frame 20. This allows the scraper plate 251 to scrape off the dust and tar at the lower end of the main track 10. When the fixed rod 250 drives the scraper plate 251 to move with the movable frame 20, the scraper plate 251 can move along the fixed rod 250 and squeeze the return spring 252, so that the scraper plate 251 temporarily moves away from the lower end of the main track 10. This allows the scraper plate 251 to give way when it encounters dust or tar that is difficult to scrape off, thus avoiding difficulty in scraping. To prevent dust or tar from jamming the shovel plate 251 and damaging the drive motor 23, when the shovel plate 251 passes over dust or tar that is difficult to remove, the return spring 252 presses the shovel plate 251, causing the shovel plate 251 to move in the opposite direction along the fixed rod 250 to reset, so that the shovel plate 251 can re-fit against the lower end of the main track 10 and continue to move with the moving frame 20, so that the shovel plate 251 can continue to remove dust or tar from the lower end of the main track 10. When the shovel plate 251 moves along the fixed rod 250, the shovel plate 251 drives the guide rod 253 to slide along the moving frame 20, so that the guide rod 253 guides and limits the shovel plate 251 during movement.

[0029] Working principle: When the inspection track is installed inside the coke oven, the hoisting bracket is first installed inside the coke oven. Then, multiple main tracks 10 are installed at the lower end of the hoisting bracket by bolts, so that the multiple main tracks 10 are in a straight line, and adjacent main tracks 10 are connected by a connecting mechanism 11. The connecting part 101 is located at the end of the main track 10. Thus, when the main track 10 is installed, adjacent main tracks 10 are connected by the connecting part 101 at its end. The connecting part 101 provides the installation position for the clamping plate 110, ensuring that the surfaces of adjacent main tracks 10 are flat and aligned when they are connected and fixed by the clamping plate 110, thereby ensuring that the inspection equipment and the roller 22 can... The main track 10 passes smoothly and easily through the connection between two adjacent main tracks 10, and the gap between the clamping plate 110 and the connecting part 101 is sealed by a sealant to prevent dust from entering between the clamping plate 110 and the connecting part 101 and accelerating their corrosion. During the installation of the main track 10, the connecting parts 101 of two adjacent main tracks 10 are connected by two clamping plates 110. First, the two vertical plates 1100 are pre-connected by bolts, so that the two vertical plates 1100 are combined into a whole by bolts. Then, the vertical section of the main track 10 is inserted between the two vertical plates 1100, and at the same time, the two horizontal sections of the main track 10 are inserted synchronously with the vertical section. When the main track 10 is inserted between the two clamping plates 1101, the main track 10 drives the guide groove 1010 on its connecting part 101 to approach the corresponding guide post 1102, so that the guide post 1102 slides in the guide groove 1010. After the main track 10 is inserted between the two clamping plates 110, the bolts are tightened so that the two clamping plates 110 connect and fix the connecting parts 101 of the two adjacent main tracks 10, so that the two adjacent main tracks 10 are connected into a whole, which facilitates the movement of the inspection equipment and the cleaning component 2 along the main track 10; the guide post 1102 and the guide groove 1012 allow the main track 10 to change along its length due to the temperature difference. The main track 10 is extended in shape and effectively restricts its movement and deformation perpendicular to its length. The reinforcing rib 1103 is used to increase the strength of the horizontal plate 1101. The roller can reduce the friction between the connecting part 101 and the clamping plate 110, and facilitate the movement of the main track 10 within the clamping plate 110 when it is deformed by heat. The main track 10 is made of I-beam, which facilitates the installation of inspection equipment and cleaning components 2. The I-beam has good rigidity to prevent deformation of the track components 1 during use. In addition, the heat dissipation holes evenly provided on the vertical and horizontal sections of the main track 10, i.e. the I-beam, enhance air convection and reduce the temperature of the main track 10, thereby reducing or even avoiding deformation of the main track 10 due to temperature difference. After the track assembly 1 is installed, two cleaning components 2 are installed at both ends of the track assembly 1. After the cleaning components 2 are installed, the inspection equipment is installed on the track assembly 1, positioned between the two cleaning components 2. Thus, during coke oven operation, the inspection equipment is used to inspect and observe the small oven doors. During coke oven production, a large amount of coal dust and coke dust are generated, which easily accumulates on the surface of the main track 10. This dust reduces the friction between the traveling mechanism of the inspection equipment and the main track 10, leading to slippage. The anti-slip pattern on the outer side of the roller 22 effectively increases the friction between the roller 22 and the main track 10, preventing slippage when dust is present on the main track 10 and ensuring the roller... The 22 can drive the cleaning mechanism 24 and the shovel mechanism 25 to move stably along the main track 10 via the movable frame 20, thereby enabling the cleaning mechanism 24 and the shovel mechanism 25 to clean the dust on the main track 10. At the same time, dust entering the connecting gaps of the main track 10 accelerates the corrosion rate, and the generated tar will stick the dust to the surface of the main track 10, causing the inspection equipment to shake when moving along the track assembly 1. At this time, the drive motor 23 drives the roller 22 to rotate, so that the roller 22 drives the movable frame 20 to move along the main track 10 via the mounting frame 21. This causes the movable frame 20 to drive the cleaning mechanism 24 and the shovel mechanism 25 to move along the main track 10, so that the cleaning mechanism 24 and the shovel mechanism 25 can clean the dust on the main track 10. The dust and tar on the surface of the main track 10 are cleaned to reduce or even avoid slippage of the inspection equipment's walking mechanism when moving along the main track 10, ensuring the normal operation of the inspection equipment. When the drive motor 23 drives the moving frame 20 to move along the main track 10 via the roller 22, the moving frame 20 drives the scraper 240 to move synchronously, so that the scraper 240 scrapes off the dust on the main track 10. While the scraper 240 is scraping off the dust on the main track 10, the drive motor 23 drives the forward-moving roller brush 242 to rotate via the meshing gear 243, so that the rotated roller brush 242 rotates and cleans the dust scraped off by the scraper 240. In addition, the drive motor 23 drives the roller brush 242 to rotate via the meshing gear 243. The roller brush 242 on the other side of the movable frame 20 rotates, causing the roller brush 242 on the other side of the movable frame 20 to rotate and clean the main track 10 again, ensuring that the dust can be fully swept away from the main track 10 by the roller brush 242. In addition, when the roller brush 242 rotates, it can clean the surface of the roller 22, ensuring that the roller 22 rotates stably. When the drive motor 23 drives the movable frame 20 to move along the main track 10 through the roller 22, the movable frame 20 drives the scraper 240 to move synchronously, so that the scraper 240 scrapes away the dust on the main track 10 when it moves. At the same time, the dust scraped off by the scraper 240 can be transported to the outside of the main track 10 through the arc plate 244 on it, avoiding the accumulation of dust on the main track 10.When the drive motor 23 drives the roller brush 242 to rotate through the meshing gears 243, the rotated roller brush 242 can be combed by the comb teeth 2450 on the edge of the baffle 245. At the same time, the comb teeth 2450 can scrape off the dust stuck on the roller brush 242, so that the roller brush 242 always keeps itself clean when it rotates to clean, so that the self-cleaned roller brush 242 can rotate to clean the dust scraped off by the scraper 240, ensuring the cleaning effect of the roller brush 242. When the drive motor 23 drives the movable frame 20 to move along the main track 10 via the roller 22, the movable frame 20 drives the fixed rod 250 to move synchronously, causing the fixed rod 250 to drive the scraper plate 251 to move together with the movable frame 20. This allows the scraper plate 251 to scrape away the dust and tar at the lower end of the main track 10. When the fixed rod 250 drives the scraper plate 251 to move with the movable frame 20, the scraper plate 251 can move along the fixed rod 250 and squeeze the return spring 252, causing the scraper plate 251 to temporarily move away from the lower end of the main track 10. This allows the scraper plate 251 to give way when it encounters dust or tar that is difficult to remove, thus preventing the removal of difficult-to-remove dust or tar. Dust or tar can jam the shovel plate 251, preventing damage to the drive motor 23. When the shovel plate 251 passes over dust or tar that is difficult to remove, the return spring 252 presses the shovel plate 251, causing the shovel plate 251 to move in the opposite direction along the fixed rod 250 to reset. This allows the shovel plate 251 to re-adhere to the lower end of the main track 10 and continue to move with the moving frame 20, so that the shovel plate 251 can continue to remove dust or tar from the lower end of the main track 10. When the shovel plate 251 moves along the fixed rod 250, the shovel plate 251 drives the guide rod 253 to slide along the moving frame 20, thereby guiding and limiting the movement of the shovel plate 251.
