Description

Technical Field

[0001] This invention belongs to the field of asphalt paving technology, specifically an asphalt paving device for narrow cycling paths. Background Technology

[0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a type of high-viscosity organic liquid, which is liquid with a black surface. It is a waterproof, moisture-proof and corrosion-resistant organic cementing material.

[0003] Currently, in the process of paving roads, molten asphalt is generally stored in a storage tank on an asphalt paving truck. As the asphalt paving truck travels on the road to be paved, the asphalt flows out from the storage tank, thus paving the road with asphalt.

[0004] Currently, during the asphalt paving process, sometimes potholes are encountered on the paving surface. This makes it difficult for the asphalt to fill the potholes when passing through them. After paving, the asphalt in the potholes is significantly lower than that on the flat areas, requiring subsequent patching. This reduces the efficiency of asphalt paving, and the bonding between the patched asphalt and the initial asphalt is not as good as that of the initial asphalt, affecting the quality of road paving.

[0005] Therefore, the present invention provides an asphalt paving device for narrow cycling paths. Summary of the Invention

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] Combination Figures 1 to 3 As shown in the embodiment of the present invention, an asphalt paving device for narrow cycling paths includes a frame 1. A storage box 2 is fixedly connected to the middle of the top of the frame 1, and a feed plate 3 is fixedly connected to the rear of the frame 1. A feed pipe 4 is fixedly connected between the feed plate 3 and the storage box 2. A groove 5 is provided at the top of the frame 1 near the feed plate 3. A filling mechanism for filling potholes is provided in the groove 5. A leveling mechanism is provided on the side of the feed plate 3 away from the groove 5. During operation, while paving the cycling path, the storage box 2 stores molten asphalt, the frame 1 travels on the road surface to be paved, and the feed plate 3 lays asphalt on the road surface during the travel of the frame 1. When potholes appear on the road surface, the frame 1 moves the filling mechanism to the top of the pothole, then the frame 1 stops moving, and the material feeding plate 3 stops laying asphalt. The filling mechanism fills the pothole, which is beneficial for filling the pothole. After the pothole is filled, the frame 1 continues to move, and the material feeding plate 3 continues to lay asphalt. During the asphalt laying process by the material feeding plate 3, the leveling mechanism scrapes the asphalt laid on the road surface, which helps to promote the smoothness of the asphalt paving. By setting up the filling mechanism, the asphalt paving efficiency is improved, and manual filling of potholes is avoided. This also prevents the subsequent filling asphalt from being less bonded to the initial asphalt, thus improving the quality of the road paving.

[0032] Combination Figures 2 to 4 As shown, the filling mechanism includes a threaded rod 9 and a motor 10. The threaded rod 9 is rotatably connected within the slide 5. The motor 10 is fixedly connected to the side wall of the frame 1. The rotating shaft of the motor 10 passes through the side wall of the frame 1 and is fixedly connected to the threaded rod 9. A moving block 6 is threadedly connected to the threaded rod 9, and the moving block 6 is slidably connected to the slide 5. A feeding pipe 7 is fixedly connected to the side wall of the moving block 6 near the feeding plate 3. A second feeding pipe 8 is fixedly connected to the top of the feeding pipe 7. The end of the second feeding pipe 8 away from the feeding pipe 7 is fixedly connected to the storage box 2. The bottom of the slide 5... A detection component is provided on the side of the part away from the material feeding plate 3. The detection component is used to detect potholes on the bottom surface. During operation, as the frame 1 moves, the detection component detects the road surface. When a pothole is detected, the motor 10 starts. The rotating shaft of the motor 10 drives the threaded rod 9 to rotate, so that the moving block 6 moves the material filling pipe 7 to directly above the pothole. Then, material is supplied into the material filling pipe 7 through the material supply pipe 8. Asphalt flows from the material filling pipe 7 to the pothole, thus filling the pothole and helping to ensure the integrity of the asphalt paving on the road in conjunction with the material feeding plate 3.

[0033] Combination Figure 2 , Figure 4 and Figure 7 As shown, the detection component includes a mounting plate 11, which is fixedly connected to the bottom of the frame 1. Multiple sets of infrared detectors 12 are evenly and equidistantly fixed to the bottom of the mounting plate 11. During operation, the infrared detectors 12 detect the road surface in real time while the frame 1 is moving. When no potholes are detected, the frame 1 continues to move and the material feeding plate 3 continues to lay asphalt. When a pothole is detected, the motor 10 starts, and the rotating shaft of the motor 10 drives the threaded rod 9 to rotate, so that the moving block 6 drives the material filling pipe 7 to move directly above the pothole, which is beneficial for subsequent material filling of the pothole.

[0034] Combination Figure 4 and Figure 5 As shown, a track plate 13 is fixedly connected to the side of the feeding pipe 7 near the moving block 6. An electric slider 14 is slidably connected to the track plate 13. A support plate 15 is fixedly connected to the side of the electric slider 14 away from the feeding pipe 7. A second groove 16 is opened at the bottom of the support plate 15. A lifting plate 17 is slidably connected in the second groove 16. A pressure sensor 19 is fixedly connected to the top wall of the second groove 16. A float plate 18 is fixedly connected to the bottom of the lifting plate 17. During operation, the rotating shaft of the motor 10 drives the threaded rod 9 to rotate, so that the moving block 6 moves the feeding pipe 7 to directly above the pit. Then, the electric slider 14 is activated, and the electric slider 14 drives the support plate 15 and the lifting plate 17 to move. 7 and float 18 descend, with float 18 placed in the pothole and slightly below the road surface. As the filling pipe 7 fills the pothole with asphalt, the amount of asphalt in the pothole gradually increases. When the asphalt in the pothole comes into contact with float 18, the filling pipe 7 continues to fill the pothole. The asphalt will drive float 18 and lifting plate 17 upward. When lifting plate 17 presses against pressure sensor 19, it indicates that the pothole has been filled and the filling pipe 7 stops filling the pothole. This is beneficial for monitoring the amount of filling in the pothole, for the smooth filling of the pothole, and for avoiding asphalt waste. After the filling stops, electric slider 14 starts to move upward, driving support plate 15 back to its initial position.

[0035] Combination Figure 4 , Figure 7 and Figure 8As shown, a groove 20 is provided on the bottom surface of the frame 1 at the end away from the motor 10. A push rod 21 is slidably connected in the groove 20. A cleaning strip 22 is fixedly connected to the bottom of the push rod 21. Two springs 23 are fixedly connected to the side wall of the cleaning strip 22. The end of the springs 23 near the frame 1 is fixedly connected to the side wall of the frame 1. During operation, after the replenishment pipe 7 and the float 18 have been used multiple times, the threaded rod 9 drives the replenishment pipe 7 and the motor 10 to move to the end of the groove 5 near the groove 20. Then, the push rod 21 can be pushed, so that the push rod 21 drives the cleaning strip 22 to move towards the replenishment pipe 7 and the float 18. The cleaning strip 22 cleans and scrapes off the asphalt remaining at the bottom of the replenishment pipe 7 and the float 18.

[0036] Combination Figure 1 As shown, the leveling mechanism includes a scraper 24, which is rotatably connected to the bottom of the end of the frame 1 near the material plate 3. Two cylinders 25 are rotatably connected to the end of the frame 1 near the material plate 3, and the ends of the telescopic rods of the two cylinders 25 are rotatably connected to the scraper 24. During operation, when the material plate 3 is laying asphalt, the telescopic rods of the cylinders 25 drive the scraper 24 to rotate to a suitable angle, which can level the asphalt laid on the road surface and promote the smoothness of the road.

[0037] Combination Figures 1 to 3 As shown, a blower 29 is fixedly connected to the end of the frame 1 away from the material feed plate 3. An air supply pipe 30 is fixedly connected to the air outlet of the blower 29. The bottom of the air supply pipe 30 passes through the bottom surface of the frame 1 and is fixedly connected to a spray pipe 31. During operation, air is pumped into the air supply pipe 30 by the blower 29. The air passes through the air supply pipe 30 and enters the spray pipe 31 and is sprayed onto the road surface, which helps to blow away debris on the road surface and improves the cleanliness of the asphalt paved road.

[0038] Combination Figures 1 to 3 As shown, a second air supply pipe 32 is fixedly connected to the air outlet of the blower 29. The second air supply pipe 32 is laid on the surface of the frame 1. The end of the second air supply pipe 32 away from the first air supply pipe 30 is placed at the end of the frame 1 near the material plate 3 and is fixedly connected to the second spray pipe 34. During operation, the arrangement of the second air supply pipe 32 and the second spray pipe 34 is beneficial to the cooling of the asphalt after the asphalt is laid on the material plate 3, which is conducive to the rapid cooling and molding of the laid asphalt.

[0039] Combination Figure 6 As shown, a solenoid valve 33 is fixedly connected to one end of the air supply pipe 32 near the nozzle 34. During operation, when the weather temperature is low, the asphalt being laid can cool down and solidify quickly. By setting the solenoid valve 33, the air supply pipe 32 can be blocked, which is conducive to all the air pumped in by the blower 29 being sprayed out from the air supply pipe 32, which is conducive to improving the cleaning efficiency of road debris.

[0040] Combination Figures 1 to 3 As shown, a baffle 26 is fixedly connected to the bottom of the end of the frame 1 away from the feed plate 3. The bottom of the baffle 26 has an insertion groove, and a cleaning plate 27 is slidably connected in the insertion groove. Brush bristles are fixedly connected to the bottom of the cleaning plate 27, and multiple sets of springs 28 are fixedly connected to the top of the cleaning plate 27. The ends of the multiple sets of springs 28 away from the cleaning plate 27 are all fixedly connected to the top wall of the insertion groove. During operation, the setting of the cleaning plate 27 helps to drive the brush bristles to sweep the road surface during the movement of the frame 1. At the same time, through the cooperation of the baffle 26 and the cleaning plate 27, during the process of the nozzle 31 blowing air onto the road surface to clean up debris, it is prevented that debris will be blown to the bottom of the frame 1.

[0041] Working principle: During the paving of the cycling path, the storage box 2 stores molten asphalt, the frame 1 travels on the road surface to be paved, and the feed plate 3 lays asphalt on the road surface while the frame 1 travels. At the same time, the infrared detector 12 detects the road surface in real time. When no potholes are detected, the frame 1 continues to travel and the feed plate 3 continues to lay asphalt.

[0042] When a pothole is detected, the rotating shaft of motor 10 drives the threaded rod 9 to rotate, causing the moving block 6 to move the filling pipe 7 directly above the pothole. Then, the electric slider 14 is activated, which lowers the support plate 15, lifting plate 17, and float plate 18. The float plate 18 is placed inside the pothole and slightly below the road surface. As the filling pipe 7 fills the pothole with asphalt, the amount of asphalt in the pothole gradually increases. When the asphalt in the pothole comes into contact with the float plate 18, the filling pipe 7 continues to fill the pothole. The asphalt will drive the float plate 18 and lifting plate 17 upward. When the lifting plate 17 presses against the pressure sensor 19, it indicates that the pothole has been filled. The filling pipe 7 stops filling the pothole. This is beneficial for monitoring the amount of filling in the pothole, ensuring smooth filling, and avoiding asphalt waste. After the filling stops, the electric slider 14 starts to move upward, causing the support plate 15 to return to its initial position.

[0043] After the feed pipe 7 and float plate 18 have been used multiple times, the threaded rod 9 drives the feed pipe 7 and motor 10 to move to one end of the slide 1 5 near the slide 3 20. Then the push rod 21 can be pushed so that the push rod 21 drives the cleaning strip 22 to move towards the feed pipe 7 and float plate 18. The cleaning strip 22 cleans and scrapes off the asphalt residue at the bottom of the feed pipe 7 and float plate 18.

[0044] After the potholes are filled, the vehicle frame 1 continues to travel, and the material unloading plate 3 continues to lay asphalt.

[0045] During the movement of the vehicle frame 1, the blower 29 pumps air into the air supply pipe 30. The air passes through the air supply pipe 30 and enters the nozzle 31 before being sprayed onto the road surface. This helps to remove debris from the road surface and improves the cleanliness of the asphalt pavement.

[0046] During the movement of the vehicle frame 1, the fan 29 pumps air into the air supply pipe 32, and the air blown out of the air supply pipe 32 cools down the asphalt that has been laid, which is conducive to the rapid cooling and shaping of the laid asphalt.
