Description

Technical Field

[0001] This application relates to the technical field of road construction, and in particular to an asphalt paving device for road construction. Background Technology

[0002] Asphalt paving is a crucial step in road construction. It refers to the process of laying asphalt mixture, which is a mixture of asphalt and aggregate in a certain proportion, on the road base to form a smooth, solid road surface structure with good driving performance.

[0003] The Chinese Patent Network discloses an asphalt paving device for road construction, with publication number CN217896141U. The cleaning mechanism includes a mounting base, with first mounting plates connected to both sides of the bottom of the mounting base. Scrapers are connected to the bottom of the connecting rods on both sides. A pressure roller is connected inside the mounting frame. Threaded holes are provided on both sides of the second mounting plates, and second threaded tubes are screwed into the inside of the threaded holes on both sides. This asphalt paving device for road construction rotates the second threaded tubes on both sides to disengage them from the threaded holes on both sides. At this time, the spring rebound force causes the scraper to move downwards, and the scraper contacts the pressure roller. As the pressure roller rotates, the asphalt adhering to the pressure roller is scraped off by the scraper, making it easy to remove the asphalt adhering to the pressure roller, saving a lot of time and energy, and the cleaning efficiency is very high, without the need for additional tools.

[0004] The following problems exist in this solution: In this solution, the asphalt adhering to the pressure roller is easily removed by contact between the scraper and the pressure roller. However, the efficiency of cleaning by scraper alone is low, and it cannot be completely cleaned. When scraping with the scraper, there may be residues adhering to the pressure roller, which are not easy to remove. Therefore, there are certain drawbacks.

[0005] Therefore, in order to solve the above problems, this application provides an asphalt paving device for road construction. Utility Model Content

[0006] The purpose of this invention is to provide an asphalt paving device for road construction to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an asphalt paving device for road construction, comprising a support platform, with fixed plates symmetrically installed on both sides of one bottom end of the support platform, a pressure roller installed between the outer bottom ends of the fixed plates, a mixing tank installed at one top end of the support platform, a water storage tank installed near the mixing tank at the top of the support platform, a fixed frame installed at the bottom of the support platform, a groove formed on the inner top of the fixed frame, a threaded rod installed between the inner walls of the groove, a movable block installed on the outer ring surface of the threaded rod, an adjusting rod installed at the bottom of the movable block, an adjusting plate installed at the bottom end of the adjusting rod and on the inner wall of the fixed frame, a diversion pipe installed on the outer surface of the adjusting plate, and several sets of spray heads installed at equal intervals along the length direction on the outer ring surface of the diversion pipe.

[0008] Preferably, a limiting groove is formed on the outer side of the fixed plate, a cylindrical block is provided inside the limiting groove, a movable plate is installed between the outer sides of the cylindrical block, a scraper is installed at the bottom of the movable plate, and fixed frames are symmetrically installed at both ends of the top of the movable plate. A return spring is installed on one side wall of the inner side of the fixed frame, a slider is installed at one end of the return spring and inside the fixed frame, a connecting rod is installed on the top of the slider, and a connecting plate is installed on the top of the connecting rod.

[0009] Preferably, an electric telescopic rod is installed at the top of the support platform away from the mixing tank. The bottom movable end of the electric telescopic rod passes through the support platform and is connected to the top of the connecting plate. Both ends of the connecting rod are rotatably connected to the movable plate and the connecting plate.

[0010] Preferably, a servo motor is installed at one external end of the fixed frame, the output shaft of the servo motor passes through the interior of the slide groove and is connected to one end of the threaded rod, both ends of the adjusting rod are rotatably connected to the movable block and the adjusting plate, and one external end of the adjusting plate is rotatably connected to the fixed frame.

[0011] Preferably, a water pump is installed at one end of the external side of the water storage tank, and a water delivery pipe is installed at the output end of the water pump, with one end of the water delivery pipe connected to a branch pipe.

[0012] Preferably, a support frame is installed at the bottom of the support platform away from the two fixed plates, and rollers are installed at the bottom of the support frame. A traction ring is installed at the outer end of the support platform, and a discharge pipe is installed at the bottom of the support platform and below the mixing tank.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] This is an asphalt paving device for road construction. The telescopic movement of the electric telescopic rod drives the connecting plate to move up and down. In turn, the connecting rod pulls or pushes the movable plate to slide in the limiting groove, thereby adjusting the height of the scraper. This makes it easier to bring the scraper close to the pressure roller to scrape off the asphalt adhering to its surface. A servo motor drives the threaded rod to rotate, causing the movable block to move back and forth in the sliding groove. The rotational connection design of the adjusting rod allows the movement of the movable block to be converted into an angle change of the adjusting plate, thereby adjusting the spray direction of the diversion pipe and the spray head. The water pump draws water from the water tank, delivers water to the diversion pipe through the water pipe, and then sprays it evenly onto the pressure roller by the spray head. This allows for easy adjustment of the appropriate angle to clean the outside of the pressure roller, avoiding the possibility of residue sticking to the pressure roller during scraping, which is difficult to scrape off. The device is convenient to operate and has better practicality. Attached Figure Description

[0022] An asphalt paving device for road construction, referring to Figure 1 - Figure 5The system includes a support platform 1, with fixed plates 2 symmetrically installed on both sides of the bottom end of the support platform 1, pressure rollers 3 installed between the bottom ends of the outer sides of the fixed plates 2, a mixing tank 4 installed at the top end of the support platform 1, a water storage tank 5 installed near the mixing tank 4 at the top of the support platform 1, a fixed frame 6 installed at the bottom of the support platform 1, a sliding groove 601 opened on the top inner side of the fixed frame 6, a threaded rod 7 installed between the inner side walls of the sliding groove 601, a movable block 8 installed on the outer ring surface of the threaded rod 7, an adjusting rod 9 installed at the bottom of the movable block 8, an adjusting plate 10 installed at the bottom end of the adjusting rod 9 and on the inner side wall of the fixed frame 6, a diversion pipe 11 installed on the outer side surface of the adjusting plate 10, and several sets of spray heads 12 installed at equal intervals along the length direction on the outer ring surface of the diversion pipe 11.

[0023] Reference Figure 1 - Figure 4 Limiting grooves 201 are formed on the outer surface of the fixed plate 2. A cylindrical block 13 is set inside the limiting groove 201. A movable plate 14 is installed between the outer surfaces of the cylindrical blocks 13. A scraper 1401 is installed at the bottom of the movable plate 14. Fixed frames 15 are symmetrically installed at both ends of the top of the movable plate 14. A return spring 16 is installed on one side wall of the inner side of the fixed frame 15. A slider 17 is installed at one end of the return spring 16 and inside the fixed frame 15. A connecting rod 18 is installed on the top of the slider 17. A connecting plate 19 is installed on the top of the connecting rod 18. The movable plate 14 slides up and down in the limiting groove 201 through the cylindrical blocks 13. The scraper 1401 is in close contact with the surface of the road surface or the pressure roller 3 to scrape off the outer surface. The design of the return spring 16 and slider 17 gives the scraper 1401 a certain degree of elasticity, preventing damage to the scraper 1401. An electric telescopic rod 20 is installed at the top of the support platform 1 away from the mixing tank 4. The bottom movable end of the electric telescopic rod 20 passes through the support platform 1 and is connected to the top of the connecting plate 19. Both ends of the connecting rod 18 are rotatably connected to the movable plate 14 and the connecting plate 19. The telescopic movement of the electric telescopic rod 20 drives the connecting plate 19 to move up and down, and then the connecting rod 18 pulls or pushes the movable plate 14 to slide in the limiting groove 201, realizing the adjustment of the height of the scraper 1401, which makes it easy to bring the scraper 1401 close to the pressure roller 3 to scrape off the asphalt adhering to its surface.

[0024] Reference Figure 1 - Figure 5A servo motor 701 is mounted on one end of the fixed frame 6. The output shaft of the servo motor 701 passes through the interior of the slide groove 601 and is connected to one end of the threaded rod 7. Both ends of the adjusting rod 9 are rotatably connected to the movable block 8 and the adjusting plate 10, and the outer end of the adjusting plate 10 is rotatably connected to the fixed frame 6. The servo motor 701 drives the threaded rod 7 to rotate, thereby causing the movable block 8 to move back and forth in the slide groove 601. The rotatable connection design of the adjusting rod 9 allows the movement of the movable block 8 to be converted into an angle change of the adjusting plate 10. This allows for adjustment of the water spray direction of the diversion pipe 11 and the spray head 12, facilitating the adjustment of the appropriate angle for cleaning the exterior of the pressure roller 3. This prevents residue from sticking to the pressure roller 3 during scraping by the scraper 1401, which would make it difficult to remove. A water pump 21 is installed at one end of the exterior of the water storage tank 5, and a water delivery pipe 22 is installed at the output end of the water pump 21. One end of the water delivery pipe 22 is connected to the diversion pipe 11. The water pump 21 draws water from the water storage tank 5, delivers the water to the diversion pipe 11 through the water delivery pipe 22, and then sprays it evenly onto the pressure roller 3 by the spray head 12.

[0025] Reference Figure 1 - Figure 2 A support frame 23 is installed at the bottom of the support platform 1 away from the two fixed plates 2. Rollers 24 are installed at the bottom of the support frame 23. A traction ring 25 is installed at the outer end of the support platform 1. A discharge pipe 26 is installed at the bottom of the support platform 1 and below the mixing tank 4. The design of the support frame 23 and the rollers 24 makes the device easy to move on the road. The traction ring 25 is used to connect to a traction vehicle to realize the traction movement of the device. The discharge pipe 26 is used to evenly spread the asphalt mixture mixed in the mixing tank 4 onto the road surface, thus completing the main task of asphalt paving.

[0026] The implementation principle of an asphalt paving device for road construction according to an embodiment of this application is as follows: When using the device, the design of the support frame 23 and rollers 24 allows the device to move easily on the road. The traction ring 25 is used to connect to a traction vehicle to achieve traction movement of the device. The discharge pipe 26 is used to evenly spread the asphalt mixture mixed in the mixing tank 4 onto the road surface, completing the main task of asphalt paving. The telescopic movement of the electric telescopic rod 20 drives the connecting plate 19 to move up and down, and then pulls or pushes the movable plate 14 to slide in the limiting groove 201 through the connecting rod 18, realizing the adjustment of the height of the scraper 1401, which makes it easy to bring the scraper 1401 close to the pressure roller 3 to scrape off the asphalt adhering to its surface. The movable plate 14 slides up and down in the limiting groove 201 through the cylindrical block 13, and the scraper 1401 is in close contact with the road surface or The surface of the pressure roller 3 is used to scrape off the asphalt adhering to its exterior. The design of the return spring 16 and the slider 17 gives the scraper 1401 a certain degree of elasticity, preventing damage to the scraper 1401. The servo motor 701 drives the threaded rod 7 to rotate, thereby causing the movable block 8 to move back and forth in the slide groove 601. The rotational connection design of the adjusting rod 9 allows the movement of the movable block 8 to be converted into an angle change of the adjusting plate 10, thereby adjusting the spray direction of the diversion pipe 11 and the spray head 12. The water pump 21 draws water from the water storage tank 5 and delivers the water to the diversion pipe 11 through the water supply pipe 22. Then, the water is evenly sprayed onto the pressure roller 3 by the spray head 12, which facilitates the adjustment of the appropriate angle to clean the exterior of the pressure roller 3. This avoids the possibility of residue sticking to the pressure roller 3 when the scraper 1401 is scraping, which is not easy to scrape off. The operation is convenient and the practicality is better.
