AI Technical Summary
During asphalt paving, the temperature of the compaction roller is lower than that of the asphalt mixture, causing the asphalt to easily adhere to the roller surface, affecting the anti-skid performance of the road surface. In addition, the surface of traditional steel wheels is rough or not thoroughly cleaned, which leads to increased asphalt adhesion, filling the gaps between aggregates and reducing the performance of the road surface.
An asphalt adhesion detection component is used to detect asphalt on the surface of the compaction roller. An anti-adhesion agent is sprayed by an anti-adhesion agent spraying component to form a protective film, reducing the viscosity of the asphalt and causing the adhered asphalt to be shaken off. A low-friction film is also formed on the surface of the compaction roller to prevent asphalt adhesion.
It effectively prevents asphalt from adhering to the compaction roller, maintains the anti-skid performance of the road surface, and avoids asphalt adhering to the compaction roller, which would affect the paving quality.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of asphalt paving technology for highway bridges, and in particular to an asphalt paving device for highway bridges. Background Technology
[0002] Asphalt is used in the construction of highway bridges because asphalt mixtures (composed of asphalt, aggregates, mineral powder, etc.) have viscoelastic properties, which can effectively absorb the stress generated by vehicle loads. When vehicles are driving, the asphalt pavement can buffer the impact through the micro-deformation of the material, reduce the rigid collision between the wheels and the road surface, reduce tire wear and vehicle bumps. Compared with rigid cement concrete pavement, asphalt pavement has a lower elastic modulus and is more suitable for frequently bearing heavy traffic loads.
[0003] When laying asphalt, an asphalt paving device is required to transport the asphalt to the highway bridge. The asphalt is then smoothed by a scraper and compressed by a compaction roller. During the compaction process, the movement of the aggregate particles squeezes the asphalt binder, causing it to evenly coat the aggregate surface and fill the pores, forming an asphalt film. Moreover, the uniform distribution of asphalt can enhance the adhesion between aggregates and prevent aggregate peeling caused by water penetration.
[0004] However, when the paving device compacts the asphalt, the temperature of the compaction roller is lower than that of the asphalt mixture. When in contact, the high-temperature asphalt easily adheres to the low-temperature roller surface. Moreover, the surface of the traditional steel wheel is rough or not thoroughly cleaned, and the rubber wheel material has poor compatibility with the asphalt, resulting in increased adhesion. Furthermore, the adhered asphalt will fill the gaps between the aggregates and cover the surface micro-protrusions, leading to a decrease in the anti-skid performance of the road surface. Based on the above problems, this application proposes a highway bridge asphalt paving device. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a highway bridge asphalt paving device to solve the problems mentioned in the background section.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When the compaction roller compacts the asphalt, the asphalt adhesion detection component detects the asphalt adhesion on the compaction roller. When asphalt adhesion is detected on the surface of the compaction roller, the anti-adhesion agent in the storage box is sprayed onto the surface of the compaction roller by the anti-adhesion agent spraying component. The solvent-based components contained in the anti-adhesion agent can slightly penetrate into the asphalt surface, reducing the viscosity of the asphalt and causing the adhered asphalt to be thrown off by the compaction roller. Moreover, the anti-adhesion agent can form a protective film on the surface of the compaction roller. The film formed by the anti-adhesion agent has a low coefficient of friction, preventing asphalt from adhering to the surface of the compaction roller, thus avoiding excessive asphalt adhesion on the surface of the compaction roller and preventing excessive asphalt adhesion from affecting the compaction of the asphalt.

[0021] Reference Figure 1-4A highway bridge asphalt paving device includes a movable base 1, a fixed seat 2 fixedly mounted at the bottom of the movable base 1, a compaction roller 3 rotatably mounted inside the fixed seat 2, an asphalt adhesion detection component mounted on the right side of the movable base 1, a storage box 12 fixedly mounted on the top of the movable base 1, an anti-sticking agent spraying component mounted on the surface of the movable base 1, a placement box 19 fixedly mounted on the top of the movable base 1, a mixing component mounted on the surface of the placement box 19, a discharge pipe 21 fixedly mounted at the bottom of the placement box 19, a control valve fixedly mounted on the discharge pipe 21, and a movable component mounted on the surface of the movable base 1. The movable component includes a mounting frame 25 and a hand handle 27, the hand handle 27 being fixedly mounted on the surface of the movable base 1, and the mounting frame 25 being fixedly mounted on the bottom of the movable base 1. The mounting frame 25 is fixedly equipped with a movable wheel 26 at its bottom. The hand handle 27 drives the mounting frame 25 to move via the movable base 1, causing the mounting frame 25 to roll on the ground under the movable wheel 26. This allows asphalt to fall to different positions on the ground, and the asphalt is smoothed by the scraper at the bottom of the movable base 1. The movable base 1 drives the compaction roller 3 via the fixed seat 2 to compact the smoothed asphalt. The asphalt adhesion detection component includes a mounting inclined plate 4 fixedly installed on the movable base 1. A movable rod 5 is slidably installed inside the mounting inclined plate 4. A connecting frame 6 is fixedly installed at one end of the movable rod 5, and a circular plate 8 is fixedly installed at the other end of the movable rod 5. A contact roller 7 is rotatably installed inside the connecting frame 6. The contact roller 7 contacts the compaction roller 3, and the circular plate 8 faces the mounting inclined plate 4. A spring 9 is connected between the components. A mounting housing 10 is fixedly installed on the surface of the mounting inclined plate 4. A pressure sensor 11 is fixedly installed inside the mounting housing 10. The anti-sticking agent spraying assembly includes a gear metering pump 13 fixedly installed on the top of the movable base 1. An inlet pipe 14 is fixedly installed at the inlet end of the gear metering pump 13. The inlet end of the inlet pipe 14 passes through the storage box 12 and extends into the interior of the storage box 12. An outlet pipe 15 is fixedly installed at the outlet end of the gear metering pump 13. A diverter pipe 16 is fixedly installed at the outlet end of the outlet pipe 15. A siphon atomizing nozzle 17 is fixedly installed at the outlet end of the diverter pipe 16. There are several siphon atomizing nozzles 17, and the several diverter pipes 16 are arranged in a linear array to spray the anti-sticking agent to different positions of the compaction roller 3, thereby controlling the pressure. Asphalt adhering to different positions on the compaction roller 3 is cleaned. A fixing plate 18 is fixedly installed on the surface of the diversion pipe 16. The fixing plate 18 is fixedly installed at the bottom of the movable base 1. When asphalt adheres to the surface of the compaction roller 3, the adhered asphalt will move with the rotation of the compaction roller 3. The adhered asphalt will push the contact roller 7 to move. The contact roller 7 drives the circular plate 8 to stretch the spring 9 through the connecting frame 6 and the moving rod 5, so that the circular plate 8 applies pressure to the detection end of the pressure sensor 11, indicating that asphalt has adhered to the surface of the compaction roller 3. The gear metering pump 13 draws the anti-sticking agent in the storage box 12 into the outlet pipe 15 through the inlet pipe 14, and enters the siphon atomizing nozzle 17 through the diversion pipe 16, and sprays it onto the surface of the compaction roller 3. The anti-sticking agent contains solvent-based components.This reduces the viscosity of the asphalt, causing the adhering asphalt to be thrown off by the compaction roller 3. Furthermore, the anti-adhesion agent forms a protective film on the surface of the compaction roller 3, preventing asphalt from adhering to its surface and thus avoiding excessive asphalt buildup that could negatively impact asphalt compaction.
[0022] Specifically, the mixing assembly includes a mixing motor 22 fixedly installed on the top of the placement box 19. A mixing shaft 23 is fixedly installed at the output end of the mixing motor 22, and a mixing plate 24 is fixedly installed on the surface of the mixing shaft 23. Both the mixing shaft 23 and the mixing plate 24 are located inside the placement box 19. The asphalt to be laid is added into the placement box 19 through the feed hopper 20, and the mixing motor 22 drives the output end to rotate the mixing shaft 23. The mixing shaft 23 drives the mixing plate 24 to mix the asphalt. The mixed asphalt falls to the ground to be laid through the discharge pipe 21.

A feed hopper 20 is fixedly installed on the top of the placement box 19. The discharge end of the feed hopper 20 passes through the placement box 19 and extends into the interior of the placement box 19. The liquid filling pipe 28 facilitates the replenishment of anti-sticking agent to the storage box 12, and the feed hopper 20 facilitates the addition of asphalt into the interior of the placement box 19.
[0024] The asphalt paving device for highway bridges is connected to 220V mains power, and the main controller can be a conventional known device such as a computer for control.
[0025] In use: When asphalt adheres to the surface of the compaction roller 3, the adhered asphalt will move along with the rotation of the compaction roller 3, causing the adhered asphalt to come into contact with the contact roller 7. The adhered asphalt will push the contact roller 7 to move, and the contact roller 7 will push the moving rod 5 to move through the connecting frame 6. The moving rod 5 will drive the circular plate 8 to stretch the spring 9, so that the circular plate 8 will apply pressure to the detection end of the pressure sensor 11. When the circular plate 8 detects a change in pressure, it indicates that asphalt has adhered to the surface of the compaction roller 3. The gear metering pump 13 will then be started, and the gear metering pump 13 will flow through the inlet pipe 14. The anti-adhesion agent in the storage box 12 is drawn into the outlet pipe 15 and then flows into the diversion pipe 16 for diversion. The diverted anti-adhesion agent enters the siphon atomizing nozzle 17 and is sprayed onto the surface of the compaction roller 3. The anti-adhesion agent contains solvent components that can slightly penetrate into the asphalt surface, reducing the viscosity of the asphalt and causing the attached asphalt to be thrown off by the compaction roller 3. Moreover, the anti-adhesion agent can form a protective film on the surface of the compaction roller 3. The film formed by the anti-adhesion agent has a low coefficient of friction, preventing asphalt from adhering to the surface of the compaction roller 3.
