Description

Technical Field

[0001] This utility model belongs to the field of road construction technology, specifically relating to a tool for SBS modified asphalt concrete road construction. Background Technology

[0002] SBS modified asphalt is made by adding a certain proportion of SBS modifier to base asphalt. Through shearing and mixing, SBS is evenly dispersed in the asphalt. Simultaneously, a certain proportion of a specific stabilizer is added to form an SBS blend. The excellent physical properties of SBS are used to modify the asphalt. Modified asphalt is an asphalt binder made by adding external admixtures (modifiers) such as rubber, resin, polymers, finely ground rubber powder, or other fillers, or by taking measures such as slight oxidation processing of the asphalt, to improve the performance of the asphalt or asphalt mixture. Currently, modified road asphalt is mainly used for paving applications in special occasions such as airport runways, waterproof bridge decks, parking lots, sports fields, heavy traffic roads, intersections, and road curves. Recently, Europe has applied modified asphalt to the maintenance and reinforcement of highway networks, significantly promoting the widespread application of modified road asphalt. After asphalt roads are laid, they need to be rolled, which requires the use of rolling devices. Existing rolling devices can basically meet the construction needs, but there are still some shortcomings. On the one hand, when using existing rolling devices, asphalt is highly viscous, so asphalt easily adheres to the rollers of the rolling device, affecting the rolling quality. On the other hand, when asphalt adheres to the rollers, it is inconvenient to remove it from the existing rolling devices. Utility Model Content

[0014] 1. This utility model is simple and quick to operate. By setting up a rolling mechanism, it is easy to compact and level the SBS modified asphalt concrete pavement. By setting up a cleaning mechanism, it is easy to clean the concrete adhering to the roller during rolling, so that the outer surface of the roller is restored to flatness.

[0023] like Figure 1 , Figure 2 and Figure 3As shown, this utility model includes a tie rod 1 and a rolling mechanism for compacting SBS modified asphalt concrete. A Y-shaped rod 4 is provided at the lower end of the tie rod 1, and a handle 2 is provided at the upper end of the tie rod 1. One end of the Y-shaped rod 4 is connected to the lower end of the tie rod 1 through a universal joint cross shaft 3, and the other two ends of the Y-shaped rod 4 are fixedly connected to the rolling mechanism.

[0024] The rolling mechanism includes two baffles 5, a roller 9 disposed between the two baffles 5, and a cleaning mechanism. A first fixing rod 6 and a second fixing rod 7 are disposed between the two baffles 5. The first fixing rod 6 and the second fixing rod 7 are respectively located on both sides of the roller 9. The first fixing rod 6 is fixedly connected to the other two ends of the Y-shaped rod 4.

[0025] The cleaning mechanism includes a first scraper 10 and a second scraper 12 disposed between the two baffles 5. The cross-sections of the first scraper 10 and the second scraper 12 are both conical. The tips of the first scraper 10 and the second scraper 12 abut against the outer surface of the roller 9. A first connecting rod 11 is inserted through the end of the first scraper 10 away from the tip of the tip, and a second connecting rod 13 is inserted through the end of the second scraper 12 away from the tip of the tip. The two ends of the first connecting rod 11 and the second connecting rod 13 are respectively inserted on the two baffles 5.

[0026] In practical use, the rolling mechanism facilitates the compaction and leveling of SBS modified asphalt concrete pavement. The cleaning mechanism facilitates the removal of concrete adhering to the roller 9 during rolling, restoring the outer surface of the roller 9 to a smooth surface. Furthermore, the first scraper 10 and the second scraper 12 facilitate repeated scraping of concrete from both sides. This not only improves the cleaning efficiency without affecting the operation of the roller 9, but also guides the scraped concrete to the ground for secondary compaction, avoiding waste of SBS modified asphalt concrete. This facilitates faster and better completion of concrete pavement compaction and ensures the quality of the SBS modified asphalt concrete pavement.

[0027] It should be noted that by setting a flexible universal joint cross shaft 3, the direction of the roller 9 can be adjusted while rolling and compacting. This not only adapts to the compaction requirements of curved road surfaces, but also ensures that the movement directions of the tie rod 1 and the roller 9 are not on the same plane. This allows construction workers to drive the roller 9 through the tie rod 1 even when standing on the side, making it highly flexible.

[0028] It should be noted that the lower end of the baffle 5 is higher than the curb, so that when the side of the roller 9 is in close contact with the curb, the baffle 5 can be located above the curb, thus preventing the junction between the road surface and the curb from being uncompacted.

[0029] In this embodiment, a roller 8 is inserted inside the roller 9, and the two ends of the roller 8 are respectively fixed to the middle of the two baffles 5.

[0030] In actual use, nuts are installed at both ends of the roller 8. The nuts are located on the outside of the baffle 5, which makes it easy to fix the roller 8 and does not restrict the roller 9 from rotating around the roller 8, thereby achieving rolling compaction on the SBS modified asphalt concrete pavement.

[0031] In this embodiment, the first scraper 10 is located between the second fixed rod 7 and the roller 9, and the cone tip of the first scraper 10 is inclined downward and lower than the first connecting rod 11; the second scraper 12 is located between the first fixed rod 6 and the roller 9, and the cone tip of the second scraper 12 is inclined upward and higher than the second connecting rod 13.

[0032] In actual use, construction workers pull the roller 9 backward using the lever 1, as shown. Figure 1 In the process, roller 9 rotates counterclockwise, the first scraper 10 performs the first cleaning operation, and the second scraper 12 performs the second cleaning operation, thus achieving double-sided repeated scraping of concrete. This effectively avoids the problem of unevenness caused by excessive concrete adhering to the surface of roller 9 after a period of use, and improves the cleaning effect.

[0033] In this embodiment, both the first connecting rod 11 and the second connecting rod 13 are triangular prisms, and the ends of both the first connecting rod 11 and the second connecting rod 13 extend out of the baffle 5 and are fitted with limiting members 15.

[0034] In this embodiment, the limiting member 15 is an L-shaped member, one end of the limiting member 15 is provided with a first through hole adapted to the triangular prism, and the other end of the limiting member 15 is connected to the baffle 5 through a hinge.

[0035] In actual use, both ends of the first connecting rod 11 and the second connecting rod 13 pass through the baffle 5, extend into the limiting member 15, and do not extend out of the limiting member 15, thereby limiting the first connecting rod 11 and the second connecting rod 13 and preventing them from rotating. By rotating the limiting member 15 outward with the hinge as the axis, the limitation on the first connecting rod 11 and the second connecting rod 13 can be released, and the first connecting rod 11 and the second connecting rod 13 can be pulled out from the first scraper 10, the second scraper 12 and the baffle 5. The first scraper 10 and the second scraper 12 can then be removed for cleaning or replacement.

[0036] In this embodiment, both the first scraper 10 and the second scraper 12 are provided with a second through hole adapted to the triangular prism.

[0037] In actual use, by setting both the first connecting rod 11 and the second connecting rod 13 to be triangular prisms, the stability of the connection between the first scraper 10 and the first connecting rod 11, as well as the stability of the connection between the second scraper 12 and the second connecting rod 13, is improved, thereby increasing the support force on the first scraper 10 and the second scraper 12 and ensuring the cleaning effect.

[0038] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
