Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to an asphalt pavement roller for road construction. Background Technology

[0002] Asphalt pavement boasts advantages such as high stability and a long service life under repeated loads, making it an indispensable part of modern road construction. Asphalt concrete requires thorough mixing before paving and compaction, necessitating the use of road rollers. Asphalt pavement rollers are heavy-duty engineering machines specifically designed for compacting asphalt mixtures. They primarily improve the density of the asphalt mixture through vibration compaction, thereby enhancing the overall performance of the pavement. This equipment plays a crucial role in road construction and maintenance.

[0003] The asphalt pavement roller disclosed in publication number CN221877618U, although the utility model has a fixed part, a slot, a connector, a mounting frame, a liquid channel, a fixed frame, a coating sponge roller, a loading box and a nozzle, can control the release agent to flow from the liquid channel to the outer wall of the coating sponge roller through the nozzle, coating the outer wall of the compaction roller. As the compaction roller rotates, the coating is evenly applied, reducing the probability of asphalt sticking to the compaction roller. At the same time, the connector and slot make installation and disassembly convenient. The auxiliary ladder, anti-slip pedal, first handrail and second handrail make it easy for the operator to enter the cab through the auxiliary ladder, and the first handrail and second handrail prevent falls, improving the overall convenience and safety.

[0004] However, when using this utility model, the influence of temperature on asphalt pavement needs to be considered. In summer, when the temperature is high, the temperature of the asphalt mixture is relatively easy to maintain. However, in winter, when the temperature is low, the temperature of the asphalt mixture drops rapidly, and the temperature loss is more significant. At low temperatures, the viscosity of asphalt increases, and the required compaction work also increases accordingly. This may lead to insufficient compaction or pavement quality problems due to excessively low temperatures. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, to solve the above-mentioned technical problems, this utility model provides the following technical solution: an asphalt pavement roller for road construction, which includes:

[0007] The main unit includes a vehicle body, on which a climbing frame is fixedly connected;

[0008] A road rolling assembly includes a mounting frame on which a rolling roller and a heating roller are rotatably connected. An electric heating wire is installed inside the heating roller, and an applicator roller is provided above both the rolling roller and the heating roller.

[0009] A coating assembly includes a gearbox, on which a servo motor is mounted. The output end of the servo motor is connected to a first rotating rod. A driving sprocket and a first gear are rotatably connected to the surface of the first rotating rod.

[0030] Example 1

[0031] Reference Figure 1 -5, the first embodiment of this utility model, provides an asphalt pavement roller for road construction, the structure of which includes:

[0032] The main unit 100 includes a vehicle body 101, on which a climbing frame 102 is fixedly connected. Workers can easily enter the vehicle body 101 through the climbing frame 102 to operate the vehicle body 101 and the paint assembly 300.

[0033] The road roller assembly 200 includes a mounting frame 201, on which a compaction wheel 202 and a heating wheel 203 are rotatably connected. An electric heating wire 204 is installed inside the heating wheel 203. An applicator roller 205 is positioned above both the compaction wheel 202 and the heating wheel 203. During use, as the vehicle body 101 moves forward, the electric heating wire 204 in the heating wheel 203 heats the surface, raising its temperature. The asphalt pavement first passes over the heating wheel 203, which heats it before the compaction wheel 202 compacts it. The height of the heating wheel 203 is slightly higher than the compaction wheel to prevent the asphalt pavement from being directly compacted by the heating wheel 203, thus preventing asphalt aging due to excessive temperature. Since both the heating wheel 203 and the compaction wheel 202 are coated with a release agent by the applicator roller 205, sticking to the wheels is effectively prevented.

[0034] The coating assembly 300 includes a gearbox 301, on which a servo motor 302 is mounted. The output end of the servo motor 302 is connected to a first rotating rod 303. A drive sprocket 304 and a first gear 305 are rotatably connected to the surface of the first rotating rod 303. A chain 306 meshes with the surface of the drive sprocket 304, and a driven sprocket 307 meshes with the chain 306. A second rotating rod 308 is positioned at the center of the driven sprocket 307. Eccentric blocks 309 are fixed to both ends of the second rotating rod 308. A control rod 310 is rotatably connected to the eccentric blocks 309, and a stop block 311 is rotatably connected to one end of the control rod 310. A second gear 312 meshes with the surface of the first gear 305. During use, starting the servo motor 302 causes the first rotating rod 303 to rotate, simultaneously driving the drive sprocket 304 and the first gear. When gear 305 rotates, the first gear 305 drives the meshing second gear 312 to rotate. The first gear 305 and the second gear 312 separate to form a low pressure, which draws the release agent from the suction pipe 3011 and pushes it to the other side through the inner wall of the gearbox 301. The two gears, the first gear 305 and the second gear 312, mesh together to form a high pressure, which discharges the release agent from the delivery pipe 3012 into the distribution pipe 2014. The driving sprocket 304 drives the driven sprocket 307 to rotate under the transmission action of the chain 306, which in turn drives the second rotating rod 308 to rotate, which further drives the eccentric block 309 to rotate, thereby driving the control rod 310 to move, causing the stop block 311 to move up and down. When the left stop block 311 moves up, the right stop block 311 moves down, and the release agent is discharged from the left side of the distribution pipe 2014. Conversely, the release agent is discharged from the right side of the distribution pipe 2014.

[0035] Furthermore, a liquid storage tank 2011 is installed on the mounting frame 201, and a discharge port 2012 is provided on the liquid storage tank 2011. The liquid storage tank 2011 contains a release agent, which can be replenished through the discharge port 2012 when the release agent is used up.

[0036] Furthermore, a rectangular groove is provided on the top of the mounting frame 201. A guide pipe 2013 is installed on the inner bottom wall of the rectangular groove. The release agent in the rectangular groove can be guided to the coating roller 205 through several guide pipes 2013, and then evenly coated onto the surface of the heating roller 203 and the rolling roller 202.

[0037] Furthermore, a through groove is provided between the rectangular grooves, and a liquid distribution pipe 2014 is fixed in the through groove. The liquid distribution pipe 2014 evenly separates the separating agent into the rectangular grooves on both sides.

[0038] Furthermore, a fixing bracket 2015 is installed on the separating tube 2014, and the second rotating rod 308 is installed on the fixing bracket 2015. The fixing bracket 2015 provides an installation position for the second rotating rod 308, which facilitates the control of the movement of the stop block 311.

[0039] Furthermore, a liquid extraction pipe 3011 is fixed on one side of the gearbox 301, and a delivery pipe 3012 is fixed on the other side of the gearbox 301. The release agent in the storage tank 2011 is extracted through the liquid extraction pipe 3011 and delivered to the distribution pipe 2014 through the delivery pipe 3012.

[0040] During use, the staff can first easily enter the vehicle body 101 through the climbing frame 102 to operate the vehicle body 101 and the paint assembly 300. The servo motor 302 is started to make the first rotating rod 303 rotate. The first rotating rod 303 simultaneously drives the drive sprocket 304 and the first gear 305 to rotate. The first gear 305 drives the meshing second gear 312 to rotate. The first gear 305 and the second gear 312 separate to form a low pressure, which draws the release agent from the liquid extraction pipe 3011 and pushes it to the other side through the inner wall of the gearbox 301. The two gears, the first gear 305 and the second gear 312, mesh together to form a high pressure, which discharges the release agent from the delivery pipe 3012 into the liquid distribution pipe 2014.

[0041] Then, the drive sprocket 304 drives the driven sprocket 307 to rotate under the transmission action of the chain 306, which in turn drives the second rotating rod 308 to rotate, further driving the eccentric block 309 to rotate, thereby driving the control rod 310 to move, causing the stop block 311 to move up and down. When the left stop block 311 moves up, the right stop block 311 moves down, and the release agent is discharged from the left side of the liquid distribution pipe 2014. Conversely, the release agent is discharged from the right side of the liquid distribution pipe 2014. The release agent discharged from the left side is applied to the heating wheel 203, and the release agent discharged from the right side is applied to the rolling wheel 202.

[0042] Finally, as the vehicle body 101 moves forward, the heating wire 204 inside the heating wheel 203 heats the road surface, raising its temperature. The asphalt road surface that the heating wheel 203 passes over is heated by the heating wheel 203, and then the road surface is compacted by the compaction wheel 202. The height of the heating wheel 203 is slightly higher than that of the compaction wheel to prevent the asphalt road surface from being directly compacted by the heating wheel 203, thus preventing the asphalt from aging due to excessive temperature. Since both the heating wheel 203 and the compaction wheel 202 are coated with a release agent by the coating roller 205, the sticking phenomenon can be effectively prevented.

[0043] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
