[0002] With rapid economic development and accelerating urbanization, the scale and speed of road traffic infrastructure construction are constantly increasing. Asphalt pavement, due to its advantages of good smoothness, skid resistance, comfort, and low noise, has been widely used in traffic engineering projects such as highways, urban roads, and airport runways. In recent years, the annual increase in the mileage of asphalt pavement in my country has been increasing, which has placed higher demands on asphalt pavement construction technology and equipment. In order to ensure the construction quality and service life of asphalt pavement, every step of the construction process is crucial. Among them, the compaction process is the key to determining the smoothness and density of asphalt pavement. Traditional manual compaction methods are not only inefficient, but also difficult to guarantee the consistency of compaction quality, and cannot meet the needs of large-scale and high-quality asphalt pavement construction. Therefore, the research and development and application of efficient and reliable compaction devices for asphalt pavement construction has become an inevitable trend in the industry.

[0003] A search revealed Chinese Patent Publication No. CN214423078U, which discloses a leveling device for asphalt pavement construction. The device includes a fixed mounting base, a mounting frame, and a leveling roller. A bidirectional electric telescopic rod is installed at the middle of the upper end of the fixed mounting base. The mounting frame is located at the lower end of the fixed mounting base, and the leveling roller is rotatably connected to the lower end of the mounting frame. An mounting rod is fixedly connected to the upper end of the support rod. A garbage collection box is located at the right end of the cleaning broom, and fixing blocks are fixedly connected to both the front and rear ends of the garbage collection box. A connecting block is located in the middle of the mounting groove. This leveling device for asphalt pavement construction allows for easy adjustment of the leveling roller's height, making it suitable for different road surfaces. It facilitates cleaning of garbage on the outer surface of the leveling roller, keeping it clean and enabling better leveling of the road surface for a better paving effect. It also facilitates the removal of swept garbage. The device is highly practical and very convenient to use. However, it is difficult to reach and conform to corners and irregular areas in complex terrain and narrow spaces, resulting in these areas not being effectively leveled. Utility Model Content

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, a small motor drives the rotation of bevel gear one, which in turn drives the rotation of the steering knuckle to achieve the steering function. This allows the flattening roller to flatten the ground at different locations, ensuring the smoothness of power transmission. This makes the steering operation of the flattening roller more stable and reliable, reducing the time required for equipment to switch between different areas. At the same time, by rotating the compaction plate, the angle of the compaction plate can be fixed, which can better fit the corners and irregular areas of complex terrain, achieving comprehensive flattening treatment.

[0030] 2. In this utility model, heat is generated by the electric heating wire inside the heating tube, and then transferred to the heat-conducting medium for uniform transfer, and then to the flattening roller. This allows heat to be generated during flattening, ensuring that the temperature of the flattening roller is maintained. In this way, the asphalt can maintain good fluidity and plasticity. Under the action of the flattening roller, it is easier to fill the gaps and uneven areas of the road surface, making the road surface denser and smoother, improving the compaction quality, preventing the asphalt from solidifying due to cooling, and thus enhancing the efficiency of compaction operations.

[0043] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 4 The front and rear sides of the support plate 1 are fixedly connected to the pedal 24, the front and rear sides of the cockpit 3 are rotatably connected to the door panel 25, the opposite side of the door panel 25 is fixedly connected to the handle 26, the outer wall of the handle 26 is fixedly connected to the anti-slip sleeve 27, the top front side of the connecting frame 12 is fixedly connected to two lights 21, and the left side of the connecting frame 12 is fixedly connected to two bogies 22.

[0047] Working principle: The device is moved by a dual-head motor 4. The small motor 8 drives the rotation of bevel gear 9, which in turn drives the rotation of bevel gear 10. The rotation of bevel gear 10 drives the rotation of steering knuckle 11, which in turn drives the connecting frame 12 to achieve steering function. This allows the flattening roller 13 to flatten the ground at different locations. Bevel gear transmission has the advantages of high transmission efficiency and stable transmission ratio. During the rotation of steering knuckle 11, it can ensure the smoothness of power transmission and reduce vibration and impact during transmission. This makes the steering operation of flattening roller 13 more stable and reliable, which helps to improve the quality of flattening operation and avoid the problem of uneven road surface flattening caused by unstable steering. It also reduces the time for equipment to switch between different areas, allowing construction workers to flatten the ground at different locations more efficiently and speeding up the construction progress. At the same time, by rotating the compaction plate 16 and engaging the positioning pin 17 with the corresponding hole 15, the angle of the compaction plate 16 is fixed, which can better fit the corners and irregular areas of complex terrain and achieve comprehensive flattening treatment.

[0048] Heat is generated by the electric heating wire 202 inside the heating tube 201, and then transferred to the heat-conducting medium 203 for uniform distribution. It is then transferred to the flattening roller 13, so that heat is generated during flattening, ensuring that the temperature of the flattening roller 13 is maintained. This allows the asphalt to maintain good fluidity and plasticity. Under the action of the flattening roller 13, it is easier to fill the gaps and uneven areas of the road surface, making the road surface denser and smoother, improving the compaction quality, and preventing the asphalt from solidifying due to cooling. This enhances the efficiency of the compaction operation. At the same time, the sealing sleeve 205 and the rubber sealing ring 206 effectively seal the heat inside, reducing heat dissipation from the surface of the equipment and reducing the risk of workers being burned by accidental contact with high-temperature components during operation, thus improving the safety of construction.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
