[0002] In road construction, the transition slope at the junction of the cement road in front of residents' houses and the asphalt main road often relies on manual experience and traditional compaction equipment. In the traditional method, asphalt needs to be spread manually and compacted with compaction equipment. However, due to the lack of limiting and guiding structure, it is difficult for people to control the movement of the compaction equipment on the asphalt slope, which makes the slope inclination easily affected by human factors and causes unevenness. Summary of the Invention
[0003] To overcome the drawbacks of manual control over the movement of compaction equipment on asphalt slopes, which makes the slope inclination susceptible to human factors and results in unevenness, this invention provides an asphalt overlay device for road reconstruction.
[0004] Technical Solution: An asphalt overlay device for road reconstruction includes an installation frame; it also includes a connecting plate, cylinder one, a limit rod, cylinder two, a limit plate, cylinder three, a connecting rod, mounting rod one, and a compactor; two symmetrically arranged connecting plates are connected to the installation frame; cylinder one is fixedly connected to each connecting plate; a limit rod is rotatably connected to the telescopic end of each cylinder one; cylinder two is fixedly connected to each connecting plate; several limit plates are fixedly connected to the telescopic end of each cylinder two through the installation plate; each limit rod has a through groove to avoid the limit plates; cylinder three is fixedly connected to each limit rod; a connecting rod is fixedly connected to the telescopic end of each cylinder three; each connecting rod is slidably connected to the corresponding limit rod; several mounting rods one are connected together by the two connecting rods; and the compactor is slidably connected to all the mounting rods one.
[0005] Optionally, the limiting plate consists of a contraction portion and a receiving portion.
[0006] Optionally, each limiting plate has a heating wire inside its receiving portion.
[0007] Optionally, the compactor is equipped with several locking devices for securing the compactor to the mounting rod.
[0008] Optionally, the compactor is equipped with a grip bar.
[0009] Optionally, the contact area between the compactor and the asphalt is coated with an anti-stick coating.
[0010] Optionally, the connecting plate is configured as an electrically telescopic plate; the mounting rod is composed of several support rods spliced together.
[0011] Optionally, it also includes a grooving roller; the mounting rod is detachably connected to the connecting rod; the grooving roller is detachably connected between the two connecting rods, and a number of protrusions are fixedly connected at equal intervals on the outer ring surface of the grooving roller.

[0013] Optionally, the groove roller is made of a material with high thermal conductivity.
[0014] The beneficial effects of this invention are as follows: 1. This invention quickly assembles the laying frame by lowering the limiting plate, and then uses the track of the limiting rod to guide the compactor to compact the slope, ensuring the compaction effect and significantly improving construction efficiency and quality; by moving the tractor left and right to move the equipment, the inclination of the limiting rod can be adjusted. Since the compactor slides within the track of the limiting rod, the inclination of the compacted slope is the same as the inclination of the limiting rod; thus, by adjusting the inclination of the limiting rod, the inclination of the slope can be flexibly controlled to meet various user needs.

Detailed Implementation
[0025] The embodiments of the present invention will be described below with reference to the accompanying drawings. Example
[0026] An asphalt overlay device for road reconstruction, such as Figures 1-5 As shown, it includes a mounting bracket 1;
[0027] It also includes a connecting plate 2, cylinder 1 3, a limiting rod 4, cylinder 2 5, a limiting plate 6, cylinder 3 7, a connecting rod 8, a mounting rod 1 9, and a compactor 11; two connecting plates 2 are connected to the mounting frame 1 in a symmetrical arrangement; a cylinder 1 3 is fixedly connected to each connecting plate 2; a limiting rod 4 is rotatably connected to the telescopic end of each cylinder 1 3; a cylinder 2 5 is fixedly connected to each connecting plate 2; several limiting plates 6 are fixedly connected to the telescopic end of each cylinder 2 5 through the mounting plate; each limiting rod 4 has a through groove 401 to avoid the limiting plates 6; a cylinder 3 7 is bolted to each limiting rod 4; a connecting rod 8 is fixedly connected to the telescopic end of each cylinder 3 7; each connecting rod 8 is slidably connected to the corresponding limiting rod 4; two connecting rods 8 are connected to two mounting rods 1 9; all mounting rods 1 9 are slidably connected to the compactor 11.
[0028] The limiting plate 6 consists of a contraction part 601 and a receiving part 602.
[0029] Each limiting plate 6 has a heating wire installed in its receiving portion 602.
[0030] To prevent the compactor 11 from moving left and right on the mounting rod 9 during operation, two locking devices 10 are installed on the compactor 11.
[0031] To facilitate the movement of the compactor 11, a grip bar is provided on the compactor 11.
[0032] To prevent asphalt from adhering, the contact area between the compactor 11 and the asphalt is coated with an anti-stick coating (such as polytetrafluoroethylene).
[0033] by Figure 1 Based on the viewing angle, the side where mounting bracket number 1 is located is the left side, and the side where connecting rod number 8 is located is the right side.
[0034] In use, firstly, the mounting frame 1 is fixed to the tractor, and the invention is moved to the junction of the cement road and the asphalt main road in front of the gate using the tractor. Then, the two cylinders 3 are controlled to drive the corresponding limiting rods 4 and their associated components to descend, so that the limiting rods 4 are firmly abutted against the asphalt main road and the cement road surface. Next, the cylinder 5 is controlled to drive the limiting plate 6 to descend, so that the limiting plate 6 is tightly pressed against the cement road surface, thus forming an asphalt interception plate together with all the limiting plates 6 at the front and rear. Figure 1 and Figure 2 As shown.
[0035] Asphalt is manually pre-laid between the asphalt interception plates composed of all the limiting plates 6, forming an inclined slope. Then, the control cylinder 3 7 drives the connecting rod 8, the mounting rod 1 9, and the compactor 11 to move back and forth within the track of the limiting rod 4. During movement, the compactor 11 is started to compact the asphalt slope. During compaction, the locking device 10 fixes the compactor 11 to the mounting rod 1 9 to prevent the compactor 11 from moving left and right on the mounting rod 1 9 during operation, which would affect the compaction effect. After compaction of one section, the... Unlock the locking device 10 to release the fixation between the compactor 11 and the mounting rod 9. Manually pull the compactor 11 to slide it on the mounting rod 9, allowing it to move to the uncompacted area. Then, use the locking device 10 to fix the compactor 11 back onto the mounting rod 9. Next, control the cylinder 3 7 to drive the connecting rod 8, the mounting rod 9, and the compactor 11 to reciprocate within the track of the limit rod 4. During movement, start the compactor 11 to compact the asphalt slope. Repeat the above actions to compact the asphalt slope. All areas are compacted. The telescopic end of cylinder 3 is rotatably connected to the limiting rod 4. Controlling the two cylinders 3 to drive the corresponding limiting rod 4 and its associated components downwards to press against the asphalt main road and cement pavement, the tilt of the limiting rod 4 can be adjusted by moving the tractor left and right. Since the compactor 11 slides within the track of the limiting rod 4, the tilt of the compacted slope is the same as the tilt of the limiting rod 4. Thus, by adjusting the tilt of the limiting rod 4, the slope tilt can be flexibly controlled to meet various user needs. After compaction, controlling the two cylinders 3 to drive the corresponding limiting rod 4 and its associated components upwards to reset, while simultaneously controlling cylinder 5 to drive the limiting plate 6 upwards, separating and resetting the limiting plate 6 from the side of the asphalt slope, completing the asphalt slope overlay. In this way, the present invention quickly forms a paving frame by lowering the limiting plate 6, and then uses the track of the limiting rod 4 to guide the compactor 11 to compact the slope, ensuring the compaction effect and significantly improving construction efficiency and quality.
[0036] When the cement road in front of the gate is uneven, after the control cylinder 25 drives the limit plate 6 to descend, gaps will appear between some limit plates 6 and the cement road, causing asphalt to overflow and protrude from the asphalt slope, forming a skirt. This requires subsequent manual cleaning, which is labor-intensive. Therefore, the limit plate 6 is designed as a telescopic plate, and each limit plate 6 can extend and retract independently. After the control cylinder 25 drives the limit plate 6 to descend, each limit plate 6 can contact the cement road surface, thus reducing gaps, reducing the amount of asphalt outflow, and reducing the amount of labor required for subsequent manual cleaning.
[0037] Considering the lengthy compaction process, the high-temperature asphalt gradually cools during compaction. The cooled asphalt bonds with the limiting plate 6, and forcibly removing it could cause tearing at the slope edge, resulting in rough edges or gaps, affecting the quality of the asphalt slope paving. Therefore, a heating wire is installed on the limiting plate 6. Before the control cylinder 2 5 drives the limiting plate 6 upwards, the heating wire is activated to heat the limiting plate 6, raising the temperature at the contact point between the limiting plate 6 and the asphalt, softening the asphalt, and reducing the bond strength between the asphalt and the limiting plate 6. Then, the control cylinder 2 5 drives the limiting plate 6 upwards, slowly separating the limiting plate 6 from the softened asphalt slope side, avoiding forced removal that could cause tearing at the slope edge and the formation of rough edges or gaps. Example
[0038] Based on Example 1, such as Figures 1-5 As shown, the connecting plate 2 is set as an electric telescopic plate; the mounting rod 9 is composed of several support rods spliced together.
[0039] Before laying, the user can adjust the distance between the two limiting rods 4 and the width of the asphalt interception plate composed of all the limiting plates 6 by controlling the movement of the telescopic ends of the two connecting plates 2. This allows the invention to be adapted to the width of the slope to meet various user needs. Before adjusting the distance between the two limiting rods 4, the installation rod 9 is first removed from the connecting rod 8. The installation rod 9 is composed of several support rods. After the distance between the two limiting rods 4 is adjusted, the support rods are removed or added according to the length between the two limiting rods 4 so that the length of the installation rod 9 is the same as the distance between the limiting rods 4. Then the installation rod 9 is installed back into the connecting rod 8. This allows the compactor 11 to compact the asphalt slope without dead angles. Example
[0040] Based on Example 2, such as Figures 6-7 As shown, it also includes a grooving roller 21; the mounting rod 9 is detachably connected to the connecting rod 8; the grooving roller 21 is detachably connected between the two connecting rods 8, and several protrusions are welded at equal intervals on the outer ring surface of the grooving roller 21.
[0041] It also includes a connecting frame 22 and a mounting rod 23; each cylinder 25 has a connecting frame 22 fixedly connected to its telescopic end; each connecting frame 22 is damped and rotatably connected to a mounting rod 23; the limiting plate 6 is fixedly connected to the corresponding mounting rod 23.
[0042] To facilitate heat absorption by the grooving roller 21, the grooving roller 21 is made of a material with high thermal conductivity (such as tungsten copper alloy).
[0043] After prolonged use, cracks may appear on the surface of asphalt slopes, which typically require partial removal and repair. During repair, an infrared heating plate is first used to heat the slope surface. Then, the asphalt slope surface is removed, and finally, asphalt is laid on top of the old asphalt. To ensure a strong bond between the old and new asphalt, before adding the new asphalt, the installation rod 9 must be detached from the connecting rod 8. Then, the grooving roller 21 is installed on the two connecting rods 8, at which point the protruding plate on the grooving roller 21 partially embeds into the old asphalt. Next, the control cylinder 7 drives the connecting rod 8 and the grooving roller 21 to move back and forth within the track of the limiting rod 4. The grooving roller 21 rolls back and forth on the old asphalt, creating grooves. New asphalt is then laid, forming an "anchoring structure" through the grooves, increasing the contact area between the old and new layers, and then the new asphalt is laid, thus ensuring a strong bond between the old and new asphalt.
[0044] It should be noted that before controlling the grooving roller 21 to reciprocate on the old asphalt, the cylinder 25 can be controlled to move the connecting frame 22, the mounting rod 23, and the limiting plate 6 upwards, so that the limiting plate 6 separates from the limiting rod 4. Then, the mounting rod 23 is manually rotated so that the limiting plate 6 is directly above the grooving roller 21. Then, the cylinder 25 is controlled to move the connecting frame 22, the mounting rod 23, and the limiting plate 6 downwards, so that the limiting plate 6 is close to the grooving roller 21. Figure 7 As shown, the heating wire inside the limiting plate 6 is then controlled to work, and the limiting plate 6 heats up. The heat is radiated to the pressing roller 21 below, thereby heating the pressing roller 21, reducing the adhesion between the pressing roller 21 and the old asphalt, preventing the old asphalt from sticking, and allowing the pressing roller 21 to smoothly press grooves into the old asphalt.
[0045] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
