Description

Technical Field

[0001] This invention relates to the field of asphalt pavement repair equipment technology, and in particular to an efficient asphalt pavement repair paving device and its usage method. Background Technology

[0002] Over time, asphalt pavements develop various defects such as ruts, shoving, and cracks. Repairing these defects typically involves using asphalt pavement repair tape. To ensure better adhesion, a milling machine is used to smooth or roughen the surface. After cleaning away dust, a spray gun is used to manually heat both the asphalt pavement and the repair tape, facilitating better adhesion. Finally, manual compaction is performed. Current asphalt pavement repair tape application methods are not fully automated and still require significant manpower.

[0003] Therefore, this application designs an efficient asphalt pavement repair paving device and its usage method to solve the above problems. Summary of the Invention

The milling device is used to treat the damaged road surface. The first compaction device is used to initially compact the asphalt pavement repair patch. The fixed dragging device is used to drag one side of the asphalt pavement repair patch and fix this side to one side of the damaged road surface. The cut asphalt pavement repair patch is placed on the support plate, and a heating device is provided on the support plate. The heating device heats the asphalt pavement repair patch and the damaged road surface at the same time. The second compaction device is used to finally compact the asphalt pavement repair patch.

[0006] Furthermore, to better realize the present invention, a blower is provided on the trailer frame near the milling device. The blower works to clean the road surface when the milling device processes the road surface. A horizontal tail plate is fixed at the rear end of the trailer frame. A gas cylinder is provided above the tail plate. A bearing plate is hinged to the front side of the tail plate. A second compaction device is fixed to the bottom of the tail plate. The bottom of the bearing plate and the tail plate are respectively hinged to the two ends of the same hydraulic rod. The front end of the bearing plate is tilted downward by extending and retracting the hydraulic rod.

[0007] Furthermore, to better realize the present invention, the milling device includes a milling device telescopic rod fixedly connected to the trailer frame. A bracket is fixed to the top of the milling device telescopic rod, and a mounting beam is fixed to the center of the bracket. A rotatable milling cutter shaft is fixedly connected to the bottom of the mounting beam. A drive motor is connected to one side of the milling cutter shaft through a coupling. Milling cutters are arranged on the milling cutter shaft. The milling cutters are brought into contact with the road surface for milling by raising and lowering the milling device telescopic rod.

[0008] Furthermore, in order to better realize the present invention, the first compaction device includes a compaction device bracket of a gantry structure fixed on the trailer frame. A first compaction device lifting rod is fixed at the bottom center of the compaction device bracket. A first compaction roller is connected to the bottom of the first compaction device lifting rod. The first compaction roller is close to the front end of the bearing plate when the first compaction device lifting rod is lowered to the lowest position and the bearing plate is tilted to the lowest position.

[0009] Furthermore, to better realize the present invention, the fixed towing device includes a fixed towing device bracket with a gantry structure fixed on the trailer frame. Two sets of telescopic devices are installed at the bottom of the fixed towing device bracket. The two sets of telescopic devices are located on both sides of the lifting rod of the first compaction device. The telescopic device includes a first lifting rod of the fixed towing device vertically connected to the bottom of the fixed towing device bracket. A second telescopic rod of the fixed towing device is horizontally connected forward to the bottom of the first lifting rod of the fixed towing device. A third lifting rod of the fixed towing device is vertically connected to the bottom of the front end of the second telescopic rod of the fixed towing device. An electric gripper is installed at the rear end of the bottom of the third lifting rod of the fixed towing device.

[0010] Furthermore, to better realize the present invention, two parallel convex ridges are provided above the bearing plate, and the distance between the two convex ridges is equal to the working width of the milling cutter on the milling device. Several gas channels in two layers are opened in the bearing plate, and the gas channels are connected to the gas tank. A nozzle is installed at the opening of the gas channel at the front end of the bearing plate. The nozzle located in the upper layer is a heating repair patch nozzle, and the nozzle located in the lower layer is a road surface heating nozzle. The opening of the heating repair patch nozzle is parallel to the bearing plate, and the opening of the road surface heating nozzle is inclined downward.

[0011] Furthermore, in order to better realize the present invention, the second compaction device includes a second compaction device lifting rod fixedly connected below the tail plate, the bottom of the second compaction device lifting rod is connected to a second compaction roller, and the length of the second compaction roller is greater than the width between the two protrusions on the bearing plate.

[0012] A method for using an efficient asphalt pavement repair patch paving device includes the following steps: S1. Secure the trailer frame to the rear of the tractor and drive it over the damaged road surface. Lower the telescopic rod of the milling device so that the rotating milling cutter contacts the road surface. Mill a rectangular repair surface by moving the tractor forward and backward. During this process, the blower works continuously to blow away excess debris and dust. S2, the telescopic rod of the milling device is raised to the top, so that the milling cutter shaft rises above the trailer frame, at which point the electric gripper clamps the asphalt pavement repair patch; S3, the hydraulic rod continues to retract, causing the front end of the bearing plate to slowly tilt downwards. During the tilting process, the first lifting rod of the fixed dragging device, the second telescopic rod of the fixed dragging device, and the third lifting rod of the fixed dragging device continue to extend until the electric gripper grabs the asphalt pavement repair patch and presses it against the front end of the damaged pavement repair surface. Then the lifting rod of the first compaction device descends, causing the first compaction roller to press the front part of the asphalt pavement repair patch firmly onto the ground, and bringing the bottom of the asphalt pavement repair patch close to the heating repair patch nozzle at the front end of the bearing plate. S4, the tractor reverses at a constant speed. During the reversal, the second telescopic rod of the fixed towing device extends forward at the same speed, so that the electric gripper clamps the asphalt pavement repair patch and keeps the position against the ground unchanged. During the forward movement, the asphalt pavement repair patch will slowly move from the support plate to the ground. During this process, the heating repair patch nozzle sprays fire to heat the bottom of the asphalt pavement repair patch, and the road surface heating nozzle sprays fire to heat the damaged road surface repair surface. S5. After the asphalt pavement repair patch is fully attached to the repair surface, the electric gripper releases its grip, and the second telescopic rod of the fixed dragging device moves forward a distance of one unit of electric gripper length, so that the electric gripper is disengaged from the bottom of the asphalt pavement repair patch. Then the first lifting rod and the third lifting rod of the fixed dragging device retract and reset, and the hydraulic rod also extends, so that the bearing plate is raised to a horizontal position. S6, the lifting rod of the second compaction device extends, so that the second compaction roller comes into contact with the road surface, and then the tractor moves forward, so that the second compaction roller compacts the part of the asphalt pavement repair patch that has been separated from the electric gripper.

[0013] The beneficial effects of this invention are: The device of this invention can be used for automated and mechanized asphalt pavement repair and paving, eliminating the need for extensive manual labor and greatly improving work efficiency. Attached Figure Description
