A road engineering pavement repairing device

Abstract

This invention discloses a road surface repair device for road engineering, including a movable structure with a fixed ring fixedly installed on it. The distance between the first and second cutting wheels remains fixed, thereby cutting the road surface into two straight lines. The asphalt road surface is heated and softened by a heating structure, and the asphalt located between the two straight lines is shoveled up by a cleaning device, thus realizing the cutting and cleaning of the road surface. This reduces the demand on equipment, does not cause damage to the operator's arms, has low noise, and is easier to operate. After the first asphalt road surface is shoveled, the device can be adjusted to switch to a single cutting wheel for cutting, while the other cutting wheel acts as a limiter, so that the distance of each shoveling of asphalt is kept approximately the same. Alternating use reduces wear on the cutting wheels, making the equipment have a longer service life than traditional devices.

Description

Technical Field

[0001] This invention relates to the field of road engineering, and more specifically to a road surface repair device for road engineering. Background Technology

[0002] Roads arose alongside human activities and, in turn, promoted social progress and development; they are a symbol of historical civilization and a sign of scientific advancement.

[0003] In road engineering, road surface maintenance is very important. When problems such as damage or depressions occur on the road surface, they need to be repaired in a timely manner to facilitate the normal and stable operation of traffic.

[0004] However, the road repair process requires a lot of equipment, but it can be roughly divided into several parts. First, the road surface is cut with a cutting device. After the cutting is completed, the asphalt in the cut area is chipped away little by little with an electric pick. Then the debris is cleaned up. Finally, new asphalt is used to fill and compact the cut area, thus completing the entire repair process.

[0005] However, during the work, it was found that using an electric pick to continuously strike the ground was not only physically demanding and noisy, but the vibration of the electric pick also caused considerable damage to the operator's arms. In addition, it required a lot of equipment, which increased the cost of road repair. Summary of the Invention

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0028] like Figures 1 to 9As shown, a road surface repair device for road engineering includes a movable structure 1, on which a fixed ring 2 is fixedly installed. A groove 9 is provided at the top of the fixed ring 2, and a slider 10 is slidably connected within the groove 9. A rotating ring 3 is fixedly connected to the top of the slider 10, and a cutting structure 5 is installed within the rotating ring 3. A lifting structure 7 is installed on the cutting structure 5, and an adjusting plate 6 is fixedly installed at the top of the lifting structure 7. A limit ring 12 is fixedly sleeved on the outer wall of the adjusting plate 6. An adjusting structure 19, a heating structure 37, and a cleaning structure 22 are installed within the cutting structure 5. The entire structure is moved using the movable structure 1. During the movement, the cutting structure 5 is activated to cut the road surface. The lifting structure 7 ensures that the cutting structure 5 can complete the cutting smoothly. At the same time, the heating structure 37 softens the asphalt road surface. Finally, the cleaning structure 22 cleans the cut asphalt road surface, thus completing the overall cutting and repair work. An adjusting plate 6 is also provided, which can adjust the rotation direction of the cutting structure 5 to better complete the cutting work and reduce limitations. Meanwhile, the fixed ring 2 and the rotating ring 3 assist in the rotation to ensure the normal operation of the rotation work.

[0029] The movable structure 1 is generally inverted U-shaped. Guide rail grooves are provided at both bottom ends of the movable structure 1, with a guide rail slidably connected in each groove. The two guide rails are arranged parallel to each other. A through groove is provided on the movable structure 1, and a limit groove 11 is provided on the inner wall of the through groove. An adjusting disc 6 extends into the through groove and is rotatably connected to it. A limit ring 12 extends into the limit groove 11 and is rotatably connected to it. During operation, the two guide rails are arranged parallel, allowing the movable structure 1 to move linearly along the two parallel guide rails, thereby cutting the road surface in a straight line. After cutting the first line, rotating the adjusting disc 6 causes the cutting structure to rotate 180 degrees, allowing it to return smoothly and cut the second line. Furthermore, the movable structure 1 can be driven by a lead screw, and the adjusting disc 6 can be replaced with a servo motor signal control, thus achieving automated cutting and more efficient completion of the cutting and repair work.

[0030] The lifting structure 7 includes an electric telescopic rod, the top of which is fixedly connected to the bottom of the adjusting plate 6, and the output end of which is fixedly connected to the top of the cutting structure 5. Guide blocks 8 are fixedly connected to both sides of the cutting structure 5. Connecting rods 4 are symmetrically fixedly connected to the inner wall of the rotating ring 3. One end of the connecting rod 4 is provided with a square groove. The outer wall of the guide block 8 is embedded in the square groove and slidably connected to it. The lifting structure 7 is designed to ensure stable cutting. When the electric telescopic rod is activated, the cutting structure 5 descends, allowing the two cutting wheels to smoothly contact the ground and cut. The two parallel guide rails eliminate the need for manual control of the cutting depth; parallel cutting can be achieved simply by pushing the device. The operation is simple and convenient. Since the two parallel guide rails cross the broken area, and the road surface was initially constructed with a certain degree of flatness, the above operation method can effectively assist the cutting structure 5 in cutting without significant deviation. Even if a slight deviation occurs, it will not affect the normal progress of the repair work.

[0031] The cutting structure 5 is inverted U-shape. A drive motor 13 is fixedly installed on the inner wall of one side of the cutting structure 5. A drive gear 14 is fixedly installed at the output end of the drive motor 13. A driven gear ring 15 is meshed at the bottom end of the drive gear 14. A rotating shaft 16 is fixedly embedded in the center of the side wall of the driven gear ring 15. The two ends of the rotating shaft 16 are rotatably connected to the two side walls of the cutting structure 5, respectively. A first cutting disc 17 and a second cutting disc 18 are installed on the rotating shaft 16. When the drive motor 13 is started, the drive motor 13 drives the drive gear 14 to rotate. The drive gear 14 drives the driven gear ring 15 to rotate. The driven gear ring 15 drives the rotating shaft 16 to rotate. The rotating shaft 16 drives the first cutting disc 17 and the second cutting disc 18 to rotate, thereby completing the cutting work.

[0032] An adjustment structure 19 is provided inside the rotating shaft 16. The adjustment structure 19 includes a cavity, and an adjustment rod 21 is rotatably connected inside the cavity. One end of the adjustment rod 21 extends out of the rotating shaft 16 and is rotatably connected thereto. A fixing plate 20 is fixedly connected between the two inner walls of the cavity. Two T-shaped rods 46 are inserted into the fixing plate 20. Tension springs 47 are sleeved on the T-shaped rods 46. An arc-shaped clamping plate 48 is fixedly connected to the top of the T-shaped rods 46. Annular grooves 44 are provided on the inner ring walls of the first cutting disc 17 and the second cutting disc 18. An arc-shaped groove 45 is provided on the inner top surface of the cavity. The arc-shaped clamping plate 48 can slide within the arc-shaped groove 45. Two first top blocks 43 are fixedly installed on the top of the adjustment rod 21. The top block 43 is located on the same horizontal plane and is fitted to the bottom end of the corresponding T-shaped rod 46. The bottom end of the adjusting rod 21 is fixedly connected to the second top block 49 and the third top block 50. The second top block 49 and the third top block 50 are respectively set below the corresponding first top block 43. The second top block 49 and the third top block 50 are both inclined in opposite directions. The adjusting structure 19 plays an adjusting role and is an important component that allows the first cutting disc 17 and the second cutting disc 18 to be used alternately or simultaneously. The specific usage method is as follows: when cutting is initially performed, the first cutting disc 17 and the second cutting disc 18 rotate simultaneously. At this time, the two first top blocks 43 contact the bottom end of the T-shaped rod 46 (see attached). Figure 8This causes the T-shaped rod 46 to move, prompting the arc-shaped clamping plate 48 to extend into the arc-shaped groove 45 and then into the corresponding annular groove 44 within the cutting disc for engagement. This causes the rotating shaft 16 to rotate synchronously with the first cutting disc 17 and the second cutting disc 18, thus cutting out two lines during the initial cutting process. The asphalt between the two lines is then cleaned by the cleaning structure 22. After moving to one side, i.e., after the first cut is completed, since the asphalt pavement on one side of the road surface to be repaired has been removed, the adjusting rod 21 is adjusted so that the second top block 49 contacts the corresponding T-shaped rod 46. Since the offset directions of the second top block 49 and the third top block 50 are opposite and not on the same straight line, the arc-shaped clamping plate 48 at the second top block engages with the corresponding annular groove 44, thereby allowing the second cutting disc 18 to advance. As the first cutting disc rotates, the arc-shaped clamping plate 48 separates from the annular groove 44 under the action of the tension spring 47 and retracts into the arc-shaped groove 45, thus not affecting the rotation of the first cutting disc 17. In other words, the first cutting disc 17 and the rotating shaft 16 rotate together, and the two are movably connected. Moving the two guide rails to one side makes the first cutting disc 17 contact the side wall of the area being cleaned. In this way, the first cutting disc 17 is equivalent to a limiting disc, so that each cutting operation will cut a similar distance. When the second cutting disc 18 gets hot after a period of use, it can be adjusted to allow the first cutting disc 17 to rotate through the adjusting rod 21. At the same time, the adjusting plate 6 should be adjusted to 180 degrees and locked. This will allow it to work normally, and the two cutting discs can be used alternately, which can extend their service life to a certain extent.

[0033] A cleaning structure 22 is fixedly installed on the inner top surface of the cutting structure 5. The cleaning structure 22 includes a connecting frame, and a first hydraulic cylinder 23 is fixedly installed at the bottom end of the connecting frame. The first hydraulic cylinder 23 is inclined, and a movable frame 24 is fixedly connected to the output end of the first hydraulic cylinder 23. The movable frame 24 is parallel to the ground and is in a horizontal U-shape. Multiple rolling balls are embedded at the bottom end of the movable frame 24. A second hydraulic cylinder 27 is fixedly installed on one inner wall of the movable frame 24. A spring cylinder 28 is fixedly installed at the output end of the second hydraulic cylinder 27. A dovetail groove 25 is provided on the inner top surface of the movable frame 24. A dovetail block 26 is slidably connected in the dovetail groove 25. A shovel block 29 is fixedly installed at the bottom end of the dovetail block 26. The shovel block 29 is inclined and has a U-shape. A heating block 33 is fixedly installed inside the shovel block 29. A cylinder 32 is fixedly installed on one inner wall of the shovel block 29. A connecting plate 31 is fixedly connected to the output end of the cylinder 32. One side of the connecting plate 31... Multiple insert rods 30 are fixedly connected to the side. A third hydraulic cylinder 34 is fixedly connected to one side of the bottom of the connecting frame. A cutter 35 is fixedly connected to the output end of the third hydraulic cylinder 34. The cutter 35 is L-shaped. When cleaning, the first hydraulic cylinder 23 is activated to lower the connecting frame, so that the shovel block 29 extends into the ground and shovels. At the same time, a ball bearing and a heating block 33 are also provided at the bottom of the moving frame 24, which can soften the asphalt pavement to a certain extent, so that the asphalt pavement can be shoveled up smoothly. In order to further ensure the smooth progress of the shoveling work, multiple insert rods 30 are provided. The multiple insert rods 30 are rapidly pulled by the cylinder. As the cutting structure 5 moves slowly, the multiple insert rods 30 are always rapidly pulled up, so that the asphalt pavement at the current position is evenly inserted into multiple holes at close intervals. In this way, when the shovel block 29 shovels, some effort can be saved, thereby avoiding affecting the overall movement efficiency and enabling the cutting and cleaning work to be carried out smoothly.

[0034] The spring cylinder 28 consists of an outer cylinder, a spring, and a limiting slide rod. One end of the outer cylinder is fixedly connected to the output end of the second hydraulic cylinder 27, and one end of the limiting slide rod is fixedly connected to one side of the shovel block 29. The spring cylinder 28 plays a certain buffering role because, in the initial shoveling stage, the asphalt pavement is not fully heated, resulting in a hard pavement that cannot be easily shoveled. Therefore, the spring cylinder 28 is set to buffer the pavement, allowing the shovel block 29 to stay in the current position for a while. Also, since the entire cutting process moves relatively slowly, a certain amount of time is allowed for the initial asphalt pavement to be heated and softened, making it easier for the shovel block 29 to perform the cleaning work.

[0035] The heating structure 37 is L-shaped. A fourth hydraulic cylinder 36 is fixedly installed at the top of the heating structure 37. The top of the fourth hydraulic cylinder 36 is fixedly connected to the inner top surface of the cutting structure 5. An installation groove 38 is provided inside the heating structure 37. Positioning grooves 41 are provided on both sides of the inner wall of the installation groove 38. Positioning blocks 42 are slidably connected in the positioning grooves 41. The rotating shaft 16 passes through the installation groove 38. A heat-conducting block 40 is slidably connected in the installation groove 38. The two sides of the heat-conducting block 40 are fixedly connected to the side walls of the corresponding positioning blocks 42. A compression spring 39 is fixedly connected to the top of the heat-conducting block 40. The top of the compression spring 39 is fixedly connected to the inner top surface of the heating structure 37. The heating structure 37 serves to heat the asphalt pavement and soften it. The fourth hydraulic cylinder 36 is activated. After cylinder 36, the heating structure 37 comes into contact with the road surface, and a compression spring 39 is provided to ensure that the heating structure 37 can maintain good contact with the ground, thereby softening the road surface. The heating structure uses electric heating and is filled with water to keep the temperature at a controllable level, avoiding excessive softening and stickiness of the road surface due to overheating. At the same time, a heat-conducting block 40 is provided to transfer the heat generated by the frictional rotation of the rotating shaft 16 to the heating structure 37, saving some energy. Meanwhile, the rotating shaft 16 can slide in the mounting groove, so even if the heating structure 37 rises or falls due to ground depressions or protrusions, it will not affect the normal operation of the rotating shaft 16.
