Description

Technical Field

[0001] This invention belongs to the field of asphalt pavement maintenance technology, and in particular relates to a rapid repair device and repair method for asphalt pavement maintenance. Background Technology

[0002] Asphalt is a complex, dark brown mixture composed of hydrocarbons of varying molecular weights and their non-metallic derivatives. It is a high-viscosity organic liquid, mostly existing in liquid or semi-solid petroleum form, with a black surface. It is soluble in carbon disulfide and carbon tetrachloride. Asphalt is a waterproof, moisture-proof, and corrosion-resistant organic cementing material. Asphalt can be mainly divided into three types: coal tar pitch, petroleum asphalt, and natural asphalt. Coal tar pitch is a byproduct of coking; petroleum asphalt is the residue after crude oil distillation; and natural asphalt is stored underground, sometimes forming mineral layers or accumulating on the earth's surface. Asphalt is mainly used in industries such as coatings, plastics, and rubber, as well as for road paving. During long-term use, asphalt pavements are subjected to continuous vehicle loads and seasonal temperature and humidity changes, leading to wear, aging, and damage. This damage is mainly manifested in the formation and expansion of cracks, such as transverse cracks, longitudinal cracks, and network cracks. The appearance of cracks not only affects the smoothness of the road surface and driving comfort but also further leads to water infiltration, eroding the roadbed structure and accelerating pavement damage. To ensure the normal function of asphalt pavements, extend their service life, and minimize maintenance costs, specialized repair measures for cracks are typically adopted. Crack repair is an efficient and economical maintenance method; it is simple to construct, quick to repair, and can promptly restore the continuity and waterproofing performance of the pavement. Through scientific and reasonable crack treatment, not only can small defects be prevented from developing into major problems, but maintenance expenditures throughout the entire life cycle can also be significantly reduced, improving the safety and economy of road use.

[0003] Existing rapid repair devices for asphalt pavement maintenance require manual pre-laying of asphalt on the pavement to be repaired, followed by manual smoothing, and finally, the use of equipment to compact the asphalt at the repair area to complete the crack repair. This crack repair process not only results in a large workload for manual workers but also leads to poor continuity of the repair process, thereby reducing the efficiency and quality of asphalt crack repair. To address these issues, we provide a rapid repair device and method for asphalt pavement maintenance. Summary of the Invention

[0004] The purpose of this invention is to provide a rapid repair device and method for asphalt pavement maintenance. By setting up a smoothing component and a compaction component, the smoothing plate is controlled to move back and forth, scraping the freshly laid asphalt back and forth, thus making the asphalt surface smoother. Simultaneously, the smoothing component's left and right movement, through the control of the support rod's reciprocating swing, drives the pendulum rod to move up and down, which in turn drives the compaction plate to continuously pat the asphalt, making the asphalt more compact and improving the quality of pavement repair. With the combined use of the material feeding and compaction component, the smoothing component, and the compaction component, the asphalt is evenly distributed, reducing labor intensity, and the smoothing and compaction processes are highly consistent, effectively improving the efficiency and quality of pavement repair. This invention solves the problem that existing rapid repair devices for asphalt pavement maintenance require manual pre-laying of asphalt on the pavement to be repaired, followed by manual smoothing, and finally, the use of equipment to compact the asphalt at the repair site to complete the crack repair. This crack repair process not only results in a large workload for manual labor but also leads to poor continuity in the repair process, thus reducing the efficiency and quality of asphalt crack repair.

The pressing assembly also includes two L-shaped guide plates fixedly connected to the top of the operating table, and the L-shaped guide plates slide in cooperation with the pressure rod. A PLC controller is installed inside the control panel, and the PLC controller is electrically connected to the motor through wires.

[0014] This invention also includes a rapid repair method for asphalt pavement maintenance, comprising the following steps: S01: First, the asphalt is put into the storage box. Then, by controlling the two washboards to move back and forth inside the conical guide box, the washboards continuously rub the asphalt inside, preventing the asphalt from accumulating at the discharge port during the asphalt discharge process, thus ensuring the smooth discharge of asphalt.

[0015] S02: Next, after the asphalt is poured onto the road surface to be repaired, the smoothing plate is controlled to move back and forth along the forward direction of the device, so that the smoothing plate can scrape the asphalt and improve the smoothness of the repair area.

[0016] S03: Then, control the tamping plate in the tamping component to move up and down repeatedly, so that the tamping plate tamps the asphalt, making the asphalt more compact and improving the strength of the repair.

[0017] S04: Finally, by controlling the rotation of the compaction roller, and simultaneously moving the device, the compaction roller compacts and tamps the road surface to be repaired, thereby completing the road surface repair.

[0018] The present invention has the following beneficial effects: 1. By setting up a smoothing component and a compaction component, the present invention controls the smoothing plate to move back and forth left and right, so that the freshly laid asphalt is scraped back and forth by the smoothing plate, thereby making the asphalt surface smoother. At the same time, the smoothing component moves back and forth left and right, so that it controls the swinging rod to move back and forth up and down through the swinging rod, thereby driving the compaction plate to continuously pat the asphalt, making the asphalt more compact, thereby improving the quality of road repair. With the use of the material feeding and compaction component, the smoothing component and the compaction component in combination, the asphalt is fed evenly, reducing the amount of labor, and the smoothing and compaction are highly consistent, effectively improving the efficiency and quality of road repair.

[0019] 2. This invention controls the screw to rotate clockwise, driving the moving plate away from the storage box. Through the second connecting plate and support rod, the first connecting plate is also moved away from the storage box. The first connecting plate then drives two rubbing plates to the left via two sliding rods. Controlling the screw to rotate counterclockwise drives the moving plate towards the storage box. Through the second connecting plate and support rod, the first connecting plate is also moved closer to the storage box. The first connecting plate then drives two rubbing plates to the right via two sliding rods. The two rubbing plates reciprocate inside the conical guide box, rubbing the asphalt inside the storage box to prevent clogging at the outlet, ensuring the asphalt is evenly distributed to the road repair area and guaranteeing the quality of the road repair. Simultaneously, after the asphalt is laid on the road surface to be repaired, it is processed by the smoothing and compaction components. The first sprocket is simultaneously controlled to rotate, driving the second rotating shaft and the compaction roller to rotate. The compaction roller then compacts the asphalt, thus completing the road repair.

[0020] 3. This invention controls the motor to start, which drives the rotating rod to rotate via the output shaft. The rotation of the rotating rod further drives the connected turntable to rotate synchronously. During the rotation of the turntable, the second connecting column installed on the edge of the turntable moves in a uniform circular motion. This circular motion is converted into the periodic left and right swing of the support rod through the linkage mechanism. The swing of the support rod provides stable and reliable reciprocating linear motion power for the flat plate, ensuring that it can achieve precise left and right movement. At the same time, during the rotation of the rotating rod, the second sprocket installed at the end of the rotating rod is also driven to rotate coaxially. The second sprocket and the first sprocket form a complete chain drive system through the transmission chain, effectively transmitting power to the drive shaft of the compaction roller. The rotation of the first sprocket directly drives the compaction roller to rotate, thus providing a continuous and stable power source for the entire compaction process and ensuring the coordinated operation of the various components of the system.

[0021] 4. This invention controls the servo motor to drive the rotating plate to reciprocate, and then uses two moving blocks and pressure rods to drive the two pressure plates to move up and down alternately. This allows the pressure plates to press the asphalt inside the storage box, so that the asphalt inside the storage box can be discharged more smoothly and ensure continuous asphalt feeding.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1, please refer to Figure 1-10 The present invention provides the following technical solution: a rapid repair device for asphalt pavement maintenance, comprising a material feeding and compaction assembly 1, a smoothing assembly 2 disposed on the material feeding and compaction assembly 1, a compaction assembly 3 disposed on one side of the smoothing assembly 2 disposed on the material feeding and compaction assembly 1, a drive assembly 4 disposed on the material feeding and compaction assembly 1, and a pressing assembly 5 disposed on the top of the material feeding assembly 1; the material feeding and compaction assembly 1 is used for feeding and compacting asphalt; the smoothing assembly 2 smooths the asphalt after feeding, making the road surface flat; the compaction assembly 3 is used for compacting the asphalt, making the asphalt more compact; the drive assembly 4 provides power for the material feeding and compaction assembly 1, the smoothing assembly 2, and the compaction assembly 3 to work synchronously.

[0026] The material feeding and compaction assembly 1 includes an operating table 101. Several support columns 102 are symmetrically fixedly connected to the bottom of the operating table 101. Pulleys 103 are installed at the bottom of the support columns 102. First vertical plates 104 are symmetrically fixedly connected to the top of the operating table 101. Handles 105 are fixedly connected between the two first vertical plates 104. A control panel 106 is fixedly connected to the top of the operating table 101. A storage box 107 is fixedly connected through the top of the storage box 101. A conical guide box 108 is fixedly connected to the bottom of the storage box 107. A slidable scooping board 109 is symmetrically slidably connected to the bottom of the conical guide box 108. Several friction balls 110 are evenly fixedly connected to the top of the scooping board 109. A sliding rod 111 that slides through the conical guide box 108 is fixedly connected to one side of the scooping board 109. A first connecting plate 112 is fixedly connected between the two sliding rods 111. A support rod 113 is fixedly connected to the top of the first connecting plate 112. A second connecting plate 114 is fixedly connected to the top of the support rod 113.

[0027] A lead screw 115 is rotatably connected to one outer side of the storage box 107. A first spur gear 116 is fixedly connected to the outer wall of the lead screw 115. A movable plate 117 is threadedly connected to the outer wall of the lead screw 115. The movable plate 117 is fixedly engaged with the second connecting plate 114. A first baffle 118 is fixedly connected to the end of the lead screw 115. A second upright plate 119 is symmetrically fixedly connected to the bottom of the operating table 101. A second rotating shaft 120 is rotatably connected to one side of the second upright plate 119. A crushing roller 121 is fixedly connected between the two second rotating shafts 120. A first sprocket 122 is fixedly connected to the end of one of the second rotating shafts 120. A sliding groove 123 is symmetrically opened at the bottom of the operating table 101.

[0028] The operation process in this embodiment is as follows: Figure 4-5 As shown, firstly, the entire device is smoothly moved to the specific location on the ground to be repaired. The device's orientation is precisely adjusted to ensure complete alignment with the area to be treated, achieving the best repair effect. Then, pre-mixed asphalt material is evenly poured into the storage box 107, completing the filling operation and confirming that the material is fully filled. Next, the control system issues a command to cause the lead screw 115 to rotate clockwise at a uniform speed. This rotation stably drives the moving plate 117 to move smoothly away from the storage box 107, forming an initial displacement. The movement of the moving plate 117 further utilizes the linkage between the second connecting plate 114 and the support rod 113 to coordinate and drive the first connecting plate 112 to move synchronously away from the storage box 107, achieving effective force transmission. The displacement of the first connecting plate 112 is transmitted to the two washboards 109 through two symmetrically arranged sliding rods 111, causing them to move stably to the left as a whole, completing one working stroke. Subsequently, the control system commands the lead screw 115 to rotate counterclockwise. At this time, the moving plate 117 smoothly retracts towards the storage box 107, achieving reverse movement. Similarly, through the mechanical cooperation between the second connecting plate 114 and the support rod 113, the first connecting plate 112 also moves towards the storage box 107, thereby driving the two rubbing plates 109 to move to the right, forming a reverse stroke. Through the continuous and rhythmic reciprocating motion of the two rubbing plates 109 inside the conical guide box 108, the asphalt material contained in the storage box 107 is constantly rubbed and loosened, effectively preventing asphalt from accumulating or clogging in the outlet area of ​​the conical guide box 108 due to temperature changes or material characteristics. This series of coherent and coordinated actions ensures that the asphalt material always falls smoothly, stably, and controllably downwards, ultimately achieving a uniform, continuous, and consistent thickness of asphalt laid on the ground at the repair location, significantly improving the consistency and efficiency of the repair work, as well as the overall quality and durability of the road repair. At the same time, after the asphalt is laid on the road surface to be repaired, it is smoothed and compacted by the smoothing component 2 and the compaction component 3. Simultaneously, the first sprocket 122 is controlled to rotate, so that the first sprocket 122 drives the second rotating shaft 120 to rotate, which in turn drives the rolling roller 121 to rotate, so that the rolling roller 121 rolls the asphalt, thereby completing the repair of the road surface to be repaired.

[0029] Example 2, please refer to Figure 1-10This second embodiment is an improvement on the first embodiment as follows: the smoothing component 2 includes two sliding plates 201 slidably connected to the bottom of the operating table 101. The sliding plates 201 are slidably engaged with the corresponding sliding grooves 123. A vertical plate 202 is fixedly connected between the two sliding plates 201. A first fixing plate 203 is symmetrically fixedly connected to the bottom of the vertical plate 202. A smoothing plate 204 is rotatably connected between the two first fixing plates 203. A limiting plate 205 that abuts against the smoothing plate 204 is fixedly connected to the bottom of the vertical plate 202. A first connecting post 206 is fixedly connected to one side of the vertical plate 202. A sleeve 207 is rotatably connected to the outer wall of the first connecting post 206. A support rod 208 is fixedly connected to the outer wall of the sleeve 207. A toothed plate 209 is fixedly connected to an adjacent side of the vertical plate 202. The toothed plate 209 meshes with a first spur gear 116.

[0030] The compaction component 3 includes an L-shaped plate 301 fixedly connected to the bottom of the operating table 101. A rectangular sleeve 302 is fixedly connected to the end of the L-shaped plate 301. A square rod 303 is slidably connected to the inner wall of the rectangular sleeve 302. A compaction plate 304 is fixedly connected to the bottom of the square rod 303. An extension plate 305 is fixedly connected to one side of the square rod 303. A swing rod 306 is hinged to the bottom of the extension plate 305. The swing rod 306 is hinged to the support rod 208.

[0031] The operation process in this embodiment is as follows: Figure 7-8 As shown, by adjusting the support rod 208 to move to the left, the sleeve 207 is moved to the left in sync, thereby pulling the first connecting column 206 to swing to the left. This series of actions further causes the vertical plate 202 to move to the left. The movement of the vertical plate 202 directly drives the smoothing plate 204 to move to the left. During the leftward movement of the smoothing plate 204, if it encounters a protruding part of the asphalt surface, the smoothing plate 204 will be lifted upward due to contact with the protruding asphalt, causing it to rotate away from the limiting plate 205. This rotation mechanism ensures that the smoothing plate 204 will not bring the asphalt material back to the treated area when it moves in the opposite direction, thereby effectively maintaining the regularity and consistency of the asphalt surface smoothing. Correspondingly, when the control strut 208 moves to the right, the strut 208 drives the first connecting column 206 to swing to the right through the sleeve 207, thereby pushing the vertical plate 202 to move to the right. The rightward movement of the vertical plate 202 further drives the smoothing plate 204 to move to the right. During this process, if the smoothing plate 204 comes into contact with the asphalt protrusion, the asphalt will abut against the smoothing plate 204, causing it to rotate towards the limiting plate 205 until the smoothing plate 204 abuts against the limiting plate 205. At this time, the smoothing plate 204 is in a vertical state, thereby completing the effective smoothing of the asphalt, ensuring that the asphalt surface is flat and smooth, and significantly improving the overall quality and use effect after the ground repair. By controlling the vertical plate 202 to move back and forth, the vertical plate 202 synchronously drives the toothed plate 209 connected to it to move back and forth accordingly, so that the toothed plate 209 can accurately mesh and drive the first spur gear 116 to perform reciprocating rotational motion, providing a continuous and stable power source for the reciprocating rotation of the first spur gear 116. By controlling the support rod 208 to swing back and forth left and right, it drives the pendulum rod 306 to swing up and down accordingly. Specifically, when the support rod 208 swings to the left, it pulls the pendulum rod 306 to swing down; when the support rod 208 swings to the right, it pulls the pendulum rod 306 to swing up. In this way, each time the support rod 208 completes one cycle of left and right swing, it drives the pendulum rod 306 to complete one complete cycle of up and down reciprocating swing. Subsequently, the movement of the pendulum rod 306 is transmitted to the square rod 303 through the extension plate 305, causing it to move up and down reciprocally. During the up and down movement of the square rod 303, it further drives the compaction plate 304 to move forward. The reciprocating up-and-down movement of the compactor 304 allows it to continuously pound the asphalt material. This continuous pounding effectively eliminates voids between asphalt particles, making the asphalt particles more tightly bonded and significantly improving the compaction and repair quality of the road surface. Throughout the road repair process, the material feeding and compaction component 1, the smoothing component 2, and the compactor 3 work together to achieve uniform asphalt feeding, greatly reducing the labor intensity of manual operation. At the same time, the high continuity and seamless connection between the components not only significantly improve the overall efficiency of road repair but also further ensure the smoothness and durability of the repaired road surface, thereby comprehensively optimizing the quality and effect of the repair operation.

[0032] Example 3, please refer to Figure 1-10 This third embodiment is an improvement on the first embodiment as follows: the drive assembly 4 includes a column 401 fixedly connected to the bottom of the operating table 101, a mounting base 402 fixedly connected to the bottom of the column 401, a motor 403 fixedly connected to the bottom of the mounting base 402, a rotating rod 404 fixedly connected to the output end of the motor 403, a turntable 405 fixedly connected to the end of the rotating rod 404, a second connecting column 406 fixedly connected to one side of the turntable 405 off-center, the second connecting column 406 rotatably engages with the support rod 208, and a second baffle 407 is fixedly connected to the end of the second connecting column 406; a second sprocket 408 is fixedly connected to the outer wall of the rotating rod 404, and a chain meshes between the second sprocket 408 and the first sprocket 122.

[0033] The operation process of this embodiment is as follows: By controlling the operation of the motor 403, the rotating rod 404 is driven to rotate, thereby causing the rotating rod 404 to drive the turntable 405 connected to it to rotate synchronously; the rotation of the turntable 405 further drives the second connecting column 406 to make a circular motion around the center of the turntable 405. During the rotation, the second connecting column 406, through its mechanical connection with the support rod 208, drives the support rod 208 to swing periodically left and right, thereby providing a continuous and stable power source for the support rod 208 to drive the flat plate 204 to move back and forth. At the same time, during the rotation of the rotating rod 404, it also drives the second sprocket 408 installed on it to rotate together; the second sprocket 408 transmits power to the first sprocket 122 through the chain transmission mechanism, and drives the first sprocket 122 to rotate accordingly; through the rotation of the first sprocket 122, the rolling roller 121 connected to it is further driven to rotate, thereby providing reliable and coordinated power support for the rotation of the rolling roller 121.

[0034] Example 4, please refer to Figure 1-10 This third embodiment is an improvement on the first embodiment as follows: The pressing component 5 includes an L-shaped load-bearing plate 501 fixedly connected to the top of the operating table 101. A servo motor 502 is fixedly connected to one side of the L-shaped load-bearing plate 501. A rotating plate 503 is fixedly connected to the output end of the servo motor 502. A guide groove 504 is symmetrically opened at the bottom of the rotating plate 503. A moving block 505 is slidably connected to the inner wall of the guide groove 504. A pressure rod 506 is hinged to the bottom of the moving block 505. A pressure plate 507 is fixedly connected to the bottom end of the pressure rod 506. The pressing component 5 also includes two L-shaped guide plates 508 fixedly connected to the top of the operating table 101. The L-shaped guide plates 508 and the pressure rod 506 are slidably engaged. A PLC controller is installed inside the control panel 106.
