Description

Technical Field

[0001] This invention relates to the field of road repair technology, specifically to a rapid repair device for asphalt pavement cracks. Background Technology

[0002] Frequent vehicle traffic loads put stress on asphalt pavements, especially in high-load areas such as highways or busy urban roads. This stress causes deformation and wear on the asphalt surface, leading to cracks in the pavement. Therefore, asphalt pavement repair devices are needed, but existing repair devices still have some shortcomings.

[0003] For example, CN116289462A discloses an asphalt pavement repair device. The multiple rollers of the compaction mechanism can be adjusted according to the width of the pothole; therefore, even in narrower potholes, some rollers can extend into the pothole to compact the asphalt. The guiding component can move the compaction mechanism along the curvature of the pothole, allowing the multiple rollers to compact the asphalt more flexibly. While the above device can compact asphalt, it cannot adaptively adjust the asphalt pouring trajectory according to the crack path when used for larger cracks. Furthermore, existing pavement repair devices cannot adjust the asphalt pouring flow rate as needed, nor can they adaptively adjust the pouring flow rate according to the width of the crack. During the pouring process, the subsequent paving area cannot be adjusted according to the crack width, and asphalt cleaning of the paving components is not possible after the work is completed. Summary of the Invention

[0004] In view of the problems existing in the road repair device, the present invention is proposed.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a rapid repair device for asphalt pavement cracks, comprising a housing, support rods installed around the housing, casters installed at the bottom of the support rods, a connecting pipe and a fixing rod fixedly installed at the bottom of the housing, the housing and the connecting pipe being interconnected, an outer shell fixedly connected to the fixing rod, a baffle plate connected to the top of the outer shell, a side plate installed on the outer shell, a protruding plate fixedly connected to the bottom of the side plate, a connecting plate fixedly installed on the side plate, a motor installed on the right side of the side plate, a connecting shaft connected to the output shaft of the motor, a partition plate installed on the connecting shaft, an adjusting plate provided on the outer side of the partition plate, a guide assembly installed on the adjusting plate, a connecting groove opened in the middle of the adjusting plate, an inner groove opened inside the outer shell for the connecting shaft and the partition plate to rotate and for the adjusting plate to slide, an opening opened at the bottom of the outer shell, a base plate rotatably arranged below the adjusting plate, a receiving box installed below the base plate, and a material injection assembly installed between the receiving box and the connecting plate.

[0006] As a preferred embodiment of the present invention, the housing, support rod, connecting pipe, fixing rod and outer shell are an integral unit, the connecting pipe is located between two adjacent baffles, and the connecting pipe is interconnected with the interior of the outer shell through the baffles.

[0007] As a preferred embodiment of the present invention, a sliding rod is slidably connected between two adjacent support rods, and a sliding plate is fitted inside the sliding rod. The width of the sliding plate is smaller than the distance between the two adjacent support rods. A groove is provided on the sliding plate, and a damping block is installed in the groove. Multiple protruding rods with varying heights are provided above the sliding plate, and the protruding rods are fixedly connected to the box body.

[0008] As a preferred embodiment of the present invention, the lower surface of the outer shell and the upper surface of the receiving box are fitted together, the width of the receiving box is greater than the width of the opening, and the inner wall of the receiving box and the outer wall of the protruding plate are fitted together.

[0009] As a preferred embodiment of the present invention, the inner wall of the connecting groove is in contact with the outer wall of the connecting shaft and the partition, and the partition is evenly distributed along the circumference of the connecting shaft.

[0010] As a preferred embodiment of the present invention, the guide assembly includes a rotating groove formed on the side of the adjusting plate, a connecting block being fitted into the rotating groove, a first guide plate being fixedly connected above the connecting block, a second guide plate and an extension plate being fixedly disposed on the first guide plate, and a moving groove for the extension plate to slide on the top of the outer shell.

[0011] As a preferred embodiment of the present invention, the second guide plate is symmetrically distributed on the first guide plate, the first guide plate is inclined, the sides of the second guide plate and the baffle are in contact with each other, and the connecting block, the first guide plate, the second guide plate and the extension plate are integrally formed.

[0012] As a preferred embodiment of the present invention, the injection assembly includes a fixing block fixedly installed at the bottom of the connecting plate, a ball bearing rotatably mounted on the fixing block, a corrugated steel pipe fixedly disposed on the fixing block, a heat insulation pipe connected to the left side of the corrugated steel pipe, the top of the heat insulation pipe being connected to the receiving box, and the bottom of the corrugated steel pipe having a through structure.

[0013] As a preferred embodiment of the present invention, a spring is installed between the fixing block and the heat insulation pipe. The spring is made of alloy steel. A connecting block is installed at the bottom of both the fixing block and the heat insulation pipe. The thickness of the connecting block decreases from top to bottom.

[0014] As a preferred embodiment of the present invention, the balls are evenly distributed on the fixed block, and the balls protrude from the surface of the fixed block.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. Through the designed injection components, the device can adapt to gaps of different widths for asphalt injection during operation using a retractable corrugated steel pipe. Furthermore, during movement, the device can be aligned by placing the ball-bearing side of the fixed block against one side of the gap's inner wall, and then attaching the insulation pipe to the other side of the gap. This allows the entire device to move along the gap's trajectory, achieving adaptive adjustment of the asphalt injection path. This solves the problem of existing repair devices being unable to move along the gap's trajectory, making the device significantly more convenient to use.

[0017] 2. Through the adjusting plate and guiding components on the device, under the elasticity of the corrugated steel pipe itself and the action of the spring, the corrugated steel pipe can push the heat insulation pipe to the left, thereby causing the adjusting plate to move on the connecting shaft and partition through the connecting groove, which increases the injection rate of the device. This allows the device to increase the main material speed when injecting asphalt in areas with larger gaps, solving the problem that existing road repair devices cannot adjust the flow rate of asphalt pouring as needed. This device has the advantage of stronger functionality and can adaptively adjust the movement trajectory and pouring speed.

[0018] 3. The device features a sliding plate and a sliding rod, allowing the sliding plate to move up and down along the support rod. As the device moves along the casters, it automatically smooths out any spilled asphalt, ensuring a flat top for the cracks. This solves the problem that existing road repair devices cannot automatically smooth out the asphalt after it has been injected. This device can maintain the aesthetic appearance of the road surface after repair.

[0019] 4. With the set slide plate, slide bar and convex bar, the device can move the slide plate up and down after the work is completed, so that the slide bar in the slide plate can be intermittently contacted with the ground and the convex bar, thereby causing displacement between adjacent convex bars. This prevents the asphalt from sticking to the slide bar used for paving after the work is completed, ensuring the stable use of the device. In addition, the device can also use multiple slide bars arranged in parallel to adapt to gaps of different widths for paving work. Attached Figure Description

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0036] Example

[0037] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0038] like Figures 1-11 As shown, a rapid repair device for asphalt pavement cracks includes a housing 1. Support rods 2 are installed around the housing 1, and casters 3 are installed at the bottom of the support rods 2. The casters 3 facilitate the movement of the housing 1 along the crack by the operator. A connecting pipe 4 and a fixing rod 5 are fixedly installed at the bottom of the housing 1, and the housing 1 and the connecting pipe 4 are interconnected. A shell 6 is fixedly connected to the fixing rod 5. Asphalt inside the housing 1 can be injected into the shell 6. By adjusting the flow rate, it can adapt to cracks of different widths. A baffle 7 is connected to the top of the shell 6, and a side plate 8 is installed on the shell 6. The side plate 8 can close the right side of the shell 6. A protruding plate 18 is fixedly connected to the bottom of the side plate 8, and a connecting plate 19 is fixedly installed on the side plate 8. A motor 9 is installed on the right side of the side plate 8, and a connecting shaft 10 is connected to the output shaft of the motor 9. A partition 11 is installed on the connecting shaft 10. The motor 9 drives the connecting shaft 10 and the partition 11 to rotate. When the partition 11 rotates, asphalt can be conveyed downward through the partition 11. An adjusting plate 12 is provided on the outside of the partition 11, and a guide component 14 is installed on the adjusting plate 12. A connecting groove 13 is opened in the middle of the adjusting plate 12. An inner groove 16 is opened inside the outer shell 6 for the connecting shaft 10 and the partition 11 to rotate and for the adjusting plate 12 to slide. An opening 17 is opened at the bottom of the outer shell 6. A base plate 22 is rotatably provided below the adjusting plate 12. A receiving box 21 is installed below the base plate 22. An injection component 20 is installed between the receiving box 21 and the connecting plate 19. During operation, the speed of the motor 9 remains constant. When the gap widens, the width of the injection component 20 increases, pushing the adjusting plate 12 to slide on the partition 11, thereby causing the adjusting plate 12 to move to the left as a whole, which increases the asphalt flow rate of the device. The injection component 20 can abut against both sides of the gap, and with the universal wheel 3, the device can move accurately along the track of the gap.

[0039] In this embodiment, the box 1, support rod 2, connecting pipe 4, fixing rod 5 and outer shell 6 are an integral unit. The box 1 is used to inject heated asphalt into the outer shell 6. The connecting pipe 4 is located between two adjacent baffles 7. The connecting pipe 4 is interconnected with the interior of the outer shell 6 through the baffles 7, ensuring that the connecting pipe 4 can deliver asphalt into the interior of the outer shell 6. The baffles 7 can prevent asphalt from flowing out from the top of the outer shell 6.

[0040] In this embodiment, a sliding rod 24 is slidably connected between two adjacent support rods 2. A sliding plate 23 is fitted inside the sliding rod 24. The width of the sliding plate 23 is smaller than the distance between the two adjacent support rods 2, ensuring that after the asphalt flows downward into the gap, the weight of the sliding plate 23 allows the device to flatten the top of the gap, ensuring the stability of the device during operation. A groove 25 is provided on the sliding plate 23, and a damping block 26 is installed in the groove 25. The damping block 26 can support two adjacent sliding plates 23. The leftmost and rightmost sliding plates 23 are fixedly connected to the sliding rod 24. Next, the remaining slide plates 23 and slide rods 24 are slidably connected to each other, so as to adjust the contour of the multiple slide plates 23 in the future, thereby paving asphalt road gaps of different widths. Multiple convex rods 27 with varying heights are set on the top of the slide plates 23. The convex rods 27 and the box body 1 are fixedly connected. After the work is completed, the slide plates 23 can be pulled up and down, so that the slide rods 24 on the slide plates 23 can intermittently contact the ground and the convex rods 27, thereby enabling the device to clean the adhesive asphalt material and prevent adjacent slide rods 24 from sticking together.

[0041] In this embodiment, the lower surface of the outer shell 6 is in contact with the upper surface of the receiving box 21. The width of the receiving box 21 is greater than the width of the opening 17. The inner wall of the receiving box 21 is in contact with the outer wall of the protruding plate 18. The mutual contact of the protruding plate 18 and the receiving box 21 ensures that the asphalt will not flow out during the movement of the receiving box 21, thus ensuring the stability of the device during operation.

[0042] In this embodiment, the inner wall of the connecting groove 13 is in contact with the outer wall of the connecting shaft 10 and the partition 11. The partition 11 is evenly distributed along the circumference of the connecting shaft 10. The partition 11 can realize the unloading function during rotation. The larger the exposed area of ​​the partition 11, the more the device can adaptively adjust the asphalt injection speed according to the gap width.

[0043] In this embodiment, the guide assembly 14 includes a rotating groove 1401 formed on the side of the adjusting plate 12. A connecting block 1402 is fitted inside the rotating groove 1401. A first guide plate 1403 is fixedly connected above the connecting block 1402. A second guide plate 1404 and an extension plate 1405 are fixedly disposed on the first guide plate 1403. A movable groove 15 for sliding the extension plate 1405 is formed on the top of the outer casing 6. The second guide plate 1404 and the extension plate 1405 on the device can guide the flowing asphalt and prevent the asphalt from flowing out of the outside of the device. The rotating groove 1401 and the connecting block 1402 ensure that the rotation of the adjusting plate 12 will not affect the second guide plate 1404 and the extension plate 1405.

[0044] In this embodiment, the second guide plate 1404 is symmetrically distributed on the first guide plate 1403. The first guide plate 1403 is inclined. The sides of the second guide plate 1404 and the baffle 7 are in contact with each other. The connecting block 1402, the first guide plate 1403, the second guide plate 1404 and the extension plate 1405 are integrally formed to ensure the overall stability of the device. The in-place second guide plate 1404 and the baffle 7 ensure that the sides of the second guide plate 1404 remain sealed when it moves.

[0045] In this embodiment, the injection assembly 20 includes a fixing block 2001 fixedly installed at the bottom of the connecting plate 19. A ball bearing 2002 is rotatably installed on the fixing block 2001. A corrugated steel pipe 2003 is fixedly installed on the fixing block 2001. A heat insulation pipe 2005 is connected to the left side of the corrugated steel pipe 2003. The top of the heat insulation pipe 2005 is connected to the receiving box 21. The bottom of the corrugated steel pipe 2003 has an open structure. The corrugated steel pipe 2003 with an open structure at the bottom can fill the gaps with asphalt downwards. The corrugated steel pipe 2003 itself is expandable and expandable so as to adapt to gaps of different widths for subsequent road repair work.

[0046] In this embodiment, a spring 2004 is installed between the fixing block 2001 and the heat insulation pipe 2005. The spring 2004 is made of alloy steel to ensure that it has high-temperature resistance and to prevent significant changes in its elasticity due to high temperatures. The spring 2004 can tighten the heat insulation pipe 2005, allowing the device to fit gaps of different sizes for asphalt filling. Connecting blocks 2006 are installed at the bottom of both the fixing block 2001 and the heat insulation pipe 2005, and the connecting blocks 2006 have grooves. 2008, a slider 2007 is slidably installed in the groove 2008. The fixed block 2001 and the heat insulation pipe 2005 are fixedly connected to the slider 2007. The connecting block 2006 has a decreasing thickness from top to bottom. The connecting block 2006 can slide below the fixed block 2001 and the heat insulation pipe 2005 through the slider 2007 and the closed groove 2008. The connecting block 2006 with a decreasing thickness from top to bottom allows the device to abut against both sides of a narrow gap, thereby adapting to narrow cracks for asphalt grouting.

[0047] In this embodiment, the balls 2002 are evenly distributed on the fixed block 2001, and the balls 2002 protrude from the surface of the fixed block 2001. The evenly distributed balls 2002 ensure that the resistance is not too high when the device moves in the gap, thereby ensuring that the device can reduce the movement resistance while adapting to the gap trajectory.

[0048] It should be noted that this invention is a rapid repair device for asphalt pavement cracks. First, as follows... Figures 1-3 As shown, the entire device is supported by the support rod 2. Then, the fixing block 2001 and the heat insulation tube 2005 on the injection assembly 20 are pressed against both sides of the gap. The spring 2004 tightens the fixing block 2001 and the heat insulation tube 2005, so that the device adapts to the trajectory and width of the gap during movement. Figures 2-10As shown, the device injects heated asphalt into the housing 1. The asphalt flows through the connecting pipe 4 to the first guide plate 1403 and the second guide plate 1404 between two adjacent baffles 7. The first guide plate 1403 and the second guide plate 1404 form an inclined channel, allowing the asphalt to flow into the heat insulation pipe 2005 inside the injection assembly 20 through the inner groove 16 and opening 17 on the right side of the adjusting plate 12. The asphalt is then injected into the gaps through the opening at the bottom of the corrugated steel pipe 2003. During the asphalt injection process, the housing 1 is pushed, and the device moves forward as a whole through the casters 3. During the movement of the device, the sliding plate 23 under the sliding rod 24 slides downward and touches the ground, thereby realizing the function of automatic asphalt paving and avoiding asphalt overflow that would cause uneven road surface. The fixing rod 5 is used to connect the housing 1 and the outer shell 6 to ensure stable support for the device and facilitate subsequent cleaning of blockages. The connecting blocks 2006, whose thickness decreases from top to bottom, can abut against both sides of the road surface crack, thus enabling the device to adapt to narrower cracks for asphalt injection.

[0049] like Figures 2-10 As shown, when the device is working, the ball bearings 2002 on the fixed block 2001 can also be used to press against one side of the gap so that the resistance when the device moves is not too large. Under the action of the spring 2004, the heat insulation tube 2005 presses against the other side of the gap. The motor 9 drives the connecting shaft 10 and the partition 11 to rotate in the inner groove 16, so that the asphalt can be transported downward. When the partition 11 rotates, it can also drive the adjusting plate 12 to rotate. The adjusting plate 12 will rotate under the first guide plate 1403 through the rotating groove 1401 and the connecting block 1402. The receiving box 21 and the bottom plate 22 remain stationary. As the gap widens, the heat insulation pipe 2005 moves the receiving box 21 to the left. The protruding plate 18 blocks the right half of the receiving box 21, preventing the asphalt inside from flowing out. As the receiving box 21 moves to the left, the adjusting plate 12 slides outside the partition 11 and the adjusting plate 12 through the connecting groove 13, thereby increasing the effective space of the inner groove 16 and the opening 17. At the same time, the effective length of the partition 11 increases, thus automatically increasing the asphalt flow rate as the gap widens without changing the rotation of the motor 9. After the work is completed, the sliding plate 23 is pulled up and down, so that the sliding rod 24 on the sliding plate 23 can intermittently contact the ground and the protruding rod 27. At this time, the two adjacent sliding rods 24 can move towards each other, so that the device can remove the asphalt material on the two sliding rods 24 that are stuck together, preventing the two adjacent sliding rods 24 from sticking together.

[0050] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
