Description

Technical Field

[0001] This application relates to the field of highway repair technology, and in particular to a device for repairing and treating cracks in municipal highways. Background Technology

[0002] As the core framework of urban transportation networks, municipal roads bear the burden of massive daily vehicle traffic. However, during their long-term service, various cracks and defects inevitably appear. On the one hand, the repeated crushing and impact of vehicle loads, especially the high-frequency passage of heavy-duty trucks, causes fatigue stress in the pavement structure, gradually leading to problems such as alligator cracking and longitudinal cracks. On the other hand, the significant thermal expansion and contraction effect caused by seasonal temperature differences—high summer temperatures cause pavement materials to expand, while low winter temperatures cause them to contract—can easily lead to transverse cracks over a long period. In addition, uneven settlement of the subgrade soil, improper material ratios or insufficient compaction during construction, as well as natural factors such as rainwater erosion and freeze-thaw damage, can all accelerate the initiation and expansion of cracks. If these cracks are not treated in time, they will not only affect driving comfort and safety but also allow rainwater and snowmelt to seep into the pavement base and subgrade, causing more serious defects such as base softening and subgrade hollowing, significantly shortening the service life of the road. Therefore, after cracks appear on the road, it is necessary to use municipal road crack repair and treatment equipment to repair the cracks to ensure the road can be used normally.

[0003] When using the municipal highway crack repair device, raw materials such as asphalt modified slurry or polymer slurry are mixed in proportion to ensure that the slurry has good fluidity and adhesion. The slurry is then accurately pushed along the delivery pipeline to the grouting gun head and injected into the highway crack. After the slurry is injected into the crack, it fills the gap and undergoes a physicochemical reaction with the original pavement material. After curing, it forms a high-strength, high-adhesion repair body, effectively restoring the structural integrity and load-bearing capacity of the pavement.

[0004] In existing municipal highway crack repair devices, during actual construction, dust from passing vehicles, road surface debris, and environmental impurities such as mud and sand continuously accumulate in the cracks. These impurities adhere evenly to the crack surface. When grout is injected into the dusty cracks, the dust acts as a "separation layer" between the grout and the crack wall. On the one hand, dust particles hinder direct contact between the grout and the road surface substrate, reducing the adhesion between the grout and the road surface. On the other hand, the tiny pores in the dust trap air, forming bubbles and reducing the density of the repair, thus affecting the quality of the repair. Summary of the Invention

[0005] The purpose of this application is to provide a municipal highway crack repair and treatment device to address the problem mentioned in the background art that dust in highway cracks can reduce the adhesion between the grout and the road surface.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution: A municipal highway crack repair device includes a support plate, with support legs fixed at each of the four lower corners of the support plate. Casters are installed at the lower ends of the support legs. A storage tank is fixed at the upper end of the support plate, and a heating sleeve is provided outside the storage tank. A cover plate is fixed at the upper end of the storage tank, and a mixing motor and a feed pipe are fixed at the upper end of the cover plate. A handle is fixed at the upper end of the support plate, and a controller is fixed to the side of the support plate. The controller is electrically connected to the mixing motor. A grouting structure for repairing highway cracks is provided between the support plate and the storage tank. A cleaning structure for cleaning highway cracks is provided at the lower end of the support plate.

[0007] When repairing road cracks, push the handle to move the device to the crack. Then, clean the crack using the cleaning structure. After cleaning, push the device so that the grouting structure corresponds to the crack. Grout is then injected into the crack using the grouting structure. After grouting, it is manually smoothed, thus repairing the road crack. The cleaning structure effectively cleans the road crack, making repair easier.

[0008] Furthermore, the cleaning structure includes a collection box installed at the lower end of the support plate, a sealing side plate fixed to the side of the collection box, a guide pipe fixed to the upper end of the collection box, a collection cover fixed to the end of the guide pipe away from the collection box, an air outlet at the bottom of the collection box, a collection frame fixed inside the collection box, a collection net fixed inside the collection frame, a negative pressure component inside the collection box, a cleaning component inside the collection cover, and an adjustment component between the collection box and the support plate.

[0009] By adopting the above technical solution, the cleaning structure can remove gravel and dust from the road cracks, reducing the amount of gravel and dust in the cracks, which is more conducive to subsequent crack repair and thus improves the repair quality.

[0010] Furthermore, the negative pressure assembly includes a drive motor fixed to the side of the collection box, the controller is electrically connected to the drive motor, the output end of the drive motor extends out of the collection box and is rotatably connected to the collection box, the output end of the drive motor is fixed with a drive shaft, and an impeller is fixed on the drive shaft.

[0011] By adopting the above technical solution, the negative pressure component is used to generate negative pressure inside the collection box, and then the collection cover is generated under the action of the guide pipe, thereby playing the role of collecting debris and dust.

[0012] Furthermore, the cleaning assembly includes a mounting shaft rotatably connected inside the collection hood, on which a cleaning brush is fixed.

[0013] By adopting the above technical solution, the cleaning component can clean the crack, thereby improving the cleaning effect of debris and dust inside the crack, making the crack cleaner and thus improving the repair quality.

[0014] Furthermore, a drive shaft is fixed to the side of the collection cover, a drive gear is fixed on the drive shaft, one end of the mounting shaft extends out of the collection cover, and a driven gear that meshes with the drive gear is fixed thereon.

[0015] By adopting the above technical solution, when the transmission shaft rotates, the mounting shaft rotates under the action of the driving gear and the driven gear.

[0016] Furthermore, the end of the drive shaft away from the drive motor extends out of the collection box and is fixed with a first pulley, while a second pulley is fixed on the transmission shaft, and the first pulley and the second pulley are connected by a transmission belt.

[0017] By adopting the above technical solution, when the drive shaft rotates, the first pulley, the transmission belt, and the second pulley cause the transmission shaft to rotate, thereby achieving the transmission function.

[0018] Furthermore, the adjustment assembly includes an adjustment plate installed at the lower end of the support plate, a connecting plate fixed at the upper end of both the collection box and the collection cover, the connecting plate being fixedly connected to the adjustment plate, a hydraulic telescopic rod fixed at the upper end of the support plate, the controller being electrically connected to the hydraulic telescopic rod, and the telescopic end of the hydraulic telescopic rod slidingly penetrating the support plate and being fixedly connected to the adjustment plate.

[0019] By adopting the above technical solution, the height of the sweeping brush can be adjusted by adjusting the components, so that the sweeping brush can clean cracks of different depths. When cleaning road cracks, the height of the sweeping brush can be adjusted according to the crack depth, thereby improving the applicability.

[0020] Furthermore, a guide post is fixed to the lower end of the support plate, and the guide post slides through the adjustment plate.

[0021] By adopting the above technical solution, the guide column plays the role of guiding and further supporting the adjustment plate, so that the adjustment plate can move more smoothly.

[0022] Furthermore, the grouting structure includes a pump fixed to the upper end of the support plate, the inlet end of the pump extending into the storage tank, a delivery pipe fixed to the outlet end of the pump, a corrugated hose fixed to the end of the delivery pipe away from the pump, a grouting gun fixed to the end of the corrugated hose away from the delivery pipe, and an electric telescopic rod fixed to the lower end of the support plate, the telescopic end of the electric telescopic rod being fixedly connected to the grouting gun.

[0023] By adopting the above technical solution, when grouting the crack, the electric telescopic rod drives the grouting gun to move downward, so that the grouting gun head corresponds to the crack. Then, the pump draws out the grout from the storage tank and injects it into the road crack through the grouting gun, thereby realizing the grouting of the crack.

[0024] In summary, this application includes at least one of the following beneficial effects; 1. In this application, when cleaning road cracks, the handle is pushed to move the device to the crack, so that the position of the collection hood corresponds to the road crack. Then, the drive motor is turned on by the controller, so that the drive shaft rotates and drives the impeller to rotate. The rotation of the impeller creates a negative pressure inside the collection box. Then, under the action of the guide pipe, a negative pressure is created at the position of the collection hood. Under the action of the negative pressure, gravel, dust and other debris at the crack are sucked into the collection hood and then enter the collection box through the guide pipe. Finally, they fall into the collection net inside the collection frame, thus cleaning the crack. By sweeping away the gravel at the crack, the amount of gravel and dust at the crack is reduced. After the grout is injected, the grout can better adhere to the road surface, thereby improving the repair quality of road cracks.

[0025] 2. In this application, when the drive shaft drives the impeller to rotate, the first pulley, the transmission belt, and the second pulley cause the drive shaft to drive the drive gear to rotate. Then, under the action of the driven gear, the mounting shaft rotates, which in turn drives the sweeping brush to rotate. The rotating sweeping brush can sweep the road cracks, allowing the gravel, dust, and other debris in the cracks to be separated from the cracks more quickly and enter the collection hood more quickly, thereby improving the cleaning efficiency and eliminating the need for repeated cleaning.

[0026] 3. In this application, the rotating cleaning brush can sweep away some strongly adhering debris, separating the strongly adhering debris from the cracks, thereby improving the cleaning effect of highway cracks and making it more conducive to the repair of highway cracks.

[0027] 4. The hydraulic telescopic rod is activated by the controller, causing it to extend or retract, thereby adjusting the height of the adjusting plate. This adjustment allows for the adjustment of the sweeping brush height, enabling the brush to clean cracks of varying depths and improving its applicability. Attached Figure Description

[0030] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0031] This application discloses a device for repairing cracks in municipal highways.

[0032] Reference Figures 1-3A municipal highway crack repair and treatment device includes a support plate 1, with support legs 11 fixed at the four corners of the lower end of the support plate 1. Universal wheels are installed at the lower ends of the support legs 11. A storage tank 12 is fixed at the upper end of the support plate 1. A heating sleeve is provided outside the storage tank 12. A cover plate 13 is fixed at the upper end of the storage tank 12. A mixing motor 14 and a feed pipe 15 are fixed at the upper end of the cover plate 13. A handle 16 is fixed at the upper end of the support plate 1. A controller 17 is fixed on the side of the support plate 1. The controller 17 is electrically connected to the mixing motor 14. A grouting structure for repairing highway cracks is provided between the support plate 1 and the storage tank 12. A cleaning structure for cleaning highway cracks is provided at the lower end of the support plate 1.

[0033] The grouting structure includes a pump 2 fixed to the upper end of the support plate 1. The inlet end of the pump 2 extends into the storage tank 12. A delivery pipe 21 is fixed to the outlet end of the pump 2. A corrugated hose 22 is fixed to the end of the delivery pipe 21 away from the pump 2. A grouting gun 23 is fixed to the end of the corrugated hose 22 away from the delivery pipe 21. An electric telescopic rod 24 is fixed to the lower end of the support plate 1. The telescopic end of the electric telescopic rod 24 is fixedly connected to the grouting gun 23.

[0034] When repairing road cracks, push handle 16 to move the device to the crack. Then, clean the road crack using a cleaning structure. After cleaning, push the device so that the nozzle of the grouting gun 23 corresponds to the crack. Then, activate the electric telescopic rod 24 via controller 17, causing the telescopic end of the electric telescopic rod 24 to extend. The extension of the telescopic end of the electric telescopic rod 24 moves the grouting gun 23 downward, bringing the nozzle of the grouting gun 23 closer to the crack. Then, activate the extraction pump 2 via controller 17 to extract the grout from the storage tank 12. The grout is then delivered to the grouting gun 23 through the delivery pipe 21 and the corrugated hose 22, and finally flows out from the nozzle and is injected into the crack until the crack is filled. Finally, it is smoothed manually to achieve road repair.

[0035] Reference Figures 4-6 The cleaning structure includes a collection box 3 installed at the lower end of the support plate 1, a sealing side plate 31 fixed to the side of the collection box 3, a guide pipe 33 fixed to the upper end of the collection box 3, a collection cover 34 fixed to the end of the guide pipe 33 away from the collection box 3, an air outlet 32 ​​opened at the bottom of the collection box 3, a collection frame 35 fixed inside the collection box 3, a collection net 36 fixed inside the collection frame 35, a negative pressure component inside the collection box 3, a cleaning component inside the collection cover 34, and an adjustment component between the collection box 3 and the support plate 1.

[0036] The negative pressure component includes a drive motor 37 fixed to the side of the collection box 3. The controller 17 is electrically connected to the drive motor 37. The output end of the drive motor 37 extends out of the collection box 3 and is rotatably connected to the collection box 3. The output end of the drive motor 37 is fixed with a drive shaft 371, and an impeller 372 is fixed on the drive shaft 371.

[0037] When cleaning the cracks in the road, the drive motor 37 is turned on by the controller 17. When the drive motor 37 is working, it drives the drive shaft 371 to rotate. The rotation of the drive shaft 371 drives the impeller 372 to rotate. The rotation of the impeller 372 creates a negative pressure inside the collection box 3. Then, under the action of the guide pipe 33, a negative pressure is created at the position of the collection cover 34. Under the action of the negative pressure, the gravel, dust and other debris in the crack are sucked into the collection cover 34, and then enter the collection box 3 through the guide pipe 33. Finally, they fall onto the collection net 36 inside the collection frame 35, thus cleaning the crack. By sweeping away the gravel in the crack, the amount of gravel and dust in the crack is reduced. After the grout is injected, the grout can better adhere to the road surface, thereby improving the repair quality of the road crack.

[0038] Reference Figures 5-7 The cleaning assembly includes a mounting shaft 38 rotatably connected inside the collection cover 34, and a cleaning brush 381 is fixed on the mounting shaft 38.

[0039] The collection cover 34 has a drive shaft 382 fixed on its side, a drive gear 383 fixed on the drive shaft 382, ​​and one end of the mounting shaft 38 extends out of the collection cover 34 and is fixed with a driven gear 384 that meshes with the drive gear 383.

[0040] In addition, the end of the drive shaft 371 away from the drive motor 37 extends out of the collection box 3 and is fixed with a first pulley 385. A second pulley 386 is fixed on the transmission shaft 382. The first pulley 385 and the second pulley 386 are connected by a transmission belt 387.

[0041] When the drive shaft 371 drives the impeller 372 to rotate, the first pulley 385 at its end rotates accordingly. The rotation of the first pulley 385, under the action of the transmission belt 387, causes the second pulley 386 to rotate. The rotation of the second pulley 386 causes the drive shaft 382 to drive the drive gear 383 to rotate. The rotation of the drive gear 383 drives the driven gear 384 to rotate, causing the mounting shaft 38 to rotate. The rotation of the mounting shaft 38 drives the cleaning brush 381 to rotate. The rotating cleaning brush 381 can clean the road cracks, allowing gravel, dust, and other debris in the cracks to separate more quickly and enter the collection hood 34 more rapidly, thus improving cleaning efficiency and eliminating the need for repeated cleaning. Furthermore, the rotating cleaning brush 381 can sweep away some strongly adhered debris, separating it from the cracks, thereby improving the cleaning effect of road cracks and facilitating their repair.

[0042] Reference Figure 2 and Figure 4 The adjustment assembly includes an adjustment plate 39 installed at the lower end of the support plate 1, a connecting plate 391 fixed at the upper end of the collection box 3 and the collection cover 34, the connecting plate 391 being fixedly connected to the adjustment plate 39, a hydraulic telescopic rod 392 fixed at the upper end of the support plate 1, the controller 17 being electrically connected to the hydraulic telescopic rod 392, the telescopic end of the hydraulic telescopic rod 392 slidingly penetrating the support plate 1 and being fixedly connected to the adjustment plate 39.

[0043] Among them, a guide post 393 is fixed at the lower end of the support plate 1, and the guide post 393 slides through the adjustment plate 39.

[0044] Before use, the hydraulic telescopic rod 392 is activated by the controller 17, causing the hydraulic telescopic rod 392 to work and extend or retract its telescopic end, thereby adjusting the height of the adjusting plate 39. By adjusting the height of the adjusting plate 39, the height of the sweeping brush 381 can be adjusted, enabling the sweeping brush 381 to clean cracks of different depths and improve its applicability.

[0045] Working principle: When repairing road cracks, push handle 16 to move the device to the crack, so that the position of collection cover 34 corresponds to the road crack. Then, adjust the height of sweeping brush 381 according to the depth of the crack. During adjustment, the controller 17 controls the opening of hydraulic telescopic rod 392, so that the hydraulic telescopic rod 392 works, and its telescopic end extends or retracts, thereby adjusting the height of adjustment plate 39. By adjusting the height of adjustment plate 39, the height of sweeping brush 381 can be adjusted, so that sweeping brush 381 can clean cracks of different depths. Then, the drive motor 37 is turned on by the controller 17 to make it work. When the drive motor 37 is working, it drives the drive shaft 371 to rotate. The rotation of the drive shaft 371 drives the impeller 372 to rotate. The rotation of the impeller 372 creates a negative pressure inside the collection box 3. Then, under the action of the guide pipe 33, a negative pressure is created at the position of the collection cover 34. Under the action of the negative pressure, the gravel, dust and other debris in the crack are sucked into the collection cover 34 and then enter the collection box 3 through the guide pipe 33. Finally, they fall onto the collection net 36 inside the collection frame 35, thus cleaning the crack. By sweeping the gravel in the crack, the amount of gravel and dust in the crack is reduced. After the slurry is injected, the slurry can better adhere to the road surface, thereby improving the repair quality of the road crack. When the drive shaft 371 drives the impeller 372 to rotate, the first pulley 385 at its end rotates accordingly. As the first pulley 385 rotates, the second pulley 386 rotates under the action of the transmission belt 387. The rotation of the second pulley 386 causes the drive shaft 382 to drive the drive gear 383 to rotate. The drive gear 383 then drives the driven gear 384 to rotate, causing the mounting shaft 38 to rotate. The rotation of the mounting shaft 38 drives the cleaning brush 381 to rotate. The rotating cleaning brush 381 can clean the road cracks, allowing debris such as gravel and dust to be separated from the cracks more quickly and enter the collection hood 34 more rapidly, thus improving cleaning efficiency and eliminating the need for repeated cleaning. Furthermore, the rotating cleaning brush 381 can sweep away some strongly adhering debris, separating it from the cracks, thereby improving the cleaning effect of the road cracks and making them more suitable for repair. After cleaning, the device is pushed so that the nozzle of the grouting gun 23 corresponds to the crack. Then, the electric telescopic rod 24 is activated by the controller 17, causing the telescopic end of the electric telescopic rod 24 to extend. The extension of the telescopic end of the electric telescopic rod 24 drives the grouting gun 23 to move down, so that the nozzle of the grouting gun 23 is close to the crack. Then, the extraction pump 2 is activated by the controller 17, and the grout inside the storage tank 12 is extracted by the extraction pump 2. It is then sent to the grouting gun 23 through the delivery pipe 21 and the corrugated hose 22. Finally, it flows out from the nozzle and is injected into the crack until the crack is filled. Finally, it is smoothed manually to achieve road repair.
