Description

Technical Field

[0001] This application relates to the field of asphalt pavement repair technology, and in particular to an asphalt pavement crack filling device. Background Technology

[0002] Asphalt pavement, as an important component of modern transportation infrastructure, is widely used due to its good comfort and skid resistance. In actual use, asphalt pavement is exposed to a complex environment for a long time, and is subjected to multiple effects such as temperature changes, vehicle loads, and rainwater erosion, which causes cracks to appear in the asphalt pavement. In order to reduce the problem of water seeping into the base layer through the cracks and accelerating pavement damage, it is necessary to repair the cracks in a timely manner.

[0003] When repairing cracks in asphalt pavement, the crack area must first be thoroughly cleaned using tools such as high-pressure blowers and milling machines to remove dust, gravel, and loose materials, thus preventing impurities from affecting the repair effect. After cleaning, the crack area is precisely heated using an infrared heating machine to soften the asphalt pavement and enhance the adhesion between the new and old materials. If the crack is wide or deep, specialized grouting equipment is required to inject hot asphalt into the crack. Finally, compaction equipment (such as small road rollers and vibratory rammers) is used to repeatedly compact the repair area, ensuring that the new filling material is tightly bonded to the original pavement, restoring the pavement's smoothness and load-bearing capacity.

[0004] The current repair method, which relies on the coordinated operation of multiple devices, has problems in actual construction. Because different equipment is needed for the heating, grouting, and compaction processes, the construction team has to frequently move and adjust the equipment. This not only consumes a lot of time and manpower, but also easily leads to inconsistent repair quality and low efficiency due to improper equipment connection.

[0005] Asphalt pavements are prone to cracking during use due to factors such as temperature changes and vehicle loads. If cracks are not repaired in time, moisture will seep into the base layer, accelerating pavement damage. Therefore, cracks in asphalt pavements should be repaired promptly.

[0006] During repair, the crack area needs to be cleaned first. After cleaning, the crack area is heated using an infrared heating machine. If grouting is required after heating, the grouting equipment is moved to the crack area for grouting. After grouting is completed, the compaction equipment is moved to the crack area for compaction to complete the road repair.

[0007] The above methods require the use of multiple devices working together and frequent switching of different devices, resulting in low overall repair efficiency. Utility Model Content

[0008] The purpose of this application is to provide an asphalt pavement crack filling device to solve the problem that in actual construction, the construction team has to frequently move and adjust the equipment because different equipment is required for the heating, grouting and compaction processes.

[0009] To achieve the above objectives, this application specifically adopts the following technical solution: An asphalt pavement crack filling device includes a base plate, with casters installed at all four corners of the lower end of the base plate. A handrail is fixed to the upper end of the base plate, and a liquefied gas tank and a burner are fixed to the upper end of the base plate. An infrared heating plate is fixed to the lower end of the base plate. A controller is provided on the side of the burner, and a power supply is installed inside the controller. A pressure gauge and an alarm are installed on the controller. The controller is electrically connected to the burner. A grouting structure is provided at the upper end of the base plate, and a compaction structure is provided on the side of the base plate near the handrail.

[0010] By adopting the above technical solution, when in use, the device is pushed to the crack in the road surface that needs repair, so that the infrared heating plate is above the crack. Then, the road surface at the crack is heated by the infrared heating plate. After heating, depending on the road surface condition, if grouting is not required, the device is pushed to compact and level the road surface using the compaction structure. If grouting is required, grouting is performed through the grouting structure. After grouting, compaction and leveling are performed again. This device integrates infrared heating, grouting, and compaction, and is convenient to use and operate with high efficiency.

[0011] Furthermore, the grouting structure includes an asphalt heating and storage tank fixed to the upper end of the base plate, a cover plate installed on the upper end of the asphalt heating and storage tank, a pump fixed on the asphalt heating and storage tank, a delivery pipe fixed to the end of the pump away from the asphalt heating and storage tank, a grouting gun fixed to the end of the delivery pipe away from the pump, two symmetrically arranged fixing springs fixed on the asphalt heating and storage tank, a heat equalization component installed inside the asphalt heating and storage tank, a control panel fixed to the side of the handrail, and the control panel electrically connected to the pump.

[0012] By adopting the above technical solution, when grouting is required, the user holds the grouting gun and inserts the end of the grouting gun into the road surface crack, then turns on the extraction pump to achieve grouting.

[0013] Furthermore, the heat equalization assembly includes a drive motor fixed to the upper end of the cover plate. The drive motor is electrically connected to the control panel. The output end of the drive motor is rotatably connected to the cover plate and extends into the interior of the asphalt heating storage tank. A drive shaft is fixed to the output end of the drive motor, and an agitator blade is fixed on the drive shaft.

[0014] By adopting the above technical solution, the heat equalization component can agitate the asphalt inside the asphalt heating storage tank, thereby making the asphalt heating more uniform.

[0015] Furthermore, a connecting rod is fixed on the drive shaft, and a vertical rod is fixed to the end of the connecting rod away from the drive shaft. A scraper strip is fixed to the side of the vertical rod away from the connecting rod. The scraper strip is a high-temperature resistant rubber strip and is in contact with the inner wall of the asphalt heating storage tank.

[0016] By adopting the above technical solution, the drive shaft drives the connecting rod to rotate, thereby driving the upright and scraping strip to rotate, which can reduce the impact of asphalt adhering to the inner wall of the asphalt heating storage tank on heat transfer.

[0017] Furthermore, the lower end of the cover plate is rotatably connected to two symmetrically arranged stirring shafts, and a second stirring blade is fixed on the stirring shaft. The first stirring blade and the second stirring blade are arranged alternately.

[0018] By adopting the above technical solution, the stirring shaft drives the stirring blades to rotate, which can further improve the mixing of asphalt inside the asphalt heating storage tank, making the heating more uniform.

[0019] Furthermore, a drive gear is fixed on the drive shaft, and a driven gear that meshes with the drive gear is fixed on the agitator shaft. The diameter of the drive gear is larger than the diameter of the driven gear.

[0020] By adopting the above technical solution, the rotation of the drive shaft drives the rotation of the active gear, which in turn causes the driven gear to rotate, thereby causing the agitator shaft to rotate and driving the transmission.

[0021] Furthermore, an installation strip is fixed to the lower end of the drive shaft, and a scraper strip is fixed to the lower end of the installation strip. The scraper strip is attached to the bottom of the asphalt heating storage tank, and the scraper strip is a high-temperature resistant rubber strip.

[0022] By adopting the above technical solution, the drive shaft drives the installation strip and scraper strip to rotate, which can scrape the material attached to the bottom of the asphalt heating storage tank and reduce the sedimentation at the bottom.

[0023] Furthermore, the compaction structure includes a mounting plate fixed to the side of the base plate near the handrail frame. There are two mounting plates arranged symmetrically, and a mounting shaft rotates between the two mounting plates. A compaction roller is fixed on the mounting shaft.

[0024] By adopting the above technical solution, when it is necessary to compact the asphalt pavement, the handrail is pushed to move the entire device to the area that needs to be compacted, so that the compaction rollers reciprocate over the area that needs to be compacted, thereby compacting and smoothing the asphalt pavement and improving the repair quality.

[0025] In summary, this application includes at least one of the following beneficial effects: 1. In this application, the device is moved above the road surface crack and heated using an infrared heating device. If grouting is required after heating, it is done using a grouting structure. Finally, the device is pushed to compact and level the surface using a compaction structure. This device integrates heating, grouting, and compaction into one unit, eliminating the need for frequent transfers and replacements of equipment, thereby improving repair quality and efficiency.

[0026] 2. In this application, the heat equalization component can uniformly mix the asphalt inside the asphalt heating storage tank, thereby enabling uniform heating of the asphalt, which is more conducive to subsequent crack grouting. It can also scrape off the asphalt adhering to the inner wall of the asphalt heating storage tank, reducing the problem of asphalt crusting under heating, which affects heat conduction and causes uneven heating of the asphalt, thus making the asphalt heating more uniform.

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] This application discloses an asphalt pavement crack filling device.

[0031] Reference Figure 1 and Figure 2An asphalt pavement crack filling device includes a base plate 1, with casters 11 installed at the four corners of the lower end of the base plate 1, a handrail 12 fixed to the upper end of the base plate 1, a liquefied gas tank 13 and a burner 14 fixed to the upper end of the base plate 1, an infrared heating plate 15 fixed to the lower end of the base plate 1, a controller 16 installed on the side of the burner 14, a power supply installed inside the controller 16, a pressure gauge and an alarm installed on the controller 16, and the controller 16 is electrically connected to the burner 14. A grouting structure 2 is installed at the upper end of the base plate 1, and a compaction structure 3 is installed on the side of the base plate 1 near the handrail 12.

[0032] When repairing road cracks using this road crack filling device, the operator first cleans the crack area, then pushes the handrail 12 to move the entire device. When the infrared heating plate 15 moves above the crack, it stops moving, and the controller 16 turns on the burner 14, allowing the combustion gas inside the liquefied gas tank 13 to enter the burner 14 for combustion. During combustion, heat energy is generated, which heats the radiation tube inside the infrared heating plate 15, stimulating infrared radiation to heat the road surface. After heating, if the crack is large, grouting is performed on the crack through the grouting structure 2. After grouting, the device is pushed to compact and level the road surface using the compaction structure 3, completing the road crack repair. This device integrates road heating, grouting, and compaction, making it convenient to use and improving repair efficiency.

[0033] Reference Figure 2 and Figure 4 The grouting structure 2 includes an asphalt heating and storage tank 21 fixed to the upper end of the base plate 1. A cover plate 22 is installed on the upper end of the asphalt heating and storage tank 21. A pump 23 is fixed on the asphalt heating and storage tank 21. A delivery pipe 24 is fixed to the end of the pump 23 away from the asphalt heating and storage tank 21. A grouting gun 25 is fixed to the end of the delivery pipe 24 away from the pump 23. Two symmetrically arranged fixing springs 211 are fixed on the asphalt heating and storage tank 21. A heat equalization component 4 is installed inside the asphalt heating and storage tank 21. A control panel 5 is fixed to the side of the handrail frame 12. The control panel 5 is electrically connected to the pump 23.

[0034] After heating the road surface cracks, if grouting is required, the delivery pipe 24 is removed, separating it from the fixing spring 211. The user then holds the grouting gun 25, inserting its end into the crack. The extraction pump 23 is then activated via the control panel 5 to extract asphalt from the asphalt heating storage tank 21. The user then controls the grouting gun 25 to grout the road surface cracks. After grouting, the extraction pump 23 is turned off, and the delivery pipe 24 is then secured to the two fixing springs 211. The grouting structure 2 enables grouting of road surface cracks without the need for other grouting equipment, thus improving work efficiency.

[0035] Reference Figure 4 The heat equalization component 4 includes a drive motor 41 fixed on the upper end of the cover plate 22. The drive motor 41 is electrically connected to the control panel 5. The output end of the drive motor 41 is rotatably connected to the cover plate 22 and extends into the interior of the asphalt heating storage tank 21. The output end of the drive motor 41 is fixed with a drive shaft 42, and an agitator blade 421 is fixed on the drive shaft 42.

[0036] Among them, a connecting rod 43 is fixed on the drive shaft 42, and a vertical rod 431 is fixed to the end of the connecting rod 43 away from the drive shaft 42. A scraper strip 432 is fixed to the side of the vertical rod 431 away from the connecting rod 43. The scraper strip 432 is a high-temperature resistant rubber strip and is in contact with the inner wall of the asphalt heating storage tank 21.

[0037] During use, the drive motor 41 is turned on via the control panel 5. The drive motor 41 drives the drive shaft 42 to rotate, which in turn drives the agitator blade 421 to rotate, thereby fully mixing the asphalt inside the asphalt heating storage tank 21 and ensuring uniform heating. At the same time, the drive shaft 42 drives the connecting rod 43 to rotate, causing the upright rod 431 and the scraper blade 432 to rotate as well. When the scraper blade 432 rotates, it can scrape off the asphalt adhering to the inside of the asphalt heating storage tank 21, thereby reducing the problem of asphalt crusting on the inner wall of the asphalt heating storage tank 21 during heating, which affects heat conduction and causes uneven asphalt heating. This makes the asphalt heating more uniform and is more conducive to subsequent grouting operations.

[0038] Reference Figure 4 The lower end of the cover plate 22 is rotatably connected to two symmetrically arranged stirring shafts 44. A second stirring blade 441 is fixed on the stirring shaft 44, and the first stirring blade 421 and the second stirring blade 441 are arranged alternately.

[0039] Among them, a drive gear 45 is fixed on the drive shaft 42, and a driven gear 451 that meshes with the drive gear 45 is fixed on the agitator shaft 44. The diameter of the drive gear 45 is larger than the diameter of the driven gear 451.

[0040] When the drive shaft 42 rotates, it drives the drive gear 45 to rotate. When the drive gear 45 rotates, it drives the driven gear 451 to rotate, which causes the agitator shaft 44 to rotate and drives the agitator blade 441 to rotate. Since the diameter of the drive gear 45 is larger than the diameter of the driven gear 451, the rotation speed of the agitator shaft 44 is greater than that of the drive shaft 42. Through the differential rotation of the drive shaft 42 and the agitator shaft 44, the asphalt inside the asphalt heating storage tank 21 can be mixed more thoroughly and heated more evenly.

[0041] Reference Figure 4The lower end of the drive shaft 42 is fixed with an installation strip 46, and the lower end of the installation strip 46 is fixed with a scraper strip 461. The scraper strip 461 is attached to the bottom of the asphalt heating storage tank 21. The scraper strip 461 is a high-temperature resistant rubber strip.

[0042] When the drive shaft 42 rotates, it drives the mounting strip 46 at its lower end to rotate as well. At this time, the scraper strip 461 rotates as well. The rotation of the scraper strip 461 can scrape up the material attached to the bottom of the asphalt heating storage tank 21, thereby reducing the sedimentation at the bottom and further improving the mixing and heat uniformity of the asphalt.

[0043] Reference Figure 1 and Figure 2 The compaction structure 3 includes a mounting plate 31 fixed on the side of the base plate 1 near the handrail 12. There are two mounting plates 31 arranged symmetrically. A mounting shaft rotates between the two mounting plates 31, and a compaction roller 32 is fixed on the mounting shaft.

[0044] When the road surface needs to be compacted and leveled, push the handrail frame 12 to move the entire device. When the device moves, the compaction roller 32 rotates. When the compaction roller 32 comes into contact with the asphalt road surface to be compacted and leveled, the asphalt road surface can be compacted and leveled using the compaction roller 32 without the need for an additional leveling device, thus improving the efficiency of road repair.

[0045] Working principle: When using this road crack filling device to repair road cracks, the operator first cleans the crack area, then pushes the handrail 12 to move the entire device. When the infrared heating plate 15 moves above the crack, it stops moving and the controller 16 turns on the burner 14, allowing the combustion gas inside the liquefied tank 13 to enter the burner 14 for combustion. During combustion, heat energy is generated, which heats the radiation tube inside the infrared heating plate 15, stimulating infrared radiation to heat the road surface. After heating is complete, the mobile device exposes the crack. If the crack is large, the delivery pipe 24 is removed, separating it from the fixing spring 211. The user then holds the grouting gun 25 and inserts the end of the grouting gun 25 into the crack. The user then turns on the extraction pump 23 via the control panel 5, causing the extraction pump 23 to extract the asphalt from the asphalt heating storage tank 21. The user then controls the grouting gun 25 to grout the road crack. After grouting is completed, the extraction pump 23 is turned off, and the delivery pipe 24 is then clipped into the two fixing springs 211. After grouting is completed, push the handrail frame 12 to move the entire device. When the device moves, the compaction roller 32 rotates. When the compaction roller 32 comes into contact with the asphalt pavement to be compacted and leveled, the compaction roller 32 can be used to compact and level the asphalt pavement. If the crack is small and does not require grouting, the device can be directly pushed to compact and level the pavement at the crack.
