Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of auxiliary equipment for asphalt pavement construction, specifically, it relates to a repair device for asphalt pavement construction. Background Technology
[0002] During the construction of road engineering projects, after the asphalt concrete pavement is completed, quality defects such as uneven alignment, missing material, and rough surface often occur in local areas such as corner joints, manhole cover perimeter, etc., due to reasons such as insufficient paving process, insufficient compaction, or deviation in formwork installation.
[0003] To address these issues, specialized repair techniques are required. Current procedures include: first, using heating equipment to locally heat the defective area (such as recessed corners or pitted surfaces), raising the surface asphalt concrete temperature to 120-150℃. This softens the original material using thermal recycling technology. Then, the same type of hot-mix asphalt mixture is added, manually spread and leveled, with particular attention to adjusting the corner alignment to ensure a smooth transition with adjacent road surfaces. Finally, a small handheld vibratory compactor or a small double-drum roller is used for layered compaction, ensuring the compaction degree and porosity of the repaired area are within the design range. However, current asphalt pavement repair equipment only has single compaction or high-temperature heating functions, failing to achieve continuous supply and demand, resulting in low efficiency in the asphalt pavement repair process. Furthermore, the need to use multiple devices in an orderly manner for pavement repair makes the process complex and inconvenient to carry.
[0004] Based on this, the present invention provides a repair device for asphalt pavement construction to solve the problems existing in the prior art. Utility Model Content

[0026] As per the instruction manual Figures 1-7 As shown, this utility model provides a technical solution: A repair device for asphalt pavement construction includes a movable frame 1, and an asphalt heating mechanism, an asphalt trimming mechanism, and a layered compaction mechanism mounted on the frame 1; wherein: Each of the four corners of the bottom of the frame 1 is provided with a movable wheel 2, which is used to move the position of the frame 1 by means of the steering wheel 2; The asphalt heating mechanism is installed on the underside of the frame 1 and is used to heat the road asphalt during the movement of the frame 1. The asphalt trimming mechanism is installed on the proximal end and rear end push assembly of the frame 1 and is used to trim the asphalt road surface after it has been heated by the asphalt heating mechanism. The layered compaction mechanism is installed on the proximal end push assembly of the frame 1 and is located behind the asphalt trimming mechanism. It is used to compact the modified road asphalt in layers.
[0027] As described above, the pusher components facilitate the advancement of the vehicle frame 1 during operation, allowing it to move across the road surface for road finishing. The asphalt heating mechanism, asphalt finishing mechanism, and layered compaction mechanism can be assembled and installed as needed to form a complete asphalt road finishing structure. This structure heats, finishes, and compacts the asphalt in layers, effectively improving the efficiency of road finishing.
[0028] In a preferred embodiment, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the asphalt heating mechanism includes a liquefied petroleum gas (LPG) tank 9, a control box 10, and a heating plate 6. The LPG tank 9 is fixedly installed on the upper side of the vehicle frame 1 via a mounting bracket and connected to the control box 10 via a gas pipe, for supplying LPG for heating the heating plate 6. The control box 10 is used to control the ignition of the heating plate 6 and the gas flow rate of the gas pipe to the heating plate 6, thereby controlling the heating temperature of the heating plate 6. The heating plate 6 is fixedly installed on the lower side of the vehicle frame 1 for heating the asphalt layer of the road surface.
[0029] In the above description, the use of liquefied petroleum gas (LPG) tank 9 as the LPG source is simple and convenient, and easy to refill and replace after use, ensuring ease of use and replacement. The control box 10 is an automated control box equipped with an igniter (electronic igniter or piezoelectric ceramic ignition device) to control the ignition of the heating plate 6 and the gas flow from the gas pipe to the heating plate 6. Its principle is the same as that of a gas stove igniter, and is existing technology known to those skilled in the art, so it will not be described in detail here. The heating plate 6 is a structure of several interconnected heating plates with internal combustion chambers. During use, the control box 10 controls the mixed gas to enter the combustion chamber for ignition and combustion. After heat transfer through the heating plate 6, the gas heats the asphalt road surface. Its specific structure is existing technology known to those skilled in the art, so it will not be described in detail here.
[0030] In a preferred embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the pushing component includes a handrail 4 and an insert rod 5. The handrail 4 is rotatably mounted on the proximal end of the frame 1, and the insert rod 5 is movably inserted into the handrail 4. A handrail 7 is provided at the end of the insert rod 5 away from the handrail 4.
[0031] In the above description, the combination of the handrail 4, the insert rod 5, and the handrail 7 forms a complete pushing assembly, which facilitates workers to push the frame 1 on the road surface by holding the handrail 7 during on-site construction. It also allows for adjustment of the length and installation tilt of the pushing assembly according to on-site construction needs.
[0032] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the end of the handrail 4 furthest from the insertion rod 5 is also provided with a rotating shaft 20. The rotating shaft 20 is rotatably connected to the frame 1, and a clamping member 14 is fixedly sleeved on the rotating shaft 20. One end of the clamping member 14 abuts against the frame 1, and the other end is threadedly connected to the threaded sleeve 15. The end of the threaded sleeve 15 furthest from the clamping member 14 matches the frame 1. In use, the installation tilt of the handrail 4 is adjusted by rotating the rotating shaft 20 driven by the handrail 4. After the tilt is adjusted, the rotation of the threaded sleeve 15 is adjusted by the top block on the outside of the threaded sleeve 15, so that the threaded sleeve 15 abuts against the frame 1, thereby adjusting the installation tilt of the handrail 4.
[0033] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, both the insertion rod 5 and the support rod 4 have matching first positioning holes 22 on one side. Several first positioning holes 22 are provided on the support rod 4 and match the positioning bolts 23. In use, by adjusting the position of the support rod 4 on the insertion rod 5 and fixing it with the positioning bolts 23, the relative insertion depth of the insertion rod 5 and the support rod 4 can be adjusted, thus adjusting the length of the pushing component. This facilitates use by construction personnel under different working conditions.
[0034] In a preferred embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the asphalt trimming mechanism includes a connecting rod 8, which has a U-shaped structure. Several rake claws 3 are provided at the closed lower end of the connecting rod 8. These rake claws 3 are used to turn over the heated asphalt during use, facilitating further compaction. Each open upper end of the connecting rod 8 is provided with a locking post 24. The locking post 24 engages with a second limiting hole 21 on the surface of the insertion rod 5. During use, by engaging the locking post 24 with the second limiting hole 21 at different positions, the installation position of the asphalt trimming mechanism can be adjusted so that the depth to which the rake claws 3 are inserted into the asphalt meets the trimming requirements.
[0035] In the above description, the connection rod 8 and the locking post 24 are designed to facilitate the inclined installation of the rake claw 3 at the lower end of the insertion rod 5, so that it can turn over the asphalt inside during the back and forth movement of the frame 1, so as to facilitate the repeated rolling of the asphalt by the layered compaction mechanism, reduce the generation of voids and air holes in the asphalt layer, and ensure the compaction effect.
[0036] In a preferred embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the layered compaction mechanism ensures the vibration wheel 11 and the connecting frame 18. The vibration wheel 11 is located on the side of the connecting frame 18 near the road surface and is rotatably connected to the vibration wheel 11 via a steel ring belt 16. The other end of the connecting frame 18 is used in conjunction with the second guide groove 13 opened on the handrail 4 and the insert rod 5. A threaded rod 19 is also provided at the end of the connecting frame 18, which is used in conjunction with the first guide groove 12 opened on the handrail 4 and the insert rod 5. Threaded connectors 17 are also provided at both ends of the threaded rod 19 and are threadedly connected to the threaded rod 19. In use, the threaded rod 19 is fixedly installed at the connection between the handrail 4 and the insert rod 5 through the threaded connectors 17, so that the vibration wheel 11 can contact the asphalt ground and vibrate and compact the asphalt ground.
[0037] In the above description, the vibrating wheel 11 is composed of a vibrating steel wheel, an excitation mechanism, a shock absorption mechanism and a walking mechanism. Its specific structure is known to those skilled in the art and will not be described in detail here.
[0038] The implementation principle of the asphalt pavement repair device described in this embodiment is as follows: In practical use, the vehicle frame 1 is moved to the road surface area where the asphalt needs to be softened. Then, the liquefied gas tank 9 on top of the vehicle frame 1 heats the heating plate 6, and the asphalt trimming mechanism is installed according to the repair needs. After the heating plate 6 is heated, the asphalt in the road repair area is heated and softened. After softening, the asphalt surface layer is turned and trimmed using the asphalt trimming mechanism. Finally, the vibrating wheel 11 is used to vibrate and compact the asphalt road surface, thus achieving the repair of the highway road surface. During use, the horizontal and vertical processes can be adjusted according to the site requirements to achieve diversified use in the road repair process.
[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
