Abstract
Description
Technical Field
[0001] This application relates to the field of road asphalt technology, and in particular to a compaction device for asphalt roads. Background Technology
[0002] Asphalt is a dark brown, complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a high-viscosity organic liquid, in a liquid state, with a black surface, and is soluble in carbon disulfide. Asphalt is a waterproof, moisture-proof, and corrosion-resistant organic cementitious material. Asphalt can be mainly divided into three types: coal tar pitch, petroleum asphalt, and natural asphalt. Coal tar pitch is a by-product of coking, while petroleum asphalt is the residue after crude oil distillation. Asphalt is mixed with aggregates such as stones by heating and then laid on the upper part of the road base. The final step in road construction is to pave and compact the asphalt to form a complete road surface.
[0003] However, existing static asphalt compaction devices cannot adjust the compaction strength according to the characteristics of different asphalt materials and paving thickness, resulting in an inability to adjust the compaction effect. When paving thin layers, over-compaction is likely to cause aggregate breakage, while when paving thick layers, insufficient compaction may occur. Utility Model Content
[0004] The purpose of this application is to provide a compaction device for asphalt roads, which has the advantages of adapting to compaction operations on various different road surfaces. It solves the problem that existing static asphalt compaction devices cannot adjust the compaction strength according to the characteristics of different asphalt materials and paving thickness, resulting in an inability to adjust the compaction effect. In thin-layer paving, it is easy to over-compact and cause aggregate breakage, while in thick-layer paving, it may be under-compacted.
[0005] The technical solution of the asphalt road compaction device provided in this application is as follows: an asphalt road compaction device includes a roller body and a compaction drum. A support frame is fixedly connected to one side of the roller body. Fixed plates are fixedly connected to the bottom ends of both sides of the support frame. Two hydraulic rods arranged in a mirror distribution are fixedly connected to the upper ends of the two fixed plates. Lifting frames are fixedly connected to the telescopic ends of the four hydraulic rods in pairs. Mounting holes are opened inside the two lifting frames. Sliding grooves are opened on both sides of the support frame. Limiting grooves are opened on both sides inside the two sliding grooves. A support wheel is fixedly connected to the bottom end of the support frame. A rotating shaft is rotatably connected inside the compaction drum. Bushings are fixedly connected to both sides of the outside of the rotating shaft. Two limiting blocks arranged in a mirror distribution are fixedly connected to the outer walls of the two bushings. Baffles are fixedly connected to both ends of the rotating shaft.
[0006] By adopting the above technical solution, hydraulic rods are installed on the fixed plates at both ends of the support frame, and the telescopic ends of the hydraulic rods are connected to the lifting frame. The telescopic function of the hydraulic rods can drive the lifting frame to rise or fall. Since the compaction roller is connected to the lifting frame through structures such as rotating shafts and bushings, the height of the compaction roller can be adjusted. Construction personnel can control the contact degree between the compaction roller and the road surface according to the thickness of different asphalt pavements and specific compaction requirements to ensure the compaction effect. When the compaction device is not in working condition, the compaction roller can be raised off the ground by extending the four hydraulic rods. At this time, the ground is supported by the various support wheels, reducing the contact area with the ground, thereby reducing rolling resistance and reducing the overall power consumption of the equipment in the non-working state.
[0007] Preferably, two temperature monitors arranged in a mirror image are fixedly connected to one side of the bottom end of the support frame.
[0008] By adopting the above technical solution, two mirror-distributed temperature monitors can monitor the temperature of the asphalt pavement. The temperature monitors can feed back the pavement temperature information to the construction personnel. Through real-time monitoring, the construction personnel can understand the changes in pavement temperature in a timely manner and adjust parameters such as compaction speed and number of compaction passes according to the actual situation, thereby improving the compaction quality of the road.
[0009] Preferably, drive wheels are rotatably connected to both sides of the roller body.
[0010] By adopting the above technical solution, drive wheels are rotatably connected to both sides of the roller body to provide power to the device, ensuring its normal movement and compaction operation on the road and ensuring the stable operation of the device.
[0011] Preferably, a signal transmission module is fixedly connected to one side of the upper end of the road roller body, and a positioning module is fixedly connected to the end of the upper end of the road roller body away from the signal transmission module.
[0012] By adopting the above technical solutions, the signal transmission module can transmit various data of the road roller during operation to the construction management backend or the mobile terminal of relevant personnel in real time, realizing remote monitoring and command and dispatch. The positioning module can obtain the geographical location information of the road roller in real time, and obtain the number of compaction passes and range on the construction road surface.
[0013] Preferably, the two bushings are slidably disposed inside the sliding groove, and the four limiting blocks are all slidably disposed inside the limiting groove.
[0014] By adopting the above technical solution, the two bushings are slidably set inside the sliding groove, which provides the bushings with a movement trajectory, ensuring that the bushings can only move along a predetermined straight line. The four limit blocks are all slidably set inside the limit groove, and their shape and size match the limit groove to prevent the compaction roller from shifting laterally during operation.
[0015] Preferably, both bushings are fixedly disposed inside the mounting hole.
[0016] By adopting the above technical solution, two bushings are fixedly installed in the mounting holes inside the lifting frame. The compaction roller is connected to the lifting frame through bearings and bushings. Both lifting frames are lifted by two hydraulic rods, and the lifting and lowering of the hydraulic rods drives the lifting and lowering of the compaction roller.
[0017] Preferably, both baffles are located at the end of the bushing away from the compaction roller.
[0018] By adopting the above technical solution, the baffle is directly set at the end of the bushing away from the compaction roller, forming a barrier that can block the horizontal movement of the rotating shaft, thereby reducing the lateral movement of the compaction roller.
[0019] Preferably, the compaction roller is rotatably disposed inside the support frame, and the outer wall of the compaction roller is wavy.
[0020] By adopting the above technical solution, the outer wall of the wave-shaped compaction roller increases the contact area with asphalt during the rolling process, and applies downward pressure evenly to the asphalt surface, thereby improving compaction efficiency and enabling the asphalt pavement to achieve higher density in a shorter time.
[0021] In summary, this application includes at least one of the following beneficial technical effects:
[0022] This asphalt road compaction device uses hydraulic rods on both sides of the support frame to drive the lifting frame to rise and fall, adjusting the height of the compaction roller and thus the downward pressure to adapt to different asphalt thicknesses. A temperature monitor provides real-time feedback on asphalt pavement temperature changes, and a signal transmission module remotely transmits the data to the control center, allowing operators to adjust compaction parameters promptly. The corrugated roller design increases the contact area with the asphalt pavement, ensuring uniform pressure distribution, while the bushing limiting structure effectively prevents roller deviation. The positioning module records the construction trajectory, allowing for direct observation of the ground compaction status. This device, with its height-adjustable compaction mechanism, solves the problems of over-compaction or under-compaction caused by the non-adjustable pressure of traditional equipment, improving construction efficiency and quality. When the compaction device is not in operation, the compaction roller can be raised off the ground, with the two support wheels in contact with the ground, reducing rolling resistance and lowering power consumption during non-operation.

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail below.
[0032] Example 1: A compaction device for asphalt roads, referring to... Figure 1 , Figure 2 and Figure 3The system includes a roller body 1 and a compaction drum 10. A support frame 2 is fixedly connected to one side of the roller body 1. Fixed plates 3 are fixedly connected to the bottom ends of both sides of the support frame 2. Two hydraulic rods 4 arranged in a mirror image are fixedly connected to the upper ends of the two fixed plates 3. Lifting frames 5 are fixedly connected to the telescopic ends of the four hydraulic rods 4 in pairs. By setting hydraulic rods 4 on the fixed plates 3 at both ends of the support frame 2 and connecting the telescopic ends of the hydraulic rods 4 to the lifting frames 5, the lifting frames 5 can be raised or lowered by utilizing the telescopic function of the hydraulic rods 4. Mounting holes 6 are opened inside the two lifting frames 5. Sliding grooves 7 are opened on both sides of the support frame 2. Limit grooves 8 are opened on both sides of the two sliding grooves 7. Support wheels 9 are fixedly connected to the bottom end of the support frame 2. When the compaction device is not in working condition, the four hydraulic rods 4 The extension of the roller 10 allows it to be raised off the ground. The rollers 9 then support the ground, reducing the contact area and rolling resistance, thus lowering the overall power consumption when the equipment is not in operation. The roller 10 has a rotating shaft 11 internally connected to it. Bushings 12 are fixedly connected to both sides of the shaft 11. Two mirror-distributed limiting blocks 13 are fixedly connected to the outer walls of the two bushings 12. Baffles 14 are fixedly connected to both ends of the shaft 11. The roller 10 is connected to the lifting frame 5 via the shaft 11, bushings 12, and other structures, allowing for height adjustment. Construction personnel can control the contact degree between the roller 10 and the road surface according to the thickness of different asphalt pavements and specific compaction requirements, ensuring effective compaction.
[0033] Example 2: A compaction device for asphalt roads, referring to... Figure 4 , Figure 5 and Figure 6 Two temperature monitors 15, arranged in a mirror image, are fixedly connected to one side of the bottom of the support frame 2. These two mirror-image temperature monitors 15 can monitor the temperature of the asphalt pavement and provide feedback on the pavement temperature to the construction personnel. Through real-time monitoring, the construction personnel can promptly understand the changes in pavement temperature and adjust parameters such as compaction speed and number of compaction passes according to the actual situation to improve the compaction quality of the road. Drive wheels 16 are rotatably connected to both sides of the roller body 1, providing power to the device and ensuring its normal movement and compaction operation on the road, thus ensuring stable operation of the device. A signal transmission module 17 is fixedly connected to one side of the upper end of the roller body 1, and a positioning module 18 is fixedly connected to the end of the upper end of the roller body 1 away from the signal transmission module 17. The signal transmission module 17 can transmit various data of the roller during operation to the construction management backend or the mobile terminal of relevant personnel in real time, realizing remote monitoring and command and dispatch. The positioning module 18 can obtain the geographical location information of the roller in real time and obtain the number of compaction passes and range on the construction pavement.
[0034] Reference Figure 2 , Figure 3 and Figure 4 Two bushings 12 are slidably disposed inside the sliding groove 7, and four limiting blocks 13 are slidably disposed inside the limiting groove 8. The sliding groove 7 provides a movement trajectory for the bushings 12, ensuring that the bushings 12 can only move along a predetermined straight line. The four limiting blocks 13 are slidably disposed inside the limiting groove 8, and their shape and size match the limiting groove 8 to prevent the compaction roller 10 from shifting laterally during operation. Two bushings 12 are fixedly disposed inside the mounting holes 6. The compaction roller 10 is connected to the lifting frame 5 through bearings and bushings 12. The two lifting frames 5 are connected to the lifting frame 5 through two hydraulic... The hydraulic rod 4 is lifted, and the lifting and lowering of the hydraulic rod 4 drives the lifting and lowering of the compaction roller. Both baffles 14 are set at the end of the bushing 12 away from the compaction roller 10. The baffles 14 are directly set at the end of the bushing 12 away from the compaction roller 10, forming a block that can block the horizontal movement of the rotating shaft 11, thereby reducing the lateral movement of the compaction roller 10. The compaction roller 10 is rotatably set inside the support frame 2. The outer wall of the compaction roller 10 is wavy. The undulating compaction roller 10 outer wall increases the contact area with the asphalt during rolling, and applies downward pressure evenly to the asphalt surface, thereby improving the compaction efficiency and enabling the asphalt pavement to achieve a higher density in a shorter time.
[0035] The implementation principle of this application embodiment is as follows:
[0036] During movement, the roller body 1 moves to the work area via drive wheels 16. During operation, the hydraulic rods 4 on both sides of the support frame 2 retract, causing the lifting frame 5 to descend, bringing the compaction roller 10 into contact with the ground. The contact force between the compaction roller 10 and the road surface is adjusted by regulating the extension and retraction of the hydraulic rods 4 according to construction needs, adapting to the compaction requirements of different asphalt pavements. The compaction roller 10 is connected to the lifting frame 5 via a rotating shaft 11 and a bushing 12. The bushing 12 slides within the sliding groove 7 of the support frame 2. The limiting block 13 cooperates with the limiting groove 8 to reduce lateral displacement of the compaction roller 10, ensuring compaction stability. The baffle 14 further restricts the horizontal movement of the rotating shaft 11, enhancing overall compaction stability. The compaction roller 10 has a stable structure and a wavy outer wall, which increases the contact area with the asphalt during rolling, and applies downward pressure evenly to the road surface, improving the compaction efficiency and density of the asphalt pavement. During operation, the temperature monitor 15 monitors the road surface temperature in real time, and the data is fed back to the background through the signal transmission module 17, which facilitates the construction personnel to adjust the compaction parameters. The positioning module 18 can obtain the equipment position information, record the number of compaction passes and the range, and ensure the quality of road construction. When the compaction operation is completed and the device is not in working condition, the hydraulic rod 4 extends to drive the compaction roller 10 to rise, and the support wheel 9 at the bottom of the support frame 2 contacts the ground, reducing rolling resistance and reducing power consumption during movement.
