Description

Technical Field

[0001] The present invention relates to the field of compaction equipment, specifically a pavement base compaction equipment with an intelligent compaction system and a compaction degree detection device. Background Art

[0002] During road construction, the compaction quality of the roadbed and pavement is one of the most important internal indicators in the construction quality management of road and bridge projects. Only by fully compacting the roadbed and pavement structural layers can the strength, stiffness, stability, and flatness of the roadbed and pavement be ensured, thereby extending the service life of highway bridges. When using the prior art for extrusion pouring of the road surface, it is necessary to prepare and stir the pouring material in advance, then clean the road surface where the pouring material needs to be laid, and then use a transportation device to transport the pouring material to the road surface for spreading. After spreading, the spread pouring material is leveled, and then a road roller is used to compact the pouring material, so that the basic construction of the road surface can be completed. However, in the prior art, after compacting the road surface, fixed-point compaction degree detection is still carried out on the road surface. The existing compaction degree detection methods require continuous operation on the same road surface, and the compaction equipment is constantly moving during work, making it necessary to manually detect the compaction situation of the road surface at fixed points subsequently, which is extremely inconvenient. Summary of the Invention

[0003] The present invention provides a pavement base compaction equipment with an intelligent compaction system and a compaction degree detection device, which overcomes the deficiencies described in the background art.

[0004] The technical solution adopted by the present invention to solve its technical problems is as follows: A compaction degree detection device, including a detection part for being installed at the bottom of the compactor body. The detection part includes a buffer device and an adaptive detection component installed on the lower side of the buffer device. The adaptive detection component includes symmetrically arranged motors, linear rails, and a detection device body. A lead screw is arranged in each linear rail, and the two lead screws are respectively installed on the output shafts of the two motors. The two ends of the detection device body are respectively installed on the linear rails through a lead screw slider, and the two lead screws respectively penetrate through the lead screw slider to drive the detection device body to slide through the motors; When the compactor body moves, the motors drive the detection device body to slide in the opposite direction of the movement of the compactor body, and the sliding speed of the detection device body is the same as the movement speed of the compactor body; The detection device body includes a fixing plate, an electromagnetic wave compaction detector, a first electric push rod, and a second electric push rod. The electromagnetic wave compaction detector is connected to the screw sliders on both sides through the fixing plate. The first electric push rod is installed at the lower end of the electromagnetic wave compaction detector. An anti-interference insertion tube is installed on the output shaft of the first electric push rod. The second electric push rod is installed inside the anti-interference insertion tube, and a detection head signal-connected to the electromagnetic wave compaction detector is provided on the output shaft of the second electric push rod, so as to detect the compaction degree of the road surface below through the detection head.

[0005] In a preferred technical solution, the anti-interference insertion tube includes a support rod, a cover plate, and a sleeve. The cover plate is connected to the output shaft of the first electric push rod. The sleeve is installed at the lower end of the cover plate through the support rod. There is a cavity for accommodating the second electric push rod between the cover plate and the sleeve, and the anti-interference insertion tube is hollow. The detection head is arranged in the middle of the anti-interference insertion tube and is installed on the output shaft of the second electric push rod to drive the detection head to lift through the second electric push rod; The distance between the anti-interference insertion tube and the ground is fixed. When the detection head does not detect the compaction degree of the road surface below, the detection head is placed inside the anti-interference insertion tube. When the detection head detects the compaction degree of the road surface below, the first electric push rod pushes the anti-interference insertion tube downward, so that the sleeve is inserted into the ground, and the detection head is retracted upward through the second electric push rod, and the retraction distance of the detection head is equal to the distance that the first electric push rod pushes the anti-interference insertion tube downward.

[0006] In a preferred technical solution, the buffer device includes a plate body, C-shaped connecting ribs, and air bags. The C-shaped connecting ribs are arranged in an array on the lower side of the plate body. An air bag is installed in each C-shaped connecting rib. All the air bags are made into negative pressure by an air compressor to adjust the expansion size. One side of the C-shaped connecting rib is an open structure, and one side of the air bag extends to the opening of the C-shaped connecting rib. When the air compressor creates positive pressure to inflate the air bag, the surface of the air bag near the opening of the C-shaped connecting rib expands outward; Convex portions protruding outward are provided at the upper and lower ends of the surface of the C-shaped connecting rib near its opening. The two convex portions are staggered, and the corresponding part of the air bag and the upper convex portion is recessed inward; Both the motor and the end of the linear guide away from the motor are fixed to the plate body through the respective adjacent C-shaped connecting ribs.

[0007] In a preferred technical solution, a buffer connecting rib is provided on the side of the C-shaped connecting rib away from the air bag. The surface of the buffer connecting rib near the C-shaped connecting rib is inclined. The buffer connecting rib and the C-shaped connecting rib are connected by a telescopic rod. When the C-shaped connecting rib is tilted by force, the telescopic rod is squeezed to contract, and the buffer connecting rib is deformed by force; A limiting plate is provided on each of the left and right sides of the C-shaped connecting rib, and the air bag is arranged between the two limiting plates.

[0008] A preferred technical solution of the buffer device further includes a buffer plate, which is arranged between the C-shaped connecting rib and the buffer connecting rib, and the buffer plate corresponds to and abuts against the convex part on the lower side of the surface of the C-shaped connecting rib. The middle part of the buffer plate is curved. When the C-shaped connecting rib is forced to swing inwards, the C-shaped connecting rib presses the buffer plate.

[0009] The roadbed compaction equipment with an intelligent compaction system includes the compaction degree detection device described above, including a compactor body and a material bin, a material discharge device, and a detection part installed on the compactor body. The material bin is filled with fillers for laying on the road surface. The material discharge device is communicated with the side of the material bin to extract the fillers in the material bin to the road surface for discharge through the material discharge device. It includes a compactor body and a material bin, a material discharge device, and a detection part installed on the compactor body. The material bin is filled with fillers for laying on the road surface. The material discharge device is communicated with the side of the material bin to extract the fillers in the material bin to the road surface for discharge through the material discharge device. The detection part is located between the wheels arranged on the lower side of the compactor body. A roller housing is arranged at the end of the compactor body, and a compaction roller is arranged in the roller housing. The material discharge device includes a spiral material lifting pipe and a discharge pipe. The discharge pipe is fixed to the upper end of the roller housing, and the end of the discharge pipe is arranged obliquely and protrudes from the side of the roller housing to convey the fillers to the discharge pipe through the spiral material lifting pipe and discharge the fillers, and compact the fillers through the compaction roller.

[0010] Compared with the prior art, this technical solution has the following advantages: In the present invention, driven by the motor, the detection device body can move in a direction opposite to that of the compactor body, and the speed matches the moving speed of the compactor. This design enables the detection device body to always maintain a relative static state with the road surface during the movement of the compactor. In other words, the detection device body can continuously detect the road surface at the same position at the moment when the compactor moves. This setting of the relatively static detection position ensures that the detection head can obtain the compaction degree data at the same position multiple times and stably, thereby improving the accuracy and reliability of the detection results.

[0011] When conducting compaction degree detection, the electric push rod 1 pushes the anti-interference insertion tube downward, causing the sleeve to insert into the ground. At the same time, the electric push rod 2 retracts the detection head upward by a distance equal to the distance that the anti-interference insertion tube inserts into the ground. This design ensures that the detection head can stably contact the road surface, avoiding poor contact caused by uneven or soft road surfaces. In this way, the detection head can conduct compaction degree detection at the optimal position, further improving the accuracy and reliability of the detection. In addition, the design of the anti-interference insertion tube also significantly enhances the adaptability of the detection device to complex construction environments. Road construction environments often have interference factors such as dust, moisture, chemical corrosion, and mechanical vibration, and the anti-interference insertion tube can effectively shield these interferences, ensuring that the detection head can work stably in various harsh environments. For example, in a humid or chemically corrosive environment, the sleeve and cover plate can prevent moisture and chemical substances from entering the interior of the detection head, thereby protecting the detection head from damage.

Detailed implementation mode

[0023] As Figures 1 to 7 shown, a compaction degree detection device is proposed in the present invention, including a detection unit 4 for being installed at the bottom of the body 1 of the compactor, the detection unit 4 includes a buffer device 41 and an adaptive detection component 42 installed on the lower side of the buffer device 41. The adaptive detection component 42 includes symmetrically arranged motors 421, linear guides 422, and a detection device body 423. A lead screw is arranged in each linear guide 422, and the two lead screws are respectively installed on the output shafts of the two motors 421. The two ends of the detection device body 423 are respectively installed on the linear guides 422 through a lead screw slider, and the two lead screws respectively pass through the lead screw slider to drive the detection device body 423 to slide through the motor 421. When the body 1 of the compactor moves, the motor 421 drives the detection device body 423 to slide in the opposite direction of the movement of the body 1 of the compactor, and the sliding speed of the detection device body 423 is the same as the movement speed of the body 1 of the compactor. The detection device body 423 includes a fixing plate 4231, an electromagnetic wave compaction degree detector 4232, an electric push rod 1 4233, and an electric push rod 2 4234. The electromagnetic wave compaction degree detector 4232 is connected to the lead screw sliders on both sides through the fixing plate 4231. The electric push rod 1 4233 is installed at the lower end of the electromagnetic wave compaction degree detector 4232. An anti-interference insertion tube 2331 is installed on the output shaft of the electric push rod 1 4233, and the electric push rod 2 4234 is installed in the anti-interference insertion tube 2331. A detection head 2321 signal-connected to the electromagnetic wave compaction degree detector 4232 is arranged on the output shaft of the electric push rod 2 4234 to detect the compaction degree of the road surface below through the detection head 2321. In the present invention, when the body 1 of the compactor moves, the motor 421 drives the detection device body 423 to slide in the direction opposite to the movement direction of the compactor body, and the sliding speed of the detection device body is the same as the movement speed of the compactor body. The core purpose of this design is to ensure that the detection device body 423 can always maintain the same position to detect the compaction degree of the road surface during the movement of the compactor, so as to achieve continuous and real-time compaction degree monitoring. Driven by the motor 421, the detection device body 423 can move in the direction opposite to the compactor body 1, and the speed matches the movement speed of the compactor. This design enables the detection device body to always maintain a relative static state with the road surface during the movement of the compactor. In other words, the detection device body 423 can continuously detect the road surface at the same position at the moment when the compactor moves. This setting of the relatively static detection position ensures that the detection head 2321 can obtain the compaction degree data of the same position multiple times and stably, thereby improving the accuracy and reliability of the detection results.

[0024] Traditional compaction degree detection methods require fixed-point detection after the compaction operation is completed, which not only increases the complexity of the construction process but also may lead to problems such as untimely and incomplete detection. The design of the present invention enables the compaction degree detection to be carried out synchronously with the compaction operation without additional detection procedures. This synchronous detection method greatly improves the construction efficiency, reduces the construction time, and also avoids the rework problem caused by untimely detection. For example, during the movement of the compactor, the detection device body 423 can detect the compaction degree in real time and transmit the data to the control system. The construction personnel can adjust the compaction parameters according to the real-time data to ensure that the compaction quality meets the requirements, thereby accelerating the construction progress. Moreover, the present invention uses an electromagnetic wave compaction degree detector 4232 for compaction degree detection, which belongs to a non-destructive detection method. This method can not only reduce the damage to the road surface but also improve the detection efficiency and the construction quality control level. Compared with traditional destructive detection methods, the non-destructive detection method does not require sampling or damaging the road surface, can be detected repeatedly, has a fast detection speed, is not affected by the weather, and is suitable for real-time monitoring at the construction site. The combination of this non-destructive detection method and the synchronous reverse movement of the detection device body 423 further improves the accuracy and reliability of the detection.

[0025] Moreover, the first electric push rod 4233 is installed at the lower end of the electromagnetic wave compaction degree detector 4232. Its main function is to adjust the height of the detection device body 423 in the vertical direction. Through the telescopic movement of the first electric push rod, the distance between the detection device body and the road surface can be adjusted in real time according to the unevenness of the road surface, ensuring that the detection head 2321 can stably contact the road surface. This height adjustment ability enables the detection device to maintain a stable detection effect under complex road conditions and avoid poor contact or damage between the detection head and the road surface caused by road surface undulations.

[0026] Furthermore, the anti-interference insertion tube 2331 includes a support rod, a cover plate, and a sleeve. The cover plate is connected to the output shaft of the first electric push rod 4233. The sleeve is installed at the lower end of the cover plate through the support rod. There is a cavity for accommodating the second electric push rod 4234 between the cover plate and the sleeve. And the anti-interference insertion tube 2331 is hollow. The detection head 2321 is arranged in the middle of the anti-interference insertion tube 2331, and the detection head 2321 is installed on the output shaft of the second electric push rod 4234 to drive the detection head 2321 to move up and down through the second electric push rod 4234. The distance between the anti-interference insertion tube 2331 and the ground is fixed. When the detection head 2321 does not detect the compaction degree of the road surface below it, the detection head 2321 is placed inside the anti-interference insertion tube 2331. When the detection head 2321 detects the compaction degree of the road surface below it, the first electric push rod 4233 pushes the anti-interference insertion tube 2331 downward, inserts the sleeve into the ground, and retracts the detection head 2321 upward through the second electric push rod 4234. And the retraction distance of the detection head 2321 is equal to the downward push distance of the first electric push rod 4233 for the anti-interference insertion tube 2331. In the present invention, not only the functions of the detection device are optimized, but also the accuracy and reliability of the compaction degree detection are significantly improved. The main function of the anti-interference insertion tube 2331 is to provide a stable detection environment for the detection head 2321 and prevent the influence of external interference on the detection results. When the detection head is not working, the detection head is stored inside the anti-interference insertion tube, avoiding interference from factors such as dust, moisture, chemical corrosion, and mechanical vibration.

[0027] This protection mechanism not only extends the service life of the detection head, but also reduces the detection errors caused by external interference, ensuring the accuracy and reliability of the detection data. When performing the compaction degree detection, the electric push rod 1-4233 pushes the anti-interference insertion tube 2331 downward, causing the sleeve to insert into the ground. At the same time, the electric push rod 2-4234 contracts the detection head 2321 upward, and the contraction distance is equal to the distance that the anti-interference insertion tube inserts into the ground. This design ensures that the detection head can stably contact the road surface, avoiding poor contact caused by uneven or soft road surfaces. In this way, the detection head can perform the compaction degree detection at the optimal position, further improving the accuracy and reliability of the detection. In addition, the design of the anti-interference insertion tube 2331 also significantly improves the adaptability of the detection device to complex construction environments. Road construction environments often have interference factors such as dust, moisture, chemical corrosion, and mechanical vibration, and the anti-interference insertion tube can effectively shield these interferences, ensuring that the detection head can work stably in various harsh environments. For example, in a humid or chemically corrosive environment, the sleeve and the cover plate can prevent moisture and chemical substances from entering the inside of the detection head, thus protecting the detection head from damage.

[0028] Moreover, the buffer device 41 includes a plate body 411, C-shaped connecting ribs 412, and air bags 413. The C-shaped connecting ribs 412 are arrayed on the lower side of the plate body 411, and an air bag 413 is installed in each C-shaped connecting rib 412. All the air bags 413 are manufactured into negative pressure by an air compressor to adjust the expansion size. One side of the C-shaped connecting rib 412 is an open structure, and one side of the air bag 413 extends to the opening of the C-shaped connecting rib 412. When the air compressor manufactures positive pressure to inflate the air bag 413, the surface of the air bag 413 close to the opening of the C-shaped connecting rib 412 expands outward. This design enables the buffer device to adaptively adjust the buffer strength according to the unevenness of the road surface and the moving speed of the compactor, thereby maintaining the stability of the detection device in a complex construction environment. Wherein, convex portions protruding outward are provided at the upper and lower ends of the surface of the C-shaped connecting rib 412 close to its opening, and the two convex portions are staggered. And the corresponding position of the air bag 413 and the upper convex portion is recessed inward. Both the motor 421 and the end of the linear guide 422 far from the motor 421 are fixed to the plate body 411 through the adjacent C-shaped connecting ribs 412. As can be seen from the above, through the dynamic buffering function of the airbag 413, the device can effectively absorb the vibration and impact force generated by the compactor on uneven roads or complex construction environments. This buffering mechanism not only reduces the shaking of the detection device, but also significantly improves the stability of the detection process, ensuring that the detection head 2321 can perform compaction detection in a stable environment. Secondly, the expansion and contraction of the airbag can be adjusted by the air compressor. This adaptive ability enables the buffer device to flexibly adjust the buffering strength according to different road conditions and construction requirements. On rugged roads, the airbag can be filled with more gas to provide a stronger buffering effect; on flat roads, the airbag can be properly deflated to reduce unnecessary buffering, thereby achieving precise dynamic adjustment and further improving the detection accuracy. In addition, the design of the buffer device significantly enhances the durability of the detection device. The synergistic effect of the airbag and the C-shaped connecting rib 412 can effectively disperse the impact force, protect the detection device from damage caused by strong impact, extend the service life of the equipment, and reduce the maintenance cost and replacement frequency of the equipment. Through this design, the detection device can maintain high-precision and high-stability detection capabilities even in complex construction environments, significantly reducing detection errors caused by vibration or impact, and ensuring the accuracy and reliability of compaction detection data; Furthermore, the buffering effect described above can be changed accordingly through artificial adjustment, which can effectively improve the adaptability of the equipment.

[0029] Furthermore, a buffer connecting rib 414 is provided on the side of the C-shaped connecting rib 412 away from the airbag 413, and the surface of the buffer connecting rib 414 near the C-shaped connecting rib 412 is inclined. The buffer connecting rib 414 is connected to the C-shaped connecting rib 412 by a telescopic rod 415. When the C-shaped connecting rib 412 is tilted by force, the telescopic rod 415 is squeezed to shrink, and the buffer connecting rib 414 is deformed by force; a limit plate 4121 is provided on the left and right sides of the C-shaped connecting rib 412, and the airbag 413 is arranged between the two limit plates 4121. When the C-shaped connecting rib 412 is subjected to external force such as impact caused by uneven road surface, its force-bearing end will tilt inward. At this time, the buffer connecting rib 414 connected to the C-shaped connecting rib contacts the C-shaped connecting rib through the inclined surface, which plays a preliminary buffering role. Since the surface of the buffer connecting rib is inclined, this design can effectively disperse external force and avoid concentrated impact from causing damage to the device. When the C-shaped connecting rib is tilted by force, the telescopic rod will be squeezed and contracted to further absorb the external force. This design allows the telescopic rod 415 to undergo axial compression deformation during the shock absorption process, converting the external force into elastic potential energy, thereby effectively reducing the transmission of the impact force.

[0030] Moreover, when the C-shaped connecting rib is stressed and swings, the airbag 413 will be squeezed. Since the airbag is filled with gas inside, it will undergo elastic expansion and contraction deformation when stressed. The presence of the limit plate 4121 can limit the excessive deformation of the airbag, ensure that the airbag can evenly disperse the impact force when stressed, and at the same time prevent the airbag from being damaged due to excessive local stress.

[0031] Moreover, the buffer device 41 further includes a buffer plate 416. The buffer plate 416 is arranged between the C-shaped connecting rib 412 and the buffer connecting rib 414, and the buffer plate 416 corresponds to and abuts against the protruding part on the lower side of the surface of the C-shaped connecting rib 412; the middle part of the buffer plate 416 is curved. When the C-shaped connecting rib 412 is stressed and swings inward, the C-shaped connecting rib 412 squeezes the buffer plate 416. This design endows the buffer plate with good elastic properties. When the C-shaped connecting rib 412 is stressed and swings inward, the protruding part on its lower side will squeeze the buffer plate 416, causing the buffer plate to undergo elastic bending deformation. The bending deformation of the buffer plate can further absorb the impact energy and reduce the influence of external forces on the detection device. This deformation process is similar to the compression and recovery of a spring, which can effectively relieve the instantaneous impact force and ensure the stability of the detection device in a dynamic environment.

[0032] Moreover, the present invention also proposes a pavement base compaction device with an intelligent compaction system. The pavement base compaction device includes a compactor body 1 and a material bin 2, a material discharging device 3, and a detection part 4 installed on the compactor body 1. The material bin 2 is filled with fillers for laying on the road surface. The material discharging device 3 is communicated with the side of the material bin 2 to extract the fillers in the material bin 2 to the road surface for discharging through the material discharging device 3; The detection part 4 is located between the wheels 11 arranged on the lower side of the compactor body 1. The end of the compactor body 1 is provided with a roller housing 12. A compaction roller 13 is arranged in the roller housing 12. The material discharging device 3 includes a spiral material lifting pipe 31 and a discharge pipe 32. The discharge pipe 32 is fixed to the upper end of the roller housing 12. The end of the discharge pipe 32 is arranged in an inclined shape and protrudes from the side of the roller housing 12 to convey the fillers to the discharge pipe 32 through the spiral material lifting pipe 31 and discharge the fillers, and compact the fillers through the compaction roller 13. This inclined design enables the fillers to be discharged at a specific angle and speed, ensuring that the fillers are evenly laid on the road surface. At the same time, the inclined end helps to reduce the accumulation and blockage of materials during the discharging process and improves the discharging efficiency.

[0033] The above is only a preferred embodiment of the present invention, and thus the scope of implementation of the present invention cannot be limited thereby. That is, equivalent changes and modifications made according to the scope of the present invention patent and the content of the specification should still fall within the scope covered by the present invention.
