Description

Technical Field

[0001] The present invention relates to the field of compaction equipment, in particular to road 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 of the quality management of road and bridge construction. Only by fully compacting the roadbed and pavement structure layers can the strength, stiffness, stability and flatness of the roadbed and pavement be guaranteed, thereby extending the service life of highway bridges. When using existing technology to extrude and pour the pavement, it is necessary to configure and mix the pouring materials in advance, and then clean the pavement where the pouring materials are to be laid. Then, the pouring materials can be transported to the pavement for spreading using transportation equipment. After spreading, the spread pouring materials are evenly spread, and then compacted using a roller. In this way, the basic construction of the road pavement can be completed. However, in the existing technology, after compacting the pavement, the pavement will also be tested for compaction at a fixed point. The existing compaction test method requires continuous operation on the same pavement, and the compaction equipment is constantly moving forward during work, which requires subsequent manual fixed-point testing of the pavement compaction condition, which is too inconvenient. Summary of the Invention

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

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] The compaction degree detection device includes a detection portion for installation at the bottom of the compactor body, the detection portion including a buffer device and an adaptive detection assembly installed on the lower side of the buffer device, the adaptive detection assembly including symmetrically arranged motors and linear rails, and a detection device body, each linear rail is provided with a screw, the two screws are respectively installed on the output shafts of the two motors, and both ends of the detection device body are respectively installed on the linear rails via screw sliders, and the two screws respectively pass through the screw sliders to drive the detection device body to slide via the motor;

[0006] When the compactor body moves, the motor drives 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 moving speed of the compactor body;

[0007] The detection device body includes a fixed plate, an electromagnetic wave compaction detector, an electric push rod 1 and an electric push rod 2. The electromagnetic wave compaction detector is connected to the screw sliders on both sides through the fixed plate. The electric push rod 1 is installed at the lower end of the electromagnetic wave compaction detector. An anti-interference plug is installed on the output shaft of the electric push rod 1, and the electric push rod 2 is installed in the anti-interference plug. A detection head connected to the signal of the electromagnetic wave compaction detector is provided on the output shaft of the electric push rod 2 to perform compaction detection on the road surface below it through the detection head.

[0008] A preferred technical solution, the anti-interference cannula 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 cannula is hollow, the detection head is arranged in the middle of the anti-interference cannula, and the detection head is installed on the output shaft of the second electric push rod, so that the detection head can be driven to rise and fall by the second electric push rod;

[0009] The distance between the anti-interference cannula and the ground is fixed. When the detection head is not detecting the compaction of the road surface below it, the detection head is placed in the anti-interference cannula. When the detection head is detecting the compaction of the road surface below it, the electric push rod 1 pushes the anti-interference cannula downward to insert the sleeve into the ground, and the detection head is retracted upward by the electric push rod 2, and the distance the detection head is retracted is equal to the distance the electric push rod 1 pushes the anti-interference cannula downward.

[0010] A preferred technical solution is that the buffer device includes a plate body, a C-shaped connecting rib, and an airbag. The C-shaped connecting ribs are arrayed on the lower side of the plate body, and an airbag is installed in each C-shaped connecting rib. All airbags adjust their expansion size by creating negative pressure through an air compressor mechanism. One side of the C-shaped connecting rib is an open structure, and one side of the airbag extends to the opening of the C-shaped connecting rib. When the air compressor creates positive pressure to inflate the airbag, the surface of the airbag near the opening of the C-shaped connecting rib expands outward.

[0011] The surface of the C-shaped connecting rib is provided with outwardly protruding protrusions at the upper and lower ends near the opening thereof, the two protrusions are staggered, and the airbag and the corresponding portion of the upper protrusion are recessed inward;

[0012] The motor and the end of the linear rail away from the motor are fixed to the plate body through adjacent C-shaped connecting ribs.

[0013] A preferred technical solution is provided with a buffer connecting rib on the side of the C-shaped connecting rib away from the airbag. The surface of the buffer connecting rib near the C-shaped connecting rib is inclined. The buffer connecting rib is connected to the C-shaped connecting rib by a telescopic rod. When the C-shaped connecting rib is tilted by force, the telescopic rod is squeezed and contracted, and the buffer connecting rib is deformed by force.

[0014] A limiting plate is respectively provided on the left and right sides of the C-shaped connecting rib, and the airbag is arranged between the two limiting plates.

[0015] 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 the raised portion on the lower side of the surface of the C-shaped connecting rib and abuts against the raised portion on the lower side;

[0016] The middle portion of the buffer plate is curved, and when the C-shaped connecting ribs are forced to swing inwards, the C-shaped connecting ribs squeeze the buffer plate.

[0017] A road base compacting device with an intelligent compaction system includes the compaction degree detection device, a compactor body, a material bin mounted on the compactor body, a material discharge device, and a detection unit. The material bin is filled with a filler for laying on the road surface. The material discharge device is connected to the side of the material bin so that the filler in the material bin is extracted and discharged onto the road surface through the material discharge device.

[0018] The compactor comprises a compactor body, a material bin mounted on the compactor body, a material discharge device, and a detection unit. The material bin is filled with a filler for paving on a road surface. The material discharge device is connected to a side of the material bin so as to extract the filler in the material bin and discharge it onto the road surface.

[0019] The detection part is located between the wheels arranged on the lower side of the compactor body. A roller shell is provided at the end of the compactor body, and a compacting roller is provided in the roller shell. 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 shell. The end of the discharge pipe is arranged in an inclined shape and protrudes from the side of the roller shell to transport the filler to the discharge pipe through the spiral material lifting pipe and discharge the filler, and compact the filler through the compacting roller.

[0020] Compared with the existing technology, this technical solution has the following advantages:

[0021] In this invention, the detection device, driven by a motor, can move in a direction opposite to the compactor body, at a speed that matches the compactor's movement. This design allows the detection device to remain stationary relative to the road surface during the compactor's movement. In other words, the detection device can continuously monitor the same road surface location while the compactor is moving. This relatively stationary detection position ensures that the detection head can repeatedly and stably obtain compaction data from the same location, thereby improving the accuracy and reliability of the test results.

[0022] When performing a compaction test, electric push rod 1 pushes the anti-interference cannula downward, inserting the sleeve into the ground. Simultaneously, electric push rod 2 retracts the detection head upward, a distance equal to the distance the anti-interference cannula is inserted into the ground. This design ensures that the detection head can maintain stable contact with the road surface, avoiding poor contact caused by uneven or soft road surfaces. In this way, the detection head can perform compaction tests at the optimal position, further improving the accuracy and reliability of the test. In addition, the design of the anti-interference cannula significantly enhances the detection device's adaptability to complex construction environments. Road construction environments are often subject to interference factors such as dust, moisture, chemical corrosion, and mechanical vibration. The anti-interference cannula can effectively shield these interferences, ensuring that the detection head can operate stably in a variety of harsh environments. For example, in humid or chemically corrosive environments, the sleeve and cover prevent moisture and chemicals from entering the detection head, thereby protecting the detection head from damage.

DETAILED DESCRIPTION

[0037] like Figures 1 to 7 As shown, the present invention proposes a compaction detection device, including a detection part 4 for installation at the bottom of the compactor body 1, the detection part 4 includes a buffer device 41, and an adaptive detection assembly 42 installed on the lower side of the buffer device 41, the adaptive detection assembly 42 includes a symmetrically arranged motor 421 and a linear rail 422, and a detection device body 423, each linear rail 422 is provided with a screw, and the two screws are respectively installed on the output shafts of the two motors 421, and both ends of the detection device body 423 are respectively installed on the linear rail 422 through a screw slider, and the two screws respectively pass through the screw slider to drive the detection device body 423 to slide through the motor 421;

[0038] When the compactor body 1 moves, the motor 421 drives the detection device body 423 to slide in the opposite direction of the movement of the compactor body 1, and the sliding speed of the detection device body 423 is the same as the moving speed of the compactor body 1;

[0039] The detection device body 423 includes a fixed plate 4231, an electromagnetic wave compaction detector 4232, an electric push rod 1 4233, and an electric push rod 2 4234. The electromagnetic wave compaction detector 4232 is connected to the screw sliders on both sides through the fixed plate 4231. The electric push rod 1 4233 is installed at the lower end of the electromagnetic wave compaction detector 4232. The output shaft of the electric push rod 1 4233 is installed with an anti-interference cannula 2331, and the electric push rod 2 4234 is installed in the anti-interference cannula 2331. The output shaft of the electric push rod 2 4234 is provided with a detection head 2321 connected to the signal of the electromagnetic wave compaction detector 4232, so that the compaction of the road surface below it can be detected by the detection head 2321.

[0040] In the present invention, when the compactor body 1 moves, the motor 421 drives the detection device body 423 to slide in the opposite direction of the compactor body's movement, and the sliding speed of the detection device body is the same as the compactor body's movement speed. The core purpose of this design is to ensure that the detection device body 423 can always remain in the same position to detect the road surface compaction during the compactor's movement, thereby achieving continuous and real-time compaction monitoring. Driven by the motor 421, the detection device body 423 can move in the opposite direction of the compactor body 1 at a speed that matches the compactor's movement speed. This design ensures that the detection device body 423 always remains relatively stationary relative to the road surface during the compactor's movement. In other words, the detection device body 423 can continuously detect the same road surface position at the moment the compactor moves. This relatively stationary detection position ensures that the detection head 2321 can repeatedly and stably obtain compaction data at the same location, thereby improving the accuracy and reliability of the detection results.

[0041] The traditional compaction detection method requires fixed-point detection after the compaction operation is completed, which not only increases the complexity of the construction process, but may also lead to problems of untimely and incomplete detection. The design of the present invention enables the compaction detection to be carried out simultaneously with the compaction operation without the need for additional detection procedures. This synchronous detection method greatly improves construction efficiency and reduces construction time, while also avoiding the problem of rework 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. Construction personnel can adjust the compaction parameters according to the real-time data to ensure that the compaction quality meets the requirements, thereby speeding up the construction progress;

[0042] Furthermore, the present invention utilizes an electromagnetic wave compaction detector 4232 for compaction testing, a non-destructive testing method. This method not only reduces damage to the road surface but also improves testing efficiency and construction quality control. Compared to traditional destructive testing methods, non-destructive testing methods do not require sampling or damaging the road surface, allowing for repeated testing. Furthermore, they are fast and unaffected by weather, making them suitable for real-time monitoring at construction sites. This non-destructive testing method, combined with the synchronous reverse movement of the detection device body 423, further enhances the accuracy and reliability of testing.

[0043] Furthermore, an electric push rod 4233 is mounted at the lower end of the electromagnetic wave compaction detector 4232. Its primary function is to vertically adjust the height of the detector body 423. Through the telescopic movement of the electric push rod 1, the distance between the detector body and the road surface can be adjusted in real time based on road surface unevenness, ensuring that the detection head 2321 maintains stable contact with the road surface. This height adjustment capability enables the detection device to maintain stable detection results even in complex road conditions, preventing poor contact or damage to the detection head due to uneven road surfaces.

[0044] Furthermore, the anti-interference cannula 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. A cavity for accommodating the second electric push rod 4234 is present between the cover plate and the sleeve. The anti-interference cannula 2331 is hollow. The detection head 2321 is disposed in the middle of the anti-interference cannula 2331 and is installed on the output shaft of the second electric push rod 4234 so that the detection head 2321 can be driven to rise and fall by the second electric push rod 4234.

[0045] The distance between the anti-interference cannula 2331 and the ground is fixed. When the detection head 2321 is not testing the compaction of the road surface below it, the detection head 2321 is placed in the anti-interference cannula 2331. When the detection head 2321 is testing the compaction of the road surface below it, the first electric push rod 4233 pushes the anti-interference cannula 2331 downward, inserting the sleeve into the ground. The detection head 2321 is then retracted upward by the second electric push rod 4234. The distance the detection head 2321 is retracted is equal to the distance the first electric push rod 4233 pushes the anti-interference cannula 2331 downward.

[0046] This invention not only optimizes the functionality of the detection device but also significantly improves the accuracy and reliability of compaction testing. The primary function of the anti-interference cannula 2331 is to provide a stable testing environment for the detection head 2321, preventing external interference from affecting the test results. When the detection head is not in use, it is housed within the anti-interference cannula, protecting it from interference from factors such as dust, moisture, chemical corrosion, and mechanical vibration.

[0047] This protection mechanism not only extends the lifespan of the detection head but also reduces detection errors caused by external interference, ensuring the accuracy and reliability of test data. During compaction testing, electric push rod 1 4233 pushes the anti-interference cannula 2331 downward, inserting the sleeve into the ground. Simultaneously, electric push rod 2 4234 retracts the detection head 2321 upward, a distance equal to the distance the anti-interference cannula was inserted into the ground. This design ensures stable contact between the detection head and the road surface, preventing poor contact due to uneven or soft road surfaces. This allows the detection head to perform compaction testing at the optimal position, further improving detection accuracy and reliability. Furthermore, the design of anti-interference cannula 2331 significantly enhances the detection device's adaptability to complex construction environments. Road construction environments are often subject to interference factors such as dust, moisture, chemical corrosion, and mechanical vibration. The anti-interference cannula effectively shields these interferences, ensuring the detection head operates stably in a variety of harsh environments. For example, in humid or chemically corrosive environments, the sleeve and cover prevent moisture and chemicals from entering the detection head, thereby protecting the detection head from damage.

[0048] Furthermore, the buffer device 41 includes a plate body 411, C-shaped connecting ribs 412, and airbags 413. The C-shaped connecting ribs 412 are arrayed on the lower side of the plate body 411. An airbag 413 is installed in each C-shaped connecting rib 412. All airbags 413 adjust their expansion size by creating negative pressure through an air compressor mechanism. One side of the C-shaped connecting rib 412 is an open structure, and one side of the airbag 413 extends to the opening of the C-shaped connecting rib 412. When the air compressor creates positive pressure to inflate the airbag 413, the surface of the airbag 413 near 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 complex construction environments.

[0049] Among them, the surface of the C-shaped connecting rib 412 is provided with outwardly protruding protrusions at the upper and lower ends near its opening. The two protrusions are staggered, and the airbag 413 is recessed inwardly at the corresponding position of the upper protrusion. The motor 421 and the end of the linear track 422 away from the motor 421 are fixed to the plate 411 through each adjacent C-shaped connecting rib 412;

[0050] 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 an air compressor. This adaptive ability enables the buffer device to flexibly adjust the buffering strength according to different road conditions and construction requirements. On uneven 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 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. This design allows the detection device to 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 test data.

[0051] Furthermore, the buffering effect described above can be changed accordingly through manual adjustment, which can effectively improve the adaptability of the equipment.

[0052] Furthermore, a buffer connecting rib 414 is provided on the side of the C-shaped connecting rib 412 away from the airbag 413. The surface of the buffer connecting rib 414 near the C-shaped connecting rib 412 is inclined. The buffer connecting rib 414 and the C-shaped connecting rib 412 are connected by a telescopic rod 415. When the C-shaped connecting rib 412 is tilted by force, the telescopic rod 415 is squeezed and contracted, 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 an impact caused by an 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, playing a preliminary buffering role. Since the surface of the buffer connecting rib is inclined, this design can effectively disperse external forces and avoid concentrated impacts from damaging the device. When the C-shaped connecting rib is tilted under load, the telescopic rod is squeezed and contracted, further absorbing 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 impact force.

[0053] Furthermore, when the C-shaped connecting ribs swing under force, airbag 413 is squeezed. Because the airbag is filled with gas, it elastically expands and contracts when subjected to force. The presence of limiter plate 4121 limits excessive deformation of the airbag, ensuring that the impact force is evenly distributed when the airbag is subjected to force, while also preventing damage to the airbag due to excessive local force.

[0054] In addition, the buffer device 41 also includes a buffer plate 416, which is arranged between the C-shaped connecting rib 412 and the buffer connecting rib 414, and the buffer plate 416 corresponds to the raised portion on the lower side of the surface of the C-shaped connecting rib 412 and abuts against the raised portion on the lower side; the middle part of the buffer plate 416 is curved, and when the C-shaped connecting rib 412 is forced to swing inward, the C-shaped connecting rib 412 squeezes the buffer plate 416. This design gives the buffer plate good elastic properties. When the C-shaped connecting rib 412 is forced to swing inward, the raised portion on its lower side squeezes 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 force on the detection device. This deformation process is similar to the compression and recovery of a spring, which can effectively alleviate the instantaneous impact force and ensure that the detection device remains stable in a dynamic environment.

[0055] Furthermore, the present invention also proposes a road base compacting device with an intelligent compaction system, the road base compacting device comprising a compactor body 1, a material bin 2 mounted on the compactor body 1, a material discharge device 3, and a detection unit 4. The material bin 2 is filled with a filler for laying on the road surface. The material discharge device 3 is connected to a side of the material bin 2 so as to extract the filler in the material bin 2 through the material discharge device 3 and discharge it onto the road surface.

[0056] The detection unit 4 is located between the wheels 11 arranged on the lower side of the compactor body 1. A roller housing 12 is provided at the end of the compactor body 1, and a compacting roller 13 is installed within the roller housing 12. The material discharge 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 at an angle and protrudes from the side of the roller housing 12. The filler is transferred to the discharge pipe 32 through the spiral material lifting pipe 31 and discharged, and the filler is compacted by the compacting roller 13. This inclined design allows the filler to be discharged at a specific angle and speed, ensuring that the filler is evenly laid on the road surface. At the same time, the inclined end helps reduce material accumulation and blockage during the discharge process, thereby improving discharge efficiency.

[0057] The above are merely preferred embodiments of the present invention and therefore cannot be used to limit the scope of the present invention. In other words, equivalent changes and modifications made according to the scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
