Description

Technical Field

[0001] The invention relates to the technical field of road foundation construction, in particular to a road foundation construction compacting device. Background Art

[0002] In existing road paving technology, before paving asphalt or cement, base soil needs to be laid on the road to improve the load-bearing capacity of the road foundation. The existing base soil paving method still uses a transport vehicle to first transport the base soil to the road, then uses a bulldozer to flatten the accumulated base soil, and then uses a roller to compact the base soil. Traditional base soil compaction equipment mainly relies on large rollers or rammers; however, these traditional base soil compaction equipment have some limitations. For example, common straight-cylinder rollers cannot be locally adjusted according to the specific conditions of the road surface, resulting in uneven compaction effect. Although rammers can perform local compaction, their efficiency is low and it is difficult to meet the needs of large-scale construction.

[0003] In addition, in some special scenarios, such as the construction and compaction of ash yard road foundations, traditional base soil compaction equipment also faces challenges. This is because ash yards are mainly used to store fly ash and slag discharged from power plants. The degree of ground compaction is crucial to preventing dust and ensuring the stability of the ash yard. Due to the special environment and material properties of the ash yard, traditional base soil compaction equipment cannot provide sufficient adaptability and efficiency. Summary of the Invention

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0032] Example 1, with reference to Figures 1 to 5 , which is the first embodiment of the present invention, provides a road foundation construction compaction device, which can achieve one-time compaction of a wide foundation by integrating several groups of fixed-amplitude vibration components 14 on a support shaft 13, significantly improving construction efficiency and reducing equipment investment costs. It is particularly suitable for scenes with high foundation flatness and small undulations, including a compaction unit 1, including a mounting frame 11, two groups of shaft sleeves 12 arranged inside the mounting frame 11, a support shaft 13 rotatably arranged inside the two groups of shaft sleeves 12, and a vibration component 14 arranged outside the support shaft 13.

[0033] Furthermore, the mounting frame 11 serves as a supporting base for adjustment of the vibration assembly 14 ; the vibration assembly 14 is used to provide a vibration force for vibrating and compacting the road foundation.

[0034] Furthermore, the vibration assembly 14 includes several groups of fixed sleeves 141 arranged on the outside of the support shaft 13, adjustment parts 142 respectively arranged on the outside of the several groups of fixed sleeves 141, a control part 143 arranged inside the adjustment part 142, a compacting cylinder 144 sleeved on the outside of the adjustment part 142, and a hydraulic vibration part 145 arranged inside the compacting cylinder 144.

[0035] Furthermore, the adjusting member 142 includes three groups of fixing seats 1421 annularly distributed outside the fixing sleeve 141 , and the insides of the three groups of fixing seats 1421 are all embedded with telescopic outer tubes 1422 .

[0036] Furthermore, the control member 143 includes a fixed ring 1431 fixedly arranged on the inner wall of the telescopic outer tube 1422, a control tank 1432 is embedded in the interior of the fixed ring 1431, a first piston 1433 is slidingly arranged in the interior of the control tank 1432, a second piston 1435 is slidingly arranged in the interior of the control tank 1432 and below the first piston 1433, a flow control valve tube 1437 is arranged in the interior of the telescopic outer tube 1422, a fixed jet plate 1438 is fixedly arranged in the interior of the flow control valve tube 1437, a rotating ring 1439 is rotatably arranged in the interior of the flow control valve tube 1437, and an adjustable jet plate 14310 is embedded in the interior of the rotating ring 1439.

[0037] When in use, the mounting frame 11 can be connected to an existing roller vehicle to replace the existing roller drum structure. Driven by the roller vehicle, the support shaft 13 can rotate continuously in the shaft sleeve 12, driving all vibration components 14 to perform circular motion; the hydraulic vibration component 145 in the vibration component 14 is supplied with oil at a constant flow rate to generate a vibration force with a fixed amplitude, and the fixed amplitude vibration force is transmitted to the foundation through the compacting drum 144 to achieve continuous rolling compaction.

[0038] In summary, by integrating several groups of fixed-amplitude vibration components 14 on the same support shaft 13, the support shaft 13 rotates continuously to drive all the compacting cylinders 144 to roll as a whole, and the hydraulic motor 1452 drives the eccentric cam 1453 at a constant flow rate to output a fixed-amplitude vibration force. Each compacting cylinder 144 can complete the compaction of a wide foundation at one time without independent adjustment, replacing traditional step-by-step compaction with mechanical integration. It has a large operating width, a simple structure and low control cost, and is particularly suitable for scenes with high foundation flatness and small undulations. It can significantly improve construction efficiency and reduce equipment cost investment.

[0039] Example 2, reference Figures 1 to 10, which is the second embodiment of the present invention, differs from the first embodiment in that it also includes a feature that enables the compaction device to adaptively adjust the magnitude of the vibration force based on the actual undulations of the road foundation, ensuring good contact between the compaction cylinder 144 and the ground, avoiding insufficient or excessive compaction, and improving the degree of automation and adaptability of the compaction operation. In the previous embodiment, a road foundation construction compaction device included an adjustment member 142.

[0040] Furthermore, the control member 143 also includes a push plate 14311 fixedly arranged on the outside of the rotating ring 1439, a fixing plate 14312 is fixedly arranged inside the telescopic outer tube 1422, and an adjusting tube 14313 is fixedly connected to the inside of the fixing plate 14312.

[0041] Furthermore, the bottom of the second piston 1435 is fixedly connected to the second push rod 1436, and the bottom end of the second push rod 1436 is fixedly provided with the third piston 14314. The third piston 14314 is slidably provided inside the adjusting tube 14313. The bottom end of the adjusting tube 14313 is connected to the arc tube 14315, and the fourth piston 14316 is slidably provided inside the arc tube 14315. The outer side of the fourth piston 14316 is fixedly connected to the arc rod 14317, and the end of the arc rod 14317 away from the fourth piston 14316 is connected to the push plate 14311.

[0042] Furthermore, a first push rod 1434 is provided on the top of the first piston 1433 , and one end of the first push rod 1434 away from the first piston 1433 is connected to the telescopic inner rod 1423 .

[0043] Furthermore, the inner wall of the compacting cylinder 144 is fixedly connected to the side of the connecting block 1424 away from the telescopic inner rod 1423, and the shape of the fitting surface between the connecting block 1424 and the compacting cylinder 144 is set to be arc-shaped.

[0044] Furthermore, the adjustable jet plate 14310 and the fixed jet plate 1438 are fitted together, and both the adjustable jet plate 14310 and the fixed jet plate 1438 are provided with jet holes 14318 that are positioned corresponding to each other.

[0045] Furthermore, the longitudinal cross-section of the control tank 1432 is in the shape of a convex letter "U", and the interior of the control tank 1432 and the area between the first piston 1433 and the second piston 1435 where they are close to each other are filled with hydraulic oil.

[0046] Furthermore, the hydraulic vibrator 145 includes three groups of transmission supports 1451 distributed in a ring shape inside the compacting cylinder 144. The three groups of transmission supports 1451 are fixedly provided with a hydraulic motor 1452 on the side away from the compacting cylinder 144. The output ends of the three groups of hydraulic motors 1452 are all provided with eccentric cams 1453, and the outer sides of the three groups of fixed seats 1421 are all provided with circulating oil pumps 1454.

[0047] Furthermore, the input end of the circulating oil pump 1454 is connected to an oil inlet pipe 1455, and the end of the oil inlet pipe 1455 away from the circulating oil pump 1454 is connected to the flow control valve pipe 1437. The output end of the circulating oil pump 1454 is connected to an oil outlet pipe 1456, and the end of the oil outlet pipe 1456 away from the circulating oil pump 1454 is connected to the oil inlet end of the hydraulic motor 1452. The end of the flow control valve pipe 1437 away from the oil inlet pipe 1455 is connected to an oil delivery pipe 1457, and the end of the oil delivery pipe 1457 away from the flow control valve pipe 1437 is connected to the oil outlet end of the hydraulic motor 1452.

[0048] During use, when the compacting cylinder 144 rolls with the support shaft 13 and encounters undulations in the road surface, the compacting cylinder 144 passively produces a vertical displacement, synchronously driving the connecting block 1424 and the telescopic inner rod 1423 to produce a telescopic movement close to or away from the inside of the telescopic outer tube 1422, and the first push rod 1434 moves synchronously in the same direction as the telescopic inner rod 1423; wherein, when the telescopic inner rod 1423 moves in the direction close to the inside of the telescopic outer tube 1422, the first push rod 1434 moves synchronously in the same direction as the telescopic inner rod 1423 and pushes the first piston 1433, and the first piston 1433 squeezes the hydraulic oil in the convex-shaped control tank 1432, and the oil pressure pushes the second piston 1435, the second push rod 1436 and the third piston 14314 in turn, and the third piston 14314 is pushed in the regulating tube 14313 by the third piston 14314. The thrust is generated, which drives the fourth piston 14316 through the arc tube 14315, driving the arc rod 14317 to slide outward along the inside of the arc tube 14315, and the push plate 14311 moves synchronously with the arc tube 14315 to generate a rotational motion, so that the adjustable jet plate 14310 on the rotating ring 1439 rotates relative to the fixed jet plate 1438, and the overlapping area between the jet holes 14318 at the corresponding positions of the adjustable jet plate 14310 and the fixed jet plate 1438 is changed in real time; the overlapping area directly adjusts the flow capacity of the flow control valve tube 1437, and then steplessly changes the oil supply of the circulating oil pump 1454 to the hydraulic motor 1452, so that the vibration force of the eccentric cam 1453 increases or decreases in real time with the fluctuation of the road surface. The greater the fluctuation, the greater the vibration force generated, thereby realizing adaptive compaction of the road surface.

[0049] In summary, the vertical displacement of the compacting drum 144 caused by the undulation of the road surface is converted into a change in the opening of the jet hole 14318, and then the oil supply of the hydraulic motor 1452 is adjusted to realize automatic adjustment of the vibration force. This adaptive adjustment function enables the compacting device to automatically adjust the vibration force according to the actual undulation of the road surface without manual intervention, thereby improving the degree of automation and adaptability of the compaction operation. In the case of large undulations in the road surface, the device can ensure good contact between the compacting drum 144 and the ground, avoiding insufficient compaction due to insufficient vibration force or road damage due to excessive vibration force. By adjusting the vibration force in real time, the compaction operation is made more uniform and efficient, reducing construction time and labor input, while reducing rework and material waste caused by uneven compaction. It is not only suitable for general road foundation compaction operations, but also can play an important role in special scenarios such as ash yards.

[0050] Example 3, reference Figures 1 to 10 , which is the third embodiment of the present invention, provides a road foundation construction compaction device, which can achieve wide-area compaction operations on complex and uneven roads through the cooperation of multiple independent compaction cylinders 144 with adjustment components 142 and control components 143, so that each group of compaction cylinders 144 can independently sense and adapt to undulations of different heights, automatically adjust the vibration force, thereby improving the uniformity and efficiency of compaction, including a compaction unit 1, including a mounting frame 11, two groups of shaft sleeves 12 arranged inside the mounting frame 11, a support shaft 13 rotatably arranged inside the two groups of shaft sleeves 12, and a vibration component 14 arranged outside the support shaft 13.

[0051] Furthermore, the mounting frame 11 serves as a supporting base for adjustment of the vibration assembly 14 ; the vibration assembly 14 is used to provide a vibration force for vibrating and compacting the road foundation.

[0052] It should be noted that the mounting frame 11 is a connecting frame for the roller drum on a conventional roller. The mounting frame 11 is also provided with a corresponding docking structure that is mechanically connected to the roller, etc., and provides a driving source for the movement of the vibration component 14 through mechanical connection with the roller, etc.

[0053] Furthermore, the vibration assembly 14 includes several groups of fixed sleeves 141 arranged on the outside of the support shaft 13, adjustment parts 142 respectively arranged on the outside of the several groups of fixed sleeves 141, a control part 143 arranged inside the adjustment part 142, a compacting cylinder 144 sleeved on the outside of the adjustment part 142, and a hydraulic vibration part 145 arranged inside the compacting cylinder 144.

[0054] It should be noted that the compacting drum 144 is a hollow cylindrical structure, which is the same as the roller drum on the existing roller, and relies on its own weight to compact the road surface under the action of gravity.

[0055] Furthermore, the adjusting member 142 includes three groups of fixing seats 1421 annularly distributed outside the fixing sleeve 141 , and the insides of the three groups of fixing seats 1421 are all embedded with telescopic outer tubes 1422 .

[0056] Furthermore, the control member 143 includes a fixed ring 1431 fixedly arranged on the inner wall of the telescopic outer tube 1422, a control tank 1432 is embedded in the interior of the fixed ring 1431, a first piston 1433 is slidingly arranged in the interior of the control tank 1432, a second piston 1435 is slidingly arranged in the interior of the control tank 1432 and below the first piston 1433, a flow control valve tube 1437 is arranged in the interior of the telescopic outer tube 1422, a fixed jet plate 1438 is fixedly arranged in the interior of the flow control valve tube 1437, a rotating ring 1439 is rotatably arranged in the interior of the flow control valve tube 1437, and an adjustable jet plate 14310 is embedded in the interior of the rotating ring 1439.

[0057] Furthermore, the adjusting member 142 also includes a telescopic inner rod 1423 slidably arranged inside the telescopic outer tube 1422, and the top of the telescopic inner rod 1423 is fixedly connected to a connecting block 1424, and a spring 1425 is fixedly arranged between the connecting block 1424 and the side close to the fixing seat 1421.

[0058] Furthermore, the control member 143 also includes a push plate 14311 fixedly arranged on the outside of the rotating ring 1439, a fixing plate 14312 is fixedly arranged inside the telescopic outer tube 1422, and an adjusting tube 14313 is fixedly connected to the inside of the fixing plate 14312.

[0059] Furthermore, the bottom of the second piston 1435 is fixedly connected to the second push rod 1436, and the bottom end of the second push rod 1436 is fixedly provided with the third piston 14314. The third piston 14314 is slidably provided inside the adjusting tube 14313. The bottom end of the adjusting tube 14313 is connected to the arc tube 14315, and the fourth piston 14316 is slidably provided inside the arc tube 14315. The outer side of the fourth piston 14316 is fixedly connected to the arc rod 14317, and the end of the arc rod 14317 away from the fourth piston 14316 is connected to the push plate 14311.

[0060] Furthermore, a first push rod 1434 is provided on the top of the first piston 1433 , and one end of the first push rod 1434 away from the first piston 1433 is connected to the telescopic inner rod 1423 .

[0061] Furthermore, the inner wall of the compacting cylinder 144 is fixedly connected to the side of the connecting block 1424 away from the telescopic inner rod 1423, and the shape of the fitting surface between the connecting block 1424 and the compacting cylinder 144 is set to be arc-shaped.

[0062] Furthermore, the adjustable jet plate 14310 and the fixed jet plate 1438 are fitted together, and both the adjustable jet plate 14310 and the fixed jet plate 1438 are provided with jet holes 14318 that are positioned corresponding to each other.

[0063] It should be noted that fixed jet plate 1438 is fixedly mounted within flow control valve tube 1437, while adjustable jet plate 14310 is embedded within rotating ring 1439. The fixed and adjustable jet plates 14310 are in close contact with each other, and each has correspondingly positioned jet holes 14318. In the initial state, the overlap between the jet holes 14318 of fixed and adjustable jet plates 1438 and 14310 is at a basic level. At this point, the oil supply to hydraulic motor 1452 is at a basic level, and the vibration force remains at the initial setting.

[0064] Specifically, when the adjustable jet plate 14310 rotates, the overlapping area of ​​the jet holes 14318 on the adjustable jet plate 14310 and the jet holes 14318 on the fixed jet plate 1438 changes. If the road surface is relatively undulating, the compression stroke of the compacting cylinder 144 increases. After the transmission process described in Example 2, the rotation angle of the adjustable jet plate 14310 increases, and the overlapping area of ​​the jet holes 14318 increases, so that the flow area of ​​the flow control valve pipe 1437 increases, and the circulating oil pump 1454 supplies oil to the hydraulic motor. As the flow of hydraulic oil delivered by 1452 increases, the rotation speed of the hydraulic motor 1452 increases, and the vibration force generated by the eccentric cam 1453 also increases, thereby achieving the effect of automatically increasing the vibration force according to the undulations of the road surface. On the contrary, if the road surface is relatively flat, the compression stroke of the compacting cylinder 144 is smaller, and the overlapping area between the jet hole 14318 on the adjustable jet plate 14310 and the jet hole 14318 on the fixed jet plate 1438 is reduced, the oil supply of the hydraulic motor 1452 is reduced, and the vibration force is reduced, thereby avoiding excessive compaction.

[0065] Furthermore, the longitudinal cross-section of the control tank 1432 is in the shape of a convex letter "U", and the interior of the control tank 1432 and the area between the first piston 1433 and the second piston 1435 where they are close to each other are filled with hydraulic oil.

[0066] Specifically, the control tank 1432 adopts a convex cross-section, and its main function is to disperse the large thrust transmitted by the telescopic inner rod 1423 through a narrow upper and wide lower space design, so that the hydraulic oil forms a more moderate pressure in the control tank 1432, and then allows the second piston 1435 to receive a smaller and more stable thrust, thereby smoothly driving subsequent mechanical actions, preventing system shocks caused by sudden pressure changes, and ensuring the accuracy and stability of vibration force regulation.

[0067] Furthermore, the hydraulic vibrator 145 includes three groups of transmission supports 1451 distributed in a ring shape inside the compacting cylinder 144. The three groups of transmission supports 1451 are fixedly provided with a hydraulic motor 1452 on the side away from the compacting cylinder 144. The output ends of the three groups of hydraulic motors 1452 are all provided with eccentric cams 1453, and the outer sides of the three groups of fixed seats 1421 are all provided with circulating oil pumps 1454.

[0068] Furthermore, the input end of the circulating oil pump 1454 is connected to an oil inlet pipe 1455, and the end of the oil inlet pipe 1455 away from the circulating oil pump 1454 is connected to the flow control valve pipe 1437. The output end of the circulating oil pump 1454 is connected to an oil outlet pipe 1456, and the end of the oil outlet pipe 1456 away from the circulating oil pump 1454 is connected to the oil inlet end of the hydraulic motor 1452. The end of the flow control valve pipe 1437 away from the oil inlet pipe 1455 is connected to an oil delivery pipe 1457, and the end of the oil delivery pipe 1457 away from the flow control valve pipe 1437 is connected to the oil outlet end of the hydraulic motor 1452.

[0069] Specifically, before the equipment is started, sufficient hydraulic oil is pre-stored in the oil inlet pipe 1455, the oil outlet pipe 1456, the oil delivery pipe 1457 and the flow control valve pipe 1437 to prevent the circulating oil pump 1454 from running dry due to lack of oil in the pipeline when the system is started, thereby damaging the equipment. The pre-stored oil ensures that the circulating oil pump 1454 can promptly build up the pressure required by the system, so that the hydraulic motor 1452 can quickly obtain sufficient pressure oil to maintain a stable vibration force output. The pre-stored oil keeps the system in a state of being ready to work at any time. When the road surface fluctuates, the hydraulic system can respond quickly and adjust the vibration force in time to improve the efficiency and quality of the compaction operation, thereby avoiding the circulating oil pump 1454 from inhaling air due to insufficient oil, resulting in cavitation, and further damaging the circulating oil pump 1454 and the hydraulic motor 1452. In addition, sufficient pre-stored oil ensures the continuity and balance of the oil circulation of the entire hydraulic system, which helps to maintain the temperature stability of the oil.

[0070] Furthermore, the transfer support 1451 and the connecting block 1424 are separated and arranged at an angle, and the angle is less than sixty degrees.

[0071] Specifically, the angle setting between the transfer support 1451 and the connecting block 1424 helps to disperse the force transmitted from the compacting cylinder 144 to different directions, making the transfer support 1451 more stable in the process of transmitting force to the hydraulic motor 1452, and preventing structural damage caused by excessive concentration of force. The existence of the angle can change the relative movement direction between the transfer support 1451 and the connecting block 1424, making the movement of the hydraulic motor 1452 more stable, and helping to improve the adjustment accuracy of the vibration force. At the same time, the angle setting can reasonably arrange various components in a limited space, avoid mutual interference between components, and make the structure of the entire vibration assembly 14 more compact and reasonable.

[0072] Furthermore, the interiors of the oil outlet pipe 1456 , the oil inlet pipe 1455 and the flow control valve pipe 1437 are all filled with hydraulic oil.

[0073] When in use, the vibratory compacting device is installed on a suitable construction machine and connected to the hydraulic system. The hydraulic pump is started to ensure that the circulating oil pump 1454 starts working, the hydraulic oil circulates in the system, and the hydraulic motor 1452 enters the standby state. The operator controls the construction machinery and equipment to move the compacting unit 1 to the position of the foundation to be compacted. The support shaft 13 starts to rotate in the shaft sleeve 12, driving all the compacting cylinders 144 to contact the foundation surface and prepare for compaction operations. The compacting cylinders 144 roll on the foundation surface and start compaction operations. The circulating oil pump 1454 starts working, pumping the hydraulic oil to circulate in the pipeline and supplying oil to the hydraulic motor 1452 at a constant flow rate, thereby generating a fixed amplitude vibration force, which is suitable for efficient and continuous compaction of flat foundations. When the compacting cylinder 144 encounters undulations in the road surface, the vertical displacement generated generates a telescopic movement relative to the telescopic outer tube 1422 through the connecting block 1424 and the telescopic inner rod 1423. The telescopic inner rod 1423 can drive the first push rod 1434 to transmit the thrust to the first piston 1433. The first piston 1433 squeezes the hydraulic oil in the convex control tank 1432. The oil pressure pushes the second piston 1435 and the second push rod 1436, thereby driving the third piston 14314 to move. The third piston 14314 generates a thrust in the regulating tube 14313, drives the fourth piston 14316 through the arc tube 14315, drives the arc rod 14317 to rotate and extend and push the push plate 14311. Conversely, the telescopic inner rod 1423 can also be used to reverse these movements in sequence. The process is carried out in sequence, so that the adjustable jet plate 14310 rotates forward and backward relative to the fixed jet plate 1438, and the overlapping area between the jet holes 14318 of the fixed jet plate 1438 and the adjustable jet plate 14310 is changed, so as to adjust the oil supply of the hydraulic motor 1452, so that the vibration force increases or decreases in real time with the undulation of the road surface. Multiple groups of compacting cylinders 144 are arranged axially along the support shaft 13, and each group of compacting cylinders 144 can independently sense and adapt to the undulations of the ground at different heights. Multiple groups of compacting cylinders 144 each adjust the vibration force to achieve wide-range compaction with segmented force adjustment. The compaction operation continues, and the compacting cylinders 144 keep rolling and adjust the vibration force in real time to ensure that the compaction effect is uniform and consistent. The operator can appropriately adjust the moving speed of the construction machinery and equipment according to the construction progress and foundation conditions.

[0074] In summary, multiple sections of compacting drums 144 are arranged axially along the support shaft 13, and each group of compacting drums 144 independently senses and adapts to undulations of different heights. Multiple groups of compacting drums 144 adjust their own vibration force. Through multiple sections of independent compacting drums 144 and their respective closed-loop adjustment systems, wide-width compaction of the road surface with complex undulations can be completed in one roll. Each group of compacting drums 144 can independently adjust the vibration force to adapt to undulations of different heights, improve the compaction uniformity and efficiency, and automatically match the vibration force without human intervention, reduce overpressure or underpressure, reduce rework rate and material waste, shorten the construction period, and improve construction quality and efficiency. At the same time, the use of mechanical hydraulic adjustment drive can adapt to special scenarios such as ash field road foundation construction, with high local reliability, reduced failures, reduced maintenance costs, and ensure long-term stable operation.
