Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a compaction device for earthwork backfilling. Background Technology

[0002] The use of plate compactors as compaction equipment in earthwork backfilling projects is mainly due to their structural characteristics, working principle and high adaptability to earthwork backfilling scenarios, especially when dealing with narrow spaces, special soil types or delicate operations.

[0003] A mechanical plate compactor for construction engineering, disclosed in Chinese Patent Publication No. CN219157626U, includes a housing and polarizing blocks. The polarizing blocks are installed in a polarizer housing, which is mounted on the bottom plate of the plate compactor. The polarizing blocks generate high-frequency vibrations, causing resonance between the compactor plate and soil particles, disrupting the internal friction between the soil particles and promoting particle rearrangement and compaction. However, based on existing compaction equipment and technologies, conventional plate compactors typically advance at a constant speed during compaction. While this may be effective for uniform soil, it can lead to insufficient compaction cycles on soft surfaces due to the high speed, failing to adequately remove air and moisture from the soil and affecting compaction efficiency. Conversely, on harder surfaces, it can cause over-compaction, increasing energy consumption and potentially damaging the road structure. Furthermore, the inability to automatically adjust the speed requires manual adjustment based on experience, increasing operational complexity and reducing efficiency. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.

[0026] like Figures 1 to 7 As shown, a compaction device for earthwork backfilling includes a mounting box 1, a compaction plate 2 installed at the bottom of the mounting box 1, a polarization component 3 rotatably installed inside the mounting box 1, a drive component 4 for controlling the rotation of the polarization component 3 on the top of the mounting box 1, an adjustment component 5 for adjusting its centrifugal force on the polarization component 3, and a handle 6 fixedly installed on the rear side of the mounting box 1.

[0027] like Figures 2 to 7 As shown, the polarization component 3 includes a rotating shaft 301. A fixing seat 302 is fixedly provided on the outer surface of the rotating shaft 301. Multiple first pistons 303 are inserted into the fixing seat 302. An eccentric part 304 is fixedly installed at the end of the multiple first pistons 303 away from the rotating shaft 301. A second bushing 9 is fixedly installed on both ends of the mounting box 1 corresponding to the two ends of the rotating shaft 301. Both ends of the rotating shaft 301 are connected to the second bushing 9 through bearings. By using the second bushing 9 and bearings, the friction force when the rotating shaft 301 rotates can be reduced, and the stability of the rotating shaft 301 when rotating can be improved. A main oil chamber 3011 is opened inside the rotating shaft 301. A secondary oil chamber 3021 connected to the main oil chamber 3011 is opened on the fixing seat 302 at the position of the multiple first pistons 303. Hydraulic oil is provided inside both the main oil chamber 3011 and the secondary oil chamber 3021.

[0028] like Figures 2 to 7As shown, the adjusting assembly 5 includes a second piston 501 slidably disposed at one end of the main oil chamber 3011. A lead screw 502 is rotatably mounted on the end of the second piston 501 facing the outside of the rotating shaft 301. A handle 503 is fixedly mounted on the end of the lead screw 502 away from the second piston 501. A threaded hole adapted to the lead screw 502 is opened on the end of the rotating shaft 301 near the lead screw 502. Elastic elements 3031 are fixedly mounted between the ends of multiple first pistons 303 away from the eccentric member 304 and the inner wall of the main oil chamber 3011. By rotating the lead screw 502 with the handle 503, the second piston 501 slides into the main oil chamber 3011, allowing the oil inside the main oil chamber 3011 to enter the auxiliary oil chamber 3021. Then, the auxiliary oil chamber... The oil pressure inside 3021 gradually increases. When the oil pressure is greater than the elastic force of the elastic element 3031, the first piston 303 will cause the eccentric element 304 to move away from the rotating shaft 301. At this time, the centrifugal force of the eccentric element 304 will also increase. By rotating the screw 502 in the opposite direction through the throttle 503, the second piston 501 will slide outward from the main oil chamber 3011, and the space inside the main oil chamber 3011 will increase. Then the oil pressure inside the auxiliary oil chamber 3021 gradually decreases. When the oil pressure is less than the elastic force of the elastic element 3031, the elastic element 3031 will cause the first piston 303 and the eccentric element 304 to move towards the rotating shaft 301. At this time, the centrifugal force of the eccentric element 304 will also decrease.

[0029] like Figures 1 to 3 As shown, the drive assembly 4 includes a drive component 401 fixedly mounted on the top of the mounting box 1 (the drive component 401 in this application can be a motor; this is only an example and does not impose any limitations on it). A connecting shaft 402 is fixedly mounted on the output end of the drive component 401. A first pulley 403 is fixedly mounted on the outer surface of the connecting shaft 402. A second pulley 404 is fixedly mounted on the outer surface of the rotating shaft 301 at a position corresponding to the first pulley 403. The first pulley 403 and the second pulley 404 are connected by a transmission belt 405. An isolation cover 7 is fixedly mounted on the top of the mounting box 1 at a position corresponding to the connecting shaft 402. The isolation cover 7 is located on the connecting shaft 402. Both ends are fixedly installed with first bushings 8. Both ends of the connecting shaft 402 are connected to the first bushings 8 through bearings. The mounting box 1 has a movable groove at the position corresponding to the transmission belt 405. By using the first bushings 8 and bearings, the friction force when the connecting shaft 402 rotates can be reduced, and the stability of the connecting shaft 402 when rotating can be improved. The connecting shaft 402 is controlled to rotate by the driving component 401. Then the connecting shaft 402 drives the first pulley 403 to rotate. After that, the first pulley 403 controls the second pulley 404 to rotate through the transmission belt 405. At this time, the second pulley 404 can drive the polarization component 3 to work, so that the tamping plate 2 can perform tamping work.

[0030] The work process is as follows:

[0031] S1: As Figures 2 to 7As shown, during adjustment, the screw 502 is rotated by the throttle 503, causing the second piston 501 to slide into the main oil chamber 3011, allowing the oil inside the main oil chamber 3011 to enter the auxiliary oil chamber 3021. Then, the oil pressure inside the auxiliary oil chamber 3021 gradually increases. When the oil pressure is greater than the elastic force of the elastic element 3031, the first piston 303 will cause the eccentric element 304 to move away from the rotating shaft 301. At this time, the centrifugal force of the eccentric element 304 will also increase.

[0032] S2: As Figures 2 to 7 As shown, by rotating the screw 502 in the opposite direction by the throttle 503, the second piston 501 slides outward from the main oil chamber 3011, the space inside the main oil chamber 3011 increases, and then the oil pressure inside the auxiliary oil chamber 3021 gradually decreases. When the oil pressure is less than the elastic force of the elastic element 3031, the elastic element 3031 will cause the first piston 303 and the eccentric element 304 to move towards the direction of the rotating shaft 301. At this time, the centrifugal force of the eccentric element 304 will also decrease.

[0033] S3: As Figures 2 to 5 As shown, after adjustment, the connecting shaft 402 is rotated by the drive component 401, and then the connecting shaft 402 drives the first pulley 403 to rotate. After that, the first pulley 403 controls the second pulley 404 to rotate through the transmission belt 405. At this time, the second pulley 404 can drive the polarization component 3 to work, so that the compaction plate 2 can perform compaction work.

[0034] S4: When the equipment encounters a soft road surface, the centrifugal force of the eccentric part 304 is increased by adjusting the component 5, and the compaction force of the compaction plate 2 will also increase accordingly. The rotation speed of the drive component 401 will decrease accordingly, and the travel speed of the equipment will also slow down. This allows for more thorough compression of soil particles, breaking the soil pore structure, accelerating the discharge of air and moisture, significantly improving soil density, and avoiding roadbed settlement or road surface cracking caused by insufficient compaction.

[0035] S5: When the equipment is operating on a harder road surface, the centrifugal force of the eccentric part 304 is reduced by adjusting component 5, and the compaction force of the compaction plate 2 is also reduced. The rotation speed of the drive component 401 is increased accordingly, and the travel speed of the equipment is also increased. This reduces the number of compaction times per unit area, prevents the road structure layer from being "crushed" or fatigue cracks from being generated due to excessive vibration energy, and protects the original road strength.

[0036] S6: In summary, when working on uneven foundations (such as uneven backfill soil), parameters can be adjusted in real time to strengthen compaction of soft areas and lightly compact hard areas, avoiding the problem of "insufficient compaction in soft areas and excessive compaction in hard areas" that occurs with traditional fixed parameter settings. It is especially suitable for projects with high requirements for the protection of the original road surface, such as urban road reconstruction.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
