Description

Technical Field

[0001] This utility model belongs to the field of compaction machine technology, specifically relating to an adjustable pressure compaction machine for miscellaneous fill and silty soil pipeline networks. Background Technology

[0002] A compactor for miscellaneous fill and silty soil is an engineering device specifically designed for the safe and efficient backfilling and compaction of pipelines and trenches (pipelines) in foundations with complex composition, loose soil (miscellaneous fill), or high water content and low strength.

[0003] In existing technologies, compactors for fill and silty soil primarily utilize an engine-driven hydraulic pump to store energy in an accumulator, simultaneously raising the hammer to a set height before compaction. However, because the compactor plate exerts a downward pressure on the ground upon contact, excessive compaction force can diffuse across the ground and directly transfer to the pipeline network, potentially exceeding its capacity and causing cracks, loose joints, and compromised sealing and lifespan. Furthermore, compaction of fill and silty soil often involves trenches, where the compactor plate dimensions may mismatch with the trench width. Utility Model Content

[0004] This utility model provides an adjustable pressure compactor for pipelines using miscellaneous fill and silty soil, which aims to solve the problem of poor practicality of existing compactors for miscellaneous fill and silty soil due to their inability to achieve buffering and adapt to trench compaction operations.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a pressure-adjustable compactor for miscellaneous fill and silty soil pipeline networks, comprising: A drive unit has an energy storage device; the power unit of the energy storage device is connected to a mounting cover. The base has its top end slidably connected to the mounting cover; the bottom of the base has an open cavity. The system includes multiple buffer structures, each of which is housed within the mounting cover and connected to both the mounting cover and the base. A connecting component, disposed in the open cavity, has two sets of spaced-apart plugs, the connecting component being used to drive the two sets of plugs to move relative to each other or in opposite directions; The ramming plate has receiving parts for the two sets of insertion parts to be inserted into respectively; the ramming plate is used to limit and lock the two sets of insertion parts that move in opposite directions after contacting the base.

[0006] In one possible implementation, the mounting cover has a sliding cavity with an open bottom, and limiting plates are provided at intervals around the open portion of the sliding cavity; the top end of the base is slidably connected to the sliding cavity, and an auxiliary plate corresponding to the limiting plate is provided around the top end of the base; Multiple elastic elements are evenly distributed between the limiting plate and the auxiliary plate.

[0007] In one possible implementation, each of the buffer structures includes: The telescopic rod is fixedly connected at one end to the bottom surface of the sliding cavity and at the other end to the base; A spring, fitted onto the telescopic rod, is used to continuously bounce the base, giving the base a tendency to continuously move outward from the sliding cavity.

[0008] In one possible implementation, the connection component includes: Two guide rods are provided, which are spaced apart in the horizontal direction. The two ends of each guide rod are fixedly connected to the inner wall of the opening. The length direction of the guide rod is defined as the first direction, and the horizontal direction perpendicular to the first direction is defined as the second direction. A fixed box is disposed between the two guide rods and is fixedly connected to the bottom surface of the open cavity; Two slides are provided, and the two slides are respectively arranged on both sides of the fixed box along the first direction, and each slide is slidably connected to the two guide rods; each slide has a plurality of plug-in pins on the side facing away from the other slide, each plug-in pin is arranged along the first direction, and each plug-in pin is spaced apart along the second direction, and each plug-in pin forms the plug-in part; An adjustment structure is installed in the fixed box and connected to the two slides, used to drive the slides to move relative to each other or in opposite directions.

[0009] In one possible implementation, the ramming plate is provided with two spaced vertical plates; each vertical plate is provided with a plurality of insertion holes corresponding to each of the insertion posts, and the insertion holes are combined to form the receiving part.

[0010] In one possible implementation, the adjustment structure includes: The sliding plate is slidably disposed in the fixed box along the second direction; the top of the sliding plate is provided with two adjusting columns; An adjusting screw is provided along the second direction and is rotatably connected to the fixed box. The adjusting screw is screw-connected to a nut sleeve provided at the bottom of the slide plate. One end of the adjusting screw extends out of the fixed box and is connected to a handwheel. Two connecting plates are provided, which are spaced apart along the first direction and are slidably connected to the fixed box. The two connecting plates are respectively fixedly connected to the two slide blocks. Each connecting plate is provided with an oblique elongated opening. The two connecting plates are slidably connected to the two adjusting columns through the oblique elongated openings. As the sliding plate moves, the two adjusting columns drive the two connecting plates to move relative to each other or in opposite directions in the first direction.

[0011] In one possible implementation, a window is provided on the side wall of the base, the opening is positioned corresponding to the handwheel, and a sealing door is provided at the window.

[0012] In one possible implementation, the bottom end of the base is provided with an elastic sealing strip that surrounds the opening.

[0013] The adjustable pressure compactor for miscellaneous fill and silty soil pipelines provided in this implementation, compared with existing technologies, generates a reaction force when the compactor plate contacts the ground. At this time, the base, due to its sliding connection with the mounting cover, will displace along the inner wall of the mounting cover. Multiple buffer structures between the mounting cover and the base will be stressed simultaneously. These multiple buffer structures can absorb some energy through deformation when the compaction reaction force is generated, reducing the force and stroke of the base pressing the ground downwards, thereby reducing the intensity of the compaction force diffused on the ground, preventing the pipeline network from being subjected to excessive force, reducing the risk of pipeline cracks and loosening of joints, and ensuring the sealing performance and service life of the pipeline network. When it is necessary to adapt to trenches of different widths, the connecting component drives the two sets of plug-in parts to move relative to each other, which can loosen the clamping with the receiving part of the compactor plate, remove the old compactor plate, and replace it with a new size compactor plate. After that, the connecting component drives the two sets of plug-in parts to move back and forth, so that the plug-in parts insert into the receiving part of the new compactor plate, forming a stable limiting clamping, and completing the compactor plate replacement. This process allows for the replacement of tamping plates of different sizes without the need for complex tools, adapting to the compaction needs of trenches of different widths in miscellaneous fill and silty soil, effectively solving the problem of poor tamping plate adaptability in existing technologies.

[0016] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] Please refer to the following: Figure 1 and Figure 2 This invention provides a description of an adjustable pressure compactor for miscellaneous fill and silty soil pipeline networks. The adjustable pressure compactor includes a drive base 10, a base 20, a buffer structure 30, a connecting assembly 40, and a compaction plate 50. The drive base 10 can be connected to a walking device. The drive base 10 has an accumulator. The power unit of the accumulator is connected to a mounting cover 11. The top of the base 20 is slidably connected to the mounting cover 11. The bottom of the base 20 has an open cavity 22. Multiple buffer structures 30 are provided, each housed within the mounting cover 11, and each buffer structure 30 is connected to both the mounting cover 11 and the base 20. The connecting assembly 40 is located within the open cavity 22 and has two sets of spaced-apart insertion parts. The connecting assembly 40 can drive the two sets of insertion parts to move relative to each other or in opposite directions. The compaction plate 50 has a receiving part for the two sets of insertion parts to be inserted into. After the ramming plate 50 comes into contact with the base 20, it is locked in place by two sets of receiving parts and two sets of oppositely moving insertion parts.

[0018] When the equipment is running, the accumulator of the drive seat 10 first transmits energy to the mounting cover 11 through the power unit, and at the same time stores power for the hammer lifting (subsequent tamping action).

[0019] Compared with the prior art, the adjustable pressure compactor for miscellaneous fill and silty soil pipelines provided in this embodiment generates a reaction force when the compaction plate 50 contacts the ground. At this time, the base 20 will be displaced along the inner wall of the mounting cover 11 due to its sliding connection with the mounting cover 11. The multiple buffer structures 30 between the mounting cover 11 and the base 20 will be subjected to force simultaneously. When the impact reaction force is generated, the multiple buffer structures 30 can absorb part of the energy through deformation, reduce the force and stroke of the base 20 pressing the ground downward, thereby reducing the impact force intensity diffused on the ground, preventing the pipeline from bearing excessive force, reducing the risk of pipeline cracks and loose joints, and ensuring the sealing performance and service life of the pipeline. When it is necessary to adapt to trenches of different widths, the connecting component 40 moves the two sets of plug-in parts relative to each other, loosening the clamping of the receiving part of the tamping plate 50. After removing the old tamping plate 50 and replacing it with a new sized tamping plate 50, the connecting component 40 moves the two sets of plug-in parts back to back, allowing the plug-in parts to insert into the receiving part of the new tamping plate 50, forming a stable limiting clamping, thus completing the replacement of the tamping plate 50. This process can replace tamping plates 50 of different sizes without complicated tools, adapting to the compaction needs of trenches of different widths in miscellaneous fill and silty soil, effectively solving the problem of poor adaptability of tamping plates 50 in existing technologies.

[0020] In some embodiments, the mounting cover 11 may be adopted as follows: Figure 2 The structure shown. See also Figure 2 The mounting cover 11 has a sliding cavity 12 with an open bottom, and a limiting plate 13 is provided at intervals around the open part of the sliding cavity 12. The top of the base 20 is slidably connected to the sliding cavity 12, and an auxiliary plate 21 corresponding to the limiting plate 13 is provided around the top of the base 20.

[0021] Among them, multiple elastic elements 14 are evenly distributed between the limiting plate 13 and the auxiliary plate 21.

[0022] The limiting plate 13 corresponds to the auxiliary plate 21, which can ensure that the base 20 is limited and prevent the base 20 from disengaging from the sliding cavity 12. At the same time, multiple elastic elements 14 are provided on the limiting plate 13, which can buffer the auxiliary plate 21 when it contacts the limiting plate 13 after the force is released by each buffer structure 30, so as to avoid rigid contact between the auxiliary plate 21 and the limiting plate 13, and thus effectively prevent the limiting plate 13 from deforming after long-term use.

[0023] Specifically, the elastic element 14 can be a shock-absorbing rubber block.

[0024] In some embodiments, the buffer structure 30 described above may employ, for example... Figure 2 The structure shown. See also Figure 2Each buffer structure 30 includes a telescopic rod 31 and a spring 32. One end of the telescopic rod 31 is fixedly connected to the bottom surface of the sliding cavity 12, and the other end is fixedly connected to the base 20. The spring 32 is sleeved on the telescopic rod 31 and can continuously bounce the base 20, so that the base 20 has a tendency to continuously move outward from the sliding cavity 12.

[0025] Spring 32, due to its own elastic force, pushes base 20 outward from sliding cavity 12. When tamping plate 50 contacts the ground and generates a counter-impact force, this force is transmitted through tamping plate 50 to base 20, pushing base 20 inward from sliding cavity 12. At this time, spring 32, sleeved on telescopic rod 31, is compressed by the base 20 and the bottom surface of sliding cavity 12, gradually accumulating its elastic potential energy. Simultaneously, it converts the kinetic energy of the counter-impact force into elastic potential energy, achieving a force-dissipating effect. Telescopic rod 31 restricts the deformation direction of spring 32 during compression, preventing spring 32 from failing due to lateral displacement and ensuring that spring 32 always extends and retracts axially. When the counter-impact force weakens, the elastic potential energy stored in spring 32 is released, pushing base 20 back to its axial position along telescopic rod 31, causing tamping plate 50 to return to its initial position, completing one buffer cycle.

[0026] The compression action of spring 32 reduces the stroke of the ground. When base 20 moves into sliding cavity 12, spring 32 compresses and absorbs part of the displacement, reducing the downward pressure of base 20 on the ground and weakening the direct pressure on the ground. This reduces the diffusion and transmission of the impact force to the underground pipeline network, preventing the pipeline network from being subjected to excessive force. Furthermore, it reduces the duration of the impact force. The absorption of the counter-impact force by spring 32 shortens the duration of the impact force acting on the ground. According to mechanical principles, shortening the duration of force action reduces the cumulative impact damage to the pipeline network, further protecting the integrity of the pipeline and the sealing of the joints.

[0027] In some embodiments, the connection component 40 described above may employ, for example... Figure 3 and Figure 4 The structure shown. See also Figure 3 and Figure 4 The connecting assembly 40 includes a guide rod 41, a fixed box 42, a slide 43, and an adjustment structure 45.

[0028] Two guide rods 41 are provided, spaced apart horizontally, with each guide rod 41 having its two ends fixedly connected to the inner wall of the opening 22. The length direction of the guide rod 41 is defined as the first direction, and the horizontal direction perpendicular to the first direction is defined as the second direction. A fixed box 42 is positioned between the two guide rods 41 and fixedly connected to the bottom surface of the opening 22. Two slides 43 are provided, positioned along the first direction on both sides of the fixed box 42, and each slide 43 is slidably connected to both guide rods 41. Each slide 43 has multiple insertion posts 44 on its side facing away from the other slide 43. Each insertion post 44 is positioned along the first direction and spaced apart along the second direction, forming an insertion part. An adjustment structure 45 is located in the fixed box 42 and connected to the two slides 43, enabling the slides 43 to move relative to each other or in opposite directions.

[0029] When the tamping plate 50 needs to be replaced to fit trenches of different widths, the operator controls the adjusting structure 45 to output power and move the two slides 43 along the guide rod 41. When the old tamping plate 50 needs to be removed, the adjusting structure 45 moves the two slides 43 relative to each other (towards the fixed box 42), and the insertion pins 44 on the slides 43 move closer and away from the receiving part of the old tamping plate 50, at which point the old tamping plate 50 can be removed. When a new tamping plate 50 needs to be installed, the receiving part of the new tamping plate 50 is aligned with the two sets of insertion pins 44, and the adjusting structure 45 then moves the two slides 43 away from each other (away from the fixed box 42), and the insertion pins 44 are inserted into the receiving part of the new tamping plate 50 until a stable limit is formed, completing the replacement of the tamping plate 50.

[0030] The adjusting structure 45 moves the slide 43 along the guide rod 41, enabling rapid connection and separation of the insertion part and the receiving part. Different sizes of tamping plates 50 can be replaced without disassembling the base 20 or other large components, adapting to the compaction needs of trenches of various widths in miscellaneous fill and silty soil, thus improving the equipment's applicability. The guiding effect of the guide rod 41 ensures the precise movement trajectory of the slide 43, guaranteeing its stability, preventing misalignment between the insertion post 44 and the receiving part, reducing disassembly and assembly difficulty, and improving replacement efficiency.

[0031] In some embodiments, the aforementioned ramming plate 50 may be adopted as follows: Figure 3 and Figure 4 The structure shown. See also Figure 3 and Figure 4 The ramming plate 50 has two spaced vertical plates 51. Each vertical plate 51 has multiple insertion holes 52 that correspond one-to-one with each insertion post 44, and the insertion holes 52 are combined to form a receiving part.

[0032] The upright plate 51 enhances the structural strength of the receiving part, prevents deformation of the insertion hole 52 due to repeated insertion and removal, and extends the service life of the tamping plate 50. At the same time, the one-to-one correspondence design between the insertion hole 52 and the insertion post 44 allows the tamping plate 50 to be quickly aligned without repeated adjustments during installation, greatly improving the efficiency of disassembly and assembly. It is especially suitable for scenarios where the tamping plate 50 needs to be frequently replaced on construction sites with miscellaneous fill and silty soil, effectively solving the problems of difficult alignment and easy damage of the tamping plate 50 in the existing technology.

[0033] In some embodiments, the adjustment structure 45 described above can be as follows: Figure 3 The structure shown. See also Figure 3 The adjustment structure 45 includes a sliding plate 451, an adjusting screw 452, and a connecting plate 453.

[0034] The slide plate 451 is slidably mounted in the fixed box 42 along the second direction. Two adjusting posts 454 are provided on the top of the slide plate 451. An adjusting screw 452 is positioned along the second direction and rotatably connected to the fixed box 42. The adjusting screw 452 is screw-fitted with a nut sleeve located at the bottom of the slide plate 451. One end of the adjusting screw 452 extends out of the fixed box 42 and is connected to a handwheel 456. Two connecting plates 453 are provided, spaced apart along the first direction and slidably connected to the fixed box 42. Each connecting plate 453 is fixedly connected to two sliding blocks 43. Each connecting plate 453 has an oblique elongated opening 455. The two connecting plates 453 are slidably connected to the two adjusting posts 454 through the oblique elongated openings 455.

[0035] As the slide plate 451 moves, the two adjusting columns 454 drive the two connecting plates 453 to move relative to each other or in opposite directions in the first direction.

[0036] When the operator turns the handwheel 456, the handwheel 456 drives the adjusting screw 452 to rotate around its own axis. Since the adjusting screw 452 is screwed into the nut sleeve of the slide plate 451, and the slide plate 451 is restricted by the fixed box 42 to slide only in the second direction, the rotational motion of the screw is converted into the linear motion of the slide plate 451 (moving back and forth in the second direction). When the slide plate 451 moves, the two adjusting columns 454 at the top move synchronously in the second direction. The adjusting columns 454 are inserted into the oblique elongated opening 455 of the connecting plate 453. The guiding effect of the oblique elongated opening 455 converts the second direction movement of the adjusting columns 454 into the first direction movement of the connecting plate 453. When the slide plate 451 moves in the second direction inside the fixed box 42, the adjusting column 454 will push the connecting plate 453 to move in opposite directions in the first direction, thereby causing the two slides 43 to move in opposite directions (the plug-in column 44 is inserted into the socket 52), or the adjusting column 454 will pull the connecting plate 453 to move relative to each other in the first direction, thereby causing the two slides 43 to move relative to each other (the plug-in column 44 is pulled out of the socket 52).

[0037] Specifically, the fixed box 42 is provided with a guide sliding space for the sliding plate 451 to slide, and a limiting sliding space for the two connecting plates 453 to slide and connect. The limiting sliding space is connected to the guide sliding space and the limiting sliding space passes through the fixed box 42.

[0038] Manual adjustment is achieved via handwheel 456, which is simple to operate and requires no external power. The screw drive of adjusting screw 452 has a self-locking function, preventing the slide plate 451 from moving due to vibration after it has been moved to the target position, ensuring a stable connection between the slide block 43 and the tamping plate 50, and preventing the insertion post 44 from loosening during tamping. The motion conversion design of the slanted elongated opening 455 can convert the small stroke of the slide plate 451 into the large stroke of the connecting plate 453. Only a few turns of handwheel 456 are needed to achieve a large movement of the slide block 43, improving the efficiency of tamping plate 50 replacement.

[0039] In some embodiments, the base 20 may be as follows: Figure 3 The structure shown. See also Figure 3 The base 20 has a window on its side wall, the opening of which corresponds to the position of the handwheel 456, and a sealing door 24 is provided at the window.

[0040] The corresponding arrangement of the window and handwheel 456 allows operators to directly access the handwheel 456 without disassembling the base 20 or other components. This is especially beneficial in construction sites with limited surrounding space, avoiding the cumbersome operation caused by disassembling components and improving the efficiency of replacing the tamping plate 50. Furthermore, when the sealing door 24 is closed, it prevents impurities such as gravel, mud, and water from the fill soil and silty soil from entering the open cavity 22.

[0041] The 24-opening sealed door features a hinged structure and is equipped with a door lock.

[0042] In some embodiments, the base 20 may be as follows: Figure 1 The structure shown. See also Figure 1 The bottom end of the base 20 is provided with an elastic sealing strip 23, which surrounds the open mouth 22.

[0043] The sealing effect of the elastic sealing strip 23 can effectively prevent fine particles, mud, water and other impurities in the fill and silty soil from entering the open cavity 22 of the base 20, ensuring the cleanliness of the inside of the open cavity 22. Moreover, the elastic deformation of the elastic sealing strip 23 can help the buffer structure 30 absorb part of the impact reaction force, avoid rigid contact between the base 20 and the tamping plate 50, and reduce damage at the connection between the tamping plate 50 and the base 20.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
