Description

Technical Field

[0001] This invention relates to the field of roadbed construction technology, specifically to a pile-filling crushed stone slab compaction device. Background Technology

[0002] In the foundation treatment of highways, railways, and buildings, especially after the use of pile foundations (such as CFG piles, pipe piles, bored piles, etc.) in soft soil treatment, the backfilling and compaction of crushed stone between the piles is a crucial process. Its core purpose is to fill and compact crushed stone in the gaps between the piles, forming a stable "pile-cushion layer" composite stress system together with the piles. This system evenly transfers the upper load to the piles and the soil between them, preventing stress concentration and also serving to drain water and adjust the pile-soil stress ratio.

[0003] When the pile spacing is small, large ramming equipment cannot travel between the pile heads. In this case, using a small excavator in conjunction with a plate vibratory compactor and a small double-drum roller for compaction effectively overcomes the problem of ensuring compaction quality due to the narrow gap between the pile caps. However, in actual compaction operations, to avoid the plate compactor hitting and damaging the pile heads, and because the excavator operator controls the excavator to adjust the position of the plate compactor, the operator is at a certain distance from the plate compactor, making it difficult to directly observe the position of the plate compactor relative to the pile heads. Especially in some special areas, the excavator arm can obstruct the view. All of these factors can adversely affect the compaction of the crushed stone layer between the piles. Summary of the Invention

The connecting plates at the ends of one of the longitudinal sliding arms are staggeredly distributed in the height direction with respect to the other longitudinal sliding arm.

[0009] Optionally, the bottom height of the longitudinal limiting plate is greater than the top height of the bottom plate of the plate compactor, and when the longitudinal limiting plates are received in the upper area above the bottom plate of the plate compactor, the two longitudinal limiting plates can be respectively clamped on the front and rear sides of the housing of the plate compactor.

[0010] Optionally, the lateral limiting plate includes: A rigid plate body fixedly installed on the outer side surface of the longitudinal sliding seat; Buffer plate bodies fixedly arranged on the front and rear sides of the outer side surface of the rigid plate body; A plurality of rotating rods rotatably arranged in the middle of the rigid plate body; The outer ends of the rotating rods extend out from the middle of the outer side surface of the rigid plate body, and the outer side surface of the buffer plate body is located outside the outer surface of the rotating rods.

[0011] Optionally, the outer side surface of the rigid plate body is flush with the outer side surface of the bottom plate of the plate compactor, and there is a gap between the bottom of the rigid plate body and the bottom plate of the plate compactor.

It should be noted that in this specification, relational terms such as "first" and "second" are only used to distinguish one entity from several other entities, and do not necessarily require or imply any actual relationship or order between these entities.

[0023] like Figure 1 As shown, the pile-filling crushed stone slab compaction equipment of this application includes a plate compactor 1 and a guiding mechanism disposed on the side of the plate compactor 1. The guiding mechanism includes: The longitudinal slide block 2 is slidably disposed on the side of the plate compactor 1 in the front-back direction; Two longitudinal sliding arms 3 are slidably disposed on the top of the longitudinal slide block 2 in the front-back direction. The two longitudinal sliding arms 3 are distributed vertically and symmetrically distributed in the front-back direction of the longitudinal slide block 2. Two longitudinal limiting plates 4 are respectively set at opposite ends of two longitudinal sliding arms 3. When the two longitudinal sliding arms 3 move relative to each other, the two longitudinal limiting plates 4 can clamp the front and rear sides of the pile head. The transverse limiting plate 5 is set on the outer side of the longitudinal sliding block 2 and is used to abut against the side of the pile head facing the plate compactor 1, so that a gap is maintained between the bottom plate of the plate compactor 1 and the pile head. Adjustment component 6 connects two longitudinal sliding arms 3. Adjustment component 6 can control the two longitudinal sliding arms 3 to move synchronously towards each other or synchronously away from each other, and lock the two longitudinal limiting plates 4 in the state of clamping the pile head.

[0024] When compacting the crushed stone at the edge of the rectangular pile head, the adjusting component 6 causes the two longitudinal limiting plates 4 to move relative to each other and clamp the front and rear sides of the pile head, while the transverse limiting plate 5 abuts against the side of the pile head facing the plate tamper 1. During the compaction of the crushed stone, the guiding mechanism is fixed to the pile head and remains stationary, while the plate tamper 1 moves back and forth relative to the guiding mechanism. The transverse limiting plate 5 can block the pile head from the plate tamper 1, thus preventing the plate tamper 1 from hitting the side of the pile head and damaging it.

[0025] When compacting the crushed stone at the edge of the circular pile head, the pile head is held by two longitudinal limiting plates 4, and the transverse limiting plate 5 is pressed against the side of the pile head. The longitudinal limiting plates 4 and the transverse limiting plates 5 slide on the circumference of the pile head. The operator operates the plate tamper 1 to move around the circumference of the pile head. During this process, the transverse limiting plate 1 can prevent the plate tamper 1 from hitting the side of the pile head and damaging it.

[0026] like Figure 6 and Figure 7 As shown, in a relatively specific embodiment, the adjustment component 6 includes: There are two adjusting racks 601, which are located on opposite sides of the two longitudinal sliding arms 3. Adjusting gear 602 is rotatably mounted in longitudinal slide 2, and the upper and lower ends of adjusting gear 602 respectively mesh with two adjusting gears 602; The locking rack 603 is vertically mounted on top of the longitudinal sliding arm 3 located above; The locking tooth block 604 is fixedly installed on the top of the longitudinal slide block 2. The locking rack 603 engages the locking tooth block 604 by moving upward, thereby locking the longitudinal sliding arm 3 in the front-back direction. Adjusting screw 605 is rotatably mounted in the longitudinal sliding arm 3 located above; Adjusting thread sleeve 606 is slidably installed in the longitudinal sliding arm 3 located above, and the adjusting thread sleeve 606 is threaded on the outside of the adjusting screw 605; The upper wedge block 607 is fixedly installed at the bottom of the locking rack 603; The lower wedge block 608 is fixedly installed on the top of the adjusting thread sleeve 606. The lower wedge block 608 causes the locking rack 603 to move upward and engage with the locking rack 604 through the upper wedge block 607.

[0027] More specifically, one end of the adjusting screw 605 extends from the upper longitudinal sliding arm 3 and is connected to a knob. By rotating the knob, the knob drives the adjusting screw 605 to rotate, and the adjusting screw 605 drives the adjusting sleeve 606 to move within the upper longitudinal sliding arm 3.

[0028] When it is necessary to adjust the distance between the two longitudinal clamping plates, first turn the knob to separate the lower wedge block 608 from the bottom of the upper wedge block 607. At this time, the locking rack 603 will descend and disengage from the locking rack block 604, and then directly push the upper longitudinal sliding arm 3. During the movement of the upper longitudinal sliding arm 3, through the cooperation of the adjusting gear 602 and the adjusting rack 601, the lower longitudinal sliding arm 3 and the upper longitudinal sliding arm 3 can move synchronously towards each other or synchronously away from each other.

[0029] After the two longitudinal limiting plates 4 clamp or release the pile head, turn the knob to move the lower wedge block 608 to the bottom of the upper wedge block 607. During this process, the lower wedge block 608 pushes the upper wedge block 607 to make the locking rack 603 rise. The locking rack 603 engages with the locking block 604. At this time, the longitudinal sliding arm 3 and the longitudinal limiting plate 4 can be locked.

[0030] like Figure 3 and Figure 4 As shown, in a relatively specific embodiment, the longitudinal slide 2 includes: The lower seat 201 is slidably mounted on the upper surface of the base plate of the flat plate compactor 1; The upper seat 202 is vertically and vertically positioned directly above the lower seat 201; An elastic telescopic rod 203 is disposed between the upper seat 202 and the upper seat 202, and the upper seat 202 is supported by the elastic telescopic rod 203; The longitudinal sliding arm 3 is slidably disposed inside the upper seat 202, and the transverse limiting plate 5 is fixedly installed on the outer side of the upper seat 202.

[0031] The upper seat 202 is supported on top of the lower seat 201 by the elastic telescopic rod 203. During the operation of the plate compactor 1, the elastic telescopic rod 203 utilizes its own extension and retraction to better adapt to the vibration process of the plate compactor 1, preventing wear caused by the vertical oscillation of the longitudinal limiting plate 4 and the transverse limiting plate 5 on the pile head surface. Simultaneously, when moving the plate compactor 1 towards the pile head, and using a pry bar to lift the outer side of the bottom plate of the plate compactor 1, the elastic telescopic rod 203 compresses upwards from the bottom, making it easier for the plate compactor 1 to be lifted, thus facilitating its lateral movement.

[0032] like Figure 1 , Figure 2 and Figure 8 As shown, in a relatively specific embodiment, the guiding mechanism further includes: The connecting plate 7 is set at the opposite ends of the two longitudinal sliding arms 3, and one end of the longitudinal limiting plate 4 is rotatably installed in the connecting plate 7. The longitudinal limiting plate 4 can be stored in the area above the bottom plate of the plate compactor 1 by rotating inward. Positioning holes 8 are provided on both the inner and outer sides of the top and bottom of the connecting plate 7; The adapter hole 9 is located at one end of the longitudinal limiting plate 4 near the connecting plate 7; The positioning pin 10, by simultaneously inserting into the adapter hole 9 and two positioning holes 8 located on one side of the connecting plate 7, fixes the longitudinal limiting plate 4 in a state that can clamp the pile head or fixes the longitudinal limiting plate 4 in the area above the bottom plate housed in the plate compactor 1. The positioning hole 8 is located laterally on the side of the longitudinal sliding arm 3, and the connecting plate 7 at the end of one of the longitudinal sliding arms 3 is staggered from the other longitudinal sliding arm 3 in the height direction.

[0033] The longitudinal limiting plate 4 can be fixed in either an inward or outward position by the cooperation of the positioning hole 8, the adapter hole 9, and the positioning pin 10. When the longitudinal limiting plate 4 is in the inward position, it is stored in the area above the bottom plate of the plate compactor 1, making the plate compactor 1 more compact as a whole and preventing compaction of the crushed stone layer far from the pile head area.

[0034] More specifically, when the bottom height of the longitudinal limiting plate 4 is greater than the top height of the bottom plate of the plate compactor 1, and the longitudinal limiting plate 4 is recessed into the upper area of ​​the bottom plate of the plate compactor 1, the two longitudinal limiting plates 4 can be clamped on the front and rear sides of the cover of the plate compactor 1 respectively. With this configuration, by clamping the cover of the plate compactor 1 with the longitudinal limiting plates 4, the guiding mechanism can be fixed and prevented from sliding freely in the front and rear direction of the plate compactor 1.

[0035] like Figure 5 As shown, in a relatively specific embodiment, the lateral limiting plate 5 includes: The rigid plate body 501 is fixedly installed on the outer side surface of the longitudinal sliding seat 2; The buffer plate bodies 502 are fixedly arranged on the front and rear sides of the outer side surface of the rigid plate body 501. The buffer plate bodies 502 can be made of rubber plates, providing buffer performance while increasing friction; A plurality of rotating rods 503 are rotatably arranged in the middle of the rigid plate body 501; The outer ends of the rotating rods 503 extend out from the middle of the outer side surface of the rigid plate body 501, and the outer side surfaces of the buffer plate bodies 502 are located outside the outer surfaces of the rotating rods 503.

[0036] When ramming the gravel at the edge of the rectangular pile head, both buffer plate bodies 502 are abutted against the side surface of the pile head. At this time, the buffer plate bodies 502 have a sufficiently large contact surface with the side surface of the pile head, and when the plate compactor 1 moves back and forth, it has a better guiding effect, avoiding the plate compactor 1 from skewing and hitting the pile head.

[0037] When ramming the gravel at the edge of the circular pile head, the rotating rods 503 are abutted against the circumferential surface of the pile head. By using the rolling of the rotating rods 503 on the circumferential surface of the pile head, the friction between the guiding mechanism and the pile head is reduced, enabling the guiding mechanism to make a circular motion centered on the pile head, thereby better guiding the advancing direction of the plate compactor 1 and blocking the bottom plate of the plate compactor 1 from the pile head, avoiding the plate compactor 1 from hitting and damaging the pile head.

[0038] More specifically, the outer side surface of the rigid plate body 501 is flush with the outer side surface of the bottom plate of the plate compactor 1, and a gap is provided between the bottom of the rigid plate body 501 and the bottom plate of the plate compactor 1. This gap is adapted to the expansion and contraction of the elastic telescopic rod 203, enabling the guiding mechanism to expand and contract adaptively to the vibration excitation process of the plate compactor 1 in the height direction.

[0039] As Figure 1 and Figure 3 shown, in a relatively specific embodiment, the guiding mechanism further includes: The transverse sliding frame 11 is arranged in a "C" shape, and the bottom end of the longitudinal sliding seat 2 is slidably sleeved outside the middle side of the transverse sliding frame 11; The brackets 12 are fixedly installed at both the front and rear ends of the top of the bottom plate of the plate compactor 1, and the two ends of the transverse sliding frame 11 are respectively slidably sleeved outside the two brackets 12; The retaining wall plate 13 is fixedly installed on the outer side surface of the transverse sliding frame 11, and the retaining wall plate 13 penetrates through the outer side surface of the longitudinal sliding seat 2; The front and rear ends of the retaining wall plate 13 are respectively flush with the opposite surfaces of the two brackets 12, and the bottom of the retaining wall plate 13 is flush with the top of the bottom plate of the plate compactor 1.

[0040] The transverse slide 11 slides on the support 12, giving the longitudinal limiting plate 4 and the transverse limiting plate 5 the property of lateral displacement. Therefore, when the plate compactor 1 has a moving distance from the pile head, the transverse slide 11 can move outward on the support 12, causing the longitudinal limiting plate 4 and the transverse limiting plate 5 to move towards the pile head until the transverse limiting plate 5 fits against the side of the pile head. Then, the adjusting component 6 clamps and locks the pile head with the two longitudinal limiting plates 4. This makes it easier to fix the guide mechanism to the pile head.

[0041] The retaining plate 13 can prevent impurities from entering between the bottom plate of the plate compactor 1 and the transverse slide 11, and when the transverse slide 11 moves outward, the retaining plate 13 can push out the impurities that are laterally adhered to the upper surface of the bottom plate of the plate compactor 1.

[0042] like Figure 1 , Figure 3 , Figure 6 and Figure 9 As shown, more specifically, the guidance mechanism also includes: Fixing hole 14 is provided at the top of the inner end of bracket 12; The fixing bolts 15 are threaded and installed on the top of both ends of the transverse slide 11; When the transverse slide 11 is located at the innermost position of the plate compactor 1, the fixing bolt 15 can be inserted downward into the fixing hole 14.

[0043] In the initial state, the fixing bolt 15 is inserted into the fixing hole 14. At this time, the guide mechanism is housed on one side of the plate compactor 1 to better adapt to the compaction operation of the crushed stone layer away from the pile head area.

[0044] When it is necessary to move the transverse support 12 outward, rotate the fixing bolt 15 upward so that the bottom end of the fixing bolt 15 can be pulled out from the fixing hole 14. After moving the plate compactor 1 to the limit position in the direction of the pile head, rotate the fixing bolt 15 downward so that the fixing bolt 15 can be reinserted into the fixing hole 14, thereby effectively limiting the transverse position of the plate compactor 1 to better assist the plate compactor 1 in compacting the crushed stone in the front and back.

[0045] In a relatively specific embodiment, one guiding mechanism is provided on each side of the plate compactor 1, and the two guiding mechanisms are symmetrically distributed about the longitudinal centerline of the plate compactor 1. When it is necessary to compact the crushed stone at the edge of the pile head located on the left side of the plate compactor 1, the guiding mechanism on the left side of the plate compactor 1 can be used. Similarly, when it is necessary to compact the crushed stone at the edge of the pile head located on the right side of the plate compactor 1, the guiding mechanism on the right side of the plate compactor 1 can be used.

[0046] When using the pile-filling crushed stone slab compactor described in the above embodiment to compact the crushed stone at the edge of a circular pile head, the worker should slowly and continuously apply a slight steering force towards the pile head using the handle. This force should not be a sudden push, but a continuous guide. For bidirectional compactors, it may be necessary to simultaneously make minor adjustments to the reversing handle to change the direction of vibration and assist in lateral slippage.

[0047] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
