Description

Technical Field

[0001] The invention relates to the technical field of construction equipment, and in particular to a cement-soil mixing pile inner pipe pile construction equipment which is convenient for controlling axial precision. Background Art

[0002] The PCMW method is to use the drill bit of a three-axis deep mixer to cut the soil to the designed depth, and at the same time, pour cement slurry into the soil from the front end of the drill bit and repeatedly mix it with the soil. In order to make the cement soil mixture more evenly liquefied, a high-pressure airflow is also used to sweep the soil layer at the drill bit. Before the cement soil is hardened, the prestressed pipe piles are inserted, thus forming a row of underground pile walls, which gives full play to the water-stopping advantages of the cement soil mixing wall and the retaining effect of the pipe piles. This method has the advantages of safety, economy, environmental protection, speed and energy saving.

[0003] During current construction, when inserting pipe piles, the pipe piles are first lifted by a crane, and then inserted into the three-axis mixing piles using their own weight. During the insertion process of the pipe piles, it is difficult to control the verticality. Once the pipe piles tilt significantly, they need to be pulled out and reinserted, which results in low construction efficiency and difficulty in ensuring construction quality. Summary of the invention

[0006] Description: The above equipment puts the pipe pile into the lifting cylinder and the turning cylinder, fixes the pipe pile through the clamping mechanism, and then turns the pipe pile from horizontal to vertical by rotating the turning frame, and drives the pipe pile to descend through the lifting cylinder, so that the pipe pile is inserted into the cement soil slurry, and the distance sensor can measure the verticality of the pipe pile in real time during the insertion of the pipe pile. When the position of the pipe pile is offset, the position of the pipe pile can be adjusted by the arc-shaped clamp in the turning cylinder to ensure the axial accuracy of the pipe pile, and when the pipe pile descends, it will drive the friction wheel to rotate, so that the bead-shaped transmission rope intermittently pulls the extrusion plate to inflate the air cavity. When the clamping mechanism is released, the gas in the air cavity can be released through the purge block to purge the arc-shaped clamp to avoid a large amount of dust adhering to the arc-shaped clamp, which causes the arc-shaped clamp to affect the adjustment accuracy of the pipe pile position.

[0007] Furthermore, the arc-shaped clamp is composed of a fixed plate and a plurality of movable plates rotatably arranged on both sides of the fixed plate, and two adjacent movable plates are rotatably connected to each other, the fixed plate and the movable plate, and two adjacent movable plates are connected by torsion springs, and air cavities are provided in the fixed plate and the movable plate, and purge blocks slidably connected to the corresponding air cavities are provided on both sides of the fixed plate and both sides of the movable plate.

[0008] Note: The arc-shaped clamping piece of the above structure can adjust its own curvature according to the pipe piles of different diameters, so as to ensure that the clamping mechanism can effectively clamp pipe piles of various specifications.

[0009] Furthermore, a liquid cavity is provided in the fixed plate, and an oil spray port is provided on the inner wall of the fixed plate, a liquid bag for connecting the liquid cavity and the oil spray port is provided on the fixed plate, and a pressing plate for rotating and squeezing the liquid bag by the movable plate is provided on the rotating shaft of the movable plate.

[0010] Description: When the arc-shaped clamp is in close contact with the pipe pile, the movable piece will rotate, and the rotating shaft of the movable piece will drive the pressing piece to squeeze the liquid bag, so that the lubricant in the liquid bag is sprayed onto the pipe pile and the arc-shaped clamp. During the descent of the pipe pile, the friction between the pipe pile and the arc-shaped clamp can be reduced, thereby reducing the wear of the arc-shaped clamp.

[0011] Furthermore, a reciprocating screw is provided on one side of the distance measuring sensor, one end of the reciprocating screw extends into the sink groove of the movable rod on the same side, and the bead-shaped transmission rope is wound around the reciprocating screw, and an arc-shaped cleaning sheet is sleeved on the reciprocating screw for cleaning the distance measuring sensor by rotating it.

[0012] Note: During the lowering process of the pipe pile, the friction wheel will drive the reciprocating screw to rotate through the bead-shaped transmission rope, so that the arc-shaped cleaning piece will move back and forth to clean the distance sensor, avoiding dust covering the distance sensor lens and affecting the measurement accuracy of the distance sensor, further ensuring the axial accuracy of the pipe pile.

[0013] Furthermore, an annular groove is provided at one end of the reciprocating screw rod, the bead-shaped transmission rope is located in the annular groove, and the annular groove of the rotating wheel, the annular groove of the friction wheel, and the annular groove of the reciprocating screw rod are all provided with grooves that cooperate with the fixing beads.

[0014] Description: The bead-type transmission rope is located in the annular groove, which can prevent the reciprocating screw rod and the bead-type transmission rope from detaching. The groove can increase the friction between the reciprocating screw rod and the bead-type transmission rope, and improve the transmission efficiency between the reciprocating screw rod and the bead-type transmission rope.

[0015] Furthermore, a storage bin connected to the second airbag is provided in the sink, a plurality of spraying ports for spraying cleaning liquid is provided on the arc-shaped cleaning sheet, a fixed block connected to the plurality of spraying ports is provided on the side wall of the storage bin, a sliding bar for controlling the release of cleaning liquid by its sliding is slidably provided on the fixed block, and a protrusion for driving one end of the sliding bar to slide by its rotation is provided at one end of the reciprocating screw rod, and the other end of the sliding bar is connected to the fixed block by a tension spring.

[0016] Description: When the reciprocating screw rotates, the fixed block can intermittently squeeze the slider, causing the slider to slide back and forth to release the cleaning liquid. Since the frequency of the fixed bead triggering the second airbag is greater than the triggering frequency of the slider, it can ensure that the pressure in the storage bin is sufficient, so that the cleaning liquid can be released to the distance sensor through the spray port to ensure the measurement accuracy of the distance sensor.

[0017] Furthermore, a transverse sleeve is fixedly provided at the rotating end of the flip frame, and a telescopic rod is provided on the base for docking with the transverse sleeve after the transverse sleeve is flipped.

[0018] Note: After flipping to the vertical position, the telescopic rod can be extended to connect with the horizontal sleeve to avoid shaking of the flip frame and ensure the axial accuracy of the pile descent.

[0019] Furthermore, the base is provided with a plurality of lifting legs.

[0020] Description: The lifting legs can adjust the height of the base, so that the height of the equipment can be adjusted according to different working environments.

[0021] The beneficial effects of the present invention are:

[0022] (1) The device of the present invention fixes the pipe pile through a clamping mechanism, and flips the pipe pile from horizontal to vertical through a flip frame, so that the pipe pile is lowered and inserted into the cement soil slurry. During the insertion of the pipe pile, the distance sensor can measure the verticality of the pipe pile in real time, and adjust the position of the pipe pile through the arc-shaped clamp to ensure the axial accuracy of the pipe pile. At the same time, when the pipe pile descends, it will drive the friction wheel to rotate, so that the second airbag is inflated into the air cavity, and the purge block is used to purge the arc-shaped clamp to avoid a large amount of dust adhering to the arc-shaped clamp, which will affect the adjustment accuracy of the pipe pile position.

[0023] (2) The friction wheel of the present invention can drive the reciprocating screw to rotate through the bead-shaped transmission rope, so that the arc-shaped cleaning sheet can move back and forth to clean the distance sensor, thereby preventing dust from covering the distance sensor lens and affecting the measurement accuracy of the distance sensor, thereby further ensuring the axial accuracy of the pipe pile.

[0045] A transverse sleeve 24 is fixedly provided at the rotating end of the turning frame 2, and a telescopic rod 14 is provided on the base 1 for docking with the transverse sleeve 24 after the transverse sleeve 24 is turned over. The telescopic rod 14 adopts a commercially available pneumatic rod; four lifting legs 11 are provided on the base 1, and the lifting legs 11 adopt existing technology products;

[0047] The driving device includes a shaft rod 12 which is transversely arranged below the flip frame 2 and is rotatably connected to the base 1, and a second connecting rod 22 which is respectively hinged on the rotating plate 21, and the second connecting rod 22 is hinged to the rotating plate 21 through a rotating shaft provided thereon; a first connecting rod 13 which is hinged to the second connecting rod 22 is fixedly sleeved on the shaft rod 12, and the first connecting rod 13 is hinged to the second connecting rod 22 through a rotating shaft provided thereon, and a motor for driving the shaft rod 12 to rotate is provided at the front end thereof, and the motor adopts a commercially available product;

[0048] Two screw rods 23 are respectively rotatably provided on the two rotating plates 21; the two screw rods 23 are both threadedly connected to the lifting cylinder 4, and the lifting cylinder 4 is threadedly connected to the screw rods 23 through threaded blocks respectively provided on its front and rear sides, and motors are provided at the left ends of the two screw rods 23, and the motors are commercially available products. An air pump for inflating and deflating air into the fixed cylinder 32 is provided on the flip cylinder 3.

[0049] The working principle of the above equipment is as follows: in the initial state, the turning frame 2 is in a horizontal state, and the pipe pile is placed horizontally in the turning cylinder 3 and the lifting cylinder 4, and the clamping mechanism is driven to extend the hydraulic rod 38, so that the arc-shaped clamping piece clamps the pipe pile. After the arc-shaped clamping piece is fully in contact with the pipe pile, the purge block 39 will slide under the action of the pipe pile. At this time, the air cavity cannot be connected with the blowing port 391, and then the shaft rod 12 is driven by the motor to rotate, and the shaft rod 12 drives the turning frame 2 to rotate with the rotating shaft as the center through the first connecting rod 13 and the second connecting rod 22 until the turning frame 2 is turned to a vertical state. At this time, the pipe pile is in a vertical state. At this time, the hydraulic rod 38 in the turning cylinder 3 is controlled to be shortened by 5mm. At this time, the purge block 39 cannot be completely reset, and the fixed cylinder 32 is inflated by the air pump to make the movable rod 33 move downward until the friction wheel 35 contacts the outer wall of the pipe pile, and then the screw rod 23 is driven by the motor to rotate, so that the lifting cylinder 4 drives the pipe pile to descend. During the descent of the pipe pile, the two distance sensors 31 can measure in real time The distance between the pipe pile and the inner wall of the turning cylinder 3 is such that when the pipe pile deviates from the vertical direction, the hydraulic rod 38 in the turning cylinder 3 can be controlled to extend or shorten to adjust the position of the pipe pile and ensure the axial accuracy of the pipe pile. At the same time, when the pipe pile descends, the friction wheel 35 is driven to rotate. The friction wheel 35 can drive the reciprocating screw rod 34 to rotate through the bead-shaped transmission rope 37, so that the arc-shaped cleaning piece 341 can reciprocate on the reciprocating screw rod 34 to clean the distance sensor 31 and prevent the distance sensor 31 from being contaminated by dust. Block, and at the same time, the fixed bead 371 on the bead-shaped transmission rope 37 can cooperate with the card block 337 to intermittently pull the extrusion plate 336 to inflate the second air bag 335 into the air cavity, and the fixed bead 371 can intermittently squeeze the lubricant bag 351 to make the lubricant bag 351 add lubricant to the rotating shaft of the friction wheel 35 to reduce the resistance of the rotating shaft of the friction wheel. After the insertion of the pipe pile is completed, the purge block 39 is completely reset. At this time, the air cavity is connected to the blowing port 391, and the purge block 39 will purge the arc-shaped clip.

[0050] Example 2: Fig.10 , Fig.11As shown, this embodiment is basically the same as the embodiment 1, except that the arc-shaped clip is composed of a fixed sheet 381 and two movable sheets 382 rotatably arranged on both sides of the fixed sheet 381, and the fixed sheet 381 and the movable sheet 382 are connected by a torsion spring, and air cavities are arranged in the fixed sheet 381 and the movable sheet 382, ​​and purge blocks 39 that are slidably connected to the corresponding air cavities are arranged on both sides of the fixed sheet 381 and the movable sheet 382; a first air bag 386 is arranged on the inner wall of the fixed sheet 381, and the fixed sheet 381 is provided with a pneumatic rod 387 that limits the rotation of the movable sheet 382 by inflation and extension, and the first air bag 386 is connected to the pneumatic rod 387;

[0051] A liquid cavity is provided in the fixed plate 381 located in the flip cylinder 3, and a liquid spraying port 383 is provided on the inner wall of the fixed plate 381. A liquid capsule 384 for connecting the liquid cavity and the liquid spraying port 383 is provided on the fixed plate 381. A one-way valve is provided in the liquid inlet and the liquid outlet of the liquid capsule 384. The one-way valve at the liquid inlet is connected from the liquid cavity to the liquid capsule 384 in a one-way direction, and the one-way valve at the liquid outlet is connected from the liquid capsule 384 to the liquid spraying port 383 in a one-way direction. A pressing plate 385 for rotating and squeezing the liquid capsule 384 by utilizing the movable plate 382 is provided on the rotating shaft of the movable plate 382.

[0052] The working principle of the above-mentioned arc-shaped clamp is as follows: after the arc-shaped clamp is in full contact with the pipe pile, the movable piece 382 will rotate so that the arc-shaped clamp adjusts the arc and is in full contact with the pipe pile, and at the same time, the first air bag 386 will contract, so that the air pressure rod 387 will extend to limit the rotation of the movable piece 382, ​​and at the same time, the movable piece 382 in the flip cylinder 3 will squeeze the liquid bag 384 when it rotates, so that the pressing piece 385 squeezes the liquid bag 384, and the lubricant in the liquid bag 384 is released to the fixed piece 381 and the pipe pile through the liquid spray port 383, so that the friction force of the pipe pile on the arc-shaped clamp is reduced when the pipe pile descends.

[0053] Example 3: Fig.12 , Fig.13 As shown, this embodiment is basically the same as embodiment 1, except that a storage bin 332 connected to the air outlet of the second airbag 335 is provided in the sink 331, five spraying ports for spraying cleaning liquid are provided on the arc-shaped cleaning sheet 341, a fixed block 333 connected to the five spraying ports is provided on the side wall of the storage bin 332, a slide bar 334 for controlling the release of the cleaning liquid by sliding is slidably provided on the fixed block 333, a release hole for releasing the cleaning liquid is provided on the fixed block 333, the release hole is connected to the spraying port through a telescopic hose, a docking hole for docking with the release hole by sliding is provided on the slide bar 334, and a protrusion 342 for driving the left end of the slide bar 334 to slide by rotating is provided at the rear end of the reciprocating screw rod 34, and the right end of the slide bar 334 is connected to the fixed block 333 by a tension spring.

[0054] The working principle of the above-mentioned storage bin 332 is as follows: when the bead-shaped transmission rope 37 drives the reciprocating screw 34 to rotate, the second airbag 335 can be inflated into the storage bin 332, and when the reciprocating screw 34 rotates, the protrusion 342 will intermittently squeeze the slide bar 334, causing the slide bar 334 to slide to the right. When the slide bar 334 slides to the right, the docking hole will be aligned with the release hole, so that the cleaning liquid passes through the release hole and the telescopic hose and is sprayed from the spray port onto the lens of the ranging sensor 31, so as to improve the cleaning effect of the arc-shaped cleaning sheet 341.
