Description

Technical Field

[0001] This invention relates to the field of construction equipment technology, specifically to a cement-soil mixing pile internal insertion pile construction equipment that facilitates control of axial accuracy. Background Technology

[0002] Triaxial mixing piles with prestressed concrete pipe piles, also known as PCMW construction method, involves using a triaxial deep mixing machine drill bit to break up the soil to the designed depth, while simultaneously injecting cement slurry into the soil from the drill bit tip and repeatedly mixing it with the soil. To make the cement-soil mixture more uniform and liquefied, high-pressure airflow is applied to the soil layer at the drill bit. Before the cement-soil mixture hardens, prestressed concrete pipe piles are inserted, thus forming a row of underground pile walls. This method fully utilizes the water-stopping advantages of cement-soil mixing walls and the soil-retaining function of pipe piles. This method has the advantages of safety, economy, environmental protection, speed, and energy saving.

[0003] Currently, during construction, when inserting pipe piles, the pipe piles are first lifted by a crane, and then inserted into the triaxial mixing pile using their own weight. It is difficult to control the verticality of the pipe piles during the insertion process. If 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

[0004] To address the aforementioned problems, this invention provides a cement-soil mixing pile internal pipe pile construction device that facilitates control of axial accuracy.

[0005] The technical solution of this invention is: a cement-soil mixing pile internal pipe pile construction device that facilitates control of axial accuracy, comprising a base platform and a rotating frame rotatably mounted on the base platform; a rotating cylinder is provided inside the rotating end of the rotating frame, and a lifting cylinder is slidably provided inside the swinging end of the rotating frame; clamping mechanisms are provided on the side walls of both the rotating cylinder and the lifting cylinder, and a distance measuring sensor for measuring the distance between the inner wall of the rotating cylinder and the pipe pile is provided on the side wall of the rotating cylinder; a notch for the pipe pile to pass through is provided on the base platform at the corresponding position of the rotating cylinder; the clamping mechanism includes multiple hydraulic rods and fixed cylinders corresponding to each hydraulic rod; a movable rod is slidably sealed inside the fixed cylinder; the hydraulic rods pass through the side walls of the rotating cylinder and the lifting cylinder and are provided with arc-shaped clamps; both sides of the arc-shaped clamps are slidably provided with purge blocks connected to them by springs; multiple purge blocks are provided on the side walls of the purge blocks for adjusting the arc-shaped clamps. The purging port has an air chamber within an arc-shaped clamp. The purging block has a gas channel that connects to the air chamber via its sliding mechanism. One end of the movable rod passes through the side wall of the tilting cylinder and the lifting cylinder and is equipped with a friction wheel for contacting the pipe pile. The movable rod also has a groove, within which a rotating wheel that is driven by a beaded transmission rope is mounted. The beaded transmission rope has several fixed beads. The inner wall of the friction wheel has a lubricant bladder that cooperates with the fixed beads for compression. The lubricant bladder has a liquid pipe that connects to the rotating shaft of the friction wheel. The groove contains a second air bladder that communicates with the air chamber. One end of the second air bladder is fixedly connected to the inner wall of the groove, and the other end of the second air bladder has a compression plate that is slidably connected to the groove. The compression plate has a slot for the beaded transmission rope to pass through, and two locking blocks connected to the compression plate via springs are slidably mounted on both sides of the slot.

[0006] Explanation: The above equipment places the pipe pile into the lifting cylinder and the tilting cylinder, fixes the pipe pile by the clamping mechanism, and then rotates the tilting frame to flip the pipe pile from horizontal to vertical. The lifting cylinder drives the pipe pile to descend, allowing it to be inserted into the cement-soil slurry. During the insertion process, the distance sensor can measure the verticality of the pipe pile in real time. If the pipe pile position deviates, the position of the pipe pile can be adjusted by the arc-shaped clamp in the tilting cylinder to ensure the axial accuracy of the pipe pile. When the pipe pile descends, it will drive the friction wheel to rotate, causing the beaded transmission rope to intermittently pull the extrusion plate to inflate the air chamber. When the clamping mechanism is released, the gas in the air chamber can be released through the blowing block to blow away the arc-shaped clamp, preventing a large amount of dust from adhering to the arc-shaped clamp and affecting the adjustment accuracy of the pipe pile position.

[0007] Furthermore, the arc-shaped clamping piece consists of a fixed piece and multiple movable pieces rotatably disposed on both sides of the fixed piece, and two adjacent movable pieces are rotatably connected. The fixed piece and the movable pieces, as well as two adjacent movable pieces, are connected by torsion springs. Both the fixed piece and the movable pieces are provided with air chambers, and both sides of the fixed piece and the movable pieces are provided with purge blocks that slide in communication with the corresponding air chambers.

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

[0009] Furthermore, the fixed plate has a liquid cavity inside and an oil spray nozzle on its inner wall. The fixed plate has a liquid bladder for connecting the liquid cavity and the oil spray nozzle. The rotating shaft of the movable plate has a pressure plate that squeezes the liquid bladder by rotating the movable plate.

[0010] Explanation: When the arc-shaped clamp is in close contact with the pipe pile, the movable plate will rotate. The rotating shaft of the movable plate will drive the pressure plate to squeeze the liquid bladder, so that the lubricant in the liquid bladder 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, thus reducing the wear of the arc-shaped clamp.

[0011] Furthermore, each of the ranging sensors is provided with a reciprocating lead screw on one side, one end of which extends into the groove of the movable rod on the same side, and the beaded transmission rope is wound around the reciprocating lead screw. An arc-shaped cleaning plate is sleeved on the reciprocating lead screw to clean the ranging sensor by rotating it.

[0012] Note: During the descent of the pipe pile, the friction wheel drives the reciprocating screw to rotate via the beaded transmission rope, causing the arc-shaped cleaning plate to move back and forth to clean the distance sensor. This prevents dust from 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, one end of the reciprocating lead screw is provided with an annular groove, the bead-shaped transmission rope is located in the annular groove, and the annular grooves of the rotating wheel, the friction wheel, and the reciprocating lead screw are all provided with grooves that cooperate with the fixed beads.

[0014] Note: The beaded drive rope is located in the annular groove, which can prevent the reciprocating screw from disengaging from the beaded drive rope. The groove can increase the friction between the reciprocating screw and the beaded drive rope, thereby improving the transmission efficiency between them.

[0015] Furthermore, the settling tank is provided with a storage chamber communicating with the second airbag, the arc-shaped cleaning plate is provided with multiple spray nozzles for spraying cleaning fluid, the side wall of the storage chamber is provided with a fixing block communicating with the multiple spray nozzles, the fixing block is provided with a slide bar that controls the release of cleaning fluid by sliding, and one end of the reciprocating screw is provided with a protrusion that pushes one end of the slide bar to slide by rotating, and the other end of the slide bar is connected to the fixing block by a tension spring.

[0016] Explanation: When the reciprocating screw rotates, the fixed block intermittently squeezes the slide bar, causing the slide bar to slide back and forth to release the cleaning fluid. Since the fixed bead triggers the second airbag at a higher frequency than the slide bar, the pressure inside the storage chamber is sufficient, allowing the cleaning fluid to be released onto the distance sensor through the spray nozzle, thus ensuring the measurement accuracy of the distance sensor.

[0017] Furthermore, the rotating end of the flipping frame is fixedly provided with a transverse sleeve, and the base is provided with a telescopic rod 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 prevent the flipping frame from shaking and ensure the axial accuracy of the pipe pile descent.

[0019] Furthermore, the base is equipped with multiple lifting outriggers.

[0020] Note: The lifting outriggers allow for adjustable base height, enabling the equipment to be adjusted to suit different working environments.

[0021] The beneficial effects of this invention are:

[0022] (1) The device of the present invention fixes the pipe pile by clamping mechanism, flips the pipe pile from the horizontal to the vertical by flipping 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 by the arc-shaped clamp to ensure the axial accuracy of the pipe pile. At the same time, when the pipe pile is lowered, it will drive the friction wheel to rotate, so that the second air bag will be inflated into the air chamber, and the blowing block will blow the arc-shaped clamp to avoid a large amount of dust adhering on the arc-shaped clamp, which would affect the adjustment accuracy of the position of the pipe pile.

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

[0038] To further illustrate the methods and effects of this invention, the technical solution of this invention will be clearly and completely described below in conjunction with experiments.

[0039] Example 1: As Figure 1 , Figure 2As shown, a cement-soil mixing pile internal pipe pile construction device that facilitates control of axial accuracy includes a base 1 and a rotating frame 2 rotatably mounted on the base 1. The rotating end of the rotating frame 2 is provided with a rotating cylinder 3, and the swing end of the rotating frame 2 is provided with a lifting cylinder 4. Both the rotating cylinder 3 and the lifting cylinder 4 are provided with clamping mechanisms on their side walls. The side wall of the rotating cylinder 3 is provided with two distance measuring sensors 31 for measuring the distance between the inner wall of the rotating cylinder 3 and the pipe pile. The distance between the two distance measuring sensors 31 is 90°. The distance measuring sensors 31 are commercially available laser distance measuring sensors. The base 1 located at the corresponding position of the rotating cylinder 3 is provided with a notch for the pipe pile to pass through.

[0040] like Figure 3 As shown, the clamping mechanism includes four hydraulic rods 38 and fixed cylinders 32 corresponding to each hydraulic rod 38. A movable rod 33 is slidably sealed inside the fixed cylinder 32. The hydraulic rods 38 pass through the side walls of the tilting cylinder 3 and the lifting cylinder 4 and are equipped with arc-shaped clamping pieces, such as... Figure 4 As shown, both sides of the arc-shaped clamp are slidably provided with blowing blocks 39 connected to them by springs. The blowing blocks 39 are slidably connected to the sliding grooves on the arc-shaped clamp via sliders provided on them. The springs are set in the sliding grooves. The side walls of the blowing blocks 39 are provided with six air ports 391 for blowing the arc-shaped clamp. Figure 5 As shown, the arc-shaped clamp is provided with an air cavity, and the purge block 39 is provided with a gas channel that communicates with the air cavity by sliding.

[0041] like Figure 6 , Figure 7 As shown, the lower end of the movable rod 33 passes through the side wall of the tilting cylinder 3 and the lifting cylinder 4 and is rotatably equipped with a friction wheel 35 for contacting the pipe pile. The movable rod 33 is provided with a groove 331, and a rotating wheel 36, which is driven by the friction wheel 35 via a beaded transmission rope 37, is rotatably mounted within the groove 331. The beaded transmission rope 37 has several fixed beads 371. Figure 8 As shown, the inner wall of the friction wheel 35 is provided with a lubricant bladder 351 that cooperates with the fixed bead 371 to compress. The lubricant bladder 351 is provided with a liquid pipe that is connected to the rotating shaft of the friction wheel 35. The liquid pipe is provided with a one-way valve that connects one-way from the lubricant bladder 351 to the liquid pipe. The inner wall of the friction wheel 35 is provided with a lubricant chamber that supplies liquid to the lubricant bladder 351. The lubricant chamber and the lubricant bladder 351 are connected by a pipe. The pipe is provided with a one-way valve that connects one-way from the lubricant chamber to the lubricant bladder 351.

[0042] like Figure 9As shown, a second airbag 335 is provided in the settling tank 331 and is connected to the air chamber through a pipe. Both the air inlet and the air outlet of the second airbag 335 are provided with one-way valves. The one-way valve at the air inlet of the second airbag 335 is connected to the second airbag 335 in one direction from the outside. The one-way valve at the air outlet of the second airbag 335 is connected to the air chamber in one direction from the second airbag 335. The right end of the second airbag 335 is fixedly connected to the mounting plate provided on the inner wall of the settling tank 331. The left end of the second airbag 335 is provided with a compression plate 336 that is slidably connected to the settling tank 331. The compression plate 336 is provided with a slot for the bead-shaped transmission rope 37 to pass through. On both sides of the slot, there are sliding blocks 337 connected to the compression plate 336 through springs.

[0043] Each of the ranging sensors 31 is provided with a reciprocating lead screw 34 on the left side. The left end of the reciprocating lead screw 34 extends into the groove 331 of the movable rod 33 on the same side, and the bead-shaped transmission rope 37 is wound around the reciprocating lead screw 34. An arc-shaped cleaning plate 341 is sleeved on the reciprocating lead screw 34 to clean the ranging sensor 31 by rotating it.

[0044] The left end of the reciprocating screw 34 is provided with an annular groove, the bead-shaped transmission rope 37 is located in the annular groove, and the annular groove of the wheel 36, the annular groove of the friction wheel 35, and the annular groove of the reciprocating screw 34 are all provided with grooves that cooperate with the fixed bead 371.

[0045] The rotating end of the flipping frame 2 is fixedly provided with a transverse sleeve 24. The base 1 is provided with a telescopic rod 14 for docking with the transverse sleeve 24 after it is flipped. The telescopic rod 14 is a commercially available pneumatic rod. The base 1 is provided with four lifting legs 11. The lifting legs 11 are existing technology products.

[0046] The tilting frame 2 includes two rotating plates 21 respectively disposed on the front and rear sides of the base 1; the base 1 has two connecting plates that are rotatably connected to the rotating plates 21 in a one-to-one correspondence, the rotating shafts of the two rotating plates 21 pass through the corresponding connecting plates and are fixedly connected to the tilting cylinder 3, and the base 1 is provided with a driving device for driving the rotating plates 21 to tilt.

[0047] The drive device includes a shaft 12 horizontally disposed below the tilting frame 2 and rotatably connected to the base 1, and a second connecting rod 22 respectively hinged to the rotating plate 21. The second connecting rod 22 is hinged to the rotating plate 21 through a rotating shaft provided thereon. A first connecting rod 13 is fixedly sleeved on the shaft 12 and hinged to the second connecting rod 22. The first connecting rod 13 is hinged to the second connecting rod 22 through a rotating shaft provided thereon. The front end of the shaft 12 is provided with a motor for driving its rotation. The motor is a commercially available product.

[0048] Two lead screws 23 are rotatably mounted on the two rotating plates 21 respectively; both lead screws 23 are threadedly connected to the lifting cylinder 4. The lifting cylinder 4 is threadedly connected to the lead screws 23 through threaded blocks on its front and rear sides respectively. Both lead screws 23 are equipped with motors on their left ends. The motors are commercially available products. The tilting cylinder 3 is equipped with an air pump for charging and decharging air into the fixed cylinder 32.

[0049] The working principle of the above equipment is as follows: In the initial state, the tilting frame 2 is in a horizontal position. The pipe pile is horizontally placed into the tilting cylinder 3 and the lifting cylinder 4. 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 in complete contact with the pipe pile, the blowing block 39 will slide under the action of the pipe pile. At this time, the air chamber cannot be connected with the air blowing port 391. Then, the motor drives the shaft 12 to rotate. The shaft 12 drives the tilting frame 2 to rotate around the rotating shaft as the center through the first connecting rod 13 and the second connecting rod 22 until the tilting frame 2 is tilted to the vertical position. At this time, the pipe pile is in a vertical position. At this time, the hydraulic rod 38 in the tilting cylinder 3 is shortened by 5mm. At this time, the blowing block 39 cannot be completely reset. The air pump inflates the fixed cylinder 32, so that the movable rod 33 moves downward until the friction wheel 35 contacts the outer wall of the pipe pile. Then, the motor drives the lead screw 23 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 tilting cylinder 3 is adjusted by extending or shortening the hydraulic rod 38 inside the tilting cylinder 3 when the pipe pile deviates from the vertical direction. This adjusts the position of the pipe pile and ensures its axial accuracy. Simultaneously, the descent of the pipe pile drives the friction wheel 35 to rotate. The friction wheel 35, via the beaded transmission rope 37, drives the reciprocating screw 34 to rotate, causing the arc-shaped cleaning plate 341 to reciprocate on the reciprocating screw 34 to clean the ranging sensor 31 and prevent it from becoming dusty. The shielding is in place, and the fixed bead 371 on the beaded transmission rope 37 can cooperate with the clamping block 337 to intermittently pull the extrusion plate 336, causing the second airbag 335 to inflate into the air chamber. The fixed bead 371 can also intermittently squeeze the lubricant bladder 351, causing the lubricant bladder 351 to add lubricant to the rotating shaft of the friction wheel 35, thereby reducing the resistance of the rotating shaft of the friction wheel. After the pipe pile is inserted, the purging block 39 is fully reset. At this time, the air chamber is connected to the air blowing port 391, and the purging block 39 will purify the arc-shaped clamping plate.

[0050] Example 2: Figure 10 , Figure 11As shown, this embodiment is basically the same as embodiment 1, except that the arc-shaped clamping piece is composed of a fixed piece 381 and two movable pieces 382 respectively rotatably disposed on both sides of the fixed piece 381. The fixed piece 381 and the movable pieces 382 are connected by a torsion spring. Both the fixed piece 381 and the movable pieces 382 are provided with air chambers. Both sides of the fixed piece 381 and both sides of the movable pieces 382 are provided with purge blocks 39 that slide in communication with the corresponding air chambers. The inner wall of the fixed piece 381 is provided with a first airbag 386. The fixed piece 381 is provided with a pneumatic rod 387 that restricts the rotation of the movable pieces 382 by inflating and elongating. The first airbag 386 is connected to the pneumatic rod 387.

[0051] The fixed plate 381 located inside the rotating cylinder 3 has a liquid chamber, and the inner wall of the fixed plate 381 has a spray nozzle 383. The fixed plate 381 has a liquid bladder 384 for connecting the liquid chamber and the spray nozzle 383. Both the inlet and outlet of the liquid bladder 384 are equipped with one-way valves. The one-way valve at the inlet connects one-way from the liquid chamber to the liquid bladder 384, and the one-way valve at the outlet connects one-way from the liquid bladder 384 to the spray nozzle 383. The rotating shaft of the movable plate 382 is equipped with a pressure plate 385 that uses the rotation of the movable plate 382 to squeeze the liquid bladder 384.

[0052] The working principle of the above-mentioned arc-shaped clamp is as follows: After the arc-shaped clamp is in complete contact with the pipe pile, the movable plate 382 will rotate, so that the arc-shaped clamp adjusts its curvature and makes complete contact with the pipe pile. At the same time, the first air bladder 386 will contract, so that the air pressure rod 387 will extend to restrict the rotation of the movable plate 382. Meanwhile, when the movable plate 382 inside the flipping cylinder 3 rotates, it will squeeze the liquid bladder 384, so that the pressure plate 385 squeezes the liquid bladder 384, so that the lubricant in the liquid bladder 384 is released through the spray nozzle 383 to the fixed plate 381 and the pipe pile, so that the friction force on the arc-shaped clamp is reduced when the pipe pile descends.

[0053] Example 3: As Figure 12 , Figure 13 As shown, this embodiment is basically the same as embodiment 1, except that the sedimentation tank 331 is provided with a storage chamber 332 that communicates with the air outlet of the second airbag 335, the arc-shaped cleaning plate 341 is provided with five spray nozzles for spraying cleaning fluid, the side wall of the storage chamber 332 is provided with a fixing block 333 that communicates with the five spray nozzles, the fixing block 333 is provided with a sliding strip 334 that controls the release of cleaning fluid by sliding, the fixing block 333 is provided with a release hole for releasing cleaning fluid, the release hole is connected to the spray nozzle through a telescopic hose, the sliding strip 334 is provided with a docking hole that connects with the release hole by sliding, and the rear end of the reciprocating screw 34 is provided with a protrusion 342 that pushes the left end of the sliding strip 334 to slide by rotating, and the right end of the sliding strip 334 is connected to the fixing block 333 by a tension spring.

[0054] The working principle of the storage chamber 332 is as follows: During the rotation of the reciprocating screw 34 driven by the bead-shaped transmission rope 37, the second airbag 335 can inflate the storage chamber 332. 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 align with the release hole, allowing the cleaning fluid to pass through the release hole and the telescopic hose and be sprayed from the spray nozzle onto the lens of the ranging sensor 31, thereby improving the cleaning effect of the arc-shaped cleaning plate 341.
