Description

Technical Field

[0001] This invention relates to the field of pipe pile retrieval technology, and in particular to a polymer cable rapid pile retrieval tool and construction method. Background Technology

[0002] In engineering fields such as offshore wind power, bridge foundation construction, and port construction, pipe piles are widely used as a major foundation structure. They are usually manufactured in a prefabrication yard and then transported to the construction site for pile driving. Due to the large size and heavy weight of pipe piles, they need to be quickly and safely erected from a horizontal position using lifting equipment during construction. This process is called pile removal.

[0003] Regarding the lifting and turning device for offshore wind power pipe piles disclosed in patent publication number "CN118850955B", the first control block pushes and controls the first trapezoidal plate. At this time, the first trapezoidal plate moves horizontally until the first bonding plate is tightly attached to the inner wall of the pipe pile. After the control insert plate passes through the T-shaped plate, the stability of the first control block can be improved, thereby reducing the pressure of the electric hydraulic rod to keep the bonding plate tightly attached to the inner wall of the pipe pile. This allows the pipe pile to maintain a stable posture during the turning and lifting process to a certain extent.

[0004] However, in actual use, due to the continuous wind force in the marine environment, the pipe pile will be subjected to significant lateral thrust during the flipping process, causing the pipe pile to swing periodically. This swing will be transmitted to the clamping mechanism through the lifting device, resulting in repeated squeezing and loosening between the bonding plate and the inner wall of the pipe pile, thereby causing fluctuations in the clamping force and increasing safety hazards.

[0005] Accordingly, this application proposes a rapid pile-taking tool and construction method using polymer cables. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid pile-taking tool and construction method using polymer cables.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A polymer cable rapid pile extraction tool includes a pipe pile, lifting lug 1, lifting lug 2, lifting lug 3, lifting lug 4, lifting lug 5, four stabilizing components, two rope pressing and limiting components, and two wind-resistant components. The first and second lifting lugs are fixedly installed side by side on the pipe pile, the fourth and fifth lifting lugs are fixedly installed side by side on the pipe pile, and the third lifting lug is fixedly installed below the pipe pile and between the first and second lifting lugs. Each of the first, second, fourth, and fifth lifting lugs has an inner groove and two annular holes. A crossbeam is provided above the pipe pile, and two hangers are fixedly installed on the crossbeam. Each of the two hangers has a hook, and a cable is hung on each of the two hooks. The cables on the first and second lifting lugs are connected in series through the hooks, and the cables on the fourth and fifth lifting lugs are connected in series through the hooks. A swivel is fixedly installed at one end of each cable. The stabilizing component is used to maintain stability when the pipe pile is erected; The cable clamping and limiting component can prevent excess cable from drooping; The wind-resistant components are used to reduce the impact of wind on the pile-lifting operation.

[0008] Preferably, the stabilizing component includes a slider, a plurality of first balls, two semicircular rings, an arc groove, and a lead screw; the slider is fixedly connected to the cable ring, the first balls are movably connected to the inner groove, the arc groove is provided on the slider, and the two semicircular rings are slidably connected to the slider respectively.

[0009] Preferably, the two semicircular rings are slidably connected in the two annular holes, the lead screw is slidably connected in the two annular holes, the slider is slidably connected in the inner groove, the arc groove is attached to the first ball, and a torsion handle is provided at one end of the lead screw.

[0010] Preferably, the rope-pressing and limiting assembly includes a mounting sleeve, a pulley, two connecting arms, two extending arms, two one-way stops, and several second ball bearings; the mounting sleeve is fixedly mounted on the cable, the pulley is attached to the cable, and the two extending arms are respectively fixedly connected to both sides of the mounting sleeve.

[0011] Preferably, one end of each of the two connecting arms is rotatably connected to the mounting sleeve, and the other end is rotatably connected to the pulley. A damping shaft is provided at the connection between the connecting arm and the mounting sleeve. The one-way stop is rotatably connected to one end of the extension arm, and several second balls are movably connected to one end of the one-way stop.

[0012] Preferably, the wind-resistant component includes two clamping rings, a mounting block, a square sleeve, an arc cylinder, a bent column, and two springs. The clamping rings are mounted on the pipe pile, and the two clamping rings are rotatably connected to the mounting block. One end of the square sleeve is rotatably connected to the mounting block.

[0013] Preferably, the arc cylinder is fixedly connected to one end of the square sleeve, the curved column is fixedly connected inside the crossbeam, two springs are respectively provided on both sides of the curved column, one end of the spring is fixedly connected to the inner wall of the crossbeam, and the other end is fixedly connected to the arc cylinder, and bolts are installed on the clamping ring.

[0014] A rapid pile extraction method using polymer cables includes the following steps: S1, Lifting Point Arrangement One end of each of the two cables is attached to the hook of the lifting equipment, and the other end is hooked to the lifting lugs 1, 2, 4 and 5 on the pipe pile, so that the lifting lugs 1, 2 and 3 are on the lifting side, and the lifting lugs 4 and 5 are on the lowering side. S2, Component Installation Install a rope-pressing and limiting component on the cable to fix the mounting sleeve on the cable and drive the pulley to fit the surface of the cable through the connecting arm. Use the damping shaft to stabilize the angle of the pulley, thereby automatically limiting the fall of excess cable during the subsequent erection process and improving the control accuracy of cable tension. S3, Lifting and Tilting The lifting equipment drives the cable to lift upwards, causing the pipe pile to start rotating around its lower lifting lug 3. By controlling the lifting speed and cable tension, the pipe pile can smoothly transition from a horizontal state to a vertical state, avoiding violent swinging or impact loads on the pipe pile. S4, Attitude Control During the rotation of the pipe pile, the cable tension and lifting speed are adjusted in real time according to the changes in the pipe pile's posture to keep the pipe pile on a stable rotation trajectory. At the same time, the high strength and low elastic modulus of the cable are utilized to ensure that the lifting force is transmitted smoothly and reliably. S5, Positioning and Fixing After the pipe pile is rotated to a vertical position, it is slowly lowered to the predetermined position. By adjusting the position of the lifting point and the length of the cable, the pipe pile is accurately lowered and kept in a vertical position, thus completing the entire pile extraction process and improving construction efficiency and safety.

[0015] The present invention has the following beneficial effects: First, using the stabilizing components, slowly lift the cable, allowing the slider to enter the inner groove and align the arc groove with the first ball bearing. Simultaneously, the slider and cable pass through the notch of the semi-circular ring. Then, twist the semi-circular ring to allow it to pass into the slider, with its notch entering the ring hole. Finally, screw the screw into the ring hole to lock the semi-circular ring, preventing the slider from dislodging from the inner groove during rotation. This ensures that the cable does not shift laterally when rotating on the lifting lug during erection, guaranteeing the vertical stability of the pipe pile during the erection process.

[0016] Second, through the rope-pressing limiting component, during the erection operation, the cables on lifting lugs two and five tilt towards the cables on lifting lugs one and four. At this time, the two pulleys push the cables on lifting lugs one and four respectively under the tilting action of the mounting sleeve. Under the tilting force, the connecting arm pushes the pulley to always keep in contact with the surface of the cable, maintaining continuous pressure on the cable and forming a squeezing constraint on the excess hanging cable, preventing it from randomly drifting away or entangled in the pipe pile or other working parts due to tilting and shaking. At the same time, it can further rotate the cable rings on lifting lugs one and four to one side, avoiding the movement path of the subsequent one-way stop and preventing subsequent limitation of the one-way stop.

[0017] Third, by using the rope-pressing limiting component, when the vertical operation is about to be completed, the two one-way blocks contact the lifting lug one and lifting lug four respectively, and pass through the one-way blocks under the action of the second ball. At this time, the two one-way blocks limit the lifting lug one and lifting lug four respectively, preventing the cable from retracting in the opposite direction and avoiding the pipe pile from falling or tilting due to the force fluctuation at the end of the erection.

[0018] Fourth, through the wind-resistant components, during the offshore hoisting process, when the wind force acts on the pipe pile, the pipe pile drives the square sleeve to swing through the clamping ring. The arc cylinder slides on the curved column and squeezes the springs on both sides. The spring deformation generates a reverse force to counteract the lateral thrust brought by the wind force, absorb the impact force of the wind on the pipe pile, reduce the swing amplitude of the pipe pile caused by the wind force, and prevent the pipe pile from deviating from the preset vertical position. Moreover, since the square sleeve is rotatably connected to the installation block, the pipe pile cannot adjust the angle, ensuring the smooth progress of the erection operation.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Example 1: Reference Figure 1 and Figure 3 A polymer cable rapid pile extraction tool includes a pipe pile 6, lifting lug 1, lifting lug 2, lifting lug 3, lifting lug 4, lifting lug 5, four stabilizing components, two rope pressing and limiting components, and two wind-resistant components. Lifting lug 1 and lifting lug 2 are fixedly installed side by side on the pipe pile 6. Lifting lug 4 and lifting lug 5 are fixedly installed side by side on the pipe pile 6. Lifting lug 3 is fixedly installed below the pipe pile 6, between lifting lug 1 and lifting lug 2. Lifting lug 3 is used to share the upward lifting force with lifting lug 1 and lifting lug 2 during the erection operation, and cooperate to lift the bottom of the pipe pile 6 and adjust its posture. Lifting lug 4 and lifting lug 5 gradually fall during the erection operation, so that the pipe pile 6 can be erected smoothly. Lifting lug 1, lifting lug 2, lifting lug 4, and lifting lug 5 are all provided with an inner groove 31. The inner groove 31 is used to accommodate the slider 23 of the stabilizing component and provide it with a sliding track. Lifting lug 1, lifting lug 2, lifting lug 4, and lifting lug 5 are all provided with two annular holes 30. The annular holes 30 are used for the semicircular ring 22 and the screw rod 21 of the stabilizing component to pass through and lock. A crossbeam 7 is provided above the pipe pile 6. The crossbeam 7 is used to connect the two Two hanging parts 10 are fixedly installed on the crossbeam 7 to distribute the lifting force to the pipe pile 6. The hanging parts 10 are used to install on the lifting equipment and transmit the lifting force of the lifting equipment to the crossbeam 7. The two hanging parts 10 are respectively equipped with hooks 9, which are used to hang the lifting cable 8 and transmit the lifting force. The two hooks 9 are respectively hung with polymer cable 8. The cable 8 on the lifting lug 1 and lifting lug 2 are connected in series through hooks 9. The cable 8 on the lifting lug 4 and lifting lug 5 are connected in series through hooks 9. The cable 8 is used to transmit the lifting force and adapt to the marine operation environment. One end of the two sets of cable 8 is hooked to the lifting lug 1 and lifting lug 2 and the lifting lug 4 and lifting lug 5 respectively. One end of the cable 8 is fixedly installed with a sling 16. The sling 16 is used to cooperate with the lifting lug 1, lifting lug 2, lifting lug 4 and lifting lug 5 to transmit the lifting force, and at the same time to drive the slider 23 of the stabilizing component to slide in the inner groove 31. The stabilizing components are used to maintain stability when the pipe pile 6 is erected; The rope-pressing and limiting component can prevent excess cable 8 from sagging; Wind-resistant components are used to reduce the impact of wind on pile driving operations.

[0023] In this embodiment, the lifting equipment causes the hook 9 to lift the cable 8 upward, so that the lifting lugs 1, 2, and 3 hooked to the cable 8 move upward synchronously. Meanwhile, the other hook 9 drives the cable 8 downward, so that the lifting lugs 4 and 5 gradually fall. With the upward pull of the lifting lugs 1, 2, and 3 and the downward movement of the lifting lugs 4 and 5, the center of gravity of the pipe pile 6 gradually adjusts with rotation, so that the pipe pile 6 gradually changes from a horizontal state to a vertical state, and finally completes the erection.

[0024] Example 2: Unlike Example 1, referring to Figure 1 , Figure 3 , Figure 5 and Figure 6 This embodiment also has the following further features: The stabilizing component includes a slider 23, several first balls 24, two semicircular rings 22, an arc groove 25, and a lead screw 21. The slider 23 is fixedly connected to the cable ring 16 and moves synchronously with the cable ring 16 and slides in the inner groove 31. The first balls 24 are movably connected in the inner groove 31 and are used to convert the sliding friction between the slider 23 and the inner groove 31 into rolling friction. The arc groove 25 is provided on the slider 23 and is used to fit with the first balls 24 and provide a sliding track for the slider 23. The two semicircular rings 22 are slidably connected to the slider 23 respectively and are used to cover the slider 23 from both sides and limit its lateral displacement.

[0025] Two semicircular rings 22 are slidably connected to the slider 23, which are used to cover the slider 23 from both sides and restrict its lateral displacement. The two semicircular rings 22 are slidably connected to the two ring holes 30, which are used to position and slide the semicircular rings 22 on the lifting lug. The screw 21 is slidably connected to the two ring holes 30, which are used to pass through the two ring holes 30 and lock the two semicircular rings 22 on the slider 23. The slider 23 is slidably connected to the inner groove 31, which is used to move along the inner groove 31 and drive the cable ring 16 to rotate. The arc groove 25 is attached to the first ball 24 to ensure that the slider 23 slides smoothly. One end of the screw 21 is provided with a torsion handle, which is used to facilitate the operator to turn the screw 21 to lock and unlock.

[0026] In this embodiment, the cable 8 is first slowly lifted, the slider 23 enters the inner groove 31 and the arc groove 25 fits with the first ball bearing 24. At the same time, the slider 23 and the cable 8 pass through the notch of the semi-circular ring 22. Then, the semi-circular ring 22 is twisted to pass into the slider 23, and its notch enters the ring hole 30. Finally, the screw rod 21 is screwed into the ring hole 30 to lock the semi-circular ring 22, preventing the slider 23 from dislodging from the inner groove 31 when rotating. This ensures that the cable 8 does not shift laterally when rotating on the lifting lug during the erection operation, thus ensuring the vertical stability of the pipe pile 6 during the erection process.

[0027] Example 3: Reference Figure 1 and Figure 3 Compared to Embodiment 1 and Embodiment 2, in this embodiment: The rope-pressing and limiting assembly includes a mounting sleeve 15, a pulley 13, two connecting arms 14, two extending arms 17, two one-way stops 18, and several second ball bearings 20. The mounting sleeve 15 is fixedly mounted on the cable 8 and is used to move synchronously with the cable 8 and drive the connecting arms 14 and extending arms 17 to move. The pulley 13 is attached to the cable 8 and is used to compress and constrain the cable 8 and limit the excess cable 8 from falling. The two extending arms 17 are fixedly connected to both sides of the mounting sleeve 15 and are used to install the one-way stops 18 and move synchronously with the mounting sleeve 15.

[0028] One end of each of the two connecting arms 14 is rotatably connected to the mounting sleeve 15, and the other end is rotatably connected to the pulley 13. These arms are used to keep the pulley 13 in contact with the surface of the cable 8 and to transmit the tilting force of the mounting sleeve 15. A damping shaft is provided at the connection point between the connecting arm 14 and the mounting sleeve 15 to keep the angle between the connecting arm 14 and the pulley 13 upwards. This ensures that the pulley 13 is always in a position that can contact and press against the cable 8, preventing the pulley 13 from flipping downwards and detaching from the cable 8 due to gravity or external forces. On the surface, a one-way stop 18 is rotatably connected to one end of the extension arm 17, which is used to contact the lifting lug and form a limit at the end of the erection operation. A torsion spring is provided at the connection between the one-way stop 18 and the extension arm 17, which is used to reset after the lifting lug is inserted. At the same time, the one-way stop 18 can only rotate towards the mounting sleeve 15 in the initial state. Several second ball bearings 20 are movably connected to one end of the one-way stop 18 to reduce the friction between the one-way stop 18 and the lifting lug and to allow the one-way stop 18 to pass smoothly through the lifting lug.

[0029] In this embodiment, during the erection operation, the cables 8 on lifting lugs 2 and 5 tilt towards the cables 8 on lifting lugs 1 and 4. At this time, the two pulleys 13, under the tilting action of the mounting sleeve 15, push the cables 8 on lifting lugs 1 and 4 respectively. Under the tilting force, the connecting arm 14 pushes the pulleys 13 to always keep in contact with the surface of the cables 8, maintaining continuous pressure on the cables 8, forming a squeezing constraint on the excess hanging cables 8, preventing them from randomly drifting away or entangled in the pipe pile 6 or other working parts due to tilting and swaying. At the same time, it can... The cable rings 16 at lifting lug 1 and lifting lug 4 will be rotated to one side to avoid the movement path of the subsequent one-way stop 18 and prevent the one-way stop 18 from being restricted. When the vertical operation is about to be completed, the two one-way stops 18 will contact lifting lug 1 and lifting lug 4 respectively, and pass through the one-way stops 18 under the action of the second ball bearing 20. At this time, the two one-way stops 18 will restrict lifting lug 1 and lifting lug 4 respectively, preventing the cable 8 from retracting in the opposite direction and preventing the pipe pile 6 from falling or tilting due to the force fluctuation at the end of the erection.

[0030] Example 4: Reference Figure 1 , Figure 2 and Figure 6 Compared to Embodiment 1, Embodiment 2, and Embodiment 3, in this embodiment: The wind-resistant component includes two clamping rings 11, a mounting block 29, a square sleeve 12, an arc cylinder 26, a bent column 28, and two springs 27. The clamping rings 11 are mounted on the pipe pile 6 and are used to clamp and fix it to the outer wall of the pipe pile 6 and transmit the swing generated by the wind to the mounting block 29. The two clamping rings 11 are rotatably connected to the mounting block 29 respectively, so that the pipe pile 6 drives the mounting block 29 to rotate synchronously and adapt to the angle change when swinging. One end of the square sleeve 12 is rotatably connected to the mounting block 29 and is used to rotate with the mounting block 29 and drive the arc cylinder 26 to slide along the bent column 28.

[0031] The arc cylinder 26 is fixedly connected to one end of the square sleeve 12 and is used to slide on the curved column 28 and compress the springs 27 on both sides. The curved column 28 is fixedly connected inside the crossbeam 7 and is used to provide a sliding track for the arc cylinder 26 and limit its movement direction. Two springs 27 are respectively located on both sides of the curved column 28 and are used to generate a reverse force through elastic deformation to counteract the lateral thrust brought by the wind. One end of the spring 27 is fixedly connected to the inner wall of the crossbeam 7 and the other end is fixedly connected to the arc cylinder 26. It is used to convert the impact force generated by the wind into the elastic potential energy of the spring 27 and achieve buffering and reset. Bolts 19 are installed on the clamping ring 11 to lock and fix the two clamping rings 11 to the pipe pile 6 and ensure a stable connection.

[0032] In this embodiment, during the offshore hoisting process, when the wind force acts on the pipe pile 6, the pipe pile 6 drives the square sleeve 12 to swing through the clamping ring 11. The arc cylinder 26 slides on the curved column 28 and squeezes the springs 27 on both sides. The deformation of the springs 27 generates a reverse force to counteract the lateral thrust brought by the wind force, absorb the impact force of the wind on the pipe pile 6, reduce the swing amplitude of the pipe pile 6 caused by the wind force, and prevent the pipe pile 6 from deviating from the preset vertical position. Furthermore, since the square sleeve 12 is rotatably connected to the mounting block 29, the pipe pile 6 cannot adjust its angle, ensuring that the erection operation proceeds smoothly.

[0033] A rapid pile extraction method using polymer cables includes the following steps: S1, Lifting Point Arrangement One end of each of the two cables 8 is hung on the hook 9 of the lifting equipment, and the other end is hooked to the lifting lugs 1, 2, 4, and 5 on the pipe pile 6 respectively, so that the lifting lugs 1, 2, and 3 are located on the lifting side, and the lifting lugs 4 and 5 are located on the falling side. S2, Component Installation Install a rope pressing and limiting component on the cable 8 so that the mounting sleeve 15 is fixed on the cable 8 and the connecting arm 14 drives the pulley 13 to fit against the surface of the cable 8. Use the damping shaft to stabilize the angle of the pulley 13, thereby automatically limiting the fall of excess cable 8 during the subsequent erection process and improving the tension control accuracy of the cable 8. S3, Lifting and Tilting The lifting equipment drives the cable 8 to lift upwards, causing the pipe pile 6 to start rotating around its lower lifting lug 3. By controlling the lifting speed and the tension of the cable 8, the pipe pile 6 can smoothly transition from a horizontal state to a vertical state, avoiding violent swinging or impact loads on the pipe pile 6. S4, Attitude Control During the rotation of the pipe pile 6, the tension of the cable 8 and the lifting speed are adjusted in real time according to the changes in the posture of the pipe pile 6, so that the pipe pile 6 maintains a stable rotation trajectory. At the same time, the high strength and low elastic modulus of the cable 8 are utilized to ensure that the lifting force is transmitted smoothly and reliably. S5, Positioning and Fixing After the pipe pile 6 is rotated to a vertical position, it is slowly lowered to the predetermined position. By adjusting the position of the lifting point and the length of the cable 8, the pipe pile 6 is accurately lowered and kept in a vertical position, thus completing the entire pile extraction process and improving construction efficiency and safety. The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

8. A method for rapid pile extraction using polymer cables, employing the rapid pile extraction tooling described in any one of claims 1-7, characterized in that... Includes the following steps: S1, Lifting Point Arrangement Hang one end of each of the two cables (8) on the hook (9) of the lifting equipment, and hook the other end to the lifting lugs 1 (1), 2 (2), 4 (4), and 5 (5) on the pipe pile (6), so that the lifting lugs 1 (1), 2 (2), and 3 (3) are on the lifting side, and the lifting lugs 4 (4) and 5 (5) are on the falling side; S2, Component Installation Install a rope-pressing and limiting component on the cable (8) so that the mounting sleeve (15) is fixed on the cable (8) and the pulley (13) is driven by the connecting arm (14) to fit against the surface of the cable (8). The angle of the pulley (13) is stabilized by the damping shaft, thereby automatically limiting the fall of excess cable (8) during the subsequent erection process and improving the tension control accuracy of the cable (8). S3, Lifting and Tilting The lifting equipment drives the cable (8) to lift upward, so that the pipe pile (6) starts to rotate around the lower lifting lug three (3). By controlling the lifting speed and the tension of the cable (8), the pipe pile (6) can smoothly transition from a horizontal state to a vertical state, avoiding violent swinging or impact load on the pipe pile (6). S4, Attitude Control During the rotation of the pipe pile (6), the tension of the cable (8) and the lifting speed are adjusted in real time according to the changes in the posture of the pipe pile (6) so that the pipe pile (6) maintains a stable rotation trajectory. At the same time, the high strength and low elastic modulus of the cable (8) are utilized to ensure that the lifting force is transmitted smoothly and reliably. S5, Positioning and Fixing After the pipe pile (6) is rotated to a vertical position, the pipe pile (6) is slowly lowered to the predetermined position. By adjusting the position of the lifting point and the length of the cable (8), the pipe pile (6) is accurately lowered and kept in a vertical position, thus completing the entire pile extraction process and improving construction efficiency and safety.
