Description

Technical Field

[0001] The invention relates to the technical field of wind power pipe pile lifting, and in particular to a lifting and pile-turning hoisting device for offshore wind power pipe piles. Background Art

[0002] Wind power generation is a very environmentally friendly green energy technology. While the construction of onshore wind farms is developing rapidly, there are many limitations, such as large land area and noise pollution. Therefore, offshore wind power generation technology is a power generation equipment that can properly solve the above problems. In the process of building offshore wind power foundations, its steel pipe piles need to be transported to the construction site by transport ships for lifting and installation, which requires the use of lifting and turning pile hoists to perform the lifting task.

[0003] The Chinese patent application with the publication number CN114249228A proposes an offshore wind power steel pipe pile lifting and turning device and its construction method, which includes: a shell, the shell is cylindrical, and a first baffle is provided at the rear end of the shell; a plurality of telescopic components, the plurality of telescopic components are all arranged in the shell, the plurality of telescopic components are evenly distributed along the circumference of the shell, and the plurality of telescopic components can slide along the radial direction of the shell; and a clamping component, the clamping component is arranged in the shell, the clamping component can slide along the axial direction of the shell, the clamping component is used to drive the telescopic component to slide toward the steel pipe pile, and press the telescopic component against the inner wall of the steel pipe pile, and the rear end of the clamping component is rotatably provided with a lifting lug. It can automatically connect with the steel pipe pile during lifting, and separate from the steel pipe pile after the pile is sunk, without the need for operators to dive underwater to perform auxiliary operations such as unhooking, thereby improving construction efficiency and reducing the operating risks of construction personnel.

[0004] The above device reduces the operation risk of construction workers by connecting the clamping component to the pipe pile automatically during lifting. However, the entire lifting process only relies on the gravity of the lifting device after lifting the lifting ring to simultaneously achieve the purpose of pressing against the inner wall of the pipe pile. The means are relatively simple. Especially in the process of turning over the pipe pile, since the pulling force on the lifting device is not completely perpendicular to the ground, the pressing force cannot reach the maximum, and the friction may be insufficient, causing the lifting device to directly detach from the inside of the pipe pile, resulting in the problem that stability and safety cannot be guaranteed.

The electric hydraulic rod 595 controls the first control block 4 to push and control the first control block 4 to push the first trapezoidal plate 593. At this time, the first trapezoidal plate 593 moves horizontally until the first bonding plate 52 is tightly attached to the inner wall of the pipe pile. After the control plug plate 582 passes through the T-shaped plate 594, the stability of the first control block 4 can be improved to reduce the pressure of the electric hydraulic rod 595 to maintain the bonding plate tightly attached to the inner wall of the pipe pile, so that the pipe pile can maintain a stable posture during the turning and lifting process, and there will be no unhooking phenomenon, thereby ensuring stability and safety.One end of the positioning plate 58 is fixedly connected to the bottom of the annular plate 51, and a rectangular plate 583 is fixedly connected to the lifting plate 591. A first spring 584 is fixedly connected to the top of the rectangular plate 583. The top of the first spring 584 is fixedly connected to the inner top of the positioning plate 58. A telescopic plate 562 is fixedly connected between the first bonding plate 52 and the outer wall of the shell 1. The first spring 584 exerts an elastic force on the rectangular plate 583. The telescopic plate 562 provides a limit for the first bonding plate 52 to keep it moving horizontally stably. A first anti-slip strip 585 is integrally formed on the first bonding plate 52. The first anti-slip strips 585 are arranged at equal intervals on the first bonding plate 52. After the first anti-slip strips 585 are bonded to the inner wall of the pipe pile, they can properly play an anti-slip role.

[0044] Two limit plates 586 are fixedly connected to the bottom wall of the inner cavity of the shell 1. The two limit plates 586 both penetrate the bottom wall of the T-shaped plate 594. The limit plates 586 provide limitation for the T-shaped plate 594 so that it can be stably lifted and lowered vertically. The U-shaped plate 581 is internally rotatably connected with a first threaded rod 587. The first threaded rod 587 penetrates a side wall of the plug plate 582 and is connected to the plug plate 582 by threads. A motor 588 is fixedly connected to one side wall of the U-shaped plate 581.

[0045] A second threaded rod 589 is rotatably connected inside the frame 596, and the second threaded rod 589 extends out of the frame 596. A push plate 571 is arranged inside the frame 596, and the push plate 571 passes through the bottom wall of the shell 1 and extends to the inside of the frame plate 597. The second threaded rod 589 passes through the bottom wall of the push plate 571 and is connected to the push plate 571 by threads. The tops of both ends of the push plate 571 are respectively fixedly connected to the bottoms of the first auxiliary plate 598 and the second auxiliary plate 599. A circular plate 572 is fixedly connected to the bottom of the second threaded rod 589. An inner ring plate 573 and an outer ring plate 574 are arranged at the bottom of the frame 596. The outer ring plate 574 is arranged on the outside of the inner ring plate 573. A connecting plate 575 is fixedly connected between the outer ring plate 574 and the bottom wall of the circular frame. A vertical groove is opened on one side wall of the frame 596, and a scale bar 576 is fixedly connected on one side wall of the frame 596. After the second threaded rod 589 rotates, it can drive the push plate 571 to move;

[0046] A pointer plate 577 is fixedly connected to one side wall of the push plate 571. The pointer plate 577 passes through the vertical groove and matches the vertical groove. A positioning bracket 578 is fixedly connected between the inner ring plate 573 and the outer ring plate 574. A bolt rod 579 is fixedly connected to the bottom of the circular plate 572. A positioning nut 561 is arranged on the outside of the bolt rod 579. The bolt rod 579 passes through the positioning nut 561 and is threadedly connected to the positioning nut 561. One side of the positioning nut 561 is respectively fitted with one side of the inner ring plate 573 and the outer ring plate 574. After the positioning nut 561 is tightened on the outside of the bolt rod 579, the circular plate 572 cannot rotate.

[0047] A second control block 6 is arranged inside the shell 1, and a passive positioning mechanism 7 is arranged outside the second control block 6. The passive positioning mechanism 7 includes a round rod 71, which is fixedly connected to the top of the second control block 6, and the round rod 71 passes through the top plate 2. A mounting seat 72 is fixedly connected to the top of the round rod 71, and a hanging ring 73 is arranged on the top of the mounting seat 72. The hanging ring 73 extends into the inside of the mounting seat 72 and is connected to the mounting seat 72 through a rotating shaft. A second bonding plate 74 is arranged outside the shell 1, and an intermediate plate 75 is fixedly connected to one side of the second bonding plate 74. The intermediate plate 75 extends into the inside of the shell 1, and a second trapezoidal plate 76 is fixedly connected to one side of the intermediate plate 75.

[0048] The second trapezoidal plate 76 is arranged on the outside of the second control block 6 and contacts the second control block 6. A guide rod 77 is fixedly connected to the middle plate 75. The guide rod 77 extends out of the outside of the shell 1. A friction head 78 is integrally formed at one end of the guide rod 77. A second spring 79 is fixedly connected between the second bonding plate 74 and the outer wall of the shell 1. The guide rod 77 can improve the stability of the middle plate 75 when it moves. A second anti-slip strip 791 is integrally formed on the second bonding plate 74. The second anti-slip strips 791 are arranged at equal intervals on the second bonding plate 74. After the second anti-slip strip 791 is bonded to the inner wall of the pile, it can also play an anti-slip role.

[0049] A flat hook 8 is fixedly connected to the top of the top plate 2, and a lifting hole is opened on the flat hook 8. After the crane is connected with the flat hook 8 and hoisted at this time, the device can be adjusted to a horizontal posture.

[0050] In actual operation, when the device is used, the battery pack body 3 in the device provides power supply for the electric hydraulic rod 595 and the motor 588. When in use, the lifting ring 73 on the device is connected to the main lifting of the crane, and the flat hook 8 can be connected to the auxiliary lifting of the crane. After the connection is completed, the flat hook 8 is lifted by the auxiliary lifting alone, which can cause the device to flip to a posture horizontal with the pipe pile. Then, the device is inserted into the inner wall of the pipe pile to perform the pile turning and lifting operation. When the device is inserted, the flat hook 8 is outside the pipe pile, wherein the first spring 584 and the second spring 79 respectively exert elastic forces on the rectangular plate 583 and the second bonding plate 74. After the rectangular plate 583 is subjected to force, it drives the lifting plate 591 to move downward. It can be seen from the above connection relationship that at this time, the first bonding plate 52 moves toward the shell 1, and the second bonding plate 74 also moves toward the shell 1 after being subjected to force, so that the first bonding plate 52 and the second bonding plate 74 can both remain in a tightened state under the action of no external force, which is more conducive to the smooth placement of the device into the pipe pile.

[0051] After the device is placed inside the pipe pile until the end of the pipe pile is attached to the top plate 2, the electric hydraulic rod 595 first works to push the T-shaped plate 594, and the T-shaped plate 594 drives the first control block 4 to move. After the first control block 4 moves, it fits with the inclined surface of the first trapezoidal plate 593. As the movement continues, the first trapezoidal plate 593 can be pushed to cause the first trapezoidal plate 593 to move vertically. The first trapezoidal plate 593 drives the lifting plate 591 to move, and the lifting plate 591 drives the rack 592 to move. The rack 592 drives the gear 57 to rotate, and the gear 57 drives the installation rod 55 to rotate. The installation rod 55 drives the push-pull rod 56 to flip, and the push-pull rod 56 pushes the movable block 53, and the movable block 53 drives the first bonding plate 52 moves until the first laminating plate 52 is attached to the inner wall of the pile, and there is friction between the first laminating plate 52 and the inner wall of the pile, and then the motor 588 drives the first threaded rod 587 to rotate after working, and the first threaded rod 587 drives the plug plate 582 to move, and the plug plate 582 moves to pass through the T-shaped plate 594 and the second auxiliary plate 599, and the plug plate 582 provides support for the T-shaped plate 594. It can be seen from the above steps that the stability of the first control block 4 after pushing the first control block 4 can be further improved, so as to reduce the pressure of the electric hydraulic rod 595 to keep the laminating plate close to the inner wall of the pile, so that the pile can maintain a stable posture during the turning and lifting process, and there will be no unhooking phenomenon, thereby ensuring stability and safety;

[0052] When lifting and turning over piles of different diameters, the second threaded rod 589 can be rotated according to the different inner diameters of the piles, and the second threaded rod 589 drives the push plate 571 to move, and the push plate 571 pushes the first auxiliary plate 598 and the second auxiliary plate 599 up and down synchronously, and the first auxiliary plate 598 drives the height of the plug plate 582 to adjust, and the push plate 571 also drives the pointer plate 577 to move when it moves, and at this time, the indicating end of the pointer plate 577 is made to correspond to the scale bar 576, so as to accurately adjust the height of the plug plate 582, so that when the first fitting plate 52 fits with different inner diameters of piles, the first control block 4 stays at different heights, and at this time, the plug plate 582 can still accurately penetrate the T-shaped plate 594, thereby improving the applicability of the device;

[0053] When the first laminating plate 52 is in contact with the inner wall of the pile, the crane can lift the lifting ring 73 through the main lifting, and the lifting ring 73 drives the mounting seat 72 to move, and the mounting seat 72 drives the round rod 71 to move, and the round rod 71 drives the second control block 6 to move. After the second control block 6 moves, it pushes the inclined surface on the second trapezoidal plate 76. At this time, the second trapezoidal plate 76 moves horizontally, and the second trapezoidal plate 76 drives the middle plate 75 to move. After the middle plate 75 drives the second laminating plate 74 to move to fit the inner wall of the pile, there is friction between the two. In this process, the middle plate 75 also drives the guide rod 77 to move, and the guide rod 77 can provide guidance for the middle plate 75 to improve the stability of the middle plate 75 when it moves horizontally. Qualitatively, while the second bonding plate 74 is in contact with the inner wall of the pile, the friction head 78 at one end of the guide rod 77 is also in contact with the inner wall of the pile, which can increase the friction between the inner wall of the pile and the guide rod. Based on the force of the first bonding plate 52, the second bonding plate 74 and the friction head 78 in contact with the inner wall of the pile, the safety of the pile during the pile turning and lifting process can be guaranteed, and the structure that relies solely on the force of pulling for positioning can be avoided. During the pile turning process, the pulling force on the lifting device is not completely perpendicular to the ground, so the tightening force cannot reach the maximum, and the friction may be insufficient, causing the lifting device to directly detach from the inside of the pile, resulting in the problem that stability and safety cannot be guaranteed.

[0054] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
