Description

Technical Field

[0001] The present invention relates to the field of hoisting tools, and in particular to a hoisting and turning tool for an offshore wind power pile and a turning method thereof. Background Art

[0002] An offshore wind power pile is one of the basic structures of an offshore wind turbine. The overall size, mass, and weight of the wind power pile are large. The common construction method is as follows: The wind power pile is transported to a designated area by a transport ship, and then a lifting ship is used to hoist and turn the pile to an upright position. In actual use, due to the placement state limitation of the wind power pile on the transport ship, it is easy to have a cross misalignment between the lifting lugs on the wind power pile and the two lifting hooks on the lifting arm of the lifting ship, resulting in the inability to perform the turning and hoisting operation on the wind power pile.

[0003] In the prior art, usually a single-beam lifting beam is installed on the lifting arm of the lifting ship. The related technology can refer to the Chinese patent with the publication number CN112897339A, which discloses a method for turning a large-diameter single pile of a full-rotation lifting ship, including the following steps: S1: Ship positioning, the lifting ship and the transport ship travel to the wind farm position and drop anchor for positioning to keep the position relatively stable; S2: Select appropriate slings, main lifting ropes, and auxiliary lifting ropes, and weld a cushion beam and a stopper on the transport ship in advance to facilitate the fixed placement of the single pile; S3: The main lifting rope hangs the sling parallel on the main hook, an auxiliary rope is hung on the auxiliary hook, one end of the auxiliary lifting rope is hung on the main hook, the main lifting rope is connected to the lifting lugs on both sides of the single pile, and the other end of the auxiliary lifting rope is provided with a trailing hook and fixed to the other end of the single pile; S4: The main hook lifts the single pile. After the single pile leaves the transport ship, the transport ship sails away from the lifting ship. After the trailing hook of the single pile is unhooked, the single pile is continuously lifted to the vertical position to complete the pile turning.

[0004] Regarding the above related technology, during the hoisting and turning of the offshore wind power pile, it is necessary to first select suitable slings and hang and install the slings, and then the wind power pile can be hoisted and turned through the cooperation of the slings and the main hook. Due to the large weight of the wind power pile, the slings need to have a sufficiently high load-bearing capacity, resulting in a relatively large self-weight of the slings. Therefore, it is inconvenient to install the slings, affecting the overall convenience of hoisting and turning the wind power pile. Summary of the Invention

[0005] In order to improve the convenience during the hoisting and turning of the offshore wind power pile, the present application provides a hoisting and turning tool for an offshore wind power pile and a turning method thereof.

[0006] The present application provides a hoisting and turning tool for an offshore wind power pile, adopting the following technical solution: An offshore wind power pile hoisting and turning tooling, comprising an upper lifting arm and a lower lifting arm. The lower lifting arm is located at the lower end of the upper lifting arm, and the lower lifting arm is vertically arranged with the upper lifting arm in the working state. At both ends of the upper end of the upper lifting arm along the length direction, there are first hook connecting parts, and both of the two first hook connecting parts are used for connecting the lifting lugs of the wind power pile. At both ends of the upper end of the lower lifting arm along the length direction, there are second hook connecting parts. An auxiliary hook is hinged at the lower end of the lower lifting arm, and the auxiliary hook is located at the midpoint of the connection line between the two second hook connecting parts. And a hanging block for hanging an auxiliary lifting rope is fixedly arranged on the auxiliary hook. And a hook releasing mechanism for separating the auxiliary lifting rope from the hanging block is arranged on the auxiliary hook. A connecting mechanism is arranged between the upper lifting arm and the lower lifting arm, and the upper lifting arm is detachably connected with the lower lifting arm through the connecting mechanism.

[0007] By adopting the above technical solution, when hoisting the wind power pile through a hoisting mechanism, first connect the hoisting mechanism to the two second hook connecting parts above the lower lifting arm through a lifting rope. When the wind power pile lies flat, the lower lifting arm is parallel to the wind power pile. Connect the two first hook connecting parts of the upper lifting arm to the lifting lugs on both sides of the wind power pile through another group of lifting ropes. Finally, hang the auxiliary lifting rope on the hanging block of the auxiliary hook. One end of the auxiliary lifting rope is connected to a tailing hook, and the tailing hook is hooked to the end of the wind power pile. The other end of the auxiliary lifting rope is tightened and fixed. During hoisting, the upper lifting arm and the lower lifting arm cooperate to drive the wind power pile to lift. When the wind power pile is horizontally moved to a preset position, gradually relax the auxiliary lifting rope, so that the wind power pile gradually turns over. After the tailing hook is separated from the wind power pile, drive the auxiliary lifting rope to leave the auxiliary hook through the hook releasing mechanism, and continuously lift the upper lifting arm until the wind power pile is erected, completing the turning over of the wind power pile. When turning over the wind power pile, there is no need to separately select slings, and it is more convenient to hoist and turn over the wind power pile. And the upper lifting arm and the lower lifting arm are detachably connected through the connecting mechanism, so that the upper lifting arm and the lower lifting arm can be disassembled and used or combined and used, with strong applicability.

[0008] Optionally, the connecting mechanism includes a plurality of first limiting plates and a plurality of second limiting plates. The upper end face of the lower lifting arm fits with the lower end face of the upper lifting arm. The plurality of first limiting plates are divided into two groups, and the two groups of first limiting plates are respectively fixedly connected to both ends of the lower end of the upper lifting arm along the length direction. The lower lifting arm is located between the two groups of first limiting plates and abuts against both of the first limiting plates. The plurality of second limiting plates are also divided into two groups, and the two groups of second limiting plates are fixedly connected to both ends of the upper end of the lower lifting arm along the length direction. The upper lifting arm is located between the two groups of second limiting plates and abuts against the second limiting plates.

[0009] By adopting the above technical solution, when hoisting the lower lifting arm, the lower lifting arm supports the upper lifting arm, so that the upper lifting arm is lifted synchronously. The first limiting plates are used to limit the relative movement between the lower lifting arm and the upper lifting arm along the width direction of the lower lifting arm itself. The second limiting plates are used to limit the relative movement between the upper lifting arm and the lower lifting arm along the width direction of the upper lifting arm itself, so that the upper lifting arm and the lower lifting arm remain perpendicular, and at the same time, it is convenient to disassemble and combine the upper lifting arm and the lower lifting arm, improving the use convenience.

[0010] Optionally, the decoupling mechanism includes a pulling rope, a jacking plate, a first elastic member, and a flipping plate. The direction of the auxiliary hook of the jacking plate is slidably connected to the auxiliary hook. The pulling rope is connected to the jacking plate and is used to drive the jacking plate to lift vertically. A connecting plate is vertically fixed to the lower end of the jacking plate. The connecting plate is arranged along the length direction of the line between the two hanging blocks. The flipping plate is arranged along the length direction of the connecting plate, and one end of the flipping plate away from the connecting portion is vertically hinged to the connecting plate. The first elastic member is located between the flipping plate and the connecting plate and is used to drive the flipping plate to rotate away from the jacking plate. The auxiliary hook is provided with a positioning member for limiting the flipping plate. When the flipping plate is located at the lower end of the auxiliary hook, the positioning member limits the rotation tendency of the flipping plate.

[0011] By adopting the above technical solution, in the initial state, the jacking plate is located below the hanging block, thereby avoiding the connecting plate and the flipping plate from affecting the connection stability between the auxiliary lifting rope and the hanging block. At this time, the positioning member limits the flipping plate, and the first elastic member is in a deformed state and has a tendency to drive the flipping plate to flip. When it is necessary to disconnect the auxiliary lifting rope from the hanging block, the operator drives the jacking plate to lift through the pulling rope. The jacking plate drives the flipping plate to move synchronously through the connecting plate. When the flipping plate rises, it drives the auxiliary lifting rope to gradually separate from the hanging block. When the flipping plate leaves the limiting range of the positioning member, the positioning member releases the limit on the flipping plate, prompting the first elastic member to drive the flipping plate to flip towards the side close to the jacking plate, making the flipping plate inclined, and thus facilitating the detachment of the auxiliary lifting rope from the auxiliary hook along the inclined flipping plate.

[0012] Optionally, the positioning member includes a rotating shaft and a hinged plate. The hinged plate is located at one end of the flipping plate close to the jacking plate and rotates vertically with the flipping plate. The rotating shaft passes through the end of the hinged plate away from the flipping plate and is rotatably connected to the flipping plate. The auxiliary hook is vertically provided with a straight groove. When the rotating shaft is located in the straight groove, it fits with the inner wall of the straight groove, and the flipping plate and the hinged plate are located in the same straight line. An arc groove communicating with the straight groove is provided at the upper end of the auxiliary hook. When the rotating shaft enters the arc groove along the straight groove, the first elastic member drives the flipping plate to flip.

[0013] By adopting the above technical solution, in the initial state, the rotating shaft is located in the straight groove. At this time, the auxiliary hook limits the rotating shaft through the straight groove, and thus limits the rotation tendency of the flipping plate through the hinged plate. When the jacking plate is lifted and drives the auxiliary lifting rope to separate from the hanging block through the flipping plate, the rotating shaft enters the arc groove from the straight groove and moves along the arc groove, enabling the hinged plate and the first elastic member to cooperate and drive the flipping plate to rotate, thereby improving the flipping convenience of the flipping plate.

[0014] Optionally, a baffle is hinged vertically at the upper end of the jacking plate. When a hanging block is hung with a lifting rope, one end of the baffle away from the jacking plate is located above the lifting rope. A contact block is fixedly connected to one end of the baffle close to the jacking plate. A limiting block corresponding to the contact block is fixedly connected to the jacking plate. The limiting block is located below the contact block. When the baffle rotates, it drives the contact block to approach or move away from the limiting block. An elastic member II is provided between the baffle and the jacking plate. In the natural state of the elastic member II, it drives the contact block to contact the limiting block.

[0015] By adopting the above technical solution, in the initial state, when the jacking plate is in a position close to the lower end of the auxiliary hook, the baffle is in a position close to the hanging block. When placing the auxiliary lifting rope on the hanging block, rotate the baffle to separate the contact block from the limiting block. After the auxiliary lifting rope enters between the baffle and the hanging block, the baffle resets under the action of the elastic member II, so that the contact block contacts the limiting block. The baffle and the hanging block cooperate to limit the auxiliary lifting rope, which is beneficial to improving the connection stability between the auxiliary lifting rope and the hanging block. When it is necessary to disconnect the auxiliary lifting rope from the hanging block, the baffle is synchronously lifted while the jacking plate is lifted, thereby avoiding the auxiliary lifting rope.

[0016] Optionally, a guide rail is fixedly connected to the lower boom vertically. The guide rail is slidably connected with a driving block along the length direction. The driving block is fixedly connected with a connecting rope. A lifting rope connecting piece is provided at one end of the connecting rope away from the driving block. A turning wheel is rotatably connected to the upper end of the guide rail. The connecting rope is wound around the turning wheel and connected to the lifting rope through the lifting rope connecting piece. The guide rail is also slidably connected with a driven block along the length direction. The driven block is located at one end of the driving block close to the auxiliary hook. An elastic member III is fixedly connected between the driving block and the driven block. One end of the pulling rope away from the jacking plate is fixedly connected to the driven block. The guide rail is provided with a limiting member for restricting the movement of the driven block.

[0017] By adopting the above technical solution, the connecting rope is connected to any lifting rope other than the auxiliary lifting rope through the lifting rope connecting piece. In the initial state, the driven block is restricted at one end of the guide rail close to the auxiliary hook by the limiting member. When hoisting the wind power pile, the lifting rope connected to the connecting rope is straightened and tightened. At this time, under the action of the turning wheel, the connecting rope drives the driving member away from the driven block and stretches the elastic member III. When it is necessary to unhook the auxiliary lifting rope, the limiting of the driven block by the limiting member is released, so that the driven block moves along the guide rail away from the auxiliary hook under the action of the elastic member III. When the driven block moves, it drives the jacking plate to move through the pulling rope, completing the unhooking of the auxiliary lifting rope.

[0018] Optionally, the limiting member includes a translation block, a pushing block, an elastic member IV, and a disassembly rope. A fixing block is fixedly connected to the side of the driven block facing away from the lower boom. The translation block is slidably connected to the guide rail in the transverse direction. The elastic member IV is located between the guide rail and the translation block and is used to drive the translation block closer to the driven block. When the surface of the translation member facing the auxiliary hook abuts against the fixing block, the movement of the driven block away from the auxiliary hook is restricted. The pushing block is slidably connected to the guide rail along the length direction of the guide rail. The disassembly rope is fixedly connected to the pushing block and is used to drive the pushing block to move away from the auxiliary hook. A guiding surface facing the translation block is provided at the upper end of the pushing block, and when the guiding surface contacts the translation block, it drives the translation block away from the fixing block.

[0019] By adopting the above technical solution, in the initial state, the translation block contacts the fixing block under the action of the elastic member IV, and then the driven block is limited through the fixing block. When it is necessary to release the limit on the driven block, the operator pulls the disassembly rope to drive the pushing block to move along the guide rail. After the guiding surface of the pushing block contacts the translation block, it pushes the translation block away from the fixing block. After the translation block is separated from the fixing block, the driven block moves closer to the driving block under the action of the elastic member IV, and then drives the jacking plate to move through the pulling rope.

[0020] Optionally, a top plate is fixedly connected to the lower end of the pushing block, and the top plate is directly opposite to the end face of the fixing block close to the auxiliary hook.

[0021] By adopting the above technical solution, when the pushing block moves, it drives the top plate to move. If the lifting rope connector is separated from the corresponding lifting rope, resulting in the elastic member IV not being deformed, the pushing block is directly lifted by pulling the disassembly rope. After the pushing block moves the top plate to contact the fixing block, it pushes the fixing block and the driven block to move away from the auxiliary hook, thereby realizing the unhooking of the auxiliary lifting rope, which is beneficial to improving the unhooking stability of the auxiliary lifting rope.

[0022] In a second aspect, the present application provides a turning-over method, which is applied to a turning-over tooling for hoisting an offshore wind power pile and adopts the following technical solutions: Positioning: The transportation ship and the crane ship drop anchor and position at the designated position and maintain relative stability; Selecting the lifting rope: Connect the two hook connecting parts II above the lower boom with the lifting mechanism of the crane ship through the lifting rope, so that the lifting mechanism hoists the lower boom and the upper boom; Selecting the main lifting rope: Connect the two hook connecting parts I on the upper boom with the lifting lugs on both sides of the wind power pile through the main lifting rope respectively; Selecting the auxiliary lifting rope: Hang the auxiliary lifting rope under the auxiliary hook, and connect the lower end of the auxiliary lifting rope to the tailing hook, and connect it to the end of the wind power pile through the tailing hook; Lifting: The lifting mechanism hoists the lower boom. When the lower boom moves, it lifts the wind power pile through the upper boom. After the wind power pile leaves the transportation ship, the transportation ship sails away from the crane ship; Disconnect the hook, continuously lift the wind power pile until the tailing hook disconnects from the wind power pile, then use the decoupling mechanism to disengage the auxiliary lifting rope from the auxiliary hook, and then continuously lift the wind power pile to the vertical until the pile turning is completed.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. When lifting the wind power pile by the lifting mechanism, first connect the lifting mechanism to the two hook connection parts II above the lower boom through the lifting rope. When the wind power pile lies flat, the lower boom is parallel to the wind power pile. Connect the two hook connection parts I of the upper boom to the lifting lugs on both sides of the wind power pile through another set of lifting ropes. Finally, hang the auxiliary lifting rope on the hanging block of the auxiliary hook. One end of the auxiliary lifting rope is connected to the tailing hook and is hooked to the end of the wind power pile through the tailing hook, and the other end of the auxiliary lifting rope is tightened and fixed. During hoisting, the upper boom and the lower boom cooperate to drive the wind power pile to lift. When the wind power pile moves horizontally to the preset position, gradually loosen the auxiliary lifting rope to make the wind power pile gradually turn over. After the tailing hook separates from the wind power pile, drive the auxiliary lifting rope to the auxiliary hook through the decoupling mechanism, and continuously lift the upper boom until the wind power pile is erected to complete the turning of the wind power pile. When turning over the wind power pile, there is no need to separately select slings, which is more convenient when hoisting and turning over the wind power pile. Moreover, the upper boom and the lower boom are detachably connected through the connecting mechanism, so that the upper boom and the lower boom can be disassembled for use or combined for use, with strong applicability; 2. In the initial state, the jacking plate is located below the hanging block, thus avoiding the connecting plate and the turning plate from affecting the connection stability between the auxiliary lifting rope and the hanging block. At this time, the positioning member limits the turning plate, and the first elastic member is in a deformed state and has a tendency to drive the turning plate to turn over. When it is necessary to disengage the auxiliary lifting rope from the hanging block, the operator drives the jacking plate to rise through the pull rope. The jacking plate drives the turning plate to move synchronously through the connecting plate. When the turning plate rises, it drives the auxiliary lifting rope to gradually separate from the hanging block. When the turning plate leaves the limiting range of the positioning member, the positioning member releases the limit on the turning plate, prompting the first elastic member to drive the turning plate to turn over towards the side close to the jacking plate, making the turning plate inclined, thus facilitating the auxiliary lifting rope to disengage from the auxiliary hook along the inclined turning plate.

Detailed implementation manners

[0030] The following further describes the present application in detail with reference to all the drawings.

[0031] An embodiment of the present application discloses an offshore wind power pile hoisting and turning tooling and a turning method.

[0032] Embodiment: Referring to Figure 1 , an offshore wind power pile hoisting and turning tooling includes an upper lifting arm 1 and a lower lifting arm 2. First hook connection parts 11 are arranged at both ends of the lower lifting arm 2 along the length direction. When it is necessary to hoist and turn the wind power pile, first, two hoisting ropes are respectively connected to the two first hook connection parts 11 through a hoisting mechanism, so that the hoisting mechanism suspends the lower lifting arm 2. The upper lifting arm 1 is located at the upper end of the lower lifting arm 2 and is perpendicularly arranged with the lower lifting arm 2, and the lower end surface of the upper lifting arm 1 abuts against the upper end surface of the lower lifting arm 2. When the lower lifting arm 2 is lifted, the upper lifting arm 1 is driven to lift.

[0033] Referring to Figure 1, a connecting mechanism is provided between the upper lifting arm 1 and the lower lifting arm 2. The connecting mechanism includes two groups of first limiting plates 41 and two groups of second limiting plates 42. The two groups of first limiting plates 41 are respectively located at both ends of the upper lifting arm 1 along the length direction. The lower lifting arm 2 is located between the two groups of first limiting plates 41 and abuts against both groups of first limiting plates 41. The upper lifting arm 1 limits the lower lifting arm 2 through the first limiting plates 41, thereby restricting the displacement between the lower lifting arm 2 and the upper lifting arm 1 along the width direction of the lower lifting arm 2 itself. The two groups of second limiting plates 42 are both located at the upper end of the lower lifting arm 2 and are fixedly connected to both ends of the lower lifting arm 2 along the length direction. The upper lifting arm 1 is located between the two groups of second limiting plates 42 and abuts against the two groups of second limiting plates. The lower lifting arm 2 limits the upper lifting arm 1 through the second limiting plates 42, restricting the relative displacement between the upper lifting arm 1 and the lower lifting arm 2 along the width direction of the upper lifting arm 1 itself.

[0034] Refer to Figure 1 , the upper lifting arm 1 and the lower lifting arm 2 are locked to each other through the connecting mechanism. Thus, when the lower lifting arm 2 drives the upper lifting arm 1 to move, the lower lifting arm 2 can be kept perpendicular to the upper lifting arm 1, which is beneficial to improving the connection stability between the upper lifting arm 1 and the lower lifting arm 2. And when disassembling the lower lifting arm 2 and the upper lifting arm 1, the upper lifting arm 1 can be directly taken away from the lower lifting arm 2 vertically, which is more convenient during disassembly.

[0035] Refer to Figure 1 , hook connection parts one 11 are provided at both ends of the upper lifting arm 1 along the length direction, and the two hook connection parts one 11 are both located at the lower end of the upper lifting arm 1. When it is necessary to hoist a wind power pile, the main hoisting ropes are hung at the lower ends of the two hook connection parts one 11. Hoisting ears are provided on both sides of the wind power pile along the transverse direction, and the ends of the two main hoisting ropes far away from the hook connection parts one 11 are respectively connected to the two hoisting ears.

[0036] Refer to Figure 1 , an auxiliary hook 22 is provided at the lower end of the lower lifting arm 2. The plane where the auxiliary hook 22 is located in the length direction of the upper lifting arm 1 is hinged to the lower lifting arm 2, and two hanging blocks 221 are fixedly connected to the end of the auxiliary hook 22 far away from the lower lifting arm 2. The two hanging blocks 221 are symmetrically arranged with the axis of the auxiliary hook 22 as the center. A groove is provided at the end of the hanging block 221 close to the lower lifting arm 2. The auxiliary hook 22 is connected to an auxiliary hoisting rope, and one end of the auxiliary hoisting rope is connected to and locked with a hoisting mechanism. The hoisting mechanism can specifically be a crane, and a tightening mechanism for fixing the auxiliary hoisting rope is installed on one side of the crane, such as a winch.

[0037] Refer to Figure 1, one end of the auxiliary lifting rope far away from the tightening mechanism is fixedly connected with a trailing hook, which is connected to one end of the wind power pile far away from the lifting lug through the trailing hook. At this time, the lifting mechanism drives the lower boom 2 and the upper boom 1 to lift, and then drives the wind power pile to translate through the two main lifting ropes and the auxiliary lifting rope. When the end of the wind power pile installed with the trailing hook moves to the preset position and the lower end of the wind power pile contacts the installation area, the tightening mechanism drives the auxiliary lifting rope to relax, and the hoisting mechanism is manipulated to drive the upper boom 1 and the lower boom 2 to lift, and then the wind power pile is gradually inclined through the two main lifting ropes.

[0038] Refer to Figure 1 , when the wind power pile is flipped to the established angle, the trailing hook disengages from the wind power pile. The trailing hook is a prior art and will not be elaborated here. A hook release mechanism is provided on the auxiliary hook 22. The operator makes the auxiliary lifting rope disengage from the hanging block 221 through the hook release mechanism, and recovers the auxiliary lifting rope and the trailing hook. When the wind power pile is flipped to the vertical state, the hoisting mechanism stops moving and disengages the main lifting rope from the lifting lug, thereby completing the turning over of the wind power pile. When flipping the wind power pile, there is no need to separately select slings, which is more convenient when hoisting and flipping the wind power pile.

[0039] Refer to Figure 2 and Figure 3 , the hook release mechanism includes a driving block 36, a driven block 37 and a connecting rope 38. The lower boom 2 is fixedly connected with a guide rail 25 along the vertical direction. The guide rail 25 is arranged in the direction from the upper boom 1 to the lower boom 2. The driving block 36 and the driven block 37 are both slidably connected with the guide rail 25 along the length direction of the guide rail 25, and the driven block 37 is located on the side of the driving block 36 close to the auxiliary hook 22. An elastic member III 361 is provided between the driving block 36 and the driven block 37. The elastic member III 361 is a spring. One end of the spring is fixedly connected with the driving block 36, and the other end is fixedly connected with the driven block 37. When a relative displacement occurs between the driving block 36 and the driven block 37, the elastic member III 361 deforms.

[0040] Refer to Figure 2 and Figure 3 , one end of the connecting rope 38 is fixedly connected with the driving block 36. A turning wheel 253 is rotatably connected to the upper end of the guide rail 25 along the vertical direction. The end of the connecting rope 38 far away from the driving block 36 is wound around the turning wheel 253 upward and extends downward. A lifting rope connecting member 381 is provided at the end of the connecting rope 38 far away from the driving block 36. The lifting rope connecting member 381 is a clamp. Before hoisting the wind power pile, the clamp is connected to any one of the main lifting ropes. When the main lifting rope is connected to the wind power pile and tightened, the connecting rope 38 is driven to stretch under the action of the lifting rope connecting member 381. Through the supporting action of the turning wheel 253, when the connecting rope 38 stretches, it drives the driving block 36 to move in the direction away from the auxiliary hook 22.

[0041] Refer to Figure 3 and Figure 4The guide rail 25 is provided with a limit piece. In the initial state, the driven block 37 is located on the side of the guide rail 25 close to the auxiliary hook 22. The limit piece includes a translation block 391, a push block 392, an elastic member 394 and a disassembly rope 393. The translation block 391 is located on the side of the guide rail 25 close to the auxiliary hook 22 and is slidably connected to the guide rail 25 along the length direction of the lower boom 2. The guide rail 25 is provided with a transverse groove 251 in the transverse direction. The translation block 391 is fixedly connected with a sliding block 395 adapted to the transverse groove 251. The sliding block 395 is located in the transverse groove 251 and is slidably connected to the guide rail 25 along the length direction of the transverse groove 251.

[0042] Reference Figure 3 and Figure 4 , an elastic member 394 is provided in the transverse groove, and the elastic member 394 is a spring. The spring is located on the side of the sliding block 395 away from the driven block 37, and one end of the spring is fixedly connected to the sliding block 395, and the other end is fixedly connected to the guide rail 25. The elastic member 3 361 is in a compressed state, and applies a thrust to the sliding block 395 to approach the driven block 37. The side of the driven block 37 away from the lower boom 2 is fixedly connected with a fixed block 371. When the driven block 37 is in a position close to the auxiliary hook 22, the fixed block 371 is located on the side of the translation block 391 away from the active block 36. When the active block 36 is away from the auxiliary hook 22 under the action of the connecting rope 38, a pulling force is applied to the driven block 37 through the elastic member 3 361, so that the driven block 37 has a tendency to move away from the auxiliary hook 22.

[0043] Reference Figure 3 and Figure 4 When the driven block 37 moves, it drives the fixed block 371 to contact the translation block 391. Under the limiting action of the transverse groove 251 and the sliding groove, the translation block 391 limits the fixed block 371, thereby preventing the driven block 37 from approaching the active block 36. When the connecting rope 38 is tensioned, the active block 36 is at the end of the guide rail 25 away from the auxiliary hook 22. Since the driven block 37 is limited by the translation block 391, the elastic member 361 is in a stretched state at this time.

[0044] Reference Figure 3 and Figure 4, a vertical groove 252 communicating with the transverse groove 251 is formed in the guide rail 25 along the length direction. The pushing block 392 is located in the vertical groove 252 and is slidably connected to the guide rail 25 along the length direction of the vertical groove 252. One end of the disassembly rope 393 is fixedly connected to the pushing block 392. A supporting wheel 254 is also rotatably connected to the upper end of the guide rail 25 in the vertical direction. The end of the disassembly rope 393 away from the pushing block 392 is wound around the supporting wheel 254 and extends to the position where the operator is located along the hoisting mechanism. Under the action of the supporting wheel 254, when the operator pulls the disassembly rope 393, the disassembly rope 393 drives the pushing block 392 to move away from the auxiliary hook 22. One end of the pushing block 392 away from the auxiliary hook 22 is provided with a guiding surface, and one end of the sliding block 395 close to the fixed block 371 is provided with an inclined surface adapted to the guiding surface.

[0045] Refer to Figure 3 and Figure 4 , in the initial state, the pushing block 392 is located on the side of the guide rail 25 close to the auxiliary hook 22. At this time, the guiding surface of the pushing block 392 faces the inclined surface of the sliding block 395. When the guiding surface of the pushing block 392 contacts the inclined surface of the sliding block 395, the pushing block 392 pushes the sliding block 395 to move away from the fixed block 371 through the guiding surface, so that the translation block 391 is separated from the fixed block 371.

[0046] Refer to Figure 3 and Figure 5 , the hook - disengaging mechanism further includes a pulling rope 31, a jacking plate 32, a first elastic member 33 and a flipping plate 34. The jacking plate 32 is slidably connected to the auxiliary hook 22 along the length direction of the auxiliary hook 22. One end of the pulling rope 31 is fixedly connected to the jacking plate 32, and the other end is fixedly connected to the driven block 37. When the jacking plate 32 is at the end of the auxiliary hook 22 away from the lower boom 2, the driven block 37 is at the end of the guide rail 25 close to the auxiliary hook 22.

[0047] Refer to Figure 3 and Figure 5 , a connecting plate 321 is vertically fixed to the end of the jacking plate 32 away from the lower boom 2. In the initial state, the connecting plate 321 is located on the side of the upper groove of the hanging block 221 away from the lower boom 2. When the auxiliary lifting rope is placed in the groove, the connecting plate 321 does not contact the auxiliary lifting rope. The flipping plate 34 is located at the upper end of the connecting plate 321, and one end of the flipping plate 34 away from the jacking plate 32 is hinged to the connecting plate 321 in the vertical direction. The first elastic member 33 is a torsion spring. One end of the torsion spring is fixedly connected to the flipping plate 34, and the other end is fixedly connected to the connecting plate 321. When the flipping plate 34 and the jacking plate 32 are in a vertical state, the torsion spring is in a deformed state and has a tendency to drive the flipping plate 34 to flip away from the jacking plate 32.

[0048] Refer to Figure 2 and Figure 5, the auxiliary hook 22 is provided with a positioning member. The positioning member includes a rotating shaft 231 and a hinged plate 232. The hinged plate 232 is located at one end of the turning plate 34 close to the lifting plate 32 and is vertically hinged to the turning plate 34. The rotating shaft 231 is located at the end of the hinged plate 232 away from the turning plate 34, and the rotating shaft 231 passes through the hinged plate 232 and is rotatably connected to the hinged plate 232. The auxiliary hook 22 is vertically provided with a straight groove 241 and an arc groove 242 from bottom to top. When the connecting plate 321 is at the end of the auxiliary hook 22 away from the lower boom 2, the rotating shaft 231 is located in the straight groove 241 and abuts against the inner wall of the straight groove 241. At this time, the auxiliary hook 22 limits the rotating shaft 231 through the straight groove 241, and further the rotating shaft 231 restricts the turning plate 34 through the hinged plate 232. At this time, the turning plate 34 and the hinged plate 232 are in the same straight line and are both perpendicular to the lifting plate 32.

[0049] Refer to Figure 2 and Figure 5 , one end of the lifting plate 32 close to the lower boom 2 is vertically hinged with a baffle 35. One end of the baffle 35 close to the lifting plate 32 is fixedly connected with a contact block 351. When the baffle 35 rotates, it drives the contact block 351 to move. The lifting plate 32 is fixedly connected with a limit block 323 corresponding to the contact block 351. When the contact block 351 contacts the limit block 323, the baffle 35 is opposite to the hanging block 221. An elastic member II 322 is provided between the baffle 35 and the lifting plate 32. The elastic member II 322 is a torsion spring. One end of the torsion spring is fixedly connected with the baffle 35, and the other end is fixedly connected with the lifting plate 32. When the elastic member II 322 is in the natural state, the contact block 351 contacts the limit block 323.

[0050] Refer to Figure 2 and Figure 5 , when it is necessary to put the auxiliary lifting rope into the groove of the hanging block 221, rotate the baffle 35 towards the connecting plate 321 to make the baffle 35 avoid the auxiliary lifting rope. After the auxiliary lifting rope enters the groove, the baffle 35 resets under the action of the elastic member II 322. At this time, the baffle 35 blocks the auxiliary lifting rope, thereby preventing the auxiliary lifting rope from detaching from the groove, which is beneficial to improving the connection stability between the auxiliary lifting rope and the hanging block 221.

[0051] Refer to Figure 2 and Figure 5 , when it is necessary to take out the auxiliary lifting rope from the groove, the operator pulls the disassembly rope 393, thereby releasing the limit on the driven block 37. Under the action of the elastic member III 361, the driven block 37 moves away from the auxiliary hook 22. When the driven block 37 moves, it drives the pull rope 31 to move, so that the pull rope 31 drives the lifting plate 32 to approach the upper boom 1. When the lifting plate 32 moves, it drives the baffle 35 away from the hanging block 221, thereby releasing the limit of the baffle 35 on the auxiliary lifting rope.

[0052] Refer toFigure 2 and Figure 5 When the lifting plate 32 moves, it drives the connecting plate 321 and the flipping plate 34 to move. When the flipping plate 34 contacts the auxiliary lifting rope, it pushes the auxiliary lifting rope to move away from the hanging block 221. When the flipping plate 34 moves, it drives the hinge plate 232 and the rotating shaft 231 to move synchronously. After the rotating shaft 231 enters the arc-shaped groove 242 along the straight groove 241, it moves along the arc-shaped groove 242 away from the lifting plate 32, and then drives the flipping plate 34 to flip through the hinge block. At the same time, the first elastic member 33 applies a torsional force to the flipping plate 34, further improving the convenience when the flipping plate 34 flips. After the flipping plate 34 flips, it is in an inclined state, so that the auxiliary lifting rope slides along the inclined flipping plate 34 to complete the unhooking of the auxiliary lifting rope.

[0053] Refer to Figure 2 and Figure 5 The lower end of the pushing block 392 is fixedly connected with a top plate 396. The top plate 396 faces the side of the fixed block 371 close to the auxiliary hook 22. When the sling connecting member 381 moves relative to the corresponding main sling, resulting in insufficient deformation of the third elastic member 361, the pushing block 392 is driven to move along the guide rail 25 through the disassembly rope 393, so that the top plate 396 contacts the fixed block 371 and pushes the fixed block 371 to move away from the auxiliary hook 22, causing the fixed block 371 to drive the driven block 37 to move and drive the pulling rope 31 to move, completing the unhooking of the auxiliary lifting rope.

[0054] The working principle of the offshore wind power pile hoisting and turning tooling in the embodiment of the present application is as follows: When it is necessary to turn the wind power pile, first connect the lifting mechanism to the two hook connection parts 21 through the sling, so as to facilitate lifting the lower boom 2. The lower boom 2 is connected to the upper boom 1 through the connecting mechanism, and when the lower boom 2 moves, it drives the upper boom 1 to move. Connect the two hook connection parts 11 of the upper boom 1 to the lifting lugs on both sides of the wind power pile through the main sling. Finally, connect the auxiliary sling to the auxiliary hook 22, and hook the tailing hook on the auxiliary sling to the end of the wind power pile. During hoisting, the wind power pile is lifted by the cooperation of the main sling and the auxiliary sling. When the wind power pile is horizontally moved to the preset position, gradually loosen the auxiliary sling and continue to lift the upper boom 1, so that the wind power pile gradually flips until the tailing hook is separated from the wind power pile. Then, the auxiliary sling is driven to leave the auxiliary hook 22 through the unhooking mechanism, and continue to lift the upper boom 1 until the wind power pile is erected, completing the flipping of the wind power pile. There is no need to select slings when hoisting and flipping the wind power pile, and the flipping operation is more convenient.

[0055] The embodiment of the present application also discloses a turning method for an offshore wind power pile hoisting and turning tooling, including the following steps: Positioning, the transport ship and the crane ship drop anchor and position at the designated position and maintain relative stability; Select the lifting ropes, and connect the two hook connection parts II 21 above the lower boom to the lifting mechanism of the crane vessel through the lifting ropes, so that the lifting mechanism lifts the lower boom 2 and the upper boom 1; Select the main lifting ropes, and connect the two hook connection parts I 11 on the upper boom 1 to the lifting lugs on both sides of the wind power pile respectively through the main lifting ropes; Select the auxiliary lifting rope, suspend the auxiliary lifting rope below the auxiliary hook 22, and connect the lower end of the auxiliary lifting rope to the trailing hook. Connect the trailing hook to the end of the wind power pile; Lift. The lifting mechanism lifts the lower boom 2. When the lower boom 2 moves, it lifts the wind power pile through the upper boom 1. After the wind power pile leaves the transport ship, the transport ship sails away from the crane vessel; Unhook. Continuously lift the wind power pile until the trailing hook is unhooked from the wind power pile, then disconnect the auxiliary lifting rope from the auxiliary hook 22 through the unhooking mechanism, and then continuously lift the wind power pile to the vertical until the pile turning is completed.

[0056] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
