Technical Field
[0001] The present invention relates to the field of hoisting of steel pipe piles, and in particular to a single-hook hoisting structure for an ultra-large steel pipe pile tailing hook using a secondary hook to release the hook. Background Art
[0002] Traditional power generation methods use fossil energy combustion for power generation. With the gradual depletion of global fossil energy and the severe situation of climate change, power generation methods using clean energy have received attention. Among them, wind energy, as a renewable and clean energy with little environmental impact, has become increasingly prominent in value, and the transformation and development of large-scale wind power generation has become an inevitable trend, such as mountaintop wind power generation, offshore wind power generation, etc.
[0003] Offshore wind power generation belongs to a new market industry and is gradually developing towards the open sea. During the construction of a wind farm, it is necessary to assemble offshore steel pipe piles in deep waters. The traditional method is to use a full-rotation crane ship to adopt a double-hook hoisting mode with a main hook and a secondary hook. However, when encountering offshore steel pipe piles with large weight and long length, the double-hook hoisting mode is not applicable, and at this time, the hoisting weight requirement cannot be met.
[0004] The present application provides a single-hook hoisting structure for an ultra-large steel pipe pile tailing hook using a secondary hook to release the hook, which can not only meet the hoisting weight requirement but also solve the problem of releasing the hook of the ultra-long steel pipe pile tailing hook. Summary of the Invention
[0005] In order to meet the hoisting weight requirements of ultra-large steel pipe piles with large weight and long length, the present application provides a single-hook hoisting structure for an ultra-large steel pipe pile tailing hook using a secondary hook to release the hook.
[0006] The single-hook hoisting structure for an ultra-large steel pipe pile tailing hook using a secondary hook to release the hook provided by the present application adopts the following technical solutions:
[0007] A single-hook hoisting structure for an ultra-large steel pipe pile tailing hook using a secondary hook to release the hook, comprising:
[0008] A main hook, the main hook is connected with a main lifting lug steel wire rope, and the end of the main lifting lug steel wire rope away from the main hook is used for connecting the lifting lug of the steel pipe pile;
[0009] A tailing hook steel wire rope, the tailing hook steel wire rope is connected to the main hook, and the end of the tailing hook steel wire rope away from the main hook is used for connecting the bottom of the steel pipe pile;
[0010] A secondary hook, the secondary hook is connected with a hook-release steel wire rope, and the end of the hook-release steel wire rope away from the secondary hook is connected to the tailing hook steel wire rope;
[0011] When the bottom of the steel pipe pile touches the ground, the secondary hook lifts the hook-release steel wire rope, and the tailing hook steel wire rope disengages from the main hook and separates from the bottom of the steel pipe pile.
[0012] By adopting the above technical solution, at the beginning, both the main lifting lug wire rope and the tailing hook wire rope are connected to the main hook. After waiting for the bottom of the steel pipe pile to touch the ground and keeping the tailing hook wire rope unloaded, the auxiliary hook is used to lift the unhooking wire rope. The tailing hook wire rope disengages from the main hook and moves away from the bottom of the steel pipe pile. At this time, only the main lifting lug wire rope is connected to the lifting lug of the steel pipe pile. The main hook is used to slowly lift the steel pipe pile until the steel pipe pile is in a vertical state for construction. This single-hook lifting structure can not only meet the lifting weight requirements but also solve the problem of unhooking the tailing hook of the ultra-long steel pipe pile.
[0013] Optionally, the main hook is divided into a main hook and a cross hook. The cross hook is connected to the bottom of the main hook. The cross hook includes two first hooks and two second hooks arranged oppositely. The main lifting lug wire rope is connected to the first hook, and the tailing hook wire rope is connected to the second hook.
[0014] By adopting the above technical solution, the cross hook facilitates the connection of the main lifting lug wire rope and the tailing hook wire rope, enabling the three-point simultaneous lifting of the steel pipe pile by the main hook during the lifting process.
[0015] Optionally, both the first hook and the second hook are formed with hanging grooves, and both the main lifting lug wire rope and the tailing hook wire rope are hung in the hanging grooves.
[0016] By adopting the above technical solution, the setting of the hanging grooves facilitates the hanging connection of the main lifting lug wire rope and the tailing hook wire rope and also facilitates the disengagement of the tailing hook wire rope from the second hook.
[0017] Optionally, two main lifting lug wire ropes are provided and are respectively connected to the two lifting lugs of the steel pipe pile. A strut beam is arranged between the two main lifting lug wire ropes.
[0018] By adopting the above technical solution, the two main lifting lug wire ropes and the strut beam ensure the stability of both ends of the steel pipe pile during the lifting process, resulting in better stability.
[0019] Optionally, a turning clamp is connected to the end of the tailing hook wire rope away from the second hook, and the turning clamp is used to clamp the bottom of the steel pipe pile.
[0020] By adopting the above technical solution, the turning clamp is used to realize the connection between the tailing hook wire rope and the bottom of the steel pipe pile.
[0021] Optionally, the turning clamp is provided with a clamping groove, and the clamping groove is clamped on the bottom of the steel pipe pile.
[0022] By adopting the above technical solution, the clamping connection through the clamping groove enhances the stability of the connection between the turning clamp and the steel pipe pile.
[0023] Optionally, the turning pliers are connected with a snap ring, and the tailing hook steel wire rope is connected with the turning pliers through the snap ring.
[0024] By adopting the above technical solution, the snap ring is used to connect the tailing hook steel wire rope, and the position and deviation direction of the steel pipe pile can be towed and swung.
[0025] Optionally, both the main hook and the auxiliary hook are connected with the boom of the crane ship through suspension ropes.
[0026] By adopting the above technical solution, the crane ship can control the main hook and the auxiliary hook.
[0027] In summary, the present application has the following beneficial effects:
[0028] At the beginning, both the main lifting lug steel wire rope and the tailing hook steel wire rope are connected to the main hook. After waiting for the bottom of the steel pipe pile to land, when the tailing hook steel wire rope is not stressed, the auxiliary hook is used to lift the unhooking steel wire rope, and the tailing hook steel wire rope disengages from the main hook. The tailing hook steel wire rope moves away from the bottom of the steel pipe pile. At this time, only the main lifting lug steel wire rope is connected to the lifting lug of the steel pipe pile. The main hook is used to slowly lift the steel pipe pile until the steel pipe pile is in a vertical state for construction. This single-hook lifting structure can not only meet the lifting weight requirements but also solve the problem of unhooking the tailing hook of the ultra-long steel pipe pile.

[0034] The following is a further detailed description of the present application in conjunction with the attached Figures 1-3 to the present application.
[0035] The embodiment of the present application discloses a single-hook lifting structure for unhooking the tailing hook of an ultra-large steel pipe pile by using an auxiliary hook. Refer to Figures 1-3A single hook lifting structure of a super large steel pipe pile tail hook with auxiliary hook unhooking includes a main hook 2 and an auxiliary hook 5, both of which are connected to the arm of a crane ship through a suspension rope 8, the main hook 2 is connected with a main lifting eye 11 steel wire rope and a tail hook steel wire rope 4, and the auxiliary hook 5 is connected with a unhooking steel wire rope 51. The end of the unhooking steel wire rope 51 away from the auxiliary hook 5 is connected to the tail hook steel wire rope 4, the end of the tail hook steel wire rope 4 away from the main hook 2 is connected to the bottom of the steel pipe pile 1, and the end of the main lifting eye 11 steel wire rope away from the main hook 2 is connected to the lifting eye 11 of the steel pipe pile 1. The auxiliary hook 5 can drive the tail hook steel wire rope 4 to disengage from the main hook 2 by lifting the unhooking steel wire rope 51, so as to realize the single hook lifting of the main hook 2.
[0036] When hoisting the super-large steel pipe pile 1, the arm of the crane ship drives the main hook 2 to move, and the steel pipe pile 1 is lifted by three-point lifting, and the steel pipe pile 1 is slowly sunk to the seabed. When the bottom of the steel pipe pile 1 touches the ground, it is ensured that the tail hook wire rope 4 is not stressed and the main lifting ear 11 wire rope is stressed, and the auxiliary hook 5 lifts the unhooking wire rope 51 upward, drives the tail hook wire rope 4 to detach from the main hook 2, and recycles the tail hook wire rope 4. Then, the steel pipe pile 1 is slowly lifted by the main hook 2 wire rope until the steel pipe pile 1 is in a vertical state, and pile sinking construction can be carried out at this time. The hoisting method of the present application can not only meet the lifting requirements, but also solve the problem of the tail hook detaching from the super-long steel pipe pile 1.
[0037] The main hook 2 is divided into a main hook 21 and a cross hook 22, and the cross hook 22 is connected to the bottom of the main hook 21. The cross hook 22 is in the shape of a "cross", including two first hooks 6 and two second hooks 61 arranged opposite to each other, and the first hook 6 and the second hook 61 are both formed with a hanging groove 62. Two main lifting ears 11 steel wire ropes are provided and are respectively hung in the hanging groove 62 of the first hook 6, and the tail hook steel wire rope 4 is hung in the hanging groove 62 of the second hook 61. The arrangement of the cross hook 22 and the hanging groove 62 facilitates the connection and disconnection of the main lifting ears 11 steel wire rope and the tail hook steel wire rope 4. A support beam 31 is arranged between the two main lifting ears 11 steel wire ropes, and the support beam 31 is used to maintain the balance between the two main lifting ears 11 steel wire ropes, so that the steel pipe pile 1 is more stable and more stable during the lifting process.
[0038] The end of the tail hook wire rope 4 away from the second hook 61 is connected to a turning clamp 7, and the turning clamp 7 is provided with a clamping groove 72 and a buckle 71. The clamping groove 72 is clamped at the bottom of the steel pipe pile 1, and the buckle 71 is used to connect with the tail hook wire rope 4, so as to achieve the connection between the tail hook wire rope 4 and the steel pipe pile 1. When the tail hook wire rope 4 is separated from the second hook 61, the turning clamp 7 and the bottom of the steel pipe pile 1 can be separated, so that the tail hook wire rope 4 can be recovered, and the mode in which only the main lifting eye 11 wire rope is connected to the lifting eye 11 of the steel pipe pile 1 is restored.
[0039] The implementation principle of a single-hook lifting structure with a secondary hook decoupling for the super-large steel pipe pile tail chute hook in the embodiments of this application is as follows: When hoisting the super-large steel pipe pile 1,
[0040] 1. Hook the steel pipe pile 1 on the deck of the crane ship. Connect the wire rope of the main lifting lug 11 to the lifting lug 11 of the steel pipe pile 1. Hang the wire rope of the main lifting lug 11 on the first hook 6. Hang the wire rope 4 of the tail chute hook on the second hook 61 and connect it to the wire rope 51 for decoupling. Hang the wire rope 51 for decoupling on the secondary hook 5 and keep it in a slack state;
[0041] 2. Lift the steel pipe pile 1 and slowly sink the steel pipe pile 1 into the seabed. Keep the wire rope 51 for decoupling in a slack state before the bottom of the steel pipe pile 1 touches the ground;
[0042] 3. After the bottom of the steel pipe pile 1 touches the ground, ensure that the wire rope 4 of the tail chute hook is not stressed. After the wire rope of the main lifting lug 11 is stressed, the secondary hook 5 lifts the wire rope 51 for decoupling upward. After the wire rope 4 of the tail chute hook disengages from the first hook 6, the main hook 2 slowly lifts the steel pipe pile 1, and the secondary hook 5 slowly lowers the wire rope 4 of the tail chute hook until the turning clamp 7 disengages from the bottom of the steel pipe pile 1, then recover the wire rope 4 of the tail chute hook;
[0043] 4. The main hook 2 slowly lifts the steel pipe pile 1 until it is in a vertical state, and then it can enter the pile-holding and pile-stabilizing platform for pile sinking construction. This specific implementation manner is only an explanation of this application and is not a limitation of this application. Those skilled in the art can make modifications without creative contributions to this specific implementation manner according to needs after reading this specification, but as long as it is within the scope of the claims of this application, it is protected by the patent law.
