Description

Technical Field

[0001] This application relates to the field of shipboard hoisting technology, specifically to hoisting devices and ships used for wind power installation. Background Technology

[0002] In related technologies, as offshore wind power develops towards deep-sea areas, the leg length of jack-up wind turbine installation vessels cannot meet the needs of wind turbine installation in deep-water wind farms. Furthermore, for wind farms with soft seabeds, the large mud penetration depth of the legs of jack-up wind turbine installation vessels increases the construction risk. Therefore, a wind turbine hoisting equipment suitable for deep-sea marine environments has been developed. This equipment needs to overcome the ship movement caused by marine hydrological conditions, provide a relatively stable installation environment, and meet the docking requirements during the on-site wind turbine installation process.

[0003] For controlling the installation position of wind turbines and other components, the ship's own DP system (Dynamic Positioning System) controls the planar coordinates, and the docking buffer system can reduce the docking impact load caused by the ship's heave and the lowering of the hook. However, it cannot control the adjustment of the vertical attitude of wind turbines and other components, which reduces assembly efficiency. Summary of the Invention

[0004] This application provides a wind power installation vessel lifting device and vessel, which can adjust and control the vertical attitude of the assembly components to improve assembly efficiency.

[0005] On one hand, this application provides a lifting device for a wind power installation vessel, including a support frame, a first clamp assembly, a second clamp assembly, and multiple telescopic assemblies. The upper part of the support frame is provided with a lifting assembly for lifting assembly components, and the lower part of the support frame is provided with a support portion and a first drive component. The first clamp assembly is disposed on the support frame and located above the support portion. Multiple telescopic assemblies are arranged at intervals along the circumference of the assembly components. The first ends of each telescopic assembly are connected to the drive end of the first drive component and are slidably connected to the support portion along a first direction. The second clamp assembly is hinged to the second ends of the multiple telescopic assemblies, and the multiple telescopic assemblies can adjust the displacement of the second clamp assembly along a second direction. The first direction, the second direction, and the height direction of the support frame intersect each other.

[0006] Beneficial effects: The second clamp assembly slides back and forth with the support in the first direction through multiple telescopic components, and adjusts the displacement of the second clamp in the second direction through the telescopic cooperation of multiple telescopic components, thereby counteracting the tilt of the assembly parts caused by the swaying of the waves, thus ensuring the vertical posture of the assembly parts and improving assembly efficiency.

[0008] In one alternative embodiment, the number of telescopic components is two, and the two telescopic components are evenly arranged along the circumference of the assembly component.

[0010] In one optional embodiment, the telescopic assembly further includes a rotating sleeve, which is hinged to the second end of the telescopic member. The hinge axes of the rotating sleeve and the sliding groove body with the telescopic member are both parallel to the first direction. The rotating sleeve is hinged to the second clamp assembly, and the hinge axis of the rotating sleeve and the second clamp assembly is parallel to the second direction.

[0011] In an alternative implementation, a controller is further included, which is electrically connected to the first drive component and the plurality of telescopic components.

[0012] In one optional embodiment, the first clamp assembly includes a first arc frame, a second arc frame, a third arc frame, and a plurality of first hydraulic cylinders.

The second ends of the second arc frame and the second ends of the third arc frame can open and close to fix the assembly component. At least one first hydraulic cylinder is provided on each of the first arc frame, the second arc frame, and the third arc frame to radially limit the assembly component.

[0013] And / or, the second clamp assembly includes a fourth arc-shaped frame, a fifth arc-shaped frame, a sixth arc-shaped frame, and a plurality of second hydraulic cylinders. The fourth arc-shaped frame is hinged to a plurality of the telescopic components. The first end of the fifth arc-shaped frame and the first end of the sixth arc-shaped frame are respectively hinged to the two ends of the fifth arc-shaped frame. The second end of the fifth arc-shaped frame and the second end of the sixth arc-shaped frame can open and close to fix the assembly component. At least one second hydraulic cylinder is provided on each of the fourth arc-shaped frame, the fifth arc-shaped frame, and the sixth arc-shaped frame to radially limit the assembly component.

[0014] In one alternative implementation, the first direction, the second direction, and the height direction of the support frame are arranged perpendicularly to each other.

[0015] In one optional embodiment, a lower lifting component is further included, which is disposed on the support portion. The telescopic end of the lower lifting component slides back and forth along the height direction of the support frame for connection with the assembly component.

[0016] On the other hand, this application also provides a vessel, including: the wind power installation vessel lifting device described in any one of the above.

[0017] Beneficial effects: Since the ship includes a wind turbine installation vessel lifting device, it has the same technical effects as the wind turbine installation vessel lifting device, so it will not be elaborated here. Attached Figure Description

[0039] In related technologies, as offshore wind power develops towards deep-sea areas, the leg length of jack-up wind turbine installation vessels cannot meet the needs of wind turbine installation in deep-water wind farms. Furthermore, for wind farms with soft seabeds, the large mud penetration depth of the legs of jack-up wind turbine installation vessels increases the construction risk. Therefore, a wind turbine hoisting equipment suitable for deep-sea marine environments has been developed. This equipment needs to overcome the ship movement caused by marine hydrological conditions, provide a relatively stable installation environment, and meet the docking requirements during the on-site wind turbine installation process.

[0040] For controlling the installation position of wind turbines, the ship's own DP system (Dynamic Positioning System) is used to control the planar coordinates. The docking buffer system can reduce the docking impact load caused by the ship's heave and the lowering of the hook. However, the vertical attitude adjustment of the wind turbines cannot be controlled, which reduces the assembly efficiency.

[0041] To address the aforementioned issues, this application provides a wind power installation vessel lifting device and vessel, which can adjust and control the vertical attitude of the assembled components, thereby improving assembly efficiency.

[0042] The following is combined Figures 1 to 10 This describes an embodiment of the present application.

[0043] According to embodiments of this application, in one aspect, a wind power installation vessel lifting device is provided, such as... Figure 1 As shown, it includes a support frame 1, a first clamp assembly 2, a second clamp assembly 4, and multiple telescopic components 3, with the specific scheme as follows.

[0044] like Figure 1 As shown, the support frame 1 is a frame made of multiple steel pipes welded together, or it can be a frame made of multiple steel frames assembled together. The upper part of the support frame 1 is provided with a hoisting assembly 11 for hoisting the assembly component 6. Specifically, the assembly component 6 can be a wind turbine unit or other components used for offshore hoisting. The lower part of the support frame 1 is provided with a support part 12 and a first drive component. Specifically, the first drive component is a hydraulic cylinder with telescopic function, or it can be a motor connected to a lead screw, or it can be a motor with a gear and rack, etc.

[0045] like Figure 1 and Figure 8 As shown, the first clamp assembly 2 is installed on the support frame 1 by bolting or welding, and is located above the support part 12. It is used to limit the upper part of the assembly component 6. The assembly component 6 can rotate relative to the first clamp assembly 2, that is, the angle between the assembly component 6 and the central axis of the first clamp remains stable. Specifically, the distance between the first clamp assembly 2 and the support part 12 can be set according to the length of the assembly component 6 to be hoisted. Generally, the distance between the two is 50% to 90% of the length of the assembly component 6, preferably 80% or 85%.

[0046] like Figures 2 to 5 As shown, the telescopic component 3 is a component with telescopic function, such as a telescopic cylinder or a motor with a lead screw; multiple telescopic components 3 are arranged at intervals along the circumference of the assembly component 6, and the first end of each of the multiple telescopic components 3 is fixedly connected to the driving end of the first driving component by bolts, or can be hinged by a hinge shaft, and is slidably connected to the support part 12 along the first direction X.

[0047] Specifically, the number of telescopic components 3 can be 2 to 6, preferably, such as... Figure 4 and Figure 5As shown, there are two telescopic components 3, which are evenly arranged around the circumference of the assembly part 6; or there can be four, arranged in a square array; as for the connection between the telescopic components 3 and the support part 12 and the second clamp assembly 4, a spherical hinge joint can be used.

[0048] like Figure 2 and Figure 3 As shown, the second clamp assembly 4 is hinged to the second ends of multiple telescopic components 3. The multiple telescopic components 3 can adjust the displacement of the second clamp assembly 4 along the second direction Y. The second clamp assembly 4 is used for radial fixed connection with the assembly component 6, that is, the included angle between the assembly component 6 and the central axis of the second clamp remains stable; wherein, as Figure 6 As shown, the first direction X, the second direction Y, and the height direction of the support frame 1 intersect each other. Specifically, the included angle between any two of the first direction X, the second direction Y, and the height direction of the support frame 1 can be any angle. Preferably, the first direction X, the second direction Y, and the height direction of the support frame 1 are set perpendicular to each other, that is, the first direction X is perpendicular to the second direction Y, the first direction X is perpendicular to the height direction of the support frame 1, and the second direction Y is perpendicular to the height direction of the support frame 1.

[0049] In specific usage, such as Figure 1 As shown, taking the hoisting of a wind turbine generator set by a wind turbine installation vessel as an example, the wind turbine generator set is hoisted by the hoisting assembly 11 on the support frame 1. The upper part of the wind turbine generator set is fixed by the first clamp assembly 2, and the lower part of the wind turbine generator set is fixed by the second clamp assembly 4. The DP system on the vessel realizes the control of the vessel's plane coordinates to ensure the stability of the vessel. However, due to the influence of wind and waves at sea, the vessel will sway, causing the wind turbine generator set to tilt.

[0050] The first drive component drives the first end of the telescopic component to reciprocate along the first direction X on the support 12, thereby causing the second clamp assembly 4 to reciprocate along the first direction X. Combined with the telescopic cooperation of the telescopic component 3 (i.e., a part of the telescopic component 31 extends and retracts, a part of the telescopic component 31 extends, or both extend and retract simultaneously), the second clamp assembly 4 moves along the second direction Y, thereby keeping the wind turbine in a vertical position and facilitating assembly.

[0051] In this embodiment, such as Figures 1 to 5 As shown, the second clamp assembly 4 reciprocates with the support part 12 along the first direction X through multiple telescopic components 3, and adjusts the displacement of the second clamp in the second direction Y through the telescopic cooperation of multiple telescopic components 3, thereby counteracting the tilt of the assembly part 6 caused by the swaying of the waves, thus ensuring the vertical posture of the assembly part 6 and improving assembly efficiency.

[0052] In one embodiment, such as Figure 2 and Figure 3 As shown, the second clamp assembly 4 is located below the support part 12, and the first ends of the multiple telescopic components 3 are all hinged to the support part 12, that is, the second clamp assembly 4 can swing and hang below the support part 12 along the second direction Y.

[0053] In actual use, the angle between the second clamp assembly 4 and the assembly component 6 remains stable. When the assembly component 6 tilts, by extending or retracting part of the telescopic component 31, or by extending or retracting simultaneously, the assembly component 6 located at the position of the second clamp assembly 4 can move in the opposite direction of the swaying. The second clamp assembly 4 is located below the support part 12, and the second clamp assembly 4 is in a downward pulling state on the support part 12, which facilitates the movement of the second clamp assembly 4 and facilitates the vertical posture adjustment of the assembly component 6.

[0054] In some embodiments not shown, the second clamp assembly 4 is located above the support portion 12, and the first ends of the plurality of telescopic components 3 are all hinged to the support portion 12, that is, the second clamp assembly 4 can swing along the second direction Y and is supported above the support portion 12 by the telescopic components 3.

[0055] In practical use, since the second clamp assembly 4 is located above the support part 12, and the second clamp assembly 4 is supported above the support part 12 by the telescopic assembly 3, although by extending and retracting part of the telescopic member 31, and extending and retracting part of the telescopic member 31, or extending and retracting at the same time, the assembly part 6 located at the position of the second clamp assembly 4 can move in the opposite direction of the sway to counteract the tilt caused by the sway of the hull, the second clamp assembly 4 is in a downward pressing state on the support part 12, resulting in poor structural stability, which will affect the moving accuracy of the second clamp assembly 4 and make it inconvenient to adjust the vertical attitude of the assembly part 6.

[0056] In one embodiment, such as Figure 6 As shown, the support frame 1 is provided with two support rods 121. The two support rods 121 are arranged in parallel and extend along the first direction X. The two support rods 121 are support parts 12. Specifically, the support rods 121 are connected to the support frame 1 by welding or bolting.

[0057] like Figures 2 to 5 As shown, the telescopic assembly 3 includes a telescopic component 31 and a sliding groove 32. The sliding groove 32 is slidably connected to the support rod 121. The first end of the telescopic component 31 is hinged to the sliding groove 32, and the second end of the telescopic component 31 is hinged to the second clamp assembly 4. Specifically, the telescopic component 31 is a telescopic cylinder. The sliding groove 32 is a metal block with a sliding groove to slide with the support rod 121. More specifically, the support rod 121 is provided with multiple rollers to reduce sliding friction.

[0058] In actual use, the slide body 32 is driven to connect with the first driving component, and the slide body 32 is driven to reciprocate relative to the support rod 121 through the telescopic end of the first driving component.

[0059] In this embodiment, the slide groove 32 is slidably connected to the support rod 121 along the first direction X, which has a simple structure and strong load-bearing capacity.

[0060] In one embodiment, such as Figures 2 to 5 As shown, the telescopic assembly 3 also includes a rotating sleeve 33, which is a metal sleeve. The rotating sleeve 33 is hinged to the second end of the telescopic member 31 via a rotating shaft. The hinge axes of the rotating sleeve 33 and the sliding groove body 32 to the telescopic member 31 are all parallel to the first direction X, thereby enabling the second clamp assembly 4 to sway along the second direction Y.

[0061] The rotating sleeve 33 is hinged to the second clamp assembly 4 via a rotating shaft. The hinge axis between the rotating sleeve 33 and the second clamp assembly 4 is parallel to the second direction Y, so that the second clamp assembly 4 can change its angle relative to the assembly part 6 during the reciprocating movement along the first direction X.

[0062] In this embodiment, the hinge axes of the rotating sleeve 33 and the slide body 32 with the telescopic member 31 are all parallel to the first direction X, and the hinge axis of the rotating sleeve 33 with the second clamp assembly 4 is parallel to the second direction Y. This facilitates the combined motion along the first direction X and the second direction Y to adjust the vertical posture of the assembly component 6 and simplify the calculation.

[0063] In one embodiment, the wind power installation vessel lifting device further includes a controller, which is electrically connected to the first drive component and multiple telescopic components 3. Specifically, the controller is a control module with data processing functions, such as a motherboard, a microcontroller, or a computing chip.

[0064] Specifically, the controller has a pre-set control program to send action commands to the first drive component and multiple telescopic components 3 to control the vertical posture of the assembly component 6.

[0065] In one embodiment (not shown), the controller is equipped with an adjustment model. A first displacement sensor is installed on the first clamp assembly 2, and a second displacement sensor is installed on the second clamp assembly 4. Before the first drive component and the multiple telescopic components 3 are activated, the first displacement sensor and the second displacement sensor can synchronously generate a first displacement signal and a second displacement signal. The controller can receive the first displacement signal and the second displacement signal and calculate the real-time relative displacement signal of the second displacement sensor relative to the first displacement sensor within a certain time period.

[0066] If at time N, the position signal of the first displacement sensor is (5,3) and the position signal of the second displacement sensor is (8,4), then the real-time relative displacement signal at time N is (3,1).

[0067] The controller acquires a periodic cyclic signal of the real-time relative displacement signal over a certain period of time. That is, the real-time relative displacement signal exhibits a periodic cycle over a certain period of time, which is due to the periodic cycle of wind and waves.

[0068] The controller obtains the periodic action signal with opposite displacement based on the periodic loop signal.

[0069] The controller decomposes the periodic action signal into a first periodic action signal executed by the first drive component and multiple second periodic action signals executed by multiple telescopic components 3.

[0070] The first drive component receives the first cycle action signal, and the multiple telescopic components 3 respectively receive multiple second cycle action signals, and then perform synchronous actions, which can effectively keep the assembly component 6 in a vertical posture.

[0071] In one embodiment, such as Figure 8 and Figure 9 As shown, the first clamp assembly 2 includes a first arc frame 21, a second arc frame 22, a third arc frame 23, and multiple first hydraulic cylinders 24. The first arc frame 21 is connected to the support frame 1 by bolts or welding. The first end of the second arc frame 22 and the first end of the third arc frame 23 are respectively hinged to the two ends of the second arc frame 22 by a pivot, and are driven to rotate by a second driving component. The second end of the second arc frame 22 and the second end of the third arc frame 23 can open and close to fix the assembly component 6. At least one first hydraulic cylinder 24 is provided on each of the first arc frame 21, the second arc frame 22, and the third arc frame 23 to radially limit the assembly component 6.

[0072] Specifically, such as Figure 9 As shown, the first hydraulic cylinder 24 is a hydraulic oil cylinder used to adapt to the radial limit of assembly parts 6 of different diameters. The number of first hydraulic oil cylinders is 3 to 6, preferably 4.

[0073] like Figure 6 and Figure 7As shown, the second clamp assembly 4 includes a fourth arc frame 41, a fifth arc frame 42, a sixth arc frame 43, and multiple second hydraulic cylinders 44. The fourth arc frame 41 is hinged to multiple telescopic components 3. The first ends of the fifth arc frame 42 and the sixth arc frame 43 are respectively hinged to the two ends of the fifth arc frame 42 and driven to rotate by the second driving component. The second ends of the fifth arc frame 42 and the sixth arc frame 43 can open and close to fix the assembly component 6. At least one second hydraulic cylinder 44 is provided on each of the fourth arc frame 41, the fifth arc frame 42, and the sixth arc frame 43 to radially limit the assembly component 6.

[0074] Specifically, such as Figure 7 As shown, the second hydraulic cylinder 44 is a constant pressure hydraulic cylinder, the number of the first hydraulic cylinders is 3 to 6, preferably 4, and the second driving component is a telescopic cylinder.

[0075] In this embodiment, by providing a first clamp assembly 2 and a second clamp assembly 4 that can be opened and closed, it is convenient to fix the assembly component 6. The assembly component 6 is fixed by multiple first telescopic hydraulic cylinders and multiple second telescopic hydraulic cylinders. The structure is simple and easy to operate.

[0076] In one embodiment, such as Figure 1 and Figure 10 As shown, the wind power installation vessel lifting device also includes a lower lifting component 5, which is mounted on the support 12. The telescopic end of the lower lifting component 5 slides back and forth along the height direction of the support frame 1 for connection with the assembly component 6.

[0077] Specifically, such as Figure 10 As shown, the lower lifting component 5 includes a pulley 51, a rope 52, and a fixed pulley 53. The pulley 51 is driven by a reduction motor, the fixed pulley 53 is fixed on the support part 12, one end of the rope 52 is wound around the pulley 51, and the other end of the rope 52 is connected to the assembly part 6 through the fixed pulley 53.

[0078] In this embodiment, by setting up the lower lifting component 5 and combining it with the hoisting assembly 11, the upper and lower parts of the assembly component 6 are hoisted simultaneously, which can improve the stability of the hoisting and prevent the assembly component 6 from deforming or being damaged.

[0079] The following example provides a comprehensive description of the ship lifting device for wind power installation.

[0080] This embodiment provides a lifting device for wind power installation vessels, such as... Figure 1 As shown, it includes a support frame 1, a first clamp assembly 2, a second clamp assembly 4, a controller, and multiple telescopic components 3, with the specific scheme as follows.

[0081] like Figure 1 As shown, the support frame 1 is a frame made of multiple steel pipes welded together, or it can be a frame made of multiple steel frames assembled together. The upper part of the support frame 1 is provided with a hoisting assembly 11 for hoisting the assembly component 6. Specifically, the assembly component 6 can be a wind turbine unit or other components used for offshore hoisting. The lower part of the support frame 1 is provided with a support part 12 and a first drive component. Specifically, the first drive component is a hydraulic cylinder with telescopic function, or it can be a motor connected to a lead screw, or it can be a motor with a gear and rack, etc.

[0082] like Figure 1 and Figure 8 As shown, the first clamp assembly 2 is installed on the support frame 1 by bolting or welding, and is located above the support part 12. It is used to limit the upper part of the assembly component 6. The assembly component 6 can rotate relative to the first clamp assembly 2, that is, the angle between the assembly component 6 and the central axis of the first clamp remains stable. Specifically, the distance between the first clamp assembly 2 and the support part 12 can be set according to the length of the assembly component 6 to be hoisted. Generally, the distance between the two is 50% to 90% of the length of the assembly component 6, preferably 80% or 85%.

[0083] like Figures 2 to 5 As shown, the telescopic component 3 is a component with telescopic function, such as a telescopic cylinder or a motor with a lead screw; multiple telescopic components 3 are arranged at intervals along the circumference of the assembly component 6, and the first end of each of the multiple telescopic components 3 is fixedly connected to the driving end of the first driving component by bolts, or can be hinged by a hinge shaft, and is slidably connected to the support part 12 along the first direction X.

[0084] Specifically, the number of telescopic components 3 can be 2 to 6, preferably, such as... Figure 4 and Figure 5 As shown, there are two telescopic components 3, which are evenly arranged around the circumference of the assembly part 6; or there can be four, arranged in a square array; as for the connection between the telescopic components 3 and the support part 12 and the second clamp assembly 4, a spherical hinge joint can be used.

[0085] like Figure 2 and Figure 3 As shown, the second clamp assembly 4 is hinged to the second ends of multiple telescopic components 3. The multiple telescopic components 3 can adjust the displacement of the second clamp assembly 4 along the second direction Y. The second clamp assembly 4 is used for radial fixed connection with the assembly component 6, that is, the included angle between the assembly component 6 and the central axis of the second clamp remains stable; wherein, as Figure 6As shown, the first direction X, the second direction Y, and the height direction of the support frame 1 intersect each other. Specifically, the included angle between any two of the first direction X, the second direction Y, and the height direction of the support frame 1 can be any angle. Preferably, the first direction X, the second direction Y, and the height direction of the support frame 1 are set perpendicular to each other, that is, the first direction X is perpendicular to the second direction Y, the first direction X is perpendicular to the height direction of the support frame 1, and the second direction Y is perpendicular to the height direction of the support frame 1.

[0086] More specifically, such as Figure 2 and Figure 3 As shown, the second clamp assembly 4 is located below the support part 12, and the first ends of the multiple telescopic components 3 are all hinged to the support part 12, that is, the second clamp assembly 4 can swing and hang below the support part 12 along the second direction Y.

[0087] More specifically, such as Figure 6 As shown, the support frame 1 is provided with two support rods 121. The two support rods 121 are arranged in parallel and extend along the first direction X. The two support rods 121 are support parts 12. Specifically, the support rods 121 are connected to the support frame 1 by welding or bolting.

[0088] like Figures 2 to 5 As shown, the telescopic assembly 3 includes a telescopic component 31 and a sliding groove 32. The sliding groove 32 is slidably connected to the support rod 121. The first end of the telescopic component 31 is hinged to the sliding groove 32, and the second end of the telescopic component 31 is hinged to the second clamp assembly 4. Specifically, the telescopic component 31 is a telescopic cylinder. The sliding groove 32 is a metal block with a sliding groove to slide with the support rod 121. More specifically, the support rod 121 is provided with multiple rollers to reduce sliding friction.

[0089] More specifically, such as Figures 2 to 5 As shown, the telescopic assembly 3 also includes a rotating sleeve 33, which is a metal sleeve. The rotating sleeve 33 is hinged to the second end of the telescopic member 31 via a rotating shaft. The hinge axes of the rotating sleeve 33 and the sliding groove body 32 to the telescopic member 31 are all parallel to the first direction X, thereby enabling the second clamp assembly 4 to sway along the second direction Y.

[0090] The rotating sleeve 33 is hinged to the second clamp assembly 4 via a rotating shaft. The hinge axis between the rotating sleeve 33 and the second clamp assembly 4 is parallel to the second direction Y, so that the second clamp assembly 4 can change its angle relative to the assembly part 6 during the reciprocating movement along the first direction X.

[0091] More specifically, the controller is electrically connected to the first drive component and multiple telescopic components 3. Specifically, the controller is a control module with data processing functions, such as a motherboard, a microcontroller, and a computing processing chip.

[0092] Specifically, the controller has a pre-set control program to send action commands to the first drive component and multiple telescopic components 3 to control the vertical posture of the assembly component 6.

[0093] More specifically, the controller is equipped with an adjustment model, the first clamp assembly 2 is equipped with a first displacement sensor, and the second clamp assembly 4 is equipped with a second displacement sensor. Before the first drive component and the multiple telescopic components 3 are activated, the first displacement sensor and the second displacement sensor can synchronously generate a first displacement signal and a second displacement signal. The controller can receive the first displacement signal and the second displacement signal and calculate the real-time relative displacement signal of the second displacement sensor relative to the first displacement sensor within a certain time period.

[0094] If at time N, the position signal of the first displacement sensor is (5,3) and the position signal of the second displacement sensor is (8,4), then the real-time relative displacement signal at time N is (3,1).

[0095] The controller acquires a periodic cyclic signal of the real-time relative displacement signal over a certain period of time. That is, the real-time relative displacement signal exhibits a periodic cycle over a certain period of time, which is due to the periodic cycle of wind and waves.

[0096] The controller obtains the periodic action signal with opposite displacement based on the periodic loop signal.

[0097] The controller decomposes the periodic action signal into a first periodic action signal executed by the first drive component and multiple second periodic action signals executed by multiple telescopic components 3.

[0098] The first drive component receives the first cycle action signal, and the multiple telescopic components 3 respectively receive multiple second cycle action signals, and then perform synchronous actions, which can effectively keep the assembly component 6 in a vertical posture.

[0099] More specifically, such as Figure 8 and Figure 9 As shown, the first clamp assembly 2 includes a first arc frame 21, a second arc frame 22, a third arc frame 23, and multiple first hydraulic cylinders 24. The first arc frame 21 is connected to the support frame 1 by bolts or welding. The first end of the second arc frame 22 and the first end of the third arc frame 23 are respectively hinged to the two ends of the second arc frame 22 by a pivot, and are driven to rotate by a second driving component. The second end of the second arc frame 22 and the second end of the third arc frame 23 can open and close to fix the assembly component 6. At least one first hydraulic cylinder 24 is provided on each of the first arc frame 21, the second arc frame 22, and the third arc frame 23 to radially limit the assembly component 6.

[0100] Specifically, such as Figure 9As shown, the first hydraulic cylinder 24 is a hydraulic oil cylinder used to adapt to the radial limit of assembly parts 6 of different diameters. The number of first hydraulic oil cylinders is 3 to 6, preferably 4.

[0101] like Figure 6 and Figure 7 As shown, the second clamp assembly 4 includes a fourth arc frame 41, a fifth arc frame 42, a sixth arc frame 43, and multiple second hydraulic cylinders 44. The fourth arc frame 41 is hinged to multiple telescopic components 3. The first ends of the fifth arc frame 42 and the sixth arc frame 43 are respectively hinged to the two ends of the fifth arc frame 42 and driven to rotate by the second driving component. The second ends of the fifth arc frame 42 and the sixth arc frame 43 can open and close to fix the assembly component 6. At least one second hydraulic cylinder 44 is provided on each of the fourth arc frame 41, the fifth arc frame 42, and the sixth arc frame 43 to radially limit the assembly component 6.

[0102] Specifically, such as Figure 7 As shown, the second hydraulic cylinder 44 is a constant pressure hydraulic cylinder, the number of the first hydraulic cylinders is 3 to 6, preferably 4, and the second driving component is a telescopic cylinder.

[0103] More specifically, such as Figure 1 and Figure 10 As shown, the wind power installation vessel lifting device also includes a lower lifting component 5, which is mounted on the support 12. The telescopic end of the lower lifting component 5 slides back and forth along the height direction of the support frame 1 for connection with the assembly component 6.

[0104] Specifically, such as Figure 10 As shown, the lower lifting component 5 includes a pulley 51, a rope 52, and a fixed pulley 53. The pulley 51 is driven by a reduction motor, the fixed pulley 53 is fixed on the support part 12, one end of the rope 52 is wound around the pulley 51, and the other end of the rope 52 is connected to the assembly part 6 through the fixed pulley 53.

[0105] According to an embodiment of this application, another aspect provides a ship, including a ship body 7 and a wind power installation ship lifting device as described in any of the above embodiments, wherein the support frame 1 is fixed to the ship body 7 by bolt connection and / or welding.

[0106] Specifically, the vessel is a ship used for hoisting equipment such as offshore wind turbines and oil platforms.

[0107] In this embodiment, since the ship includes a wind turbine installation vessel lifting device, it has the same technical effect as the wind turbine installation vessel lifting device, and will not be described in detail here.

[0108] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and all such modifications and variations fall within the scope defined by the appended claims.
