Description

Technical Field

[0001] The present application relates to the technical field of shipboard hoisting, and in particular to a wind power installation ship hoisting device and a ship. Background Art

[0002] In related technologies, as offshore wind power develops towards deep sea, the length of the pile legs of self-elevating wind turbine installation vessels cannot meet the needs of wind turbine installation in deep-water wind farms. Moreover, for wind farms with soft seabeds, the larger mud penetration depth of the pile legs of self-elevating wind turbine installation vessels increases the risk of construction. Therefore, a wind turbine lifting equipment suitable for deep-sea marine environments has been developed.

[0037] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.

[0038] It should be noted that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application. The terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. The terms "parallel", "perpendicular", and "equal" include the described situations and situations similar to the described situations, and the range of the similar situations is within the acceptable deviation range, where the acceptable deviation range is determined by those of ordinary skill in the art considering the measurements being discussed and the errors associated with the measurements of specific quantities (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallel and approximate parallel, and the acceptable deviation range of approximate parallel can be, for example, within 5° deviation; "perpendicular" includes absolute perpendicular and approximate perpendicular, and the acceptable deviation range of approximate perpendicular can also be, for example, within 5° deviation. "Equal" includes absolute equality and approximate equality, and the acceptable deviation range of approximate equality can be, for example, that the difference between the two equal ones is less than or equal to 5% of either one of them. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0039] In the related art, with the development of offshore wind power towards the deep sea, the leg length of the jack-up wind power installation vessel cannot meet the needs of installing wind turbines in deep-water wind farms. Moreover, for wind farms with soft seabeds, the relatively large penetration depth of the legs of the jack-up wind power installation vessel increases the construction risk. Therefore, a hoisting equipment for wind turbines applicable to the deep-sea marine environment has been developed. This equipment needs to overcome the ship motion caused by marine hydrological conditions, provide a relatively stable installation environment, and meet the requirements for docking during the on-site installation of wind turbines.

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

[0041] To solve the above problems, the present application provides a lifting device for a wind power installation ship and a ship, which can adjust and control the vertical posture of the assembled components and improve the assembly efficiency.

[0042] The following combines Figures 1 to 10 to describe the embodiments of the present application.

[0043] According to an embodiment of the present application, on the one hand, a lifting device for a wind power installation ship is provided, as Figure 1 shown, including a support frame 1, a first hoop assembly 2, a second hoop assembly 4, and a plurality of telescopic assemblies 3. The specific solutions are as follows.

[0044] As Figure 1 shown, the support frame 1 is a frame body welded by multiple steel pipes, or a frame body assembled by multiple steel frames; a lifting assembly 11 is provided on the upper part of the support frame 1 for lifting the assembled component 6. Specifically, the assembled component 6 can be a wind turbine unit or other components for offshore lifting; a support part 12 and a first driving component are provided on the lower part of the support frame 1. Specifically, the first driving component is a hydraulic cylinder with a telescopic function, or a motor connected with a lead screw, or a motor with a gear rack, etc.

[0045] As Figure 1 and Figure 8 shown, the first hoop assembly 2 is arranged on the support frame 1 by means of bolt screwing or electric welding, and is located above the support part 12 for limiting the upper part of the assembled component 6. The assembled component 6 can rotate relative to the first hoop assembly 2, that is, the angle between the assembled component 6 and the central axis of the first hoop remains stable; specifically, the distance between the first hoop assembly 2 and the support part 12 can be set according to the length of the assembled component 6 to be lifted. Generally, the distance between the two is 50% - 90% of the length of the assembled component 6, preferably 80% or 85%.

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

[0047] Specifically, the number of the telescopic assemblies 3 can be 2 - 6, preferably, as Figure 4 and Figure 5As shown, the number of telescopic components 3 is two, and the two telescopic components 3 are evenly arranged along the circumferential direction of the assembly component 6; it can also be four, arranged in a square array; as for the connection method between the telescopic component 3 and the support part 12 and the second hoop component 4, a spherical hinge joint can be used.

[0048] As Figure 2 and Figure 3 shown, the second hoop component 4 is hinged to the second ends of a plurality of telescopic components 3, and the plurality of telescopic components 3 can adjust the displacement of the second hoop component 4 along the second direction Y. The second hoop component 4 is used for radially fixedly connecting with the assembly component 6, that is, the angle between the central axis of the assembly component 6 and the second hoop is stable and unchanged; among them, as Figure 6 shown, the first direction X, the second direction Y and the height direction of the support frame 1 intersect pairwise. Specifically, the 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 perpendicular to each other pairwise, 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 the specific use process, as Figure 1 shown, taking the hoisting of a wind turbine by a hoisting device on a wind power installation ship as an example, the wind turbine is hoisted by the hoisting component 11 on the support frame 1, the upper part of the wind turbine is fixed by the first hoop component 2, the lower part of the wind turbine is fixed by the second hoop component 4, and the ship's own DP system is used to control the plane coordinates of the ship to ensure the stability of the ship. However, due to the influence of sea waves and winds, the ship will shake, resulting in the inclination of the wind turbine.

[0050] The first driving component is used to drive the first end of the telescopic component to reciprocally move along the first direction X on the support part 12, so that the second hoop component 4 reciprocally moves along the first direction X, and in combination with the telescopic cooperation of the telescopic component 3 (that is, some telescopic members 31 contract, some telescopic members 31 extend, or contract and extend simultaneously), the second hoop component 4 is moved along the second direction Y, so as to keep the wind turbine in a vertical posture and facilitate assembly.

[0051] In this embodiment, as Figures 1 to 5 shown, the second hoop component 4 reciprocally slides along the first direction X with the support part 12 through a plurality of telescopic components 3, and through the telescopic cooperation of the plurality of telescopic components 3, the displacement of the second hoop in the second direction Y is adjusted, so as to offset the inclination of the assembly component 6 caused by the shaking of the sea waves, so as to ensure the vertical posture of the assembly component 6 and improve the assembly efficiency.

[0052] In one embodiment, as Figure 2 andFigure 3 As shown, the second hoop assembly 4 is located below the support portion 12. The first ends of the plurality of telescopic assemblies 3 are all hinged to the support portion 12, that is, the second hoop assembly 4 can be hung and connected below the support portion 12 and can swing along the second direction Y.

[0053] During the specific use process, the included angle between the second hoop assembly 4 and the assembly component 6 is stable and unchanged. When the assembly component 6 is tilted, by telescoping some of the telescopic members 31, some of the telescopic members 31 extending, or telescoping simultaneously, it is possible to move the portion of the assembly component 6 located at the second hoop assembly 4 in the opposite direction of the swing. Since the second hoop assembly 4 is located below the support portion 12, the second hoop assembly 4 is in a downward pull state on the support portion 12, which facilitates the movement of the second hoop assembly 4 and is convenient for adjusting the vertical posture of the assembly component 6.

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

[0055] During the specific use process, since the second hoop assembly 4 is located above the support portion 12 and the second hoop assembly 4 is supported above the support portion 12 by the telescopic assemblies 3, although by telescoping some of the telescopic members 31, some of the telescopic members 31 extending, or telescoping simultaneously, it is possible to move the portion of the assembly component 6 located at the second hoop assembly 4 in the opposite direction of the swing to offset the tilt caused by the swing of the hull. However, the second hoop assembly 4 is in a downward pressure state on the support portion 12, with poor structural stability, which will affect the movement accuracy of the second hoop assembly 4 and is not convenient for adjusting the vertical posture of the assembly component 6.

[0056] In one embodiment, as Figure 6 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 the support portion 12; specifically, the support rods 121 are connected to the support frame 1 by welding or by bolt screwing.

[0057] As Figures 2 to 5 shown, the telescopic assembly 3 includes a telescopic member 31 and a chute body 32. The chute body 32 is slidably connected to the support rod 121. The first end of the telescopic member 31 is hinged to the chute body 32, and the second end of the telescopic member 31 is hinged to the second hoop assembly 4. Specifically, the telescopic member 31 is a telescopic cylinder; the chute body 32 is a metal block body, and a chute is provided on the chute body 32 for sliding connection with the support rod 121. More specifically, a plurality of rollers are provided on the support rod 121 to reduce the sliding friction force.

[0058] During specific use, the chute body 32 is drivingly connected to the first driving component, and the telescopic end of the first driving component is used to drive the chute body 32 to reciprocate relative to the support rod 121.

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

[0060] In one embodiment, as Figures 2 to 5 shown, the telescopic assembly 3 further includes a rotating sleeve 33. The rotating sleeve 33 is a sleeve made of metal. The rotating sleeve 33 is hinged to the second end of the telescopic member 31 through a rotating shaft. The hinge axes of the rotating sleeve 33 and the chute body 32 with the telescopic member 31 are both parallel to the first direction X, so that the second hoop assembly 4 can swing along the second direction Y.

[0061] The rotating sleeve 33 is hinged to the second hoop assembly 4 through a rotating shaft. The hinge axis of the rotating sleeve 33 and the second hoop assembly 4 is parallel to the second direction Y. When the second hoop assembly 4 reciprocates along the first direction X, it can change the angle relative to the assembly component 6.

[0062] In this embodiment, since the hinge axes of the rotating sleeve 33 and the chute body 32 with the telescopic member 31 are both parallel to the first direction X, and the hinge axis of the rotating sleeve 33 and the second hoop assembly 4 is parallel to the second direction Y, it is convenient to perform a combined movement 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 ship hoisting device further includes a controller, which is electrically connected to the first driving component and multiple telescopic assemblies 3. Specifically, the controller is a control module with data processing functions such as a main board, a single-chip microcomputer, and a calculation and processing chip.

[0064] Specifically, a control program is preset in the controller to send action commands to the first driving component and multiple telescopic assemblies 3 to control the vertical posture of the assembly component 6.

[0065] In an embodiment not shown, an adjustment model is set in the controller. A first displacement sensor is provided on the first hoop assembly 2, and a second displacement sensor is provided on the second hoop assembly 4. Before the first driving component and multiple telescopic assemblies 3 act, 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] At the Nth moment, if 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 the Nth moment is (3, 1).

[0067] The controller obtains the periodic cyclic signal of the real-time relative displacement signal within a certain period of time, that is, within a certain period of time, the real-time relative displacement signal is cyclical, because the wind and waves are cyclical.

[0068] The controller obtains the periodic action signal of the opposite displacement according to the periodic cyclic signal.

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

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

[0071] In one embodiment, as Figure 8 and Figure 9 shown, the first hoop component 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 means of bolt screwing or welding. The first ends of the second arc frame 22 and the third arc frame 23 are respectively hinged to the two ends of the second arc frame 22 through a rotating shaft, and are respectively driven to rotate by a second driving component. The second ends of the second arc frame 22 and the third arc frame 23 can be opened and closed 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 perform radial limit on the assembly component 6.

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

[0073] As Figure 6 and Figure 7As shown in the figure, the second hoop assembly 4 includes a fourth arc frame 41, a fifth arc frame 42, a sixth arc frame 43, and a plurality of second hydraulic cylinders 44. The fourth arc frame 41 is hinged to a plurality of telescopic assemblies 3. The first ends of the fifth arc frame 42 and the sixth arc frame 43 are respectively hinged to both ends of the fifth arc frame 42 and are respectively driven to rotate by second driving components. The second ends of the fifth arc frame 42 and the sixth arc frame 43 can be opened and closed 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 perform radial limiting on the assembly component 6.

[0074] Specifically, as Figure 7 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. The second driving component is a telescopic cylinder.

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

[0076] In one embodiment, as Figure 1 and Figure 10 shown, the wind power installation ship hoisting device further includes a lower hoisting component 5. The lower hoisting component 5 is arranged on the support portion 12. The telescopic end of the lower hoisting component 5 reciprocally slides along the height direction of the support frame 1 and is used to connect with the assembly component 6.

[0077] Specifically, as Figure 10 shown, the lower hoisting component 5 includes a runner 51, a rope 52, and a fixed pulley 53. The runner 51 is driven by a reduction motor. The fixed pulley 53 is fixed on the support portion 12. One end of the rope 52 is wound around the runner 51, and the other end of the rope 52 is connected with the assembly component 6 through the fixed pulley 53.

[0078] In this embodiment, by providing the lower hoisting component 5 and combining with the hoisting assembly 11, the upper and lower parts of the assembly component 6 are hoisted synchronously, which can improve the hoisting stability and prevent problems such as deformation and damage of the assembly component 6.

[0079] Next, a wind power installation ship hoisting device will be comprehensively described with an example.

[0080] This embodiment provides a wind power installation ship hoisting device, as Figure 1 shown, including a support frame 1, a first hoop assembly 2, a second hoop assembly 4, a controller, and a plurality of telescopic assemblies 3. The specific scheme is as follows.

[0081] AsFigure 1 As shown, the support frame 1 is a frame body welded by multiple steel pipes, or a frame body assembled by multiple steel frames; a hoisting assembly 11 is arranged on the upper part of the support frame 1 for hoisting the assembled component 6. Specifically, the assembled component 6 can be a fan unit or other components used for offshore hoisting; a support part 12 and a first driving component are arranged on the lower part of the support frame 1. Specifically, the first driving component is a hydraulic cylinder with a telescopic function, or an electric motor connected with a lead screw, or an electric motor with a gear rack, etc.

[0082] As Figure 1 and Figure 8 As shown, the first hoop assembly 2 is arranged on the support frame 1 by means of bolt screwing or electric welding, and is located above the support part 12 for limiting the upper part of the assembled component 6. The assembled component 6 can rotate relative to the first hoop assembly 2, that is, the included angle between the assembled component 6 and the central axis of the first hoop remains stable; specifically, the distance between the first hoop assembly 2 and the support part 12 can be set according to the length of the assembled component 6 to be hoisted. Generally, the distance between the two is 50% - 90% of the length of the assembled component 6, preferably 80% or 85%.

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

[0084] Specifically, the number of the telescopic assemblies 3 can be 2 - 6, preferably, as Figure 4 and Figure 5 As shown, the number of the telescopic assemblies 3 is two, and the two telescopic assemblies 3 are evenly arranged along the circumferential direction of the assembled component 6; it can also be 4, arranged in a square array; as for the connection mode between the telescopic assembly 3 and the support part 12 and the second hoop assembly 4, a spherical hinge joint can be adopted.

[0085] As Figure 2 and Figure 3 As shown, the second hoop assembly 4 is hinged to the second ends of the multiple telescopic assemblies 3. The multiple telescopic assemblies 3 can adjust the displacement of the second hoop assembly 4 along the second direction Y. The second hoop assembly 4 is used for radially fixedly connecting with the assembled component 6, that is, the included angle between the assembled component 6 and the central axis of the second hoop remains stable; among them, as Figure 6As shown, the first direction X, the second direction Y, and the height direction of the support frame 1 intersect pairwise. 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 perpendicular to each other pairwise, 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] Further specifically, as Figure 2 and Figure 3 shown, the second hoop assembly 4 is located below the support portion 12, and the first ends of the plurality of telescopic assemblies 3 are all hinged to the support portion 12, that is, the second hoop assembly 4 can be swingingly hung below the support portion 12 along the second direction Y.

[0087] Further specifically, as Figure 6 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 the support portion 12. Specifically, the support rods 121 are connected to the support frame 1 by welding or bolt screwing.

[0088] As Figures 2 to 5 shown, the telescopic assembly 3 includes a telescopic member 31 and a chute body 32. The chute body 32 is slidably connected to the support rod 121. The first end of the telescopic member 31 is hinged to the chute body 32, and the second end of the telescopic member 31 is hinged to the second hoop assembly 4. Specifically, the telescopic member 31 is a telescopic cylinder. The chute body 32 is a metal block body, and a chute is provided on the chute body 32 for sliding connection with the support rod 121. More specifically, a plurality of rollers are provided on the support rod 121 to reduce the sliding friction force.

[0089] Further specifically, as Figures 2 to 5 shown, the telescopic assembly 3 further includes a rotating sleeve 33. The rotating sleeve 33 is a sleeve made of metal. The rotating sleeve 33 is hinged to the second end of the telescopic member 31 by a rotating shaft. The hinged axes of the rotating sleeve 33 and the chute body 32 with the telescopic member 31 are both parallel to the first direction X, so that the second hoop assembly 4 can swing along the second direction Y.

[0090] The rotating sleeve 33 is hinged to the second hoop assembly 4 by a rotating shaft. The hinged axis of the rotating sleeve 33 and the second hoop assembly 4 is parallel to the second direction Y, so that when the second hoop assembly 4 moves reciprocally along the first direction X, it can change the angle relative to the assembly part 6.

[0091] Further specifically, the controller is electrically connected to the first driving component and the plurality of telescopic assemblies 3. Specifically, the controller is a control module with data processing functions such as a main board, a single-chip microcomputer, and a computing and processing chip.

[0092] Specifically, a control program is preset in the controller to send action commands to the first driving component and the plurality of telescopic components 3 to control the vertical attitude of the assembly component 6.

[0093] More specifically, an adjustment model is set in the controller. A first displacement sensor is provided on the first hoop component 2, and a second displacement sensor is provided on the second hoop component 4. Before the first driving component and the plurality of telescopic components 3 act, 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] For example, at the Nth moment, 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 the Nth moment is (3, 1).

[0095] The controller obtains the periodic cyclic signal of the real-time relative displacement signal within a certain time, that is, within a certain time, the real-time relative displacement signal is cycled periodically because the wind and waves are cycled periodically.

[0096] The controller obtains the periodic action signal of the opposite displacement according to the periodic cyclic signal.

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

[0098] The first driving component receives the first periodic action signal, and the plurality of telescopic components 3 respectively receive the plurality of second periodic action signals and then perform synchronous actions, which can effectively keep the assembly component 6 in a vertical attitude.

[0099] More specifically, as Figure 8 and Figure 9 shown, the first hoop component 2 includes a first arc frame 21, a second arc frame 22, a third arc frame 23 and a plurality of first hydraulic cylinders 24. The first arc frame 21 is connected to the support frame 1 by means of bolt screwing or welding. The first ends of the second arc frame 22 and the third arc frame 23 are respectively hinged to both ends of the second arc frame 22 through a rotating shaft and are respectively driven to rotate by a second driving component. The second ends of the second arc frame 22 and the third arc frame 23 can be opened and closed 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 perform radial limit on the assembly component 6.

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

[0101] As Figure 6 and Figure 7 shown, the second hoop assembly 4 includes a fourth arc frame 41, a fifth arc frame 42, a sixth arc frame 43 and a plurality of second hydraulic cylinders 44. The fourth arc frame 41 is hinged to a plurality of telescopic assemblies 3. The first ends of the fifth arc frame 42 and the sixth arc frame 43 are respectively hinged to both ends of the fifth arc frame 42 and are respectively driven to rotate by a second driving component. The second ends of the fifth arc frame 42 and the sixth arc frame 43 can be opened and closed to fix the assembly component 6. At least one second hydraulic cylinder 44 is arranged on each of the fourth arc frame 41, the fifth arc frame 42 and the sixth arc frame 43 to perform radial limit on the assembly component 6.

[0102] Specifically, as Figure 7 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. The second driving component is a telescopic oil cylinder.

[0103] Further specifically, as Figure 1 and Figure 10 shown, the wind power installation ship hoisting device further includes a lower hoisting component 5. The lower hoisting component 5 is arranged on the support portion 12. The telescopic end of the lower hoisting component 5 reciprocally slides along the height direction of the support frame 1 and is used to connect with the assembly component 6.

[0104] Specifically, as Figure 10 shown, the lower hoisting component 5 includes a runner 51, a rope 52 and a fixed pulley 53. The runner 51 is driven by a reduction motor. The fixed pulley 53 is fixed on the support portion 12. One end of the rope 52 is wound around the runner 51, and the other end of the rope 52 is connected with the assembly component 6 through the fixed pulley 53.

[0105] According to an embodiment of the present application, on the other hand, a ship is provided, which includes a ship body 7 and the wind power installation ship hoisting device in any one of the above embodiments. The support frame 1 is fixed on the ship body 7 by means of bolt connection and / or welding.

[0106] Specifically, the ship is a hull for hoisting equipment such as an offshore wind turbine generator set, an oil platform, etc.

[0107] In this embodiment, since the ship includes the wind power installation ship hoisting device and has the same technical effects as the wind power installation ship hoisting device, no further description will be given here.

[0108] Although embodiments of the present application are 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 the present application, and such modifications and variations fall within the scope defined by the appended claims.
