Description

Technical Field

[0001] The present invention relates to the technical field of fan hoisting, and particularly to an offshore fan hoisting device. Background Art

[0002] With the popularization of wind power generation, the deployment has begun to extend to the sea. When installing a wind turbine at sea, it is necessary to first drive the support column into the seabed and then install the fan with blades on the support column. Since the fan with blades is heavy, hoisting equipment is required to lift the fan.

[0003] During use, the existing hoisting equipment mainly lifts the fan through the cooperation of a hanging bracket and a steel cable. After the fan is lifted, due to strong sea winds and the lack of limit for the fan, the phenomenon of fan swing will occur. When docking with the support column, it is necessary to repeatedly adjust the position of the fan to carry out the docking, which takes a long time and results in low docking efficiency. Summary of the Invention

Detailed implementation manners

[0025] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention in conjunction with the accompanying drawings of the specification.

[0026] In the following description, many specific details are set forth to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0027] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present invention. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or selectively exclusive embodiment with other embodiments.

[0028] Example 1

[0029] Referring to Figures 1 to 6 , which is the first embodiment of the present invention. This embodiment provides an offshore wind turbine hoisting device that can prevent the hoisted wind turbine from shaking. It includes a support component 100, which includes a crane body 101, a steel cable 102 arranged on the crane body 101, a lifting rope 103 arranged at the end of the steel cable 102, and an inclined plate 104 arranged on the crane body 101; a balance component 200, which includes a lifting assembly 201 arranged on the inclined plate 104, a telescopic assembly 202 arranged on the lifting assembly 201, a transmission assembly 203 arranged on the telescopic assembly 202, a clamping assembly 204 arranged on the transmission assembly 203, and an adjustment assembly 205 arranged on the clamping assembly 204; a length adjustment component 300, which includes a guiding assembly 301 arranged on the inclined plate 104, and a guiding component 302 arranged on the lifting assembly 201; a reinforcement component 400, which includes a gas pumping assembly 401 arranged on the guiding assembly 301, and a stabilizing assembly 402 arranged on the lifting assembly 201.

[0030] Specifically, the crane body 101 here can be arranged on a bed or on a vehicle on the shore. The method is not unique as long as it can hoist the wind turbine, and it can be selected according to the actual situation. The steel cable 102 on the crane body 101 is rigid enough and will not cause the phenomenon of the steel cable 102 falling off when hoisting the wind turbine. The process of the crane hoisting the wind turbine here is prior art and will not be elaborated herein.

[0031] Furthermore, the lifting assembly 201 includes an electric slide rail 201a arranged on the inclined plate 104. A slider 201b is slidably connected to the electric slide rail 201a. Connecting bars 201c are fixedly connected to both the upper and lower ends of the slider 201b. A first ring 201d is fixedly connected to the connecting bar 201c; the telescopic assembly 202 includes a hydraulic cylinder 202a arranged inside the first ring 201d. A sliding sleeve 202b is slidably connected to the hydraulic cylinder 202a. A magnetic ring 202c is fixedly connected to the sliding sleeve 202b. A magnetic block 202d that cooperates with the magnetic ring 202c is fixedly connected to the telescopic end of the hydraulic cylinder 202a. Stop rings 202e are fixedly connected to both the hydraulic cylinder 202a and the sliding sleeve 202b; the transmission assembly 203 includes a cylinder 203a fixedly connected to the sliding sleeve 202b. A through port 203b is provided inside the cylinder 203a. An expansion cavity 203c is provided on the side wall of the through port 203b. A moving disk 203d is slidably connected to the expansion cavity 203c. The moving disk 203d is elastically connected to the inner wall of the expansion cavity 203c by a first spring 203e.

[0032] Among them, the slider 201b here is T-shaped and will not be separated from the electric slide rail 201a during movement. The diameter of the first ring 201d is larger than the diameter of the hydraulic cylinder 202a. The suction force between the magnetic ring 202c and the magnetic block 202d is greater than the frictional resistance during the movement of the sliding sleeve 202b. Therefore, when the telescopic end of the hydraulic cylinder 202a moves, it can drive the sliding sleeve 202b to move. The setting of the stop ring 202e can block the sliding sleeve 202b. The diameter of the through port 203b here is larger than the diameter of the telescopic end of the hydraulic cylinder 202a, so that the telescopic end of the hydraulic cylinder 202a will not be blocked when moving.

[0033] Preferably, the clamping assembly 204 includes three guiding ports 204a provided on the cylinder 203a. A moving block 204b is slidably connected in the guiding port 204a. An L-shaped block 204c is provided on the moving block 204b. A support groove 204d is provided on the side wall of the guiding port 204a. A rotating shaft 204e is fixedly connected to the support groove 204d. A rotating block 204f is rotatably connected to the rotating shaft 204e. A connecting bar 204g is fixedly connected to the side wall of the moving block 204b. A bearing block 204h is fixedly connected to the connecting bar 204g. A first receiving groove 204i is provided on the bearing block 204h. An arc-shaped head 204j matched with the first receiving groove 204i is provided on the rotating block 204f. A support column 204k is fixedly connected to the moving disk 203d. A second receiving groove 204l matched with the arc-shaped head 204j is provided on the support column 204k; the adjusting assembly 205 includes a guiding port 205a penetrating through the moving block 204b. A guiding rod 205b is slidably connected in the guiding port 205a. The guiding rod 205b is fixedly connected to the L-shaped block 204c. A threaded port 205c extending to the L-shaped block 204c is provided on the moving block 204b. A screw rod 205d is threadedly connected in the threaded port 205c. A turntable 205e is fixedly connected to the outer end of the screw rod 205d.

[0034] It should be noted that the three guiding ports 204a here are misaligned with the blades of the fan (generally, a fan has three blades), so that the phenomenon that the L-shaped block 204c abuts against the fan blades will not occur. At the same time, when lifting here, since the inclination angle of the crane body 101 is certain, when the fan is lifted, it can be ensured that the guiding ports 204a are misaligned with the fan blades. The setting of the arc-shaped head 204j avoids the phenomenon that the rotating block 204f is stuck with the first receiving groove 204i and the second receiving groove 204l. The cooperation between the screw rod 205d and the threaded rod can adjust the distance between the L-shaped block 204c and the moving block 204b, and can be applicable to fan blades of different thicknesses.

[0035] When in use, the lifting rope 103 is wound around the fan, and then the crane body 101 lifts the fan through the steel cable 102, and then the electric slide rail 201a is started, and the position of the slider 201b is adjusted, thereby adjusting the height of the transfer bar 201c, and then adjusting the height of the hydraulic cylinder 202a, so that the L-shaped block 204c is misaligned with the blades of the fan, and then the telescopic end of the hydraulic cylinder 202a is extended, so that the magnetic block 202d moves toward the fan, and then the magnetic ring 202c moves toward the fan, and then the sliding sleeve 202b moves toward the fan. When the sliding sleeve 202b moves toward the fan, it can drive the cylinder 203 a moves toward the fan. At this time, the L-shaped block 204c is on the outside of the fan blade. When the stop ring 202e on the sliding sleeve 202b and the stop ring 202e on the hydraulic cylinder 202a are against each other, the side wall of the fan blade is between the moving block 204b and the L-shaped block 204c. The hydraulic cylinder 202a continues to extend, causing the magnetic block 202d to separate from the magnetic ring 202c. Then the hydraulic cylinder 202a extends into the through-hole 203b. As the hydraulic cylinder 202a continues to extend, it can push the moving plate 203d to move toward the fan. The first spring 203e extends. When the moving plate 203d moves, The support column 204k can be driven to move, so that the second receiving groove 204l cooperates with the rotating block 204f, and can drive the rotating block 204f to rotate counterclockwise (when viewed from the front of the rotating block 204f, the same below). When the rotating block 204f rotates counterclockwise, the arc-shaped head 204j at the upper end of the rotating block 204f cooperates with the first receiving groove 204i, and can drive the bearing block 204h to move downward, thereby driving the connecting bar 204g to move downward, so that the moving block 204b moves downward, and the guide port 204a guides the moving block 204b. When the moving block 204b moves downward, it can drive the L-shaped Block 204c moves downward, so that the fan blades are stuck between the moving block 204b and the L-shaped block 204c, and the fan blades are limited, thereby realizing the limitation of the fan and avoiding the fan swinging after being lifted. When it is necessary to use fan blades of different widths, it is only necessary to rotate the turntable 205e to rotate the screw 205d, thereby moving the L-shaped block 204c and changing the distance between the moving block 204b and the L-shaped block 204c, so as to use fan blades of different widths. When the L-shaped block 204c moves, the guide rod 205b slides in the guide port 205a to guide the L-shaped block 204c.

[0036] In summary, by setting up the balancing component 200, after the fan is lifted, the fan blades can be clamped between the movable block 204b and the L-shaped block 204c through transmission to limit the fan blades, thereby preventing the fan blades from swinging due to wind after lifting, and avoiding displacement and installation.

[0037] Example 2

[0038] Reference Figures 2 to 7, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides an elongation component 300 for the offshore wind turbine hoisting equipment, which solves the problem of how to avoid the inclination of the hoisted wind turbine caused by the length problem of the hydraulic cylinder 202a during lifting. It includes a guiding component 301, which includes a fixing plate 301a fixedly connected to the inclined plate 104. An arc-shaped opening 301b is provided on the fixing plate 301a. A guiding column 301c is slidably connected in the arc-shaped opening 301b. A stop disk 301d is fixedly connected to the guiding column 301c. A second ring 301e is fixedly connected to the guiding column 301c. The non-extending end of the hydraulic cylinder 202a is fixedly connected to a third ring 301f. The second ring 301e and the third ring 301f are fixedly connected by a connecting column 301g; the guiding component 302 includes an installation groove 302a provided on the first ring 201d. A support shaft 302b is rotatably connected in the installation groove 302a. A guiding wheel 302c is fixedly connected to the support shaft 302b.

[0039] Specifically, the fixing plate 301a is arranged between the hydraulic cylinder 202a and the inclined plate 104. The arc-shaped opening 301b on the fixing plate 301a gradually moves away from the hydraulic cylinder 202a as the height increases. Two stop disks 301d are provided, and the fixing plate 301a is located between the two stop disks 301d, so as to prevent the guiding column 301c from detaching from the fixing plate 301a. The setting of the guiding wheel 302c reduces the friction force between the first ring 201d and the hydraulic cylinder 202a. There is a gap between the second ring 301e and the third ring 301f, which facilitates the connection of the pipeline on the side wall of the hydraulic cylinder 202a.

[0040] During use, when the wind turbine needs to move up and down during hoisting, the electric slide rail 201a moves, driving the first ring 201d to move, so that the hydraulic cylinder 202a moves to achieve balance in the vertical direction, and the fan blades are always clamped between the L-shaped block 204c and the moving block 204b. While the hydraulic cylinder 202a moves, it drives the second ring 301e to move, thereby driving the connecting column 301g to move and driving the third ring 301f to move. When moving upward, the third ring 301f moves upward. At this time, the guiding column 301c slides in the arc-shaped opening 301b. Since the arc-shaped opening 301b on the fixing plate 301a gradually moves away from the hydraulic cylinder 202a as the height increases, the hydraulic cylinder 202a moves away from the wind turbine (due to the inclination of the frame of the crane body 101, the closer the frame of the crane body 101 is to the wind turbine as it goes up, so the left and right position adjustment of the hydraulic cylinder 202a is required), thus avoiding the swing of the wind turbine pushed by the hydraulic cylinder 202a. When the hydraulic cylinder 202a moves, the setting of the guiding wheel 302c reduces the friction force between the first ring 201d and the hydraulic cylinder 202a.

[0041] In summary, by providing the length-adjusting component 300, when the fan is lifted or lowered, the electric slide rail 201a drives the slider 201b to move, causing the hydraulic cylinder 202a to move. This movement coordinates with the lifting and lowering of the fan. Moreover, when the hydraulic cylinder 202a is lifted or lowered, it can drive the hydraulic cylinder 202a to move left and right, preventing the L-shaped block 204c at the right end of the hydraulic cylinder 202a from pushing the fan outwards and ensuring the stability of the lifted fan.

[0042] Embodiment 3

[0043] Referring to Figures 2 to 7 , this is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a reinforcement component 400 for the offshore wind turbine hoisting device, which solves the problem of how to prevent the hydraulic cylinder 202a from sliding when hoisting. It includes a gas pumping assembly 401, which includes an arc-shaped airbag 401a disposed on the arc-shaped opening 301b, and a gas pumping pipe 401b is connected to the arc-shaped airbag 401a in communication; a stabilizing assembly 402 includes an annular cavity 402a disposed on the first ring 201d, a strip-shaped cavity 402b is provided on the annular cavity 402a, an arc-shaped groove 402c is provided on the first ring 201d, a sealing plug 402d is slidably connected in the strip-shaped cavity 402b, a push plate 402e is fixedly connected to the sealing plug 402d, the push plate 402e penetrates the annular cavity and is slidably connected to the annular cavity, a friction block 402f is fixedly connected to the push plate 402e, the gas pumping pipe 401b is communicated with the annular cavity 402a, and the sealing plug 402d is elastically connected to the inner wall of the annular cavity 402a through a second spring 402g.

[0044] Specifically, the arc-shaped airbag 401a is provided with creases and can be folded along the creases without significant deviation in the front-rear direction. With the setting of the annular cavity 402a, when pumping gas, it can drive multiple sealing plugs 402d to slide simultaneously. The setting of the friction block 402f makes the friction block 402f abut against the side wall of the hydraulic cylinder 202a when the hydraulic cylinder 202a moves to a high position, preventing the hydraulic cylinder 202a from sliding between the first ring 201d when hoisting. When the friction block 402f abuts against the side wall of the hydraulic cylinder 202a, it only increases the friction force and does not affect the movement of the hydraulic cylinder 202a.

[0045] During use, when the guide post 301c moves, it can squeeze the arc-shaped airbag 401a, pump the gas in the arc-shaped airbag 401a into the arc-shaped cavity through the gas pumping pipe 401b, push the sealing plug 402d to move, and thus the push plate 402e moves, causing the friction block 402f to move towards the hydraulic cylinder 202a. The friction block 402f provides friction force to prevent the relative sliding between the hydraulic cylinder 202a and the first ring 201d when not lifting or lowering, further ensuring the stability of the hoisted fan.

[0046] In summary, by providing the reinforcement member 400, the friction force between the first ring 201d and the side wall of the hydraulic cylinder 202a can be increased, preventing the hydraulic cylinder 202a from moving slightly when not lifting or lowering, further ensuring the stability of the hydraulic cylinder 202a and the stability of the fan after being lifted.
