Description

Technical Field

[0001] The present invention relates to the technical field of offshore engineering construction, and mainly relates to a large distribution hanger for adjusting the posture, decoupling and damping vibration of an offshore photovoltaic Background Art

[0002] The modular assembly, transportation and hoisting of offshore engineering are difficult. Large distribution hangers are usually used to hoist large modular components. During the hoisting process, it is necessary to realize the stable flipping and posture adjustment of the module at a certain wind speed, and realize the automatic decoupling of the high-altitude hook.

[0003] The Chinese patent application with the publication number of CN119660530A discloses a lifting tool for a large offshore photovoltaic bracket, including a hanger, two long and short suspension rods, four boom arms, four boom rotation mechanisms and four hoops. The hanger is a rectangular frame composed of two long and short main rods; four upper ear plates are respectively fixed at the four corners of the top surface of the hanger; the two long and short suspension rods are respectively fixed at the bottom ends of the two long main rods of the hanger; the boom arm includes a sleeve, a horizontal rod vertically connected to the bottom of the sleeve, a diagonal brace rod connected between the top surface of the outer end of the horizontal rod and the outer surface of the top of the sleeve, and a lower ear plate installed on the bottom surface of the outer end of the horizontal rod; the four boom arms are respectively sleeved on the lower parts of the two long and short suspension rods through the sleeves; the four boom rotation mechanisms are respectively installed at the bottoms of the four boom arms; the four hoops are respectively suspended on the lower ear plates of the four boom arms through hanging rings, which can keep the inclined state of the photovoltaic bracket and ensure the accurate hoisting of the photovoltaic bracket.

[0004] However, the existing hanger can only realize angle control by methods such as lifting and hoisting, and the control accuracy of the inclination angle is low. At the same time, the sling is prone to bumping against large modular components when descending, and it is difficult to protect the finished products. Under the action of wind load, there will also be a large shaking amplitude, resulting in low reliability of the hanger.

[0005] Therefore, how to effectively improve the stability of the inclination angle adjustment of the hanger, facilitate the decoupling and descending of large modular components, and improve the overall reliability of the hanger has become an urgent problem to be solved in this field. Summary of the Invention

[0006] Aiming at the defects of the prior art, the purpose of the present invention is to provide a stable and reliable large distribution hanger for adjusting the posture, decoupling and damping vibration of an offshore photovoltaic and a hoisting method.

[0007] To achieve the above purpose, the large distribution hanger for adjusting the posture, decoupling and damping vibration of an offshore photovoltaic provided by the present invention includes a frame body

[0008] Integrated lifting beams are respectively provided at the four corners of the frame body. Adjusting modules and follow-up wire winding modules are respectively provided at both ends of the integrated lifting beam. A sling is provided at the end of the adjusting module. The adjusting module is configured to adjust the motion state of the sling. A hook release device is provided on the sling. The hook release wire of the hook release device is wound and unwound through the follow-up wire winding module and is elastically connected and cooperated with the follow-up wire winding module. The hook release device is configured to fix and release the sling.

[0009] A modular vibration damping unit and a system controller are further provided on the frame body. The modular vibration damping unit is configured to dissipate energy by vibration. The system controller is configured to control the working states of the adjusting module, the follow-up wire winding module, and the hook release device.

[0010] Furthermore, a photovoltaic energy storage module is provided on the frame body. The photovoltaic energy storage module is configured to provide a driving power source for the adjusting module, the follow-up wire winding module, the hook release device, and the system controller.

[0011] Furthermore, the adjusting module is hung under both ends of the integrated lifting beam and includes an adjusting electric hoist.

[0012] Furthermore, the follow-up wire winding modules are horizontally distributed at both ends of the integrated lifting beam and are arranged above the adjusting module. The follow-up wire winding module includes a wire winding module shaft. A reel and a spring winding are provided on the wire winding module shaft. One end of the wire winding module shaft is provided with a wire winding connection for cooperating with the hook release wire.

[0013] Furthermore, the hook release device includes a hook release device housing, a fixing component, and a gear drive component and a movable locking tongue provided in the hook release device housing. One end of the movable locking tongue is cooperated with the gear drive component, and the other end extends out of the hook release device housing and is in dynamic contact and cooperation with the fixing component.

[0014] Furthermore, one end of the hook release wire of the hook release device is connected to the gear drive component, and the other end is coiled on the reel and passes through the wire winding module shaft and the wire winding connection box to connect the photovoltaic energy storage module.

[0015] Furthermore, the sling includes a first sling and a second sling. Both ends of the first sling are respectively connected to the adjusting module and the fixing component. The first end of the second sling is connected to the adjusting module, and the second end is cooperated with the movable locking tongue.

[0016] Further, the modular damping unit is arranged at the bottom end of the frame body and includes a damping unit housing. Inside the damping unit housing, there is a damping unit mass block, and a damping unit spring is arranged between the damping unit mass block and the inner side surface of the damping unit housing. The inner top surface and inner bottom surface of the damping unit housing are respectively provided with damping unit chutes for cooperating with the damping unit mass block.

[0017] Further, a short-direction cavity is formed between the damping unit mass block and the damping unit housing, and the short-direction cavity is filled with damping liquid.

[0018] In order to achieve the above object, the hoisting method of the large-scale distribution hanger for adjusting the posture and decoupling and damping of offshore photovoltaic power generation provided by the present invention is based on the large-scale distribution hanger for adjusting the posture and decoupling and damping of offshore photovoltaic power generation, and the hoisting method includes:

Through the cooperation of the follow-up wire winding module and the decoupling device, the sling can be released at any angle, realizing the rapid separation of the sling and the object to be hoisted. At the same time, the follow-up wire winding module can wind and unwind the decoupling wire of the decoupling device and elastically connect and cooperate with the decoupling wire to keep the decoupling wire in a taut state, preventing the decoupling wire from being wound around the sling, thereby improving the reliability of the hanger.

[0023] Further, the high-altitude damping of the frame body is synchronously realized through the modular damping unit on the frame body, reducing the influence of wind load on the hanger and improving the stability of the hanger. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below with reference to specific illustrations.

[0041] See Figure 1 and Figure 2 , which shows an example of a large-scale distribution hanger for adjusting the posture, decoupling and damping vibration of offshore photovoltaic systems provided by the present invention.

[0042] As can be seen from the figure, the large-scale distribution hanger for adjusting the posture, decoupling and damping vibration of offshore photovoltaic systems in this example mainly includes a frame body 1, an integrated balance beam 2, a posture adjustment module 3, a follow-up wire winding module 4, a decoupling module 5, a photovoltaic energy storage module 6, a system controller 7 and a modular damping unit 8.

[0043] Integrated balance beams 2 are respectively provided at the four corners of the frame body 1. At both ends of the integrated balance beam 1, a posture adjustment module 3 and a follow-up wire winding module 4 are respectively provided. A sling 9 is provided at the end of the posture adjustment module 2. The posture adjustment module 2 is configured to be able to adjust the motion state of the sling 9. A decoupling device 5 is provided on the sling 9. The decoupling wire of the decoupling device 5 is wound and unwound through the follow-up wire winding module 4 and is configured to be elastically connected and matched with the follow-up wire winding module 4. The decoupling device 5 is configured to be able to fix and release the sling 9, so as to be able to accurately adjust the inclination angle of the object to be lifted and release the sling 9 at any angle, realizing the rapid separation of the sling and the object to be lifted and improving the overall reliability of this hanger.

[0044] Furthermore, a photovoltaic energy storage module 6, a modular damping unit 8 and a system controller 7 are also provided on the frame body 1. The photovoltaic energy storage module 6 can provide driving energy. The modular damping unit 8 is configured to be able to dissipate vibration energy to reduce the influence of wind load on the hanger. The system controller 7 is configured to be able to control the working states of the posture adjustment module 2, the follow-up wire winding module 4 and the decoupling device 5 to ensure the stable and reliable operation of this hanger.

[0045] See Figure 1 and Figure 2 , wherein, the frame body 1 is composed of a space steel structure truss. Integrated balance beams 2 are respectively arranged at the four corners of the frame body 1, and the object to be lifted can be synchronously lifted through the integrated balance beams 2. Moreover, the integrated balance beams 2 at the four corners can respectively adjust the motion state of the sling 9 through the corresponding posture adjustment modules 3, so that the corresponding slings 9 at the four corners cooperate to accurately adjust the inclination angle of the object to be lifted.

[0046] See Figure 2 and Figure 3 , specifically, the posture adjustment module 3 is hung under both ends of the integrated balance beam 2. The posture adjustment module 3 is composed of a posture adjustment electric hoist 301, preferably composed of a chain electric hoist. A hook 302 is provided at the bottom end of the chain electric hoist. The sling 9 is connected through the hook 302, so that the chain electric hoist can adjust the motion state of the sling 9 through the movement of the internal chain and control the lifting height of the sling 9 for the object to be lifted.

[0047] In this way, the integrated balance beams 2 at the four corners of the frame body 1 can synchronously lift the object to be lifted through the corresponding suspension ropes 9, and the corresponding posture adjustment modules 3 can respectively adjust the motion states of each suspension rope 9, so as to accurately adjust the distribution inclination angle of the object to be lifted and ensure the placement accuracy of the object to be lifted.

[0048] See Figure 4 , further, one end of the suspension rope 9 is connected and cooperated with the posture adjustment module 3, and the other end is connected and cooperated with the hook release device 5, so that the suspension rope 9 can drive the hook release device 5 to move synchronously, and the hook release device 5 is configured to fix and release the suspension rope 9, so that after the object to be lifted moves to the designed position, the hook release device 5 can release the suspension rope 9 and quickly separate the suspension rope 9 from the object to be lifted, so as to improve the reliability and lifting efficiency of this lifting frame.

[0049] See Figure 5 , specifically, the hook release device 5 includes a hook release device housing 501, a fixing component arranged outside the hook release device housing 501, a gear drive component arranged inside the hook release device housing 501, and a movable locking tongue 507. One end of the movable locking tongue 507 is cooperated with the gear drive component, and the other end extends out of the hook release device housing 501 and is in dynamic contact and cooperation with the fixing component, so that the fixing component, the gear drive component and the movable locking tongue 507 can cooperate with each other to realize the fixing and release of the suspension rope 9.

[0050] Wherein, the gear drive component includes a driven gear 502, a driving gear 503, a driving motor 504, a driven gear support 505 and a rack 506. The driven gear 502 is arranged in the hook release device housing 501 and connected to the driving motor 504, so that the driving motor 504 can drive the driving gear 503 to rotate. The driven gear 502 is arranged in the hook release device housing 501 through the driven gear support 505 and forms a gap with the driving gear 503, so that the rack 506 can be slidably arranged between the driven gear 502 and the driving gear 503. One side of the rack 506 meshes with the driving gear 503, and the other side meshes with the driven gear 502, so that the rotation of the driving gear 503 can drive the rack 506 to axially move between the driven gear 502 and the driving gear 503. At the same time, the rack 506 drives the driven gear 502 to rotate, so that the driven gear 502 can ensure the stable movement of the rack 506 without deviation.

[0051] Further, the end of the rack 506 is connected to the movable locking tongue 507, and a through hole adapted to the movable locking tongue 507 is formed at one end of the hook release device housing 501 in cooperation with the fixing component, so that the driving gear 503 drives the rack 506 to axially move towards the fixing component, which can drive the movable locking tongue 507 to synchronously axially move towards the fixing component, and extend out of the hook release device housing 501 through the through hole and abut against the fixing component.

[0052] In cooperation therewith, the fixing component includes a first fastener steel plate 508, a second fastener steel plate 509 and a fixing lock bolt 510. The first fastener steel plate 508 and the second fastener steel plate 509 are distributed oppositely. The fixing lock bolt 510 is arranged in one end area of the fastener steel plates and connects the first fastener steel plate 508 and the second fastener steel plate 509 respectively. A lock hole adapted to the movable lock tongue 507 is provided in the other end area of the second fastener steel plate 509. After the movable lock tongue 507 extends out of the decoupling device housing 501, it passes through the second fastener steel plate 509 and abuts against the first fastener steel plate 508, so that the movable lock tongue 507 cooperates with the first fastener steel plate 508 to realize the locking of the decoupling device 5.

[0053] Correspondingly, when the driving gear 503 drives the rack 506 to axially move away from the fixing component, it can drive the movable lock tongue 507 to axially move away from the fixing component synchronously, retract into the decoupling device housing 501, and no longer abut against the first fastener steel plate 508, realizing the unlocking of the decoupling device 5.

[0054] In this way, the decoupling device 5 can realize locking and unlocking through the dynamic contact and cooperation between the movable lock tongue 507 and the fixing component, so as to cooperate with the sling 9 to realize the fixing and releasing of the sling 9.

[0055] See Figure 4 and Figure 5 In cooperation therewith, the sling 9 includes a first sling 901 and a second sling 902. The two ends of the first sling 901 are respectively connected to the posture adjusting module 3 and the fixing lock bolt 510. The first end 9021 of the second sling 902 is connected to the posture adjusting module 3 (not shown in the figure), and the second end 9022 cooperates with the movable lock tongue 507 and is used to lift the object to be lifted, so that the locking and unlocking of the decoupling device 5 can correspondingly fix and release the second end 9022 of the second sling 902. Correspondingly, the first sling 901 is stably connected to the decoupling device 5, can drive the decoupling device 5 to move synchronously, and ensures that when the second sling 902 is released, the decoupling device 5 can still be stably connected to the first sling 901 and will not fall off.

[0056] As an example, the two ends of the first sling 901 are respectively connected to the posture adjusting module 3 and the fixing lock bolt 510. The first end 9021 of the second sling 902 is connected to the posture adjusting module 3, and the second end 9022 is hung on the movable lock tongue 507 and is connected to the object to be lifted for lifting. At this time, the driving motor 504 drives the driving gear 503 to rotate, drives the rack 506 to axially move towards the fixing component to drive the movable lock tongue 507 to axially move towards the fixing component synchronously, so that the movable lock tongue 507 extends out of the decoupling device housing 501 and abuts against the first fastener steel plate 508, realizing the locking of the decoupling device 5 and fixing the second sling 902.

[0057] At this time, the axial movement of the second end 9022 of the second sling 902 is limited by the first fastener steel plate 508 and the second fastener steel plate 509 and cannot fall off the movable locking tongue 507. Therefore, the object to be lifted is not easily separated from the second sling 902, and stable lifting can be carried out.

[0058] Further, the posture adjustment module 3 adjusts the movement states of the first sling 901 and the second sling 902, controls the lifting height and the distribution angle of the object to be lifted. After the object to be lifted moves to the designed position, the driving motor 504 drives the driving gear 503 to rotate in the reverse direction, drives the rack 506 to axially move away from the fixed assembly to drive the movable locking tongue 507 to synchronously axially move away from the fixed assembly, so that the movable locking tongue 507 retracts into the hook release device housing 501 and no longer abuts against the first fastener steel plate 508, realizing the unlocking of the hook release device 5 and releasing the second sling 902.

[0059] At this time, the second end 9022 of the second sling 902 can fall off the movable locking tongue 507. The posture adjustment module 3 only needs to finely adjust the movement state of the second sling 902, and then the second end 9022 of the second sling 902 can be misaligned with the object to be lifted, so as to separate the object to be lifted from the second sling 902, realizing the quick unhooking of the object to be lifted and improving the lifting efficiency.

[0060] In this way, the hook release device 5 can cooperate with the sling 9 and the posture adjustment module 3 to realize the angle adjustment and quick unhooking of the object to be lifted. In order to realize the stable operation of the hook release device 5, the hook release device 5 further includes a hook release wire 511. One end of the hook release wire 511 is connected to the driving motor 504, and the other end is connected to the photovoltaic energy storage module 6 and the system controller 7 arranged on the frame 1 for power supply and control.

[0061] The movement of the sling 9 will drive the hook release wire 511 to move synchronously, resulting in height and angle changes of the hook release wire 511, which are likely to be entangled with the sling 9 and the chain of the electric chain hoist, causing unstable circuits. In order to ensure the stable operation of the hook release wire 511, the lifting frame further includes a follow-up wire winding module 4. The follow-up wire winding module 4 is configured to be able to wind and unwind the hook release wire 511, and can also be elastically connected and cooperated with the hook release wire 511 to keep the hook release wire 511 in a taut state, ensuring the stable circuit of the hook release wire 511 and preventing it from being entangled with the sling 9.

[0062] See Figure 4 and Figure 6, specifically, the follow-up wire winding module 4 is horizontally distributed at both ends of the integrated balance beam 2 and is arranged above the posture adjustment module 3 for facilitating the cooperation with the decoupling wire 511. The follow-up wire winding module 4 includes a wire winding module base 401, a spring winding 402, a wire winding module shaft 403, a winding drum 404, and a wire winding connection box 408. One end of the wire winding module base 401 is horizontally connected and distributed with the end of the integrated balance beam 2, and the other end is connected to the wire winding module shaft 403. A spring winding 402 and a winding drum 404 are respectively arranged in the middle area of the wire winding module shaft 403. A wire winding connection box 408 for cooperating with the decoupling wire 511 is arranged at the end of the wire winding module shaft 403 that cooperates with the integrated balance beam 2. At the same time, a through hole for the decoupling wire 511 to pass through is also arranged on the wire winding module shaft 403.

[0063] In this way, one end of the decoupling wire 511 is connected to the driving motor drive motor 504, and the other end can be wound around the winding drum 404, pass through the through hole on the wire winding module shaft 403 and enter the wire winding connection box 408, and then be connected to the photovoltaic energy storage module 6 and the system controller 7 after passing through the wire winding connection box 408.

[0064] At the same time, the rotation of the winding drum 404 around the wire winding module shaft 403 can realize the winding and unwinding of the decoupling wire 511. Synchronously, the spring winding 402 will be tightened by the rotational force of the winding drum 404 and apply a reverse torque to the winding drum 404.

[0065] Here, the spring winding 402 and the winding drum 404 are conventional technical means in the art and will not be elaborated here.

[0066] Furthermore, an electromagnetic clutch 405, a servo motor 406, and a motor connection box 407 are arranged at the end of the wire winding module shaft 403 far from the integrated balance beam 2. One end of the servo motor 406 is connected to the winding drum 404, and the other end is connected to the photovoltaic energy storage module 6 and the system controller 7 through the motor connection box 407 for power supply and control to control the motion state of the winding drum 404.

[0067] Specifically, a torque sensor is built in the electromagnetic clutch 405. The torque sensor can detect the pulling force value generated by the decoupling wire 511 on the winding drum 404 in real time. When it detects that the pulling force exceeds the preset pulling force threshold of the torque sensor, a torque signal will be generated and fed back to the system controller 7, so that the system controller 7 controls the motion state of the winding drum 404 through the servo motor 406, thereby winding and unwinding the decoupling wire 511. At the same time, the motion state of the winding drum 404 will generate a rotational force on the spring winding 402, causing the spring winding 402 to tighten and apply a reverse torque to the winding drum 404, elastically connecting and cooperating the winding drum 404 with the decoupling wire 511, keeping the decoupling wire 511 taut, and preventing the decoupling wire 511 from winding around the sling 9.

[0068] As an example, when the posture adjustment module 3 adjusts the sling 9 to drive the unhooking wire 511 to move away from the integrated shoulder pole beam 2 or adjusts the angle of the unhooking wire 511, the unhooking wire 51 is in a tensioned state, generating a pulling force on the reel 404. When the torque sensor in the electromagnetic clutch 405 detects that the pulling force exceeds the pulling force threshold, a torque signal will be generated and fed back to the system controller 7, so that the system controller 7 controls the reel 404 to rotate around the wire taking-up module shaft 403 through the servo motor 406, and pays out the unhooking wire 511 on the reel 404 to meet the length required for the unhooking wire 511 to move away from the integrated shoulder pole beam 2 or adjust the angle.

[0069] At the same time, the rotation of the reel 404 will drive the spring spring 402 to rotate synchronously around the take-up module shaft 403, so that the spring spring 402 is tightened and the elastic force is stored.

[0070] Furthermore, when the posture adjustment module 3 stops running and the sling 9 no longer drives the unhooking wire 511 to move synchronously, the unhooking wire 511 changes from a tensioned state to a relaxed state, and the unhooking wire 511 no longer generates a pulling force on the reel 404. At this time, the torque sensor in the electromagnetic clutch 405 detects that the pulling force is less than the pulling force threshold, and no longer generates a torque signal to feed back to the system controller 7, so that the system controller 7 no longer controls the rotation of the reel 404 through the servo motor 406.

[0071] At the same time, the spring spring 402 releases its elastic force under the action of its own elastic restoring force, generating a reverse torque on the reel 404, driving the reel 404 to rotate in the opposite direction, winding the relaxed part of the unhooked wire 511 on the reel 404, so that the unhooked wire 511 remains taut without being entangled or curled.

[0072] Correspondingly, when the posture adjustment module 3 adjusts the sling 9 to drive the unhooking wire 511 to move toward the integrated shoulder pole beam 2, the spring spring 402 releases the elastic force under the action of its own elastic restoring force, and will continuously generate torque on the reel 404, driving the reel 404 to rotate, winding and retracting the unhooking wire 511, ensuring that the unhooking wire 511 remains taut without entanglement and curling.

[0073] The follow-up wire collection module 4 thus constructed cooperates with the unhooking wire 511 to realize dynamic retraction and release of the unhooking wire 511 and keep the unhooking wire 511 in a taut state to ensure stable operation of the unhooking device 5 and stably realize the unhooking of the sling 9.

[0074] When the posture adjustment module 3 drives the sling 9 to lift the object, the frame 1 as a whole will shake due to the influence of wind load, resulting in lifting deviation. In order to improve the stability of the hanger, the hanger also includes a modular vibration reduction unit 8. The modular vibration reduction unit 8 is configured to be able to consume energy by vibration and reduce the influence of wind load.

[0075] Combined with Figure 2 and Figure 7 , specifically, the modular damping unit 8 is arranged at the bottom end of the frame body 1, and includes a damping unit housing 801, a damping unit spring 802, a damping unit chute 803, a damping unit mass 804 and a short-direction cavity 805. The damping unit mass 804 is arranged inside the damping unit housing 801, and the damping unit spring 802 is arranged between the damping unit mass 804 and the damping unit housing 801. Preferably, a plurality of damping unit springs 802 are distributed on both short sides of the damping unit mass 804, and one end of the damping unit spring 802 is connected to the damping unit mass 804, and the other end is connected to the inner side surface of the damping unit housing 801, so that the damping unit mass 804 can reciprocate axially inside the damping unit housing 801 when receiving vibration, driving the damping unit spring 802 to reciprocate and stretch, realizing energy consumption.

[0076] Furthermore, a plurality of damping unit chutes 803 are respectively distributed on the inner top surface and the inner bottom surface of the damping unit housing 801 and are distributed along the short direction of the damping unit mass 804. A plurality of slide rails 8041 adapted to the damping unit chutes 803 are also arranged on both sides of the damping unit mass 804, so that the damping unit mass 804 forms a plurality of groups of sliding pairs through the cooperation of the slide rails 8041 and the damping unit chutes 803, and the damping unit mass 804 can axially move along the damping unit chutes 803. Cooperating with the damping unit spring 802, a tuned mass damper device can be formed in the short direction of the modular damping unit 8, which can effectively carry out vibration energy consumption.

[0077] At the same time, a short-direction cavity 805 is formed between the damping unit mass 804 and the inner side surface of the damping unit housing 801, and damping liquid, such as organic compounds such as silicone oil and glycerol, is filled in the short-direction cavity 805, which can reduce the axial movement efficiency of the damping unit mass 804 and effectively improve the energy consumption effect, thereby reducing the influence of wind load on this hanging rack.

[0078] Here, the mass of the damping unit mass 804, the stiffness of the damping unit spring 802 and the damping liquid coefficient can be adaptively adjusted according to specific applications, so as to effectively reduce the high-altitude vibration of the frame body 1 under the action of wind load and improve the stability of this hanging rack.

[0079] Combined with Figure 1 and Figure 2 , furthermore, this hanging rack further includes a photovoltaic energy storage module 6 and a system controller 7. Preferably, the photovoltaic energy storage module 6 and the system controller 7 are respectively symmetrically arranged on the long sides of the frame body 1. The photovoltaic energy storage module 6 is respectively connected to the posture adjustment module 3, the follow-up wire winding module 4 and the unhooking module 5, and can provide driving energy for the posture adjustment module 3, the follow-up wire winding module 4 and the unhooking module 5, thus reducing the problems of pulling wires and manual charging.

[0080] Here, the photovoltaic energy storage module 6 is a conventional technical means in the art and will not be elaborated here. As an example, the photovoltaic energy storage module 6 can be composed of existing photovoltaic panels.

[0081] Furthermore, the system controller 7 is respectively connected to the attitude adjustment module 3, the follow-up wire winding module 4 and the decoupling module 5, and can control the working states of the attitude adjustment module 3, the follow-up wire winding module 4 and the decoupling module 5, so that the attitude adjustment module 3, the follow-up wire winding module 4 and the decoupling module 5 cooperate with each other to ensure the stable operation of this hanging rack.

[0082] Here, the system controller 7 is a conventional technical means in the art and will not be elaborated here. As an example, the system controller 7 can be composed of an existing PLC module.

[0083] Thus, the large-scale distribution hanging rack for offshore photovoltaic attitude adjustment, decoupling and vibration reduction provided by the present invention is constituted.

[0084] Combined with Figure 8 , furthermore, the present invention also provides a hoisting method for a large-scale distribution hanging rack for offshore photovoltaic attitude adjustment, decoupling and vibration reduction. Based on the large-scale distribution hanging rack for offshore photovoltaic attitude adjustment, decoupling and vibration reduction constituted by the above solution, this hoisting method includes:

[0085] S1: The system controller 7 controls the decoupling device 5 to fix the sling 9, hoists the object to be hoisted through the sling 9, and the modular vibration reduction unit 8 synchronously generates vibration energy consumption to reduce the influence of wind load.

[0086] Specifically, first, place the frame body 1 near the object to be hoisted, and connect the two ends of the first sling 901 in the sling 9 to the attitude adjustment module 3 and the fixed locking bolt 510 respectively, and the first end 9021 of the second sling 902 is connected to the attitude adjustment module 3.

[0087] Then, move the frame body 1 above the object to be hoisted through a crane, and slowly lower the frame body 1 so that the lower ends of the first sling 901 and the second sling 902 fall near the lifting points of the object to be hoisted.

[0088] At this time, hang the second end 9022 of the second sling 902 on the movable locking tongue 507. The system controller 7 controls the drive motor 504 of the decoupling device 5 to drive the drive gear 503 to rotate, drive the rack 506 to axially move towards the fixed component to drive the movable locking tongue 507 to synchronously axially move towards the fixed component, so that the movable locking tongue 507 extends out of the decoupling device housing 501 and abuts against the first fastener steel plate 508 to realize the locking of the decoupling device 5 and fix the second sling 902.

[0089] By then, the second end 9022 of the second sling 902 can be hoisting-connected to the object to be hoisted, and the attitude adjustment module 3 adjusts the movement state of the sling 9 to hoist the object to be hoisted.

[0090] Meanwhile, the modular vibration damping unit 8 vibrates and dissipates energy synchronously under the wind load, reducing the influence of the wind load to reduce the swing of the frame 1 and the object to be lifted, ensuring the stability of the lifting.

[0091] S2: The system controller 7 controls the posture adjustment module 3 to adjust the motion state of the sling 9, and the follow-up wire winding module 4 synchronously winds and unwinds the unhooking wire 511, and keeps the unhooking wire 511 in a taut state.

[0092] The posture adjustment electric hoist 301 of the posture adjustment module 3 adjusts the motion state of the sling 9, controls the lifting height of the object to be lifted by the sling 9. The integrated lifting beam 2 at the four corners of the frame 1 can lift the object to be lifted synchronously through the corresponding sling 9, and respectively adjust the motion state of each sling 9 through the corresponding posture adjustment module 3, so as to accurately adjust the distribution inclination angle of the object to be lifted and ensure the placement accuracy of the object to be lifted.

[0093] Synchronously, the posture adjustment module 3 adjusts the sling 9 to drive the unhooking wire 511 to move away from the integrated lifting beam 2 or adjusts the angle of the unhooking wire 511. The unhooking wire 51 is in a tensioned state, generating a pulling force on the drum 404. When the torque sensor in the electromagnetic clutch 405 detects that the pulling force exceeds the pulling force threshold, a torque signal will be generated and fed back to the system controller 7, so that the system controller 7 controls the drum 404 to rotate around the wire winding module shaft 403 through the servo motor 406, and pays out the unhooking wire 511 on the drum 404 to meet the length required for the unhooking wire 511 to move away from the integrated lifting beam 2 or adjust the angle.

[0094] Meanwhile, the rotation of the drum 404 will drive the spring mainspring 402 to rotate around the wire winding module shaft 403 synchronously, so that the spring mainspring 402 is tightened and stores elastic force.

[0095] Furthermore, when the posture adjustment module 3 stops operating and the sling 9 no longer drives the unhooking wire 511 to move synchronously, the unhooking wire 511 changes from a tensioned state to a relaxed state, and the unhooking wire 511 no longer generates a pulling force on the drum 404. At this time, the torque sensor in the electromagnetic clutch 405 detects that the pulling force is less than the pulling force threshold and no longer generates a torque signal to feedback to the system controller 7, so that the system controller 7 no longer controls the rotation of the drum 404 through the servo motor 406.

[0096] Meanwhile, the spring mainspring 402 releases elastic force under the action of its own elastic restoring force, generating a reverse torque on the drum 404, driving the drum 404 to rotate in the reverse direction, and coiling the relaxed part of the unhooking wire 511 on the drum 404, so that the unhooking wire 511 remains taut and will not be entangled and curled.

[0097] S3: After the object to be lifted moves to the designed position, the system controller 7 controls the hook release device 5 to release the sling 9, separates the sling 9 from the object to be lifted, and controls the posture adjustment module 3 to adjust the movement state of the sling, reset the sling, and the follow-up wire rewinding module 4 synchronously winds and unwinds the hook release wire.

[0098] Specifically, after the object to be lifted moves to the designed position, the crane slowly lowers the frame 1 so that the sling 9 no longer hoists the object to be lifted and only bears its own weight. The system controller 7 controls the driving motor 504 to drive the driving gear 503 to rotate in the reverse direction, drives the rack 506 to axially move away from the fixed component to drive the movable locking tongue 507 to synchronously move axially away from the fixed component, so that the movable locking tongue 507 retracts into the hook release device housing 501 and no longer abuts against the first fastener steel plate 508, realizing the unlocking of the hook release device 5 and releasing the second sling 902.

[0099] At this time, the second end 9022 of the second sling 902 can fall off the movable locking tongue 507. The system controller 7 controls the posture adjustment module 3 to finely adjust the movement state of the second sling 902. Or, when the crane raises the frame 1, the second end 9022 of the second sling 902 can be misaligned with the object to be lifted, thereby separating the object to be lifted from the second sling 902 and realizing the quick unhooking of the object to be lifted to improve the hoisting efficiency.

[0100] Further, the posture adjustment module 3 adjusts the sling 9 to drive the hook release wire 511 to move towards the integrated spreader beam 2. The spring mainspring 402 generates a reverse torque on the reel 404, drives the reel 404 to rotate in the reverse direction, and winds and retracts the hook release wire 511 to ensure that the hook release wire 511 remains taut and does not get entangled or coiled.

[0101] Finally, the crane moves the frame 1 to the next position to prepare for hoisting the next object.

[0102] The large-scale distributing hanger for adjusting posture, unhooking and damping vibration of offshore photovoltaic and the hoisting method provided by the present invention adopt the posture adjustment module to adjust the movement state of the sling. Through the cooperation of the slings corresponding to the integrated spreader beams at the four corners, the inclination angle of the object to be lifted can be accurately adjusted. Through the cooperation of the follow-up wire rewinding module and the hook release device, the sling can be released at any angle, realizing the quick separation of the sling and the object to be lifted. At the same time, the follow-up wire rewinding module can wind and unwind the hook release wire of the hook release device, and elastically connect and cooperate with the hook release wire to keep the hook release wire in a taut state, preventing the hook release wire from getting entangled with the sling, thereby improving the reliability of this hanger.

[0103] Further, the modular damping unit on the frame synchronously realizes the high-altitude damping of the frame, reduces the influence of wind load on the hanger, and improves the stability of this hanger.

[0104] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present invention.
