Description

Technical Field

[0001] The present invention relates to the technical field of offshore wind power installation, and in particular to a transport tool for a wind turbine foundation buoy and a transport method thereof. Background Art

[0002] In recent years, with the rapid development of marine renewable energy, as one of the most promising renewable energy sources with the largest scale of development and the most promising commercial development prospects, the scope of offshore wind power development has gradually expanded from shallow offshore to deep sea. Common deep-sea wind turbine foundations generally adopt the method of towing the whole machine, that is, the floating foundation is manufactured in the shipyard, assembled at the shore dock, and then the floating wind turbine foundation is deployed to the designated operating sea area by transport ships. Due to the long construction and welding time of the floating foundation in the shipyard, and the large size after assembly, it is difficult to transport. Therefore, in order to reduce the difficulty and cost of transportation, the current floating wind turbine foundation is also assembled and deployed in an offshore dock. The floating wind turbine foundation is divided into multiple modules, transported to the designated deployment sea area by transport ships, and the modules are spliced and deployed at sea by the crane of the operating ship.

[0003] However, after the foundation is split into multiple modules, they are usually laid out in partitions for stacking in the offshore dock, and the lifting equipment grabs and lifts them for assembly as needed; this results in the occupation of available space on the dock deck. At the same time, the lifting equipment's boom length needs to be longer to grab the foundation modules over a large area, making it difficult to achieve low-altitude lifting operations and miniaturization of the lifting equipment.

[0004] Therefore, how to better stack and transport modules such as wind turbine foundation buoys, reduce the area occupied by offshore docks, and reduce the limitations of lifting equipment has become a research and development focus. Summary of the Invention

[0005] In order to solve the technical problems existing in the above-mentioned prior art, one of the purposes of the present invention is to provide a transport tooling for wind turbine foundation pontoons. By setting up a conveying bracket, the pontoons can be circulated and transported in the vertical direction, maximizing the use of vertical storage space, saving the available space on the offshore dock deck, and eliminating the need to set up a longer boom to grab and lift the wind turbine foundation module on a large scale. The volume and occupied space of the lifting equipment are reduced, the lifting height of the foundation module assembly is reduced, and the center of gravity height of the lifting equipment is reduced, thereby reducing the impact of wind resistance on the foundation assembly process, avoiding shaking and other problems, improving the stability of the equipment and expanding the operable weather window; at the same time, it saves more energy consumption of the lifting equipment.

[0006] The second object of the present invention is to provide a method for transporting a transport tool for a wind turbine foundation buoy.

[0010] When the transmission assembly drives the placement assembly to move and transport the buoy to the position, the lifting drive mechanism drives the support frame to move to dock with the placement plate and transfers the buoy to the assembly station.

[0011] Furthermore, the support frame includes a supporting side plate and a plurality of supporting bars spaced apart on the supporting side plates; the placement plate is vertically penetrated by a dislocation groove adapted to the width of the supporting bar; and an escape cavity is formed below the supporting bar for the placement plate to be able to move telescopically;

[0014] Furthermore, a limiting recess is provided downwardly on the upper surface of the placement bar, and a plurality of the limiting recesses are arranged to form a limiting groove that is adapted to the end surface of the buoy.

[0016] Furthermore, rollers are provided at the ends of the placement bars, and the rollers of the placement bars on both sides are in rolling contact with the outer side wall of the first slide rail or the inner walls of the left plate and the right plate respectively.

[0019] Furthermore, the conveying bracket includes a front bracket and a rear bracket arranged at intervals; the circulating guide rail and the connecting plate are provided on opposite sides of the front bracket and the rear bracket; the suspension assembly includes a suspension link whose two ends are rotatably connected to the two connecting plates respectively; the placement plate is installed under the suspension link through a suspension rod.

[0020] Furthermore, a circulating chain is provided on the circulating guide rail, and the connecting plate is provided on the circulating chain; the circulating driving mechanism includes a driving motor provided on the front bracket / rear bracket and a sprocket connected to the output shaft of the driving motor; the circulating chain is provided with a limiting boss for fixing the connecting plate, and the sprocket is circumferentially provided with a limiting slot engaged with the limiting boss for transmission; the driving motor drives the sprocket to rotate and drives the circulating chain to move along the circulating guide rail through the engagement of the limiting slot and the limiting boss, thereby driving the suspension assembly and the placement plate to circulate between the front bracket and the rear bracket through the connecting plate on the circulating chain.

[0021] The second object of the present invention is achieved through the following technical solutions:

[0022] A method for transporting a transport tool for a wind turbine foundation buoy comprises the following steps:

[0023] Circular conveying step: the circulating driving mechanism drives the sprocket to rotate and drives the circulating chain to move along the circulating guide rail, thereby driving the suspension assembly and the placement plate to circulate between the front bracket and the rear bracket through the connecting plate on the circulating chain;

[0024] Lifting and docking step: after the buoy is delivered to its place, the placement plate extends above the support frame; the lifting drive mechanism drives the support frame to rise, and the support bar passes through the dislocation groove from bottom to top, lifting the buoy off the placement plate, and the placement plate retreats to the placement plate through the avoidance cavity, completing the docking of the buoys;

[0025] Horizontal transfer step: the supporting frame and the buoy that have completed the jacking and docking slide along the transfer trough driven by the sliding plate, and the buoy is transferred to the assembly station and lifted and assembled by the lifting equipment.

[0026] Compared with the prior art, the present invention has at least the following beneficial effects:

[0027] 1. The present invention provides a conveying bracket to achieve vertical circulation of the buoy, maximizing the use of vertical storage space and saving available space on the offshore dock deck. This eliminates the need for a longer boom to lift the wind turbine foundation module over a wide area, reducing the size and space occupied by the lifting equipment, lowering the lifting height for assembling the foundation module and, in turn, the center of gravity of the lifting equipment. This reduces the impact of wind resistance on the foundation assembly process, avoids shaking and other problems, improves the stability of the equipment, and expands the operational weather window. Furthermore, it also saves energy consumption during the operation of the lifting equipment.

[0028] The advantage of vertical circulating conveying of fan buoys is that it avoids the storage and grabbing restrictions of buoys in fixed module stacking racks in the existing technology. The buoy conveying efficiency can be adjusted according to the assembly rhythm. It is fast, controllable, flexible and highly intelligent.

[0029] 2. Furthermore, the docking and transfer structure of the placement assembly and the transfer assembly is cleverly designed, utilizing the misaligned fit between the offset grooves of the retractable placement plate and the support bars on the liftable support frame. Once the buoy is delivered to its proper location, it is only necessary to raise the support frame to allow the support bars to pass through the offset grooves of the placement plate, completing the misaligned lifting and lowering of the support frame and the placement plate. After docking, the placement plate can be retracted from the avoidance cavity of the support frame, simultaneously achieving the expansion and contraction of the placement plate and the lifting and docking of the buoy. This design allows for the stable transfer of the buoy from the placement assembly to the transfer assembly without the need for an additional grabbing mechanism, reducing the space occupied by the additional grabbing mechanism, simplifying the transfer structure, significantly reducing equipment costs, and enhancing practicality.

[0030] On the other hand, the placement assembly and transfer assembly of the present invention can be applied to wind turbine components other than wind turbine foundation buoys. The wind turbine components to be assembled only need to be placed on the placement plate of each placement assembly without additional customized settings or structural changes. This can adapt to wind turbine components of different specifications and volumes, thereby improving the flexibility of wind turbine assembly and making it more versatile.

[0031] 3. The pontoon transportation method of the present invention is easy to operate and has few steps. Since a vertical circulating conveying bracket is provided with a placement component with strong versatility, the difficulty of storing and conveying the pontoon is reduced, and the conveying step is faster. Furthermore, since the transfer component is provided with a support frame that can be staggered, lifted and docked with the placement plate, after the pontoon is transported to its place, it is only necessary to lift the support frame so that the support bar passes through the staggered groove of the placement plate, and the staggered lifting and lowering of the support frame and the placement plate are completed to complete the operation of transferring the pontoon to the support frame. No redundant grasping steps are required, and the method is fast and stable. After the pontoon docking is completed, the support frame can be transferred to the basic assembly station driven by the sliding plate, which greatly improves the efficiency of pontoon transportation.

[0032] On the other hand, the docking of the placement plate and the support frame and the movement of the sliding plate on the transfer trough are all carried out at low altitude on the deck of the offshore dock, thereby further improving the assembly stability and reducing the wind resistance and safety hazards of high-altitude operations.

[0055] like Figure 1-13 As shown, the present invention provides a transport tool for a wind turbine foundation buoy, which is used to transport the wind turbine foundation buoy 20 during the wind turbine foundation assembly operation in an offshore dock 10. The present invention can also be applied to the transportation of other offshore wind power accessories, including but not limited to the connecting aisles of the wind turbine foundation and the wind turbine nacelle. The present invention is described using the wind turbine foundation buoy as an example:

[0056] The transport tooling includes a transport support 1 for cyclically transporting the buoys in a vertical direction; the transport support 1 is provided with a plurality of placement components 2 for placing the buoys and a transmission component 3 for driving the placement components 2 to cyclically move; a transfer component 4 is provided below the transport support 1 for docking with the placement components 2 and transferring the buoys to the assembly station;

[0057] The transmission assembly 3 includes a circulating guide rail 31 mounted on the conveying support 1, a connecting plate 32 movable along the circulating guide rail 31, and a circulating drive mechanism 33 for driving the connecting plate 32. Specifically, the circulating guide rail 31 has curved sections at both ends, with straight sections on both sides. The circulating drive mechanism 33 is located at the curved section at the upper or lower end. In this embodiment, a circumferential groove can be provided on the circulating guide rail 31, and the connecting plate 32 can be slidably connected to the circulating guide rail 31 via a connector 35 that can slide within the upper limit of the groove.

[0058] The placement assembly 2 includes a suspension assembly 21 connected to the connecting plate 32 and a placement plate 22 mounted on the suspension assembly 21. The placement plate 22 is provided with a placement plate 221 for placing the buoy, and the placement plate 221 is retractably mounted on the placement plate 22. In further detail, the placement assembly 2 can be provided in the form of a cage / basket. The suspension assembly 21 is hung on the connecting plate 32 and moves with the connecting plate 32. The placement plate 22 is a cylindrical or cubic disk structure having an upper opening and a side opening. The side opening is provided for the horizontal extension and retraction of the placement plate 221. It should be noted that in this embodiment, a power component for driving the extension and retraction of the placement plate 221 can be provided on the side of the placement plate 22 away from the side opening. The power component can be a motor, a screw rod, a pneumatic cylinder, an oil cylinder, etc. The present invention is not limited to this. As long as it can achieve the beneficial effect of driving the extension and retraction of the placement plate 221, it can be implemented.

[0059] The transfer assembly 4 includes a lifting support frame 41 for docking with the placement plate 221 and transferring the position of the buoy, and a lifting drive mechanism 42 for driving the support frame 41 to move;

[0060] When the transmission component 3 drives the placement component 2 to move and transport the buoy to the position, the jacking drive mechanism 42 drives the support frame 41 to move to dock with the placement plate 221 and transfer the buoy to the assembly station.

[0061] Specifically, the support frame 41 includes a supporting side plate 411 and a plurality of supporting bars 412 spaced apart on the supporting side plate 411. The placement plate 221 is vertically penetrated by a staggered groove 2211 that matches the width of the supporting bar 412. An escape cavity 413 is formed below the supporting bar 412 to allow the placement plate 221 to move telescopically.

[0062] After the buoy is delivered to its proper position, the placement plate 221 extends above the support frame 41; the lifting drive mechanism 42 drives the support frame 41 to rise, and the support bar 412 passes through the offset groove 2211 from bottom to top, lifting the buoy off the placement plate 221 and completing the docking of the buoy. In this embodiment, the support bar 412 can be arranged to extend laterally at the top of the supporting side plate 411, located above the avoidance space; after the placement plate 221 is extended, the offset groove 2211 on the placement plate 221 is exactly located directly above the support bar 412. In this way, when the support frame 41 is raised, the support bar 412 passes through the corresponding offset groove 2211 from bottom to top. During this process, the support frame 41 and the placement plate 221 will not interfere with each other. Finally, the height of the support bar 412 is higher than the height of the placement plate 221, and the buoy placed on the upper surface of the placement plate 221 can be lifted off the surface of the placement plate 221.

[0063] To facilitate the staggered docking of the support frame 41 and the placement plate 221, as a further preferred embodiment, the support side plate 411 includes a left side plate 4111 and a right side plate 4112. In this embodiment, the left side plate 4111 and the right side plate 4112 are spaced apart. A plurality of support bars 412 are formed by bending the tops of the left side plate 4111 and the right side plate 4112 in opposite directions. The placement plate 221 includes an "I"-shaped body 2212 and placement bars 2213 disposed on both sides of the body 2212, with the staggered slot 2211 formed between the two placement bars 2213. In this embodiment, to prevent motion interference between the placement plate 221 and the support frame 41, the opposing ends of the support bars 412 on the left side plate 4111 and the support bars 412 on the right side plate 4112 are provided with a gap to avoid the "I"-shaped body 2212. When the support frame 41 is raised, it passes through the staggered slots 2211 on both sides of the "I"-shaped body 2212. Then, the placement plate 221 can be put into the avoidance space and then retreated.

[0064] In order to improve the stability of the placement of the buoy, as a further preferred solution, a limiting recess 22131 is provided downward on the upper surface of the placement bar 2213, and a plurality of the limiting recesses 22131 are surrounded to form a limiting groove 2214 that is compatible with the end face of the buoy.

[0065] The telescopic method of the placement plate 221 is further introduced. The inner walls on both sides of the placement plate 22 are respectively provided with first slide rails 222, and the rear ends of the outer walls on both sides of the placement plate 221 are respectively provided with first sliders 223 matching the first slide rails 222; the first slider 223 is provided with first protrusions 2231 opposite to each other up and down, and the first slide rail 222 is provided with a first groove 2221 matching the first protrusion 2231; the cross-sectional shape of the first slide rail 222 is roughly "H"-shaped or flat-lying "T"-shaped, and the first slider 223 is slidably clamped on the first slide rail 222 through the cooperation of the first protrusion 2231 and the first groove 2221, and the upper and lower first protrusions 2231 of the first slider 223 are clamped in the corresponding first grooves 2221, and the overall connection is more stable.

[0066] To further enhance the smooth extension and retraction of the placement plate 221 and reduce friction, as a further preferred embodiment, rollers 2215 are provided at the ends of the placement bars 2213. The rollers 2215 of the placement bars 2213 on either side respectively roll in contact with the outer sidewalls of the first slide rail 222 or the inner walls of the left and right plates 4111 and 4112. When the placement plate 221 is extended, the first slider 223 slides on the first slide rail 222, while the rollers 2215 roll in contact with the outer sidewalls of the first slide rail 222, thereby enhancing the stability of the extension of the placement plate 221. When the support frame 41 and the placement plate 221 are displaced and docked, the placement plate 221 enters the avoidance cavity 413 formed by the left and right plates 4111 and 4112, and the rollers 2215 on either side can roll back along the inner walls of the left and right plates 4111 and 4112.

[0067] As a further preferred embodiment, the transport tooling also includes a base 5 arranged under the conveying bracket 1; a transfer trough 51 is provided on the base 5 along the transfer direction of the float, and the transfer component 4 includes a sliding plate 43 slidably arranged on the transfer trough 51; the jacking drive mechanism 42 includes at least one jacking cylinder; the jacking cylinder is arranged on the sliding plate 43, and the base 5 is provided to improve the assembly stability of the present invention.

[0068] To improve the stability of the sliding plate 43 as it moves along the transfer chute 51, as a further preferred embodiment, second rails 52 are provided on both sides of the transfer chute 51. Second sliders 431 are provided on the outer walls of both sides of the sliding plate 43, respectively, to match the second rails 52. The second sliders 431 are provided with second protrusions 4311 that oppose each other vertically, and the second rails 52 are provided with second grooves 521 that match the second protrusions 4311. The second sliders 431 are slidably clamped onto the second rails 52 through the mating engagement of the second protrusions 4311 and the second grooves 521. In this embodiment, the structure and configuration of the second rails 52 and second sliders 431 can be referenced to those of the first rails 222 and second sliders 431, and will not be repeated here.

[0069] Similarly, a power component for driving the sliding plate 43 to move can be provided on the transfer trough 51, and the power component can be a motor, a screw rod, a cylinder, an oil cylinder, etc. The present invention does not limit this, as long as it can meet the beneficial effect of driving the placement plate 221 to extend and retract.

[0070] As a further preferred embodiment, the conveying bracket 1 includes a front bracket 11 and a rear bracket 12 that are spaced apart; the opposite sides of the front bracket 11 and the rear bracket 12 are provided with the circulating guide rail 31 and the connecting plate 32; the suspension assembly 21 includes a suspension link 211 whose two ends are rotatably connected to the two connecting plates 32; the placement tray 22 is installed below the suspension link 211 through the suspension link 212. In this embodiment, one end of the suspension link 211 is connected to the connecting plate 32 provided on the front bracket 11, and the other end is connected to the connecting plate 32 provided on the rear bracket 12. The space between the front bracket 11 and the rear bracket 12 is the space for the placement assembly 2 to circulate and transport. In this way, the center of gravity is centered and the structure is more stable. The rotational connection between the suspension link 211 and the connecting plate 32 ensures that the upper surface of the placement tray 22 of the placement assembly 2 is always facing upward during the circulation process.

[0071] The docking and transfer structure design of the placement component 2 and the transfer component 4 of the present invention is ingenious. It utilizes the misaligned cooperation between the offset groove 2211 of the retractable placement plate 221 and the support bar 412 on the liftable support frame 41. When the buoy is transported to its place, it is only necessary to lift the support frame 41 so that the support bar 412 passes through the misaligned groove 2211 of the placement plate 221 to complete the misaligned lifting and lowering of the support frame 41 and the placement plate 221. After the docking is completed, the placement plate 221 can be retracted from the avoidance cavity 413 of the support frame 41, and the expansion and contraction of the placement plate 221 and the lifting and docking of the buoy can be achieved simultaneously. This design can achieve the stable transfer of the buoy from the placement component 2 to the transfer component 4 without the need for an additional grabbing mechanism, which not only reduces the space occupied by the additional grabbing mechanism, but also simplifies the transfer structure, greatly reduces the equipment cost, and is more practical.

[0072] On the other hand, the placement component 2 and transfer component 4 of the present invention can be applied to wind power components other than wind turbine foundation pontoons. It is only necessary to place the wind power components to be assembled on the placement plate 221 of each placement component 2 without the need for additional customized settings or structural changes. It can adapt to wind power components of different specifications and volumes, thereby improving the flexibility of wind power assembly and making it more versatile.

[0073] As a further preferred embodiment, a circulating chain 34 is provided on the circulating guide rail 31, and the connecting plate 32 is provided on the circulating chain 34; the circulating driving mechanism 33 includes a driving motor 331 provided on the front bracket 11 / rear bracket 12 and a sprocket 332 connected to the output shaft of the driving motor 331; the circulating chain 34 is provided with a limiting boss 341 for fixing the connecting plate 32, and the sprocket 332 is provided with a limiting slot 3321 on the circumference of the sprocket for engaging and transmitting with the limiting boss 341; the driving motor 331 drives the sprocket 332 to rotate and drives the circulating chain 34 to move along the circulating guide rail 31 through the engagement of the limiting slot 3321 with the limiting boss 341, thereby driving the suspension assembly 21 and the placement plate 22 to circulate between the front bracket 11 and the rear bracket 12 through the connecting plate 32 on the circulating chain 34.

[0074] Specifically, the sprocket 332 pulls the circulating sprocket 332 through the limiting boss 341 engaged with the sprocket 332, which has the advantage of a simpler structure and a more stable rigid connection.

[0075] In this embodiment, the circulating guide rail 31 has curved sections at both ends, with straight sections on both sides. The drive motor 331 and sprocket 332 are arranged at the upper or lower curved sections. The circulating guide rail 31 can be provided with a circumferential slot, and the connecting plate 32 can be slidably connected to the circulating guide rail 31 via a connector 35 that can slide within the slot to a certain limit. The connector 35 can be integrally formed with the limiting boss 341.

[0076] In this embodiment, the connecting plate 32 is a triangular connecting plate 32, and the two corners of the connecting plate 32 are connected to the circulating sprocket 332 through the connecting member 35. The third corner of the connecting plate 32 is outwardly floating and is provided with a connecting hole (not shown in the drawing) that is rotatably connected to the suspension link 211.

[0077] The present invention realizes the circulation transportation of the buoy in the vertical direction by providing the conveying bracket 1, maximizes the use of the storage space in the vertical direction, saves the available space of the offshore dock deck, does not need to provide a longer crane arm to grab and lift the wind turbine foundation module in a large range, reduces the volume and occupied space of the lifting equipment, reduces the lifting height of the foundation module assembly, and thus reduces the center of gravity height of the lifting equipment, reduces the influence of wind resistance on the foundation assembly process, avoids problems such as shaking, improves the stability of the equipment and expands the operational weather window; at the same time, it further saves the working energy consumption of the lifting equipment;

[0078] The advantage of vertical circulating conveying of fan buoys is that it avoids the buoy storage and grabbing restrictions of fixed module stacking racks in the existing technology, and can adjust the buoy conveying efficiency according to the assembly rhythm. It is fast, controllable, flexible and highly intelligent.

[0079] The present invention also provides a method for transporting a transport tool for a wind turbine foundation buoy, comprising the following steps:

[0080] Circular conveying step: the circulating driving mechanism 33 drives the sprocket 332 to rotate and drives the circulating chain 34 to move along the circulating guide rail 31, thereby driving the suspension assembly 21 and the placement plate 22 to circulate between the front bracket 11 and the rear bracket 12 through the connecting plate 32 on the circulating chain 34;

[0081] Lifting and docking step: After the buoy is delivered to its place, the placement plate 221 extends above the support frame 41; the lifting drive mechanism 42 drives the support frame 41 to rise, and the support bar 412 passes through the offset groove 2211 from bottom to top, lifting the buoy off the placement plate 221, and the placement plate 221 retracts to the placement plate 22 through the avoidance cavity 413, completing the docking of the buoys;

[0082] Horizontal transfer step: The supporting frame 41 and the buoy that have completed the jacking and docking are driven by the sliding plate 43 to slide along the transfer trough 51, and the buoy is transferred to the assembly station and lifted and assembled by the lifting equipment.

[0083] The pontoon transportation method of the present invention is simple to operate and has few steps. Since a vertical circulating conveying bracket 1 is provided with a placement component 2 with strong versatility, the difficulty of storing and conveying the pontoon is reduced, and the conveying steps are faster. Furthermore, since the transfer component 4 is provided with a support frame 41 that can be staggered and lifted and docked with the placement plate 221, after the pontoon is transported to its place, it is only necessary to lift the support frame 41 so that the support bar 412 passes through the staggered groove 2211 of the placement plate 221, and complete the staggered lifting and lowering of the support frame 41 and the placement plate 221, and the operation of transferring the pontoon to the support frame 41 is completed without redundant grasping steps, which is fast and stable. After the pontoon docking is completed, the support frame 41 can be transferred to the basic assembly station under the drive of the sliding plate 43, which greatly improves the pontoon transportation efficiency.

[0084] On the other hand, the docking of the placement plate 221 with the support frame 41 and the movement of the sliding plate 43 on the transfer trough 51 are all carried out at low altitude on the deck of the offshore dock, thereby further improving the assembly stability and reducing the wind resistance impact and safety hazards of high-altitude operations.

[0085] It should be noted that the present invention also includes other components or elements that meet the implementation conditions, such as a control system, a sensor system, etc.; the present invention does not elaborate on this.

For ordinary technicians in this field, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
