Description

Technical Field

[0001] The present invention relates to the technical field of offshore wind power generation, and in particular to a vertical rapid assembly device and method for an offshore wind power conductor frame. Background Art

[0002] Offshore wind power has experienced rapid growth in recent years. With larger turbine capacities and taller hub heights, the importance of jackets, the supporting structure for these large wind turbines, has become even more pronounced. As the water depths in which jackets are used deepen, jacket sizes are increasing, leading to numerous challenges in fabrication and assembly, including low efficiency, high costs, and significant risks.

[0003] Currently, jacket assembly methods typically involve traditional horizontal and vertical assembly. Traditional horizontal assembly involves assembling and welding the jacket in sections horizontally on the ground, then using large lifting equipment to flip it upright. However, this method requires a large footprint and carries high risks associated with lifting. Traditional vertical assembly involves assembling and welding the jacket from the bottom to the top, assembling from bottom to top. This method requires scaffolding, which increases in height as the jacket is assembled. This creates significant safety risks, inconveniences during construction, and difficulty maintaining vertical accuracy between sections.

[0004] Therefore, it is necessary to propose a vertical rapid assembly device and method for offshore wind power conductor frames to solve the above problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that, in view of the current method of assembling jackets, the traditional horizontal assembly occupies a large area and has a high risk of turning over and lifting, while the traditional vertical assembly requires the erection of scaffolding, and the height of the scaffolding gradually increases with the assembly of the jacket, personnel working at high altitude, there are great safety hazards, construction is inconvenient, and the vertical accuracy between sections is difficult to ensure. Therefore, a vertical rapid assembly device and method for offshore wind power jackets are proposed.

[0006] To achieve the above-mentioned purpose, the present invention proposes a vertical rapid assembly device for an offshore wind power conductor frame, comprising: four supporting legs, a rectangular frame, two lifting main beams, a first oil cylinder sliding mechanism and four lifting mechanisms. The tops of the four supporting legs are respectively welded to the four corners of the rectangular frame, and the two ends of the two lifting main beams are mounted on the rectangular frame and arranged in parallel. Four first oil cylinder sliding mechanisms are symmetrically arranged on the rectangular frame. The two ends of each lifting main beam are respectively connected to a first oil cylinder sliding mechanism, and are driven by the first oil cylinder sliding mechanism to slide longitudinally on the rectangular frame. Two lifting mechanisms are installed at intervals on each lifting main beam.

[0007] Among them, the four supporting legs are all lattice structures.

[0008] Among them, the rectangular frame structure includes two longitudinal beams and two transverse beams arranged in parallel. The two transverse beams are spaced and connected on the inner side walls of the two longitudinal beams. The two ends of the two lifting main beams are respectively mounted on the two longitudinal beams. The first cylinder sliding mechanism is composed of a first fixed connecting seat, a first cylinder and a first movable connecting seat connected in sequence. The four first fixed connecting seats are respectively fixedly installed on the upper surfaces of the two longitudinal beams. The four first movable connecting seats are respectively connected to the two ends of the two lifting main beams. The two lifting main beams slide longitudinally on the top of the longitudinal beams by the drive of the first cylinder sliding mechanism.

[0009] Among them, the lifting mechanism includes a movable pulley group, a fixed pulley group and a second oil cylinder sliding mechanism. The second oil cylinder sliding mechanism is composed of a second fixed connecting seat, a second oil cylinder and a second movable connecting seat connected in sequence. The second fixed connecting seat is fixedly installed on the upper surface of the lifting main beam. The second movable connecting seat is connected to the fixed pulley group. The second oil cylinder sliding mechanism drives the fixed pulley group to slide laterally on the upper surface of the lifting main beam. The fixed pulley group and the movable pulley group are connected by steel wire ropes wound at a designed ratio. The movable pulley group is suspended below the rectangular frame. A hook is fixed at the bottom thereof. The steel wire rope is connected to the winch. The lifting and lowering of the movable pulley group is controlled by the winch. The winch is fixed on the ground on one side below the corresponding controlled movable pulley group.

[0010] Among them, the vertical rapid assembly equipment for offshore wind power conductor racks further includes a module vehicle for transporting conductor rack components to the lifting point position on the ground at the bottom of the rectangular frame.

[0011] To achieve the above-mentioned object, the present invention further proposes a method for vertical rapid assembly of an offshore wind power conductor frame, comprising the following steps:

[0012] Step 1: Set up the vertical rapid assembly equipment for offshore wind power conductor racks at the target location;

[0013] Step 2: Divide the wind turbine conduit rack into four sections in the workshop: top platform, upper bracket, middle bracket, lower bracket and column legs;

[0014] Step 3: The module vehicle first transports the top platform segment to the bottom of the lifting point of the built vertical rapid assembly equipment. The hooks on the movable pulleys of the four lifting mechanisms are connected to the lifting ears on the four directions of the top platform segment. The top platform segment is lifted to the elevation position. The module vehicle then transports the upper bracket segment to the bottom of the lifting point of the vertical rapid assembly equipment and positions it. The lifting mechanism lowers the top platform segment to accurately align it with the upper bracket segment and connects it securely. The lifting mechanism lifts the top platform segment and the upper bracket segment, and the module vehicle drives away.

[0015] Step 4: The lifting mechanism hoists the assembled top platform segment and upper bracket segment to the elevation position as a whole. The module vehicle transfers the middle bracket segment to the bottom of the vertical rapid assembly equipment lifting point and positions it. The lifting mechanism lowers the assembled top platform segment and upper bracket segment to accurately align the upper bracket segment with the middle bracket segment and connect them securely. Then the lifting mechanism lifts the assembled top platform segment, upper bracket segment and middle bracket segment, and the module vehicle drives away.

[0016] Step 5: The hoisting mechanism hoists the assembled top platform segment, upper support segment and middle support segment to the elevation position. The module vehicle transports the lower support segment and column leg segment to the bottom of the vertical rapid assembly equipment lifting point and positions them. The hoisting mechanism lowers the assembled top platform segment, upper support segment and middle support segment, so that the middle support segment is accurately aligned with the lower support segment and column leg segment and connected securely. The lifting device lifts the four assembled jacket segments, and the module vehicle drives away.

[0017] Step 6: The four sections of the jacket are assembled vertically and transported to the storage site by the module vehicle. At this time, the vertical rapid assembly equipment can proceed to the next jacket assembly construction.

[0018] Among them, in step three, the module vehicle transfers the top platform segment from the segment input side of the vertical rapid assembly equipment to the bottom of the lifting point of the vertical rapid assembly equipment, the movable pulley group of the lifting mechanism is connected to the top platform segment and lifted to the set elevation position, and the module vehicle drives away; then, the module vehicle transfers the upper bracket segment from the segment input side to the predetermined position at the lower end of the top platform segment, and the first cylinder sliding mechanism and the second cylinder sliding mechanism cooperate with the longitudinal and transverse movement to make the top platform segment and the upper bracket segment accurately aligned to achieve assembly accuracy, and then start positioning welding until the connection is firm, and the lifting mechanism lifts the two assembled jacket segments to the elevation position, and then the module vehicle drives away.

[0019] In step 4, the module vehicle transports the middle bracket segment from the segment input side to the predetermined position at the lower end of the two assembled jacket segments. The two assembled jacket segments are precisely aligned with the middle bracket segment to achieve assembly accuracy. Then, positioning welding is started until the connection is secure. The lifting mechanism then lifts the three assembled jacket segments to the elevated position, and the module vehicle drives away.

[0020] In step five, the module vehicle transports the lower bracket and column leg segment from the segment input side to the predetermined position at the lower end of the three assembled jacket segments. The three assembled jacket segments are precisely aligned with the lower bracket and column leg segment to achieve assembly accuracy, and then positioning welding is started until the connection is firm. At this point, the jacket has been assembled as a whole.

[0021] In step six, after the four sections of the jacket are vertically assembled, the movable pulley block and the lifting lugs of the upper platform section are disassembled, and the module vehicle transports the assembled jacket out from the assembly output side.

[0022] The technical solution of the present invention has the following beneficial effects compared with traditional horizontal assembly and vertical assembly:

[0023] (1) High assembly precision: The present invention adopts the method of vertical lifting and assembly of the jacket in sections, relying on the weight of the structure to maintain the plumb bob, thus ensuring the verticality and overall linearity of the jacket;

[0024] (2) High production efficiency: The present invention adopts the assembly sequence from the top segment to the bottom segment, the construction surface of the interface is low, the segments only need to be accurately positioned and firmly connected, and after all the segments are assembled, they are transported to the storage site by the module vehicle to complete the welding work, which shortens the operation time and has high production efficiency;

[0025] (3) Good economic benefits: The construction method of the present invention does not require the erection of scaffolding, the construction operation occupies a small area, the assembly period is short, the site utilization efficiency is high, and the economic benefits are good.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0042] The vertical rapid assembly equipment for offshore wind power conductor frames comprises: four supporting legs 1, a rectangular frame 2, two hoisting main beams 3, a first oil cylinder sliding mechanism 4 and four lifting mechanisms 5.

[0043] Each of the four support legs 1 is a lattice structure, with connecting beams 6 installed between the two support legs 1 on three sides. The tops of the four support legs 1 are welded to the four corners of the rectangular frame 2. The two ends of the two lifting beams 3 are mounted on the rectangular frame 2 and arranged in parallel. Four first hydraulic cylinder sliding mechanisms 4 are symmetrically arranged on the rectangular frame 2. Each lifting beam 3 is connected to a first hydraulic cylinder sliding mechanism 4 at each end, and is driven by the first hydraulic cylinder sliding mechanism 4 to slide longitudinally on the rectangular frame 2. Two lifting mechanisms 5 are installed on each lifting beam 3 at intervals.

[0044] In this embodiment, the rectangular frame 2 structure includes two longitudinal beams 7 and two transverse beams 8 arranged in parallel. The two transverse beams 8 are spaced apart and connected to each other on the inner side walls of the two longitudinal beams 7, and their upper surfaces are no higher than the upper surfaces of the two longitudinal beams 7. The two ends of the two lifting beams 3 are respectively mounted on the two longitudinal beams 7. The first cylinder sliding mechanism 4 is composed of a first fixed connection seat, a first cylinder, and a first movable connection seat connected in sequence. The four first fixed connection seats are respectively fixedly installed on the two ends of the upper surfaces of the two longitudinal beams 7. The four first movable connection seats are respectively connected to the two ends of the two lifting beams 3. The two lifting beams 3 are driven by the first cylinder sliding mechanism 4 to slide longitudinally on the top of the two longitudinal beams 7.

[0045] The lifting mechanism includes a movable pulley block 9, a fixed pulley block 10, and a second hydraulic cylinder sliding mechanism 11. The second hydraulic cylinder sliding mechanism 11 is composed of a second fixed connector, a second hydraulic cylinder, and a second movable connector. The second fixed connector is fixedly mounted on the upper surface of the lifting beam 3. The second movable connector is connected to the fixed pulley block 10. The second hydraulic cylinder sliding mechanism 11 can drive the fixed pulley block 10 to slide laterally on the upper surface of the lifting beam 3. Generally speaking, the fixed connectors of two second hydraulic cylinder sliding mechanisms on the same lifting beam 3 are 10-12 meters apart. The fixed pulley block 10 and the movable pulley block 9 are connected by a steel wire rope 12 wound at a designed ratio. The movable pulley block 9 is suspended below the rectangular frame 2. A hook 13 is fixed to its bottom. The steel wire rope 12 is connected to a winch 14, which controls the raising and lowering of the movable pulley block 9. The winch 14 is fixed to the ground below the corresponding movable pulley block 9.

[0046] This vertical rapid assembly equipment for offshore wind turbine jackets also includes a modular vehicle for transporting jacket components to the lifting points located on the ground below the rectangular frame 2. In other embodiments, a total station or laser plummet may also be included to monitor each jacket segment's plumb bob, maintained by the jacket's own weight, for real-time monitoring to ensure the jacket's verticality and overall alignment.

[0047] A method for vertical rapid assembly of an offshore wind power conductor frame comprises the following steps:

[0048] Step 1: Select the target site in the open space, and then build the vertical rapid assembly equipment for offshore wind power conductor racks.

[0049] Step 2: Divide the wind turbine conduit rack into four sections in the workshop: top platform, upper bracket, middle bracket, lower bracket and column legs.

[0050] Four segments are typical segment forms of the jacket, and the remaining segment forms are also applicable to the vertical rapid assembly equipment and method of the present invention. The working surface is deployed in the workshop to meet the factory's standardized manufacturing process and avoid various impacts caused by open-air operations.

[0051] Step 3: The module vehicle first transports the top platform segment to the bottom of the lifting point of the built vertical rapid assembly equipment. The hooks on the movable pulley groups of the four lifting mechanisms are connected to the lifting ears on the four directions of the top platform segment. The top platform segment is lifted to the elevation position. The module vehicle then transports the upper bracket segment to the bottom of the lifting point of the vertical rapid assembly equipment and positions it. The lifting mechanism lowers the top platform segment and accurately aligns it with the upper bracket segment and connects it securely. The lifting mechanism lifts the top platform segment and the upper bracket segment, and the module vehicle drives away.

[0052] Specifically, the module car transfers the top platform segment from the segment input side of the vertical rapid assembly equipment to the bottom of the vertical rapid assembly equipment lifting point. The movable pulley block of the lifting mechanism is connected to the top platform segment and lifted to the set elevation position. The module car then drives away. Figure 8 , Figure 8 Schematic diagram of lifting the top platform segment.

[0053] Next, the module vehicle transports the upper support segment from the segment input side to the predetermined position at the lower end of the top platform segment. The first and second cylinder sliding mechanisms cooperate with each other to move longitudinally and transversely, so that the top platform segment and the upper support segment are precisely aligned to achieve assembly accuracy. Then, positioning welding is started until the connection is firm. After the lifting mechanism lifts the two assembled jacket segments to the elevated position, the module vehicle drives away. Figure 9 , Figure 9 Schematic diagram of the assembly of the top platform segment and the upper bracket segment.

[0054] Step 4: The lifting mechanism lifts the assembled top platform segment and upper bracket segment as a whole to the elevated position. The module vehicle transfers the middle bracket segment to the bottom of the vertical rapid assembly equipment lifting point and positions it. The lifting mechanism lowers the assembled top platform segment and upper bracket segment to accurately align the upper bracket segment with the middle bracket segment and connect them securely. Then the lifting mechanism lifts the assembled top platform segment, upper bracket segment and middle bracket segment, and the module vehicle drives away.

[0055] Specifically, the module vehicle transports the middle section support segment from the segment input side to the predetermined position at the lower end of the two assembled jacket segments. The two assembled jacket segments are precisely aligned with the middle section support segment to achieve assembly accuracy. Then, positioning welding is started until the connection is secure. The lifting mechanism then lifts the three assembled jacket segments to the elevated position, and the module vehicle drives away. Figure 10 , Figure 10 This is a schematic diagram of the assembly of the top platform segment, upper bracket segment and middle bracket segment.

[0056] Step 5: The lifting mechanism hoists the assembled top platform segment, upper bracket segment and middle bracket segment to the elevation position. The module vehicle transports the lower bracket and column leg segment to the bottom of the vertical rapid assembly equipment lifting point and positions them. The lifting mechanism lowers the assembled top platform segment, upper bracket segment and middle bracket segment, so that the middle bracket segment is accurately aligned with the lower bracket and column leg segment and connected securely. The lifting device lifts the four assembled jacket segments and the module vehicle drives away.

[0057] Specifically, the module vehicle transports the lower bracket and column leg segments from the segment input side to the predetermined position at the lower end of the three assembled jacket segments. The three assembled jacket segments are precisely aligned with the lower bracket and column leg segments to achieve assembly accuracy. Then, positioning welding is started until the connection is firm. At this point, the jacket is completely assembled. Figure 11 , Figure 11 This is a schematic diagram of the assembly of the top platform segment, upper bracket segment, middle bracket segment, lower bracket segment and column leg segment.

[0058] Step 6: The four sections of the jacket are assembled vertically and transported to the storage site by the module vehicle. At this time, the vertical rapid assembly equipment can proceed to the next jacket assembly construction.

[0059] Specifically, after the four sections of the jacket are assembled vertically, the hook 13 of the movable pulley block and the lifting lug of the upper platform section are disassembled, and the module vehicle transports the assembled jacket out from the assembly output side. Figure 12 , Figure 12 This is the main view after the catheter rack is assembled.

[0060] For the determination of the output and input sides of this vertical rapid assembly equipment for offshore wind power conductor frames, please refer to Figure 3 and Figure 4 The output side is the side without connecting beams between the two supporting legs. It is an open door structure used for the overall transfer of the jacket. The other side corresponding to the output side is the input side. It is a semi-open door structure. The jacket is transported to the designated location in sections by modular vehicles.

[0061] This equipment and method for the vertical rapid assembly of offshore wind turbine jackets utilizes segmented vertical lifting, assembling the jackets sequentially from the top segment to the bottom segment. The segments are lifted vertically, relying on the weight of the structure to maintain a plumb bob position. Construction workers work at a low surface, resulting in high assembly precision, high production efficiency, and good economic benefits. A modular vehicle transports each jacket segment to a ground sample location below the lifting point of the vertical rapid assembly equipment. The vertical rapid assembly equipment's lifting device lifts the jacket segment to an elevated position. The modular vehicle transports the next jacket segment to the ground sample location. After precisely aligning and securely connecting it to the lifted segment, the entire jacket segment is lifted vertically again. Once the next jacket segment arrives on site, it can be quickly transported to a storage site for welding, and then the next jacket segment can be assembled. This entire assembly method is simple, safe, and effective.

[0062] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
