Abstract
Description
Technical Field
[0001] This invention relates to the field of wind turbine jacket assembly technology, specifically a high-efficiency assembly device and method for wind turbine jacket TKY nodes. Background Technology
[0002] With the depletion of onshore and nearshore wind energy resources, deep-sea wind energy has become the main battleground for wind power generation. Furthermore, as the grid-connected electricity price for new energy transitions from grid parity to market-based pricing, continuously reducing construction costs has become a survival strategy for power generation companies. Therefore, the trend towards larger wind turbine units has become the mainstream in wind power. The development of offshore wind power into deeper and larger-scale systems presents unprecedented challenges. For example, the deep-sea environment leads to more complex operating conditions for wind turbines, placing higher demands on the reliability and fatigue resistance of the entire turbine foundation. The wind turbine jacket foundation is a truss structure composed of multiple welded cylindrical sections, containing multiple TKY nodes, which are fatigue nodes of the wind turbine foundation.
[0003] High-precision assembly and high-quality welding of TKY nodes are the challenges in the manufacturing process of jacket foundations. During the service life of jacket foundations, the two key factors affecting their fatigue life are welding quality and assembly accuracy. Low assembly accuracy can lead to misalignment between adjacent sections, which reduces the fatigue life of the jacket foundation. Currently, the assembly of jacket foundations relies heavily on manual labor, and the assembly accuracy depends on the skill level of the workers. Therefore, it is difficult to achieve high-precision control of the assembly accuracy of jacket foundations. Summary of the Invention
[0004] In view of this, the present invention addresses the shortcomings of the prior art by providing a high-efficiency assembly device and method for TKY nodes of wind power jacket foundations, which can improve the assembly accuracy of TKY nodes of jacket foundations and improve the manufacturing efficiency of jacket foundations.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a high-efficiency assembly device for wind turbine jacket TKY node, including a gantry-type support for supporting the main TKY node pipe, assembly frames for installing TKY node branch pipes arranged on both sides of the gantry-type support, and a track system fixed to the foundation. The gantry-type support spans across the track system, and the two assembly frames are slidably arranged on the track system. The assembly frame includes a movable support, a lifting support, and an inclined support. The lifting support is set on the top of the movable support, and one side of the top of the lifting support is hinged to the inclined support. A jack is set on the lifting support, and the upper end of the jack is hinged to the bottom surface of the inclined support.
[0006] Furthermore, there are two gantry-type supports, which are respectively supported at both ends of the TKY node main pipe, and an arc-shaped support frame is set on the top of the gantry-type supports.
[0007] Furthermore, the track system includes two slide rails, each with four sliders slidably mounted on it.
[0008] Furthermore, the movable support includes a support body, railings, ladders, and a base plate. Railings are provided at the top edge of the support body, ladders are provided on the sides of the support body, and base plates are provided at the bottom of the four legs of the support body. The base plates are connected to the sliders.
[0009] Furthermore, the top surface of the arc-shaped support frame is arc-shaped, and a slot is provided on the arc-shaped surface. Multiple rollers are installed inside the slot, and the upper parts of the multiple rollers extend out from the slot.
[0010] Another objective of this invention is to provide a high-efficiency assembly method for TKY nodes of wind turbine jacket structures, based on the aforementioned high-efficiency assembly device for TKY nodes of wind turbine jacket structures, comprising the following steps: S1. The hydraulic module vehicle transports the TKY node main pipe to the TKY node assembly area via a gantry-type support. After the hydraulic module vehicle leaves, the circumferential angle of the TKY node main pipe is adjusted. The position of the positioning baseline is checked by a total station to ensure that it meets the requirements of the drawing. S2. Place TKY node branch pipes on the inclined supports of the two assembly frames respectively, adjust the circumferential angle of the TKY node branch pipes, and use a total station to check to ensure that the position of the positioning baseline of the TKY node branch pipes meets the requirements of the drawings. Adjust the TKY node branch pipes on both sides symmetrically and synchronously. S3. The moving supports of the two assembly frames move towards each other along the track system, driving the two TKY node branch pipes to move towards the TKY node main pipe. The TKY node main pipe and TKY node branch pipes are connected. The positioning baselines of the TKY node main pipe and TKY node branch pipes are aligned. The relative positions of the TKY node main pipe and TKY node branch pipes are checked using a total station. During the connection process, the angle of the TKY node branch pipe relative to the TKY node main pipe is adjusted by jacks. S4. After adjusting the TKY node to meet the dimensions required in the drawing, carry out the positioning welding between the main pipe of the TKY node and the branch pipe of the TKY node. After the S5, TKY node main pipe and TKY node branch pipe are firmly welded, the two assemblies move away from each other, and the gantry support is transported to the TKY node welding area by a hydraulic modular vehicle to carry out the TKY node welding work.
[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention proposes a high-efficiency assembly device and method for TKY nodes of offshore wind turbine jacket foundations. By using a gantry-type support to support and transport the main TKY node pipe, and using two assembly frames to move two TKY node branch pipes towards the main TKY node pipe, the angle of the TKY node branch pipes is adjusted by jacks and then connected to the main TKY node pipe. This achieves modular fabrication of TKY nodes for offshore wind turbine jacket foundations, significantly improving the manufacturing efficiency of jacket foundations. The application of the TKY node assembly device not only improves the manufacturing quality of TKY nodes for jacket foundations, but also reduces the hoisting risks during the jacket assembly process, reduces the labor intensity of workers, and provides strong support for technological progress in the industry.

The gantry-type support 2 spans across the track system 6, and the two assembly frames are slidably arranged on the track system 6. The assembly frame includes a movable support 3, a lifting support 4, and an inclined support 5. The lifting support 4 is provided on the top of the movable support 3. One side of the top of the lifting support 4 is hinged to the inclined support 5. A jack 8 is provided on the lifting support 4. The upper end of the jack 8 is hinged to the bottom surface of the inclined support 5.
[0015] Specifically, there are two gantry brackets 2, which are respectively supported at both ends of the TKY node main pipe 101, and an arc-shaped support frame is set on the top of the gantry brackets 2.
[0016] The movable support 3 and the lifting support 4 are fixedly connected by bolts, and the two remain relatively stationary during the movement.
[0017] The top platform of the lifting bracket 4 has a hinged sleeve 401 welded to its side for connecting the inclined bracket 5. The top platform of the lifting bracket 4 has round holes and multiple threaded holes for fixing the jack 8. The bottom connecting plate 402 of the lifting bracket 4 is connected to the movable bracket 3 by bolts.
[0018] The inclined support 5 has a hinged sleeve 501 welded to its side. The hinged sleeve 501 of the inclined support 5 and the hinged sleeve 401 of the lifting support 4 are connected by a pin 7. During operation, under the action of the jack 8, the inclined support 5 can rotate around the pin 7.
[0019] The track system 6 includes two slide rails 602, each with four sliders 601 slidably mounted on it. Both slide rails 602 have a break in the middle to allow the hydraulic module vehicle to pass through.
[0020] The mobile support 3 includes a support body 301, railings 302, ladders 303, and a base plate 304. The support body 301 is welded from structural steel, and a patterned steel plate platform is located on top of it to provide operating space for the operator. Railings 302 are installed at the top edge of the support body 301 to prevent workers from falling. Ladders 303 are welded to the sides of the support body 301 to allow the operator to go up and down the platform of the mobile support 3. The bottom of each of the four legs of the support body 301 is provided with a base plate 304, which is bolted to the slider 601 of the track system 6.
[0021] The top surface of the arc-shaped support frame is arc-shaped, and a slot is provided on the arc surface. Multiple rollers are installed inside the slot, and the upper parts of the multiple rollers extend out from the slot and contact the lower part of the TKY node main pipe, which facilitates the adjustment of the circumferential angle of the TKY node main pipe.
[0022] The assembly method of the high-efficiency assembly device for wind turbine jacket TKY node according to an embodiment of the present invention includes the following steps: Step (1): The hydraulic module vehicle transports the TKY node main pipe 101 to the TKY node assembly area through the gantry bracket 2. The hydraulic module vehicle drives away and adjusts the circumferential angle of the TKY node main pipe 101. The total station is used to check and ensure that the position of the positioning baseline A of the TKY node main pipe 101 meets the requirements of the drawing. At this time, the two assembly frames are in a separated state. Step (2): Place TKY node branch pipe 102 on the inclined support 5 of the two assembly frames respectively, adjust the circumferential angle of TKY node branch pipe 102, and use a total station to check to ensure that the position of the positioning baseline B of TKY node branch pipe 102 meets the requirements of the drawing.

Step (3): The moving support 3 of the two assembly frames moves towards each other along the track system 6, driving the two TKY node branch pipes 102 to move towards the TKY node main pipe 101. The TKY node main pipe and TKY node branch pipe are connected. The positioning reference lines of the TKY node main pipe 101 and TKY node branch pipe 102 are aligned. The relative positions of the TKY node main pipe 101 and TKY node branch pipe 102 are checked using a total station. During the connection process, the angle of the TKY node branch pipe 102 relative to the TKY node main pipe 101 is adjusted by the jack 8. Step (4): After adjusting the TKY node to meet the size requirements of the drawing, carry out the positioning welding between the main pipe 101 of the TKY node and the branch pipe 102 of the TKY node. The positioning welding must be carried out in strict accordance with the welding method and welding parameters of the welding process qualification. Step (5): After the TKY node main pipe 101 and TKY node branch pipe 102 are firmly welded, the two assembly frames move away from each other. The gantry bracket 2 is transported to the TKY node welding area by a hydraulic module vehicle to carry out the TKY node welding work.
[0023] Through the above steps (1)-(5), the assembly of a set of TKY node 1 was completed.
[0024] During the assembly of TKY node 1, assembly baselines are pre-marked on the TKY node main pipe 101 and TKY node branch pipe 102, enabling rapid positioning of the TKY node main pipe 101 and TKY node branch pipe 102, saving adjustment time. The assembly device of this invention allows for rapid assembly of TKY node 1, reducing the frequency of use of hoisting equipment, lowering installation costs, and reducing hoisting risks. During installation, the circumferential angle of branch pipe 102 can be finely adjusted using jacks 8. The equipment is simple and reliable. This invention enables modular fabrication of the jacket support TKY node 1, improving the accuracy and efficiency of jacket support fabrication and reducing manufacturing costs.
