Description

Technical Field

[0001] This invention relates to the field of wind turbine generator technology, and in particular to a fully rotating single-blade multi-functional lifting device. Background Technology

[0002] The wind power industry is currently in a period of rapid growth, and wind power equipment is constantly developing towards higher power and taller towers. Wind farms are mostly located in areas with inconvenient transportation and harsh environments, such as high mountains, deserts, wilderness, nearshore areas, shallow seas, and offshore areas. This has led to increasingly higher requirements for the equipment used in the installation and maintenance of wind turbines, increasing the difficulty of operation, and significantly increasing hoisting costs.

[0003] Guided by the goal of maximizing power generation per unit cost, the increasing power output per unit unit and the increased swept area per kilowatt are irreversible trends in wind turbines. This has led to larger rotor diameters and higher hub centers. However, due to limitations imposed by lifting height, load, site conditions, and lifting window, the advantages of single-blade installation over traditional installation methods are becoming increasingly apparent.

[0004] Currently, wind farms still commonly use large equipment with high lifting capacity and high lifting height, such as crawler cranes, all-terrain cranes, offshore crane vessels, or self-elevating work platforms, for turbine installation. This constitutes an overuse of resources. The purchase or rental costs of these large equipment are high. If a single-blade installation method were used, there would be significant advantages in terms of lifting equipment, site requirements, wind speed, and lifting window. In the context of fierce competition in the wind power industry and increasingly shorter construction cycles, reducing construction costs will greatly promote the long-term development of my country's wind power industry.

Please refer to [link / reference]. Figures 1 to 9As shown, a preferred embodiment is illustrated, illustrating a fully rotating single-blade multi-functional lifting device, including a balancing mechanism 1, a lateral rocking mechanism 2, a longitudinal rotation mechanism 3, an upper clamping mechanism 4, a lower clamping mechanism 5, a cable wind mechanism 6, a lateral rocker arm 7, a main rotating beam 8, a C-beam 9, a lateral adjustment mechanism 10, and a turntable module 11. One end of the lateral rocker arm 7 is connected to the balancing mechanism 1, and the other end is connected to the cable wind mechanism 6. The main rotating beam 8 is located on one side of the cable wind mechanism 6, and the turntable module 11 and the lateral rocking mechanism 2 are located on the other side of the cable wind mechanism 6. One end of the lateral rocking mechanism 2 is connected to one side of the lateral rocker arm 7. The other end of the rocking mechanism 2 is connected to the turntable module 11. The main rotating beam 8 is connected to the other side of the rocker arm 7. Two C-shaped beams 9 are provided at both ends of the main rotating beam 8. An upper clamping mechanism 4 is provided on the upper inner wall of each C-shaped beam 9, and a lower clamping mechanism 5 is provided on the lower inner wall of each C-shaped beam 9. Each upper clamping mechanism 4 is directly opposite to the lower clamping mechanism 5. The other end of the rocker arm 7 is also provided with a longitudinal rotating mechanism 3, which is used to drive the main rotating beam 8 to rotate. The lateral adjustment mechanism 10 is located at the lower end of the rocker arm 7 and is connected to the two C-shaped beams 9 and the two upper clamping mechanisms 4. In this embodiment, the balancing mechanism 1 ensures the overall attitude monitoring of the fully rotating single-blade multi-functional lifting device. The lateral rocker arm 7 cooperates with various mechanisms to bear the entire weight of the lifting device and the blade. The lateral rocker mechanism 2 is used to adjust the lateral angle of the lifting device. The longitudinal rotation mechanism 3 is used to adjust the longitudinal rotation angle of the lifting device. The upper clamping mechanism 4 cooperates with the lower clamping mechanism 5 to clamp and fix the wind turbine blade and move together. The cable wind mechanism 6 is controlled by the fully rotating single-blade multi-functional lifting device to maintain a constant tension force during the lifting of the blade, so that the lifting device moves smoothly in the air. The rotating main beam 8 is connected to the C-shaped beam 9 to realize the longitudinal rotation function. In this embodiment, during use, the blade can be clamped by the upper clamping mechanism 4 and the lower clamping mechanism 5, and then the blade is hoisted to a certain height. Then, the lateral rocker arm 7 is controlled to swing by the lateral rocker mechanism 2 to adjust the lateral rocker angle.

The auxiliary cylinder 123 is controlled by the cylinder controller 124 and the pressure sensor 125 to drive the first sliding wedge block 122 and the second sliding wedge block 126 to slide within the limiting block 129. Combined with the wedge grooves 405 on both sides of the first clamping cylinder 401, the first clamping cylinder 401 is finally locked and fixed. In this embodiment, the pressure sensor 125 indirectly measures the clamping force acting on the first clamping cylinder 401 by measuring the oil pressure inside the hydraulic cylinder of the auxiliary cylinder 123. Figure 7 As shown, the first sliding wedge 122 and the second sliding wedge 126 are located on both sides of the lower end of the cylinder fixing tooth plate 121. During use, when the clamping force of the first sliding wedge 122 and the second sliding wedge 126 on the first clamping cylinder 401 is insufficient, the pressure sensor 125 can monitor the pressure of the first sliding wedge 122 and the second sliding wedge 126. After receiving the detected pressure signal value, the cylinder controller 124 controls the auxiliary cylinder 123 to drive the first sliding wedge 122 and the second sliding wedge 126 into the wedge groove 405, thereby fixing the first clamping cylinder 401.
