Hoisting device with multi-point balance control for offshore wind turbine installation

Abstract

The invention discloses a multi-point balance control hoisting device for offshore wind turbine installation, and belongs to the field of offshore wind turbine installing.The multi-point balance control hoisting device for offshore wind turbine installation comprises a hoisting equipment body, a lifting hook is connected to the lower end of the hoisting equipment body, and a balance controller is connected to the lower end of the lifting hook; the lower end of the balance controller is fixedly connected with a multi-cavity regulation and control cylinder, the lower end of the multi-cavity regulation and control cylinder is fixedly connected with a multi-cavity balance cylinder, and through cooperation of the hydraulic fine adjustment assembly and the balance control assembly, after the gravity lifting rope is tightened and limited by the gravity of the fan blade, the dragging length of the gravity lifting rope can be adjusted; according to the fan blade lifting device, the multi-point holding sleeves are arranged, so that the mounting position of the fan blade is effectively regulated, the control precision of the lifting device body is effectively improved, the gravity balance of the fan blade is effectively controlled in a multi-point connection mode under the cooperation of the multi-point holding sleeves, and the trafficability and the mounting convenience of the fan blade are improved.

Description

technical field [0001] The invention relates to the field of installation of offshore wind turbines, and more specifically relates to a hoisting device with multi-point balance control for installation of offshore wind turbines. Background technique [0002] Wind power is the fastest growing green energy technology in the world. While the construction of onshore wind farms is developing rapidly, people have noticed some restrictions on the utilization of onshore wind energy, such as large land occupation and noise pollution. Due to the abundant wind energy resources at sea and the feasibility of today's technology, the sea will become a rapidly developing wind power market. With the development of offshore wind farm technology, wind power will surely become an important source of energy for the sustainable development of my country's eastern coastal areas. [0003] Offshore wind turbines, referred to as offshore wind turbines, are electrical equipment that convert wind energ...

AI Technical Summary

Problems solved by technology

[0004] Offshore wind turbines are mainly transported by the offshore wind power installation ship and installed by the lifting equipment on the ship. When using the lifting equipment to lift the blades, since the blades and the rotor need to be connected and installed to complete the wind drive, it is necessary to ensure the flange threaded holes during hoisting. The adjustment angle is aligned with the bolts to ensure the effectiveness of the installation. However, in the prior art, the control accuracy of the blade position adjustment during hoisting is low, and the control is difficult, which is not conducive to fine-tuning the blade installation position. thus reducing the construction efficiency
