Hoisting device and hoisting method

Abstract

The invention provides a hoisting device and a hoisting method. The hoisting device is used for integrally hoisting a cabin and a generator of a direct-drive wind turbine, wherein the cabin and the generator are assembled together. The hoisting device contains a T-shaped hoisting beam which has a first end and a second end and a third end which are disposed opposite to each other; a first rigging group which is connected to the first end of the T-shaped hoisting beam; and a second rigging group which is connected to the second end and the third end of the T-shaped hoisting beam, wherein the first rigging group is connected to eachhangerof the cabin and the second rigging group is connected to each hanger of the generator. Therefore, the hoisting device can integrally hoist the cabin and the generator of the direct-drive wind turbine, wherein the cabin and the generator are assembled together.

Description

technical field [0001] The invention relates to the field of hoisting equipment, and more specifically, the invention relates to a hoisting equipment and a hoisting method capable of integrally hoisting a direct-drive wind turbine's assembled nacelle and generator. Background technique [0002] A wind turbine is a device that converts the kinetic energy of wind into other forms of energy. A wind turbine has an impeller that converts the kinetic energy of the wind into mechanical energy. The converted mechanical energy can be further converted into electrical energy through a generator, or can be directly used to drive the operation of various mechanical equipment. Such a wind turbine including a generator is also called a wind generator. [0003] Wind turbines can be applied to offshore wind farms and onshore wind farms. Large-scale offshore wind turbines are installed in the marine environment, and they need to rely on equipment such as large hoisting ships and barges fo...

AI Technical Summary

Problems solved by technology

[0004] Among the two hoisting schemes of the existing direct-drive wind turbine nacelle and generator, the first hoisting scheme carries out overall hoisting after assembling all components. The requirements are high, the project construction cost is high, and it is difficult for large-scale floating cranes to enter the coastal intertidal zone, so this hoisting scheme has many limitations; the second hoisting scheme transports each component independently to the offshore installation site for installation. Hoisting, so this hoisting scheme requires multiple hoisting parts, which increases the time and cost of on-site construction. Due to the limitation of the time window of offshore construction, this method is not suitable for large-scale offshore wind farm construction operations
