Wind turbine multifunctional platform and blade disassembly method

Abstract

The invention relates to a multifunctional platform of a wind turbine and a vane dismantling method. The multifunction platform comprises a platform frame, a winch mechanism, a plurality of tower barrel clamping mechanism, a mobile trolley and two vane adjusting supports and two groups of vane dragging mechanisms, wherein the platform frame comprises a base with an annular central hole, and two mutually parallel support arms; the winch mechanism is used for realizing up and down translation of a platform; the plurality of tower barrel clamping mechanism are annularly fixed on the periphery ofthe annular central hole of the platform and used for preventing the platform frame from rotating; the mobile trolley slides on the two support arms; and the two vane adjusting supports and the two groups of vane dragging mechanisms are used for dragging vanes to adjust the vanes to an appropriate height and angle. According to the method for vane dismantling by utilizing the multifunctional platform, the multifunctional platform is lift to the appropriate height of a tower barrel by utilizing the winch mechanism, working personnel are conveyed to all hoist point positions of the vane by the mobile trolley and tied up with straps, and the vane is dismantled and stably descends to a transport ship by utilizing a crane ship, a fan maintenance crane and the vane dragging mechanism.

Description

technical field [0001] The invention relates to a blade maintenance platform of an offshore wind turbine, and also relates to a blade replacement method of an offshore wind turbine. Background technique [0002] For the sustainable development of human beings, environmental protection, low-carbon economy, energy conservation and emission reduction, clean energy has become an important direction of economic development. As an important part of clean energy, wind power is developing rapidly. In recent years, the number of wind farms in various places has continued to increase. While onshore wind farms have continued to develop, offshore wind farms have also begun to be constructed. At the same time, with the development of wind power technology and the gradual improvement and improvement of unit performance, wind turbines are becoming more and more economical and efficient, and the capacity of a single unit is also increasing. [0003] However, with the gradual increase of t...
