Problems solved by technology
[0006] The present invention is to provide a hoisting method for key components of offshore wind turbines, which is used to realize the replacement of key components of the unit with only ordinary tugboats without the help of large-scale professional wind power installation ships, and to solve the problem of offshore wind power with a combination of a small number of tools and equipment. It is difficult to hoist the key parts (large parts) of the wind turbine unit, hoisting requires a special wind power installation ship, the cost of the wind power installation ship is high, the number is small, the schedule is uncontrollable, and the rent is extremely expensive, etc.

Embodiment
[0039] The hoisting process of key components of offshore wind turbines includes the following steps:
[0040] Step 1. If figure 2 As shown, the tugboat 1 carries machinery and equipment close to the tower;
[0041] Step 2. If image 3 As shown in , lift the small lifting bracket or the unit comes with a small crane to prepare for hoisting the docking platform and turning bracket;
[0042] Step 3. If Figure 4 As shown, hoist the docking platform and turning bracket;
[0043] Step 4. If Figure 5 As shown, through the main winch cable, under the action of the auxiliary winch, the main hoisting winch moves from the tugboat to the tower platform and fixes it;
[0044] Step 5. If Image 6 As shown, the small lifting bracket pulls the main hoisting winch to the docking platform, and passes the main winch cable to prepare for hoisting;
[0045] Step 6. If Figure 7 As shown in , the stand-up support rotates outward around the pin shaft, ready to dock with the main crane; t...

The invention relates to a hoisting method for key parts of an offshore wind turbine generator. The method comprises the following steps that firstly, a main crane container, a butt joint platform anda turnover support container which are placed on a tugboat are transported to close to a wind power tower cylinder through the tugboat; then a small hoisting device is used for hoisting the butt joint platform and a turnover support to a specified position of a cabin at the upper part of the wind power tower cylinder, and a main winch mooring rope is connected to an auxiliary winch on the tugboatand a main hoisting winch through a wheel train on the butt joint platform; the auxiliary winch is started to draw, and the main hoisting winch is dragged to a mounting platform and fixed; then the turnover support is rotated outwards and suspended out of the outside of the cabin, and the main hoisting winch is connected to a main crane according to the main winch mooring rope through the wheel train; the main hoisting winch is started to draw, the inverted main crane is lifted to the height of the cabin and is in butt joint with the turnover support, a power driving device drives the turnover support to rotate and turn over 135 degrees, and the inverted main crane is turned over; and finally, the turning over main crane is fixed on the cabin, and hoisting operation can be carried out.
Description
technical field [0001] The invention relates to an installation method of an offshore wind turbine, in particular to a method for hoisting key components of an offshore wind turbine. Background technique [0002] At present, the offshore wind power project has been fully launched, because it started late, and the relevant supporting technologies in this area are not yet mature in our country. It is mainly reflected in the following aspects: the damage rate of wind turbine components is high during operation, and key components need to be replaced frequently within 20 years of service; there is a lack of professional wind power installation equipment reserves; the threshold for large-scale wind power installation equipment is high, and the cost Expensive, which further restricts the development of sea power hoisting. [0003] Specialized wind power installation ships are generally used to hoist high-power offshore wind turbines. The only wind power installation ships in Chin...
