Embodiment
[0041] For a wind power generator project in an offshore wind farm in Jiangsu, a high-altitude docking installation method for offshore wind power generator components proposed by the present invention is used to install wind power generators. The installation steps are as follows:
[0042] 1. Assembly of the nacelle, hub and two blades of the wind turbine:
[0043] a) Hoisting machinery for wind turbines: the main crane 14 is a CC5800 1000t crawler crane installed on a large barge, and the working conditions are configured as follows: SSL working condition, main arm 90m, radius of gyration 26m, rated load 154t, auxiliary crane Machine 15 adopts 200t floating crane;
[0044] b), engine room hoisting:
[0045] Connect the special spreader to the engine room 3, and fix it on both sides of the engine room 3 with two hemp ropes to control the swing of the engine room 3, hoist the engine room 3 with the main crane 14, and lay it flat on the deck of the transport barge 13;

The invention relates to a split high-altitude butt-joint installation method of an offshore wind generating set, and belongs to a wind driven generator construction method. The split high-altitude butt-joint installation method of the offshore wind generating set is characterized in that, firstly, an engine room, a hub, two blades of a wind driven generator on land or the deck of a transport barge are assembled into a whole ( usually called 'rabbit head'); then the rabbit head, a third-section fan tower tube and a third blade are all loaded on the transport barge and transported to an installing position of the offshore wind driven generator so as to carry out general installation of the rabbit head, the third-section fan tower tube and the third blade on an operation platform; and the construction method comprises the following construction steps: firstly, assembling the engine room, the hub and two blades of the wind driven generator; secondly, adjusting and installing a foundationring of the wind driven generator; and thirdly, carrying out the split high-altitude butt-joint installation of the wind generating set. The installation method provided by the invention has the advantages of reducing the damage rate of parts of the wind driven generator generated by sea transportation and sea load, guaranteeing the installation quality of the wind driven generator and the security of operating staff, and having low construction cost.
Description
technical field [0001] The invention belongs to a wind power generator installation method, in particular to a high-altitude docking installation method of an offshore wind power generator set. Background technique [0002] my country has a vast sea area and abundant offshore wind energy resources. The potential of using offshore sea wind to generate electricity is great. With the mature development of offshore wind farm technology, the installation of large-scale offshore wind turbines has become more and more widespread. The large-scale offshore wind turbines The installation and construction are very difficult. The previous technology adopts integral hoisting, that is, the tower, engine room, hub, and blades are combined into a whole on land first, and then transported as a whole by a super-large transport barge, and then the overall hoisting is carried out by using two large-scale floating cranes. The disadvantages are: the overall center of gravity of the wind turbine is ...
