Embodiment Construction

[0040] The core of the present invention is to provide a wind turbine integrally installed rotating holding mechanism, the wind turbine integrally installed rotating holding mechanism can avoid the nacelle, hub and blades above the tower, and lift the tower from the bottom of the wind turbine, conveniently realizing the wind turbine. The centering of the center of the tower and the center of the fan foundation installation base, as well as the alignment of the bolt holes of the fan tower connecting flange and the bolt holes of the fan foundation connecting flange, improve the installation efficiency of the wind turbine and reduce wind power generation. The cost of unit installation. Another core of the present invention is to provide an offshore wind turbine installation platform comprising the above-mentioned wind turbine integrally installed rotating holding mechanism.

[0041] In order to enable those skilled in the art to better understand the solution of the present inven...

Abstract

The invention discloses a fan integral installation rotary holding and lifting mechanism which comprises a gate type installation frame (2), a rotary power part (7), an upright (51) and a cradle (8) used for supporting a tower, wherein a holding mechanism (1) is arranged between two support legs (21) of the gate type installation frame (2), a lifting mechanism (4) is arranged between the holding mechanism (1) and the gate type installation frame (2), the upright (51) is positioned below the holding mechanism (1), the cradle (8) is hoisted below the holding mechanism (1) through a telescopic hoisting rope (6), and two ends of the rotary power part (7) are respectively connected with the upright (51) and the cradle (8). The fan integral installation rotary holding and lifting mechanism provided by the invention can conveniently realize integral lifting and rotating of a fan so as to realize alignment of a bolt hole of a tower connection flange and a bolt hole of a fan foundation connection flange. The invention also discloses an offshore fan installation platform.

Description

technical field [0001] The present invention relates to the technical field of installation of complete wind turbines at sea, in particular to a wind turbine overall installation rotating holding mechanism, and the present invention also relates to an offshore wind turbine installation platform including the wind turbine complete installation rotating holding mechanism. Background technique [0002] With the rapid development of my country's economic construction, electric energy has a greater impact on economic construction and people's lives, and with the rising prices of oil resources and coal resources, as well as people's increasing requirements for low-carbon and environmental protection, clean energy The advantages of wind power have become increasingly prominent, and wind power, as a kind of green energy, has attracted more and more attention from all countries in the world, and has been widely developed and utilized. [0003] Wind power generation is a power generati...
