Problems solved by technology

[0002] At present, the installation and construction of offshore wind turbines usually use large floating cranes to hoist the tower as a whole and then insert it into the steel pipe piles exposed to the sea. The flanges are connected and fixed, and then the wind turbines are hoisted to the top of the wind tower for installation and connection to complete the installation. Construction, the entire construction period is long, and large-scale special floating cranes are required, which makes construction difficult, expensive, and risky

Embodiment Construction

[0019] Wind turbine cabin (12) and blade (13) are hoisted on the special barge (16) and fixed at the wharf, as figure 1 . The offshore wind power generating set (12) and the jack-up wind generating set hoisting platform (1) are transported to the installed offshore wind tower body (14) by the special barge (16), and the special barge (16) will self-lift The hoisting platform (1) of the type wind power generating set is installed at the lower part of the wind tower body, and the top of the tower body is evenly distributed with four sets of hoisting points for lifting steel strands (4), and the steel strands pass through the four pulling points installed on the hoisting platform. Pull the lifting jack (3), such as image 3 . Start the hydraulically driven steel strand lifting jack (3), so that the hoisting platform (1) is lifted step by step to the top of the wind tower body, the rotating beam (5) is closed and locked, and the eight locking cylinders (2) on the hoisting platfo...

Abstract

A method for the structural design and engineering of an offshore wind power generator unit hoisting platform is provided, which is characterized in that: a special barge is adopted to convey the offshore wind power generator unit and a self-elevating wind power generator unit hoisting platform to an offshore wind tower body that has been installed beforehand; elevate a hoisting platform (1) step by step to the top of the wind tower body; lock and elevate the hoisting platform (1) with the wind tower body (14); elevate a hoisting pallet (10) and the wind power generator unit (12) to the top of the wind tower body (14) and then displace them to the position right above the top of the tower body (14), overlap with a connecting center at the top of the tower body and then carry out connection and fixing; hoist a blade (13) to the to the top of the wind tower body (14); install the blade (13) on the generator unit. Finally, lower down the hoisting platform step by step and return it to the special barge to complete the hoisting operation.

Description

technical field [0001] The invention belongs to the innovation of the installation and construction method of the offshore wind power generating set. Background technique [0002] At present, the installation and construction of offshore wind turbines usually use large floating cranes to hoist the tower as a whole and then insert it into the steel pipe piles exposed to the sea. The flanges are connected and fixed, and then the wind turbines are hoisted to the top of the wind tower for installation and connection to complete the installation. Construction, the entire construction period is long, and large-scale special floating cranes are required, which is difficult, expensive, and risky. Contents of the invention [0003] In order to solve the limitation of using large-scale special floating cranes for the installation and construction of offshore wind turbines, reduce the difficulty of construction, and shorten the construction period, the present invention provides a st...
