Problems solved by technology

The two installation methods have their own disadvantages. The offshore construction of separate installation is more complicated and difficult, and the construction period is longer; the overall installation requires large barges and large lifting equipment, and the installation cost is high. It is not suitable for the construction of large-scale offshore wind farms.

Embodiment Construction

[0033] As shown in the figure, the installation frame system includes a lifting device and a mounting frame 1 installed on the left and right sides of the bow. The lifting device is mainly composed of a motor, a pulley block, a wire rope, etc., and can vertically lift the holding platform 3 and the complete fan unit. The lifting height is 60 meters and the lifting weight is 900 tons. The holding platform 3 is an open and close platform. When the wind turbine is installed, it can hold the wind turbine tower tightly and lift it. It can bear the weight of the whole wind turbine and has a lifting capacity of about 800 tons. 8 guide positioning wheels are arranged around the tight platform 3 to prevent the platform from moving along the length and width of the ship. The centralizing device 2 adopts the opening and closing type, which protects the wind turbine tower in the working state, can bear the eccentric load and wind load when the wind turbine is lifted, and prevents the wind...

Abstract

The invention relates to a mounting ship of an offshore wind turbine and a construction method thereof. The mounting ship comprises a crane, legs, a translating system and a mounting frame system, wherein the translating system is arranged at the longitudinal and middle axis of the ship body and used for translating a tower cylinder and a cabin; the mounting frame system comprises two symmetrical frames arranged at a left side and a right side of a stem, and a lifting device, and the lifting device is used for vertically lifting the whole offshore wind turbine. The translating system comprises a translating rail and a translating trolley, and the trolley is provided with an electric driving system and an operation platform. The mounting frame system further comprises an enclasping platform and a centering device, wherein the enclasping platform is arranged on the mounting frame and used for encaslping and lifting the tower cylinder of the wind turbine, and the centering device is arranged on the mounting frame and used for enclasping and protecting the tower cylinder of the wind turbine and contacts the tower cylinder of the wind turbine in a roller manner. Due to the adoption of the structure, a mounting method of assembling separately from top to bottom and integrally locating when mounting is adopted, and the invention has advantages of low construction difficulty, low mounting cost and good technical effects.

Description

technical field [0001] The invention relates to the field of engineering technology, in particular to an offshore fan installation ship and a construction method thereof. Background technique [0002] Currently, there are two installation methods for offshore wind turbines: separate installation and integral installation. Both installation methods are realized by wind turbine installation ships or large offshore cranes. Split installation refers to the installation of various components of the wind turbine from bottom to top on the foundation of the wind turbine at sea; the overall installation means that the wind turbine assembled on the shore is transported to the offshore installation site as a whole, and then installed on the wind turbine foundation . The two installation methods have their own disadvantages. The offshore construction of separate installation is more complicated and difficult, and the construction period is longer; the overall installation requires l...
