Installation device for offshore wind generating set

Abstract

The invention discloses an installation device for an offshore wind generating set. The installation device comprises a positioning mechanism, a fan, a six-dimensional parallel mechanism, a tower pedestal platform and a crane ship; the six-dimensional parallel mechanism is fixed on the tower pedestal platform through the positioning mechanism; the fan penetrates through the six-dimensional parallel mechanism and is fixed through the six-dimensional parallel mechanism; and the crane ship is connected with a fixing mechanism. The six-dimensional parallel mechanism with three working units is adopted in the installation device and does not have a working dead angle, so that deflection of positive deviation and negative deviation of a fan tower cylinder can be realized, and bolt holes in a bolt hole cylinder tower pedestal on fan tower cylinder flanges are quickly aligned. The six-dimensional parallel mechanism can play a role in buffering when the fan tower cylinder declines, so that collision impact between the fan tower cylinder and the tower pedestal is reduced. The six-dimensional parallel mechanism has a series of advantages of high rigidity, high speed, high bearing capacity, small errors, high precision, good power performance and the like and is easy to control, so that positioning and buffering integration of the fan tower cylinder can be realized, and the manufacturing cost is greatly reduced.

Description

technical field [0001] The invention relates to an integrated automatic installation and positioning device for the overall installation of an offshore wind turbine relying on a hydraulic system, in particular to an installation device for an offshore wind power generating set. Background technique [0002] Offshore high-power wind power generation devices include two parts: wind turbines and offshore foundation platforms. Offshore wind turbines are hoisted by a crane ship and transported to the offshore wind turbine foundation platform, then the lower end of the wind turbine tower and the offshore foundation platform are smoothly positioned and docked, and finally the two parts are fastened to complete the setup. However, in the process of approaching the foundation platform, due to the self-weight of the wind turbine reaching hundreds of tons, under the action of the turbulence of the waves and the sea wind, it is difficult to align and position the flange bolt holes direc...

AI Technical Summary

Problems solved by technology

However, in the process of approaching the foundation platform, due to the self-weight of the wind turbine reaching hundreds of tons, under the action of the turbulence of the waves and the sea wind, it is difficult to align and position the flange bolt holes directly between the wind turbine tower and the tower below the foundation platform by conventional means The alignment of the holes not only affects the fast and fixed installation of the wind turbine on the foundation platform, but may also cause severe impact and collision between the wind turbine and the foundation platform, thus damaging the expensive wind turbine and affecting the construction of the entire wind farm

[0003] After searching the existing technology, it is found that an automatic positioning and centering device (Chinese application number 200920157232.2) for the overall installation of offshore wind turbines has the following deficiencies: 1. The buffering and positioning functions of the automatic positioning and centering device are achieved through two different The mechanism is realized, the structure is relatively complicated, and the increase of the buffer cylinder greatly increases the production cost of the equipment

2. When the wind turbine tower is centered with the foundation platform, under the action of the turbulence of the sea waves and the sea wind, the flange bolt holes will be torsion when the center is centered, and the tangential positioning device of this patent cannot realize the large-angle torsion, and there are working conditions at the same time. blind spot

3. The size of the upper hanger mechanism is large and needs to be placed on the bottom of the fan in advance. When the crane ship lifts the fan tower, the upper hanger mechanism needs to be lifted at the same time, which brings difficulties to transportation
