Mounting device for offshore wind generating set based on six-dimensional intelligent mechanical legs

Abstract

The invention discloses a mounting device for an offshore wind generating set based on six-dimensional intelligent mechanical legs. The mounting device comprises a large crane ship, fine positioning buffer system, a fixing mechanism and a tower footing platform, the crane ship floats on the sea, a lifting system of the crane ship is rotatably connected with a translational system of the crane ship, and the crane ship controls the position of a fan through a steel wire rope. The upper end of each six-dimensional intelligent mechanical leg of the fine positioning buffer system is hinged with a flat plate and is fixedly connected with a fixing truss, the lower end of the fixing flat plate is hinged with a cylindrical pin, the cylindrical pin is fixedly connected with a small cylinder, and the small cylinder and a positioning cylinder 1 are concentric. A fan tower is positioned by the aid of the six parallel six-dimensional intelligent mechanical legs, and the position of the fan tower is controlled by the aid of a video sensor, so that the fan tower is rapidly and accurately mounted by the aid of the crane ship, collision is avoided in the mounting process, and time and mounting cost are greatly saved.

Description

technical field [0001] The invention relates to an overall installation engineering technology of an offshore wind power generating set, in particular to an installation device for an offshore wind generating set based on a six-dimensional intelligent mechanical leg. 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 large crane 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, when the wind turbine tower is connected to the foundation platform, it wil...

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, when the wind turbine tower is connected to the foundation platform, it will not only make it difficult to quickly align and align the flange bolt holes, but also It affects the positioning of the positioning hole of the wind turbine tower, which affects the fast and fixed installation of the wind turbine on the foundation platform, and may also cause severe impact and collision between the wind turbine and the foundation platform, thereby damaging the expensive wind turbine and affecting the entire wind power plant. field construction

[0003] After searching the existing technology, it is found that an automatic positioning and centering device for the overall installation of offshore wind turbines (Chinese application number 200920157232.2) has the following deficiencies: 1. The automatic precise positioning and centering device has tangential and radial positioning and vertical buffering It is realized through 3 different institutions, which leads to complicated institutions and greatly increases the production cost

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 are torsion when the center is centered, and the tangential positioning device of this patent cannot achieve a large-angle torsion, and there are work 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
