Six-dimensional installation device for offshore wind generating set

Abstract

The invention provides a six-dimensional installation device for an offshore wind generating set. The six-dimensional installation device for the offshore wind generating set comprises a positioning mechanism, a wind turbine, a six-dimensional parallel mechanism and a tower footing platform. The six-dimensional parallel mechanism is fixed to the tower footing platform through the positioning mechanism. The wind turbine penetrates through the center of the six-dimensional parallel mechanism and is fixed to the tower footing platform through the six-dimensional parallel mechanism. Structural connection of the six-dimensional parallel mechanism is in a 6USP mode; in other words, the six-dimensional parallel mechanism comprises six branched chains, a U-shaped pair is arranged at the upper end of each branched chain for connection, a ball pair is arranged in the middle of each branched chain for connection, and a movable pair is arranged at the lower end of each branched chain for connection. According to the six-dimensional installation device, the six-dimensional parallel mechanism is adopted, and the offshore wind generating set is rapidly positioned and installed; when transverse hydraulic rod sets work, large torque can be provided, so that bolt holes in a wind turbine tower drum flange and bolt holes in tower footing can be rapidly aligned.

Description

technical field [0001] The invention relates to a six-dimensional installation device, in particular to a six-dimensional installation device for an offshore wind power generating set. Background technique [0002] The offshore high-power wind power generation device includes two parts: the offshore foundation platform and the wind turbine. 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 up to hundreds of tons, under the action of the turbulence of the waves and the sea wind, it is difficult to align the flange holes on the wind turbine tower with the flange holes on the tower base platform by conventional means , not only a...

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 up to hundreds of tons, under the action of the turbulence of the waves and the sea wind, it is difficult to align the flange holes on the wind turbine tower with the flange holes on the tower base platform by conventional means , 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 prior art, it is found that an automatic positioning and centering device (the application number of Chinese patent is 200920157232.2) has the following deficiencies: one, the buffering and positioning functions of the automatic positioning and centering device are achieved through It is realized by two different mechanisms, and the structure is more complicated. At the same time, the increase of buffer cylinders greatly increases the production cost of the equipment

Second, 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 wind turbine in advance. When the crane ship lifts the wind turbine tower, the upper hanger mechanism needs to be lifted at the same time, which brings difficulties to transportation
