Abstract
The invention relates to a device (100), a system (10) and a method for modifying the cross section of a tower section (1) of a wind turbine, wherein the tower section comprises a flange (4) located at an end (3) of the tower section having a plurality of through holes (5) spaced around its circumference for securing said tower section to another wind turbine section. The method comprises securing tensioning mechanism (14) to each of a pair of said plurality of through holes in the flange of the tower section, said pair of holes being generally opposed; and applying a tensile force between said pair of holes in the flange of the tower section.
Claims19
A device for securing a tensioning mechanism to a flange located at an end of a tower section of a wind turbine, the device comprising:
- an expandable securing member configured to be located within a hole in the flange, said hole being one of a plurality of through holes spaced around the circumference of the flange for securing said tower section to another wind turbine section;
- and
- an expansion mechanism configured to expand the securing member, so as to urge the securing member into contact with an internal wall of said hole such that the securing member is braced against the internal wall and removal of the expanded securing member from said hole is thereby inhibited by frictional resistance between the securing member and the internal wall;
- wherein the securing member has at least one attachment element configured to couple to the tensioning mechanism.
A method for modifying the cross section of a tower section of a wind turbine, wherein the tower section comprises a flange located at an end of the tower section having a plurality of through holes spaced around its circumference for securing said tower section to another wind turbine section, the method comprising:
- securing a tensioning mechanism to each of a pair of said plurality of through holes in the flange of the tower section, said pair of holes being generally opposed;
- and
- applying a tensile force between said pair of holes in the flange of the tower section).
