Abstract
A blade holding apparatus for holding one end of a wind turbine blade during handling, which blade holding apparatus includes a support structure including an opening for accommodating one end of the wind turbine blade, a clamping arrangement arranged in the opening, which clamping arrangement is realized to exert a clamping force on the wind turbine blade, and a locking arrangement for locking the clamping arrangement relative to the support structure. A method of operating such a blade holding apparatus during a handling procedure of a wind turbine blade is also provided.
Claims19
A blade holding apparatus for holding one end of a wind turbine blade during a handling procedure, the blade holding apparatus comprising:
- a support structure comprising an opening for accommodating one end of the wind turbine blade;
- clamping arrangement arranged in the opening, the clamping arrangement configured to exert a clamping force on the wind turbine blade, the clamping arrangement comprises a pair of blade gripping elements mounted on opposing sides of the opening in the support structure;
- and
- a locking arrangement for locking the clamping arrangement relative to the support structure,
- wherein at least one of the pair of blade gripping elements is moveably mounted along a side of the opening in the support structure, a motion of the at least one blade gripping element relative to the opening of the support structure is effected by the weight of the blade.
A blade holding apparatus for holding one end of a wind turbine blade during a handling procedure, the blade holding apparatus comprising:
- a support structure comprising an opening for accommodating one end of the wind turbine blade;
- clamping arrangement arranged in the opening, the clamping arrangement configured to exert a clamping force on the wind turbine blade;
- and
- a locking arrangement for locking the clamping arrangement relative to the support structure,
- wherein the clamping arrangement comprises a pair of blade gripping elements mounted on opposing sides of the opening in the support structure
- further comprising a flexible connecting means for connecting the blade gripping elements such that a downward force exerted on the connecting means results by the weight of the blade in a downward motion of the blade gripping element.
A blade holding apparatus for holding one end of a wind turbine blade during a handling procedure, the blade holding apparatus comprising:
- a support structure comprising an opening for accommodating one end of the wind turbine blade;
- clamping arrangement arranged in the opening, the clamping arrangement configured to exert a clamping force on the wind turbine blade;
- and
- a locking arrangement for locking the clamping arrangement relative to the support structure,
- wherein the clamping arrangement comprises a pair of blade gripping elements mounted on opposing sides of the opening in the support structure
- wherein the locking arrangement comprises a ratchet given by a first row of teeth arranged on a blade gripping element and a second row of teeth arranged on the support structure.
