Abstract
A wind turbine blade suspension and rotation device capable of raising and lowering the blade includes a blade housing configured to receive a blade and having at least one guide on an exterior surface; a base; a first telescopic frame disposed on a first side of the base; a second telescopic frame disposed on a second side of the base; at least one adjustable strap, the adjustable strap disposed between the adjustable frames; wherein the at least one strap extends through the guide on the exterior surface of the housing to suspend the blade.
Claims17
A wind turbine blade suspension device comprising:
- a blade housing, the blade housing configured to receive a blade therein, the blade housing including at least one guide on an exterior surface;
- a base;
- a first adjustable frame disposed on a first side of the base, the first adjustable frame including a pair of spaced columns, each column having a bottom and top end, the top ends defining a first hinge point;
- a second adjustable frame disposed on a second side of the base, the second adjustable frame including a pair of spaced columns, each column having a bottom and top end, the top ends defining a second hinge point;
- at least one adjustable strap, the adjustable strap disposed between the adjustable frames and extending over at least one hinge point;
- wherein the device has an expanded position and a collapsed position, the first hinge point and the second hinge point spaced apart by a first distance when the device is in the expanded position, and the first hinge point and the second hinge point spaced apart by a second distance when the device is in the collapsed position;
- and
- wherein the at least one strap extends through the guide on the exterior surface of the housing to suspend the blade;
- and
- wherein the first distance that the first hinge point and the second hinge point are spaced apart is lesser than the second distance the first hinge point and the second hinge point are spaced apart.
A wind turbine blade suspension device comprising:
- a blade housing, the blade housing configured to receive a blade therein, the blade housing including at least one guide on an exterior surface;
- a base having a top surface and a bottom surface;
- a first pair of telescopic frames disposed on a first side of the base, each of the first telescopic frames having a bottom and top end;
- a second pair of telescopic frames disposed on a second side of the base, each of the second telescopic frames having a bottom and top end;
- wherein the device has an expanded position and a collapsed position, the top end of the telescopic frames disposed above the base when the device is in the expanded position, and the bottom end of the telescopic frames disposed below the bottom of the base when the device is in the collapsed position;
- at least one adjustable strap, the adjustable strap extending from the base and disposed between the telescopic frames;
- wherein the at least one strap extends through the guide on the exterior surface of the housing to suspend the blade.
