Wind blade clamp
An adaptable wind blade clamp for securely fastening and supporting a wind turbine blade during transportation. Walking beams are pivotably coupled to inner sides of the wind blade clamp jaws, and pads which contact the wind turbine are pivotably coupled to ends of the walking beams, resulting in a wind blade clamp which easily adjusts to the varying cross-sectional profiles of the wind turbine blade along its length. The wind blade clamp is optionally provided with an edge walking beam and edge pads to support and protect the leading edge of the wind turbine blade.
1. A clamping apparatus for securing a wind turbine blade, said clamping apparatus comprising:
a lower jaw;
an upper jaw, the upper jaw comprising a primary support beam depending from and pivotably coupled to an inner surface of said upper jaw;
one or more lower pads connected to said lower jaw; and
two walking beam assemblies pivotably coupled to respective ends of said primary support beam, each of said two walking beam assemblies comprising:
a walking beam, and
a plurality of upper pads pivotably coupled to said walking beam, at least two upper pads of said plurality of upper pads pivotably coupled to respective ends of said walking beam.
2. The clamping apparatus of claim 1 wherein said upper jaw is pivotably connected to said lower jaw.
3. The clamping apparatus of claim 1 , said lower jaw further comprising a side pad assembly pivotably connected to said lower surface jaw.
4. The clamping apparatus of claim 3 , said side pad assembly comprising a side walking beam and two edge pads, each of said edge pads pivotably connected to a respective end of said side walking beam.
5. The clamping apparatus of claim 1 further comprising a base and a joint assembly connecting said lower jaw to said base.
6. The clamping apparatus of claim 5 wherein said base further comprises a plurality of wheels.
7. The clamping apparatus of claim 5 wherein said joint assembly permits one degree of freedom of rotational movement of said lower surface jaw relative to said base.
8. The clamping apparatus of claim 5 wherein said joint assembly permits two degrees of freedom of rotational movement of said lower surface jaw relative to said base.
9. The clamping apparatus of claim 5 wherein said joint assembly permits three degrees of freedom of rotational movement of said lower surface jaw relative to said base.
10. The clamping apparatus of claim 1 wherein each of said plurality of lower pads is repositionable along said lower jaw.
11. The clamping apparatus of claim 1 wherein said primary support beam is repositionable along said inner surface of said upper jaw.
12. The clamping apparatus of claim 1 wherein each of said plurality of lower pads is pivotably connected to said lower surface jaw.
