Quick adjust root plate attachment for wind turbine blade molds
The present disclosure provides for a root plate assembly system, an axially adjustable, rigid connection between a metallic (e.g. steel) root plate and a composite root flange of a wind turbine blade mold. The system includes a root plate including a flange portion with at least one aperture disposed therein. The system includes a sealing collar disposed within the aperture in the root plate. The system includes at least one washer having a larger diameter than the aperture in the root plate. The system includes a threaded collar having a longitudinally extending channel and threads on an outer surfaces thereof. The system includes a fastener disposed at least partially within the longitudinally extending channel of the threaded collar. The system includes a locknut disposed above the fastener abutting the fastener and a bolt cover disposed over the locknut, the bolt cover abutting the collar.
1. A method for axial adjustment of a root plate assembly system of a wind turbine blade, the method comprising:
providing a root plate comprising at least one aperture disposed therein;
providing a threaded collar comprising a longitudinal extending channel and threads on an outer surface thereof;
providing an infused plate, the infused plate comprising at least one aperture disposed therein;
providing a fastener disposed at least partially within the longitudinal extending channel of the threaded collar and the root plate;
providing an infused composite panel to form a root flange,
positioning the root flange between the root plate and the infused plate, the root flange extending around the threaded collar and the fastener;
adjusting the threaded collar to longitudinally move the fastener relative to the root flange;
adjustably coupling the root plate and the infused plate via the fastener disposed through the longitudinal extending channel of the threaded collar disposed therebetween.
2. The method of claim 1 , wherein the threaded collar is fixed to the infused plate.
3. The method of claim 1 , wherein adjusting the threaded collar to longitudinally move the fastener comprises turning the threaded collar.
4. The method of claim 1 , wherein adjustably coupling the root plate and the infused plate comprises coupling the root plate relative to the infused plate at a variable distance.
5. The method of claim 1 , wherein the adjustably coupling the root plate and the infused plate occurs prior to the providing of the infused composite panel to form a root flange.
6. The method of claim 5 , wherein the providing of the infused composite panel to form a root flange includes filling a negative space defined between the infused plate and the root plate with a composite material.
7. The method of claim 1 , further comprising coupling a locknut to the threaded collar, the locknut inhibiting relative movement between the threaded collar and the root plate.
8. The method of claim 7 , further comprising providing a bolt covering plate, the bolt covering plate attached to an outer surface of the root plate.
9. The method of claim 8 , wherein the bolt covering plate remains spaced from the locknut.
10. The method of claim 1 , further comprising providing a sealing collar and at least one sealing washer, the sealing collar and washer circumscribing the threaded collar sealing the threaded collar from composite material.
11. The method of claim 10 , wherein each of the fastener, the threaded collar, the sealing collar and the at least one sealing washer are axially aligned in a concentric configuration.
12. The method of claim 10 , wherein the sealing collar is deformable to create a seal with the root flange.
13. The method of claim 1 , wherein the threaded collar is fixedly bound to the infused plate.
14. The method of claim 1 , wherein clockwise rotation of the threaded collar axially displaces the root flange.
15. The method of claim 1 , further comprising providing a spherical washer disposed between the threaded collar and the root flange.
16. The method of claim 15 , wherein the spherical washer comprises an outer diameter less than the outer diameter of the threaded collar.
