Fixture for retaining an end of a member

摘要

A fixture for attachment of an end of a member, such as a wind turbine tower section, blade or hub for a wind turbine characteristically has an end flange. To enable clamping while being able to compensate for different hole patterns in the flanges, by the invention, the fixture provides for retaining of ends of members with flanges, regardless of flange diameter and hole patterns, and which is also quickly and easily installed. Additionally, it is possible to firmly clamp the flange end to upstanding frame parts of the fixture with fastening elements, thereby providing a stable connection between a console of the fixture and the upstanding frame parts.

1. Fixture for retaining of an end of at least one wind turbine component from the group consisting of wind turbine blades, wind turbine hubs, and wind turbine tower sections, during transport, said fixture comprising:
an axial control/retaining mechanism in the form of a first lower console for counteracting of a relative horizontal displacement between the end of the at least one wind turbine component and the fixture in a direction perpendicular to a longitudinal axis of the end of the member in use, said console includes cross-positioning means for positioning the end of the at least one wind turbine component in relation to the fixture during fastening of the fixture to the end of the at least one wind turbine component relative to a horizontal oriented direction parallel to the end of the at least one wind turbine component in use, and cross-axial holding means for counteracting of a relative displacement between the end of the at least one wind turbine component and the fixture in a transverse direction of the longitudinal axis of the at least one wind turbine component, first connection devices for attachment of the fixture to an external structure other than the end of the at least one wind turbine component and parts cooperating with at least two second connection devices for releaseable attachment of essentially vertically oriented frame parts of the fixture, wherein the console comprises a through-slit-opening located between the cross positioning means receiving a displaceable first holding device in the form of a bolt or a threaded rod with an end nut, a free end of said bolt or threaded rod being provided with a clamping nut for clamping the displaceable first holding device on said bolt or threaded rod for engagement of an oppositely facing side of a flange of the end of the at least one wind turbine component for counteracting of relative displacements between the console and the at least one wind turbine component parallel to the longitudinal axis of the at least one wind turbine component during use, and at least two pivotally mounted, threaded rods or bolts, free ends of which have nuts for clamping a displaceably mounted, second holding device on said rods or bolts, said second holding device forming said cross-axial holding means and comprising claw-shaped angular blocks for engagement against a length axis oriented side of said flange, for counteracting of horizontally directed displacement between the at least one wind turbine component and the fixture in a transverse direction relative to the longitudinal axis of the member during use, wherein the vertically oriented frame parts of the fixture comprise a first upstanding frame part cooperating with the second connection devices that is formed of two parallel columns and at least one transverse beam connecting the columns that is of a length which at least corresponds with a diameter of a respective end the at least one wind turbine component, said columns each having a through-slit-opening on a side adjacent to the end of the at least one wind turbine component, the through-slit-openings being aligned parallel to each other, and at least one displaceable threaded rod/bolt mounted in said through-slit-openings, a first end of which includes a head the diameter of which is larger than the width of the slit-shaped openings, said head engaging the respective column during use of the fixture and a second end of which is a threaded end having a nut clamping a displaceably mounted third holding device in engagement with a flange on the end of the at least one wind turbine component relative to a second frame part for counteracting of relative horizontal oriented displacement between the at least one wind turbine component and the fixture in a transverse direction relative to the longitudinal axis of the member during use.
