Abstract
Disclosed is a rotor blade inspection device having a maintenance chamber through which a rotor blade can pass vertically, wherein the floor opening and a roof opening, through which the rotor blade can pass, are arranged in the chamber floor and in the chamber roof of the maintenance chamber, characterized in that the maintenance chamber is arranged on a supporting frame, and in that the bracing frame can be supported on a tower of a wind turbine, and in that the chamber floor and the chamber roof of the maintenance chamber are respectively designed as a diaphragm system in order to minimize a gap between the floor opening or roof opening and the rotor blade.
Claims14
A rotor-blade inspection rig, comprising:
- a bracing frame configured for support on a tower of a wind turbine;
- a carrying frame connected to the bracing frame such as to allow movement of the bracing frame in relation to the carrying frame;
- and
- a maintenance chamber arranged on the carrying frame and configured for passage of a rotor blade in a vertical direction, said maintenance chamber including a chamber floor with a floor opening and a chamber roof with a roof opening to allow passage of the rotor blade, the chamber floor and the chamber roof each configured as a diaphragm system to minimize a gap between the floor opening or the roof opening and the rotor blade, said maintenance chamber rotatable in a horizontal plane wherein a rotation axis of the maintenance chamber coincides with an axis of the rotor blade and a twist in the rotor blade such that the maintenance chamber is turned relative to the fixed carrying frame.
