Abstract:
1. A pitch lock system for a wind turbine with a rotor, said rotor comprising at least one pitchable blade, where at least a part of said at least one blade is connected to an interface, said interface comprising a pitch bearing construction with a first bearing ring and a second bearing ring, for pitching the at least a part of said at least one blade in relation to said rotor, wherein the pitch lock system comprises a movable toothed segment for interacting with at least one toothed element, where said toothed segment is slideably connected with one of the first and second bearing rings, and where said at least one toothed element is in fixed connection with the other of the first and second bearing ring, and where the pitch lock system further comprises an actuator for activating and moving said movable toothed segment in a direction parallel to a radial direction of the bearing ring and into engagement with said at least one toothed element and thus locking the pitch bearing construction wherein the toothed segment is arranged on a fixture, where said fixture comprises means for adjusting of the fixture in at least a direction orthogonal to the radial direction, in relation to the at least one toothed element.
