Apparatus for orienting a guide vane support relative to a turbine casing

An apparatus for orienting a guide vane carrier relative to a turbine casing, comprising:

• a guide device comprising a first region and a second region,
• wherein the first region is arranged in a recess of the guide vane carrier and the second region is arranged in a recess of the turbine casing,
• wherein the second region of the guide device comprises a guide channel comprising a first internal thread,
• a first adjusting element comprising a first external thread arranged in the guide channel, wherein the first external thread is screwed together with the first internal thread,
• wherein the first adjusting element is arranged in the guide channel such that, when the guide device is supported against a support surface of the recess of the turbine casing, a force flow runs through the first adjusting element from the recess of the turbine casing to the guide device, and
• a second adjusting element comprising a second external thread arranged in the guide channel, wherein the second external thread is screwed together with the first internal thread, wherein the second adjusting element is arranged in the guide channel such that a force flow runs through the second adjusting element from an upper part of the turbine casing to the guide device,
• wherein the first adjusting element is secured by a securing device to the second adjusting element in the guide channel such that the first adjusting element and the second adjusting element cannot rotate relative to the guide channel, and
• wherein the securing device comprises a second screw for mutually bracing the first adjusting element and the second adjusting element in the guide channel, the second screw comprising a second-screw head and second-screw male threads, wherein the first adjusting element comprises a second internal thread for receiving the second-screw male threads.
