Abstract

A device for installing and removing a component, preferably a burner or a transition pipe of a gas turbine, on or in a stationary gas turbine, is provided. The device includes a rail system having a frame carriage that can be moved along the rail system, on which frame carriage an insertion unit having a carrier unit for the component that can be moved along a movement axis is arranged. In order to specify an especially space-saving and especially rigid design, by means of which components of a gas turbine can be installed and removed relatively simply and quickly, the rail system is designed as a two-track rail system and the movement axis extends between the two rails transversely to an area that extends between the rails.

First claim

The invention claimed is:

1. A device for installing and removing a component on or in a stationary gas turbine, comprising:
a rail system having a frame carriage adapted to be moved on and along it and on which there is arranged an insertion unit having a carrier unit for the component adapted to be displaced thereon along a displacement axis,
wherein the rail system has two rails, such that the two rails of the rail system are configured so as to be attached to a wall section of the gas turbine, the wall section comprising an insertion opening therethrough, and
wherein the displacement axis extends between the two rails, perpendicularly to a plane defined by the rails.

2. The device as claimed in claim 1 ,
wherein the rail system is formed as an endless circular path or as an arc of a circle.

3. The device as claimed in claim 1 ,
wherein the rail system comprises, for each rail, a plurality of rail holders for attaching the rail system to a gas turbine.

4. The device as claimed in claim 1 ,
wherein the frame carriage comprises, for each rail of the rail system, at least two roller carriages adapted to be moved synchronously on the respective rail.

5. The device as claimed in claim 4 ,
wherein the roller carriage comprises at least two rollers.

6. The device as claimed in claim 4 ,
wherein the two rails have in each case an inner side, facing the other rail, on which rollers of the roller carriages are adapted to roll.

7. The device as claimed in claim 6 ,
wherein the rollers lie against the two rails under prestress.

8. The device as claimed in claim 1 ,
wherein the insertion unit comprises at least two linear rails having supporting rails, along which the carrier unit is adapted to be displaced.

9. A gas turbine having a number of insertion openings, arranged in a wall section, for installing gas turbine components,
wherein rails are attached to the wall section and the rails are formed as the rails of a device as claimed in claim 1 .

10. A method for installing and removing a component of a gas turbine, comprising:
arranging a device as claimed in claim 1 on a housing of the gas turbine such that the insertion opening is provided between the two rails; and
installing the component of the gas turbine on or in the gas turbine and/or removing the component of the gas turbine by means of the device.

11. The method as claimed in claim 10 ,
wherein the component comprises a burner or a transition pipe of the gas turbine and the insertion opening constitutes a burner opening of the gas turbine.

12. A device for installing and removing a component on or in a stationary gas turbine, comprising:
a rail system comprising two rails attached to a combustor section outer casing of the gas turbine, wherein the combustor section outer casing comprises an insertion opening disposed therethrough and between the two rails;
a frame carriage adapted to be moved on and along the rail system;
an insertion unit arranged on the carriage frame; and
a carrier unit arranged on the insertion unit and adapted to be displaced on the insertion unit along a displacement axis,
wherein the displacement axis extends between the two rails, transverse to a surface of a shape bounded by the rails.

13. A device for installing and removing a component on or in a stationary gas turbine, comprising:
a rail system comprising two rails attached to a combustor section outer casing of the gas turbine, wherein the combustor section outer casing comprises an insertion opening disposed therethrough and between the two rails;
a frame carriage adapted to be moved on and along the rail system;
an insertion unit arranged on the carriage frame; and
a carrier unit arranged on the insertion unit and adapted to be displaced on the insertion unit along a displacement axis,
wherein the displacement axis extends between the two rails, normal to a surface of a frustoconical shape defined by the rails.
