Abstract

PROBLEM TO BE SOLVED: To provide a turbine machine in which partly detachment becomes unnecessary within a conventional range in order to inspect and replace constituents. SOLUTION: In a turbine machine 1 provided with a casing 2, a rotor is supported inside the casing 2 including constituents 5 such as a combustion chamber and a cooling mechanism. An annular support structure 3 is housed inside the casing 2 for the turbine machine 1, and is turnably supported inside the casing 2 in such a manner as to be locked at one or more positions. All the constituents 5 to be periodically inspected or replaced are assembled to the annular support structure 3.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a turbine machine having a casing, in which a rotor is mounted in the casing, and the casing has components such as a combustion chamber and a cooling mechanism. Format

[0002]

BACKGROUND OF THE INVENTION Turbine machines require that components be managed or removed and replaced periodically in connection with maintenance operations. This usually requires removal of the upper part, ie the upper half shell of the casing of the turbine machine, in order to gain access to these components. Such partial disassembly is extremely laborious, time consuming and therefore costly. In particular this is often only to ensure that the components to be tested can continue to function. Further, such partial disassembly requires an improperly large assembling time as compared with the actual inspection time.

[0003]

An object of the present invention is to provide a turbine machine which avoids the above-mentioned drawbacks and does not require partial disassembly in the conventional range for inspection and replacement of components. To provide.

[0004]

According to an embodiment of the present invention, an annular support structure is provided in a casing of a turbine machine, and the annular support structure is provided in the casing. It is rotatably mounted and lockable in at least one position, so that all components to be inspected or replaced on a regular basis are mounted on this annular support structure. did.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram of an embodiment of the present invention.

[0006] In the turbine machine 1 provided with the casing 2, an annular support structure 3 is provided in the casing 2. A rotor 4 is supported in the casing 2, and the casing 2 includes peripheral components such as a combustion chamber,
It has a cooling mechanism and the like. This annular support structure 3
It is rotatably mounted in the housing 2 and can be locked in at least one position. All components 5 to be inspected or replaced on a regular basis are mounted on this annular support structure 3. During the inspection of the turbine machine 1, the annular support structure 3 is on the one hand adapted to be able to be pivoted to a different mounting position or an inspection position, if necessary, during the inspection of the turbine machine 1. Is locked in the operating position and, on the other hand, is connected to a device which moves it to the required assembly or inspection position. Annular support structure 3
Such a device for pivoting is arranged between the casing 2 and the annular support structure 3 or between the support structure 3 and the rotor 4. The casing 2 of the turbine machine 1 has at least one closable mounting opening 6. I want to manage this assembly opening 6,
Or, it has a size and a shape such that the component group 5 of the turbine machine 1 to be replaced can be easily accessed or such a component group 5 can be easily assembled and removed. In particular, if a plurality of mounting openings 6 are provided, these mounting openings 6 are arranged in mainly two planes perpendicular to the axis, corresponding to the structure 5 provided inside the casing 2. ing. This ensures that the component group 5 of the turbine machine 1 is accessible, thereby significantly reducing downtime. For this reason, in the turbine machine thus formed, it is no longer necessary to partially remove the casing in order to gain access to the component group 5 which one wishes to replace or manage. This results in significant omissions during inspection.
