Mounting/demounting device for combustor for use in gas turbine
First Claim
1. A mounting/demounting device for combustors of a gas turbine that is adapted to mount on or demount from a casing of the gas turbine a plurality of combustors in a circumferential direction of the casing, the mounting/demounting device comprising:
- a rail receiving stand which is movably provided on the ground;
a rail which is supported on the rail receiving stand and is disposed in the form of a circular annulus or circular arc in correspondence with the disposition of the combustors;
a slide mechanism which is mounted on the rail so as to be movable along the rail and is mounted so that the slide mechanism can enter into and retreat from an interior of the casing; and
a grip mechanism which is mounted on an end portion of the slide mechanism and grips constituent parts of the combustor including a tail pipe, a nozzle and an inner cylinder.

Abstract
In a gas turbine that is equipped, on a casing (100) thereof, with a plurality of combustors (1) in the circumferential direction thereof, there is provided a rail (4) which is supported on a rail receiving stand (3) that is movable on the ground and which is disposed in the form of a circular annulus or circular arc in correspondence with the disposition of the combustors (1). A slide mechanism (5, 5a, 6, 6a) is mounted on the rail (4) so as to be movable along the rail (4) and is mounted so that the slide mechanism can enter into and retreat from the interior of the casing (100). A grip mechanism (10) is mounted on an end portion of the slide mechanism and grips constituent parts of the combustor (1), such as a tail pipe (7), a nozzle (9) and an inner cylinder (8). Also, in another aspect of the invention, there are provided a rail (12) that is shaped like a circular arc and is revolvably supported on a revolvable carriage (11), and a grip mechanism (13) that grips constituent parts of the combustor
