A device for removing and/or installing an annular component, which is arranged at a position within a turbine housing, which position is accessible via an access point of the turbine housing. A method for removing and for installing a component of this type by a device of this type.

Method and device for removing and/or installing an annular component

A device for assembling and disassembling a component of a gas turbine, having a rail system with at least two running rails. A carriage which can be pushed on the running rails along a specified movement axis is provided on the running rails, and the carriage has a securing device which is designed to secure a fitting section of a first carriage insert in a force-fitting manner such that the first carriage insert is moved together with the carriage when the carriage is moved on the running rails.

Device for assembling and disassembling a component of a gas turbine

A mounting system for a gas turbine, includes two rails, on each rail a fastening portion for fastening the rail on a manhole of the gas turbine, and for each rail at least one displacement element, which can be displaced along the rail. With the aid of such a mounting system, maintenance tools and/or turbine components are straightforwardly passed through a manhole and displaced to their location of use.

Mounting system for a gas turbine, and associated gas turbine

A crane system having a gas turbine that has a manhole on the outer housing thereof, the manhole being designed to open up a maintenance access to hot gas parts of the gas turbine in the open state of the manhole, which is provided with a fastening section; the crane system further has a hoisting mechanism that includes a mating fastening section which is connected to the fastening section of the manhole in such a way that the hoisting mechanism introduces weights that same has to lift into the outer housing of the gas turbine.

Gas turbine having a lifting mechanism

The invention relates to a device for installing and removing a component on a gas turbine, having a rail system on which in particular a rotor can be displaced along a predetermined displacement axis, and having a terminal positioning part which is fixedly connected to the rail system. The positioning part has at least one guide portion which is designed to co-operate mechanically with a respective counterpart guide portion on the housing of the gas turbine, in order to achieve a suitable orientation of the device with respect to the housing of the gas turbine. The positioning part also has at least one connecting section which is designed in each case to form a fixed but releasable connection to a respective counterpart connecting section on the housing of the gas turbine construct.

Device for installing and removing a component on a gas turbine

A method is provided for pulling a bearing body off the rotor of a gas turbine having a casing, while the casing is closed. The method includes fixing a shaft extension on the relevant end of the rotor. In order to free the bearing body of the weight of the rotor, the method involves supporting the rotor and/or holding the rotor. The method further includes fitting sliding elements between the bearing body and the rotor, and moving the bearing body axially along the machine axis onto the shaft extension.

Method for pulling a bearing body off the rotor of a gas turbine and tubular shaft extension

A method and a device are provided for removing a turbine bearing or a bearing segment of a preferably stationary turbo engine, having a housing that may preferably be split in half while the housing is closed. The method includes: supporting the rotor to relieve the turbine bearing of the weight of the rotor, fastening a support plate to a turbine bearing housing, attaching two parallel, rail-like supports to the support plate and fastening a cross-beam to ends of supports, fastening a counter-bearing plate having at least two push/pull rods to the turbine bearing housing, and fastening the push/pull rods to the turbine bearing and detaching the fastening of the turbine bearing from the turbine bearing housing and pulling the turbine bearing located in the operating position thereof out of the turbine bearing housing with the aid of the push/pull rods.

Method for removing and/or installing a turbine bearing and a device for carrying out the method

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.
