Problems solved by technology

A further disadvantage of the known devices is that they can only be compared with insufficient precision due to the relatively long and free-ended rod assembly on the transport vehicle and the considerable weight of the components to be replaced, such as the burner and the transition tube. positioned at the component opening through which they will be introduced into the turbine

Embodiment Construction

[0076] figure 1 A typical installation position of the turbine component 7 used in the turbine 30 is shown in. The turbine component 7 of this example is a combustor installed in the turbine 30. For maintenance or replacement, the combustor must be pulled out by displacement 27 so that the turbine component 7 is in the position indicated by the dashed line. Once the turbine component 7 is pulled to the outer position, it can be removed from the turbine without disturbing the turbine housing or other parts that can hinder its movement.

[0077] Specifically, it is difficult to remove the heavy turbine component 7 from the turbine 30 on the lower half of the turbine 30 that cannot be directly accessed by the overhead crane. The mounting system 9 includes a track structure 1 attachable to the turbine 30. in figure 2 In the example of, the track structure includes the monorail 2, and the turbine member 7 (combustor in this example) can be movably attached to the monorail 2 by mean...

Abstract

The disclosure pertains to a mounting system (9) for mounting and / or removing a turbine component (7) from a turbine (30). The mounting system (9) comprises a suspended rail structure (1) for moving the turbine component (7) with a traveller (10) which movably connects a holder (11, 12) for holding the turbine component (7) to the rail structure (1). It further comprises a lifter (5) with a support frame (3) which is attachable to the lifter (5) and configured for receiving the turbine component (7) with the holder (11, 12). The disclosure further refers to a method for mounting and removing a turbine component (7).

Description

Technical field [0001] The invention relates to a replacement system for large parts or components of a turbine. Its application is to remove or install turbine components to inspect, repair or replace them. Furthermore, it relates to a method for removing or installing turbine components. Background technique [0002] Turbine parts or components need to be removed for inspection, maintenance and repair or replacement parts or components. Such a component may be, for example, an incinerator of a gas turbine for thermal power generation. Incinerators are typically arranged at the middle of the main body of the gas turbine at equal intervals in the radial direction, and are inserted and assembled to it via flanges. Conventionally, such parts are manually replaced by constructing a simple scaffold by removing pipes and other obstacles around the part, and by suspending the part by a worker on the scaffold operating an overhead traveling crane. [0003] Parts or components such as ...
