Abstract
A holding structure associated with a lifting device for supporting a removed turbine engine cover plate assembly. The holding structure includes an upper support member and a lower support member. The upper support member is formed with a plurality of service areas, where each service area is configured for servicing a cover plate assembly. Each service area includes a plurality of slots extending inwardly from a peripheral edge of the upper support member to receive and support components of the cover plate assembly during a disassembly and service operation.
Claims8
A method for servicing a turbine engine cover plate assembly comprising a cover plate having an inner side, an outer side, a C-stage ring extending from the inner side and a central aperture extending between the inner and outer sides, the cover plate assembly further including a basket extending from the inner side of the cover plate, and a support housing having an upper portion located adjacent the outer side of the cover plate and a lower portion extending through the aperture in the cover plate, the method comprising:
- providing a holding structure associated with a lifting device, the holding structure comprising an upper support member defining an upper surface and having a first slot defining a slot extending inwardly from an edge of the upper support member for receiving the C-stage ring of the cover plate;
- removing the cover plate assembly from the engine;
- disposing the cover plate assembly onto the holding structure by moving the C-stage ring of the cover plate into the first slot of the upper support member of the holding structure such that the inner surface of the cover plate engages the upper surface of the upper support member to support the cover plate assembly on the holding structure, wherein the first slot has an interior cross sectional dimension less than an outer cross sectional dimension of the cover plate and greater than an outer cross sectional dimension of the C-stage ring of the cover plate;
- and
- performing a service operation on the cover plate assembly.
