Various embodiments include a method of displacing a turbomachine component from position in a first slot of a turbomachine spacer disk. The method can include detachably affixing a mounting member of a displacement apparatus to a second slot in the gas turbomachine spacer disk using an attachment device, rotating a displacement arm of the displacement apparatus until the displacement arm contacts the turbomachine component, and displacing the turbomachine component from the position within the first slot by linearly actuating the displacement arm with a linear actuator.

Turbomachine component displacement apparatus and method of use

A tool for removing a component from a turbomachine is provided. The tool includes a body having an alignment portion and a connection portion. The alignment portion defines a longitudinal axis and a cross sectional shape complementary to a slot defined in a rotor wheel of the turbomachine. When the tool is positioned in the slot, the connection portion is configured to contact the component. The tool additionally includes a force section connected to the body and configured to transfer a force to the connection portion in a direction substantially parallel to the longitudinal axis of the alignment portion.

Removal device

Various embodiments include methods adapted to displace turbomachine components from a location within a turbomachine. In some embodiments, a method of displacing a turbine bucket from a turbomachine wheel slot using a displacement apparatus, includes: detachably engaging an engagement arm of the displacement apparatus to the turbine bucket, the engagement arm attached to a linear actuator coupled to a body of the displacement apparatus, and the engagement arm adapted to be actuated in a first axial direction by the linear actuator; contacting the turbomachine wheel with at least two contacting portions of the body of the displacement apparatus; and displacing the turbine bucket from a position within a slot of the turbomachine wheel in the first axial direction by linearly actuating the engagement arm with the linear actuator.

Turbomachine bucket displacement apparatus and method of use

Various embodiments include apparatuses adapted to displace components from a location within a turbomachine. In some embodiments an apparatus for displacing a component of a gas turbine from a first slot in a spacer disk includes a body including a mounting member configured to affixedly attach to a second slot of the spacer disk, a linear actuator coupled to the body and a displacement arm coupled to the linear actuator, the displacement arm actuatable in a first axial direction by the linear actuator to contact the component and displace the component relative to the first slot.

Various embodiments include apparatuses adapted to displace turbomachine components from a location within a turbomachine. In some embodiments apparatuses for displacing a turbine bucket from a turbomachine wheel slot include a body having at least two contacting portions for contacting the turbomachine wheel, a linear actuator coupled to the body, and an engagement arm for engaging the turbine bucket, the engagement arm coupled to the linear actuator and adapted to be actuated in a first axial direction by the linear actuator.

Various embodiments include an apparatus for installing or removing a transition piece (TP) in a gas turbine. The apparatus can include: a control arm assembly sized to rest within an opening in the gas turbine; a guide system coupled to the control arm assembly, the guide system for transporting the TP within the opening in the gas turbine; and a counter balance coupled to the guide system, the counter balance for countering weight of the TP during the installing or the removing of the TP in the gas turbine.

Turbine transition piece (TP) apparatus and method

Various embodiments include a service apparatus for a turbomachine. The service apparatus can include: a frame for coupling to an opening in the turbomachine; a bridge member operably coupled to the frame and spanning a width of the frame, the bridge member being substantially movable along a length of the frame; and a crane member operably coupled to the bridge member, the crane member being substantially movable along the width of the frame, wherein the crane member includes at least one attachment device for attaching to an object within the turbomachine.
