Installation and method for assembling the turbine stators of a turbine

An installation for pre-assembling a plurality of turbine stators of a turbine, each turbine stator being formed of an assembly of sectors juxtaposed to one another, the installation comprising:

• an input carriage configured to convey and support a set of sectors that forms at least a portion of the assembly of sectors of one of the turbine stators of the turbine, each sector of the set comprising side faces and slots provided in the side faces and being associated with a given turbine stator;
• an output carriage comprising a plurality of trays, each tray of the plurality of trays being configured to be associated with one of the turbine stators, and an actuator configured to lift an upper tray of the plurality of trays to a tray of the plurality of trays on which the equipped sector is to be dropped;
• a device for conveying sectors comprising at least one pallet adapted to convey at least one sector of the set of sectors, the conveying device being automated;
• a first robot arm adapted to grip at least a sector of the set of sectors of the input carriage and to deposit it on the at least one pallet of the conveying device;
• an automated device for inserting sealing pads and adapted to interact with the at least one sector conveyed by the automated conveying device, the device for inserting sealing pads comprising a second robot arm adapted to insert the sealing pads into the slots in one of the side faces of one of the at least one sector of the set of sectors being conveyed to form an equipped sector;
• and
• a third robot arm adapted to grip the equipped sector conveyed by the at least one pallet of the conveying device and to deposit it and to position it on the tray associated with the given turbine stator so as to pre-assemble the given turbine stator.
