Device for remote inspection of steam generator tubes

A device for the remote inspection of tubes comprising:

• a longitudinally extending rail assembly having a proximate and distal end;
• worksite mounting means attached to the proximate of the rail assembly;
• an elongate flexible wand guided along the rail assembly;
• a take-up reel attached to the worksite mounting means for windingly supporting one end of the elongate flexible wand;
• a carriage means attached for longitudinal movement along the rail assembly;
• and
• an inspection probe attached to a second end of the elongate flexible wand,
• wherein the rail assembly includes an elongate rail having a kickstand attached at the distal end for pivotable movement from a position aligned with a longitudinal axis of the rail to a position transverse to the longitudinal axis of the rail,
• wherein the elongate, flexible wand includes a non-circular central section defining an elongate interior channel for receiving probe cabling and two opposed longitudinally extending flat wings on each side of the non-circular central section in which each wing has a longitudinal row of indexing holes formed therein positioned remote from the non-circular section, and
• wherein the carriage means receives the second end of the elongate, flexible wand and includes a drive means for indexed movement of the flexible wand from a direction along the longitudinal axis of the rail to a direction transverse to the longitudinal axis of the rail.
