ABSTRACT:
A device for cleaning and servicing a weld site about the periphery of a extending control rod drive mechanism and adapter tube including a housing adapted to be positioned adjacent to and rotated about the periphery of the control rod drive mechanism and a carriage assembly including an inner and outer portion reciprocably received within the housing is provided. Mounted within the housing is a first drive motor for driving a threaded lead screw rotatably mounted within the housing with an internally threaded follower secured to the carriage assembly and mating with the threaded lead screw for reciprocating the carriage assembly relative to the housing in a direction substantially parallel to the control rod drive mechanism. A second drive motor is reciprocably mounted within the carriage assembly for receiving and driving a tool attachment, and a third drive motor for reciprocating the second drive motor and the tool attachment in a direction substantially perpendicular to the control rod drive mechanism are provided. The third drive motor is similarly connected to a second lead screw rotatably mounted within the inner portion of the carriage assembly with a second internally threaded follower assembly mating with the lead screw for displacing the outer portion relative to the inner portion so that the tool attachment is remotely positioned relative to the control rod drive mechanism by operation of the first and third drive motors.
