  • Patent number: 5341406
    Abstract: A sliding lance guide flexible lance system (10) is attached to a hand hole (12) of a nuclear power plant steam generator by means of flange (14) of tilt module (16). A rail (18) extends from the tilt module (16) to a support stand (20) and is attached to the stand (20) by a pivot (22) so that the rail (18) is free to rotate with the tilt module (16). A tilt drive motor (24) is attached to the tilt module (16). A flexible lance (26) extends into the rail (18) for extension through a lance guide shoe (27). The lance guide shoe (27) deflects the lance from the rail (18) into the tube gap of the steam generator. The lance guide shoe (27) is slideably mounted in the rail (18), and is attached to a lance guide belt (30), which extends within and along the rail (18). Similarly, the flexible lance (26) extends within and along the rail (18). A lance guide belt sprocket drive (40) is mounted on support (33) to engage the lance guide belt (30).
