  • the invention is based on the object, a simple producible flexible lance for processing and inspection of the tube sheet of a steam generator, which also in narrow pipe gaps can be introduced.
  • a flexible lance for processing or inspecting a tube sheet of a steam generator contains a flexible metallic according to the invention Tape that is arranged one behind the other in its longitudinal direction Has recesses through which a flexible supply line for one located at the free end of the tape Machining or inspection head is threaded.
  • a steel band is preferably provided.
  • a processing device Spray head and as a supply line a metallic capillary, in particular a capillary made of a nickel-titanium alloy, intended.

  • a cable to transmit a pulling force to an outdoors End of the band arranged recovery tool provided.
  • FIG. 1 shows a steam generator 2 in a horizontal partial section at the height of a hand hole 4.
  • a tube plate 6 which is visible in plan view, a plurality of heating tubes 10 open inside a cylindrical guide jacket 8 , with which a free end 53 of a flexible lance 50 can be introduced, starting from the pipe line 12, into a pipe gap 14 running perpendicular to the pipe line 12.
  • a steam generator 2 is shown with a triangular arrangement of the heating pipes 10, in which there are particularly narrow pipe gaps 14.
  • the flexible lance 50 is constructed from a band 52 on which Supply lines 58, 66, 72 for supplying one outdoors Machining or inspection head 63 arranged at the end 53, 68, 70 are arranged.
  • the transport device 20 comprises a slide plate 21, with which is parked on the tube sheet 6.
  • a walking mechanism is provided, such as from European patent 0 084 867 is known.
  • transport device 20 comprises two support bodies 22 and 24, which are relative to each other in a longitudinal axis 26 of the transport device by a pneumatically operated piston 28 are displaceable.
  • support elements 30 On each of the support bodies 22 and 24 are support elements 30 which can be pneumatically extended in pairs provided, which are opposite each other Support heating pipes 10 at the edge of Rohrgasse 12. By alternating Locking the support elements 30 and pressing the Piston 28 moves the transport device 20 in the Rohrgasse 12 forward.
  • a feed device is on the transport device 20 40 arranged which is a motor-driven drive roller 41 and one assigned to her, employed against its scope Contains guide roller 42. In the drive roller 41 and guide roller 42 the flexible lance 50 is threaded.
  • the feed device 40 contains two more on its circumference mutually supported guide rollers 43 and 44, the between the drive roller 41 and the guide roller 42 Pick up threaded lance 50 and to an angle ⁇ 1 Longitudinal axis 26 and thus to a central axis parallel to it 14 set the Rohrgasse 12. In the example of the figure is this angle 90 ° so that the lance 50 in the pipe gaps 14th can be retracted.
  • the drive roller 41 and the guide roller 43 through a circumferential belt 45 coupled together.
  • a deflection roller 46 also a belt 47 out in the area the drive roller 41 abuts the belt 45.
  • the deflection angle ⁇ 1 of the lance 50 is determined by the mutual Location of the drive roller 41 and the guide rollers 42, 43 and 44 determined on the transport device 20.
  • the feed device 40 can be advantageous in a further Design in addition relative to the transport device 20 moved parallel to the longitudinal axis 26 or around a vertical Axis can be rotated to precisely align the flexible Lance 50 to allow the pipe gaps 14.
  • FIG. 2 shows how the lance 50 constructed from the band 52 is passed through the hand hole 4 from the outside. Since the band 52 cannot be bent in the plane defined by its flat sides and the tube sheet 6 is located below the lower edge of the hand hole 4, the band 52 must be guided through the hand hole 4 with the horizontally oriented flat side and rotated through 90 ° within the steam generator 2 will.
