Definitions

  • the invention relates to a manipulator for inspecting points of a steam generator that are difficult to access.
  • the U-shaped heating pipes in the area of the pipe bend are provided with tensioning bands or stiffeners with which the pipes are held and stabilized in the area of the bend.
  • These tensioning straps are generally formed from a plurality of sheets welded or screwed to one another offset from one another. It is necessary to carry out a visual inspection of these straps at regular intervals.
  • the space available between the floor area and an overlying coarse separator opening is limited and difficult to access, so that a remote-controlled video camera or videoscope must be used for optical control, which is manipulated by a manipulator inserted into this intermediate area the pipe bend area can be moved. This manipulator must both be able to be introduced into the area below the coarse separator opening and also have a sufficient range and mobility so that all test positions can be reached.
  • the invention is based on the object of specifying a manipulator for inspecting a steam generator which is easy to handle and which can also be used to reach locations in the steam generator which are difficult to access.
  • a manipulator that can be assembled from several members is provided, which contains a pivotable curved arm which is adapted to the curvature of the pipe bend region and has a free end on which an inspection device is arranged so as to be movable in the longitudinal direction.
  • the manipulator contains a holding arm which can be inserted into an opening of the coarse separator plate and on the free end of which a shaft which carries the pivotable arm is mounted and which can be positioned at least approximately flush with the longitudinal axis of the steam generator.
  • the drives required for the pivoting movement of the arm and for moving the inspection device are preferably arranged in the vicinity of the opening.
  • flexible shafts are provided for transmitting the pivoting movement of the arm and for moving the inspection device from the drives to the pivotable arm or to the inspection device.
  • FIG. 1 shows a manipulator according to the invention, which is introduced below the coarse separator plate of a steam generator.
  • Figure 2 illustrates the inspection area achievable with a manipulator according to the invention.
  • the heating pipes 3 are combined in an upright steam generator 2 of a nuclear power plant to form a tube bundle which forms a U-shaped pipe bend region 6.
  • the Heating tubes 3 of the tube bundle fixed by tightening straps 4.
  • These straps 4 are composed of a plurality of sheets which are welded or screwed to one another at nodes 5.
  • These nodes 5 must be checked optically at regular intervals in order to ensure the mechanical stability of the tension bandage held with the tensioning straps 4.
  • the optical control is carried out by means of a remote-controlled inspection device 8, for example a video camera or a videoscope, which is arranged on a curved arm 16 of a manipulator 10 composed of a plurality of links 12, 14, 16.
  • the video camera 8 is arranged on a camera carriage 80 which can be moved along the curved arm 16 in the directions indicated by the double arrow 82.
  • the curved arm 16 is adapted in its curvature to the curvature of the pipe bend region.
  • the camera 8 is pivotably arranged on the camera carriage 80 in the direction of the double arrow 84.
  • the arm 16 is connected via a shaft 15 to the free end of a holding arm 14.
  • the shaft 15 is rotatably mounted in the holding arm 14 and fixed on the arm 16.
  • a gear 17 engages in the shaft 15, with which the arm 16 can be pivoted about the shaft axis.
  • the holding arm 14 and the shaft 15 are preferably positioned such that the shaft axis is approximately aligned with the vertical longitudinal axis 18 of the steam generator 2.
  • the horizontal holding arm 14 is connected via a plug connection 13 to an upper arm 12 which projects vertically downwards into the space between the coarse separator plate 22 and the pipe bend 6.
  • This upper arm 12 is in one Adapter plate 36 fixed an opening 24 located in the coarse separator plate 22.
  • the curved arm 16, the holding arm 14 and the upper arm 12 are detachably connected to one another in order to enable the manipulator 10 to be inserted into the opening 24.
  • Drives 38 and 40 for the swivel gear 17 and the camera carriage 80 are arranged on the adapter plate 36.
  • the drive torques for the longitudinal displacement of the camera carriage 80 and for the rotary movement of the curved arm 16 are transmitted by flexible shafts 44 and 42, respectively.
