    The invention relates to measuring technique and can be used for eddy current control of water pipes of vertical steam generators used in nuclear power plants δ.
    A device for eddy current control of steam generator pipes is known, comprising a probe holder made of two interconnected parts, one of which, facing the sensor, is thinner than the pipe and is surrounded by a centering element in the form of a ring, and the second part in the form of a pushing sleeve C1]. 16
    However, the known device does not provide the necessary control performance because of the need to control the holder outside the steam generator during the control of each pipe. 20
    Closest to the proposed is a probe holder for monitoring the tubes of the steam generator by the eddy current method, containing a lever and a carriage pivotally mounted at one end [2]. 25
    The disadvantage of this device is the duration and complexity of the process of extracting the probe from one pipe and placing it in another.
    The purpose of the invention is the expansion of functionality.
    This goal is achieved by the fact that the holder is equipped with a support intended for fixing it on the body of the steam generator, on which the second end of the lever is fixed by means of a ball joint, a guide sleeve for the probe mounted on the carriage, covering the carriage wheels with a track with pins on the outer surface, the distance between which is equal to or a multiple of the distance between the tubes of the steam generator, and the carriage drive mounted on it, and the lever is made telescopic with means to bring it to the maximum elongation position.

The second end 8 of the lever 1 is fixed to the support 5 by means of a ball hinge 7. The holder also contains a guide sleeve 9 mounted on the carriage 4 for the probe 10. The wheels 11 of the carriage 4 are covered by a track 12 with pins 13 on the outer surface, the distance between which is equal to or a multiple of the distance between pipes 14 of the steam generator. The carriage is driven by a stepper motor 15 connected to the axis 16 of the carriage wheels
    4. Communications, the probe is located in the guide shell 17.
    The control of the steam generator pipes using the holder is as follows.
    Install the holder through the support 5 in the hole 18 of the housing 6 of the steam generator. The telescopic lever 1 is pulled out in the direction of the pipes 14 to be controlled until the carriage 4 approaches the bottom of the steam generator 19, and the lever 1 is moved until the pins 13 are inserted into the pipes
    14. This allows you to enter the probe 10 using the guide sleeve 9 and the guide sheath 17 into one of the pipes
    14.
    Upon completion of control, the probe 10 is removed from the pipe, the stepper motor 15 is turned on, leaving the lever 1 in the extended state. The carriage 4 moves along the bottom 19 and the guide sleeve 9 moves to a position against a new pipe 14 located in the direction of movement of the carriage 4. If necessary, changes in the direction of movement of the carriage 4 are blocked using the lock (in the drawing) the ball joint 3,
    - dimetric angle, again extend lever 1, 5 so that the carriage 4 comes into contact with the bottom 19, and release the ball joint 3. The pins 13 enter the holes of the pipes 14.
    When the distance between the controlled pipes 14 changes, the distance between the pins 13 is changed or the track 12 is changed.
    The present invention improves the control performance 15 and its safety, as it reduces the unproductive time of operation of the equipment.

    (54) PROBE HOLDER FOR PIPE CONTROL The invention relates to the instrumentation measurement technique and can be used for eddy current testing of water pipes of vertical steam generators used on nuclear power tools. A device for eddy current control of steam generator tubes is known. It contains a probe holder made in the form of two interconnected parts, one of which is facing the sensor thinner than the tube and is surrounded by a centering element in the form of a ring Cl. However, the known device does not provide the required control performance due to the need to orient each holder with the counter of each pipe outside the steam generator. Closest to the present invention, there is a probe holder for controlling the steam generator tubes by the eddy current method, comprising a lever and a carriage 2 pivotally fixed at one end. STEAM GENERATOR The disadvantage of such a device imposes the length and complexity of the process of extracting the probe from a single pipe and placing it in a scoop. The purpose of the invention is to expand the functionality. This goal is achieved in that the holder is provided with a support for fixing it on the steam generator housing, on which the second end of the lever is fixed by means of a ball joint and pointing to the sleeve of the bottom of the probe fixed on the carriage, the carriage wheel has a track with pins on the outer surface, the distance between which is equal or a multiple of the distance between the pipes of the steam generator and the carriage drive mounted on it, and the lever is made telescopic with the means to bring it to the B floor Maximum lengthening. FIG. 1 shows the lower part of the steam generator with the probe holder installed in the working position, a section; in fig. 2 - probe holder, side view; in fig. 3 - the same, top view; in fig. 4 with section A-A in FIG. 3. The probe holder contains a lever 1, made telescopic, with means, ensuring that we move it to the maximum position (not shown), fixed at one end of it 2 by means of a hinge 3, carriage 4, support 5 Designed for fixing the pump housing b of the steam generator. A second end 8 of the lever 1 is fixed on the support 5 by means of a ball joint 7. The holder also contains a guide sleeve 9 for the probe 1O fixed on the carriage 4. The wheels 11 of the carriage 4 are covered by track 12 with pins 13 on the outer surface, the distance between which is equal or multiple to the distance between the pipes 14 of the steam generator. The carriage is driven by a stepper motor 15 associated with the axis 16 of the wheels of the carriage 4. Communicator. The probes are located in the guide casing 17. The control of the steam generator tubes with the help of the holder is carried out as follows. Install the holder by means of the support 5 in the hole 18 of the housing 6 of the steam generator. Pull out the telescopic lever 1 in the direction of the pipes 14, which are to be monitored until the carriage 4 is close to the bottom 19 of the steam generator, and move the lever 1 before inserting the pins 13 into the pipes 14. This allows the probe Yu to be inserted using the guide sleeve 9 and the guide casing 17 into one of the tubes 14. Upon completion of the control, the probe 10 is removed from the tube, the stepper motor 15 is turned on, leaving lever 1 in the extended state. The carriage 4 moves along the bottom 19 and the guide sleeve 9 moves to a position against the new pipe 14 located on the sign of the movement of the carriage 4. When the direction of movement of the carriage 1S 4 is changed, block the ball joint 3 (in the drawing) with the catch 3 the lever 1, releasing the pins 13 from the holes of the pipes 14, rotate the lever 1 around its axis to the required angle, again push the lever 1 so that the carriage 4 comes into contact with the bottom 19, and release the ball joint 3. The pins 13 enter the holes of the pipes 14 With changing the distance between the monitored pipes 14 changes the distance between the pins 13 or. replaces the track 12. The present invention improves the control performance and its safety, as it reduces the unproductive operating time of the equipment.
