Moreover, in the operation part 11b of the case 11, the male-brain switch 15 for forward and reverse rotation of the rotation of the motor 18 (rotation holder 12) is provided in the motor 18 side surface, These push buttons 16 and 17 are exposed on the surface of the operation part 11b.

The connector 20 is attached to the lower end of the operation part 11b. The signal take-off line from the encoder 19 and the power supply line to the motor 18 are connected to the connector 20.

The probe described above is detachably attached to the mounting frame 12c of the rotary holder 12. That is, the transducers can be mounted to the rotary holder 12 by inserting the pressing portions 3a and 3a of the pair of levers 3 and 3 of the transducer from the upper portion of the frame of the mounting frame portion 12c of the rotary holder 12. Can be.

At this time, since the pressing portions 3a and 3a of the levers 3 and 3 are urged to be opened outward by the coil spring 4, the pressing portions 3a and 3a are attached to the mounting frame portion 12c by this biasing force. Is temporarily fixed within.

When removing the transducer from the rotary holder 12, the transducer may be pulled out from the mounting frame portion 12c upward by pressing the pressing portions 3a and 3a of the levers 3 and 3 to close the gap.

The grip 14 is to install the case 11 of the ultrasonic flaw detection scanner to the pipe by detachably grasping the pipe to be inspected, so that the probe and the pipe mounted on the scanner come into close contact with each other.

As shown in FIGS. 6 and 7, the grip 14 includes a pair of levers 14a and 14a and a pair of opposed rotating pieces attached to the ends of the pair of levers 14a and 14a. 14b, 14b, and the spring 14c attached between the pair of levers 14a, 14a and always biased so that the pair of levers 14a, 14a are separated from each other.

An attachment hole 14d is drilled in the upper portion of the lever 14a, and the lever 14a is screwed so as to be rotatable in the mounting portion 11a of the case 11 by using the attachment hole 14d.

The upper portion of the attachment hole 14d of the lever 14a has a thin plate shape, and the rotary piece attachment hole 14e and the rotary piece attachment hole stepper 14g are formed in this portion. The rotating piece 14b is pinned to the rotating piece attachment hole 14e so as to be rotatable.

The rotating piece 14b has the special shape as shown in FIG. The rotating pieces 14b are each formed by drilling a pin hole 14f in the center of a disk made of steel, for example, and forming three right-angled cutting portions from the outside of the plate toward the pin hole 14f. The distance between the right angled corner portion of the cutting portion and the pin hole 14f may be configured differently. Moreover, three knock pins 14h ... of the protruding shape are provided.

This cutting part is able to correspond to pipes of different outer diameters to be inspected, a large diameter pipe can be accommodated in the cutting portion close to the distance between the corner portion and the pin hole 14f, the rotation of this embodiment In the case of the piece 14b, three types of different outer diameter pipes can be applied.

The rotary piece 14b rotates in the upper portion of the lever 14a as described above by inserting a pin into the pin hole 14f and inserting the pin into the rotary piece attachment hole 14e of the lever 14a. It can be attached as possible, and is fixed by the rotating piece attachment hole stepper 14g and the knock pin 14h.

In such a grip 14, the pair of rotary pieces 14b and 14b are always in contact with each other by the elasticity of the spring 14c, and the levers 14a and 14a are responsive to the biasing force of the spring 14c. As the noise, the rotating pieces 14b and 14b are separated from each other.

At this time, the respective cutting portions of the rotary pieces 14b and 14b are of the same type, and the grip 14 is temporarily attached to the pipe by holding the outer diameter pipe corresponding to the cutting portion to release the grip force applied to the levers 14a and 14a. It can be mounted as.

In this state, the pipe is located in the U-shaped cutting portion of the mounting portion 11a and is configured such that its outer circumferential surface closely adheres to the concave curved surface of the transducer head 1 mounted on the rotary holder 12.

In addition, as shown in FIG. 5, the push buttons 16 and 17, the clutch lever 27, and the rotation holder 12 of the switch 15 are all arranged on the same side of the case 11 to improve operability. It is configured to be. On the other hand, the grip 14 is arrange | positioned at the opposite side to these.

In such a scanner, the inspection is performed while the transducer is mounted on the rotary holder 12.

That is, by operating the grip 14 as described above, the scanner is installed in the pipe to be inspected, and then the male brain switch 15 of the scanner is pressed to allow the motor 18 to start the constant speed rotation. This rotation is transmitted to the rotation holder 12 mounted on the U-shaped gear 21e via the gear group 21 and the clutch 22, so that the transducer rotates at a constant speed around the pipe. By transmitting ultrasonic waves from the head 1 of the transducer and receiving the reflected wave, it is possible to inspect the presence or absence of weld defects in the pipe.

In addition, if the clutch lever 27 is rotated as needed during the rotation of the transducer, the clutch 22 is activated to temporarily stop the rotation of the transducer, and the clutch 22 is connected by operating the clutch lever 27 again. Can be rotated again.

In addition, since the scanner is small enough to be operated by one hand, the probe can be rotated around the pipe at a constant speed even when the inspection object is a narrow space, thereby performing an ultrasonic flaw detection. Therefore, the time required for inspection can be shortened, and accurate measurement results can be obtained, thus eliminating the need for a separate inspection function.

In addition, the contact portion between the pipe and the head 1 closely adheres over the radius of the pipe diameter, so that the ultrasonic wave can be efficiently transmitted, and water can be used as the medium. Since water does not leave a trace after use, it is also very suitable for inspection of gas supply piping for semiconductor manufacturing in a clean room of a semiconductor manufacturing plant where high cleanliness is required.

In addition, in a place where the space for the ultrasonic inspection is very narrow, the inspection may be performed manually using only the probe as described above.

That is, the use of the ultrasonic flaw detector according to the present invention minimizes the inspection space, so that pipes disposed near the ceiling and walls in the building can also be inspected.

In addition, by using the ultrasonic flaw detection scanner of the present invention, the flaw detector can be automatically rotated at constant speed around the pipe to perform the ultrasonic flaw inspection. Because of this, the inspection time can be shortened, accurate measurement results can be obtained, and no separate inspection function is required.

In addition, the scanner is compact even in the state of use with the probe, so that ultrasonic inspection in a narrow space can be similarly performed.
