ニット２０の走行車輪を示している。In FIG. 5 (plan view) and FIG. 6 (partially longitudinal front view) showing an enlarged view of the flaw detection main body moving unit 20, the rotating orbit 18 is driven by a drive source 22 such as a DC motor attached to the fixed orbit 17. Driven. Furthermore, a pinion 24 that engages with a rack 23 provided on the fixed track 17 is attached to one side of the flaw detection main body moving unit 20.
A pinion 26 that meshes with a rack 25 provided on the rotating track 18 is mounted on the other side of the flaw detection main body moving unit 20 . In FIG. 6, reference numerals 27 and 28 indicate running wheels of the flaw detection main body moving unit 20.

軌道１８とともに円筒状物体１の周方向に回転される。Therefore, the pinion 26 attached to the flaw detection body moving unit 20 is connected to the unit 20 via the clutch 29.
When locked, the flaw detection main body moving unit 20 is rotated in the circumferential direction of the cylindrical object 1 together with the rotation orbit 18 .

とができる。Next, when the pinion 26 is free to rotate and the pinion 24 is locked to the flaw detection main body moving unit 20 via the clutch 29, the unit 20 is stopped. On the other hand, since the pinion 26 is in a free rotation state, it rotates at that position as the rotation orbit 18 rotates, and the pinion 26 rotates at that position as the rotation orbit 18 rotates.
The probe moving screw 19 is rotated through the probe moving screw 19, and as the probe moving screw 19 rotates, a probe (not shown) moves in the axial direction of the cylindrical object 1. In order to reciprocate the probe in the axial direction of the cylindrical object 1, the rotation of the rotary track 18 can be changed in the forward and reverse directions, or a rotation direction conversion clutch shown at 34 in FIGS. 4 and 5 can be used. By installing it in the flaw detection main body moving unit 2o, it is possible to obtain a trajectory t2 by Y-X scanning as shown in FIG. 7(b).

その効果は下記のとおシである。The present invention is as described above, and in the present invention, a fixed track is attached to the outer peripheral surface of a cylindrical object, a rotating track is attached to the anchor on the fixed track, and a flaw detection main body moving unit is attached to the rotating track. In addition, by installing the drive source for the rotating orbit and the probe moving mechanism outside the rotating orbit system, it is possible to install the driving source for the rotating orbit and the probe moving mechanism outside the rotating orbit system. , which can perform flaw detection on a cylindrical object to be inspected without any trouble,
The effect is as follows.

に富む。In other words, by installing the drive source for the rotating orbit and the probe moving mechanism outside the rotating orbit, it is possible to downsize the flaw detection device that travels around the periphery of a cylindrical object, and compared to the actual machine. When we calculated the dimensions, we confirmed that the size of the flaw detection device could be reduced to about IA compared to the conventional one.
A significant reduction in the height of the device was also confirmed. However,
In particular, in the present invention, the height dimension of the flaw detection device can be significantly shortened, so that the restrictions on the locations where the automatic flaw detection device can be applied are relaxed compared to the past, and the height dimension of the flaw detection device can be significantly reduced. This can improve the application rate of automatic flaw detection equipment, and the drive source with a rotating orbit and separate type can be installed at an appropriate location according to the on-site space situation after flaw detection. , highly maneuverable.

て捌くといった作業を省略することができる。In fact, in the present invention, since the drive source does not move as the flaw detection body moving unit travels, the conventional work of manually handling the cable connected to the drive source can be omitted. I can do it.

電源も１つで事足りる。Furthermore, as in the illustrated embodiment, if the drive source for the rotating orbit and the drive source for the probe moving mechanism are one drive source that is common to both driven bodies, the control system of the flaw detection device can be simplified. Not only can it be made more compact, but it can also reduce its weight.
One power source is sufficient.

道の駆動源と探触子移動機構の駆動源とを、その双方の
被駆動体に共通する１個の駆動源とした自動探傷装置。[Claims] 1. A track attached to the outer circumferential surface of a cylindrical object, a flaw detection main body moving unit that rotates in the circumferential direction of the cylindrical object along the track, and a flaw detection main body moving unit that is attached to the flaw detection main body moving unit and has a cylindrical shape. In an automatic flaw detection device comprising a probe moving mechanism that moves the probe in the axial direction of the object, the trajectory is
Attach a fixed track to the outer circumferential surface of a cylindrical object, and
A rotary orbit is attached to the fixed orbit, a flaw detection body moving unit is further attached to the rotary orbit, and a drive source for the rotary orbit and the probe moving mechanism is installed outside the system of the rotary orbit. Automatic flaw detection equipment. 2. In the invention described in claim 1, an automatic flaw detection device in which the drive source for the rotating orbit and the drive source for the probe moving mechanism are one drive source common to both driven bodies. .
