A swinging-type apparatus for automatically examining pipes includes first and second clamping devices provided at the ends of an extendible body. The first clamping device is made to clamp a first pipe, the second clamping device is made to unclamp the first pipe, is lifted up away from the first pipe, swung to an adjacent second pipe to be examined, lowered down to the second pipe and made to clamp the same. Next, the first clamping device is made to unclamp the first pipe, is lifted up away from the first pipe, swung to the second pipe, lowered down to the second pipe and made to clamp the same. Sensors provided on at least one of the clamping devices then examine the second pipe. By repeating these operations, the apparatus can be made to travel from one pipe to another to examine a cluster of pipes. The apparatus can also be made to move along a pipe axially thereof by extending and shortening the length of the extendible body.
An automatic pipe examination apparatus for scanning and examining at least one pipe, comprising:
The apparatus according to claim 10, wherein said clamping devices are lifted up and lowered down by rotating a lift shaft and each end of said slidable bodies in opposite directions through identical angles by a motor acting through a spline shaft.
