傷装置。[Scope of Claim for Utility Model Registration] A flaw detection device for existing pipes, in which a sensor B for flaw detection on the pipe is attached to a main body A that is movable within the pipe using a pulling tool or a pressing tool, wherein the main body A is:
A pair of front and rear holding bodies 2a, 2b, these holding bodies 2a
, 2b, and
It consists of a large number of elastic strips 5, 6 attached to the holder 2a or 2b and arranged around the flexible object 3, with one end 5a, 6A of each of the elastic strips 5, 6 attached to the holder 2a or 2b. and the other end 5b, 6b is inserted into a recess 7 formed in the other 2b or 2a of the holding body so that the length can be changed freely.
A flaw detection device for an existing conduit, in which each of the pipes is curved so that the middle side in the longitudinal direction protrudes in the radial direction of the pipe. Both ends 5 of the elastic strips 5 and 6 are located closer to the longitudinal intermediate portions 5c and 6c, which are disposed so as to be integrally displaceable near the outer side with respect to the flaw detection sensor B.
The flaw detection device according to claim 1, wherein a, 5b or 6a, 6b are formed in a tapered shape.
