<p>PROBLEM TO BE SOLVED: To enable a device body to surely reciprocate on a pipe, and to facilitate appropriation to other pipes.SOLUTION: A non-destructive inspection device comprises: a device body 3 that includes a measurement instrument 31 for executing a non-destructive inspection of a pipe 2 and moves on the pipe using traveling wheels 32 arranged in parallel at prescribed intervals; a pair of guide rails 4A and 4B arranged along a pipe axis direction of the pipe, for rolling the traveling wheels 32 by engaging the pair of guide rails with grooves 32a of the traveling wheels 32; and multiple flexible belts 6 that are connected to the pair of guide rails so as to arrange the guide rails in parallel at equal intervals without causing the traveling wheels arranged in parallel at prescribed intervals to run off, are deformed by weight of the device body applied when the device body is placed on the guide rails via the traveling wheels, and are pressed against the pipe in a state of being laid along a peripheral wall of the pipe.</p> |
