Wire rope flaw detector and method for adjusting wire rope flaw detector

摘要

Provided is a wire rope flaw detector, which is capable of improving detection accuracy for a wire rope breakage by keeping an interval between a wire rope to be subjected to a measurement and an adjacent wire rope. The wire rope flaw detector includes: a magnetizer, which is configured to form a main magnetic path in a predetermined set interval of a wire rope in an axial direction of the wire rope; a detection coil, which is arranged in the predetermined set interval so as to be magnetically insulated from the magnetizer and is configured to detect a leakage magnetic flux generated by a damage portion of the wire rope; and position restricting mechanisms, which are configured to keep an interval between the wire rope passing through the detection coil and a wire rope adjacent to the wire rope passing through the detection coil.
