A wire rope inspection system comprising:
- an excitation unit configured to apply a magnetic flux to a wire rope that is an inspection target;
- a detection unit configured to detect a magnetic flux of the wire rope to which the magnetic flux has been applied by the excitation unit;
- a detachable unit configured to be detachably mounted on a stationary unit fixed in proximity to the wire rope, the detachable unit being provided with at least the detection unit;
- and
- a positioning mechanism configured to position the detachable unit with respect to the stationary unit such that the detection unit is arranged at a predetermined position with reference to the wire rope,
- wherein the excitation unit is arranged at the detachable unit together with the detection unit, and
- wherein the stationary unit includes a magnetic field application unit for aligning a magnetization direction of the wire rope by applying a magnetic field in advance with respect to the wire rope.
A positioning method for a wire rope inspection system, comprising the steps of:
- attaching a positioning jig configured to adjust a relative position of a stationary unit fixed in proximity to a wire rope that is an inspection target with respect to the wire rope such that a detection unit configured to detect a magnetic flux of the wire rope is arranged at a predetermined position with reference to the wire rope;
- setting a positioning mechanism configured to position a detachable unit with respect to the stationary unit by adjusting a position of the stationary unit such that the positioning jig is arranged along the wire rope, the detachable unit being provided with at least a detection unit and being configured to be detachably attached to the stationary unit;
- and
- positioning the detachable unit with respect to the stationary unit by the positioning mechanism by which the detachable unit has been positioned by attaching the detachable unit to the stationary unit to detect the magnetic flux of the wire rope by the detection unit.
