Abstract
A wire rope inspection device (100) is provided with a first detection coil (30) and a second detection coil (40), and a processing unit (61). The second detection coil is arranged to be inclined to the first detection coil when viewed from a direction (X-direction) perpendicular to a first direction (Z-direction) along which the first detection coil moves relative to the wire rope (W). The processing unit identifies an abnormality position of the wire rope in the first direction based on a detection signal detected by the first detection coil and identifies an area of the abnormality position of the wire rope in a cross-section based on a detection signal detected by the second detection coil.
Claims16
A wire rope inspection device comprising:
- a plurality of detection coils each configured to move relative to a wire rope in a direction along which the wire rope extends and detect magnetic flux of the wire rope;
- and
- a processing unit configured to acquire and process detection signals detected by the plurality of detection coils,
- wherein the plurality of detection coils includes a first detection coil and a second detection coil, the first detection coil being provided along a circumference direction of the wire rope, the second detection coil being provided along the circumference direction of the wire rope and arranged to be inclined to the first detection coil when viewed from a direction perpendicular to a first direction along which the first detection coil moves relative to the wire rope, and
- wherein the processing unit is configured to
- identify an abnormality position of the wire rope in the first direction based on a detection signal detected by the first detection coil and
- identify an area of the abnormality position of the wire rope in a cross-section of the identified abnormality position of the wire rope in the first direction, based on a detection signal detected by the second detection coil.
