摘要： A wire rope flaw detector includes a magnetizer having a pair of exciting magnets disposed on a back yoke such that polarities thereof are opposite to each other, and forming a main magnetic path in a predetermined segment in an axial direction of a wire rope; and a leakage magnetic flux detection section disposed in the predetermined segment in the axial direction, and detecting leakage magnetic flux generated from a damaged portion of the wire rope. Each of the exciting magnets are formed so as to have a cross-section of a shape that embraces the wire rope when each exciting magnet is cut along a plane perpendicular to the axial direction of the wire rope, and has magnetic orientation, on the cross-section of the exciting magnet, oriented from at least two directions toward the wire rope.

摘要： A wire rope flaw detector comprises a back yoke and excitation permanent magnets, which form a main magnetic path in a predetermined section of a wire rope in the axial direction; a magnetic path member arranged in the predetermined section to be magnetically insulated from the back yoke and the permanent magnets and making the leakage flux generated from a damaged part of wire rope detour to the outside of the wire rope; and a detection coil wound around the magnetic path member for detecting leakage flux. The amount of leakage flux can be increased by providing the magnetic path member and since the windable area of the detection coil is increased, the number of turns of detection coil can be increased.
