Abstract: 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.

Abstract: In order to examine abnormality in shape of an outer circumference of a wire rope, the rope tester device includes a comb-shaped detection plate having a curved test edge portion extending along at least one portion of an outer circumference of a substantially circular sectional configuration of the wire rope and a testing recessed portion for receiving the wire rope in the vicinity of or in contact with the test edge portion, and a support device for rotatably supporting the detection plate in the vicinity of or in contact with the wire rope for permitting the rotation of the detection plate when the detection plate receives a force from an abnormal portion of the wire rope to relieve the force. A test string is disposed in an opening of the testing recessed portion for testing a surface that is not in the vicinity of or in contact with the test edge portion.

Abstract: A magnetic flux generated by current excitation is allowed to pass through a part or an entire of a magnetic path of a leakage magnetic flux. A magnetic flux content due to the current excitation is temporally changed to change a leakage magnetic flux content interlinked with a detection coil so that an induced voltage is generated in the detection coil. Consequently, damage can be detected even in a case where there is no relative speed between a wire rope and a wire rope flaw detector. Further, a configuration of the magnetic path and the number of ampere turns of an exciting coil are set to be appropriate to prevent the magnetic flux generated by the current excitation from passing through the detection coil or to allow the magnetic fluxes offset each other. Thus, noise superimposition on the detection coil due to the current excitation can be prevented.

Abstract: 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.

Abstract: There is obtained a wire-rope flaw detector capable of realizing a high signal-to-noise ratio even in the case where only one detection coil is disposed.

Abstract: In order to reduce noise due to the rope vibration in the rope tester, a mounting shaft extending perpendicular to the running direction of the wire rope is positioned in front of the rope tester, and a hook-shaped engagement piece, which extends from the rope tester and is slidable or rotatable into an opened or closed position, is brought into engagement with the mounting shaft so that the rope tester is held movable in the perpendicular direction relative to the running direction of the wire rope.

Abstract: A combined-type coil device provided with a core, a first coil and a second coil, where the core is provided with at least four through holes and the through holes are roughly parallel to one another. When a combination of two through holes constitutes a first through holes pair and the combination of the remaining two through holes constitutes a second through holes pair, a center line passing through the centers of the holes in the first through hole pair and a center line passing through the centers of the holes in the second through hole pair extend almost perpendicular to each other. The first coil passes through the first through hole pair, whereas the second coil passes through the second through hole pair.
