摘要： 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.
摘要翻译：通过电流激励产生的磁通被允许通过漏磁通的磁路的一部分或全部。暂时改变由电流激励引起的磁通量，以改变与检测线圈相互连接的漏磁通量，从而在检测线圈中产生感应电压。因此，即使在钢丝绳和钢丝绳缺陷检测器之间没有相对速度的情况下也可以检测到损坏。此外，励磁线圈的磁路和安匝数的配置被设置为适合于防止由电流激励产生的磁通量通过检测线圈或允许磁通量相互抵消。因此，可以防止由于电流激励引起的对检测线圈的噪声叠加。

摘要： 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.

摘要： 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.
