Abstract:
Provided is a wire rope flaw detector including a magnetizer configured to form a main magnetic flux in a part of a wire rope in a longitudinal direction thereof. A plurality of search coils are configured to detect a leakage flux that occurs from a damaged part of the wire rope in a segment in which the main magnetic flux is formed. A control unit is configured to detect induced voltages generated in the plurality of search coils. Further, the control unit is configured to superimpose voltage waveforms of the plurality of search coils on one another while shifting the voltage waveforms by a time calculated based on an interval between the plurality of search coils adjacent to each other and on a relative moving speed of the wire rope with respect to the magnetizer, to thereby amplify a peak of the induced voltage.

Claim (Index 3):
A wire rope flaw detector comprising:\n a magnetizer, which is configured to form a main magnetic flux in a part of a wire rope in a longitudinal direction of the wire rope; a plurality of search coils, which are arranged with an interval so as to be spaced apart from one another in the longitudinal direction of the wire rope, and are configured to detect a leakage flux that occurs from a damaged part of the wire rope in a segment in which the main magnetic flux is formed; and a control unit, which is configured to detect induced voltages generated in the plurality of search coils, wherein: the control unit is configured to superimpose voltage waveforms of the plurality of search coils on one another while shifting the voltage waveforms by a time calculated based on an interval between the plurality of search coils adjacent to each other and on a relative moving speed of the wire rope with respect to the magnetizer, to thereby amplify a peak of the induced voltage; the plurality of search coils are connected to one another in series in order in terms of a moving direction of the wire rope; and the control unit is configured to store V(t) for a fixed time period, and to use, as an evaluation index S(t) of whether or not the damaged part exists, the following expression: S \ue8a0 ( t ) = \u2211 k = 1 m \ue89e V ( t - P v \ue89e ( k - 1 ) ) where V(t) represents a voltage generated between terminals of ones of the plurality of search coils that are located at both ends of the wire rope in the moving direction, each of the terminals being not connected to an adjacent one of the plurality of search coils, m being an integer equal to or larger than 2 represents a number of the plurality of search coils, P represents an installation interval of the plurality of search coils, and v represents the relative moving speed of the wire rope with respect to the magnetizer.
