WIRE ROPE INSPECTING DEVICE FOR ELEVATOR, AND ROPE OUTER DIAMETER MEASURING METHOD

摘要

PROBLEM TO BE SOLVED: To actualize highly reliable maintenance work by easily and accurately measuring the outer diameter of an elevator wire rope over its total length and inspecting the distribution of the outer diameter.;SOLUTION: A light projecting part 11 is installed on a feed passage for the wire rope 3 to be inspected for emitting an optical beam from a laser light source, and a light receiving part 12 having a light receiving element 12a for receiving the optical beam from the light projecting part 11 is installed in opposition to the light projecting part 11 across the wire rope 3 for outputting a signal depending on the light receiving condition. A control part 13 is used for emitting the optical beam from the laser light source of the light projecting part 11 while giving feeding operation to the wire rope 3 and for measuring the outer diameter of the wire ripe 3 in accordance with an output signal from the light receiving part 12 receiving the optical beam.;COPYRIGHT: (C)2008,JPO&INPIT
