WEAR ELONGATION AMOUNT MEASURING METHOD OF LINK CHAIN AND ITS MEASURING EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide measuring equipment of ware elongation amount of a link chain which can accurately measure wear elongation amount between chain links during operation, not only in the normal time but also in the case deflection is caused in the link chain, and measuring equipment for the method. ;SOLUTION: Tow noncontact system laser displacement gauges 3a, 3b are arranged above a link chain 2. By using the gauges 3a, 3b, an isolation distance as far as the link chain upper surface is continuously measured, and the wear elongation amount between chain links is measured. Measured data are inputted in a CPU 6 serving as a recording means and an operating means with which a CRT is connected, through electric cables 4a, 4b and controllers 5a, 5b. When data indicating deflection of the link chain are contained in the measured results by the laser displacement gauges, data values are corrected in a true chain link length. As a result, it is preferable that a deflection correcting means is installed in the operating means constituting the measuring equipment.;COPYRIGHT: (C)1999,JPO
