ELEVATOR BALANCE COEFFICIENT DETECTION METHOD AND DETECTOR THEREFOR

摘要

An elevator balance coefficient detection method and a detector therefor. The detection method comprises the steps of: an electric energy detection device (5) accessing a power line of an elevator drive motor; a speed detection device (7) accessing an operating mechanical transmission member of an elevator car (3); measuring and recording in real time the speed data and the drive motor power data of the car (3) when the car (3) and a counterweight run to the same horizontal location; obtaining the balance coefficient value through calculation based on the elevator structure principle and the energy transfer relationship during running by applying the abovementioned data and the basic parameter of the elevator to be measured. The detector comprises an elevator data acquisition system and a detection data processing system. The electric energy thereof is measured by an AC broadband power measurement device, and the speed thereof is measured by a wire rope displacement measurement device using a photoelectric mouse chip or by a tachometer type speed measurement device.
