Title:
ELEVATOR ROPE TENSION CHECKING DEVICE AND ELEVATOR ROPE TENSION CHECKING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/123650
Kind Code:
A1
Abstract:
The purpose of this invention is to provide an elevator rope tension checking device and an elevator rope tension checking system that can monitor changes in rope tension regardless of car position. An elevator rope tension checking device (18) comprises a storage unit (183), a generation unit (184), and a determination unit (185). The storage unit (183) stores learning data indicating sound or vibration measured during a learning operation by a measuring device (17) that measures the sound or vibration generated when an elevator rope (10) impacts a sheave (3a). The generation unit (184) generates reference data on the basis of the learning data stored in the storage unit (183). The determination unit (185) determines changes in the rope tension on the basis of differences between the reference data and diagnosis data indicating the sound or vibration measured by the measuring device (17) during a diagnosis operation.
