Elevator governor and elevator apparatus using the same

摘要

A governor for an elevator includes a drive wheel which is driven to rotate in accordance with ascent and descent of an elevator body, and rotation of the drive wheel is transmitted to the first rotary body, and based on the rotation speed of the first rotary body, A first speed adjusting mechanism for detecting an ascending overspeed, a rotation speed of the driving wheel is transmitted to the second rotating body via the clutch when the lifting body is descending, and based on the rotation speed of the second rotating body A second speed adjusting mechanism that detects a descending speed of the elevating body and detects transmission of the rotation of the driving wheel by the clutch when the elevating body ascends, a first roller that rotates in synchronization with the clutch, A second roller disposed opposite to the first roller, and a belt wrapped around the first roller and the second roller, and the tension of the belt prevents rotation of the clutch when the elevating body is ascended A rotation prevention mechanism for detecting abnormality of the belt, and abnormality detection means , Comprising a.
