| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an elevator device comprising a governor for detecting overspeed during drop operation, and transmitting rotation of a sheave to the governor via a cam type one-way clutch, capable of preventing the governor from detecting drop overspeed by error, during raise operation, or, capable of suppressing impact from being applied to the governor when transiting to the drop operation.SOLUTION: The elevator device of the present invention comprises a rotation inhibition mechanism for, inhibiting a rotary body of the governor from rotating, when transmission of the rotation of the sheave to the governor is released, during raise operation.SELECTED DRAWING: Figure 1
【課題】下降運転時の過速度を検出する調速機を備え、カム式ワンウェイクラッチを介して綱車の回転を調速機に伝えるようにしたエレベータ装置において、上昇運転時、調速機が誤って下降過速度を検出するのを防止し、または、下降運転に移行する際に調速機に衝撃が加わるのを抑制する。【解決手段】本発明のエレベータ装置は、上昇運転時など調速機への綱車の回転が伝達解除された時、調速機の回転体が回転することを阻止する回転阻止機構を有する。【選択図】 図１ |
