Elevator apparatus

Abstract

The present invention provides an elevator apparatus, capable of being controlled to run when there is an earthquake even though a detector used in common is fault. A first (used under normal condition) detector is arranged in an elevator car running in a lifting channel, a first (used under normal condition) parking position detecting body is arranged on a parking position of the elevator car onthe lifting channel side in a projecting manner such that the first detector detects the parking position of the elevator car when it faces to the first detector. In the elevator apparatus capable ofbeing controlled to run by an earthquake detector when there is an earthquake, a second (used under emergent condition) wide detector is arranged in the elevator car, and a second (used under emergent condition) parking position detector is arranged on a position facing to the second detectoron the lifting channel side, when the earthquake detector plays a function of switching so as to use the second detector in control.

Description

technical field [0001] The present invention relates to an elevator system that can operate safely even when an earthquake occurs. Background technique [0002] An elevator usually consists of an elevator car, a counterweight, a main sling, a sling for balancing, and a tail cable. In the elevator with the above structure, the longer the lifting stroke of the elevator, the greater the lateral shaking of the building when earthquakes and strong winds have taken place, especially in buildings with flexible structures such as super high-rise buildings. During earthquakes and strong winds, the building will shake a lot laterally, which will cause a lot of long strip objects such as various slings and tail cables to shake greatly. As a result, the elongated objects may come into contact with various equipment in the elevator passage, and the equipment in the elevator passage may be damaged when the elongated objects come into contact with the equipment in the elevator passage. ...

AI Technical Summary

Problems solved by technology

But when the detector that detects the parking position of the predetermined parking floor of the elevator car is damaged, if the situation that the detector is damaged is not detected, although the elevator car still travels or decelerates to a stop, it cannot be confirmed whether Stopped at the target floor, so there may be a problem that the elevator door may not be opened, resulting in passengers being locked in the elevator car
