Title: Power interruption-time rescue operation device for elevator
Inventor: OGAWA YUTAKA
IPC: B66B5/02
Filed: 1989-04-03
Abstract: PURPOSE:To more improve service for passengers by performing rescue operation after the predetermined rest time in case of judging an earthquake in a small scale in accordance with an earthquake detecting level. CONSTITUTION:In a condition that contacts 17b2, 16b are closed without generation of an earthquake, when a power interruption-detecting relay 12b is closed by power interruption, a rescue operation relay 11 is energized performing rescue operation. Now an earthquake is generated, when a specific low earthquake-detecting relay 21 is closed, the rescue operation is suspended by energizing a specific low detecting relay 15 and a specific low earthquake- detecting keep relay 17 and deenergizing the relay 11. At this time, under a condition starting a specific low standby timer 18, deenergizing a set signal creating relay 19 with a time delay of RC time constant (for instance, one minute) and a specific low reset relay 20, resetting a seismometer to the specific detection, opening the contact 21 and resetting the relay 15, when the timer 18 reaches a time limit, the rescue operation is restarted. On the contrary, when a low earthquake detecting contact 22 is closed, the rescue operation is suspended.
