JPH028179A - Operation restoring device of after earthquake of elevator - Google Patents

Abstract

PURPOSE:To simplify operation and to shorten a restoring time by flowing current to an automatic restoring coil with the operation of the calling button of the riding spot of the nearest floor and automatically restoring an earthquake sensor, in the title device of the elevator stopped by the earthquake sensor equipped with an automatic restoring coil. CONSTITUTION:When an earthquake sensor A is actuated by a middle scaled earthquake, an elevator is stopped at the nearest floor, e.g., on a 2nd floor. When a 2nd floor riding site button is pushed in this state, a contact 2UBa is closed, a relay 2U is energized, a relay 2HU is energized by the circuit of P-2Ua-2Fb-2HU-N and self-held by a contact 2HUa. The earthquake sensor A is thus restored in a normal state with a restoring coil F being excited by a contact Ba by being energized with a timer T. Consequently a contact Eb is closed and high speed operation circuit H and door control circuit D are restored. By this structure an elevator can be restored in a short time with a simple operation.

認してから正常運転に復帰させている。If a large-scale earthquake occurs while the elevator is in operation and the earthquake sensor is activated, the car is stopped at the nearest floor. After the earthquake, specialized engineers inspected the elevators and confirmed that there were no abnormalities before returning to operation. This recovery method is disclosed in, for example, Japanese Patent Laid-Open No. 55-56967, where a specialized engineer first goes to the machine room and inspects the hoist, governor, control panel, etc. in the machine room to see if there are any abnormalities. Reset the earthquake detector. Climb inside the car, run the car at low speed, and inspect the equipment inside the tower, such as rails, ropes, counterweights, etc., for abnormalities.
If there are no abnormalities, the car is operated at high speed, and after confirming that it is normal, the car is returned to normal operation.

疲労するという問題があった。By the way, in the above return method, after arriving at the building, you first go up the stairs to the machine room on the top floor of the building and inspect the machine room, and then inspect the inside of the tower, so it takes a very long time to return. However, the problem was that specialized engineers were extremely fatigued because they had to restore several elevators in succession on the same day.

本発明は、上記の欠点に鑑みて、比較的地震が小規模の
場合には簡単な操作で、しかも短時間に復帰させる装置
を提供することにある。SUMMARY OF THE INVENTION In view of the above drawbacks, it is an object of the present invention to provide a device that can be operated easily and in a short period of time when an earthquake is relatively small.

〔課題を解決するための手段〕[Means to solve the problem]

この目的は、最寄階に停止している乗り場の乗り場釦を
所定時間押すことにより、地震感知器を自動的に復帰さ
せる装置を設けることにより達成される。This object is achieved by providing a device that automatically resets the earthquake sensor by pressing the platform button of the platform stopped at the nearest floor for a predetermined period of time.
