发明名称 DAMPING DEVICE AND METHOD FOR HYDRAULIC ELEVATOR
摘要 PURPOSE:To reduce sink/float quantity at landing, shock at starting, and vibration at running of a passenger cage so as to improve safety, easy handling, and comfortability of a hydraulic elevator, by controlling the pressing force of a sliding piece according to a control signal from a position detector and the like. CONSTITUTION:An electromagnetic mechanism 21 is actuated with a controller 9, based on electric signals from position detectors 16, 24 and weighing equipments 17, 25, and the pressing force of a sliding piece 20 against a guide rail 23 is varied according to variation of a superimposed load at landing or starting of a passenger cage. Hereby, sink/float quantity at landing and shock at starting of the passenger cage 15 are reduced. Sequentially, vibrational quantity of the passenger cage at running condition is measured with a vibrometer 18 and the electromagnetic mechanism 21 is actuated with the controller 9 based on this signal, the pressing force of the sliding piece 20 against the guide rail 23 is controlled, and the vibration of the passenger cage 15 at running condition can be reduced.
