Abstract

본 발명은 유압엘리베이터의 제어장치에 관한 것으로, 인버터 고장이 발생한 경우 유량밸브제어부가 동작하기 전에 유도전동기의 전원이 먼저차단되기 때문에 순간적으로 실린더측 압력과 펌프측 압력의 압력차에 의해 카의 쇼크를 유발시키는 문제점이 있었다, 본 발명은 이러한 종래의 문제점을 해결하기 위해 입력전압이 정류되어 인가되면 이를 펄스폭 조절하여 유도전동기에 인가하는 인버터와; 고장이 발생하면 유압밸브 및 인버터를 제어하여 카를 정지시키는 속도제어반으로 구성된 유압엘리베이터에 있어서, 상기 속도제어반은 엘리베이터의 일반적인 고장을 검출하는 비상고장검출수단과; 인버터의 고장을 검출하는 인버터고장검출수단과; 인버터의 고장을 미리 예측하는 인버터고장감시수단과; 상기 비상고장검출수단과 상기 인버터고장검출수단과 상기 인버터고장감시수단의 출력 신호에 따라 유량밸브 및 인버터를 제어하여 카의 운전을 제어하는 제어수단으로 구성한 유압엘리베이터의 제어장치를 창안한 것으로 이와같이 인버터의 고장을 검출하는 인버터고장검출부의 검출기준레벨보다 낮은 레벨로 설정된 인버터고장감시부를 설치하여 인버터의 고장이 예측되면 미리 밸브제어신호를 출력 하도록 함으로써 밸브개폐시간과 인버터의 출력신호 차단시간이 같아지게 되어 카를 안정되게 정지시킬 수 있는 효과가 있다.The present invention relates to a control apparatus for a hydraulic elevator, in which, when an inverter failure occurs, the power source of the induction motor is first cut off before the flow valve control unit is operated, so that the shock of the car is instantaneously caused by the pressure difference between the cylinder- In order to solve such a conventional problem, the present invention has an inverter for regulating an input voltage and applying a pulse width to the induction motor when the input voltage is applied. And a speed control panel for controlling the hydraulic valve and the inverter to stop the car when a failure occurs, the speed control panel comprising: emergency failure detection means for detecting a general failure of the elevator; An inverter failure detecting means for detecting a failure of the inverter; Inverter failure monitoring means for predicting a failure of the inverter in advance; And control means for controlling the operation of the car by controlling the flow rate valve and the inverter in accordance with the output signals of the emergency failure detecting means, the inverter failure detecting means, and the inverter failure monitoring means. In this way, An inverter failure monitoring section set at a level lower than the detection reference level of the inverter failure detecting section for detecting a failure of the inverter is provided so that the valve control signal is outputted in advance when the failure of the inverter is predicted so that the valve opening / So that the car can be stably stopped.
