Description

유압 엘리베이터Hydraulic elevator

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본원 발명에 의한 유압엘리베이터의 일실시예를 나타낸 개념도, 제2도는 제1도의 유압엘리베이터의 요부 전기회로도.1 is a conceptual diagram showing an embodiment of a hydraulic elevator according to the present invention, Figure 2 is a main circuit diagram of the hydraulic elevator of FIG.

Claims (1)

개폐밸브를 개방하여 유압잭의 압유를 배출하여 케이지를 하강시키고, 또한 유압펌프를 전동기에 의해 구동하여 상기 개페밸브로부터의 배출압유의 유량을 제어하여 상기 케이지의 하강동작을 제어하는 유압엘리베이터에 있어서, 상기 개페밸브 및 유압펌프 사이의 관로압력을 검출하는 압력검출기와, 이 압력검출기를 통해서 상기 관로압력이 소정치 이하로 되었을때에, 상기 전동기를 소세시키는 이상제어장치를 구비한 것을 특징으로 하는 유압엘리베이터.In the hydraulic elevator to open and close the valve to discharge the hydraulic pressure of the hydraulic jack to lower the cage, and to drive the hydraulic pump by an electric motor to control the flow of the discharge pressure oil from the open valve to control the lowering operation of the cage, And a pressure detector for detecting the pipeline pressure between the open valve and the hydraulic pump, and an abnormality control device for flushing the electric motor when the pipeline pressure becomes below a predetermined value through the pressure detector. elevator. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
