Abstract

유압엘리베이터의 상승운전시의 개폐밸브의 압력손실을 작게해, 하강운전시 정전이 되어도 카를 단거리로 정지할 수 있도록 한다.The pressure loss of the shut-off valve during the up and down operation of the hydraulic elevator is reduced, so that the car can be stopped for a short distance even in the event of a power failure during the down operation.

카(2)의 상승시는 제1개폐밸브(5)를 폐지하고, 제2개폐밸브(21)를 개구해서 유압펌프(3)가 토출하는 압유를 유압잭(1)에 송출해서 카(2)를 상승시킨다.When the car 2 rises, the first opening / closing valve 5 is closed, the second opening / closing valve 21 is opened, and the hydraulic oil discharged from the hydraulic pump 3 is sent to the hydraulic jack 1 to release the car 2. Raise.

하강시는 제2개폐밸브(21)를 폐지하고, 제1개폐밸브(5)를 개구해서 유압잭(1)의 압유를 유압펌프(3)를 제어해서 유조(8)로 배출한다.At the time of the lowering, the second opening / closing valve 21 is closed, the first opening / closing valve 5 is opened, and the hydraulic oil of the hydraulic jack 1 is controlled to discharge the oil to the oil tank 8.

제1개폐밸브(5)는 하강전용이기 때문에 그 개도는 상승운전과는 관계없이 작게 설정할 수 있다.Since the first opening / closing valve 5 is exclusively for lowering, the opening degree can be set small regardless of the rising operation.

제2개폐밸브(21)의 밸브체(21b)는 압유의 유량에 대응한 개도가 되기 때문에 정전으로 압유의 흐름이 정지하였을때 신속하게 폐지한다.Since the valve body 21b of the second opening / closing valve 21 becomes an opening degree corresponding to the flow rate of the pressurized oil, it is promptly closed when the flow of the pressurized oil stops due to electrostatic power.
