本発明は油圧エレベータの制御装置に係り、作
動油の温度低下によつてアンロード運転を行なう
ものに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control device for a hydraulic elevator, and more particularly, to one that performs unloading operation by lowering the temperature of hydraulic oil.

転防止タイマーが動作し、エレベータが動けなく
なつてしまう。 The viscosity of hydraulic fluid in hydraulic elevators changes with temperature changes. Therefore, when the oil temperature decreases, it has a significant negative effect on the speed characteristics, causing a decrease in performance such as a decrease in landing speed and landing error. As a way to deal with this, unloading operation is performed. Conventional unloading operation is a continuous operation until the oil temperature detection output disappears, and if the oil temperature rises within a certain period of time and the detection output does not disappear, the safety device's anti-slip timer is activated and the elevator becomes unable to move. I end up.
本発明の目的は、上記欠点をなくし、アンロー
ド運転も空転防止タイマーも正規の動作をさせ、
かつ運転不能による運転効率の低下を防止すると
ころにある。 The purpose of the present invention is to eliminate the above-mentioned drawbacks, to enable normal operation of unloading operation and idle rotation prevention timer,
It also prevents a decrease in operating efficiency due to inoperability.
本発明の特徴は、油温低下時におけるアンロー

め、再度アンロード運転を行ない、一定の油温に
達するまで断続運転させるところにある。 A feature of the present invention is that the unloading operation when the oil temperature drops is stopped at a time when the idle prevention timer does not operate, and the unloading operation is performed again, and the unloading operation is continued intermittently until the oil temperature reaches a certain level.

まで繰返す。 The figure shows a circuit showing an embodiment of the present invention, with P,
N is the elevator power supply, Y is the oil temperature detection contact, A is the unload operation command relay, A 1 and A 2 are the contacts,
M is a motor rotation command relay, TA is an unload operation timer, TM 1 and TA 2 are its contacts, TB is an unload stop timer, and TB 1 is its contact. Next, the operation of the embodiment of the present invention will be described. When the oil temperature drops to a certain point, contact Y turns on, relay A turns on, and contact A1 turns on relay M, which rotates the motor and starts unloading operation. At the same time, timer TA starts counting through contact A2 . This timer TA is set to a shorter time limit than the idle prevention timer, and when the set time limit is reached, the timer TA turns on and its contacts
TA 2 turns OFF, relay M turns OFF, and the motor stops. Also, timer TB starts counting by contact TA 1 . Timer when reaching any time
TB turns ON, its contact TB 1 turns OFF, and timer TA
is turned OFF, contact TA 2 is ON, relay M is ON, the motor rotates, and unloading operation starts again.
Repeat the above operation until the oil temperature rises and contact Y turns OFF.
