DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a control device for a hydraulic elevator, and particularly to a control device for a hydraulic elevator that controls a flow rate according to a pattern signal to run a car.

In a system in which the pump discharge t is changed according to the hydraulic elevator r1 pattern to control the running of the car and move the car (for example, the 'N dynamic rock control system, the variable discharge Takura pump control system, etc.), the shock at startup and In order to prevent pregnant sea bream, divide it into a bias pattern that supplies a low flow rate that corrects 6 minutes even at startup and a running pattern, or switch between them, or add 1 to 1 tatami and use pattern i as a samurai, and use this pattern signal. A method for controlling the above-mentioned discharge flow tt' is proposed by

However, in order to compensate for this 6 minutes, a bias pattern that gives a low flow rate by softening is generated. When all 10 paths are started up, large shocks and vibrations may occur depending on the mounting table, negative angle, and oil temperature. If the start-up is done very slowly in order to eliminate shock, the start-up delay n will become very large and the adjustment will be difficult. The control piston is installed between the hydraulic cylinder that drives the motor and the hydraulic pump that supplies pressure oil to this hydraulic cylinder, so that the pressure oil does not flow even if the control piston moves. No dead zone and upper SC control - piston rotation detection device is required.
No. 16 from this rotating and configuring device Change the startup slope of the Sbat turn to make it gentler via the table.
The present invention provides a hydraulic elevator control I4I device it that can suppress a sudden pressure change and suppress the occurrence of a rectangular pattern event and the sea bream shock.

Since the set tonnage pressure v2 is exceeded, the calculation intermediate unit (71) outputs an output %H1, which causes the signal (56b) to become HI.
Then, the sample hold circuit value) holds the output signal (45a) and holds the output as the output signal (37a). At the same time, according to Figure 5 (36b) %HI
Transistor (ONI), resistor (Vtl s
The running pattern signal rises steadily at the time interval of the content (Fig. 10 (gl hoko teru), adder 18), so both ministries add f, and according to the signal of Fig. 10 (h), the electric sea bream is 08.
), the flow rate is increased by this pattern, so the piston (61A) moves to the cylinder and gives the flow rate (6

At this time, since the contact (41D't+) of the electromagnetic relay (Vl i #I) shown in Figure 6 is open, the +afiH (lower) lowering coil (11b) is connected to the ) The dance does not move 1 0 Regular pattern When the voltage and pressure are saturated, the car pressure becomes constant, and the car (51) becomes a constant series. When the car (5) rises to the east and reaches the deceleration point, The cam (8) is held at the 1st position (9) and outputs %H' No. 18 to % (9a), so it is 1 time tI
At I, the transistor (102) in Fig. 5 turns on (and the Zener diode (101) &'L limit decreases to a running pattern, and becomes short at the limit voltage of the Zener diode (101). When the vehicle travels to the stop command point, the normally closed contact (10'b) opens at time t, and the closed contact (30T) demagnetizes, so the normally open contact (30T) opens.
c) By opening, the output of the fifth worst NOT game (104) becomes -HI and the transistor (103) turns on, and the voltage goes through the gates ((5)) and (5). Time 16). At this time, 11! In the pattern voltage of L motor (18J), there is only the voltage that is held at (37a), and this pattern voltage H-j is also the motor rotation speed that is fully corrected for 1 minute, and (5) is the voltage that is held without running. It remains stopped.
