Port enters the B mouth of the first driving hydraulic cylinder 16, the second driving hydraulic cylinder 17, meanwhile, the oil circuit of branch all the way of high-pressure medium into
Enter second mouthful to shuttle valve 15, then finally enter the control port of hydraulic control one-way valve 5 by third mouth, by the inverse of hydraulic control one-way valve 5
Only function is closed.At this point, the first valve 12 and the second valve 13 opening are connected to, high-pressure medium is by the first driving hydraulic cylinder 16, the
The A mouth of two driving hydraulic cylinders 17 returns to the second chamber 25 and the of synchronized cylinder 2 by the first valve 12 and the second valve 13 respectively
Four chambers 27.The first chamber 24 of synchronized cylinder 2 is connected to two four by the hydraulic control one-way valve 5 that return-stopping function fails with third chamber 26
The port A of three-way electromagnetic valve 4, at this point, the port B of two-position four-way solenoid valve 4 is connected to the port P, the end A of two-position four-way solenoid valve 4
Mouth is connected to T-port.So high-pressure medium directly returns the fuel tank of hydraulic power source 6 through two-position four-way solenoid valve 4, pressure also disappears therewith
It loses.And enter synchronized cylinder 2 second chamber 25 and the 4th chamber 27 pressure medium be greater than synchronized cylinder 2 24 He of first chamber
The pressure medium that third chamber 26 flows out, the body of rod 21 of synchronized cylinder 2 move from right to left, and the first driving hydraulic cylinder 16 and second is driven
The piston rod of hydrodynamic cylinder pressure 17 is begun to decline, after falling into place, the work of the first driving hydraulic cylinder 16 and the second driving hydraulic cylinder 17
Stopper rod is fully retracted.Finally, the side a electromagnet power loss of three position four-way electromagnetic valve 1, spool return to normal position, P is shut, high-pressure medium
It is disconnected, the first valve 12 and the second valve 13 are closed and disconnected, thus by the first driving hydraulic cylinder 16 and the second driving hydraulic cylinder
17 A mouth is fully disconnected with the second chamber 25 of synchronized cylinder 2 and the 4th chamber 27, and the body of rod 21 of synchronized cylinder 2 also completely arrives at a left side
Side pole limit.
After after many tests, the Derivative limit on the left or on the right position of synchronized cylinder 2 and the first driving hydraulic cylinder 16 and the second driving hydraulic cylinder
17 high and low position is corresponding, and forms fixed matching relationship.Consider the problems such as letting out in pipeline oil leak or driving hydraulic cylinder
Cause positional relationship disorder, the difference of necessarily the first driving hydraulic cylinder 16 and the second driving hydraulic cylinder 17 that rear extended meeting occurs
Step.For this purpose, carrying out location position automatically when the first driving hydraulic cylinder 16 and the second driving hydraulic cylinder 17 are in low level, guarantee
The synchronism of first driving hydraulic cylinder 16 and the second driving hydraulic cylinder 17.The same flushing process of calibration process, only first by synchronized cylinder 2
The body of rod 21 limit on the left position is pushed by a left side, then be back to limit on the right-right-hand limit position from limit on the left position.
For example, the utility model hydraulic synchronization control device can be used for controlling the lifting of intermediate tundish carriage, hydraulic synchronization control
After device manufacturing processed, pressure test and performance test need to be carried out, is installed on intermediate tundish carriage after test passes, simultaneously
First driving hydraulic cylinder 16 and the second driving hydraulic cylinder 17 will be installed as requested, and carry out external hydraulic power source 6 and hydraulic synchronization
Control device and hydraulic synchronization control device to the pipeline between the first driving hydraulic cylinder 16, the second driving hydraulic cylinder 17 connect
It connects.The flushing and pressure testing that progress pipeline is needed before use, need to debug power, the output pressure etc. for confirming external hydraulic power source 6.It is synchronous
The Derivative limit on the left or on the right position of cylinder 2 is corresponding with the upper level position of the first driving hydraulic cylinder 16, the second driving hydraulic cylinder 17, and in synchronization
Limit switch is installed in the Derivative limit on the left or on the right position of cylinder 2, and to monitor the first driving hydraulic cylinder 16, whether the second driving hydraulic cylinder 17 arrives
Position.Initial position is set to driving hydraulic cylinder and is in low level (hydraulic cylinder piston rod fully retracted state).Operate electrical control
Panel, presses " rising " button, the side the b electromagnet of three position four-way electromagnetic valve 1 and the side the b electromagnet of two-position four-way solenoid valve 4 obtain it is electric,
First valve 12, the second valve 13 open connection after being delayed 2 seconds.High-pressure medium passes through three position four-way electromagnetic valve 1,3 He of pressure reducing valve
Two-position four-way solenoid valve 4 and hydraulic control one-way valve 5 enter the first chamber 24 and third chamber 26 of synchronized cylinder 2, push and synchronize
2 piston of cylinder moves from left to right, at this point, the oil liquid in second chamber 25 and the 4th chamber 27 is due to first chamber 24 and third
The extruding of chamber 26 produces the pressure of same load matched, opens to the A mouth of the first driving hydraulic cylinder 16, the second driving hydraulic cylinder 17
Beginning fuel feeding, two driving hydraulic cylinders start synchronous rising, and when rising to nominal position, corresponding synchronized cylinder 2 also runs to one
Position can mark as A, at this time limit switch sender, three position four-way electromagnetic valve 1,4 power loss of two-position four-way solenoid valve,
One valve 12, the second valve 13, which are closed, to be disconnected, the locking of driving hydraulic cylinder position.Electrical control panel is operated, " decline " button is pressed,
First valve 12 is connected to the second valve 13 opening, and the side a electromagnet of three position four-way electromagnetic valve 1 is delayed 2 seconds electric.High-pressure medium
The B mouth that driving hydraulic cylinder is entered by three position four-way electromagnetic valve 1, sets up corresponding pressure quickly, at the same time, divides all the way
Branch enters second mouthful of shuttle valve 15, and is delivered to third mouth by the second oral instructions, finally reaches the control port of hydraulic control one-way valve 5,
The return-stopping function of hydraulic control one-way valve 5 is closed, the medium of the first driving hydraulic cylinder 16 and the second driving hydraulic cylinder 17 is through the first valve
The 12, second valve 13 of door enters the second chamber 25 and the 4th chamber 27 of synchronized cylinder 2, pushes the body of rod 21 of synchronized cylinder 2 by the right side
It moves downward, the first chamber 24 of synchronized cylinder 2 and the medium of third chamber 26 are through hydraulic control one-way valve 5 and two-position four-way solenoid valve 4
The fuel tank of hydraulic power source 6 is flowed into afterwards, and the first driving hydraulic cylinder 16 starts synchronous decline with the second driving hydraulic cylinder 17, falls into place
Afterwards, synchronized cylinder 2 also runs to the extreme position in left side, is labeled as position B, at this time limit switch sender, three position four-way electromagnetic valve 1
Power loss, the first valve 12 and the second valve 13, which are closed, to be disconnected, the first driving hydraulic cylinder 16 and 17 position of the second driving hydraulic cylinder lock
It is fixed.
