Mouthful B1 is interconnected, the second rod chamber hydraulic fluid port B2 of oil cylinder b6 respectively with the control port C1 of balanced valve 2 and solenoid directional control valve 1
Second work oil outlet B is interconnected；The piston rod terminal of oil cylinder a5 installs position sensor a7, and the piston rod of oil cylinder b6 is whole
End installation position sensor b8；Check valve 9 is installed between the oil inlet and oil outlet of balanced valve 2；The rodless cavity of oil cylinder b6
Volume slightly larger than oil cylinder a5 rod chamber volume.
The oil cylinder a5 and oil cylinder b6 is connected in series.
The solenoid directional control valve 1 is three-position four-way valve.
The electromagnetic switch valve 3 is 2/2-way valve.
The oil inlet of the check valve 9 is connected to the oil inlet of balanced valve 2, oil outlet and the balanced valve 2 of check valve 9
Oil outlet connection.
The model AZ8104 of the position sensor a7 and position sensor b8.
The parameter of the oil cylinder a5 are as follows: internal diameter of cylinder 70mm, diameter of piston rod 40mm, stroke 380mm.
The parameter of the oil cylinder b6 are as follows: internal diameter of cylinder 57.5mm, diameter of piston rod 30mm, stroke 380mm.
This is used for the light loading cylinders synchronization system of antenna array, is suitable for vehicle radar antenna front weight at one tonne
The expansion and folding of following antenna array.During the antenna array synchronous expansion and gathering, need to guarantee two oil cylinders
Synchronous operation, the embodiment of the present invention is by the way that oil cylinder a5 and oil cylinder b6 to be together in series, so that oil cylinder a5 and oil cylinder b6 are moved through
Cheng Zhong can export the oil liquid in the first rod chamber of oil cylinder a5 to the second rodless cavity of oil cylinder b6, in synchronous stretching process
In, it is contemplated that the practical foozle of oil cylinder and the interior of oil cylinder are let out, and the oil liquid volume of the first rod chamber of oil cylinder a5 is made and is omited
The oil liquid volume of the second rodless cavity less than oil cylinder b6, when oil cylinder a5 it is fully extended in place after, there are also smaller strokes by oil cylinder b6
It is not fully extended in place, to eliminate this error, fully extended oil cylinder a5 in place touches the position sensing of its piston rod terminal
Device a7, it is electric that sending instruction obtains electromagnetic switch valve 3；The high pressure oil that solenoid directional control valve 1 exports continues to press on oil cylinder b6 and reaches end
Point touches the position sensor b8 of oil cylinder b6 piston rod terminal, issues instruction and allows 3 power loss of electromagnetic switch valve, completes described two
The synchronous of oil cylinder is stretched out.Similarly, during synchronous, it is contemplated that the practical foozle of oil cylinder and the interior of oil cylinder are let out, by
In the oil liquid volume of first rod chamber of the oil liquid volume slightly larger than oil cylinder a5 of the second rodless cavity of oil cylinder b6, when oil cylinder a5 is complete
After shrinking in place, that there are also smaller strokes is not fully extended in place by oil cylinder b6, and to eliminate this error, the second of oil cylinder b6 is without bar
Intracavitary extra oil liquid is discharged by safety valve, completes the synchronous of described two oil cylinders.
The specific work process for being used for the light loading cylinders synchronization system of antenna array is as follows:
1) stretch out operation: the stretching electromagnet DT1 of solenoid directional control valve 1 obtains electric, and high pressure oil enters solenoid directional control valve by oil inlet P
1 the first actuator port A, high-pressure oil flow reach the first rodless cavity hydraulic fluid port A1 of oil cylinder a5 through check valve 9, drive cylinder a5's
Piston rod stretches out, and the oil liquid in the rod chamber of oil cylinder a5 is flowed out by the first rod chamber hydraulic fluid port A2 of oil cylinder a5, until oil cylinder b6
The piston rod of second rodless cavity hydraulic fluid port B1, drive cylinder b6 stretches out, the oil liquid in the rod chamber of oil cylinder b6 pass through oil cylinder b6 the
Two rod chamber hydraulic fluid port B2 outflow, until the second actuator port B of solenoid directional control valve 1 flows out to oil return inlet T.
In general, the volume of the second rodless cavity of oil cylinder b6 should phase with the volume of the first rod chamber of the oil cylinder a5
Deng, present invention applicant in view of practical foozle and the interior of oil cylinder let out situation, by the volume of the first rod chamber of oil cylinder a5
Production is slightly less than the volume of the second rodless cavity of oil cylinder b6, in this way, when the piston rod of oil cylinder a5 is fully extended, the work of oil cylinder b6
Stopper rod is not there are also a little stroke is fully extended, to eliminate this error, touches the position for being mounted on oil cylinder a5 piston rod terminal at this time
Set sensor aLS1, issuing signal, to obtain the repairing electromagnet DT3 of electromagnetic switch valve 3 electric, high pressure oil through solenoid directional control valve 1 the
One actuator port A flow to the oil inlet of electromagnetic switch valve 3, then passes through the oil outlet of electromagnetic switch valve 3 to the second nothing of oil cylinder b6
The piston rod continuation of rod cavity hydraulic fluid port B2, drive cylinder b6 are stretched out outward, and the oil liquid in the rod chamber of oil cylinder b6 passes through oil cylinder b6's
Second rod chamber hydraulic fluid port B2 outflow, until the second actuator port B of solenoid directional control valve 1 flows out to oil return inlet T.
When the piston rod of oil cylinder b6 it is fully extended in place after, touch oil cylinder b6 piston rod terminal position sensor bLS2 hair
Signal out makes the repairing electromagnet DT3 of electromagnetic switch valve 3 and the stretching electromagnet DT1 power loss of solenoid directional control valve 1, i.e. completion institute
It states the synchronous of two oil cylinders and stretches out operation.
2) retraction operation: the retraction electromagnet DT2 of solenoid directional control valve 1 obtains electric, and high pressure oil enters electromagnetism by oil inlet P and changes
To the second actuator port B of valve 1, high pressure oil reaches the second rod chamber hydraulic fluid port B2 of the control mouth C1 and oil cylinder b6 of balanced valve 2, drives
The piston rod of dynamic oil cylinder b6 bounces back in advance, and the rodless cavity of oil cylinder b6 is pressurized, while pressure being passed to the rod chamber of oil cylinder a5, and drive
The piston rod of dynamic oil cylinder a5 bounces back in advance.When pressure is higher than the setting pressure of 2 spring cavity of balanced valve, balanced valve 2 is reversely opened, oil
Oil liquid in the rodless cavity of cylinder a5 is discharged by the first rodless cavity hydraulic fluid port A1, by the balanced valve 1 reversely opened, using electromagnetism
First actuator port A of reversal valve 1 drains into oil return inlet T.
Since the volume production of the first rod chamber of oil cylinder a5 of the invention is slightly less than the appearance of the second rodless cavity of oil cylinder b6
Product, after the piston rod in the first rod chamber of the oil liquid drive cylinder a5 of oil cylinder b6 discharge is fully retracted to position, to eliminate this
Error is planted, the extra oil liquid in the second rodless cavity of oil cylinder b6 passes through the oil inlet of its second rodless cavity hydraulic fluid port B2 to overflow valve 4,
When oil liquid pressure is higher than the setting pressure of overflow valve 4, overflow valve 4 is opened, and oil liquid is changed by oil outlet to the electromagnetism of overflow valve 4
Oil return inlet T is flowed out to the first actuator port A of valve 1, until after the piston rod of oil cylinder b6 is fully retracted to position, solenoid directional control valve
1 contraction electromagnet DT2 power loss completes the synchronous operation of described two oil cylinders.
