The action of lifting up and down and vibration damping；Angling cylinder 2 controls the action of current collecting equipment or so revolution；The effect of locked cylinder 3 is vehicle
During using diesel oil, locking current collecting equipment on bracket tightly avoids jolting with vehicle, collide.The system passes through automatically controlled
System jointly controls current collecting equipment lifting, rotary motion with hydraulic system.The lifting of elevating ram 1 acts：First solenoid valve
Obtained with the 3rd solenoid valve electric, hydraulic oil enters 1 lower end of elevating ram from oil inlet by the first solenoid valve and the 3rd solenoid valve, with
It lower end pressure in oil cylinder constantly to increase, piston 12 promotes current collecting equipment slowly to rise.The lowering action of elevating ram 1 is：The
One solenoid valve and second solenoid valve obtain electric, and hydraulic oil enters elevating ram from oil inlet by the first solenoid valve and second solenoid valve
1 upper end, as upper end pressure constantly increases in oil cylinder, piston 12 promotes current collecting equipment slowly to decline.The left-handed of angling cylinder 2 is moved
Make：First solenoid valve and the 5th solenoid valve obtain electric, and hydraulic oil is entered back from oil inlet by the first solenoid valve and the 5th solenoid valve
Turn 2 left end of oil cylinder, as left end pressure constantly increases in oil cylinder, piston 12 promotes current collecting equipment to turn left rotation.Angling cylinder 2
Dextrorotation acts：First solenoid valve and the 4th solenoid valve obtain electric, and hydraulic oil passes through the first solenoid valve and the 4th solenoid valve from oil inlet
Into 2 right end of angling cylinder, as right end pressure constantly increases in oil cylinder, piston 12 promotes current collecting equipment to turn right rotation.Locking
The action that oil cylinder 3 is unlocked：When current collecting equipment needs lifting, the first solenoid valve and the 6th solenoid valve obtain electric, and current collecting equipment is no longer
It is locked.The action that locked cylinder 3 is latched：When current collecting equipment drops to lower limit, the first solenoid valve and the 7th solenoid valve obtain
Electricity, current collecting equipment are locked.The vibration insulating system work of the device：When elevating ram 1 rises to maximum, spring 15 can be in work
It is compressed under the active force of plug 12 and guide rail, in vehicle operation, due to circuit or the irregularity of track, head room occurs
Variation, guide rail will change to the active force of spring 15, and in oil cylinder piston 12 be to the active force of spring 15 it is constant,
Therefore spring 15 can be compressed or stretched, these deflections just counteract the difference in height of headroom.The safeguard measure of the device：
When current collecting equipment disengages net in the process of running, hydraulic valve obtains electric, and 1 quick pressure releasing of elevating ram, current collecting equipment drops to
Safe altitude；When current collecting equipment rotates to maximum angle, hydraulic valve obtains electric, 2 quick pressure releasing of angling cylinder, current collecting equipment revolution
To trolley pole middle position.
