Piston rod 39, the flow distributors such as the fourth stage piston rod 4 11 be attached separately to corresponding cylinder barrel 28, cylinder barrel 3 10, cylinder barrel
In 4 12；The outer end of the flow distributors such as the first order is equipped with plug 1, and the end of the flow distributors such as afterbody fills
There is reversed recharging oil device, is equipped with reset spring 13, the outer end of spring spool 14 in the spring spool 14 of the reversed recharging oil device
Portion is equipped with plug 2 15；The at different levels cylinder barrels that wait flow distributors of the equal flow distributors in addition to the first order all have vent valve 6, with
Air pressure and atmospheric pressure when making up the movement of each piston rod between each cavity balance；In the cylinder barrel 1 of the equal flow distributors first order
The both ends of chamber are respectively equipped with oil inlet 2, oil outlet 5, and oil inlet 2, oil outlet 5 are respectively placed in the two sides of piston rod 1, other each
Cylinder barrel one end of the flow distributors such as grade is equipped with oil outlet 5；A repairing mouth 16 is added in the middle part of equal flow distributors, using storage
Energy 23 repairing of device, repairing mouth 16 are communicated with the check valve 17 of equal flow distributors at different levels.
The hydraulic control system of the equal flow distributors includes manual pump 18, manual pump overflow valve 19, manual pump off-load
Valve 20, etc. flow distributors, overflow valve 21, rotary valve 22, accumulator 23, pressure gauge 24 and shut-off valve 25, hydraulic cylinder 1, hydraulic
Cylinder 2 27, hydraulic cylinder 3 28, hydraulic cylinder 4 29, valve block 35, rotary valve 22 and 21 integrated installation of overflow valve wait flows in valve block 35
The cylinder barrel oil outlets 5 at different levels of distributor are respectively by the correspondence oil inlet 1 in valve block 35, with oil outlet 1, oil outlet two
32, oil outlet 3 33, oil outlet 4 34 are connected to.Manual pump 18 is suppressed, 18 fuel feeding of manual pump gives accumulator to repairing mouth 16
23 fuel feeding close shut-off valve 25, continue to suppress manual pump when the pressure gauge 24 connecting with accumulator 23 reaches setup pressure value
18, then hydraulic control system moves the piston rod 1 for waiting flow distributors to 2 fuel feeding of oil inlet of equal flow distributors, from
And piston rod 1 pushes remaining piston rod 27, piston rod 39, piston rod 4 11 synchronization action together.When rotary valve 22 is all located
In opening state, then the hydraulic oil come out from the cylinder barrel oil outlets 5 at different levels of equal flow distributors passes through pair in valve block 35 respectively
Oil inlet 1 is answered, through oil outlet 1, oil outlet 2 32, oil outlet 3 33, oil outlet 4 34, is controlled by corresponding rotary valve 22,
Enter back into hydraulic cylinder 1, hydraulic cylinder 2 27, hydraulic cylinder 3 28, hydraulic cylinder 4 29, make hydraulic cylinder 1, hydraulic cylinder 2 27,
Hydraulic cylinder 3 28, hydraulic cylinder 4 29 act.When needing makes certain hydraulic cylinder be failure to actuate, the rotary valve 22 in valve block 35 is operated, makes to supply
Fuel tank is returned to by overflow valve 21 to the oil of this hydraulic cylinder, remaining hydraulic cylinder normal fuel injection, regular event.When this hydraulic cylinder of needs
When continuing movement, then rotary valve 22 is opened, then continues to realize hydraulic cylinder synchronous sex work to this hydraulic oil supply cylinder.Such as Fig. 3 institute
Show, when rotary valve 22 is all opened, hydraulic cylinder 1, hydraulic cylinder 2 27, hydraulic cylinder 3 28, hydraulic cylinder 4 29 are worked at the same time；Work as a left side
When side rotary valve 22 is closed, left side hydraulic cylinder 1,2 27 fuel cut-off of hydraulic cylinder are not reoperated；When the right rotary valve 22 is closed,
The right hydraulic cylinder 3 28,4 29 fuel cut-off of hydraulic cylinder, do not reoperate.Manual pump 18 is operated at this time, and oil directly passes through overflow valve
21 return to fuel tank.The utility model can realize the movements such as stretching, the retraction of each equal flow distributors piston rod, or combine
It uses, so that a few groups of piston rods stretched out, retracted jointly, to meet the needs of different operating conditions.Consider operation convenience, this hydraulic control
System processed is operated using bilateral, including two manual pumps 18 and two valve blocks 35, and there are two rotary valves 22, two for band in each valve block 35
21, four oil inlets 1 of a overflow valve and oil outlet 1, oil outlet 2 32, oil outlet 3 33, oil outlet 4 34.In equipment
Two sides can individually control the run action of each hydraulic cylinder.
The utility model pushes away more structures using one, waits flow distributors fuel feeding by one, while being pushed by mechanical part
Remaining equal flow distributor moves together, and the running stroke for reaching all equal flow distributors is consistent, the assignment of traffic such as makes
The hydraulic oil that device supplies each oil cylinder is same volume, guarantees that the running stroke of each oil cylinder is consistent.
Each internal diameter of cylinder size of the utility model is consistent, it is ensured that the oil mass volume one come out from each cylinder barrel
It causes, keeps each piston rod stroke consistent, guarantee each synchronism for waiting flow distributors.When each equal flow distributors pressure release, by multiple
Position spring 13 heads on 4 11 return of piston rod, and the oil in oil cylinder is returned in respective cylinder barrel at this time.In order to solve each cylinder barrel and oil
The problems such as letting out in oil between cylinder increases a repairing mouth 16 at the middle part of equal flow distributors, using 23 repairing of accumulator.
