Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
As shown in Figure 1, hydraulic tiltedly cut host valve platform, including with rodless cavity 101 and rod chamber 102 oil cylinder 1, be connected to
Master control valve group 2 on oil cylinder 1 and the pressure oil circuit 3 and fuel tank 4 being separately connected with master control valve group 2；
Master control valve group 2 include the first inserted valve 5, by pipeline and sequentially connected second inserted valve 6 of the first inserted valve 5,
Third inserted valve 7 and the 4th inserted valve 8, are connected with the first reversal valve 9 on the first inserted valve 5, and the first reversal valve 9 is also with second
Inserted valve 6 is connected, and is connected with the second reversal valve 10 on third inserted valve 7, and the second reversal valve 10 also with the second inserted valve 6 and
Pipeline connection between third inserted valve 7；Overflow valve 11, and overflow valve 11 and the first reversal valve 9 are connected on 4th inserted valve 8
It is connected, and the pipeline between the second reversal valve 10 and overflow valve 11 and the first reversal valve 9 is connected to；Second inserted valve 6 is also connected with
There is pressure oil circuit, and the pipeline between the first reversal valve 9 and the second inserted valve 6 and pressure oil circuit is connected to；4th inserted valve 8 also with
Fuel tank 4 is connected, and the first inserted valve 5 is connected on the pipeline between the 4th inserted valve 8 and fuel tank 4.
Fuel tank 4, which is used to store oil liquid required when guaranteeing hydraulic system work, makes liquid by the connection between each inserted valve
It presses overall system architecture simple, reduces number of elements, reduce the size, and negotiability is big, the pipeline between each inserted valve is logical
The oilhole connection for crossing valve inner, reduces the leakage of oil mass, convenient for integrated.By reversal valve realize hydraulic oil communication,
Cutting and commutation, movement is accurate, and high degree of automation is stable and reliable in work.Overflow valve 11 is used as hydraulic pressure control valve,
Level pressure overflow, pressure stabilizing are played in hydraulic system, when system pressure increases, flow demand can be made to reduce by overflow valve 11.
Pipeline between the rodless cavity 101 of oil cylinder 1 and the first inserted valve 5 and the second inserted valve 6 is connected, and oil cylinder 1 has
Pipeline between rod cavity 102 and third inserted valve 7 and the 4th inserted valve 8 is connected.
In the hydraulic valve platform, pressure, electrical control are simple, can control liquid by the first reversal valve 9 and the second reversal valve 10
The shearing and backhaul of compression shear, shearing are divided into differential F.F. and high shear, and the switching between the two processes passes through pressure control
System is realized, quickly and energy saving；When carrying out differential F.F., the first reversal valve 9 is powered, 6 oil inlet of the second inserted valve, rod chamber 102
Oil return differential F.F. to rodless cavity 101 is realized by third inserted valve 7.When the pressure of the 4th inserted valve 8 reaches setting pressure
When, the second inserted valve 6 is opened, and fuel tank 4, and then 102 oil inlet of rod chamber are directly connected in the oil return of rod chamber 102, and rodless cavity 101 is logical

Two reversal valves 10 are solenoid directional control valve；Solenoid directional control valve suction is big, commutating period is short, long service life, and operates reliably, surely
It is qualitative good.
Drain tap 13 is also connected on pipeline between first reversal valve 9 and overflow valve 11.Drain tap 13 is for controlling oil
Limit oil pressure inside road, when oil pressure be more than drain tap 13 specify limit oil pressure after will allow oil from drain tap 13 flow out to prevent
Only excessively high oil pressure is destroyed caused by oil piping system.
The above are specific embodiment of the present utility model, from implementation process as can be seen that provided by the utility model
It is hydraulic tiltedly to cut host valve platform, the movement for tiltedly cutting master cylinder is realized using two-way plug-in valve, two-way plug-in valve can reduce element
Quantity simplifies system, minification；Hydraulic control uses Differential Control, and Differential Control can not change mentioning for flow system flow
The front lower speed for improving hydraulic cylinder；The conversion between differential F.F. and pressurized operation is controlled by pressure, it can without power on/off
It is fast without automatically controlled conversion speed to be directly converted into pressurized operation state from differential F.F. state, the working time is saved, effectively
Improve working efficiency.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
