The installation site and mode of above-mentioned only all parts, in order to illustrate the principle of the present apparatus, it is necessary to will in conjunction with Fig. 3
The connection of each device is described in detail below.
As shown in figure 3, spiral rotating oil cylinder quick closedown high-pressure gas-liquid linkage includes:
With spiral rotating oil cylinder 9 by the piston accumulator 2 of piping connection and fuel tank 7, be mounted on spiral rotating oil cylinder 9
Shutoff valve C 26 and logical valve A28 on oil inlet lateral line, the shut-off valve being mounted on 9 oil extraction lateral line of spiral rotating oil cylinder
D27, logical valve B31 successively install gas-liquid booster pump 14, high-pressure filteration on the pipeline between the fuel tank 7 and logical valve A28
Device 17, shut-off valve A18 and check valve 19, and the pipeline between fuel tank 7 and logical valve A28 is connected to piston accumulator 2.
Shut-off valve B20 is installed on the pipeline of 19 back segment of check valve.
Gas-liquid booster pump 14 is sequentially connected with pneumatic triple piece solenoid valve 16 and quick connector ball valve 10, above-mentioned for driving
Valve arrangement.
Oil pressure gauge 3 can be installed on the pipeline between high pressure filter 17, shut-off valve A18.
Be installed in series on pipeline between 9 oil inlet side of spiral rotating oil cylinder and oil extraction side two-position three way magnetic valve A22 and
Two-position three way magnetic valve B23, and pressure is installed on the pipeline between two-position three way magnetic valve A22 and two-position three way magnetic valve B23
Power switch A5 and overflow valve 21.
Pacify respectively on pipeline between two-position three way magnetic valve A22 and two-position three way magnetic valve B23 and spiral rotating oil cylinder 9
Fill hydraulic control one-way valve A24 and hydraulic control one-way valve B25.
The gas side installation shut-off valve E29 and charge valve 30 of piston accumulator 2, can install nitrogen pressure on loading line
Power table 4, pressure switch C13 and gas safety valve 12.
The effect of above-mentioned logical valve A28 and logical valve B31 are the discharges of control oil, by connecting two-position two-way solenoid valve
A32 and two-position two-way solenoid valve B33 are controlled, and two two-position two-way solenoid valve series connection are needed two-position two-way solenoid valve A32
It is powered simultaneously with two-position two-way solenoid valve B33, the control oil of logical valve A28 and logical valve B31, such Redundancy Design could be discharged
The risk of maloperation can be reduced.Pressure switch B6 can be installed on series pipe.
The nitrogen of specified amount is filled in the gas side of piston accumulator 2, then by gas-liquid booster pump 14 to piston accumulator 2
Oily side carry out oil-filled pressure accumulation, the gas spring never to fail is served as using compressed high pressure nitrogen, the energy as quick closing valve movement
Amount source.Compared to traditional mechanical spring, gas spring is light-weight, and time ground uses will not largely can fail.
Energy is stored using the high pressure nitrogen in piston accumulator 2, when carrying out quick closing valve movement, high pressure nitrogen is quickly swollen
It is swollen, push high pressure oil after logical valve 28, shut-off valve 26 by the piston in piston accumulator 2, into spiral rotating oil
The side of cylinder 9, the hydraulic oil of 9 other side of spiral rotating oil cylinder are discharged into fuel tank 7 after shut-off valve 27, logical valve B31.Spiral
The pressure maximum of 9 oil inlet side of rotary oil cylinder can reach the pressure of accumulator mesohigh nitrogen, when compressed nitrogen pressure is enough
High (25MPa at present), then the appropriate active area for increasing by 9 oil inlet side of spiral rotating oil cylinder, spiral rotating oil cylinder 9 be it is exportable very
Big torque (up to 100,000 NM).
As shown in Figure 3, Figure 4, since there are logical valve A28 and logical valve in the oil inlet side of spiral rotating oil cylinder 9 and oil extraction side
B31, when acting without quick closing valve, the high pressure oil stored in accumulator 2 is closed logical valve 28 and 31 by control piper, from
And make system slowly open and slowly pass channel be isolated with accumulator 2.In this way, be not necessarily to before having carried out a quick closing valve movement
Pressure accumulation repeatedly is carried out to accumulator 2, meanwhile, actuator do start slowly make when, it is thus only necessary to overcome the load of valve, without gram
Take the nitrogen pressure in accumulator 2.Moreover, when valve is in the open position, in the spiral rotating oil cylinder 9 of actuator only very
Low pressure (0~2MPa or so), high pressure, which is locked in, to be existed only in accumulator 2 and its relevant pipeline, to reduce
The risk of leakage of system.
After accumulator completes oil-filled pressure accumulation, only two-position two-way solenoid valve A32 is powered, high pressure oil can make pressure switch 6
Alarm, and quick closing valve does not occur for actuator, thus illustrate that two-position two-way solenoid valve A32 can be operating normally, two-position two-way solenoid valve B33
It closes in place, then powers off two-position two-way solenoid valve A32, two-position two-way solenoid valve B33 is powered, and pressure switch B6 resets, and says
Bright two-position two-way solenoid valve B33 can be operating normally.It thus can be in the case where actuator be acted without quick closing valve, to two
The solenoid valve of the two decision quick closing valve functions of two-way electromagnetic valve A32 and two-position two-way solenoid valve B33 carries out on-line checking.
High pressure filter 17, shut-off valve A18, check valve 19, shut-off valve B20, overflow valve 21, two-position three way magnetic valve A22,
Two-position three way magnetic valve B23, hydraulic control one-way valve A24, hydraulic control one-way valve B25, shutoff valve C 26, shut-off valve D27, logical valve A28,
Logical valve B31, two-position two-way solenoid valve A32, two-position two-way solenoid valve 33 are integrated into change down slowly and close in quick closing valve valve block 8, cut-off
Valve E29, charge valve 30 are integrated into air pressure valve block 15.
Specific control logic is controlled as Fig. 4 gives valve.
Spiral rotating oil cylinder 9 as shown in Figure 5 is made of cylinder barrel 41, end cap 34, piston 36, transmission shaft 35.Transmission shaft 35
End is machined with boss, and adapter 4 is installed in 35 end of transmission shaft, and in the side of above-mentioned boss, the outside installation of transmission shaft 35 is led
To set 39, guide sleeve 39 is positioned by boss, while installing stroke limit block 38 in the other side of boss, is fixed on cylinder barrel 41
It is interior, 36 outside screw of piston installation tooth set 37, stroke its as tooth set 37 with piston 36 move buffer units, reduce quickly
The impact force of closing.
Output end of the spiral rotating oil cylinder 9 as the device, operating pressure are 25MPa~30MPa, eliminate shift fork case
Body.The arrangement of hydraulic and pneumatic line than mechanical transmission structure flexible arrangement much so that components layout is more clever
