The fueller includes oil absorption filter 1, return filter 16, oil filler 17 and liquid level relay 18, oil pressure
Device includes motor 2, shaft coupling 3 and variable pump 4, and the motor 2 drives variable pump 4 by shaft coupling 3.
Described oil gear one end connects fueller, and the other end of oil gear is respectively communicated with first by check valve 7
The oil revolving end connection fuel feeding dress of the fuel feeding end of hydraulic circuit and the second hydraulic circuit, the first hydraulic circuit and the second hydraulic circuit
Put.
Shield body, which installs separation type hydraulic system, also includes pressure gauge 5, overflow valve 6, Air cooler 13 and oil temperature liquid level gauge 15；Institute
State pressure gauge 5 and overflow valve 6 is located at fuel feeding end, the overflow valve 6 connects fueller；The Air cooler 13 is located at oil revolving end；
The oil temperature liquid level gauge 15 is on fueller
The translation hydraulic cylinder and jacking hydraulic cylinder connect shield body running gear respectively.
The shield body running gear includes walking round frame and platform structure, and the platform structure end is welded with bearing, institute
State that translation hydraulic cylinder is symmetrical to be distributed in shield body both sides, translation hydraulic cylinder includes vertical shift oil cylinder and linkage oil cylinder, vertical shift oil cylinder
Piston rod homalocephalus be connected by bearing pin with bearing, linkage oil cylinder piston rod be hinged by bulb with vertical shift cylinder tube, connection
Connected between the cylinder barrel and walking round frame of dynamic oil cylinder by welded still pipe, piston rod and the walking round frame of the jacking hydraulic cylinder are led to
Bulb hinged is crossed, the cylinder barrel of jacking hydraulic cylinder is coupled with jacking block by stud.
As a kind of embodiment of optimization, the first valve integrated package and the second valve integrated package are integrated in same valve
On door integrated package.
In concrete operations, with reference to table 1 below：
The electromagnet action table of table 1
After bracket receives shield body, it is necessary first to which shield body lifting is got up.Therefore start motor 2, motor 2 is passed through connection
Axle device 3 drives hydraulic pump 4 to work, and the oil come out from pump 4 passes through check valve 7, and three-position four-way electromagnetic directional valve 8-1 Y2 obtains electric,
Then fluid sequentially passes through three-position four-way electromagnetic directional valve 8-1 left position, balanced valve 9-1 and one-way throttle valve 10-1.Fluid is from list
The rodless cavity of lifting hydraulic cylinder is out arrived by syncmotor 11 again to choke valve 10-1, so that shield body lifting be got up.It is synchronous
The effect of motor 11 is that the extending action for ensureing lifting hydraulic cylinder keeps synchronous.And the fluid of rod chamber sequentially passes through one-way throttle
Valve 10-1, balanced valve 9-1, three-position four-way electromagnetic directional valve 8-1 right position, Air cooler 13 and return filter 16 eventually pass back to oil
Case.After the completion of lifting hydraulic cylinder action, three-position four-way electromagnetic directional valve 8-1 Y2 must not electricity.Three-position four-way electromagnetic directional valve
8-2 Y4 obtains electric.The fluid then come out from check valve 7 passes through three-position four-way electromagnetic directional valve 8-2 right position, then passes sequentially through
The rodless cavity of balanced valve 9-2 and one-way throttle valve 10-2 to advance oil cylinder promotes shield body reach.Currently enter oil cylinder it is fully extended after,
Solenoid directional control valve 8-2 Y4 must not electricity.The valve element of solenoid directional control valve works in middle position.Then solenoid directional control valve 8-1 Y1 is allowed to obtain
Electricity, solenoid directional control valve 8-1 works in left position, reclaims elevating ram.After reclaiming in place, solenoid directional control valve 8-1 must not be electric,
Valve element returns to middle position；Solenoid directional control valve 8-2 Y3 obtains electric, and working in left position reclaims advance oil cylinder, makes electricity after reclaiming in place
Magnetic reversal valve 8-2 Y3 must not electricity.So just complete a stroke of shield machine shield body advance.Shield machine shield body, which misses the stop, is exactly
It is repeatedly performed such stroke, so that it may which shield body is moved on to the entrance of the next stop.
The pressure of system is set up by overflow valve 6, because system pressure is high, is had very with the end of when system has just started running
Big impulsive force, this can cause cylinder jiggly phenomenon occur when promoting shield body translation or jacking shield body, so may
Cause the damage of shield body inclination, fluid pipeline and component.Overflow valve 6 and two-position two-way electromagnetic directional valve 14 are used cooperatively again can
With to system release.Balanced valve 9-1 and 9-2 just serve the phenomenon for eliminating this impulsive force, allow system to remain steady shape
State is run.Air cooler 13 plays the cooling effect of fluid；The effect of oil temperature liquid level gauge 15 is the temperature for detecting fuel tank fluid, it is to avoid
High oil temperature and system also continues to work；The effect of oil filler 17 is to fuel tank repairing；Liquid level relay 18 is to detect oil
The minimum liquid level of case, when fluid is less than minimum liquid level, then liquid level relay 18 will send alarm signal, and stop system
Only work.
This set hydraulic system operation is easy, safe and reliable, synchronism is high is especially suitable for applying to shield body translation.
