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 axis pin with bearing, the piston rod for the oil cylinder that links is hinged by bulb and vertical shift cylinder tube, connection
It is connected between the cylinder barrel and walking round frame of dynamic oil cylinder by welded still pipe, the piston rod of the jacking hydraulic cylinder leads to walking round frame
Bulb hinged is crossed, the cylinder barrel for 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 following table table 1：
1 hydraulic system electromagnet action table of table
After bracket receives shield body, it is necessary first to which shield body lifting is got up.Therefore start motor 2, pass through motor 2
Shaft coupling 3 drives hydraulic pump 4 to work, from the oil of pump 4 out by check valve 7, the electromagnet of three-position four-way electromagnetic directional valve 8-1
Y2 obtain it is electric, then fluid successively pass through three-position four-way electromagnetic directional valve 8-1 right position, balanced valve 9-1 and one-way throttle valve 10-1.Oil
Liquid comes out the rodless cavity using syncmotor 11 to lifting hydraulic cylinder from one-way throttle valve 10-1, so as to which shield body be lifted
Come.The effect of syncmotor 11 is to ensure that the extending action of lifting hydraulic cylinder keeps synchronous.And the fluid of rod chamber passes through successively
One-way throttle valve 10-1, balanced valve 9-1, the left position of three-position four-way electromagnetic directional valve 8-1, Air cooler 13 and return filter 16 are most
After return to fuel tank.After the completion of lifting hydraulic cylinder action, the electromagnet Y2 of three-position four-way electromagnetic directional valve 8-1 must not electricity.Three
The electromagnet Y4 of four-way electromagnetic reversing valve 8-2 obtains electric.The fluid then come out from check valve 7 passes through three-position four-way electromagnetic directional valve 8-
2 right position, the rodless cavity for then passing sequentially through balanced valve 9-2 and one-way throttle valve 10-2 to advance oil cylinder promote shield body Forward.
Currently into oil cylinder it is fully extended after, the electromagnet Y4 of solenoid directional control valve 8-2 must not electricity.During the spool of solenoid directional control valve works in
Position.Then the electromagnet Y1 of solenoid directional control valve 8-1 is allowed to obtain electric, solenoid directional control valve 8-1 works in left position, recycles elevating ram.
After recycling in place, solenoid directional control valve 8-1 must not be electric, and spool returns to middle position；The electromagnet Y3 of solenoid directional control valve 8-2 obtains electric, work
Making in left position recycles advance oil cylinder, makes the electromagnet Y3 of solenoid directional control valve 8-2 must not electricity after recycling in place.So just complete
Stroke that shield machine shield body advances.It is exactly to be repeatedly performed such stroke that shield machine shield body, which misses the stop, so that it may move shield body
To the entrance of the next stop.
The pressure of system is set up by overflow valve 6, since system pressure is high, is had very at the end of when system has just started running
Big impact 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 play the phenomenon that eliminating this impact force, and system is allowed 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 to detect the temperature of fuel tank fluid, is avoided
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 height is very suitable for applying to shield body translation.
