See also Figure 14 to Figure 18, there is shown the fundamental diagram that hydraulic pressure is crossed the iron protection system, wherein, the synchronism of its motion is controlled in two main hydraulic cylinder 33 parallel connections jointly by flow divider-combiner 32 and mechanical guide.
During the left side position cut-in operation of main reversing valve 27, piston moves ahead, be hampered stop after, pump continues to accumulator 28 topping ups, pressure increases, and until reaching setting pressure, makes the forward thrust of double hydraulic cylinder reach predetermined 2.68 * 10
6N, this moment, control system made whole electromagnet dead electricity according to the pressure signal of pressure sensor 21, electromagnetic relief valve off-load (can consider to close pump, look the decision of pump start and stop frequency in the debugging).If after a period of time work, accumulation of energy deficiency in the accumulator, pressure reduces, and according to the pressure signal of pressure sensor 30 position, main reversing valve 27 left side is inserted, and pumping source is again to the accumulator topping up.
In shattering process, increase the trend of retreating that produces as main hydraulic cylinder because of crushing force, because of hydraulic control one-way valve 29 shutoff oil circuit, hydraulic cylinder rodless cavity pressure is raise, after reaching the set pressure of overflow valve 31, can allow main hydraulic cylinder to retreat by this valve overflow, the resistance that retreat this moment (can reach 3.54 * 10 by the pressure regulation decision of overflow valve 31
6N).This pressure signal transfers to control system by pressure sensor 30, and control system is carried out " crossing iron " action.
During 27 right cut-in operations of main reversing valve, charge oil pressure is opened hydraulic control one-way valve, and the oil-feed of main hydraulic cylinder rod chamber retreats, by choke valve 26 its suitable astern speeds of control.If this moment, main hydraulic cylinder 33 was subjected to the very big external force that retreats, then choke valve 26 can stop it to retreat fast, and it is bigger when retreating external force, when hydraulic cylinder rodless cavity pressure reaches overflow valve 31 set pressures, then main hydraulic cylinder still can be because of overflow valve 31 overflows retreat fast, and this just can guarantee that system avoids damaging.
Pumping source 14～16 is provided with two covers, works alone respectively.One cover work, another set of standby.
Hydraulic pressure is crossed action of iron protection system and control mode thereof:
In course of normal operation, make main reversing valve left side position insert (IDT "+") earlier, master cylinder 33 right laterals, walk to stroke terminal after, accumulator is pressurized to setting pressure, the pressure signal of pressure sensor 30 determines that crusher main engine can start working.
Do in the process crossing the ironworker, if master cylinder makes a concession because of crushing force is excessive, then pressure sensor 30 high pressure occurs (＞18.5MPa) signal illustrate that non-broken thing exists, and control system will be carried out " iron " and move.Its process is: close charging aperture; and make hydraulic pressure cross iron protection system main reversing valve 27 to switch to the work of right position; master cylinder 33 is retreated; when the protruded stigma (attached explanation in addition) in master cylinder piston left side enters left cylinder cap counterbore; high pressure appears in pressure sensor 34, and (＞19MPa) signal has illustrated " retreating to discharge gate 250mm ", makes master cylinder recover to move ahead and timing then immediately; after reaching setting pressure to pressure sensor 30, charging aperture recovers charging.
In removing the non-broken thing of super large, in " cross iron " back master cylinder moves ahead 30 seconds (debugging is determined) of action, if pressure sensor 30 go out again high-voltage signal (＞18.5MPa), illustrate that master cylinder moves ahead to be hampered, non-broken thing is not discharged, and then control system makes main frame shut down immediately and brakes.Main frame stops back (determining the Main Engine Cut-Off braking time by debugging); hydraulic pressure is crossed the iron protection system and is transferred manual control to, and inching button control main hydraulic cylinder retreats, and position, solenoid directional control valve 26 left side is inserted; main hydraulic cylinder is retreated to stroke terminal, then by the non-broken thing of artificial removing super large.Whole system can be recovered " operate as normal " after finishing.
When quitting work (or anxious stopping) at needs, the main frame stall is closed, made to the control charging aperture earlier, and the electromagnet that hydraulic pressure is crossed iron protection system reversal valve all is in " dead electricity " state, and transfers manual control to.
In the course of the work,, can make the motor of control system closing fault pump, start the stand-by pump motor, resume work immediately by pressure signal if pumping source breaks down.
When adjusting jaw discharging opening size; elder generation's crawl control retreats to stroke terminal (position, solenoid directional control valve 27 left side is inserted) master cylinder 33; after unclamping piston rod and adjusting the mechanical connection (tool structure chart according to circumstances) of pad; control reversal valve 22 right positions and position, 19 left side are inserted; make two auxiliary cylinders 21 stretch out jack-up jaw (need determine before this that master cylinder 33 located to step back the position); reversal valve 19 is cut to meta pinning auxiliary cylinders 21; whole electromagnet dead electricity; hydraulic pressure is crossed the iron protection system and is in unloading condition, can change the pad operation then.After operation is finished, must earlier reversal valve 19 be switched to right position, control auxiliary cylinders 21 is retracted to stroke terminal, and the switchback meta after mechanical connection is finished, can switch to solenoid directional control valve 22 position, a left side again, and main system is resumed work.
About hydraulic pressure is crossed iron protection system operating instruction: by reversal valve 19 and 22 auxiliary hydraulic cylinders that connect 20, be used when adjusting the discharging opening size, back down moving jaw when auxiliary cylinders is stretched out, so that change pad.
The adjustment of closed edge discharge gate is arranged: closing the limit discharge gate is 100 ± 30mm, by adjusting increasing, subtracting and adjust of pad.
Stop at main frame, under the state that main hydraulic cylinder 33 is return, unload lower piston rod and the mechanical connection of adjusting pad earlier, (4DT "-") inserted in reversal valve 22 right positions then, but (5DT "+") inserted in position, crawl control this moment reversal valve 19 left side, makes two auxiliary cylinders 21 stretch out jack-up bracket and moving jaw, after discharging inching button, reversal valve 19 is in meta, and auxiliary cylinders 21 is pinned, and can manually adjust pad.
After adjustment is finished, (6DT "+") inserted in crawl control reversal valve 19 right positions, auxiliary cylinders 21 is return, after discharging inching button, reversal valve 19 still returns meta, pins auxiliary cylinders 33, after finishing piston rod and adjusting the mechanical connection of pad, again (4DT "+") inserted in position, reversal valve 22 left side, this moment, two auxiliary cylinders were in " returning unsteady, the locking of advancing " state.
