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 main hydraulic 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.
The operation principle of spring adjusting device 300 of the present invention is: adopt hydraulic pressure to cross the method for the adjustment magnetic valve interlock of the reversal valve 27 of iron protection system and spring adjusting device; when disintegrating machine normally moves; close the limit discharge gate and be set in the scope of 100 ± 30mm; hydraulic pressure is crossed the reversal valve energising work of iron protection system, adjusts magnetic valve 307 and is in power failure state.When above-mentioned pressure sensor 30 occur high pressure (＞18.5MPa) during the non-broken thing of " cross iron " of signal and removing super large; hydraulic pressure is crossed iron protection system main reversing valve 27 and is switched to the work of right position; when main hydraulic cylinder 33 retreats; adjusting magnetic valve 307 gets; hydraulic pressure cylinder assembly 305 work; promoting piston 352 advances forward and moves becoming flexible of the bracket 101 that causes the lax naturally of spring 303 and cause because of the rotation of moving jaw 5 backward at moving jaw 50 pull bar 301 when eccentric shaft 60 rotates with compensation; thereby spring 303 can and be removed in the non-broken thing process of super large " crossing iron ", remain impaction state.On the contrary, after " cross iron " and the non-broken thing of removing super large are finished, whole system can be recovered " operate as normal ", when master cylinder recovers to move ahead, 352 in the piston of hydraulic pressure cylinder assembly 305 makes to remain impaction state at piston 352 back off procedure medi-springs 303 to retreat with the main hydraulic cylinder same speed of advancing forward thereupon.This hydraulic pressure cylinder assembly 305 and main hydraulic cylinder 33 synchronously and the opposite operation of direction, to avoid crossing iron " and when removing the non-broken thing of super large spring the vibration that causes of relaxing suddenly, to the bump of attaching parts and the damage that may cause.
It should be noted, pressure in the work of the piston 352 of hydraulic pressure cylinder assembly 305 preferably keeps close or consistent with the operating pressure of main hydraulic cylinder 33 so that spring 303 keeps very steady on discharge gate is regulated, so this operating pressure is selected 8 to 10 tons basically.
