[specific embodiment]
Below in conjunction with accompanying drawing enforcement of the present utility model is described below:
In Fig. 1, inflating pump 1 is connected with the air dryer 2 of band unloader and four-loop protection valve, and air dryer 2 is connected with main gas tank 4, secondary gas tank 3, and the outlet side of main gas tank 4 and secondary gas tank 3 is connected hanging oil cylinder locking electromagnetic valve 5 and gear locking electromagnetic valve 8; The outlet side of hanging oil cylinder locking electromagnetic valve 5 is connected with Pneumatic hydraulic valve 7, is provided with the A mouth 6 of centre revolving joint between hanging oil cylinder locking electromagnetic valve 5 and the Pneumatic hydraulic valve 7, and the leading-out terminal of hanging oil cylinder locking electromagnetic valve 5 is connected with switch 16; The outlet side of gear locking electromagnetic valve 8 is connected with cylinder 9, and the leading-out terminal of gear locking electromagnetic valve 8 is connected with switch 16; Also connect the parking braking valve 11 gentle electromagnetic valves 10 of stopping on the main gas tank 4; The stop outlet side of electromagnetic valve 10 of gas is connected with quick release valve 14, and the stop leading-out terminal of electromagnetic valve 10 of gas is connected with switch 16; Gas is stopped and is provided with the B mouth 15 of centre revolving joint between electromagnetic valve 10 and the quick release valve 14; Brake chamber 12 and spring braking air chamber 13 before the outlet side of parking braking valve 11 and quick release valve 14 is connected.
During work, inflating pump 1 provides work source of the gas dry, safety through air dryer 2, and source of the gas is sent into secondary gas tank 3, main gas tank 4.
Starting switch 16, hanging oil cylinder locking electromagnetic valve 5, behind the R mouth of hanging oil cylinder locking electromagnetic valve 5, A mouth 6 that the A mouth enters centre revolving joint, enter Pneumatic hydraulic valve 7, its inner cylinders promotes the action of hydraulic valve spool, thereby the oil circuit of locked hanging oil cylinder, car load hangs and becomes hard connection, has improved the work capacity of excavator greatly.
Simultaneously, gear locking electromagnetic valve 8 gets electric, cylinder 9 air inlets, and cylinder rod stretches out, inserts in the hole of gearbox gear pull bar, the gearbox neutral, gearbox files when preventing excavator work, causes gearbox and clutch abrasion.
Simultaneously, gas stop electromagnetic valve 10 electric air inlet, the braking of front and back wheel is finished in brake chamber 12 and spring braking chamber 13 gas source enters respectively after the B of centre revolving joint mouth 15 enters quick release valve 14 before, thus the stability when guaranteeing that excavator is worked.
When pressing the corresponding function switch of switch 16 separately, can lock a kind of action wherein separately.
