Operating procedure of the present invention:
1, start preparation: connect three phase mains, close isolation reversing switch 88, and electric control box 86 control transformer 90 works, and control line rood electricity, power supply indicator is bright, complete machine place holding state.
2, complete machine starts: press power knob switch 95 the green button, contactor 92 adhesive, and main circuit is connected, actuating motor 38.Motor 38 operates and drives oil pump 61 pump oil, through priority allocation valve 69 to hydraulic steering gear 62 and (or) running motor 43 and (or) multi-way control valve 64, handle the corresponding control stick of multi-way control valve 64, drive executive component running motor 43, oil buffer 70, each operating cylinder, drum motor 68 to work, oil return flows back to fuel tank 82 through return filter 76, radiator 77.
3, walk and turn to: promoting multi-way control valve 64 forward or backward and to walk the control crank of valve block, walking valve block just (or) oppositely connect, hydraulic oil drive running motor 43 just (or) reversion, by machine driven systems such as gearboxes, drive forward and backward bridge vehicle wheel rotation, realize complete machine traveling forward and back; During walking valve block control crank place's interposition, walking valve block place cut-off state, vehicle stops.Steering dish, hydraulic oil preferentially enters hydraulic steering gear 62 through priority allocation valve 69, drives steering cylinder 63 action, controls Vehicular turn.
4, lifting and shoveling: the control crank promoting multi-way control valve 64 conveying mechanism descending valve plate forward or backward, conveying mechanism descending valve plate just (or) oppositely connect, hydraulic oil drives hoist cylinder 26 action, realizes conveying mechanism lifting.When hoist cylinder 26 stretches out, conveying mechanism rear portion is raised, and shovel mouth falls, and is convenient to shoveling and entrucking; Hoist cylinder 26 all stretches out, and conveying mechanism rear portion is lifted to the highest, and shovel mouth lands, and wheelie lifts simultaneously; When hoist cylinder 26 is retracted, conveying mechanism rear portion falls, and shovel mouth is raised and is convenient to vehicle to run.
5, entrucking is carried: the control stick promoting multi-way control valve 64 correspondence conveying motor control valve block forward or backward, drum motor 68 operates, hydraulic drum 28 is driven to drive the work of conveying shedding mechanism, drum motor 68 controls valve block and divides forward, oppositely connection and cut-off three working positions, and respective rollers motor 68 rotates forward, reverses and stops.If what adopt is electric drum, then controlled with three press buttones.
6, excavate material loading: the control stick handling the corresponding control valve block such as big arm cylinder 15, oil cylinder of small arm 14, bucket cylinder 11, angling cylinder 17 of multi-way control valve 64 respectively, then handle big arm cylinder 15, oil cylinder of small arm 14, bucket cylinder 11, angling cylinder 17 action respectively.Hormany operating large arm 13, forearm 12, bucket 6 action, control bucket 6 running orbit, thus complete revolution and excavate feeding process.Handle angling cylinder 17 action, promote revolving body 16 and rotate, drive digging mechanism revolution.
7, impact grinding: handle the clamping oil cylinder 67 that rotary valve 74 connects bucket, hammer fast replacing device 8, handle sheet (namely bucket cylinder the controls valve block) action of multi-way control valve 64 correspondence clamping ram control valve, application piston bar is retracted, and clamping hook unclamps, and gets loose and puts down bucket 6; Change the outfit after quartering hammer, handle clamping oil cylinder 67 piston rod and stretch out clamping hydraulic quartering hammer 7.Connect the hydraulic hose snap joint of hydraulic breaking hammer 7, connect impact oil cylinder 65 and top compressing cylinder 66 hydraulic circuit of hydraulic breaking hammer 7.Handle the corresponding big arm cylinder of multi-way control valve, oil cylinder of small arm control valve block respectively, adjustment hydraulic breaking hammer 7 hammers operating attitude into shape, the corresponding hydraulic breaking hammer 7 of manipulation multi-way control valve 64 impacts oil cylinder 65, top compressing cylinder 66 controls valve block, starts hydraulic breaking hammer 7 and implements high-frequency percussion fragmentation, clears up operation of getting rid of the danger.
8, vehicle speed variation: transfer case 44 has high and low, empty three gears, handles engage a gear bar, conversion gearbox-gear and car speed.Front gear is low or first gear, and middle gear is neutral gear, and rear gear is top gear.High gear is used for empty wagons walking, and low-grade for drive hoeing machine work, neutral gear is used for trailer traction.
9, service brake: step on brake pedal 51, master cylinder 52 valve rod compresses, and to brake fluid pressurization, drives hub for vehicle wheel inside brake cylinder working, forces braking horseshoe to compress wheel hub and realizes service brake.
10, shut down: press the red stop button of power knob switch 95 or suddenly stop knob 96, control circuit dead electricity, power supply indicator goes out, complete machine place stopped status, but the transformer 90 of electric control box 86 still has electricity.Disjunction isolation reversing switch 88, pulls up three-phase power socket, cutting electromechanical source.
11, without electricity operation: during without mains supply, startup diesel engine 37, works in conjunction with clutch or shaft coupling 47 drive motor 38 and oil pump 61.
