It not rock drill rock drilling fltting speed, rock drill oil-in flow, rock drill oil return opening flow.
Rock drill when normal rock drilling duty, by pressure transducer P1, P2, P3, P4 and flow transducer Q1,
In Q2, Q3 monitor pressure, flow parameter and rock drilling state identification system S obtained in real time, the contrast of rock drilling slip condition database can
Obtain the rock drilling state residing for rock drill Z3 and rock drilling work parameter error:
When flow transducer Q1, Q2 monitor at the working hole Z1-A of hydraulic drive cylinder Z1, the working hole Z3-A of rock drill Z3
Normal flow that flow parameter sum is corresponding less than rock drilling slip condition database in now rock drilling state identification system S and time, rock drilling
State identification system S controls the rotating speed of converter T raising motor M1 by controller R thus increases in the hydraulic pump B1 unit interval
Discharge capacity so that the flow parameter sum that flow transducer Q1, Q2 monitor reaches normal flow.When flow transducer Q1,
The flow parameter sum that Q2 real-time monitors at the working hole Z1-A of hydraulic drive cylinder Z1, the working hole Z3-A of rock drill Z3 is higher than
Now corresponding in rock drilling slip condition database in rock drilling state identification system S normal flow and time, rock drilling state identification system S is led to
Cross the rotating speed of controller R control converter T reduction motor M1 thus reduce the discharge capacity in the hydraulic pump B1 unit interval, so that stream
The flow parameter that quantity sensor Q1, Q2 monitor reaches normal flow.When flow transducer Q1, Q2 are respectively at hydraulic drive cylinder Z1
The flow parameter sum that real-time monitors of working hole Z1-A, the working hole Z3-A of rock drill Z3 and rock drilling state identification system S
Normal flow sum contrast corresponding in interior rock drilling slip condition database, show that flow now is corresponding with in rock drilling slip condition database

The pressure parameter real-time monitored at hydraulic drive cylinder Z1 working hole Z1-A as pressure transducer P1 is less than now digging
During the normal pressure that in rock state identification system S, rock drilling slip condition database is corresponding, guide proportion is subtracted by rock drilling state identification system S
Pressure valve Y2 carries out pilot control, properly increases the setting pressure of guide proportion air relief valve Y2, so that pressure transducer P1 monitoring
To flow parameter reach normal pressure；When the pressure that pressure transducer P1 real-time monitors at hydraulic drive cylinder Z1 working hole Z1-A
When force parameter is higher than corresponding in rock drilling slip condition database in now rock drilling state identification system S normal pressure, rock drilling state is distinguished
Knowledge system S carries out pilot control by controller R to guide proportion air relief valve Y2, suitably reduces setting of guide proportion air relief valve Y2
Constant-pressure, so that the pressure parameter that pressure transducer P1 monitors reaches normal pressure.When pressure transducer P1 is at hydraulic thrust
Enter pressure parameter that cylinder Z1 working hole Z1-A the real-time monitors normal pressure corresponding with rock drilling slip condition database consistent time, control
Device R does not carries out any action to guide proportion air relief valve Y2.
The pressure parameter carrying out real-time monitoring at the working hole Z3-A of rock drill Z3 as pressure transducer P2 is less than now
During corresponding in rock drilling state identification system S rock drilling slip condition database normal pressure, properly increase guide proportion overflow valve Y1's
Set pressure, so that the pressure parameter that pressure transducer P2 monitors reaches normal pressure；When pressure transducer P2 is in rock drilling
The pressure parameter that the working hole Z3-A of machine Z3 carries out real-time monitoring is higher than standard pressure corresponding in now rock drilling slip condition database
During power, suitably reduce the setting pressure of guide proportion overflow valve Y1, so that the pressure parameter that pressure transducer P1 monitors reaches
To normal pressure；When pressure transducer P2 carries out the pressure parameter and the rock drilling that real-time monitor at the working hole Z3-A of rock drill Z3
When normal pressure corresponding in slip condition database is consistent, controller R does not carries out any action to guide proportion overflow valve Y1.
When differential pressure pickup P3 is turning pressure reduction parameter that pricker motor Z4 working hole Z4-A, Z4-B real-time monitor less than now
During corresponding in rock drilling slip condition database standard pressure reduction, there are two kinds of situations: if flow transducer Q1 is in the work of hydraulic drive cylinder Z1
Make the mark that flow parameter that mouth Z1-A real-time monitors is corresponding with in rock drilling slip condition database in now rock drilling state identification system S
When quasi-flow is compared too low, it is big that rock drilling state identification system S improves high-speed switch valve G1, G2 power on/off electric current by controller R
Little and conduction time dutycycle, the flow parameter making flow transducer Q1 monitor reaches normal flow；If flow transducer Q1
The flow parameter real-time monitored at the working hole Z1-A of hydraulic drive cylinder Z1 and rock drilling status number in rock drilling state identification system S
According to when in storehouse, the normal flow of correspondence is consistent, controller R does not carries out any action to high-speed switch valve G1, G2.Work as pressure difference sensing
