The working hole pressure of propelling hydraulic cylinder processed, high-speed switch valve working hole working hole respectively with type pilot proportional pressure-reducing valve, is promoted
Working hole, the fuel tank of hydraulic cylinder are communicated；The working hole of type pilot solenoid directional control valve respectively with the working hole of check valve, fuel tank, turn
The working hole of pricker motor is communicated, and the working hole of check valve is communicated with hydraulic pump.
5. a kind of hydraulic gate TT＆C system as claimed in claim 1, it is characterised in that the high-speed switch valve is two
Three-way solenoid valve.
6. a kind of hydraulic gate TT＆C system as claimed in claim 1, it is characterised in that the type pilot solenoid directional control valve
For type pilot three-position four-way electromagnetic directional valve.
7. a kind of hydraulic gate TT＆C system as claimed in claim 1, it is characterised in that described electrical system includes pressure
Force snesor, flow sensor, amplifier, data gather computer card and rock drilling state identification system, pressure sensor are respectively mounted
The working hole of working hole, rock drill in hydraulic drive cylinder, the working hole of hydraulic motor, at nitrogen chamber, flow sensor difference
Working hole installed in hydraulic drive cylinder, at the working hole of rock drill, pressure sensor, the pressure of flow sensor collection, stream
Amount signal is handled accordingly through signal processor, and the pressure after processing, flow signal are passed to rock drilling by data collecting card
State identification system, rock drilling state identification system is by the rock drilling in the pressure of collection, data on flows and rock drilling state identification system
Slip condition database matching draws the rock drilling state residing for now rock drill and is fed back rock drilling parameter error, in controller pair
Under type pilot proportional pressure control valve, type pilot proportional pressure-reducing valve, the control of high-speed switch valve and type pilot solenoid directional control valve, pass through and adjust
Whole type pilot proportional pressure control valve, the setting pressure of type pilot proportional pressure-reducing valve, high-speed switch valve and type pilot solenoid directional control valve
On off state, corrects the flow of rock drill system, pressure error and reaches more preferable rock drilling effect.
