In this embodiment, the working parameters are collected during the drilling operation performed by the actuator in the preset operation mode, where the working parameters may include a propulsion pressure and/or a rotation pressure. The pushing pressure or the rotating pressure of the executing mechanism is different from the preset operation mode when the executing mechanism clamps the drill rod, so that the executing mechanism can judge whether the executing mechanism has a drill rod clamping trend according to the working parameters, and then the executing mechanism is controlled to execute the drill rod clamping prevention operation according to the type of the drill rod clamping trend when the executing mechanism has the drill rod clamping trend.

As a further description of the corresponding embodiment of fig. 1, the actuator is in the idle state if the actuator is drilling against the air rather than against the tunnel wall. If the operating parameters include the propulsion pressure, idle driving detection and idle driving control can also be performed by: judging whether the propelling pressure is smaller than the idle stroke set pressure or not; judging whether the propulsion speed of the executing mechanism is greater than the idle stroke set speed; if the propulsion pressure is less than the idle stroke setting pressure and/or the propulsion speed is greater than the idle stroke setting speed, an idle stroke prevention control operation may be performed.
The flow described in the embodiment is described by the control scheme of the railway tunnel drilling device in practical application, so that the occurrence of the drill clamping working condition is effectively prevented, and the idle drilling can be prevented more timely.
The tunnel drilling device comprises a power mechanism, an actuating mechanism, a control valve and an electrical system.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a control system of a tunnel drilling device, where the control system of the tunnel drilling device includes a power mechanism, an executing mechanism, a control valve and an electrical system, the power mechanism includes an engine, a transfer case and a hydraulic pump, the executing mechanism includes a propulsion mechanism, an impact mechanism and a rotation mechanism, the control valve includes a propulsion proportional valve, an impact proportional valve and a rotation proportional valve, and the electrical system includes a propulsion oil pressure detection sensor, a propulsion speed detection sensor, a rotation oil pressure detection sensor, a rotation speed detection sensor, an impact oil pressure detection sensor, a drill rod position sensor and a central controller. The hydraulic pump station driven by the motor can replace a power system, an engine, a transfer case and a hydraulic pump.
The type of the drill rod trend and the corresponding drill rod locking prevention operation can be divided in the following modes:
the first-stage anti-blocking drill rod can prevent the karst cave from blocking drill rod. Before the drill rod is blocked, the drill bit enters the karst cave, and a signal for suddenly reducing the pushing pressure exists, so that the first type of drill rod blocking trend exists. Correspondingly, the anti-seizing operation aiming at the first kind of seizing trend is as follows: and reducing the propelling pressure and the impact pressure, and if the propelling pressure of the drill rod returns to a normal value within a certain time, recovering normal drilling.
And the second level is used for preventing the drill rod from being blocked and preventing the drill rod from being slowly blocked. The rotation pressure is higher than the second-level anti-seizing pressure and then gradually rises, at the moment, the second-type seizing trend is shown, and the signal can be used for limiting or preventing seizing caused by the increase of rotation resistance. Correspondingly, the anti-seizing operation aiming at the second kind of seizing trend is as follows: the propulsion speed is controlled to be reduced steplessly with the increase of the revolving pressure, and when the revolving pressure returns to the normal fluctuation range, normal drilling is resumed.
Three-stage anti-blocking drill rod and anti-cracking drill rod. When the rotation pressure is higher than the three-level anti-seizing pressure value, a third kind of seizing trend is shown at the moment. Correspondingly, the anti-seizing operation aiming at the third kind of seizing trend is as follows: the drill rod retreats, and when the rotary pressure is restored below the second-level anti-seizing drill rod pressure value, the drill rod is restored and pushed for a certain distance in a collar hole mode. And returning to a normal drilling state if the rotary pressure returns to normal within a certain time when the collar hole mode advances. If the rotary pressure does not return to the normal drilling state within a certain time, the drill rod is completely withdrawn, and the drilling operation is stopped.
Further, the present embodiment may also detect the idle driving state in the following two cases: in the first case, the propulsion speed is greater than the idle driving set speed; and in the second case, the propelling pressure is lower than the idle-beating set pressure. If the executing mechanism is in an idle drilling state, the collar hole mode can be used for advancing, and if the collar hole mode advances for a certain time, the pushing pressure reaches a normal value and then enters a normal drilling mode.
Referring to fig. 3, fig. 3 is a schematic diagram of a control principle of the anti-seizing device for a railway tunnel drilling machine according to an embodiment of the present application, in which a corresponding relationship between working parameters (propulsion pressure, impact pressure and propulsion speed) and rotation pressure (unit bar, bar) is shown, and a corresponding relationship between working parameters (propulsion pressure, impact pressure and propulsion speed) and drill rod position (unit m, m) in a seizing state is also shown. In fig. 3, the rotation pressure is on the abscissa, and the propulsion pressure, impact pressure, and propulsion speed are on the ordinate; after 0.4m of collar hole is drilled, the rotation pressure is increased from 50 to 60 through 5 s; if the rotation pressure reaches 140, the drilling mode is entered, and when the rotation pressure reaches 160 and 1s, the drilling mode is entered, and the drill rod is retracted; after the rotation pressure is reduced to 140, the drilling machine retreats back to 0.2m, then water is flushed for 2s, then the drilling machine drills forwards to 0.2+0.1m, and if the rotation pressure is normal in the process of advancing the collar hole mode for 30s, the drilling machine returns to the normal drilling state. The pressure 160 of the fully-entered drill clamping state is 10-20bar greater than the pressure 140 of the triggering anti-drill clamping state. Normal drilling mode pressure "60" is 10bar greater than collar mode pressure "50".
