Embodiment Construction
[0011] The on-line control hydraulic drilling anti-seize method described in the embodiment of the present invention, its main steps include:
[0012] ⑴First, arrange the anti-jamming circuit, which consists of impactor, propulsion motor and rotary motor. The oil circuit of the impactor is connected to a propulsion pump, and the external connection of the propulsion motor and rotary motor is connected to the online monitoring device;
[0013] ⑵This online monitoring device is connected with a remote computer to perform online testing and monitor the propulsion pressure or speed. The drill bit cuts into the cave;
[0014] (3) The remote computer tests and monitors the rotary pressure online through the sensor, and when it exceeds the normal value, adjusts the rotary pressure to gradually increase the signal to control the pressure to drop steplessly;
[0015] ⑷For the stuck drill in the crack, control the computer to automatically prevent the rock drilling process.
