Full hydraulic and control systems application in open-cut mine Drill
The LWD-200B full hydraulic open cut mine drills hydraulic system uses a variable displacement pump with load sensing constant power, load sensitive electromagnetic proportional multi-way directional valve, high torque hydraulic motor overhead direct drive rotary head, a long stroke hydraulic cylinder and steel wire rope and pulley speed lifting system, hydraulic cylinder to drive the unloading rod mechanism, hydraulic motor driving crawler, double hydraulic cylinder lifting the drill frame mechanism, a hydraulic motor driven cable winding drum, hydraulic legs leveling method.Control system adopts the control handle and the PLC control mode, with real-time data acquisition, computer automatic recognition of lithology and closed loop feedback control and GPS precise positioning function, to achieving the automatic or manual drilling, specified depth or level drilling.Through the test of practice, it is a multifunctional, fully hydraulic, which is intelligent and efficient perforation equipment.
