Hydraulic core drilling rig is a new rig, absorb the vertical shaft in the core and rotary core drilling rig structure developed on the basis of merit. Has produced a hydraulic core drill main advantages are: to be a long process, can reduce the auxiliary time during drilling, the hole will help to reduce accidents; power head to move along the slide to the more rigid, so oriented, good orientation, rotation, smooth; drill down into the agencies and institutions to one, the power head and the orifice holder can be achieved with the drilling screw unloading, this structure simplifies the structure of the rig and ancillary equipment. Hydraulic core drill also has a step less, speed range, overload performance, can be automated, remote automatic control and so on. However, hydraulic core drill a larger power consumption, transmission efficiency is low, removable poor, the high accuracy of hydraulic components, easy maintenance.
The drilling rig ready when the piston rod through the base will be flat on the base of the working bodies of rotation 90 °, softened hydraulic legs, and adjust the smooth and reliable, then you can drill vertical holes. Drill installation is completed, power. At this point, the drill chuck clamping, gripping is in release state. Power output of the power head, the hydraulic system driven by hydraulic motor rotates the motor output shaft in the gear shaft, the gearbox, the power to the hollow output shaft. Hollow shaft connected to drive rotation of the chuck at the same speed, thus rotating drill pipe. Coupled into the body adjust to the appropriate hydraulic pressure to complete drilling work drill
