Abstract:
A drill rod clamping system for securing a drill rod in a selected position. The drill rod clamping system has a hollow spindle with an upper portion that defines axial slots and a base portion that defines at least one radial opening. A plurality of jaws are moveable radially inwardly to a drill rod gripping position and radially outwardly to a drill rod releasing position. Each jaw is received within a respective axial slot of the hollow spindle. An actuator moves the plurality of jaws between the drill rod gripping position and the drill rod releasing position. A compressed gas spring assembly exerts force on the actuator to close the jaws. A hydraulic operator exerts force on the actuator to overcome the force of the compressed gas spring assembly to open the jaws. The radial openings of the base portion of the spindle permit flushing of material flowing within the spindle.

Claim (Index 1):
A drill rod clamping system for securing a drill rod in a selected position, the drill rod clamping system having a longitudinal axis and comprising:\n a hollow spindle having a central bore, an inner surface, an outer surface, a base portion and an upper portion extending upwardly from the base portion relative to the longitudinal axis, wherein the upper portion defines a plurality of axial slots that extend between the inner and outer surfaces of the hollow spindle; a plurality of jaws coupled to the spindle and being moveable radially inwardly to a closed drill rod gripping position and radially outwardly to an open drill rod releasing position, wherein each jaw is at least partially received within a respective axial slot of the plurality of axial slots of the upper portion of the hollow spindle; an actuator configured to move the plurality of jaws between the closed drill rod gripping position and the open drill rod releasing position; a compressed gas spring assembly configured to exert sufficient force on the actuator to close the jaws of the drill rod clamping system; and a hydraulic operator configured to exert force on the actuator to overcome the force of the compressed gas spring assembly to effect opening of the jaws of the drill rod clamping system.
