HYDRAULIC ROTATOR CONVERTER FOR A HYDRAULIC IMPACT HAMMER AND METHOD

摘要

A hydraulic rotator converter for attachment to a hydraulic impact hammer having a hammer housing and a hydraulic piston. The converter has mounting brackets, a rotator housing, posts attached to the rotator housing and attachable to the mounting brackets, a hydraulic rotator assembly including a hydraulic rotator, a rotator wheel driven by the hydraulic rotator, and a rotator plate connected to the rotator wheel, the rotator plate having a central cutout region formed therein, and a rotator drill bit dimensioned to pass through a central cutout region of the rotator plate and to engage with the central cutout region so as to be rotatable by the rotator wheel while allowing the rotator drill bit to move in an axis perpendicular to a longitudinal axis of the drill bit.

1. A hydraulic rotator converter for attachment to a hydraulic impact hammer having a hammer housing and a hydraulic piston comprising:
mounting brackets configured to attach to the hammer housing; a rotator housing having a cavity formed therein; posts attached to the rotator housing at a first end of each post, each post having a second end for removable connection to one of the mounting brackets; a hydraulic rotator assembly mounted in the cavity of the rotator housing, the assembly including a hydraulic rotator, a rotator wheel with a central opening, the rotator wheel driven by the hydraulic rotator, and a rotator plate connected to the rotator wheel, the rotator plate having a central cutout region formed therein; and a rotator drill bit having a drilling end and a second end, the drill bit positioned in the hammer housing so as to be contacted by the hydraulic piston, the rotator drill bit dimensioned to pass through the central cutout region of the rotator plate and the central opening of the rotator wheel and to engage with the central cutout region of the rotator plate so as to be rotatable by the rotator wheel while allowing the rotator drill bit to move in an axis perpendicular to a longitudinal axis of the drill bit.
