Portable coring machine

摘要

The present invention is a coring unit adapted to be engaged to an articulated arm, to reduce the labor necessary for on-site coring of sewage and water pipes. The coring unit includes a frame containing the components of the unit, which include a coring bit, a coring bit motor, a traverse mechanism, and a stabilizer for allowing ready orientation of the coring unit with respect to an object being cored. The unit may also be provided with a traverse motor for driving the coring bit into an object being cored, and for withdrawing the coring bit once a core has been formed. The coring unit may additionally be adapted to allow for remote operation of the coring unit.

主权项

1. A pipe coring unit, said coring unit being adapted to be engaged to an articulated arm, with said coring unit comprising:
a frame, a coring bit, a motor for rotating the coring bit, a traverse mechanism, a coolant sprayer, and a stabilizer mounted to said frame; wherein said coring bit is connected to said motor for rotating the coring bit; said coring bit further being mounted to said traverse mechanism; said traverse mechanism being fixed to said frame and having a traverse axis; and wherein said coring bit is oriented substantially parallel to said traverse axis; wherein said stabilizer orients said coring unit against a face of an object to be cored such that said traverse axis is substantially perpendicular to said face of said object; and wherein said frame is adapted to be engaged to an articulated arm by a first pin and a second pin, said first pin allowing rotation of the coring unit about a first axis of rotation fixed to said articulated arm, and said second pin adapted to be engaged to a positioning link, said positioning link for controlling rotation of the coring unit about said first axis of rotation to allow an articulated arm to which the coring unit is engaged to orient the coring bit in a horizontal axis, said positioning link positively controlling the orientation of the frame and coring bit with respect to the articulated arm.
