US 6,598,683 B1 · Portable injection-casing driver

Abstract

A driver tool provides an apparatus and method for installing shaft objects such as casing, pipes, poles, bars, rods, piles or tubes into the ground or other surrounding media. The driver tool has a steel tower on which is mounted a pneumatic or hydraulic hammer. The hammer is attached to a chain-driven mounting plate controlled by a hydraulic or air-driven motor so that the hammer slides in either direction along the tower. In a typical operating position, the tower is generally vertical to the ground and positioned over a shaft section so that the hammer can drive the shaft object into the ground at a manually controlled rate. The hammer and tower are mounted on a chassis having turf tires for rough terrain capability. In its transport position, the tool is positioned on its tires, with the tower generally horizontal to the ground. As a result, the driver tool can be easily moved and operated by one or two men and operated in limited access areas.

Dependent claims

A driver tool for hammering a shaft into a surrounding media comprising:

a base plate;
a tower attached to and extending generally perpendicularly from said base plate, said tower having a first end distal said base plate and a second end proximate said base plate;
a powered hammer movable along said tower between said first and second ends so that shaft can be positioned between said media and said hammer when said hammer is proximate said first end and so that said shaft can be driven by said hammer into said media as said hammer is actuated and moved toward said second end;
a motor;
a mount retained by said tower so as to be movable along said tower, said hammer attached to said mount;
and
a link installed between said tower first and second ends utilized to transfer mechanical energy from said motor to said mount so as to move said hammer, wherein said link comprises an upper sprocket proximate said first end, a lower sprocket proximate said second end, a reduction gear and a drive chain engaging said sprockets and said gear, said motor engaging said gear.
