Abstract
An apparatus for changing a drilling tool for a drilling rig is described, where the drilling rig comprises a drill tower supporting a drill pipe. The apparatus for changing a drilling tool has a drilling tool changer assembly moveable between a storage position and an exchange position, and the drilling tool changer assembly supports a rotatable carousel assembly. The rotatable carousel assembly is capable of being removed from the drilling tool changer assembly and capable of replacement on the drilling tool changer in the same angular position with respect to the drill pipe as when removed. The rotatable carousel assembly has a plurality of bit adaptors for holding drilling tools and is selectively rotatable to bring a selected drilling tool into coaxial alignment with the drill pipe when the drilling tool changer assembly supporting the rotatable carousel assembly is moved into the exchange position.
