X-Y-Z pipe racker for a drilling rig
First Claim
1. An apparatus comprising:
- an x-direction support structure extending in the same direction as a line extending between a well center and a V-door on a drilling rig;
a y-direction support structure moveable relative to the x-direction support structure, the y-direction support structure extending on a drilling rig in a direction transverse to the line extending between the well center and the V-door on the drilling rig; and
a column racker device having a support column extending from an upper end to a lower end, the upper end being retained by one of the x-direction and the y-direction support structures, the lower end being supported on and moveable along floor constructs of the drilling rig, the racker device being configured to connect to and carry a tubular stand adapted for well drilling, the racker device being moveable along the y-direction support structure from a position inline with the line extending between the well center and the V-door on the drilling rig to a position offline from the line extending between the well center and the V-door on the drilling rig to provide space for additional drilling equipment along the line extending between the well center and the V-door on the drilling rig, the racker device comprising;
an upper carriage moveable along the support column, the upper carriage having an upper extending arm configured to selectively connect with a stand of pipe;
a lower carriage disposed at a location lower than the upper carriage, the lower carriage having a lower extending arm configured to selectively connect with the tubular stand; and
a lift system configured to raise and lower the upper carriage.

Abstract
Apparatus and methods include an x-direction support structure extending in the same direction as a line extending between a well center and a V-door on a drilling rig and include a y-direction support structure moveable along the x-direction support structure. The y-direction support structure extends on a drilling rig in a direction transverse to the line extending between the well center and the V-door on the drilling rig. A racker device is carried by the y-direction support structure and is configured to connect to and carry a tubular stand used in a well drilling process, the racker device being moveable along the y-direction support structure from a position inline with the line extending between the well center and the V-door on the drilling rig to a position offline from the line to provide space for additional drilling processes along the line extending between the well center and the V-door on the drilling rig.
