First Claim
1. A drilling rig assembly comprising:
- a collapsible substructure movable between stowed and deployed positions, the collapsible substructure including;
a base box;
a drill floor framework;
a drill floor above the drill floor framework; and
a plurality of legs having ends pivotally connected to the base box and drill floor framework, the legs supporting the drill floor above the base box in the deployed position;
a mast having a lower mast section pivotally connected above the drill floor, and movable between a generally horizontal position to a position above the drill floor;
a cantilever having a lower end and an upper end, the lower end being pivotally connected to the drill floor framework, the upper end movable between a stowed position below the drill floor and a deployed position above the drill floor;
a raising cylinder pivotally connected at one end to the base box and having an opposite articulating end;
the raising cylinder being selectively extendable relative to the pivotal connection at the base box;
the articulating end of the raising cylinder connectable to the mast such that extension of the raising cylinder moves the mast from a generally horizontal position above the drill floor to a position above the drill floor; and
,the articulating end of the raising cylinder connectable to the upper end of the cantilever such that extension of the raising cylinder raises the drilling substructure into the deployed position.

Abstract
The present invention discloses a high-capacity drilling rig system that includes novel design features that alone and more particularly in combination facilitate a fast rig-up and rig-down with a single set of raising cylinders and maintains transportability features. In particular, a transport trailer is disclosed having a first support member and a drive member which align the lower mast portion with inclined rig floor ramps and translate the lower mast legs up the ramps and into alignment for connection. A pair of wing brackets is pivotally deployed from within the lower mast width for connection to the raising cylinder for raising the mast from a horizontal position into a vertical position. A cantilever is pivotally deployed from beneath the rig floor to a position above it for connection to the raising cylinder for raising the substructure from a collapsed position into the erect position.
