FAST TRANSPORTABLE DRILLING RIG SYSTEM |
摘要 |
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.
