Abstract
A drill rig with a steering system may include a substructure having a wheelhouse, a drill floor arranged atop the substructure, a mast extending upwardly and above the drill floor, and a steering system arranged within the wheelhouse. The steering system may include a wheel assembly comprising an electric motor configured for driving rotational motion of a wheel, a deployment device configuring for deploying the wheel assembly to carry the drill rig, and a steering mechanism configured for selective engagement with the wheel assembly and rotating the wheel assembly.
Claims18
A steering system for a drill rig, comprising:
- a wheel assembly comprising a mechanism for driving rotational motion of a wheel;
- a deployment device configuring for deploying the wheel assembly to carry the drill rig;
- and
- a steering mechanism configured for selective engagement with the wheel assembly and rotating the wheel assembly while the wheel assembly is engaged with the ground.
A steering system for a drill rig, comprising:
- a wheel assembly comprising a mechanism for driving rotational motion of a wheel;
- a deployment device configuring for deploying the wheel assembly to carry the drill rig;
- a steering mechanism configured for selective engagement with the wheel assembly and rotating the wheel assembly;
- and
- a control system having a double-ended cylinder, wherein lateral motion of the double-ended cylinder imparts rotation on the wheel assembly,
- wherein, the steering mechanism provides for ratcheted steering of the wheel assembly, the ratcheted steering comprising steering in selected angular increments.
