Abstract
A walking foot for a drilling rig comprising a foot plate attacheable to a drilling rig by an travel plate, capable of functionally bearing a load in excess a quarter of the weight of a drilling rig, comprising a planar roller array wherein a plurality of load rollers with parallel rotational axes are dispersed both laterally and longitudinally within the plane, so as to fractionalize a weight applied perpendicular to the plane, and thereby promote longitudinal motion of the roller array in a direction perpendicular to the plurality of roller rotational axes.
Claims14
A walking foot for a drilling rig having a walking leg, comprising:
- a spindle attached to the walking leg;
- a foot plate;
- a travel actuator functionally attached to the spindle and the foot plate;
- a travel plate capable of functionally supporting a load in excess of a quarter of the weight of a drilling rig, the travel plate comprising:
- a planar roller array comprising a plurality of load rollers;
- the planar roller array having a line-of-travel;
- each said load rollers having a rotational axis;
- each of the plurality of load rollers mounted rotatably on a roller pin;
- the plurality of rotational axes being parallel to each other, and perpendicular to the line-of-travel;
- and
- the plurality of load rollers being dispersed within the planar roller array;
- the travel plate intermediate the spindle and the foot plate;
- and
- the travel plate fixedly attached to one of either the spindle and the foot plate, and rollably interfaceable with the other of the spindle and the foot plate.
