Abstract
An auger stand, system, and method of use thereof for lifting a longitudinal object. The auger stand comprises at least one wall section forming a hollow inner cavity for receiving an auger, a landing to support a load from the auger and provide an upward thrust, and a base for supporting the auger stand including an anchoring mechanism to prevent rotation of the auger stand. During operation, the auger is rotated in a first direction to screw into the auger stand and rotated in a second direction to unscrew from the auger stand and lift the longitudinal object. The auger stand may also be used as a cover to protect the auger and a stand to support the auger in an upright position.
Claims20
An auger stand for receiving an auger of a digger derrick system, the auger stand comprising:
- at least one wall section forming a hollow inner cavity configured to receive the auger therein;
- a landing secured to an interior surface of the at least one wall section within the inner cavity to support a load from the auger and provide an upward thrust,
- wherein the landing forms a shape corresponding to a blade of the auger;
- and
- a base for supporting the auger stand, the base comprising an anchoring mechanism to prevent rotation of the auger stand.
A method for lifting a longitudinal object using a digger derrick system including an auger, the method comprising the steps of:
- providing an auger stand comprising:
- at least one wall section forming a hollow inner cavity;
- a landing secured to an interior surface of the at least one wall section within the inner cavity;
- and
- a base comprising an anchoring mechanism;
- positioning a blade of the auger within the inner cavity of the auger stand such that a bottom surface of the blade is in direct contact with a top surface of the landing of the auger stand;
- securing the anchoring mechanism of the auger stand into the ground to prevent rotation of the auger stand;
- securing the longitudinal object to a distal end of a boom of the digger derrick system after the auger is screwed into the auger stand;
- and
- rotating the auger in an extraction direction opposite from a digging direction of the auger such that the blade of the auger is unscrewed from the auger stand to lift the longitudinal object.
A system for lifting a longitudinal object, the system comprising:
- a boom comprising a proximal end and a distal end;
- a digger assembly attached to the distal end of the boom, the digger assembly comprising:
- an auger;
- and
- a digger motor for driving rotation of the auger;
- and
- an auger stand configured to be placed over the auger of the digger assembly, the auger stand comprising:
- at least one wall section forming a hollow inner cavity configured to receive the auger therein;
- a landing secured to an interior surface of the at least one wall section within the inner cavity to support a load from the auger and provide an upward thrust,
- wherein the landing forms a shape corresponding to a blade of the auger;
- and
- a base for supporting the auger stand, the base comprising an anchoring mechanism to prevent rotation of the auger stand.
