Abstract

A directional drill securing device and associated methods are shown. Securing devices and methods shown include a plurality of staking devices on a single lateral side of a directional drill. Using examples shown, a lower force is required to drive multiple staking devices than would be needed for a larger staking device of equivalent area.

First claim

The invention claimed is:

1. A directional drill, comprising:
a drill carriage;
a rotating spindle coupled to the drill carriage, wherein the rotating spindle is adapted to translate along a surface of the drill carriage;
a stakedown system coupled to an end of the drill carriage, including:
a first stake implement including auger flights located on a first lateral side of the drill carriage; and
a plurality of second stake implements including auger flights located on a second lateral side of the drill carriage, opposite the first lateral side;
wherein at least two stake implements are angled towards each other, wherein the at least two angled stake implements are configured to converge beneath the drill stem axis at a distance between auger flights of about 0.5 and 1.0 times a flight diameter.

2. The directional drill of claim 1 , wherein the first stake implement includes a plurality of first stake implements located on the first lateral side.

3. The directional drill of claim 2 , wherein the plurality of first stake implements includes two first stake implements.

4. The directional drill of claim 1 , wherein the plurality of second stake implements includes two second stake implements.

5. A directional drill, comprising:
a drill carriage;
a rotating spindle coupled to the drill carriage, wherein the rotating spindle is adapted to translate along a surface of the drill carriage;
a stakedown system coupled to an end of the drill carriage, including a plurality of stake implements including auger flights located on both a first lateral side of the drill carriage and a second lateral side of the drill carriage; and
wherein the first lateral side of the drill carriage includes a larger number of stake implements than the second lateral side;
wherein at least two stake implements are angled towards each other, wherein the at least two angled stake implements are configured to converge beneath the drill stem axis at a distance between auger flights of about 0.5 and 1.0 times a flight diameter.

6. The directional drill of claim 5 , wherein the first lateral side of the drill carriage includes one stake implement.

7. The directional drill of claim 5 , wherein the second lateral side of the drill carriage includes two stake implements.

8. The directional drill of claim 7 , wherein the two stake implements each include an auger.

9. A method of operating a directional drill, comprising:
positioning a drill carriage and a rotating spindle coupled to the drill carriage along a drilling axis;
selecting an optional desired number of stake implements including auger flights from a plurality of stake implements located on both a first lateral side of the drill carriage and a second lateral side of the drill carriage wherein the first lateral side of the drill carriage includes a larger number of stake implements than the second lateral side; and
staking down the directional drill using the selected number of stake implements, wherein at least two stake implements are angled towards each other, wherein the at least two angled stake implements are configured to converge beneath the drill stem axis at a distance between auger flights of about 0.5 and 1.0 times a flight diameter.

10. The method of claim 9 , wherein selecting an optional desired number of stake implements includes selecting a single stake implement on the first lateral side of the drill carriage.

11. The method of claim 10 , wherein selecting an optional desired number of stake implements includes selecting two stake implements on the second lateral side of the drill carriage.

12. A directional drill, comprising:
a drill carriage;
a rotating spindle coupled to the drill carriage, wherein the rotating spindle is adapted to translate along a surface of the drill carriage;
a stakedown system coupled to an end of the drill carriage, including:
a first stake implement including auger flights located on a first lateral side of the drill carriage,
a second stake implement including auger flights located on a second lateral side of the drill carriage, opposite the first lateral side; and
wherein the first stake implement is angled with respect to the second stake implement;
wherein the first stake implement and the second stake implement are angled towards each other beneath a drill stem axis;
wherein the first stake implement and the second stake implement are angled towards each other within a plane;
wherein the plane is oriented substantially perpendicular to a ground surface;
wherein the first stake implement and the second stake implement are configured to converge beneath the drill stem axis at a distance between auger flights of about 0.5 and 1.0 times a flight diameter.
