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:
at least one stake implement located on a side of the drill carriage;
and
a pair of hydraulic cylinders coupled to the at least one stake implement, wherein the pair of hydraulic cylinders are configured such that extension ranges of the pair of hydraulic cylinders are added together to select a depth of the at least one stake implement.

2. The directional drill of claim 1 , wherein the at least one stake implement includes multiple stake implements wherein all of the multiple stake implements are configured to be driven by the pair of hydraulic cylinders.

3. The directional drill of claim 1 , wherein the pair of hydraulic cylinders includes a first hydraulic cylinder with a piston facing up, and a second hydraulic cylinder with a piston facing down, wherein housings of the first and second hydraulic cylinders are coupled together.

4. The directional drill of claim 1 , wherein the at least one stake implement includes auger flights.

5. The directional drill of claim 4 , wherein the stakedown system further includes a hydraulic motor configured to rotate the at least one stake implement.

6. The directional drill of claim 5 , wherein the hydraulic motor is a single hydraulic motor configured to drive multiple stake implements.

7. 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 first pair of hydraulic cylinders coupled to the first stake implement, wherein the first pair of hydraulic cylinders are configured such that extension ranges of the first pair of hydraulic cylinders are added together to select a depth of the first stake implement;
a plurality of second stake implements including auger flights located on a second lateral side of the drill carriage, opposite the first lateral side; and
a second pair of hydraulic cylinders coupled to the plurality of second stake implements, wherein the second pair of hydraulic cylinders are configured such that extension ranges of the second pair of hydraulic cylinders are added together to select a depth of the plurality of second stake implements.

8. The directional drill of claim 7 , 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.

9. The directional drill of claim 7 , wherein the first pair of hydraulic cylinders includes a first hydraulic cylinder with a piston facing up, and a second hydraulic cylinder with a piston facing down, wherein housings of the first and second hydraulic cylinders are coupled together.

10. The directional drill of claim 9 , wherein the second pair of hydraulic cylinders includes a third hydraulic cylinder with a piston facing up, and a fourth hydraulic cylinder with a piston facing down, wherein housings of the third and fourth hydraulic cylinders are coupled together.

11. The directional drill of claim 7 , further including a hydraulic motor configured to rotate the plurality of second stake implements.

12. The directional drill of claim 7 , wherein the first stake implement is one stake implement, and wherein the plurality of second stake implements is two stake implements.
