Abstract
An isolation system includes at least one air bladder assembly including at least one air bladder. The isolation system can also include at least one coupling member coupling the air bladder assembly to a drill head. The air bladder is configured to compress and expand to counter oscillating forces generated by the drill head.
Claims25
An isolation system, comprising:
- a mount assembly adapted to be secured to a support structure;
- at least one rail moveably coupled to said mount assembly, said at least one rail being adapted to be fixedly coupled to a vibratory drill head;
- and
- at least one air bladder assembly including at least one air bladder, said at least one air bladder assembly being coupled to said at least one rail and said mount assembly;
- wherein said at least one air bladder is configured to compress and expand to counter oscillating forces generated by the vibratory drill head as said at least one rail translates relative to said mount assembly.
2 more elements
A drilling system, comprising:
- a mount assembly;
- at least one rail coupled to said mount assembly;
- a drill head configured to generate oscillating forces, said drill head being fixedly coupled to said at least one rail;
- and
- an isolation system including at least one air bladder assembly having at least one air bladder;
- wherein said at least one rail is configured to transmit oscillating forces generated by said drill head to said at least one air bladder such that said at least one air bladder counters said oscillating forces.
3 more elements
A drilling system, comprising:
- a drill head configured to generate oscillating forces;
- a mount assembly;
- and
- an isolation system including at least one upper air bladder and at least one lower air bladder, wherein said at least one upper air bladder is coupled to said mount assembly on a first side of said drill head, and wherein said at least one lower air bladder is coupled to said mount assembly on a second, opposing side of said drill head;
- wherein said at least one upper air bladder is adapted to compress upon movement of said drill head away from said at least one upper air bladder to counter the oscillating forces.
2 more elements
An isolation system, comprising:
- a mount assembly adapted to be secured to a support structure;
- at least one rail guide adapted to be moveably coupled to said mount assembly, said at least one rail guide-being adapted to be coupled to a vibratory drill head;
- at least one air bladder assembly including at least one air bladder, said at least one air bladder assembly being adapted to be coupled to said at least one rail guide and said mount assembly;
- and
- a first bracket and a second bracket, said first bracket being positioned on an opposing side of said at least one air bladder as said second bracket;
- wherein:
- said at least one air bladder is configured to compress and expand to counter oscillating forces generated by the vibratory drill head as said at least one rail guide translates relative to said mount assembly, and
- said first bracket is positioned outwardly of said second bracket relative to the drill head and wherein said second bracket is held stationary relative to said first bracket.
5 more elements
A drilling system, comprising:
- a mount assembly;
- at least one guide rail coupled to said mount assembly;
- a drill head configured to generate oscillating forces, said drill head being fixedly coupled to said at least one guide rail;
- an isolation system including at least one air bladder assembly having at least one air bladder;
- at least one first bracket coupled to said at least one guide rail;
- and
- at least one second bracket configured to be held stationary relative to said at least one first bracket;
- wherein:
- said at least one guide rail is configured to transmit oscillating forces generated by said drill head to said at least one air bladder such that said at least one air bladder counters said oscillating forces,
- said at least one air bladder is positioned at least partially between said at least one first bracket and said at least one second bracket, and
- said drill head includes a casing and wherein said at least one guide rail passes through said casing and is coupled to said at least one first bracket of said first air bladder assembly.
