Abstract

A stabilizer for a line may include a guide configured for arrangement on the line to resist and/or damp lateral motions of the line where the guide may include a guide jacket having a static sleeve configured to allow the line to pass through the guide and a fortifying bracket configured to reinforce the guide jacket and configured to interface with a hanging system to support the guide jacket and maintain the guide jacket in position on the line.

First claim

What is claimed is:

1. A guide for damping lateral motion of a line, the guide comprising:
a central body portion, comprising:
a pair of body components configured to align to form a sleeve having a central opening to allow the line to pass through the guide; and
a pair of liner components housed within the sleeve and configured to align to form a sleeve liner having a central opening to allow the line to pass through the guide, each liner component having a groove configured to provide a break point in the event of a failure of the liner, the grooves arranged on an outer surface of the liner and at a location along a length of the liner closer to a first end than a second end such that, in the event of a failure at the break point, a majority of the liner component will remain within the sleeve; and

a pair of flanges extending laterally from each body component, the flanges of one body component configured to align with the flanges of an opposing body component.

2. The guide of claim 1 , wherein the pair of liner components is a first pair of liner components, and the guide further comprises a second pair of liner components housed within the sleeve and configured to align to form a second sleeve liner having a central opening to allow the line to pass through the guide.

3. The guide of claim 2 , wherein the first pair of liner components is arranged within an ingress opening of the sleeve formed by the body components, and the second pair of liner components is arranged within an egress opening of the sleeve formed by the body components.

4. The guide of claim 1 , wherein the pair of liner components comprises a wear mark arranged about central opening of the sleeve liner, and configured to indicate an amount of wear experienced by the guide.

5. The guide of claim 1 , further comprising a hinged connection between the body components.

6. The guide of claim 1 , further comprising a hang line assembly.

7. The guide of claim 6 , wherein the hang line assembly comprises a triangle cabling setup operably configured to allow the guide to move side-to-side.

8. The guide of claim 7 , wherein the line is a line being spooled on and off a winch drum and the triangle cabling setup is configured to allow the guide to travel back and forth parallel to an axis of the winch drum.

9. The guide of claim 1 , wherein each body component comprises a pair of standoffs, the standoffs of one body component configured to align with the standoffs of an opposing body component.

10. The guide of claim 1 , wherein the liner comprises an aluminum-bronze alloy.

11. A method of damping lateral motion of a line, the method comprising:
arranging a guide around the line, the guide comprising:
a central body portion, comprising:
a pair of body components configured to align to form a sleeve having a central opening to allow the line to pass through the guide; and
a pair of liner components housed within the sleeve and configured to align to form a sleeve liner having a central opening to allow the line to pass through the guide, each liner component having a groove configured to provide a break point in the event of a failure of the liner, the grooves arranged on an outer surface of the liner and at a location along a length of the liner closer to a first end than a second end such that, in the event of a failure at the break point, a majority of the liner component will remain within the sleeve; and

a pair of flanges extending laterally from each body component, the flanges of one body component configured to align with the flanges of an opposing body component; and

mechanically securing the body components to one another via the flanges.

12. The method of claim 11 , further comprising coupling the guide to a hang line assembly.

13. The method of claim 12 , wherein the hang line assembly comprises a triangle cabling setup operably configured to allow the guide to move side-to-side.

14. The method of claim 11 , wherein the guide is a first guide, the method further comprising arranging a second guide around the line.

15. The method of claim 14 , further comprising coupling the second guide to the first guide.

16. The method of claim 11 , further comprising removing and replacing the pair of liner components upon an indication of an amount of wear experienced by the liner.
