Abstract

A cylinder protection device for a cylinder of a machine includes a cylindrical body. The cylinder protection device includes a first portion having a first surface and a second surface. The first and second surfaces are disposed between a first end and a second end of the first portion. The first and second surfaces are inclined relative to each other. Further, the first and second surfaces intersect at a first upper edge of the first portion. The cylinder protection device also includes a second portion disposed on the cylindrical body and connected to the second end of the first portion. The second portion includes a third surface and a fourth surface inclined relative to each other. Further, the third and fourth surfaces intersect at a second upper edge of the second portion. The second upper edge is inclined relative to the first upper edge of the first portion.

Claims

1. A cylinder protection device for a cylinder of a machine, the cylinder including a cylindrical body, the cylinder protection device comprising:

a first portion disposed on the cylindrical body and including a first surface and a second surface, the first and second surfaces disposed between a first end and a second end of the first portion, wherein the first and second surfaces are inclined relative to each other, the first and second surfaces intersecting at a first upper edge of the first portion; and

a second portion disposed on the cylindrical body and connected to the second end of the first portion, wherein the second portion includes a third surface and a fourth surface inclined relative to each other, the third and fourth surfaces intersecting at a second upper edge of the second portion, wherein the second upper edge is inclined relative to the first upper edge of the first portion.

2. The cylinder protection device of claim 1, wherein the cylindrical body defines an upper portion and a lower portion with respect to a central axis of the cylindrical body, wherein the cylinder protection device is removably coupled to at least one of the upper portion and the lower portion of the cylindrical body.

3. The cylinder protection device of claim 1, wherein each of the first surface and the second surface include at least one of a concave surface and a planar surface.

4. The cylinder protection device of claim 1, wherein the first portion of the cylinder protection device tapers from the first end towards the second end.

5. The cylinder of claim 1, wherein the first portion of the cylinder protection device tapers from the second end towards the first end.

6. The cylinder protection device of claim 1, wherein the cylinder protection device has a uniform height along a length of the first portion.

7. The cylinder protection device of claim 1, wherein the second upper edge of the second portion extends from the first upper edge of the first portion towards the cylindrical body.

8. The cylinder protection device of claim 1, wherein the second upper edge of the second portion includes at least one of a concave edge and a straight edge.

9. The cylinder protection device of claim 1, wherein each of the third surface and the fourth surface include at least one of a concave surface and a planar surface.

10. The cylinder protection device of claim 1, wherein the cylinder protection device is manufactured from at least one of a plastic and a metal.

11. The cylinder protection device of claim 1, wherein the cylinder protection device is coupled to the cylindrical body using at least one of adhesives, hook and loop fasteners, epoxy, and mechanical fasteners.

12. A linkage assembly associated with a machine, the linkage assembly comprising:

a lift arm having a first end and a second end, wherein the first end is connected to the machine;

an implement member connected to the second end of the lift arm;

at least one cylinder adapted to move at least one of the lift arm and the implement member, the at least one cylinder including a cylindrical body; and

a cylinder protection device coupled to the cylindrical body of the at least one cylinder, the cylinder protection device comprising;

a first portion including a first surface and a second surface, the first and second surfaces disposed between a first end and a second end of the first portion, wherein the first and second surfaces are inclined relative to each other, the first and second surfaces intersecting at a first upper edge of the first portion; and

a second portion connected to the second end of the first portion, wherein the second portion includes a third surface and a fourth surface inclined relative to each other, the third and fourth surfaces intersecting at a second upper edge of the second portion, wherein the second upper edge is inclined relative to the first upper edge of the first portion.

13. The linkage assembly of claim 12, wherein the cylindrical body defines an upper portion and a lower portion with respect to a central axis of the cylindrical body, wherein the cylinder protection device is removably coupled to at least one of the upper portion and the lower portion of the cylindrical body.

14. The linkage assembly of claim 12, wherein each of the first surface and the second surface include at least one of a concave surface and a planar surface.

15. The linkage assembly of claim 12, wherein each of the third surface and the fourth surface include at least one of a concave surface and a planar surface.

16. The linkage assembly of claim 12, wherein the cylinder includes at least one of a hydraulic cylinder and a pneumatic cylinder.

17. A machine comprising:

a frame; and

a linkage assembly coupled to the frame of the machine, the linkage assembly comprising;

a lift arm having a first end and a second end, wherein the first end connected to the machine;

an implement member connected to the second end of the lift arm;

at least one cylinder adapted to move at least one of the lift arm and the implement member, the at least one cylinder including a cylindrical body; and

a cylinder protection device coupled to the cylindrical body of the at least one cylinder, the cylinder protection device comprising;

a first portion including a first surface and a second surface, the first and second surfaces disposed between a first end and a second end of the first portion, wherein the first and second surfaces are inclined relative to each other, the first and second surfaces intersecting at a first upper edge of the first portion; and

a second portion connected to the second end of the first portion, wherein the second portion includes a third surface and a fourth surface inclined relative to each other, the third and fourth surfaces intersecting at a second upper edge of the second portion, wherein the second upper edge is inclined relative to the first upper edge of the first portion.

18. The machine of claim 17, wherein the cylindrical body defines an upper portion and a lower portion with respect to a central axis of the cylindrical body, wherein the cylinder protection device is removably coupled to at least one of the upper portion and the lower portion of the cylindrical body.

19. The machine of claim 17, wherein each of the first surface and the second surface include at least one of a concave surface and a planar surface.

20. The machine of claim 17, wherein each of the third surface and the fourth surface include at least one of a concave surface and a planar surface.
