Abstract
A clamp for a tubular hose or cable is disclosed. The clamp comprises a first clamp half, a second clamp half, and a hinge pin. The first clamp half has a first end and a second end and defines a first concave semi-cylindrical face. The first end of the first clamp half carries means for mounting the clamp. The second clamp half has a first end and a second end and defines a second concave semi-cylindrical face. The first clamp half and the second clamp half come together along a parting line and are retained together by a hinge pin. The clamp halves are provided with snap-in liners for easy use. Alternative mounts for mounting the clamp on subsea wire line or tubulars is also disclosed.
Claims3
A clamp for a tubular hose or cable, said clamp comprising
- a first clamp half having a first end and a second end and defining a concave semi-cylindrical face, the first end of the first clamp half carrying means for mounting the clamp;
- a second clamp half having a first end and a second end and defining a concave semi-cylindrical face,
- said first clamp and said second clamp coming together along a parting line,
- said first clamp half defining at least one hinge pin hole at a position between the first end and the semi-cylindrical surface,
- said second clamp half defining at least one hinge pin hole at a position near the first end,
- a hinge pin positioned through the hinge pin holes of the first clamp half and the second clamp half pivotally connecting the clamp halves so that the clamp halves come together in a face to face relationship to form a clamp assembly which defines at least one passage therethrough for clamping a cylindrical object, wherein said passage has a longitudinal axis which is parallel to a longitudinal axis of the hinge pin,
- wherein the second end of the first clamp half is defined by a first pair of spaced apart ears,
- wherein the second end of the second clamp half is defined by a second pair of spaced apart ears, said second pair of spaced apart ears being in juxtaposition with the first pair of ears when the clamp is in a closed position, and
- wherein the first end of the first clamp half forms a pair of spaced apart elbows extending generally transversely from the parting line and in a direction generally away from the second clamp half, an inner side of each of said elbows being contoured to clamp a side of a cable, and a boss extending transversely from the elbows in a direction generally along the parting line, said boss having an outer surface contoured to be received within a hollow extension leg, and the hollow extension leg mounted on the boss.
