Abstract
A device for cutting a length of pipe includes a clamp portion for clamping around a length of pipe and a bow moveable with respect to the clamp portion that retains a loop of diamond embedded wire. The device further includes a feed for driving the bow with respect to the clamp portion and a detector for detecting bending of the wire and a control responsive to the detector for controlling feed rates. The device is made of modular parts and has synchronizing arms for clamping around a length of pipe. In one embodiment, the wheels are retained in enclosures with slots through which the cutting wire passes.
Claims13
A device for cutting an object under water comprising
- a clamp that at least partially encircles said object for retaining said device to said object,
- a bow moveable with respect to said clamp,
- a plurality of wheels on said bow,
- a cutting wire loop on said wheels,
- an enclosure surrounding one of said wheels,
- said enclosure having a slot therein adjacent a portion of said one of said wheels wherein said cutting wire extends through said slot to an outer surface of said one of said wheels;
- said clamp includes a first and a second moveable arm for extending around said object for retaining said object,
- said first moveable arm driven by a first cylinder and said second moveable arm driven by a second cylinder,
- a mechanical synchronization between said first cylinder and said second cylinder wherein said first moveable arm and said second moveable arm move in unison to encircle said object,
- a frame, and
- said frame having a plurality of mountings located thereon for receiving one of said first and second moveable arms at any one of said plurality of mounting locations wherein said one of said first and second moveable arms will grasp a range of sizes of pipe at each of said mounting locations that is different from a range of sizes of pipe that can be grasped at any other of said plurality of mounting locations.

A device for cutting an object under water comprising
- a clamp that at least partially encircles said object for retaining said device to said object,
- a bow moveable with respect to said clamp,
- a plurality of wheels on said bow, wherein said plurality of wheels are rotatable relative to said bow,
- a cutting wire loop on said wheels,
- an enclosure surrounding one of said wheels, wherein said enclosure is fixed relative to said bow and said one of said wheels is rotatable relative to said enclosure, and
