Abstract
This invention is directed toward a system for driving a wire loop cutting element. More particularly, the disclosed invention employs a frame and pulleys to drive a wire loop cutting element.
Claims20
A subsea system for driving a wire loop cutting element, comprising:
- a. a frame comprising a lower plate comprising right and left arms defining a lower central gripping region, said frame further comprising a bracket connected to the lower plate, and an upper plate connected to the bracket, said upper plate comprising two pulley slots, a right arm comprising a first drive wheel axle opening, and a left arm opposite the right arm, comprising a second drive wheel axle opening, said right and left arms defining an upper central gripping region in substantial longitudinal alignment with the lower central gripping region;
- b. a first drive wheel axle rotatably mounted in the first drive wheel axle opening;
- c. a first drive wheel coupled to the first drive wheel axle;
- d. a second drive wheel axle rotatably mounted in the second drive wheel axle opening;
- e. a second drive wheel coupled to the second drive wheel axle;
- f. a first drive wheel motor attached to the frame and operatively coupled to the first drive wheel axle;
- g. a second drive wheel motor attached to the frame and operatively coupled to the second drive wheel axle;
- h. a clamping device attached to the frame and positioned such that it can clamp objects to be cut in a fixed position in the central gripping regions;
- i. a first pulley comprising a first pulley axle mounted in the first pulley slot;
- j. a second pulley comprising a second pulley axle mounted in the second pulley slot;
- and
- k. a pulley positioning system attached to the first and second pulleys for varying the separation distance between the first and second pulleys.
