Abstract
An apparatus for storing, rotating and feeding a high pressure hose, including: a first rotatable drum with a helical groove; a second rotatable drum; and at least one actuator for rotating the first and second drums. For rotation of the first and second drums in first and second opposite directions, respectively, a hose and a cable are coilable into the helical groove such that the hose is in compressive engagement with the cable and the first drum. For rotation of the first and second drums in the second and first directions, respectively, the hose is uncoilable from the first drum and displaceable beyond the apparatus and the cable is coilable about the second drum.
Claims9
A method for storing, rotating and feeding a high pressure hose, comprising:
- rotating, using at least one actuator for an apparatus, a first drum for the apparatus in a first rotational direction to coil the high pressure hose and a cable in a helical groove for the first drum;
- rotating, using the at least one actuator, a second drum for the apparatus in a second rotational direction, opposite the first rotational direction, to uncoil the cable from the second drum;
- compressively engaging the hose, the cable, and the helical groove, wherein the cable presses the hose radially inward to retain the hose in the groove;
- rotating, using the at least one actuator, the first drum in the second rotational direction to uncoil the high pressure hose and the cable from the helical groove and displace the high pressure hose from the first drum;
- and,
- rotating, using the at least one actuator, the second drum in the first rotational direction to coil the cable about the second drum.
A method for storing, rotating and feeding a high pressure hose, comprising:
- rotating, using at least one actuator for an apparatus, a first drum for the apparatus in a first rotational direction to coil the high pressure hose and a cable in a helical groove for the first drum such that the cable presses radially inward on the hose and thereby places the hose in compressive engagement with the first drum;
- rotating, using the at least one actuator, a second drum for the apparatus in a second rotational direction, opposite the first rotational direction, to uncoil the cable from the second drum;
- rotating, using the at least one actuator, the first drum in the second rotational direction to uncoil the high pressure hose and cable from the helical groove and displace the high pressure hose through an outlet element for the apparatus;
- rotating, using the at least one actuator, the second drum in the first rotational direction to coil the cable about the second drum;
- and,
- rotating, with the actuator, a threaded rod engaged with the outlet element such that the outlet element is aligned with a portion of the helical groove from which the hose is uncoiling or into which the hose is coiling.
