 Cable spooling system

Details

Primary Examiner: Werner; David

Attorney, Agent or Firm: O'Reilly; David

A stationary or mobile cable spooling system for winding up electrical cables used on drilling rigs comprised of an axle for insertion into a cable spool, a yoke for rotationally mounting the axle, a hydraulic motor coupled to the axle for rotating the spool and a cable guide system which evenly winds the cable onto the spool. The cable guide system is comprised of a cable guide mounted on a diamond grooved shaft which traverses from one side of the shaft to the other guiding the cable onto the spool. The hydraulic motor is driven by a pressure compensated hydraulic pump which prevents excessive force being applied to the cable as it is being wound on a spool. If the cable should catch or bind in any fashion and the stress on the cable exceeds a certain amount, the hydraulic motor will slowly stop when the pressure in the hydraulic pump exceeds a pre-determined amount. The transportable spooling system is comprised of a tiltable frame having the spooling system mounted on a trailer for transporting the system by towing it from one site to another. The tilt frame is tilted up and locked for transportation and is tilted down to provide a stationary platform for use at a site.

DETAILED DESCRIPTION What is claimed is: 1.
An electronic cable spooling system for spooling fragile electronic cables comprising; frame means; axle means for mounting a cable spool; support means on said frame means for rotatably supporting said axle with said cable spool; drive means for rotatably driving said axle and cable spool, said drive means comprising; pressure compensated hydraulic pump means; a hydraulic motor; hydraulic valve means connecting said pressure compensated hydraulic pump means to said hydraulic motor; said pressure compensated hydraulic pump means having preselected self-compensation of the rotational torque applied to said axle and cable spool; cable guide means guiding an electronic cable onto said cable spool for storage; whereby said drive means is carefully controlled to maintain a torque on an electronic cable substantially below a level which would cause damage; said drive means stalling when the torque required to wind said cable exceeds the preselected self-compensation of the rotational torque of said pressure compensating pump.
2.
The cable spooling system according to claim 1 in which said axle mounting means comprises; a pair of hinge yokes on opposite sides of said frame means; axle bearing means on each of said yokes; yoke latch means on each of said yokes constructed to open for removal of said axle; whereby said axle may be inserted into a cable spool and then mounted in said yokes and latched to secure said axle and cable spool.
3.
The cable spooling system according to claim 2 in which said drive means includes selective engagement means for engaging or disengaging said hydraulic motor from said axle.
4.
The cable spooling system according to claim 3, wherein said selective engagement means comprises; coupling means attached to the end of said axle; slidable coupling engagement means attached to the end of a torque hub shaft driven by said hydraulic motor means whereby said axle may be selectively engaged or disengaged from said hydraulic motor means
