Definitions

  • the present invention relates to a capstan for handling cables, comprising a central hub provided with means of rotation about an axis D.
  • the invention finds an application in the general field of cable handling, and, more particularly, in that of handling fragile cables such as those used in marine seismic.
  • Marine seismic uses cables, called flutes, of great length which, in operational configuration, are submerged and towed by a ship. At rest, the flutes are stored on drums installed on the deck aft of the ship.
  • a capstan for handling cables comprising a central hub provided with means for rotation about an axis, said capstan comprising, at the periphery of said central hub, a plurality of modules each comprising a conveyor belt disposed between two parallel cylinders, all of the conveyor belts forming a drum for said capstan and said drum having a winding zone intended to receive turns a cable, one of the cylinders of each recentering module, called the drive cylinder, being driven by a motor so as to move said conveyor belt parallel to the axis of rotation of the central hub to control the position of the cable relative to the drum winding area.
  • the first layers of coiled cables undergo significant permanent stresses which are due to the winding traction of the cable, to the pressure exerted by the succession of the layers of turns, to the significant curvature to the diameter of the drum barrel, and finally to the connecting elements of the lengths of flutes.
  • These junction elements of larger diameter, generate additional point stresses detrimental to the components of the streamer cables, and this all the more so as the technology in the field of marine seismics evolves in the direction of better performance, but also of a greater fragility of the internal elements of the flutes.
  • An ideal solution would be to store the cables inside the vessel, on a drum, in a well or in bulk, under optimal conditions, that is to say without excessive constraints or bends. It still remains to design a handling means for bringing, and vice versa, the cable from its operational configuration to its storage configuration.
  • the technical problem to be solved by the object of the present invention is to produce a capstan for handling cables, in accordance with the preamble, which, in a reduced footprint, would be suitable for handling cables of new technology, without introducing stresses or bends incompatible with the fragility of the components used.
  • the invention provides a capstan for handling cables, comprising a central hub provided with means of rotation about an axis, said capstan comprising, at the periphery of said central hub, a plurality of refocusing modules comprising, each, a conveyor belt disposed between two parallel cylinders, the set of conveyor belts forming a drum for said capstan and said drum having a winding zone intended to receive turns of a cable, one of the cylinders of each module centering, said drive cylinder, being driven by a motor so as to move said conveyor belt in parallel to the axis of rotation of the central means for controlling the position of the cable relative to the winding zone of the drum, characterized in that it further comprises a feeler which, when the cable laterally exceeds a determined average position, controls a power supply box for the drive motor, to center the turns of the cable.
  • the capstan of the invention does not include cheeks, it is possible to increase the diameter of the drum in order to limit the stress on the constituent elements of the cables. Likewise, the stress on the cables is low, since it is exerted only during the passage over the drum during winding, the storage phase then being carried out with a reduced stress in maintaining the stretched strand.
  • the control of the drive motors by the device for controlling the position of the cable during winding makes it possible to maintain the turns present on the drum in the winding zone, generally the central part of the conveyor belts, despite the phenomenon of pitch screw generated by the winding. This position correction being carried out synchronously, no particular constraint is applied to the cables during the recentering.
  • Figure 1 is a perspective view of a capstan according to the invention.
  • FIG. 2 is a side view of a module for refocusing the capstan of FIG. 1.
  • FIG. 3 is a section through the conveyor belt of the refocusing module of FIG. 2.
  • FIG. 4 is a side view of a cylinder of the refocusing module of FIG. 2.
  • Figure 5 is a side view of a capstan according to the invention provided with a pivot means.
  • FIG. 6 is a top view of the rear deck of a ship on which the capstan of FIG. 5 is installed.
  • Figure 7 is a view similar to that of Figure 6 in which the capstan is coupled to a storage winch.
  • Figure 8 is a side view of a capstan according to the invention provided with a pressure wheel.
  • FIG. 1 shows in perspective a capstan 10 for handling a cable 100, comprising a central hub 200 provided with means of rotation about an axis D constituted by a hydraulic motor 210, for example with cams, mounted directly without reducer on the shaft 220 of said central hub 200.
  • a hydraulic motor 210 for example with cams
  • the hydraulic motor 210 is fitted with safety valves calibrated for the maximum permissible torque by the cable 100.
  • the capstan 10 stops at the set torque and can even deviate to avoid any abnormal effort on the cable.
  • the speed of the capstan is independent of the load, even when turning with reduced torque.
  • the capstan 10 comprises, at the periphery of the central hub 200, a plurality of refocusing modules 300, a side view of one of which is given in FIG. 2.
  • Each module recentering comprises a conveyor belt 310 arranged between two parallel cylinders 321 and 322.
  • all of the conveyor belts 310 form a drum for the capstan 10.
  • This drum is intended to receive in a winding zone Z a limited number of turns 110 of the cable 100, 4 in the case of FIG. 1, this number not being imperative.
  • Said winding zone Z will generally, but not exclusively, be situated around the median plane of the drum, that is to say in a central zone of the conveyor belts 310.
  • one of the cylinders 321 of each refocusing module 300 is coupled to a drive motor 330 shown in FIG. 1.
  • This drive motor 330 can be a hydraulic motor capable of moving the conveyor belts parallel to the axis D of rotation of the central hub, in both directions as required.
  • a device 410, 420 for controlling the position of the cable 100 during winding controls, synchronously, said drive motors 330 so as to move the conveyor belts 310 of refocusing modules 300 in order to maintain , by refocusing effect, the turns 110 in the zone Z for winding the capstan drum 10.
  • This refocusing is carried out independently of the direction of rotation of the capstan (winding or unwinding).
  • said position control device comprises a probe 410 which controls a housing 420 for synchronous supply of the drive motors 330 when the cable 100 laterally exceeds a determined average position.
  • the direction of supply of the motors 330 depends on the turning or turning function with respect to the theoretical winding zone (central zone) of the capstan drum.
  • the speed of movement of the conveyor belts is independent of the speed of rotation of the capstan. It is a function of the angular position of the 410-420 control device.
  • the control proportional to the angle, makes it possible to obtain a very flexible variation of correction with a speed which tends towards zero at the ideal winding position. This technique allows rapid correction of the position in the case of a transient offset phenomenon.
  • the position control device described with reference to FIG. 1 makes operation independent of the diameter of the cable 100 to be wound up and of punctual variations in shape over the length, due for example to the connection elements.
  • the large diameter of the capstan drum 10 has the advantage of generating a very reduced speed of movement of the strips 310.
  • each conveyor belt 310 comprises, for example, 4 toothed belts 311 separated by trapezoidal guide spacers 312.
  • the belts 311 and the spacers 312, made in particular of polyurethane, are covered with a flexible elastomer 313 with a high coefficient of adhesion to allow winding without risk of deterioration of the fragile elements of the cable and to prevent slipping of the cable during winding.
  • the elastomeric coating 313 has a slightly convex profile in the convex direction so as to reconstitute the diameter of the capstan drum to be produced.
  • Figures 2 and 4 show that the toothed belts 311 cooperate with longitudinal notches 330 arranged on said cylinders 321, 322 to ensure the longitudinal drive of the strip 310 according to the conventional principle of a belt.
  • the guide spacers 312 cooperate with annular grooves 340 formed in the cylinders in order to allow the longitudinal guidance of the conveyor belt 310 and to resist the transverse sliding of the belt caused by the starting acceleration during the formation of the first turn.
  • each refocusing module 300 comprises a fixed counter plate 350 on which the conveyor belt 310 slides, as illustrated in FIGS. 2 and 3.
  • This counter plate 350 can be a polished metal plate.
  • the hydraulic motor 210 for rotating the capstan preferably includes a backpressure valve on the motor circuit to allow, in a turning or turning configuration, to control the inertia of the drum and to maintain, by forced unwinding on the motor , the cable tension during storage or destocking.
  • the capstan 10 further comprises a means 500 for pivoting around a direction ⁇ orthogonal to the axis D of rotation.
  • the pivoting means 500 is formed by a stirrup fixed to the capstan 10 and connected at its ends to fixed points by straps 510, 520. It can also be observed in FIG. 5 that the the pivot axis ⁇ passes through the point T of tangency, at the winding, of the fiber leaving the cable 100.
  • the capstan of the invention thus made orientable can follow angular variations of the order of 10 to 20 °, which has the advantageous effect of limiting the transverse forces on the refocusing modules resulting from a difference between the effective direction of the cable and nominal direction of unwinding / winding of the capstan.
  • the tension of the cable 100 on the capstan 10 may be sufficient to prevent the capstan from pivoting about the axis ⁇ under the action of rolling by example.
  • the tension on the capstan is less so that the latter becomes more sensitive to roll and can therefore pivot freely with the danger that this represents for personnel responsible for maneuvering the capstan.
  • said pivot means 500 is provided with means for limiting the amplitude of pivoting, provided, for example, by a hydraulic feedback brake.
  • a mechanical assembly integrating the sensors 410 and 420 equipped at its end with an open fairlead 800 consisting of 3 rollers for example will serve as the cable entry on board.
  • This fairlead 800 will be fitted with sensors integrated in a loop for correcting the angular position of the assembly with the direction of the cable in the water.
  • the capstan according to Figures 5 and 6 can be coupled to a winch 600 for storing the cable 100 on wherein said cable is wound under a constant fixed tension.
  • the capstan 10 comprises means for lateral displacement of the pivoting means 500 parallel to the storage winch 600. These means consist of guide tracks 530 in which the straps 510, 520 can slide under the action of a hydraulic synchronous motor.
  • FIG. 8 shows an embodiment of the capstan of the invention which is particularly advantageous in that it comprises a pressure wheel 700 pressing on said capstan 10 substantially at the point T of tangency, on winding, of the fiber. outgoing from cable 100, the linear speed of said pressure wheel being at least equal to the linear speed of the capstan.
  • This arrangement enables the cable to be pressed against the recentering modules, in particular at the end of winding and at the start of unwinding.
