Definitions

  • the present invention relates to winding cables or all other rollable elements, such as hoses, pipes, tubes or other profiles of which storage, in particular intermediate storage during operation, advantageously takes the form of a winding.
  • the storage of such elements is advantageously done in a storage basket, as described in application W0 95/31392, the content is part of this application.
  • the storage device described in the aforementioned application essentially comprises: a storage basket formed in particular by an external wall, disposed around the periphery of a bottom serving as a winding base, a guide means, a fixed laying means or rotary, intended to angularly drive the element to be wound from the guide means towards the storage basket, said device not comprising no motorized means of driving the laying means.
  • the laying means is rotary
  • the latter consists at least one tubular segment, essentially radial, extending from a place near one end of the guide means as far as the basket storage, said tubular segment being pivotable about a corresponding axis to the axis of the device.
  • this device comprises a means of adjustment in height of the end of the tubular segment in the basket.
  • the height adjustment means described in the aforementioned request is arranged on the axis of the device and acts on the entire laying means rotary, respectively of the tubular segment, which in the case considered is rigid. It is intended that this height adjustment means be controlled manually or automatically.
  • the order is manual, it requires a operator constantly attentive to the element being rolled up properly in the basket; this is an additional cost for very little work rewarding.
  • the order is automatic, it can be directly progressive, i.e. the height of the tubular segment increases regularly according to the quantity of element already stored, i.e. generally depending on the number of laps completed by the segment tubular. In this case, the height variation command report in depending on the number of turns must be adapted to the diameter or dimension of the element to be wound.
  • Another possibility is to raise the height of the quantity of item stored in the basket and order the height of the tubular segment according to this height raised in order to have a pose regular. This possibility requires height measurement means, costly probing or detection means respectively requiring complex equipment.
  • An object of the invention is therefore to propose an adjustment device in height of the laying means, respectively of the tubular segment does not meeting the mentioned drawbacks of the device described.
  • this height adjustment device is self-regulating, i.e. it is directly controlled by the element to wind, respectively the longitudinal stiffness of the element to be wound, which rests on the bottom of the storage basket or on the coils already stored.
  • the device self-regulating is associated with a means for adjusting the height of the assembly means of laying and controlling these, a sequential coarse adjustment being established by the latter while a fine adjustment is obtained by the device self-regulating.
  • Another object of the invention is to propose a storage device fitted with such a height adjustment device.
  • Yet another object of the invention is to propose a method of manufacture of an elongated element of great length using two devices storage as mentioned.
  • Another object of the invention is to propose uses particular of said storage device provided with a device for adjusting height as mentioned.
  • the storage basket 1 in Figure 1 is quite similar to that described as second embodiment in Figure 2 in the application cited above. It is essentially cylindrical in shape, having a cross section transverse to the X axis in the form of a circular crown. It consists essentially from a bottom 10, uniting two side walls, an outer wall 11 and an internal wall 12, these two walls being vertical or inclined. The bottom 10 and / or one or both walls 11 and 12 may have a surface full and uniform or a lattice surface. The outer wall 11 rises from the bottom 10 on which it is fixed, up to a given height, making it possible to provide lateral support for the cable to be wound up.
  • the outer wall 11 supports a first support structure 13, shown here in a conical shape and intended to support a guide means 14 able to pivot around a ring of pivoting guide 14A fixed coaxially to the axis X of the basket 1 on the structure support 13.
  • the internal wall 12 rises from the bottom 10, to which it is also fixed, up to a given height.
  • the inner wall supports another support structure 15, shown here in a conical shape, essentially serving to support the laying means 2 in rotation.
  • the laying means 2 here consist of a laying tube 20, the orifice of which upper 21 is coaxial with the X axis and opposite the lower orifice of the means of guide 14, respectively of the pivoting guide ring 14A, while the lower orifice 22 of the tube 20 is generally arranged in the space storage limited by the walls 11, 12 and the bottom 10.
  • the orifice 22 is oriented in general to allow correct winding of element 3 in said storage space during the introduction of the element into the device storage, as well as a correct course of said element during its extraction of said storage device.
  • the laying tube 20 is supported by a structure 23, fixed to a pivoting bearing 24 relative to the support structure 15.
  • the fitting means 2 further comprises a mass balancing as well as braking means (not shown) arranged in the bearing 24.
  • the laying means 2 are described here as being consist of a tube; we must understand that it can also be a assembly of a plurality of portions of tubes or rings arranged so as to guide the cable when it is placed in the, or when it is removed from the basket.
  • the storage basket 1, the means of pose 2 as well as the guide tube 14 are provided with opening means lateral, shown schematically by 16, 17, 17A, 24B, and 24A in the figure, allowing to introduce or laterally extract the cable from the system, these means can be closed, are described more specifically in the aforementioned application.
  • opening means lateral shown schematically by 16, 17, 17A, 24B, and 24A in the figure, allowing to introduce or laterally extract the cable from the system, these means can be closed, are described more specifically in the aforementioned application.
  • the device essentially corresponds to that described in the aforementioned application.
  • the height adjustment means 4 consists essentially of the lower portion 20A of the laying tube 20 which is pivotable about an axis Y coaxial with a central portion 20B of the length of the tube 20.
  • the laying tube 20 is provided with a pivoting lining 40 disposed between the portion central 20B of the tube 20 and its lower portion 20A.
  • the swivel packing 40 consists of two portions, 40A and 40B, fixed respectively to the portions 20A and 20B of the tube 20, pivoting means 41, for example with balls, allowing each of the two said portions to pivot between them, respectively at the lower portion 20A of the tube 20 of pivot around the central portion 20B of the same laying tube.
  • the pivoting lining 40 is also provided with an opening lateral 46, which can possibly be closed.
  • a cable drive means When loading the storage basket 1 with a cable 3, a cable drive means, not shown, pushes the cable into the tube guide 14, it comes out through the guide ring 14A to enter the laying tube 20 by its upper end 21 and out by its lower end 22 and go to rest on the bottom 10 of the storage basket 1.
  • this one supported from the inside of the portion close to the orifice 22 of the end portion 20A, pushes the laying tube 20 towards the rear, rotating it around the X axis, which leads to an installation in successive loops or turns of the cable 3 in the basket storage space storage.
  • the necessary height between the hole 22 of the lower end 20A of the tube 20 and the coil to be installed is no longer sufficient for correct installation. It is then that, still under the effect of the rigidity of the cable 3, the portion lower 20A of the tube 20 starts to pivot slightly around the Y axis, by the swivel fitting 40 described above, in order to maintain an installation height relatively constant. This movement therefore tends to raise the orifice 22 relative to the bottom 10 of the basket.
  • the trim pivoting is provided with compensation means 42, represented here by two counterweight, arranged so as to balance the proper mass of the portion of tube 20A around the axis Y.
  • the pivoting means 41 of the lining 40 may further be provided with pivoting braking means so dampen the pivoting movement of the tube portion 20A and avoid instabilities.
  • the portion of tube 20A is flared towards orifice 22, in the shape of a truncated cone or trumpet, so that the orifice 22 is always correctly aligned for correct laying of the cable 3.
  • the amplitude of adjustment possible by such a device essentially depends on the length of the bent portion of the portion of tube 20A closest to the orifice 22 as well as the opening angle of the truncated cone or the trumpet.
  • the height of the outlet orifice 22 of the lower portion 20A of the laying tube 20 is adjusted automatically, by the cable itself, respectively the rigidity of the cable, when it is placed in the storage space of the storage basket 1 by pivoting the lower end 20A of the tube laying around the Y axis.
  • the pivoting is done so as to raise the orifice 22 relatively at the bottom 10 of the basket during cable storage.
  • the device described is therefore self-regulating.
  • the means When removing the cable 3 from the storage basket, the means are operated in the opposite direction, pulling the cable out of the means guide 14, respectively out of the laying tube 20, causing the pose 20 automatically rotates in the opposite direction to that of pose.
  • the height of the orifice 22 is adjusted automatically, in this case by a pivoting of the lower end 20A tending to lower orifice 22.
  • Figure 2 shows a second embodiment of the device suitable for a higher capacity storage basket 1, respectively for which the walls 11 and 12 are higher than previously leaving therefore between them more storage space.
  • the only height adjustment of the orifice 22 of the laying tube 20 by pivoting the lower portion 20A by means of the swivel fitting 40 may not be sufficient to fit the entire height of the storage space.
  • a height adjustment means 43 is also provided, mounted on the bearing 24, capable of raising or lowering the entire laying tube 20 respectively along the X axis.
  • the height adjustment means 43 can be of the type mechanical, electrical or hydraulic, and is preferably ordered directly by the angular position of the lower portion 20A of the tube poses 20 around the Y axis.
  • the pivoting lining 40 is provided with a angular detection means 44, of known type, capable of recording the position angular around the Y axis of the portion 20A relative to the portion 20B of the laying tube 20 and to send a control signal via the link 45 to the height adjusting means 43.
  • the angular detection means can be consisting for example of two detectors, capable of detecting respectively a maximum angular offset position and an angular offset position minimum, the lower portion 20A can therefore pivot between these two positions, and to send an elevation control signal by means of height adjustment 43 when the first detector is activated, then a signal elevation stop when the second detector is activated.
  • the maximum angular offset position detector sending its signal, the height adjusting means 43 being activated by a certain value fixed.
  • the means height adjustment 43 fixing the laying tube 20 in the low position
  • a first adaptation of the height of the orifice 22 is obtained by the pivoting of the portion 20 A as before, and when the detector 44 detects that the pivoting has reached the maximum possible value for correct installation of the cable, it controls an elevation of the laying tube 20 by the means of height adjustment 43, said elevation causing the portion to pivot 20A in the opposite direction which returns to its starting angular position, until the end of the elevation of the laying tube 20, controlled by the second detector or ending after a given race.
  • Figure 3 shows a particular variant of the end portion 20A of the laying tube 20 when said laying tube, respectively the Y axis, extends perpendicular to the X axis, in the storage basket, i.e. generally horizontally, and not obliquely as shown in the two previous figures.
  • the portion 20A is flared as before, a simple portion of tube bent at 90 ° allowing the same height adjustment effect to be obtained.
  • This variant is adaptable to the two embodiments described.
  • Such a device for adjusting the height of the orifice 22 of the tube pose 20 is particularly suitable for a storage basket as described, that is to say in which the laying means does not include any motorized means drive, or where it is the cable due to its longitudinal rigidity which rotates said laying means.
  • the laying means does not include any motorized means drive, or where it is the cable due to its longitudinal rigidity which rotates said laying means.
  • An advantage of such a cable storage system is that, by having side openings on all the elements of the storage basket, it is possible to introduce or laterally remove the cable from said storage basket.
  • Figure 1 where such openings have been shown schematically by way of example, we sees an opening 16 on the outer wall 12 as well as on the structure of support 13, a lateral opening 17 of the guide tube 14 as well as another lateral opening 17A on the guide ring 14A, a lateral opening 24A on the portion 20A and a lateral opening 24B on the portion 20B of the tube fitting 20, as well as a lateral opening 46 on the pivoting lining 41.
  • a storage basket 1 according to either of the embodiments described above can be used for cable laying or rewinding operations as described in the aforementioned application.
  • a very long cable for example a submarine cable
  • a receiver for example a machine able to deposit a sheath of mechanical and / or protective armor.
  • One of ways to make the long cable is to make it elementary lengths, which are then assembled in succession by splices before going into the machine removing the armor sheath protection, which also protects the splices.
  • each elementary length is manufactured in length as large as possible to limit the number of splices, then rolled up on a large diameter drum.
  • FIGS. 4A to 4F show some steps of a method of manufacturing, using storage baskets according to the invention and allowing to eliminate these faults.
  • the machines are shown symbolically as seen above, there are two baskets of storage 1, represented respectively by 1A and 1B, a first machine of production, for example a machine 5 terminating the part of the cable 3 placed under the armor and an armor laying machine 6.
  • the meaning of cable production therefore goes from left to right in the figures.
  • the guide tube is shown 14 and in order not to overload the figures, the cable stored in the baskets is only represented by a limited number of turns.
  • the cable 3 produced by the machine 5 is stored in the storage basket 1A, its free end 30A emerging from the backplane. Basket 1B is empty.
  • the production machine 5 feeds the basket 1B, the free end 30B emerging at the bottom of the basket. Only the guide tube 14 of the basket 1A is oriented in the direction of the machine 6.
  • the upper end of the cable housed in the basket 1A is extracted by the guide tube 14 and is brought to the production machine 6 which can start its work, simultaneously, the upper end of the cable housed in the basket 1B is extracted by the guide tube 14 and is brought near the end lower 30A of the cable housed in the basket 1A for splicing 31.
  • the basket 1B continues to supply the machine 6 while the basket 1A is again recharged by the machine 5.
  • the basket 1B continues to supply the machine 6, the basket 1A being full the upper end of the cable it contains is brought opposite the lower end 30B of the cable contained in the basket 1B and a splice 32 is made between the two cables.
  • this sixth step corresponds exactly to the third step of FIG. 4C seen above, the basket 1A replacing the basket 1B and vice versa.
  • any other process necessary to obtain of an elongated element of great length, not necessarily a cable can be performed using two storage baskets as described previously.
  • a such a process when you absolutely cannot stop a machine, for example example machine 6 which could be a sheath extrusion line synthetic exterior.
  • this machine started in step of Figure 4C, it is that the time required for the machine 5 to fill a storage basket added to the time required for making the splice and that needed to exit laterally basket cable, less than that required for machine 6 to perform its sheathing operation over an elementary length stored in a basket.
