Definitions
- the present invention relates to the winding and unwinding of a wire rope from a reel-type device.
- a drum which has the shape of a wheel comprising a central hub, radial spokes starting from the hub and having curved extensions which together form the rim of the wheel and define a housing substantially toroidal for the wire rope.
- This drum has also a circle passing through the free ends of the extensions, said circle delimiting the cable introduction and extraction zone.
- the axis of the hub of the reel is secured by one of its ends to a horizontal rod supported by a frame, said rod being able to pivot in two positions, a first position in which the hub is horizontal and a second position in which the hub is vertical with the circle for insertion and extraction of the cable directed upwards.
- An arm terminated by a cable passage eyelet is attached to the end of the hub opposite the horizontal rod.
- this known device does not make it possible to obtain reliably an optimal unwinding of a wire rope in the since during the course of the event, the formation of loops, due to a circumferential speed of the drum different from the actual unwinding of the cable.
- loop a turn which was in the toroidal housing of the drum and which escapes from it in this same configuration.
- it is essential to remedy it manually if not of the tensioning of the cable by any mechanical means, the cable will be chewable and unusable.
- the goal set by the applicant is to propose a process simple to implement a device of the drum type, for the winding and unwinding of a metallic cable which overcomes the aforementioned drawback, said reel having the shape of a wheel with a central hub, with a radial element or a plurality of radial spokes starting from the hub and having one or more curved extensions, the or the extensions forming the rim of the wheel and delimiting a substantially toroidal housing for the wire rope and with a circle passing through the free end (s) of said extension (s).
- the method consists, to unwind the cable, place the hub on a vertical axis mounted on a support, with the circle facing downwards at a short distance from said support, to pull the cable substantially horizontally and to unwind by letting it touch the vertical axis and the support. Traction on the cable at the start of unwinding leads it to touch the vertical axis, between the support and the hub. As soon as the reel rotation is synchronous with the unwinding of the cable, the cable no longer touches the axis. Finally, due to the contact between the portion of cable coming out of the drum and the support, braking is obtained which regulates the course. So usual the cable unwinding is done outdoors and the support on which is mounted the vertical axis is none other than the ground.
- It is another object of the invention to propose a installation for winding and unwinding a wire rope which comprises a drum in the form of a wheel with a central hub, with a radial member or a plurality of radial radii extending from the hub and having one or more curved extensions so that the or said extensions, forming the rim of the wheel, delimit a substantially toroidal housing for said metal cable and with a circle passing through the free end (s) of said one (s) extensions.
- the installation also includes a vertical axis of reduced height, mounted on a support; moreover the reel hub is able to be mounted on the axis vertical in a first position in which the circle is turned towards the top for winding the cable and a second position in which the circle is turned down for the unwinding of the cable.
- the vertical axis has a height such that the distance between the support and the equatorial plane of the toroidal housing is approximately twenty centimeters.
- the hub has a length which is less than or equal to half the diameter of the torus formed by the one or more curved extensions, said hub being disposed substantially symmetrically with respect to the equatorial plane of said torus.
- the hub has a length of the order of 50 millimeters.
- Installation 1 for winding and unwinding the cable metal 2 comprises a reel 3 and a vertical axis 4 mounted on a support 5.
- the reel 3 consists of a central hub 6, of six radial spokes 7, starting from the hub 6 and comprising curved extensions 8. These curved extensions 8 delimit, for the metal cable 2, a substantially toroidal housing 9.
- the free ends 8 has curved extensions 8 are fixed to a circle 10 which constitutes the zone of introduction and extraction of the cable 2, respectively during its winding and its unwinding.
- the reel 3 may also include a second circle 11, fixed externally to the curved extensions 8 to reinforce the mechanical strength of said reel 3.
- the vertical axis 4 is fixed to the support 5 by any means appropriate.
- the support 5 is partially a yoke concrete, in which a nut is embedded, the vertical axis 4 can have its threaded lower end so that it can be screwed into the nut in question.
- Axis 4 can also be anchored in the clevis itself of concrete permanently.
- the upper end 4 a of the vertical axis 4 has a diameter which is slightly less than the inside diameter of the hub 6, consisting of a simple cylindrical tube, so that said hub 6 can easily be fitted on this end 4 a .
- the locking in position of the hub 6 relative to the axis 4 must be obtained by a stop, which can for example be a pin 12 passing through the end 4 a , by a diametrical hole and on which the hub 6 rests during the positioning of the reel on the axis 4. It can also be a stop integrated in the axis 4, for example the axis 4 having, to form this stop, a diameter equal to or greater than the outside diameter of the hub 6, with the exception of the end 4 a as indicated above.
- the hub 6 has a length I which is significantly less than the diameter D of the O-ring housing 9; moreover, this hub 6 is arranged symmetrically relative to the equatorial plane GG 'of the toroidal housing 9.
- the reel 3 is placed on the vertical axis 4, the circle 10 being turned upwards. Introducing the first end 2a of the cable inside the housing ring 9 through the inner area 13 of the circle 10. Optionally this end 2a is locked in position by a system 14 in which it can be fitted or s 'clip on.
- the operator just needs to grab the cable, push in the direction of arrow F in Figure 1; the cable 2 is rigid enough to be pressed into the toroidal housing 9 on the largest diameter remaining available therein, the reel 3 rotating freely on the axis 4 due to the forces brought into play during the thrust of cable 2 by the operator. Without special precautions, the turns normally form inside the drum.
- the operator need only place the second end of the latter inside the toroidal housing, even when the said end has a hook.
- the operator places the reel 3 on the vertical axis 4 with the circle 10 facing the support 5. He grabs the second end of cable 2, takes it out of the O-ring housing 9 by passing it through the inner zone 13 of the circle 10 and simply pull this end moving from the length to unroll.
- the cable comes to bear on the vertical axis 4, below the hub 6 and this so that the unwinding speed of cable 2 is not synchronous with the speed of rotation of the reel 3 on its axis 4.
- the latter comes to bear on the support 5, which achieves braking allowing the self-regulation of the course.
- the braking effect is preferably obtained with a vertical axis having a reduced height with respect to the support so that the contact with the support can take place quickly after the extraction of the cable.
- the vertical axis will have a height such as the distance between the support 5 and the equatorial plane G-G 'of the toroidal housing 9 will be around 20cm.
- the reel had a diameter of about 430mm, the toroidal housing 9 a diameter of around 100mm and the hub a length of around 50mm.
- the reel had a diameter of the order of 540mm, the toroidal housing 9 a diameter of on the order of 120 to 130mm and the hub a length on the order of 50mm. It should be noted that variants allowing the winding and the cable unwinds of different lengths can use hubs of the same length, which makes it possible to standardize manufacturing. In these drums, it is possible to accommodate lengths from 20 to 30 meters of cable from 10 to 16mm in diameter. Course all above values are indicative and must be adapted to the diameter and the length of the cable.
- these are the extensions curved with six radial spokes which form the toroidal housing of the cable.
- the number of six is, according to the applicant, a sufficient number to that the cable cannot come out of its housing.
