Description

Description Description

[0001] La presente invention a pour objet un dispositif d'entrainement pour pousser ou tirer un fil sans abimer sa surface peripherique, comportant un boTtier dans lequel est disposee une poulie entrainee par un moteur. Ce genre de dispositif est generalement utilise pour introduire des fils ou des fibres optiques dans des canalisations. The present invention relates to a drive device for pushing or pulling a wire without damaging its peripheral surface, comprising a casing in which is arranged a pulley driven by a motor. This type of device is generally used to introduce wires or optical fibers into pipes.

[0002] Le probleme d'introduire notamment des cäbles electriques dans des conduits ou gaines est connu depuis longtemps. On trouvera des exposes de ce dernier probleme par exemple dans les demandes de brevet publiee WO 2010/ 111801 et FR 82537795. [0002] The problem of introducing electric cables in particular into conduits or ducts has been known for a long time. Descriptions of this latter problem can be found, for example, in published patent applications WO 2010/111801 and FR 82537795.

[0003] Actuellement ce probleme a ete resolu notamment par des dispositifs comme ceux exposes, par exemple, dans les publications US 2556484 (publiee le 12.06.1951), US 6722603 (publiee le 20.04.2004) et US 4413808 (publiee le 08.11.1983). Tous ces dispositifs connus definissent des dispositifs comportant un boTtier dans lequel est enroule une longueur de fil destine ä etre introduit et ressortit d'un tube. Ainsi, ils pourront etre utilises dans des installations qui presentent des tubes qui ont une longueur, qui doit etre inferieure ä la longueur du fil contenu dans les dispositifs. Pour utiliser ces dispositifs dans des installations qui ont des longueurs de tube plus grandes il faudra changer la reserve de fil dans lesdits dispositifs, ce qui apportera des complications techniques. De plus, ces dispositifs sont compliques et relativement chers. Currently this problem has been solved in particular by devices such as those exposed, for example, in the publications US 2556484 (published on 06.12.1951), US 6722603 (published on 04.20.2004) and US 4413808 (published on 08.11. 1983). All these known devices define devices comprising a casing in which is wound a length of wire intended to be introduced into and emerges from a tube. Thus, they can be used in installations which have tubes which have a length which must be less than the length of the wire contained in the devices. To use these devices in installations which have longer tube lengths it will be necessary to change the reserve of wire in the said devices, which will bring about technical complications. In addition, these devices are complicated and relatively expensive.

[0004] On connait aussi des dispositifs qui n'ont pas les defauts des dispositifs decrits ci-dessus, par exemple dans lebrevet FR 1.586.534 (publie le 20.02.1970), il est decrit un dispositif qui se presente sous forme d'un pistolet et qui peut pousser ou tirer un fil d'acier dans un tube. Le fil d'acier est pousse ou tire en etant serre elastiquement entre deux paires de disques. Ce dispositif ne etre utilise qu'avec un fil d'acier, car il faut une forte pression pour le deplacer. Ce dispositif ne peut pas etre utilise avec des fils en matiere synthetique encore moins avec des fibres optiques. [0004] Devices are also known which do not have the defects of the devices described above, for example in patent FR 1,586,534 (published on 02.20.1970), a device is described which is in the form of a a gun and can push or pull a steel wire through a tube. The steel wire is pushed or pulled by being clamped elastically between two pairs of discs. This device can only be used with a steel wire, because it requires strong pressure to move it. This device cannot be used with synthetic material threads, even less with optical fibres.

[0005] Un autre dispositif est decrit dans le brevet ES 2561703 (publie le 04.02.2016). Ce dernier dispositif fonctionne de la meme maniere que celui decrit dans le brevet franqais, donc il sera inutilisable avec des fils synthetiques ou des fibres optiques. Another device is described in patent ES 2561703 (published on 04.02.2016). This last device works in the same way as that described in the French patent, so it will be unusable with synthetic threads or optical fibers.

[0006] L'invention a pour buts de fournir un dispositif d'entrainement pour pousser ou tirer un fil sans abimer sa surface, qui n'a pas les defauts des dispositifs connus, c'est-ä-dire qui ne comporte pas de reserve de fil et qui puisse etre utilise avecdes fils synthetiques ou des fibres optiques, et de plus qui soit leger, comportant peu de pieces, donc facile ä fabriquer, donc bon marche. [0006] The aim of the invention is to provide a drive device for pushing or pulling a wire without damaging its surface, which does not have the defects of known devices, that is to say which does not comprise yarn reserve and which can be used with synthetic yarns or optical fibres, and moreover which is light, comprising few parts, therefore easy to manufacture, therefore inexpensive.

[0007] Ces buts sont atteints avec le dispositif d'entrainement pour pousser ou tirer un fil sans abimer sa surface peripherique selon l'invention definie ä la revendication 1. [0007] These objects are achieved with the drive device for pushing or pulling a wire without damaging its peripheral surface according to the invention defined in claim 1.

Claims (8)

[0010] Le dispositif montre ä la figure 1 represente une forme d'execution du dispositif revendique ä la revendication 1. Ce dispositif comporte un boitier dont on a represente que le fond 1 comportant une ouverture 29. Sur ce fond 1 sont disposes cote anterieur, qui represente la partie disposee ä l'interieur dudit boitier, une couronne 5 presentant ä sa circonference une rainure 18, voir figure 6B, en forme de U ä fond plat dont l'ouverture est dirigee vers l'exterieur de la dite couronne maintenue en place par des cales de guidage 7a et 7b, et une poulie 4 tournant autour de Taxe 13, et des tubes 9 et 10. La poulie 4 est maintenue en rotation par le moteur 2 au moyen d'un groupe reducteur 12 dispose sur le cöte posterieur oppose au cöte anterieur. Le groupe reducteur 12 entraine Taxe 13 qui est fixe ä la poulie 4. [0010] The device shown in FIG. 1 represents an embodiment of the device claimed in claim 1. This device comprises a casing of which it has been shown that the bottom 1 comprising an opening 29. On this bottom 1 are arranged on the front side , which represents the part arranged inside said case, a crown 5 having on its circumference a groove 18, see FIG. 6B, in the shape of a U with a flat bottom, the opening of which is directed towards the outside of said crown in place by guide blocks 7a and 7b, and a pulley 4 rotating around shaft 13, and tubes 9 and 10. Pulley 4 is kept in rotation by motor 2 by means of a reduction unit 12 placed on the posterior side opposite the anterior side. Reduction unit 12 drives shaft 13 which is fixed to pulley 4. [0011] La poulie 4 peutavoir une surface lisse ou moletee, maiselle peut aussi avoir une rainure dans laquelle est introduite la courroie 3. La courroie 3 est introduite dans la rainure 18 de la couronne 5, voir figure 6B. La courroie 3 entrainee par la poulie 4 entraine en rotation la couronne 5. De plus la courroie 3 recouvre les spires de fil 11 (fig 6B) disposees dans la rainure 18 en les comprimant sur le fond de la dite rainure. Pour que la courroie 3 assure une bonne rotation de la couronne 5 il est prevu des moyens de tension de ladite courroie, ces moyens de tension sont par exemple constitues par un galet 6 dispose libre en rotation sur Taxe 14 et s'appuyant par sa surface peripherique sur la surface interieure de la couronne 5. Le galet 6 peut se deplacer sensiblement radialement relativement ä la couronne 5. En effet, voir figure 2, le galet 6 est monte sur un axe 14 fixe sur un levier 19, ce levier 19 est dispose articule sur un axe 15. Le levier 19 est tire par un ressort 20 au moyen de Taxe 22 et ledit ressort est fixe sur le cöte posterieur du fond 1 au moyen d'un axe 21. Le ressort 20 peut comprendre des moyens de reglage de sa tension, ces moyens ne sont pas representes car ils sont ä la portee de l'homme du metier. De plus la courroie 3 pourrait etre tendue par un dispositif comportant un levier maintenu par un ressort, ces moyens de tension ne sont pas representes car ils sont ä la portee de l'homme de metier. The pulley 4 can have a smooth or knurled surface, but it can also have a groove into which the belt 3 is inserted. The belt 3 is inserted into the groove 18 of the crown 5, see FIG. 6B. The belt 3 driven by the pulley 4 rotates the crown 5. In addition the belt 3 covers the turns of wire 11 (fig 6B) arranged in the groove 18 by compressing them on the bottom of said groove. For the belt 3 to ensure proper rotation of the crown 5, means for tensioning said belt are provided, these tensioning means are for example constituted by a roller 6 arranged freely in rotation on the axis 14 and resting by its surface peripheral on the inner surface of crown 5. Roller 6 can move substantially radially relative to crown 5. Indeed, see FIG. 2, roller 6 is mounted on a shaft 14 fixed on a lever 19, this lever has articulated on an axis 15. The lever 19 is pulled by a spring 20 by means of tax 22 and said spring is fixed on the rear side of the bottom 1 by means of an axis 21. The spring 20 can comprise adjustment means of its voltage, these means are not represented because they are within the reach of a person skilled in the art. In addition, the belt 3 could be tensioned by a device comprising a lever held by a spring, these tensioning means are not shown because they are within the reach of a skilled person. [0012] Sur la figure 3 le dispositif represente ä la figure 1 est Charge d'un fil 11, comportant ä son extremite une sonde 23, pret ä etre introduit dans un tube 25 dispose dans une boite 24 disposee dans un mur. Pour charger un fil dans le dispositif, il faut introduire le fil 11 dans le tube 10 fixe sur le fond 1 par la cale 16 et le pousser ä l'interieur de maniere qu'il passe entre la cale de guidage 8 et la couronne 5 dans la rainure 18 (voir figure 6B). Le fil 11 poursuivra son chemin dans la rainure 18 maintenu au fond de cette derniere par la courroie 3. Ensuite le fil 11 fera un tour de la couronne 5 dans la gorge 18 et repassera sous la cale de guidage 8. La cale 8 a une largeur legerement interieure ä la distance separant les deux montants dudit U de maniere qu'elle puisse etre maintenue entre ces derniers en maintenant le fil 11 contre la couronne 5 augmentant son frottement sur cette derniere. Suivant le diametre du fil 11 et la largeur de la rainure 18, le fil 11 fera plus d'un tour sur la couronne 5, puis il sortira par le tube 9 fixe sur le fond 1 par la calet 7 et s'introduira dans le tube 25 par la sonde 23. [0012] In FIG. 3, the device represented in FIG. 1 is loaded with a wire 11, comprising at its end a probe 23, ready to be introduced into a tube 25 placed in a box 24 placed in a wall. To load a thread into the device, it is necessary to introduce the thread 11 into the tube 10 fixed on the bottom 1 by the wedge 16 and push it inside so that it passes between the guide wedge 8 and the crown 5 in the groove 18 (see Figure 6B). The wire 11 will continue its way in the groove 18 held at the bottom of the latter by the belt 3. Then the wire 11 will go around the crown 5 in the groove 18 and will pass under the guide wedge 8. The wedge 8 has a width slightly inside the distance separating the two uprights of said U so that it can be held between them by holding the wire 11 against the crown 5 increasing its friction on the latter. Depending on the diameter of the wire 11 and the width of the groove 18, the wire 11 will make more than one turn on the crown 5, then it will come out through the tube 9 fixed on the bottom 1 by the wedge 7 and will be introduced into the tube 25 by probe 23. [0013] Dans une autre forme d'execution (voir figure 7). II est prevu de supprimer le galet 6, la tension de la courroie 3 etant realisee par la cale de guidage 8 montee sur des moyens elastiques et pouvant se deplacer contre la couronne 5. Les moyens elastiques assurant le deplacement de la cale 8 sont semblables ä ceux decrits pour le galet 6 ä la figure 2. La cale 8 a une largeur legerement interieure ä la distance separant les deux montants dudit U de maniere qu'elle puisse etre maintenue entre ces derniers en maintenant le fil 11 contre la couronne 5 augmentant son frottement sur cette derniere. La cale 8 presente des galets 28 s'appuyant contre le fil 11 pour faciliter le deplacement du fil 11. Les galets 28 sont montes sur des axes 26 dans la cale 8 (voir figure 7 et 8) et cette cale est fixee ä Taxe 27, qui est fixe ä un levier identique au levier 19, non represente. Ainsi la cale 8 poussera la couronne 5 l'eloignant de la poulie 4 et tendra la courroie 3. In another form of execution (see Figure 7). It is planned to remove the roller 6, the tension of the belt 3 being carried out by the guide wedge 8 mounted on elastic means and able to move against the crown 5. The elastic means ensuring the displacement of the wedge 8 are similar to those described for the roller 6 in FIG. 2. The wedge 8 has a width slightly inside the distance separating the two uprights of said U so that it can be held between the latter by holding the wire 11 against the crown 5 increasing its friction on the latter. Wedge 8 has rollers 28 bearing against wire 11 to facilitate movement of wire 11. Rollers 28 are mounted on pins 26 in wedge 8 (see Figures 7 and 8) and this wedge is fixed to rod 27 , which is attached to a lever identical to lever 19, not shown. Thus wedge 8 will push crown 5 away from pulley 4 and tension belt 3. [0014] Dans une troisieme forme d'execution representee ä la figure 9, avec un detail represente ä la figure 12. La forme d'execution est proche de celle representee ä la figure 7, la difference principale etant que l'entrainement de couronne 5 est assure par une chaine 29. Comme on le voit ä la figure 12 c'est la chaine 29, qui assure le maintien sous pression du fil 11 dans la rainure en V 31 prevue dans le fond 18. In a third embodiment shown in Figure 9, with a detail shown in Figure 12. The embodiment is close to that shown in Figure 7, the main difference being that the crown drive 5 is ensured by a chain 29. As can be seen in FIG. 12, it is the chain 29 which ensures that the wire 11 is held under pressure in the V-groove 31 provided in the bottom 18. [0015] Dans une Variante de la forme d'execution representee ä la figure 9, avec un detail represente ä la figure 10, la chaine est remplacee par une courroie crantee 3 comme dans la forme d'execution representee ä la figure 1. Comme on le voit ä la figure 10 c'est la courroie 3, qui assure le maintien sous pression du fil 11 dans la rainure 31 prevue dans le fond 18. In a variant of the embodiment shown in Figure 9, with a detail shown in Figure 10, the chain is replaced by a toothed belt 3 as in the embodiment shown in Figure 1. As as can be seen in figure 10, it is the belt 3 which maintains the wire 11 under pressure in the groove 31 provided in the bottom 18. [0016] Dans une derniere Variante de la forme d'execution representee ä la figure 9, avec un detail represente ä la figure 11, la chaine est remplacee par une courroie de section circulaire 30 est le fond du U n'est plus plat mais ä la forme d'un V. Comme on le voit ä la figure 10 c'est la courroie 30, qui assure le maintien sous pression du fil 11 dans le fond du V. In a final variant of the embodiment shown in Figure 9, with a detail shown in Figure 11, the chain is replaced by a belt of circular section 30 is the bottom of the U is no longer flat but in the shape of a V. As can be seen in FIG. 10, it is the belt 30 which ensures the maintenance under pressure of the wire 11 in the bottom of the V. [0017] L'invention permet d'obtenir un dispositif d'entrainement pour pousser ou tirer un fil sans abimer sa surface peripherique, presentant une grande force de poussee ou de traction, car la force de frottement sur la couronne est assuree par la pression de la courroie sur le fil 11. [0017] The invention makes it possible to obtain a drive device for pushing or pulling a wire without damaging its peripheral surface, having a great pushing or pulling force, because the friction force on the crown is ensured by the pressure of the belt on wire 11.
