Abstract
Description
La présente invention a pour objet un dispositif amortisseur à limite de surcharge pour support de câble aérien. The present invention relates to an overload limit device for an overhead cable support.
Elle se rapporte d'une manière générale au domaine industriel des accessoires pour câbles aériens isolés, qu'ils soient électriques ou téléphoniques. En dehors des agglomérations, la distribution d'énergie électrique ainsi que les liaisons téléphoniques sont, encore réalisées pour une part importante par des câbles aériens. Le système de maintien d'un câble électrique ou téléphonique fait généralement appel à un montage mécanique par fixation rigide du câble 1 sur le poteau, ou au moyen d'une balancelle 2 suspendue au poteau l'intermédiaire d'un support constitué d'une chape 3 montée sur un anneau 4 disposé à l'extrémité d'une tige 5 solidaire d'une platine fi fixée sur le poteau (cf figure 1). systèmes à un ou deux degrés de liberté ne laissent que peu de possibilités d'absorption des contraintes mécaniques, qui provoque, lors d'intempéries importantes telles que tempêtes, cyclones, ouragans ou dépôt de givre important, une surcharge pouvant amener la rupture du systeme d'accrochage ou du câble, voire de l'ensemble câble-poteau. It relates generally to the industrial field of accessories for insulated overhead cables, whether electrical or telephone. Outside urban areas, the distribution of electrical energy as well as the telephone links are still made for a large part by overhead cables. The system for holding an electrical or telephone cable generally uses a mechanical mounting by rigidly attaching the cable 1 to the post, or by means of a swing 2 suspended to the post via a support consisting of a clevis 3 mounted on a ring 4 disposed at the end of a rod 5 secured to a plate fi fixed to the pole (see Figure 1). systems with one or two degrees of freedom leave little possibility of absorption of mechanical stresses, which causes, in severe weather such as storms, cyclones, hurricanes or significant frost deposit, an overload that could bring about the rupture of the system. hooking or cable, or even the cable-pole assembly.
dispositif selon l'invention a pour but de réaliser une combinaison d'éléments intégrables entre la chape et la balancelle, et permettant la suspension de câbles aériens en absorbant dans les trois axes les contraintes mécaniques dues aux intempéries, le système amortissant dans le sens vertical les effets courants dus au vent et à la pluie et libérant l'accrochage au-dessus d'un seuil déterminé de contraintes, ce qui évite la destruction du câble et du poteau et de son armement. device according to the invention aims to achieve a combination of integrable elements between the yoke and the swing, and allowing the suspension of overhead cables by absorbing in the three axes the mechanical stresses due to bad weather, the system damping in the vertical direction the current effects due to the wind and the rain and freeing the hanging above a determined threshold of constraints, which avoids the destruction of the cable and the post and its armament.
II est constitué d'un système amortisseur s'insérant entre la balancelle et la chape du support de fixation des câbles et comportant deux demi-crochets maintenant au repos la balancelle portant le câble aérien, tige, solidaire du support fixé au poteau permettant de déverrouiller les demi-crochets et de libérer le câble lorsque l'effort subi par le câble dépasse un seuil détermine et produit sur cette tige une traction suffisante pour comprimer un ressort taré maintenant le système verrouillé au repos. It consists of a damping system inserted between the swing and the yoke of the cable fixing bracket and having two half-hooks now at rest the swing carrying the aerial cable, rod, secured to the support fixed to the pole to unlock the half-hooks and release the cable when the force incurred by the cable exceeds a threshold determines and produces on this rod sufficient traction to compress a calibrated spring maintaining the locked system at rest.
Sur les dessins annexés, donnés à titre d'exemple non limitatif d'une des formes de réalisation de l'objet de l'invention figure 1, déjà mentionnée, représente en perspective cavalière un ensemble d'accrochage de câble à balancelle équipé du dispositif revendique, figures 2 et 3 montrent, à une échelle différente, le dispositif selon l'invention vu respectivement de face et de côté. In the accompanying drawings, given by way of non-limiting example of one of the embodiments of the object of the invention, FIG. 1, already mentioned, represents in a cavalier perspective a swinging cable attachment assembly equipped with the device claims, Figures 2 and 3 show, on a different scale, the device according to the invention seen respectively front and side.
et figures 4 à 6 sont des coupes agrandies, suivant les flèches F1 de la figure 3, représentant successivement le dispositif au repos, en extension sans ouverture, et en position d'ouverture. and FIGS. 4 to 6 are enlarged sections, along the arrows F1 of FIG. 3, successively representing the device at rest, in extension without opening, and in the open position.
Le dispositif, figures 1 à 6, est constitué d'une cloche 7 contenant deux demi-crochets 8, 9 articulés, agencés pour constituer au repos une chape pouvant porter la balancelle 2. L'ensemble est solidarisé avec la chape 3 du support de câble par une embase 10 comportant un axe 11. Une tige 12 solidaire de l'embase 8 est guidée dans une cavité cylindrique 13 formée par les deux demi-crochets 8, 9. Ces derniers peuvent s'ouvrir autour de leur axe 14 en libérant la balancelle supportant le câble Un premier ressort 15, prenant appui sur une plaque circulaire 16 fixée à l'extrémité inférieure de la tige 12 coulissant dans la cavité 13, donne câble 1 une certaine liberté de mouvement dans le sens vertical en fonction des sollicitations mécaniques extérieures, ce qui confère au dispositif un effet amortisseur des contraintes (figure 5). The device, Figures 1 to 6, consists of a bell 7 containing two half-hooks 8, 9 articulated, arranged to form at rest a clevis can carry the swing 2. The assembly is secured with the yoke 3 of the support of cable by a base 10 having an axis 11. A rod 12 integral with the base 8 is guided in a cylindrical cavity 13 formed by the two half-hooks 8, 9. These can open around their axis 14 by releasing the swing supporting the cable A first spring 15, resting on a circular plate 16 fixed to the lower end of the rod 12 sliding in the cavity 13, gives cable 1 a certain freedom of movement in the vertical direction depending on the mechanical stresses external, which gives the device a damping effect of constraints (Figure 5).
Un second ressort 17, taré, assure le verrouillage des deux demi- crochets 9 en appuyant sur une plaque percée 18 mobile, placée dessous de la plaque circulaire 16 et sur les bords de laquelle viennent buter épaulements prévus sur la partie supérieure des deux demi-crochets. Lorsque l'effort dépasse un seuil déterminé, la plaque mobile 18 se soulève, entraînée par la tige 12 par l'intermédiaire de la plaque circulaire 16, et les deux demi-crochets peuvent basculer, ce qui provoque leur ouverture et la libération de la balancelle 2 et du câble 1 en rendant impossible le retour à la position initiale (figure 6). A second spring 17, calibrated, ensures the locking of the two half-hooks 9 by pressing a pierced plate 18 movable, placed below the circular plate 16 and on the edges of which abut shoulders provided on the upper part of the two half hooks. When the force exceeds a determined threshold, the movable plate 18 rises, driven by the rod 12 through the circular plate 16, and the two half-hooks can tilt, causing their opening and release of the Swing 2 and cable 1 making it impossible to return to the initial position (Figure 6).
Le système peut être réarmé en tirant sur la tige 12 pour soulever la plaque percée 18, ce qui permet de refermer les deux demi-crochets 8, 9 en emprisonnant l'axe de la balancelle 2. La tige 12 est alors relâchée de façon à ce que la plaque circulaire 16 retrouve sa position dans la cavité circulaire 13 (figure 4). The system can be rearmed by pulling on the rod 12 to lift the pierced plate 18, which allows to close the two half-hooks 8, 9 by trapping the axis of the swing 2. The rod 12 is then released so as to that the circular plate 16 finds its position in the circular cavity 13 (Figure 4).
Le tarage du ressort 17 permet de déterminer le seuil de libération du câble . II est en particulier possible d'empêcher la libération du câble dans certains cas particuliers tels que passage de route, par exemple. The calibration of the spring 17 makes it possible to determine the release threshold of the cable. In particular it is possible to prevent the release of the cable in particular cases such as road crossing, for example.
Selon une première variante d'exécution, le dispositif comporte deux ressorts de tarage 17 répartis sur la plaque percée 18. According to a first variant embodiment, the device comprises two setting springs 17 distributed on the pierced plate 18.
Selon une seconde variante d'exécution, le dispositif peut être équipe d'un amortisseur hydraulique. According to a second variant embodiment, the device can be equipped with a hydraulic damper.
L'invention ne se limite pas à la seule forme d'exécution du dispositif qui a eté décrite ci-dessus à titre d'exemple; elle en embrasse au contraire toutes les variantes de réalisation et d'application respectant les mêmes principes et peut être adaptée à tout système physique pour amortissement de contraintes et pour limitation de surcharge. The invention is not limited to the sole embodiment of the device which has been described above by way of example; on the contrary, it embraces all variants of implementation and application respecting the same principles and can be adapted to any physical system for stress damping and for overload limitation.
Le positionnement des divers éléments constitutifs donne à l'objet l'invention un maximum d'effets utiles qui n'avaient pas été, à ce jour, obtenus par des dispositifs similaires.The positioning of the various constituent elements gives the object of the invention a maximum of useful effects that had not been obtained so far by similar devices.
