Abstract
Description
Support d'antenne
Les antennes des différents réseaux radiophoniques ou téléphoniques, entre autres, sont montées généralement sur des suppor-ts eleves, aménages sur des sites eux-mêmes aussi hauts que possible afin de couvrir des zones les plus étendues possibles, dans la liite, bie b i e n sur, des interférences entre zones.Antenna support
The antennas of the various radio or telephone networks, among others, are generally mounted on high supports, arranged on sites themselves as high as possible in order to cover the widest possible areas, in the liite, of course , interference between zones.
Généralement, les antennes destinées aux reseaux téléphoniques cellulaires sont montées au sommet de pylônes métalliques, de treillis ou tubulaires. Le nombre d'antennes au sommet d'un même pylône est variable mais peut aller parfois jusqu'a 9. Generally, the antennas intended for cellular telephone networks are mounted on top of metal pylons, trellises or tubulars. The number of antennas at the top of the same pylon is variable but can sometimes go up to 9.
Chaque antenne au sommet du pylône doit être orientée dans un plan horizontal et dans un plan vertical de maniere precise, la precision de l'orientation h o r i z o n t a 1 e et de 1 i n c 1 i n a i s o n v e r t i c a l e e t a n t de l'ordre de i 0 , 5 voir moins.Each antenna at the top of the pylon must be oriented in a horizontal plane and in a vertical plane in a precise manner, the precision of the orientation h o r i z o n t a 1 e and from 1 i n c 1 i n a i s o n v e r t i c a l e e t a n t of the order of i 0, 5 see less.
Du f a i t d e c e t t e grande précision requise pour 1' orientation d'une antenne, la fixation de l'antienne s'effectue au moyen de dispositifs permettant d'obtenir l'angle d'azimut et l'angle de site au demi degré près. Due to the high precision required for the orientation of an antenna, the antenna is fixed by means of devices making it possible to obtain the azimuth angle and the site angle to the nearest half degree.
Comme le montrent les figures la 1 c, le moyen connu utilise actuellement e s t d e f i x e r , sur une sorte de plate-forme si tuée en haut du pylône, et répartis sur la périphérie de cellewci, des mats 1 d'une hauteur a peu pres égale a celle de l'antenne, c'est a dire près de trois mètres. L'antenne 2 est retenue sur ces mâts 1 en trois point, un point inférieur au bas du mât, un point supérieur, près du sommet et un point intermédiaire à peu près au milieu. As shown in Figures 1 c, the known means currently uses estdefixer, on a kind of platform if killed at the top of the pylon, and distributed on the periphery of it, masts 1 of a height about equal to that of the antenna, that is to say almost three meters. The antenna 2 is retained on these masts 1 at three points, a lower point at the bottom of the mast, an upper point, near the top and an intermediate point roughly in the middle.
Les points sont matérialisés, côté mât, par un é t r i e r forman-t collier 3 serre sur le mât et dont la p o s i t i o n en rotation (la même p o u r c h a q u e point) par rapport à l'axe du mât, permet de régler l'azimut de l'antenne 2. The points are materialized, on the mast side, by a stirrup forman-t collar 3 clamps on the mast and whose position in rotation (the same for each point) relative to the axis of the mast, allows to adjust the azimuth of the antenna 2.
Chaque collier porte un etrier dont les branches sont dirigees vers l'antenne, qui elle même porte trois étriers correspondants diriges vers le mât. Each collar carries a stirrup, the branches of which are directed towards the antenna, which itself carries three corresponding stirrups directed towards the mast.
Le c ol 1 i e r inférieur p o r t e un axe horizontal sur lequel vient s'articuler l'étrier 4 solidaire de l'extrémité inferieure de l'antenne, ce qui permet à celle-ci de basculer autour de l'axe dans un plan vertical, et autorise le réglage en site. The lower col 1 ier has a horizontal axis on which the stirrup 4 is articulated secured to the lower end of the antenna, which allows the latter to tilt around the axis in a vertical plane, and authorizes the adjustment in site.
Les colliers moyen et supérieur, sont egalement pourvus d'un axe horizontal sur lequel s'articule 1' extrémité des branches 6 de deux compas 7. The middle and upper collars are also provided with a horizontal axis on which the end of the arms 6 of two compasses 7 is articulated.
L'extrémité 1 ibre des autres branches 6 est articulez sur l'strier 4 solidaire de l'antenne. The end 1 ibre of the other branches 6 is articulated on the bracket 4 secured to the antenna.
Les trois colliers 3 sont montés sur le mât 1 et l'antenne 2 est fixee approximativement par rapport au mât au moyen de l'axe inférieur et des compas 7 articules sur elle et sur les deux colliers 3 moyen et supérieur. Le mâ-t est alors mis s en place au sommet du pylône, en tenant compte de l'orientation p r é c i se à donner en azimu-t. Puis, les compas 7 des colliers moyen et supérieur sont regles pour obtenir l'orientation precise en site. L'opération est recommencee autant de fois qu'il y a d'antennes. The three collars 3 are mounted on the mast 1 and the antenna 2 is fixed approximately relative to the mast by means of the lower axis and compasses 7 articulated on it and on the two collars 3 middle and upper. The mast is then placed at the top of the pylon, taking into account the orientation to be given in azimu-t. Then, the compasses 7 of the middle and upper collars are adjusted to obtain the precise orientation in site. The operation is repeated as many times as there are antennas.
Comme on le voit sur la figure, cela représente au total un minimurn de 24 boulons à serrer par antenne. As seen in the figure, this represents a total of 24 bolts to be tightened by antenna.
De plus le personnel chargé de l'installation e t / o u de la maintenance doit travailler non seulement au sommet d'un pylône d e 40 iii o u plus, mais encore, pour effectuer les reglages d'angle, s'elever d'environ 2 à 3 m, au moyen d'une échelle ou d'un escabeau dispose sur 1 a p 1 a t e - f o r in e à la hauteur du compas supérieur pour en serrer et desserrer les boulons, et ce autant de fois qu'il y a d'antennes, c'est 3 dire jusqu'à 6 ou 9. Tout ceci est incommode et prend du temps tout en etant de plus inconfortable et dangereux pour ledit personnel qui a d é j à gravi une echelle de 40 m ni pour atteindre le sommet du pylône. In addition, the personnel responsible for installation and / or maintenance must work not only at the top of a pylon of 40 iii or more, but also, to make the angle adjustments, rise from approximately 2 to 3 m, by means of a ladder or a stepladder placed on 1 ap 1 ate - for in e at the height of the upper compass to tighten and loosen the bolts, and this as many times as there are antennas, that is to say up to 6 or 9. All this is inconvenient and time consuming while being more uncomfortable and dangerous for the said personnel who have already climbed a 40 m ladder or to reach the top of the pylon.
L' invention permet essentiellement de résoudre deux problèmes : elle permet de réduire la perte de temps pour le réglage des a Ilgles de chaque antenne, decoulant du nombre important de boulons à serrer et de la difficulté du réglage lui-même avec des compas, aggravée encore par le fait qu'il faut monter et descendre plusieurs fois sur l'échelle ou analogue
le confort e t a sécurité de la personne chargee du montage ou du réglage sont améliorés du fait qu'elle peut travailler sur chaque antenne depuis la plate-forme du somniet du pylône, sans avoir à s'elever au-dessus de cette plate-forme par un quelconque moyen.The invention essentially solves two problems: it reduces the loss of time for adjusting the angles of each antenna, resulting from the large number of bolts to be tightened and the difficulty of the adjustment itself with compasses, aggravated again by the fact that you have to go up and down several times on the ladder or the like
the comfort and safety of the person responsible for mounting or adjusting are improved by the fact that he can work on each antenna from the platform of the pylon somniet, without having to rise above this platform by any means.
Ces buts sont atteint selon l'invention pour un dispositif de r xation et de réglage angulaire d'antenne de transmissions hertziennes sur une construc-tion prévue pour porter plusieurs de ces antennes, en ce que le dispositif comporte deux attaches parallèles, articulées à proximité l'une de 1' autre par une extremité à la base d'un support rigide, approximativement de même longueur que l'antenne et solidarisé à celle-ci de façon à lui communiquer sa rigidité, et fixées de l'autre côte à u n mât vertical, monte sur ladite construction, de manière à f o r n e r avec 1 e in à t et la partie du siipport comprise entre le deux attaches un quadrilatère déformable dans le plan vertical, permettant de régler l'inclinaison de l'antenne en agissant sur les attaches directement accessibles depuis le sommet de la construction. These aims are achieved according to the invention for a device for r xation and angular adjustment of antenna of hertzian transmissions on a construc-tion intended to carry several of these antennas, in that the device comprises two parallel fasteners, articulated close one from the other by an end at the base of a rigid support, approximately the same length as the antenna and secured to it so as to communicate its rigidity, and fixed on the other side to a vertical mast, mounts on said construction, so as to form with 1 e in at t and the part of the siipport between the two fasteners a deformable quadrilateral in the vertical plane, making it possible to adjust the inclination of the antenna by acting on the fasteners directly accessible from the top of the construction.
Selon l'invention, la première attache est constituée d'un côte par un premier collier destine à fixer l'ensemble sur un mât vertical fixe et de l'autre côte par un premier etrier en forme de fourche dont 1 'e x t r é ni i t é 1 i b r e des b r a n c h e s s' a r t i c u 1 e sur 1 e support pour former un point de p i v o t e m e n t de l'antenne. According to the invention, the first attachment consists of one side by a first collar intended to fix the assembly on a fixed vertical mast and on the other side by a first fork-shaped stirrup, the end of which é 1 ibre des branchesess' articu 1 e on 1 e support to form a pivot point of the antenna.
La seconde attache est constituée d'un second étrier a r t i c u 1 é d'une c ô t é sur 1 e s u p p o r t d' a n t e n n e près de sa b a s e e t d o n t 1 e s branches situees du côte oppose à l'articulation, embrassent un second collier destine à être serré autour du mât vertical, et qui présente des moyens diamétralemerl-t opposés d' articulation desdites branches pourvues à cet effet de trous allongés, les trous allongés permettant un reglage de l'angle d'inclinaison de l'antenne par rapport à la verticale e n faisant varier la position du point d'attache du second étrier sur le second collier, ce qui a pour effet de f a i r e pivoter 1 'a n t e n n e autour de l'articulation sur la première attache. The second attachment consists of a second articulated bracket 1 on one side on the antenna support near its base and of which the branches located on the side opposite the joint, embrace a second collar intended to be tightened around vertical mast, and which has diametralemerl-t opposite means of articulation of said branches provided for this purpose with elongated holes, the elongated holes allowing adjustment of the angle of inclination of the antenna relative to the vertical by making vary the position of the attachment point of the second bracket on the second collar, which has the effect of rotating the antenna around the joint on the first attachment.
Selon l'invention, le support est constitué d'un profilé rigide dont l'épaisseur3 dans le plan de l'antenne, est collStante entre les deux points de fixation sur le mât et va en décroissant depuis chacun de ces points vers l'extrémité respective du support. According to the invention, the support consists of a rigid profile whose thickness3 in the plane of the antenna, is sticky between the two fixing points on the mast and decreases from each of these points towards the end respective support.
Selon une caractéristique de l'invention, le point de 1 i a i s o n de 1 a p r e n i è r e a t t a c h e au support constituant le point de pivotement de l'antenne est situé a p p r o x i m a t i v e m e n t au t i e r s de 1 a 1 o n g u e u r du support à partir du bas. According to a characteristic of the invention, the point of 1 i a i s o n of 1 a p r e n i è r e a t t a c h e to the support constituting the pivot point of the antenna is located p p r o x i m a t i v e m e n t au t i e r s from 1 to 1 o n g u e u r of the support from the bottom.
D'autre part, le point de liaison de la seconde attache au support auquel est transmis la translation horizontale des branches du second étrier par rapport au second collier est situe à environ un sixième de la longueur du support à partir du bas. On the other hand, the point of connection of the second attachment to the support to which the horizontal translation of the branches of the second stirrup relative to the second collar is transmitted is located about one sixth of the length of the support from the bottom.

Commue on le voit sur la figure 2, l'antenne 3 est montee sur un support 2 de longueur equivalente qui la rigidifie et permet son montage et son reglage angulaire. L'antenne selon 1' exe rn ple de réalisation ni e s u r e e n v i r o n 3 m et est fixée v e r t i c al e m e n t sur un mât 1 d'environ 1,20 m au moyen de deux attaches 4 et 5 dont l'une 4 est reliez au support 2 à environ un tiers de la hauteur de celui-ci en partant du bas, et l'autre 5 à peu pres à mi-chemin entre le bas du support et l'attache 4. As seen in Figure 2, the antenna 3 is mounted on a support 2 of equivalent length which stiffens it and allows its mounting and its angular adjustment. The antenna according to the exemplary embodiment or measure approximately 3 m and is fixed vertically to a mast 1 of about 1.20 m by means of two fasteners 4 and 5, one of which 4 is connected to the support 2 about a third of the height of it from the bottom, and the other 5 about halfway between the bottom of the support and the fastener 4.
Comme le montre la figure 3, l'attache 4 cons-titue un point de pivotement dans le plan vertical de 1' antenne par rapport au mât. Elle comprend un collier 6 pouvant être serré autour du mât 1 et supportant u n é t r i e r e n forme de fourche dont les branches 7 sont articulées en 8, grâce à un boulon, à leur extrémite sur le support 2 de l'antenne 3. As shown in Figure 3, the fastener 4 constitutes a pivot point in the vertical plane of the antenna relative to the mast. It comprises a collar 6 which can be tightened around the mast 1 and supporting a fork in the form of a fork, the branches 7 of which are articulated at 8, by means of a bolt, at their extremity on the support 2 of the antenna 3.
L'attache 5 est représentée sur la figure 4. The fastener 5 is shown in FIG. 4.
Elle comprend un collier 8 pouvant être serré autour du mât 1 et un étrier 10 fixe de manière articulée en 11 au support d'antenne 2. Les branches de l'étrier 10 sont pourvues de trous oblongs 12 permettant de serrer lesdites branches sur le collier 10, au moyen de boulons, en réglant la distance entre le point d'articulation 11 sur le support 2 et le point d'attache 13 de l'étrier 10 sur le collier 9. It comprises a collar 8 which can be tightened around the mast 1 and a stirrup 10 fixed in an articulated manner at 11 to the antenna support 2. The branches of the stirrup 10 are provided with oblong holes 12 making it possible to tighten said branches on the collar 10, by means of bolts, by adjusting the distance between the articulation point 11 on the support 2 and the attachment point 13 of the stirrup 10 on the collar 9.
Le montage de l'antenne sur le mât 1 s'effectue simplement depuis 1 a plate-forme au sommet du pylône par serrage des colliers 6 et 9 sur le mât 1 de façon que 1 ' a n t e n n e 3 s o i t c o r r e c t e m e n t d i r i g é e en a z i m u t. The mounting of the antenna on the mast 1 is carried out simply from 1 to the platform at the top of the pylon by tightening the collars 6 and 9 on the mast 1 so that 1 'a nt e n ne 3 s o i t c o r r e c t e m e n t d i r i g é e en a z i m u t.
Puis, par coulissement des branches de l'étrier 10 de l'attache 5 par rapport au collier 9, l'angle de site est ajusté en ce que le support 2 repousse du ou tire vers le vinât 1 par le point 11, pivote autour du boulon 8 servant de point de pivotement sur l'attache 4. Then, by sliding the branches of the stirrup 10 of the fastener 5 relative to the collar 9, the elevation angle is adjusted in that the support 2 pushes back or pulls towards the wine 1 by the point 11, pivots around bolt 8 serving as a pivot point on fastener 4.
Ainsi, le montage et le réglage d'un antenne sont réalises rapidement, sans difficulte pour fixer la position déterminée et surtout sans avoir à s'élever encore au-dessus du sommet du pylône. Thus, the mounting and adjustment of an antenna are carried out quickly, without difficulty in fixing the determined position and above all without having to rise further above the top of the pylon.
