La présente invention concerne un système de chariots-profilés destiné àThe present invention relates to a profile carriage system for
équiper les installationsequip the facilities
diverses d'éclairage ou de télésurveillance. various lighting or remote monitoring.
Il est en effet souvent nécessaire d'éclairer de façon intensive certaines surfaces extérieures, voies de circulation, places, stades, aérodromes, etc.. Cela impose d'établir à de grandes hauteurs, pouvant 5 dépasser 20 mètres, des systèmes d'éclairage puissants, en particulier lorsqu'ils doivent servir à des transmissions télévisées, donc souvent très pesants. De même les nécessités de la télésurveillance imposent l'existence de caméras ou autres équipements en hauteur. Dans tous ces cas, les appareillages doivent tre fréquemment entretenus, ce qui, en général, nécessite qu'ils soient ramenés au sol. Pour y parvenir il faut disposer d'équipements comprenant des systèmes de traction munis de 10 tous les dispositifs de sécurité nécessaires, en particulier de freins assurant la protection du personnel It is indeed often necessary to intensively light certain exterior surfaces, traffic lanes, squares, stadiums, aerodromes, etc. This requires lighting systems to be installed at great heights, which may exceed 20 meters. powerful, especially when used for television transmissions, so often very heavy. Likewise, the needs of remote monitoring require the existence of cameras or other equipment at height. In all these cases, the apparatuses must be frequently maintained, which, in general, requires that they be brought back to the ground. To achieve this, it is necessary to have equipment comprising traction systems fitted with all the necessary safety devices, in particular brakes ensuring the protection of personnel.
et du public.and the public.
Diverses solutions ont été proposées à cet effet. Il existe des systèmes penrmettant l'inclinaison du mât, d'autres qui assurent la montée et la descente des équipements à l'aide de dispositifs divers, en particulier comportant des profilés métalliques creux à l'intérieur desquels sont disposés les câbles 15 d'alimentation, mais l'expérience montre qu'il est très difficile, sur une grande longueur d'utiliser les Various solutions have been proposed for this purpose. There are systems permitting the inclination of the mast, others which ensure the raising and lowering of the equipment by means of various devices, in particular comprising hollow metal profiles inside which the cables 15 are arranged. feeding, but experience shows that it is very difficult, over a long length, to use the
parties creuses du profilé..hollow sections of the profile.
L'objet de la présente invention est alors d'établir un nouveau système de dispositif destiné à assurer The object of the present invention is then to establish a new device system intended to ensure
la montée et la descente des équipements. raising and lowering of equipment.
Cette opération implique le guidage et la traction d'un équipement pouvant atteindre une tonne, ainsi 20 que le guidage des commandes électriques courants forts et courants faibles. This operation involves guiding and pulling equipment up to a ton, as well as guiding the high current and low current electrical controls.
A cet effet la présente invention décrit un système de profilé tel que montré dans la figure 1. To this end, the present invention describes a profile system as shown in FIG. 1.
Pour permnnettre la mise en oeuvrre de chariots porte câble de traction ou porte câble électrique, le profilé To allow the implementation of trolleys carrying traction cable or electric cable holder, the profile
comporte deux parties qui peuvent être identiques, telles que 10. has two parts which can be identical, such as 10.
Le profilé comporte des éléments successifs dont chacun d'eux a une longueur variable, par exemple 25 lm50, sont ajustés l'un par rapport à l'autre par des procédés adéquats, par exemple par le double The profile comprises successive elements, each of which has a variable length, for example 25 lm50, are adjusted relative to each other by suitable methods, for example by double
moyen d'une part de goupilles telles que 14 placées dans le logement 6 et qui sont aboutées comme l'indique la figure 4, d'autre part d'éclisses telles que 15 qui sont boulonnées en 16 sur l'un des profilés seulement, de manière à pallier la dilatation et sont placées dans le logement 25. L'élément du profilé est fixé sur le mât support par des boulonnages tels que 7. Ce support peut d'ailleurs être toute 30 autre chose, comme un mur, un soubassement d'ouvrage d'art, un pilier...Le fond du profilé est disposé de manière à pouvoir recevoir le cas échéant l'effort d'un système de freinage. means on the one hand of pins such as 14 placed in the housing 6 and which are abutted as indicated in FIG. 4, on the other hand of splints such as 15 which are bolted at 16 on one of the sections only, so as to compensate for the expansion and are placed in the housing 25. The element of the profile is fixed to the support mast by bolts such as 7. This support can moreover be anything else, such as a wall, a base structure, a pillar ... The bottom of the profile is arranged so that it can receive, if necessary, the force of a braking system.
Les chariots comprennent une partie métallique 2 qui est encastrée à chaque extrémité dans des patins 1 en téflon ou toute autre matière. Ces patins constituent des pièces d'usure qui coulissent dans le logement adéquat du profilé. Les patins sont fixés sur la pièce métallique par le moyen de vis telles 35 que 12 dans les figures 2 ou 3. The carriages include a metal part 2 which is embedded at each end in pads 1 made of teflon or any other material. These pads constitute wearing parts which slide into the appropriate housing of the profile. The pads are fixed to the metal part by means of screws such as 12 in FIGS. 2 or 3.
Lorsque le chariot porte le câble électrique comme dans la figure 3, il est associé à une pince qui est une pièce métallique disposée dans la deuxième partie du profilé et qui est fixée de façon réglable sur le chariot par le moyen de vis écrous telles que 5. Entre la pince et le chariot on dispose le câble When the carriage carries the electric cable as in FIG. 3, it is associated with a clamp which is a metallic piece placed in the second part of the profile and which is fixed in an adjustable manner on the carriage by means of screw nuts such as 5 Between the clamp and the carriage we have the cable
d'alimentation électrique tel que 3 par exemple un ou plusieurs méplats. power supply such as 3 for example one or more flats.
En tête du mât, le chariot est lié au câble de traction et supporte un équipement, il est alors composé 5 comme l'indique la figure 2, de deux éléments semblables coulissant chacun par le moyen des patins dans la partie correspondante du profilé. Par ce moyen le profilé peut porter aussi bien les deux types de chariots. En poutre le chariot porte, dans sa partie extérieure, un dispositif 24 qui coulisse autour de la partie supérieure 23 du profilé, permettant à celui-ci de ne pas se déformer en cas d'utilisation du système de freinage La sécurité est assurée par un système classique de freins tel que celui montré par la figure 5. Ce frein comporte deux pièces telles que 17 qui lorsque le câble 20 est sous tension sont maintenues dans la position verticale. Si le câble vient à se rompre, la tension n'existant plus, les ressorts tels que 21 repoussent les pièces qui prennent la position 19. Ces pièces comportent des surfaces crantées telles At the head of the mast, the carriage is linked to the traction cable and supports an equipment, it is then composed, as shown in FIG. 2, of two similar elements each sliding by means of the pads in the corresponding part of the profile. By this means the profile can carry both types of trolleys. In beam, the carriage carries, in its outer part, a device 24 which slides around the upper part 23 of the profile, allowing the latter not to be deformed when the braking system is used. Safety is ensured by a conventional brake system such as that shown in FIG. 5. This brake comprises two parts such as 17 which, when the cable 20 is under tension, are kept in the vertical position. If the cable breaks, the tension no longer existing, the springs such as 21 repel the parts which take position 19. These parts have notched surfaces such
que 18 qui viennent alors frotter contre une paroi 22 et provoquent un blocage de l'ensemble. that 18 which then rub against a wall 22 and cause a blockage of the assembly.
Cette paroi 22 peut être assurée de différentes manières. Ce peut être la surface 11 qui limite les deux parties du profilé. Mais les pièces 17 étant alors disposées horizontalement ce peut être le fond du This wall 22 can be provided in different ways. It may be the surface 11 which limits the two parts of the profile. But the parts 17 then being arranged horizontally, this may be the bottom of the
profilé sur la surface de freinage 26, lequel est alors dimensionné à cet effet. profiled on the braking surface 26, which is then dimensioned for this purpose.
Lorsqu'on utilise la partie 11 il est nécessaire d'assurer le maintien de l'écartement du profilé. Cela est obtenu en installant sur la partie extérieure du chariot de tête un équipement tel que celui représenté en 20 24 dans la figure 2. When using part 11 it is necessary to maintain the spacing of the profile. This is achieved by installing equipment on the outside of the head carriage such as that shown at 20 24 in Figure 2.
Le Profilé a également pour fonction de protéger les câbles électriques contre le vent et, en fonction de son positionnement, contre les UV. En outre, toujours selon sa disposition, il les cache aux.yeux des usagers. En outre, on peut l'équtiper en partie basse accessible au public, d'un couvercle spécifique The Profile also has the function of protecting electric cables against the wind and, depending on its position, against UV. In addition, always according to his disposition, he hides them from the eyes of the users. In addition, it can be fitted in the lower part accessible to the public, with a specific cover
amovible qui est enlevé dans les manoeuvres de descente ou de montée.. removable which is removed during descent or ascent maneuvers.
