Abstract

The invention relates to a device for raising a mast from a ground lowered position to a raised position at which it is supported on a base. The lower end of the mast is supported on the base by a connecting link comprising an upper fork and a lower fork joined by a link. The lower fork is fixed relative to the mast, but can be articulated with the mast about a mast-raising axis. The upper fork of the connecting link is connected to the lower part of an arm of a lever along a folding axis which axis is orthogonal to the mast-raising axis.

Description

L'invention se rapporte à.un dispositif de relevage d'un mât et au mât relevé à l'aide d'un tel dispositif.The invention relates to a device for lifting a mast and to the mast raised using such a device.

Elle se rapporte également aux mâts pourvus de ce dispositif. Elle s'applique plus particulièrement mais non exclusivement aux mâts d'antennes émettrices et/ou réceptrices provisoires utilisées à des fins tant militaires que civiles.It also relates to masts provided with this device. It applies more particularly but not exclusively to the masts of transmitting and / or provisional receiving antennas used for both military and civil purposes.

Pour disposer d'antennes provisoires, transportables et de mise en oeuvre facile et rapide, on utilise de plus en plus pour les supporter des mâts légers en matériau composite, tel des fibres associées à une résine.To have temporary antennas, transportable and easy and quick to use, it is increasingly used to support light masts of composite material, such as fibers associated with a resin.

Lors de leur utilisations, ils sont maintenus verticaux par. un haubanage.When in use, they are kept vertical by. a guy line.

Sur les lieux d'utilisation, le mât est tout d'abord couché au sol pour être équipé des antennes et des câbles de haubanage. Pour pouvoir être relevé, celui-ci est classiquement pourvu, d'une part, d'une embase articulée autour d'un axe horizontal traversant la dite embase et d'un sabot ancré dans le sol et, d'autre part, d'au moins un câble fixé près de la tête du mât et sur lequel depuis la base de ce mât, on exerce une traction. Cependant, au début du levage, le cordage est sensiblement parallèle au mât et, de ce fait, pour obtenir un couple suffisant au levage, il faut exercer une force de traction très importante. Pour remédier à cet inconvénient, perpendiculairement à l'axe du mât et dans son plan de basculement, on associe à son embase un bras de levier à l'extrémité supérieure duquel on fixe, d'une part, l'une des extrémités du câble dont l'autre extrémité est fixée sensiblement à mi hauteur du mât et, d'autre part, l'une des extrémités d'un câble dont l'autre extrémité est saisie par un moyen de traction tel un treuil.At the places of use, the mast is first laid down on the ground to be equipped with antennas and guying cables. To be able to be raised, it is conventionally provided, on the one hand, with a base articulated around a horizontal axis passing through said base and with a shoe anchored in the ground and, on the other hand, at least one cable fixed near the head of the mast and on which from the base of this mast is exerted a traction. However, at the start of lifting, the rope is substantially parallel to the mast and, therefore, to obtain sufficient torque when lifting, it is necessary to exert a very large pulling force. To remedy this drawback, perpendicular to the axis of the mast and in its tilting plane, there is associated with its base a lever arm at the upper end of which one fixes, on the one hand, one of the ends of the cable whose other end is fixed substantially at mid-height of the mast and, on the other hand, one end of a cable, the other end of which is gripped by a traction means such as a winch.

Pour être associé à l'embase du mât, ce bras est généralement pourvu à son extrémité basse d'une simple chape qui coiffe latéralement le mât ou son embase et la chape de son sabot ancré au sol pour bénéficier de l'axe d'articulation de cette embase lors de son accompagnement du mât pendant son basculement.To be associated with the base of the mast, this arm is generally provided at its lower end with a simple yoke which covers the mast or its base laterally and the yoke of its shoe anchored to the ground to benefit from the axis of articulation of this base when accompanying the mast during its tilting.

Sous l'effet combiné de l'effort de traction et du poids des antennes associées à son sommet, le mât subit une déformation qui peut même, vue son intensité, devenir permanente, voire même conduire à sa rupture.Under the combined effect of the tensile force and the weight of the antennas associated with its top, the mast undergoes a deformation which can even, given its intensity, become permanent, or even lead to its rupture.

Par ailleurs, pour être efficace, un tel bras de levier doit avoir une longueur importante de l'ordre de plusieurs mètres, ce qui, malheureusement, reportant très haut le sommet du bras, rend mal aisé la fixation tant du câble relié au mât que celui relié au treuil.Furthermore, to be effective, such a lever arm must have a significant length of the order of several meters, which, unfortunately, deferring the top of the arm very high, makes it difficult to fix both the cable connected to the mast and the one connected to the winch.

Un résultat que l'invention vise à obtenir est un dispositif du type précité, qui facilite le relevage d'un mât en prévenant toute déformation permanente susceptible de lui être imprimée par la charge qu'il supporte.A result which the invention aims to obtain is a device of the aforementioned type, which facilitates the lifting of a mast by preventing any permanent deformation liable to be imparted to it by the load which it supports.

Un autre résultat que l'invention vise à obtenir est un dispositif du type précitée auquel il est simple de fixer les câbles reliés au mât et au treuil.Another result which the invention aims to obtain is a device of the aforementioned type to which it is simple to fix the cables connected to the mast and the winch.

A cet effet, l'invention a pour objet un dispositif de relevage du type précité, notamment caractérisé en ce qu'il comprend des moyens de repliage du levier autour d'un axe qui est orthogonal à l'axe d'articulation de la base du dit levier.To this end, the subject of the invention is a lifting device of the aforementioned type, in particular characterized in that it comprises means for folding the lever around an axis which is orthogonal to the axis of articulation of the base. of the said lever.

Elle a également pour objet le mât pourvu de ce dispositif.It also relates to the mast provided with this device.

Elle sera bien comprise à l'aide de la description ci-après faite, à titre d'exemple non limitatif, en regard du dessin ci-annexé qui représente schématiquement :

  • - figure 1: vu en perspective, un mât relevé au moyen du dispositif de l'invention,
  • - figure 2: une vue de détail du dispositif,
  • - figures 3, 4 et 5: le mât couché au sol avant son précintrage en vues respectivement de dessus, de face et de profil,
  • - figures 6 et 7: le mât couché après son précintrage en vues respectivement de faceet de profil.
It will be clearly understood with the aid of the description below, given by way of nonlimiting example, with reference to the attached drawing which schematically represents:
  • - Figure 1: seen in perspective, a mast raised using the device of the invention,
  • FIG. 2: a detailed view of the device,
  • - Figures 3, 4 and 5: the mast lying on the ground before pre-bending in top, front and side views respectively,
  • - Figures 6 and 7: the mast lying after pre-bending in front and profile views respectively.

En se reportant au dessin, on voit qu'un mât 1 est tout d'abord couché au sol pour être équipé de son antenne 3 et être associé à l'axe d'articulation 4 d'une chape 5 portée par un sabot 6 ancré au sol 2.Referring to the drawing, we see that a mast 1 is first of all lying on the ground to be equipped with its antenna 3 and to be associated with the articulation axis 4 of a yoke 5 carried by a shoe 6 anchored on the ground 2.

Pour le relevage du mât, on agit sur au moins un câble 7, 8 qui, par une extrémité 9, 10, est fixé à une certaine distance de la base du mât et qui, pai son autre extrémité 11, 12, est fixé en tête 13 d'un bras de levier 14 perpendiculaire à l'axe du mât et dont la base présente une chape 15 coiffant latéralement le mât pour s'articuler avec lui autour de l'axe 4 de la chape 5 du sabot 6 mais pour être immobilisé par rapport au mât. Généralement, le levier n'est pas manoeuvré à la main mais par un moyen de traction tel un treuil 16 qui, avec son câble 17 est intercalé entre la tête 13 du levier 14 et un point 18 d'ancrage au sol situé dans le prolongement axial du mât et du côté de sa base.For lifting the mast, action is taken on at least one cable 7, 8 which, by one end 9, 10, is fixed at a certain distance from the base of the mast and which, by its other end 11, 12, is fixed in head 13 of a lever arm 14 perpendicular to the axis of the mast and the base of which has a clevis 15 laterally covering the mast to articulate with it around the axis 4 of the clevis 5 of the shoe 6 but to be immobilized relative to the mast. Generally, the lever is not operated by hand but by a traction means such as a winch 16 which, with its cable 17 is interposed between the head 13 of the lever 14 and a point 18 for anchoring to the ground located in the extension axial of the mast and the side of its base.

L'actionnement du treuil 16 appelle alors le levier qui, par les câbles 7, 8, relève progressivement le mât.The actuation of the winch 16 then calls the lever which, by the cables 7, 8, gradually raises the mast.

Pour faciliter l'accés en tête du levier 14, celui-ci est pourvu de moyens 19, 20, 21 de repliage du levier 14 autour d'un axe 20 qui est orthogonal à l'axe 4 d'articulation de la base du dit levier 14.To facilitate access to the head of the lever 14, the latter is provided with means 19, 20, 21 for folding the lever 14 around an axis 20 which is orthogonal to the axis 4 of articulation of the base of the said lever 14.

Ces moyens 19 à 21 scindent alors le levier en deux parties 22, 23 dont, d'une part, forme une embase 22 dont une extrémité porte la chape 15 s'articulant sur le sabot et l'autre une chape 19 portant l'axe 20 de repliage et, d'autre part, un bras 23 dont la base porte une pièce 21 traversée par l'axe de repliage et dont la tête reçoit le câble relié au mât et, s'il y a, celui relié au moyen de traction.These means 19 to 21 then split the lever into two parts 22, 23 of which, on the one hand, forms a base 22 of which one end carries the yoke 15 articulated on the shoe and the other a yoke 19 carrying the axis 20 for folding and, on the other hand, an arm 23 whose base carries a part 21 crossed by the folding axis and whose head receives the cable connected to the mast and, if there is one, that connected by means of traction.

De ce fait, le bras 23 peut, lors du montage, se replier vers le sol, latéralement au mât 1 ce qui facilite l'accés à la tête du levier.Therefore, the arm 23 can, during assembly, fold towards the ground, laterally to the mast 1 which facilitates access to the head of the lever.

De préférence, cette fixation se fera avec une légère tension. Pour éviter que, sous l'effet combiné de la traction et du poids, le mât fléchisse dangereusement, l'axe orthogonal 20 est situé à une distance suffisante de l'axe 4 d'articulation sur le sabot 6. De ce fait, avant relevage du mât, le redressement du levier 14 éloigne sa tête de sa base, ce qui tendera le câble reliant la tête du mât et accentuera ou provoquera automatiquement le précintrage du mât (figure 6).Preferably, this fixing will be done with a slight tension. To avoid that, under the combined effect of traction and weight, the mast bends dangerously, the orthogonal axis 20 is located at a sufficient distance from the axis 4 of articulation on the shoe 6. Therefore, before lifting the mast, the straightening of the lever 14 moves its head away from its base, which will stretch the cable connecting the head of the mast and will automatically accentuate or cause the pre-bending of the mast (Figure 6).
