Abstract

The invention relates to multi-element masts and a method of raising a multi-element mast by adding successive elements wherein a direction of traction (15) to be exerted by at least one operator on the free portion (16) of a tieline (8) emerging from a support plate (7) that enables raising the mast elements by the ascending movement of the plate (7) is defined and on a locking device (18) is fixed with respect to a mast guide shaft (4) and allows the portion of the tieline (8) emerging from the support plate (7) to unwind when the support plate is engaged and the tieline is pulled in the defined direction of traction (15). The locking device also permits locking of the tieline (8) against translation in the direction opposite the direction of traction previously defined, substantially at the end of any traction action. A traction device (20) is provided which includes at least one handle element (21) enabling it to be grasped by at least one operator and at least one locking device (22), which, symmetrically to the locking device fixed to the mast guide shaft (4), first, enables locking the traction device (20) via the bias of the locking means against translation on the tieline when the operator(s) urges the tieline in the predefined traction direction (15), and, second, enables free sliding of the traction device on the tieline (8) when the operator(s) suitably holding the free end (11) of the tieline (8) tends to displace the traction device on the tieline (8) in the opposite direction from the defined traction direction (15).

Description

L'invention se rapporte à un procédé de levage d'un levage d'un mât en plusieurs éléments par ajouts d'éléments successifs à sa base ainsi qu'aux moyens pour la mise en oeuvre du procédé et aux mâts pourvus de ces moyens.The invention relates to a method of lifting a lifting of a mast in several elements by adding successive elements to its base as well as to the means for implementing the method and to the masts provided with these means.

Elle s'applique plus particulièrement mais non exclusivement aux procédés de levage des éléments des mâts destinés à supporter et orienter des antennes émettrices et/ou réceptrices provisoires utilisées à des fins tant militaires que civiles.It applies more particularly but not exclusively to the methods of lifting the elements of the masts intended to support and orient temporary transmitting and / or receiving antennas used for both military and civil purposes.

Du fait du caractère provisoire de l'installation de ces antennes, il est connu pour faciliter leur transport, de réaliser ces mâts en plusieurs éléments généralement cylindriques qui, lors de l'utilisation, sont placés bout à bout et sont à chacune de leurs jonctions bout à bout, assemblés par engagement, dans l'un des éléments, d'un manchon porté par l'autre élément.Due to the provisional nature of the installation of these antennas, it is known to facilitate their transport, to produce these masts in several generally cylindrical elements which, during use, are placed end to end and are at each of their junctions end to end, assembled by engagement, in one of the elements, of a sleeve carried by the other element.

Pour un tel mât, on commence par assembler les éléments de tête supportant l'antenne, puis on engage ce groupe d'éléments dans un fût vertical prenant appui au sol par un piétement.For such a mast, we start by assembling the head elements supporting the antenna, then we engage this group of elements in a vertical shaft bearing on the ground by a base.

Ensuite, pour élever l'antenne à la hauteur souhaitée, par la base de ce fût, on engage successivement les éléments supplémentaires nécessaires et par cela on remonte progressivement la tête du mât.Then, to raise the antenna to the desired height, by the base of this barrel, the necessary additional elements are successively engaged and by this the head of the mast is gradually raised.

Bien entendu, pour démonter le mât, on procéde à l'inverse. Pour élever la tête du mât à chaque fois de la hauteur d'un élément engagé dans le fût, on utilise un dispositif de levage principalement constitué d'une platine d'appui reliée par un lien à au moins un organe qui permet d'appeler la dite platine vers la base du fût.Of course, to dismantle the mast, we proceed in reverse. To raise the head of the mast each time from the height of an element engaged in the barrel, a lifting device is used mainly consisting of a support plate connected by a link to at least one member which makes it possible to call said platinum towards the base of the barrel.

Généralement, ces organes sont constitués par des treuils qui sont actionnés par le ou les opérateurs qui assemblent le mât. Pour constituer le treuil, on fait généralement appel à un mécanisme qui comprend un tambour d'enroulement du lien, lequel tambour est entraîné en rotation par un dispositif de démultiplication de l'effort à exercer sur le lien.Generally, these organs are constituted by winches which are actuated by the operator or operators who assemble the mast. To constitute the winch, use is generally made of a mechanism which comprises a drum for winding the link, which drum is driven in rotation by a device for reducing the force to be exerted on the link.

Bien entendu, le mécanisme comprend également un dispositif à cliquet qui permet d'éviter le déroulement intempestif du lien sur le tambour, sous l'action de la charge levée.Of course, the mechanism also includes a ratchet device which makes it possible to avoid untimely unwinding of the link on the drum, under the action of the load lifted.

Les mécanismes de levage ainsi conçus donnent de bons résultats notamment dans le cas de levage de fortes charges.The lifting mechanisms thus designed give good results, particularly in the case of lifting heavy loads.

Néanmoins, on leur reproche d'être relativement onéreux compte tenu de leur complexité.However, they are criticized for being relatively expensive given their complexity.

Un résultat que l'invention vise à obtenir est un procédé de levage qui met en oeuvre des moyens simples et peu onéreux tout en permettant d'assurer l'érection de mâts dans de très bonnes conditions de sécurité pour le personnel opérant.A result which the invention aims to obtain is a lifting method which employs simple and inexpensive means while making it possible to ensure the erection of masts under very good safety conditions for the operating personnel.

A cet effet, l'invention a pour objet un procédé du type précité notamment caractérisé en ce que :
- on définit le sens de la traction qui, exercée par au moins un opérateur sur la partie du lien issue de la platine d'appui, permet d'obtenir le levage des éléments de mât par le mouvement ascendant de la platine,
- on fixe, par rapport au fût de guidage, un dispositif d'arrêt qui permet d'une part de laisser défiler la partie du lien issue de la platine d'appui lorsqu'on engage cette dernière et qu'on la sollicite dans le sens de traction défini et, d'autre part, de bloquer cette partie de lien en translation dans le sens opposé au sens de traction, précédemment défini, sensiblement à l'issue de toute action de traction,
- on saisit l'extrémité libre du lien à l'aide d'un dispositif de traction qui comprend :
. au moins un élément permettant sa préhension par au moins un opérateur et,
. au moins un moyen qui, symétriquement au dispositif d'arrêt fixé au fût, d'une part, permet le blocage en translation du présent dispositif de traction par rapport au lien, lorsque, par le biais du dit dispositif, au moins un opérateur sollicite le lien dans le sens de traction prédéfini, et, d'autre part, permet le libre coulissement du dit dispositif de traction sur le lien lorsqu'au moins un opérateur maintenant convenablement l'extrémité libre du lien tend à déplacer le dit dispositif de traction sur le lien dans le sens opposé au sens de traction défini.To this end, the subject of the invention is a method of the aforementioned type, in particular characterized in that:
the direction of traction is defined which, exerted by at least one operator on the part of the link coming from the support plate, makes it possible to obtain the lifting of the mast elements by the upward movement of the plate,
- a stop device is fixed with respect to the guide barrel which, on the one hand, allows the part of the link coming from the support plate to pass through when the latter is engaged and is urged into the defined direction of traction and, on the other hand, to block this link part in translation in the opposite direction to the previously defined direction of traction, substantially at the end of any traction action,
- the free end of the link is grasped using a traction device which comprises:
. at least one element allowing it to be grasped by at least one operator and,
. at least one means which, symmetrically to the stop device fixed to the barrel, on the one hand, allows the locking in translation of this traction device relative to the link, when, by means of said device, at least one operator requests the link in the predefined direction of traction, and, on the other hand, allows the free sliding of said traction device on the link when at least one operator correctly holding the free end of the link tends to move said traction device on the link in the opposite direction to the defined direction of traction.

L'invention a également pour objet les moyens pour la mise en oeuvre du procédé, lesquels moyens sont caractérisés en ce qu'ils comprennent, en combinaison :
- fixe par rapport au fût de guidage, un dispositif d'arrêt qui permet de laisser défiler le lien lorsque ce dernier est sollicité par au moins un opérateur dans le sens de traction et de bloquer le lien en translation dans le sens opposé au sens de traction tel que précédemment défini sensiblement à l'issue de toute action de traction,
- engagé sur le même lien, un dispositif de traction qui comprend :
. au moins un élément permettant sa préhension par au moins un opérateur effectuant le levage,
. au moins un moyen qui, symétriquement au dispositif d'arrêt du fût, d'une part, permet le blocage en translation du présent dispositif de traction sur le lien, lorsque, par le biais du dit dispositif, au moins un opérateur sollicite le lien dans le sens de traction prédéfini, et, d'autre part, permet le coulissement du dit dispositif de traction sur le lien lorsque le et/ou les opérateurs maintenant convenablement l'extrémité libre du lien tendent à déplacer le dit dispositif de traction sur le lien dans le sens opposé au sens de traction.The subject of the invention is also the means for implementing the method, which means are characterized in that they comprise, in combination:
- fixed relative to the guide shaft, a stop device which allows the link to run when the latter is requested by at least one operator in the pulling direction and to block the link in translation in the opposite direction to the direction of traction as previously defined substantially at the end of any traction action,
- engaged on the same link, a traction device which includes:
. at least one element allowing its gripping by at least one operator carrying out the lifting,
. at least one means which, symmetrically with the barrel stop device, on the one hand, allows the locking in translation of this traction device on the link, when, by means of said device, at least one operator requests the link in the predefined direction of traction, and, on the other hand, allows said traction device to slide on the link when the and / or the operators holding the free end of the link properly tend to move said traction device on the link in the opposite direction to the direction of traction.

Dans une variante de réalisation, ces moyens comprennent en outre un dispositif de démultiplication de l'effort de traction de levage, lequel dispositif consiste en une multiplicité de poulies autour desquelles on passe le lien et qui, disposées au niveau de la base du fut et de la platine, forment un palan démultiplicateur.In an alternative embodiment, these means further comprise a device for multiplying the lifting traction force, which device consists of a multiplicity of pulleys around which the link is passed and which, arranged at the base of the barrel and the stage, form a multiplier hoist.

L'invention sera mieux 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 : un synoptique du procédé,
  • - figure 2 : une forme de mise en oeuvre du procédé de l'invention.
The invention will be better understood with the aid of the description below given by way of nonlimiting example, with reference to the appended drawing which schematically represents:
  • - Figure 1: a block diagram of the process,
  • - Figure 2: a form of implementation of the method of the invention.

En se reportant au dessin, on voit qu'un dispositif 1 de levage des éléments 2 d'un mât 3 constitué d'éléments assemblés bout à bout comprend classiquement un fût vertical 4 prenant appui au sol par un piétement 5.Referring to the drawing, it can be seen that a device 1 for lifting the elements 2 of a mast 3 consisting of elements assembled end to end conventionally comprises a vertical barrel 4 bearing on the ground by a base 5.

Pour constituer le mât 3, on commence classiquement par assembler les éléments de tête du mât, puis on engage ce groupe d'éléments dans le fût vertical de guidage.To constitute the mast 3, one conventionally begins by assembling the head elements of the mast, then engaging this group of elements in the vertical guide barrel.

Ensuite, pour éléver les éléments de tête à la hauteur souhaitée, par la base 6 du fût 4, on engage successivement les éléments supplémentaires nécessaires et, par cela, on remonte progressivement la tête du mât.Then, to raise the head elements to the desired height, by the base 6 of the barrel 4, the additional elements necessary are successively engaged and, by this, the head of the mast is gradually raised.

Pour élever la tête du mât à chaque fois de la hauteur d'un élément 2 engagé dans le fût 1, on utilise un dispositif de levage qui comprend une platine d'appui 7 reliée par un lien 8 à au moins un organe 9 qui permet d'exercer une traction sur le lien 8 et par cela d'appeler la platine 7 vers la base 6 du fût 4.To raise the head of the mast each time from the height of an element 2 engaged in the barrel 1, a lifting device is used which comprises a support plate 7 connected by a link 8 to at least one member 9 which allows to exert a traction on the link 8 and by that to call the plate 7 towards the base 6 of the barrel 4.

Tel que cela apparaît sur le dessin, l'une (10) des extrémités 10, 11 du lien 8 est classiquement ancrée à la base 6 du fut 4 et, le dit lien 8 passe sous la platine 7 dans des poulies de renvoi 12 puis dans une poulie 13 dont le support est ancré à la base 6 du fût et qui permet quant à elle de dévier le lien vers l'organe d'appel 9.As shown in the drawing, one (10) of the ends 10, 11 of the link 8 is conventionally anchored to the base 6 of the barrel 4 and, the said link 8 passes under the plate 7 in return pulleys 12 then in a pulley 13, the support of which is anchored to the base 6 of the barrel and which in turn allows the link to be deflected towards the call member 9.

Au lieu d'utiliser comme organe d'appel 9 un treuil, pour exercer sur le lien 8 la traction de levage, selon l'invention :
- on définit 14 le sens de la traction 15 qui, exercée par un et/ou plusieurs opérateurs sur la partie libre 16 du lien 8, permet d'obtenir le levage des éléments de mât, par le mouvement ascendant de la platine 7,
- on fixe par rapport au fût de guidage 4, un dispositif d'arrêt 18 qui permet, d'une part, de laisser défiler la partie du lien issue de la platine d'appui 7 lorsqu'on y engage (17) cette dernière et qu'on la sollicite dans le sens de traction 15 défini ci-dessus et, d'autre part, de bloquer le lien 8 en translation dans le sens opposé au sens de traction, précédemment défini, sensiblement à l'issue de toute action de traction,
- on saisit 19 l'extrémité libre du lien à l'aide d'un dispositif 20 de traction qui comprend :
. au moins un élément 21 permettant sa préhension par au moins un opérateur,
. au moins un moyen 22 qui, symétriquement au dispositif d'arrêt fixé au fût, d'une part, permet le blocage en translation du présent dispositif 20 de traction sur le lien, lorsque, par le biais du dit dispositif, le et/ou les opérateurs sollicitent le lien dans le sens de traction 15 prédéfini, et, d'autre part, permet le libre coulissement du dit dispositif de traction sur le lien 8 lorsque le et/ou les opérateurs maintenant convenablement l'extrémité libre 11 du lien 8 tendent à déplacer le dit dispositif de traction sur le lien 8 dans le sens opposé au sens de traction 15.Instead of using a winch as a caller 9, to exert lifting traction on the link 8, according to the invention:
the direction of traction 15 is defined 14 which, exerted by one and / or more operators on the free part 16 of the link 8, makes it possible to obtain the lifting of the mast elements, by the upward movement of the plate 7,
- Is fixed relative to the guide shaft 4, a stop device 18 which allows, on the one hand, to let scroll the part of the link from the support plate 7 when engaged (17) the latter and that it is requested in the direction of traction 15 defined above and, on the other hand, to block the link 8 in translation in the direction opposite to the direction of traction, previously defined, substantially at the end of any action traction,
- the free end of the link is grasped 19 using a traction device 20 which comprises:
. at least one element 21 allowing it to be grasped by at least one operator,
. at least one means 22 which, symmetrically to the stop device fixed to the barrel, on the one hand, allows the locking in translation of the present traction device 20 on the link, when, by means of said device, the and / or the operators request the link in the predefined pulling direction 15, and, on the other hand, allow the said sliding device to slide freely on the link 8 when the and / or the operators correctly maintain the free end 11 of the link 8 tend to move said traction device on the link 8 in the opposite direction to the direction of traction 15.

Dans un mode préféré de mise en oeuvre du procédé de l'invention, avant de placer (17) le lien 8 issu de la platine d'appui 7 dans un dispositif d'arrêt 18 tel que défini précédemment, on constitue (23) au niveau du fût de guidage 3 et de la platine d'appui 7 un dispositif 24 de démultiplication de l'effort de traction à exercer par le et/ou les opérateurs, lequel dispositif consiste en une multiplicité 25 de poulies 12, 13 autour desquelles on passe le lien 8 et qui, disposées au niveau de la base du fût 4 et de la platine d'appui 7, forment un palan démultiplicateur.In a preferred embodiment of the method of the invention, before placing (17) the link 8 coming from the support plate 7 in a stop device 18 as defined above, one constitutes (23) at level of the guide barrel 3 and of the support plate 7 a device 24 for reducing the traction force to be exerted by the and / or the operators, which device consists of a multiplicity 25 of pulleys 12, 13 around which passes the link 8 and which, arranged at the base of the barrel 4 and the support plate 7, form a reduction gear hoist.

Pour appeler la platine 7 vers la base 6 du fût, il suffit donc à l'opérateur, de préférence, après avoir pris soin d'engager le lien dans le dispositif d'arrêt 18, de saisir d'une main le dispositif de traction 20 et de l'autre main, la partie libre 16 du dit lien, d'exercer un mouvement de traction sur le lien grace à un dispositif de traction puis, au terme de ce mouvement, de déplacer le dispositif de traction sur le lien 8 en maintenant l'extrémité libre 11 du lien 8 et d'exercer à nouveau une traction et ainsi de suite jusqu'à ce que la platine soit en position voulue.To call the plate 7 towards the base 6 of the barrel, it is therefore sufficient for the operator, preferably, after having taken care to engage the link in the stop device 18, to grasp the traction device with one hand 20 and with the other hand, the free part 16 of the said link, to exert a traction movement on the link using a traction device then, at the end of this movement, to move the traction device on the link 8 maintaining the free end 11 of the link 8 and exerting traction again and so on until the plate is in the desired position.

Lors du démontage du mât, l'opérateur doit contrôler la descente des éléments de mât.When dismantling the mast, the operator must control the descent of the mast elements.

Pour cela, il contrôle le défilement du lien 8 en engageant et/ou en dégageant celui-ci du dispositif d'arrêt 18. Les moyens pour la mise en oeuvre du procédé comprennent en combinaison :
- fixe par rapport au fût de guidage 4, un dispositif d'arrêt 18 qui permet de laisser défiler le lien 8 lorsque ce dernier est sollicité par le et/ou les opérateurs dans le sens de traction 15 défini et de bloquer le lien 8 en translation dans le sens opposé au sens de traction précédemment défini sensiblement à l'issue de toute action de traction de levage,
- un dispositif de traction 20 qui comprend :
. au moins un élément 21 permettant sa préhension par le et/ou les opérateurs effectuant le levage,
. au moins un moyen 22 qui, symétriquement au dispositif d'arrêt du fût, d'une part, permet le blocage en translation du présent dispositif de traction 20 sur le lien 8, lorsque, par le biais du dit dispositif, le et/ou les opérateurs sollicitent le lien 8 dans le sens de traction 15 prédéfini, et, d'autre part, permet le coulissement du dit dispositif de traction sur le lien 8 lorsque le et/ou les opérateurs maintenant convenablement l'extrémité libre 11 du lien 8 tendent à déplacer le dit dispositif de traction sur le lien 8 dans le sens opposé au sens de traction 15.For this, it controls the running of the link 8 by engaging and / or disengaging it from the stop device 18. The means for implementing the method comprise in combination:
- fixed relative to the guide barrel 4, a stop device 18 which allows the link 8 to run when the latter is requested by the and / or the operators in the defined direction of traction 15 and to block the link 8 in translation in the opposite direction to the direction of traction previously defined substantially at the end of any lifting traction action,
a traction device 20 which comprises:
. at least one element 21 allowing it to be grasped by the and / or the operators performing the lifting,
. at least one means 22 which, symmetrically with the barrel stop device, on the one hand, allows the locking in translation of this traction device 20 on the link 8, when, by means of said device, the and / or the operators request the link 8 in the predefined pulling direction 15, and, on the other hand, allow the said traction device to slide on the link 8 when the and / or the operators correctly maintain the free end 11 of the link 8 tend to move said traction device on the link 8 in the opposite direction to the direction of traction 15.

Dans une variante de réalisation, les moyens comprennent en outre, un dispositif de démultiplication 24 de l'effort de traction de levage, lequel dispositif consiste en une multiplicité de poulies 12, 13 autour desquelles on passe le lien 8 et qui, disposées au niveau de la base 6 du fut et de la platine 7, forment un palan démultiplicateur.In an alternative embodiment, the means further comprise a device for reducing the lifting traction force 24, which device consists of a multiplicity of pulleys 12, 13 around which the link 8 is passed and which, arranged at the level from the base 6 of the barrel and from the plate 7, form a multiplier hoist.

On réalisera facilement l'invention, en utilisant, pour constituer le dispositif d'arrêt 18, un taquet coinceur du type de ceux utilisés en navigation à voile et, pour constituer le dispositif de traction 20, une poignée autobloquante du type de celle utilisée en escalade (non représentée) par les pratiquants de ce sport et en montant ces éléments de manière à ce qu'ils travaillent symétriquement.The invention will easily be realized by using, to constitute the stop device 18, a cleat cleat of the type used in sailing and, to constitute the traction device 20, a self-locking handle of the type that used in climbing (not shown) by the practitioners of this sport and by mounting these elements so that they work symmetrically.

De préférence, le lien utilisé dans ce cas est du type des cordages d'escalade.Preferably, the link used in this case is of the type of climbing ropes.

L'homme de l'art est bien entendu à même de déterminer les moyens les plus appropriés pour constituer chacun des dispositifs précités.Those skilled in the art are of course able to determine the most appropriate means for constituting each of the aforementioned devices.

En ce qui concerne le dispositif de démultiplication 24, l'homme de l'art est également à même de déterminer le nombre de poulies constitutives du palan en fonction de la démultiplication souhaitée pour l'effort de traction.With regard to the reduction device 24, those skilled in the art are also able to determine the number of pulleys constituting the hoist as a function of the reduction desired for the tensile force.
