Description

L'invention a trait à une nacelle élévatrice et à un procédé d'assemblage d'une superstructure de bâtiment au moyen d'une telle nacelle.The invention relates to a lifting platform and a method of assembling a building superstructure to by means of such a nacelle.

Dans le domaine de la construction de bâtiments industriels, tels que des hangars comprenant des superstructures métalliques, il est connu de monter des poteaux puis de relier les extrémités supérieures de ces poteaux grâce à des poutres. Pour ce faire on utilise classiquement une grue qui doit être fermement immobilisée par rapport au sol, par exemple au moyen de vérins, avant de pouvoir soulever une poutre. Un grutier ou un chauffeur spécialisé doit être employé pour déplacer ou piloter une telle grue, ce qui renchérit d'autant le prix de construction d'un bâtiment.In the field of building construction industrial, such as hangars with metal superstructures, it is known to mount posts then connect the upper ends of these posts thanks to beams. To do this we use conventionally a crane which must be firmly immobilized relative to the ground, for example by means of jacks, before to be able to lift a beam. A crane operator or a driver specialist must be used to move or pilot a such a crane, which increases the price of construction of a building.

Tel est en particulier le cas avec les grues connues de US-A-4,721,213 qui sont montées chacune sur un camion. En outre, dans cet art antérieur, les camions, sont immobilisés par des patins d'appui sur le sol lors du déploiement des mâts élévateurs. Les grues ne peuvent donc pas être déplacées lorsqu'elles sont en configuration de travail.This is in particular the case with known cranes of US-A-4,721,213 which are each mounted on a truck. Furthermore, in this prior art, trucks are immobilized by support pads on the ground during the deployment of lifting masts. Cranes therefore cannot not be moved when in configuration job.

C'est à ces inconvénients qu'entend plus particulièrement remédier l'invention en proposant un nouveau type de nacelle qui permet de se dispenser de l'utilisation d'une grue classique dans de nombreuses situations.It is to these disadvantages that most particularly remedy the invention by proposing a new type of gondola which allows to dispense with the use of a conventional crane in many situations.

Dans cet esprit, l'invention concerne une nacelle élévatrice qui comprend un ensemble auto-moteur apte à reposer sur le sol par des organes de liaison, cet ensemble étant équipé d'une structure apte à élever plus ou moins, par rapport à cet ensemble, un organe de support d'une charge, cet organe étant fixé ou articulé sur cette structure. Cette nacelle est caractérisée en ce que l'ensemble auto-moteur ou la structure élévatrice est pourvu de moyens de réception d'un signal émis par une télécommande et en ce que ces moyens de réception sont couplés à des moyens permettant de commander à la fois l'ensemble auto-moteur et la structure élévatrice pour le déplacement dans l'espace de l'organe de support, ces moyens de commande pouvant ainsi être activés par la télécommande.In this spirit, the invention relates to a nacelle which includes a self-propelled assembly capable of rest on the ground by connecting members, this set being equipped with a structure capable of raising more or less, with respect to this assembly, a support member of a load, this member being fixed or articulated on this structure. This nacelle is characterized in that the self-propelled assembly or the lifting structure is provided with means for receiving a signal emitted by a remote control and in that these reception means are coupled to means for controlling both the self-driving assembly and the lifting structure for the movement in space of the support member, these control means can thus be activated by the remote control.

Grâce à l'invention, la nacelle peut être pilotée par un opérateur se trouvant à bord d'une autre nacelle élévatrice, par exemple en hauteur dans une zone de jonction entre une poutre et la superstructure d'un bâtiment. Par la télécommande, l'opérateur peut ainsi manoeuvrer la nacelle conforme à l'invention pour pré-positionner une poutre par rapport à son environnement, sans avoir recours à une grue.Thanks to the invention, the nacelle can be controlled by an operator on board another nacelle lifting, for example in height in an area of junction between a beam and the superstructure of a building. By the remote control, the operator can thus maneuver the nacelle according to the invention to pre-position a beam in relation to its environment, without using a crane.

Selon des variantes de réalisation de l'invention, l'organe de support peut être formé par un ensemble de fourches monté sur la structure élévatrice, par un crochet monté sur un bras, lui-même fixé sur cette structure, ou par un plateau monté sur cette structure.According to alternative embodiments of the invention, the support member can be formed by a set of forks mounted on the lifting structure, by a hook mounted on an arm, itself fixed on this structure, or by a plate mounted on this structure.

La structure élévatrice peut être de type à mât télescopique, de type à ciseaux ou de type à mât articulé.The lifting structure can be of mast type telescopic, scissor type or articulated mast type.

L'invention concerne également un procédé d'assemblage d'une superstructure d'un bâtiment, dans lequel on fixe en hauteur un élément structurel. Ce procédé comprend des étapes consistant, pour un opérateur, à :

  • se positionner dans une zone de raccordement prévue de cet élément structurel avec le reste de la superstructure ;
  • commander, au moyen d'une télé-commande, une nacelle telle que précédemment décrite pour soulever et positionner cet élément par rapport à cette superstructure et
  • immobiliser cet élément dans la zone de raccordement précitée.
The invention also relates to a method of assembling a superstructure of a building, in which a structural element is fixed in height. This method comprises steps consisting, for an operator, in:
  • position itself in a planned connection area of this structural element with the rest of the superstructure;
  • control, by means of a remote control, a nacelle as previously described for lifting and positioning this element relative to this superstructure and
  • immobilize this element in the aforementioned connection area.

L'invention sera mieux comprise et d'autres avantages de celle-ci apparaítront plus clairement à la lumière de la description qui va suivre de deux modes de réalisation d'une nacelle conforme à son principe et de son mode de mise en oeuvre, donnée uniquement à titre d'exemple et faite en référence aux dessins annexés dans lesquels :

  • la figure 1 est une vue de principe de côté, dans une première position, d'une nacelle conforme à un premier mode de réalisation de l'invention ;
  • la figure 2 est une vue analogue à la figure 1 lorsque la nacelle est dans une seconde position, en cours d'utilisation lors du montage de la superstructure d'un bâtiment et
  • la figure 3 est une vue analogue à la figure 2 pour une nacelle conforme à un second mode de réalisation de l'invention.
The invention will be better understood and other advantages thereof will appear more clearly in the light of the following description of two embodiments of a nacelle in accordance with its principle and of its mode of implementation, given by way of example only and with reference to the appended drawings in which:
  • Figure 1 is a side view in principle, in a first position, of a nacelle according to a first embodiment of the invention;
  • FIG. 2 is a view similar to FIG. 1 when the nacelle is in a second position, in use during assembly of the superstructure of a building and
  • Figure 3 is a view similar to Figure 2 for a nacelle according to a second embodiment of the invention.

La nacelle 1 représentée aux figures 1 et 2 comprend un châssis 2 qui repose sur la surface S du sol par quatre roues dont deux sont visibles avec les références 3A et 3B. A la place de roues, le châssis 2 pourrait être équipé de chenilles formant organes de liaison au sol. La roue 3A est motrice, c'est-à-dire reliée à un moteur 4 intégré au châssis 2. La roue 3B est directrice, c'est-à-dire a une orientation variable par rapport au châssis 2, ceci permettant de diriger la nacelle 1.The nacelle 1 shown in Figures 1 and 2 includes a chassis 2 which rests on the surface S of the ground by four wheels, two of which are visible with references 3A and 3B. Instead of wheels, chassis 2 could be fitted with caterpillars forming bodies for connecting to the ground. The 3A wheel is drive, that is to say connected to a motor 4 integrated in the chassis 2. The wheel 3B is steerable, that is to say has a variable orientation with respect to chassis 2, this allowing to direct the nacelle 1.

Sur le châssis 2 est monté, avec possibilité de rotation autour d'un axe Z-Z' qui est vertical lorsque la surface S est horizontale, une embase 5 sur laquelle est articulé un mât télescopique 6. Le mât 6 est articulé sur l'embase 5 autour d'un axe X-X' perpendiculaire à l'axe Z-Z'. La double flèche F1 à la figure 2 représente le mouvement de rotation du mât 6 par rapport à l'axe X-X'. La double flèche F2 représente le mouvement de pivotement de l'embase 5 par apport au châssis 2.On the chassis 2 is mounted, with the possibility of rotation about an axis ZZ 'which is vertical when the surface S is horizontal, a base 5 on which is articulated a telescopic mast 6. The mast 6 is articulated on the base 5 around an axis XX 'perpendicular to the axis Z-Z'. The double arrow F 1 in FIG. 2 represents the rotational movement of the mast 6 relative to the axis XX ′. The double arrow F 2 represents the pivoting movement of the base 5 by contribution to the chassis 2.

La double flèche F3 représente un mouvement de déplacement de l'ensemble de la nacelle 1 par rapport à la surface S du sol, alors que la double flèche F4 représente les changements de direction possibles de la nacelle 1.The double arrow F 3 represents a movement of displacement of the whole of the nacelle 1 relative to the surface S of the ground, while the double arrow F 4 represents the possible changes of direction of the nacelle 1.

Le mât 6 est télescopique, en ce sens qu'il comprend un fût 61 articulé sur l'embase 5 et une partie 62 apte à coulisser à l'intérieur du fût 61 en étant commandé par tout moyen approprié, par exemple par un vérin hydraulique non représenté. La double flèche F5 représente la possibilité d'extension du mât 6.The mast 6 is telescopic, in that it comprises a barrel 61 articulated on the base 5 and a part 62 capable of sliding inside the barrel 61 while being controlled by any appropriate means, for example by a hydraulic cylinder not shown. The double arrow F 5 represents the possibility of extension of the mast 6.

A l'extrémité supérieure de la partie 62 est montée une structure à parallélogramme 63 qui supporte deux fourches dont une seule est représentée sur les figures avec la référence 7.At the upper end of part 62 is mounted a parallelogram structure 63 which supports two forks only one of which is shown in the figures with reference 7.

Conformément à l'invention, il est prévu un boítier de télécommande 10 destiné à être pris en mains par un opérateur O, alors que l'embase 5 est équipée d'un capteur 11 apte à recevoir les signaux radio-électriques émis par la télécommande 10 et à les transmettre par une liaison filaire 12 à une unité 13 de contrôle des mouvements de la nacelle 1. L'unité 13 peut commander le déplacement du châssis 2 dans le sens des flèches F3 et F4, le pivotement de l'embase 5 par rapport au châssis 2 selon la flèche F2 et l'élévation du mât 6 par rapport à l'embase 5 dans le sens des flèches F1 et F5. L'unité 13 permet également de commander le pivotement de la structure à parallélogramme 63 par rapport à la partie 62 du mât 6, ceci étant représenté par la double flèche F6 à la figure 2.According to the invention, there is provided a remote control unit 10 intended to be taken in hand by an operator O, while the base 5 is equipped with a sensor 11 capable of receiving the radioelectric signals emitted by the remote control 10 and to transmit them by a wire link 12 to a unit 13 for controlling the movements of the nacelle 1. The unit 13 can control the movement of the chassis 2 in the direction of the arrows F 3 and F 4 , the pivoting of the base 5 with respect to chassis 2 according to arrow F 2 and the elevation of the mast 6 with respect to base 5 in the direction of arrows F 1 and F 5 . The unit 13 also makes it possible to control the pivoting of the parallelogram structure 63 relative to the part 62 of the mast 6, this being represented by the double arrow F 6 in FIG. 2.

Il est ainsi possible de commander, à distance et par la télécommande 10, le positionnement dans l'espace des fourches 7 et d'une charge qu'elle supporte. It is thus possible to control, remotely and by the remote control 10, the positioning in space of forks 7 and a load it supports.

A la figure 2, il est représenté la mise en oeuvre de la nacelle 1 lors de la construction d'un bâtiment industriel comprenant un poteau P immobilisé par rapport à la surface S du sol grâce à un massif M. Une poutre P' en forme de C est destinée à être fixée au poteau P dans une zone Z voisine de son extrémité supérieure.In FIG. 2, the implementation of nacelle 1 during the construction of a building industrial including a pole P immobilized relative to the surface S of the ground thanks to a solid mass M. A beam P 'in form of C is intended to be fixed to the post P in a zone Z near its upper end.

L'opérateur O peut prendre position sur la plate-forme 22 d'une seconde nacelle 21 qui peut être de tout type connu, par exemple une nacelle dite à ciseaux. L'opérateur O peut ainsi intervenir dans la zone Z.The operator O can take position on the platform 22 of a second nacelle 21 which can be of any type known, for example a so-called scissor lift. The operator O can thus intervene in zone Z.

Grâce à la télécommande 10, l'opérateur O peut commander le déplacement dans l'espace de la poutre P' de façon à l'amener dans la zone Z dans laquelle il peut alors intervenir pour immobiliser la poutre P' sur le poteau P, par exemple au moyen de boulons. Les fourches passent ainsi de la position basse à la position haute représentées à la figure 2.Thanks to the remote control 10, the operator O can control the displacement in space of the beam P 'of way to bring it into zone Z where it can then intervene to immobilize the beam P 'on the column P, for example by means of bolts. The forks pass thus from the low position to the high position shown in the figure 2.

Ainsi, l'opérateur peut assembler la superstructure du bâtiment sans avoir recours à une grue dont le prix de revient horaire est élevé et sans avoir besoin des services d'un grutier spécialisé.Thus, the operator can assemble the superstructure of the building without having to use a crane whose price hourly returns are high and without the need for services a specialist crane operator.

Dans le second mode de réalisation de l'invention représenté à la figure 3, les éléments analogues à ceux du premier mode de réalisation portent des références identiques augmentées de 100. La nacelle 101 de ce mode de réalisation comprend un châssis 102 associé à une embase 105, le châssis reposant sur le sol grâce à des roues 103A et 103B. Un moteur 104 est incorporé au châssis 102 et un mât 106 est articulé sur l'embase 105. A l'extrémité supérieure du mât 106 est fixé rigidement un bras 108 assurant une liaison entre le mât 106 et un crochet 107 de type crochet de grue qui est de préférence articulé sur le bras 108. Le crochet 107 permet de soulever, grâce à un filin 109, une poutre P' à section en forme de I en vue de la positionner dans l'espace, comme cela ressort des deux positions représentées sur la figure 3.In the second embodiment of the invention shown in Figure 3, elements similar to those of first embodiment bear references identical increased by 100. The nacelle 101 of this mode of embodiment includes a frame 102 associated with a base 105, the chassis resting on the ground by means of wheels 103A and 103B. A motor 104 is incorporated into the chassis 102 and a mast 106 is articulated on base 105. At the end upper mast 106 is rigidly fixed an arm 108 ensuring a connection between the mast 106 and a hook 107 of type crane hook which is preferably hinged on the arm 108. The hook 107 makes it possible to lift, thanks to a rope 109, a beam P ′ with an I-shaped section in order to position it in space, as shown by the two positions shown in figure 3.

La nacelle 101 est équipée d'un capteur 111 relié par une liaison filaire 112 à une unité 113 de commande de la position dans l'espace du crochet 107.The nacelle 101 is equipped with a sensor 111 connected by a wired link 112 to a unit 113 for controlling the space position of the hook 107.

Le capteur 111 est apte à recevoir et à transmettre à l'unité 113 des signaux émis par une télécommande 110 qu'un opérateur .0 peut emmener avec lui lorsqu'il se trouve sur la plate-forme 122 d'une seconde nacelle 121.The sensor 111 is able to receive and transmit to the unit 113 of the signals emitted by a remote control 110 that a operator .0 can take with him when he is on the platform 122 of a second nacelle 121.

Comme précédemment, la nacelle 101 peut être utilisée pour positionner en hauteur la poutre P' par rapport à la superstructure d'un bâtiment en cours de construction.As before, the nacelle 101 can be used to position the beam P 'in height relative to the superstructure of a building under construction.

L'invention n'est pas limitée aux modes de réalisation représentés et, à la place des fourches 7 ou du crochet 107, on pourrait utiliser un plateau monté en partie supérieure d'une structure élévatrice. A ce sujet, la structure élévatrice n'est pas nécessairement un mât télescopique. Il peut s'agir d'une structure du type à ciseaux, telle que représentée pour la seconde nacelle visible aux figures 2 et 3. Cette structure pourrait également être du type à mât articulé ou de tout autre type connu.The invention is not limited to the embodiments shown and, instead of the forks 7 or the hook 107, we could use a partially mounted tray upper of an elevating structure. On this subject, the lifting structure is not necessarily a mast telescopic. It can be a structure of the type to scissors, as shown for the second basket visible in Figures 2 and 3. This structure could also be of the articulated mast type or any other type known.
