Description

L'invention a trait à une nacelle élévatrice pour préparation de commande ou travaux de construction ainsi qu'à son utilisation.The invention relates to a lifting platform for order preparation or construction work and its use.

Il est connu d'utiliser une nacelle élévatrice, dite préparateur de commande, pour accéder aux rayonnages d'un entrepôt de stockage et y prélever certains articles. Une telle nacelle comprend une plateforme sur laquelle se tient généralement un opérateur. Une nacelle doit donc être prévue pour chaque opérateur, ce qui s'avère onéreux et encombre les allées d'un entrepôt de stockage.It is known to use a lifting platform, called order picker, to access the shelves of a warehouse and collect some items. Such a nacelle includes a platform on which an operator usually stands. A nacelle must be provided for each operator, which is expensive and clutters the aisles of a warehouse.

Certaines nacelles de type voisin sont utilisées dans le domaine de la construction, par exemple pour monter un mur en parpaings, et il arrive que plusieurs opérateurs se tiennent sur une même plateforme. Dans ce cas, lorsqu'un des opérateurs doit descendre au sol, par exemple pour récupérer une quantité de mortier en vue de la pose de parpaings supplémentaires, tous les opérateurs doivent cesser de travailler en hauteur.Some nacelles of similar type are used in the field of construction, for example to mount a wall breeze blocks, and it happens that several operators stand on the same platform. In this case, when one of the operators must descend to the ground, for example to recover a quantity of mortar for the installation of additional blocks, all operators must stop working at height.

Il par ailleurs connu de FR-A-2 836 680 d'équiper une nacelle élévatrice d'une plateforme principale et de plateformes secondaires reliées à cette plateforme principale par des structures élévatrices. Une telle nacelle est adaptée à la pose de bardages. Elle ne permet toutefois pas à un opérateur présent sur une plateforme secondaire de pouvoir travailler indépendamment du ou des opérateurs présents sur la plateforme principale, en particulier de revenir temporairement au sol.He also known from FR-A-2,836,680 equipping a lifting platform with a main platform and secondary platforms connected to this main platform by lifting structures. Such a nacelle is suitable for cladding. However, it does not allow an operator present on a secondary platform to work independently of the operator or operators present on the main platform, in particular to return temporarily to the ground.

Il est par ailleurs connu de GB-A-579 219 de prévoir deux plateformes mobiles verticalement par rapport au châssis d'une nacelle sur roues dépourvue de moyens de motorisation. Cette nacelle ne permet pas à deux personnes de travailler en parallèle en accédant à une zone de chargement.It is also known from GB-A-579 219 to provide two mobile platforms vertically relative to the chassis of a nacelle on wheels devoid of motorization means. This pod does not allow two people to work in parallel by accessing a loading area.

C'est à ces inconvénients qu'entend plus particulièrement remédier l'invention en proposant une nouvelle nacelle élévatrice qui offre une souplesse d'utilisation améliorée par rapport aux matériels connus.It is these drawbacks that the invention intends to remedy more particularly by proposing a new aerial platform which offers improved flexibility of use compared to known equipment.

A cet effet, l'invention concerne une nacelle élévatrice pour préparation de commande ou travaux de construction comprenant un châssis équipé d'un ensemble de motorisation et de moyens de liaison au sol, ainsi qu'une première plateforme et des moyens d'élévation de cette première plateforme au-dessus du châssis, au moins une deuxième plateforme et des moyens d'élévation de la deuxième plateforme au-dessus du châssis, ces deuxièmes moyens d'élévation étant indépendants des premiers moyens d'élévation. Cette nacelle est caractérisée en ce qu'elle comprend, en outre, un plateau de chargement et des troisièmes moyens d'élévation du plateau de chargement au-dessus du châssis, ces troisièmes moyens d'élévation étant indépendants des premiers et deuxièmes moyens d'élévation.To this end, the invention relates to a lifting platform for control preparation or construction work comprising a chassis equipped with a set of motorization and ground connection means, and a first platform and elevation means of this first platform above the chassis, at least one second platform and elevation means of the second platform above the chassis, these second elevation means being independent of the first elevation means. This nacelle is characterized in that it comprises, in addition, a plateau loading and third means for lifting the loading platform above the frame, these third elevation means being independent of the first and second elevation means.

Grâce à l'invention, les deux plateformes peuvent être plus ou moins élevées au-dessus du châssis de façon indépendante, grâce à leurs moyens d'élévation respectifs, ce qui permet à un opérateur se tenant sur l'une de ces plateformes de se positionner en hauteur indépendamment de l'autre opérateur. En particulier, un opérateur peut revenir au sol sans que son collègue doive lui-même redescendre. L'indépendance des moyens d'élévation des plateformes permet à deux opérateurs se trouvant dans une allée d'un entrepôt d'accéder à des rayonnages situés à des hauteurs différentes. Cette indépendance permet également à des maçons de travailler à la construction d'un bâtiment à deux hauteurs différentes et de pouvoir redescendre au sol sans gêner le travail de leurs collègues. Le plateau de chargement permet à un opérateur travaillant en hauteur sur l'une ou l'autre des plateformes de stocker temporairement des objets à proximité de l'une ou l'autre des plateformes.Thanks to the invention, the two platforms can be higher or lower above the chassis independently, thanks to their respective elevation means, which allows an operator standing on one of these platforms to position in height independently of the other operator. In particular, an operator can return to the ground without his colleague having to go down again. The independence of platform elevation means allows two operators in an aisle of a warehouse to access shelves at different heights. This independence also allows masons to work on the construction of a building at two different heights and to be able to descend to the ground without hindering the work of their colleagues. The loading platform allows an operator working at height on one or other of the platforms to temporarily store objects near one or other of the platforms.

Selon des aspects avantageux mais non obligatoires de l'invention, une telle nacelle peut incorporer une ou plusieurs des caractéristiques suivantes :

  • Les premiers moyens d'élévation comprennent un premier mât télescopique et les deuxièmes moyens d'élévation comprennent un deuxième mât télescopique. Une telle structure des moyens d'élévation confère une bonne compacité à la nacelle de l'invention.
  • La course verticale d'élévation des troisièmes moyens d'élévation est supérieure à la course d'élévation des moyens d'élévation des première et deuxième plateformes.
  • Les troisièmes moyens d'élévation sont aptes à amener le plateau de chargement d'une configuration basse où celui-ci est à une hauteur minimale par rapport à la surface du sol à une configuration totalement déployée où le plateau de chargement est à la hauteur de barres supérieures de rambardes équipant les première et deuxième plateformes, elles-mêmes en configuration déployée.
  • Les troisièmes moyens d'élévation comprennent une structure à ciseaux. En variante, ils peuvent comprendre un troisième mât télescopique.
  • Le plateau de chargement est mobile en rotation, autour d'un axe perpendiculaire à la direction d'élévation du plateau de chargement au-dessus du châssis.
  • Chaque plateforme est équipée d'une platine de commande apte à piloter les troisièmes moyens d'élévation.
  • Le châssis est de forme allongée, les premiers moyens d'élévation sont montés sur le châssis au voisinage d'une première extrémité longitudinale de ce châssis alors que les deuxièmes moyens d'élévation sont montés sur le châssis au voisinage d'une deuxième extrémité longitudinale de ce châssis opposée à la première extrémité selon un axe longitudinal du châssis. Dans ce cas, le plateau de chargement est avantageusement disposé, le long de cet axe longitudinal, entre les premières et deuxièmes plateformes.
According to advantageous but non-mandatory aspects of the invention, such a nacelle can incorporate one or more of the following features:
  • The first elevation means comprise a first telescopic mast and the second elevation means comprise a second telescopic mast. Such a structure of the elevation means confers good compactness to the nacelle of the invention.
  • The vertical elevation stroke of the third elevation means is greater than the elevation stroke of the elevation means of the first and second platforms.
  • The third elevation means are adapted to bring the loading platform from a low configuration where it is at a minimum height relative to the ground surface to a fully deployed configuration where the loading platform is at the height of upper guardrail bars equipping the first and second platforms, themselves in deployed configuration.
  • The third elevation means comprise a scissors structure. Alternatively, they may comprise a third telescopic mast.
  • The loading tray is rotatable about an axis perpendicular to the elevation direction of the loading tray above the frame.
  • Each platform is equipped with a control plate able to control the third elevation means.
  • The frame is of elongated shape, the first elevation means are mounted on the frame in the vicinity of a first longitudinal end of this frame while the second elevation means are mounted on the frame in the vicinity of a second longitudinal end of the frame opposite the first end along a longitudinal axis of the frame. In this case, the loading plate is advantageously disposed along said longitudinal axis between the first and second platforms.

L'invention concerne également l'utilisation d'une nacelle élévatrice telle que mentionnée ci-dessus, pour le chargement ou le déchargement de rayonnages de stockage dans un entrepôt.The invention also relates to the use of a lifting platform as mentioned above, for loading or unloading storage racks in a warehouse.

L'invention concerne enfin l'utilisation d'une nacelle élévatrice telle que mentionnée ci-dessus, pour la construction d'un bâtiment.The invention finally relates to the use of a lifting platform as mentioned above, for the construction of a building.

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

  • la figure 1 est une vue en perspective d'une nacelle élévatrice conforme à l'invention dans une première configuration d'utilisation,

The invention will be better understood and other advantages thereof will appear more clearly in the light of the following description of an embodiment of a lifting platform according to its principle, given solely by way of example and with reference to the accompanying drawings in which:
  • the figure 1 is a perspective view of an aerial platform according to the invention in a first configuration of use,
  • the figure 2 is a front view of the nacelle of the figure 1 ,
  • the figure 3 is a perspective view on a smaller scale of the nacelle figures 1 and 2 in a second configuration of use,
  • the figure 4 is a perspective view similar to the figure 3 of the nacelle Figures 1 to 3 in a third configuration of use,

La nacelle 2 représentée aux figures 2 à 7 est destinée à être utilisée au sein d'un entrepôt pour la préparation de commandes. Elle comprend un châssis 4 reposant sur la surface du sol S par quatre roues, dont deux sont visibles avec la référence 6. Un ensemble de motorisation 8 est intégré au châssis 2 et permet de déplacer la nacelle 2 sur la surface du sol S.The nacelle 2 shown in Figures 2 to 7 is intended to be used within a warehouse for the preparation of orders. It comprises a chassis 4 resting on the surface of the ground S by four wheels, two of which are visible with the reference 6. An engine assembly 8 is integrated in the chassis 2 and allows the platform 2 to be moved on the surface of the ground S.

Le châssis 4 est de forme allongée et l'on note X4 l'axe longitudinal central de ce châssis. Le châssis 4 comprend deux extrémités longitudinales 4A et 4B qui sont opposées selon l'axe X4 et qui constituent respectivement les extrémités avant et arrière du châssis 4. En effet, le châssis 4 et les roues 6 sont configurés de telle sorte que le châssis se déplace sur la surface du sol S avec son axe X4 tangent à sa trajectoire.The frame 4 is elongated and X 4 is the central longitudinal axis of this frame. The chassis 4 comprises two longitudinal ends 4A and 4B which are opposite along the axis X 4 and which respectively constitute the front and rear ends of chassis 4. Indeed, the frame 4 and the wheels 6 are configured so that the frame moves on the surface of the ground S with its axis X 4 tangential to its trajectory.

Un premier mât télescopique 10 est monté sur le châssis 4 à proximité de l'extrémité 4A et s'étend le long d'un axe Z10 qui est perpendiculaire à l'axe X4 et vertical lorsque la nacelle 2 repose sur une surface S plane et horizontale. Le mât 10 est formé de trois segments 101, 102 et 103 pouvant coulisser les uns par rapport aux autres et dont le positionnement relatif est contrôlé par des vérins non représentés. Le segment 10, est fixé sur le châssis 4, alors que le segment 102 est monté avec possibilité de coulissement sur le segment 101 et que le segment 103 est monté avec possibilité de coulissement sur le segment 102.A first telescopic mast 10 is mounted on the frame 4 near the end 4A and extends along an axis Z 10 which is perpendicular to the axis X 4 and vertical when the platform 2 rests on a surface S flat and horizontal. The mast 10 is formed of three segments 10 1 , 10 2 and 10 3 slidable relative to each other and whose relative positioning is controlled by cylinders not shown. The segment 10, is fixed on the frame 4, while the segment 2 2 is mounted with the possibility of sliding on the segment 10 1 and the segment 3 3 is mounted with the possibility of sliding on the segment 10 2 .

Une plateforme 12 est montée sur le segment 102. Cette plateforme comprend une plaque de base 121 formant plancher et une rambarde 122 définissant un volume de sécurité pour un operateur.A platform 12 is mounted on the segment 10 2 . This platform comprises a base plate 12 1 forming a floor and a rail 12 2 defining a security volume for an operator.

Un deuxième mât télescopique 20 est monté sur le châssis 4 à proximité de l'extrémité 4B. Le mât 20 est formé de trois segments 201, 202 et 203 coulissant les uns par rapport aux autres selon un axe Z20 parallèle à l'axe Z10. Une plateforme 22 est montée sur le segment 203 et comprend une plaque de base 221 et une rambarde 222.A second telescopic mast 20 is mounted on the frame 4 near the end 4B. The mast 20 comprises three segments 20 January, 20 2 and 20 3 the slide relative to each other along a Z axis 20 parallel to the Z axis 10. A platform 22 is mounted on the segment 3 and comprises a base plate 22 1 and a rail 22 2 .

Les mâts 10 et 20 sont indépendants l'un de l'autre, en ce sens que chacun d'entre eux permet d'élever la nacelle 12 ou 22 qu'il supporte au-dessus du châssis 4, indépendamment de l'action de l'autre mât, donc indépendamment de la position de l'autre nacelle.The masts 10 and 20 are independent of each other, in the sense that each of them makes it possible to raise the platform 12 or 22 that it supports above the chassis 4, independently of the action of the other mast, so regardless of the position of the other nacelle.

Une platine de commande 14 est disposée dans le volume délimité par la rambarde 122 et permet à un opérateur se trouvant sur la plaque 12, de commander la position en hauteur de la plateforme 12. De la même façon, une platine de commande 24 est accessible pour un opérateur se trouvant sur la plateforme 22 et permet de commander son déplacement en hauteur.A control plate 14 is disposed in the volume delimited by the guardrail 12 2 and allows an operator on the plate 12 to control the height position of the platform 12. In the same way, a control plate 24 is accessible for an operator on the platform 22 and allows to control its movement height.

On note H1 la hauteur de la plateforme 12 par rapport au sol. On note H2 la hauteur de la plateforme 22 par rapport au sol. Dans la configuration des figures 1 et 2, les hauteurs H1 et H2 sont minimales.H 1 is the height of the platform 12 relative to the ground. H 2 is the height of the platform 22 relative to the ground. In the configuration of figures 1 and 2 , the heights H 1 and H 2 are minimum.

Comme il ressort de la figure 3, il est possible d'augmenter la hauteur H1 jusqu'à une valeur maximale permettant à un opérateur se trouvant sur la plateforme 12 de travailler en hauteur, alors qu'un autre opérateur se trouvant sur la plateforme 22 peut travailler au voisinage de la surface du sol, voire monter sur la plateforme 22 ou en descendre. Dans cette configuration, la hauteur H2 est minimale.As is apparent from the figure 3 it is possible to increase the height H 1 to a maximum value allowing an operator on the platform 12 to work at height, while another operator on the platform 22 can work in the vicinity of the surface of the ground, or even mount on the platform 22 or down. In this configuration, the height H 2 is minimal.

La hauteur H1 peut être réglée à une valeur intermédiaire entre la valeur minimale représentée aux figures 1 et 2 et la valeur maximale représentée à la figure 3.The height H 1 can be set to an intermediate value between the minimum value represented at figures 1 and 2 and the maximum value represented in figure 3 .

Une structure à ciseaux 30 intégrant un vérin 31 est installée sur le châssis 4, axialement entre les mâts 10 et 20, c'est-à-dire entre les extrémités 4A et 4B le long de l'axe X4. Cette structure à ciseaux 30 supporte un plateau de chargement 32 et permet de faire varier sa hauteur H3 par rapport à la surface du sol, entre une valeur minimale correspondante à la configuration des figures 1 et 2 et une valeur maximale correspondant à la configuration de la figure 4. Dans cette configuration, le plateau de chargement 32 est disposé au voisinage de la nacelle 12, ce qui permet à un opérateur d'y stocker temporairement des objets lorsqu'il travaille en hauteur.A scissors structure 30 incorporating a jack 31 is installed on the frame 4, axially between the poles 10 and 20, that is to say between the ends 4A and 4B along the axis X 4 . This scissors structure 30 supports a loading platform 32 and makes it possible to vary its height H 3 relative to the ground surface, between a minimum value corresponding to the configuration of the figures 1 and 2 and a maximum value corresponding to the configuration of the figure 4 . In this configuration, the loading platform 32 is disposed in the vicinity of the nacelle 12, which allows an operator to temporarily store objects when working at height.

Le vérin 31 est actionnable pour positionner le plateau 32 dans toute position intermédiaire entre celles représentées respectivement aux figures 1 et 4.The jack 31 is operable to position the plate 32 in any intermediate position between those represented respectively in FIGS. figures 1 and 4 .

Le fonctionnement de la structure à ciseaux peut être piloté par chacune des unités 14 et 24 qui commandent le vérin 31.The operation of the scissors structure can be controlled by each of the units 14 and 24 which control the jack 31.

Dans la configuration des figures 1 et 2, la hauteur H3 du plateau de chargement 32 par rapport à la surface du sol est minimale. En particulier, la surface supérieure du plateau de chargement 32 est en dessous des barres supérieures 123 et 223 des rambardes 122 et 222.In the configuration of figures 1 and 2 , the height H 3 of the loading platform 32 relative to the ground surface is minimal. In particular, the upper surface of the loading platform 32 is below the upper bars 12 3 and 22 3 of the railings 12 2 and 22 2 .

La course verticale d'élévation de la structure à ciseaux 30 a lieu selon un axe Z30 parallèle aux axes Z10 et Z20 et est légèrement supérieure, de quelques dizaines de centimètres, à la course d'élévation des mâts 10 et 20 de telle sorte que, en configuration totalement déployée représentée aux figures 4 et 5, le plateau de chargement 32 est à la hauteur de la barre supérieure 123 ou 223 des rambardes 122 et 222. Ceci facilite les opérations de mise en place d'objets ou de retrait sur le plateau 32, pour un opérateur se trouvant sur l'une des plateformes 12 et 22.The vertical stroke of elevation of the scissor structure 30 takes place along an axis Z 30 parallel to the axes Z 10 and Z 20 and is slightly greater, by a few tens of centimeters, to the elevation stroke of the poles 10 and 20 of such that, in a fully deployed configuration represented in figures 4 and 5 the loading platform 32 is at the height of the upper bar 12 3 or 22 3 of the railings 12 2 and 22 2 . This facilitates the operations of placing objects or withdrawal on the plate 32, for an operator on one of the platforms 12 and 22.

Dans la configuration de la figure 4, le plateau 32 est représenté en position haute permettant à un opérateur se trouvant sur la plateforme 12 également en position haute d'accéder facilement à des objets sur le plateau 32, alors que la nacelle 22 est en position basse.In the configuration of the figure 4 , the plate 32 is shown in the high position allowing an operator on the platform 12 also in the high position to easily access objects on the plate 32, while the nacelle 22 is in the low position.

Dans la configuration des figures 5 et 6, les deux nacelles 12 et 22 sont en position haute, les hauteurs H1 et H2 étant maximales, de même que la hauteur H3 du plateau de chargement par rapport au sol.In the configuration of figures 5 and 6 the two pods 12 and 22 are in the high position, the heights H 1 and H 2 being maximum, as well as the height H 3 of the loading platform relative to the ground.

Comme il ressort plus particulièrement de la figure 7, le plateau 32 est articulé par rapport à la structure à ciseaux 30 autour d'un axe X7 parallèle à l'axe X4 et perpendiculaire aux axes Z10 et Z20- Ceci permet de faire basculer le plateau 32 dans le sens de la flèche F1 à la figure 7. Ceci facilite les opérations de déchargement du plateau 32 lorsque les deux opérateurs sont revenus au sol, à partir de la configuration des figures 5 et 6.As is clear from the figure 7 , the plate 32 is articulated with respect to the scissors structure 30 about an axis X 7 parallel to the axis X 4 and perpendicular to the axes Z 10 and Z 20 - This makes it possible to tilt the plate 32 in the direction of the arrow F 1 to the figure 7 . This facilitates the unloading operations of the plate 32 when the two operators have returned to the ground, from the configuration of the figures 5 and 6 .

Comme la structure à ciseaux 30 est indépendante des mâts 10 et 20, la hauteur du plateau 32 par rapport au sol peut être ajustée indépendamment de la hauteur des plateformes 12 et 22. Cette hauteur peut être commandée par chacune des platines 14 et 24, ou par l'une d'entre elles si l'on souhaite donner priorité à un opérateur se trouvant sur l'une des plateformes 12 ou 22.As the scissors structure 30 is independent of the masts 10 and 20, the height of the plate 32 relative to the ground can be adjusted independently of the height of the platforms 12 and 22. This height can be controlled by each of the plates 14 and 24, or by one of them if it is desired to give priority to an operator on one of the platforms 12 or 22.

Ainsi, un opérateur peut se trouver sur chacune des plateformes 12 et 22 alors qu'un autre opérateur travaille au sol, pour charger et/ou décharger le plateau 32 avant ou après que celui-ci ait été chargé en objets par les opérateurs se trouvant sur les plateformes.Thus, an operator can be on each of the platforms 12 and 22 while another operator is working on the ground, to load and / or unload the tray 32 before or after it has been loaded into objects by operators located on platforms.

La structure télescopique des mâts 10 et 20 permet un encombrement au sol relativement faible de la nacelle 2, notamment en comparaison au cas où les plateformes 12 et 22 seraient supportées par des bras articulés qui supporteraient les plateformes en porte-à-faux par rapport au châssis 4.The telescopic structure of the masts 10 and 20 allows a relatively small footprint of the nacelle 2, particularly in comparison to the case where the platforms 12 and 22 would be supported by articulated arms that support the platforms cantilevered with respect to the chassis 4.

La nacelle 2 s'avère particulièrement utile pour des opérations de chargement ou de déchargement de rayonnages de stockage au sein d'un entrepôt, dans la mesure où deux opérateurs peuvent travailler, à des hauteurs différentes, dans une même allée, entre deux rangées de rayonnages. Chaque opérateur peut accéder à des rayonnages situés à des hauteurs différentes ou revenir à la surface du sol, par exemple pour décharger le plateau 32, indépendamment de l'autre opérateur.The nacelle 2 is particularly useful for loading or unloading storage racks within a warehouse, since two operators can work, at different heights, in the same aisle, between two rows of racks. shelves. Each operator can access shelves at different heights or return to the surface of the ground, for example to unload the tray 32, independently of the other operator.

La nacelle 2 peut également être utilisée dans le domaine de la construction de bâtiments, par exemple pour monter un mur en parpaings, chaque maçon pouvant prélever des parpaings disposés sur le plateau de chargement 32 et les poser sur un mur en cours de construction. Chaque maçon peut revenir à la surface du sol lorsqu'il doit effectuer d'autres opérations, sans gêner ou interrompre le travail des autres maçons.The nacelle 2 can also be used in the field of building construction, for example to mount a wall blocks, each mason can take breeze blocks arranged on the loading platform 32 and put them on a wall under construction. Each mason can return to the surface of the ground when he has to perform other operations, without hindering or interrupting the work of other masons.

Selon une variante non représentée de l'invention, la structure à ciseaux 30 peut être remplacée par un mât télescopique vertical comparable aux mâts 10 et 20.According to a variant not shown of the invention, the scissor structure 30 can be replaced by a vertical telescopic mast comparable to the masts 10 and 20.

L'invention a été représentée dans le cas où elle comprend deux plateformes sur chacune desquelles peut se tenir au moins un opérateur. En variante, une telle nacelle peut être équipée de plus de deux plateformes, par exemple trois plateformes, chacune de ces plateformes étant associée à des moyens d'élévation par rapport au châssis qui sont indépendants des moyens d'élévation des autres plateformes.The invention has been shown in the case where it comprises two platforms on each of which can be held at least one operator. In a variant, such a platform may be equipped with more than two platforms, for example three platforms, each of these platforms being associated with elevation means relative to the chassis which are independent of the elevation means of the other platforms.

A la place des roues 6, d'autres moyens de liaison au sol tels que des chenilles sont envisageables.Instead of the wheels 6, other ground connection means such as caterpillars are conceivable.
