Description

L'invention concerne une nacelle élévatrice.The invention relates to a lifting platform.

Les nacelles élévatrices, et plus généralement les plateformes élévatrices mobiles de personnel (PEMP), comprennent une plateforme montée sur des moyens d'élévation permettant de travailler en hauteur. Lors de la saison hivernale, des travaux peuvent être effectués en conditions de faible luminosité, ce qui implique l'utilisation d'éclairages.The lifting nacelles, and more generally the mobile lifting platforms for personnel (PEMP), comprise a platform mounted on lifting means making it possible to work at height. During the winter season, work can be carried out in low light conditions, which implies the use of lighting.

Il est connu, notamment de DE-A-29 24 820 , d'équiper une nacelle élévatrice avec un projecteur d'éclairage attachable sur le garde-corps de la plateforme pour éclairer avec une forte intensité la zone ou les objets sur lesquels le travail doit être effectué. Un tel projecteur, connu par exemple de JP-A-2012/158286 , est volumineux et est exposé aux chocs du fait de son montage sur le garde-corps. En outre, un tel projecteur ne permet pas un éclairage de confort, c'est-à-dire un éclairage permettant à la personne se trouvant sur la plateforme de correctement diriger les mouvements de la plateforme par rapport à son environnement et de distinguer l'intérieur de la plateforme elle-même et les objets qui peuvent y être entreposés, la plateforme elle-même restant maintenue dans la pénombre. CN 103626 087A décrit une lampe pouvant se déplacer dans plusieurs directions. Le document ne précise pas que la lumière éclaire spécifiquement l'accès à la plate-forme. Si la lampe est placée dans une direction opposée à la plate-forme, l'accès à celle-ci n'est pas éclairé.It is known, in particular from DE-A-29 24 820 , to equip a lifting platform with an attachable lighting projector on the railing of the platform to illuminate with strong intensity the area or the objects on which the work must be carried out. Such a projector, known for example from JP-A-2012/158286 , is bulky and is exposed to shocks due to its mounting on the railing. In addition, such a projector does not allow comfort lighting, that is to say lighting allowing the person on the platform to correctly direct the movements of the platform relative to its environment and to distinguish the inside the platform itself and the objects that can be stored there, the platform itself remaining kept in the dark. CN 103626 087A describes a lamp which can move in several directions. The document does not state that the light specifically illuminates access to the platform. If the lamp is placed in a direction opposite to the platform, access to it is not illuminated.

C'est à ces inconvénients qu'entend remédier l'invention en proposant une nouvelle nacelle élévatrice, dont l'accès et le confort de travail en conditions de faible luminosité est amélioré.It is to these drawbacks that the invention intends to remedy by proposing a new lifting platform, whose access and working comfort in low light conditions is improved.

  • la figure 2 est une vue en perspective d'une plateforme de la nacelle élévatrice de la figure 1
  • la figure 3 est une vue à plus grande échelle du détail III à la figure 2 représentant un pupitre de commande de la plateforme de la figure 2 ;
  • la figure 4 est une vue de côté de la plateforme de la figure 2.
The invention will be better understood and other advantages thereof will appear more clearly in the light of the description which follows, of an aerial lift conforming to its principle, given by way of nonlimiting example with reference to the drawings annexed, in which:
  • the figure 1 is a perspective view of a lifting platform according to the invention;
  • the figure 2 is a perspective view of a platform of the lifting platform of the figure 1
  • the figure 3 is an enlarged view of detail III to the figure 2 representing a console of the platform of the figure 2 ;
  • the figure 4 is a side view of the platform of the figure 2 .

Sur la figure 1 est représentée une nacelle élévatrice 1 comprenant une partie basse incluant un châssis 3 équipé d'organes de liaison au sol, tels que des roues ou des chenilles. La partie basse comprend également une tourelle 5 mobile en rotation par rapport au châssis 3 selon un axe perpendiculaire aux axes de rotation des roues, une structure élévatrice 7 et une plateforme 9, représentée aux figures 2, 3 et 4, soutenue par la structure élévatrice 7. La plateforme 9 comprend un plancher grillagé 90 entouré d'un garde-corps 92.On the figure 1 depicted is an elevating nacelle 1 comprising a lower part including a chassis 3 equipped with ground connection members, such as wheels or tracks. The lower part also comprises a turret 5 movable in rotation relative to the chassis 3 along an axis perpendicular to the axes of rotation of the wheels, a lifting structure 7 and a platform 9, shown in figures 2 , 3 and 4 , supported by the lifting structure 7. The platform 9 comprises a mesh floor 90 surrounded by a railing 92.

Le garde-corps 92 comprend un tube supérieur parallèle au plancher grillagé 90 et formé par quatre sections incluant une section arrière 92a, de grande longueur et située du côté opposé au raccordement de la structure élévatrice 7 sur la plateforme 9. Une zone d'accès 93 est préférentiellement ménagée du côté de la section arrière 92a. Le tube supérieur inclut également une section avant 92b opposée à la section arrière 92a, et orientée du côté de la structure élévatrice 7. Entre les sections 92a et 92b, deux sections latérales 92c et 92d complètent le tube supérieur. En variante non représentée, la zone d'accès 93 peut être ménagée du côté d'une des sections latérales 92c et 92d.The railing 92 comprises an upper tube parallel to the mesh floor 90 and formed by four sections including a rear section 92a, of great length and located on the side opposite to the connection of the lifting structure 7 on the platform 9. An access area 93 is preferably arranged on the side of the rear section 92a. The upper tube also includes a front section 92b opposite the rear section 92a, and oriented towards the side of the lifting structure 7. Between the sections 92a and 92b, two lateral sections 92c and 92d complete the upper tube. In a variant not shown, the access area 93 can be provided on the side of one of the lateral sections 92c and 92d.

En configuration d'utilisation de la nacelle 1, le ou les opérateurs utilisent une zone de travail située du côté des sections 92a, 92c et 92d. Ces parties du garde-corps 92 sont exposées aux chocs et aux salissures.In configuration of use of nacelle 1, the operator (s) use a work area located on the side of sections 92a, 92c and 92d. These parts of the railing 92 are exposed to shocks and dirt.

La zone d'accès 93 est formée par une partie mobile 92f d'un barreau horizontal 92e du garde-corps 92, cette partie mobile 92f étant adaptée pour être soulevée et permettre l'entrée d'une personne sur la plateforme 9. En variante non représentée, la zone d'accès 93 peut être formée par un portillon articulé par rapport au garde-corps 92.The access area 93 is formed by a mobile part 92f of a horizontal bar 92e of the railing 92, this mobile part 92f being adapted to be lifted and allow the entry of a person onto the platform 9. As a variant not shown, the access area 93 may be formed by a door articulated with respect to the railing 92.

La plateforme 9 est équipée d'un pupitre de commande 94 permettant de contrôler la nacelle élévatrice 1, notamment les mouvements de la plateforme 9 par rapport au châssis 3, et qui monté au centre de la section avant 92b du garde-corps 92.The platform 9 is equipped with a control console 94 making it possible to control the lifting platform 1, in particular the movements of the platform 9 relative to the chassis 3, and which mounted in the center of the front section 92b of the railing 92.

Les termes « arrière » et « avant » sont utilisés en référence au fait que lorsqu'un opérateur se trouve devant le pupitre de commande 94, la section 92d du garde-corps 92 se trouve derrière lui.The terms “rear” and “front” are used with reference to the fact that when an operator is in front of the control console 94, the section 92d of the railing 92 is behind him.

Conformément à l'invention, la plateforme 9 est équipée d'un système d'éclairage autre que des phares de conduite, adapté pour éclairer au moins en partie un espace intérieur E de la plateforme 9, c'est-à-dire le volume délimité par le garde-corps, incluant au moins une partie de la zone d'accès 93, de manière qu'un opérateur se trouvant en dehors de la plateforme 9 puisse repérer celle-ci dans l'obscurité et y accéder sans danger, et pour faciliter le travail des opérateurs sur la plateforme en conditions de basse luminosité.According to the invention, the platform 9 is equipped with a lighting system other than driving lights, adapted to light at least partially an interior space E of the platform 9, that is to say the volume bounded by the railing, including at least part of the access area 93, so that an operator outside the platform 9 can spot it in the dark and access it safely, and to facilitate the work of operators on the platform in low light conditions.

Le système d'éclairage de la plateforme 9 comprend à cet effet un premier dispositif d'éclairage comprenant au moins une source de lumière, prévue sur une partie de garde-corps 92 éloignée de la zone de travail, et dirigée vers l'intérieur de la plateforme 9. L'intensité d'éclairement fournie par le premier système d'éclairage est moyenne ou faible, c'est-à-dire de préférence comprise entre un et cinq lux à deux mètres.The lighting system of the platform 9 for this purpose comprises a first lighting device comprising at least one light source, provided on a railing portion 92 remote from the work area, and directed towards the interior of the platform 9. The intensity of illumination provided by the first lighting system is medium or low, that is to say preferably between one and five lux at two meters.

Dans l'exemple représenté, le premier dispositif d'éclairage comprend deux sources de lumière 100 et 101 telles que par exemple des diodes électroluminescentes (ci-après LED) fixées sur le pupitre de commande 94 et qui éclairent la zone intérieure E de la plateforme 9, la zone d'accès 93 de la plateforme 9 en formant des faisceaux lumineux F1 et F2. Sur la figure 4, les faisceaux F1 et F2 sont confondus. Les faisceaux F1 et F2 sont dirigés selon une direction horizontale, en direction d'un côté extérieur de la nacelle élévatrice 1, c'est-à-dire en direction de la section 92a. Avantageusement, les sources de lumière 100 et 101 sont adaptées pour que les faisceaux F1 et F2 éclairent l'intégralité de la section 92a.In the example shown, the first lighting device comprises two light sources 100 and 101 such as for example light-emitting diodes (hereinafter LED) fixed on the control console 94 and which light the interior area E of the platform 9, the access area 93 of the platform 9 by forming light beams F1 and F2. On the figure 4 , the beams F1 and F2 are confused. The beams F1 and F2 are directed in a horizontal direction, in the direction of an outer side of the lifting platform 1, that is to say in the direction of section 92a. Advantageously, the light sources 100 and 101 are adapted so that the beams F1 and F2 illuminate the entire section 92a.

Le fait que les sources de lumière 100 et 101 soient prévues sur le pupitre de commande 94 permet d'éviter leur exposition à des chocs éventuels, car elles ne se trouvent pas sur les côtés du garde-corps 92 correspondant aux sections 92a, 92c et 92d, là où les chocs avec un élément extérieur sont susceptibles de survenir.The fact that the light sources 100 and 101 are provided on the control console 94 makes it possible to avoid their exposure to possible shocks, since they are not located on the sides of the railing 92 corresponding to sections 92a, 92c and 92d, where impacts with an external element are likely to occur.

L'intégration des sources de lumière 100 et 101 sur le pupitre de commande 94 permet de minimiser la longueur de câbles nécessaire à leur alimentation électrique.The integration of the light sources 100 and 101 on the control console 94 makes it possible to minimize the length of cables necessary for their electrical supply.

Les sources de lumière 100 et 101 sont fixées chacune sous un rebord 941 du pupitre de commande 94, afin d'être protégées des chocs venant par le dessus. La plateforme 9 comprend en outre des structures mécaniques de protection des sources de lumière 100 et 101, formées par exemple par des barres métalliques 106 et 107 disposées autour du pupitre de commande 94 et pouvant être reliées au garde-corps 92.The light sources 100 and 101 are each fixed under a flange 941 of the control desk 94, in order to be protected from impacts coming from above. The platform 9 also comprises mechanical structures for protecting light sources 100 and 101, formed for example by metal bars 106 and 107 arranged around the control desk 94 and which can be connected to the railing 92.

Le premier dispositif d'éclairage éclaire également l'environnement immédiat de la plateforme 9 de manière qu'un opérateur présent sur la plateforme 9 soit en mesure d'effectuer des déplacements de la plateforme 9 par rapport au châssis 3 et à la tourelle 5 dans un environnement non éclairé. En d'autres termes, le système d'éclairage est adapté pour éclairer à une intensité moyenne ou faible les abords de la plateforme 9 de manière à repérer un éventuel obstacle suffisamment tôt. Les faisceaux F1 et F2 permettent d'éclairer, par exemple, un mur vertical M se trouvant dans l'environnement immédiat de la plateforme 9, de manière que l'opérateur contrôlant le déplacement de la plateforme 9 par rapport au châssis 3 puisse s'assurer que la plateforme 9 ne heurte pas le mur M dans l'obscurité.The first lighting device also illuminates the immediate environment of the platform 9 so that an operator present on the platform 9 is able to move the platform 9 relative to the chassis 3 and to the turret 5 in an unlit environment. In other words, the lighting system is adapted to light the surroundings of the platform 9 at a medium or low intensity so as to identify a possible obstacle sufficiently early. The beams F1 and F2 make it possible to illuminate, for example, a vertical wall M located in the immediate environment of the platform 9, so that the operator controlling the movement of the platform 9 relative to the chassis 3 can ensure that the platform 9 does not strike the wall M in the dark.

La vitesse maximale de déplacement de la plateforme 9 par rapport au sol est généralement limitée à 0,7 mètres par seconde lorsque la structure élévatrice 7 est dépliée. Les faisceaux lumineux F1 et F2 sont adaptés pour éclairer l'environnement immédiat de la plateforme 9 jusqu'à une distance déterminée par rapport à la plateforme 9, par exemple deux mètres. Cette distance et une intensité d'éclairement comprise entre 1 et 5 lux à deux mètres sont suffisantes pour immobiliser la plateforme 9 avant un obstacle. Les mouvements de levage de la plateforme s'effectuent à une vitesse maximale de 0,4 m/s, et la rotation de la tourelle 5 se fait à une vitesse maximale de 0,7 km/h. Un tel éclairage se distingue d'un projecteur de travail, qui éclaire une zone précise avec une intensité forte, c'est-à-dire au moins égale à vingt lux à deux mètres permettant à un opérateur d'effectuer une tache précise, ou d'un phare de conduite, adapté pour éclairer l'environnement situé sur le sol en avant du châssis d'un véhicule lorsqu'il se déplace, et non l'environnement immédiat du véhicule, qui reste dans l'obscurité. Le premier dispositif d'éclairage n'est pas utilisé en configuration de déplacement par rapport au sol avec la structure élévatrice 7 repliée, car la vitesse est plus importante et nécessite des phares de conduite.The maximum speed of movement of the platform 9 relative to the ground is generally limited to 0.7 meters per second when the lifting structure 7 is unfolded. The light beams F1 and F2 are adapted to illuminate the immediate environment of the platform 9 up to a determined distance from the platform 9, for example two meters. This distance and an intensity of illumination between 1 and 5 lux at two meters are sufficient to immobilize the platform 9 before an obstacle. The lifting movements of the platform take place at a maximum speed of 0.4 m / s, and the rotation of the turret 5 takes place at a maximum speed of 0.7 km / h. Such lighting is distinguished from a work spotlight, which illuminates a precise area with a strong intensity, that is to say at least equal to twenty lux at two meters allowing an operator to perform a precise task, or a driving light, adapted to illuminate the environment located on the ground in front of the chassis of a vehicle when it is moving, and not the immediate environment of the vehicle, which remains in the dark. The first lighting device is not used in the displacement configuration relative to the ground with the lifting structure 7 folded, because the speed is greater and requires driving lights.

Le système d'éclairage de la plateforme 9 comprend également un deuxième dispositif d'éclairage adapté pour éclairer le pupitre de commande 94. Le pupitre de commande 94 regroupe des voyants lumineux, des interrupteurs et un ou plusieurs organes de commande manuelle 94a, 94b et 94c permettant le contrôle des fonctionnalités de la nacelle élévatrice 1. Le pupitre de commande 94 doit être utilisable par un opérateur se trouvant dans la plateforme 9 en cas de luminosité faible. Le deuxième dispositif d'éclairage comprend à cet effet au moins une source de lumière fixée sur le pupitre de commande 94. Dans l'exemple représenté, le deuxième dispositif d'éclairage comprend deux sources de lumière 104 et 105 fixées sur le pupitre de commande 94, de part et d'autre d'un ilot central 95.The lighting system of the platform 9 also includes a second lighting device adapted to illuminate the control console 94. The control console 94 includes indicator lights, switches and one or more manual control members 94a, 94b and 94c allowing the control of the functionalities of the lifting platform 1. The control desk 94 must be usable by an operator located in the platform 9 in low light conditions. The second lighting device for this purpose comprises at least one light source fixed on the control console 94. In the example shown, the second lighting device comprises two light sources 104 and 105 fixed on the control console 94, on either side of a central island 95.

Le pupitre de commande 94 comprend avantageusement un capot de protection 96 rabattable permettant de protéger les organes de commande et les autres composants en dehors des plages d'utilisation de la nacelle élévatrice 1. Le capot 96 est représenté ouvert sur les figures 1, 2 et 3. Une face interne du capot rabattable 96 comprend des surfaces réfléchissantes 97 situées en regard des sources de lumière 104 et 105 de manière que les surfaces réfléchissantes 97 diffusent la lumière produite par les sources de lumière 104 et 105 sur le pupitre de commande 94, comme cela est représenté par les flux lumineux F3 et F4 à la figure 3, ce qui permet à l'opérateur de distinguer le pupitre de commande 94 de façon suffisamment claire pour consulter l'état de la machine et utiliser les interrupteurs et organes de commande manuelle en configuration de luminosité faible.The control desk 94 advantageously comprises a folding protective cover 96 making it possible to protect the control members and the other components outside the ranges of use of the lifting platform 1. The cover 96 is shown open to figures 1 , 2 and 3 . An internal face of the folding cover 96 includes reflecting surfaces 97 located opposite the light sources 104 and 105 so that the reflecting surfaces 97 diffuse the light produced by the light sources 104 and 105 on the control console 94, like this is represented by the luminous fluxes F3 and F4 at the figure 3 , which allows the operator to distinguish the control panel 94 clearly enough to consult the status of the machine and use the switches and manual controls in low light configuration.

Le système d'éclairage comprend également un troisième dispositif d'éclairage adapté pour éclairer l'environnement immédiat de la plateforme 9 située sous la plateforme 9. Ce troisième dispositif d'éclairage comprend avantageusement une source de lumière 103, telle que par exemple une LED, qui projette un faisceau lumineux F5 dirigé vers le bas et permettant d'éclairer un obstacle situé sous la plateforme 9, par exemple un toit T d'un bâtiment au voisinage duquel la nacelle élévatrice 14 est utilisée. La source de lumière 103 est de préférence fixée sous le plancher 90.The lighting system also comprises a third lighting device suitable for lighting the immediate environment of the platform 9 located under the platform 9. This third lighting device advantageously comprises a light source 103, such as for example an LED , which projects a light beam F5 directed downwards and making it possible to illuminate an obstacle located under the platform 9, for example a roof T of a building in the vicinity of which the lifting platform 14 is used. The light source 103 is preferably fixed under the floor 90.

Les trois dispositifs d'éclairage décrits ci-dessus peuvent être équipés, en remplacement des LED, d'autres types de sources de lumière, et comprendre des nombres différents de sources de lumière tout en remplissant les mêmes fonctions.The three lighting devices described above can be equipped, in place of LEDs, with other types of light sources, and include different numbers of light sources while fulfilling the same functions.

Le système d'éclairage de la plateforme 9 peut incorporer uniquement le premier dispositif d'éclairage ou bien uniquement le deuxième dispositif d'éclairage.The lighting system of the platform 9 can incorporate only the first lighting device or else only the second lighting device.

De façon optionnelle, la partie basse est également équipé d'un pupitre de commande 50, prévu par exemple sur un côté de la tourelle 5, accessible par une personne se trouvant au sol, et permettant notamment la mise en route de la nacelle élévatrice 1, et le contrôle de certains mouvements de la plateforme 9 en cas d'urgence. Le pupitre de commande 50 est muni d'un dispositif d'éclairage 52, qui peut comprendre une ou plusieurs sources de lumière telles que des LED.Optionally, the lower part is also equipped with a control console 50, provided for example on one side of the turret 5, accessible by a person on the ground, and in particular allowing the starting of the lifting platform 1 , and the control of certain movements of platform 9 in the event of an emergency. The control console 50 is provided with a lighting device 52, which may include one or more light sources such as LEDs.

A partir du pupitre de commande 50, un opérateur peut décider de transférer le contrôle de la nacelle 1 vers le pupitre de commande 94 de la plateforme 9, ce qui va activer l'éclairage de la plateforme 9 de manière que l'opérateur puisse y accéder. En effet, pour les nacelles élévatrices dont la structure élévatrice 7 est d'une grande longueur, l'opérateur peut avoir à parcourir plusieurs mètres pour accéder à la plateforme 9. Dans un tel cas, l'éclairage d'une partie de la plateforme 9 permet à l'opérateur de se diriger facilement dans l'obscurité vers la plateforme 9, y repérer la zone d'accès 93 et y accéder.From the control console 50, an operator can decide to transfer control of the nacelle 1 to the control console 94 of the platform 9, which will activate the lighting of the platform 9 so that the operator can to access. Indeed, for the lifting nacelles whose lifting structure 7 is of great length, the operator may have to travel several meters to access the platform 9. In such a case, the lighting of part of the platform 9 allows the operator to easily navigate in the dark towards the platform 9, locate the access area 93 there and access it.

L'invention ne se limite pas à une nacelle élévatrice à tourelle et bras articulé telle que représentée dans cet exemple, et s'applique également à tous les types de nacelles élévatrices de personnel, notamment les structures élévatrices de type bras télescopique, ciseau et mât vertical et les nacelles montées sur un châssis de camion ou un châssis de remorque.The invention is not limited to a lifting platform with a turret and articulated arm as shown in this example, and also applies to all types of personnel lifting platforms, in particular lifting structures of the telescopic arm type, chisel and vertical mast and nacelles mounted on a truck chassis or a trailer chassis.

Une personne se trouvant sur la plateforme et devant diriger la manœuvre de la plateforme et de la nacelle élévatrice en hauteur ou par rapport au sol est capable de distinguer d'éventuels obstacles dans l'environnement proche de la nacelle.A person who is on the platform and who has to direct the maneuver of the platform and the lifting platform in height or above the ground is capable of distinguishing possible obstacles in the environment close to the platform.

Selon un mode de réalisation non représenté de l'invention, les premiers et deuxièmes dispositifs d'éclairage peuvent ne faire qu'un et constituer un unique dispositif d'éclairage adapté pour à la fois éclairer la zone d'accès à la plateforme, l'environnement extérieur et le pupitre de commande.According to an embodiment not shown of the invention, the first and second lighting devices can be one and constitute a single lighting device suitable for both illuminating the access area to the platform, l environment and the control console.

Les caractéristiques des modes de réalisation et variantes décrits ci-dessus peuvent être combinées pour former de nouveaux modes de réalisation de l'invention.The features of the embodiments and variants described above can be combined to form new embodiments of the invention.
