Description

Le domaine de l'invention est celui des ascenseurs. Plus précisément, l'invention concerne les équipements installés dans les gaines d'ascenseur pour assurer les déplacements de la cabine d'ascenseur.The field of the invention is that of lifts. More specifically, the invention relates to the equipment installed in the elevator shafts to ensure the movements of the elevator car.

On précise que l'on entend par ascenseurs non seulement les ascenseurs pour personnes mais également les monte-charges pour marchandises volumineuses.It is specified that the term "lifts" means not only lifts for persons but also lifts for bulky goods.

L'invention s'applique en particulier, mais non exclusivement, aux navires, notamment les navires pour passagers, les navires de charges, les navires militaires... Toutefois, la technique selon l'invention peut de façon similaire être appliquée aux bâtiments terrestres.The invention applies in particular, but not exclusively, to ships, in particular passenger ships, cargo ships, military vessels ... However, the technique according to the invention can similarly be applied to land vessels .

Un ascenseur est classiquement constitué par l'assemblage et le montage d'un certain nombre de parties constitutives dans la gaine de l'ascenseur. Les organes essentiels au fonctionnement de l'ascenseur sont :

  • la ou les cabines ;
  • les rails de guidage pour la ou les cabines ;
  • le ou les contrepoids ;
  • les rails de guidage pour le ou les contrepoids ;
  • la machinerie ;
  • les câbles de traction reliant la machinerie aux contrepoids et aux cabines ;
  • les goulottes de circulation de câbles électriques ;
  • ...
An elevator is conventionally constituted by the assembly and assembly of a number of constituent parts in the shaft of the elevator. The essential organs for the operation of the lift are:
  • the cabin or cabins;
  • guide rails for the one or more cabins;
  • the counterweight or counterweight;
  • guide rails for the counterweight or counterweights;
  • machinery;
  • traction cables connecting machinery to counterweights and cabins;
  • chutes for the circulation of electric cables;
  • ...

Généralement, les rails de guidage pour les cabines, les rails de guidage pour les contrepoids, les goulottes et les échelles sont regroupés sur l'ensemble des parois d'une gaine constituant l'enveloppe de l'ascenseur.Generally, the guide rails for the cabins, the guide rails for the counterweights, the chutes and the ladders are grouped together on all the walls of a sheath constituting the envelope of the elevator.

Actuellement, le montage des ascenseurs sur des navires est intégralement réalisé lors de la phase d'armement du navire : les différentes parties constitutives listées précédemment sont embarquées sous forme de pièces détachées et assemblées, le plus souvent par soudage, les unes aux autres et aux différents ponts du navire et parois de la gaine d'ascenseur.Currently, the assembly of lifts on ships is fully realized during the phase of arming the ship: the different component parts listed previously are shipped as spare parts and assembled, usually by welding, to each other and to the various decks of the ship and walls of the elevator shaft.

Sachant que les navires équipés d'ascenseurs ou de montes-charges comportent généralement entre trois et quinze ponts, on comprend que les opérations de montage d'un ascenseur dans un navire s'avèrent longues et fastidieuses.Knowing that ships equipped with elevators or lifts generally comprise between three and fifteen bridges, it is understood that the operations of mounting an elevator in a ship are long and tedious.

A titre indicatif, l'installation d'un ascenseur simple (une seule cabine) sur un navire comportant dix ponts représente un total d'environ 1 200 heures de main-d'oeuvre.As an indication, the installation of a single elevator (one cabin) on a vessel with ten decks represents a total of about 1,200 man-hours.

En outre, une telle installation d'ascenseur implique un niveau de risques non négligeable du fait des conditions de travail dans la gaine d'ascenseur (travail en hauteur, espace restreint, projection de soudure, ...).In addition, such a lift installation involves a significant level of risk because of the working conditions in the elevator shaft (working at height, restricted space, welding projection, etc.).

Or, la multiplication des opérations d'installation et la durée importante nécessaires à leur réalisation tend à confirmer, voire augmenter ce niveau de risques.However, the multiplication of the installation operations and the long duration necessary for their realization tends to confirm or even increase this level of risk.

L'invention a notamment pour objectif de pallier les inconvénients de l'art antérieur.The invention particularly aims to overcome the disadvantages of the prior art.

Plus précisément, l'invention a pour objectif de proposer une nouvelle technique d'installation d'ascenseur qui permette de réduire notablement les temps d'installationMore specifically, the invention aims to propose a new elevator installation technique that significantly reduces installation time

L'invention a également pour objectif de fournir une telle technique qui puisse s'intégrer aisément dans un navire. En ce sens, l'invention a aussi pour objectif de fournir une telle technique qui n'entraîne pas de surcharge ou de perte d'espace.The invention also aims to provide such a technique that can easily integrate into a ship. In this sense, the invention also aims to provide such a technique that does not cause overload or loss of space.

Un autre objectif de l'invention est de fournir une telle technique qui permette d'envisager des gains de coûts ou, à tout le moins, qui n'entraîne pas de surcoûts.Another object of the invention is to provide such a technique which makes it possible to envisage cost savings or, at the very least, which does not entail additional costs.

Un autre objectif de l'invention est de fournir une telle technique qui limite les risques encourus par le personnel qui installe l'ascenseur.Another object of the invention is to provide such a technique which limits the risks incurred by the personnel who installs the elevator.

Encore un autre objectif de l'invention est de fournir une telle technique qui puisse être utilisée quelle que soit la hauteur de la gaine d'ascenseur.Yet another object of the invention is to provide such a technique that can be used regardless of the height of the elevator shaft.

L'invention a encore pour objectif de fournir une telle technique qui soit simple de conception et facile à mettre en oeuvre.The invention also aims to provide such a technique that is simple in design and easy to implement.

Ces objectifs, ainsi que d'autres qui apparaîtront par la suite, sont atteints grâce à l'invention qui a pour objet un système d'ascenseur comprenant deux cabines et deux contrepoids, équipé d'un élément destiné à équiper une gaine d'ascenseur, et comprenant :

  • au moins une armature porteuse ;
  • au moins un rail de guidage pour cabine ;
  • au moins un rail de guidage pour contrepoids ;
  • des moyens de maintien et/ou de fixation dudit élément à ladite gaine d'ascenseur,
ledit élément étant constitué sous forme d'un ensemble pré-assemblé prêt à être monté dans ladite gaine d'ascenseur caractérisé en ce que lesdits rails de guidage pour cabine et pour contrepoids sont doublés et montés sur ladite armature de telle sorte que ledit élément puisse être monté en position sensiblement centrale dans une gaine d'ascenseur prévue pour deux cabines, dit ascenseur duplex ou multiplex.These objectives, as well as others which will appear later, are achieved thanks to the invention which relates to an elevator system comprising two cabins and two counterweights, equipped with an element intended to equip an elevator shaft. , and comprising:
  • at least one carrying frame;
  • at least one guide rail for a cabin;
  • at least one counterweight guide rail;
  • means for holding and / or fixing said element to said elevator shaft,
said element being constituted as a pre-assembled assembly ready to be mounted in said elevator shaft, characterized in that said cabin and counterweight guide rails are lined and mounted on said frame so that said element can be mounted in a substantially central position in an elevator shaft provided for two cabins, said elevator duplex or multiplex.

Grâce à l'invention, on peut réduire notablement les temps d'installation à bord des navires ou sur site par rapport aux solutions traditionnelles.Thanks to the invention, it is possible to significantly reduce the installation time on board ships or on site compared to traditional solutions.

En effet, le nombre d'opérations réalisées pour l'installation à bord ou sur site de l'ascenseur est considérablement limité. Le temps de présence des ouvriers dans la gaine d'ascenseur est donc diminué en conséquence.Indeed, the number of operations carried out for the installation on board or on site of the elevator is considerably limited. The time of presence of workers in the elevator shaft is therefore reduced accordingly.

De plus, le pré-assemblage de l'élément destiné à équiper la gaine est réalisé en usine, dans des conditions opératoires beaucoup plus confortables que dans une gaine d'ascenseur.In addition, the pre-assembly of the element intended to equip the sheath is made in the factory, in operating conditions much more comfortable than in an elevator shaft.

On diminue ainsi les risques encourus par le personnel qui installe l'ascenseur, une grande partie des tâches d'assemblage étant déjà réalisées.This reduces the risks incurred by the personnel who install the elevator, a large part of the assembly tasks already being carried out.

En outre, le pré-assemblage en usine permet d'envisager l'utilisation de techniques d'assemblage rapides, précises, et peu coûteuses, en ayant par exemple recours à des robots de soudage.In addition, the factory pre-assembly makes it possible to envisage the use of fast, precise and inexpensive assembly techniques, by having example use of welding robots.

Avantageusement, l'élément comprend également au moins une goulotte destinée à recevoir le câble d'alimentation électrique de ladite cabine d'ascenseur, l'élément comprenant avantageusement également au moins une échelle.Advantageously, the element also comprises at least one chute intended to receive the power supply cable of said elevator car, the element advantageously also comprising at least one ladder.

Ainsi constitué, l'élément contribue à réduire encore le temps nécessaire à l'installation globale de l'ascenseur, en diminuant le temps de présence des ouvriers dans la gaine d'ascenseur.Thus constituted, the element contributes to further reducing the time required for the overall installation of the elevator, by reducing the time of presence of workers in the elevator shaft.

L'installation d'un ascenseur constitué d'éléments pré-assemblés selon l'invention sur un navire comportant dix ponts nécessite alors environ 600 heures, ce qui réduit de moitié le temps d'installation par rapport aux solutions traditionnelles.The installation of an elevator consisting of pre-assembled elements according to the invention on a ship with ten decks then requires about 600 hours, which halves the installation time compared to traditional solutions.

Selon une solution préférée, ladite armature porteuse comprend au moins un longeron destiné à s'étendre horizontalement, ledit rail de guidage pour cabine étant monté sur un côté dudit longeron, l'autre côté dudit longeron portant au moins deux supports solidaires chacun d'un rail de guidage pour contrepoids, de telle sorte que ledit longeron et lesdits supports délimitent ensemble un espace de circulation pour ledit contrepoids.According to a preferred solution, said carrying frame comprises at least one spar intended to extend horizontally, said cabin guide rail being mounted on one side of said spar, the other side of said spar carrying at least two supports each secured to a spider. guide rail for counterweight, such that said spar and said supports together define a circulation space for said counterweight.

Une telle armature s'avère peu encombrante et facilite ainsi son stockage, son transport et sa mise en place, ceci tout en présentant l'ensemble des fonctionnalités traditionnelles nécessaires au fonctionnement de l'ascenseur.Such a frame is space-saving and thus facilitates its storage, transport and implementation, while presenting all the traditional features necessary for the operation of the elevator.

Préférentiellement, ladite armature est solidaire d'au moins un barreau de consolidation destiné à s'étendre sensiblement verticalement.Preferably, said armature is secured to at least one consolidation bar intended to extend substantially vertically.

Un tel barreau peut aisément être rapporté sur l'armature lors du pré-assemblage en usine. Ce barreau contribue à la rigidité de l'élément.Such a bar can easily be attached to the frame during pre-assembly at the factory. This bar contributes to the rigidity of the element.

Selon une variante envisageable, ce barreau peut être rapporté de manière temporaire sur l'armature pour la rigidité de l'élément pour le transport et l'embarquement à bord ou sur site et ensuite être enlevé une fois l'élément mis en place, la rigidité de l'élément étant alors simplement assurée par les rails de guidage pour cabine et contrepoids.According to a conceivable variant, this bar can be temporarily attached to the frame for the rigidity of the element for transport and boarding on board or on site and then be removed once the element set up, the rigidity of the element is then simply provided by the guide rails for cab and counterweight.

L'invention s'applique donc à tout type d'ascenseur, quels que soient la hauteur de la gaine et le nombre de cabines présentes dans celle-ci.The invention therefore applies to any type of elevator, regardless of the height of the sheath and the number of cabins present therein.

Dans ce cas, l'élément comprend avantageusement au moins deux longerons destinés à s'étendre dans un même plan sensiblement horizontal et portant chacun au moins un rail de guidage pour cabine et au moins deux supports solidaires chacun d'un rail de guidage pour contrepoids, lesdits longerons étant préférentiellement reliés par au moins deux traverses de telle sorte que ladite armature porteuse forme un cadre.In this case, the element advantageously comprises at least two longitudinal members intended to extend in the same substantially horizontal plane and each carrying at least one guide rail for cabin and at least two supports each secured to a guide rail for counterweight said beams preferably being connected by at least two sleepers such that said carrying frame forms a frame.

Selon cet agencement, on obtient une armature de conception particulièrement simple et efficace, permettant de supporter l'ensemble des organes essentiels en présentant une grande capacité à supporter les contraintes mécaniques qui s'exercent sur elle.According to this arrangement, a frame of particularly simple and effective design is obtained, making it possible to support all the essential organs by having a great capacity to withstand the mechanical stresses that are exerted on it.

Selon une solution préférée, ledit cadre porte au moins un barreau, dit barreau central, s'étendant parallèlement aux dits longerons en occupant une position médiane entre ceux-ci, et portant à ses extrémités, ou au voisinage de celles-ci, lesdits moyens de maintien et/ou de fixation.According to a preferred solution, said frame carries at least one bar, said central bar, extending parallel to said longitudinal members occupying a median position therebetween, and carrying at its ends, or in the vicinity thereof, said means holding and / or fixing.

Un tel barreau permet d'être fixé sur chacun des ponts et/ou entreponts, que ce soit par boulonnage, par soudage ou goujonnage.Such a bar can be fixed on each bridge and / or between-deck, whether by bolting, welding or dowelling.

Avantageusement, ladite ou lesdites goulottes sont portées par ledit ou lesdits longerons, ladite ou lesdites échelles étant avantageusement portées par ledit ou lesdits barreaux centraux.Advantageously, said channel or chutes are carried by said one or more longitudinal members, said one or more scales being advantageously carried by said central bar or said bars.

On obtient ainsi un élément sur lequel sont répartis les différents organes de telle sorte que cet élément occupe un encombrement limité, que ce soit lors de son introduction dans la gaine d'ascenseur ou une fois installé dans celle-ci.An element is thus obtained on which the various members are distributed so that this element occupies a limited space requirement, whether during its introduction into the elevator shaft or once installed in it.

Selon une solution préférée, l'élément comprend au moins deux armatures porteuses sensiblement parallèles entre elles et reliées par ledit ou lesdits barreaux de consolidation.According to a preferred solution, the element comprises at least two support frames substantially parallel to each other and connected by said consolidation bar or bars.

Le nombre d'armatures constituant l'élément pourra varier autant que de besoin, notamment en fonction du nombre de ponts et/ou entreponts et/ou de la distance qui sépare ceux-ci. En tout état de cause, plus le nombre d'armatures est grand, plus on réduit le temps d'installation d'un ascenseur comprenant les éléments correspondants.The number of reinforcements constituting the element may vary as much as necessary, in particular depending on the number of bridges and / or between spars and / or the distance that separates them. In any case, the more the number of frames is large, the more it reduces the installation time of an elevator comprising the corresponding elements.

On cherche donc à trouver un compromis entre le gain obtenu par le pré-assemblage des éléments et la difficulté engendrée par le transport et la mise en place d'un élément dont les dimensions sont augmentées.We therefore seek to find a compromise between the gain obtained by the pre-assembly of the elements and the difficulty generated by the transport and the introduction of an element whose dimensions are increased.

L'invention concerne aussi système d'ascenseur comprenant au moins un module selon la revendication 9.The invention also relates to an elevator system comprising at least one module according to claim 9.

On prévoit ainsi des moyens de coopération entre l'élément monté à la base de la gaine d'ascenseur et le module de fond de fosse. Ceci facilite donc le positionnement relatif ainsi que la fixation de l'élément de base sur le module de fond.This provides means for cooperation between the element mounted at the base of the elevator shaft and the bottom module of the pit. This thus facilitates the relative positioning as well as the fixing of the base element on the bottom module.

De plus, les armatures permettent de répartir les charges s'exerçant sur la tôle sur laquelle le module est posé. On évite ainsi de devoir renforcer au moins localement la tôle de fond, ce qui est nécessaire avec les techniques classiques pour que la tôle puisse supporter les contraintes qui s'exercent sur elle.In addition, the reinforcements allow to distribute the loads on the sheet metal on which the module is placed. This avoids having to reinforce at least locally the bottom plate, which is necessary with conventional techniques so that the sheet can withstand the constraints that are exerted on it.

Selon une solution avantageuse, ledit module de fond de fosse est constitué sous forme d'un ensemble pré-assemblé prêt à être monté.According to an advantageous solution, said bottom module is formed as a pre-assembled assembly ready to be mounted.

Ce module est donc pré-assemblé en usine, ce qui entraîne les mêmes avantages que ceux déjà énoncés précédemment concernant les éléments pré-assemblés.This module is pre-assembled at the factory, which results in the same advantages than those already stated above concerning the pre-assembled elements.

Préférentiellement, ledit module de fond de fosse porte l'un au moins des organes appartenant au groupe suivant :

  • limiteur de vitesse de la cabine ;
  • limiteur de vitesse du contrepoids ;
  • amortisseurs de la cabine ;
  • amortisseurs du contrepoids.
Preferably, said bottom module carries at least one of the following groups:
  • speed limiter of the cabin;
  • speed limiter of the counterweight;
  • booster dampers;
  • counterweight dampers.

On obtient ainsi un module complètement pré-équipé des organes classiques nécessaires au bon fonctionnement de l'ascenseur et/ou assurant les fonctions de sécurité dans celui-ci.This provides a fully pre-equipped module of the conventional bodies necessary for the proper functioning of the elevator and / or providing security functions therein.

Selon une solution avantageuse, l'élément comprend également un plancher de machinerie, et formant un élément de fermeture de ladite gaine d'ascenseur à l'extrémité supérieure de celle-ci.According to an advantageous solution, the element also comprises a floor of machinery, and forming a closing element of said elevator shaft at the upper end thereof.

Selon une solution préférée, ledit plancher comprend au moins une armoire électrique, au moins un transformateur et au moins un moteur de fonctionnement d'ascenseur et est constitué sous forme d'un ensemble pré-assemblé prêt à être monté. On évite ainsi le montage sur site des différents éléments de machinerie qui habituellement sur fait directement sur site sur une tôle de pont et/ou entrepontAccording to a preferred solution, said floor comprises at least one electrical cabinet, at least one transformer and at least one elevator operating motor and is constituted as a pre-assembled assembly ready to be mounted. This avoids the on-site assembly of the various elements of machinery that usually is done directly on site on a bridge plate and / or steer

L'invention concerne encore un procédé de montage d'un ensemble destiné à équiper une gaine d'ascenseur, selon la revendication 12.The invention further relates to a method of mounting an assembly for equipping an elevator shaft, according to claim 12.

Il apparaît clairement à travers ce procédé de montage que l'installation d'un ascenseur selon l'invention, c'est-à-dire constitué d'éléments pré-assemblés, se réduit essentiellement à des opérations de fixation des éléments sur la gaine d'ascenseur et à quelques opérations de raccordement et/ou d'accouplement des éléments entre eux.It is clear through this mounting method that the installation of an elevator according to the invention, that is to say consisting of pre-assembled elements, is reduced essentially to operations of fixing the elements on the sheath elevator and a few operations of connecting and / or coupling the elements together.

Selon une solution avantageuse, le procédé comprend une étape de mise en place dudit plancher de machinerie par simple mise en appui et fixation dudit plancher sur des supports solidaires de ladite gaine d'ascenseur.According to an advantageous solution, the method comprises a step of setting up said floor of machinery by simply placing and fixing said floor on supports integral with said elevator shaft.

Un tel plancher est installé de façon particulièrement simple dans la mesure où il suffit de le faire reposer sur ses supports et de le fixer par soudage, boulonnage ou goujonnage, des gains de temps pouvant donc à nouveau être obtenus de ce fait.Such a floor is installed in a particularly simple manner insofar as it is sufficient to rest it on its supports and fix it by welding, bolting or dowelling, time savings can therefore be obtained again from this fact.

D'autres caractéristiques et avantages de l'invention apparaîtront plus clairement à la lecture de la description suivante de deux modes de réalisation préférentiels de l'invention, donnés à titre d'exemples illustratifs et non limitatifs, et des dessins annexés parmi lesquels :

La figure 1 illustre un ascenseur présentant deux cabines 1. On précise que, comme cela va apparaître clairement par la suite, l'invention s'applique tant à des ascenseurs présentant une seule cabine qu'à des ascenseurs présentant deux cabines ou plus.The figure 1 illustrates an elevator with two cabins 1. It is pointed out that, as will become clear later, the invention applies to both elevators having a single cabin and to elevators having two or more cabins.

En référence à la figure 1, un ascenseur comprend, à l'intérieur d'une gaine 10 formant l'enveloppe de l'ascenseur :

  • des rails de guidage 2a, 2b pour la ou les cabines 1 ;
  • des contrepoids 3 ;
  • des rails de guidage 31 pour le ou les contrepoids 3 ;
  • une machinerie 4;
  • des câbles de traction 41 reliant la machinerie 4 aux contrepoids 3 et aux cabines 1 ;
  • des goulottes 8 de circulation pour les câbles électrique 81 ;
  • des échelles (non représentées sur cette figure).
With reference to the figure 1 , an elevator comprises, inside a sheath 10 forming the envelope of the elevator:
  • guide rails 2a, 2b for the one or more cabins 1;
  • counterweights 3;
  • guide rails 31 for the counterweight (s) 3;
  • machinery 4;
  • traction cables 41 connecting the machinery 4 to the counterweight 3 and the cabins 1;
  • circulating chutes 8 for electrical cables 81;
  • scales (not shown in this figure).

Selon le mode de réalisation préférentiel de l'invention illustré par la figure 4, ces organes sont regroupés sous forme d'un élément pré-assemblé, prêt à être monté dans la gaine d'ascenseur, et comprenant :

  • une armature porteuse 5, solidaire de moyens de maintien et/ou de fixation 6 destinés à être solidarisés à des parties de pont et/ou entrepont 7 d'un navire ou à tout autre élément porté directement ou indirectement par la gaine d'ascenseur ;
  • un rail de guidage 2b pour une cabine 1 ;
  • des goulottes 8 ;
  • une échelle 9 ;
  • des rails de guidage (non illustrés sur cette figure et apparaissant avec la référence numérique 31 sur les figures 2 et 3).
According to the preferred embodiment of the invention illustrated by the figure 4 these members are grouped together as a pre-assembled element, ready to be mounted in the elevator shaft, and comprising:
  • a carrying frame 5, integral with holding and / or fixing means 6 intended to be secured to deck portions and / or twig 7 of a ship or to any other element carried directly or indirectly through the elevator shaft;
  • a guide rail 2b for a cabin 1;
  • chutes 8;
  • a scale 9;
  • guide rails (not shown in this figure and appearing with the reference numeral 31 on the Figures 2 and 3 ).

Selon le mode de réalisation de la figure 4, il apparaît clairement que l'élément préfabriqué est constitué d'une succession d'armatures porteuses 5 reliées entre elles d'une part par un rail de guidage 2b pour cabine, par des rails de guidage 31 pour contrepoids et par des barreaux de consolidation 51.According to the embodiment of the figure 4 it is clear that the prefabricated element consists of a succession of carrying frames 5 interconnected on the one hand by a guide rail 2b for cab, by guide rails 31 for counterweight and by consolidation bars 51.

A titre indicatif, les armatures porteuses sont espacées les unes des autres en présentant un écartement d'environ 1,30 m entre elles et, pour des raisons de sécurité en cas d'ascenseur multiplex, une cloison s'étende verticalement entre les barreaux centraux 56, ladite cloison étant de préférence réalisée à partir d'une tôle légère ou d'un grillage.As an indication, the carrier plates are spaced from each other by having a spacing of about 1.30 m between them and, for security reasons in case of multiplex elevator, a partition extends vertically between the central bars 56, said partition being preferably made from a light sheet or mesh.

En référence à la figure 2 qui correspond à un mode de réalisation qui ne fait pas partie de l'invention, selon lequel l'ascenseur présente une cabine unique, l'armature porteuse est constituée par un longeron 52 portant sur l'un de ses côtés un rail de guidage 2b pour cabine et sur l'autre de ses côtés deux supports 53 portant les rails de guidage 31 pour le contrepoids 3.With reference to the figure 2 which corresponds to an embodiment which does not form part of the invention, according to which the elevator has a single cabin, the carrying frame is constituted by a beam 52 bearing on one of its sides a guide rail 2b for the cabin and on the other side of it two supports 53 carrying the guide rails 31 for the counterweight 3.

On note qu'ainsi constitué, le longeron 52 délimite avec les supports 53 un espace de circulation pour le contrepoids.It is noted that thus formed, the spar 52 defines with the supports 53 a circulation space for the counterweight.

Selon ce mode de réalisation, le longeron 52 porte également une goulotte 8 et un des supports 53 porte une échelle 9 (celle-ci étant, pour des raisons de sécurité évidentes, montée entre le support 53 et la gaine 10 d'ascenseur).According to this embodiment, the spar 52 also carries a chute 8 and one of the supports 53 carries a scale 9 (the latter being, for obvious safety reasons, mounted between the support 53 and the elevator shaft 10).

De plus, l'élément préfabriqué est maintenu fixement dans la gaine d'ascenseur à l'aide de moyens de fixation et/ou de maintien 6 portés d'une part par les supports 53 et d'autre part par un bras 54 fixé à une extrémité du longeron 52.In addition, the prefabricated element is fixedly held in the elevator shaft by means of fixing and / or holding means 6 carried on the one hand by the supports 53 and on the other hand by an arm 54 fixed to one end of the spar 52.

En référence à la figure 3, qui correspond à un mode de réalisation selon lequel l'ascenseur présente deux cabines 1, l'armature porteuse est constituée par un cadre comprenant deux longerons 52 reliés à leur extrémité par des traverses 53, 55.With reference to the figure 3 , which corresponds to an embodiment in which the elevator has two cabins 1, the carrying frame is constituted by a frame comprising two longitudinal members 52 connected at their end by crosspieces 53, 55.

On note que l'une de ces traverses 53 constitue également un support des rails de guidage pour les contrepoids 3, un autre support 53 s'étendant à l'intérieur du cadre de l'armature porteuse.Note that one of these crosspieces 53 also constitutes a support of the guide rails for the counterweight 3, another support 53 extending inside the frame of the carrying frame.

Tel qu'illustré, chacun des longerons 52 portent un rail de guidage pour cabine et des supports des rails de guidage pour contrepoids. Ainsi agencée, l'armature porteuse peut occuper une position centrale à l'intérieur d'une gaine d'ascenseur, en vue d'agir sur chacune des deux cabines montées de part et d'autre de l'armature.As illustrated, each of the longitudinal members 52 carries a cab guide rail and counterweight guide rail supports. Thus arranged, the carrier frame can occupy a central position inside an elevator shaft, in order to act on each of the two cabins mounted on either side of the frame.

Selon ce mode de réalisation, la fixation de l'élément pré-assemblé est réalisée à l'aide d'un barreau central 56 portant à ses extrémités des moyens de fixation 6 (ou dont les extrémités forment des moyens de fixations).According to this embodiment, the attachment of the pre-assembled element is carried out using a central bar 56 carrying at its ends fastening means 6 (or whose ends form fixing means).

Ce barreau est désigné par le terme « central » dans la mesure où ce barreau occupe une position médiane entre les longerons 52, en s'étendant parallèlement à ceux-ci.This bar is designated by the term "central" insofar as the bar occupies a median position between the longitudinal members 52, extending parallel thereto.

Tel que cela apparaît sur la figure 3, le barreau central porte des échelles 9 (les goulottes 8 étant, comme dans le cas de la cabine simple, portées par les longerons 52).As it appears on the figure 3 , the central bar carries ladders 9 (the troughs 8 being, as in the case of the single cabin, carried by the longitudinal members 52).

L'équipement d'une gaine d'ascenseur est donc réalisé par la mise en oeuvre :

  • d'un ou de plusieurs éléments pré-assemblés tels que l'un de ceux décrits précédemment ;
  • d'un module de fond de fosse, tel que celui illustré par la figure 5 ;
  • un plancher supportant la machinerie et formant l'élément de fermeture de la gaine d'ascenseur, du type du plancher illustré par la figure 6.
The equipment of an elevator shaft is thus produced by the implementation of:
  • one or more pre-assembled elements such as one of those described above;
  • a bottom module of the pit, such as that illustrated by the figure 5 ;
  • a floor supporting the machinery and forming the closing element of the elevator shaft, of the type of the floor illustrated by the figure 6 .

En référence à la figure 5, le module de fond de fosse 50 comprend deux armatures 501 et 502 constituées par des poutres présentant une section en forme de I, l'une des armatures 502 étant fixée à l'extrémité de l'autre armature 501 de telle sorte qu'elles forment un socle porteur en forme de T.With reference to the figure 5 , the pit bottom module 50 includes two armatures 501 and 502 constituted by beams having an I-shaped section, one of the armatures 502 being fixed to the end of the other armature 501 so that they form a T-shaped supporting base.

Tel que cela apparaît clairement, l'armature 501 porte des moyens de réception 5011 des rails de guidage pour cabine 2a, 2b et l'armature 502 porte des moyens de réception 5021 des rails de guidage 31 pour contrepoids.As it is clear, the armature 501 carries receiving means 5011 of the guide rails for cab 2a, 2b and the armature 502 carries means 5021 for receiving the guide rails 31 for counterweight.

Selon une caractéristique du fond de fosse, celui-ci est constitué en un ensemble pré-assemblé, prêt à être monté au fond de la gaine d'ascenseur.According to a feature of the bottom of the pit, it is constituted in a pre-assembled assembly, ready to be mounted at the bottom of the elevator shaft.

Un tel module de fond de fosse pré-assemblé est préférentiellement pré-équipé :

  • d'un limiteur de vitesse 506 de la cabine ;
  • d'un limiteur de vitesse 503 de contrepoids ;
  • d'un amortisseur 505 de la cabine ;
  • d'un amortisseur 504 du contrepoids.
Such a pre-assembled pit bottom module is preferably pre-equipped:
  • a speed limiter 506 of the car;
  • a speed limiter 503 counterweight;
  • a damper 505 of the cabin;
  • a damper 504 of the counterweight.

Tel qu'illustré par la figure 6, le plancher 60 de machinerie forme un moyen de fermeture pré-assemblé de la gaine d'ascenseur, en partie supérieure de celle-ci.As illustrated by figure 6 , the floor 60 of machinery forms a pre-assembled closure means of the elevator shaft, in the upper part thereof.

Ce plancher 62 de machinerie comporte, sur une tôle 61, deux armoires électriques 62, deux transformateurs 63 et deux moteurs 63 avec enrouleurs de câbles de traction 41.This floor 62 of machinery comprises, on a sheet 61, two electrical cabinets 62, two transformers 63 and two motors 63 with retractors of traction cables 41.

Ce plancher 60 est installé simplement en le mettant en place sur des supports 101 solidaires de la gaine 10. Ces supports 101 soutiennent le plancher 60 et assurent son maintien par simple soudage, boulonnage ou goujonnage.This floor 60 is installed simply by placing it on supports 101 integral with the sheath 10. These supports 101 support the floor 60 and ensure its maintenance by simple welding, bolting or dowelling.

Le procédé de montage d'un ensemble d'équipements pour gaine d'ascenseur est réalisé de la manière suivante :

  • pré-assemblage d'un élément (ou de plusieurs éléments selon d'autres modes de réalisation) constitué d'une série d'armature porteuse, d'un rail de guidage pour cabine, de deux rails de guidage pour contrepoids et de moyens de maintien et/ou de fixation ladite gaine d'ascenseur,
  • pré-assemblage d'un module de fond de fosse tel que celui décrit précédemment,
  • pré-assemblage d'un plancher destiné à supporter la machinerie (moteur(s), transformateur(s), armoire(s) électrique(s)...), tel que celui décrit précédemment.
The assembly method of a set of equipment for elevator shaft is carried out as follows:
  • pre-assembly of an element (or several elements according to other embodiments) consisting of a series of carrier reinforcement, a guide rail for a cabin, two guide rails for counterweights and means for maintaining and / or fixing said elevator shaft,
  • pre-assembly of a pit bottom module such as that described previously,
  • pre-assembly of a floor for supporting the machinery (motor (s), transformer (s), electrical cabinet (s) ...), as described above.

Préférentiellement, l'élément préfabriqué sera dimensionné de telle sorte qu'il soit nécessaire d'assembler deux (ou trois) éléments pour équiper toute la hauteur de la gaine d'ascenseur.Preferably, the prefabricated element will be dimensioned so that it is necessary to assemble two (or three) elements to equip the entire height of the elevator shaft.

Par ailleurs, les éléments pré-fabriqués selon l'invention, ainsi que les modules de fond de fosse et le plancher de machinerie, sont réalisés en utilisant toute technique d'assemblage appropriée, par exemple par soudage ou boulonnage.Furthermore, the pre-manufactured elements according to the invention, as well as the bottom modules of the pit and the floor of machinery, are made using any appropriate assembly technique, for example by welding or bolting.

Selon une phase initiale, le module de fond de fosse est présenté, positionné et fixé à la base de la gaine d'ascenseur.In an initial phase, the pit bottom module is presented, positioned and attached to the base of the elevator shaft.

Un rail de guidage pour la cabine est fixé dans la gaine d'ascenseur, sur une des parois de la gaine.A guide rail for the cabin is fixed in the elevator shaft on one of the walls of the shaft.

Le premier élément, enfilé dans la gaine est positionné par rapport aux moyens de réception du module de fond de fosse, ce premier élément coopérant avec le module de fond de fosse.The first element, slipped into the sheath, is positioned relative to the receiving means of the bottom module of the pit, this first element cooperating with the bottom module of the pit.

Le ou les éléments préfabriqués sont enfilés dans la gaine d'ascenseur et fixés à celle-ci.The prefabricated element or elements are threaded into the elevator shaft and fixed thereto.

Dans le cas de plusieurs éléments, ceux-ci sont également solidarisés entre eux, par exemple à l'aide de platines boulonnées. Il faut de plus, dans ce cas, connectés électriquement les éléments entre eux.In the case of several elements, these are also secured to each other, for example using bolted plates. In this case, it is also necessary to electrically connect the elements together.

Cette connectique peut alors être obtenu en prévoyant sur chacun des éléments des tronçons d'une longueur correspondant à celle des éléments. Selon une variante, l'un des éléments (préférentiellement, l'élément monté en dernier en partie haute), porte la totalité de la longueur du câblage que l'on déroule à partir de l'élément correspondant jusqu'en bas da la gaine et en fixant ce câble aux autres éléments.This connection can then be obtained by providing on each of the elements of the sections of a length corresponding to that of the elements. According to one variant, one of the elements (preferably the element mounted last in the upper part) carries the entire length of the wiring that is unwound from the corresponding element down to the bottom of the sheath. and fixing this cable to the other elements.

Les éléments préfabriqués sont conçus et montés de telle sorte que, en position finale, ils puissent être assemblés avec le bord libre que présentent les ponts et/ou entreponts à l'intérieur de la gaine d'ascenseur.The prefabricated elements are designed and assembled so that, in final position, they can be assembled with the free edge that the bridges and / or between the inside of the elevator shaft.

Cet assemblage est réalisé soit par soudage, soit par boulonnage (en particulier par la technique des goujons « auto-soudés » connus sous le nom de goujon Nelson).This assembly is carried out either by welding or by bolting (in particular by the technique of "self-welded" studs known as the Nelson stud).

Dans le cas d'un ascenseur à deux cabines, les éléments sont assemblés de façon à occuper une position centrale, formant une sorte d'arête centrale. Pour cela, le ou les éléments sont enfilés dans la gaine en étant tournés d'un quart de tour par rapport à leur position finale pour faciliter l'enfilement. Une fois présenté à la hauteur souhaité, l'élément est donc tourné d'environ 90° sur lui-même en vue d'être positionné sur les zones d'appui des ponts et/ou entreponts correspondants.In the case of a elevator with two cabins, the elements are assembled so as to occupy a central position, forming a sort of central ridge. For this, the element or elements are threaded into the sheath being rotated a quarter turn relative to their final position to facilitate donning. Once presented at the desired height, the element is rotated about 90 ° on itself to be positioned on the support zones of the bridges and / or between centers.

Selon une phase finale, le plancher support de la machinerie est positionné sur des supports solidaires de la gaine.
Bien entendu, le montage complet comprend d'autres étapes classiques, concernant le câblage, l'éclairage...According to a final phase, the support floor of the machinery is positioned on supports integral with the sheath.
Of course, the complete assembly includes other conventional steps, concerning wiring, lighting ...
