Abstract

The displacement device for the lift cabin (2) comprises a vertical rail (9) and a driving surface (10) applied on the rail. The driving surface is carried by the driving strand of a wide belt which is applied on the plane surface of the rail. The driving surface comprises two active surfaces tightly gripping the rail and applied to the rail plane surfaces by a spring applying each belt carrier assembly. An Independent claim is included for a lift cabin provided with the displacement device.

Description

L'invention se rapporte à un dispositif de déplacement d'une cabine d'ascenseur.The invention relates to a device for moving an elevator car.

Elle se rapporte également à la cabine d'ascenseur pourvue dudit dispositif de déplacement.It also relates to the elevator car provided with said displacement device.

Classiquement, un ascenseur est constitué par une cabine qui se déplace dans une cage d'ascenseur, cela au moyen d'un dispositif de déplacement.Conventionally, an elevator is constituted by a cabin that moves in an elevator shaft, by means of a displacement device.

Classiquement, on connaît deux types de dispositifs de déplacement pour une cabine d'ascenseur.Conventionally, two types of displacement devices are known for an elevator car.

Le premier type consiste à utiliser un vérin hydraulique qui, posé à la base de la cage d'ascenseur, pousse sur le fond de la cabine d'ascenseur.The first type is to use a hydraulic cylinder which, placed at the base of the elevator shaft, pushes on the bottom of the elevator car.

Ce type de dispositif de déplacement trouve rapidement sa limite dans l'amplitude du déplacement de la cabine.This type of displacement device quickly finds its limit in the amplitude of the displacement of the cabin.

Pour remédier à cela, le deuxième type de dispositif consiste à suspendre la cabine à un câble et à enrouler ou dérouler le câble à l'aide d'un moyen moteur.To remedy this, the second type of device is to suspend the cabin to a cable and to wind or unwind the cable using a motor means.

Plus généralement, d'une part, le câble est accroché par l'une de ses extrémités à la cabine et par l'autre extrémité à un contrepoids et, d'autre part, la poulie d'adhérence constitue le moyen de déplacement.More generally, on the one hand, the cable is hooked by one of its ends to the cabin and the other end to a counterweight and, on the other hand, the traction sheave constitutes the moving means.

A cet effet, la poulie d'adhérence doit être de taille suffisante pour que l'enroulement entre la poulie et le câble soit satisfaisante pour éviter tout risque de glissement.For this purpose, the traction sheave must be of sufficient size so that the winding between the pulley and the cable is satisfactory to avoid any risk of slipping.

La poulie est bien évidemment calée en rotation sur un arbre entraîné en rotation par un moteur, le plus souvent, via un réducteur de vitesse.The pulley is of course wedged in rotation on a shaft driven in rotation by a motor, most often via a speed reducer.

On déplore avec ce type de dispositif un encombrement relativement important.We deplore with this type of device a relatively large size.

On connaît un autre dispositif qui consiste en l'utilisation de deux galets dont un galet de traction.Another device is known which consists of the use of two rollers including a traction roller.

Les deux galets sont fixés sur une platine solidaire de la cabine et viennent pincer un rail.The two rollers are fixed on a fixed plate of the cabin and come to pinch a rail.

Un ressort tendu entre les deux galets développe une force d'application.A spring stretched between the two rollers develops an application force.

Un tel dispositif présente, d'une part, une capacité motrice très faible et, d'autre part, génère des bruits importants.Such a device has, on the one hand, a very low power capacity and, on the other hand, generates significant noise.

En effet, le bruit que font ces ascenseurs en se déplaçant doit de plus en plus être réduit sous peine de ne pouvoir être commercialisé.In fact, the noise that these lifts make when moving must be reduced more and more or they will not be marketed.

Avec le système à galet, pour obtenir une adhérence suffisante, il faut, d'une part, exercer une force importante pour rapprocher les galets et donc appliquer le galet moteur sur le rail et, d'autre part, utiliser un galet en matière relativement souple.With the roller system, to obtain sufficient adhesion, it is necessary, on the one hand, to exert a large force to bring the rollers closer together and thus apply the motor roller to the rail and, on the other hand, to use a relatively flexible.

De ces deux paramètres, il résulte que, lors d'un arrêt prolongé, par exemple le week-end ou la nuit, il se produit une déformation locale du galet qui se répercute par une augmentation de bruit lorsque le galet roule sur le rail.From these two parameters, it follows that, during a prolonged stop, for example at the weekend or at night, there is a local deformation of the roller which is reflected by an increase in noise when the roller rolls on the rail.

Cette déformation locale peut disparaître dans le temps mais réapparaît toujours.This local deformation may disappear over time but still reappears.

On connaît, notamment du document US-3.381.541, également l'utilisation d'un système moteur comportant deux courroies larges circulant entre deux poulies de renvoi.US Pat. No. 3,381,541 also discloses the use of an engine system comprising two wide belts circulating between two return pulleys.

Un système à pression d'air tend à appliquer la courroie sur une surface d'appui qui peut être le câble de suspension de la cabine.An air pressure system tends to apply the belt to a bearing surface which may be the cab suspension cable.

Un tel système présente des inconvénients en ce sens qu'il faut disposer d'un générateur d'air comprimé qui est, bien évidemment, aussi encombrant voire plus encombrant que le moteur entraînant l'arbre de rotation de la poulie.Such a system has drawbacks in that it is necessary to have a compressed air generator which is, of course, as bulky or even more bulky than the motor driving the rotation shaft of the pulley.

Par ailleurs, il est impossible d'atteindre des pressions de contact entre la courroie et la surface d'appui suffisante pour déplacer de lourdes charges.Furthermore, it is impossible to achieve contact pressures between the belt and the bearing surface sufficient to move heavy loads.

Il faut également synchroniser le déplacement des courroies pour obtenir un fonctionnement correct.It is also necessary to synchronize the movement of the belts to obtain a correct operation.

On connaît également du document DE-39.39.762, l'utilisation d'un système à crémaillère permettant l'entraînement d'une cabine le long d'un rail.Also known from DE-39.39.762, the use of a rack system for driving a cabin along a rail.

Ce type de système présente toutefois différents inconvénients et notamment génère des bruits importants.This type of system, however, has various disadvantages and in particular generates significant noise.

L'invention se propose d'apporter une solution aux problèmes notamment évoqués plus haut.The invention proposes to provide a solution to the problems mentioned above.

A cet effet, l'invention a pour objet un dispositif de déplacement destiné à être fixé sur une cabine d'ascenseur suspendue par un câble qui, passé sur une poulie de renvoi, est soumise à l'action d'un contrepoids, ce dispositif de déplacement comprenant, d'une part, au moins un rail vertical et, d'autre part, une surface motrice s'appliquant sur le rail, ce dispositif étant caractérisé en ce que :

  • la surface motrice est présentée par le brin menant d'une large courroie s'appliquant sur une surface plane du rail précité et
  • cette surface motrice comprend deux surfaces dites actives qui, enserrant le rail, sont sollicitées vers les surfaces planes du rail par des moyens d'application appliquant chaque ensemble porteur de ladite courroie.
For this purpose, the subject of the invention is a displacement device intended to be fixed on an elevator car suspended by a cable which, when passed over a return pulley, is subjected to the action of a counterweight, this device displacement device comprising, on the one hand, at least one vertical rail and, on the other hand, a driving surface applying to the rail, this device being characterized in that:
  • the driving surface is presented by the leading strand of a wide belt applied on a flat surface of the aforementioned rail and
  • this driving surface comprises two so-called active surfaces which, enclosing the rail, are biased towards the flat surfaces of the rail by application means applying each carrier assembly of said belt.

L'invention sera bien comprise à l'aide de la description ci-après faite à titre d'exemple non limitatif en regard du dessin ci-annexé qui représente schématiquement :

  • figure 1 : un ascenseur,
  • figure 2 : une vue en plus gros plan d'une variante de réalisation,
  • figure 3 : une coupe selon III-III de la figure 2,
  • figures 4 à 6 : différents montages du dispositif de déplacement,
  • figure 7 : une vue d'un ascenseur dont le centre de gravité est décalé,
  • figure 8 : un ensemble moteur + courroie d'entraînement.
The invention will be better understood using the following description given by way of non-limiting example with reference to the attached drawing which schematically shows:
  • figure 1: an elevator,
  • FIG. 2: a closer view of an alternative embodiment,
  • FIG. 3: a section along III-III of FIG. 2,
  • FIGS. 4 to 6: various assemblies of the displacement device,
  • FIG. 7: a view of an elevator whose center of gravity is offset,
  • Figure 8: a motor assembly + drive belt.

En se reportant au dessin, on voit un ascenseur 1.Referring to the drawing, we see an elevator 1.

Cet ascenseur comprend au moins une cabine 2 suspendue par un câble 3 qui, passé sur une poulie 4 de renvoi, est soumise à l'action d'un contrepoids 5.This elevator comprises at least one cabin 2 suspended by a cable 3 which, passed over a pulley 4 of return, is subjected to the action of a counterweight 5.

Cette cabine d'ascenseur se déplace dans une cage ou trémie.This elevator car moves in a cage or hopper.

Généralement, la cabine est portée par un support 6 appelé arcade 6, lequel est guidé en translation dans des guides 7 verticaux équipant la trémie.Generally, the cabin is carried by a support 6 called arcade 6, which is guided in translation in vertical guides 7 equipping the hopper.

Ces guides sont réalisés par des profilés en Té.These guides are made by T-sections.

Des galets et contre-galets réalisent un guidage de cette arcade ou cabine tout en autorisant un jeu de fonctionnement.Rollers and counter rollers guide this arcade or cabin while allowing a game of operation.

Pour sa motorisation, au moins indirectement, la cabine porte un moyen 8 de déplacement.For its motorization, at least indirectly, the cabin carries a means 8 of displacement.

Ce moyen 8 de déplacement est généralement fixé de manière démontable sur l'arcade.This means 8 of displacement is generally removably attached to the arch.

Ce dispositif 8 de déplacement comprend, d'une part, au moins un rail 9 vertical fixé dans la cage d'ascenseur et, d'autre part, une surface 10 motrice s'appliquant sur le rail.This displacement device 8 comprises, on the one hand, at least one vertical rail 9 fixed in the elevator shaft and, on the other hand, a driving surface 10 applied to the rail.

Selon une caractéristique :

  • la surface motrice 10 est portée par le brin menant d'une large courroie 100 s'appliquant sur une surface plane du rail 9 précité et
  • cette surface motrice 10 comprend deux surfaces 10A, 10B dites actives qui, enserrant le rail, sont sollicitées vers les surfaces planes du rail par des moyens 11 d'application appliquant chaque ensemble porteur de ladite courroie.
According to one characteristic:
  • the driving surface 10 is carried by the driving strand of a wide belt 100 applying on a flat surface of the aforementioned rail 9 and
  • this driving surface 10 comprises two so-called active surfaces 10A, 10B which, enclosing the rail, are biased towards the flat surfaces of the rail by means of application applying each carrier assembly of said belt.

Chaque courroie est tendue entre deux organes 12 de renvoi dont au moins l'un est accouplé par un transmission à un moteur.Each belt is stretched between two return members 12 of which at least one is coupled by a transmission to a motor.

Chaque ensemble porteur est fixé mécaniquement à l'arcade porteur de la cabine.Each carrier assembly is mechanically attached to the carrier arch of the cabin.

Dans une forme de réalisation, le dispositif 8 de déplacement est situé à la base de la cabine.In one embodiment, the displacement device 8 is located at the base of the cabin.

Dans une variante de réalisation, le dispositif 8 de déplacement est situé au dessus de la cabine.In an alternative embodiment, the displacement device 8 is located above the cabin.

Les organes 12 de renvoi sur lesquels sont tendues les courroies sont relativement de faible diamètre mais les moteurs sont quant à eux plus encombrants.The return members 12 on which are stretched the belts are relatively small diameter but the engines are more bulky.

On a représenté trois modes de montage.Three mounting modes are shown.

Sur le premier mode, les brins menants sont au même niveau et les moteurs sont décalés vers l'extérieur.In the first mode, the leading strands are at the same level and the motors are shifted outwards.

Une courroie de transmission ou directement la courroie 100 assure la liaison entre le moteur et un des organes de renvoi.A transmission belt or directly the belt 100 provides the connection between the motor and one of the return members.

Pour les deux autres modes de montage, les brins menants sont situés à des niveaux différents ce qui permet d'accoupler directement les moteurs sur l'axe de rotation de l'organe de renvoi.For the other two mounting modes, the driving strands are located at different levels which allows to directly couple the motors on the axis of rotation of the return member.

Le décalage des niveaux peut être plus ou moins limité.The shift of the levels can be more or less limited.

Dans le cas de la figure 5, qui est la solution la plus compacte, il peut, selon le choix du moteur dans les puissances nécessaires, n'y avoir quasiment pas de décalage.In the case of Figure 5, which is the most compact solution, it can, depending on the choice of motor in the required power, there is almost no offset.

Pour bénéficier d'un maximum de surface d'appui de chaque brin menant, un contre-appui 13 est disposé derrière la face active du brin menant.To benefit from a maximum of support surface of each driving strand, a counter-support 13 is disposed behind the active face of the driving strand.

Avantageusement, ce contre-appui est réalisé par une série de rouleaux limitant ainsi frottements et l'usure de la courroie.Advantageously, this counter-support is made by a series of rollers thus limiting friction and wear of the belt.

Les rouleaux sont libres en rotation et alignés dans un plan.The rolls are free in rotation and aligned in a plane.

Un tendeur 20 permet le réglage de la tension de la courroie.A tensioner 20 allows the adjustment of the tension of the belt.

La surface des brins menants en contact avec ie rail est primordiale car de la qualité de ce contact dépend le risque de glissement par perte d'adhérence.The surface of the leading strands in contact with the rail is essential because the quality of this contact depends on the risk of slippage due to loss of adhesion.

L'appui des brins menants sur la surface du rail est important mais il dépend du centre de gravité de la charge.The support of the leading strands on the surface of the rail is important but it depends on the center of gravity of the load.

Dans un système à double galets d'appui, la position du centre de gravité de la cabine ne modife en rien le couple car l'appui est un appui linéaire mais tel n'est pas le cas pour un appui d'une courroie tendue.In a system with double support rollers, the position of the center of gravity of the cabin does not alter the torque because the support is a linear support but this is not the case for a support of a tensioned belt.

Il est en effet bien rare que le centre de gravité de cette charge soit centré.It is indeed rare that the center of gravity of this load is centered.

Il est bien souvent excentré d'où un basculement de la cabine ou arcade.It is often eccentric where a tilting of the cabin or arcade.

Dans la solution retenue, la rotation engendrée par le basculement de la cabine engendre des forces de réaction qui sont reprises à parts égales par les organes de renvoi symétriques par rapport à un point médian. La figure 7 montre de manière exagérée cela.In the solution adopted, the rotation generated by the tilting of the cabin generates reaction forces which are taken in equal parts by the symmetrical return members with respect to a midpoint. Figure 7 exaggerates this.

Si on examine l'une des courroies 10, on voit que l'un des deux organes de renvoi exerce une force supplémentaire sur le rail tandis que l'autre est détesté mais le couple du moteur ne varie pas.If we examine one of the belts 10, we see that one of the two return members exerts an additional force on the rail while the other is hated but the engine torque does not vary.

De la même manière, le même phénomène se produit sur l'autre courroie.In the same way, the same phenomenon occurs on the other belt.

De par ce principe, les couples d'entraînement identiques appliqués aux courroies ne provoqueront pas de glissement différentiel.By this principle, the identical drive torques applied to the belts will not cause differential slip.

Ainsi, comme le guidage de la cabine se fait au moyen de galets disposés au contact du guide ou rail pour l'appui des moyens de déplacement, l'amplitude du basculement est faible.Thus, as the guidance of the cabin is done by means of rollers arranged in contact with the guide or rail for the support of the displacement means, the amplitude of the tilting is low.

Les moteurs, de caractéristiques électrotechniques identiques, entraînant les axes des organes de renvoi, par exemple, peuvent se coupler et être asservis électriquement en parallèle, la symétrie des contraintes ne devant plus être assurée par un couplage mécanique.Motors, of identical electrotechnical characteristics, driving the axes of the return members, for example, can couple and be enslaved electrically in parallel, the symmetry of the constraints must no longer be provided by a mechanical coupling.

Selon une caractéristique intéressante, le rail 9 sur lequel s'appuient les brins menants des courroies est présenté par les guides 7 assurant le positionnement de la cabine d'ascenseur dans son déplacement vertical.According to an interesting characteristic, the rail 9 on which the leading strands of the belts are based is presented by the guides 7 ensuring the positioning of the elevator car in its vertical displacement.

Il s'agit de la branche verticale du guide qui, généralement, a une section en Té.This is the vertical branch of the guide, which usually has a tee section.

L'ensemble constitué par le moteur, ies organes de renvoi et la courroie qui s'applique sur le rail, est appliqué vers le rail au moyen de ressorts 11A prenant appui sur la cabine ou l'arcade.The assembly constituted by the motor, the return members and the belt which is applied on the rail, is applied towards the rail by means of springs 11A bearing on the cabin or the arch.

Ces ressorts autorisent un léger basculement et permettent d'avoir une pression de contact de l'ordre de 15 à 20 kg/cm2.These springs allow a slight tilting and allow to have a contact pressure of the order of 15 to 20 kg / cm 2 .
