Abstract

The invention relates to an elevator drive device using the counterweight (42) thereof. A small jack is disposed on a pedestal (30) which can propel the elevator car (48) at between 3 and 9 times the travelling speed of the rod and move the elevator car (48) by a height that is equal to between 3 and 9 times the length of the jack (14). The diameter and the quantity of oil used are greatly affected by the reduced size of the jack. The inventive system can be used to reach heights never achieved by standard hydraulic elevators. Said system also allows for the installation of the jack outside the casing, which, in certain cases, can prove very important.

Description

ENTRAINEMENT D'UN ASCENSEUR PAR LE CONTREPOIDSCOUNTERWEIGHT LIFT TRAINING
La présente invention à pour objet un mode de traction pour les ascenseurs ou autre installation similaire.The present invention relates to a mode of traction for elevators or other similar installation.
Dans la présente demande de brevet, pour ascenseur ou similaire, il faut entendre non seulement les ascenseurs au sens propre du terme mais également des monte-charge ou des dispositifs monte handicapés.In the present patent application, for an elevator or the like, it is necessary to understand not only elevators in the literal sense of the term but also freight elevators or disabled mobility devices.
La motorisation pour l'entraînement d'un ascenseur est en générale physiquement étroitement liée, notamment à l'aplomb de la cabine, peu importe si celle-ci est hydraulique ou électrique à adhérence ou à tambour. En règle générale pour un ascenseur électrique à adhérence le moteur se trouve entre la cabine et le contrepoids ce dernier représente le masse mort de la cabine plus 50% de la charge utile.The motorization for the drive of an elevator is in general physically closely linked, in particular with the plumb of the cabin, it does not matter if this one is hydraulic or electric with grip or with drum. As a general rule for an electric lift with grip, the motor is between the car and the counterweight, the latter representing the dead mass of the car plus 50% of the payload.
Pour un ascenseur électrique à tambour, il n'y a pas de contrepoids, la machine se trouve en générale à proximité. Ce type d'ascenseur est préconisé pour les petites charges. Pour les ascenseurs hydrauliques le vérin se trouve soit sous la cabine en poussée directe ; ou sur le côté latéral de la cabine, avec une liaison par câbles.For an electric drum lift, there is no counterweight, the machine is generally nearby. This type of elevator is recommended for small loads. For hydraulic elevators the cylinder is either under the cabin in direct thrust; or on the lateral side of the cabin, with a cable connection.
La présente demande de brevet à pour but de répondre à toutes sortes d'installations d'ascenseurs notamment pour :The purpose of this patent application is to respond to all kinds of elevator installations, in particular for:
Des charges à transporter petites ou importantes. Pour des hauteurs plus grandes, comparativement aux ascenseurs hydrauliques existants.Small or large loads to transport. For greater heights, compared to existing hydraulic elevators.
A des vitesses jamais atteintes par les appareils hydrauliques. Une économie d'énergie incomparable à l'ascenseur hydraulique actuel. Matériel standard et très compact. Nombre de démarrage/heure illimité. - Faible quantité d'huile en comparaison des appareils existants.At speeds never reached by hydraulic devices. Energy savings incomparable to the current hydraulic elevator. Standard and very compact material. Unlimited number of starts / hour. - Low amount of oil compared to existing devices.
Motorisation à proximité en cuvette ou à distance. Vérin à proximité ou à distance.Motorization nearby in a bowl or remotely. Cylinder nearby or remote.
Ces quelques exemples de caractéristiques dans le monde professionnel des ascenseurs sont surprenants et très étonnants, les ascenseurs hydrauliques actuels sont totalement à l'opposé.These few examples of characteristics in the professional world of elevators are surprising and very surprising, current hydraulic elevators are completely the opposite.
De façon plus précise, l'invention concerne un ou plusieurs arrangements qui permettent le mouvement de l'ascenseur, sans les contraintes habituelles de positionnement. La machinerie et le vérin peuvent être indifféremment, dans la gaine ou à distance, cette possibilité nouvelle facilite, et simplifie l'installation de l'ascenseur.More specifically, the invention relates to one or more arrangements which allow movement of the elevator, without the usual positioning constraints. The machinery and the cylinder can be indifferently, in the sheath or remotely, this new possibility facilitates and simplifies the installation of the elevator.
BREF RAPPEL DE L'HYDRAULIQUE EXISTANTBRIEF SUMMARY OF EXISTING HYDRAULICS
La disposition actuelle d'un vérin peut être sous la cabine, cette disposition est dite en prise directe le vérin dans ce cas il est de même longueur que la hauteur totale de la course. En fonction de la hauteur de la gaine, et de la charge à transporter, celui-ci est généralement conçu, dimensionné et fabriqué suivant les caractéristiques concernant une affaire précise. Les caractéristiques de hauteur et de charge sont indispensables pour déterminer le diamètre, afin d'éviter le phénomène de flambage. Un grand vérin nécessite une quantité d'huile en conséquence, une pompe de grande capacité et une puissance électrique en rapport.The current arrangement of a jack can be under the cabin, this arrangement is said to be in direct engagement with the jack in this case it is the same length as the total height of the stroke. Depending on the height of the sheath, and the load to be transported, it is generally designed, dimensioned and manufactured according to the characteristics relating to a specific case. The height and load characteristics are essential to determine the diameter, in order to avoid the phenomenon of buckling. A large cylinder requires a corresponding quantity of oil, a large capacity pump and a corresponding electrical power.
Un trou important dans le sol est également prévu pour installer le vérin.A large hole in the ground is also provided to install the cylinder.
La taille du vérin peut être réduite de moitié si celui-ci est installé latéralement sur une chandelle, il est relié à la cabine par des câbles. Dans tous les cas le dimensionnement est en conséquences. Du fait que la production des vérins est sur mesure, cela implique forcément des délais et des coûts non négligeables.The size of the cylinder can be reduced by half if it is installed laterally on a jack, it is connected to the cabin by cables. In all cases the dimensioning is in consequence. Because the production of the cylinders is tailor-made, this inevitably involves significant delays and costs.
DESCRIPTION DE LA DEMANDE DU BREVETDESCRIPTION OF THE PATENT APPLICATION
Utilisation d'un vérin de 3 m pour une course de 3 m à 27m de hauteur. Celui-ci est moufle et peut être disposer sur un socle, au sol,, à n'importe quel endroit dans la gaine, en périphérie de la cabine, sauf bien entendu dans la zone de la face de service. Il peut être installer sur les 4 côtés de la cabine, lorsque le vérin est installé à l'extérieur de la gaine. La hauteur du vérin n'est pas limitative, le rapport vérin poulie est de 3 fois à 9 fois au maximum, à savoir :Use of a 3 m cylinder for a 3 m to 27 m height stroke. This is a muffle and can be placed on a base, on the ground, anywhere in the sheath, on the periphery of the cabin, except of course in the area of the service face. It can be installed on the 4 sides of the cabin, when the cylinder is installed outside the sheath. The height of the jack is not limiting, the pulley jack ratio is 3 times to 9 times maximum, namely:
Au minimum une poulie sur la têt de vérin, et une en dessous du vérin plus le câble qui remonte cela fait un rapport de 3 fois. Au maximum : pour 4 poulies fixées sur la partie supérieure de la tige et 4 poulies en dessous du vérin soit 8 poulies, plus le câble qui remonte cela fait neuf brins x 3m = 27m de hauteur. Un vérin de 6 m par exemple équivaut à 54m de hauteur de course.At least one pulley on the cylinder head, and one below the cylinder plus the cable that goes up makes a ratio of 3 times. Maximum: for 4 pulleys fixed on the upper part of the rod and 4 pulleys below the jack, i.e. 8 pulleys, plus the cable which goes up, this makes nine strands x 3m = 27m in height. A cylinder of 6 m for example is equivalent to 54m of stroke height.
1er arrangement : 1st arrangement:
Une extrémité des câbles est fixée sur le socle du support vérin, ces derniers sont enroulés entre un jeu de poulies situé sur la traverse fixe appelée socle, et des poulies fixées sur la traverse mobile.One end of the cables is fixed on the base of the jack support, the latter are wound between a set of pulleys located on the fixed cross member called the base, and pulleys fixed on the mobile cross member.
La traverse mobile est solidement fixée sur l'extrémité de la tige du vérin. Lorsque le vérin est actionné le moufle en s'écartant, tire sur les câbles. La 2eme extrémité des câbles étant fixée sur le contrepoids, est tiré vers le bas, la cabine alors se déplace dans le sens montée. Cet arrangement nécessite une masse inférieure dans le contrepoids à celle de la cabine à vide, pour que celle-ci soit toujours en tension. 2ème arrangement :The movable cross member is securely attached to the end of the cylinder rod. When the jack is actuated, the muffle moves away, pulls on the cables. The 2 nd end of the cables being fixed on the counterweight, is pulled down, the cabin then moves in the assembled direction. This arrangement requires a lower mass in the counterweight than that of the vacuum cabin, so that the latter is always under tension. 2nd arrangement:
Une extrémité des câbles est fixée sur le socle du support vérin, ces derniers sont enroulés entre un jeu de poulies situé sur la traverse fixe appelée socle, et des poulies fixées sur la traverse mobile. La traverse mobile est solidement fixée sur l'extrémité de la tige du vérin. Lorsque le vérin est actionné le moufle en s'écartant, tire sur les câbles. La 2ème extrémité des câbles remonte vers la partie haute de la gaine, sur une poulie de renvoi, et redescend sur la partie supérieure de la cabine, sur un point de traction. La cabine alors se déplace dans le sens montée, le contrepoids est entraîné vers le bas. Cet arrangement nécessite une masse inférieure dans le contrepoids à celle de la cabine à vide, pour que celle-ci soit toujours en tension.One end of the cables is fixed on the base of the jack support, the latter are wound between a set of pulleys located on the fixed cross member called the base, and pulleys fixed on the mobile cross member. The movable cross member is securely attached to the end of the cylinder rod. When the jack is actuated, the muffle moves away, pulls on the cables. The 2nd cable end rises towards the upper part of the sheath, over a deflecting pulley, and down on the upper part of the cabin, on a traction point. The cabin then moves in the mounted direction, the counterweight is driven downwards. This arrangement requires a lower mass in the counterweight than that of the vacuum cabin, so that the latter is always under tension.
Pour les ascenseurs de charges jusqu'à 1000 kg maximum, la traction peut se faire par la partie supérieure de la cabine identique au 2eme arrangement, mais sans le contrepoids. Le groupe moteur pompe, peut être installé, à l'intérieur de la gaine en cuvette ou à l'extérieur, il est compact, et ne nécessite aucun réglage. Une visite annuelle suffit.For lifts loads up to 1000 kg maximum traction can be achieved by the upper part of the same cabin 2nd arrangement, but without the counterweight. The pump motor group can be installed inside the bowl sheath or outside, it is compact and requires no adjustment. An annual visit is sufficient.

DESCRIPTION DETAILLEE DE LA DEMANDE DE BREVET Se référant tout d'abord à la 1, 2, 3eme figure, on va décrire les éléments qui composent un mode de traction hydraulique selon l'invention. Sur les figures simplifiées, sont représentés figure 1 vue du dessus, deux sets de deux poulies 10 montées sur un axe dans un support 1 1, chaque set 10 est relié par le point de fixation 12, entre les deux sets 13, se trouve le corps du vérin 14. Les deux sets de poulies 10 de la figure 1 sont reliés par les points 12 à la traverse mobile 20, figure 2, sur les points de fixations 22, à l'aide d'un montant 15 (visible figure 4) par set 10, les montants 15 (visible sur la figure 4) selon l'invention permettent de réduire la distance entre les poulies du socle et de la traverse mobile 20, d'une part et d'être toujours en dessous de la cabine même quand celle-ci se trouve à l'étage le plus bas. La traverse mobile 20, est fixée sur l'extrémité de la tige du vérin 25. De part et d'autres de la traverse un coulisseau 23 est fixé pour guider la traverse mobile 20, dans les rails.DETAILED DESCRIPTION OF THE PATENT APPLICATION Referring first to the 1, 2, 3 rd figure, we will describe the elements that make up a hydraulic traction mode according to the invention. In the simplified figures, FIG. 1 is a view from above, two sets of two pulleys 10 mounted on an axis in a support 1 1, each set 10 is connected by the fixing point 12, between the two sets 13, is the cylinder body 14. The two sets of pulleys 10 in FIG. 1 are connected by the points 12 to the movable cross member 20, FIG. 2, on the fixing points 22, using an upright 15 (visible in FIG. 4 ) per set 10, the uprights 15 (visible in FIG. 4) according to the invention make it possible to reduce the distance between the pulleys of the base and of the movable cross member 20, on the one hand and to always be below the cabin even when it is on the lowest floor. The movable cross member 20 is fixed on the end of the rod of the jack 25. On either side of the cross member a slide 23 is fixed to guide the movable cross member 20, in the rails.
La figure 3, représente un socle 30, sur lequel sont fixées 4 poulies 31, dont une en diagonale 32 pour échapper l'encombrement du vérin . Un point fixe 34, pour les câbles de traction, est fixé selon cet arrangement dans l'angle du socle 30, il peut suivant la configuration être installer dans un autre angle du socle 30.Figure 3 shows a base 30, on which are fixed 4 pulleys 31, one diagonally 32 to escape the size of the cylinder. A fixed point 34, for the traction cables, is fixed according to this arrangement in the angle of the base 30, it can, depending on the configuration, be installed in another angle of the base 30.
Un premier et un deuxième ensemble de poulies montées libres respectivement sur des axes horizontaux solidaires respectivement de la traverse mobile et du socle.A first and a second set of pulleys mounted free respectively on horizontal axes secured respectively to the movable cross member and the base.
En se référant maintenant à la figure 4, on va décrire plus en détail un mode préféré de réalisation du dispositif moteur pour ascenseur dont le principe a déjà été exposé en relation avec les figures précédentes.Referring now to FIG. 4, a preferred embodiment of the motor device for an elevator will be described in more detail, the principle of which has already been explained in relation to the preceding figures.
Lorsque la cabine 48 est au point le plus bas, le contrepoids 42 est au plus haut, tandis que la tige du vérin 25 est entièrement rentrée. Le corps du vérin 14 étant solidaire du socle 30, seule la tige 25 se déploie lorsque le vérin est actionné entraînant dans sa trajectoire la traverse supérieure mobile 20, libre de se déplacer verticalement. La réglementation en matière d'ascenseur exige l'emploi de plusieurs câbles appelés nappe de câbles, pour la simplification de la description un seul câble est représenté. Deux câbles différents sont utilisés ; -le premier permet de maintenir en suspension la cabine à une extrémité et à l'autre extrémité son contrepoids.When the cabin 48 is at the lowest point, the counterweight 42 is at the highest, while the rod of the jack 25 is fully retracted. The body of the actuator 14 being integral with the base 30, only the rod 25 is deployed when the actuator is actuated, causing in its trajectory the movable upper cross member 20, free to move vertically. The elevator regulations require the use of several cables called cable plies, for the simplification of the description only one cable is shown. Two different cables are used; -the first keeps the cabin in suspension at one end and its counterweight at the other end.
-celui qui nous intéresse, le deuxième câble 40 passe sur lesdits ensembles de poulies pour constituer un moufle. Une première extrémité dudit câble 40 étant solidaire du point fixe 41 du socle 43, l'autre extrémité passe par une poulie de renvoi 49, qui est située à l'aplomb du contrepoids 42. La poulie de renvoi 49 peut être maintenue écartée par des traverses 48 par exemple ou être fixée au sol, si la nature de celui-ci le permet. Le câble 40 se dirige, sur un point d'ancrage 46 situé sur la partie basse du contrepoids 42.that which interests us, the second cable 40 passes over said sets of pulleys to constitute a block. A first end of said cable 40 being secured to the fixed point 41 of the base 43, the other end passes through a deflection pulley 49, which is located directly above the counterweight 42. The deflection pulley 49 can be kept apart by sleepers 48 for example or be fixed to the ground, if the nature of this allows. The cable 40 runs on an anchor point 46 located on the lower part of the counterweight 42.
On comprend que la course du vérin, à simplement pour but de provoquer l'écartement du moufle, entre la traverse mobile 45, qui est libre de se déplacer verticalement par rapport au socle 43. En provoquant l'écartement des deux ensembles de poulies, on provoque la descente du contrepoids 42. La descente du contrepoids à pour effet bien entendu de faire monter la cabine 48, d'une hauteur qui est égale au déplacement de la tige du vérin 25, multiplié par le nombre de brins bu câble passant sur les poulies constituant le moufle. Par exemple chaque ensemble de poulies comporte quatre poulies, la course effective de l'ascenseur est de 9 fois la valeur de déplacement de la tige. Un minimum de 4 poulies peut être installer soit une poulie par set c'est à dire 2 poulies au total sur la traverse mobile et 2 poulies sur le socle ce qui fait 5 brins, soit un déplacement de 5 fois la longueur de la tige et une vitesse de 5 fois la vitesse de sortie de la tige. Dans le cas décrit un maximum de 2 poulies par set, soit un total de 4 poulies pour la traverse mobile, et 4 poulies dans le socle, d'où le rapport de 9. On comprend également que la vitesse de déplacement de l'ascenseur est égale à la vitesse de déplacement de la tige du vérin, multipliée également par le nombre de brins. Dans l'exemple considéré, cette vitesse est donc multipliée par 9.It is understood that the stroke of the jack, simply for the purpose of causing the separation of the block, between the movable cross member 45, which is free to move vertically relative to the base 43. By causing the separation of the two sets of pulleys, the counterweight 42 is lowered. The lowering of the counterweight naturally has the effect of raising the cabin 48, by a height which is equal to the displacement of the rod of the jack 25, multiplied by the number of strands drunk cable passing over the pulleys constituting the block. For example, each set of pulleys has four pulleys, the effective stroke of the elevator is 9 times the displacement value of the rod. A minimum of 4 pulleys can be installed, either a pulley per set, i.e. 2 pulleys in total on the mobile crossmember and 2 pulleys on the base which makes 5 strands, or a displacement of 5 times the length of the rod and a speed of 5 times the exit speed of the rod. In the case described, a maximum of 2 pulleys per set, for a total of 4 pulleys for the mobile crossmember, and 4 pulleys in the base, hence the ratio of 9. We also understand that the speed of movement of the elevator is equal to the speed of movement of the cylinder rod, also multiplied by the number of strands. In the example considered, this speed is therefore multiplied by 9.
Une autre réalisation selon l'invention figure 5 on peut distinguer un arrangement différent, avec le même principe de motorisation, sauf que l'extrémité du câble 50 monte tout en haut de la gaine, passe sur une ou (deux) poulie(s) de renvoi 51 et redescend sur un point de fixation 52 de la cabine 48 d'ascenseur. La cabine 48 étant plus lourde à vide, a tendance à descendre par gravitation, mais elle est maintenue par le câble 50. On comprend aisément que lorsque la tige du vérin 25 écarte le moufle, la cabine 48 part vers le haut et vis versa. Un avantage supplémentaire de la présente invention réside dans le fait que la quantité de liquide moteur est réduite en raison de la course réduite de la tige.Another embodiment according to the invention in FIG. 5 a different arrangement can be distinguished, with the same principle of motorization, except that the end of the cable 50 rises at the very top of the sheath, passes over one or (two) pulley (s) of return 51 and descends to a fixing point 52 of the elevator cabin 48. The cabin 48 being heavier when empty, tends to descend by gravitation, but it is held by the cable 50. It is easily understood that when the rod of the jack 25 moves the block away, the cabin 48 goes up and vice versa. An additional advantage of the present invention is that the amount of working fluid is reduced due to the reduced stroke of the rod.
La figure 6 représente une vue globale composée d'une traverse mobile 20 sur laquelle sont suspendus 2 tirants 15 au bout de ces tirants 15, 2 sets de poulies 10 entre les 2 sets de poulies 10 un corps de vérin 14 est fixé par le fond sur un socle 30 une tige de vérin 25 est fixée par son extrémité à la traverse mobile 20 et coulisse dans le corps du vérin 14. A l'angle du socle un point de fixation 34 des câbles est fixé. Dans la structure du socle 30, 4 poulies y sont installées dont une poulie 32 est en biais.FIG. 6 represents an overall view composed of a movable cross member 20 on which are hung 2 tie rods 15 at the end of these tie rods 15, 2 sets of pulleys 10 between the 2 sets of pulleys 10 a jack body 14 is fixed by the bottom on a base 30 a jack rod 25 is fixed at its end to the movable cross member 20 and slides in the body of the jack 14. A the angle of the base a fixing point 34 of the cables is fixed. In the structure of the base 30, 4 pulleys are installed there, a pulley 32 is biased.
- la traverse mobile 20 se déplace au minimum 5 fois moins vite que la cabine ou 9 fois au maximum.- the movable cross member 20 moves at least 5 times slower than the cabin or 9 times at most.
-la traverse mobile 20 se déplace au minimum 5 fois moins que la distance parcourue par la cabine 48 ou 9 fois au maximum suivant le nombre de poulies choisi. -la traverse mobile 20 se déplace, vers le haut et écarte ainsi le moufle, celui-ci tire sur le câble 40, qui est fixé sur le point de fixation 46 du contrepoids 42 qui l'entraîne vers le bas et par conséquent fait monter la cabine 48.the movable cross member 20 moves at least 5 times less than the distance traveled by the cabin 48 or at most 9 times depending on the number of pulleys chosen. the movable cross member 20 moves upwards and thus draws aside the block, the latter pulls on the cable 40, which is fixed on the fixing point 46 of the counterweight 42 which drives it downwards and consequently causes it to rise cabin 48.
-la traverse mobile 20 se déplace, vers le haut et écarte ainsi le moufle, celui-ci tire sur le câble 50, qui est fixé sur le point de fixation 52 de la cabine 48 qui l'entraîne vers le haut et par conséquent fait descendre le contrepoids 42.-the movable cross member 20 moves upward and thus spreads the block, which pulls on the cable 50, which is fixed on the fixing point 52 of the cabin 48 which drives it upwards and therefore makes lower the counterweight 42.
-la traverse mobile 20 supporte en pendentif les deux sets de poulies 10, qui se trouvent en dessous de la cabine 43 lorsque celle-ci est au point bas de sa position. the movable cross member 20 supports as a pendant the two sets of pulleys 10, which are located below the cabin 43 when the latter is at the lowest point of its position.
