Comme le montre la figure 1, l'installation selon l'invention, pour le franchissement vertical de la dénivelée d'un escalier d'eau entre un bief amont haut 1 et un bief aval bas 2 pour bateaux comporte essentiellement un ascenseur à bateaux 3 qui est verticalement mobile entre le niveau haut du bief amont et le niveau bas du bief aval.  As shown in Figure 1, the installation according to the invention, for the vertical crossing of the vertical drop of a water stairway between a high forebay 1 and a low downstream 2 for boats essentially comprises a boat lift 3 which is vertically mobile between the high level of the forebay and the low level of the tailbay.
L'ascenseur à bateaux 3 comprend un bac 5 de réception des bateaux et un système 6 de levage du bac. Ce système est un système à câbles et treuils adapté à des grandes courses. Les câbles sont indiqués sur les figures par la référence 8 et les treuils par la référence 9. Le système selon l'invention à câbles et treuils est conçu de façon à assurer toutes les fonctions de manœuvre et de sécurité sans qu'il soit nécessaire de prévoir un équilibrage par exemple par contrepoids.  The boat lift 3 comprises a ferry 5 and a tray 6 for lifting the ferry. This system is a cable system and winches suitable for large races. The cables are indicated in the figures by the reference 8 and the winches by the reference 9. The system according to the invention to cables and winches is designed to provide all the maneuvering and safety functions without the need to provide a balance for example by counterweight.
Conformément à l'invention, le bac 5 reste en permanence suspendu à ses câbles 8 aussi bien en manœuvre qu'en position amont et en position aval. Ainsi, aucun dispositif de verrouillage en position ni en niveau amont ni en niveau aval notamment, qui sont source de pannes ou de fausses alertes, notamment lorsqu'il s'agit de système de contrôle de position des verrous, n'est nécessaire. Il n'y a pas d'appui du bac dans sa position basse, sauf en position de maintenance quand le bac vient reposer sur le socle de l'ouvrage. Etant donné que les câbles s'enroulent seulement sur les treuils, il n'y qu'une fatigue minimale dans ces câbles. Le bac 5 suspendu en permanence à ces câbles 8 reste entièrement libre de se dilater/contracter sans interférence avec des appuis. Le positionnement du bac par rapport aux biefs se fait à chaque manœuvre par arrêt du bac au même niveau d'eau que celui du bief concerné. Cela permet de conserver le niveau nominal d'eau dans le bac sauf en conditions extrêmes, et donc de ne pas alourdir la masse d'eau à lever et cela évite d'avoir à faire des transferts d'eau entre le bac et les biefs avant d'ouvrir les portes. According to the invention, the tray 5 remains permanently suspended from its cables 8 both in operation in the upstream position and downstream position. Thus, no locking device in position nor in upstream or downstream level in particular, which are a source of breakdowns or false alarms, especially when it comes to locking position control system, is necessary. There is no support tray in its low position, except in the maintenance position when the tray comes to rest on the base of the book. Since the cables only wind on the winches, there is only minimal fatigue in these cables. The tray 5 permanently suspended from these cables 8 remains completely free to expand / contract without interference with supports. The positioning of the ferry in relation to the diversion bays is done at each maneuver by stopping the ferry at the same level of water as that of the reach in question. This makes it possible to maintain the nominal level of water in the tank except in extreme conditions, and therefore not to weigh down the body of water to be lifted and this avoids having to transfer water between the tank and the diversion bays. before opening the doors.
Comme le montre le schéma fonctionnel de la figure 1, le bac 5 comporte une porte amont 11 pourvue d'un dispositif antichocs amont 12 et une porte aval 13 pourvue de moyens antichocs aval 14. Le bief amont est équipé d'une porte extérieure amont 16 pourvue de moyens d'étanchéité amont 17 et, associés à cette porte, de dispositif antichocs extérieur amont 18. Le bief aval 2 comporte une porte extérieure 20 pourvue de moyens d'étanchéité 21 d'un dispositif antichocs 22.  As shown in the block diagram of Figure 1, the tray 5 comprises an upstream door 11 provided with an upstream shockproof device 12 and a downstream door 13 provided with anti-shock means downstream 14. The forebay is equipped with an upstream outer door 16 provided with upstream sealing means 17 and, associated with this door, upstream external shockproof device 18. The tailgate 2 comprises an outer door 20 provided with sealing means 21 of an anti-shock device 22.
Pour faciliter la compréhension de l'invention, on donnera ci-après certaines dimensions et paramètres pour une installation d'une hauteur de franchissement utile de 39 mètres et comportant un ascenseur à bateaux d'une longueur de 200 mètres.  To facilitate the understanding of the invention, hereinafter will be given certain dimensions and parameters for an installation with a useful clearance height of 39 meters and having a boat lift with a length of 200 meters.
En se reportant à la figure 2, on constate que l'ouvrage de génie-civil de l'ascenseur 3 comporte principalement une pluralité de piles ou pylônes en béton 25, dans le cas de l'exemple représenté douze piles de 61 mètres de hauteur au-dessus du niveau du sol et d'une section au sol de 10x2 mètres. Les fûts sont creux et sont réalisés par quatre voiles en béton d'épaisseur maximum de 40 centimètres à leurs bases. Les piles 25 sont réparties équitablement de part et d'autre de l'ouvrage. Parmi les piles de l'ouvrage, deux d'entre elles, notées 26, assurent le guidage transversal du bac comme on l'expliquera plus bas et sont en forme de T réalisé par exemple par imbrication de deux piles de 10x2 mètres. Chaque pile fonctionne indépendamment des autres. Dans le sens longitudinal, des poutres treillis métalliques 27 relient les piles. Ces poutres sont le support des treuils 9 et du plancher 29 surplombant le bac 5. Dans l'exemple représenté, leur portée est de 30 mètres, elles courent sur une longueur de 40 mètres et leur hauteur au centre est de 6 mètres. Elles ne sont pas encastrées en tête des piles, elles ne participent donc pas à la stabilité de l'ensemble de la structure en béton. Dans le sens transversal, les piles 25 face à face forment un portique. Elles sont reliées par trois traverses en béton (non représentées) de 21 mètres de portée. Ces traverses sont le support des poutres treillis métalliques 27. Pour protéger les treuils de l'environnement extérieur, une super-structure 32 couvre les treuils. Referring to FIG. 2, it can be seen that the civil engineering work of elevator 3 mainly comprises a plurality of concrete piers or pylons 25, in the case of the example represented twelve stacks of 61 meters in height. above ground level and a ground section of 10x2 meters. The drums are hollow and are made by four thick concrete sails maximum of 40 centimeters at their bases. The piles 25 are evenly distributed on both sides of the structure. Among the piles of the structure, two of them, noted 26, provide the transverse guidance of the tray as will be explained below and are T-shaped realized for example by nesting two piles of 10x2 meters. Each stack works independently of the others. In the longitudinal direction, metal lattice girders 27 connect the stacks. These beams are the support of the winches 9 and the floor 29 overlooking the tray 5. In the example shown, their range is 30 meters, they run over a length of 40 meters and their height in the center is 6 meters. They are not embedded in the head of the batteries, so they do not participate in the stability of the entire concrete structure. In the transverse direction, the face-to-face piles form a gantry. They are connected by three concrete sleepers (not shown) with a span of 21 meters. These sleepers are the support of the metal lattice girders 27. To protect the winches from the outside environment, a super-structure 32 covers the winches.
Les piles en béton 25 assurent la stabilité générale de l'ouvrage et sont encastrées en pied dans leurs fondations dans le sens transversal comme dans le sens longitudinal. Les piles en T 26 sont dimensionnées pour encaisser les efforts en situation de séisme. Dans le sens longitudinal, le bac 5 est en appui sur une pile 30 du pont canal du côté du bief amont 1 ou sur une pile d'extrémité 25 qui serait renforcée. Cette pile sera dimensionnée pour résister aux efforts transmis par le bac en situation de séisme.  The concrete piles 25 ensure the overall stability of the structure and are embedded in their foot in their foundations in the transverse direction as in the longitudinal direction. The T-cells 26 are dimensioned to withstand efforts in an earthquake situation. In the longitudinal direction, the tray 5 is supported on a stack 30 of the channel bridge on the side of the forebay 1 or on an end stack 25 which would be reinforced. This battery will be sized to withstand the forces transmitted by the tank in earthquake.
Concernant le bac 5 fermé à ses deux extrémités par exemple par des portes levantes 11, 13 et équipées des dispositifs antichocs intérieurs 12, 14 destinés à protéger les portes d'extrémité d'éventuels chocs avec un bateau, il peut avoir, dans le cas d'exemple, une longueur utile de 195 mètres pour une largeur utile de 12,5 mètres. La profondeur d'eau dans le bac sera constante et pourrait être égale à 4 mètres. Ce bac dont les dimensions sont uniquement données à titre d'exemple comme les dimensions des piles, contient 10600 m3 d'eau, soit une masse d'eau embarquée de 10600 tonnes. La masse du bac, avec tous ses équipements, y compris les câbles qui le supportent, est, dans ce cas d'exemple, évalué à 4400 tonnes. Ceci amène à une masse mobile totale de 15000 tonnes (masse du bac et équipements et eau embarquée) à manœuvrer sur 39 mètres de hauteur de la dénivelée de l'exemple de l'invention. Regarding the tank 5 closed at both ends for example by lifting doors 11, 13 and equipped with internal shock devices 12, 14 for protecting the end doors from possible shocks with a boat, it can have, in the case for example, a useful length of 195 meters for a useful width of 12.5 meters. The water depth in the tank will be constant and could be equal to 4 meters. This tank, the dimensions of which are only given as an example as the dimensions of the batteries, contains 10600 m 3 of water, ie an on-board water mass of 10600 tons. The mass of the tank, with all its equipment, including the cables that support it, is, in this case example, estimated at 4400 tons. This leads to a total moving mass of 15,000 tonnes (mass of the tank and equipment and on-board water) to maneuver over 39 meters height of the unevenness of the example of the invention.
Le bac est avantageusement une structure métallique mécano-s oudée en U et consiste dans le cas d'espèce, donné uniquement à titre d'exemple, en un platelage d'environ 200 mètres de long posé sur cinquante poutres transversales espacées tous les 4 mètres environ sur toute la longueur du bac. Le platelage est constitué d'une plaque de 14 millimètres d'épaisseur et d'une vingtaine d'augets 33 de section 300x300 millimètres. La longueur d'une poutre transversale 31 est de 19 mètres pour une hauteur de 2,5 mètres. Chaque extrémité 35 d'une poutre 31 est suspendue par deux câbles 8. Ainsi, comme évoqué plus haut, le bac 5 est suspendu quasiment en continu sur toute sa longueur par les câbles 8, dans le cas d'espèce donné à titre d'exemple, par 200 câbles, répartis en cinquante couples sur chacun des grands côtés du bac, avec un point de levage à peu près tous les 4 mètres. Les poutres transversales 31 sont reliées entre elles dans le sens longitudinal par deux poutres, une au niveau de chaque côté du bac de 1 et 2,5 mètres de hauteur chacune, ce qui permet, en cas de perte d'un point de levage, de conserver une bonne rigidité de la structure et à l'ouvrage de continuer à fonctionner.  The tray is advantageously a metallic structure or U-shaped and consists in this case, given solely by way of example, a decking of about 200 meters long on fifty transverse beams spaced every 4 meters about the entire length of the tank. The decking consists of a plate 14 millimeters thick and twenty buckets 33 300x300 millimeters section. The length of a transverse beam 31 is 19 meters for a height of 2.5 meters. Each end 35 of a beam 31 is suspended by two cables 8. Thus, as mentioned above, the tray 5 is suspended almost continuously along its length by the cables 8, in this case given as for example, 200 cables, divided into fifty pairs on each of the long sides of the tank, with a lifting point approximately every 4 meters. The transverse beams 31 are interconnected in the longitudinal direction by two beams, one at each side of the tray 1 and 2.5 meters in height each, which allows, in case of loss of a lifting point, to maintain a good rigidity of the structure and the work to continue to function.
Le bac est constamment suspendu à ces câbles. Mais il est prévu, en situation de maintenance particulière ou en des circonstances accidentelles, de pouvoir poser le bac plein sur le plancher de l'ouvrage sur des points d'appui situés au droit du côté des points d'attache des câbles. Le bac est ainsi sollicité de la même façon qu'il soit posé sur ces appuis ou suspendu à ces câbles, et cela permet de régler efficacement en position de repos les longueurs et tensions des câbles. Des lisses de guidage (non représentées) par exemple au nombre de huit, réparties en quatre unités sur chaque côté, garnissent les parois latérales intérieures du bac. Ces lisses permettent de guider le bateau lors de ses manœuvres d'entrée et de sortie et de protéger le bac. Elles ont pour dimensions par exemple 150 millimètres en largeur pour 150 millimètres en hauteur. Le bac est également équipé d'une multitude de bollards répartis sur ses bords. Ces bollards sont fixes. The tray is constantly suspended from these cables. But it is planned, in particular maintenance situation or in accidental circumstances, to be able to pose the full tank on the floor of the structure on points of support located at the right side of the cable attachment points. The tray is thus solicited in the same way that it is placed on these supports or suspended from these cables, and this makes it possible to effectively adjust the lengths and tensions of the cables in the rest position. Guide rails (not shown) for example eight in number, divided into four units on each side, cover the inner side walls of the tray. These rails are used to guide the boat during its entry and exit maneuvers and to protect the ferry. They have for dimensions for example 150 millimeters in width for 150 millimeters in height. The ferry is also equipped with a multitude of bollards distributed on its edges. These bollards are fixed.
Concernant les portes amont 11 et aval 13 du bac, elles sont embarquées par l'intermédiaire d'un système de verrouillage (non représenté), par les portes d'extrémité 16, 20 des biefs 1, 2 lors de la manœuvre de celles-ci. Ceci permet de s'affranchir d'un dispositif de manœuvre spécifique installé sur le bac qui alourdirait localement ce dernier. Pour ne pas surcharger les extrémités du bac, les portes comportent des caissons étanches remplaçant localement un volume d'eau par un volume d'air plus léger. Les bordés des portes d'extrémité du bac et des biefs sont positionnés de façon à réduire au maximum le volume d'eau mort entre celles-ci. Les portes sont équipées de galets ou patins de glissement frontaux et latéraux guidés dans des rails installés sur le bac.  As regards the upstream and downstream gates 13 of the ferry, they are loaded by means of a locking system (not shown), by the end gates 16, 20 of the bays 1, 2 during the maneuvering thereof. this. This makes it possible to dispense with a specific maneuvering device installed on the tank which would weigh down the latter locally. To avoid overloading the ends of the tank, the doors have watertight boxes replacing locally a volume of water by a lighter volume of air. The edges of the end doors of the tank and the reaches are positioned so as to minimize the volume of dead water between them. The doors are equipped with rollers or sliding skids frontal and lateral guided in rails installed on the tray.
Concernant les dispositifs antichocs aval 14 et amont 12 du bac qui peuvent être de différents types, la figure 9 illustre un de ces types de dispositifs antichocs d'extrémité aval 14. Ce dispositif nécessaire à l'extrémité aval du bac lorsque ce dernier est en position d'attente d'un bateau avalant, c'est-à-dire descendant, est indépendant du bac. Il est fixe et encastré dans l'ouvrage de génie-civil de l'ascenseur. En fin de phase d'ascension du bac, le dispositif de protection plonge dans le bac au fur et à mesure que ce dernier remonte, comme le montre la figure 9. A cette fin, le dispositif comporte une partie en forme de poutre 37 venant se situer à l'extérieur de la paroi frontale du bac et une partie tampon 38 située à l'intérieur du bac devant la paroi frontale, les deux parties formant un ensemble en forme d'un U renversé entre les branches duquel s'engage la paroi du bac. L'amortissement des chocs éventuels se fait par l'intermédiaire de défenses tronconiques 36. With regard to the downstream anti-shock devices 14 and upstream 12 of the container, which can be of different types, FIG. 9 illustrates one of these types of downstream end shock devices 14. This device is necessary at the downstream end of the container when the latter is in waiting position of a swallowing boat, that is to say descending, is independent of the ferry. It is fixed and recessed in the civil engineering work of the elevator. In end of the ascending phase of the tank, the protective device dives into the tank as it goes up, as shown in Figure 9. For this purpose, the device comprises a beam-shaped portion 37 coming from located outside the front wall of the tank and a buffer portion 38 located inside the tank in front of the front wall, the two parts forming an assembly in the form of a U inverted between the branches which engages the wall Tray. The damping of the possible shocks is done by means of frustoconical defenses 36.
Un dispositif antichocs amont 12 est nécessaire à l'extrémité amont du bac lorsque ce dernier est en position attente d'un bateau montant. Le dispositif peut être constitué d'une poutre "bouclier" 39 coulissant horizontalement au travers de la porte du bac. La poutre transfère directement l'énergie du choc sur un dispositif amortisseur tronconique 40 fixé sur l'ouvrage (figure 10) .  An upstream shockproof device 12 is necessary at the upstream end of the tank when the latter is in the waiting position of a rising boat. The device may consist of a beam "shield" 39 sliding horizontally through the door of the tray. The beam directly transfers the energy of the shock to a frustoconical damping device 40 fixed to the structure (FIG. 10).
Ainsi, les dispositifs antichocs permettent de transférer les efforts et l'énergie engendrés par le choc d'un bateau directement aux superstructures de l'ouvrage sans solliciter le bac lui-même. La disposition fixe des dispositifs amortisseurs limite au strict minimum la masse embarquée par le bac.  Thus, anti-shock devices can transfer the forces and energy generated by the impact of a boat directly to the superstructure of the work without soliciting the ferry itself. The fixed disposition of the damping devices limits to the strict minimum the mass embarked by the tray.
En se référant aux figures 4 à 6, on décrit ci- après le système de guidage longitudinal et transversal du bac.  With reference to FIGS. 4 to 6, the longitudinal and transverse guide system of the tray is described below.
Conformément à l'invention, pour éviter les mouvements du bac dans le plan horizontal et les chocs destructeurs qui en résulteraient compte tenu des masses en présence, celui-ci est plaqué, sous l'effet de son propre poids, sur l'ouvrage de génie-civil dans le sens longitudinal et transversal, par l'intermédiaire de dispositifs roulants ou glissants de guidage transversal 42 et longitudinal 43. Ceci permet de s'affranchir de l'intégration d'un mécanisme de précontrainte supplémentaire pour éliminer les jeux mécaniques dans les chariots. Le bac est guidé en trois points de façon à conserver le caractère isostatique de l'ensemble. Ainsi, le bac est en appui sur deux points dans le sens transversal et sur un point dans le sens longitudinal. Le guidage transversal est assuré par deux chariots 42 positionnés sur un des grands côtés du bac et le guidage longitudinal par un chariot 43 positionné en bout de bac côté amont, comme le montre la figure 6. Les chariots sont associés à des rails de guidage installés sur les piles de l'ouvrage. In accordance with the invention, to avoid the movements of the tray in the horizontal plane and the resulting destructive shocks given the masses present, it is plated, under the effect of its own weight, on the structure of civil engineering in the longitudinal and transverse direction, by means of rolling or sliding devices of transverse guide 42 and longitudinal 43. This eliminates the integration of a prestressing mechanism extra to eliminate the mechanical games in the trolleys. The tray is guided in three points so as to maintain the isostatic character of the whole. Thus, the tray is supported on two points in the transverse direction and on a point in the longitudinal direction. The transverse guidance is provided by two carriages 42 positioned on one of the long sides of the tray and the longitudinal guide by a carriage 43 positioned at the end of the tray upstream side, as shown in Figure 6. The carriages are associated with guide rails installed on the piles of the book.
Le principe du guidage transversal et longitudinal, qui vient d'être décrit, est assuré par l'inclinaison des câbles 8, de l'angle β pour créer une force d'application dans le sens transversal contre le pilier de butée 26 correspondant, comme le montre la flèche Ft de la figure 4, et de l'angle a créant une force agissant dans le sens longitudinal pour appliquer le chariot 43 contre le pilier de butée associé, illustré par la flèche Fl de la figure 5.  The principle of transverse and longitudinal guidance, which has just been described, is ensured by the inclination of the cables 8, the angle β to create a force of application in the transverse direction against the abutment abutment 26 corresponding, as shown by the arrow Ft of FIG. 4, and the angle α creating a force acting in the longitudinal direction to apply the carriage 43 against the associated abutment abutment, illustrated by the arrow F1 in FIG.
Ce système comporte seulement des treuils 9 et des câbles 8, sans contrepoids d'équilibrage notamment. Dans ce système, dans le cas d'espèce donné uniquement à titre d'exemple et impliquant une masse nominale à manœuvrer de 15000 tonnes et d'une hauteur du franchissement de 39 mètres, 100 treuils sont prévus pour manœuvrer les 15000 tonnes du bac. Ils sont répartis sur les 200 mètres de l'ouvrage en deux rangées de 50 de part et d'autre du bac. La figure 11 montre un treuil 9 avantageusement utilisable dans le cadre de l'invention. Ce treuil est pourvu de quatre moteurs-freins synchrone 45 qui entraînent en rotation, chacun par l'intermédiaire d'un pignon 47, une couronne dentée 48 solidaire en rotation du tambour 49 du treuil. Le tambour d'un grand diamètre d'enroulement permet l'enroulement de deux câbles 8 et présente un rainurage pour une seule couche d'enroulement. Toujours à titre d'exemple, la capacité nominale d ' un treuil dans le cas d' espèce est avantageusement de 160 tonnes, la capacité maximum admissible d'un treuil de 170 tonnes et la capacité nominale pour cent treuils de 16000 tonnes, chaque moteur a y a n t u n e p u i s s a n c e n o m i n a l e d e 45 Kw. This system comprises only winches 9 and 8 cables, without balancing counterweight in particular. In this system, in this case only given by way of example and involving a nominal weight to maneuver of 15000 tons and a height of the crossing of 39 meters, 100 winches are planned to maneuver the 15000 tons of the tank. They are spread over 200 meters of the structure in two rows of 50 on each side of the tank. Figure 11 shows a winch 9 advantageously used in the context of the invention. This winch is provided with four synchronous braking motors 45 which rotate, each through a pinion 47, a ring gear 48 integral in rotation with the drum 49 of the winch. The drum of a large winding diameter allows the winding of two cables 8 and has a groove for a single winding layer. Still as an example, the capacity In this case, the winch rating is advantageously 160 tons, the maximum permissible capacity of a winch of 170 tons and the nominal capacity per hundred winches of 16000 tons, each engine having a mechanical power of 45 Kw.
En fonctionnement normal, les quatre moteurs 45 à freins intégrés de chaque treuil 9 sont sollicités pour manœuvrer le bac 5. Ils sont utilisés en-deçà de leur capacité maximale . Ainsi, en cas de panne ou de maintenance d'un des quatre moteurs d'un treuil, les trois moteurs restants peuvent assurer la montée du bac à sa vitesse de manœuvre nominale. Cette grande redondance de moteur permet de maximiser la disponibilité de l'installation, ce qui est un gage de sécurité extrêmement important. Le système treuils/câbles est commandé en déplacement et la position en rotation des tambours de treuil est contrôlée en permanence. Les 100 treuils sont asservis de façon à contrôler en permanence le déplacement de chacun et de corriger en conséquence. Cette disposition permet de garantir l'horizontalité du plan d'eau du bac. Une correction en couple intervient lorsqu'une différence de charge entre les différents treuils atteint un certain seuil.  In normal operation, the four motors 45 with integrated brakes of each winch 9 are biased to maneuver the tray 5. They are used below their maximum capacity. Thus, in case of failure or maintenance of one of the four winch motors, the remaining three motors can ensure the rise of the tank at its nominal operating speed. This high engine redundancy makes it possible to maximize the availability of the installation, which is an extremely important security guarantee. The winch / rope system is controlled in motion and the rotational position of the winch drums is constantly monitored. The 100 winches are slaved to constantly monitor the movement of each and correct accordingly. This arrangement makes it possible to guarantee the horizontality of the body of water of the tank. A torque correction occurs when a load difference between the different winches reaches a certain threshold.
Le nombre de treuils aux extrémités du bac est doublé. Cette disposition répond à l'augmentation locale de la masse aux extrémités du bac du fait de l'intégration des équipements tels que les portes et les dispositifs antichocs. De plus, la perte d'un point de levage s'avère plus critique en extrémité qu'ailleurs en raison de la réduction du potentiel de répartition des efforts .  The number of winches at the ends of the tank is doubled. This arrangement responds to the local increase in the mass at the ends of the tray due to the integration of equipment such as doors and anti-shock devices. In addition, the loss of a lifting point is more critical at the end than elsewhere due to the reduction of the potential of distribution of efforts.
Il est à noter que l ' on contrôle de façon permanente le courant des moteurs et en cas de perte de courant, les treuils sont immédiatement arrêtés.  It should be noted that the motor current is permanently controlled and in the event of a loss of power, the winches are immediately stopped.
Etant donné que chaque treuil 9 est équipé ici de deux câbles 8, le système de levage comporte, dans l'exemple choisi, deux-cent câbles. La capacité nominale d'un câble est de 80 tonnes, pour une capacité maximum admissible de 85 tonnes. Ainsi la capacité maximum admissible pour le système de levage est de 17000 tonnes, soit 2000 tonnes de marge par rapport à la masse nominale à manœuvrer. Le coefficient de sécurité appliqué sur les câbles 8 de levage est de 5. Le nombre de treuils et de câbles installés offre une très grande redondance à l'ensemble, ce qui est un atout considérable du point de vue de la sécurité. Le fait que le bac est constamment suspendu à ces câbles assure que ceux-ci restent sous tension permanente, ce qui limite leur fatigue. Les attaches des câbles aux poutres du bac sont des rotules autorisant au besoin les variations d'inclinaison des câbles et de leur chape d'extrémité pendant les manœuvres. L'invention prévoit la possibilité d'équilibrer la charge entre deux câbles montés sur un même treuil. Pour cela, des ridoirs sont installés sur chaque câble. Lors de l'installation et des opérations de maintenance, on règle le ridoir en contrôlant la tension du câble à l'aide d'un outil de mesure, jusqu'à atteindre la même tension dans ces deux derniers. En cas d'incendie, un système déluge fournira une grande quantité d'eau sur chacun des câbles. Since each winch 9 is equipped here with two cables 8, the lifting system comprises, in the chosen example, two hundred cables. The nominal capacity of a cable is 80 tonnes, with a maximum capacity of 85 tonnes. Thus the maximum permissible capacity for the lifting system is 17000 tons, ie 2000 tons of margin compared to the nominal mass to maneuver. The safety factor applied on the lifting cables 8 is 5. The number of winches and cables installed provides a very high redundancy to the assembly, which is a considerable asset from the point of view of safety. The fact that the tray is constantly suspended from these cables ensures that they remain under permanent tension, which limits their fatigue. The cable ties to the bin girders are ball joints allowing, if necessary, variations in the inclination of the cables and their end cap during maneuvers. The invention provides the possibility of balancing the load between two cables mounted on the same winch. For this, turnbuckles are installed on each cable. During installation and maintenance operations, the turnbuckle is adjusted by checking the cable tension using a measuring tool, until the same voltage is reached in the latter two. In case of fire, a deluge system will provide a large amount of water on each of the cables.
La figure 12 illustre, à titre d'exemple, un câble particulièrement adapté pour être utilisé dans le cadre de l'invention. Ce câble par exemple d'un diamètre de 72 mm comprend huit torons extérieurs 49, six torons intermédiaires 50 et un toron central 51, chacun des torons étant constitué d'une pluralité de fils 52. Le câble comporte une infiltration plastique indiquée en 53 qui évite d'une manière efficace la destruction, les frottements et la corrosion intérieure.  Figure 12 illustrates, by way of example, a cable particularly suitable for use in the context of the invention. This cable, for example with a diameter of 72 mm, comprises eight outer strands 49, six intermediate strands 50 and one central strand 51, each of the strands consisting of a plurality of wires 52. The cable comprises a plastic infiltration indicated at 53 which effectively avoids destruction, friction and internal corrosion.
En se reportant aux figures 7 et 8, on décrira ci- après des équipements hydromécaniques du bief amont, à savoir la porte extérieure 16 de ce bief et le dispositif de protection antichocs extérieur 18. La porte extérieure amont 16 est une porte levante. Elle est manœuvrée par deux treuils de levage 55 chacun équipé d'un câble supportant la porte à ses deux extrémités. Pour sa translation verticale, la porte est équipée de galets ou de patins associés à des rails implantés dans l'ouvrage de génie-civil. Lors de sa manœuvre, la porte extérieure 16 embarque la porte amont 11 du bac 5 par l'intermédiaire d'un système de verrouillage (non représenté) . Referring to FIGS. 7 and 8, the following will be described hydromechanical equipment of the forebay, namely the outer door 16 of this reach and the outer shock protection device 18. The upstream outer door 16 is a lifting door. It is maneuvered by two lifting winches 55 each equipped with a cable supporting the door at both ends. For its vertical translation, the door is equipped with rollers or skids associated with rails installed in the civil engineering work. During its maneuver, the outer door 16 embeds the upstream door 11 of the tray 5 by means of a locking system (not shown).
Le dispositif de protection antichocs extérieur 18 permet de protéger la porte d'un éventuel choc avec un bateau. Ce dispositif est constitué d'une poutre bouclier 57 traversant le bief dans sa largeur. A chaque extrémité de cette poutre sont encastrés dans l'ouvrage des dispositifs amortisseurs 59 permettant d'absorber l'énergie du choc transféré par la poutre. Pour laisser passer les bateaux, la poutre s'efface par un mouvement de translation verticale. Cette translation est assurée par deux treuils de levage 61 non motorisés chacun équipé d'un câble supportant la poutre à ses deux extrémités. Les treuils sont actionnés en rotation par une liaison mécanique 63 les reliant au treuil moteur 55 correspondant du dispositif de manœuvre de la porte 16. Ainsi, le dispositif de protection est embarqué lors de la manœuvre de la porte. Le dispositif amortisseur étant fixé sur l'ouvrage, seule la porte et son bouclier sont manœuvrés. Cette disposition permet de limiter la masse à soulever par les treuils.  The outer shock protection device 18 can protect the door from any impact with a boat. This device consists of a shield beam 57 crossing the reach in its width. At each end of this beam are embedded in the structure damping devices 59 to absorb the energy of the shock transferred by the beam. To let the boats through, the beam is erased by a vertical translation movement. This translation is provided by two non-motorized lifting winches 61 each equipped with a cable supporting the beam at both ends thereof. The winches are actuated in rotation by a mechanical link 63 connecting them to the corresponding motor winch 55 of the operating device of the door 16. Thus, the protection device is embarked during the operation of the door. The damping device being fixed on the structure, only the door and its shield are maneuvered. This arrangement limits the mass to be lifted by the winches.
Le bief amont 1 est également équipé d'un dispositif de coupure en charge, qui est positionné en amont du pont canal faisant la liaison avec l'ascenseur à bateaux et permet d'éviter la vidange du bief en cas de fuite de la porte ou du pont canal de liaison.  The forebay 1 is also equipped with a load cut-off device, which is positioned upstream of the canal bridge linking with the boat lift and makes it possible to avoid the emptying of the reach in the event of a door leak. the connecting canal bridge.
Concernant les équipements hydromécaniques du bief aval 2, ils comprennent la porte extérieure aval 20, le dispositif de protection antichocs extérieur aval 22 et un dispositif de coupure de charge. Ces équipements peuvent être identiques aux équipements hydromécaniques du bief amont 1. Le dispositif de coupure en charge se justifie en cas de rupture de la porte extérieure aval 20. Dans une telle circonstance, le bief se déverserait au niveau du plancher de l'ascenseur. Regarding the hydro-mechanical equipment of the tailbay 2, they comprise the downstream outer door 20, the downstream external shock protection device 22 and a load-breaking device. This equipment may be identical to the hydromechanical equipment of the forebay 1. The cut-off device is justified in case of rupture of the downstream outer door 20. In such a circumstance, the reach would be discharged at the floor of the elevator.
Comme il ressort de la description qui vient d'être faite à titre d'exemple et se reportant à des figures représentant, uniquement à titre d'exemple un mode de réalisation de l'invention, l'installation selon l'invention présente de nombreux avantages. Ainsi, le bac 5 est supporté en continu sur toute sa longueur, avec des points de levage rapprochés de chaque côté du bac, ce qui permet d'éviter des tronçons autoporteurs de grande longueur et donc beaucoup plus lourds. Le dispositif de levage est un dispositif à câbles et treuils bien adaptés à des grandes courses, ce qui permet d'obtenir un ensemble léger et souple, tolérant à l'égard des précisions et des déformations des structures et des terrains, facile à régler et à entretenir et éprouvé. Le dispositif de levage ne nécessite pas d'équilibrage du bac par contrepoids. Ceci constitue entre autres une mesure de sécurité importante évitant que le bac puisse être emporté par les contrepoids lorsqu'il est accidentellement vidé en manœuvre. La masse d'eau représentant les deux tiers de la masse à lever, pour éviter ce phénomène et compte tenu des marges de sécurité, la masse de contrepoids installée ne pourrait pas dépasser environ 25% de la masse totale à lever sans ajout de dispositifs de sécurité de blocage du bac en position, puissants, complexes et coûteux. C'est trop peu pour justifier l'installation de contrepoids avec tous les équipements associés qu'il nécessite. Le gain énergétique par un équilibrage à seulement 25%, avec des contrepoids, serait secondaire alors que le coût d'investissement serait signif icativement majoré. De plus, à la descente du bac, de l'énergie électrique peut être récupérée par réinjection au réseau électrique. Concernant les contrepoids que l'invention évite d'utiliser, ils sont par définition lourds, difficiles et coûteux à transporter et à installer et à démonter. En évitant des contrepoids, l'invention permet d'éviter aussi des dispositifs associés aux contrepoids, qui sont nombreux et coûteux, à savoir des structures et mécanismes de guidage, des poulies de renvoi de grands diamètres et des mécanismes de levage lourds pour l'installation et le déchargement lorsqu'on a à changer les câbles. Les contrepoids nécessiteraient aussi de doubler les longueurs de câble de chaque suspension, ce qui pénaliserait le comportement dynamique vibratoire du système. De plus, les contrepoids surchargeraient très significativement la structure et les fondations de l'ouvrage tant en statique qu'en dynamique en cas de séisme notamment. As is apparent from the description which has just been given by way of example and referring to figures representing, by way of example only one embodiment of the invention, the installation according to the invention has many advantages. Thus, the tray 5 is supported continuously along its length, with lifting points close together on each side of the tray, which avoids self-supporting sections of great length and therefore much heavier. The lifting device is a cable and winch device well adapted to large races, which makes it possible to obtain a light and flexible assembly, tolerant with regard to the precisions and deformations of structures and terrain, easy to adjust and to maintain and tested. The lifting device does not require balancing of the tray by counterweight. This is, among other things, an important safety measure to prevent the tank can be carried by the counterweight when it is accidentally emptied in maneuver. As the body of water represents two-thirds of the mass to be lifted, to avoid this phenomenon and taking into account safety margins, the mass of counterweight installed could not exceed approximately 25% of the total mass to be lifted without the addition of safety devices. Locking security of the bin in position, powerful, complex and expensive. This is too little to justify the installation of counterweights with all the associated equipment that it requires. The energy gain by balancing at only 25%, with counterweights, would be secondary, whereas the investment cost would be significantly higher. In addition, the descent of the tank, electrical energy can be recovered by reinjection to the power grid. As for the counterweights that the invention avoids using, they are by definition heavy, difficult and expensive to transport and install and disassemble. By avoiding counterweights, the invention also makes it possible to avoid devices associated with counterweights, which are numerous and expensive, namely guiding structures and mechanisms, large diameter return pulleys and heavy lifting mechanisms for the counterweight. installation and unloading when you have to change the cables. Counterweights would also require doubling the cable lengths of each suspension, which would penalize the vibratory dynamic behavior of the system. In addition, the counterweights would significantly overload the structure and foundations of the structure both statically and dynamically in case of earthquake in particular.
Pendant une manœuvre, le bac est guidé transversalement et longitudinalement au moyen de dispositifs roulants ou glissants le long des pylônes structurants de l'ouvrage. Le bac est plaqué contre ces pylônes naturellement et gravitairement par une légère inclinaison des câbles de levage par rapport à la verticale. L'inclinaison est telle qu'elle "précontraint" le "placage" et interdit tout déplacement du bac dans le plan horizontal sous toute sollicitation dans ce plan (inertie, vent, etc.) et donc tout choc.  During a maneuver, the tank is guided transversely and longitudinally by means of rolling or sliding devices along the structuring pylons of the structure. The tray is pressed against these pylons naturally and gravitarily by a slight inclination of the lifting cables relative to the vertical. The inclination is such that it "prestressed" the "plating" and prohibits any movement of the tray in the horizontal plane under any stress in this plane (inertia, wind, etc.) and therefore any shock.
Concernant les principes de manœuvre avantageux, le bac reste en permanence suspendu à ces câbles aussi bien en manœuvre qu'en position amont ou en position aval. Il n'y a pas de verrouillage en position ni en amont ni en aval, il n'y a pas d'appui en bas sauf en position de maintenance quand le bac vient reposer sur le socle de l'ouvrage. Il n'y a que très peu de fatigue dans les câbles. Les treuils contrôlent tout en position, assurent tous les freinages et toutes les sécurités. Le bac suspendu en permanence à ces câbles reste entièrement libre de se dilater/contracter sans interférence avec les appuis. Le système de levage à câbles et treuils permet un positionnement du bac par rapport aux biefs à chaque manœuvre par arrêt du bac au même niveau d'eau que le bief concerné. Ceci permet de conserver le niveau nominal d'eau dans le bac et évite d'avoir à faire des transferts d'eau entre bac et bief avant d'ouvrir les portes. Tout comme les biefs amont et aval, le bac est fermé au plus près de ses extrémités par des portes levantes pour limiter le volume d'eau "entre portes" qui sera perdu à chaque manœuvre et représente quelques mètres cubes. Un masque mobile, mécanique ou pneumatique assure l'étanchéité entre bac et bief. L'accès à l'ouvrage par l'extérieur peut se faire indifféremment par le plateau du bief amont ou par celui du bief aval selon l'interprétation architecturale choisie. Un autre avantage que procure l'invention réside dans la vitesse de levage relativement élevée de l'ascenseur et globalement la rapidité du franchissement puisqu'il n'y a pas de transfert d'eau bief/bac ou verrouillage avec les temps d'attente correspondantes. Regarding the principles of maneuvering advantage, the tray remains permanently suspended from these cables both in maneuver in upstream position or in downstream position. There is no lock in position neither upstream nor downstream, there is no support down except in the maintenance position when the tray comes to rest on the base of the structure. There is very little fatigue in the cables. The winches control everything in position, ensure all braking and all safety. The tray permanently suspended from these cables remains entirely free to expand / contract without interference with the support. The hoisting system with cables and winches allows the tank to be positioned in relation to the diversion bays at each maneuver by stopping the tank at the same water level as the reach in question. This keeps the nominal level of water in the tank and avoids having to transfer water between tank and reach before opening the doors. Just as the upstream and downstream reaches, the tank is closed closer to its ends by lifting doors to limit the volume of water "between doors" that will be lost at each maneuver and represents a few cubic meters. A mobile, mechanical or pneumatic mask ensures the seal between tank and reach. Access to the structure from the outside can be done either by the plateau of the forebay or the downstream reach depending on the architectural interpretation chosen. Another advantage provided by the invention lies in the relatively high lifting speed of the elevator and generally the speed of crossing because there is no water transfer / tank or lock with waiting times corresponding.
Bien entendu, de multiples modifications peuvent être apportées à 1 ' invention sans sortir du cadre de l'invention telle que décrite. Les dimensions données pour faciliter la compréhension de l'invention n'ont été données qu'à titre d'exemple et peuvent être choisies différemment en fonction de chaque cas d'espèce.  Of course, multiple modifications can be made to the invention without departing from the scope of the invention as described. The dimensions given to facilitate understanding of the invention have been given by way of example and may be chosen differently depending on each particular case.
