Description

La présente invention a pour objet une remorque de train suiveur pour tunnelier.The present invention relates to a train trailer tracker for tunnel boring machine.

On sait que, pour la réalisation de tunnels de dimensions importantes et de longueur importante également, on utilise le plus souvent une machine appelée tunnelier permettant de forer l'ensemble du front de taille. Le tunnelier proprement dit est équipé d'un train suiveur constitué par des remorques ayant la forme de wagonnets tractés par le tunnelier. Ces remorques servent d'une part au transport d'un certain nombre d'éléments nécessaires à la réalisation du tunnel au fur et à mesure de son forage tels que les voussoirs qui sont mis en place pour étayer la paroi du tunnel et d'autre part à l'évacuation des déblais résultant de l'action du tunnelier proprement dit.We know that for the realization of tunnels of dimensions Important and important lengths, we use the most often a machine called tunnel boring machine to drill the entire cutting face. The tunnel boring machine itself is equipped with a follower train consisting of trailers in the form of wagons towed by the TBM. These trailers serve on the one hand to transport a certain number of elements needed to build the tunnel as and when measure of its drilling such as the voussoirs that are set up for support the tunnel wall and, on the other hand, the evacuation of the action of the tunnel boring machine itself.

Ces remorques équipées de roues se déplacent directement en reposant sur la paroi cylindrique du tunnel sans interposition de rails de guidage. On comprend que, si le chargement de la remorque n'est pas symétrique par rapport à son plan longitudinal ou si le tunnel présente dans un plan horizontal une certaine courbure, les roues des remorques qui ne sont pas directrices vont faire prendre à l'ensemble de la remorque une certaine inclinaison qu'il y a bien sûr lieu de corriger. En effet, on comprend que pour son utilisation correcte, il est nécessaire que les remorques du train suiveur soient sensiblement horizontales notamment pour assurer le transfert dans des conditions satisfaisantes des déblais extraits par le tunnelier.These trailers equipped with wheels move directly in resting on the cylindrical wall of the tunnel without the interposition of guide. We understand that, if the loading of the trailer is not symmetrical with respect to its longitudinal plane or if the tunnel presents in a horizontal plane a certain curvature, the wheels of the trailers who are not steered are going to get the entire trailer a certain inclination that there is of course place to correct. Indeed, we understands that for its correct use it is necessary that trailers of the follower train are substantially horizontal in particular to ensure the transfer in satisfactory conditions of the excavated extracted by the tunnel boring machine.

Il existe donc un réel besoin de disposer d'un système qui permette de maintenir la remorque du train suiveur sensiblement horizontale tout en étant d'une technique et d'un mode d'action simple.There is therefore a real need to have a system that to keep the trailer of the follower train substantially horizontal while being of a technique and a simple mode of action.

Un objet de la présente invention est de fournir une remorque de train suiveur de tunnelier qui satisfasse aux conditions énoncées ci-dessus.An object of the present invention is to provide a trailer of a TBM trainer that meets the stated conditions above.

Pour atteindre ce but, selon l'invention, la remorque de train suiveur de tunnelier comprenant un châssis muni d'une pluralité de roues définissant une direction d'avance de la remorque, ledit châssis présentant, au repos, un plan longitudinal vertical de symétrie et un axe longitudinal, se caractérise en ce qu'elle comprend en outre :

  • au moins deux bacs montés sur le châssis sensiblement symétriquement par rapport au plan longitudinal de symétrie du châssis ;
  • des moyens pour mesurer une inclinaison éventuelle du châssis de la remorque par rapport à l'horizontale autour de son axe longitudinal ;
  • des moyens d'alimentation en liquide des deux bacs ; et
  • des moyens pour commander la quantité de liquide dans chaque bac en fonction de la mesure d'inclinaison éventuelle, de telle manière que la quantité de liquide contenue dans chaque bac crée un couple de rappel par rapport à l'axe longitudinal tendant à compenser l'inclinaison éventuelle de ladite remorque.
To achieve this object, according to the invention, the tunneling follower trailer comprises a chassis provided with a plurality of wheels defining a direction of travel of the trailer, said chassis having, at rest, a vertical longitudinal plane of symmetry. and a longitudinal axis, is characterized in that it further comprises:
  • at least two bins mounted on the frame substantially symmetrically with respect to the longitudinal plane of symmetry of the frame;
  • means for measuring an eventual inclination of the frame of the trailer relative to the horizontal about its longitudinal axis;
  • means for supplying the two tanks with liquid; and
  • means for controlling the quantity of liquid in each tank according to the possible inclination measurement, such that the quantity of liquid contained in each tank creates a restoring torque with respect to the longitudinal axis tending to compensate for the possible inclination of said trailer.

On comprend qu'en contrôlant en permanence la masse de liquide dans chacun des deux bacs latéraux de la remorque, il est possible de créer un couple de rappel en fonction des indications de l'inclinomètre dont est équipée la remorque afin de créer un couple de rappel qui permet progressivement, durant l'avancée de la remorque, de ramener celle-ci dans une position sensiblement horizontale. Le retour du châssis de la remorque en position horizontale est obtenu par glissement latéral des roues sous l'effet du couple de rappel. On comprend également que ce système ne comporte aucun composant complexe mais simplement les bacs de réception de stockage du liquide et des systèmes d'électrovannes commandés par une unité centrale afin de régler le volume de liquide contenu dans chacun des deux bacs.We understand that by continuously monitoring the mass of fluid in each of the two side bins of the trailer, it is possible to create a restoring torque according to the indications of the inclinometer the trailer is equipped to create a recall torque that allows gradually, during the advance of the trailer, to bring it back in a substantially horizontal position. The return of the chassis of the trailer in horizontal position is obtained by lateral sliding of wheels under the effect of the return torque. We also understand that system has no complex components but simply the receiving bins for storing liquid and solenoid valve systems controlled by a central unit to regulate the volume of liquid contained in each of the two bins.

Selon un mode préféré de mise en oeuvre, le liquide utilisé pour remplir de façon contrôlée les deux bacs est celui qui sert à alimenter le circuit de refroidissement du tunnelier lui-même.According to a preferred embodiment, the liquid used for fill the two bins in a controlled way is the one used to feed the cooling system of the tunnel boring machine itself.

On comprend que, dans ce mode de réalisation, le liquide utilisé remplit la double fonction d'assurer le refroidissement du tunnelier et d'autre part de permettre la création du couple de rappel assurant le maintien sensiblement horizontal de la remorque du train suiveur de tunnelier.It is understood that, in this embodiment, the liquid used fulfills the dual function of cooling the tunnel boring machine and secondly to allow the creation of the return torque ensuring the keeping the trailer of the following train TBM.

En se référant tout d'abord aux figures 1 à 3, on va décrire un mode préféré de réalisation de la remorque de train suiveur de tunnelier.Referring first to Figures 1 to 3, we will describe a preferred embodiment of the tunneling follower train trailer.

La remorque est essentiellement constituée d'un châssis 12 présentant un axe longitudinal horizontal XX' et un plan médian vertical au repos PP'. Le châssis 12 est équipé à son extrémité inférieure d'une pluralité de roues ou de préférence de paires de roues ou galets tels que 14, 16 et 18 qui permettent à la remorque 10 de se déplacer sur la paroi cylindrique du tunnel 20.The trailer consists essentially of a chassis 12 having a horizontal longitudinal axis XX 'and a vertical median plane at PP 'rest. The frame 12 is equipped at its lower end with a plurality of wheels or preferably pairs of wheels or rollers such as 14, 16 and 18 which allow the trailer 10 to move on the wall cylindrical tunnel 20.

A sa partie supérieure 22, le châssis 12 de la remorque est équipé notamment d'un convoyeur 24 servant à transférer les déblais de l'extrémité avant 26 de la remorque jusqu'à son extrémité arrière 28.At its upper part 22, the chassis 12 of the trailer is equipped in particular with a conveyor 24 used to transfer the cuttings of the front end 26 of the trailer to its rear end 28.

Pour ce qui concerne la présente invention, il n'est pas nécessaire de décrire plus en détail la façon dont le châssis 12 de la remorque est réalisé par les équipements qu'il comporte notamment pour le transfert et la manipulation des voussoirs.As far as the present invention is concerned, it is not necessary to describe in more detail how the chassis 12 of the trailer is carried out by the equipment it includes in particular for the transfer and manipulation of the voussoirs.

A sa partie supérieure 22, la remorque est équipée de deux bacs 30 et 32 de préférence identiques et montés symétriquement par rapport à l'axe longitudinal XX' de la remorque. Les bacs sont disposés selon les bords longitudinaux externes 34 et 36 du châssis de la remorque. Par exemple chaque bac a une forme générale parallélépipédique rectangle et présente une capacité de 1 500 litres. Chaque bac 30 et 32 est de préférence équipé d'un capteur 38a et 38b de mesure du niveau de liquide dans les bacs 30 et 32. En outre, un inclinomètre repéré par la référence 40 équipe la partie supérieure 22 de la remorque du train suiveur pour fournir un signal S représentatif de l'éventuelle inclinaison de la remorque. At its upper part 22, the trailer is equipped with two tanks 30 and 32 preferably identical and mounted symmetrically relative to the longitudinal axis XX 'of the trailer. The bins are disposed along the outer longitudinal edges 34 and 36 of the chassis of the trailer. For example each tray has a general shape parallelepiped rectangular and has a capacity of 1500 liters. Each tray 30 and 32 is preferably equipped with a sensor 38a and 38b of measuring the level of liquid in the tanks 30 and 32. In addition, a inclinometer spotted by the reference 40 equips the top 22 of the trailer of the follower train to provide a signal S representative of the possible inclination of the trailer.

On comprend que selon le principe de la présente invention, les deux bacs 30 et 32 sont remplis chacun d'une quantité d'eau convenable permettant de créer un couple de rappel pour compenser l'inclinaison de la remorque mesurée par l'inclinomètre 40. Bien sûr au repos, c'est-à-dire lorsque la remorque a un plan médian PP' qui est vertical, les bacs 30 et 32 sont remplis de liquide à moitié.It is understood that according to the principle of the present invention, the two tanks 30 and 32 are each filled with a quantity of suitable water to create a return torque to compensate for the inclination of the trailer measured by the inclinometer 40. Of course at rest, that is to say when the trailer has a median plane PP 'which is vertical, the bins 30 and 32 are filled with half liquid.

En se référant tout d'abord à la figure 4, on va décrire un mode simplifié de réalisation des circuits d'alimentation en liquide des bacs 30 et 32. Sur cette figure, on a représenté une unité de traitement 42 qui reçoit le signal d'inclinaison S délivré par l'inclinomètre 40 et les signaux N1 et N2 délivrés par les capteurs de niveau 38a et 38b montés dans les bacs 30 et 32. En fonction de l'inclinaison mesurée, l'unité centrale 42 va gérer les niveaux de liquide N1 et N2 dans les deux bacs pour réaliser le couple de rappel convenable.Referring firstly to FIG. 4, a simplified embodiment of the liquid supply circuits of the containers 30 and 32 will be described. In this figure, a processing unit 42 is shown which receives the signal from S inclination delivered by the inclinometer 40 and N 1 and N 2 signals delivered by the level sensors 38a and 38b mounted in the bins 30 and 32. Depending on the inclination measured, the central unit 42 will manage the liquid levels N 1 and N 2 in the two tanks to achieve the appropriate return torque.

Dans ce mode de réalisation simplifié, le liquide qui est de préférence de l'eau arrive par la canalisation principale 44. Cette conduite 44 alimente une entrée 30a et 32a respectivement des bacs 30 et 32 par l'intermédiaire d'électrovannes 48 et 50. Les bacs 30 et 32 comportent également une ouverture de sortie 30b, 32b qui est respectivement raccordée à des conduites de sortie 52 et 54 équipées chacune d'une électrovanne 56 et 58.In this simplified embodiment, the liquid which is Preferably, the water arrives through main line 44. This pipe 44 feeds an inlet 30a and 32a respectively tanks 30 and 32 by via solenoid valves 48 and 50. Trays 30 and 32 comprise also an exit aperture 30b, 32b which is respectively connected to outlet pipes 52 and 54 each equipped with a solenoid valve 56 and 58.

On comprend que dans ce mode de réalisation simplifié, à partir de l'information S d'inclinaison, l'unité centrale 42 calcule une différence de niveau N1 et N2 pour réaliser le couple de rappel et cette différence de niveau sert à commander les électrovannes 48 et 50 de remplissage ou les électrovannes 56 et 58 de vidange des bacs pour adapter chaque niveau à la différence de niveaux souhaitée correspondant à la différence de masse convenable dans les bacs 30 et 32 pour produire le couple de rappel.It is understood that in this simplified embodiment, from the inclination information S, the central unit 42 calculates a level difference N 1 and N 2 to achieve the return torque and this level difference is used to control the solenoid valves 48 and 50 or the solenoid valves 56 and 58 for emptying the tanks to adapt each level to the desired level difference corresponding to the appropriate mass difference in the tanks 30 and 32 to produce the return torque.

Sur la figure 5, on a représenté un exemple de réalisation perfectionné des circuits d'alimentation des bacs 30 et 32 qui assurent au moins en partie le refroidissement du liquide circulant dans l'échangeur thermique du tunnelier. Dans ce mode de réalisation, les bacs 30 et 32 servent donc, comme on l'a déjà expliqué, par la différence de masse de liquide qu'ils contiennent, à créer le couple de rappel et ils servent également d'échangeurs de chaleur pour refroidir au moins en partie le liquide de refroidissement du tunnelier. Dans ce circuit, on trouve en complément une pompe 46 dont l'entrée 46a est raccordée à une première conduite 60 débouchant dans des orifices de sortie 30c, 32c des bacs 30 et 32 par l'intermédiaire d'électrovannes 62 et 64. La sortie 46b de la pompe 46 est raccordée à une conduite 66 d'alimentation du circuit de refroidissement R du tunnelier. Chaque bac comporte également une première entrée de liquide 30d, 32d qui est raccordée par les conduites 68, 70 et 72 à une source externe de liquide froid. Les conduites 70 et 68 sont équipées d'électrovannes 74 et 76. La conduite de sortie 78 du circuit de refroidissement R du tunnelier est raccordée par les conduites 80, 82 et 84 à un deuxième orifice d'entrée 30e et 32e des bacs 30 et 32. La conduite 80 est équipée d'un capteur de température 86 et les conduites 82 et 84 sont équipées d'une première électrovanne 88 à simple passage et d'une électrovanne 90 à trois voies. L'électrovanne 90 sert également à commander un débit de sortie dans la conduite 92 débouchant à l'extérieur de la remorque pour servir de conduite générale de sortie du liquide.FIG. 5 shows an exemplary embodiment improved feed circuits of the tanks 30 and 32 which ensure the less in part the cooling of the liquid circulating in the exchanger thermal tunneling tunnel. In this embodiment, the bins 30 and 32 serve, as already explained, by the difference in the mass of liquid they contain, to create the booster torque and they serve also heat exchangers to cool at least in part the Tunnel coolant. In this circuit, we find in complement a pump 46 whose input 46a is connected to a first conduit 60 opening into the outlet orifices 30c, 32c of the tanks 30 and 32 via solenoid valves 62 and 64. The output 46b of the pump 46 is connected to a pipe 66 for supplying the circuit of R cooling of the TBM. Each tray also has a first liquid inlet 30d, 32d which is connected by the pipes 68, 70 and 72 to an external source of cold liquid. Conduits 70 and 68 are equipped with solenoid valves 74 and 76. The outlet pipe 78 of the circuit the cooling tunnel R is connected via lines 80, 82 and 84 to a second inlet 30th and 32nd of the tanks 30 and 32. The pipe 80 is equipped with a temperature sensor 86 and the pipes 82 and 84 are equipped with a first solenoid valve 88 single pass and a solenoid valve 90 with three channels. Solenoid valve 90 is also used to control an output flow in the pipe 92 leading to the outside of the trailer to serve as the general driving liquid.

En outre, les bacs 30 et 32 sont équipés des capteurs de niveau 38a et 38b et la remorque est équipée de son inclinomètre 40. On retrouve également une unité centrale de gestion 42 qui reçoit sur ses entrées le signal S délivré par l'inclinomètre 40, la mesure de température T délivrée par le capteur de température 86 et les mesures de niveau N1 et N2 délivrées par les capteurs de niveau 38a et 38b des bacs 30 et 32. Les sorties de l'unité centrale de gestion 42 servent à commander les électrovannes 62, 64, 74, 76 et 88 et 90. L'unité centrale sert également à commander le circuit de commande 94 de la pompe 46.In addition, the tanks 30 and 32 are equipped with level sensors 38a and 38b and the trailer is equipped with its inclinometer 40. There is also a central management unit 42 which receives on its inputs the signal S delivered by the inclinometer 40 , the temperature measurement T delivered by the temperature sensor 86 and the level measurements N 1 and N 2 delivered by the level sensors 38a and 38b of the tanks 30 and 32. The outputs of the central management unit 42 are used to controlling the solenoid valves 62, 64, 74, 76 and 88 and 90. The central unit also serves to control the control circuit 94 of the pump 46.

Avant de décrire en détail le fonctionnement du circuit de liquide, on peut dire d'une manière générale que, lorsque la température du liquide provenant de l'échangeur du tunnelier par la conduite 78 est inférieure à une valeur prédéterminée TR, c'est ce liquide qui sera utilisé pour remplir les bacs 30 et 32 afin de créer le couple de rappel. En revanche, si la température mesurée T est supérieure à la température de référence TR, on utilisera le liquide froid arrivant par la conduite 72 pour régler les niveaux N1 et N2 de liquide dans les bacs 30 et 32.Before describing in detail the operation of the liquid circuit, it can generally be said that, when the temperature of the liquid coming from the tunnel-binder exchanger via line 78 is less than a predetermined value T R , it is this liquid will be used to fill the tanks 30 and 32 to create the return torque. On the other hand, if the measured temperature T is greater than the reference temperature T R , the cold liquid arriving via the pipe 72 will be used to regulate the levels N 1 and N 2 of liquid in the tanks 30 and 32.

Par exemple, la température de référence TR est égale à 40°C. For example, the reference temperature T R is equal to 40 ° C.

On va maintenant décrire le fonctionnement du circuit hydraulique représenté sur la figure 5. Lorsque la température du liquide sortant de l'échangeur du tunnelier mesurée par le capteur 86 est inférieure à TR, l'unité centrale 42 commande l'ouverture de l'électrovanne 88 et commande l'électrovanne 90 de telle manière que l'entrée 30e du bac 30 soit raccordée à la conduite 80. Simultanément, les électrovannes 74 et 76 sont fermées pour interrompre le débit de liquide venant de la source froide via la conduite 72. En fonction des indications de l'inclinomètre 40, les électrovannes 88, 90 et 62 et 64 sont commandées pour maintenir une différence de niveau N1 et N2 dans les bacs créant le couple de rappel tout en autorisant un débit convenable de liquide dans les bacs 30 et 32 pour assurer le refroidissement du liquide circulant dans l'échangeur du tunnelier. Cette circulation est obtenue grâce à la présence de la pompe 46.The operation of the hydraulic circuit shown in FIG. 5 will now be described. When the temperature of the liquid leaving the tunnel-binder exchanger measured by the sensor 86 is less than T R , the central unit 42 controls the opening of the solenoid valve 88 and controls the solenoid valve 90 such that the inlet 30e of the tank 30 is connected to the pipe 80. Simultaneously, the solenoid valves 74 and 76 are closed to interrupt the flow of liquid from the cold source via the pipe 72 According to the indications of the inclinometer 40, the solenoid valves 88, 90 and 62 and 64 are controlled to maintain a level difference N 1 and N 2 in the tanks creating the return torque while allowing a suitable flow of liquid in the tanks 30 and 32 for cooling the liquid flowing in the tunnel borer exchanger. This circulation is obtained thanks to the presence of the pump 46.

Si la température du liquide sortant de l'échangeur R du tunnelier mesurée par le capteur 86 est supérieure à TR, l'unité centrale 42 commande la fermeture de l'électrovanne 88 et la mise en communication de la conduite 82 avec la conduite de sortie 92 par la vanne 90. Dans cette configuration, le liquide sortant de l'échangeur R du tunnelier sort directement par la conduite de sortie 92. Le réglage des niveaux N1 et N2 dans les bacs 30 et 32 sera alors obtenu à partir de la source d'alimentation en liquide froid reliée à la conduite 72. Les débits de liquide dans les bacs sont réglés de telle manière que la pompe 46 puisse assurer l'alimentation de l'échangeur du tunnelier R et que la différence de niveau convenable soit maintenue dans les bacs 30 et 32 pour assurer la création du couple de rappel correspondant à la mesure d'inclinaison réalisée par le capteur 40. Ces débits sont réglés par la commande des électrovannes 74, 76 et 62 et 64. Les conduites représentées sur la figure 5 sont également repérées sur les figures 1 à 3.If the temperature of the liquid leaving the exchanger R of the TBM measured by the sensor 86 is greater than T R , the central unit 42 controls the closure of the solenoid valve 88 and the communication of the pipe 82 with the pipe of output 92 by the valve 90. In this configuration, the liquid leaving the exchanger R of the tunneling machine leaves directly via the outlet pipe 92. The adjustment of the levels N 1 and N 2 in the tanks 30 and 32 will then be obtained from of the cold liquid supply source connected to the pipe 72. The liquid flow rates in the tanks are adjusted in such a way that the pump 46 can supply the tunneling machine heat exchanger R and that the appropriate level difference is maintained in the tanks 30 and 32 to ensure the creation of the return torque corresponding to the tilt measurement performed by the sensor 40. These flow rates are set by the control of the solenoid valves 74, 76 and 62 and 64. The conduits shown in FIG. 5 are also marked in FIGS. 1 to 3.

Il va de soi que l'on ne sortirait pas de l'invention si la remorque comportait plus de deux bacs répartis le long des bords longitudinaux 34 et 36 du châssis, ces bacs respectivement à droite et à gauche étant commandés globalement comme le sont les bacs 30 et 32.It goes without saying that we would not go out of the invention if the trailer had more than two bins distributed along the longitudinal edges 34 and 36 of the chassis, these trays respectively to the right and to the left being ordered globally as are bins 30 and 32.

On ne sortirait pas non plus de l'invention si le réglage des masses de liquide présentes dans les bacs ou disposées respectivement à droite et à gauche du châssis de la remorque ne se faisait pas à l'aide de dispositifs de mesure de niveau dans ces bacs mais à l'aide de mesure de débit. Dans ce cas, des capteurs de débit pourraient être montés sur les conduites, respectivement d'entrée et de sortie des bacs, pour assurer un débit différentiel dans les phases de correction d'inclinaison puis à un débit différentiel nul lorsque la correction d'inclinaison est obtenue, le débit absolu étant alors réglé de manière à alimenter convenablement l'échangeur de chaleur du tunnelier.We would not go beyond the invention if the setting of masses of liquid present in the tanks or arranged respectively right and left of the trailer frame was not done using of level measuring devices in these bins but using measuring of debt. In this case, flow sensors could be mounted on pipes, respectively inlet and outlet bins, to ensure a differential flow rate in the tilt correction phases then to a zero differential flow when the tilt correction is obtained, the flow rate absolute being then adjusted in order to feed properly the heat exchanger of the tunnel boring machine.

Le système de maintien d'horizontalité décrit précédemment équipe, de préférence, la remorque de tête, l'accouplement entre les remorques est tel que le couple de rappel créé par les bacs 30 et 32 de la remorque de tête soit transmis aux autres remorques.The horizontality maintenance system previously described team, preferably, the head trailer, mating between trailers is such that the recall torque created by the bins 30 and 32 of the head trailer to other trailers.
