Abstract

The trailer comprises a chassis with several wheels and two trays (30,32) installed symmetrically to the longitudinal plane of symmetry. There are means for measuring the possible inclination of the chassis about its longitudinal axis (XX'). There are liquid supply pipes (60,68,70) to the trays and sensors (38a,38b) for controlling the quantity of liquid in each tray as a function of the inclination measurement so that the quantity of liquid contained in each tray creates a return couple relative to the longitudinal axis to compensate for the possible inclination of the trailer.

Description

La présente invention a pour objet une remorque de train suiveur pour tunnelier.The present invention relates to a train trailer follower 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 also of significant length, we use the most often a machine called a tunnel boring machine for drilling the entire cutting face. The TBM itself is equipped with a follower train consisting of trailers in the form of wagons towed by the TBM. These trailers are used on the one hand to transport a certain number of elements necessary for the realization of the tunnel as and measurement of its drilling such as the segments that are set up for support the tunnel wall and on the other hand to the evacuation of the excavated material of the action of the TBM 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 interposition of rails guide. It is understood that, if the loading of the trailer is not symmetrical about its longitudinal plane or if the tunnel has in a horizontal plane a certain curvature, the wheels of the trailers who are not guiding are going to make the whole trailer take a certain inclination which, of course, needs to be corrected. Indeed, we understands that for its correct use, it is necessary that the trailers of the following train are substantially horizontal in particular to ensure the transfer in satisfactory conditions of the cuttings extracted by the TBM.

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 which keeps the trailer of the following train substantially horizontal while being of a simple technique and 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 tunnel boring follower that meets the conditions set out 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 train trailer comprising a chassis provided with a plurality of wheels defining a direction of advance 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 tanks mounted on the chassis substantially symmetrically with respect to the longitudinal plane of symmetry of the chassis;
  • means for measuring a possible inclination of the chassis of the trailer with respect to the horizontal about its longitudinal axis;
  • means for supplying liquid to the two tanks; and
  • means for controlling the quantity of liquid in each container as a function of the possible tilt measurement, so that the quantity of liquid contained in each container creates a return torque with respect to the longitudinal axis tending to compensate for the possible tilting 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 constantly monitoring the mass of liquid in each of the two side trays of the trailer, it is possible create a recall torque according to the indications of the inclinometer with which the trailer is fitted in order to create a return torque which 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 the wheels under the effect of the return torque. We also understand that this system has no complex components but simply the liquid storage receptacles and solenoid valve systems controlled by a central unit to adjust 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 filling the two tanks in a controlled manner is the one used to supply the cooling system of the TBM 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 double function of cooling the TBM and on the other hand to allow the creation of the booster couple ensuring the substantially horizontal maintenance of 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 essentially consists of a chassis 12 having a horizontal longitudinal axis XX 'and a vertical median plane at rest PP '. The chassis 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 of the 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 from 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 regards the present invention, it is not necessary to describe in more detail how the chassis 12 of the trailer is produced by the equipment it includes, in particular for the transfer and handling of segments.

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 symmetrically mounted relative to the longitudinal axis XX 'of the trailer. The bins are arranged along the external longitudinal edges 34 and 36 of the chassis of the trailer. For example each bin has a general shape rectangular parallelepiped and has a capacity of 1,500 liters. Each tank 30 and 32 is preferably equipped with a sensor 38a and 38b of measurement of the liquid level in tanks 30 and 32. In addition, a inclinometer identified by the reference 40 equips the upper part 22 of the trailer of the following train to provide a signal S representative of possible tilting 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 suitable quantity of 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 tanks 30 and 32 are half filled with 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 first to Figure 4, we will describe a simplified embodiment of the liquid supply circuits of the tanks 30 and 32. In this figure, there is shown a processing unit 42 which receives the signal d inclination S delivered by the inclinometer 40 and the signals N 1 and N 2 delivered by the level sensors 38a and 38b mounted in the tanks 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 correct 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 water arrives via main line 44. This pipe 44 supplies an input 30a and 32a respectively of the tanks 30 and 32 by solenoid valves 48 and 50. The tanks 30 and 32 include also an outlet opening 30b, 32b which is respectively connected to outlet lines 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 tilt information S, the central unit 42 calculates a level difference N 1 and N 2 to produce the restoring torque and this level difference is used to control the solenoid valves 48 and 50 for filling or the solenoid valves 56 and 58 for emptying the tanks in order 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.In Figure 5, there is shown an exemplary embodiment improved supply circuits for tanks 30 and 32 which provide less partly the cooling of the liquid circulating in the exchanger tunnel boring machine. In this embodiment, the tanks 30 and 32 therefore serve, as already explained, by the mass difference of liquid they contain, to create the booster couple and they serve also heat exchangers to cool at least partially the TBM coolant. In this circuit, we find in complement a pump 46 whose inlet 46a is connected to a first pipe 60 opening into outlet orifices 30c, 32c of tanks 30 and 32 via solenoid valves 62 and 64. The outlet 46b of the pump 46 is connected to a supply line 66 of the R cooling of the TBM. Each bin 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. Lines 70 and 68 are equipped with solenoid valves 74 and 76. The outlet pipe 78 of the circuit cooling system R of the TBM is connected by lines 80, 82 and 84 to a second inlet port 30e and 32e of tanks 30 and 32. The line 80 is fitted with a temperature sensor 86 and the lines 82 and 84 are fitted with a first single-pass solenoid valve 88 and a three-way solenoid valve 90. The solenoid valve 90 is also used for control an outlet flow rate in the pipe 92 leading to the outside of the trailer to serve as a general exit line from the 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 serve to control 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 be said in general that, when the temperature of the liquid coming from the exchanger of the tunnel boring machine via the pipe 78 is lower than a predetermined value T R , it is this liquid which will be used to fill tanks 30 and 32 in order to create the return torque. On the other hand, if the measured temperature T is higher than the reference temperature T R , the cold liquid arriving via line 72 will be used to adjust 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.We will now describe the operation of the hydraulic circuit shown in FIG. 5. When the temperature of the liquid leaving the tunnel machine 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 so 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 coming 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 difference in level N 1 and N 2 in the tanks creating the return torque while allowing a suitable flow of liquid in tanks 30 and 32 to cool the liquid circulating in the tunnel boring machine 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 tunnel boring machine measured by the sensor 86 is higher than T R , the central unit 42 controls the closing of the solenoid valve 88 and the communication of the line 82 with the line of outlet 92 by the valve 90. In this configuration, the liquid leaving the exchanger R of the tunnel boring 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 flows in the tanks are adjusted in such a way that the pump 46 can supply the exchanger of the tunnel boring machine 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 inclination measurement carried out by the sensor 40. These flow rates are regulated by the control of the solenoid valves 74, 76 and 62 and 64. The pipes r shown in FIG. 5 are also identified 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 tanks respectively on the right and on the left being ordered globally as are trays 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.Neither would one depart from the invention if the adjustment of the masses of liquid present in the tanks or arranged respectively right and left of the trailer chassis was not done using level measurement devices in these tanks but using measurement of debt. In this case, flow sensors could be mounted on the lines, respectively of inlet and outlet of the tanks, to ensure a differential flow in the tilt correction phases then at a zero differential flow when the tilt correction is obtained, the flow absolute then being adjusted so as to supply adequately the TBM heat exchanger.

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 described above preferably the head trailer, the coupling between the trailers is such that the return torque created by tanks 30 and 32 of the lead trailer is transmitted to the other trailers.
