This machine comprises a shield consisting of two mutually movable parts, a forward knife casing 1 supporting on its inside a digging device 3 and a rear assembly skirt 2 acting as a guide means for a thrust ring 10. The knife casing and the assembly skirt are mutually connected by a slack fastening system allowing them to pivot with respect to each other in such a manner that their longitudinal axes form an adjustable angle.

Description

L'invention concerne une machine perfectionnée pour la réalisation de galeries souterraines ; elle vise une machine permettant de creuser un boyau souterrain et de l'équiper progressivement, au fur et à mesure de l'avancement de la machine, d'éléments de revêtement soutenant les terres tels que tuyaux ou voussoirs.The invention relates to an improved machine for producing underground galleries; it aims at a machine making it possible to dig an underground hose and to progressively equip it, as the machine advances, with covering elements supporting the earth such as pipes or segments.

On connait déjà de telles machines qui sont essentiellement composées d'un bouclier hydraulique et d'un dispositif d'abattage logé à l'intérieur du bouclier. Le dispositif d'abattage, généralement constitué par une fraise portée par un bras suspendu en partie haute du bouclier, permet de creuser et de fractionner la terre à l'avant du bouclier, cette terre étant éliminée vers l'arrière par un transporteur ; le bouclier hydraulique qui comprend un anneau de poussée sur lequel est attelé un système hydraulique de poussée, permet de faire progresser le bouclier après réalisation du terrassement avant approprié ; pour engendrer cette progression, l'anneau de poussée prend appui sur les tuyaux ou voussoirs déjà mis en place à l'arrière de la machine et le système hydraulique de poussée attelé à son autre extrémité sur le bouclier exerce sur ce dernier un effort d'avancement.We already know such machines which are essentially composed of a hydraulic shield and a slaughter device housed inside the shield. The slaughtering device, generally constituted by a cutter carried by an arm suspended in the upper part of the shield, makes it possible to dig and split the earth at the front of the shield, this earth being eliminated towards the rear by a conveyor; the hydraulic shield which includes a thrust ring on which a hydraulic thrust system is coupled, allows the shield to advance after completion of the appropriate front earthwork; to generate this progression, the thrust ring is supported on the pipes or segments already installed at the rear of the machine and the hydraulic thrust system hitched at its other end to the shield exerts an effort on the latter advancement.

De telles machines qui sont depuis longtemps bien connues des professionnels présentent plusieurs défauts auxquels on n'a pas su remédier jusqu'à présent.Such machines which have long been well known to professionals have several faults which have so far been unable to be remedied.

En premier lieu, les courbes sont très délicates à réaliser avec ce type de machine et nécessitent des terrassements hors profil. de grandes sections et donc un personnel relativement important ; de plus, les cour- bes sont réalisées à très grands rayons (les rayons de courbure atteints étant généralement supérieurs à environ 100 fois le diamètre de la galerie). Au surplus, dans certains terrains très meubles, il s'avère parfois impossible de réaliser des courbes avec les machines connues et les professionnels sont obligés de recourir à des terrassements entièrement manuels. En outre, même en ligne droite, ces machines sont mal adaptées au creusement de terrains meubles qui ont tendance à "bourrer" le dispositif d'abattage à fraise et à absorber des puissances très importantes.First of all, the curves are very delicate to realize with this type of machine and require earthworks out of profile. large sections and therefore relatively large staff; moreover, the curves are made with very large radii (the radii of curvature reached being generally greater than about 100 times the diameter of the gallery). In addition, in some very loose terrain, it sometimes turns out to be impossible to make curves with known machines and professionals are forced to resort to entirely manual earthworks. Furthermore, even in a straight line, these machines are ill-suited tees when digging loose soil which tends to "stuff" the cutter with strawberries and absorb very large powers.

La présente invention se propose de remédier aux défauts des machines connues sus-évoquées, en fournissant une machine perfectionnée, conçue pour fonctionner suivant le même principe général que les machines connues.The present invention proposes to remedy the faults of the known machines mentioned above, by providing an improved machine, designed to operate according to the same general principle as the known machines.

Un objectif essentiel de l'invention est en particulier d'autoriser la réalisation de courbes beaucoup plus prononcées et ce, sans avoir à effectuer des terrassements hors profils ; l'invention vise notamment à permettre de réaliser des courbes dont les rayons puissent être aisément ajustés jusqu'à une valeur minimum de l'ordre de 15 fois le diamètre de l'ouvrage.An essential objective of the invention is in particular to authorize the production of much more pronounced curves, without having to perform earthworks outside of the profiles; the invention aims in particular to allow curves to be produced, the radii of which can be easily adjusted to a minimum value of the order of 15 times the diameter of the structure.

Un autre objectif est de fournir une machine adaptée pour travailler en tout terrain et notamment en terrain meuble aussi bien en lignes droites qu'en lignes courbes.Another objective is to provide a machine adapted to work in any terrain and in particular in soft ground as well in straight lines as in curved lines.

Un objectif de l'invention est ainsi de fournir une machine universelle qui puisse, sans difficultés, creuser des galeries dans des terrains présentant des couches de natures différentes.An objective of the invention is thus to provide a universal machine which can, without difficulty, dig galleries in soils having layers of different natures.

A cet effet, la machine visée par l'invention est du type comprenant, d'une part, un bouclier hydraulique pourvu d'un.anneau de poussée et d'un système hydraulique de poussée, d'autre part, un dispositif d'abattage logé à l'intérieur du bouclier ; conformément à la présente invention, ladite machine est caractérisée en ce que le bouclier comprend deux parties mobiles l'une par rapport à l'autre :

  • - une partie avant, dite trousse coupante, supportant intérieurement le dispositif d'abattage,
  • - et une partie arrière, dite jupe d'assemblage, servant de guide à l'anneau de poussée,
  • - ladite trousse coupante et ladite jupe d'assemblage étant liées entre-elles par une fixation flottante adaptée pour les assujettir l'une à l'autre, d'une part, dans le sens longitudinal, d'autre part, en rotation autour de leur axe longitudinal, tout en autorisant un pivotement de faible amplitude de l'une par rapport à l'autre autour d'un axe orthogonal à leur axe longitudinal, de façon à permettre de les orienter l'une par rapport à l'autre dans une configuration angulaire telle que leurs axes longitudinaux forment un angle α ajustable.
To this end, the machine covered by the invention is of the type comprising, on the one hand, a hydraulic shield provided with a thrust ring and a hydraulic thrust system, on the other hand, a device for slaughter housed inside the shield; in accordance with the present invention, said machine is characterized in that the shield comprises two parts which are movable relative to one another:
  • - a front part, called a cutting kit, internally supporting the slaughter device,
  • - and a rear part, called a skirt assembly, serving as a guide for the thrust ring,
  • - said cutting kit and said assembly skirt being linked together by a floating attachment adapted to secure them to each other, on the one hand, in the longitudinal direction, on the other hand, in rotation around their longitudinal axis, while allowing a small amplitude pivoting of one relative to the other about an axis orthogonal to their longitudinal axis, so as to allow them to be oriented relative to each other in an angular configuration such that their longitudinal axes form an adjustable angle α.

(Il est à noter que les termes "avant" et "arrière" se réfèrent au sens de progression de la machine ; en outre, les termes "horizontal" et "vertical"qui sont utilisés plus loin, supposent la machine en position de travail, les axes longitudinaux de la trousse coupante et de la jupe d'assemblage étant horizontaux).(It should be noted that the terms "front" and "rear" refer to the direction of travel of the machine; in addition, the terms "horizontal" and "vertical" which are used later, assume the machine in the working position , the longitudinal axes of the cutting bag and the assembly skirt being horizontal).

Selon un mode de réalisation préféré, la fixation flottante entre la trousse coupante et la jupe d'assemblage est adaptée de façon à permettre à ladite trousse et à ladite jupe un pivotement relatif ajustable jusqu'à une valeur de 4° environ.According to a preferred embodiment, the floating attachment between the cutting kit and the assembly skirt is adapted so as to allow said kit and said skirt an adjustable relative pivoting up to a value of approximately 4 °.

La fixation flottante précitée peut en particulier comprendre une pluralité de pattes d'accouplement et de plots de traction, répartis autour du bouclier et assujettis les uns à l'avant dela jupe d'assemblage, les autres à l'arrière de la trousse coupante, chaque plot de traction pénétrant dans une lumière d'une patte d'accouplement avec un débattement adapté pour permettre le pivotement relatif précité entre ladite trousse coupante et ladite jupe d'assemblage.The aforementioned floating attachment may in particular comprise a plurality of coupling lugs and traction studs, distributed around the shield and secured one to the front of the assembly skirt, the other to the rear of the cutting kit, each traction pad penetrating into a lumen of a coupling tab with a clearance adapted to allow the aforementioned relative pivoting between said cutting kit and said assembly skirt.

autre De plus, selon une/caractéristique de l'invention, la trousse coupante comprend, solidarisée à sa partie arrière, une bague de centrage externe dans laquelle est emboitée une bague de centrage interne solidarisée à l'avant de la jupe d'assemblage, lesdites bagues étant dimensionnées de façon à être espacées d'un jeu fonctionnel adapté pour autoriser le pivotement relatif précité entre la trousse coupante et la jupe d'assemblage.other In addition, according to a feature of the invention, the cutting kit comprises, secured to its rear part, an external centering ring in which is fitted an internal centering ring secured to the front of the assembly skirt, said rings being dimensioned so as to be spaced from a functional clearance adapted to allow the aforementioned relative pivoting between the cutting kit and the assembly skirt .

Le dispositif hydraulique de poussée du bouclier est avantageusement constitué par plusieurs vérins hydrauliques à commandes indépendantes, répartis autour du bouclier , chaque vérin étant attelé, à l'avant, sur un support annulaire solidaire de la trousse coupante et, à l'arrière, sur l'anneau de poussée coulissant dans la jupe d'assemblage.The hydraulic pushing device of the shield advantageously consists of several hydraulic jacks with independent controls, distributed around the shield, each jack being coupled, at the front, on an annular support integral with the cutting kit and, at the rear, on the thrust ring sliding in the assembly skirt.

Ainsi, dans la machine conforme à l'invention, la partie avant du bouclier (trousse coupante) qui supporte le dispositif d'abattage peut être orientée selon une direction choisie de façon à former un angle ajustable par rapport à la partie arrière (jupe d'assemblage), laquelle permet la mise en place des éléments de revêtement. Le braquage de la trousse coupante est obtenu en commandant indépendamment les vérins de poussée au cours des manoeuvres de progression du bouclier : les vérins situés du côté extérieur de la courbe à réaliser sont amenés à subir un allonge- ment supérieur à ceux situés du côté intérieur, les rapports d'allongement définissant l'angle α de braquage. Le dispositif d'abattage peut ainsi travailler dans une direction angulaire décalée par rapport à la direction précédente, et ce, tout en autorisant, d'une part, un travail de type traditionnel au droit du profil de la trousse coupante, d'autre part, une mise en place classique des éléments de revêtement dans la jupe d'assemblage.Thus, in the machine according to the invention, the front part of the shield (cutting bag) which supports the slaughter device can be oriented in a chosen direction so as to form an adjustable angle relative to the rear part (skirt d 'assembly), which allows the placement of the covering elements. The deflection of the cutting kit is obtained by independently controlling the thrust cylinders during shield progression operations: the cylinders located on the outside of the curve to be produced are made to undergo an elongation greater than those located on the inside. , the elongation ratios defining the steering angle α. The slaughtering device can thus work in an angular direction offset from the previous direction, while allowing, on the one hand, a traditional type of work in line with the profile of the cutting kit, on the other hand , a conventional positioning of the covering elements in the assembly skirt.

Les essais ont démontré que l'obtention d'un angle de 4° entre la trousse coupante et la jupe d'assemblage, permet de réaliser des courbes de rayons s'abaissant jusqu'à environ 15 fois le diamètre du bouclier.Tests have shown that obtaining an angle of 4 ° between the cutting kit and the assembly skirt, makes it possible to produce radius curves lowering up to approximately 15 times the diameter of the shield.

Par ailleurs, selon d'autres caractéristiques de la machine perfectionnée conforme à l'invention, le dispositif d'abattage comprend :

  • . un bâti fixe assujetti à l'intérieur de la trousse coupante et formant autour de l'axe de ladite trousse une plateforme sensiblement verticale,
  • . une couronne à roulement portée par ladite plateforme de façon que son axe coincide sensiblement avec l'axe de la trousse coupante,
  • . un châssis tournant porté par la couronne à roulement précitée de façon à pouvoir pivoter sur 360°, sensiblement autour de l'axe de la trousse coupante,
  • . des moyens d'entrainement en rotation du châssis tournant,
  • . un bras d'abattage articulé sur le châssis tournant et doté à son extrémité d'un outil de travail,
  • . et un vérin hydraulique de manoeuvre dudit bras, attelé sur ledit bras et sur le châssis tournant de sorte que le point d'articulation du bras sur la châssis, le point d'attelage du vérin sur le châssis et le point d'attelage du vérin sur le bras ne soient jamais alignés.
Furthermore, according to other characteristics of the improved machine according to the invention, the slaughter device comprises:
  • . a fixed frame fixed inside the cutting kit and forming around the axis of said kit a substantially vertical platform,
  • . a rolling crown carried by said platform so that its axis substantially coincides with the axis of the cutting kit,
  • . a rotating chassis carried by the aforementioned rolling crown so as to be able to pivot 360 °, substantially around the axis of the cutting kit,
  • . means for driving the rotating chassis in rotation,
  • . a felling arm articulated on the rotating chassis and provided at its end with a working tool,
  • . and a hydraulic actuator for operating said arm, coupled to said arm and to the rotating chassis so that the point of articulation of the arm on the chassis, the coupling point of the cylinder on the chassis and the coupling point of the cylinder on the arm are never aligned.

Comme on comprendra mieux plus loin, cette disposition permet au br-as de balayer aisément la totalité de la section du front de taille (en avant de la trousse coupante) par le jeu combiné de la rotation sur 360° du bâti tournant et des manoeuvres du bras par rapport audit bâti tournant . De plus , l'outil peut être amené à travailler dans toutes les positions ; dans ces conditions, le bras est avantageusement équipé d'un godet apte à travailler en butte ou en rétro, qui permet de creuser sans difficulté aussi bien des terrains meubles que des terrains durs.As will be better understood later, this arrangement allows the br-as to easily sweep the entire section of the cutting face (in front of the cutting bag) by the combined game of the 360 ° rotation of the rotating frame and the maneuvers. of the arm relative to said rotating frame. In addition, the tool can be brought to work in all positions; under these conditions, the arm is advantageously equipped with a bucket capable of working in mound or retro, which allows digging without difficulty as well as soft ground than hard ground.

En outre, selon une autre caractéristique de l'invention qui facilite la pénétration du godet dans les terres à l'avant de la trousse coupante, le bras d'abattage est télescopique et est équipé d'un vérin hydraulique permettant sa rétraction ou son extension.In addition, according to another characteristic of the invention which facilitates the penetration of the bucket into the soil in front of the cutting kit, the felling arm is telescopic and is equipped with a hydraulic cylinder allowing its retraction or its extension .

La machine perfectionnée représentée à titre d'exemple aux figures 1, 2, 3, 4 et 5 est destinée à la réalisation de galeries souterraines, de diamètre pouvant varier entre 1,80 et 6 mètres. Cette machine comprend essentiellement, d'une part, un bouclier composé de deux pièces, une trousse coupante avant 1 et une jupe d'assemblage arrière 2, d'autre part, un dispositif d'abattage 3 porté par la trousse coupante 1.The improved machine shown by way of example in FIGS. 1, 2, 3, 4 and 5 is intended for the production of underground galleries, of diameter which can vary between 1.80 and 6 meters. This machine essentially comprises, on the one hand, a shield made up of two parts, a front cutting kit 1 and a rear assembly skirt 2, on the other hand, a slaughtering device 3 carried by the cutting kit 1.

La trousse coupante 1 se présente sous la forme d'un tube cylindrique en acier pourvu d'une casquette supérieure la à sa partie avant ; à sa partie arrière, elle est dotée d'une bague de centrage externe 4 qui est souaée sur ladite trousse de façon que son épaisseur vienne en saillie à l'extérieur de la trousse 1, comme le montre la figure 5.The cutting kit 1 is in the form of a cylindrical steel tube provided with a cap 1a at its front part; at his party rear, it is provided with an external centering ring 4 which is welded onto said kit so that its thickness protrudes outside the kit 1, as shown in FIG. 5.

De plus, plusieurs plots de traction tels que 5, par exemple au nombre de six, sont soudés intérieurement à l'arrière de la trousse coupante 1 et répartis sur le pourtour de celle-ci, au voisinage de sa jonction avec la bague 4.In addition, several traction pads such as 5, for example six in number, are welded internally to the rear of the cutting kit 1 and distributed around the periphery thereof, in the vicinity of its junction with the ring 4.

En outre, sur une portion intermédiaire de la trousse coupante 1 est soudée à l'intérieur de celle-ci un support annulaire 6 sur lequel sont articulés plusieurs vérins hydrauliques tels que 7 (par exemple au nombre de six), répartis sur le pourtour du bouclier. Le corps de chacun de ces vérins est articulé sur le support 6 par une chappe classique.In addition, on an intermediate portion of the cutting kit 1 is welded inside thereof an annular support 6 on which are articulated several hydraulic cylinders such as 7 (for example six in number), distributed around the periphery of the shield. The body of each of these jacks is articulated on the support 6 by a conventional clevis.

Par ailleurs, la jupe d'assemblage2 se présente sous la forme d'un tube cylindrique en acier, dont le diamètre légèrement plus grand que celui de la trousse 1 est de l'ordre de celui de la bague externe 4 soudée à l'arrière de ladite trousse.Furthermore, the assembly skirt 2 is in the form of a cylindrical steel tube, the diameter of which is slightly larger than that of the kit 1 is of the order of that of the outer ring 4 welded at the rear. of said kit.

A l'avant de la jupe 2, est soudée une bague de centrage interne 8 dont l'épaisseur vient en saillie à l'intérieur de ladite jupe comme le montre la figure 5. La bague 8 est emboitée dans la bague 4, avec un jeu fonctionnel entre celles-ci, adapté pour autoriser un pivotement relatif de la trousse coupante par rapport à la jupe d'assemblage autour d'un axe quelconque orthogonal à l'axe de ces éléments. Les bagues 4 et 8 qui se recouvrent sur une distance longitudinale variable fonction de la position relative de la jupe et de la trousse, réalisent un guidage et un centrage relatif de ces éléments, évitant tout risque de décalage transversal.At the front of the skirt 2, an internal centering ring 8 is welded, the thickness of which protrudes inside said skirt as shown in FIG. 5. The ring 8 is fitted into the ring 4, with a functional clearance between them, adapted to allow relative pivoting of the cutting bag with respect to the assembly skirt around any axis orthogonal to the axis of these elements. The rings 4 and 8 which overlap over a variable longitudinal distance as a function of the relative position of the skirt and the case, provide guiding and relative centering of these elements, avoiding any risk of transverse shift.

De plus, plusieurs pattes d'accouplement telles 9, en l'exemple au nombre de six, sont soudées intérieurement à l'avant de la bague de centrage 8, au niveau des plots de traction 5. Chaque patte d'accouplement 9 est dotée d'une lumière 9a, de dimension longitudinale très su- périeure à celle d'un plot de traction 5 et de dimension transversale légèrement supérieure à celle de ce dernier. Chacun des plots 5 pénètre dans une lumière 9a d'une patte, de sorte que l'ensemble de ces organes constitue une fixation flottante assu- jettisant l'une à l'autre avec un débattement déterminé la jupe 2 et la trousse 1, d'une part, dans le sens longitudinal, d'autre part, en rotation autour de leur axe longitudinal, tout en autorisant un pivotement de ces éléments de sorte que leurs axes longitudinaux forment un angle donné, cet angle pouvant aller jusqu'à une valeur maximum d'environ 4°.In addition, several coupling lugs such as 9, in the example of six in number, are welded internally at the front of the centering ring 8, at the level of the traction pads 5. Each coupling lug 9 is provided a light 9a, of longitudinal dimension very much greater than that of a traction pad 5 and of slight transverse dimension higher than the latter. Each of the studs 5 penetrates into a lumen 9a of a tab, so that all of these members constitute a floating attachment subjecting the skirt 2 and the kit 1, d to each other with a determined clearance. on the one hand, in the longitudinal direction, on the other hand, in rotation about their longitudinal axis, while allowing a pivoting of these elements so that their longitudinal axes form a given angle, this angle being able to go up to a value maximum of about 4 °.

Par ailleurs, la jupe 2 guide un anneau de poussée 10 qui est monté coulissant dans celle-ci. Sur cet anneau sont attelés, de façon classique en soi, les tiges mobiles des vérins hydrauliques 7. Ces vérins sont équipés d'un système de distribution hydraulique permettant de les alimenter et de les commander indépendamment de façon à pouvoir régler individuellement leur allongement et ajuster ainsi la position angulaire relative de la trousse 1 par rapport à la jupe 2.Furthermore, the skirt 2 guides a thrust ring 10 which is slidably mounted therein. On this ring are coupled, in a conventional manner in themselves, the movable rods of the hydraulic cylinders 7. These cylinders are equipped with a hydraulic distribution system allowing them to be supplied and to be controlled independently so as to be able to individually adjust their elongation and adjust thus the relative angular position of the kit 1 relative to the skirt 2.

Le dispositif d'abattage 3 porté par la trousse tranchante 1 comprend un bâti 11 possédant trois extensions en forme de tripode, par lesquelles il est fixé à l'intérieur de la trousse coupante 1, vers la portion arrière de celle-ci. Ce bâti forme autour de l'axe de la trousse une plateforme sensiblement verticale lla, ledit bâti et sa plateforme étant évidés dans la région centrale de la trousse en vue de délimiter une volume central creux.The slaughtering device 3 carried by the sharp kit 1 comprises a frame 11 having three tripod-shaped extensions, by which it is fixed inside the cutting kit 1, towards the rear portion thereof. This frame forms around the axis of the kit a substantially vertical platform 11a, said frame and its platform being hollowed out in the central region of the kit in order to delimit a hollow central volume.

Un châssis tournant 12 est monté à l'avant du bâti 11 sur la plateforme verticale lla par l'entremise d'une couronne à roulements de type connu, (symbolisée en 13 aux figures 1 et 2) ; cette couronne d'axe horizontal coincidant avec l'axe de la trousse peut être du type à galets croisés, sa cage externe étant assujettie sur la plateforme lla et sa cage interne sur le châssis 12. Cette dernière est dotée d'une denture 14 en prise avec un pignon 15 qui est articulé sur la plateforme lla et entraîné en rotation par un moteur hydraulique 16 porté à l'arrière par ladite plateforme lia.A rotating chassis 12 is mounted at the front of the frame 11 on the vertical platform 11a by means of a crown of bearings of known type, (symbolized at 13 in Figures 1 and 2); this crown of horizontal axis coinciding with the axis of the kit can be of the crossed roller type, its external cage being fixed on the platform lla and its internal cage on the chassis 12. The latter has teeth 14 in taken with a pinion 15 which is articulated on the platform 11a and rotated by a hydraulic motor 16 carried at the rear by said platform 11a.

Le châssis tournant 12 peut ainsi être entrainé en rotation sur 360° autour d'un axe horizontal concidant sensiblement avec l'axe de la trousse tranchante 1 .The rotating frame 12 can thus be rotated 360 ° around a horizontal axis substantially coinciding with the axis of the sharp case 1.

Sur ce châssis tournant est articulé un bras d'abattage 18, par un axe 17 parallèle au plan de la plateforme lla et situé au voisinage de celui-ci, cet axe d'articulation étant excentré par rapport au centre fictif de la plateforme. De plus, le bras d'abattage 18 comporte un prolongement arrière 18a qui vient se loger dans la partie creuse du bâti 11. Sur ce prolongement, est attelé par un axe 19 la tige mobile d'un vérin de manoeuvre 20. Ce vérin est incliné vers l'arrière comme le montre la figure 1 et son corps est attelé sur une extension avant 12a du châssis tournant, en un point d'attelage 21 situé à l'opposé du point d'articulation 17 du bras, par rapport à l'axe de la trousse tranchante.On this rotating chassis is articulated a felling arm 18, by an axis 17 parallel to the plane of the platform 11a and located in the vicinity thereof, this articulation axis being eccentric relative to the fictitious center of the platform. In addition, the felling arm 18 has a rear extension 18a which is housed in the hollow part of the frame 11. On this extension, the movable rod of an actuating cylinder 20 is coupled by an axis 19. This cylinder is tilted back as shown in Figure 1 and its body is coupled to a front extension 12a of the rotating frame, at a coupling point 21 located opposite the articulation point 17 of the arm, relative to the axis of the sharp case.

Le point d'articulation 17 du bras et les points d'attelages 19 et 21 du vérin de manoeuvre sont ainsi agencés en triangle et la disposition ci-dessus décrite de ces éléments permet à la fois de garantir une bonne efficacité du vérin de manoeuvre quelle que soit la position du bras 18 et de réduire considérablement l'encombrement à l'avant de la plateforme de façon à dégager l'aire de travail et à autoriser un balayage de toute la surface de cette aire par le bras (et ce, malgré la division du bouclier en deux pièces, qui conditionne une réduction notable de la dimension longitudinale de la trousse coupante dans laquelle est logé le dispositif d'abattage).The articulation point 17 of the arm and the coupling points 19 and 21 of the maneuvering cylinder are thus arranged in a triangle and the arrangement described above of these elements makes it possible both to guarantee good efficiency of the maneuvering cylinder which that is the position of the arm 18 and considerably reduce the space requirement at the front of the platform so as to clear the work area and allow the entire surface of this area to be swept by the arm (despite the division of the shield into two parts, which conditions a significant reduction in the longitudinal dimension of the cutting bag in which the slaughter device is housed).

Par ailleurs, le bras d'abattage 18 est avantageusement prévu télescopique et comprend deux membrures 18b, 18c montées coulissantes l'une par rapport à l'autre et un vérin hydraulique 22 situé à l'intérieur de ces dernières et attelé à celles-ci en vue de mouvoir la membrure 18b par rapport à la membrure 18c dans le sens d'une rétraction ou d'une extension longitudinale.Furthermore, the felling arm 18 is advantageously telescopic and comprises two members 18b, 18c mounted to slide relative to one another and a hydraulic cylinder 22 located inside the latter and coupled to them in order to move the member 18b relative to the member 18c in the direction of a retraction or a longitudinal extension.

La membrure 18b est équipée à son extrémité d'un godet 23 qui est associé à des moyens hydrauliques de manoeuvre classiques, comprenant un vérin hydraulique 24 et des bielles de transmission 25, en vue de permettre au godet d'être disposé aussi bien en position butte qu'en position rétro.The member 18b is equipped at its end with a bucket 23 which is associated with conventional hydraulic maneuvering means, comprising a hydraulic cylinder 24 and transmission rods 25, in order to allow the bucket to be disposed both in position butte that retro position.

Les différents vérins solidaires du châssis tournant 12 (vérins 20, 22 et 24) sont alimentés en huile sous pression par un joint tournant hydraulique de type classique 26.The various cylinders integral with the rotary chassis 12 (cylinders 20, 22 and 24) are supplied with pressurized oil by a hydraulic rotary joint of the conventional type 26.

Le dispositif d'abattage ci-dessus décrit est apte à creuser efficacement aussi bien les terrains meubles que les terrains plus durs ; par le jeu du balayage du bras et de la rotation à 360°, le godet peut être amené à travailler indifféremment en butte ou en rétro, la nature télescopique du bras autorisant une bonne pénétration du godet vers l'avant.The above-described felling device is capable of effectively digging both loose and harder soils; by the play of the sweeping of the arm and the 360 ° rotation, the bucket can be brought to work indifferently in hillock or in retro, the telescopic nature of the arm allowing a good penetration of the bucket forward.

Un tel dispositif d'abattage est adaptée à la structure en deux pièces distinctes du bouclier et est dépourvu des défauts des dispositifs classiques à fraise.Such a slaughter device is adapted to the structure in two separate parts of the shield and is free from the defects of conventional strawberry devices.

La terre détachée par le dispositif est éliminée vers l'arrière, de façon traditionnelle, par un convoyeur qui a été schématisé en 27 aux figures 1, 2 et 3 ; ce convoyeur passe à travers une ouverture prévue dans le pied inférieur du bâti 11.The earth detached by the device is removed backwards, in the traditional way, by a conveyor which has been shown diagrammatically at 27 in FIGS. 1, 2 and 3; this conveyor passes through an opening provided in the lower leg of the frame 11.

Les figures 6 à 10 illustrent le fonctionnement de la machine pour réaliser une galerie courbe.Figures 6 to 10 illustrate the operation of the machine to produce a curved gallery.

Au début du cycle de fonctionnement, la machine est supposée dans la configuration de la figure 6. L'axe X de la trousse coupante 1 forme un angle α avec l'axe Y de la jupe d'assemblage 2, cet angle étant fonction de la courbure de la galerie à réaliser. Les vérins 7 sont à l'état rétracté, ceux situés à l'extérieur de la courbe ayant des allongements plus importants adaptés aux distances variables qui séparent les points d'attelage des divers vérins sur le support avant 6 et sur l'anneau coulissant 10. Ce dernier se trouve dans sa position la plus en avant, en appui contre les derniers revêtements qui ont été mis en place dans la jupe (voussoirs V).At the start of the operating cycle, the machine is assumed in the configuration of FIG. 6. The axis X of the cutting kit 1 forms an angle α with the axis Y of the assembly skirt 2, this angle being a function of the curvature of the gallery to achieve. The jacks 7 are in the retracted state, those situated outside the curve having greater elongations adapted to the variable distances which separate the coupling points of the various jacks on the front support 6 and on the sliding ring 10 The latter is in its most forward position, pressing against the last coverings which have been put in place in the skirt (segments V).

La fixation flottante entre trousse 1 et jupe 2 se trouve dans la position schématisée à la figure 7. Des cales de différentes longueurs, telles que schématisées en traits discontinus en 27 , peuvent être mises en place pour bloquer la jupe et la trousse tranchante dans la configuration angulaire appropriée, définie par l'allongement différentiel des vérins 7. Ces cales amovibles peuvent en particulier être disposées manuellement contre les plots de traction 5 dans les lumières des pattes d'accouplement 9. L'ensemble des cales ainsi mises en place permet, au cours des mouvements de progression du bouclier, de conserver de façon précise la valeur de l'angle« entre les axes X et Y de la trousse et de la jupe.The floating attachment between kit 1 and skirt 2 is in the position shown diagrammatically in FIG. 7. Wedges of different lengths, as shown diagrammatically in broken lines at 27, can be put in place to block the skirt and the sharp case in the appropriate angular configuration, defined by the differential elongation of the jacks 7. These removable wedges can in particular be manually placed against the traction studs 5 in the slots of the coupling lugs 9. The set of wedges thus put in place makes it possible, during the movements of progression of the shield, to keep precisely the value of the angle "between the axes X and Y of the case and the skirt.

Lorsque le dispositif d'abattage (non schématisé à ces figures) a creusé une nouvelle longueur de boyau, les vérins 7 sont manoeuvrés indépendamment dans le sens de l'extension pour mouvoir le bouclier vers l'avant. (figure 8). Ce mouvement est obtenu grâce à l'appui de l'anneau de poussée 10 sur les voussoirs V qui maintiennent cet anneau immobile : sous la poussée des vérins 7, la trousse coupante 1 est donc amenée à glisser vers l'avant dans la nouvelle longueur creusée et la jupe d'assemblage 2 suit/le mouvement de progression lui étant transmis par les plots de traction 5 en prise avec les pattes 9 ainsi que par les vérins 7 qui lient la trousse coupante et la jupe d'assemblage.When the slaughter device (not shown diagrammatically in these figures) has dug a new length of hose, the jacks 7 are operated independently in the direction of the extension to move the shield forward. (figure 8). This movement is obtained by pressing the pushing ring 10 on the segments V which keep this ring stationary: under the push of the jacks 7, the cutting bag 1 is therefore caused to slide forward in the new length hollowed out and the assembly skirt 2 follows / the progression movement being transmitted to it by the traction studs 5 engaged with the lugs 9 as well as by the jacks 7 which link the cutting kit and the assembly skirt.

Lorsque la trousse coupante 1 est parvenue à l'extrémité de la longueur creusée, les vérins 7 sont rétractés en les manoeuvrant indépendamment de façon à préserver leur allongement différentiel (figure 9) : l'anneau coulissant est alors ramené vers l'avant de la jupe d'assemblage 2.When the cutting kit 1 has reached the end of the dug length, the jacks 7 are retracted by maneuvering them independently so as to preserve their differential elongation (FIG. 9): the sliding ring is then brought back towards the front of the assembly skirt 2.

Il suffit alors de monter, de façon traditionnelle, de nouveaux voussoirs (V') dans la jupe d'assemblage 2 et un nouveau cycle peut commencer (Figure 10).It then suffices to mount, in the traditional way, new segments (V ′) in the assembly skirt 2 and a new cycle can begin (FIG. 10).

Une telle machine dans laquelle la trousse coupante 1 et la jupe d'assemblage 2 sont aptes à former un angle atteignant jusqu'à 4° permet de réaliser sans difficulté des galeries ayant des courbures atteignant jusqu'à 15 fois leur diamètre ; trois personnes suffisent pour la desservir et l'avancement moyen peut être de l'ordre de 5 mètres par poste de 8 heures.Such a machine in which the cutting kit 1 and the assembly skirt 2 are capable of forming an angle reaching up to 4 ° makes it possible without difficulty to produce galleries having curvatures reaching up to 15 times their diameter; three people are enough to serve it and the average progress can be of the order of 5 meters per shift of 8 hours.
