Abstract

The present invention provides a device for digging trenches, including at least one digging wheel with a wheel framework which is connected to a vehicle by means of a mobile carriage for lowering or raising the wheel, further including: first means for causing said digging wheel to pivot about a first pivoting axis orthogonal to the plane defined by the direction of movement of the vehicle and the axis of rotation of said wheel, and second means capable of causing said wheel to pivot about a second pivoting axis orthogonal to the plane defined by said first pivoting axis and an axis parallel to the rotational axis of the wheel.

Description

La présente invention concerne un dispositif pour creuser des tranchées.The present invention relates to a device for digging trenches.

On connait déjè des dispositifs pour creuser des tranchées, comportant au moins une roue trancheuse pouvant tourner autour d'un axe et munie d'un châssis de roue, lequel est relié à un véhicule par l'intermédiaire d'un chariot mobile permettant d'abaisser ou de relever la roue trancheuse.There are already known devices for digging trenches, comprising at least one cutting wheel which can rotate about an axis and provided with a wheel chassis, which is connected to a vehicle by means of a mobile carriage allowing lower or raise the slicer wheel.

Or, si de tels dispositifs sont tout à fait appropriés pour creuser des tranchées en ligne droite et sur terrain plat, il n'en est pas de même dans le cas où il s'avère nécessaire de creuser une tranchée dont l'axe est dévié par rapport à la ligne droite, par exemple dans une courbe, ou dans le cas où, compte tenu des inégalités de terrain, le véhicule présente un certain dévers. Ainsi, dans le premier cas, la courbure de la tranchée risque d'être irrégulière, tandis que, dans le second cas, le fond de la tranchée risque d'être également inégal. Dans les deux cas, la pose de câbles, ou analogues, à laquelle les tranchées ainsi creusées sont généralement destinées, présentera des difficultés.However, if such devices are entirely suitable for digging trenches in a straight line and on flat ground, it is not the same in the case where it turns out to be necessary to dig a trench whose axis is deviated relative to the straight line, for example in a curve, or in the case where, taking into account uneven terrain, the vehicle has a certain slope. Thus, in the first case, the curvature of the trench may be irregular, while, in the second case, the bottom of the trench may also be uneven. In both cases, laying cables, or the like, for which the trenches thus dug are generally intended, will present difficulties.

La présente invention a pour but d'éviter ces inconvénients, et concerne un dispositif pour creuser des tranchées permettant, quel que soit le terrain et quelle que soit la trajectoire du véhicule, de creuser une tranchée régulière et parfaitement adaptée à la pose de câbles, ou analogues.The object of the present invention is to avoid these drawbacks, and relates to a device for digging trenches allowing, whatever the terrain and whatever the trajectory of the vehicle, to dig a regular trench which is perfectly suited for laying cables, or the like.

A cet effet, le dispositif pour creuser des tranchées, du type indiqué ci-dessus, est remarquable, selon l'invention, en ce qu'il comprend :
- des premiers moyens susceptibles de faire pivoter, de façon limitée, ladite roue trancheuse autour d'un premier axe de pivotement orthogonal au plan défini par la direction de déplacement du véhicule et l'axe de rotation de la roue, et
- des deuxièmes moyens susceptibles de faire pivoter, de façon limitée, ladite roue trancheuse autour d'un deuxième axe de pivotement orthogonal au plan défini par ledit premier axe de pivotement et un axe parallèle à l'axe de rotation de la roue.To this end, the device for digging trenches, of the type indicated above, is remarkable, according to the invention, in that it comprises:
first means capable of pivoting, in a limited manner, said cutting wheel about a first pivot axis orthogonal to the plane defined by the direction of movement of the vehicle and the axis of rotation of the wheel, and
- Second means capable of pivoting, in a limited manner, said cutting wheel around a second pivot axis orthogonal to the plane defined by said first pivot axis and an axis parallel to the axis of rotation of the wheel.

Ainsi, il est possible d'orienter précisément la roue trancheuse dans l'espace, quelles que soient les inégalités de terrain, et cela même dans une courbe.Thus, it is possible to precisely orient the slicer wheel in space, whatever the unevenness of the ground, and this even in a curve.

En particulier, ladite roue trancheuse peut pivoter d'un angle maximum de pivoement compris, à chaque fois, entre environ 10° et environ 15°, de part et d'autre d'une position intermédiaire de la roue.In particular, said slicer wheel can pivot by a maximum pivot angle comprised, each time, between approximately 10 ° and approximately 15 °, on either side of an intermediate position of the wheel.

Selon une autre caractéristique de l'invention, ledit châssis de roue est relié audit chariot par une pièce intermédiaire articulée, d'une part, audit châssis de roue autour dudit premier axe de pivotement et fixée, d'autre part, audit chariot en pouvant pivoter, de façon limitée par rapport audit chariot autour dudit deuxième axe de pivotement.According to another characteristic of the invention, said wheel chassis is connected to said carriage by an intermediate piece articulated, on the one hand, to said wheel chassis around said first pivot axis and fixed, on the other hand, to said carriage by being able pivot, in a limited manner relative to said carriage around said second pivot axis.

Advantageusement, lesdists premiers moyens de pivotement comprennent un vérin, ou analogue, relié, d'une part, audit châssis de roue et, d'autre part, à ladite pièce intermédiaire, tandis que lesdits deuxièmes moyens de pivotement peuvent comprendre un vérin, ou analogue, relié, d'une part, à ladite pièce interédiaire et, d'autre part, audit chariot.Advantageously, the first pivot means comprise a jack, or the like, connected, on the one hand, to said wheel chassis and, on the other hand, to said intermediate part, while said second pivot means can comprise a jack, or similar, connected, on the one hand, to said intermediate piece and, on the other hand, to said carriage.

Selon une autre caractéristique de l'invention, le dispositif comprend des moyens pour déplacer ledit chariot transversalement à la direction de déplacement dudit véhicule.According to another characteristic of the invention, the device comprises means for moving said carriage transversely to the direction of movement of said vehicle.

Avantageusement, lesdits moyens de déplacement transversal du chariot comprennent un vérin, ou analogue, relié, d'une part, audit chariot et, d'autre part, audit véhicule.Advantageously, said means for transversely moving the carriage comprise a jack, or the like, connected, on the one hand, to said carriage and, on the other hand, to said vehicle.

Selon encore une autre caractéristique de l'invention, ledit châssis de roue présente une forme générale de L dont une première branche est reliée audit chariot par l'intermédiaire dudit premier axe de pivotement et dont la seconde branche porte la roue, lesdites première et seconde branches étant articulées l'une à l'autre par l'intermédiaire d'un troisième axe de pivotement parallèle à l'axe de rotation de la roue, des troisièmes moyens de pivotement, constitués d'au moins un vérin, ou analogue, pouvant relier les extrémités éloignées desdites première et seconde branches.According to yet another characteristic of the invention, said wheel chassis has a general shape of L, a first branch of which is connected to said carriage via said first pivot axis and the second branch of which carries the wheel, said first and second branches being articulated to each other by means of a third pivot axis parallel to the axis of rotation of the wheel, third pivot means, consisting of at least one jack, or the like, capable of connecting the far ends of said first and second branches.

Enfin, pour éviter l'accumulation de terre qui risquerait d'encrasser les différents axes, la roue est munie, au voisinage de toute sa périphérie, de perçages angulairement espacés.Finally, to avoid the accumulation of soil which could clog the different axes, the wheel is provided, in the vicinity of its entire periphery, with angularly spaced holes.

Le dispositif 1 pour creuser une tranchée 2 comporte une roue trancheuse 3 pouvant tourner autour d'un axe 4 et qui est munie, à sa périphérie, d'une pluralité d'outils de coupe 5 angulairement espacés.The device 1 for digging a trench 2 comprises a cutting wheel 3 which can rotate around an axis 4 and which is provided, at its periphery, with a plurality of cutting tools 5 angularly spaced.

La roue trancheuse 3 est montée sous un châssis de roue 6 et peut être monté, par exemple, sur une plaque 7 de fixation de la roue 3 au châssis 6.The slicer wheel 3 is mounted under a wheel chassis 6 and can be mounted, for example, on a plate 7 for fixing the wheel 3 to the chassis 6.

La châssis de roue 6 est relié à un véhicule 8 par l'intermédiaire d'un chariot mobile 9 permettant d'abaisser ou de relever la roue trancheuse 3, la position relevée de la roue étant représentée en traits mixtes sur la figure 1.The wheel chassis 6 is connected to a vehicle 8 by means of a mobile carriage 9 making it possible to lower or raise the slicer wheel 3, the raised position of the wheel being shown in phantom in FIG. 1.

Selon l'invention, le dispositif 1 comprend des premiers moyens, constitués, dans cet exemple de réalisation,par un vérin 10, susceptibles de faire pivoter, de façon limitée, la roue trancheuse 3 autour d'un premier axe de pivotement 11 orthogonal au plan défini par la direction de déplacement F du véhicule 8 et l'axe de rotation 4 de la roue trancheuse 3, et des deuxièmes moyens, constitués, dans cet exemple de réalisation, par un vérin 12, susceptibles de faire pivoter, de façon limitée, la roue trancheuse 3 autour d'un deuxième axe de pivotement 13 orthogonal au plan défini par le premier axe de pivotement 11 et un axe parallèle à l'axe de rotation 4 de la roue 3.According to the invention, the device 1 comprises first means, constituted, in this embodiment, by a jack 10, capable of pivoting, in a limited manner, the cutting wheel 3 around a first pivot axis 11 orthogonal to the plane defined by the direction of movement F of the vehicle 8 and the axis of rotation 4 of the cutting wheel 3, and of the second means, constituted, in this exemplary embodiment, by a jack 12, capable of pivoting, in a limited manner , the slicer wheel 3 around a second pivot axis 13 orthogonal to the plane defined by the first pivot axis 11 and an axis parallel to the axis of rotation 4 of the wheel 3.

Comme on peut mieux le voir sur la figure 3, sur laquelle le vérin 10 est agencé de façon opposée par rapport au cas des figures 1 et 2, le châssis de roue 6 est relié au chariot 9 par une pièce intermédiaire 14 articulée, d'une part, au châssis de roue 6 autour du premier axe de pivotement 11 et fixée, d'autre part, au chariot 9 en pouvant pivoter, de façon limitée, par rapport au chariot 9 autour du deuxième axe de pivotement 13. L fixation de la pièce intermédiaire 14 au chariot 9 sera expliquée ci-après, plus en détail, en référence aux figures 4 et 5.As can best be seen in FIG. 3, in which the jack 10 is arranged opposite to the case in FIGS. 1 and 2, the wheel chassis 6 is connected to the carriage 9 by an articulated intermediate piece 14, of on the one hand, to the wheel chassis 6 around the first pivot axis 11 and fixed, on the other hand, to the carriage 9 while being able to pivot, in a limited manner, relative to the carriage 9 around the second pivot axis 13. The fixing of the intermediate part 14 of the carriage 9 will be explained below, in more detail, with reference to FIGS. 4 and 5.

Comme on peut mieux le voir sur la figure 4, le vérin 10 est relié, d'une part, au châssis de roue 6 par une chape 15 et, d'autre part, à la pièce intermédiaire 14 par une chape 16.As can best be seen in Figure 4, the jack 10 is connected, on the one hand, to the wheel chassis 6 by a yoke 15 and, on the other hand, to the intermediate part 14 by a yoke 16.

En outre, le vérin 12 est relié, d'une part à la pièce intermédiaire 14 par une chape 17 (figure 4) et, d'autre part, au chariot 9 par une chape 18 fixée au chariot par une patte de fixation 19 (figures 5 et 6).In addition, the jack 12 is connected, on the one hand to the intermediate piece 14 by a yoke 17 (FIG. 4) and, on the other hand, to the carriage 9 by a yoke 18 fixed to the carriage by a fixing lug 19 ( Figures 5 and 6).

De plus, le chariot 9 est guidé en translation (montée et descente) sur des rails 20 de section transversale en C et à l'aide de galets 21.In addition, the carriage 9 is guided in translation (up and down) on rails 20 of cross section at C and using rollers 21.

La face avant 22 du chariot 9 est munie de cinq pions 23 (figure 5), et la plaque 24 correspondante de la pièce intermédiaire 14 est munie d'un trou central circulaire 40 traversé en position montée par le pion central 23 jouant alors le rôle du deuxième axe de pivotement 13, et de quatre lumière arquées 25 (traversées par le quatre autres pions 23) permettant le pivotement limité de la pièce intermédiaire 14 par rapport au chariot 9 autour de l'axe 13. Le trou central 40 et les lumières arquées 25 sont représentés en traits interrompus dur la figure 5. L'ensemble du chariot 9 et de la pièce intermédiaire 14 est maintenu par des écrous 26 coopérant, chacun, avec les pions 23.The front face 22 of the carriage 9 is provided with five pins 23 (FIG. 5), and the corresponding plate 24 of the intermediate piece 14 is provided with a circular central hole 40 traversed in the mounted position by the central pin 23 then playing the role of the second pivot axis 13, and of four arcuate slots 25 (crossed by the other four pins 23) allowing the limited pivoting of the intermediate piece 14 relative to the carriage 9 around the axis 13. The central hole 40 and the lights 25 are shown in dashed lines in FIG. 5. The assembly of the carriage 9 and of the intermediate piece 14 is held by nuts 26 each cooperating with the pins 23.

La pièce intermédiaire 14, et donc la roue 3, peuvent pivoter autour de l'axe 13 par rapport au chariot 9 d'un angle maximum A égal, par exemple, à 14°, de part et d'autre d'une position intermédiaire (figure 5.). De mêe, la roue 3 peut pivoter autour de l'axe 11 d'un angle maximum B égal, par exemple, à 12°, de part et d'autre d'une position intermédiaire (figure 4).The intermediate part 14, and therefore the wheel 3, can pivot around the axis 13 relative to the carriage 9 by a maximum angle A equal, for example, to 14 °, on either side of an intermediate position (figure 5.). Similarly, the wheel 3 can pivot around the axis 11 by a maximum angle B equal, for example, to 12 °, on either side of an intermediate position (Figure 4).

En outre, le dispositif 1 comprend un vérin 27 (figure 2) pour déplacer le chariot 9, avec sa potence de support 28, transversalement à la direction de déplacement F du véhicule 8. Le vérin 27 est relié, d'une part, au véhicule 8 par une chape 29 et, d'autre part, à la potence 28 par une chape 30. L'ensemble du chariot 9 et de la potence 28 peut ainsi coulisser transversalement le long de rails de guidage 31 de section transversale en C.In addition, the device 1 comprises a jack 27 (FIG. 2) for moving the carriage 9, with its support bracket 28, transversely to the direction of movement F of the vehicle 8. The jack 27 is connected, on the one hand, to the vehicle 8 by a yoke 29 and, on the other part, to the bracket 28 by a yoke 30. The assembly of the carriage 9 and the bracket 28 can thus slide transversely along guide rails 31 of cross section in C.

Dans cet exemple de réalisation, le châssis de roue 6 présente une forme générale de L dont une première branche 32 est reliée au chariot 9 par l'intermédiaire du premie axe de pivotement 11 et de la pièce intermédiaire 14, et dont la seconde branche 33 porte la roue 3. Les première 32 et seconde 33 branches sont articulées l'une à l'autre par l'intermédiaire d'un troisième axe de pivotement 34 parallèle à l'axe de rotation de la roue 3. Deux vérins 35, disposés de part et d'autre de la roue 3, relient les extrémités élloignées desdites première 32 et seconde 33 branches en étant montés sur des chapes 36 et 37, respectivement, en pouvant ainsi relever la roue 3 en la faisant pivoter autour de l'axe 34.In this exemplary embodiment, the wheel chassis 6 has a general shape of L, a first branch 32 of which is connected to the carriage 9 via the first pivot axis 11 and the intermediate part 14, and the second branch of which 33 carries the wheel 3. The first 32 and second 33 branches are articulated to each other by means of a third pivot axis 34 parallel to the axis of rotation of the wheel 3. Two jacks 35, arranged on either side of the wheel 3, connect the distant ends of said first 32 and second 33 branches by being mounted on yokes 36 and 37, respectively, thus being able to raise the wheel 3 by rotating it around the axis 34.

Enfin, pour éviter l'accumulation de terre qui risquerait d'encrasser, notamment, les différents axes, la roue 3 est munie, au voisinage de toute sa périphérie, de perçages 38 angulairement espacés.Finally, to avoid the accumulation of soil which could clog, in particular, the different axes, the wheel 3 is provided, in the vicinity of its entire periphery, with holes 38 angularly spaced.

Le dispositif de l'invention permet ainsi d'orienter dans l'espace la roue trancheuae de façon à toujours obtenir une tranchée régulière parfaitement adaptée à la pose de câbles, ou analogues. The device of the invention thus makes it possible to orient the trench wheel in space so as to always obtain a regular trench perfectly suited for laying cables, or the like.
