Abstract
Description
La présente invention concerne un engin pour travaux du sol, comportant un véhicule pourvu d'un bras à l'extrémité duquel est- monté un outil de travail. Elle est particulièrement, quoique non exclusivement, adaptée aux engins pourvus d'un outil tranchant, tel que soc ou roue trancheuse, permettant l'ouverture d'une tranchée latérale parallèle à l'avance du véhicule, par exemple pour y déposer des câbles ou des conduites.The present invention relates to a machine for working the soil, comprising a vehicle provided with an arm at the end of which is mounted a working tool. It is particularly, although not exclusively, suitable for machines provided with a cutting tool, such as a ploughshare or a cutting wheel, allowing the opening of a lateral trench parallel to the advance of the vehicle, for example for depositing cables or pipes.
D'une part, on connaît déjà des engins, tels que des pelleteuses, munis d'un outil de travail disposé à l'extrémité d'un bras solidaire d'un véhicule, générale- ment automoteur. Dans ce genre d'engins, les efforts subis par ledit outil ont une résultante au moins sensiblement dans l'axe du bras, de sorte que celui-ci peut, par un dimensionnement adéquat, facilement résister auxdits efforts.On the one hand, machines are already known, such as excavators, provided with a working tool placed at the end of an arm secured to a vehicle, generally self-propelled. In this type of machine, the forces undergone by said tool have a result at least substantially in the axis of the arm, so that the latter can, by adequate dimensioning, easily withstand said forces.
D'autre part, on connaît également des engins pourvus d'outils tranchants destinés à ouvrir des tranchées.On the other hand, there are also known devices provided with cutting tools intended to open trenches.
Dans ce cas, l'outil tranchant, qui subit des efforts importants, est porté directement par le véhicule et se trouve au voisinage de l'axe longitudinal de celui-ci.In this case, the cutting tool, which undergoes significant forces, is carried directly by the vehicle and is located in the vicinity of the longitudinal axis thereof.
Avec de tels engins, il est donc impossible d'ouvrir une tranchée latérale au trajet suivi-par le véhicule, par exemple une voie ferrée.With such devices, it is therefore impossible to open a lateral trench in the path followed by the vehicle, for example a railway.
La présente invention a pour objet de remédier à cet inconvénient et de permettre notamment de creuser des tranchées éloignées latéralement du véhicule. Pour cela, elle perfectionne les engins à bras du premier type cité pour leur permettre de supporter des efforts importants transversaux (et non plus axiaux) audit bras. The object of the present invention is to remedy this drawback and to allow in particular to dig trenches distant laterally from the vehicle. For this, it improves the arm machines of the first type mentioned to allow them to withstand significant forces transverse (and no longer axial) to said arm.
A cette fin, selon l'invention, l'engin pour travaux du sol, comportant un véhicule pourvu d'un bras à l'extrémité duquel est monté un outil de travail, est remarquable en ce qu'il comporte des moyens de support roulant entraînés, disposés à l'extrémité dudit bras opposée au véhicule et supportant au moins partiellement ledit outil.To this end, according to the invention, the machine for working the soil, comprising a vehicle provided with an arm at the end of which is mounted a working tool, is remarkable in that it comprises rolling support means driven, arranged at the end of said arm opposite the vehicle and at least partially supporting said tool.
Ainsi, grace à la présence de ces moyens de support roulant entraînés avançant en fonction de la propre avance'du véhicule, le bras ne travaille pas en porte a-faux; de sorte que ledit bras peut supporter aisément, sans surdimensionnement important, les efforts transversaux résultant du travail de l'outil.Thus, thanks to the presence of these driven rolling support means advancing as a function of the vehicle's own advance, the arm does not work in overhang; so that said arm can easily withstand, without significant oversizing, the transverse forces resulting from the work of the tool.
Ces moyens de support roulant entrainés peuvent comporter au moins une roue ou une chenille. De préférence, ils comportent un moteur hydraulique commandé, à travers des canalisations passant le long dudit bras, par une centrale hydraulique portée par le véhicule.These driven rolling support means may comprise at least one wheel or a track. Preferably, they comprise a hydraulic motor controlled, through pipes passing along said arm, by a hydraulic unit carried by the vehicle.
Avantageusement, de façon connue, le bras est solidaire d'une tourelle montée sur le véhicule et susceptible de tourner autour d'un axe vertical. De plus, le bras peut, pour relever ou baisser l'outil, être monté pivotant autour d'un axe horizontal.Advantageously, in known manner, the arm is integral with a turret mounted on the vehicle and capable of turning around a vertical axis. In addition, the arm can, to raise or lower the tool, be pivotally mounted about a horizontal axis.
Le bras peut être constitué de plusieurs éléments aptes à coulisser les uns par rapport aux autres, afin de permettre le réglage de sa longueur.The arm can be made up of several elements capable of sliding relative to each other, in order to allow the adjustment of its length.
De préférence, les moyens de support roulant sont orientables à l'extrémité du bras. Ainsi, notamment dans le cas où pendant le travail, le véhicule se déplace, l'outil peut être commandé pour suivre une trajectoire parallèle & celle du véhicule.Preferably, the rolling support means are orientable at the end of the arm. Thus, in particular in the case where during work, the vehicle moves, the tool can be controlled to follow a trajectory parallel to that of the vehicle.
Dans le cas particulier où l'engin selon l'invention est destiné à poser des câbles dans une tranchée,lesdits câbles étant préalablement posés sur le sol à l'emplacement de la tranchée, il comporte de préférence une roue trancheuse rotative et lesdits moyens de support roulant comportent des organes de guidage soulevant lesdits câbles au passage de l'outil pour les déposer dans la tranchée au fur et à mesure de l'avance dudit outil.In the particular case where the machine according to the invention is intended for laying cables in a trench, said cables being previously laid on the ground at the location of the trench, it preferably comprises a rotary cutting wheel and said means of rolling support comprise guide members lifting said cables when the tool passes to deposit them in the trench as and when said tool advances.
Dans un mode de réalisation préféré de l'invention, le véhicule comporte deux jeux d'organes de roulement différents et mis en service alternativement et lui permettant de se déplacer au choix soit sur le sol,soit sur des rails.In a preferred embodiment of the invention, the vehicle comprises two sets of different rolling members and put into service alternately and allowing it to move either on the ground or on rails.
L'invention sera bien comprise à la lumière des figures annexées.The invention will be clearly understood in the light of the appended figures.
La figure 1 représente un schéma en perspective d'un mode de réalisation de l'engin selon l'invention.FIG. 1 represents a perspective diagram of an embodiment of the machine according to the invention.
La figure 2 est un schéma en perspective de l'extrémité du bras muni de l'outil et des moyens de support.Figure 2 is a perspective diagram of the end of the arm provided with the tool and the support means.
La figure 3 est une vue de coté de l'engin avec son bras en position relevée.Figure 3 is a side view of the machine with its arm in the raised position.
Les figures 4 et 5 sont des vues schématiques en perspective, respectivement de l'avant et de l'arrière des organes montés à l'èxtrémité du bras.Figures 4 and 5 are schematic perspective views, respectively of the front and rear of the members mounted at the end of the arm.
La figure 6 est un schéma illustrant le creusement d'une tranchée et la pose d'un câble, au moyen de l'engin selon l'invention.FIG. 6 is a diagram illustrating the digging of a trench and the laying of a cable, by means of the machine according to the invention.
Les figures représentent un exemple d'application particulier de l'engin selon l'invention, à savoir la pose et l'enfouissement de câbles, ou de conduites souples.The figures show an example of a particular application of the machine according to the invention, namely the laying and burial of cables, or flexible pipes.
L'engin ou le dispositif selon l'invention est apte à se déplacer à la surface du sol par l'intermédiaire du véhicule 1 et est muni d'un outil 2. L'outil 2 est constitué, dans l'exemple des figures, par un organe tranchant 3 rotatif, associé à un talon 4 permettant de maintenir sur une certaine distance les parois de la tranchée ouverte par l'organe tranchant 3. Le véhicule 1 comporte une tourelle 5, mobile en rotation autour d'un axe vertical et solidaire d'un bras 6 à l'extrémité duquel est fixé un bati 7. Ledit bâti 7 est solidaire de l'outil 2 ainsi que des moyens de support mobile 8 codstitués d'un ensemble de deux roues 9 et 10 reliées par une chenille 11.Ces derniers permettent au bâti 7 muni de l'outil 2 de reposer sur le sol et de le déplacer de façon que le bras 6 ne subisse que peu ou pas d'effort transversal.The machine or device according to the invention is capable of moving on the surface of the ground by means of the vehicle 1 and is provided with a tool 2. The tool 2 consists, in the example of the figures, by a rotating cutting member 3, associated with a heel 4 making it possible to maintain the walls of the trench open by the cutting member 3 over a certain distance. The vehicle 1 comprises a turret 5, movable in rotation about a vertical axis and secured to an arm 6 at the end of which a frame is fixed 7. Said frame 7 is secured to the tool 2 as well as movable support means 8 made up of a set of two wheels 9 and 10 connected by a caterpillar 11. These allow the frame 7 provided with the tool 2 to rest on the ground and to move it so that the arm 6 undergoes little or no transverse force.
Le bras 6 est articulé sur la tourelle de manière à pouvoir pivoter selon un axe horizontal, grâce à des moyens de levage tels que les vérins 14 et 15 disposés de chaque côtX du bras 6.The arm 6 is articulated on the turret so as to be able to pivot along a horizontal axis, by means of lifting means such as the jacks 14 and 15 arranged on each side of the arm 6.
La figure 2 montre le bâti 7 comportant une partie 17 mobile en translation verticale par rapport au montant 18. L'outil 2 est monté sur un cadre 19 articulé en rotation par rapport à ladite partie 17 grâce au vérin 16.FIG. 2 shows the frame 7 comprising a part 17 movable in vertical translation relative to the upright 18. The tool 2 is mounted on a frame 19 articulated in rotation relative to said part 17 thanks to the jack 16.
Le véhicule 1 comporte deux moteurs actionnant chacun une centrale hydraulique 19 et 20; un premier moteur 12 permet le déplacement (avancement et direction) sur le sol du véhicule 1 ainsi que la manoeuvre du bras 6 et un second moteur 13 permet l'alimentation en énergie hydraulique des moyens de support 8 et de l'outil 2 disposés à l'extrémité du bras 6. La transmission de l'énergie hydraulique est réalisée grâce à des conduites reliant la centrale hydraulique 19,20 et les differents moteurs d'entrainement des organes.The vehicle 1 comprises two motors each actuating a hydraulic unit 19 and 20; a first motor 12 allows the movement (advancement and direction) on the ground of the vehicle 1 as well as the operation of the arm 6 and a second motor 13 allows the supply of hydraulic energy to the support means 8 and the tool 2 disposed at the end of the arm 6. The transmission of hydraulic energy is carried out by means of pipes connecting the hydraulic unit 19,20 and the various drive motors of the members.
L'organe tranchant rotatif 3 est entralné par un moteur hydraulique 21 ainsi que la roue motrice 10 par un moteur hydraulique 22. On comprend l'avantage de cette disposition qui autorise une grande simplicité et autonomie du bras 6 et des organes disposés sur le bâti 7, par rapport au véhicule 1.The rotary cutting member 3 is driven by a hydraulic motor 21 as well as the drive wheel 10 by a hydraulic motor 22. We understand the advantage of this arrangement which allows great simplicity and autonomy of the arm 6 and of the organs arranged on the frame 7, relative to vehicle 1.
Le véhicule 1 comporte d'une part un premier ensemble de roues 23,23',24,24' lui permettant de se déplacer sur des voies routières, et d'autre part un second ensemble de roues 25,25',26,26' adaptées au roulement sur des rails de voie ferrée. Le second ensemble de roues est escamotable grâce à des vérins tels que 27 et 28, afin de permettre le déplacement du véhicule 1, soit sur des rails, soit sur une voie routière. L'exemple des figures se rapporte à l'application du dispositif de l'invention à la pose et l'enfouissement de câbles le long d'une voie ferrée. Les figures 1,4,5,6 montrent le dispositif selon l'invention en service.The vehicle 1 comprises on the one hand a first set of wheels 23,23 ', 24,24' allowing it to move on roadways, and on the other hand a second set of wheels 25,25 ', 26,26 '' suitable for running on rail tracks. The second set of wheels is retractable by means of jacks such as 27 and 28, in order to allow the movement of the vehicle 1, either on rails or on a road. The example of the figures relates to the application of the device of the invention to laying and burying cables along a railroad track. Figures 1,4,5,6 show the device according to the invention in service.
Le véhicule 1 se déplace sur la voie ferrée 27 vers la gauche selon la figure 1, en reposant sur son second ensemble de roues 25,25',26,26', tandis que le premier ensemble de roues est utilisé pour la locomotion par frottement de ces roues sur les rails. The vehicle 1 moves on the railway track 27 to the left according to FIG. 1, resting on its second set of wheels 25,25 ', 26,26', while the first set of wheels is used for locomotion by friction of these wheels on the rails.
Au fur et à mesure de l'avancement, le câble 30,préala blement disposé à terre, est soulevé par des mâts 31,32 et33 munis de guides, au-dessus des moyens de support 8, du bâti 7 et de l'organe rotatif tranchant 3, pour être disposé dans la tranchée creusée par ledit organe tranchant 3, ladite tranchée pouvant être refermée des la pose du câble par un outil solidaire des moyens 8 (non représenté).As it progresses, the cable 30, previously disposed on the ground, is lifted by masts 31, 32 and 33 provided with guides, above the support means 8, the frame 7 and the member rotary cutting edge 3, to be disposed in the trench dug by said cutting member 3, said trench being able to be closed as soon as the cable is laid by a tool secured to the means 8 (not shown).
On comprend que l'effort découlant de la résistance du terrain creusé est repris en grande partie, sinon en totalité, par les moyens de support mobile 9 qui entrainent le bâti 7 et l'outil 2. Le bras 6 ne subit ainsi pratiquement pas d'effort transversal; cette disposition est grandement avantageuse du fait de la position en porte-à-faux dudit bras.It will be understood that the force arising from the resistance of the excavated ground is largely, if not entirely, taken up by the mobile support means 9 which drive the frame 7 and the tool 2. The arm 6 is thus practically not subjected to 'transversal effort; this arrangement is greatly advantageous because of the cantilever position of said arm.
La distance séparant la voie ferrée 29 de la tranchée d'enfouissement du câble 30 peut être ajustée par réglage de la longueur du bras 6. A cette fin, ledit bras est constitué de plusieurs sections aptes à coulisser les unes dans les autres afin de réduire ou d'augmenter la longueur du bras.The distance separating the railroad track 29 from the cable burial trench 30 can be adjusted by adjusting the length of the arm 6. To this end, said arm consists of several sections capable of sliding into one another in order to reduce or increase the length of the arm.
La tranchée peut ainsi être réalisée à proximité immédiate de la voie (compte tenu de l'encombrement latéral minimum de l'ensemble) ou bien à plusieurs mètres de cette même voie.The trench can thus be made in the immediate vicinity of the track (taking into account the minimum lateral size of the assembly) or even several meters from this same track.
Le dispositif selon l'invention présente en outre une grande mobilité puisqu'il permet le franchissement d'ouvrages d'art ou d'obstacles (tels que poteaux).En effet, les différentes articulations du bras par rapport à la tourelle, de cette dernière par rapport au véhicule, et de l'outil 2 par rapport au bâti 7, autorisent cette souplesse d'utilisation.The device according to the invention also has great mobility since it allows the crossing of engineering structures or obstacles (such as posts). Indeed, the different articulations of the arm relative to the turret, of this last relative to the vehicle, and the tool 2 relative to the frame 7, allow this flexibility of use.
A l'approche d'un obstacle ou d'un ouvrage d'art, le processus est le suivant. En premier lieu, l'entraIne- ment du véhicule 1 et de la roue motrice 10 (et donc de la chenille 11) est stoppé puis celui de l'organe tranchant rotatif 3; on fait ensuite pivoter le cadre 19'grâce au vérin 16 afin de dégager ledit organe tranchant 3 et le talon 4 de la tranchée; l'ensemble outil 2 et partie 17 est alors translaté verticalement le long du montant 18 du bâti 7, achevant ainsi de sortir ledit ensemble de la tranchée (voir la figure 2). Le bâti 7 et ses organes solidaires sont ensuite élevés par rotation du bras 6 par rapport à la tourelle 5 (voir la figure 3); on peut éventuellement diminuer la longueur dudit bras pour faciliter la manoeuvre de passage de l'obstacle. La succession des opérations se déroule dans l'ordre inverse après le franchissement.When approaching an obstacle or a structure, the process is as follows. Firstly, the drive of the vehicle 1 and of the drive wheel 10 (and therefore of the track 11) is stopped then that of the rotary cutting member 3; the frame 19 ′ is then pivoted thanks to the jack 16 in order to release said cutting member 3 and the heel 4 from the trench; the tool 2 and part 17 assembly is then translated vertically along the upright 18 of the frame 7, thus completing the removal of said assembly from the trench (see FIG. 2). The frame 7 and its integral members are then raised by rotation of the arm 6 relative to the turret 5 (see Figure 3); the length of said arm may possibly be reduced to facilitate the maneuver for passing the obstacle. The succession of operations takes place in reverse order after crossing.
Cette souplesse d'utilisation est avantageuse car le long de voies ferrées, on sait que le nombre et la variété d'obstacles sont élevés.This flexibility of use is advantageous because along railways, it is known that the number and variety of obstacles are high.
Le dispositif selon l'invention permet en outre de réaliser une tranchée à une distance relativement éloignée de la voie, là où les possibilités d'accès sont souvent réduites et rendent impossible l'emploi de dispositifs connus.The device according to the invention also allows a trench to be made at a distance relatively distant from the track, where the possibilities of access are often reduced and make the use of known devices impossible.
Le dispositif selon l'invention peut également être utilisé sur une voie routière, ou éventuellement sur un terrain quelconque, par escamotage du second ensemble de roues 25,25',26,26'.The device according to the invention can also be used on a road, or possibly on any terrain, by retracting the second set of wheels 25,25 ', 26,26'.
La tourelle 5 pivotante permet, par rotation de 1800, de placer le bras et l'outil 2 de l'autre coté du véhicule 1, qui peut ainsi effectuer le meme travail sur le coté opposé au précédent de la voie, et en se déplaçant en sens inverse.The pivoting turret 5 allows, by rotation of 1800, to place the arm and the tool 2 on the other side of the vehicle 1, which can thus perform the same work on the side opposite to the previous one of the track, and by moving reverse.
Lors du creusement de la tranchée, le cadre 19 supportant l'outil 2 comporte un carénage 35, en forme de U ouvert vers ledit outil, afin d'éviter les projections de terre et de pierres.When digging the trench, the frame 19 supporting the tool 2 includes a fairing 35, in the shape of a U open towards said tool, in order to avoid projections of earth and stones.
Avantageusement, pour conserver la mobilité du véhicule due aux organes de direction de ce dernier, les moyens de locomotion 8 sont orientables suivant un axe vertical, par rapport au bâti 7 (et donc au bras 6).Advantageously, to preserve the mobility of the vehicle due to the steering organs of the latter, the locomotion means 8 can be oriented along a vertical axis, relative to the frame 7 (and therefore to the arm 6).
r
On a décrit un exemple particulier d'application du dispositif selon l'invention, mais on conçoit que tout type d'outil peut être disposé à l'extrémité du bras 6. r
A particular example of application of the device according to the invention has been described, but it will be appreciated that any type of tool can be placed at the end of the arm 6.
