Description

Dispositif de compensation électrique et électronique pour outil multifonction de nivellement et de compactage.Electrical and electronic compensation device for multifunction leveling and compaction tool.

Le secteur technique de l'invention est le domaine des travaux publics et la fabrication de matériel et machine pour ces travaux.The technical field of the invention is the field of public works and the manufacture of equipment and machinery for this work.

L'invention est relative aux machines pour le nivèlement et le compactage dans les deux sens pour la construction de remblais routiers et autres. Elle concerne les machines comportant à l'avant un outil multifonction composé d'une lame déplaçant les matériaux dans les deux sens en assurant leur nivellement et de patins vibrants pour les compacter.The invention relates to machines for leveling and compaction in both directions for the construction of road embankments and others. It concerns machines with a front multifunction tool consisting of a blade moving materials in both directions by ensuring their leveling and vibrating pads to compact them.

Une des applications principales de l'invention est la réalisation des remblais routiers, des aéroports, des digues en terre, des voies ferrées, des fondations de sols stabilisés.One of the main applications of the invention is the realization of road embankments, airports, earth embankments, railways, stabilized soil foundations.

Pour cela, dans la construction de terre-plein, de terrains de sports, et tous autres travaux de chaussée, travaux publics on procède à l'épandage des matériaux par des couches successives et pour les étaler on utilise une machine appeler «bouteur ou bulldozer» qui est un tracteur à chenille ou une chargeuse à roues caoutchoutées avec une lame niveleuse disposée à l'avant du bras, ou un godet permettant de dresser et de régler couche par couche les matériaux pour avoir une planimétrie parfaite.For this, in the construction of the median, sports fields, and all other road works, public works are spreading the materials by successive layers and for spreading they use a machine called "bulldozer or bulldozer "Which is a crawler tractor or a wheeled wheel loader with a grader blade placed at the front of the arm, or a bucket for setting and adjusting layer by layer the materials to have a perfect planimetry.

Pour procéder à l'opération de finition, on utilise une niveleuse. En raison de sa conception la niveleuse est longue et braque mal. Il arrive fréquemment que cette machine ne puisse pas être utilisée à cause de son encombrement et de son poids.To carry out the finishing operation, a grader is used. Because of its design the grader is long and stalks badly. It often happens that this machine can not be used because of its size and weight.

Quand il est nécessaire d'aplanir les matériaux avec précision, on utilise sur les niveleuses des moyens de guidage complémentaires tels que laser, TPS ou GPS pour étaler les couches de matériaux qui se trouvent à l'état mou. Ces couches sont soumises à une action compression par le poids de la niveleuse, tandis que le passage des roues provoque des distorsions dans le nivèlement. C'est pourquoi, il faut ensuite procéder à des opérations de compression et de damage.When it is necessary to flatten the materials accurately, it is used on the grader complementary guide means such as laser, TPS or GPS to spread the layers of materials that are in the soft state. These layers are subjected to compression action by the weight of the grader, while the passage of the wheels causes distortions in the leveling. Therefore, it is necessary to proceed to compression and grooming operations.

Cette opération est réalisée par des moyens spécifiques tels que des plaques vibrantes ou rouleaux vibrants qui assurent un compactage des couches étalées et compressées. L'opération n'est considérée achevée que lorsqu'est atteinte une valeur prescrite de la densité de la couche.This operation is carried out by specific means such as vibrating plates or vibrating rollers which compact the spread and compressed layers. The operation is only considered complete when a prescribed value of the density of the layer is reached.

Le procédé classique ci-dessus exposé nécessite d'avoir recours à diverses machines qui doivent passer plusieurs fois pour assurer un nivèlement supprimant les distorsions créer par le passage des roues de la niveleuse. L'exécution complète demande un temps important.The conventional method described above requires the use of various machines that must pass several times to ensure a leveling removing distortions created by the passage of the wheels of the grader. Full execution takes a long time.

Un objet de l'invention est de réaliser des remblais suivant les opérations décrites ci-dessus mais au moyen d'une seule machine équipée d'un outil multifonction pouvant assurer successivement ou simultanément les fonctions de nivèlement et de compactage suivant les besoins des travaux, la dite machine étant équipée de moyens de compensation électrique et électronique.An object of the invention is to provide embankments following the operations described above but by means of a single machine equipped with a multifunction tool that can successively or simultaneously the functions of leveling and compacting according to the needs of the work, said machine being equipped with electrical and electronic compensation means.

Cette machine comprend plusieurs châssis 22, 6 et 37 qui, solidaires et indépendants, sont actionnés par des moyens hydrauliques indépendants les uns des autres, et sont montés sur des pivots à rotules. L'ensemble est guidé par un opérateur qui est dans la cabine et muni d'une poignée multifonction 12 et d'un afficheur 19 de contrôle qui télécommande l'ouverture ou la fermeture de la distribution hydraulique mise sous pression par la pompe hydraulique de la machine appelée chargeuse.This machine comprises several frames 22, 6 and 37 which, solid and independent, are actuated by independent hydraulic means from each other, and are mounted on pivot pins. The assembly is guided by an operator who is in the cab and provided with a multifunction handle 12 and a control display 19 which remote control the opening or closing of the hydraulic distribution pressurized by the hydraulic pump of the machine called loader.

L'opérateur effectue le terrassement selon les données fournies par l'afficheur pour suivre le plan de terrassement et de compactage selon un plan parallèle au plan de référence laser. L'opérateur effectue la conduite en manuelle ou en automatique avec le calculateur qui régule les flux hydrauliques pour exercer des pressions avec les patins sur les matériaux, et monter ou descendre l'outil avec le bras de la machine.The operator performs the earthwork according to the data provided by the display to follow the plan of earthwork and compaction in a plane parallel to the laser reference plane. The operator carries out the manual or automatic operation with the computer which regulates the hydraulic flows to exert pressure with the pads on the materials, and to raise or lower the tool with the arm of the machine.

Dans la forme d'exécution représentée, le bras 2 de la chargeuse 1, sont actionnés par les moyens hydrauliques 3 et 4 et reçoivent par deux crochets renversés 5 un second châssis 6, contenant l'outil multifonction et un moyen hydraulique de rotation 7 au dessus d'une rotule 8. Le châssis 6 supporte un calculateur 9 relié à un bloc hydraulique 10, muni d'une valve 11 de régulation de la pression.In the embodiment shown, the arm 2 of the loader 1, are actuated by the hydraulic means 3 and 4 and receive by two reversed hooks 5 a second frame 6, containing the multifunction tool and a hydraulic means of rotation 7 to The frame 6 supports a computer 9 connected to a hydraulic block 10, provided with a valve 11 for regulating the pressure.

L'opérateur pilote l'outil avec une poignée multifonction 12 qui télécommande les moyens hydrauliques 4 pour faire monter ou descendre l'outil multifonction, selon la flèche 13. La lame 22 constituant le premier châssis porte un support 14 pour un détecteur 15 de faisceau laser 16 émis par un émetteur 17 à poste fixe. L'outil est piloté par l'opérateur avec la poignée 12 qui est équipée d'un interrupteur à bascule 18 à trois positions indiquées sur l'afficheur 19 à savoir :

  • position centrale A,
  • position B pour l'ouverture de la lame, montrée dans la figure 3,
  • et position C, pour la fermeture de la lame.
The operator controls the tool with a multifunctional handle 12 which remote controls the hydraulic means 4 to raise or lower the multifunction tool, according to the arrow 13. The blade 22 constituting the first frame carries a support 14 for a beam detector 15 laser 16 emitted by a stationary transmitter 17. The tool is driven by the operator with the handle 12 which is equipped with a toggle switch 18 with three positions indicated on the display 19, namely:
  • central position A,
  • position B for the opening of the blade, shown in the figure 3 ,
  • and position C, for closing the blade.

Ces positions, montrées sur l'afficheur de la figure 4, sont matérialisées par des moyens lumineux sur cet afficheur. Elles correspondent à des positions des moyens hydrauliques 20 solidaires de la bielle 21 et solidaires du second châssis 6 par la rotule centrale 8 et la bielle 21 articulée sur la lame 22 par un pivot 23. La lame est maintenue par des moyens hydrauliques 24 articulés sur la lame par des pivots à rotules 25 et sur le second châssis 6 par une articulation 26. Un deuxième moyen hydraulique 27 monté sur rotules 28 et 29, entre lame et châssis 6, assure l'orientation de la lame.These positions, shown on the display of the figure 4 , are materialized by luminous means on this display. They correspond to positions of the hydraulic means 20 integral with the connecting rod 21 and secured to the second frame 6 by the central ball 8 and the rod 21 hinged to the blade 22 by a pivot 23. The blade is held by hydraulic means 24 articulated on the blade by pivot pins 25 and the second frame 6 by a hinge 26. A second hydraulic means 27 mounted on ball joints 28 and 29 between the blade and frame 6 ensures the orientation of the blade.

L'opérateur fait fonctionner tous les moyens hydrauliques 7, 24, 20 et 27 avec les pressions hydrauliques qui arrivent par les canalisations 30 mises sous pression par la pompe hydraulique 31 de la machine 1.The operator operates all the hydraulic means 7, 24, 20 and 27 with the hydraulic pressures that come through the pipes 30 put under pressure by the hydraulic pump 31 of the machine 1.

A la figure 2 l'outil multifonction est en position de compactage avec les patins 32. Ceux-ci sont liés à la lame 22 qui les portent en partie basse par un châssis 37 articulé en 33 sur la lame et en 36 sur l'extrémité d'un moyen hydraulique 34, articulé par son autre extrémité en 35 sur le haut de la lameTo the figure 2 the multifunction tool is in compacting position with the pads 32. These are linked to the blade 22 which carry them in the lower part by a frame 37 hinged at 33 on the blade and at 36 on the end of a means hydraulic 34, articulated by its other end 35 on the top of the blade

Les patins vibrants 32 sont liés au châssis 37 par des moyens élastique 38 qui les supportent et, eux-mêmes, supportent les vibrateurs 39 et un capteur 40 de vibrations, disposé sur la semelle d'un patin et relié par un circuit 41 au calculateur 9.The vibrating pads 32 are connected to the frame 37 by elastic means 38 which support them and, themselves, support the vibrators 39 and a vibration sensor 40, disposed on the sole of a pad and connected by a circuit 41 to the computer 9.

Avec la pognée 12 l'opérateur actionne l'interrupteur 42 des moyens hydrauliques 34 qui sont munis d'un capteur 43 de course relié par un circuit 44 au calculateur 9, lui-même relié par un circuit 45 à l'afficheur 19 portant des voyants 46 indiquant la position de l'ouverture des patins 32, représentée par la flèche 47.With the handle 12 the operator actuates the switch 42 of the hydraulic means 34 which are provided with a stroke sensor 43 connected by a circuit 44 to the computer 9, itself connected by a circuit 45 to the display 19 carrying LEDs 46 indicating the position of the opening of the pads 32, represented by the arrow 47.

Cette ouverture s'effectue graduellement par gradients de 5 mm, 25 mm, 35mm, 50mm, en fonction de l'épaisseur 55 des matériaux nivelés par la lame 22 selon le plan de nivellement défini par le rayon laser 16 émis par le laser 17.This opening is done gradually by gradients of 5 mm, 25 mm, 35mm, 50mm, depending on the thickness 55 of the materials leveled by the blade 22 according to the leveling plane defined by the laser beam 16 emitted by the laser 17.

L'observation des témoins lumineux de la cellule de captage laser 15, permet de vérifier que le niveau de travail de la lame 22 est parallèle au plan de nivellement.The observation of the LEDs of the laser sensing cell 15 makes it possible to verify that the working level of the blade 22 is parallel to the leveling plane.

Dans cette configuration, le nivellement peut se combiner avec le compactage. A cette fin l'opérateur met en fonctionnement les vibrateurs 39 en actionnant l'interrupteur 48 de la poignée 12 reliée par un circuit câblé 49 à l'afficheur 19 comportant un voyant 50 d'indication du fonctionnement des vibrateurs. Il choisit la vitesse de fonctionnement des vibrateurs puis actionne par le bouton 51 de la poignée le fonctionnement automatique. Selon la variation de la hauteur 13 et la position de la valve de régulation 11, reliée par un circuit 52 au calculateur 9, celui-ci régule l'ouverture des patins 32 en marche avant, comme montré par la flèche 47 à la figure 2. Le taux de compactage est déterminé par le capteur de vibrations 40 relié par le circuit 41 à l'afficheur 9, lui-même relié aux boutons avec voyants 54 de l'afficheur 19.In this configuration, leveling can be combined with compaction. To this end, the operator puts the vibrators 39 into operation by operating the switch 48 of the handle 12 connected by a wired circuit 49 to the display 19 comprising an indicator 50 for indicating the operation of the vibrators. He chooses the speed of operation of the vibrators then actuates by the button 51 of the handle the automatic operation. According to the variation of the height 13 and the position of the regulating valve 11, connected by a circuit 52 to the computer 9, the latter regulates the opening of the pads 32 in the forward direction, as shown by the arrow 47 at the figure 2 . The compaction rate is determined by the vibration sensor 40 connected by the circuit 41 to the display 9, itself connected to the buttons with indicators 54 of the display 19.

Bien que les réglages varient selon l'épaisseur 55 des matériaux nivelés, à titre d'exemple on peut indiquer que pour un premier passage le taux de compactage est de 10% avec une ouverture des patins de 50 millimètres, représentée en 47 figure 2, alors que pour un deuxième passage le taux de compactage est de 50 % et l'ouverture de 35 millimètres. Pour un troisième passage, le taux de compactage est de 75%, l'ouverture de 25 millimètres, puis de 100% avec une ouverture de 5 millimètres. Si le taux de compactage dépasse 100% le calculateur 9 arrête les vibrateurs 39.Although the settings vary according to the thickness 55 of the leveled materials, for example it can be indicated that for a first pass the compaction rate is 10% with an opening of the pads of 50 millimeters, represented in 47 figure 2 , while for a second pass the compaction rate is 50% and the opening 35 mm. For a third pass, the compaction rate is 75%, the opening 25 mm, then 100% with an opening of 5 mm. If the compaction rate exceeds 100% the computer 9 stops the vibrators 39.

Le calculateur et les moyens de l'invention assurent un contrôle précis de la hauteur du nivelage et un compactage uniforme.The calculator and the means of the invention provide precise control of the leveling height and uniform compaction.

A la figure 3 l'outil est en position de compactage avec la lame 22 en position relevée.To the figure 3 the tool is in the compaction position with the blade 22 in the raised position.

Les patins 32 sont en position horizontale pour effectuer les compactages en avant ou en marche arrière, comme montré par les flèches 53 et 57.The pads 32 are in a horizontal position to perform the compactions forward or backward, as shown by the arrows 53 and 57.

Ils sont reliés au châssis 37 par des amortisseurs élastiques 38. Le châssis est monté sur les pivots 33 et est soutenu par les moyens hydrauliques 34 montés sur des pivots 35.They are connected to frame 37 by resilient dampers 38. The frame is mounted on pivots 33 and is supported by hydraulic means 34 mounted on pivots 35.

L'opérateur déclenche le compactage en actionnant l'interrupteur 18 de la poignée 12 afin que les voyants de l'afficheur 19 passent de la position A à la position B. Le calculateur 9 actionne les moyens hydrauliques 20 de relevage de la lame 22 et ceux 34 de placage des patins sur le sol, et reçoit les données des capteurs de vibrations 40 et des capteurs de course 60.The operator triggers the compaction by operating the switch 18 of the handle 12 so that the indicator lights of the display 19 change from position A to position B. The computer 9 actuates the hydraulic means 20 for raising the blade 22 and those 34 plating of the pads on the ground, and receives the data of vibration sensors 40 and stroke sensors 60.

L'opérateur actionne l'interrupteur 50 pour choisir la vitesse des vibrateurs 39, à savoir petite ou grande, puis actionne l'interrupteur 48 pour démarrer les vibrateurs 39, puis actionne l'interrupteur 51 pour mettre le dispositif en fonctionnement automatique. Cela permet au calculateur 9 de positionner les patins 32 à l'horizontal et la lame en position ouverte, comme montré par les flèches 56, pour la dégager de la surface de compactage 61. Par la suite, le calculateur 9 analyse les remontés des vibrations par le capteur 40, et les données récoltées sont transmises aux témoins lumineux 54 de l'afficheur 19 indiquant les pourcentages de compactage 10%, 50%, 75%, 100%. Le dernier témoin lumineux indique d'arrêter le vibrateur 39.The operator actuates the switch 50 to choose the speed of the vibrators 39, namely small or large, then actuates the switch 48 to start the vibrators 39, then actuates the switch 51 to put the device into automatic operation. This allows the computer 9 to position the pads 32 horizontally and the blade in the open position, as shown by the arrows 56, to disengage it from the compaction surface 61. Thereafter, the computer 9 analyzes the vibrations by the sensor 40, and the harvested data are transmitted to the indicator lights 54 of the display 19 indicating the compaction percentages 10%, 50%, 75%, 100%. The last light indicates to stop the vibrator 39.

A la figure 4, la lame 22 de l'outil multifonction est abaissée pour faire du terrassement et du nivèlement avec les patins 32 relevés.To the figure 4 , the blade 22 of the multifunction tool is lowered to earth and leveling with the pads 32 raised.

L'opérateur, pour effectuer le terrassement le nivèlement, pilote l'outil à partir de la poignée 12. Il amène l'interrupteur 18 en position C, ce qui allume le témoin lumineux C sur l'afficheur 19. Le calculateur 9 est ainsi programmé pour intervenir sur les moyens hydrauliques 20 et 34 et réguler leur fonctionnement, avec l'aide des capteurs 43 et 60 qui sont préenregistrés à cette position. Ainsi, l'opérateur effectue le terrassement et le nivèlement des matériaux 49 avec la lame 22, en position fermée montrée par la flèche 56, en marche avant et les patins 32 relevés au dessus du profil du nivèlement 49.The operator, to carry out the earthwork leveling, controls the tool from the handle 12. It brings the switch 18 to position C, which lights the indicator light C on the display 19. The computer 9 is thus programmed to intervene on the hydraulic means 20 and 34 and regulate their operation, with the help of the sensors 43 and 60 which are pre-recorded at this position. Thus, the operator performs the earthwork and the leveling of the materials 49 with the blade 22, in the closed position shown by the arrow 56, in the forward direction and the pads 32 raised above the leveling profile 49.

A la figure 5, la lame 22 en position fermée, est pivotée vers l'avant, comme montrée par la flèche 56 par les moyens hydrauliques 24 montés sur pivots à rotules 25 et 26. La lame 22 est pivotée par le moyen hydraulique 20, monté sur les pivots 58 et 59. La bielle 21 est articulée sur la lame 22 par son pivot 23 et par le pivot 8 elle est articulée sur le second châssis 6. Ainsi elle pivote selon la flèche 62 sous l'action des moyens hydrauliques 20, quand ceux-ci sont commandés par la poignée 12.To the figure 5 , the blade 22 in the closed position, is pivoted forwards, as shown by the arrow 56 by the hydraulic means 24 mounted on pivot pins 25 and 26. The blade 22 is pivoted by the hydraulic means 20, mounted on the pivots 58 and 59. The connecting rod 21 is articulated on the blade 22 by its pivot 23 and the pivot 8 is articulated on the second frame 6. Thus it pivots along the arrow 62 under the action of the hydraulic means 20, when these These are controlled by the handle 12.

A la figure 6 la lame 22 est en position ouverte vers l'arrière grâce à la rétraction de la tige 64 du moyen hydraulique 20 et au pivotement sur son pivot 8 de la bielle 21, selon la flèche 63. Le mouvement amenant la lame dans cette position est commandé à partir de la poignée multifonction 12 avec l'aide du calculateur 9 et le contrôle de l'afficheur 19.To the figure 6 the blade 22 is in the rearward open position thanks to the retraction of the rod 64 of the hydraulic means 20 and pivoting on its pivot 8 of the connecting rod 21, according to the arrow 63. The movement bringing the blade into this position is controlled from the multifunction handle 12 with the help of the computer 9 and the control of the display 19.

Il est évident que l'outil multifonction qui vient d'être décrit en référence aux figures, ne se limite pas aux réalisations décrites. Ainsi, les moyens hydrauliques de commande des mouvements, qui peuvent être des vérins, peuvent être remplacés par des moyens équivalents pneumatiques ou électriques remplissant les mêmes fonctions. De même les capteurs, décrits comme étant des capteurs linéaires intégrés, peuvent être remplacés par des capteurs à fil, à faisceau laser, à ultrason, T.P.S ou G.P.S, sans que l'on sorte du cadre de l'invention qui concerne l'amélioration du contrôle des moyens électriques et électroniques d'un outil multifonction de nivèlement et de compactage.It is obvious that the multifunction tool which has just been described with reference to the figures, is not limited to the embodiments described. Thus, the hydraulic movement control means, which may be cylinders, may be replaced by equivalent pneumatic or electrical means performing the same functions. Similarly, the sensors, described as integrated linear sensors, can be replaced by sensors wire, laser beam, ultrasound, TPS or GPS, without departing from the scope of the invention which relates to the improvement the control of electrical and electronic means of a multifunctional tool for leveling and compaction.
