Description

La présente invention est relative à un engin polyvalent d'un type nouveau , destiné à être utilisé notamment pour les travaux publics dans l'industrie du bâtiment , ou sur des chantiers de manutention ou de terrassements.The present invention relates to a multipurpose machine of a new type, intended to be used in particular for public works in the building industry, or on handling or earthworks.

Un engin de type connu est la pelleteuse orientable . Il comprend un châssis mobile sur des roues ,et portant un pivot vertical , autour duquel peut-tourner une cabine qui surmonte l'ensemble , cette cabine de commande portant par ailleurs l'embase d'un bras articulé , dont l'extrémité libre se termine par un godet excavateur . Le plancher tournant de la cabine pivotante comporte notamment une centrale hydraulique actionnée par un moteur thermique , ainsi qu'un poste de commande d'où l'opérateur , assis dans la cabine , peut commander , d'une part les vérins actionnant le bras articulé et le godet excavateur , d'autre part , la rotation de la cabine . Cet engin de type connu est utilisé comme pelleteuse , comme excavatrice , ou pour creuser des tranchées de plus ou moins grandes longueurs.A known type of device is the adjustable backhoe. It includes a frame movable on wheels, and carrying a vertical pivot, around which can rotate a cabin which overcomes the assembly, this control cabin also carrying the base of an articulated arm, the free end of which is ends with an excavator bucket. The revolving floor of the pivoting cabin notably includes a hydraulic unit actuated by a heat engine, as well as a control station from which the operator, seated in the cabin, can control, on the one hand, the jacks actuating the articulated arm and the excavator bucket, on the other hand, the rotation of the cabin. This known type of device is used as a backhoe, as an excavator, or to dig trenches of varying lengths.

Un autre engin de type différent , est connu sous le nom de chargeur . Son châssis , lui aussi mobile sur roues , porte l'articulation de base d'un bras relevable , dont l'extrémité libre est équipée d'un godet chargeur . Le châssis est surmonté par une cabine où l'opérateur , depuis son poste de commande , peut commander les mouvements de 1' engin , notamment au moyen des vérins hydrauliques actionnant le bras et le godet . Les engins de ce type sont utilisés pour prélever une charge au sol , et l'élever de quelques mètres avant de la déposer , ou vice versa.Another machine of a different type is known as a loader. Its chassis, also mobile on wheels, carries the basic articulation of a lifting arm, the free end of which is fitted with a loader bucket. The chassis is surmounted by a cabin where the operator, from his control station, can control the movements of the machine, in particular by means of hydraulic jacks actuating the arm and the bucket. Vehicles of this type are used to take a load from the ground, and raise it a few meters before depositing it, or vice versa.

Les pelleteuses et les chargeurs du type qui vient d'être décrit constituent des engins distincts , si bien qu'un utilisateur dont le chantier correspond à la fois à des opérations de pelletage et à des opérations de chargement doit se procurer séparément deux engins coûteux. Il en résulte une contrainte financière considérable , si bien que , sur de nombreux chantiers , les entrepreneurs ne possédant qu'un seul engin , sont amenés à le faire travailler dans de mauvaises conditions , lors d'opérations pour lesquelles il n'était pas prévu .Excavators and loaders of the type just described constitute separate devices, so that a user whose site corresponds to both shoveling operations and loading operations must obtain two expensive devices separately. This results in a considerable financial constraint, so that, on many sites, contractors having only one machine, are brought to make it work in bad conditions, during operations for which it was not planned. .

La présente invention a pour but d'éviter ces inconvénients , en réalisant un engin unique , mais polyvalent , convenant bien pour des utilisations multiples sur un chantier .The object of the present invention is to avoid these drawbacks, by making a single, but versatile machine, well suited for multiple uses on a site.

Un engin de travaux publics selon l'invention comprenant un châssis mobile surmonté d'une cabine pivotant de 360° autour d'un axe vertical , dans laquelle se trouve un poste de commande , muni d'un pupitre de distribution pour actionner divers vérins hydrauliques de l'engin qui comporte par ailleurs une centrale hydraulique à moteur thermique , est caractérisé en ce qu'il comporte , à la fois , en combinaison :

  • - un bras articulé de pelletage , dont l'extrémité libre comporte un godet de pelletage , alors que l'embase de son extrémité opposée est solidaire de la cabine tournante ;
  • - sur le châssis , un axe horizontal sur lequel est articulée l'embase d'un bras chargeur relevable , dont l'extrémité libre est équipée d'un porte-outils susceptible de recevoir de façon Interchangeable , un godet élévateur , ou une fourche de manutention.
A public works machine according to the invention comprising a mobile chassis surmounted by a cabin pivoting 360 ° about a vertical axis, in which there is a control station, provided with a distribution console for actuating various hydraulic cylinders of the machine which moreover comprises a hydraulic power station with an internal combustion engine, is characterized in that it comprises, at the same time, in combination:
  • - an articulated shoveling arm, the free end of which comprises a shoveling bucket, while the base of its opposite end is secured to the rotary cab;
  • - on the chassis, a horizontal axis on which the base of a lifting loader arm is articulated, the free end of which is fitted with a tool holder capable of receiving, interchangeably, a lifting bucket, or a fork of handling.

Suivant une autre caractéristique de l'invention , le bras élévateur relevable est télescopique , formé de deux éléments coulissant l'un dans l'autre , et actionnés par un vérin de télescopage.According to another characteristic of the invention, the lifting lifting arm is telescopic, formed of two elements sliding one inside the other, and actuated by a telescoping jack.

Suivant une autre caractéristique de l'invention , le moteur thermique et la centrale hydraulique sont placés sur le plancher tournant de la cabine , alors qu'un joint hydraulique tournant à plus de dix passages relie de façon étanche la partie fixe du circuit hydraulique portée par le châssis , et la partie mobile du châssis hydraulique portée par la cabine pivotante , et par le bras de pelletage.According to another characteristic of the invention, the heat engine and the hydraulic unit are placed on the rotating floor of the cabin, while a hydraulic seal rotating with more than ten passages tightly connects the fixed part of the hydraulic circuit carried by the chassis, and the mobile part of the hydraulic chassis carried by the pivoting cabin, and by the shoveling arm.

Suivant une autre caractéristique de l'invention , la partie du circuit hydraulique portée par le châssis actionne par ailleurs , d'une parti , les vérins de stabilisateurs au sol relevables , d'autre part , les moteurs hydrauliques incorporés aux roues de l'engin , dont la transmission est hydrostatique.According to another characteristic of the invention, the part of the hydraulic circuit carried by the chassis also actuates, on the one hand, the lifting stabilizer jacks on the ground, on the other hand, the hydraulic motors incorporated in the wheels of the machine , whose transmission is hydrostatic.

L'engin illustré sur les dessins comprend un châssis 1 , porté par des roues 2 .Le châssis 1 est équipé d'une couronne d'orientation 3 , que surmonte une cabine 4 , si bien que celle-ci peut tourner de 360° , autour de l' axe géométrique de pivotement 5 , défini par la cabine 4 .The machine illustrated in the drawings comprises a chassis 1, carried by wheels 2. The chassis 1 is equipped with an orientation crown 3, which is surmounted by a cabin 4, so that the latter can rotate 360 °, around the geometric pivot axis 5, defined by the cabin 4.

A l'intérieur de la cabine 4 , se trouve un poste de commande , défini par un siège 6 , et un pupitre de pilotage 7 . Par ailleurs , le plancher de la cabine 4 est solidaire d'une centrale hydraulique 8 , comprenant notamment un réservoir d'huile non représenté , un moteur thermique 9 , et deux pompes hydrauliques 10 et 11 .Inside the cabin 4, there is a control station, defined by a seat 6, and a cockpit 7. Furthermore, the floor of the cabin 4 is integral with a hydraulic unit 8, comprising in particular an oil reservoir not shown, a heat engine 9, and two hydraulic pumps 10 and 11.

Le plancher de la cabine 4 est par ailleurs solidaire d'une embase 12 , sur laquelle vient s'ar- ciculer le pied 13 d'un bras de pelletage , dont la tête 14 porte , à son extrémité , un fodet excavateur 15 . Les différents mouvements de l'ensemble articulé 13 , 14 , 15 , sont commandés par des vérins hydrauliques tels que 16 , 17 , 18.The floor of the cabin 4 is also integral with a base 12, on which the foot 13 of a shoveling arm is articulated, the head 14 of which carries, at its end, an excavator fodet 15. The various movements of the articulated assembly 13, 14, 15 are controlled by hydraulic cylinders such as 16, 17, 18.

Par ailleurs , le châssis 1 est pourvu d'un axe d'articulation horizontal 19 , sur lequel est articulé l'élément de pied 20 , d'un bras télescopique relevable 20 , 21 , dont la tête coulissante 21 se termine par un porte-outil orientable 22 . Sur ce porte-outil peut être adapté par exemple :

  • - soit un godet chargeur 23 ( figure 1)
  • - soit une fourche de manutention 24 ( figure 4).
Furthermore, the chassis 1 is provided with a horizontal articulation axis 19, on which the foot element 20 is articulated, with a lifting telescopic arm 20, 21, the sliding head 21 of which ends in a holder. steerable tool 22. On this tool holder can be adapted for example:
  • - either a loader bucket 23 (Figure 1)
  • - or a handling fork 24 (Figure 4).

Le télescopage du bras 20 , 21 est commandé par un vérin hydraulique intérieur 35 Par ailleurs , les mouvements d'inclinaison du porte-outil 22 par rapport à la tête de bras 21 sont commandés par un vérin hydraulique 26 .The telescoping of the arm 20, 21 is controlled by an internal hydraulic cylinder 35 Furthermore, the tilting movements of the tool holder 22 relative to the arm head 21 are controlled by a hydraulic cylinder 26.

Enfin , le châssis 1 comporte deux stabilisateurs 27 , de type connu , dont le relevage est commandé ,lui aussi par des vérins non représentés.Finally, the chassis 1 comprises two stabilizers 27, of known type, the lifting of which is also controlled by jacks not shown.

Le circuit hydraulique de l'engin selon l'invention comprend :

  • - une partie mobile 38 , reliée à la centrale hydraulique 8 , et , comme elle , solidaire du plancher de la cabine tournante 4 ;
  • - une partie fixe 37 , portée par le châssis fixe 1 ;
  • - un joint hydraulique tournant 36 , reliant la partie fixe 37 à la partie mobile 38 .
The hydraulic circuit of the machine according to the invention comprises:
  • - A movable part 38, connected to the hydraulic unit 8, and, like it, secured to the floor of the rotary cab 4;
  • - A fixed part 37, carried by the fixed frame 1;
  • - a rotating hydraulic seal 36, connecting the fixed part 37 to the mobile part 38.

Le joint tournant 36 comporte la plupart du temps un nombre de passages supérieur à dix , par exemple quinze passages .The rotary joint 36 most often includes a number of passages greater than ten, for example fifteen passages.

La partie fixe 37 du circuit hydraulique comprend par exemple :

  • - une canalisation 39 , reliant le pupitre de commande 7 aux vérins non représentés des stabilisateurs relevables 27 ;
  • - une canalisation 40 reliant le pupitre de commande 17 à des moteurs hydrauliques non représentés , incorporés aux roues 2 de l'engin , dont la transmission est hydrostatique ;
  • - une canalisation multiple 41 , reliant le pupitre de commande 7 aux vérins tels que 25 , 26 et 46 , du bras télescopique relevable 20 , 21 .
The fixed part 37 of the hydraulic circuit comprises for example:
  • - A pipe 39, connecting the control desk 7 to the jacks not shown of the lifting stabilizers 27;
  • - A line 40 connecting the control panel 17 to hydraulic motors not shown, incorporated into the wheels 2 of the machine, the transmission of which is hydrostatic;
  • a multiple pipe 41, connecting the control console 7 to the jacks such as 25, 26 and 46, of the lifting telescopic arm 20, 21.

Dans la verion simplifiée illustrée sur la figure 1 , le bras relevable 20 n'est pas télescopique ,mais on peut le relever jusqu'à un angle 43 , dont la valeur maxima est de l'ordre de 60° . Dans ce cas , l'outil de levage qui peut être un godet chargeur 23 ou une fourche de manutention 42 , peut être relevé au-dessus du sol , jusqu'à une hauteur 44 au moins égale à 2,80 mètres .In the simplified version illustrated in FIG. 1, the lifting arm 20 is not telescopic, but it can be raised up to an angle 43, the maximum value of which is of the order of 60 °. In this case, the lifting tool, which can be a loader bucket 23 or a handling fork 42, can be raised above the ground, to a height 44 at least equal to 2.80 meters.

Par contre , lorsque le bras 20 , 21 est télescopique ( figure 5) , l'angle de relevage 43 précité conduit à soulever l'outil 23 ou 42 au-dessus du sol , jusqu' à une hauteur 45 , par exemple de l'ordre de 4,10 mètres.On the other hand, when the arm 20, 21 is telescopic (FIG. 5), the aforementioned lifting angle 43 leads to lifting the tool 23 or 42 above the ground, up to a height 45, for example of the order of 4.10 meters.

Grâce à ces performances , on voit que 1' appareil selon l'invention peut être utilisé à la façon d' un chariot élévateur , ce qui n'était le cas d 'aucun des engins précédemment connus comportant un simple bouclier pousseur travaillant toujours à un niveau proche du sol .Thanks to these performances, it can be seen that the apparatus according to the invention can be used in the manner of a forklift, which was not the case with any of the previously known machines comprising a simple pusher shield always working at a level close to the ground.
