Description

DISPOSITIF DE TRANSPORT ET DE MANUTENTION AUTOMOTEUR.SELF-PROPELLED TRANSPORT AND HANDLING DEVICE.
L'invention concerne un dispositif de transport et de manutention automoteur pour la prise en charge et le remorquage d'une charge, tel qu'un plateau de chargement, une benne ou autre, comportant une structure rigide munie de moyens de roulement ou de glissement au moins dans sa partie arrière, opposée à des moyens d' accrochage équipant sa partie avant et susceptibles de coopérer avec des moyens de remorquage associés audit dispositif, lequel comporte au moins une roue à la fois directrice et motrice.The invention relates to a self-propelled transport and handling device for taking over and towing a load, such as a loading platform, a bucket or the like, comprising a rigid structure provided with rolling or sliding means. at least in its rear part, opposite to hooking means equipping its front part and capable of cooperating with towing means associated with said device, which comprises at least one wheel that is both steer and driving.
La présente invention trouvera son application dans le domaine des engins susceptibles de déplacer, sur des sites d'exploitation industrielle ou similaires, des charges comportant une structure rigide pourvue de moyens de roulement au moins dans sa partie arrière. Ainsi, de telles charges peuvent emprunter la forme de moyens de transport, par exemple celle d'un plateau de chargement, d'une benne ou autre, sachant que la présente invention n'est nullement limitée à une telle applicatio .The present invention will find its application in the field of vehicles capable of moving, on industrial or similar operating sites, loads comprising a rigid structure provided with rolling means at least in its rear part. Thus, such loads can take the form of means of transport, for example that of a loading platform, a bucket or the like, knowing that the present invention is in no way limited to such an application.
L'on connaît, depuis de nombreuses années, ces bennes auxquelles 1 ' on fait appel , tant dans les secteurs industriels que ceux de l'environnement, par exemple dans les déchetteries , et qui, la plupart du temps , sont amenées à contenir des déchets divers .We have known for many years these skips which are used both in the industrial and environmental sectors, for example in recycling centers, and which, most of the time, are brought to contain miscellaneous waste.
La particularité de ces bennes consiste en ce qu'elles comportent, à l'arrière de leur structure rigide, des moyens de roulement sous forme de rouleaux, tandis qu'en partie avant sont ménagés des moyens d' accrochage avec lesquels est à même de coopérer un crochet de manutention venant équiper un engin de transport automoteur on ne peut plus classique. Plus précisément, par l'intermédiaire de ce crochet et desdits moyens d'accrochage, ledit véhicule de transport est à même de soulever, en partie avant, ladite benne pour la tirer progressivement sur son plateau de chargement équipé de rouleaux facilitant la progression de la benne. A noter que la présence en partie arrière de la benne de galets lui permet de se déplacer aisément au sol lorsqu'elle est soulevée par le véhicule de transport, au cours de l'opération de chargement.The peculiarity of these skips consists in that they comprise, at the rear of their rigid structure, rolling means in the form of rollers, while in the front part are provided hooking means with which is able to cooperate a handling hook coming to equip a self-propelled transport vehicle could not be more conventional. More precisely, by means of this hook and said attachment means, said transport vehicle is able to lift, in the front part, said bucket to pull it gradually on its loading platform equipped with rollers facilitating the progression of the bucket. Note that the presence in the rear part of the roller bucket allows it to move easily on the ground when it is lifted by the transport vehicle, during the loading operation.
Evidemment, un tel véhicule de transport, ainsi équipé, représente un investissement non négligeable, en particulier lorsqu'il n'est destiné à véhiculer lesdites bennes que sur le site d'exploitation lui même.Obviously, such a transport vehicle, thus equipped, represents a non-negligible investment, in particular when it is intended to transport said skips only on the operating site itself.
De plus, l'on rencontre d'importantes contraintes de manutention lors de la substitution, par exemple, d'une benne pleine par une benne vide qui doit, obligatoirement, prendre la place de la précédente. En effet, il convient tout d'abord de déplacer la benne pleine et, pour cela, la benne vide doit être déchargée du véhicule de transport. Puis, après avoir retiré la benne pleine, il convient de reprendre la benne vide pour la mettre à son emplacement final. Evidemment, pendant toutes ces manipulations le véhicule de transport et son conducteur sont monopolisés .In addition, there are significant handling constraints when replacing, for example, a full bucket with an empty bucket which must, necessarily, take the place of the previous one. Indeed, it is first necessary to move the full bucket and, for this, the empty bucket must be unloaded from the transport vehicle. Then, after removing the full container, it is necessary to take the empty container back to put it in its final location. Obviously, during all these manipulations, the transport vehicle and its driver are monopolized.
Dans la mesure où de telles bennes sont équipées au moins dans leur partie arrière de moyens de roulement, ceci dans le but de permettre leur chargement sur un véhicule de transport tel que décrit ci dessus, l'on a imagé de motoriser de telles bennes.Insofar as such skips are equipped at least in their rear part with rolling means, this in order to allow their loading on a transport vehicle as described above, it has been imagined to motorize such skips.
Ainsi, dans le document FR-A-1.097.434, il est décrit une machine motrice de poussée et de traction pour déplacer des chariots de charge destinés, notamment, aux services des tuileries, des chantiers de construction, des rampes de chargement, etc Cette machine comporte une colonne de direction verticale que l'on peut faire tourner par un guidon et s'étendant au-dessus de moyens de roulement entraînés par un moteur. En fin de compte, une fois le dispositif associé au chariot de charge l'ensemble constitue un véhicule de charge à plusieurs essieux qui est susceptible d'être dirigé. Il est précisé que la colone de direction sert, intérieurement, au montage de l'arbre moteur et, extérieurement, au montage d'un dispositif de levage comportant une enveloppe de crique pourvue de crochets placés les uns au dessus des autres et destinés à s' engager dans des moyens d' accrochage complémentaires que comporte le chariot de charge.Thus, in document FR-A-1,097,434, a push and pull drive machine is described for moving load carriages intended, in particular, for the services of the tileries, construction sites, loading ramps, etc. This machine comprises a vertical steering column which can be rotated by a handlebar and extending over rolling means driven by a motor. In the end, once the device associated with the load carriage the assembly constitutes a load vehicle with several axles which is capable of being steered. It is specified that the steering column is used, internally, for mounting the motor shaft and, externally, for mounting a lifting device comprising a casing provided with hooks placed one above the other and intended for s 'engage in additional hooking means that includes the load carriage.
Le document US-A-4.321.977 décrit, lui, un véhicule de manutention sensiblement analogue à un véhicule tracteur traditionnel et comportant, sous une cabine de pilotage, des moyens de roulement avant directeurs, ainsi que des moyens de roulement arrière pivotants, par ailleurs montés sur des moyens de levage. En partie arrière, ce véhicule comporte des moyens d'accrochage prévus pour coopérer avec la charge à transporter. Pour la prise en charge d'une benne, ces moyens d' accrochage sont tout particulièrement conçus de manière apte à saisir celle-ci de part et d' autre, à la fois dans sa partie supérieure et dans sa partie inférieure.Document US-A-4,321,977 describes a handling vehicle substantially similar to a traditional tractor vehicle and comprising, under a cockpit, front steering bearing means, as well as pivoting rear bearing means, by elsewhere mounted on lifting means. In the rear part, this vehicle includes attachment means provided to cooperate with the load to be transported. For the handling of a bucket, these hooking means are very particularly designed so as to grip it on both sides, both in its upper part and in its lower part.
Il découle, de cette conception, que ces moyens d'accrochage du véhicule de manutention peuvent coopérer avec ceux complémentaires de la benne que s'ils sont parfaitement positionnés les uns par rapport aux autres et, ceci, au niveau des quatre coins de cette benne.It follows from this design that these means for hooking the handling vehicle can cooperate with those complementary to the bucket only if they are perfectly positioned with respect to each other and, this, at the level of the four corners of this bucket .
Il est encore décrit d' autres modes de réalisation de ces moyens d'accrochage, mais qui, pour autant, ne répondent pas aux contraintes rencontrées dans le domaine.Other embodiments of these attachment means are also described, but which, however, do not meet the constraints encountered in the field.
Ainsi, la présente invention concerne un dispositif de transport et de manutention automoteur pour la prise en charge et le remorquage d'une charge, tel qu'un plateau de chargement, une benne ou autre, comportant une structure rigide munie de moyens de roulement ou de glissement au moins dans sa partie arrière, opposée à des moyens d' accrochage équipant sa partie avant et susceptibles de coopérer avec des moyens de remorquage associés audit dispositif, lequel comporte au moins une roue à la fois directrice et motrice. Ce dispositif est caractérisé en ce que les moyens de remorquage consistent en des moyens prévus aptes à solidariser, sans liberté de mouvement entre eux, ledit dispositif à la charge à remorquer et comportent, d'une part, un crochet en mesure de coopérer avec lesdits moyens d' accrochage de forme complémentaire et, d'autre part, des moyens de préhension latérale qui sont prévus aptes à venir s'accrocher, depuis les côtés latéraux, au niveau de ces moyens d'accrochage de la charge, pour empêcher toute rotation du dispositif automoteur par rapport à cette charge autour d'un axe de pivotement vertical passant sensiblement par le crochet.Thus, the present invention relates to a self-propelled transport and handling device for taking charge and towing a load, such as a loading platform, a bucket or the like, comprising a rigid structure provided with rolling means or sliding at least in its rear part, opposite to hooking means equipping its front part and capable of cooperating with towing means associated with said device, which comprises at least one wheel, both driving and driving. This device is characterized in that the towing means consist of means provided capable of joining, without freedom of movement between them, said device to the load to be towed and comprise, on the one hand, a hook able to cooperate with said hooking means of complementary shape and, on the other hand, lateral gripping means which are provided capable of coming to hang, from the lateral sides, at the level of these load hooking means, to prevent any rotation of the self-propelled device with respect to this load around a vertical pivot axis passing substantially through the hook.
En particulier, on observera que l'action de levage d'une benne au moyen d'un crochet conformément à l'invention conduit à une action de basculement de la benne, par rapport au dispositif de transport, autour d'un axe horizontal passant par ledit crochet, de sorte que cette benne vient se plaquer, en partie inférieure, contre ledit dispositif de transport où elle est maintenue au travers des moyens de préhension latérale.In particular, it will be observed that the action of lifting a bucket by means of a hook in accordance with the invention leads to an action of tilting the bucket, relative to the transport device, around a passing horizontal axis. by said hook, so that this bucket is pressed, in the lower part, against said transport device where it is held through lateral gripping means.
Selon le mode de réalisation avantageux de l'invention, le dispositif automoteur comporte, en dehors de la ou des roues directrices et motrices , des moyens de roulement auxiliaires permettant de garantir sa stabilité et d' autoriser ses déplacements en l'absence de charge remorquée.According to the advantageous embodiment of the invention, the self-propelled device comprises, apart from the steered and driving wheel (s), auxiliary rolling means making it possible to guarantee its stability and to authorize its movements in the absence of towed load .
Quant aux moyens de commande associés à ce dispositif et permettant de gérer son fonctionnement, ils peuvent se présenter sous forme d'un poste de pilotage ménagé au niveau de sa structure, sachant que cette commande peut encore intervenir à distance, soit de manière filaire ou non.As for the control means associated with this device and making it possible to manage its operation, they can be in the form of a cockpit provided at the level of its structure, knowing that this control can still intervene remotely, either by wire or no.
II ressort d'ores et déjà de la description qui précède que le dispositif automoteur, conforme à l'invention, s'avère de conception particulièrement simple et son coût de revient peut être très réduit en comparaison à un véhicule de transport du type utilisé jusqu' à présent pour le déplacement de ces bennes à déchets .It is already apparent from the above description that the self-propelled device according to the invention turns out to be particularly simple design and its cost can be greatly reduced compared to a transport vehicle of the type used until now for moving these waste bins.
Dans ces conditions , sur sites d' exploitation, il représente un outil autrement plus pratique qu'un tel véhicule de transport routier connu, lequel pourra se limiter au transport de ces bennes , en dehors de ces sites .Under these conditions, on operating sites, it represents a tool that is far more practical than such a known road transport vehicle, which may be limited to the transport of these skips, outside these sites.
A noter à ce propos que, contrairement à ces véhicules de transport, un dispositif automoteur, selon l'invention, n'intervenant que sur site d'exploitation, ne nécessite aucune qualification particulière pour assurer sa conduite.Note in this regard that, unlike these transport vehicles, a self-propelled device according to the invention, operating only on the operating site, does not require any particular qualification to ensure its driving.
L' invention sera mieux comprise à la lecture de la description qui va suivre et des dessins joints en annexe illustrant un exemple de réalisation.The invention will be better understood on reading the description which follows and the appended drawings illustrating an exemplary embodiment.

Les figures 6, 7 et 8 illustrent, de manière schématisée, les moyens de commande en direction, sensiblement sur 180°, d'une roue directrice et motrice dudit dispositif automoteur.Figures 6, 7 and 8 illustrate, schematically, the direction control means, substantially over 180 °, of a steering and driving wheel of said self-propelled device.
Tel que représenté dans les figures des dessins ci joints, la présente invention a trait à un dispositif de transport et de manutention automoteur 1 pour la prise en charge et le remorquage d'une charge 2, par exemple sous forme d'un plateau de chargement ou, comme visible dans la figure 1, d'une benne 3, cette énumération n'étant nullement limitative.As shown in the figures of the accompanying drawings, the present invention relates to a self-propelled transport and handling device 1 for taking charge and towing a load 2, for example in the form of a loading platform or, as visible in FIG. 1, of a bucket 3, this enumeration being in no way limiting.
En fait cette charge à transporter comporte nécessairement une structure rigide 4 munie, dans sa partie avant 5, de moyens d' accrochage 6 susceptibles de coopérer avec des moyens de remorquage 7 du. dispositif automoteur 1, tandis que, dans sa partie arrière 8 , cette structure rigide 4 , correspondant à la charge 2 , comporte des moyens de roulement 9 , tout du moins des moyens de glissement.In fact, this load to be transported necessarily comprises a rigid structure 4 provided, in its front part 5, with hooking means 6 capable of cooperating with towing means 7 of the. self-propelled device 1, while, in its rear part 8, this rigid structure 4, corresponding to the load 2, comprises rolling means 9, at least sliding means.
A titre d'exemple, les bennes à déchets répondent, souvent, à la description ci dessus .By way of example, the waste bins often meet the above description.
Pour en revenir au dispositif automoteur 1, celui ci comporte, au moins une roue 10 directrice et motrice, tandis que les moyens de remorquage 1 consistent en des moyens prévus aptes à solidariser, sans liberté de mouvement entre eux, le dispositif automoteur 1 à la charge 2 à remorquer.To return to the self-propelled device 1, this comprises, at least one steerable and driving wheel 10, while the towing means 1 consist of means provided capable of securing, without freedom of movement between them, the self-propelled device 1 to the load 2 to be towed.
En venant, ainsi, solidariser le dispositif automoteur 1 par l'intermédiaire desdits moyens de remorquage 7 à une benne 3, comme décrite ci dessus , au travers des moyens d' accrochage 6 équipant cette dernière, cette benne 3, en venant reposer au sol, d'une part, par ses propres moyens de roulement 9 dans sa partie arrière 8 et, d'autre part, au travers de la roue directrice et motrice 10 dudit dispositif automoteur 1, peut être aisément déplacée et anœuvrée.Coming, thus, to secure the self-propelled device 1 via said towing means 7 to a bucket 3, as described above, through hooking means 6 equipping the latter, this bucket 3, coming to rest on the ground on the one hand, by its own rolling means 9 in its rear part 8 and, on the other hand, through the steering and driving wheel 10 of said self-propelled device 1, can be easily moved and operated.
II convient d'observer qu'au cas où, préalablement à la prise en charge par le dispositif automoteur 1 de la charge 2 , celle-ci est amenée à reposer directement au sol dans sa partie avant 5, ou encore par l'intermédiaire de moyens de roulement qui ne sont pas pivotants, donc non orientables, ledit dispositif automoteur 1 comporte, avantageusement, des moyens 11 pour lever ladite charge dans cette partie avant 5.It should be noted that in the event that, before the load 2 is taken up by the self-propelled device 1, the load 2 is brought to rest directly on the ground in its front part 5, or else by means of rolling means which are not pivotable, therefore non-orientable, said self-propelled device 1 advantageously comprises means 11 for lifting said load in this front part 5.
Préférentiellement, de tels moyens de levage 11 sont associés, directement, aux moyens de remorquage 7 qui, une fois amenés en coopération avec les moyens d'accrochage 6 de ladite charge 2, sont, alors, à même de lever celle ci.Preferably, such lifting means 11 are associated, directly, with the towing means 7 which, once brought into cooperation with the hooking means 6 of said load 2, are, then, able to lift the latter.
Substantiellement, lesdits moyens de remorquage 7 sont conçus de manière adaptée aux moyens d'accrochage 6 dans le but d'obtenir le résultat recherché, c'est à dire de rendre solidaire le dispositif automoteur 1 de la charge 2, sans liberté de mouvement entre eux.Substantially, said towing means 7 are designed in a manner adapted to the hooking means 6 in order to obtain the desired result, that is to say to make the self-propelled device 1 integral with the load 2, without freedom of movement between them.
Ainsi, de tels moyens de remorquage 7 comportent, d'une part, un crochet 12 prévu pour coopérer avec des moyens d' accrochage 10 de forme complémentaire et, d'autre part, des moyens de préhension latérale 13, que l'on voit plus particulièrement représentés dans la figure 4 et qui sont prévus aptes à venir s'accrocher, depuis les côtés latéraux, au niveau de ces moyens d'accrochage 6 de la charge 2. Leur fonction consiste, notamment, à empêcher toute rotation du dispositif automoteur 1 par rapport à cette charge 2 autour d'un axe de pivotement vertical passant, sensiblement, par le crochet 12.Thus, such towing means 7 comprise, on the one hand, a hook 12 intended to cooperate with hooking means 10 of complementary shape and, on the other hand, lateral gripping means 13, which can be seen more particularly represented in FIG. 4 and which are provided capable of being hooked, from the lateral sides, at the level of these hooking means 6 of the load 2. Their function consists, in particular, in preventing any rotation of the self-propelled device 1 with respect to this load 2 around a vertical pivot axis passing, substantially, through the hook 12.
Bien évidemment, le fonctionnement des moyens de levage 11, tout comme celui des moyens de préhension 13 peut être assuré par l'intermédiaire d'organes de commande hydrauliques, tenant compte que la présente invention n'est nullement limitée à telle solution.Obviously, the operation of the lifting means 11, like that of the gripping means 13 can be ensured by through hydraulic control members, taking into account that the present invention is in no way limited to such a solution.
De même, en tant que moyens moteur équipant ce dispositif automoteur 1 , on peut faire appel à un moteur thermique ou électrique pour le fonctionnement, par exemple, d'une unité centrale hydraulique capable d'alimenter, à son tour, le ou les vérins hydrauliques correspondants aux moyens de levage 11 ou encore aux moyens de préhension 13, voire un moteur hydraulique ou électrique associé, de manière connue, à la ou les roues directrices et motrices 10.Likewise, as motor means equipping this self-propelled device 1, it is possible to call upon a thermal or electric motor for the operation, for example, of a hydraulic central unit capable of supplying, in turn, the actuator (s) hydraulics corresponding to the lifting means 11 or also to the gripping means 13, or even a hydraulic or electric motor associated, in known manner, with the steered and driving wheels 10.
Il serait, évidemment, à la portée de l'homme du métier que d'assurer une liaison mécanique directe entre cette ou ces roues directrices et motrices 10 et ledit moteur électrique ou thermique .It would obviously be within the reach of those skilled in the art to provide a direct mechanical connection between this or these steered and driving wheels 10 and said electric or heat engine.
Quant aux moyens de commande 14 associés à ce dispositif automoteur 1, ils peuvent emprunter la forme d'un poste de pilotage 15 ménagé au niveau de sa structure, poste 15 sur lequel peut, éventuellement, se tenir un opérateur, comme visible dans la figure 1.As for the control means 14 associated with this self-propelled device 1, they can take the form of a cockpit 15 formed at the level of its structure, station 15 on which an operator can possibly stand, as visible in the figure 1.
Préférentiellement, ce poste de pilotage 15 est disposé latéralement au niveau de cette structure du dispositif automoteur 1, notamment de manière à permettre une vision latérale totale de la charge 2 lors des déplacements .Preferably, this cockpit 15 is disposed laterally at the level of this structure of the self-propelled device 1, in particular so as to allow total lateral vision of the load 2 during movement.
De tels moyens de commande 14 peuvent encore emprunter la forme d'un simple pupitre de commande susceptible d'être relié, de manière filaire ou encore par l'intermédiaire de moyens de commande à distance du type radio ou similaire, audit dispositif automoteur 1. Une telle conception de ces moyens de commande 14 présente un intérêt tout particulier dans le cadre de l'application d'un tel dispositif automoteur 1 pour le transport et la manutention de charges présentant des dimensions plus réduites .Such control means 14 can also take the form of a simple control console capable of being connected, by wire or even by means of remote control means of the radio type or the like, to said self-propelled device 1. Such a design of these control means 14 is of particular interest in the context of the application of such a self-propelled device 1 for transporting and handling loads having smaller dimensions.
A titre d'exemple, la présente invention est applicable au transport et à la manutention d'un cric roulant pour avion. Un tel cric repose, tant en partie avant qu'en partie arrière, sur des moyens de roulement et bien que ceux se situant en partie avant de ce cric sont pivotants et, donc directeurs, la manipulation de ce dernier s'avère délicate.By way of example, the present invention is applicable to the transport and handling of a rolling jack for aircraft. Such a jack rests, both in the front part and in the rear part, on rolling means and although those located in the front part of this jack are pivoting and, therefore guiding, the handling of the latter proves to be delicate.
En fin de compte, comme cela ressort de l'exemple qui précède, le dispositif automoteur 1, objet de l'invention, n'est nullement limité à des applications pour le transport et la manutention de charges lourdes , telles que des bennes .Ultimately, as is apparent from the above example, the self-propelled device 1, object of the invention, is in no way limited to applications for the transport and handling of heavy loads, such as skips.
Si, comme le laisse entendre la description de ce dispositif automoteur 1 , celui ci peut recevoir plusieurs roues directrices et motrices 10 et, en particulier, il peut être équipé d'un essieu directeur, il ne comporte, selon un mode de réalisation avantageux de l'invention, qu'une seule roue directrice et motrice 10 montée pivotante, comme représenté dans les figures 6 à 8, autour d'un axe de pivotement vertical 16 passant, sensiblement, au niveau de son plan médian.If, as the description of this self-propelled device 1 suggests, it can receive several steered and driving wheels 10 and, in particular, it can be equipped with a steered axle, it does not comprise, according to an advantageous embodiment, the invention, that a single steering and driving wheel 10 pivotally mounted, as shown in Figures 6 to 8, about a vertical pivot axis 16 passing, substantially, at its median plane.
Il convient, à ce sujet, de faire une parenthèse. En effet, lorsqu'il est fait allusion à une roue, si celle ci peut se présenter sous forme d'une seule jante avec un seul pneumatique, elle peut encore être équipée de plusieurs jantes, en particulier de deux, disposées côte à côte et recevant, chacune, un pneumatique.On this subject, it is necessary to make a parenthesis. In fact, when reference is made to a wheel, if the latter can be in the form of a single rim with a single tire, it can also be equipped with several rims, in particular two, arranged side by side and each receiving a tire.
Quoi qu'il en soit, à cette roue sont associés des moyens de commande en direction 17 conçus, préférentiellement, pour soumettre ladite roue 10 à une rotation de plus ou moins 90° par rapport à sa position de référence 18, dans l'axe 19 de la charge 2, correspondant à la figure 6.Anyway, this wheel are associated with direction control means 17 designed, preferably, to subject said wheel 10 to a rotation of more or less 90 ° by relative to its reference position 18, in the axis 19 of the load 2, corresponding to FIG. 6.
Ainsi, lesdits moyens, de commande 17 se présentent sous forme d'un jeu de deux biellettes 20 et 21 articulées entre elles au niveau d'une de leurs extrémités, l'autre extrémité de la biellette 20 étant fixée de manière pivotante sur la chape 22 sur laquelle est montée la roue 10, tandis que la biellette 21 est montée articulée, à son extrémité opposée à la biellette précédente 20, en un point fixe 23 au niveau du dispositif automoteur 1. Au delà de ce point fixe 23 de la structure, cette biellette 21 est, par ailleurs, prolongée par un levier 24 sur lequel vient agir un organe de commande 25, ici représenté sous forme d'un vérin.Thus, said control means 17 are in the form of a set of two links 20 and 21 hinged together at one of their ends, the other end of the link 20 being pivotally fixed on the yoke. 22 on which the wheel 10 is mounted, while the link 21 is mounted articulated, at its end opposite to the preceding link 20, at a fixed point 23 at the self-propelled device 1. Beyond this fixed point 23 of the structure , this link 21 is, moreover, extended by a lever 24 on which acts a control member 25, here shown in the form of a jack.
Une telle conception, permettant de faire pivoter la roue directrice et motrice 10 sensiblement sur 180°, présente l'avantage de faciliter les déplacements de la charge 2. Tout particulièrement, il est possible de la faire pivoter moyennant un rayon de courbure réduit.Such a design, making it possible to pivot the steering and driving wheel 10 substantially over 180 °, has the advantage of facilitating the movement of the load 2. In particular, it is possible to rotate it by means of a reduced radius of curvature.
Comme visible sur les figures 1 à 5, ce dispositif automoteur 1 peut encore recevoir des moyens de roulement auxiliaires 26 définis aptes à lui conférer la stabilité nécessaire pour lui permettre de se déplacer, une fois dissocié d'une charge 2.As can be seen in FIGS. 1 to 5, this self-propelled device 1 can also receive auxiliary rolling means 26 defined capable of giving it the stability necessary to allow it to move, once it has been separated from a load 2.
Préférentiellement, de tels moyens de roulement auxiliaires 26 se présentent sous forme d'un essieu fixe 27 recevant de part et d'autre une roue 28, 29 et situé à l'arrière, ou encore, comme représenté sur ces figures, à l'avant de la ou des roues directrices et motrices 10.Preferably, such auxiliary rolling means 26 are in the form of a fixed axle 27 receiving on either side a wheel 28, 29 and located at the rear, or, as shown in these figures, in front of the driving and driving wheel (s) 10.
Avantageusement, de tels moyens de roulement auxiliaires 26 sont prévus escamotables , c' est à dire de manière à permettre le dégagement de l'appui de leurs roues 28, 29 au sol, une fois le dispositif automoteur 1 solidarisé à la charge 2 par 1 ' intermédiaire des moyens de remorquage 7.Advantageously, such auxiliary rolling means 26 are provided retractable, that is to say so as to allow the release of the support of their wheels 28, 29 on the ground, once the self-propelled device 1 secured to the load 2 by means of the towing means 7.
Ainsi, ce dispositif automoteur 1 reçoit des moyens de relevage 30, par exemple sous forme d'un vérin, prévu en mesure de relever l'essieu 27, comme illustré dans la figure 1 et, bien sûr au contraire, de l'abaisser, notamment lorsque le dispositif automoteur 1 est amené à se déplacer seul. Au travers de tels moyens de relevage 30 et à condition que lesdits moyens de roulement se situent à l'avant de la roue directrice et motrice 10, il est encore possible de faire basculer le dispositif automoteur 1 autour de cette roue 10 pour, en particulier abaisser les moyens de remorquage 7 et les amener, ainsi, à niveau par rapport aux moyens d'accrochage 6 de la charge 2, lorsque celle-ci repose directement au sol.Thus, this self-propelled device 1 receives lifting means 30, for example in the form of a jack, provided capable of raising the axle 27, as illustrated in FIG. 1 and, of course on the contrary, of lowering it, especially when the self-propelled device 1 is caused to move alone. Through such lifting means 30 and provided that said rolling means are located at the front of the steering and driving wheel 10, it is still possible to tilt the self-propelled device 1 around this wheel 10 for, in particular lower the towing means 7 and bring them, so, level with the attachment means 6 of the load 2, when the latter rests directly on the ground.
Tel que cela ressort de la description qui précède, un tel dispositif automoteur 1 présente une conception particulièrement simple, de sorte que son coût de revient est nécessairement réduit. Ainsi, dans une application pour le transport et la manutention de bennes, de type bennes à déchets, un tel dispositif automoteur 1 facilite, grandement, la gestion de ces bennes tenant compte que leur déplacement sur site d'exploitation s'avère d'une très grande aisance. A ce propos, cette gestion peut être assurée par un opérateur ne disposant d'aucune autorisation particulière, tel qu'un permis de conduire pour véhicule de transport.As is apparent from the above description, such a self-propelled device 1 has a particularly simple design, so that its cost is necessarily reduced. Thus, in an application for the transport and handling of skips, of the waste skip type, such a self-propelled device 1 greatly facilitates the management of these skips taking into account that their movement on the operating site proves to be of very easy. In this regard, this management can be provided by an operator who does not have any specific authorization, such as a driving license for a transport vehicle.
Finalement, on remarquera qu'en partie avant 31 de ce dispositif automoteur 1 peuvent être monté un ou plusieurs accessoires, particulièrement utiles sur de tels sites d' exploitation industrielle ou autres.Finally, it will be noted that in the front portion 31 of this self-propelled device 1 can be mounted one or more accessories, particularly useful on such industrial or other operating sites.
Par exemple, à l'avant de ce dispositif automoteur 1 peut être monté une lame chasse-neige. Par ailleurs, le fait qu'il soit équipé, éventuellement, d'une pompe hydraulique pour l'alimentation des différentes commandes hydrauliques, voire du moteur d' entraînement hydraulique de la roue 10 , permet d'envisager de raccorder dans cette partie avant 11 du dispositif automoteur 1 des accessoires à fonctionnement hydraulique, telle qu'une pelle, un dispositif de levage ou autre.For example, at the front of this self-propelled device 1 can be mounted a snowplow blade. Furthermore, the fact that it is possibly equipped with a hydraulic pump for the supply of the various hydraulic controls, or even of the hydraulic drive motor of the wheel 10, makes it possible to envisage connecting, in this front part 11 of the self-propelled device 1, accessories with hydraulic operation, such as a shovel, a lifting or whatever.
Finalement l'on rappellera, une nouvelle fois, que si le dispositif automoteur 1 est illustré et décrit, principalement, dans le cadre d'une application pour le transport et la manutention d'une charge, de type plateau de chargement bennes ou autres, l'on peut encore imaginer sa conception en modèle plus réduit pour transporter et manipuler des charges plus petites, similaires à l'exemple du cric pour avion auquel il a été fait référence plus haut. Finally, it will be recalled, once again, that if the self-propelled device 1 is illustrated and described, mainly, within the framework of an application for the transport and handling of a load, of tipper or other loading platform type, one can still imagine its design in a more reduced model for transporting and handling smaller loads, similar to the example of the aircraft jack to which reference was made above.
