Description

CHARIOT DE TRANSPORT A DEPLACEMENT SECURISE La présente invention concerne le domaine technique général du transport de charges au sens général à l'aide d'un chariot monté sur des roues. Dans l'état de la technique, il a été proposé divers types de chariots adaptés aux nombreuses applications auxquelles de tels chariots sont destinés. Par exemple, il est connu un chariot de transport comportant un châssis présentant à l'avant, un train de roues fixes et à l'arrière un train de roues pivotantes. Un tel chariot est équipé d'un système de freinage intervenant sur les roues. De nombreux systèmes de freinage ont été proposés afin de faciliter l'activation et la désactivation des freins. Toutefois, il s'avère que le montage d'un tel système de freinage conduit à l'obtention d'un chariot relativement complexe et onéreux, et le freinage est utilisé uniquement pour le stationnement du chariot mais pas comme un accessoire de sécurité du chariot au cours de son roulement. The present invention relates to the general technical field of conveying loads in the general sense with the aid of a trolley mounted on wheels. In the state of the art, it has been proposed various types of trolleys adapted to the many applications to which such trolleys are intended. For example, it is known a transport carriage having a frame having at the front, a set of fixed wheels and rear a train of swivel wheels. Such a truck is equipped with a brake system acting on the wheels. Many braking systems have been proposed to facilitate the activation and deactivation of the brakes. However, it turns out that the mounting of such a braking system leads to obtaining a relatively complex and expensive carriage, and the braking is used only for parking the truck but not as a safety accessory of the trolley during his ride.
Pour remédier au problème de la mise en œuvre d'un système de freinage ou de stationnement, il a été proposé un chariot de transport comportant un train de roues fixes à l'arrière, tandis que deux béquilles sont fixées à l'avant du chariot. Un tel chariot de transport est utilisé en combinaison avec un chariot de traction adapté pour soulever le chariot au niveau de l'avant, afin d'assurer le roulement du chariot de transport. Cette solution, telle que décrite notamment par la demande de brevet DE 561268, présente l'inconvénient que toute la charge du chariot est reprise par le chariot de traction. De plus, un tel ensemble présente une instabilité latérale de par la présence d'un seul appui central, d'autant plus accentuée que le chariot est pourvu de charges s'élevant relativement haut.To remedy the problem of the implementation of a braking system or parking, it has been proposed a transport carriage having a set of fixed wheels at the rear, while two crutches are fixed to the front of the trolley . Such a transport trolley is used in combination with a trolley adapted to lift the trolley at the front, to ensure the rolling of the trolley. This solution, as described in particular by patent application DE 561268, has the disadvantage that the entire load of the carriage is taken up by the traction carriage. In addition, such an assembly has a lateral instability due to the presence of a single central support, all the more accentuated that the carriage is provided with loads rising relatively high.
De même, les documents FR 1 105 978 et GB 583725 décrivent un chariot de transport comportant un châssis équipé à une extrémité, d'un train de roues fixes et à l'autre extrémité d'une paire de béquilles et d'un équipage mobile dans le plan vertical. Cet équipage mobile comporte un train de roues pivotantes et un levier d'actionnement permettant de décoller les béquilles du sol lors de l'application d'un effort d'abaissement sur le levier. Un tel chariot de transport présente une instabilité latérale en raison de la présence d'un seul appui central, réalisé par le train de roues pivotantes. De plus, la présence du levier d'actionnement s'étendant sur la hauteur d'un des côtés du chariot limite l'accès au chariot pour les opérations de chargement et de déchargement, et augmente son encombrement.Similarly, the documents FR 1 105 978 and GB 583725 describe a transport carriage comprising a chassis equipped at one end, a set of fixed wheels and at the other end of a pair of crutches and a moving assembly. in the vertical plane. This mobile unit comprises a swivel wheel train and an actuating lever for taking off the crutches from the ground when applying a lowering force on the lever. Such a transport trolley has a lateral instability due to the presence of a single central support, made by the slewing wheel train. In addition, the presence of the actuating lever extending over the height of one side of the carriage limits access to the carriage for loading and unloading operations, and increases its size.
La demande de brevet US 2006/0103092 décrit un chariot de transport comportant un châssis équipé à une extrémité d'un train de roues fixes, et à l'autre extrémité d'une paire de béquilles. A proximité de chaque béquille est monté un équipage mobile verticalement. Chaque équipage mobile comporte une roue et un levier articulé dont un appui pour le pied permet de décoller du sol la béquille voisine. Il est clair qu'un tel chariot ne peut transporter que des charges faibles et ne permet pas d'être arrêté rapidement lors de son roulement.US patent application 2006/0103092 discloses a transport carriage comprising a frame equipped at one end of a set of fixed wheels, and at the other end of a pair of legs. Near each crutch is mounted a vertically movable crew. Each mobile unit has a wheel and an articulated lever, a support for the foot allows to take off the ground nearby crutch. It is clear that such a truck can carry only low loads and does not allow to be stopped quickly when rolling.
La présente invention vise donc à remédier aux inconvénients énoncés ci-dessus en proposant un nouveau chariot de transport adapté pour pouvoir présenter un système de freinage simple et rapide à être mis en œuvre, tout en conservant une parfaite stabilité pour la charge à transporter.The present invention therefore aims to remedy the drawbacks stated above by proposing a new adapted transport carriage to be able to present a simple and fast braking system to be implemented, while maintaining a perfect stability for the load to be transported.
Un autre objet de l'invention vise à proposer un chariot conçu pour interdire le déplacement du chariot par une personne non habilitée, ne possédant pas un outil de traction.Another object of the invention is to provide a carriage designed to prohibit the movement of the carriage by an unauthorized person, not having a traction tool.
Pour atteindre un tel objectif, le chariot de transport un châssis présentant en fonction du sens de déplacement du chariot, une première extrémité avant ou arrière et une deuxième extrémité respectivement arrière ou avant, le châssis étant pourvu à l'une de ses extrémités d'un train de roues fixes et à l'autre de ses extrémités, d'une paire de béquilles et d'un équipage mobile dans le plan vertical et comportant un train de roues pivotantes et un levier d'actionnement, caractérisé en ce que l'équipage mobile est monté sur un axe horizontal supporté par le châssis, de manière que les roues pivotantes occupent d'une part une position escamotée permettant au châssis de reposer sur les béquilles et les roues fixes, en l'absence de l'application d'un effort de soulèvement sur le levier, et d'autre part une position de roulement en présence de l'application sur le levier d'un effort de soulèvement du châssis pour décoller du sol les béquilles en vue d'assurer le roulement du chariot par les roues fixes et pivotantes.To achieve such an objective, the carriage carriage a chassis having, according to the direction of movement of the carriage, a first end front or rear and a second end respectively rear or front, the frame being provided at one of its ends with a set of fixed wheels and at the other end thereof, a pair of crutches and a movable element in the vertical plane and comprising a pivoting wheel train and an operating lever, characterized in that the mobile unit is mounted on a horizontal axis supported by the frame, so that the caster wheels occupy on the one hand a retracted position allowing the frame to rest on the crutches and the fixed wheels, in the absence of the application of a lifting force on the lever, and secondly a rolling position in the presence of the application on the lever of a lifting force of the chassis to take off the ground crutches to ensure the rolling of the truck by the fixed wheels and swivel.
Selon une variante préférée de réalisation, au moins une roue pivotante est montée à proximité de chaque bord longitudinal du châssis. Selon un exemple préféré de réalisation, l'équipage mobile est monté sur un axe horizontal supporté par les béquilles.According to a preferred embodiment, at least one pivoting wheel is mounted near each longitudinal edge of the frame. According to a preferred embodiment, the mobile assembly is mounted on a horizontal axis supported by the stands.
Avantageusement, le levier d'actionnement s'étend sensiblement à proximité d'un bord transversal du châssis.Advantageously, the actuating lever extends substantially near a transverse edge of the frame.
Un autre objet de l'invention est de proposer un ensemble de transport comportant un chariot de transport conforme à l'invention, ainsi qu'un chariot conducteur apte à exercer un effort de soulèvement sur le levier du chariot de transport pour soulever les béquilles du sol et mettre en contact du sol, les roues pivotantes.Another object of the invention is to provide a transport assembly comprising a transport carriage according to the invention, and a conductive carriage adapted to exert a lifting force on the lever of the transport carriage to lift the crutches of the ground and bring in contact with the ground, the swivel wheels.
Avantageusement, le chariot conducteur se présente sous la forme d'un diable.Advantageously, the conductive carriage is in the form of a devil.
Selon un exemple préféré de réalisation, le chariot conducteur comporte un bras de manœuvre monté sur un essieu de roues et prolongé par un nez d'actionnement adapté pour exercer un effort de soulèvement sur le levier du chariot de transport. Selon une autre caractéristique, le bras de manœuvre est pourvu d'une roulette de limitation du mouvement de basculement du bras de manœuvre. Diverses autres caractéristiques ressortent de la description faite ci- dessous en référence aux dessins annexés qui montrent, à titre d'exemples non limitatifs, des formes de réalisation de l'objet de l'invention. La Figure 1 est une vue en élévation d'un exemple de réalisation d'un chariot de transport conforme à l'invention.According to a preferred embodiment, the driver carriage comprises an operating arm mounted on a wheel axle and extended by an actuating nose adapted to exert a lifting force on the lever of the transport carriage. According to another characteristic, the operating arm is provided with a wheel for limiting the tilting movement of the operating arm. Various other features appear from the description given below with reference to the accompanying drawings which show, by way of non-limiting examples, embodiments of the object of the invention. Figure 1 is an elevational view of an exemplary embodiment of a transport carriage according to the invention.
La Figure 2 est une vue latérale du chariot de transport en position de roulement.Figure 2 is a side view of the transport carriage in rolling position.
Les Figures 3 et 4 sont des vues du chariot de transport dans deux phases caractéristiques de mise en œuvre avec un chariot conducteur.Figures 3 and 4 are views of the transport carriage in two typical phases of implementation with a driver carriage.
Tel que cela ressort plus précisément des Figures 1 et 2, l'objet de l'invention concerne un chariot de transport 1 comportant un châssis 2 réalisé, dans l'exemple illustré, sous la forme d'une plateforme. Bien entendu, le châssis 2 peut être différent d'une plateforme et constituer par exemple un conteneur.As is more specifically apparent from Figures 1 and 2, the object of the invention relates to a transport carriage 1 comprising a frame 2 realized, in the illustrated example, in the form of a platform. Of course, the chassis 2 may be different from a platform and constitute for example a container.
Le châssis 2 présente une première extrémité 3 dite avant, en considération du sens de déplacement représenté par la flèche Fl, et une deuxième extrémité 4 dite arrière dans l'exemple illustré. Bien entendu, le chariot 1 peut être déplacé dans un sens contraire au sens Fl, de sorte que les première 3 et deuxième 4 extrémités sont dites respectivement arrière et avant. Le chariot 1 présente ainsi un axe longitudinal X parallèle au sens de déplacement du chariot. Par exemple, le châssis 2 est de forme rectangulaire et possède ainsi deux bords longitudinaux 2i parallèles entre eux et à l'axe longitudinal X et deux bords transversaux 22 parallèles entre eux et perpendiculaires à l'axe longitudinal X.The frame 2 has a first end 3 called before, in consideration of the direction of movement represented by the arrow Fl, and a second end 4 said rear in the illustrated example. Of course, the carriage 1 can be moved in a direction opposite to the direction Fl, so that the first 3 and second 4 ends are respectively said back and front. The carriage 1 thus has a longitudinal axis X parallel to the direction of movement of the carriage. For example, the frame 2 is of rectangular shape and thus has two longitudinal edges 2i parallel to each other and to the longitudinal axis X and two transverse edges 2 2 parallel to each other and perpendicular to the longitudinal axis X.
Le châssis 2 est pourvu à l'une de ses extrémités, par exemple 3, d'un train de roues fixes 5. De préférence, au moins une roue 5 est montée à proximité de chaque bord longitudinal 2i du châssis 2. Le châssis 2 est équipé au niveau de sa deuxième extrémité 4, de béquilles 7. De préférence, une béquille 7 est montée à proximité de chaque bord longitudinal 2± du châssis (Figure 2). Par exemple, les béquilles 7 sont réalisées par des platines s'élevant en saillie sur une hauteur adaptée, de manière qu'en position de contact avec le sol S (Figure 1), le châssis 2 qui est également porté par les roues fixes 5, s'étend sensiblement parallèlement au sol S.The chassis 2 is provided at one of its ends, for example 3, with a set of fixed wheels 5. Preferably, at least one wheel 5 is mounted near each longitudinal edge 2i of the chassis 2. The chassis 2 is equipped at its second end 4, crutches 7. Preferably, a stand 7 is mounted near each longitudinal edge 2 ± of the frame (Figure 2). For example, the crutches 7 are made by plates protruding over a suitable height, so that in position of contact with the ground S (Figure 1), the frame 2 which is also carried by the fixed wheels 5 , extends substantially parallel to the ground S.
Le chariot de transport 1 est pourvu, au niveau de l'extrémité du châssis pourvue des béquilles 7, à savoir 4, d'un équipage 11 mobile dans le plan vertical représenté par le plan de la feuille, à la Figure 1. Cet équipage mobile 11 comporte un train de roues pivotantes 12 et un levier d'actionnement 13. Cet équipage mobile 11 est donc monté autour d'un axe horizontal 15 supporté par le châssis 2 et de préférence par les deux béquilles 7. L'équipage mobile 11 comporte avantageusement deux roues pivotantes 12 s'étendant à proximité chacune d'une béquille 7. Chaque roue 12 est montée pivotante par rapport à une platine 16, de manière que la roue 12 puisse pivoter par rapport à l'axe longitudinal X du chariot. Chaque platine de fixation 16 d'une roue pivotante 12 est articulée autour de l'axe horizontal 15. Il est à noter qu'il peut être prévu de monter des roues jumelées pivotantes sur chaque platine. Ces platines de fixation 16 sont reliées au levier d'actionnement 13. De préférence, les roues pivotantes 12 sont montées de manière à s'étendre vers l'intérieur du chariot, tandis que le levier d'actionnement 13 s'étend sensiblement à proximité d'un bord transversal 22 du châssis 2. Ainsi, tel que cela ressort plus précisément de la Figure 1, l'extrémité libre du levier d'actionnement 13 s'étend sensiblement à l'aplomb du bord transversal 22 du châssis 2. Ainsi, les roues pivotantes 12 s'étendent d'un côté de l'axe 15, en dessous du châssis 2 tandis que le levier d'actionnement 13 s'étend de l'autre côté de l'axe 15, jusqu'au niveau sensiblement du bord transversal 22.The transport carriage 1 is provided, at the end of the frame provided with crutches 7, namely 4, a crew 11 movable in the vertical plane represented by the plane of the sheet, in Figure 1. This crew mobile 11 comprises a swivel wheel train 12 and an actuating lever 13. This movable element 11 is mounted around a horizontal axis 15 supported by the frame 2 and preferably by the two crutches 7. The mobile assembly 11 advantageously comprises two pivoting wheels 12 extending near each of a stand 7. Each wheel 12 is pivotally mounted relative to a plate 16, so that the wheel 12 can pivot relative to the longitudinal axis X of the carriage. Each mounting plate 16 of a swivel wheel 12 is hinged about the horizontal axis 15. It should be noted that it can be expected to mount twin wheels pivoting on each plate. These fixing plates 16 are connected to the actuating lever 13. Preferably, the pivoting wheels 12 are mounted so as to extend towards the inside of the carriage, whereas the actuating lever 13 extends substantially in the vicinity of the carriage. a transverse edge 2 2 of the frame 2. Thus, as is more clearly apparent from Figure 1, the free end of the actuating lever 13 extends substantially in line with the transverse edge 2 2 of the frame 2 Thus, the swivel wheels 12 extend on one side of the axis 15, below the chassis 2 while the actuating lever 13 extends on the other side of the axis 15, until substantially level of the transverse edge 2 2 .
Il doit être compris que l'équipage mobile 11 est monté sur le châssis 2, de manière que les roues pivotantes 12 occupent d'une part une position escamotée (Figure 1) dans laquelle le châssis 2 repose sur le sol S par l'intermédiaire des béquilles 7 et des roues fixes 5. Dans cette position, aucun effort n'est appliqué sur le levier d'actionnement 13, de sorte que le châssis 2 assure l'appui des béquilles 7 sur le sol S. Dans cette position, le chariot 2 occupe une position statique.It should be understood that the mobile unit 11 is mounted on the frame 2, so that the pivoting wheels 12 occupy on the one hand a retracted position (Figure 1) in which the frame 2 rests on the ground S via crutches 7 and fixed wheels 5. In this position, no force is applied to the actuating lever 13, so that the frame 2 ensures the support of the crutches 7 on the ground S. In this position, the carriage 2 occupies a static position.
Afin de déplacer le chariot de transport 1, il convient d'appliquer un effort de soulèvement sur le levier 13 afin de décoller les béquilles 7 du sol, et d'amener les roues pivotantes 12 en contact avec le sol S (Figures 3 et 4). A cet effet, l'équipage mobile 11 pivote ou bascule autour de l'axe horizontal de pivotement ou de basculement 15. Dans la position illustrée à la Figure 4, le chariot 1 est apte à être déplacé et à rouler à l'aide de ses roues 5 et 12.In order to move the transport trolley 1, it is necessary to apply a lifting force on the lever 13 in order to take off the crutches 7 from the ground, and to bring the swivel wheels 12 into contact with the ground S (FIGS. ). For this purpose, the mobile assembly 11 pivots or tilts around the horizontal axis of pivoting or tilting 15. In the position illustrated in FIG. 4, the carriage 1 is able to be moved and rolled with the aid of its wheels 5 and 12.
Selon un exemple préféré d'application, l'effort de soulèvement du châssis 2 est assuré par l'intermédiaire d'un chariot de traction, de poussée ou conducteur 15. De préférence, ce chariot conducteur 15 se présente sous la forme d'un diable indépendant du chariot de transport 1, et comportant un bras de manoeuvre 17 monté sur un essieu de roues 18 au-delà duquel s'étend un nez d'action nement 19 apte à venir coopérer avec le levier d'actionnement 13 de l'équipage mobile. Le nez d'actionnement 19 du diable est adapté pour assurer soit une traction, soit une poussée pour déplacer le chariot 1. De manière classique, le bras de manoeuvre 17 est pivoté (dans le sens contre-horaire dans l'exemple illustré) pour venir placer le nez d'actionnement 19 en dessous du levier d'actionnement 13 (Figure 3). Le bras de manoeuvre 17 est pivoté dans le sens contraire (horaire) afin de soulever le levier 13 en vue de mettre en contact les roues pivotantes 12 avec le sol et de dégager les béquilles 7 du sol S (Figure 4).According to a preferred example of application, the lifting force of the frame 2 is ensured by means of a tractive, push or conductive carriage 15. Preferably, this conductive carriage 15 is in the form of a independent devil of the transport carriage 1, and having an operating arm 17 mounted on a wheel axle 18 beyond which extends an actuating nose 19 adapted to cooperate with the actuating lever 13 of the moving equipment. The actuating nose 19 of the devil is adapted to ensure either traction or thrust to move the carriage 1. In a conventional manner, the operating arm 17 is pivoted (counter-clockwise in the example shown) to move the actuating nose 19 below the actuating lever 13 (Figure 3). The operating arm 17 is rotated in the opposite direction (hourly) in order to lift the lever 13 in order to bring the pivoting wheels 12 into contact with the ground and to disengage the stands 7 from the ground S (FIG. 4).
De préférence, le bras de manoeuvre 17 est pourvu d'une roulette 20 permettant de limiter le mouvement de basculement du bras de manœuvre. Dans cette position, le chariot conducteur 15 permet de déplacer le chariot 1 qui est en contact avec le sol par les quatre roues 5 et 12 assurant une grande stabilité lors de sa phase de roulement. Pour arrêter le chariot 1, il suffit de relâcher l'effort exercé à l'extrémité du bras de manoeuvre 17 de sorte que l'équipage mobile 11 pivote, conduisant à l'escamotage des roues pivotantes 12 et à la mise en contact des béquilles 7 avec le sol S. L'arrêt du chariot 1 est donc immédiat après le relâchement de l'effort de soulèvement sur le levier d'actionnement 13. Il est à noter que le chariot conducteur 15 peut être motorisé.Preferably, the operating arm 17 is provided with a wheel 20 for limiting the tilting movement of the operating arm. In this position, the driver carriage 15 moves the carriage 1 which is in contact with the ground by the four wheels 5 and 12 ensuring high stability during its rolling phase. To stop the carriage 1, it is sufficient to release the force exerted on the end of the operating arm 17 so that the mobile assembly 11 pivots, leading to the retraction of the swivel wheels 12 and to bringing the crutches into contact with each other. 7 with the ground S. The stopping of the carriage 1 is immediate after the release of the lifting force on the actuating lever 13. It should be noted that the driver carriage 15 can be motorized.
L'objet de l'invention présente un autre avantage qui est celui de pouvoir utiliser les platines de fixation des roues pivotantes d'origine d'un chariot et de les remplacer par l'objet de l'invention en utilisant les mêmes points de fixation. The object of the invention has another advantage which is that of being able to use the fixing plates of the original swivel wheels of a carriage and to replace them with the object of the invention by using the same points of attachment. .
