Abstract

Trolley, having one or more wheels (18, 19) and a handle (20) for steering it manually, is designed to carry at least three compressed gas bottles (1, 2, 3): one containing oxygen and two containing different combustible gases, one of which is acetylene. Two of the bottles can be positioned one on top of the other, or they can be mounted side by side. They can be positioned on the trolley or removed independently, and they are fitted with individual pressure or flow control valves.

Description

L'invention porte sur un chariot bi-combustible pour le travail à laThe invention relates to a bi-fuel trolley for working at the

flamme, en particulier le soudage et le coupage thermique.  flame, in particular welding and thermal cutting.

La mise en oeuvre de flammes de prémélange oxy-combustible ou aérocombustible pour le travail des métaux ou autres, tel que soudage, coupage, brasage, formage ou les divers traitements thermiques, est courante dans le domaine industriel.  The use of oxy-fuel or air-fuel premixing flames for metal working or other purposes, such as welding, cutting, brazing, forming or the various heat treatments, is common in the industrial field.

Les outillages à flamme peuvent être alimentés par des bouteilles de gaz io autonomes ou par des chariots porte-bouteilles facilitant le transport des bouteilles de gaz.  Flame tools can be powered by autonomous gas cylinders or by bottle trolleys facilitating the transport of gas cylinders.

L'acétylène est le gaz offrant le plus de possibilités. Cependant, son coût élevé peut en limiter l'usage aux seules applications pour lesquelles il est indispensable et, par ailleurs, il connaît des limitations d'utilisation résultant de son conditionnement particulier qui limite le débit maximum au soutirage et de ses caractéristiques de flamme peu adaptées à la combustion dans un brûleur à air induit.  Acetylene is the gas with the most possibilities. However, its high cost can limit its use to only those applications for which it is indispensable and, moreover, it knows limitations of use resulting from its particular conditioning which limits the maximum flow rate at racking and its low flame characteristics. suitable for combustion in an induced air burner.

Actuellement, les chariots de transport de bouteilles de gaz connus sont dédiés à un type d'alimentation donné et, de ce fait, on peut les classer en trois catégories, à savoir: - les chariots dits oxyacétylène portant une bouteille d'acétylène et une bouteille d'oxygène, et - les chariots dits oxycombustible portant une bouteille d'un gaz combustible autre que de l'acétylène et une bouteille d'oxygène, - les chariots dits aéro , portant uniquement une bouteille de combustible mais nécessitant l'utilisation d'un brûleur ou chalumeau à air induit.  Currently, the known gas bottle transport trolleys are dedicated to a given type of feed and, therefore, they can be classified into three categories, namely: the so-called oxyacetylene trolleys carrying an acetylene bottle and a bottle of oxygen, and - carts known as oxy-fuel containing a fuel gas cylinder other than acetylene and a bottle of oxygen, - carriages called aero, carrying only a fuel bottle but requiring the use of a burner or induced air torch.

Toutefois, le problème qui se pose est que différentes applications peuvent requérir différents gaz notamment pour des raisons physicochimiques.  However, the problem is that different applications may require different gases especially for physicochemical reasons.

Or, la solution la plus classique pour remédier à ce problème est de disposer de deux gaz combustibles, donc à disposer de deux chariots équipés de bouteilles de gaz différents ou d'un chariot oxy-acétylène par exemple et d'une bouteille séparée de propane.  However, the most conventional solution to overcome this problem is to have two combustible gases, so to have two trolleys equipped with different gas cylinders or an oxy-acetylene carriage for example and a separate propane bottle .

En effet, les bouteilles d'acétylène et de propane ayant des dimensions très différentes, un même chariot ne peut pas simplement recevoir soit un type de bouteille, soit l'autre. Autrement dit, un chariot est dédié à un type de bouteille de combustible.  Indeed, the acetylene and propane bottles having very different dimensions, the same carriage can not simply receive either a type of bottle or the other. In other words, a trolley is dedicated to a type of fuel bottle.

On comprend immédiatement qu'une telle solution n'est pas satisfaisante notamment en termes d'ergonomie et de mobilité pour l'utilisateur puisqu'elle l'oblige à transporter plusieurs chariots ou alors un chariot et une ou plusieurs autres bouteilles de gaz séparées.  It is immediately understood that such a solution is unsatisfactory in particular in terms of ergonomics and mobility for the user since it forces him to carry several trolleys or a trolley and one or more other separate gas bottles.

La présente invention vise donc à proposer une solution plus pratique io pour l'utilisateur au problème susmentionné.  The present invention therefore aims to provide a more practical solution for the user to the aforementioned problem.

La solution de l'invention est alors un chariot de transport de plusieurs récipients de gaz sous pression, caractérisé en ce qu'il porte au moins trois récipients de gaz.  The solution of the invention is then a transport trolley of several containers of gas under pressure, characterized in that it carries at least three gas containers.

Selon le cas, le chariot de l'invention peut comprendre l'une ou plusieurs des caractéristiques suivantes: - il porte un premier récipient contenant de l'oxygène, un deuxième récipient contenant un premier gaz combustible formé d'acétylène et un troisième récipient contenant un second gaz combustible différent dudit premier fluide combustible.  Depending on the case, the carriage of the invention may include one or more of the following features: - it carries a first container containing oxygen, a second container containing a first fuel gas formed of acetylene and a third container containing a second fuel gas different from said first fuel fluid.

- deux desdits récipients sont superposés l'un à l'autre.  two of said containers are superimposed on one another.

- plusieurs récipients sont juxtaposés les uns aux autres.  - Several containers are juxtaposed to each other.

- il comporte des moyens de commande de gaz, agencés sur les récipients de gaz, permettant d'assurer une commande du débit et/ou de la pression du gaz délivré par lesdits récipients de gaz.  it comprises gas control means arranged on the gas containers, making it possible to control the flow rate and / or the pressure of the gas delivered by said gas containers.

- les moyens de commande de gaz sont choisis parmi les robinets, les valves et les robinets-détendeurs de gaz.  the gas control means are chosen from taps, valves and gas-regulating valves.

- les récipients sont des bouteilles de gaz comprimé.  the containers are bottles of compressed gas.

- chaque récipient de gaz est démontable indépendamment des autres récipients.  - Each gas container is removable independently of other containers.

- il comporte des moyens de maintien permettant de maintenir les bouteilles de gaz sur ledit chariot, de préférence les moyens de maintien comprennent un bandeau-volet.  - It comprises holding means for holding the gas cylinders on said carriage, preferably the holding means comprise a flap strip.

- il comporte, en outre, une ou plusieurs roues permettant un déplacement par roulage sur le sol dudit chariot portant lesdits récipients de gaz et au moins une poignée de préhension manuelle permettant à l'opérateur de diriger manuellement le déplacement par roulage dudit chariot sur le sol.  - It further comprises one or more wheels allowing a rolling movement on the ground of said carriage carrying said gas containers and at least one manual gripping handle allowing the operator to manually direct the rolling movement of said carriage on the ground.

Autrement dit, la solution proposée consiste en un chariot doté de moyens pour recevoir trois récipients de gaz contenant respectivement de l'oxygène, de l'acétylène et un second combustible, lesdites bouteilles étant équipées de moyens de commande de gaz pour assurer la commande de débit des trois gaz, par exemples des robinets (valves) ou des robinetsdétendeurs de gaz.  In other words, the proposed solution consists of a trolley equipped with means for receiving three gas containers respectively containing oxygen, acetylene and a second fuel, said bottles being equipped with gas control means for controlling the flow of the three gases, for example valves (valves) or gas expansion valves.

io Lesdits moyens de commande de gaz sont aussi choisis de manière à permettre à l'opérateur d'opérer un branchement rapide, simple et sûr de différents chalumeaux, torches et brûleurs devant être utilisés pendant l'opération de soudage ou analogue subséquente.  These gas control means are also selected to allow the operator to operate a quick, simple and secure connection of different torches, torches and burners to be used during the welding operation or the like.

Le second combustible est choisi parmi les gaz conditionnés en phase 15 liquide de type C3 comme le propane, le propylène, le FlamalTM, le TétrèneTM, les mélanges dits MAPP ou C4, comme le butane.  The second fuel is chosen from C3-type liquid-phase gases such as propane, propylene, Flamal ™, TetenTM, so-called MAPP or C4 mixtures, such as butane.

Préférentiellement, l'installation ou l'échange de chacune des bouteilles peut se faire sans démonter les deux autres.  Preferably, the installation or exchange of each of the bottles can be done without disassembling the other two.

Accessoirement, des moyens de mélange permettant d'assurer un mélange contrôlé des deux gaz combustibles, pour doper le gaz liquéfié par exemple, et/ou d'enrichissement de l'air en oxygène pour les brûleurs aérocombustible sont associés à l'ensemble.  Incidentally, mixing means for ensuring a controlled mixture of the two combustible gases, for doping the liquefied gas, for example, and / or for enriching the air with oxygen for the air-fuel burners are associated with the assembly.

L'invention est illustrée sur les figures ci-annexées et détaillée ciaprès.  The invention is illustrated in the accompanying figures and detailed below.

La figure 1 représente un chariot selon l'invention équipé d'une bouteille d'oxygène 1, d'une bouteille d'acétylène 2 et d'une cartouche de gaz liquéfié 3.  FIG. 1 represents a trolley according to the invention equipped with an oxygen bottle 1, an acetylene bottle 2 and a liquefied gas cartridge 3.

La bouteille d'oxygène 1 ayant une hauteur de 0,76 m et la bouteille d'acétylène 2 ayant une hauteur 0,62 m, la cartouche de gaz liquéfié est disposée dans une chambre ménagée sous la bouteille d'acétylène, ce qui permet de mettre les têtes des bouteilles d'oxygène et d'acétylène à la même hauteur.  With the oxygen cylinder 1 having a height of 0.76 m and the acetylene bottle 2 having a height of 0.62 m, the liquefied gas cartridge is placed in a chamber formed under the acetylene bottle, which allows to put the heads of the oxygen and acetylene bottles at the same height.

Comme illustré sur la figure 2, la commande de débit de gaz 15 et la prise de raccordement 16 du gaz liquéfié sont aussi à la hauteur des têtes de bouteilles d'acétylène 2 et d'oxygène 1. Ainsi, tous les organes nécessaires à l'utilisation sont regroupés.  As illustrated in FIG. 2, the gas flow control 15 and the connection port 16 of the liquefied gas are also at the height of the acetylene 2 and oxygen 1 cylinder heads. Thus, all the organs necessary for the use are grouped together.

En variante, comme illustré figure 3, la sortie 17 du gaz liquéfié peut aussi être installée à proximité de la cartouche 3, en particulier dans la paroi du 5 compartiment contenant la cartouche 3.  Alternatively, as illustrated in FIG. 3, the outlet 17 of the liquefied gas may also be installed close to the cartridge 3, in particular in the wall of the compartment containing the cartridge 3.

La fixation des bouteilles d'oxygène et d'acétylène est assurée respectivement par les volets-bandeaux 10, 11 et la fixation de la cartouche de gaz liquéfié par le volet-bandeau 12.  The fixing of the oxygen and acetylene bottles is ensured respectively by the strip-shutters 10, 11 and the fixing of the liquefied gas cartridge by the strip-shutter 12.

Les bouteilles d'oxygène et d'acétylène peuvent être du type à robinet io simple ou de préférence à robinet détendeur intégré.  Oxygen and acetylene cylinders may be of the simple tap type or preferably with integrated pressure reducing valve.

La cartouche de gaz liquéfié peut être équipée d'un robinet ou d'une valve, cette dernière solution étant préférable car elle autorise une connexion rapide sur un connecteur 13 installé à demeure dans le chariot.  The liquefied gas cartridge may be equipped with a valve or a valve, the latter being preferable because it allows a quick connection to a connector 13 permanently installed in the carriage.

Dans ce cas, un organe de commande 14 de type pousse-clapet permet dans une première position dite libre d'assembler ou de séparer cartouche et connecteur et, dans une seconde position de solidariser la cartouche et son connecteur sans pour autant autoriser le passage du gaz en ouvrant la valve.  In this case, a control member 14 of the push-valve type allows in a first so-called free position to assemble or separate cartridge and connector and, in a second position to secure the cartridge and its connector without allowing the passage of the gas by opening the valve.

En variante, illustrée en figure 4, le bandeau-volet 12 comporte une cale 18 qui, lorsque le compartiment est fermé, vient se loger entre le plancher du compartiment et le fond de la cartouche de gaz 3 et comble le jeu nécessaire à l'introduction et à l'extraction de la cartouche. Le chariot peut aussi comprendre un volume de rangement pour disposer les outils et accessoires.  Alternatively, illustrated in Figure 4, the shutter strip 12 has a shim 18 which, when the compartment is closed, is housed between the floor of the compartment and the bottom of the gas cartridge 3 and fills the necessary clearance to the introduction and extraction of the cartridge. The trolley may also include a storage space for arranging the tools and accessories.
