Description

La présente invention est relative à des perfec- tionnements apportés aux machines à nettoyer et à décaper les sols au moyen de jets de fluides sous haute pression. The present invention relates to improvements made to machines for cleaning and pickling floors by means of jets of fluids under high pressure.

Les machines actuellement connues et utilisées dans ce but comme celles décrites dans les Brevets français-2 2 454 339 et 2 477 436, ou par exemple celles décrites dans le
Brevet US 3 726 481 et le Brevet Français 2 190 981, qui comportent une série de lances munies de buses, projettent toutes en un mouvement combiné les jets d'eau (ou d'un autre fluide) sous haute pression, lesdits jets produisant un effet de fouet sur les surfaces à décaper. Toutes ces machines, qui ont une action énergique sur les surfaces de nettoyage et qui sont en général très efficaces, ont toutes un grand défaut : le fluide de nettoyage se répand sur le sol, nécessitant parfois une évacuation totale de l'atelier en cours de nettoyage et toujours un balayage ultérieur de l'eau répandue sur le sol.The machines currently known and used for this purpose such as those described in French Patents-2,445,339 and 2,477,436, or for example those described in
US Patent 3,726,481 and French Patent 2,190,981, which comprise a series of lances provided with nozzles, all project in a combined movement the jets of water (or of another fluid) under high pressure, said jets producing a whip effect on the surfaces to be stripped. All these machines, which have an energetic action on the cleaning surfaces and which are generally very effective, all have a great defect: the cleaning fluid spreads on the floor, sometimes requiring a total evacuation of the workshop during cleaning and always a subsequent sweeping of the water spilled on the floor.

La présente invention s'est par conséquent donné pour but de pourvoir à une nouvelle machine à nettoyer et décaper les sols utilisant des fluides (eau, vapeur,etc..) sous haute pression, qui répond mieux aux nécessités de la pratique que les machines visant au meme but antérieurement connues,potamment en ce qu'elle empêche le fluide de se ré- pandre sur le sol et en ce qu'elle réalise une évacuation irmnédiate du fluide après le décapage. The present invention therefore aims to provide a new machine for cleaning and pickling floors using fluids (water, steam, etc.) under high pressure, which better meets the needs of practice than machines aiming at the same goal previously known, potentially in that it prevents the fluid from spreading on the ground and in that it achieves an immediate discharge of the fluid after pickling.

La présente invention a pour objet une machine à nettoyer et à décaper par jets de fluide sous haute pression montée sur chariot mobile et pouvant être éventuellement autoportée, caractérisée en ce qu'elle comprend un premier caisson en forme de cloche dont l'ouverture se trouve un peu au-dessus du sol et à l'intérieur duquel est monté un aspersoir rotatif alimenté en fluide sous haute pression, ledit premier caisson étant entouré d'un deuxième caisson périphérique annulaire muni d'une juPe extérieure d'étanchéité vis-à-vis du sol, ce deuxième caisson annulaire étant pourvu d'un dispositif d'aspiration de fluide et de déchets de décapage. The subject of the present invention is a machine for cleaning and pickling by jets of high pressure fluid mounted on a mobile carriage and possibly being self-supporting, characterized in that it comprises a first bell-shaped box, the opening of which is slightly above the ground and inside which is mounted a rotary sprinkler supplied with fluid under high pressure, said first box being surrounded by a second annular peripheral box provided with an external sealing juPe vis-à-vis screw of the ground, this second annular box being provided with a fluid suction device and pickling waste.

Selon un mode de réalisation avantageux de l'objet de l'invention, l'aspersoir est formé de bras creux disposés radialement sur un joint tournant par l'intermédiaire duquel se fait l'alimentation en fluide sous pression, des buses dirigées vers le sol (ou une autre surface à décaper) étant montées sur lesdits bras, un moteur accouplé au joint tournant entrainant les bras en rotation. According to an advantageous embodiment of the object of the invention, the sprinkler is formed of hollow arms arranged radially on a rotary joint by means of which the fluid under pressure is supplied, nozzles directed towards the ground (or another surface to be stripped) being mounted on said arms, a motor coupled to the rotary joint driving the arms in rotation.

Conformément à l'invention, le dispositif d'aspiration dont est pourvue la machine, comporte une tête d'aspiration montée dans le caisson et reliée par un tuyau à une pompe d'aspiration déversant le liquide aspiré,dans un réservoir.According to the invention, the suction device which is provided with the machine, comprises a suction head mounted in the box and connected by a pipe to a suction pump discharging the sucked liquid, in a tank.

Selon un autre mode de réalisation avantageux de l'objet de l'invention,3a pompe d'aspiration et le réservoir sont montés sur le chariot de la machine.According to another advantageous embodiment of the object of the invention, the suction pump and the reservoir are mounted on the carriage of the machine.

Outre les dispositions qui précèdent l'invention comprend encore d'autres dispositions qui ressortiront de la description qui va suivre.In addition to the preceding arrangements, the invention also comprises other arrangements which will emerge from the description which follows.

L'invention sera mieux comprise à l'aide du complément de description qui va suivre, qui se refère aux dessins annexés dans lesquels
- la figure I est une vue latérale en élévation
d'une machine de décapage selon l'invention
- la figure 2 est la machine représentée à la figure
1 vue de dessus.The invention will be better understood using the additional description which follows, which refers to the accompanying drawings in which
- Figure I is a side elevational view

l'invention.Figure 3 is an axial section of the box of the
machine shown in Figure 1 and
- Figure 4 is a view similar to that of the figu
re 1 of an alternative embodiment in accordance with
the invention.

il doit être bien entendu, toutefois,que ces dessins et les parties descriptives correspondantes sont donnés uniquement à titre d'illustration de l'objet de l'invention dont ils ne constituent en aucune manière une limitation.it should be understood, however, that these drawings and the corresponding descriptive parts are given solely by way of illustration of the subject of the invention of which they do not in any way constitute a limitation.

La machine à décaper selon l'invention, représentée aux dessins, est formée d'un caisson 1 circulaire en forme de cloche renversée dont l'ouverture se trouve à environ un centimètre du sol. Ce caisson porté par quatre roues 2, est entouré d'un caisson annulaire 3 périphérique qui est muni d'une jupe 4 extérieure, en caoutchouc par exemple, cette jupe glissant sur le sol pour assurer l'étanchéité de l'intérieur des caissons par rapport à I'extérieur.  The stripping machine according to the invention, shown in the drawings, is formed of a circular box 1 in the shape of an inverted bell, the opening of which is about one centimeter from the ground. This box carried by four wheels 2, is surrounded by an annular peripheral box 3 which is provided with an outer skirt 4, made of rubber for example, this skirt sliding on the ground to seal the interior of the boxes by outside.

A l'intérieur du caisson 1 est monté un aspersoir rotatif composé par exemple, mais non limitativement, de trois bras 5 au bout de chacun desquels est montée une buse
6 d'aspersion dirigée vers le sol. Cet aspersoir est monté sur un joint 7 tournant sur lequel est branché un tuyau 8 d'alimentation en eau ou autre fluide à haute pression. Ce joint tournant 7 est entraîné en rotation par un moteur 9 qui est couplé au joint tournant 7 par une channe (non représentée) passant sur le pignon 10 de l'arbre de sortie du moteur et sur la roue dentée il entourant le joint tournant.Inside the box 1 is mounted a rotary sprinkler composed for example, but not limited to, of three arms 5 at the end of each of which is mounted a nozzle
6 of spraying directed towards the ground. This sprinkler is mounted on a rotating joint 7 to which is connected a pipe 8 for supplying water or other high pressure fluid. This rotary joint 7 is rotated by a motor 9 which is coupled to the rotary joint 7 by a chain (not shown) passing over the pinion 10 of the motor output shaft and on the toothed wheel surrounding the rotary joint.

Le caisson 3 annulaire est équipé d'une tête î2 d'aspiration destinée à récupérer l'eau répandue sous le caisson 1 ainsi qu'à évacuer les déchets arrachés au sol par les jets d'eau de l'aspersoir rotatif. The annular box 3 is equipped with a suction head î2 intended to recover the water spilled under the box 1 as well as to evacuate the waste torn from the ground by the water jets of the rotary sprinkler.

Cette tête 12 d'aspiration est reliée par un tuyau 13 à une pompe d'aspiration extérieure ou (comme reprEsen- té à la figure 4) à une pompe 14 surmontant un réservoir 15 disposé au-dessus du caisson et destiné d recevoir l'eau et les déchets aspirés. Le chariot est équipé d'un arceau 16 formant poignée de guidage du chariot et qui est assujetti au chariot par deux barres 17 et à la partie supérieure duquel est montée une gâchette 18 de commande d'alimentation en eau, ladite gâchette coupant l'alimentation dès qu'elle est rel chée.  This suction head 12 is connected by a pipe 13 to an external suction pump or (as shown in FIG. 4) to a pump 14 surmounting a reservoir 15 placed above the box and intended to receive the water and waste vacuumed. The carriage is equipped with an arch 16 forming a handle for guiding the carriage and which is secured to the carriage by two bars 17 and at the top of which is mounted a trigger 18 for controlling the water supply, said trigger cutting off the supply as soon as it is released.

Le moteur représenté est, par exemple, un moteur pneumatique qui est relié par un tuyau 19 à une source d'air comprimé
Dans cette machine, l'alimentation en eau se fait par une pompe volumétrique sous une pression variant de O d 500 bars, avec un débit de O à 120 1/minute, la pression et le débit utilisés dépendant de la difficulté du nettoyage.The motor shown is, for example, a pneumatic motor which is connected by a pipe 19 to a source of compressed air
In this machine, the water supply is done by a positive displacement pump at a pressure varying from O d 500 bars, with a flow rate from O to 120 1 / minute, the pressure and the flow rate used depending on the difficulty of cleaning.

L'aspersoir rotatif est entratné par le moteur à une vitesse variant de O à 500 t/minute.The rotary sprinkler is driven by the motor at a speed varying from 0 to 500 rpm.

On pourrait également envisager de supprimer le moteur, une légère inclinaison des buses par rapport au plan vertical des bras imprimant aux bras un mouvement rotatif dû à l'orientation des jets d'eau à la sortie des buses.One could also consider eliminating the engine, a slight inclination of the nozzles relative to the vertical plane of the arms imparting to the arms a rotary movement due to the orientation of the water jets at the outlet of the nozzles.

On remarquera que les moteurs 9 et 14 peuvent être aussi bien électriques que pneumatiques et que le réservoir peut être facilement démontable pour le remplacer par un réservoir vide quand il est plein.It will be noted that the motors 9 and 14 can be both electric and pneumatic and that the tank can be easily dismantled to replace it with an empty tank when it is full.

De même, l'aspersoir peut comporter un nombre quelconque de bras et on peut même envisager plusieurs aspersoirs côte à côte placés dans un caisson de forme ovale par exemple. On peut également envisager l'adjonction d'un réservoir de détergent destiné à être mélangé à l'eau envoyée dans l'aspersoir.Similarly, the sprinkler can include any number of arms and one can even envisage several sprinklers side by side placed in an oval box for example. One can also consider the addition of a detergent tank intended to be mixed with the water sent into the sprayer.

Ainsi que cela ressort de ce qui précède, l'invention ne se limite nullement à ceux de ses modes de réalisation et d'application qui viennent d'être décrits de façon plus explicite ; elle en embrasse au contraire toutes les variantes qui peuvent venir à l'esprit du technicien en la matière, sans s'écarter du cadre, ni de la portée , de la présente invention. As is apparent from the above, the invention is in no way limited to those of its embodiments and of application which have just been described more explicitly; on the contrary, it embraces all the variants which may come to the mind of the technician in the matter, without departing from the framework, or the scope, of the present invention.
