Description
Outil de décapage à moteur hydraulique
On connaît déjà des outils de décapage, tels que des brosses métalliques rotatives, dont l'ou til lui-même est entraîné en rotation par un moteur hydraulique.Stripping tool with hydraulic motor
Stripping tools are already known, such as rotary metal brushes, the tool of which itself is rotated by a hydraulic motor.
Les moteurs adoptés à ce jour sont alimentés en fluide à basse pression dont l'encombrement rend peu maniable l'outil de décapage. De plus, les conduits d'alimentation sont eux mêmes encombrants. The motors adopted to date are supplied with low pressure fluid, the size of which makes the stripping tool difficult to handle. In addition, the supply conduits are themselves bulky.
L'invention a pour objet un tel outil de décapage, mais muni d'un moteur de type hydraulique, dont le rotor est muni à sa périphérie d'une pluralité de godets de réception du fluide d'alimentation du moteur, ce moteur étant analogue à une turbine type "Pelton". The subject of the invention is such a pickling tool, but provided with a hydraulic type motor, the rotor of which is provided at its periphery with a plurality of cups for receiving the supply fluid from the engine, this engine being similar. to a "Pelton" type turbine.
De manière préférée, les avantageuses dispositions suivantes sont adoptées
- chaque godet du rotor est fermé axiales ment sur les deux faces axiales du rotor
- chaque godet est séparé du godet suivant par une paroi dont l'arête supérieure présente un petit évidement dans sa zone médiane
- chaque godet a un fond de forme sphérique.Preferably, the following advantageous arrangements are adopted
- each rotor bucket is axially closed on the two axial faces of the rotor
- each bucket is separated from the next bucket by a wall, the upper edge of which has a small recess in its middle zone
- each bucket has a spherical bottom.
Les avantages de ces dispositions nouvelles résident dans une amélioration de la maniabilité des outils de décapage, et par conséquent aussi dans un accroissement de leurs performances. La rusticité de conception des moteurs, qui n' exclut pas l'obtention d'un bon rendement, est en outre un gage de fiabilité dans le temps. The advantages of these new provisions lie in an improvement in the maneuverability of the pickling tools, and therefore also in an increase in their performance. The rustic design of the engines, which does not preclude obtaining a good performance, is also a guarantee of reliability over time.
L'invention sera mieux comprise, et des caractéristiques secondaires et leurs avantages apparattront au cours de la description d'une réalisation donnée ci-dessous à titre d'exemple. The invention will be better understood, and secondary characteristics and their advantages will become apparent during the description of an embodiment given below by way of example.
Il est entendu que la description et les dessins ne sont donnés qu'à titre indicatif et non limitatif. It is understood that the description and the drawings are given for information only and are not limiting.
Il sera fait référence aux dessins annexés dans lesquels
- la figure 1 est une coupe suivant I-I de la figure 2 d'un outil conforme à l'invention ;
- la figure 2 est une coupe suivant II-II de la figure 1 ; et,
- la figure 3 est une vue agrandie du détail A de la figure 2.Reference will be made to the accompanying drawings in which
- Figure 1 is a section along II of Figure 2 of a tool according to the invention;
- Figure 2 is a section along II-II of Figure 1; and,
- Figure 3 is an enlarged view of detail A in Figure 2.
L'outil de décapage représenté sur les dessins est constitué par un corps 1 sur lequel sont montés, d'une part, un moteur hydraulique 2, d'autre part, des brosses métalliques 3 (au nombre de deux, dont une seule visible sur la figure 2). Chaque brosse 3 est montée à rotation dans un palier 4 du corps 1, cependant que la tête d'entraînement 5 du rotor 6 du moteur 2 est en prise avec une tête correspondante 7 de chaque brosse 3. The stripping tool shown in the drawings consists of a body 1 on which are mounted, on the one hand, a hydraulic motor 2, on the other hand, metal brushes 3 (two in number, only one visible on Figure 2). Each brush 3 is rotatably mounted in a bearing 4 of the body 1, while the drive head 5 of the rotor 6 of the motor 2 is engaged with a corresponding head 7 of each brush 3.
Le rotor 6 du moteur 2 est monté à rotation dans le corps 1 au moyen de deux paliers 8. Ce rotor est constitué par une pluralité de godets 9 régulièrement disposés à sa périphérie radiale, adjacents l'un au suivant et séparés par une paroi 10 sensiblement parallèle à l'axe 17 de rotation,dont la zone médiane comporte un petit évidement 11. Chaque godet 9 est creusé dans le bloc même du rotor 6 par une fraise de forme sensiblement sphérique de sorte que la surface interne 12 du fond de ce godet est elle-même sensiblement sphérique. Par ailleurs, une épaisseur de ma tière non nulle subsiste latéralement au niveau de deux faces axiales 13 de la périphérie du rotor, constituant deux parois 14.Ainsi, le rotor 6 ressemble à celui d'une turbine type -"Pelton", avec cependant pour différence le fait que chaque petit godet est borgne, ne débouchant que par une seule ouverture, et que, par conséquent, liteau sous pression, qui pénètre initialement dans un godet, s'en échappe dans un plan radial, et non latéralement (axialement) comme dans une turbine "Pelton" classique-. The rotor 6 of the motor 2 is rotatably mounted in the body 1 by means of two bearings 8. This rotor is constituted by a plurality of buckets 9 regularly arranged at its radial periphery, adjacent one to the next and separated by a wall 10 substantially parallel to the axis 17 of rotation, the central region of which has a small recess 11. Each bucket 9 is hollowed out in the same block of the rotor 6 by a cutter of substantially spherical shape so that the internal surface 12 of the bottom of this the cup is itself substantially spherical. Furthermore, a non-zero thickness of my material remains laterally at the level of two axial faces 13 of the periphery of the rotor, constituting two walls 14. Thus, the rotor 6 resembles that of a typical turbine - "Pelton", with however the difference is that each small bucket is blind, opening only through a single opening, and that, therefore, pressurized batten, which initially enters a bucket, escapes in a radial plane, and not laterally (axially ) as in a classic "Pelton" turbine.
Le corps 1 constitue pour le roto-r 6 un carter fermé, dans lequel l'eau sous pression (100 à 200 bars) est injectée dans les divers godets, successivement, au moyen d'un injecteur 15. Un conduit d'échappement 16 de l'eau hors du carter est disposé en aval de cet injecteur. The body 1 constitutes for the roto-r 6 a closed casing, into which the pressurized water (100 to 200 bars) is injected into the various cups, successively, by means of an injector 15. An exhaust duct 16 water outside the casing is disposed downstream of this injector.
L'avantage essentiel de l'outil décrit, et plus généralement des outils de décapage similaires, est lié à l'injection d'un fluide haute pression, ce qui permet d'obtenir une plus grande compacité et un poids plus petit, d'où une meilleure mobilité par rapport aux outils antérieurement connus. The essential advantage of the tool described, and more generally similar stripping tools, is linked to the injection of a high pressure fluid, which makes it possible to obtain greater compactness and a smaller weight, where better mobility compared to previously known tools.
De plus, la forme même des godets, et notamment la présence des parois 14, conduit à un encombrement axial également inférieur à celui, aussi bien des turbines type "Pelton" classiques que des moteurs à basse pression antérieurs. In addition, the very shape of the buckets, and in particular the presence of the walls 14, results in an axial size which is also less than that of both conventional "Pelton" type turbines and previous low pressure engines.
L'invention n'est pas limitée à la realisation décrite, mais en couvre au contraire toutes les variantes qui pourraient lui être apportées sans sor- tir de son cadre, ni de son esprit. The invention is not limited to the embodiment described, but on the contrary covers all the variants which could be made to it without departing from its scope or its spirit.
