Description

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

La présente invention concerne un nouveau dispositif motorisé pour le décrassage interne, par brossage mécanique, de canalisations de larges sections et de grandes longueurs.The present invention relates to a new motorized device for internal cleaning, by mechanical brushing, pipelines with large sections and great lengths.

ÉTAT DE LA TECHNIQUESTATE OF THE ART

Divers dispositifs sont déjà connus qui, dans la majorité des cas, comportent des brosses motorisées tournant autour d'un axe concentrique avec l'axe de la canalisation.Various devices are already known which, in the majority of cases, include motorized brushes rotating around an axis concentric with the axis of the pipeline.

La reprise du couple résistant de brossage est fonction de la bonne tenue du chariot-support.The resumption of the resistant brushing torque is depending on the good behavior of the support trolley.

Dans certains cas, l'axe de rotation des brosses est perpendiculaire à l'axe de la canalisation, mais les brosses sont alors multiples, avec un dispositif compliqué d'entraínement nécessitant des renvois d'angles peu ou pas compatibles avec une canalisation de faible diamètre.In some cases, the axis of rotation of the brushes is perpendicular to the axis of the pipeline, but the brushes are then multiple, with a complicated device training requiring little or no angles compatible with a small diameter pipe.

BUTS DE L'INVENTIONGOALS OF THE INVENTION

La présente invention vise à éviter les inconvénients de l'état de la technique relevant de la simplicité de construction, tout en ayant la particularité de pouvoir être adaptable aux différentes formes de sections de canalisation existantesThe present invention aims to avoid disadvantages of the state of the art simplicity of construction, while having the particularity to be adaptable to different forms of existing pipeline sections

ELEMENTS CARACTERISTIOUES DE L'INVENTIONCHARACTERISTIC ELEMENTS OF THE INVENTION

Selon l'invention, le dispositif comprend au moins un groupe moto-réducteur, dit de brossage, supporté par un chariot, lui-même équipé d'une part, d'un ou plusieurs groupes moto-réducteurs accouplés à un ou plusieurs dispositifs d'avancement tels que roues, galets crantés, chenilles,... assurant ainsi la translation autonome de l'ensemble dans la canalisation et d'autre part, de moyens de centrage du dispositif tels que roues, galets crantés, chenilles,... montés libres en rotation et situés à l'opposé des systèmes d'avancement, par rapport au plan horizontal passant par l'axe longitudinal de la canalisation.According to the invention, the device comprises at less a motor-reduction unit, called brushing, supported by a cart, itself equipped on the one hand, one or several gearmotors coupled to one or more several advancement devices such as wheels, rollers notches, tracks, ... thus ensuring the translation autonomous of the assembly in the pipeline and other part, centering means of the device such as wheels, notched rollers, tracks, ... mounted free in rotation and located opposite advancement systems, relative in the horizontal plane passing through the longitudinal axis of the pipeline.

Dans cette forme d'exécution, le couple résistant de brossage s'exerce dans un axe perpendiculaire à l'axe de la canalisation et n'agit pas sur le chariot-support : il n'y a pas de risque de rotation du chariot en cas de couple résistant de brossage élevé, même jusqu'au blocage.In this embodiment, the couple resistant to brushing is exercised in a perpendicular axis to the axis of the pipeline and does not act on the support carriage : there is no risk of the carriage rotating in resistance to high brushing torque, even up to blocking.

De plus, un nombre réduit de brosses, en l'occurrence seulement quatre brosses, sont nécessaires pour l'intégralité de la surface interne de la canalisation, en utilisant un dispositif très simple, fiable et installable dans une conduite de diamètre restreint. In addition, a reduced number of brushes, in the occurrence only four brushes, are required for the entire internal surface of the channeling, using a very simple device, reliable and installable in a diameter pipe restricted.

Avantageusement, les moyens de centrage seront mobiles et pourvus de dispositifs à rattrapage de jeu, de sorte à pouvoir d'une part, s'adapter aux différentes sections de canalisation et d'autre part, assurer sur le ou les dispositifs d'avancement, par l'intermédiaire du chariot, une pression suffisante afin d'éviter tout patinage du ou des dispositifs d'avancement sur la paroi interne de la canalisation.Advantageously, the centering means will be mobile and provided with backlash devices, on the one hand, able to adapt to different pipe sections and on the other hand, secure on the or the advancement devices, through the carriage, sufficient pressure to avoid slippage advancement device (s) on the inner wall of the pipeline.

Avantageusement encore, les systèmes d'avancement seront prévus avec possibilité de voie à largeur variable de sorte à rendre le système modulable en fonction de la forme et de l'importance de la section de la canalisation.Advantageously still, the advancement systems will be provided with the possibility of a track with variable width of so as to make the system modular according to the form and the importance of the section of the pipeline.

De préférence, chaque groupe moto-réducteur de brossage comportera au moins une brosse, de forme adaptée à la forme de la canalisation et dont la surface de brossage sera directement liée au nombre de brosses utilisées, de sorte à pouvoir bien entendu atteindre toute la surface interne de la canalisation.Preferably, each geared motor group of brushing will include at least one brush, of a shape adapted to the shape of the pipe and whose brushing surface will be directly related to the number of brushes used, from so of course be able to reach the entire surface internal of the pipeline.

Avantageusement, comme les axes de rotation des brosses seront perpendiculaires à l'axe longitudinal de la canalisation, aucun effet de réaction ne sera induit sur les organes porteurs et moteurs.Advantageously, like the axes of rotation of the brushes will be perpendicular to the longitudinal axis of the channeling, no reaction effect will be induced on the load-bearing and motor components.

De préférence encore, et dans les cas où plusieurs groupes moto-réducteurs de brossage seraient nécessaires, il sera avantageusement prévu de pouvoir les décaler angulairement l'un de l'autre, de sorte d'être assuré que la totalité de la surface intérieure de la canalisation soit bien atteinte par les brosses.Preferably again, and in cases where several motor-driven brushing groups would be necessary advantage will be provided to be able to offset them angularly from each other, so be assured that the entire interior surface of the pipeline either well reached by brushes.

DESCRIPTION DÉTAILLÉE D'UNE PREMIÈRE FORME D'EXECUTION PRÉFÉRÉE DE L'INVENTIONDETAILED DESCRIPTION OF A FIRST FORM OF EXECUTION FAVORITE OF THE INVENTION

La figure 1 représente une forme d'exécution préférée de la présente invention constituée d'un chariot 1, pourvu de roues 2 accouplées à des groupes moto-réducteurs 3 et 4, en position de déplacement longitudinal vers la gauche à l'intérieur d'une canalisation 5.Figure 1 shows an embodiment preferred of the present invention consisting of a carriage 1, provided with wheels 2 coupled to geared motor groups 3 and 4, in the longitudinal displacement position to the left inside a pipe 5.

A l'avant de ce chariot 1 sont adaptés des tronçons de poutrelle 6 de section appropriée aux besoins et accouplés les uns aux autres par des fixations par brides 7 et 8.At the front of this carriage 1 are adapted beam sections 6 of section appropriate to the needs and coupled to each other by fixings by flanges 7 and 8.

Sur chaque de tronçon de poutrelle 6 est fixé, au moins un groupe moto-réducteur de brossage 9 et 10.On each section of beam 6 is fixed, at least one motor-reducing brushing group 9 and 10.

Ces groupes moto-réducteurs de brossage 9 et 10 sont disposés de manière telle que chacun des axes géométriques 11 et 12 de leurs prises de force 13, 14, 15 et 16 traversent perpendiculairement l'axe géométrique 17 correspondant à l'axe géométrique longitudinal de la canalisation 5. These brush-motor 9 and 10 groups are arranged in such a way that each of the axes 11 and 12 of their PTOs 13, 14, 15 and 16 cross the geometric axis 17 perpendicularly corresponding to the longitudinal geometric axis of the pipeline 5.

A chaque prise de force 13, 14, 15 et 16 des groupes moto-réducteurs de brossage 9 et 10 sont respectivement accouplées des brosses 18, 19, 20 et 21 de forme et de nombre adaptés à la forme de la canalisation 5, de sorte à pouvoir bien entendu atteindre toute la surface interne de la canalisation 5.At each PTO 13, 14, 15 and 16 of the brushed motor 9 and 10 groups are brushes 18, 19, 20 and 21 respectively of shape and number adapted to the shape of the pipe 5, so that of course you can reach the full internal surface of the pipe 5.

D'autre part, et afin que la totalité de la surface intérieure de la canalisation 5 soit toujours bien atteinte par les brosses 18, 19, 20 et 21, les axes géométriques 11 et 12 des prises de force 13-14 et 15-16 des groupes moto-réducteurs de brossage respectifs 9 et 10 sont avantageusement décalés angulairement l'un de l'autre.On the other hand, and so that all of the interior surface of line 5 is always good reached by brushes 18, 19, 20 and 21, the axes 11 and 12 of PTOs 13-14 and 15-16 of the respective brushed motor-reduction groups 9 and 10 are advantageously angularly offset one of the other.

Dans le cas de la description de cette forme préférée d'exécution de la présente invention, les deux groupes moto-réducteurs de brossage 9 et 10 entraíne chacun un couple de brosses 18-19 et 20-21 de forme segment sphérique. Ces couples de brosses 18-19 et 20-21 tournent chacun autour de l'axe normal à leur plan sécant, mouillant la surface interne de la canalisation 5. Leurs axes de rotation étant perpendiculaires à l'axe longitudinal 17 de la canalisation 5, aucun effet de réaction n'est induit sur les organes porteurs et moteurs.In the case of the description of this form preferred embodiment of the present invention, both brushed motors 9 and 10 drive groups each a pair of brushes 18-19 and 20-21 in shape spherical segment. These pairs of brushes 18-19 and 20-21 each rotate around the axis normal to their intersecting plane, wetting the internal surface of the pipe 5. Their axes of rotation being perpendicular to the axis longitudinal 17 of line 5, no reaction is not induced on the load-bearing and motor organs.

Chacune des brosses 18, 19, 20 et 21 nettoie un huitième de la partie supérieure de la périphérie interne de la canalisation 5 et un huitième de la partie inférieure de la périphérie de cette même canalisation 5; chaque brosse nettoie donc un quart de la périphérie interne de la canalisation 5. Les deux groupes moto-réducteurs de brossage 9 et 10 sont donc décalés d'un huitième de tour, afin que la totalité de la surface intérieure de la canalisation 5 soit bien atteinte par le brossage. Each of the brushes 18, 19, 20 and 21 cleans a eighth from the top of the inner periphery of line 5 and an eighth of the part lower of the periphery of this same pipe 5; each brush therefore cleans a quarter of the periphery internal of the pipe 5. The two gear-motor groups brushing 9 and 10 are therefore offset by eighth of a turn, so that the entire surface line 5 is well reached by the brushing.

Le dispositif est en outre pourvu d'un système de centrage, constitué d'au moins une roue, galet cranté, chenille... 22, montée à l'opposé des roues, galets crantés, chenilles... 2 d'avancement, par rapport au plan horizontal passant par l'axe longitudinal 17 de la canalisation 5. Cette roue, galet cranté, chenille... 22 est montée libre en rotation sur un axe 23 qui est, d'une part, supporté par un bras 24 oscillant autour d'un axe 25 et d'autre part, maintenu sous pression par l'intermédiaire d'un vérin 26 de sorte que la roue, galet cranté, chenille... 22 est toujours maintenue sous pression contre la paroi interne de la canalisation 5. Il en résulte, par réaction, qu'une pression suffisante est toujours appliquée sur le chariot 5 de manière à éviter tout patinage des roues, galets crantés, chenilles... 2 sur la paroi interne de la canalisation 5 et à rattraper tout jeu éventuel dû à des dénivellations de surface.The device is furthermore provided with a centering, consisting of at least one wheel, notched roller, track ... 22, mounted opposite the wheels, notched rollers, tracks ... 2 of advancement, compared to the horizontal plane passing through the longitudinal axis 17 of the pipe 5. This wheel, notched roller, track ... 22 is mounted free in rotation on an axis 23 which is, on the one hand, supported by a arm 24 oscillating around an axis 25 and on the other hand, kept under pressure by means of a cylinder 26 of so that the wheel, notched roller, track ... 22 is always kept under pressure against the inner wall of the line 5. As a result, by reaction, a pressure sufficient is always applied to the carriage 5 of so as to avoid any slipping of the wheels, notched rollers, tracks ... 2 on the internal wall of the pipe 5 and to make up for any possible play due to uneven area.

De plus, et afin de rendre le dispositif le plus modulable possible en fonction des formes et des dimensions des sections de canalisations 5 à décrasser, il est prévu sur le dispositif de pouvoir ajuster la largeur de voie "X".In addition, and in order to make the device the most modular possible according to shapes and dimensions pipe sections 5 to be scoured, provision is made on the device to be able to adjust the track width "X".

Cet ajustement de la largeur de voie "X" conjugué à l'action de la roue, galet cranté, chenille... 22 permettra ainsi, de garder les axes géométriques 11 et 12 des prises de force 13, 14, 15 et 16 perpendiculaires à l'axe géométrique longitudinal 17 de la canalisation 5 de sorte que l'unité de brossage soit constamment maintenue parfaitement centrée dans la section de la canalisation 5.This adjustment of the track width "X" combined wheel action, notched roller, track ... 22 will allow, to keep the geometric axes 11 and 12 PTOs 13, 14, 15 and 16 perpendicular to the longitudinal geometric axis 17 of the pipe 5 of so that the brushing unit is constantly maintained perfectly centered in the section of the pipeline 5.

En variante selon une autre forme d'exécution préférée de la présente invention il est possible de remplacer les deux groupes moto-réducteurs de brossage par un seul qui tournerait sur lui-même et qui pourrait par exemple être entraíné dans ce mouvement à l'aide d'un dispositif d'accouplement avec le dispositif d'avancement (pignons, cardans, renvois d'angle, réducteurs de vitesse,...);Alternatively according to another embodiment preferred of the present invention it is possible to replace the two geared motor brushing groups with only one which would turn on itself and which could by example being trained in this movement using a coupling device with the advancement device (gears, cardan shafts, angular gearboxes, reduction gears speed,...);
