Description

La présente invention concerne, de manière générale, les engins de fonçage destinés à l'enfoncement et à l'extraction d'objets profilés dans le sol par vibration, notamment de tubes ou de pieux.The present invention relates, in general, to driving machines for driving and extracting shaped objects in the ground by vibration, including tubes or piles.

Les engins de ce type sont généralement connus sous le terme de vibrateurs.Gear of this type are generally known as vibrators.

Les vibrateurs sont des équipements vibrants, comprenant une ou plusieurs paires de masselottes excentriques, connues sous l'appellation de masselottes, tournant à grande vitesse et en sens opposé, de sorte que les composantes horizontales des vibrations s'annulent et de manière à obtenir une vibration résultante verticale unidirectionnelle.Vibrators are vibrating equipment, comprising one or more pairs of eccentric weights, known as flyweights, rotating at high speed and in opposite directions, so that the horizontal components of the vibrations cancel each other out so as to obtain resulting unidirectional vertical vibration.

Les vibrateurs sont généralement dotés d'une ou plusieurs pinces qui serrent sur la surface périphérique du tube à enfoncer, transmettant l'intégralité des efforts par friction. Aussi, le dimensionnement de la pince et sa force de serrage doivent être suffisants pour éviter tout glissement.The vibrators are generally provided with one or more clamps which clamp on the peripheral surface of the tube to be driven, transmitting all the forces by friction. Also, the sizing of the clamp and its clamping force must be sufficient to prevent slippage.

Ce mode de serrage est rendu difficile lorsque la génératrice du tube n'est pas droite.This method of tightening is made difficult when the generatrix of the tube is not straight.

Ainsi, les pinces actuelles ne sont pas adaptées pour assurer la préhension de tubes qui présentent une collerette d'extrémité.Thus, the current clamps are not suitable for gripping tubes that have an end flange.

Tel est en particulier le cas dans le domaine des fondations en mer pour l'installation d'éoliennes offshore.This is particularly the case in the field of offshore foundations for the installation of offshore wind turbines.

En effet, pour ce type d'application, les mâts d'éoliennes sont formés de tubes qui sont assemblés au moyen de collerettes d'extrémité. La présence de cette collerette empêche l'utilisation de pinces traditionnelles. En outre, les pinces ne présentent pas une ouverture suffisante pour maintenir correctement la collerette. Enfin, la hauteur limitée de la collerette imposerait des contraintes rédhibitoires pour l'adaptation d'une pince traditionnelle.Indeed, for this type of application, the wind turbine masts are formed of tubes which are assembled by means of end collars. The presence of this collar prevents the use of traditional clamps. In addition, the clamps do not have an opening sufficient to properly maintain the collar. Finally, the limited height of the collar would impose unacceptable constraints for the adaptation of a traditional clamp.

Par ailleurs, les pinces actuelles ont des mors avec des rainures profondes pour éviter tout glissement. Ces rainures pénètrent légèrement dans le tube pour assurer une bonne accroche. Dans le cas de tubes pour la fondation d'éoliennes offshore, la peinture réalisée avant installation ne doit pas être endommagée pour garantir la durée de vie de l'éolienne et les dommages ne peuvent pas être réparés de manière satisfaisante en mer.In addition, the current clamps have jaws with deep grooves to prevent slipping. These grooves penetrate slightly into the tube to ensure a good grip. In the case of pipes for the foundation of offshore wind turbines, the paint made before installation must not be damaged to guarantee the life of the wind turbine and the damage can not be repaired satisfactorily at sea.

Le but de l'invention est donc de pallier ces inconvénients.The object of the invention is therefore to overcome these disadvantages.

L'invention propose ainsi une pince pour vibrateur destinée à l'enfoncement de tubes à collerette dans le sol, comprenant un corps de pince comportant au moins deux mors pour la préhension du tube et un ou plusieurs vérins d'actionnement des mors.The invention thus proposes a vibrator clamp intended for driving flanged tubes into the ground, comprising a gripper body comprising at least two jaws for gripping the tube and one or more actuating jaws for the jaws.

Les mors sont orientés de manière à venir en prise avec la collerette et de manière transversale par rapport à une direction générale de transmission d'efforts d'enfoncement à travers la pince.The jaws are oriented to engage the flange and transverse to a general direction of driving force transmission through the gripper.

L'orientation des mors permet d'obtenir un contact franc sur une surface plane du tube pour une application directe des efforts à transmettre au tube à collerette, cette transmission d'efforts ne dépendant pas des efforts de frottement entre le tube à collerette et les mors de la pince.The orientation of the jaws makes it possible to obtain an open contact on a flat surface of the tube for a direct application of the forces to be transmitted to the flanged tube, this transmission of forces not depending on the frictional forces between the flanged tube and the flanges. jaws of the clamp.

En outre, lorsque la pince est positionnée autour du tube, au moins un mors est positionné en butée sous la collerette du tube, ce qui permet de sécuriser le tube pour éviter toute chute du tube même si le vérin de d'actionnement des mors n'effectue pas de serrage.In addition, when the clamp is positioned around the tube, at least one jaw is positioned in abutment under the flange of the tube, which makes it possible to secure the tube to prevent any fall of the tube even if the actuating cylinder of the jaws does not tighten.

Avantageusement, la pince comporte un support en forme de profilé sur lequel le corps de pince est monté de manière mobile pour positionner latéralement la pince par rapport à la collerette, le corps de pince étant déplaçable sous l'action d'un vérin de positionnement.Advantageously, the clamp comprises a profiled support on which the clamp body is movably mounted to laterally position the clamp relative to the collar, the clamp body being movable under the action of a positioning jack.

Selon encore une autre caractéristique de l'invention, la pince comporte en outre un vérin de solidarisation de la pince au support.According to yet another characteristic of the invention, the clamp further comprises a jack for securing the clamp to the support.

Avantageusement, le vérin de préhension et le vérin de solidarisation sont des vérins à action simultanée.Advantageously, the gripping cylinder and the securing cylinder are simultaneously acting cylinders.

Dans un mode de mise en oeuvre, le support a une forme de profilé en T.In one embodiment, the support has a T-shaped profile.

Dans un mode de réalisation, la pince comporte un mors fixe et un mors mobile sous l'action d'un vérin de préhension.In one embodiment, the clamp comprises a fixed jaw and a movable jaw under the action of a gripping cylinder.

L'invention a également pour objet, selon un deuxième aspect, un vibrateur destiné à l'enfoncement de tubes à collerette dans le sol comprenant un carter vibrant comprenant intérieurement un ensemble de paires de masselottes excentriques entraînées en rotation sous l'action de moyens moteur, ce vibrateur comprenant au moins une pince telle que définie ci-dessus.According to a second aspect, the subject of the invention is also a vibrator intended for driving flanged tubes into the ground, comprising a vibrating casing internally comprising a set of pairs of eccentric flyweights driven in rotation under the action of motor means. , this vibrator comprising at least one clamp as defined above.

D'autres buts, caractéristiques et avantages de l'invention apparaîtront à la lecture de la description suivante, donnée uniquement à titre d'exemple non limitatif, et faite en référence aux dessins annexés sur lesquels :

  • la figure 1 est une vue générale en perspective d'une pince selon l'invention ;
  • les figures 2 et 3 montrent la pince de la figure 1, respectivement en position ouverte et en position de travail, permettant de transmettre une vibration à un tube ;
  • la figure 4 est une vue en coupe de la pince de la figure 1 ; et
  • la figure 5 illustre un exemple d'utilisation d'une pince conforme à l'invention.
Other objects, features and advantages of the invention will appear on reading the following description, given solely by way of nonlimiting example, and with reference to the appended drawings in which:
  • the figure 1 is a general perspective view of a clamp according to the invention;
  • the figures 2 and 3 show the clip of the figure 1 , respectively in the open position and in the working position, for transmitting a vibration to a tube;
  • the figure 4 is a sectional view of the forceps of the figure 1 ; and
  • the figure 5 illustrates an example of use of a clamp according to the invention.

On se référera tout d'abord aux figures 1 à 3 qui montrent un exemple de réalisation d'une pince pour vibrateur, conforme à l'invention, désignée par la référence numérique générale 1.We will first refer to Figures 1 to 3 which show an exemplary embodiment of a clamp for vibrator, according to the invention, designated by the general reference numeral 1.

Une telle pince est destinée à constituer un élément d'un système de serrage destiné à saisir un tube à collerette à enfoncer, directement sur la collerette elle-même.Such a clamp is intended to constitute an element of a clamping system intended to grip a flanged tube to be driven directly on the flange itself.

La pince comporte un corps de pince 2 et un support 3 profilé, ici en T. Le support 3 est doté d'un ensemble de moyens de fixation 4, de type vis, pour assurer la fixation de l'ensemble sur le carter vibrant d'un vibrateur de sorte que les vibrations émises lors du fonctionnement du vibrateur sont transmises au corps de pince 2.The clamp comprises a clamp body 2 and a support 3 profiled, here in T. The support 3 is provided with a set of fastening means 4, screw type, to ensure the attachment of the assembly on the vibrating housing. a vibrator so that the vibrations emitted during operation of the vibrator are transmitted to the clamp body 2.

Dans la suite de la description, on considérera que la direction longitudinale du corps de pince 2, qui s'étend de la zone de raccordement au support 3 jusqu'à l'extrémité opposée du corps, selon l'axe vertical Y, correspond à la direction résultante des vibrations et la direction transversale du corps de pince 2, qui s'étend selon l'axe X, correspond à une direction perpendiculaire à l'axe des vibrations transmises.In the remainder of the description, it will be considered that the longitudinal direction of the clamp body 2, which extends from the connection to the support 3 to the opposite end of the body, along the vertical axis Y, corresponds to the resulting direction of vibration and the transverse direction of the clamp body 2, which extends along the axis X, corresponds to a direction perpendicular to the axis of the vibrations transmitted.

En outre, la pince représentée sur les figures 1 à 3 est représentée en position verticale d'utilisation, l'extrémité du corps de pince située du côté du support 3 étant le côté haut, l'extrémité opposée étant le côté bas.In addition, the clip shown on the Figures 1 to 3 is shown in a vertical position of use, the end of the clamp body located on the side of the support 3 being the high side, the opposite end being the bottom side.

Comme on le voit, le corps de pince 2 comporte une ouverture latérale 5 configurée de manière à recevoir la collerette d'un tube à enfoncer. Il comporte deux mors 6 et 7 dont l'un, à savoir le mors inférieur, est fixe et l'autre est mobile.As can be seen, the clamp body 2 has a lateral opening 5 configured to receive the collar of a push-in tube. It comprises two jaws 6 and 7 of which one, namely the lower jaw, is fixed and the other is movable.

Par ailleurs, le corps de pince 2 est monté déplaçable sur le support profilé 3 sous l'action d'un vérin hydraulique de positionnement 8.Furthermore, the clamp body 2 is movably mounted on the profiled support 3 under the action of a hydraulic positioning cylinder 8.

Ce vérin 8 est activé pour déplacer latéralement la pince et positionner les mors 6 et 7 de part et d'autre de la collerette du tube.This jack 8 is activated to move the clamp laterally and position the jaws 6 and 7 on either side of the collar of the tube.

On se référera également à la figure 4.We will also refer to the figure 4 .

Le mors mobile 7 est fixé sur la tige d'un vérin hydraulique 9. Ce mors 7 est ainsi mobile entre une position ouverte, visible sur la figure 2, choisie de manière qu'il existe un jeu suffisant pour la mise en position de la pince sur le tube et la collerette et une position de travail, visible sur la figure 3.The movable jaw 7 is fixed on the rod of a hydraulic cylinder 9. This jaw 7 is thus movable between an open position, visible on the figure 2 , chosen in such a way that there is sufficient clearance for setting the clamp on the tube and the collar and a working position, visible on the figure 3 .

Un deuxième vérin hydraulique 10 permet de plaquer la pince contre le support 3 en exerçant un effort suffisant pour solidariser la pince et le support en supprimant tout jeu afin de transmettre efficacement les vibrations appliquées par le vibrateur au support 3.A second hydraulic jack 10 makes it possible to press the clamp against the support 3 by exerting sufficient force to secure the clamp and the support by eliminating any play in order to effectively transmit the vibrations applied by the vibrator to the support 3.

On notera la possibilité que les vérins hydrauliques 9 et 10 soient à action simultanée et comportent une chambre de travail commune de manière à assurer le serrage de la pince et sa solidarisation contre le support de manière simultanée.Note the possibility that the hydraulic cylinders 9 and 10 are simultaneous action and comprise a common working chamber so as to ensure the clamping of the clamp and its attachment against the support simultaneously.

On positionnera avantageusement une bague d'arrêt 11 formant butée en appuyant contre le corps de pince de manière à limiter le déplacement vers le haut du vérin de préhension ce qui, sinon, serait susceptible de bloquer la pince en position solidarisée au support.It will advantageously position a stop ring 11 forming a stop by pressing against the clamp body so as to limit the upward movement of the gripping cylinder which otherwise would be likely to block the gripper in position secured to the support.

De même, une deuxième plaque d'arrêt 12 fixée au corps de pince, assure le maintien du vérin 10 de solidarisation.Similarly, a second stop plate 12 fixed to the clamp body, ensures the maintenance of the jack 10 for securing.

En se référant enfin à la figure 5, on voit que la pince qui vient d'être décrite trouve une application particulièrement intéressante pour former un système de serrage comprenant un ensemble de pinces, ici au nombre de huit, en prise avec la collerette C d'un tube T, ces pinces étant utilisées pour transmettre les vibrations d'enfoncement fournies par des vibrateurs (non représentés).Finally referring to the figure 5 it can be seen that the forceps which has just been described finds a particularly advantageous application for forming a clamping system comprising a set of grippers, here eight in number, in engagement with the flange C of a tube T, these grippers being used to transmit driving vibrations provided by vibrators (not shown).

On notera enfin, qu'avantageusement, les mors utilisés pour saisir la collerette peuvent être plats, c'est-à-dire sans rainure profonde afin d'éviter d'endommager la collerette.Finally, note that advantageously, the jaws used to grip the flange can be flat, that is to say without deep groove to prevent damage to the flange.

Comme on le conçoit, en venant serrer la collerette en exerçant un effort de serrage vertical, le maintien du tube ne s'effectue plus par frottement, mais par un contact franc, en butée. Même en cas de défaillance du système de serrage de la pince, le tube ne peut tomber des pinces puisque celles-ci viennent en butée sous la collerette.As it is conceivable, by tightening the flange by exerting a vertical clamping force, maintaining the tube is no longer performed by friction, but by a frank contact in abutment. Even in the event of failure of the clamping system of the clamp, the tube can not fall from the clamps since they abut under the collar.

De telles pinces peuvent ainsi avantageusement être utilisées pour la manutention des tubes avec le vibrateur.Such clamps can thus advantageously be used for handling the tubes with the vibrator.
