Description

L'invention concerne un support de liaison des sangles de soutien d'un sacThe invention relates to a support for connecting the support straps of a bag

souple d'essais de charge en suspension.  flexible load tests in suspension.

Pour effectuer des essais de bon fonctionnement des appareils de levage et de manutention, tels que grues, palans, treuils, ponts roulants, en usine ou sur chantier, ou encore sur plate-forme offshore, etc., il est connu d'utiliser de lourdes charges pour reconstituer les conditions d'utilisation normales ou anormales et faire les mesures nécessaires aux essais.  In order to carry out functional tests of lifting and handling equipment, such as cranes, hoists, winches, cranes, in the factory or on site, or on an offshore platform, etc., it is known to use heavy loads to restore normal or abnormal conditions of use and to make necessary measurements for testing.

Toutefois, l'entreposage et le transfert de charges inertes et massives telles que des masses métalliques, aussi bien sur place que d'un site à l'autre, sont 10 particulièrement difficiles et onéreux.  However, the storage and transfer of inert and massive loads such as metal masses, both on-site and site-to-site, are particularly difficult and expensive.

C'est pourquoi on a imaginé d'utiliser des charges sous forme de conteneurs remplis d'eau de telle sorte que le remplissage et le vidage peuvent être faits sur place, lesdits conteneurs étant facilement manipulables à vide avant et après les essais.  It is therefore conceivable to use fillers in the form of containers filled with water so that the filling and emptying can be done on site, said containers being easily manipulated in a vacuum before and after the tests.

Pour améliorer encore l'encombrement, on a imaginé d'utiliser des sacs souples et imperméables comme notamment ceux décrits dans le brevet FR-2 768 225 B1.  To further improve the size, it has been imagined to use flexible and impervious bags such as those described in patent FR-2 768 225 B1.

Dans ce document, on décrit un sac pour essais de charge en suspension comportant une enveloppe imperméable soutenue par des sangles régulièrement réparties dont chacune présente une extrémité supérieure destinée à être reliée à des moyens de suspension du sac et une autre extrémité, dite inférieure, reliée à un moyen de liaison.  In this document, there is described a bag for suspension load tests comprising an impervious envelope supported by regularly distributed straps each having an upper end intended to be connected to the suspension means of the bag and another end, said lower, connected to a connecting means.

En outre, dans un tel dispositif connu, au moins un conduit de remplissage et/ou de vidage, muni d'une vanne d'arrêt, traverse ladite enveloppe dans sa partie 25 inférieure, contrairement à d'autres dispositifs connus.  In addition, in such a known device, at least one filling and / or emptying conduit, provided with a stop valve, passes through said envelope in its lower part, unlike other known devices.

Dans ce dispositif comme dans tous les dispositifs connus jusqu'à présent, le moyen de liaison des sangles de soutien disposé sous le sac, se présente sous la forme d'un anneau, encore appelé, selon un terme de la marine, estrope, les sangles étant raccordées à ladite estrope au moyen de boucles ou similaire.  In this device, as in all the devices known hitherto, the connecting means of the support straps disposed under the bag, is in the form of a ring, also called, according to a term of the navy, strop, the straps being connected to said strop by means of loops or the like.

Un tel moyen de liaison présente de nombreux inconvénients et notamment, il ne peut empêcher le déplacement des sangles les unes par rapport aux autres, lesquelles doivent être réajustées régulièrement.  Such a connecting means has many disadvantages and in particular, it can not prevent the movement of the straps relative to each other, which must be readjusted regularly.

De plus, du fait de cette liaison, les sangles forment un ensemble (appelé panier de sangles) et nécessitent par exemple un démontage complet pour en 35 changer seulement une.  In addition, because of this connection, the straps form a set (called basket straps) and require for example a complete disassembly to change only one.

De surcroît, dans le cas du brevet précité FR-2 768 225 B1, l'estrope est disposée dans un logement spécial d'une pièce rigide ce qui rend encore plus difficile son accès. Enfin dans ce cas, la pièce logeant l'estrope et les moyens de vidage et/ou de remplissage étant disposés sous le sac, le délestage du sac, c'est-à-dire la dépose au sol du sac encore suspendu, est délicat, même si l'on a prévu dans ce cas d'éventuels pieds rapportés.  In addition, in the case of the aforementioned patent FR-2 768 225 B1, the strop is arranged in a special housing of a rigid part which makes it even more difficult access. Finally, in this case, the piece housing the strop and emptying means and / or filling being arranged under the bag, unloading the bag, that is to say, the removal of the bag still suspended, is delicate , even if in this case there are any feet reported.

Pour résoudre ces problèmes et en outre permettre une meilleure répartition de la charge, l'invention propose un support de liaison des sangles de soutien d'un sac souple d'essais de charge en suspension du type mentionné ci-avant et comportant donc une enveloppe imperméable soutenue par lesdites sangles régulièrement réparties dont chacune présente une extrémité supérieure destinée à être reliée à des moyens de suspension du sac et une autre extrémité, dite inférieure, reliée audit support de liaison, tandis qu'au moins un conduit de remplissage et/ou de vidage, muni d'une vanne d'arrêt, traverse ladite enveloppe dans sa partie inférieure, ledit support étant notamment remarquable en ce qu'il comporte une couronne rigide qui est munie de moyens d'accrochage régulièrement répartis sur son pourtour, destinés au raccordement individuel des extrémités de chaque sangle, tandis que sensiblement au centre de ladite couronne est aménagé le conduit de remplissage et/ou de vidage, un espace étant aménagé dans ledit support sous le conduit pour loger notamment la vanne d'arrêt. On comprend qu'ainsi chaque sangle devient véritablement individuelle.  To solve these problems and furthermore allow a better distribution of the load, the invention proposes a connection support of the support straps of a flexible bag of suspended load tests of the type mentioned above and thus comprising an envelope impervious supported by said regularly distributed straps each having an upper end intended to be connected to the suspension means of the bag and another end, said lower, connected to said connecting support, while at least one filling duct and / or emptying, provided with a stop valve, through said envelope in its lower part, said support being particularly remarkable in that it comprises a rigid ring which is provided with fastening means regularly distributed around its periphery, intended for the individual connection ends of each strap, while substantially in the center of said crown is arranged the filling conduit e and / or emptying, a space being arranged in said support under the conduit to house including the stop valve. We understand that each strap becomes truly individual.

Avantageusement dans ce cas, la couronne rigide comporte un piétement incorporé et par exemple, le piétement est constitué de plusieurs pieds solidaires ou fixés à la couronne tandis que l'espace pour loger notamment la vanne d'arrêt, est délimité par lesdits pieds.  Advantageously in this case, the rigid crown comprises an incorporated base and for example, the base consists of several feet integral or fixed to the crown while the space for housing including the stop valve, is delimited by said feet.

Selon un mode de réalisation, les pieds sont réunis et recouverts pardessous par une plaque.  According to one embodiment, the feet are joined and covered below by a plate.

L'invention concerne en outre bien sûr aussi un sac pour essais de charge en suspension, équipé d'un support tel que décrit ci-avant.  The invention furthermore of course also relates to a bag for suspension load tests, equipped with a support as described above.

L'invention sera bien comprise à la lecture de la description qui va suivre et 30 qui se réfère aux dessins annexés dans lesquels: la figure 1 schématise en élévation un sac muni d'un support selon l'invention, - la figure 2 est une vue de dessous du sac de la figure 1, - la figure 3 est une vue de dessous du support selon l'invention, - la figure 4 est une coupe schématique du support selon la ligne IV-IV de la 5 figure 3, Le sac 1 représenté sur les figures 1 et 2 est constitué d'une enveloppe souple et imperméable 2 soutenue par des sangles 3 de reprise d'efforts, régulièrement réparties, et dont chacune présente une extrémité supérieure destinée à être reliée à des moyens de suspension du sac comportant par exemple ici une manille 4 et un palonnier 4'.  The invention will be better understood on reading the description which follows and which refers to the appended drawings in which: FIG. 1 schematizes in elevation a bag provided with a support according to the invention, FIG. FIG. 3 is a bottom view of the support according to the invention; FIG. 4 is a diagrammatic section of the support along the line IV-IV of FIG. 1 shown in Figures 1 and 2 consists of a flexible and impervious envelope 2 supported by straps 3 of force recovery, regularly distributed, each having an upper end to be connected to the suspension means of the bag comprising for example here a shackle 4 and a rudder 4 '.

Les autres extrémités des sangles sont reliées chacune individuellement à un support 5 commun de liaison qui est disposé sous le sac.  The other ends of the straps are each individually connected to a common connecting support which is disposed under the bag.

Le support 5, comme le montrent plus en détail les figures 3 et 4, comporte 15 une couronne 6 pourvue de moyens d'accrochage tels qu'ici des oeillets 7 ménagés régulièrement sur le pourtour de la couronne 6.  The support 5, as shown in more detail in FIGS. 3 and 4, comprises a ring 6 provided with attachment means such as here eyelets 7 arranged regularly around the periphery of the ring 6.

Les oeillets 7 sont prévus pour raccorder chacun l'extrémité correspondante d'une sangle 3 pourvue à cet effet d'un moyen conjugué sous forme, par exemple, d'un anneau 8 ou manille, ou similaire.  The eyelets 7 are provided to connect each the corresponding end of a strap 3 provided for this purpose with a conjugate means in the form, for example, of a ring 8 or shackle, or the like.

De la sorte, chaque sangle 3 est raccordée à un oeillet spécifique 7 de la couronne 6, rendant ladite sangle indépendante des autres.  In this way, each strap 3 is connected to a specific eyelet 7 of the ring 6, making said strap independent of the others.

La couronne 6 est traversée par un conduit 9 qui est raccordé de manière étanche par l'une de ses extrémités au fond de l'enveloppe 2 du sac dans laquelle il débouche, au moyen par exemple d'un écrou de serrage 10 et d'un ensemble 11 joint- contre joint.  The ring 6 is traversed by a conduit 9 which is sealingly connected at one of its ends to the bottom of the casing 2 of the bag into which it opens, by means of, for example, a clamping nut 10 and a set 11 seal- against seal.

A l'extrémité du conduit 9 opposée à l'enveloppe 2, est aménagée une vanne d'arrêt 12 pour le remplissage et le vidage, laquelle vanne est par exemple reliée à un tuyau T comme représenté sur la figure 2.  At the end of the duct 9 opposite the casing 2, there is arranged a stop valve 12 for filling and emptying, which valve is for example connected to a pipe T as shown in FIG.

Comme le montre bien la figure 4, la vanne 12 est logée dans un espace 30 situé sous la couronne 6.  As shown in FIG. 4, the valve 12 is housed in a space 30 situated under the crown 6.

L'espace dans lequel est aménagée la vanne 12 est notamment délimité par un piétement du support constitué par plusieurs pieds 13 représentés ici au nombre de quatre, mais il pourrait y en avoir seulement trois ou plus de quatre et en particulier huit.  The space in which the valve 12 is arranged is defined in particular by a base of the support consisting of several feet 13 represented here in number of four, but there could be only three or more than four and in particular eight.

Les pieds 13 sont, par exemple, formés d'une seule pièce avec la couronne 6 ou bien ils sont fixés sur celle-ci, par exemple par soudage.  The feet 13 are, for example, formed in one piece with the ring 6 or they are fixed thereto, for example by welding.

En outre, dans ce mode de réalisation, les pieds 13 sont réunis entre eux et recouverts à leur extrémité inférieure par une plaque 14 ajourée ou non pour 5 notamment des problèmes de poids.  In addition, in this embodiment, the feet 13 are joined together and covered at their lower end by a plate 14 perforated or not including 5 weight problems.

Outre les avantages obtenus comme déjà dit, par un raccordement individuel de chaque sangle, un support selon l'invention permet de créer un véritable support de délestage, ainsi qu'un logement pour notamment une vanne d'arrêt mais aussi pour éventuellement d'autres accessoires, et sans aucune saillie vers l'extérieur. io  In addition to the advantages obtained, as already mentioned, by an individual connection of each strap, a support according to the invention makes it possible to create a real load-shedding support, as well as a housing for a stop valve in particular, but also for possible others. accessories, and without any protrusion to the outside. io
