Abstract
Description
L'invention concerne les anneaux de levage, spécialement pour charge pondéreuse.The invention relates to lifting rings, especially for heavy loads.
L'anneau de levage de l'invention est plus particulièrement conçu pour des charges suspendues requérant des manoeuvres précises de positionnement et d'orientation, telles que des moules d'injection industriels, etc.The lifting eye of the invention is more specially designed for suspended loads requiring precise positioning maneuvers and orientation, such as injection molds industrial, etc.
Les anneaux de levage pivotants classiques comprennent un corps pivotant supportant une manille et un élément d'ancrage constitué par une tige filetée.Classic swivel lifting eyes include a pivoting body supporting a shackle and an element anchor formed by a threaded rod.
De tels anneaux sont décrits notamment dans
WO 90/10803 et GB 2 303 682.Such rings are described in particular in
WO 90/10803 and
La pratique révèle que ces anneaux présentent une série d'inconvénients. Leur point faible (zone de rupture) n'est généralement pas l'anneau mais la jonction entre la partie filetée et la face d'appui de l'anneau sur la charge. Cette constatation se vérifie tant sur les anneaux monoblocs que sur les anneaux articulés (elle s'amplifie d'autant plus lorsque l'anneau n'est pas parfaitement plaqué sur la face d'appui).Practice shows that these rings have a series of drawbacks. Their weak point (rupture zone) is generally not the ring but the junction between the threaded part and the bearing face of the ring on the charge. This finding is true both on the rings monoblocks than on articulated rings (it increases all the more so when the ring is not perfectly plated on the support face).
Par ailleurs, les utilisateurs d'outillages (notamment dans le cas de moules d'injection plastiques) sont souvent gênés par des anneaux qui ne laissent pas beaucoup de place pour passer le crochet de levage, si bien que les prises, les raccords divers, les tuyauteries se font arracher lors de manutentions et plus particulièrement pendant le retournement des pièces manipulées.In addition, tool users (in particular in the case of plastic injection molds) are often hindered by rings that don't leave much room to pass the lifting hook, so that the sockets, miscellaneous fittings, the pipes are torn off when handling and more particularly during turning of the parts handled.
Il existe donc une demande réelle pour éloigner de façon sûre le point d'accrochage de la surface des moules, mais aussi par ailleurs un problème de sécurité, car très souvent les utilisateurs ont recours à des montages de fortune et autres solutions hasardeuses avec des anneaux montés sur des rallonges pour éloigner le point d'accrochage de la face d'appui de la charge.There is therefore a real demand to move away from securely the attachment point of the mold surface, but also a security problem, because users often use montages of fortune and other haphazard solutions with rings mounted on extensions to distance the point for attaching the bearing face of the load.
L'invention résout les problèmes ci-dessus en proposant des anneaux à queue lisse, avec système de retenue comme exposé dans le développé technique ci-après, et rend également possible, grâce au gain de place réalisé, l'adjonction d'une embase permettant des anneaux à fort déport d'une solidité exceptionnelle.The invention solves the above problems by offering smooth tail rings, with retained as described in the technical development below, and also makes it possible, thanks to the space saved, the addition of a base allowing strong rings offset of exceptional solidity.
L'objet de l'invention est un anneau de levage pour charge, comprenant une boucle d'accrochage, un corps pivotant et un élément d'ancrage dans le corps d'une charge dans lequel l'élément d'ancrage est une broche cylindrique lisse. Une rainure périphérique est ménagée près de l'extrémité libre de cette broche, un jonc expansible étant inséré dans ladite rainure. La broche est engagée et verrouillée axialement dans un logement cylindrique solidaire du corps de la charge par le jonc. Le logement cylindrique comprend une deuxième rainure périphérique venant en regard de celle de la broche, dans laquelle le jonc expansible est inséré.The object of the invention is a lifting ring for load, including a hooking loop, a body swivel and an anchor in the body of a load wherein the anchor is a cylindrical pin smooth. A peripheral groove is provided near the free end of this pin, an expandable rod being inserted into said groove. The spindle is engaged and axially locked in a cylindrical housing secured to the body of the load by the rod. Housing cylindrical includes a second peripheral groove coming next to that of the spindle, in which the expandable rod is inserted.
Le jonc expansible est de préférence un anneau élastique fendu, ou bien il comprend une pièce élastique exerçant une poussée vers l'extérieur sur des galets ou des segments, de façon à les engager dans la gorge.The expandable ring is preferably a ring split elastic, or it includes an elastic piece pushing outwards on rollers or segments, so as to engage them in the groove.
La boucle peut faire partie intégrante du corps de l'anneau ou bien passe dans un oeilleton intégrée au corps de l'anneau.The loop can be an integral part of the body of the ring or else passes through an eyelet integrated into the body of the ring.
Suivant un mode de réalisation avantageux, le logement cylindrique dans laquelle le corps pivotant est monté est ménagé dans une embase fixée au corps de la charge. According to an advantageous embodiment, the housing cylindrical in which the pivoting body is mounted is formed in a base fixed to the body of the load.
Le sommet de cette embase peut présenter un déport en avant important par rapport à la surface de la charge, ce qui facilite les manipulations en suspension.The top of this base may have an offset in important before compared to the surface of the load, this which facilitates handling in suspension.
Dans ce cas, il est avantageux que le logement cylindrique traverse l'embase.In this case, it is advantageous that the accommodation cylindrical through the base.
Le logement cylindrique comprend alors , de façon avantageuse, un tronçon de plus grand diamètre du côté du revers de l'embase, un verrou annulaire étant inséré le long de ce tronçon, entre l'embase et la broche, de façon à maintenir le jonc ou ses composants en place.The cylindrical housing then comprises, so advantageous, a section of larger diameter on the side of the back of the base, an annular lock being inserted along of this section, between the base and the spindle, so that hold the rod or its components in place.
La broche peut se prolonger au-delà du revers de l'embase, dans une cavité de diamètre correspondant ménagée dans le corps de la charge, ce qui améliore son centrage et sa tenue.The brooch can extend beyond the reverse of the base, in a cavity of corresponding diameter formed in the body of the load, which improves its centering and her outfit.
Un autre objet de l'invention est un corps d'anneau de levage comme décrit ci-dessus, qui comprend une boucle, une broche cylindrique lisse, une rainure périphérique étant ménagée près de l'extrémité libre de cette broche, un jonc expansible étant inséré dans ladite rainure.Another object of the invention is a ring body of lifting as described above, which includes a loop, a smooth cylindrical spindle, a peripheral groove being formed near the free end of this pin, a rod expandable being inserted into said groove.
Avantageusement, un collier de serrage maintient le jonc comprimé en place préalablement à une insertion de la broche lisse dans un logement approprié.Advantageously, a clamp keeps the compressed rod in place prior to insertion of the smooth spindle in a suitable housing.
Un avantage de l'invention est que l'on peut gagner sur la solidité de l'axe, car, par exemple, une broche lisse de diamètre 48 est plus résistante qu'un filetage M 48, surtout à la jonction avec l'anneau. Il est aisé de renforcer la résistance en passant d'un diamètre de Ø 48 à un diamètre de Ø 56, la résistance se trouvant multipliée par ± 1,8, permettant ainsi d'offrir une capacité d'utilisation en traction à 90° proche de celle d'une traction axiale. Généralement la perte d'efficacité à 90° est de l'ordre de 40 % par rapport à la traction axiale, du fait de la faiblesse au point de jonction sur les anneaux classiques tant monoblocs qu'articulés.An advantage of the invention is that one can gain on the solidity of the axis, because, for example, a smooth spindle of diameter 48 is more resistant than an M 48 thread, especially at the junction with the ring. It is easy to strengthen the resistance from a diameter of Ø 48 to a diameter Ø 56, the resistance being multiplied by ± 1.8, thus making it possible to offer a capacity of use in 90 ° traction close to that of axial traction. Generally the loss of efficiency at 90 ° is of the order of 40% compared to axial traction, due to the weakness at the junction point on conventional rings both monoblock and articulated.
Le coût d'un axe lisse ⊘ 56 est moins élevé que celui d'un axe fileté Ø 48, pourtant de moindre diamètre.The cost of a smooth axis ⊘ 56 is lower than that a Ø 48 threaded axis, yet of smaller diameter.
Un autre avantage est que l'invention résout le problème du serrage (ou des oublis de serrage), car un anneau clipsé ou verrouillé ne peut pas l'être à moitié. Par ailleurs, la capacité au raccordement de la tige avec l'anneau est renforcée.Another advantage is that the invention solves the problem of tightening (or forgetting to tighten), because a ring clipped or locked can not be half. Furthermore, the ability to connect the rod with the ring is reinforced.
L'anneau de levage suivant l'invention offre des valeurs garanties par le constructeur, correspondant à l'esprit de standardisation recherchée notamment par les grands donneurs d'ordres de l'industrie plastique, mais également dans d'autres industries.The lifting ring according to the invention offers values guaranteed by the manufacturer, corresponding to the spirit of standardization sought in particular by major contractors in the plastic industry, but also in other industries.
D'autres particularités et avantages de l'invention
ressortiront de la description ci-après de formes de
réalisations particulières, référence étant faite aux
dessins annexés, dans lesquels
La Fig. 1 est une vue générale de l'anneau de levage de
l'invention composé d'une boucle d'accrochage 2 qui forme
ici une seule pièce avec le corps 4 pivotant. Ce corps 4 se
prolonge vers l'arrière en une broche 6 lisse.Fig. 1 is a general view of the lifting ring of
the invention composed of a
Les axes x et y définissent le sens des sollicitations latérales ou axiales.The x and y axes define the direction of the stresses lateral or axial.
Une rainure périphérique 8 est ménagée dans cette
broche 6, généralement près de l'extrémité libre.A
La broche 6 est insérée dans un logement cylindrique 10
ménagé dans le corps de la charge 12. Une gorge 14 fait le
tour du logement cylindrique 10, à une profondeur par
rapport au plan de la surface 16 de la charge 12
correspondant à la position de la rainure 8 sur la broche 6.
Un jonc expansible 18 est placé dans la rainure de la
broche 6. Le jonc 18 est ici un anneau fendu 19 en acier à
ressort traité dur, au profil étudié pour aider à
l'emmanchement et éviter le refermement éventuel sur lui-même
à l'usage.An
Le jonc 18 est, avant l'insertion, maintenu serré par
un collier de serrage (non représenté). Lorsque la broche 6
est poussée dans le logement cylindrique 10, le jonc 18, qui
présente une légère conicité, de par son élasticité,
commence à rentrer dans ce logement 10. Le collier de
serrage ripe et, lorsque le jonc est entré dans le logement
10, peut être retiré. Il suffit ensuite de pousser l'anneau
1 à fond dans son logement 10 jusqu'à ce que le jonc, venant
en regard de la gorge 14, s'y détende et verrouille ainsi
l'anneau 1.The
Les positions respectives de la gorge et de la rainure
sont calculées pour procurer à la face d'appui 20 de
l'anneau 1 un jeu suffisant pour permettre une libre
rotation de l'anneau 1 par rapport au corps de la charge 12.The respective positions of the groove and the groove
are calculated to provide the support face 20 with
Le diamètre de la broche lisse est bien sûr calculé pour que, même dans sa partie amincie, elle garde une résistance suffisante à la traction axiale. The diameter of the smooth spindle is of course calculated so that, even in its thinned part, it keeps a sufficient resistance to axial traction.
Les Fig. 4a à 4d montrent plus en détail différentes
formes de réalisation possible du jonc expansible. La Fig.
4 a montre l'anneau élastique fendu 19.Figs. 4a to 4d show in more detail different
possible embodiments of the expandable rod. Fig.
4 a shows the split
Lorsque le diamètre de la broche est faible, l'anneau
fendu 19 risque de ne pas avoir une élasticité suffisante.
Dans ce cas, on utilise comme montré dans les Fig. 4b, 4c et
4d une lame ressort 22 enroulée en spirale sur plus d'un
tour. Cette lame 22 est placée sous des galets 24 (Fig. 4b,
4c) ou des segments 26, qu'elle repousse vers l'extérieur.
Pour éviter tout retour vers le centre, le développé de la
lame 22 est calculé pour que ses extrémités viennent bout à
bout après l'expansion. Les galets 24 ou segments 26,
engagés et maintenus dans le fond de la gorge 14, sont en
acier très dur et travaillent en cisaillement en cas de
traction axiale.When the diameter of the spindle is small, the ring
split 19 may not have sufficient elasticity.
In this case, as shown in Figs. 4b, 4c and
4d a
Les Fig. 2 et 3 montrent que l'anneau peut, sans sortir
du cadre de l'invention, présenter des boucles 2 de formes
variées.Figs. 2 and 3 show that the ring can, without coming out
within the scope of the invention,
Sur la Fig. 2, la boucle 2 a la forme d'un maillon
fermé 28, passé dans un oeilleton 30 intégré dans le corps 4
de l'anneau. La traction peut se faire suivant une direction
quelconque entre x et y.In Fig. 2, the
A la Fig. 3, un chaínon intermédiaire 32 est intercalé
entre l'oeilleton 30 et le maillon fermé 28. Le maillon 28
est orientable et crochetable dans le bon sens pour qu'un
crochet se débatte dans un plan parallèle à la face d'appui
16.In Fig. 3, an
Lorsque le corps de la charge présente une paroi mince,
il peut être difficile voire impossible d'y insérer la
broche directement. Dans ce cas, le logement cylindrique 10
est ménagé dans une embase 33, laquelle est fixée soit
directement sur la paroi de la charge, soit sur le revers de
celle-ci, comme montré à la Fig. 5. When the body of the load has a thin wall,
it may be difficult or impossible to insert the
spindle directly. In this case, the
Les Fig. 6, 7 et 8 montrent une forme de réalisation où
la boucle, montée sur une embase 34, présente un fort déport
par rapport à la face d'appui de la charge.Figs. 6, 7 and 8 show an embodiment where
the loop, mounted on a
Ce mode de réalisation est rendu possible par la
résistance élevée conférée par la broche lisse et par le
gain en extension axiale, dû à l'absence de tout mécanisme
de pivotement de la boucle, le corps de l'anneau 1 étant, en
lui-même, pivotant.This embodiment is made possible by the
high resistance conferred by the smooth spindle and the
gain in axial extension, due to the absence of any mechanism
pivoting of the loop, the body of the
En dépit du couple de torsion important créé par le déport de l'anneau, l'ensemble reste à haute résistance.Despite the high torque created by the offset from the ring, the assembly remains at high resistance.
Les vues du dessus (Fig. 7) illustrent la possibilité
de réaliser des embases 34 à fort empattement, boulonnées
sur la face d'appui de la charge. Comme représenté, la
semelle 6 de l'embase 34, en fonction de l'encombrement
souhaité, peut être de forme ronde ou carrée.The views from above (Fig. 7) illustrate the possibility
to make
La broche 6 est retenue soit par un jonc fendu 18, soit
par des galets 24, soit par des segments 26 en acier très
dur, travaillant en cisaillement.
Le logement cylindrique 10 peut, comme représenté à la
Fig. 6, traverser toute la longueur de l'embase 34 et
comprendre un tronçon 40 de plus grand diamètre, ce qui
permet d'insérer par le revers de l'embase 34 un verrou
annulaire 40 qui maintien le jonc 18 ou ses composants
(galets 24 segments 26) en place.The
A la Fig. 8, l'anneau avec embase est boulonné au-dessus
d'une cavité ménagée dans le corps de la charge. Le
diamètre de cette cavité est calculé de façon à pouvoir y
introduire un anneau de centrage 44 qui apporte une sécurité
supplémentaire pour des tractions suivant y.In Fig. 8, the ring with base is bolted above
a cavity in the body of the load. The
diameter of this cavity is calculated so that y
introduce a centering
On notera que la cavité peut être un trou taraudé dans
l'embase 34, ce qui permet de fixer, au choix, un anneau de
levage classique sur le même emplacement.Note that the cavity can be a tapped hole in
