Abstract

The lifting ring has a body comprising a threaded part 1 which is continued by a support part 2 and a head 3 of larger diameter. Bearing on the support part 3 is an intermediate piece 5 which butts against the head 3 and which may rotate freely about 360 DEG around the part 2. The connection between the part 2 and the piece 5 is produced by means of a linking ring 8 which is fitted into facing recesses 6, 7. The piece 5 has two aligned journals 9 towards the outside on which the ends of a fastening loop 11 are mounted in a pivoting fashion. The integral structure of the lifting ring provides an excellent acceptance of force in the load 12 where the body of the ring is inserted. The lifting ring is particularly designed for a fixing along the horizontal axis in heavy loads intended to undergo a turning movement. <IMAGE>

Description

La présente invention concerne la prise de charges lourdes, en vue de leur manipulation, et plus particulièrement la prise latérale de telles charges.The present invention relates to the taking of heavy loads, with a view to their handling, and more particularly to the lateral taking of such loads.

On connaît des anneaux de levage qui sont calculés et réalisés en vue de la prise verticale de charges lourdes, c'est-à-dire des anneaux de levage qui se fixent selon une orientation verticale dans la pièce à soulever. Il arrive que, par commodité, certains utilisateurs emploient ces anneaux de levage connus en les fixant latéralement, c'est-à-dire selon un axe de fixation horizontal, sur des charges lourdes dont la manipulation entraîne des opérations de retournement telles par exemple que des charges constituées par certains moules. Les contraintes auxquelles l'anneau de levage est alors soumis dans ce type de manipulation étant de nature différente de celles que celui-ci est conçu pour supporter, le risque est alors grand qu'une rupture de l'anneau intervienne au cours de la manipulation en pouvant entraîner des accidents graves. De tels anneaux de levage connus sont par exemple décrits dans les documents US-A-4074519, US-A-4705422, US-A-3905633 et DE-A-3435961.Lifting rings are known which are calculated and produced for the vertical taking of heavy loads, that is to say lifting rings which are fixed in a vertical orientation in the part to be lifted. It happens that, for convenience, some users use these known lifting rings by fixing them laterally, that is to say along a horizontal fixing axis, on heavy loads whose manipulation involves turning operations such as for example that fillers formed by certain molds. The stresses to which the lifting ring is then subjected in this type of handling being of a different nature from those which the latter is designed to withstand, the risk is then great that a rupture of the ring occurs during handling by being able to cause serious accidents. Such known lifting rings are for example described in documents US-A-4074519, US-A-4705422, US-A-3905633 and DE-A-3435961.

La présente invention a pour objet de remédier à cet inconvénient des anneaux de levage conventionnels et elle propose à cet effet un anneau de levage perfectionné permettant, en toute sécurité, la prise latérale et la manipulation de charges lourdes.The object of the present invention is to remedy this drawback of conventional lifting rings and to this end it proposes an improved lifting ring allowing, in complete safety, the lateral grip and the handling of heavy loads.

Selon l'invention l'anneau de levage est constitué par un ensemble monobloc réalisé en acier de grande résistance, et il comprend un corps ayant une partie filetée se poursuivant par une partie de support de plus grand diamètre sur laquelle vient s'appuyer une pièce intermédiaire en forme de couronne, de hauteur inférieure à celle de la partie de support et conçue pour tourner sur 360° autour de cette partie de support et pour servir d'axe de pivotement, également sur 360°, pour une boucle d'accrochage.According to the invention the lifting ring is constituted by a monobloc assembly made of high strength steel, and it comprises a body having a threaded part continuing with a support part of larger diameter on which a piece comes to bear. intermediate in the form of a crown, of height less than that of the support part and designed to rotate 360 ° around this support part and to serve as a pivot axis, also 360 °, for a hooking loop.

La partie de support du corps de l'anneau d'accrochage se poursuit par une partie de tête qui sert de butée pour la pièce intermédiaire et qui présente dans sa partie centrale une partie d'actionnement en creux pour l'introduction d'une clef de serrage.The support part of the body of the hooking ring continues with a head part which serves as a stop for the intermediate piece and which has in its central part a hollow actuation part for the introduction of a key. Clamping.

La fixation par vissage de l'anneau d'accrochage dans la charge à manipuler entraîne le blocage du corps de l'anneau dans le fond du logement de la charge, la partie filetée du corps ainsi qu'une certaine longueur de la partie de support intermédiaire de celui-ci se trouvant engagées dans le logement de la charge, en ménageant toutefois le jeu de fonctionnement nécessaire entre la charge et l'extrémité des branches de la boucle d'accrochage. On comprend que, lors de la manipulation de la pièce au moyen d'un système de levage coopérant avec la boucle d'accrochage, l'anneau de levage fournit une résistance permettant, dans le cas de deux anneaux de levage alignés des deux côtés de la charge, d'atteindre en toute sécurité des charges maximales d'utilisation supérieures à 20 tonnes (dans le cas du M56).The fixing by screwing of the hooking ring in the load to be handled causes the blocking of the ring body in the bottom of the load housing, the threaded part of the body as well as a certain length of the support part intermediate thereof being engaged in the housing of the load, however providing the necessary operating clearance between the load and the end of the branches of the hooking loop. It is understood that, when handling the part by means of a lifting system cooperating with the hooking loop, the lifting ring provides a resistance allowing, in the case of two lifting rings aligned on both sides of load, safely reach maximum usage loads of more than 20 tonnes (in the case of M56).

Les deux anneaux d'accrochage étant ainsi disposés en alignement des deux côtés de la charge, pour former un axe de rotation, on comprend qu'on peut alors obtenir le retournement de la charge.The two hooking rings being thus arranged in alignment on both sides of the load, to form an axis of rotation, it is understood that one can then obtain the reversal of the load.

Pour bien faire comprendre l'invention ou en décrira ci-après, à titre d'exemple sans caractère limitatif, une forme d'exécution préférée en référence au dessin schématique annexé dans lequel :

  • la figure 1 est une vue en coupe axiale d'un exemple de réalisation d'un anneau de levage selon l'invention ; et
  • la figure 2 est une vue en élévation, à échelle réduite, montrant la posiblité de rotation de l'anneau de levage dans un plan vertical.
To make the invention clear or to describe it below, by way of example without limitation, a preferred embodiment with reference to the appended schematic drawing in which:
  • Figure 1 is an axial sectional view of an embodiment of a lifting ring according to the invention; and
  • Figure 2 is an elevational view, on a reduced scale, showing the posiblity of rotation of the lifting ring in a vertical plane.

Comme on l'a représenté à la figure 1 l'anneau de levage selon l'invention comprend un corps en acier de grande résistance présentant une partie filetée 1 de diamètre important qui se poursuit par une partie de support 2 d'un diamètre légèrement supérieur, puis par une partie de tête 3 d'un diamètre encore plus grand. Cette partie de tête 3 présente à sa partie centrale une empreinte 4 en forme de six pans creux pour l'engagement d'une clé de serrage standard (non représentée au dessin).As shown in Figure 1 the lifting ring according to the invention comprises a body of high strength steel having a threaded portion 1 of large diameter which continues with a support portion 2 of a slightly larger diameter , then by a head portion 3 of an even larger diameter. This head part 3 has at its central part an imprint 4 in the form of a hexagon socket for the engagement of a standard tightening key (not shown in the drawing).

Sur la partie de support 2 vient en appui une partie 5 en forme de couronne, de longueur inférieure à celle de la partie de support et présentant sur tout son pourtour une gorge intérieure 6 destinée, lorsque la partie 5 est en butée contre la partie de tête 3, à venir en regard d'une gorge périphérique 7 de la face extérieure de la partie de support 2. Un élément de jonction annulaire 8, engagé dans les gorges 6 et 7, solidarise en translation la partie de support 2 et la couronne 5 tout en autorisant la rotation de celle-ci sur 360°.On the support part 2 comes to bear a part 5 in the form of a crown, of length less than that of the support part and having on its entire periphery an internal groove 6 intended, when the part 5 is in abutment against the part of head 3, coming opposite a peripheral groove 7 on the outer face of the support part 2. An annular junction element 8, engaged in the grooves 6 and 7, secures in translation the support part 2 and the crown 5 while allowing it to rotate 360 °.

Vers l'extérieur la partie de support 2 présente en saillie deux axes 9 dirigés radialement et dans le prolongement l'un de l'autre, qui servent respectivement de tourillons pour des ouvertures 10 en regard des deux branches d'une boucle d'accrochage 11. Ladite boucle 11 peut donc pivoter librement sur 360° autour des tourillons 9, cette possibilité de rotation étant toutefois limitée à 180° environ, comme on le voit à la figure 2, lorsque l'anneau de levage est fixé latéralement à une charge 12.Towards the outside, the support part 2 has two projecting axes 9 projecting radially and in the extension of one another, which respectively serve as trunnions for openings 10 facing the two branches of a hooking loop. 11. Said loop 11 can therefore freely rotate 360 ° around the pins 9, this possibility of rotation being however limited to approximately 180 °, as seen in FIG. 2, when the lifting ring is fixed laterally to a load 12.

La mise en place de l'anneau de levage sur la charge 12 s'effectue par vissage, au moyen d'une clé introduite dans le creux 4 de la partie de tête 3, jusqu'à ce que la partie taraudée 1 vienne se bloquer au fond du logement 13 prévu dans la charge 12. Dans cette position une certaine partie de la longueur de la pièce de support (2) est également engagée à l'intérieur du logement 13 en fournissant une prise de force efficace.The positioning of the lifting ring on the load 12 is carried out by screwing, by means of a key inserted into the hollow 4 of the head part 3, until the threaded part 1 comes to lock at the bottom of the housing 13 provided in the load 12. In this position a certain part of the length of the support piece (2) is also engaged inside the housing 13 by providing an effective power take-off.

On comprend que, lorsque deux anneaux de levage selon l'invention ont ainsi été disposés latéralement sur la charge 12, l'un en face de l'autre pour former un axe de rotation, on peut réaliser sans difficulté un retournement de la charge grâce à la possibilité de rotation de la partie 5 sur la partie de support 2. Toutefois l'anneau de levage selon l'invention peut bien sûr être aussi utilisé pour des opérations de levage ordinaires, c'est-à-dire avec axe de vissage vertical.It is understood that, when two lifting rings according to the invention have thus been arranged laterally on the load 12, one opposite the other to form an axis of rotation, it is possible to easily turn the load through to the possibility of rotation of the part 5 on the support part 2. However the lifting ring according to the invention can of course also be used for ordinary lifting operations, that is to say with screwing axis vertical.

On donnera ci-après, à titre indicatif, un tableau des cotes de fixation et des charges maximales d'utilisation pour plusieurs modèles de l'anneau de levage selon l'invention. d (mm) 42 48 56 D (mm) 56 64 64 L (mm) 63 68 78 l (mm) 10 10 10 L + l (mm) 73 78 88 C1 (tonnes) 14 17,2 23 C2 (tonnes) 7 8,6 11,5 A table of fixing dimensions and maximum working loads for several models of the lifting ring according to the invention will be given below for information. d (mm) 42 48 56 D (mm) 56 64 64 L (mm) 63 68 78 l (mm) 10 10 10 L + l (mm) 73 78 88 C1 (tonnes) 14 17.2 23 C2 (tonnes) 7 8.6 11.5
