Description

La présente invention concerne le domaine des portes très lourdes permettant notamment l'accès à un espace clos dans un milieu hostile et plus particulièrement un espace clos dans une centrale nucléaire et a pour objet un dispositif de paumelle à montage oscillant destiné à équiper de telles portes très lourdes. Elle a également pour objet une telle porte très lourde équipée dudit dispositif de paumelle.The present invention relates to the field of very heavy doors including access to a confined space in a hostile environment and more particularly a closed space in a nuclear power plant and relates to an oscillating mounting hinge device for equipping such doors very heavy. It also relates to such a very heavy door equipped with said hinge device.

On sait qu'une paumelle classique de porte comprenant un battant pivotant autour d'un axe vertical est constituée, d'une part, par deux parties de paumelle, dont l'une, fixe, est montée sur le dormant et l'autre, mobile, est montée sur ledit battant pivotant, et d'autre part par un axe de pivotement, généralement solidaire du dormant ou, le cas échéant, du battant, permettant le guidage en rotation par glissement, autour dudit axe de pivotement, de l'une desdites parties de paumelle par rapport à l'autre.It is known that a conventional door hinge comprising a flap pivoting about a vertical axis is formed, on the one hand, by two parts of hinge, one of which, fixed, is mounted on the frame and the other, mobile, is mounted on said pivoting flap, and secondly by a pivot axis, generally integral with the frame or, where appropriate, the flapper, for guiding in rotation by sliding, about said pivot axis, the one of said hinge parts with respect to the other.

Les paumelles existantes équipent toutes sortes de portes de poids différents, mais celles qui équipent des portes très lourdes, pesant plusieurs tonnes, doivent supporter axialement des charges importantes, dont les exigences et les normes actuelles en matière de sécurité sont très élevées.Existing hinges equip all kinds of doors of different weights, but those that equip very heavy doors, weighing several tons, must support axially heavy loads, whose requirements and current standards of security are very high.

Ceci est particulièrement le cas des portes très lourdes qui sont installées, à l'aide de grues, dans des environnements hostiles tels que des centrales nucléaires et notamment dans le bâtiment desdites centrales qui contient le réacteur nucléaire.This is particularly the case for very heavy doors which are installed, using cranes, in hostile environments such as nuclear power plants and in particular in the building of said power plants which contains the nuclear reactor.

On connaît déjà des systèmes de paumelle équipant de telles portes très lourdes qui comprennent généralement une paumelle inférieure destinée à supporter au moins l'essentiel de la charge du battant de la porte et une paumelle supérieure destinée principalement à former un point de maintien anti-basculement et de guidage axial du battant de ladite porte.Hinge systems fitted to such very heavy doors are known which generally comprise a lower hinge intended to support at least most of the load of the door leaf and an upper hinge intended primarily to form an anti-tilt holding point. and axial guiding of the wing of said door.

Dans un système de paumelle de ce type, la paumelle inférieure et la paumelle supérieure comprennent chacune un axe de pivotement respectivement inférieur et supérieur, permettant le guidage en rotation de la partie de paumelle mobile respectivement inférieure et supérieure par rapport à la partie de paumelle fixe respectivement inférieure et supérieure, autour dudit axe de pivotement, ce par interposition de moyens de roulement.In a hinge system of this type, the lower hinge and the upper hinge each comprise a respectively lower and upper pivoting axis, allowing the rotational guiding of the movable hinge portion respectively lower and upper with respect to the fixed hinge part. respectively lower and upper, about said pivot axis, this by interposition of rolling means.

Par ailleurs, le pivotement du battant de la porte pour sa mise en ouverture ou en fermeture est réalisé par un système mécanique à manivelle ou par une motorisation, dont le moteur est généralement fixé sur le dormant et entraîne un arbre de rotation solidaire du battant et notamment de la partie de paumelle mobile de la paumelle inférieure.Furthermore, the pivoting of the door leaf for its opening or closing is achieved by a mechanical crank system or by a motor, whose motor is generally fixed on the frame and drives a rotation shaft integral with the leaf and in particular the movable hinge portion of the lower hinge.

Toutefois, il a été constaté que lors de l'ouverture d'une telle porte très lourde, des flexions se produisent fréquemment au niveau du dormant entraînant un mouvement de désaxage des deux paumelles respectivement supérieure et inférieure qui génère des frottements importants au niveau de l'un et/ou l'autre des axes desdites paumelles, ce qui a pour effet de créer un grippage entre l'axe considéré et la paumelle correspondante et un effort de pivotement accru lors des mouvements de fermeture ou d'ouverture du battant pivotant de ladite porte.However, it has been found that during the opening of such a very heavy door, flexures frequently occur at the frame resulting in a misalignment movement of the two upper and lower hinges respectively, which generates significant friction at the level of the frame. one and / or the other of the axes of said hinges, which has the effect of creating a seizure between the axis in question and the corresponding hinge and an increased pivoting force during the closing or opening movements of the pivoting flap of said door.

Or, si l'ouverture ou la fermeture des battants de telles portes très lourdes peuvent néanmoins être effectuées, même à l'état désaxé, grâce à l'utilisation de motorisations de forte puissance pour lutter contre les frottements générés par ledit état, cela va à l'encontre des exigences économiques actuelles en matière de réduction des coûts de fabrication de telles portes et de baisse de la consommation desdites motorisations, qui ne peuvent être respectées que par l'utilisation de motorisations de puissance limitée.However, if the opening or closing of the doors of such very heavy doors can nevertheless be made, even in the off-axis state, thanks to the use of high power engines to fight against the friction generated by said state, this will against the current economic requirements for reducing the manufacturing costs of such doors and reducing the consumption of said engines, which can only be met by the use of limited power engines.

Le document FR 829 875 a pour objet un dispositif d'articulation du vantail d'une porte au moyen d'un montant pivot constitué par un tube métallique engagé à son extrémité inférieure sur un pivot formant crapaudine scellée dans le sol et à son extrémité supérieure sur un pivot, lesdites extrémités étant obturées respectivement par une cuvette supérieure et une cuvette inférieure, tandis qu'une bille sphérique est interposée entre le fond de cuvette inférieure et la face supérieure du pivot inférieure.The document FR 829 875 relates to a device for hinging the leaf of a door by means of a pivot amount consisting of a metal tube engaged at its lower end on a pivot forming a crapaudine sealed in the ground and at its upper end on a pivot, said ends being closed respectively by an upper bowl and a lower bowl, while a spherical ball is interposed between the lower bottom bottom and the upper face of the lower pivot.

Toutefois, ce type de dispositif qui comporte un tube métallique, formant charnière, nécessitant un scellement de son extrémité inférieure dans le sol au moyen d'une crapaudine par l'intermédiaire notamment d'une bille sphérique, ne permet pas un fonctionnement suffisamment efficace de l'articulation pour une application sur une porte très lourde, notamment d'une porte utilisée dans une centrale nucléaire. En outre, les portes très lourdes utilisées dans le domaine du nucléaire doivent pouvoir tenir ou résister à un séisme, ce que ne permet pas un dispositif d'articulation tel que celui décrit dans le document précité, équipant une telle porte. En effet, dans ce type de dispositif, lors d'un séisme engendrant des mouvements combinés de la porte dans plusieurs directions, la bille sort de son logement affectant d'autant la tenue et la résistance de la porte durant ces mouvements brusques.However, this type of device which comprises a metal tube, forming a hinge, requiring a seal of its lower end in the ground by means of a crapaudine through including a spherical ball, does not allow a sufficiently effective operation of the joint for application on a very heavy door, including a door used in a nuclear power plant. In addition, very heavy doors used in the nuclear field must be able to withstand or withstand an earthquake, which is not possible articulation such as that described in the aforementioned document, equipping such a door. Indeed, in this type of device, during an earthquake generating combined movements of the door in several directions, the ball out of its housing affecting all the strength and strength of the door during these sudden movements.

La présente invention a pour but de remédier à ces inconvénients en proposant un dispositif de paumelle à montage oscillant pour porte très lourde permettant d'empêcher, à l'état désaxé, tous frottements parasites des axes des paumelles lors des mouvements d'ouverture ou de fermeture du battant de ladite porte, que la porte soit équipée d'une motorisation, notamment de puissance limitée, ou d'un système mécanique d'ouverture par exemple grâce à une manivelle, tout en conférant à la porte une tenu et une résistance efficace, notamment en cas de séisme.The object of the present invention is to overcome these drawbacks by proposing an oscillating mounting hinge device for a very heavy door which makes it possible to prevent, in the off-axis state, any parasitic friction of the axes of the hinges during opening or closing movements. closing the door of said door, the door is equipped with a motor, including limited power, or a mechanical opening system for example through a crank, while giving the door an effective resistance and resistance , especially in case of earthquake.

A cet effet, le dispositif de paumelle à montage oscillant destiné à équiper une porte très lourde constituée par au moins un battant ou vantail monté pivotant sur un dormant, comprenant au moins une paumelle inférieure destinée notamment à supporter au moins l'essentiel de la charge du battant de ladite porte et au moins une paumelle supérieure destinée notamment à former un point de maintien anti-basculement et de guidage axial dudit battant, chaque dite paumelle inférieure, respectivement supérieure, d'une part, étant constituée par une partie de paumelle fixe, respectivement, solidaire du dormant et par une partie de paumelle mobile, respectivement, solidaire du battant et, d'autre part, comprenant un axe de pivotement solidaire dudit dormant ou, le cas échéant, du battant, permettant le guidage en rotation de la partie de paumelle mobile par rapport à la partie de paumelle fixe autour dudit axe de pivotement, ce par interposition de moyens de roulement et se caractérise essentiellement en ce que :

  • le guidage en rotation de la partie de paumelle mobile par rapport à la partie de paumelle fixe autour de l'axe de pivotement de chaque paumelle inférieure est réalisé par interposition d'une superposition axiale d'au moins un roulement à rotule destiné à supporter principalement des charges radiales et d'au moins une butée à rotule destinée à supporter principalement les charges axiales, lesdits moyens de roulements étant aptes à autoriser un défaut angulaire de coaxialité (a) de la partie de paumelle fixe par rapport à la partie de paumelle mobile de chaque dite paumelle inférieure, et
  • le guidage en rotation de la partie de paumelle mobile par rapport à la partie de paumelle fixe autour de l'axe de pivotement de chaque paumelle supérieure est réalisé par interposition d'une superposition d'au moins un roulement à rotule destiné à supporter principalement les charges radiales et étant apte à autoriser un défaut angulaire de coaxialité de la partie de paumelle fixe par rapport à la partie de paumelle mobile de chaque dite paumelle supérieure.

  • the rotational guiding of the movable hinge portion relative to the fixed hinge portion about the pivot axis of each lower hinge is achieved by interposition of an axial superposition of at least one ball bearing intended to support mainly radial loads and at least one spherical abutment intended to support mainly the axial loads, said bearing means being able to allow an angular defect of coaxiality (a) of the fixed hinge portion relative to the movable hinge portion of each said lower hinge, and

Conformément à la présente invention, le guidage en rotation de la partie de paumelle mobile 8 par rapport à la partie de paumelle fixe 6 autour de l'axe de pivotement 10 de chaque paumelle inférieure 4 est réalisé par interposition d'une superposition axiale d'au moins un roulement à rotule 12 destiné à supporter principalement des charges radiales et d'au moins une butée à rotule 14 destinée à supporter principalement les charges axiales, lesdits moyens de roulements 12 et 14 étant aptes à autoriser un défaut angulaire de coaxialité (a) de la partie de paumelle fixe 6 par rapport à la partie de paumelle mobile (8) de chaque dite paumelle inférieure 4.

La butée à rotule 14 est avantageusement associée, de façon conjuguée, avec ledit roulement à rotule 12 d'une telle manière que ledit point d'application A corresponde sensiblement au centre de pivotement dudit roulement à rotule 12. En outre l'écartement axial entre ledit roulement à rotule 12 et ladite butée à rotule 14 peut être ajusté de préférence au moyen d'une entretoise d'ajustement 14' traversée axialement par l'axe de pivotement inférieur 10 et étant intercalée entre ladite butée 14 et ledit roulement à rotule 12.If we now refer to the figure 2 it can be seen that each lower hinge 4 may preferably comprise a ball bearing 12 and a ball bearing 14, whose point of application A of the resultant of the contact actions of the rolling elements 15 of said ball bearing 14 is eccentric in relation to its median plane. The ball stop 14 is advantageously associated, in conjunction with said ball bearing 12, in such a way that said application point A corresponds substantially to the center of pivoting of said ball bearing 12.
