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 une porte très lourde équipée d'un dispositif de paumelle à montage oscillant.The present invention relates to the field of very heavy doors including access to a closed space in a hostile environment and more particularly a closed space in a nuclear power plant and has for object a very heavy door equipped with a mounting hinge device oscillating.

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 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 thrust bearing via a spherical ball, does not allow a sufficiently effective operation of the articulation 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.

Un pivot (a) supérieur traverse successivement, depuis la partie de charnière supérieure (b) fixée sur la porte (c), où il est fixé par vissage et maintenu axialement dans un manchon (j), le roulement à billes (f) et le palier de butée à billes (g) en s'étendant à son extrémité libre inférieure dans ce dernier. En outre, le palier de butée à billes est bloqué axialement dans le moyeu entre un épaulement du pivot et une pièce de base vissée dans la partie de charnière (d) fixée sur la grue, tandis que le roulement à billes est bloqué axialement entre ledit épaulement et une rondelle fermant la face externe du moyeu côté opposé à la pièce de base. La charnière inférieure comprend un roulement à billes (f) traversé par un pivot (a1) inférieur qui s'étend à sa partie inférieure dans un moyeu en venant en appui par son extrémité inférieur arrondie sur une pièce de base (m). Le roulement à billes de la charnière inférieure est bloqué axialement entre un épaulement du pivot inférieur et une rondelle fermant la face externe dudit moyeu côté opposé à la pièce de base. En outre, chaque pivot supérieur et inférieur est prévu pour pouvoir s'aligner en cas de sollicitation sur la porte tendant à désaxer lesdits pivots.Document D1 ( GB 265 388 A ), disclosing the features of the preamble of claim 1, relates to a hinge device between a door and a hoisting crane comprising an upper hinge (b, d) and a lower hinge (b, n) and whose weight of the door is supported by the upper hinge (b, d) which comprises for this purpose, in the upper hinge part (d) fixed on the crane, a hub receiving a superposition of a thrust bearing (g) ( axial loads) and a ball bearing (f) disposed above the thrust bearing (g). An upper pivot (a) passes successively, from the upper hinge portion (b) fixed on the door (c), where it is fixed by screwing and held axially in a sleeve (j), the ball bearing (f) and the thrust bearing bearing (g) extending at its lower free end therein. In addition, the thrust bearing is axially locked in the hub between a shoulder of the pivot and a base piece screwed into the hinge portion (d) attached to the crane, while the ball bearing is locked axially between said shoulder and a washer closing the outer face of the hub opposite side to the base piece. The lower hinge comprises a ball bearing (f) traversed by a lower pivot (a1) which extends at its lower part in a hub bearing by its rounded lower end on a base piece (m). The ball bearing of the lower hinge is locked axially between a shoulder of the lower pivot and a washer closing the outer face of said hub opposite to the base part. In addition, each upper and lower pivot is provided to be aligned in the event of stress on the door tending to offset said pivots.

Toutefois, ce dispositif qui est prévu pour des châssis de fenêtre ou de portes classiques n'est pas adapté pour des portes très lourdes et ne comprend pas de moyens permettant d'autoriser un défaut angulaire de coaxialité de la partie de paumelle fixe par rapport à la partie de paumelle mobile.However, this device which is intended for conventional window or door frames is not suitable for very heavy doors and does not include means making it possible to allow an angular defect of coaxiality of the fixed hinge part with respect to the mobile hinge part.

La présente invention a pour but de remédier à ces inconvénients en proposant une porte très lourde équipée d'un dispositif de paumelle à montage oscillant 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 en cas de situations exceptionnelles tel que des séismes lui permettant de répondre aux conditions de sécurité et aux normes les plus exigeantes s'appliquant aux portes très lourdes fermant des espaces clos situés en milieu hostile et plus particulièrement des espaces clos situés dans des centrales nucléaires.The object of the present invention is to overcome these drawbacks by proposing a very heavy door equipped with an oscillating mounting hinge device making it possible to prevent, in the off-axis state, any parasitic friction of the axes of the hinges during the movements of the hinges. opening or 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 a held and effective resistance in exceptional situations such as earthquakes to meet the most stringent safety conditions and standards for very heavy doors that close confined spaces in hostile environments and, in particular, confined spaces in enclosed areas. nuclear center.

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. En outre le guidage en rotation de la partie de paumelle mobile 9 par rapport à la partie de paumelle fixe 7 autour de l'axe de pivotement 11 de chaque paumelle supérieure 5 est réalisé par interposition d'une superposition d'au moins un roulement à rotule 13 destiné à supporter principalement les charges radiales et étant apte à autoriser un défaut angulaire de coaxialité de la partie de paumelle fixe 7 par rapport à la partie de paumelle mobile 9 de chaque dite paumelle supérieure 5.In accordance with the present invention, the rotational guiding of the movable hinge part 8 with respect to the fixed hinge portion 6 about the pivot axis 10 of each lower hinge 4 is achieved by interposing an axial superimposition of at least one ball bearing 12 intended to support mainly radial loads and less a ball bearing 14 intended to support mainly the axial loads, said bearing means 12 and 14 being able to allow an angular defect of coaxiality (a) of the fixed hinge portion 6 with respect to the movable hinge portion (8). ) of each said lower hinge 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. In addition, the axial spacing between said ball bearing 12 and said ball bearing 14 can be adjusted preferably by means of an adjustment spacer 14 'axially traversed by the lower pivot pin 10 and being interposed between said stopper 14 and said ball bearing 12 .
