Abstract

The present invention relates to a device 10 supporting the free end 3 of a substantially horizontal bar 2 which is built in at its other end, and allowing a substantially horizontal deflection of the free end 3 of this bar, characterised in that it is composed of one or more sets of three beams 12, 13, 14 articulated to each other, two beams 12, 13 free solely to rotate, each one about a fixed articulation pin D, E located at one of their ends, and a third beam 14 connected by one of its ends to the free end of the bar 3, the other two ends of the two beams which are free solely to rotate being connected one substantially to the centre of the third beam 14 by means of an articulation pin A, and the other to the other end of this third beam by means of another articulation pin B. Application to supporting output tubes of shielded electrical distribution stations.

Description

La présente invention concerne un dispositif supportant l'extré- mité libre d'une barre sensiblement horizontale encastrée à son autre extrémité, et permettant un débattement sensiblement horizontal de l'extrémité libre de cette barre. The present invention relates to a device supporting the free end of a substantially horizontal bar recessed at its other end, and allowing a substantially horizontal clearance of the free end of this bar.

On connaît des dispositifs de ce type constitués d'un chariot mobile sur lequel prend appui l'extrémité libre de la barre. Ces dispositifs sont notamment utilisés pour supporter l'extrémité libre des tubes de sortie horizontaux d'un poste blindé de distribution électrique. There are known devices of this type consisting of a movable carriage on which bears the free end of the bar. These devices are used in particular to support the free end of the horizontal output tubes of a shielded electrical distribution station.

Quand un poste blindé est installé dans des régions chaudes, le tube, qui peut atteindre une longueur d'environ 10 mètres, est soumis à une dilatation importante et le support de son extrémité libre doit donc se déplacer librement sur une longueur qui peut atteindre 40 cm. Les roues des chariots des dispositifs connus sont guidées sur des rails en plein air, et comme ces régions sont souvent des régions fortement sablonneuses, les roues sont rapidement ensablées. Elles peuvent ensuite se bloquer et nuire à un bon débattement de l'extrémité libre du tube et même provoquer une rupture de celui-ci. When a shielded substation is installed in hot areas, the tube, which can reach a length of about 10 meters, is subject to significant expansion and the support of its free end must therefore move freely over a length of up to 40 meters. cm. The wheels of the trolleys of known devices are guided on rails in the open air, and as these areas are often highly sandy regions, the wheels are quickly silted. They can then block and interfere with a good deflection of the free end of the tube and even cause a rupture thereof.

La présente invention a pour but de supprimer tout utilisation de roulettes en remplaçant le chariot mobile par un dispositif à trois poutres comportant uniquement des articulations simples. The present invention aims to eliminate any use of wheels by replacing the carriage by a three-beam device with only simple joints.

Le dispositif de la présente invention est caractérisé en ce qu'il se compose d'un ou plusieurs ensembles de trois poutres articulées entre elles, deux poutres libres selon uniquement une rotation chacune autour d'un axe d'articulation fixe situé à l'une de leur extrémité, et une troisième poutre reliée par une de ses extrémités à l'extrémité libre de la barre, les deux autres extrémités des deux poutres libres uniquement en rotation, étant reliées l'une sensiblement au centre de la troisième poutre par l'intermédiaire d'un axe d'articulation, et l'autre à l'autre extrémité de cette troisième poutre par l'intermédiaire d'un autre axe d'articulation. The device of the present invention is characterized in that it consists of one or more sets of three beams hinged together, two free beams only one rotation each about a fixed axis of articulation located at one their end, and a third beam connected by one of its ends to the free end of the bar, the two other ends of the two beams only in rotation, being connected one substantially to the center of the third beam by the intermediate of a hinge axis, and the other at the other end of the third beam through another axis of articulation.

De préférence les deux axes d'articulations des deux poutres libres uniquement en rotation sont sur une même verticale. Preferably the two axes of articulation of the two free beams only in rotation are on the same vertical.

I1 est décrit ci-après, à titre d'exemple et en référence à l'unique dessin annexé, un ensemble du dispositif selon l'invention, utilisé pour supporter un tube horizontal d'un poste blindé. I1 is described below, by way of example and with reference to the single accompanying drawing, an assembly of the device according to the invention, used to support a horizontal tube of a shielded station.

D'un poste blindé sortent de multiples tubes qui prennent toutes les directions possibles et notamment une direction horizontale comme le tube 2 représenté dans cette figure. A shielded post out multiple tubes that take all possible directions including a horizontal direction as the tube 2 shown in this figure.

Ce tube comporte une extrémité libre 3 sur laquelle est montée une borne de sortie 5, ce tube 2 et cette borne 5 étant traversés par un conducteur électrique 6 quelconque. This tube comprises a free end 3 on which is mounted an output terminal 5, this tube 2 and this terminal 5 being traversed by any electrical conductor 6.

Le dispositif de l'invention est installé entre une chape 4 fixée à l'extrémité libre 3 du tube 2, et un socle 11. The device of the invention is installed between a yoke 4 fixed to the free end 3 of the tube 2, and a base 11.

Ce dispositif est constitué de trois poutres 12, 13, 14. This device consists of three beams 12, 13, 14.

La poutre 12 est articulée en rotation sur le socle 11 par l'intermédiaire d'un axe D et environ au milieu de la poutre 14 par l'intermédiaire d'un axe A. The beam 12 is articulated in rotation on the base 11 via an axis D and approximately in the middle of the beam 14 via an axis A.

La poutre 13 est articulée en rotation sur le socle 11 par l'intermédiaire d'un axe E et à une extrémité de la poutre 14 par l'intermédiaire d'un axe B. Les axes D et E sont sensiblement sur une même verticale du socle 11. The beam 13 is articulated in rotation on the base 11 via an axis E and at one end of the beam 14 via an axis B. The axes D and E are substantially on the same vertical of the base 11.

La poutre 14 est donc articulée en trois points, au niveau de l'axe
A de la poutre 12, au niveau de l'axe B de la poutre 13 et enfin au niveau de la chape 4 par un axe C.The beam 14 is articulated at three points, at the axis
A of the beam 12, at the axis B of the beam 13 and finally at the yoke 4 by a C axis.

Lors d'un déplacement horizontal de l'extrémité libre 3 vers la gauche, la figure montre que le point A se déplace en A', le point B en B', et le point C en C', le point C' étant sensiblement sur la même horizontale que le point C. During a horizontal displacement of the free end 3 to the left, the figure shows that the point A moves at A ', the point B at B', and the point C at C ', the point C' being substantially on the same horizontal as the point C.

En réalité, le décalage en hauteur peut souvent être accepté jusqu'à 10% du décalage horizontal. Pour un tube de 10 mètres de long, le décalage horizontal est au maximum de 40 centimètres et le décalage vertical acceptable est donc d'environ 4 centimètres.  In reality, the height offset can often be accepted up to 10% of the horizontal offset. For a tube 10 meters long, the horizontal offset is at most 40 centimeters and the acceptable vertical offset is about 4 centimeters.
