Description

L'invention concerne un tendeur de câble de limiteur de vitesse pour ascenseur. The invention relates to a speed limiter cable tensioner for an elevator.

Les ascenseurs sont équipés d'un limiteur de vitesse comprenant notamment un câble passant sur une poulie en bas de gaine de l'ascenseur. La poulie est sollicitée vers le bas par un tendeur de câble qui est usuellement de deux types. Elevators are equipped with a speed limiter including a cable passing on a pulley at the bottom of the elevator shaft. The pulley is biased downwards by a cable tensioner which is usually of two types.

Tout d'abord le tendeur sur guide : une charge est placée à une extrémité d'un levier dont l'autre extrémité est articulée sur un support fixé au guide de l'ascenseur. La poulie est montée pivotante sur un axe situé en un point intermédiaire du levier. Ce tendeur ne peut pas être fixé sur un guide rond, et du fait du pivotement du bras, il peut en résulter un défaut d'alignement de la poulie par rapport au limiteur. First of all the tensioner on guide: a load is placed at one end of a lever whose other end is articulated on a support fixed to the guide of the elevator. The pulley is pivotally mounted on an axis located at an intermediate point of the lever. This tensioner can not be fixed on a round guide, and because of the pivoting of the arm, it may result in misalignment of the pulley relative to the limiter.

Ensuite, le tendeur fixé au sol et plat : la charge est directement appliquée sur l'axe de la poulie. La poulie est logée dans une enveloppe étroite dont la masse est fonction de la hauteur. Lorsque la masse doit être supérieure à une valeur de l'ordre de 26 kg, la hauteur de l'enveloppe entraîne une interférence avec l'étrier de cabine de l'ascenseur. Then, the tensioner fixed to the ground and flat: the load is directly applied on the axis of the pulley. The pulley is housed in a narrow envelope whose mass is a function of height. When the mass must be greater than a value of the order of 26 kg, the height of the envelope causes interference with the elevator calliper.

Un but de l'invention est de proposer un tendeur de câble qui ne présente pas les inconvénients des tendeurs de câble connus. An object of the invention is to provide a cable tensioner which does not have the disadvantages of known cable tensioners.

Un autre but de l'invention est de proposer un tendeur de câble dont la masse soit adaptable en fonction de l'installation d'ascenseur. Another object of the invention is to provide a cable tensioner whose mass is adaptable depending on the elevator installation.

L'invention a pour objet un tendeur de câble de limiteur de vitesse pour ascenseur, portant une poulie dans laquelle passe un câble du limiteur de 30 vitesse, caractérisé en ce qu'il comporte : The invention relates to a speed limiter cable tensioner for an elevator, carrying a pulley through which a speed limiter cable passes, characterized in that it comprises:

- une partie fixe, fixée au sol, en bas de la gaine d'ascenseur, et comportant un rail vertical, a fixed part, fixed on the ground, at the bottom of the elevator shaft, and comprising a vertical rail,

35 - une partie mobile, portant ladite poulie, et des galets coulissant dans ledit rail de la partie fixe. A movable part carrying said pulley and rollers sliding in said rail of the fixed part.

Avantageusement, la partie mobile est constituée d'une armature dans laquelle sont empilées des plaques constituant la masse assurant la tension du câble. De préférence, les plaques sont amovibles pour ajuster la masse du tendeur de câble. Advantageously, the mobile part consists of an armature in which are stacked plates constituting the mass ensuring the tension of the cable. Preferably, the plates are removable to adjust the mass of the cable tensioner.

Avantageusement, la partie mobile porte une rampe apte, en cas de détente ou 45 de rupture du câble, à actionner un contact de sécurité porté par la partie fixe. 40 De préférence, l'armature a une section horizontale en C. Advantageously, the mobile part carries a ramp capable, in case of expansion or breaking of the cable, to actuate a safety contact carried by the fixed part. Preferably, the armature has a horizontal section C.

Avantageusement, le rail vertical de la partie fixe a une section en C dans laquelle coulissent lesdits galets de la partie mobile. Advantageously, the vertical rail of the fixed part has a C-section in which said rollers of the movable part slide.

De préférence, l'encombrement vertical de la partie mobile est égal au diamètre nominal de la poulie augmenté de 41 mm. Preferably, the vertical bulk of the moving part is equal to the nominal diameter of the pulley increased by 41 mm.

L'invention est décrite ci-après avec référence au dessin annexé dans lequel : The invention is described below with reference to the accompanying drawing in which:

- La fig. 1 est une vue en perspective du tendeur de câble de limiteur de vitesse pour ascenseur selon un mode de réalisation de l'invention ; - La fig. 2 est une vue en perspective de l'autre côté du tendeur de câble de la fig. 1 ; - Fig. 1 is a perspective view of the elevator speed limiter cable tensioner according to one embodiment of the invention; - Fig. 2 is a perspective view of the other side of the cable tensioner of FIG. 1;

- La fig. 3 est une vue de côté du tendeur de câble en position de fonctionnement ; - Fig. 3 is a side view of the cable tensioner in the operating position;

- La fig. 4 est une vue éclatée du tendeur de câble de la fig. 1. - Fig. 4 is an exploded view of the cable tensioner of FIG. 1.

Le tendeur de câble de limiteur de vitesse pour ascenseur comporte une partie fixe 1 et une partie mobile 2. The elevator speed limiter cable tensioner has a stationary portion 1 and a movable portion 2.

La partie fixe 1 se compose essentiellement d'un socle 3 fixé au sol, en bas de la gaine d'ascenseur, et d'un rail 4 en C, vertical, dans lequel coulissent des galets de la partie mobile 2. The fixed part 1 consists essentially of a base 3 fixed to the ground, at the bottom of the elevator shaft, and a vertical C-shaped rail 4 in which rollers of the movable part 2 slide.

30 La partie mobile 2 comprend essentiellement une armature 5 à section horizontale en C dans laquelle sont empilées des plaques 6 de métal lourd constituant la masse réglable du tendeur de câble. A l'extérieur de la grande face 10 de l'armature 5 est disposée la poulie 7 dans la gorge de laquelle passe le câble 8. L'axe 9 de la poulie 7 est placé pratiquement au centre de la grande 35 face 10 de l'armature. La grande face 10 de l'armature est rectangulaire, le diamètre de la poulie étant pratiquement égal à la largeur de la grande face 10 de l'armature 5, et légèrement inférieur à la hauteur de la grande face 10. Ainsi, en hauteur et en largeur, l'encombrement du tendeur de câble est à peine supérieur à celui de la poulie 7. 40 L'armature 5 porte sur l'une de ses petites faces 11 des galets qui coulissent dans le rail 4 en C de la partie fixe 1. 25 A sa partie inférieure, la petite face 11 de l'armature 5 de la partie mobile 2 porte une rampe 12, apte à actionner un contact de sécurité 13 porté par la partie fixe 1. The movable part 2 essentially comprises a frame 5 of horizontal section C in which are stacked plates 6 of heavy metal constituting the adjustable mass of the cable tensioner. Outside the large face 10 of the frame 5 is disposed the pulley 7 in the groove of which the cable 8 passes. The axis 9 of the pulley 7 is placed substantially in the center of the large face 10 of the frame. The large face 10 of the frame is rectangular, the diameter of the pulley being substantially equal to the width of the large face 10 of the frame 5, and slightly less than the height of the large face 10. Thus, in height and in width, the size of the cable tensioner is barely greater than that of the pulley 7. The armature 5 carries on one of its small faces 11 rollers which slide in the rail 4 in C of the fixed part 1. At its lower part, the small face 11 of the frame 5 of the mobile part 2 carries a ramp 12, able to actuate a safety contact 13 carried by the fixed part 1.

Le poids de la partie mobile 2 du tendeur de câble de limiteur de vitesse de l'ascenseur tend le câble 8. Lorsque le câble 8 est détendu ou rompu, c'est-à-dire lorsque le limiteur de vitesse et le parachute sont dans l'incapacité de fonctionner, la partie mobile 2 descend et la rampe 12 actionne le contact de sécurité 13 qui coupe la chaîne de sécurité de l'ascenseur et interdit son fonctionnement. The weight of the moving part 2 of the speed limiter cable tensioner of the elevator stretches the cable 8. When the cable 8 is relaxed or broken, that is to say when the speed limiter and the parachute are in the inability to operate, the moving part 2 goes down and the ramp 12 actuates the safety contact 13 which cuts the safety chain of the elevator and prohibits its operation.

Le tendeur de câble selon l'invention assure la mise sous tension du câble 8 du limiteur de vitesse d'un ascenseur en cas de survitesse de la cabine d'ascenseur. Le tendeur de câble est très compact. La masse assurant la tension du câble 8 n'est pas plus encombrante verticalement que le diamètre nominal de la poulie 7 augmenté de 41 mm, ce qui permet la disposition du tendeur de câble dans le fond de gaine d'ascenseur, sans risque d'interférence avec l'étrier de cabine 14. The cable tensioner according to the invention ensures the tensioning of the cable 8 of the speed limiter of an elevator in case of overspeed of the elevator car. The cable tensioner is very compact. The mass ensuring the tension of the cable 8 is not more bulky vertically than the nominal diameter of the pulley 7 increased by 41 mm, which allows the provision of the cable tensioner in the bottom of the elevator shaft, without risk of interference with cabin stirrup 14.

La disposition de plaques amovibles 6 dans l'armature 5 permet d'ajuster la masse du tendeur de câble, et donc l'effort sur le câble du limiteur de vitesse, en fonction de l'installation d'ascenseur. The provision of removable plates 6 in the armature 5 makes it possible to adjust the mass of the cable tensioner, and therefore the force on the cable of the speed limiter, according to the elevator installation.

A titre d'exemple, le tendeur de câble de limiteur de vitesse est conçu pour une poulie de diamètre égal à 200 mm ou à 300 mm. For example, the speed limiter cable tensioner is designed for a pulley with a diameter of 200 mm or 300 mm.

Le mode de réalisation du tendeur de câble de limiteur de vitesse a été décrit à titre illustratif et non limitatif.30 The embodiment of the speed limiter cable tensioner has been described by way of illustration and not limitation.
