Definitions
- the invention relates to a device for controlling at least one inductive sensor of a cable lifeline, said device comprising first sensor support means, integral with a roller balance associated with a pylon of the line, and second means able to vary the air gap between the cable and the sensor.
- the functional test of the inductive sensors of a cable-type lifeline of the carrier-tractor type generally requires disassembly of the sensors, or a local monitoring and test intervention on the various towers of the ski lift.
- the implementation of this control operation is long, complicated and takes place once before the installation is put back into operation.
- any misalignment or detachment of the cable at the passage of the pylon carrying this defective sensor will not be detected quickly enough. This then results in a risk of derailment and failure that calls into question the safety of the installation.
- the object of the invention is to remedy all of the aforementioned drawbacks and to provide a device for controlling an inductive sensor improving the existing operating tests, while being easy to implement and possibly performed at any time and without disassembling the sensor.
- Such automatic actuation by a specific test carriage and such means of support and actuation avoid the installation of a test sleeve on the cable, and require no human intervention. This results in a fully automatic control via the test carriage passing through the sensors to be controlled. Such a control device is very easy to use.
- the fixed part of the first support means comprises a bent plate having a first side fixed on the balance and parallel to the rollers, and a second side perpendicular to the first side and provided at its end with a pivot axis, articulating the moving part of the support means.
- Resilient return means bias the movable portion of the detection position of the absence of the cable to the position of detection of the presence of the cable.
- control device 10 is intended to verify the proper functioning of an inductive sensor 11, preferably a pair of sensors 11 as shown in FIG. figure 4 , sure a rope lift line 12 of the tractor-carrier type.
- an inductive sensor 11 preferably a pair of sensors 11 as shown in FIG. figure 4 , sure a rope lift line 12 of the tractor-carrier type.
- the description below refers to a single sensor 11, but it can be applied to any number of sensors 11.
- the control of the operation of the sensor 11 consists of making it take two characteristic positions, namely a first position of detection of the presence of the cable 12, close to the sensor 11 ( figures 1 and 5 ), and a second detection position of the absence of the cable 12, away from the cable 12 ( figures 2 and 6 ).
- the sensor 11 is connected to a management system, taking into account these two characteristic positions and to test the position of the sensor 11, to ensure its good reaction in case of problems.
- the control device 10 cooperates with a test trolley 13, that is to say any vehicle of the gondola type, chairlift, etc., specifically configured to carry out the control of a sensor 11 positioned at a pylon from the lift line.
- the test carriage 13, intended to serve only to control the sensors 11 ( figure 2 ) is interposed between conventional carriages 14 ( figure 1 ), so as to carry out the tests during the operation of the lifeline and the running of the cable 12.
- On the Figures 1 and 2 only the upper part, respectively, of a conventional carriage 14 and a test carriage 13 are shown, with a clamp 15 surrounding the cable 12 and flowing along the mechanical lift line.
- control device 10 is arranged on a support rocker 16 comprising, for example, two rollers 17, mounted to rotate - free at opposite ends of the rocker arm 16 ( figure 4 ), which is connected to the supporting structure of a pylon (not shown for reasons of clarity).
- first support means comprising a first fixed part in the form of a bent plate 18 ( Figures 1, 2 and 4 ), with a first flank 18a integral with the balance 16 corresponding and parallel to the rollers 17, and a second flank 18b, perpendicular to the first flank 18a and projecting between two adjacent rollers 17 of the balance ( figure 4 ).
- a pivot axis 19 is arranged at the end of the sidewall 18b of the bent plate 18 fixed support means ( Figures 1 and 2 ).
- the first support means of the sensor 11 also comprise a second movable part, pivotally mounted relative to the bent plate 18 fixed around the pivot axis 19.
- the movable part is, for example, in the form of a cam 20 bent, having a portion 21 projecting, extending substantially perpendicular to the rollers 17 on the side of the carriages traveling along the lift ( Figures 1 and 2 ).
- the protruding portion 21 of the movable cam 20 of the support means comprises a rounded edge 22, acting as a contact surface for actuating the movable part, namely the cam 20 of the first support means of the sensor 11 as described below.
- the support means of the sensor 11 also comprise a U-shaped holding member 23 integral with the movable cam 20 and also pivotally mounted relative to the fixed bent plate 18 about the pivot axis 19.
- the U-shaped holding member 23 comprises a first horizontal branch, abutting against the bent plate 18, fixing support means, in the first position of the sensor 11 ( figure 1 ), and a second horizontal leg, encircling the sensor 11, or the pair of sensors 11 ( Figures 3 and 4 ).
- the holding member 23 of the sensor 11 allows in particular to raise the sensor 11 and place it near the cable 12, in the first position of detection of the presence of the cable ( figure 1 ).
- the sensor 11 is in its first position of detecting the presence of the cable 12.
- the holding member 23 is vertical and the sensor 11 is aligned with the rollers 17 of the rocker 16.
- the projecting portion 21 of the cam Mobile is substantially perpendicular to the beam 16 and the sensor 11 is close to the cable 12, just below it, so as to leave a slight gap. Such a position then allows a conventional carriage 14 to pass next to the corresponding pylon, without triggering the control or the test of the sensor 11.
- the test carriage 13 is equipped with an actuating ramp 24 constituting the second means of the control device 10 according to the invention;
- the ramp 24 is arranged at the upper part of the arm of the test carriage 13 and is intended to cooperate with the rounded edge 22 of the projecting portion 21 of the movable cam 20 of the first support means of the sensor 11.
- the actuating ramp 24 is, for example, in the form of a fixed disc, integral with the test carriage 13 and comprising a lower ramp 24a, cooperating with the rounded edge 22 of the projecting portion 21 of the movable cam 20. support means.
- the lower ramp 24a comes into contact with the projecting portion 21, sliding along the rounded edge 22, thus causing the pivoting of the movable cam 20 about the pivot axis 19, which then causes the rotation of the body 23, which then moves the sensor 11 away from the cable 12, thereby forming a first angle of inclination with respect to the vertical ( figure 2 ).
- the sensor 11 is then in a position limit, corresponding to the second detection position of the absence of the cable 12, in which it is away from the cable 12 opposite the actuating ramp 24a.
- the device 10 comprises a return spring 26 ( Figures 1 and 2 ), playing the role of resilient return means, to automatically move the sensor 11 from its second detection position of the absence of the cable 12 ( figure 2 ) to its first position of detection of the presence of the cable 12 ( figure 1 ), after the passage of the test carriage 13.
- test carriage 13 also comprises an upper ramp 25b intended to cooperate with the mobile part of the support means of a sensor 11 of a control device 10 according to the invention integral with a compression beam 25 , as described below for the variant embodiment described in Figures 5 and 6 .
- the control device 10 differs from the control device represented on the Figures 1 and 2 by the shape of the support means of the sensor 11 and by the actuation of the movable part of the first support means.
- the variant embodiment of the device 10 is associated with a compression rocker 25, that is to say with a rocker arm placed above the cable 12 (not shown in FIGS. Figures 5 and 6 for reasons of clarity) running along the lift line.
- the upper part of the clamp 15 cooperates with the grooves of the rollers 17 of the balance 25 to allow the cable 12 to run.
- the device 10 comprises the fixed bent plate 18 and the movable cam 20, hinged about the pivot axis 19 relative to the bent plate 18 fixed.
- the test carriage 13, more particularly the upper actuating ramp 24b of the test carriage 13 cooperates with the rounded edge 22 of the projecting portion 21 of the movable cam 20, in order to actuate the movable part of the support means and incline the sensor 11, to move it from its detection position the presence of the cable ( figure 5 ) to its position of detection of the absence of the cable ( figure 6 ), as previously described.
- the holding member 23 of the sensor 11 has a different form of the previous embodiment.
- the holding member 23 of the sensor 11 has a substantially bent dissymetrical section and protrudes away from the rollers 17 of the compression balance 25, so that the sensor 11 is in the vicinity and opposite the clamp 15, between two rollers 17 adjacent and in a plane parallel to the rollers 17 ( figure 5 ).
- the sensor 11 is positioned parallel to the rollers 17 on the side of the clamp 15 away from the cable 12, with a predetermined distance, in the first position of detection of the presence of the cable 12.
- the upper actuating ramp 24b of the test carriage 13 has caused the pivoting of the movable cam 20 around the pivot axis 19, followed by the inclination of the holding member 23 and therefore the sensor 11, in the second detection position of the absence of the cable 12.
- control device 10 of the sensor 11 associated with a compression rocker 25 is therefore identical to the operation of the device 10 associated with the support rocker 16, as previously described.
- the control device 10 also comprises the return spring 26, to accompany the return of the sensor 11 to the detection position of the presence of the cable 12, as shown in FIG. figure 5 .
- such a control device 10 with support means comprising a mobile part, actuated by a ramp 24 integral with a test carriage 13, in order to to pass the sensor from a position of detection of the presence of the cable 12 to a position of detection of the absence of the cable 12, is therefore very simple to use, without intervention of the operator and without any temporary installation.
- the automatic position change and the simple inclination of the sensor 11 relative to the cable 12, during the passage of the test carriage 13 at the pylon associated with the control device 10, is sufficient to perform the tests to control whether the sensor 11 operates well, so that it is reactive in case of any problems, of the derailment type or others, appearing at the level of the cable 12.
- Such a test thus makes it possible to verify the operational safety of the ropeway lift installation without any dismantling of the sensors 11 on all the towers. It is thus possible to quickly test the line by doing an automatic test, by scrolling the test carriage along the line of the ski lift. In the event of a defect of a sensor 11, the control device 10 of the pylon supporting it is immediately identified, thus allowing a rapid intervention for its replacement.
- the invention is not limited to the various embodiments described above.
- the shape of the first support means and second actuating means of the control device 10 may be different, as long as it allows a control of the sensor 11 effective, simple and without intervention of an operator.
- the control device 10 can be used with a support beam ( Figures 1 and 2 ), with a compression pendulum ( Figures 5 and 6 ) or at the same time with a mixed balance of support and compression.
- the actuating ramp 24 of the test carriage 13 comprises in all cases a lower ramp 24a and an upper ramp 24b, preferably identical and symmetrical.
- the invention applies in particular to any type of ropeway lift-tractor. It is clear that the test of the sensors 11 for a steel cable 12, used for a mechanical lift of the chairlift or gondola type, can be applied to a rail when the installation consists of a funicular.

Abstract
Description
L'invention est relative à un dispositif de contrôle d'au moins un capteur inductif d'une ligne de remontée mécanique à câble, ledit dispositif comportant des premiers moyens de support du capteur, solidaires d'un balancier à galets associé à un pylône de la ligne, et des deuxièmes moyens aptes à faire varier l'entrefer entre le câble et le capteur.The invention relates to a device for controlling at least one inductive sensor of a cable lifeline, said device comprising first sensor support means, integral with a roller balance associated with a pylon of the line, and second means able to vary the air gap between the cable and the sensor.
Le test de fonctionnement des capteurs inductifs d'une ligne de remontée mécanique à câble du type porteur-tracteur nécessite généralement un démontage des capteurs, ou une intervention locale de surveillance et de test sur les différents pylônes de la remontée mécanique. La mise en oeuvre de cette opération de contrôle est longue, compliquée et s'effectue une seule fois avant la remise en exploitation de l'installation. En cas de défaut d'un capteur au cours de la période d'exploitation, un éventuel désalignement ou décollement du câble au passage du pylône portant ce capteur défectueux, ne sera pas détecté assez rapidement. Il en résulte alors un risque de déraillement et de panne qui remet en cause la sécurité de l'installation.The functional test of the inductive sensors of a cable-type lifeline of the carrier-tractor type generally requires disassembly of the sensors, or a local monitoring and test intervention on the various towers of the ski lift. The implementation of this control operation is long, complicated and takes place once before the installation is put back into operation. In the event of a sensor fault during the operating period, any misalignment or detachment of the cable at the passage of the pylon carrying this defective sensor, will not be detected quickly enough. This then results in a risk of derailment and failure that calls into question the safety of the installation.
Une solution pour le contrôle et le test de fonctionnement des capteurs inductifs a déjà été proposée notamment par les brevets
Cependant, l'installation d'un tel manchon est relativement compliquée, le manchon étant constitué de deux parties à assembler autour du câble, et un tel dispositif de contrôle est difficile à mettre en oeuvre, car il nécessite notamment l'intervention d'un opérateur pour l'installation et la vérification de l'entrefer entre le câble et le manchon.However, the installation of such a sleeve is relatively complicated, the sleeve consisting of two parts to be assembled around the cable, and such a control device is difficult to implement, because it requires in particular the intervention of a operator for the installation and verification of the air gap between the cable and the sleeve.
L'invention a pour but de remédier à l'ensemble des inconvénients précités et a pour objet la réalisation d'un dispositif de contrôle d'un capteur inductif améliorant les tests existants de fonctionnement, tout en étant facile à mettre en oeuvre et pouvant être réalisé à tout moment et sans démontage du capteur.The object of the invention is to remedy all of the aforementioned drawbacks and to provide a device for controlling an inductive sensor improving the existing operating tests, while being easy to implement and possibly performed at any time and without disassembling the sensor.
L'objet de l'invention est caractérisé en ce que :
- les deuxièmes moyens pour faire varier l'entrefer comportent une rampe d'actionnement agencée sur un chariot de test destiné à coopérer avec le dispositif de contrôle pour faire passer le capteur d'une première position de détection de la présence du câble vers une seconde position de détection de l'absence du câble,
- les premiers moyens de support du capteur comportent une partie fixe solidaire du balancier correspondant, et une partie mobile montée à pivotement par rapport à la partie fixe et coopérant avec la rampe d'actionnement du chariot de test, pour incliner le capteur de la première position de détection de la présence du câble vers la seconde position de détection de l'absence du câble.
- the second means for varying the gap comprise an actuating ramp arranged on a test carriage intended to cooperate with the control device to move the sensor from a first position of detection of the presence of the cable to a second position detection of the absence of the cable,
- the first sensor support means comprise a fixed part integral with the corresponding balance, and a movable part pivotally mounted relative to the fixed part and cooperating with the actuating ramp of the test carriage, for inclining the sensor of the first position detecting the presence of the cable to the second detection position of the absence of the cable.
Un tel actionnement automatique par un chariot de test spécifique et de tels moyens de support et d'actionnement évitent l'installation d'un manchon de test sur le câble,et ne nécessitent aucune intervention humaine. Il en résulte un contrôle entièrement automatique par l'intermédiaire du chariot de test passant au niveau des capteurs à contrôler. Un tel dispositif de contrôle est donc très simple d'utilisation.Such automatic actuation by a specific test carriage and such means of support and actuation avoid the installation of a test sleeve on the cable, and require no human intervention. This results in a fully automatic control via the test carriage passing through the sensors to be controlled. Such a control device is very easy to use.
La partie fixe des premiers moyens de support comporte une plaque coudée ayant un premier flanc fixé sur le balancier et parallèle aux galets, et un second flanc perpendiculaire au premier flanc et muni à son extrémité d'un axe de pivotement, articulant la partie mobile des moyens de support.The fixed part of the first support means comprises a bent plate having a first side fixed on the balance and parallel to the rollers, and a second side perpendicular to the first side and provided at its end with a pivot axis, articulating the moving part of the support means.
La partie mobile des premiers moyens de support comporte :
- une portion en saillie avec un bord arrondi, le long duquel s'appuie et glisse la rampe d'actionnement du chariot de test,
- un organe de maintien du capteur destiné à surélever le capteur par rapport à la partie fixe et à placer le capteur à proximité du câble, dans la première position de détection de la présence du câble.
- a protruding portion with a rounded edge, along which the actuating ramp of the test carriage is supported and slid,
- a sensor holding member for raising the sensor relative to the fixed portion and placing the sensor near the cable, in the first position of detecting the presence of the cable.
Des moyens de rappel élastique sollicitent la partie mobile de la position de détection de l'absence du câble vers la position de détection de la présence du câble.Resilient return means bias the movable portion of the detection position of the absence of the cable to the position of detection of the presence of the cable.

Les premiers moyens de support du capteur 11 comprennent également une seconde partie mobile, montée à pivotement par rapport à la plaque coudée 18 fixe autour de l'axe de pivotement 19. La partie mobile est, par exemple, sous la forme d'une came 20 coudée, comportant une portion 21 en saillie, s'étendant sensiblement perpendiculairement aux galets 17 du côté des chariots défilant le long de la remontée mécanique (

La rampe inférieure 24a entre en contact avec la portion en saillie 21, en glissant le long du bord arrondi 22, entraînant alors le pivotement de la came mobile 20 autour de l'axe de pivotement 19, qui entraîne alors la rotation de l'organe de maintien 23, qui éloigne alors le capteur 11 du câble 12, formant ainsi un premier angle d'inclinaison par rapport à la verticale (
Par ailleurs, le dispositif 10 comporte un ressort de rappel 26 (
Par ailleurs, le chariot de test 13 comporte également une rampe supérieure 25b, destinée à coopérer avec la partie mobile des moyens de support d'un capteur 11 d'un dispositif de contrôle 10 selon l'invention solidaire d'un balancier de compression 25, comme décrit ci-après pour la variante de réalisation décrite aux

Le fonctionnement du dispositif de contrôle 10 du capteur 11 associé à un balancier de compression 25 est donc identique au fonctionnement du dispositif 10 associé au balancier de support 16, comme décrit précédemment. Le dispositif de contrôle 10 comporte également le ressort de rappel 26, permettant d'accompagner le retour du capteur 11 vers la position de détection de la présence du câble 12, comme représenté sur la

Le changement de position automatique et la simple inclinaison du capteur 11 par rapport au câble 12, lors du passage du chariot de test 13 au niveau du pylône associé au dispositif de contrôle 10, suffit à effectuer les tests permettant de contrôler si le capteur 11 fonctionne bien, pour qu'il soit réactif en cas de problèmes éventuels, du type déraillement ou autres, apparaissant au niveau du câble 12.Whatever the embodiment described above, such a
Un tel test permet ainsi de vérifier la sûreté de fonctionnement de l'installation de remontée mécanique à câble sans aucun démontage des capteurs 11 sur la totalité des pylônes. Il est ainsi possible de tester rapidement la ligne en faisant un test en automatique, en faisant défiler le chariot de test le long de la ligne de la remontée mécanique. En cas de défaut d'un capteur 11, le dispositif de contrôle 10 du pylône le supportant est immédiatement repéré, permettant ainsi une intervention rapide en vue de son remplacement.Such a test thus makes it possible to verify the operational safety of the ropeway lift installation without any dismantling of the
L'invention n'est pas limitée aux différents modes de réalisation décrits ci-dessus. La forme des premiers moyens de support et des deuxièmes moyens d'actionnement du dispositif de contrôle 10 peut être différente, tant qu'elle permet un contrôle du capteur 11 efficace, simple et sans intervention d'un opérateur.The invention is not limited to the various embodiments described above.
