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.
