Definitions

  • a known installation of the kind mentioned is equipped with a control ramp which exerts on the clamp control member, closed on the cable, a predetermined elastic force just lower than the normal force of opening of the clamp.
  • the movement of the control lever under the action of this lower force indicates a failure of the clamp closing spring, but the reverse is not ensured. Failure to move the control lever may result from seizure or any other incident and this check is not of absolute safety.
  • This control is also of the all or nothing type and does not allow monitoring of the development of the state of the clamp.
  • the present invention aims to allow the realization of a device for almost direct measurement of the clamping force of the clamp at each outlet of the clamp from a station and without stopping or slowing down the clamp.
  • control means comprises a device for continuous measurement of the action exerted by the control member on the ramp and a detector of the moment of closing of the clamp on the cable to carry out a measurement of said action at this instant.
  • the action on the ramp is generated by the force of the closing spring which keeps the lever in support of the ramp and it is understood that this action is equivalent to the force of the spring reduced by friction and possibly affected by a multiplication factor due to levers.
  • a measurement of the action therefore constitutes a safe weighted measurement of the force of the spring.
  • the invention is advantageously applied to a clamp of the type described in French patent N ° 2497750, in which the movable jaw is pivotally mounted and is carried by one end of the actuation lever, the other end of which carries the member. and is directly attacked by the clamp closing spring.
  • This direct connection by the actuating lever between the spring, the control member and the movable jaw ensures perfect equivalence between said action, just before the clamp is closed and the clamping force exerted on the cable by the jaw at closing time.
  • the action on the ramp is transferred to the cable and the control member leaves the ramp.
  • the clamp rolls on a rail, which diverges with the control ramp so as to allow the spring to relax during the advancement of the clamp and a clamp closure.
  • the measurement area is limited to the ramp section corresponding to the closing of the clamp and the length of this section is sufficient to take into account the wear of the clamps and of the cable and the manufacturing tolerances.
  • the transfer of the force from the ramp to the cable can be detected by the separation of the control member and the ramp, in particular by providing a conductive track on the ramp, in electrical contact with the control member, the separation of which interrupts the circuit.
  • the measurement adopted is that which precedes the interruption of the electrical circuit.
  • the transfer of force can be detected by other means, for example by immobilizing the control lever or by analyzing the variation of the measurement signal.
  • the measurement is advantageously carried out by supporting the measurement section of the ramp by load cells or by a balance, but other means are conceivable.
  • the device is particularly simple and is applicable to standard pliers without any adaptation. It is intrinsically safe and its simplicity gives it great reliability.
  • a cable 10 of a single-cable air transport installation in particular of a chairlift or a gondola, is driven continuously.
  • the loads in this case the seats or the cabins, are fixed to the cable 10 in line by clamps 11 of the disengageable type to allow opening of the clamp in the stations and boarding or disembarking at a standstill or at reduced speed, passengers in seats or cabins.
  • the seats or cabins are re-accelerated and re-coupled by closing the clamp on the cable 10
  • the clamp 11 shown in Figure 1 has an elongated body 12 on which is articulated the end of a hanger 13 carrying the load (not shown).
  • the body 12 also carries rollers 14 for rolling on support rails 15 in the stations.
  • One of the ends of the body 12 is shaped as a fixed jaw 16, which cooperates with a movable jaw 17, articulated on the fixed jaw 16 and integral with the end of a control lever 18.
  • the opposite end 19 of the lever 18 carries an axis 21 of articulation of a control roller 20 and an axis 22 of anchoring of a coil compression spring 23.
  • the opposite end of the spring 23 is supported on a cup 24 secured to the body 12 by tie rods 25.
  • a friction plate 27 is fixed on the body 12 to cooperate with friction wheels 28, which drive the clamp 11 uncoupled from cable 10 in stations.
  • Such pliers are well known and it suffices to recall that the spring 23 biases the lever 18 anticlockwise, in FIG. 1, in the clamping direction of the jaws 16, 17 on the cable 10.
  • L opening of the clamp 11 is controlled by a downward movement of the roller 20 against the force of the spring 23. This control results from a passage of the clamp 11 under a control ramp 26 which engages the roller 20
  • the ramps 26 are arranged on the one hand at the entrance to the station. for uncoupling the clamp 11, rolling on the rail 15, from the cable 10 and on the other hand at the outlet for re-coupling the clamp 11 to the cable 10.
  • FIGS. 2 and 3 which illustrate a zone for clutching the clamp 11 at the outlet of the station
  • the clamp 11 rolling on the rail 15 while being driven by the friction wheels 28, engages by its roller 20 the entry of the ramp 26 in the position 6.
  • the clamp 11 is still closed, but continuing its travel in the direction indicated by the arrow in the figure the roller 20 is moved downwards by the action of the ramp 26 which approaches the rail 15.
  • position 7 the clamp 11 is open and the cable 10 engages between the jaws 16,17 open.
  • At this position 7 corresponds an inversion of slope of the ramp 26, which progressively deviates from the rail 15 allowing a rise of the roller 20 and a closing of the clamp 11 under the action of the spring 23.
  • the section 30 of the ramp 26, which extends along the closing area of the clamp 11, is mechanically separated from the other fixed part of the ramp and is carried by load cells 31 measuring the force or the action exerted by the roller 20 on the section 30. It is clear that the whole of the ramp 26 can be arranged for such a measurement and that this can be carried out by other means, in particular a simple balance . In the example illustrated in FIG. 5, the section 30 is mounted to slide upwards, other arrangements being possible.
  • the roller 20 is disposed in line with the spring 23 and that when the roller 20 is in support of the section 30 the force of the spring 20 is directly transmitted to the section 30 with the closest friction, which can be summed up moreover to those of the lever joint 18.
  • the roller 20 leaves the section 30 and all the force of the spring 23 is transferred to the jaws 16.17, well heard multiplied in a constant ratio by the lever 18. It is understood that the clamping force of the jaws 16.17 on the cable 10 corresponds exactly to that exerted on the section 30 at the time of separation of the roller 20 from the section 30 with a given weighting factor
  • the instant of separation of the roller 20 and the section 30 can be deduced from the curve, represented in FIG. 4, from the action exerted on the ramp 26 and more particularly from the point 32 of abrupt variation towards the zero value.
  • a microprocessor or any other automatic device detects this variation as well as the measurement preceding this variation to provide an exact indication of the clamping force of the clamp 11.
  • the mechanical separation causes an interruption of the electrical contact that is easily detectable and usable to initiate the measurement and possibly an alarm and a shutdown of the installation.
  • the invention is applicable to other types of clamps, in particular to two stable positions, the clamp remaining open in the station.
  • the ramp has only one closing section associated with an unlocking system, which does not affect the measuring device.
  • the relationship between the spring force and the cable clamping force is not affected by a more sophisticated lever system.
  • the measuring device is integrated into the clamp control ramp and does not increase the size of the station. It can easily be added to existing installations, without any modification of the clamps and can be improved to monitor the evolution of the spring force and therefore the state of the clamp.
