Definitions

  • the transfer circuit connecting the rising and falling channels of the cable comprises a slowing section equipped with a retarder device, an acceleration section equipped with a launcher device, connected by a low speed traffic contour section equipped with a vehicle driving device.
  • the assembly formed by the acceleration device, the launcher device and the drive device constitutes the means for moving the vehicle along the transfer circuit.
  • the displacement means consist of one or more tire train (s) staggered along the transfer circuit, to cooperate by friction with a friction track carried by the clamps of the vehicles.
  • Each of these wheel sets is equipped with drive means ensuring the rotation of each wheel of the train by one of the adjacent wheels.
  • These drive means often include drive belts or idler gears.
  • one of the wheels of this train can be connected to a power take-off derived from the movement of movement of the cable.
  • a power take-off is in particular carried out by means of a rotary roller bearing on the cable and set in motion by the running of the cable.
  • variable speed motor which drives a transmission belt stretched between two pulleys, one of which is mounted coaxially on one of the wheels, or on the one of the idle gears when the drive means comprise such gears.
  • the number of vehicles supported by a given set of wheels is variable.
  • the power required to move these vehicles is logically proportional to the number of vehicles.
  • the instantaneous power recovered from the cable by the PTO of this train is function of the coefficient of adhesion between the cable and the roller and the normal force exerted by the cable on the roller.
  • the first factor depends on the type of tire (modulus of elasticity), temperature, external conditions (humidity, frost).
  • the second factor depends on the cable tension, the angle of deflection of the cable on the roller, and the maximum load allowed by the roller.
  • the instantaneous power recovered from the cable by the power take-off and transmitted to the wheel set shall at all times be equal to the sum of the power required for the displacement vehicles on this train and lost power especially because of the yields and reduction ratios of the mechanics used. Otherwise, this results in a sliding of the rotary roller of the PTO relative to the cable.
  • the risk of occurrence of this slip is very high when the flow of the facility is high and / or when the external conditions are unfavorable, which is not satisfactory for operators.
  • the only way to overcome this risk is to oversize the power take-off and / or exaggerate the number of wheel sets in order to increase the number of power take-offs on the transfer circuit, resulting in an increase in costs of manufacturing, installation and maintenance of the facilities.
  • the document EP0461954 describes a transport installation in which the means for moving the vehicles in the disengaged state comprises at least two consecutive sets of wheels.

  • the power transmitted to the means of movement of the vehicles comes, at each moment, on the one hand from the PTO derived from the running of the cable and the other electric torque motor.
  • the power delivered by the torque motor being equal to the multiplication of the torque supplied, which is of constant value, and the rotational speed of the output shaft, the torque motor thus transmits a power of constant value to the means of displacement.
  • the rest of the power required is provided by the PTO.

  • the power from the power take-off P1 is therefore variable as in the prior art, but decreased by a value equal to the constant power delivered by the torque motor 26, which makes it possible to be very easily freed from any risk. sliding of the rotary roller of the PTO P1 relative to the cable 10.
  • the torque motor 26 also has the advantage of delivering a constant torque regardless of the running speed of the cable 10 and without requiring any additional electronic device or even servo device. Thus, the torque motor 26 performs its function, in degraded operation of the installation, by a simple power supply. On the other hand such a torque motor 26 has the advantage of being able to be installed very simply and for a lower cost on new or existing installations.
  • the choice of the wheel of the first train which is linked to the torque motor 26 has an importance on the operation of the first train.

  • Such a configuration makes it possible, in the absence of vehicles 12 on the first set of wheels and for the most unfavorable climatic conditions, to limit the risk that the power supplied by the torque motor 26 does not exceed the dissipation capacity of energy by the drive means of the wheels of the train and by the friction of the rotary roller of the power take-off P1 on the cable 10. Such an overshoot would cause a slippage of the belts 18A, 18C1 and / or the rotary roller. Nevertheless, the choice of the wheel of the first train to which the torque motor 26 is linked is not limiting of the invention. In other words, the torque motor 26 may be connected to any wheel 17A, 17C1, possibly 17C2, without departing from the scope of the invention.
  • the second set of wheels defined above can also be equipped with a torque motor (not shown) connected to one of its wheels 17B, 17C3 and possibly 17C2.
  • the means of movement of the vehicles 12 along the transfer circuit comprise two sets of wheels, each of which comprises a wheel linked to a respective motor-torque and a wheel linked to a respective PTO P1, P2.
  • the torque motor associated with the second set of wheels may be connected to one of the first wheels 17C3 (seen in the direction of travel of the vehicles 12) of the last section S3 of the contour section C reduced speed. It is clear that the number of wheel sets each of which comprises a wheel linked to a respective torque motor and a wheel linked to a respective power take-off can be greater than two without departing from the scope of the invention.
