Definitions

  • the object of the invention is to provide a grinder drive device which has increased safety and this with simple means.
  • the subject of the invention is a drive device of the indicated type, characterized in that the drive device comprises safety means adapted to prevent the starting of all the training sets when at least a training set is unavailable.
  • the single figure shows schematically a mill according to the invention, designated by the general reference 2.
  • the mill 2 is a vertical mill which comprises a grinding table 4, several grinding rollers 6 and a driving device 8 of the grinding table 4 in rotation.
  • the grinding table 4 is rotatable about a vertical axis X-X.
  • the driving device 8 comprises a ring gear 10 fixed in rotation around the axis X-X of the grinding table 4.
  • the driving device 8 also comprises drive assemblies 12 of the ring gear 10.
  • the drive device 8 comprises three drive assemblies 12.
  • the mill 2 and the drive device 8 do not include other means for driving the ring gear 10 or the grinding table 4.
  • the means for driving the ring gear 10 in rotation around the axis XX are thus constituted by the training sets 12.
  • At least two, and especially all drive units 12 are identical.
  • Each drive assembly 12 comprises an electric motor 14 and a gearbox 16.
  • the electric motor 14 comprises an output shaft 18 which is connected to a not shown input shaft of the gearbox 16.
  • the gearbox 16 comprises a gear outlet 20 which meshes directly with the ring gear 10.
  • the driving device 8 also comprises a control device 22 comprising a power supply module 24 which is connected by a power supply line 26 to each of the electric motors 14.
  • the power supply module 24 is adapted to run the electric motors 14.
  • the driving device 8 also comprises safety means adapted to prevent starting or starting of all the drive assemblies 12 when at least one drive unit 12 is unavailable or faulty.
  • the security means comprise detection means Failure means adapted to detect a failure of each drive assembly 12.
  • the safety means also comprise a control means adapted to prevent the starting or starting of all the electric motors 14 in response to a failure detection by the sensors. failure detection means.
  • the failure detection means comprise engine failure detection means, which are provided, for each electric motor 14, on the one hand with an electric motor failure sensor 28 adapted to detect a failure of the associated electric motor 14 and, on the other hand, a signal line 30.
  • the motor failure detection means further comprise an evaluation module 32 for the failure state of the electric motors 14. Each signal line 30 is connected to this evaluation module 32.
  • the evaluation module 32 is adapted to detect the state of failure of one or more electric motors 14 via the electric motor failure sensors 28 and the signal lines 30 and 30. is adapted to emit an engine failure signal to the power supply module 24.
  • the power supply module 24 is adapted to prevent the supply of all the electric motors 14 in response to this signal.
  • the failure detection means comprise gear reducer detection means, which are provided, for each reducer 16, on the one hand with a gear reducer sensor 34 adapted to detect a failure of the associated reducer 16, and on the other hand, a signal line 36.
  • the gear failure detection means comprises an evaluation module 38 of the failure state of the gearheads 16.
  • the evaluation module 38 is adapted to detect the state of the gearbox. failure of one or more reducers 16 via the gearhead failure sensors 34 and the signal lines 32 and is adapted to output a gearing failure signal to the power supply module 24.
  • the power supply module 24 is adapted to prevent the supply of all the electric motors 14 in response to this signal.
  • the invention operates in the following manner.
  • the evaluation module 32 or 38 concerned emits a fault signal to the module.
  • supply 24 which, in response to this signal, blocks the start-up or start-up of each of the electric motors 14, so that during the failure of an electric motor 14 or a gear 16, none of the drive units 12 is turned on.
  • the use of the components outside their nominal capacity in the event of failure of a component is prevented.
  • the motor failure sensors 28 may for example be a current sensor indicating the presence or absence of current in the motor coils or a force or torque sensor indicating the presence or absence of force at the shaft. output 18.
  • the gearbox failure sensor 34 may be a force or torque sensor indicating the presence or absence of force or torque at a shaft of the gearbox or output gearwheel 20.
  • the control device 22 can be implemented by computer, PLC or any other means.
