Definitions

  • the present invention relates to an improved operation device for elevators.
  • the invention concerns a device of the above kind for the electrical operation of an elevator.
  • the invention described in the following is directed to electrical operation elevators.
  • the Applicant has realised a device allowing to use an industrial kind ratiomotor, not exploiting the casing of the machine as second support element of the slow shaft of the traction pulley, but a real support, in such a way that the ratiomotor only has to transmit the torque.
  • Another peculiar feature of the device according to the present invention is that of providing a solution that allows to fraction the rope loading on two pulleys symmetrically laterally placed with respect to the ratiomotor.
  • an operation device for elevators comprising a motor - ratiomotor assembly, provided with an output shaft projecting from both sides of the engine, pulley means and support means, symmetrically placed on said output shaft, upper support means, to which said support means are coupled, and having at least a fixing point for said motor - ratiomotor assembly, said device being fixed above to the self-bearing structure comprised of the guides of the elevator car and by the counterweight.
  • said upper support means are comprised of a structure resting on the guides.
  • said support means are comprised of plates.
  • said motor - ratiomotor assembly is an industrial kind assembly.
  • the device according to the invention provides a motor - ratiomotor assembly 1 of the industrial kind, having a shaft, projecting from both sides.
  • Pulleys 3 and two supports 4 are symmetrically inserted on said shaft 2.
  • Said supports 4 are fixed by the plates 5, 6 to an upper cross member 7.
  • Said upper cross member 7 centrally provides a fixing point 8, to which the assembly 1 of the device according to the invention is coupled in order to prevent its rotation.
  • All the assembly 1, along with the relevant support frame 7, is fixed at the top of the self-bearing structure comprised of the car 10 guides 9 and of the counterweight.
  • the device according to the invention it is possible a ratiomotor of the industrial kind, not exploiting the casing of the machinery as second support element of the slow shaft of the traction pulley, but a real support, in such a way that the ratiomotor must only transmit the torque.
  • Another basic feature of the device according to the invention is that of fraction the rope loads on the two pulleys 3, that are symmetrically laterally placed on the ratiomotor 1.
  • the fractioning allows reducing the dimensions of the shaft 2, and consequently those of the ratiomotor 1, thus making it possible its positioning within the room without penalising the dimensions of the same with respect to a traditional system.
