Definitions

  • the present invention is about an elevator without the machine room having considerable innovative characteristics.
  • the main factors to respect to satisfy these requirements are to support the traction machinery on the elevator car and/or counterweight guides, and to use a fast and small motor, and therefore of reduced cost.
  • the elevator system is shown in its direct drive version 1:1, but it can also be used in suspension in 2:1, 3:1 or 4:1 ratio.
  • the elevator car 12 travels across guide rails 14, while the counterweight 16 travels across counterweight rails 18.
  • the elevator car 12 has its car door 20 obviously turned towards the floor's door 22, but it is possible to have up to three car doors.
  • the entire elevator system is self-bearing, since both the traction machinery and the control board 24 are supported and fixed to the elevator car guide rails 14 (but it is also possible to fix them to the counterweight rails 18) through beams 26 and 28.
  • To the upper beam 26 the control board 24 is fixed and the motor 30 is suspended through tie-rods 32.
  • the motor 30 can be of the permanent magnet type, brushless, or of the asynchronous type and even gearless.
  • the control board 24, arranged in the elevator shaft allows to reduce the number of devices placed into the required external control board, and therefore its overall dimensions.
  • the traction machinery By means of the supporting frame 34, on the lower beam 28 the traction machinery is mounted, comprising the traction sheave 36, the brake 38 and the driving sheave 40, which receives motion from the motor's 30 driven sheave 41 through a reduction unit, comprising a double intermediate sheave 42A, 42B (Fig. 2 and 4).
  • a reduction unit comprising a double intermediate sheave 42A, 42B (Fig. 2 and 4).
  • the motor 30, if of permanent magnet type, has also the generator function, to recover energy when the unbalance between elevator car and counterweight is such that torque is not required from the motor, but the motor must exert a braking couple.
  • the recovered energy can also be stored in storage buffer battery floating with the power supply and with the motor's recovering circuit, so with low power employed and absolute safety in case of energy cut-off, very useful to return to the floor, especially for hospitals and other essential public and/or private services.
  • the emergency or rescue handling can be provided by an auxiliary motor or by a coaxial spare motor for the main one, suitable for moving the elevator car in emergency situations, in case of failure, breakdown or even in case of energy cut-off.
  • Essential feature is that the auxiliary or spare motor 30A, or the second motor 30B, are coaxial with the main motor, to be connected to the reduction unit and to the electromagnetic brake, without requesting further transmission elements.
  • the auxiliary motor shall be asynchronous, or brushless of permanent magnet type, or of other type, however suitable for moving the elevator system, fed by battery and/or inverter.
  • the driving unit is substantially placed inside the space extension overhead of the elevator shaft required for the counterweight, safety distance included, in direction of the counterweight thickness.
  • a control panel is combined with the driving unit, including motor and controls power supply equipments, which operate the traction sheave, being this control panel preferably integrated with the driving unit.
  • the driving unit although keeping all the elevator system characteristics mentioned above, can exceed the counterweight thickness and can also be fixed to a shaft wall and/or ceiling.
  • the counterweight suspension can also be of different type from the elevator car's one.
