Definitions

  • a drive unit 5 for generating a driving force to move the car 2 and the counterweight 3 up and down is arranged in the machine room 4.
  • the drive unit 5 is designed to be a thin winch that is larger in its diametrical dimension than in its axial dimension.
  • the drive unit 5 has a flat drive unit main body 6 including a thin motor, and a drive sheave 10 that is driven to rotate by the driving force of the drive unit main body 6.
  • the drive sheave 8 is driven to rotate around a rotation shaft 7 ( Fig. 2 ) that is disposed along a vertical direction.
  • the drive unit 5 is disposed in a horizontal manner so that the rotation shaft 7 is disposed along the vertical direction.
  • the drive unit 5 is arranged such that the drive sheave 8 is at a location above the drive unit main body 6.
  • the horizontal defection wheel 15 is able to rotate around a rotation shaft which is disposed along the vertical direction.
  • portions of the individual first main ropes 9 between the drive sheave 8 and the first weight side deflection wheel 13 are wrapped around the horizontal defection wheel 15.
  • the horizontal defection wheel 15 is disposed at a location more away from the first weight side deflection wheel 13 than the drive sheave 8, in a vertical projection plane of the hoistway 1.
  • the first and second car rope stop members 16, 17 are disposed in symmetry with respect to the center of the car 2 in the vertical projection plane of the hoistway 1 ( Fig. 2 ).
  • the first car hanging end portions 9a are connected with the first car rope stop member 16, and the second car hanging end portions 10a are connected with the second car rope stop member 17.
  • the first and second weight rope fastening members 18, 19 are disposed in symmetry with respect to the center of the counterweight 3 in the vertical projection plane of the hoistway 1 ( Fig. 2 ).
  • the first weight hanging end portions 9b are connected with the first weight rope fastening member 18, and the second weight hanging end portions 10b are connected with the second weight rope fastening member 19.
  • the individual first main ropes 9 are wrapped, from the first car hanging end portions 9a thereof, around the first car side deflection wheel 11, the drive sheave 8, the horizontal defection wheel 15 and the first weight side deflection wheel 13 in this order to reach the first weight hanging end 9b thereof.
  • the individual second main ropes 10 are wrapped, from the second car hanging end portions 10a thereof, around the second car side deflection wheel 12, the drive sheave 8 and the second weight side deflection wheel 14 in this order to reach the second weight hanging end 10b thereof.
  • the portions of the first main ropes 9 wrapped around the horizontal defection wheel 15 and the portions of the first main ropes 9 wrapped around the drive sheave 8 are bent in opposite directions with respect to each other.
  • the first main ropes 9 are continuously wrapped around the first car side deflection wheel 11, the drive sheave 8, the horizontal defection wheel 15 and the first weight side deflection wheel 13 in a continuous manner without crossing one another in the vertical projection plane of the hoistway 1 ( Fig. 2 ).
  • first and second main ropes 9, 10 are wrapped around the drive sheave 8 in such a manner that the drive sheave 8 is clamped between the first and second main ropes 9, 10 in a plane of projection thereof along the rotation shaft of the drive sheave 8. That is, the first main ropes 9 are wrapped around an outer peripheral portion of the drive sheave 8 at a side opposite to an outer peripheral portion thereof around which the second main ropes 10 are wrapped.
  • the individual first main ropes 9 and the individual second main ropes 10 are driven to move by the rotation of the drive sheave 8.
  • the car 2 and the counterweight 3 are driven to move up and down in the hoistway 1 in accordance with the movements of the individual first main ropes 9 and the individual second main ropes 10.
  • the first and second main ropes 9, 10 respectively wrapped around the drive sheave 8 are selectively wrapped around the individual deflection wheels 11 through 14, respectively, and the common car 2 and the common counterweight 3 are hung by the first and second main ropes 9, 10 by converting or deflecting the direction of the first main ropes 9 into the horizontal direction by means of the horizontal defection wheel 15, as a consequence of which it is possible to prevent all the main ropes from being wrapped around each of the deflection wheels 11 through 14, thereby making it possible to reduce the number of main ropes wrapped around each of the individual deflection wheels 11 through 14.
  • the number of grooves in each of the deflection wheels 11 through 14 can be reduced, and the thickness of each of the deflection wheels 11 through 14 can be decreased.
  • the individual deflection wheels 11 through 14 can be brought closer to the drive sheave 8 while maintaining the angles of approach of the main ropes to the grooves in the individual deflection wheels within a predetermined range, and the reduction in the horizontal dimension of the hoistway 1 can be made.
  • first and second main ropes 9, 10 are respectively wrapped around the drive sheave 8 in such a manner that at least a part of the force received by the rotation shaft 7 from the individual first main ropes 9 and a part of the force received by the rotation shaft 7 from the individual second main ropes 10 are counteracted with each other.
  • the load which is substantially supported by the rotation shaft 7 of the drive sheave 8 can be decreased, and the reduction in size of the drive unit 5 can be made. From these reasons, it is possible to achieve the space saving of the hoistway 1.
  • the contact wrap portions 20 of the first main ropes 9 and the contact wrap portions 21 of the second main ropes 10 are disposed in symmetry with respect to the rotation shaft 7 of the drive sheave 8 in the plane of projection in a direction along the rotation shaft 7 of the drive sheave 8, so the force received by the rotation shaft 7 from the first main ropes 9 and the force received by the rotation shaft 7 from the second main ropes 10 can be counteracted with each other in an effective manner, thereby making it possible to further reduce the size of the drive unit 5.
  • Fig. 4 is a top plan view of the elevator apparatus of Fig. 3 .
  • portions of first main ropes 9 wrapped around the horizontal defection wheel 15 and portions of the first main ropes 9 wrapped around a drive sheave 8 are bent in the same direction with respect to each other.
  • portions of the first main ropes 9 between the drive sheave 8 and the first weight side deflection wheel 13 and portions of the first main ropes 9 between the drive sheave 8 and the first car side deflection wheel 11 cross each other in a vertical projection plane of the hoistway 1.
  • portions of the first main ropes 9 between the horizontal deflection wheel 15 and the first weight side deflection wheel 13 and the portions of the first main ropes 9 between the drive sheave 8 and the first car side deflection wheel 11 cross each other.
  • the first and second main ropes 9, 10 are wrapped around the drive sheave 8 in such a manner that contact wrap portions 20 of the first main ropes 9 and contact wrap portions 21 of the second main ropes 10 clamp the rotation shaft 7 therebetween in the plane of projection in the direction along the rotation shaft 7.
  • the individual positions of the contact wrap portions 20 of the first main ropes 9 and the contact wrap portions 21 of the second main ropes 10 deviate from their completely symmetrical positions with respect to the rotation shaft 7.
  • the construction of this embodiment other than the above is similar to that of the first embodiment.
  • the portions of the first main ropes 9 between the horizontal deflection wheel 15 and the first weight side deflection wheel 13 and the portions of the first main ropes 9 between the drive sheave 8 and the first car side deflection wheel 11 cross each other in the vertical projection plane of the hoistway 1, so the portions of the first main ropes 9 wrapped around the horizontal defection wheel 15 and the portions of the first main ropes 9 wrapped around the drive sheave 8 can be bent in the same direction with respect to each other, thereby making it possible to increase the life span of the first main ropes 9.
  • the drive unit 5 the first car side deflection wheel 11, the first car side deflection wheel 12, the first weight side deflection wheel 13, the second weight side deflection wheel 14 and the horizontal deflection wheel 15 are all arranged in the hoistway 1 at the upper portion thereof, so a machine room can be eliminated, and a further space saving of the hoistway 1 can be made.
  • Fig. 5 is a top plan view that shows an elevator apparatus according to a third embodiment of the present invention.
  • portions of the first main ropes 9 between a drive sheave 8 and a horizontal deflection wheel 15 and portions of the first main ropes 9 between the drive sheave 8 and a first car side deflection wheel 11 cross each other in a vertical projection plane of a hoistway 1.
  • contact wrap portions 20 of the first main ropes 9 and contact wrap portions 21 of the second main ropes 10 are only partially overlapped with each other as a main rope wrap portion 31 in the plane of projection in a direction along a rotation shaft 7.
  • the construction of this embodiment other than the above is similar to that of the second embodiment.
  • the contact wrap portions 20 of the first main ropes 9 and the contact wrap portions 21 of the second main ropes 10 are only partially overlapped with each other as a main rope wrap portion 31 in the plane of projection in the direction along the rotation shaft 7, so a contact area between each of the first and second main ropes 9, 10 and the drive sheave 8 can be made large. Accordingly, the prevention of slippage of the first and second main ropes 9, 10 with respect to the drive sheave 8 can be made.
