Definitions

  • the present invention relates to an elevator apparatus with a drive unit arranged at an upper portion inside a hoistway.
  • a drive unit for driving a car and a balance weight to move in a vertical direction is arranged astride a car guide rail, and hence there has been the following problem. That is, in case where the drive unit is fixedly mounted to the single car guide rail, the rigidity of the mounting portion of the drive unit is reduced. In addition, in case where the drive unit is fixedly mounted to the guide rail through a mounting beam, the mounting structure of the drive unit becomes complicated.
  • a driving sheave is arranged at a location above a deflection wheel inside a hoistway, and a drive unit main body for driving the driving sheave is arranged on a car side, as a result of which there arises a problem of requiring a deflection wheel.
  • the present invention is intended to obviate the problems as referred to above, and has for its object to obtain an elevator apparatus in which a drive unit can be strongly fixed with a simple mounting structure without requiring any deflection wheel.
  • An elevator apparatus includes: a hoistway; a pair of car guide rails and a pair of balance weight guide rails installed inside the hoistway; a car that is guided along the car guide rails for vertical movement inside the hoistway; a balance weight that is guided along the balance weight guide rails for vertical movement inside the hoistway; a drive unit that includes a drive unit main body fixedly mounted to the pair of balance weight guide rails through a mounting member at an upper portion inside the hoistway, and a driving sheave adapted to be rotated by the drive unit main body, for driving the car and the balance weight in a vertical direction; a main rope that is wrapped around the driving sheave so as to hang the car and the balance weight inside the hoistway; a first car hanger wheel and a second car hanger wheel which are arranged in pair at a lower portion of the car, and around which the main rope is wrapped; and a balance weight hanger wheel which is arranged at an upper portion of the balance weight, and around which the main rope is wrapped;
  • the driving sheave of the drive unit arranged above the balance weight is disposed between a center line of the pair of balance weight guide rails and a side surface of the car, the driving sheave being also arranged above the first car hanger wheel among the first and second car hanger wheels.
  • Fig. 1 is a schematic perspective view of an elevator apparatus according to a first embodiment of the present invention.

  • Fig. 3 is a front elevational view of essential portions of the elevator apparatus of Fig. 1.
  • Fig. 4 is a cross sectional view of the elevator apparatus of Fig. 3 taken along line IV-IV thereof.
  • This elevator apparatus includes a hoistway 1, a pair of car guide rails 2 and a pair of balance weight guide rails 3 installed inside this hoistway 1, a car 4 that is guided along the car guide rails 2 for vertical movement inside the hoistway 1, a the balance weight 5 that is guided along the balance weight guide rails 3 for vertical movement inside the hoistway 1, a drive unit main body 6 in the form of a motor arranged at an upper portion inside the hoistway 1, a drive unit 8 having a driving sheave 7 adapted to be rotated by the drive unit main body 6 for driving the car 4 and the balance weight 5 to move in the vertical direction, a main rope 9 that is wrapped around the driving sheave 7 so as to hang the car 4 and the balance weight 5 in the hoistway 1, a first car hanger wheel 10 and a second car hanger wheel 11 which are arranged in pair at a lower portion of the car 4 and around which the main rope 9 is wrapped, and a balance weight hanger wheel 12 which is mounted on an upper portion of the balance weight 5 and around which
  • the driving sheave 7 of the drive unit 8 arranged above the balance weight 5 is arranged between a side surface of the car 4 and a center line A of the pair of balance weight guide rails 3, when the hoistway 1 is viewed along the vertical direction, and arranged above the first car hanger wheel 10.
  • a central axis B of the driving sheave 7 is arranged in such a manner that it orthogonally intersects the central point of the center line A of the balance weight guide rails 3.
  • a support base 13 is fixedly secured to the pair of balance weight guide rails 3.
  • a main rope end fixing beam 15 to which an end portion of the main rope 9 is fixedly attached is fixedly secured to the support base 13.
  • a mounting frame 14, which extends in the vertical direction in parallel to the balance weight guide rails 3, is fixedly secured to the main rope end fixing beam 15.
  • a pair of support portions 14a extending toward the drive unit 8 side are formed at an upper end portion of the mounting frame 14, and the drive unit 8 is fixedly attached to tip ends of the support portions 14a.
  • guide members 16, which serve to prevent the drive unit 8 from being thrown down toward the car 4 side due to the own weight of the drive unit 8 and the pushing force of the main rope 9, are fixedly mounted on upper portions and lower portions, respectively, of the mounting frame 14.
  • the support base 13, the main rope end fixing beam 15 and the mounting frame 14 together constitute a mounting member for fixedly attaching the drive unit 8 to the pair of balance weight guide rails 3.
  • the main rope 9 fixedly attached at its one end to the car side main rope stop member 17 runs in the downward direction until it meets the second car hanger wheel 11, and then makes almost a quarter turn around the second car hanger wheel 11. Thereafter, the main rope 9 runs obliquely astride the bottom of the car 4, and then makes almost a quarter turn around the first car hanger wheel 10.
  • the main rope 9 continuously runs almost in the vertical direction until it meets the driving sheave 7, and then makes almost a half turn around the driving sheave 7, after which it runs in the downward direction until it meets again the balance weight hanger wheel 12.
  • the main rope 9 makes almost a half turn around the balance weight hanger wheel 12, and again runs in the upward direction.
  • the other end of the main rope 9 is fixedly attached to the main rope end fixing beam 15.
  • the driving sheave 7 of the drive unit 8 arranged above the balance weight 5 is disposed between the center line A of the pair of balance weight guide rails 3 and a side surface of the car 4, and it is also disposed above the first car hanger wheel 10. Therefore, there is no need to arrange a deflection wheel between the driving sheave 7 and the first car hanger wheel 10.
  • the driving sheave 7 is arranged in such a manner that the central axis B thereof orthogonally intersects the center line A of the balance weight guide rails 3 at the central point thereof. As a result, an offset load applied to the drive unit 8 through the main rope 9 can be alleviated.
  • the drive unit 8 is fixedly mounted to the pair of balance weight guide rails 3 through the mounting member (comprising the support base 13, the mounting frame 14 and the main rope end fixing beam 15).
  • the drive unit 8 is strongly fixed to the balance weight guide rails 3 through the simple construction.
  • the drive unit main body 6 is arranged on the car 4 side, the drive unit main body 6 can be easily accessed from the car 4 upon maintenance and inspection of the drive unit main body 6.
  • Fig. 5 is a schematic cross sectional plan view that shows an elevator apparatus according to a second embodiment of the present invention.
  • a balance weight hanger wheel 22 is arranged inclined with respect to the driving sheave 7 so that the hanging axis of the balance weight hanger wheel 22 becomes close to the vertically extending center line of the balance weight 5.
  • the hanging axis of the balance weight hanger wheel 22 is arranged close to the vertically extending center line of the balance weight 5, when the balance weight 5 is moved upward through the balance weight hanger wheel 12, the balance weight 5 will not be easily inclined, thus facilitating smooth upward movement thereof.
  • Fig. 6 is a schematic cross sectional plan view that shows an elevator apparatus according to a third embodiment of the present invention.
