Definitions

  • the present invention relates to an elevator apparatus of a self-propelled type in which a car with a drive unit mounted thereon is driven to move up and down in a hoistway.
  • the rotation shafts of the sheaves being driven to rotate by the driving force of the drive unit are disposed in the horizontal manner, so the dimension in a heightwise direction of the entire car becomes larger in accordance with the increasing outer diameter of the drive unit or the each sheave. As a result, it becomes difficult to make the space saving of the hoistway, and the elevator apparatus is made large-sized.
  • the present invention is intended to obviate the problems as referred to above, and has for its object to obtain an elevator apparatus which is capable of making the space saving of a hoistway.
  • An elevator apparatus includes a car being movable up and down in a hoistway, and a driving and hanging unit which includes: a main rope unit that has first and second main ropes, with individual upper end portions of the first and second main ropes being fixedly attached to an upper portion of the hoistway so as to hang the car; a pair of car hanging pulleys that are mounted on the car so as to guide the first and second main ropes from the individual upper end portions in horizontal directions, respectively; a drive unit that is mounted on the car and includes a drive sheave around which the first and second main ropes from the individual car hanging pulleys are respectively wrapped; and a pair of wrap pulleys that are mounted on the car so as to guide the first and second main ropes from the drive sheave in directions downwardly of the car, respectively, whereby the car is caused to move up and down in accordance with the rotation of the drive sheave; wherein the drive sheave is driven to rotate around a rotation shaft that is disposed along a vertical direction.
  • Fig. 1 is a perspective view that shows an elevator apparatus according to a first embodiment of the present invention.
  • Fig. 2 is a top plan view that shows the elevator apparatus of Fig. 1 .
  • a pair of guide rails 2, 3 are installed in a hoistway 1 ( Fig. 2 ).
  • a car 4 is disposed between the individual guide rails 2, 3 so as to be movable up and down.
  • the car 4 is hung in the hoistway 1 by mean of a main rope unit 7 that has a plurality of first main ropes 5 and a plurality of second main ropes 6.
  • An upper end portion 5a of each first main rope 5 and an upper end portion 6a of each second main rope 6 are fixedly attached to upper portions of the hoistway 1, respectively.

  • the winch 8 is designed to be a thin one having a diametrical dimension larger than an axial dimension.
  • a pair of car hanging pulleys 11, 12 for guiding the first and second main ropes 5, 6 from the individual upper end portions 5a, 6a in horizontal directions, respectively, and a pair of wrap pulleys 13, 14 for guiding the first and second main ropes 5, 6 extended in the horizontal directions downwardly of the car 2, respectively, are mounted on a lower edge portion of the car 4.

  • the first and second main ropes 5, 6 from the drive sheave 10 are guided downwardly of the car 2 by means of the individual wrap pulleys 13, 14, respectively.
  • each first main rope 5 is wrapped from its upper end portion 5a around the one car hanging pulley 11, the drive sheave 10 and the one wrap pulley 13 in this order to extend to reach its lower end portion 5b.

  • the vertical positions of the other car hanging pulley 12 and the other wrap pulley 14 with respect to the car 4 are adjusted in such a manner that the portions of the second main ropes 6 being wrapped around the drive sheave 10 are arranged to be horizontal. That is, the car hanging pulley 12 and the wrap pulley 14 are disposed in such a manner that the height of a lower portion of the car hanging pulley 12 and the height of an upper portion of the wrap pulley 14 coincide with each other.
  • a driving and hanging unit 17 has the main rope unit 7, the winch 8, the pair of car hanging pulleys 11, 12, and a pair of wrap pulleys 13, 14.
  • the drive sheave 10 is driven to rotate in a counterclockwise direction (a direction to pull the first and second main ropes 5, 6 from the individual car hanging pulleys 11, 12 to the drive sheave 10, i.e., a direction A), as shown in Fig. 2 .
  • the first and second main ropes 5, 6 are respectively caused to move from the individual car hanging pulleys 11, 12 to the drive sheave 10 (i.e., move in a direction B), and further move from the drive sheave 10 to the individual wrap pulleys 13, 14, respectively (i.e., move in a direction C).
  • the car 4 is driven to move in the upward direction.
  • the drive sheave 10 When the car 4 is to be moved in a downward direction, the drive sheave 10 is driven to rotate in a direction opposite to the above-mentioned direction. As a result, an operation opposite to the above-mentioned one is carried out, so that the car 4 is driven to move in the downward direction.
  • a driving torque Tq being generated by the winch 8 so as to move the car 4, is represented by the following expression (1).
  • Wc is the mass of the car 4
  • CAP is the loading mass of the car 4
  • D is the diameter of the drive sheave 10.
  • the driving torque Tq becomes larger in accordance with the increasing mass Wc and the loading mass CAP of the car 4.
  • a horizontal thrust force is applied to the guide rails 2, 3 from the car 4 in accordance with the rotation of the drive sheave 10, so when the driving torque Tq increases, the contact resistance of the car 4 and the guide rails 2, 3 becomes larger, and hence the running resistance of the car 4 also becomes large.
  • the car 4 is provided with the winch 8 that has the drive sheave 10 to be rotated about its rotation shaft disposed along the vertical direction, the pair of car hanging pulleys 11, 12 that guide the first and second main ropes 5, 6 from the individual upper end portions 5a, 6a thereof in the horizontal direction, and the pair of wrap pulleys 13, 14 that guide the first and second main ropes 5, 6 wrapped from the individual car hanging pulleys 11, 12 around the drive sheave 10 downwardly of the car 4.
  • the winch 8 that has the drive sheave 10 to be rotated about its rotation shaft disposed along the vertical direction, the pair of car hanging pulleys 11, 12 that guide the first and second main ropes 5, 6 from the individual upper end portions 5a, 6a thereof in the horizontal direction, and the pair of wrap pulleys 13, 14 that guide the first and second main ropes 5, 6 wrapped from the individual car hanging pulleys 11, 12 around the drive sheave 10 downwardly of the car 4.
  • the individual car hanging pulleys 11, 12 are disposed in symmetry with respect to the rotation shaft of the drive sheave 10
  • the individual wrap pulleys 13, 14 are also disposed in symmetry with respect to the rotation shaft of the drive sheave 10, so the loads, which are received by the rotation shaft of the drive sheave 10 from the first and second main ropes 5, 6, respectively, can be counterbalanced or offset with each other.
  • the loads applied to the rotation shaft of the drive sheave 10 can be reduced, and the reduction in the size of the winch 8 can be made.
  • tensions are applied to the first and second main ropes 5, 6 by the first and second weights 15, 16, so it is possible to prevent the first and second main ropes 5, 6 from coming off the drive sheave 10, the individual car hanging pulleys 11, 12 and the individual wrap pulleys 13, 14, respectively.
  • the slippage of the drive sheave 10 with respect to the first and second main ropes 5, 6 can be prevented, so the driving force of the winch 8 can be transmitted to the first and second main ropes 5, 6 in an efficient manner.
  • first and second weights 15, 16 are hung on the first and second main ropes 5, 6, so tension can be given to the first and second main ropes 5, 6 with a simple construction.
  • first and second weights 15, 16 are arranged at the individual lower end portions 5b, 6b of the first and second main ropes 5, 6, respectively, independently of each other, so even when a difference occurs in expansion of the individual main ropes 5, 6 for example, tensions can be independently given to the individual main ropes 5, 6, respectively, whereby it is possible to prevent the occurrence of an offset in the individual tensions of the first and second main ropes 5, 6.
  • the winch 8 is arranged at the lower portion of the car 4, so the overhead dimensions of the hoistway 1 can be decreased.
  • first and second main ropes 5, 6, respectively by means of mutually independent first and second weights 15, 16 tension(s) may be given to the first and second main ropes 5, 6, respectively, by means of a common weight (tension unit) which is connected with the first and second main ropes 5, 6.
