Definitions

  • the present invention relates to a traction-type elevator system wherein a hoisting device is used, and particularly to an elevator system wherein the hosting device is mounted on a counterweight.
  • JP 2000 255 932 A discloses an elevator which is capable of reducing the size of a hoistway with respect to earlier elevators.
  • the electric motor of the axial gap type is provided so that the stator and the rotor face each other in the direction of the rotation axis of the rotor via an air gap; and for example, in Japanese non-examined laid-open patent publication No. Hei 7-137963 , an elevator system wherein a hoisting machine using this axial gap type electric motor is mounted on the counterweight, is disclosed.
  • the radial gap type electric motor is mounted so that the stator and the rotor face each other in the direction vertical to the direction of the rotation axis of the rotor via an air gap; and conventionally, also this radial gap type electric motor has been used in hoisting machines.
  • the external form of the hoisting machine i.e. the radial diameter and the thickness of the hoisting machine in the direction of the rotation axis of the drive sheave of the hoisting machine become large.
  • the radial gap type electric motor in the case where the torque of the electric motor used for the hoisting machine is to be increased, generally, the thickness of the rotor and the stator in the direction of the rotation axis of the rotor are increased. In accordance with this, the thickness of the hoisting machine in the direction of the rotation axis of the drive sheave becomes large.
  • the hoisting machine even if an electric motor of the axial gap type or the radial gap type is used, in order to increase the torque of the hoisting machine according to the increase in capacity of the elevator, the hoisting machine will not fit inside the frame body of the counterweight unless the dimensions of the frame body of the counterweight are not increased, because of the enlargement of the hoisting machine. As a result of this, there is a problem that the space required inside the hoistway is enlarged according to the increase in the area of the horizontal projection view of the hoistway.
  • the present invention was devised to solve the above-mentioned problems, and has as its intension to provide an elevator system capable to cope with increase to large capacity of the elevator without causing enlargement of the area of the horizontal projection view of the hoistway, i.e. the space required for the hoistway in a building, wherein the hoisting machine is mounted on the counterweight in an elevator.
  • the elevator system in the present invention comprises an elevator car which ascends and descends through the hoistway, a counterweight which travels in the direction opposite to the elevator car, and a main rope which suspends the elevator car and the counterweight; and the elevator car and the counterweight are driven by a hoisting device around which the main rope is passed.
  • the hoisting machines used in the hoisting device comprises a drive sheave around which the main rope is passed and an electric motor which drives the drive sheave to rotate.
  • the hoisting device comprises at least two of these hoisting machines, and at least one thereof is mounted on the counterweight.
  • an elevator capable to correspond to the elevator's increase to large capacity without causing enlargement of the area of the horizontal projection view of the hoistway, i.e. the space required for the hoistway in a building. Also, it is possible to serialize with facility elevators of capacities of small ranges to large ranges by simply adjusting the number of hoisting machines by construction using hoisting machines of the same specifications.
  • Figure 1 is a diagram showing an example of an arrangement of the elevator system in accordance with the first embodiment of the present invention; and is a conceptual drawing showing the elevator car and the counterweight, which are suspended by the elevator main rope, being driven to ascend and descend the hoistway by the hoisting device that is mounted on the counterweight, by expanding the elevation of the elevator system viewed from the horizontal direction of the hoistway.
  • Figure 2 is a plan view of the elevator system in accordance with Figure 1 ; and in Figure 2 , illustration of the deflector sheave and the main rope is omitted because the drawing is used mainly as a drawing to explain the arrangement of the hoisting device mounted on the counterweight and the arrangement of the relation between the elevator car and the counterweight.
  • a hoisting device 10 around which a main rope 9 is passed and which drives the elevator car 4 and the counterweight 3 is mounted on the counterweight 3.
  • the hoisting device 10 is comprised of two hoisting machines 11; and the torque required for driving the elevator is shared between the two hoisting machines 11.
  • Each of the hoisting machines 11 has a drive sheave 12 around which the main rope 9 is passed, and an electric motor 13 which drives the drive sheave 12 to rotate; and the thickness D in the direction of the rotation axis of the drive sheave 12 is formed so as to be smaller than the dimension C in the direction of the external diameter.
  • the two hoisting machines 11 are mounted inside the frame body of the counterweight 3 which constructs the external form thereof so as to overlap each other not in the horizontal direction, but in the vertical direction.
  • the form of the section of the counterweight 3 in the horizontal direction is short in the direction of the gap between the car 4 and the wall surface 1a; and the counterweight 3 has a long rectangular section in the width direction of the car 4 and also a rectangular parallelpiped external form which is formed long in the vertical direction. That is, the counterweight 3 is arranged so as to take up as little space as possible in the horizontal projection view of the hoistway 1.
  • the external form of the counterweight 3 is constructed of a frame body; and a weight for the counterweight is mounted in a lower part of the frame body.
