Definitions

  • the present invention relates to an elevator having a hoisting machine disposed in an upper part of a hoistway and not in a machine room.
  • FIG. 5 is a side view showing a conventional machine-room-less elevator, as disclosed in Japanese Patent Application Laid-open No. Hei 10-81463.
  • a hoisting machine 43 is supported on counterweight guide rails 42 provided in a hoistway 41.
  • a car 44 is guided by car guide rails 45 to be elevated and lowered in the hoistway 41.
  • Japanese Patent Application Laid-open No. Hei 6-345367 discloses a simple elevator for two storey applications in which a hoisting machine is supported by a car guide rail just above a car.
  • the hoisting machine and the car are vertically projected on a horizontal plane, the hoisting machine is arranged so as to completely overlap the car. Therefore, the height from the level of an uppermost floor to the ceiling of the hoistway, that is, the overhead dimension, is increased just by the amount for the machine room.
  • an elevator comprising: a hoistway; a car and a counterweight alternately elevated and lowered in the hoistway; a rope for suspending the car and the counterweight in the hoistway; and a hoisting machine, provided in an upper part of the hoistway, including a traction sheave on which the rope is wound, a motor for rotating the traction sheave, and a reduction gear device connected between the traction sheave and the motor, for elevating and lowering the car and the counterweight through the rope; wherein when the car and the hoisting machine are vertically projected on a horizontal plane, the reduction gear device and the traction sheave are located outside an area on which the car is projected, and a part of the motor
  • Fig. 1 is a side view of an elevator according to a first embodiment of the present invention.
  • Fig. 2 is a plan view of the elevator shown in Fig. 1.
  • Fig. 1 illustrates a state in which a counterweight is lowered to its lowermost travelling position.
  • a pair of car guide rails 2 are disposed in a hoistway 1.
  • a car 3 is guided by the car guide rails 2 to be elevated and lowered in the hoistway 1.
  • the car 3 is provided with a car frame 4, a car cabin 5 supported by the car frame 4, a pair of car pulleys 6 rotatably provided at the lower part of the car cabin 5, a car door 7 for opening and closing the entrance of the car cabin 5 and a switching device 8 provided in the upper part of the car cabin 5 to drive the car door 7.
  • the car frame 4 includes a pair of vertical posts 4a and a top beam 4b fixed between the vertical posts 4a above the car cabin 5.
  • a pair of weight guide rails are provided.
  • a counterweight 10 is elevated and lowered along the weight guide rails 9.
  • a rotatable weight pulley 11 is provided at the upper part of the counterweight 10.
  • a weight buffer 12, for bearing the counterweight 10, is provided at the bottom part of the hoistway 1 .
  • Fig. 1 shows a state in which the buffer is pushed down by bearing the counterweight 10.
  • a car buffer for bearing the car 3 is not illustrated in the drawings.
  • a hoisting machine mount 13 is fixed between an upper portion of the pair of weight guide rails 9.
  • a hoisting machine 14 for elevating and lowering the car 3 and the counterweight 10 is mounted on the hoisting machine mount 13 in the upper part of the hoistway 1.
  • the hoisting machine 14 is equipped with a reduction gear device 15 mounted on the hoisting machine mount 13, a traction sheave 16 connected to the output shaft of the reduction gear device 15 and a motor 17 connected to the input shaft of the reduction gear device 15 to drive the traction sheave 16 through the reduction gear device 15.
  • the reduction gear device 15 and the traction sheave 16 are located outside the area on which the car 3 is projected, that is to say, at positions where the reduction gear device 15 and the traction sheave 16 do not overlap the car 3, and the motor 17 is located so that a part of it is arranged inside the area on which the car 3 is projected, namely at a position where the motor 17 overlaps the car 3, respectively.
  • the surface of the motor 17 facing the roof of the car cabin 5 is located above the lower ends of the reduction gear device 15 and the traction sheave 16.
  • Reference numeral 18 denotes a pair of fixing arms for fixing the reduction gear device 15 onto the side wall 1a of the hoistway 1.
  • the car 3 and the counterweight 10 are suspended in the hoistway 1 through a rope 19.
  • the rope 19 has respectively a car side end 19a fastened to the upper part of the hoistway 1 and a weight side end 19b fastened to the lower part of the hoisting machine mount 13. Further, the rope 19 is successively wound about a pair of car pulleys 6, the traction sheave 16 and the weight pulley 11 and reaches the weight side end 19b from the car side end 19a in this order.
  • Reference numeral 20 designates a hall floor
  • numeral 21 designates a hall door.
  • H1 indicates the height from the uppermost hall floor 20 to the uppermost part of the device on the car 3 (here, the roof of the car cabin 5) which comes into closest contact with a device above the car 3 (here, the motor 17) when the car 3 jumps upward.
  • d10 indicates the dimension between the roof of the car cabin 5 and the motor 17 when the car 3 jumps up.
  • M indicates the diameter of the motor 17 (specifically, about 200 mm).
  • Reference symbol d20 indicates the dimension between the uppermost part of the hoisting machine 14 (here, the motor 17) and the ceiling of the hoistway 1.
  • the height of the hoisting machine mount 13 (about 150 mm) and the height of the hoisting machine 14 (about 600 mm) will be added to the overhead dimension.
  • the diameter of the motor 17 is included in the height of the hoisting machine 14.
  • the motor 17 which is smaller than the reduction gear device 15 or the traction sheave 16 can be formed. Therefore, even when the hoisting machine mount 13 is not employed, for instance when the hoisting machine 14 is suspended from the ceiling of the hoistway 1, the overhead dimension can be decreased by (the height of the hoisting machine 14) - (the diameter of the motor 17).
  • the position of the uppermost part of the motor 17 is located at a position lower than the uppermost parts of other parts of the hoisting machine 14, the dimension from the uppermost part of the motor 17 to the uppermost part of the hoisting machine 14 is added to the overhead dimension obtained from the above-described formula.
  • the position of the uppermost part of the motor 17 is set at a position at the same height as or higher than the uppermost portions of the other parts of the hoisting machine 14, the overhead dimension can be reduced with great efficiency.
  • the floor area of the car cabin 5 can be increased relative to the area of the restricted hoistway in the elevator according to the first embodiment of the present invention.
  • the hoisting machine mount 13 on which the reduction gear device 15 is mounted is fixed to the upper ends of the weight guide rails 9, the hoisting machine 14 can be arranged by effectively using the space in the upper part of the hoistway 1.
  • the reduction gear device 15 is firmly fixed to the side wall 1a of the hoistway 1 by the fixing arms 18. More specifically, one end of the fixing arms 18 are fixed to the side wall 1a and the other end of the fixing arms 18 are fixed to the case of the reduction gear device 15, respectively. Thus, overturning of the hoisting machine 14 due to loads applied to the traction sheave 16 can be more assuredly prevented.
  • fixing arms 18 are provided between the reduction gear device 15 and the side wall 1a of the hoistway 1
  • fixing arms 31 may for instance, be provided between the reduction gear device 15 and the car guide rails 2 as shown in Figs. 3 and 4, to prevent the hoisting machine 14 from being overturned.
  • the surface of the motor 17 facing the car 3 is located above the lower ends of the reduction gear device 15 and the traction sheave 16, it should be noted that the present invention is not limited thereto, and for instance, the surface of the motor 17 facing the car 3 may be located above the lower end of the reduction gear device 15 or the traction sheave 16.
