Definitions

  • a driving machine for raising and lowering the car is arranged in a pit at the bottom of the hoistway.
  • the pit When a driving machine is arranged in the pit, the pit must be made deeper in order to prevent interference between the car and the driving machine, resulting in higher building costs.
  • Fig. 1 is a plan view of an elevator apparatus according to Embodiment 1
  • Fig. 2 is a side view of the pit periphery of the elevator apparatus of Fig. 1.
  • a pair of car guide rails 2 and a pair of counterweight guide rails 3 are provided in a hoistway 1.
  • a car 4 is guided by the car guide rails 2 and is raised and lowered in the hoistway 1.
  • a counterweight 5 is guided by the counterweight guide rails 3 and is raised and lowered in the hoistway 1.
  • a pit 1a is provided at the bottom of the hoistway 1. Under the floor of a landing 6 of the lowermost floor (including the portion below the landing threshold), there is provided an installation space 7 adjacent to the pit 1a.
  • the installation space 7 accommodates a driving machine (hoisting machine) 8 for causing the car 4 and the counterweight 5 to ascend and descend.
  • the driving machine 8 has a driving sheave 9.
  • the driving machine 8 is supported by a support base 10 through the intermediation of a machine base 11.
  • a plurality of rubber vibration isolators 12 are provided between the driving machine 8 and the machine base 11.
  • a detachable partition 13 serving as both a soundproof wall and a fireproof wall.
  • the car 4 and the counterweight 5 are suspended in the hoistway 1 by a main rope 14 wound around the driving sheave 9, and are raised and lowered by the driving machine 8 through the main rope 14.
  • a car-side deflector wheel 15 In the pit 1a, there are arranged a car-side deflector wheel 15 and a counterweight-side deflector wheel 16.
  • a car-side return wheel 17 In the upper portion of the interior of the hoistway 1, there are arranged a car-side return wheel 17 and a counterweight-side return wheel 18.
  • a first end portion and a second end portion of the main rope 14 are respectively connected to a rope locking portion (not shown) in the upper portion of the interior of the hoistway 1.
  • the main rope 14 is sequentially wound around the car suspending wheels 20 and 19, the car-side return wheel 17, the car-side deflector wheel 15, the driving sheave 9, the counterweight-side deflector wheel 16, the counterweight-side return wheel 18, and the counterweight suspending wheel 21, and ends at the second end portion.
  • the installation space 7 is provided under the floor of the landing 6 of the lowermost floor, and the driving machine is accommodated in this installation space 7, with the result that it is possible to prevent interference between the car 4 and the driving machine 8 without making the pit 1a deeper, thereby achieving a reduction in building cost. Further, since the underfloor portion of the landing 6 is generally not utilized in many cases, it is relatively free from restrictions and can be effectively utilized as the installation space 7.
  • Fig. 3 is a side view showing the pit periphery of an elevator apparatus according to Embodiment 2 of this invention.
  • the driving machine 8 is supported by a machine base 22.
  • the machine base 22 is supported by a support base 23 and is capable of sliding reciprocatingly between the installation space 7 and the pit 1a.
  • a screw shaft 24 Between the support base 23 and the machine base 22, there is provided a screw shaft 24, which is threadedly engaged with a screw shaft support member 25 secured to the support base 23. Otherwise, the construction of this embodiment is the same as that of Embodiment 1.
  • Fig. 5 is a plan view of an elevator apparatus according to Embodiment 3 (not part of this invention), and Fig. 6 is a side view showing the pit periphery of the elevator apparatus of Fig. 5.
  • Fig. 6 is a side view showing the pit periphery of the elevator apparatus of Fig. 5.
  • Embodiment 3 a long and narrow driving machine 30 is used.
  • the driving machine 30 is arranged vertically so that the rotation shaft of its driving sheave 31 extends in the vertical direction.
  • the installation space 32 is large enough to perform maintenance on the driving machine 30.
  • a control panel 33 is arranged in the operation space 32. Otherwise, the construction of this embodiment is the same as that of Embodiment 1.
  • the partition 13 is removed from the pit 1a side, whereby it is also possible to inspect the driving machine 30 from the pit la side.
  • the operator can enter the installation space 32 safely and easily from the landing 6 to inspect the driving machine 30. Further, by removing the partition 13 from the pit 1a side, it is also possible to inspect the driving machine 30 from the pit 1a side.
  • the operator can enter the installation space 32 safely and easily from the landing 6 to inspect the driving machine 34. Further, by removing the partition 13 from the pit 1a side, it is also possible to inspect the driving machine 34 from the pit 1a side.
  • Embodiment 5 the driving machine 34 is arranged horizontally, it is also possible, as shown in Fig. 11, to arrange the driving machine 34 vertically so that the rotation shaft of the driving sheave 35 may extends in the vertical direction.
  • Fig. 12 is a side view showing the pit periphery of an elevator apparatus according to Embodiment 7 of this invention.
  • the control panel 33 is mounted on the driving machine 30.
  • the top side of the installation space 32 is opened by removing two covers 28a and 28b.
  • the driving machine 30 and the control panel 33 are supported by the machine base 11 through the intermediation of a moving base 36 capable of moving vertically relative to the machine base 11, a swinging base 37 swingable around a shaft 38 relative to the moving base 36, and a plurality of rubber vibration isolators 12.
  • a screw rod 42 for vertically moving the moving base 36 is connected to the moving base 36 at the time of maintenance.
  • a handle 43 for rotating the screw rod 42 is connected to the upper end portion of the screw rod 42.
  • the screw rod 42 is supported by a screw reception base 44.
  • the screw reception base 44 is secured in position in the vicinity of the landing threshold by a mounting bolt 45 at the time of maintenance.
  • the driving machine 30 can be moved to a position on the floor of the landing 6 at the time of maintenance, with the result that that the operator can perform maintenance operations at the landing 6 without entering the installation space 32, whereby an improvement can be achieved in terms of operational efficiency.
  • the operation of the elevator is stopped, and the driving machine 30 and the control panel 33 are raised beforehand, whereby it is possible to prevent the driving machine 30 and the control panel 33 from being flooded in water.
  • the maintenance operation can be conducted at the landing 6, thereby achieving an improvement in terms of operational efficiency. Further, the driving machine 30 and the control panel 33 can be automatically prevented from being flooded in water.
  • Fig. 20 is a side view showing the pit periphery of an elevator apparatus according to Embodiment 11 of this embodiment
  • Fig. 21 is a side view showing a state in which the driving machine of Fig. 20 has been moved onto the floor of the landing.
  • the driving machine 8 is supported by the machine base 11 through the intermediation of slide guides 47 and 48.
  • a motor 65 mounted on the slide guide 48 is a motor 65 serving as an raising device for causing the slide guides 47 and 48 to slide by rotating a screw rod (not shown) through a speed reduction gear 64.
  • the maintenance operation can be conducted at the landing 6, thereby achieving an improvement in terms of operational efficiency. Further, the driving machine 30 and the control panel 33 can be automatically prevented from being flooded in water.
