Definitions

  • This invention relates to a so-called machine-room-less type elevator apparatus in which no dedicated machine room for installing the driving machine and control panel is provided in the upper portion of the hoistway.
  • 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.
  • This invention has been made with a view toward solving the above problems. It is accordingly an object of this invention to provide an elevator apparatus in which interference between car and driving machine can be prevented, and in which maintenance can be conducted with ease.
  • an elevator apparatus comprising: a hoistway having a pit at the bottom; a car that ascends and descends in the hoistway; a main rope for suspending the car in the hoistway; and a driving machine for raising and lowering through the main rope, wherein an installation space adjacent to the pit is provided under the floor of a landing of a lowermost floor, the driving machine being arranged in the installation space.
  • Fig. 1 is a plan view of an elevator apparatus according to Embodiment 1 of this invention
  • 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.
  • the partition 13 serving as a fireproof wall is provided between the installation space 7 and the pit 1a, even if a fire were to be caused in the driving machine 8, intrusion of flames into the hoistway 1 can be prevented. Further, since the partition 13 also serves as a soundproof wall, the noise of the driving machine 8 is prevented from being transmitted to the interior of the car 4 through the hoistway 1.
  • 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.
