Definitions

  • the present invention relates to an elevator apparatus in which a drive device (hoisting machine) for raising and lowering a car and a counterweight is arranged in a hoistway (so-called machine room-less elevator apparatus).
  • the present invention has been made in view of the above-mentioned problem, and therefore it is an obj ect of the present invention to provide an elevator apparatus capable of achieving a reduction in manufacturing cost and space saving.
  • An elevator apparatus includes: a car and a counterweight that are capable of being raised and lowered in a hoistway; guide rails arranged in the hoistway, for guiding the car and the counterweight respectively; a support structure having a support column extending upwardly from a bottom portion of the hoistway, the support structure being arranged in the hoistway separately from the guide rails; a drive device having a drive sheave and supported by the support structure; and a main rope wound around the drive sheave, for suspending the car and the counterweight.
  • Fig. 1 is a perspective view showing an elevator apparatus according to Embodiment 1 of the present invention.
  • a pair of car guide rails 2, 3, and a pair of counterweight guide rails 4, 5 are arranged in a hoistway 1.
  • a car 6 is raised and lowered in the hoistway 1 while being guided by the car guide rails 2, 3, and a counterweight 7 is raised and lowered in the hoistway 1 while being guided by the counterweight guide rails 4, 5.
  • the car 6 and the counterweight 7 are arranged adjacent to each other with respect to the width direction of the car 6 within the vertical projection plane of the hoistway 1. Further, as seen in the vertical projection of the hoistway 1, the line connecting between the car guide rails 2, 3 is perpendicular to the line connecting between the counterweight guide rails 4, 5.
  • support structures 8, 9 Arranged on one and the other side portions of the hoistway 1 are support structures 8, 9 for supporting the loads of the car 6 and counterweight 7, respectively.
  • the support structures 8, 9 are arranged separately and independently from the car guide rails 2, 3 and the counterweight guide rails 4, 5, respectively. It should be noted that a die steel member used for construction is used as each of the support structures 8, 9.

  • This allows each of the car guide rails 2, 3 and counterweight guide rails 4, 5 to be reduced in size, making it possible to achieve a reduction in the manufacturing cost of each of the car guide rails 2, 3 and the counterweight guide rails 4, 5.
  • the manufacturing cost of the support structures 8, 9, which are used solely for the purpose of supporting load, is low, and the increase in cost attributable to the manufacturing cost of the support structures 8, 9 is small relative to the decrease in cost attributable to the reduced sizes of the car guide rails 2, 3 and counterweight guide rails 4, 5, thereby achieving a reduction in the manufacturing cost of the elevator apparatus as a whole.
  • the horizontal sectional area of the hoistway 1 can be made smaller by adjusting the arrangement and horizontal sectional configuration of each of the support structures 8, 9, making it possible to achieve saving of space in the elevator apparatus.
  • the first end portion 17a of each main rope 17 is connected to the support structure 8, and the second end portion 17b of each main rope 17 is connected to the support structure 9, whereby the loads of the car 6 and counterweight 7 can be supported by the support structures 8, 9, respectively. Accordingly, in the same manner as described above, the manufacturing cost of the elevator apparatus can be reduced, and space saving can be achieved for the elevator apparatus.
  • each of the support structures 8, 9 an inexpensive steel member used for construction is used as each of the support structures 8, 9, thus enabling a further reduction in the manufacturing cost of the support structures 8, 9.
  • the present invention is applied to an elevator apparatus of a type (2:1 roping) in which the car 6 and the counterweight 7 are suspended by winding the main ropes 17 around the car suspension sheaves 18 and the counterweight suspension sheave 19, respectively
  • the present invention is also applicable to an elevator apparatus of a type (1: 1 roping) in which the car 6 and the counterweight 7 are suspended by connecting the first end portion 17a of each main rope 17 to the car 6 and connecting the second end portion 17b of each main rope 17 to the counterweight 7, respectively.
  • the number of support columns 10 is two, the number of support columns 10 may be three or more. In this case, the support columns 10 are arranged at a spacing from each other in the depth direction of the car 6.
  • the number of support columns 12 is two, the number of support columns 12 may be three or more.
  • the support columns 12 are arranged at a spacing from each other in the depth direction of the car 6 so as to avoid interference with the counterweight guide rails 4, 5 and the counterweight 7.
  • Fig. 2 is a perspective view showing an elevator apparatus according to Embodiment 2 of the present invention.
  • a car 6 and a counterweight 7 are arranged adjacent to each other with respect to the depth direction of the car 6 as seen in the vertical projection plane of a hoistway 1. Further, as seen in the vertical projection of the hoistway 1, the line connecting between car guide rails 2, 3 is parallel to the line connecting between counterweight guide rails 4, 5.
