Definitions

  • the present invention relates to a machine-roomless elevator apparatus in which a driving machine is installed inside a hoistway.
  • Patent Document 1 Japanese Patent Laid-Open No. 2001-72347
  • the present invention aims to solve the above problems and an object of the present invention is to provide an elevator apparatus that enables temperature increases in a top portion of a hoistway to be suppressed efficiently.
  • an elevator apparatus including: a driving machine that is installed inside a hoistway; a car that can be raised and lowered inside the hoistway by the driving machine; and a ventilating duct that has an upper portion air supply and exhaust opening that is positioned higher than a landing entrance of an uppermost floor inside the hoistway, and a lower portion air supply and exhaust opening that is positioned lower than the upper portion air supply and exhaust opening inside the hoistway.
  • an elevator apparatus including: a driving machine that is installed inside a hoistway; a car and a counterweight that can be raised and lowered inside the hoistway by the driving machine; and a partitioning plate that has an upper end portion that is positioned higher than a landing entrance of an uppermost floor inside the hoistway, and a lower end portion that is positioned lower than the upper end portion inside the hoistway, the partitioning plate being disposed between a hoisting zone of the car and a hoisting zone of the counterweight.
  • FIG. 1 is a structural diagram that shows part of an elevator apparatus according to Embodiment 1 of the present invention.
  • a driving machine 2 is installed in an upper portion inside a hoistway 1 (a hoistway top portion).
  • the driving machine 2 has: a drive sheave; a motor portion that rotates the drive sheave; and a brake portion that brakes rotation of the drive sheave.
  • the driving machine 2 is disposed such that a rotating shaft of the drive sheave is vertical or approximately vertical.
  • a thin hoisting machine that has a shorter axial dimension than a dimension that is perpendicular to an axial direction is used for the driving machine 2.
  • the driving machine 2 is supported by a supporting beam (not shown) that is fixed to the hoistway top portion.
  • a car 3 and a counterweight (not shown) are suspended inside the hoistway 1 by a main rope (not shown) that is wound around the drive sheave, and are raised and lowered inside the hoistway 1 by a driving force from the driving machine 2.
  • the upper portion air supply and exhaust opening 4a is positioned in the hoistway top portion and faces a side surface of the driving machine 2.
  • the lower portion air supply and exhaust opening 4b is positioned above a floor surface level of the uppermost floor inside the hoistway 1 and opens directly downward.
  • the ventilating duct 4 is bent approximately at a right angle in a vicinity of the upper portion air supply and exhaust opening 4a such that an end portion near the upper portion air supply and exhaust opening 4a of the ventilating duct 4 is horizontal and an end portion near the lower portion air supply and exhaust opening 4b is vertical.
  • An upper end portion of the ventilating duct 4 is fixed to the supporting beam that supports the driving machine 2.
  • a driving machine mount portion to which the driving machine 2 is mounted and a duct mount portion to which the ventilating duct 4 is mounted are disposed on the supporting beam.
  • Figure 3 is a graph that shows relationships between distance from a hoistway ceiling in Figure 1 and temperature, the broken line representing a case in which ventilation that uses the ventilating duct 4 is not performed and the solid line representing a case in which ventilation that uses the ventilating duct 4 is performed. If ventilation is not performed, the temperature in the top portion of the hoistway is highest at the ceiling portion and decreases rapidly in the vicinity of the landing entrance 5 of the uppermost floor, as indicated by the broken line in Figure 3 . In contrast, if ventilation is performed, the temperature in the top portion of the hoistway can be reduced, as indicated by the solid line in Figure 3 . Furthermore, since ventilation between a landing and a vicinity of the landing entrance 5 is easily performed by opening and closing the door, temperature increases are only slight even if warm air from the top portion of the hoistway is conveyed there by the ventilating duct 4.
  • aperture area of the upper portion air supply and exhaust opening 4a of the ventilating duct 4 is sufficiently smaller than a vertical footprint area of the car 3, airflow velocity inside the ventilating duct 4 will be sufficiently faster than a traveling speed of the car 3 if flow channels of air that might flow outside the ventilating duct 4 due to ascent and descent of the car 3 are blocked as much as possible. If, for example, the vertical footprint area of the car 3 is ten times the aperture area of the upper portion air supply and exhaust opening 4a then, ignoring loss, the airflow velocity inside the ventilating duct 4 will be ten times the traveling speed of the car 3.
  • FIG. 4 is a structural diagram that shows part of an elevator apparatus according to Embodiment 2 of the present invention.
  • a control apparatus 6 that controls a driving machine 2 is installed inside a hoistway 1.
  • the control apparatus 6 is fixed to a hoistway wall so as to be approximately equal in height to an uppermost floor.
  • a cooling fan 7 is disposed on the control apparatus 6.
  • a lower portion air supply and exhaust opening 4b is disposed so as to face an upper surface of the control apparatus 6.
  • a plurality of electrical wires (not shown) that connect the control apparatus 6 and the driving machine 2 are inserted through and accommodated in a ventilating duct 4.
  • the ventilating duct 4 also serves as a wiring duct. The rest of the configuration is similar to that of Embodiment 1.
  • the control apparatus 6 is disposed so as to face the lower portion air supply and exhaust opening 4b, ventilation of the top portion of the hoistway can be performed through the ventilating duct 4 by driving the cooling fan 7 of the control apparatus 6 even when the car 3 has stopped or is being raised and lowered at lower floors, etc., enabling temperature increases in the top portion of the hoistway to be suppressed efficiently.
  • the ventilating duct 4 also serves as a wiring duct, costs can be reduced and effective utilization of space can be achieved.
  • FIG. 5 is a structural diagram that shows part of an elevator apparatus according to Embodiment 3 of the present invention.
  • a driving machine 12 is installed in an upper portion inside a hoistway 11 (a hoistway top portion).
  • the driving machine 12 has: a drive sheave; a motor portion that rotates the drive sheave; and a brake portion that brakes rotation of the drive sheave.
  • the driving machine 12 is disposed such that a rotating shaft of the drive sheave is horizontal.
  • the driving machine 12 is supported by a supporting beam (not shown) that is fixed to the hoistway top portion.
  • a deflection sheave 13 is disposed in a vicinity of the driving machine 12.
  • a main rope 14 is wound around the drive sheave and the deflection sheave 13.
  • a car 15 and a counterweight 16 are suspended inside the hoistway 11 by the main rope 14, and are raised and lowered inside the hoistway 11 by a driving force from the driving machine 12.
  • the upper end portion 18a is disposed between the driving machine 12 and the deflection sheave 13.
  • the lower end portion 18b is positioned higher than a floor surface level of the uppermost floor.
  • the partitioning plate 18 is fixed to at least one hoistway wall, or to the supporting beam, or to a combination thereof.
  • Temperature increases in the vicinity of the hoistway top portion are thereby suppressed efficiently, ensuring a temperature safety margin for machinery that is disposed in the hoistway top portion such as the driving machine 2, etc., enabling service life of the machinery to be extended.
  • the air current can also be regulated by the partitioning plate 18, enabling hoisting resistance of the car 15 to be reduced.
  • FIG. 6 is a structural diagram that shows part of an elevator apparatus according to Embodiment 4 of the present invention.
  • a lower end portion 18b of a partitioning plate 18 is positioned lower than that of Embodiment 3.
  • a vertical dimension of the partitioning plate 18 is longer than that of Embodiment 3.
  • the lower end portion 18b is positioned in a vicinity of a floor that is two floors lower than an uppermost floor. The rest of the configuration is similar to that of Embodiment 3.
  • FIG. 7 is a structural diagram that shows part of an elevator apparatus according to Embodiment 5 of the present invention.
  • a ventilating duct 4 similar to that of Embodiment 1 is installed in an upper portion inside a hoistway 1.
  • a cooling fan 21 is disposed inside the ventilating duct 4.
  • a temperature detector 22 for detecting hoistway top portion temperature is disposed on a ceiling portion of the hoistway 1. Detection signals from the temperature detector 22 are input into the control apparatus 17.
  • the control apparatus 17 detects the hoistway top portion temperature based on the signals from the temperature detector 22. If the hoistway top portion temperature reaches a preset temperature, the control apparatus 17 moves the car 15 to an upper floor to perform a ventilation operation by raising and lowering the car 15 and the counterweight 16. If the car 15 cannot be moved to an upper floor, or if the car 15 must be stopped, the control apparatus 17 drives the cooling fan 21 to ventilate the hoistway top portion forcibly.
  • the rest of the configuration is similar to that of Embodiment 3.
  • the driving machine 2 or 12 is disposed in the hoistway top portion, but a driving machine may also be disposed in another position inside the hoistway such as a hoistway floor portion, for example. In that case, the hoistway top portion is still ventilated and temperature increases in machinery that is disposed in the hoistway top portion can be suppressed.
  • the driving machine may also be a long, slender hoisting machine in which an axial dimension is longer than a dimension that is perpendicular to an axial direction, enabling similar effects to be achieved.
  • a single ventilating duct 4 was used, but a plurality of ventilating ducts may also be used.
  • a single upper portion air supply and exhaust opening 4a was disposed on a single ventilating duct 4, but a ventilating duct that has a plurality of upper portion air supply and exhaust openings may also be used. Similarly, a ventilating duct that has a plurality of lower portion air supply and exhaust openings may also be used. If the upper portion air supply and exhaust opening of the ventilating duct is made to face the driving machine, extension of service life of a comparatively weak encoder (a rotation detector that generates signals that correspond to rotation of the motor portion) that is disposed on the driving machine can be achieved by making the upper portion air supply and exhaust opening face the encoder.
  • a comparatively weak encoder a rotation detector that generates signals that correspond to rotation of the motor portion
