Definitions

  • the present invention relates to a synthetic fiber rope which is coiled around a sheave to suspend a vertically-movable member and which is actuated by means of rotation of a sheave to vertically move the vertically-movable member.
  • a wire rope that is, a steel rope, has hitherto been used as a main cable for suspending an elevator car.
  • a rescue operation is performed for rescuing passengers confined in the car after determination of a location in a shaft where the car has accidentally stopped.
  • indices corresponding to car positions in the shaft are marked on the main cable in advance.
  • the position of an accidentally-stopped car is specified by way of an index assigned to the main cable when accidental stoppage of an elevator system has arisen. For instance, a car is located in a position between the fifth and sixth floors, and then passengers are rescued.
  • the present invention aims at obtaining a synthetic fiber rope for use with an elevator, in which indices attached to a main cable can be readily identified even after the main cable has been installed.
  • an outer sheath layer is formed from flexible synthetic resin so as to cover a plurality of strands constituting an outer circumference of a main cable formed from a synthetic fiber rope for use with an elevator, and adjacent segments of predetermined lengths are formed in the outer sheath layer so as to differ in color from each other.
  • the position of a car in a shaft is assigned to one of the colored segments in the outer sheath layer beforehand.
  • the outer sheath layer is made of synthetic resin, the layer can be readily colored during a manufacturing process. Even after an elevator system has been used for a long period of time, there can be prevented difficulty in identifying indices, which would otherwise be caused by wear of the outer sheath layer.
  • the outer sheath layer is made in a color different from that of the strands, thereby facilitating and enabling appropriate determination of the wear state of the outer sheath layer. Because of this, the efficiency of maintenance and inspection of the main cable of the elevator system can be improved.
  • the present invention may also be embodied as a synthetic fiber rope for use with an elevator, comprising: rope cores; a plurality of strands provided along an outer circumference of the rope cores, each strand being made by means of twisting a plurality of flexible synthetic fibers; and an outer sheath layer which is made of flexible synthetic resin, and which is formed along an outer circumference of the strands, wherein a coating layer differing in color from the outer sheath layer is formed on the surfaces of the strands.
  • reference numeral 1 designates rope cores provided in the center of a transverse cross section of a synthetic fiber rope.
  • Each of the rope cores is made from a plurality of strands, each strand being made by braiding a plurality of synthetic fibers.
  • Reference numeral 2 designates a plurality of strands provided along an outer circumference of the rope cores 1, and each of the strands 2 is made by braiding a plurality of flexible synthetic fibers.
  • Segments of predetermined lengths which differ in colors from these of other adjacent segments are formed even in other longitudinal locations in the outer sheath layer 3.
  • the outer sheath layer 3 is formed in a color different from that of the strands 2.
  • This structure prevents occurrence of difficulty in identifying indices, which would otherwise be caused by stains when an elevator has been used for a long period of time or a like reason. Consequently, there can be appropriately addressed an operation for rescuing passengers in an accidentally-stopped elevator car, thereby speeding the rescue operation.
  • the colored segments enable easy determination of the extent of elongation of a synthetic fiber rope due to aging.
  • the efficiency of maintenance and inspection of the main cable of the elevator system can be improved.
  • the outer sheath layer 3 is formed in a color different from that of the strands 2, a wear state of the outer sheath 3 can be readily and appropriately determined. For this reason, the efficiency of maintenance and inspection of the main cable of the elevator system can be improved.
  • a coating layer is formed on the surface of each of the strands 2 by means of impregnation of paint.
  • the paint of the strands 2 is transferred to the sheave (not shown) around which the synthetic fiber rope is wound.
  • Such a structure enables appropriate determination of wear of the outer sheath layer 3 at the time of periodic inspection of an elevator system, by means of merely observing whether or not the paint of the strands 2 has been transferred to the sheave, without involvement of visual inspection of the entire synthetic fiber rope so as to determine whether or not the strands 2 become exposed in any location of the rope.
  • maintenance and inspection of the elevator system can be improved.
  • the coating layer to be formed on the surface of the strands 2 is preferably a layer of fluorescent paint. If a layer of fluorescent paint is formed on the surfaces of strands, the paint is easily acknowledged by an inspection worker by means of a fluorescent characteristic. If the paint of the coating layer has been transferred onto a sheave, the paint can be readily detected. Moreover, the fluorescent paint that has been transferred onto the sheave is less prone to disappear. Even if a slight delay has arisen in the time of routine inspection, the paint can be detected readily.
  • the outer sheath layer is made in a color different from that of the strands, thereby facilitating and enabling appropriate determination of the wear state of the outer sheath layer.
  • the rope according to the invention is useful as a synthetic fiber rope for use with an elevator which is wound around a sheave and suspends a vertically-movable member and is suitable for actuation by means of rotation of the sheave, to thereby vertically move the vertically-movable member.
