  • Such belts and ropes are filled with resin between strands in which strands are twisted together to prevent contact between the strands, thereby extending the life.
  • Belts and ropes covered with resin are damaged due to fatigue due to bending when passing through sheaves and pulleys, wear due to relative slip between the strands, and wear due to relative slip between the sheave grooves, and the life is reached. Since these belts and ropes cannot be visually inspected for damage to the internal wires because the outer layer is covered with resin, an inspection using electrical resistance is performed as a method for inspecting the damage to the wires.
  • the resin is removed, the wire bundle and the power source are connected, current is passed, and the electrical resistance is measured. Inspect for damaged wires. That is, when the strand breaks, the total cross-sectional area of the strand bundle decreases and the resistance increases. Therefore, the damage of the strand can be inspected by measuring the electrical resistance.

  • the resin is filled between the wire bundles so as to prevent the contact between the wire bundles.
  • the surface pressure increases, the resin filled between the wire bundles is eliminated, and the wire bundles come into contact with each other.
  • the electrical resistance changes. Therefore, when inspecting the damage of the wire, there is a problem that it is difficult to make a high-precision inspection because it is impossible to distinguish whether the change in electrical resistance is due to the damage of the wire or the contact of the wire bundle. .

  • a curved surface 21 is provided on the surface of the wedge member 2 that contacts the rope 1 so as to follow the outer diameter shape of the rope 1. As shown in FIG. 2, the curved surface 21 is knurled, for example, to increase the coefficient of friction between the rope 1 and the wedge member 2 and prevent slippage.
  • other processes for example, sandblasting, may be sufficient.
  • the gripping member 3 is disposed so as to contact the butted surfaces of the two divided members, and is integrated by the screw 31 to grip the rope 1. That is, when the screw 31 is tightened and the butting surface 32 comes into contact, the position of the rope gripping surface 33 of the gripping member 3 is determined, and the collapse of the rope 1 due to excessive tightening of the screw 31 can be avoided.
  • the gripping member 3 needs to be fixed to the rope 1 with a sufficient frictional force while suppressing the collapse of the rope 1 as much as possible. Therefore, knurling or sandblasting can be applied to the rope gripping surface 33 in order to increase the friction coefficient with the rope 1.
  • the elastic member 4 is, for example, a coil spring that generates a spring force by compression.
  • the socket 5 includes a large opening 52 for inserting the wedge member 2 and a small opening 53 from which the rope 1 is drawn.
  • the rope 1 is formed by twisting strands 12 formed by twisting metal strands 11 to form a Schenkel 13 which is a strand of strands.
  • a core schenkel 14 is arranged at the center of the rope 1, and a plurality of side schenkels 15 are arranged at equal intervals in the circumferential direction of the rope.
  • an inner layer resin 16 made of polyurethane is filled, and the schenkels that are bundles of wires are not normally in contact with each other.
  • An outer layer resin 17 made of polyurethane, for example, is provided around the side schenkel 13.
  • the schenkel 13 is covered with the outer layer resin 17 and is protected from contact with other schenkels and sheaves.
  • the elastic member 4 is compressed by the wedge member 2 and the gripping member 3, and the elastic member 4 moves the wedge member 2 toward the small opening 53. Since the wedge member 2 moves to the small opening 53 along the wedge receiving surface 51, the rope 1 is clamped by the wedge member 2. When the frictional force between the wedge member 2 and the rope 1 becomes larger than the frictional force between the wedge member 2 and the wedge receiving surface 51, the wedge member 2 moves to the small opening 53 simultaneously with the rope 1, and the repulsive force due to the compression of the rope 1 and the wedge When the pressing force by the member 2 is suspended, the wedge member 2 stops.
  • the rope 1 When the rope end fixing device is connected to the hoistway wall surface, the rope 1 lifts the rope end fixing device when the rope 1 is lifted. This force tries to lift the socket 5, but when the friction coefficient between the wedge member 2 and the socket 5 is not sufficient, the wedge member 2 is lifted with respect to the socket 5. For this reason, the pressing force against the rope 1 by the wedge member 2 decreases, and the rope 1 tends to come out of the socket 5. At this time, the wedge member 2 is pressed against the small opening 53 by the gripping member 3 and the elastic member 4 so that the wedge member 2 quickly holds the rope 1, and the rope 1 is prevented from coming off to a minimum.

  • the rope 1 clamped by the wedge member 2 since the rope 1 clamped by the wedge member 2 always receives a compressive load from the wedge member 2, the inner layer resin 16 and the outer layer resin 17 are gradually deformed, and the rope diameter is reduced. In this case, the rope 1 and the wedge member 2 are displaced toward the small opening 53, and the amount of protrusion of the wedge member 2 from the small opening 53 increases. When the amount of decrease in the rope diameter is different for each wedge member 2, a difference occurs in the amount of protrusion of the wedge member 2, and the rope holding force by the wedge member 2 is reduced. Accordingly, by inspecting the position of the wedge member 2 from the window 501, the rope terminal device can be reattached at an appropriate time.
  • the amount of deflection of the elastic member 4 can be measured through the window 501 to inspect the clamping force of the wedge member 2 and the gripping force of the gripping member 3. That is, the rope 1 is held by the wedge member 2, but when the holding force by the wedge member 2 is reduced due to an abnormality such as damage to the outer layer resin 17, the rope 1 is pulled from the socket 5 toward the small opening 53. . For this reason, the amount of deflection of the elastic member 4 attached between the wedge member 2 and the gripping member 3 is reduced.
  • the amount of deflection of the elastic member 4 is inspected from the window 501, and if it is equal to or less than the predetermined amount of deflection, it is determined that the clamping force of the wedge member 2 has decreased, and the rope terminal fixing device is reattached at an appropriate time. Can be implemented.
