Definitions

  • the present invention relates to an elevator main rope elongation compensating apparatus disposed in an elevator using a synthetic fiber rope for a main rope, the elevator main rope elongation compensating apparatus maintaining an appropriate positional relationship between a car and a counterweight in response to changes in the length of the main rope due to seasonal fluctuations, etc.
  • the present invention aims to solve the above problems and an object of the present invention is to provide an elevator main rope elongation compensating apparatus capable of coping adequately with changes in the length of a main rope composed of a synthetic fiber rope.
  • an elevator main rope elongation compensating apparatus disposed in an elevator in which a main rope for suspending a car and a counterweight is composed of a synthetic fiber rope and is wound around a drive sheave of a driving machine and a deflection sheave, including a rotatable adjusting sheave displaceably disposed between the drive sheave and the deflection sheave so as to be in contact with the main rope, a length of the main rope between the drive sheave and the deflection sheave being adjusted by displacing the rotatable adjusting sheave.
  • Figure 1 is a structural diagram showing an elevator having a main rope elongation compensating apparatus according to Embodiment 1 of the present invention.
  • a driving machine 1 and a deflection sheave 2 are installed in an upper portion of a hoistway.
  • a main rope 3 composed of a synthetic fiber rope is wound around a drive sheave 1a of the driving machine 1 and the deflection sheave 2.
  • a car 4 is suspended from a first end portion of the main rope 3.
  • a counterweight 5 is suspended from a second end portion of the main rope 3.
  • a rotatable adjusting sheave 6 contacting the main rope 3 is disposed between the drive sheave 1a and the deflection sheave 2.
  • the adjusting sheave 6 is displaced by a driving force from a sheave driving machine 7 having a reduction gear so as to be guided by a guide apparatus 8 and slide linearly.
  • a length of the main rope 3 between the drive sheave 1a and the deflection sheave 2 is changed by the displacement of the adjusting sheave 6.
  • the adjusting sheave 6 is disposed on an opposite side of the main rope 3 from the drive sheave 1a and the deflection sheave 2.
  • a detector apparatus 9 for detecting changes in the length of the main rope 3 is disposed in the hoistway.
  • a detector apparatus detecting the position of a marking disposed on the main rope 3, or a detector apparatus detecting the position of the counterweight 5 when the car 4 is positioned at a predetermined floor, etc. is used for the detector apparatus 9.
  • the position of the marking or the counterweight 5 can be detected, for example, by means of an optical switch, or a mechanical micro switch, etc.
  • the sheave driving machine 7 is driven in response to a signal from the detector apparatus 9, automatically adjusting the position of the adjusting sheave 6.
  • the main rope elongation compensating apparatus includes the adjusting sheave 6, the sheave driving machine 7, the guide apparatus 8, and the detector apparatus 9.
  • FIG 2 is a perspective showing a construction of the main rope 3 from Figure 1 .
  • an inner strand layer 24 having a plurality of inner strands 22 and filler strands 23 disposed in gaps between these inner strands 22 is disposed around a core wire 21.
  • Each of the inner strands 22 is composed of a plurality of aramid fibers and an impregnating material such as a polyurethane or the like.
  • the filler strands 23 are composed of a polyamide, for example.
  • An outer strand layer 26 having a plurality of outer strands 25 is disposed around an outer circumference of the inner strand layer 24.
  • Each of the outer strands 25 is composed of a plurality of aramid fibers and an impregnating material such as a polyurethane or the like in a similar manner to the inner strands 22.
  • a friction-reducing coating layer 27 for preventing abrasion of the strands 22 and 25 due to friction among the strands 22 and 25 is disposed between the inner strand layer 24 and the outer strand layer 26.
  • a protective coating layer 28 is also disposed on an outer circumferential portion of the outer strand layer 26.
  • the synthetic fiber rope having the above construction has a high coefficient of friction compared to a steel rope and is superior in flexibility.
  • a main rope elongation compensating apparatus of this kind when expansion of the main rope 3 is detected by the detector apparatus 9, the sheave driving machine 7 is driven automatically in response to a signal from the detector apparatus 9, sliding the adjusting sheave 6 downward in Figure 1 along the guide apparatus 8. Hence, the length of the main rope 3 between the drive sheave 1a and the deflection sheave 2 is increased as indicated by the double-dotted chain lines in Figure 1 , absorbing an amount equal to the elongation over the entire main rope 3. Then, when the positional relationship between the car 4 and the counterweight 5 returns to an appropriate state, movement of the adjusting sheave 6 is stopped automatically.
  • the positional relationship between the car 4 and the counterweight 5 is maintained in an appropriate state even if expansion or contraction arises in the main rope 3 composed of the synthetic fiber rope. Furthermore, because the adjusting sheave 6 is guided by the guide apparatus 8 so as to slide linearly, the adjusting sheave 6 can be displaced stably.
  • the adjusting sheave 6 is disposed on the opposite side of the main rope 3 from the drive sheave 1a and the deflection sheave 2, when elongation arises in the main rope 3, the adjusting sheave 6 is displaced in a direction that increases the contact angle of the main rope 3 on the drive sheave 1a, preventing traction between the main rope 3 and the drive sheave 1a from being reduced due to the displacement of the adjusting sheave 6.
  • FIG 3 is a structural diagram showing an elevator having a main rope elongation compensating apparatus according to Embodiment 2 of the present invention.
  • the adjusting sheave 6 is mounted to a tip portion of a pivotable arm 11.
  • the arm 11 is pivoted about a base end portion by a sheave driving machine 12.
  • the adjusting sheave 6 is displaced by the pivoting of the arm 11.
  • the rest of the construction is similar to that of Embodiment 1.
  • a main rope elongation compensating apparatus of this kind when expansion of the main rope 3 is detected by the detector apparatus 9, the sheave driving machine 12 is driven automatically in response to a signal from the detector apparatus 9, displacing the adjusting sheave 6 downward in Figure 3 by pivoting the arm 11 counterclockwise in Figure 3 .
  • the length of the main rope 3 between the drive sheave 1a and the deflection sheave 2 is increased as indicated by the double-dotted chain lines in Figure 3 , absorbing an amount equal to the elongation over the entire main rope 3.
  • the pivoting of the arm 11 is stopped automatically.
  • the positional relationship between the car 4 and the counterweight 5 is maintained in an appropriate state even if expansion or contraction arises in the main rope 3 composed of the synthetic fiber rope.
  • the adjusting sheave 6 is displaced automatically but may be displaced manually, for example, using a ball screw or the like.
  • the adjusting sheave 6 is disposed on the opposite side of the main rope 3 from the drive sheave 1a and the deflection sheave 2, but the adjusting sheave 6 may also be disposed on the same side of the main rope 3 as the drive sheave 1a and the deflection sheave 2.
