Preferred embodiments of the present invention will be described below with reference to the drawings.
Embodiment 1 FIG.
1 is a schematic configuration diagram showing an elevator apparatus according to Embodiment 1 of the present invention. In the figure, a driving device 3 having a driving sheave 2 and a rotatable deflecting wheel 4 are arranged at the upper part of the hoistway 1. A plurality of belt-like main ropes 5 that are elevator ropes are wound around the drive sheave 2 and the deflecting wheel 4. Each main rope 5 has first and second end portions 5a and 5b. The first and second end portions 5 a and 5 b are connected to a support beam 6 fixed to the upper part in the hoistway 1.
The car 7 and the counterweight 8 are suspended in the hoistway 1 by the main rope 5 and are raised and lowered by the driving force of the driving device 3. The car 7 is provided with a car suspension wheel 9 around which the main rope 5 is wound. The counterweight 8 is provided with a counterweight suspension vehicle 10 around which the main rope 5 is wound.
FIG. 2 is an explanatory view showing the positional relationship between the drive sheave 2 and the car suspension 9 in FIG. The drive sheave 2 and the car suspension wheel 9 are arranged so that their rotation axes extend along a direction perpendicular to each other in the vertical projection plane. Thereby, the main rope 5 is twisted by 90 ° between the drive sheave 2 and the car suspension wheel 9. In other words, the driving device 3, the car 7 and the counterweight 8 are arranged so that the main rope 5 is twisted.
3 is a cross-sectional view of the main rope 5 of FIG. 1, and FIG. 4 is a cross-sectional view taken along line IV-IV of FIG. In the figure, the main rope 5 has a belt-shaped rope body 11. The rope main body 11 includes seven cords 12 that are spaced apart from each other in the width direction of the rope main body 11 and a resin cover 13 that covers and integrates the cord 12. Each lasso 12 has a plurality of steel strands 14. The strands 14 are twisted in parallel with each other (see JIS G 3525 12.2b). The cross-sectional structure of the lasso 12 is preferably a Warrington type defined in JIS G 3525.
The covering 13 is made of, for example, a thermoplastic ether-based polyurethane resin. An adhesive 15 is applied to at least the outer periphery of each lasso 12 in order to integrate the lasso 12 with the covering 13. That is, the lasso 12 and the covering 13 are bonded to each other via the adhesive 15.
A plurality of gaps 13 a extending along the longitudinal direction of the rope body 11 are provided in the longitudinal direction of the rope body 11 at intervals between the adjacent strands 12 of the covering body 13. The gap 13a penetrates the rope body 11 in the thickness direction. At both ends in the longitudinal direction of each gap 13a, a stress relaxation portion 13b having a rounded cross-sectional shape is provided. Here, the cross section of the stress relaxation portion 13b is substantially circular.
Between the gaps 13 a adjacent to each other in the longitudinal direction of the rope body 11, a coupling portion 13 c that is not provided with a gap 13 a is formed. Further, the gaps 13 a adjacent to each other in the width direction of the rope main body 11 (left and right direction in FIG. 4) are arranged so as to be shifted from each other by a half pitch in the longitudinal direction of the rope main body 11.
In such an elevator apparatus, the main rope 5 is twisted between the driving sheave 2 and the car suspension wheel 9 and the counterweight suspension wheel 10, so the geometry of the rope 12 depends on the position of the rope body 11 in the width direction. Therefore, the load on the lasso 12 varies depending on the position of the rope body 11 in the width direction.
When a difference occurs in the tension of the strand 12 due to such a difference in burden load, a shearing force acts on a portion between the adjacent strands 12 of the covering 13. And there is a possibility that peeling of the adhesive 15, breakage of the covering 13, and fatigue breakage of the strand 14 of the strand 12 having a large burden load.
On the other hand, in this Embodiment 1, since many gap | intervals 13a are provided in the covering 13, the restraint force of the lasso 12 by the covering 13 is reduced, and the lasso in the width direction of the rope main body 11 is reduced. Twelve movements are allowed to some extent.
Therefore, peeling of the adhesive 15, breakage of the covering 13, and fatigue breakage of the wire 14 are suppressed, and a stable strength can be ensured and a long life can be achieved. That is, since damage does not concentrate on the specific rope 12, the life of the main rope 5 as a whole can be extended.
Further, the binding force of the lasso 12 by the covering body 13 can be easily set by the interval between the gaps 13a adjacent to each other in the longitudinal direction of the rope body 11, that is, the length of the coupling portion 13c.
Furthermore, since the stress relaxation portion 13b is provided in the gap 13a, the stress concentration at the both ends in the longitudinal direction of the gap 13a is relaxed, and the generation and propagation of cracks due to the stress concentration can be suppressed.
Furthermore, the gaps 13a adjacent to each other in the width direction of the rope body 11 are arranged so as to be shifted from each other by a half pitch in the longitudinal direction of the rope body 11, so that the coupling portion 13c is also shifted from each other in the longitudinal direction of the rope body 11. It is arrange | positioned and an intensity | strength can be equalized about the longitudinal direction of the rope main body 11. FIG.
Embodiment 2. FIG.
5 is a cross-sectional view of an elevator rope according to Embodiment 2 of the present invention. In the figure, high-strength fibers 16 as a reinforcing material are evenly mixed in the covering body 13. As the high-strength fiber 16, for example, an aramid resin fiber or glass fiber is used. The high-strength fibers 16 are mixed with the covering 13 as single fibers or as an aggregate of a plurality of single fibers. Other configurations are the same as those in the first embodiment.
According to such a structure, the intensity | strength of the coating body 13 can be raised and the strength reduction of the coating body 13 by providing the clearance gap 13a can be prevented. Moreover, since the high-strength fiber 16 as a reinforcing material is used, the tensile strength of the covering 13 is increased, but the reinforcing effect in the shearing direction and the compression direction is low, and the movement of the lasso 12 is prevented from being suppressed. Is done.
Embodiment 3 FIG.
6 is a sectional view of an elevator rope according to Embodiment 3 of the present invention, and FIG. 7 is a sectional view taken along the line VII-VII in FIG. In the figure, a belt-shaped rope body 21 includes seven strands 22 arranged at intervals in the width direction of the rope body 21, a resin covering 13 that covers and integrates the strands 22, And a woven fabric body 23 embedded in the covering body 13 so as to surround the lasso 22.
Each of the strands 22 includes a resin core member 24 extending along the longitudinal direction of the rope body 21 and three unit strands 25 arranged around the core member 24 and twisted around the core member 24. And each. Each unit rope 25 has a plurality of steel strands 26. The strands 26 are twisted in parallel with each other.
As the material of the core material 24, for example, a thermoplastic resin such as polypropylene resin, polyethylene resin or vinyl, or a high-strength synthetic resin fiber such as aramid fiber or polypropylene fiber can be used.
An adhesive (not shown) is applied to at least the outer peripheral portion of each unit rope 25 so as to be integrated with the covering 13.
The woven fabric body 23 is obtained by weaving high-strength fibers such as aramid resin fibers or glass fibers into a cloth shape. The high-strength fibers are woven as a single fiber or as an aggregate of a plurality of single fibers. The woven fabric 23 may be disposed only between the adjacent cords 22.
The covering body 13 is provided with a plurality of gaps 13a. In the third embodiment, the gaps 13 a adjacent to each other in the width direction of the rope body 11 are arranged side by side at the same position in the longitudinal direction of the rope body 21.
According to such a configuration, since the strand 22 is composed of the core member 24 and the three unit strands 25, the thinner strands 26 can be used, and the diameter of the sheave to be applied can be reduced. Can do.
Further, since the woven fabric body 23 is embedded in the covering body 13, the strength of the covering body 13 can be increased, and the strength reduction of the covering body 13 due to the provision of the gap 13a can be prevented. Moreover, since the fabric 23 as the reinforcing material is used, the tensile strength of the covering 13 is increased, but the reinforcing effect in the shearing direction and the compressing direction is low, and the movement of the lasso 22 is prevented from being suppressed. The
Furthermore, since the gap 13a is arranged side by side at the same position in the longitudinal direction of the rope body 21, the fabric 23 is not finely divided by the gap 13a, and the reinforcing effect of the fabric 23 can be enhanced.
In the above example, the gap 13a penetrating the rope main bodies 11 and 21 is shown. However, a hole opened only on one side of the rope main body or a hollow gap having no opening may be used.
In the above example, the gap 13a is a gap, but a substance made of a material different from that of the covering may be filled in the gap. However, as the material filled in the gap, those that prevent the movement of the lasso are not preferable.
Furthermore, arrangement | positioning of the strand and core material which comprise a lasso is not limited to FIG.3 and FIG.6, A various change is possible.
Furthermore, although the 2: 1 roping type elevator apparatus is shown in the above example, the elevator rope of the present invention can be applied to other types of elevator apparatuses such as a 1: 1 roping system. However, when applied to an elevator apparatus in which the rope body is twisted, an especially excellent effect is obtained.
