Definitions
- the present invention relates to a rope used for an elevator or a cargo handling machine.
- the ride and the counterweight are connected by a rope, and the rope is driven by the frictional force generated between the rope wound around the sheave of the hoist and the drive ship.
- a port on which a load is suspended is wound on a winding drum and driven.
- the ropes used in conventional machines of this type are composed of a fiber rope impregnated with lubricating oil at the center, and a plurality of twisted steel strands around the core. It is a combined structure.
- this rope is used by wrapping it around a small diameter chip or pulley, the life of the rope becomes extremely short due to fatigue and wear of the wire due to bending.
- the coefficient of friction with the chip is small, it is difficult to secure the driving frictional force as the diameter of the chip becomes smaller.
- the diameter of the sheave driven by friction is 40 times or more the rope diameter. That is, the drive torque is increased due to the large diameter of the sieve, and the size of the drive device is also increased.

- Japanese Patent Application Laid-Open No. 3-82883 proposes a rope in which a lubricating protective layer is provided on a wire which is close to each other, which is further twisted to further cover the outside thereof. Disclosure of the invention
- the strength member since the strength member has a smaller longitudinal elastic coefficient than the conventional wire port material, the longitudinal rigidity of the rope is reduced. For this reason, when the rope length is long, fluffy vibration of the car is likely to occur. In addition, it is an organic material, has low heat resistance, and tends to deteriorate over time. In addition, if the coil is wound around a small-diameter sieve and repeatedly bent, wear occurs between the wires and the life is shortened due to fatigue due to repeated stress. Further, the friction coefficient between the chip and the chip is so small that a slip occurs, so that a large driving force cannot be transmitted. There were problems such as.
- the present invention solves these conventional drawbacks and provides a soft, appropriate friction coefficient and long-life cap.
- the rope according to the present invention has a first coated structure in which a first structure formed by twisting metal strands is covered with a covering material as a core, and a metal strand is twisted around the core.
- a plurality of second covering structures obtained by covering the constituted second structure with a covering material are arranged and twisted, and further, a plurality of the second covering structures arranged around the first covering structure are arranged around the first covering structure.
- a third covering material for covering the periphery of the second covering structure was arranged, and the second covering material and the third covering material were joined.
- joining is interpreted to include bonding by an adhesive, fusion of two substances by heating, and bonding by chemical treatment.
- the structure or the first and second structures are formed by twisting metal strands, it is possible to form a rope having high rigidity and little aging. Since the wires are covered with a wire, the wires do not directly contact or slip, and a long-life mouth opening with excellent wear resistance can be provided.

- pulleys 5a and 5b for receiving ropes 10 are provided at the lower part of the car 1 that lifts passengers or luggage, and hangs when the car 1 is loaded with approximately 1/2 of the rated load.
- a pulley 5 e for receiving the rope 10 is provided above the counterweight 2.
- Pulleys 5c and 5d for receiving the rope 10 are provided at the top of the hoistway 7, and a driving device 3 having a sieve 3a is provided at the bottom.
- the rope 10 according to the present invention passes from a rope receiver 6a provided at the top of the hoistway to pulleys 5a and 5b under the car and a pulley 5c at the top, and to the ship 3a of the driving device 3. It is rolled up. It then passes through the top pulley 5d, the counterweight pulley 5e, and ends at the top rope receiver 6b.
- the rope 10 according to the present invention is flexible and has a large coefficient of friction between the coating and the sheave 3a, long life and reliable driving force transmission is possible even with a small sheave diameter.
- a conventional sieve diameter of 13 to 1/2 can be realized.
- the driving torque required for the driving device is also 1/3 to 1/2, so that the driving device can be significantly reduced in size.
- the pulleys at the bottom of the car, at the top of the counterweight and at the top of the hoistway also have small diameters. Distance from the shaft to the shaft pit).
- 1 2 is a first covering structure disposed at the center of the rope
- 13 is a plurality of second covering structures disposed around the first covering structure 12
- a covering 11 outer layer covering
- the diameter is 1/100 to 1/15 of the rope diameter before coating, and the material is made of high-strength steel strands.
- a coating structure inner layer coating is applied to the coating structure.
- the covering material (inner layer) of the covering structures 12 and 13 is made of an organic material that has adhesiveness to the strands and has appropriate elasticity (thermoplastic).
- the covering material (outer layer) of the covering rope is A (thermoplastic) organic material with an appropriate friction coefficient and abrasion resistance.
- the rope 10 Since the rope 10 has a plurality of second covering structures 13 twisted around the center first covering structure 12, when the covering mouth 10 is repeatedly bent, each covering structure Since the radii of curvature are slightly different between the bodies 12 and 13, they slip mutually. In addition, when tension is applied to the coating port, the coating structure is twisted, so that a pressing force acts between the coating structures and the rope is wound around the sheave or pulley. A pressing force acts in the radial direction of the rope. Thus, under actual use conditions, surface pressure acts on each other between the rope covering structures, and mutual sliding occurs.
- the covering structures 12 and 13 have no covering, the wires come into direct contact with each other and slip, resulting in wire wear.
- the life of the rope is significantly shortened by reducing the diameter of the wire to realize the flexibility of the rope.
- the covering of the covering structures 12 and 13 prevents direct contact of the wires between the structures. That is, since the covering material enters between the strands of the structural body and the strands of the adjacent structural body, there is no direct contact between these strands, and the abrasion of the strands can be suppressed.
- surface pressure and relative slip occur between the coatings of adjacent structures, and the elasticity of the coating material reduces the surface pressure and relative slip, resulting in wear resistance. Greatly improve the performance.
- the coating on the structure has the effect of alleviating the surface pressure acting between the wires of the adjacent structures. To increase this effect, it is desired to increase the coating thickness.
- the coating thickness is unnecessarily thick, the area ratio of the strength member to the cross-sectional area of the structure becomes small. This means that the ratio of the strength member occupying the cross-sectional area of the rope formed by twisting this structure is reduced, and a rope having a wide cross-sectional area is obtained with the same strength.
- the coating thickness should be as thin as possible to minimize the surface pressure between wires and relative slippage. By the way, 0.2 ⁇ 0.5 ⁇ is appropriate.
- a gap 6 is provided between adjacent structures, and the covering material is formed between the covering structures when forming the outer layer covering.
- the structure is easy to penetrate easily. As a result, not only the contact area of the outer coating 11 with the second coating structure 13 but also the contact area of the first coating structure 12 with the outer coating 11 is increased, and the inner coating and the outer coating are bonded or fused. Strength is improved.
- the outer layer coating transmits the driving force by frictional force between the outer layer coating and the sheave. This means that the coating material must be worn, and the coating material used for the outer layer must have appropriate hardness and thickness in order to improve the wear resistance.
- FIG. 3 is a diagram showing a specific structure of the covering structure 12 or 13.
- a covering structure 20 is obtained by forming a structure 22 by twisting a plurality of strands 21 and covering the outside with a covering 23.
- the diameter of the strand 21 is as described above. It should be 1/15 to 1/100 of the mouth diameter before coating the outer layer.
- the structure of the structure is (1 + 6 + 12) (two-layer winding) and 19 strands are arranged in parallel. With this structure, the contact between the wires becomes line contact, and the contact pressure between the wires is less than the point contact against the longitudinal load and the radial load acting on the rope. Is performed.
- the covering 23 When applying the covering 23 to the structure 22 in which the strands 21 are twisted, wash the structure 22 with a cleaning agent, apply adhesive, and form the covering material 23, or use a method suitable for the strand. The surface treatment is applied, the coating is molded, and the wire surface is chemically bonded to the coating. For example, there is a method in which the wire is brassed, a coating material containing sulfur is formed on the structure 22, and the plating component on the wire surface and the coating material component are chemically bonded by vulcanization.
- the wires located on the outer layer of the structure 22 are adhered to the covering and are restrained, but the wires located inside are not restrained from moving. This means that the resistance is small even when bent to a small radius of curvature, and a flexible rope can be realized. Even in this case, the wires are in direct contact with each other but are arranged in parallel. The contact area is large, the surface pressure is small, and the wire diameter is small. Since it is minute, a long life can be ensured.
- FIG. 4 shows another embodiment of the covering structure 12 or 13.
- the same symbols indicate the same parts.
- a large number of strands may be required due to the small diameter of the strands.
- the structure of such a structure is shown.
- the structure is (1 + 6 + 12 + 18) (three-layer winding) and 37 strands are twisted together Is shown. As the number of strands increases, it becomes difficult to twist the strands at the same pitch as shown in Fig.3.
- This figure shows a case where the twisting pitch of the strands of each layer is shifted little by little so that the cross section can easily maintain a circular shape.
- the strands are parallel and the intersection angle of the strands is zero, but in this embodiment, the twist angle is slightly shifted in each layer, so that the intersection angle cannot be zero.
- the intersection angle of the strands is small, and the contact length between the strands in the structure can be lengthened and the wear resistance of the strands can be improved. is there.
- the structure can be maintained while maintaining a substantially circular cross-sectional shape, and the wear resistance is improved. This good manufacturability has the effect of reducing the cost of the finished rope.
- Figure 5 shows the implementation of the coated structure 30 when more strands need to be twisted.
- a central structure 35 consisting of a plurality of twisted strands 31 is centered, and seven surrounding structures 34 of the same structure are arranged around it.
- the whole structure 32 is formed by twisting and twisting, and a coating 33 is applied to the outer periphery of the whole structure 32 to form a coating structure 30. That is, the entire structure 32 is formed by twisting seven structures 22 shown in FIG. 3, and the outer surface thereof is covered.
- the embodiment shows a case where seven of the structures 22 shown in FIG. 3 are twisted, the present invention is not limited to this structure.
- the wires are in direct contact between the adjacent surrounding structure 34 and the central structure 35, so that the wire is more abrasion resistant than the above-mentioned structure (Figs. 3 and 4). Although it is inferior, it is a structure that is suitable for the requirements of flexible and high-strength ropes. Further, even if the wires are in direct contact between the surrounding structures 34, the distance from the center of the central structure 35 is short, so that the relative sliding distance between the wires is short and the wear is small. Therefore, this structure is preferably applied to the core structure 12 having a short distance from the center of the rope.
- FIGS. 6 and 10 show a structure obtained by twisting seven covering structures 20 covering the structure 22 of FIG. That is, the single coated structure 41 is twisted to form a structure 42, and a coating 43 is applied to the outside of the structure 42 to form an entire coated structure 40. By doing so, wire contact between adjacent single coated structures 41 is eliminated, and the wear resistance of the wire is significantly improved. On the other hand, the ratio of the strength member to the cross-sectional area of the covering and the rope cross-sectional area of the covering structure 41 decreases, and the strength per unit cross-sectional area decreases. For this reason, the coating thickness should be as small as possible to reduce the surface pressure and relative slip between wires, and should be as thin as possible. This structure is selected based on the strength, dimensions and life of the coated rope.
- FIG. 7 and 11 show another embodiment of the rope structure. Basically the same as the embodiment of FIG. 2, except that eight covering structures 13 are arranged around the core covering structure 12 and twisted, and the covering 11 is applied to the outside. Structure.
- the core and surrounding covering structures 12, 13 are similar to the covering structure of FIG.
- FIG. 8 shows still another embodiment, in which a single coated structure 51 is twisted.
- a coating 53 is applied to the structure 52 thus formed to form a rope as a whole coating structure 50.
- the rope with this structure has less design restrictions than the above-mentioned rope, and the degree of freedom in design is expanded.
- the single-coated structure serving as the core and the single-coated structure disposed on the outer periphery thereof
- FIG. 12 shows still another embodiment. Basically, it is the same as the embodiment of FIG. 7, except that a core covering structure 12 is formed by twisting a strand 21 around a core steel 24. As a result, it is possible to realize a covering structure having a desired large diameter without extremely increasing the number of wires.
- the force is transmitted to the outer layer coating, the inner layer coating structure (strength member), and between the inner layer coating and the outer layer coating, Alternatively, the force is transmitted without slipping between the inner coating and the structure, and the car can be driven.
- the wire is subjected to surface treatment, and a chemical reaction occurs between the components of the covering material that covers the outside of the wire and the components on the surface of the wire.
- a chemical reaction occurs between the components of the covering material that covers the outside of the wire and the components on the surface of the wire.
- the purpose of the inner layer coating is to prevent the wires of adjacent structures from coming into contact with each other.To increase the cross-sectional area of the strength members in the cross-sectional area of the rope and to make a small-diameter ' ⁇ strength rope, It is better to make it as thin as possible within the range that can achieve. For that purpose, the range of 0.2-0.5 thigh is good.
- the purpose of the outer layer coating is to transmit the power from the sheave to the strength member of the rope, and to reduce the abrasion due to long-term contact with the sieve.The thickness is sufficient to withstand the abrasion. is necessary. For that purpose, the range of 5 to 1.0 mm is good considering the various conditions in which the mouth is used.
- the metal wire having a small diameter is used, not only the rigidity is high and there is no aging deterioration, but also the flexibility is excellent and the small diameter When using it wound around, no excessive force acts on the strength member.
- the structure is made by twisting metal wires and the coated structure is twisted into a rope, so the wires do not directly contact or slip between the structures, resulting in abrasion resistance. Excellent long life can be achieved.
- the coated structure is coated on a twisted rope to form a rope, the coefficient of friction with the sieve can be made appropriate, and the abrasion of the inner layer coating and the wire can be prevented. Since the coating applied to the structure and the coating applied to the rope are separate, a two-layer coating structure is used, so that the material can be optimized to achieve the functions required for each coating, improving design flexibility and improving manufacturing. Can be realized.
- the rope according to the present invention can optimize the friction coefficient between the rope and the sheep even when used with a small-diameter sheep, and can achieve a long service life. Can be As a result, it is possible to realize an elevator that is space-saving and has a long rope replacement cycle. As a result, it is possible to reduce the maintenance cost as well as the initial cost of the elevator.
