[0050] Embodiments are described with reference to the accompanying drawings. In addition, the same or corresponding portions are denoted by the same reference numerals in each drawing. Repetitive description of such portions is simplified or omitted even if necessary.
[0051] Embodiment 1
[0052] Figure 1 is an example of a structure diagram of an elevator to which the rope in Embodiment 1 is applied.
[0053] In the elevator of Figure 1 , a hoistway 1 penetrates each floor of a building. A machine room 2 is provided directly above the hoistway 1.
[0054] A traction machine 3 is provided in the machine room 2. A sheave 4 is attached to a rotating shaft of the traction machine 3. A plurality of ropes 5 are wound side by side as a plurality of hoisting ropes on an outer peripheral surface of the sheave 4.
[0055] A car 6 is provided inside the hoistway 1. The car 6 is supported on one side of the plurality of ropes 5. A counterweight 7 is provided inside the hoistway 1. The counterweight 7 is supported on the other side of the plurality of ropes 5.
[0056] The traction machine 3 is driven in accordance with an instruction from a control device not shown. The sheave 4 rotates in response to the driving of the traction machine 3. The rope 5 moves in response to the rotation of the sheave 4. The car 6 and the counterweight 7 are raised in opposite directions to each other in response to the movement of the rope 5.
[0057] Next, a high-strength fiber aggregate is described using Figure 2 The rope 5 is described.
[0058] Figure 2 is a sectional view of the rope in Embodiment 1.
[0059] As shown in Figure 2 , the rope 5 has a core material 8 and a plurality of first steel materials 9.
[0060] The core material 8 is a high-strength fiber aggregate. The core material 8 is subjected to profile processing.
[0061] The plurality of first steel materials 9 are each, for example, a steel strand. The plurality of first steel materials 9 are each disposed at an outer periphery of the core material 8. The plurality of first steel materials 9 are each, for example, twisted with the core material 8 as a center.
[0062] The core material 8 and the plurality of first steel materials 9 share a load in a tensile direction of the rope 5.
[0063] Next, a high-strength fiber aggregate is described using Figure 3 and Figure 4 .
[0064] Figure 3 is a side view of the high-strength fiber aggregate of the rope in Embodiment 1. Figure 4 is an enlarged view of a cross section of the high-strength fiber aggregate of the rope in Embodiment 1.
[0065] As shown in Figure 3 , the high-strength fiber aggregate has a plurality of high-strength fiber filaments 10. The number of the high-strength fiber filaments 10 is, for example, several hundred to several ten thousand. The number of the high-strength fiber filaments 10 is, for example, several ten thousand. The outer diameter of the high-strength fiber filaments 10 is, for example, several μm to several tens of μm.
[0066] The plurality of high-strength fiber filaments 10 are maintained in a state of being gathered together with each other. The plurality of high-strength fiber filaments 10 are, for example, maintained in a state of being aligned in a length direction with each other. In Figure 3 , the orientation of the high-strength fiber filaments 10 is indicated by a solid line. In this state, the plurality of high-strength fiber filaments 10 are subjected to profile processing in a manner that a cross section becomes a predetermined shape. The plurality of high-strength fiber filaments 10 are, for example, subjected to profile processing in a manner that a cross section becomes a circular shape.
[0067] As shown in Figure 4 , the plurality of high-strength fiber filaments 10 are maintained in a state of being filled in an inside of a matrix resin 11.
[0068] To shape the cross-section of a long, high-strength fiber assembly into a predetermined shape, firstly, multiple high-strength fiber filaments 10 are immersed in a liquid matrix resin 11 before curing. Then, the multiple high-strength fiber filaments 10 are pulled into and aligned inside a mold of a predetermined shape. Next, the multiple high-strength fiber filaments 10 are pulled out of the mold. Inside the mold, the multiple high-strength fiber filaments 10 are continuously heated. At this time, the matrix resin 11 cures within the multiple high-strength fiber filaments 10 through heating.
[0069] According to Embodiment 1 described above, a plurality of high-strength fiber filaments 10 are maintained in a state where they are aggregated together. For example, the plurality of high-strength fiber filaments 10 are maintained in a state where their length directions are aligned with each other. The plurality of high-strength fiber filaments 10 are subjected to irregular shaping processing. Therefore, it is possible to maintain the increased density of the plurality of high-strength fiber filaments 10. As a result, the strength of the high-strength fiber aggregate can be further improved.
[0070] Specifically, multiple high-strength fiber filaments 10 are maintained in a state of being filled inside the matrix resin 11. Therefore, it is easy to maintain the multiple high-strength fiber filaments 10 in an aggregated state. As a result, the shape of the multiple high-strength fiber filaments 10 does not become distorted, and the rope 5 can be manufactured easily and inexpensively.
[0071] Alternatively, a flexible resin can be used as the base resin 11. Specifically, a resin that is flexible and does not easily break when subjected to external force can be used as the base resin 11. In this case, the flexibility of the rope 5 can be ensured. As a result, the bending properties of the rope 5 can be ensured.
[0072] For example, thermosetting epoxy resin or thermosetting polyurethane resin can be used as the flexible resin.
[0073] For example, in thermosetting epoxy resins, any liquid main agent containing one or more of the following in its molecule: polyoxyethylene bonds, urethane bonds, and butadiene rubber, and containing two or more epoxy groups, is sufficient. The epoxy resin can be cured simply by mixing the main agent with the curing agent and then heating it.
[0074] For example, from the viewpoint of hydrolysis resistance, ether-based polyurethane resins can be used as thermosetting polyurethane resins. For example, various polyisocyanate compounds can be used to cure ether polyols such as polytetramethylene ether glycol and polypropylene glycol.
[0075] Based on these resins, high-strength fiber assemblies can be easily maintained in a predetermined shape. Therefore, the tightness of the multiple high-strength fiber filaments 10 can be ensured. As a result, the flexibility of the rope 5 can be ensured after the resin has cured.
[0076] Alternatively, if there are no manufacturing issues, thermoplastic resins can also be used as flexible resins.
[0077] Next, use Figure 5 The first modified example of a high-strength fiber assembly will be described.
[0078] Figure 5 This is a side view of a first variation of the high-strength fiber assembly of the rope in Embodiment 1.
[0079] like Figure 5 As shown, the high-strength fiber assembly is a high-strength fiber yarn 12. Within the high-strength fiber yarn 12, multiple high-strength fiber filaments 10 are maintained in a twisted state. Figure 5 In the diagram, the orientation of the high-strength fiber filaments 10 is indicated by solid lines. In this state, multiple high-strength fiber filaments 10 are subjected to irregular shaping.
[0080] For example, in the case of making the cross-section of a long strip of high-strength fiber assembly circular, firstly, the high-strength fiber yarn 12 is impregnated with a liquid matrix resin 11 before curing. Then, the high-strength fiber yarn 12 is twisted. As a result, the remaining matrix resin 11 is removed. In this state, the high-strength fiber yarn 12 is continuously heated. As a result, the matrix resin 11 cures in the high-strength fiber yarn 12. At this point, the cross-section of the high-strength fiber assembly naturally becomes circular. In this case, the fiber content of the high-strength fiber yarn 12 is higher than... Figure 4 The high-strength fiber aggregate has a high fiber content. The high-strength fiber yarn 12 has a mass-to-strength ratio of... Figure 4 The mass-to-strength ratio of high-strength fiber aggregates is higher than that of high-strength aggregates.
[0081] For example, when the cross-section of a long, high-strength fiber assembly is shaped other than circular, the high-strength fiber yarn 12 is first impregnated with a liquid matrix resin 11 before curing. Then, the high-strength fiber yarn 12 is fed into a mold of a pre-defined shape. At this time, the high-strength fiber yarn 12 is continuously heated inside the mold. As a result, the matrix resin 11 cures within the high-strength fiber yarn 12.
[0082] According to the first modified example described above, multiple high-strength fiber filaments 10 are maintained in a twisted state. Therefore, it is possible to easily and inexpensively manufacture high-strength fiber assemblies with greater flexibility.
[0083] In this case, when the high-strength fiber assembly is bent, localized stress caused by compression or tension is less likely to occur in the multiple high-strength fiber filaments 10. Therefore, buckling of the high-strength fiber assembly can be suppressed. As a result, the fatigue durability of the high-strength fiber assembly can be improved. Furthermore, by improving the fatigue durability of the high-strength fiber assembly, the fatigue durability of the rope 5 can be improved.
[0084] Furthermore, by processing the high-strength fiber yarn 12 into a special shape, the load is distributed more evenly among the multiple high-strength fiber filaments 10. Therefore, a larger load can be supported in the high-strength fiber assembly.
[0085] Next, use Figure 6 A second modified example of a high-strength fiber assembly will be described.
[0086] Figure 6 This is a side view of a second variation of the high-strength fiber assembly of the rope in Embodiment 1.
[0087] like Figure 6 As shown, the high-strength fiber assembly is a high-strength fiber strand 13. Within the high-strength fiber strand 13, multiple high-strength fiber yarns 12 are twisted together. For example, in... Figure 6 In this structure, six high-strength fiber yarns 12 are twisted together around a central high-strength fiber yarn 12. Although not in... Figure 6 As shown, in the high-strength fiber yarn 12, multiple high-strength fiber filaments 10 are twisted together. In this state, the high-strength fiber strands 13 are subjected to profile processing.
[0088] exist Figure 6 In the diagram, the boundary between adjacent high-strength fiber yarns 12 is indicated by a solid line. In reality, this boundary is mostly invisible.
[0089] According to the second variation described above, multiple high-strength fiber yarns 12 are twisted together. Therefore, the entire high-strength fiber strand 13 can share the load.
[0090] Furthermore, by twisting multiple high-strength fiber yarns 12 together to form a high-strength fiber strand 13, the overall strength of the high-strength fiber strand 13 and even the rope 5 can be ensured even in the presence of splices in the high-strength fiber yarns 12. Therefore, the high-strength fiber yarns 12 can be connected seamlessly without splices along the entire length of the rope 5. In this case, it is not necessary to prepare high-strength fiber filaments 10 of a length corresponding to the length of the rope 5. As a result, the manufacturing cost of the high-strength fiber yarns 12 can be reduced.
[0091] Implementation Method 2
[0092] Figure 7This is a side view of the high-strength fiber assembly of the rope in Embodiment 2. Furthermore, parts that are the same as or equivalent to those in Embodiment 1 are labeled with the same reference numerals. Descriptions of these parts are omitted.
[0093] like Figure 7 As shown, the high-strength fiber assembly comprises multiple high-strength fiber yarns 12. Although not in... Figure 7 As shown, in each of the plurality of high-strength fiber yarns 12, the plurality of high-strength fiber filaments 10 are maintained in a state of being twisted together. For example, the plurality of high-strength fiber filaments 10 are maintained in a state of being twisted together by a first matrix resin. In this state, the plurality of high-strength fiber yarns 12 are respectively shaped with a circular cross-section.
[0094] Multiple high-strength fiber yarns 12 are maintained in a state of being aggregated together. Specifically, the multiple high-strength fiber yarns 12 are maintained in a state where their length directions are aligned with each other. For example, the multiple high-strength fiber yarns 12 are maintained in a state where their length directions are aligned with each other by means of a second matrix resin. The multiple high-strength fiber yarns 12 are subjected to irregular shaping. For example, the multiple high-strength fiber yarns 12 are subjected to irregular shaping in a way that the cross-section is similar to a trapezoid. Specifically, the shape of the cross-section is the shape obtained by removing the more central sector from a sector of a predetermined size.
[0095] For example, when the cross-section of the long, high-strength fiber assembly is shaped to a predetermined form, multiple high-strength fiber yarns 12 are formed in the same manner as in the variation of Embodiment 1. Then, the multiple high-strength fiber yarns 12 are wound onto multiple spools, etc. Then, the multiple high-strength fiber yarns 12 are pulled out from the multiple spools, etc. Then, the multiple high-strength fiber yarns 12 are impregnated with a second matrix resin. Then, the multiple high-strength fiber yarns 12 are assembled together so that their length directions are aligned. Then, the multiple high-strength fiber yarns 12 are drawn into a mold of a predetermined shape. Then, the multiple high-strength fiber yarns 12 are continuously heated inside the mold. As a result, the second matrix resin cures within the multiple high-strength fiber yarns 12.
[0096] For example, when the second matrix resin is a thermoplastic resin, a plurality of high-strength fiber yarns 12 are drawn into the interior of a mold with their length directions aligned. In this state, the plurality of high-strength fiber yarns 12 are impregnated with the molten second matrix resin. Then, the plurality of high-strength fiber yarns 12 are pulled out of the mold. Afterward, the plurality of high-strength fiber yarns 12 are cooled. As a result, the second matrix resin solidifies within the plurality of high-strength fiber yarns 12.
[0097] According to Embodiment 2 described above, a plurality of high-strength fiber yarns 12 are maintained in a state of being aggregated together. Specifically, the plurality of high-strength fiber yarns 12 are maintained in a state where their length directions are aligned with each other. Therefore, a larger load can be supported in the high-strength fiber aggregate.
[0098] In addition, the first matrix resin and the second matrix resin can be appropriately selected. For example, the first matrix resin can also be mixed with... Figure 3 The matrix resin 11 is the same.
[0099] The first matrix resin needs to be concentrated on impregnating each high-strength fiber filament 10 with an outer diameter of several μm to tens of μm. Therefore, the first matrix resin needs to be of low viscosity before curing. In contrast, the second matrix resin only needs to impregnate multiple high-strength fiber yarns 12. Therefore, the viscosity of the second matrix resin can be higher than that of the first matrix resin before curing.
[0100] Next, use Figure 8 A modified example of a high-strength fiber assembly is described.
[0101] Figure 8 This is a side view of a modified example of the high-strength fiber assembly of the rope in Embodiment 2.
[0102] like Figure 8 As shown, multiple high-strength fiber yarns 12 are maintained in a twisted state. The multiple high-strength fiber yarns 12 have undergone irregular shaping.
[0103] For example, when the cross-section of the long, high-strength fiber body is formed into a predetermined shape, multiple high-strength fiber yarns 12 are formed in the same manner as in the modified example of Embodiment 1. Then, the multiple high-strength fiber yarns 12 are wound onto multiple spools, etc. Then, the multiple high-strength fiber yarns 12 are pulled out from the multiple spools, etc. Then, the multiple high-strength fiber yarns 12 are twisted together. Then, the multiple high-strength fiber yarns 12 are impregnated with a second matrix resin. Then, the multiple high-strength fiber yarns 12 are drawn into a mold of a predetermined shape. At this time, the multiple high-strength fiber yarns 12 are continuously heated inside the mold. As a result, the second resin cures within the multiple high-strength fiber yarns 12.
[0104] For example, when the second matrix resin is a thermoplastic resin, a plurality of high-strength fiber yarns 12 are drawn into the interior of a mold while twisted together. In this state, the plurality of high-strength fiber yarns 12 are impregnated with the molten second matrix resin. Then, the plurality of high-strength fiber yarns 12 are pulled out of the mold. Afterward, the plurality of high-strength fiber yarns 12 are cooled. As a result, the second matrix resin solidifies within the plurality of high-strength fiber yarns 12.
[0105] According to the modified example described above, the multiple high-strength fiber yarns 12 are maintained in a twisted state. Therefore, when manufacturing a high-strength fiber assembly, it is possible to suppress shape deformation of the high-strength fiber assembly. Moreover, even if the rope 5 is repeatedly bent, it is possible to suppress shape deformation of the high-strength fiber assembly.
[0106] Implementation Method 3
[0107] Figure 9 This is a side view of the high-strength fiber assembly of the rope in Embodiment 3. Furthermore, parts that are the same as or equivalent to those in Embodiment 1 are labeled with the same reference numerals. Descriptions of these parts are omitted.
[0108] like Figure 9 As shown, the high-strength fiber assembly comprises a plurality of high-strength fiber strands 13. In each of the plurality of high-strength fiber strands 13, a plurality of high-strength fiber yarns 12 are twisted together. In each of the plurality of high-strength fiber yarns 12, a plurality of high-strength fiber filaments 10 are twisted together.
[0109] Multiple high-strength fiber strands 13 are maintained in a state where their length directions are aligned with each other. The multiple high-strength fiber strands 13 are subjected to irregular shaping. For example, the multiple high-strength fiber strands 13 are irregularly shaped using a matrix resin 11. Figure 9 In the process, 7 high-strength fiber strands 13 were processed into a trapezoidal cross-section.
[0110] exist Figure 9 In the diagram, the boundary between adjacent high-strength fiber strands 13 is represented by a solid line. In reality, this boundary is mostly invisible.
[0111] According to Embodiment 3 described above, the plurality of high-strength fiber strands 13 are maintained in a state where their length directions are aligned with each other. The plurality of high-strength fiber strands 13 are subjected to irregular shaping. Therefore, the outer diameter of the high-strength fiber assembly can be made larger. As a result, the outer diameter of the rope 5 can be further increased. The breaking strength of the rope 5 can be further improved.
[0112] Next, use Figure 10 A modified example of a high-strength fiber assembly is described.
[0113] Figure 10 This is a side view of a modified example of the high-strength fiber assembly of the rope in Embodiment 3.
[0114] like Figure 10 As shown, multiple high-strength fiber strands 13 are maintained in a twisted state. The multiple high-strength fiber strands 13 are subjected to profiled processing. For example, the multiple high-strength fiber strands 13 are profiled using a matrix resin 11. Figure 10In the process, six high-strength fiber strands 13 are twisted together with one high-strength fiber strand 13 as the center. The seven high-strength fiber strands 13 are shaped in a trapezoidal cross-section.
[0115] exist Figure 10 In the diagram, the boundary between adjacent high-strength fiber strands 13 is represented by a solid line. In reality, this boundary is mostly invisible.
[0116] According to the modified example described above, the multiple high-strength fiber strands 13 are maintained in a twisted state. The multiple high-strength fiber strands 13 are subjected to irregular shaping. Therefore, after the multiple high-strength fiber strands 13 are subjected to irregular shaping, the shape deformation of the high-strength fiber assembly can be suppressed. Moreover, compared with the case where the multiple high-strength fiber strands 13 are irregularly shaped so that their length directions are aligned, the load can be distributed more evenly among the multiple high-strength fiber strands 13.
[0117] Implementation Method 4
[0118] Figure 11 This is a cross-sectional view of the rope in Embodiment 4. Furthermore, parts that are the same as or equivalent to those in Embodiment 1 are labeled with the same reference numerals. Descriptions of these parts are omitted.
[0119] like Figure 11 As shown, the core material 8 is obtained by twisting and shaping multiple high-strength fiber assemblies together into linear bodies. Figure 11 In this structure, six high-strength fiber assemblies are formed by twisting these assemblies together, with one high-strength fiber assembly at the center. The central high-strength fiber assembly has a circular cross-section, while the six surrounding high-strength fiber assemblies have trapezoidal cross-sections. In this state, the core material 8 has undergone irregular shaping.
[0120] According to Embodiment 4 described above, the core material 8 is obtained by twisting and shaping multiple high-strength fiber assemblies together into linear bodies. Therefore, the flexibility of the rope 5 can be improved.
[0121] Next, use Figure 12 The following describes a variation of rope 5.
[0122] Figure 12 This is a cross-sectional view of a modified example of the rope in embodiment 4.
[0123] exist Figure 12 In this process, the core material 8 is formed by twisting together six high-strength fiber assemblies that have been irregularly shaped into a fan shape. In this state, the core material 8 has undergone irregular shaping.
[0124] According to the modified example described above, the core material 8 is formed by twisting together six high-strength fiber assemblies that have been irregularly shaped into a fan shape. In this case, the flexibility of the rope 5 can be improved without the need for multiple high-strength fiber assemblies.
[0125] Implementation Method 5
[0126] Figure 13 This is a cross-sectional view of the rope in Embodiment 5. Furthermore, parts that are identical or equivalent to those in the variations of Embodiment 4 are labeled with the same reference numerals. Descriptions of these parts are omitted.
[0127] like Figure 13 As shown, the rope 5 has multiple first fiber assemblies 16 and multiple second steel members 17.
[0128] The multiple first fiber assemblies 16 are formed by twisting together multiple high-strength fiber assemblies. The multiple first fiber assemblies 16 are respectively disposed on the outer side of the multiple first steel members 9.
[0129] The plurality of second steel members 17 are steel strands. The plurality of second steel members 17 are respectively disposed on the outer side of the plurality of first fiber assembly members 16.

For example, these ropes 5 and any aspect of the rope structure can also be applied to elevators with a 2:1 rope winding method. For example, these ropes 5 and any aspect of the rope structure can also be applied to double-decker elevators.
[0223] In addition, these ropes 5 and any of the rope structures can also be used in elevator speed governors.
[0224] Furthermore, these ropes 5 and any part of the rope structure can also be applied to high-rise elevators with a traction height exceeding 75 meters. In this case, the higher the traction height, the greater the weight reduction effect of the total weight of the ropes 5 compared to conventional ropes 5.
