Definitions

  • the present invention relates to a moving wire rope used for an elevator moving cord or the like.
  • the wire rope used for the elevator moving rope is configured by further twisting a strand in which a plurality of wires are twisted together around a core material.
  • a core material In conventional wire ropes for moving cords, many fiber cores and steel cores are used. Such a core material is gradually worn and thinned by repeated bending after a certain period of use. When the core material is thinned, there is a problem that abrasion powder is generated due to contact between the strands, the wire rope is stretched, the wire rope itself is damaged, and the strength is lowered. Therefore, a wire rope using a resin such as polyethylene or polypropylene as a core material has been proposed (for example, see Patent Document 1).
  • the standard for exchanging wire rope for moving cables is stipulated by each law (for example, occupational safety and health regulations, crane safety regulations, gondola structure standards, elevator inspection standards (JISA4302), etc.), and the rope diameter is below a certain level. It must be replaced when it becomes thin. Therefore, it is an important matter to maintain and manage the diameter (thickness) of the moving wire rope. This is because if the timing for measuring the diameter state is delayed or there is a measurement error, it may lead to a serious accident.
  • the conventional wire rope for moving cords has a problem that it is not easy to confirm the rope diameter regardless of whether it is a fiber core or a resin core. That is, when measuring the diameter using a measuring tool (vernier caliper) as specified in JISG3525, it is necessary to stop the machine (for example, an elevator) and perform measurement at a plurality of locations. It takes time and effort. At this time, if the number of measurement points is increased, the accuracy of the state detection of the moving wire rope can be improved, but if the machine stoppage is taken into consideration, there are time restrictions and the measurement points are also limited. There is a limit to the improvement of accuracy.
  • the present invention has been made in view of such a problem, and an object thereof is to provide a wire rope for moving rope that is excellent in performance and facilitates the state measurement of the rope diameter and contributes to safety improvement. To do.
  • a wire rope for moving cords is a wire rope for moving cords formed by twisting a plurality of strands around a resin core which is a resin core material, and the resin rope
  • the core is composed of a plurality of resin layers, and the resin materials of the adjacent resin layers are different or / and the color arrangement of the adjacent layers is different.
  • each layer is made of a different resin material, and each layer is made of a different color, it is possible to easily measure the state of the rope diameter.
  • the wire rope for moving ropes changes due to wear over time, and the resin material constituting each layer wears sequentially from the outer layer into powder, so the rope diameter depends on the amount of powder generated. It is possible to estimate the state of the rope, and to obtain a rough standard for rope replacement.
  • the resin layer on the outer side of the center side of the resin core is configured to have higher durability against abrasion of the resin layer.
  • a multi-layered structure using a relatively inexpensive resin material on the inner side where abrasion is difficult can be achieved by using a resin material having excellent durability against wear on the outer side where wear is likely to proceed.
  • a wire rope for moving cords with a resin core is realized.
  • the color arrangement of the resin layer outside the resin layer on the center side of the resin core is a light color system.
  • the resin core has a multi-layer structure made of different materials, the state of the rope diameter can be judged by the resin material that has become powder after being worn. As a result, it is possible to obtain a standard for rope replacement standards, which in turn contributes to an improvement in safety.
  • FIG. 1 is a cross-sectional view of a moving wire rope according to this embodiment.
  • the moving wire rope 1 is a wire rope used for an elevator moving rope or the like, which is formed by twisting a plurality of strands 2 around a core material.
  • a wire rope used for an elevator moving rope or the like which is formed by twisting a plurality of strands 2 around a core material.
  • eight strands 2 are twisted together is illustrated, but there are cases where the strands are composed of six strands.
  • the wire rope 1 for moving cords is provided with a resin core 3 as a core material.
  • the resin core 3 is composed of a first resin layer 4 and a second resin layer 5 and has a multilayer structure.
  • the 1st resin layer 4 and the 2nd resin layer 5 which comprise the resin core 3 are formed with thermoplastic resin materials, such as polyethylene, a polypropylene, and polyester.
  • the resin material constituting the first resin layer 4 and the resin material constituting the second resin layer are different from each other.
  • the first resin layer 4 serving as the central portion is made of a relatively inexpensive polyethylene or polypropylene resin material
  • the second resin layer 5 serving as the outside is made of a highly durable resin material such as high-density polyethylene or polyester.
  • the low-cost but high-performance resin core 3 can be configured.
  • the resin core has a multi-layer structure, and the materials constituting each layer are different, so that the diameter of the rope that changes over time can be confirmed by the resin material that has become worn and powdered. become.
  • the fact that the resin material is powdered due to wear means that the layer is exposed at any point.
  • the thickness of each layer is preferably 1 mm or more in order to generate a certain amount of powder that can be confirmed visually by the measurer.
  • FIG. 2 is a diagram for explaining the ratio of the resin core.
  • the diameter B of the resin core 3 before the strands are twisted is preferably 55 to 65% of the rope diameter A. This is because if it falls below 55%, finding a decrease in the rope diameter may be delayed. On the other hand, if it exceeds 65%, the rope diameter will be reduced at an earlier stage than the time when the rope should be replaced, and the life of the rope may be shortened.
  • the diameter B of the resin core is preferably 35 to 45% of the rope diameter A. The reason is the same as above.
  • FIG. 3 is a cross-sectional view showing another example of the resin core.
  • the resin core 3 a shown in FIG. 3 is composed of the first resin layer 4, the second resin layer 5, and the third resin layer 6.
  • the color arrangement of each layer may be different instead of changing the resin material. For example, if colors close to the primary colors of cyan (C), magenta (M), and yellow (Y), which are the three primary colors, are arranged in each layer, the diameter of the rope can be easily adjusted by the resin material that has become worn and powdered. The state of can be confirmed.
  • the difference in color arrangement may be different depending on the shades of similar colors. In this case, for example, it is preferable to arrange the colors from the dark color system to the light color system from the inner side to the outer side of the center of the heart.
  • the rope If the rope is worn and the resin material becomes powder, it can be determined to which layer the rope has been worn depending on the color of the powder. Further, since the rope is worn over the long direction, it is possible to visually determine that a layer having a different color scheme is exposed at any location.
  • the thickness of each layer may be different.
  • the thickness may be increased using a resin material with excellent durability, and a different color may be used, or the resin material with excellent durability and a relatively inexpensive resin material may be used.
  • a resin core suitable for the equipment using the wire rope for moving cords such as alternately arranging and increasing or decreasing the thickness of each layer. If the resin material of at least the adjacent layers of the multilayer structure is made different or the color arrangement is made different, the state of the rope diameter can be grasped by the powder of the resin material caused by the wear of the rope. There are many possible patterns for the resin core having a suitable multilayer structure.
  • the present invention can be applied as a moving wire rope used for an elevator moving cord or the like.
