Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a fiber rope, particularly a fiber rope with a protective belt.

[0002]

[Prior art]

 Fiber ropes are widely used for ships, fishing, power transmission, civil engineering, forestry, sports, and so on. Since such a fiber rope is made of fiber as a constituent material, for example, when used as a hoser, a tag rope, a mooring rope, or the like in a ship or the like, a hard other material such as a roll or a fuller leader (a window through which the mooring line of the ship is taken out) is used. When contact with an object is repeated, the fibers in the contact portion are worn out due to wear, resulting in a problem that strength is reduced.

[0003] As a measure for preventing such local wear of the fiber rope, a tubular body made of canvas or a synthetic resin sheet is protected by being fitted over the fiber rope. It was difficult to fix without displacement, and the position was easily shifted after a relatively short period of use, and there was a problem in the reliability of protection. Also, when the protective material is worn out and replaced, it must be moved to the end of the fiber rope and replaced because it is cylindrical, and the eye is cut off because the end is ice-priced. There was a problem that the ice place had to be reworked after removing the protective material and fitting new protective material.

[0004]

[Problems to be solved by the invention]

 The present invention has been made in order to solve the above-mentioned problems, and an object of the present invention is to easily protect any desired part without shifting, and to easily replace the part. To provide a fiber rope with a protective belt at a low cost.

[0005]

Means for Solving the Problems In order to achieve the above object, the present invention relates to a braid having a braid structure having a plurality of strands as one set, and a braid having a width substantially equal to or greater than the braided strand. A plurality of belts of the same number as the number of strands are braided so as to lie under the other outer strands crossing each other along the outer surface in the longitudinal direction of the strands and cover the outer surface of the fiber rope body. And The belt is preferably made of synthetic fiber having good abrasion resistance.

[0006]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Fig. 1 shows an example in which the fiber rope according to the present invention is used as a tag rope, 1 is a large ship such as a tanker, 2 is a tugboat located in the traveling direction of the large ship 1, 3 is a fiber rope according to the present invention. Yes, after being appropriately pulled out from the fixed part of the large vessel 1 in the captain's direction, it is bent in the ship's side and led to the tugboat 2 to be towed. A is a portion to be withdrawn from the ship 1 in the ship side as a portion to be protected, and this portion is in contact with the hull structure and is easily worn.

FIG. 2 to FIG. 6 show an embodiment of the fiber rope 3 according to the present invention, 4 is a fiber rope main body, and an ice price 4a is provided at an end. 5a, 5b, 5c and 5d are protection belts covering the surface of the protection target portion A of the fiber rope main body 4.

The fiber rope main body 4 is made of general-purpose synthetic fibers such as polyester, polyethylene, and polypropylene, and high-strength and high-elasticity fibers such as wholly aromatic polyamide and polyarylate, and is composed of a large number of yarns of these fibers. A braided rope in which the strands are braided is preferable in terms of attaching the belt 5a or 5d so as not to be displaced, in addition to characteristics such as non-rotation and non-kink.

Examples of the fiber rope body 4 include an eight-punched structure in which four strands from Z and four strands from S are arranged two by two and alternately combined, or six strands from Z and A 12-strand structure in which six strands from S are drawn and combined two by two, and a braided body with an eight-strand or 12-strand structure provided on the outer periphery of a braided core rope to be doubled, etc. .

The material and thickness of the protective belts 5 a, 5 b, 5 c, 5 d are appropriately selected according to the required durability. In general, fibers having good abrasion resistance, such as general-purpose synthetic fibers such as polyester, It is selected from high-strength and high-elasticity fibers such as aromatic polyamides, or a combination of these fibers, or a combination of synthetic fibers and metal fibers, and is formed into a flexible and flexible fiber-based woven body. The protective belts 5a, 5b, 5c, and 5d have a width W substantially equal to or appropriately large as each of the aligned strands of the fiber rope main body 4, and the number of such belts is the same as the number of the strands. Can be

In this example, the fiber rope main body 4 has an eight-punch structure and is constituted by four sets of strands 4 a, 4 b, 4 c, and 4 d which form a set of two. Four belts 5a to 5d are used, and each belt 5a, 5b, 5c, 5d extends along the outer surface of the corresponding set strand 4a, 4b, 4c, 4d in the longitudinal direction and crosses the other set strand. Underneath this, it repeats along the longitudinal outer surface of the corresponding braid strand again, and is braided identically to the rope configuration.

As shown in FIG. 5, the belts 5a to 5d are provided with a pointed guide piece 50 whose tip is narrowed in order to make it easier to dive under another set strand that crosses. Such a guide piece 50 may be cut off after completion. As shown in FIG. 2, the belts 5a to 5d are fixed to the fiber rope main body 4 at the end of the portion A to be protected by a tape or a string. The protection target portion A is usually a required range (local portion) of the fiber rope main body 4, but may extend over substantially the entire length of the fiber rope main body 4 in some cases.

[0013]

Operation of the embodiment

 In the fiber rope 3 of the present invention, as shown in FIGS. 3 and 4, the entire cross section of the fiber rope body 4 is covered with independent flat belts 5a to 5d. Therefore, even if any part on the circumference comes into contact with another hard object, it does not come into direct contact with the fiber rope body 4, so that wear can be reliably prevented. Further, since the protection means is not a bag, but a plurality of independent belts 5a to 5d are braided along the outer surface in the longitudinal direction of each set strand 4a, 4b, 4c, 4d, the fiber rope main body 4 The fiber rope main body 4 can sufficiently follow the movement and state change such as bending of the fiber rope, and can sufficiently exhibit the original performance of the fiber rope main body 4. Further, since the fiber rope main body 4 does not become a flat protrusion, the fiber rope body 4 can be easily passed through or wound on a drum or a roll.

In addition, the belts 5a, 5b, 5c and 5d are attached to each of the strands 4a, 4b, 4c and 4d of the braided fiber rope body 4 as shown in FIG. And dive under the other strands crossing 5d along the surface in the longitudinal direction of the strand. For example, in FIG. 6, the belt 5d for the braided strand 4d dives below the intersecting braided strand 4b and again along the surface of the braided strand 4d, and the belt 5a for the braided strand 4a moves below the intersecting braided strand 4d. It descends and follows the surface of the set strand 4a again. In this way, the belt is held down by the other strands crossed using the braided structure, and the belt is held down by the same strands, and this is repeated according to the braid pitch. No misalignment occurs during use, and it is firmly held at the target protection target portion A. By changing the thickness and material of the protective belt, it is possible to freely meet the required durability.

In addition, since the belts 5 a to 5 d are knitted from the side of the protection target portion A instead of the cylinder, the construction can be easily performed on site regardless of the position of the protection target portion A on the fiber rope body 4. Even when the belts 5a to 5d are worn and replaced, the belts 5a to 5d can be easily removed from the fiber rope body 4 by dipping under the other set strands crossing from the belt end and returning. There is no need to cut off the ice price.

[0016]

[Effect of the invention]

 According to the first aspect of the present invention described above, the width of the fiber rope body 4 having a braided structure in which a plurality of strands 4a, 4b, 4c, and 4d are formed as one set is substantially equal to or more than the width of the set strand. A plurality of belts 5a, 5b, 5c, 5d, the number of which is equal to the number of braided strands, are braided so that the other braided strands to be crossed are sunk along the outer surfaces in the longitudinal direction of the braided strands. Since the outer surface of the main body 4 is covered, any part that is easily worn can be reliably protected without impairing the rope performance, and the belts 5a, 5b, 5c, and 5d can be sunk by other strands. Since it is braided into the same place as the structure of the rope, it does not shift during use of the rope, it can be securely held in position, and the worn belt can be replaced. Even without disconnecting from the end of fiber rope body, excellent effects such as can easily be anywhere is obtained. According to claim 2, since the belt is made of synthetic fiber having good abrasion resistance, the belt is excellent in compatibility with the fiber rope main body 4 and is flexible, so that the performance of the fiber rope main body 4 is not impaired. The effect is obtained.
