Description

Technical Field

[0001] The invention relates to the technical field of ropes, and in particular to a strand rope and a splicing method thereof. Background Art

[0002] Strand ropes include single-strand ropes and multi-strand ropes, and multi-strand ropes are made of multiple bone strips woven and bonded. Among them, twelve-strand ropes are usually composed of twelve thin ropes or fibers, which are woven and twisted together. Due to its structure and strength, this rope is often used in situations that require high durability and strength. Twelve-strand ropes are used in many fields, including sailing, mountaineering, construction, rope art, etc.

[0003] When splicing twelve-strand ropes, the traditional splicing method is to rotate the rope 180° to form a closed loop, and then unravel the strands at the end. Figure 8 The strands are marked as 1-1 to 12-1 in the figure and are incorporated into the original rope. Figure 8 As shown in the figure marked with 1 to 12, they are fixed by overlapping each other to form a very long plug-in section, such as Figure 8 As shown in the box, the number of strands in the spliced ​​section changes from 12 to 24, and the diameter is much larger than the original rope diameter. Fig. 9 As shown, the pipa head is too large to pass through a hole with specific requirements, and has low applicability. Not only is the operation complicated, but it also wastes raw materials. Therefore, we propose a strand rope and a splicing method thereof to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that when splicing twelve-strand ropes, the traditional splicing method is cumbersome to operate, the strands of the splicing section are changed from 12 to 24, the diameter is much larger than the original rope diameter, and it is time-consuming and material-consuming, and to propose a strand rope and its splicing method.

[0005] In order to achieve the above object, the present invention adopts the following technology: a twelve-strand rope, including a main rope, and also including a closed eyelet and an inserted braided section, wherein the main rope and the closed eyelet are connected by the inserted braided section, wherein the main rope, the closed eyelet and the inserted braided section are all formed by braiding and twisting twelve strands;

[0006] The closed eyelet is formed by bending the rope 180°.

[0007] As a further description of the above technical solution: the twelve strands are numbered as strands 1 to 12 in sequence, wherein the strands numbered with odd numbers have a twist direction of "Z" and the strands numbered with even numbers have a twist direction of "S".

[0008] As a further description of the above technical solution: "Z" twist direction indicates counterclockwise twisting, "Z" twist direction indicates clockwise twisting, the inserted rope strands are Z, S, Z, S, Z, S in sequence, and the remaining six rope strands in the rope are Z, S, Z, S, Z, S in sequence.

[0009] In order to solve the above technical problems, the present invention also provides a method for splicing the twelve-strand rope, comprising the following steps:

[0010] S1: marking preparation. When splicing twelve strands of rope, first bend the rope 180° to form a closed eye ring, then determine the length of the splicing section and make markings. The strands are marked with numbers 1 to 6, and the strands with the same number are the same strand;

[0011] S2: Select strand 3 and pull it out along the rope direction;

[0012] S3: When the strand 3 is pulled out to the starting insertion position (the intersection of the planned closed eye end and the main rope), the strand 3 is reversely braided into the rope from the free end of the rope head along the empty path left after the strand 3 is pulled out;

[0013] S4: After the strand 3 is re-woven, the strand 1 is pulled out, and then the strand 1 is woven into the rope in the reverse direction along the path of the strand 5. At the same time, the strand 5 is pulled out and woven into the rope in the reverse direction along the path of the strand 1 to replace the original strand 1.

[0014] S5: After the replacement of strands 1, 3 and 5 is completed in sequence, the rope is turned 180 degrees, and the operations of steps S2-S4 are repeated to replace strands 2, 4 and 6. Strands 4 are pulled out and braided into the rope in the reverse direction along the path of the original strands 4, and strands 2 and 6 are pulled out and their positions are swapped;

[0015] S6: After the three strands in the Z direction (strand 1, strand 3 and strand 5) and the three strands in the S direction (strand 2, strand 4 and strand 6) are reversely inserted according to the method of steps S1-S5, enter the finishing process. Finally, subtract about 2 / 3 of the yarn from the head of each strand that has been leaked and insert them into the main rope according to the strand direction.

[0016] As a further description of the above technical solution: in step S6, the biological ends of the three strands in the Z direction and the three strands in the S direction are respectively wrapped tightly with tape; the ends of the remaining six strands that have not been plugged in and adapted are wrapped together with tape.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0018] Compared with the traditional method of splicing twelve-strand ropes, the present invention has a simple manufacturing process when splicing twelve-strand ropes, and the number of strands in the splicing section is still 12, so that the diameter of the splicing section is not much different from the diameter of the original rope. The pipa head is relatively small, so that it can adapt to working conditions with aperture requirements and meet the passing requirements. It has strong applicability, so that the appearance of the twelve-strand rope formed after splicing is more beautiful, and raw materials are saved, the structural integrity and mechanical properties of the twelve-strand rope are guaranteed, and each rope strand in the splicing section is more evenly stressed, thereby increasing the maximum bearing load, being firm, reliable, safe and durable, and being conducive to increasing its service life.
