Abstract
Description
Technical Field
[0001] This utility model belongs to the field of special rope technology, specifically relating to a multi-layer composite intertwined high-temperature tungsten wire rope, which is suitable for special environments requiring high temperature and high strength. Background Technology
[0002] In fields such as metallurgy, semiconductor manufacturing, and aerospace, traditional steel wire ropes or synthetic fiber ropes are prone to failure in high-temperature environments, failing to meet the demands of extreme working conditions. Existing metal ropes mostly use stainless steel or other alloy materials, but these materials experience problems such as strength reduction and oxidation in high-temperature environments above 1600℃.
[0003] Tungsten, due to its high melting point (3422℃) and excellent mechanical properties, is an ideal material for high-temperature applications. However, pure tungsten wire is brittle and difficult to directly fabricate into ropes. Currently, no specific weaving process has been found to combine multiple strands of tungsten wire into a rope structure that combines flexibility and strength. Utility Model Content
[0004] The technical problem solved by this utility model is to provide a multi-layer composite intertwisted high-temperature tungsten wire rope. The purpose of this utility model is to provide a high-temperature resistant and high-strength tungsten wire rope, which solves the problem of insufficient performance of existing ropes in extreme environments.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A multi-layer composite intertwined high-temperature tungsten wire rope, wherein the tungsten wire rope adopts a 61×7 structure, that is, the rope body is composed of 61 single strands, each single strand is composed of 7 single wires, for a total of 427 single wires; its structure consists of a central rope and an outer layer rope.
[0007] The central rope consists of 7 central single ropes, with one central single rope placed in the center and the other 6 central single ropes evenly wrapped around the central single rope in the center position.
[0008] Each central single rope consists of 7 central single strands, with one central single strand placed in the center and the other 6 central single strands evenly wrapped around the central single strand in the center; each central single strand consists of 7 central single filaments, with one central single filament placed in the center and the other 6 central single filaments evenly wrapped around the central single filament in the center.
[0009] The outer rope consists of 12 outer strands, which are evenly wrapped around the central rope. Each outer strand consists of 7 outer monofilaments, with one outer monofilament placed in the center and the other 6 outer monofilaments evenly wrapped around the outer monofilament in the center.
[0010] Further specifying the above scheme, the diameter of the central monofilament is 0.12-0.15 mm, and the diameter of the outer monofilament is 0.33-0.36 mm.
[0011] Further defining the above scheme, the diameter of the central monofilament is 0.13 mm, and the diameter of the outer monofilament is 0.35 mm.
[0012] To further define the above scheme, both the central monofilament and the outer monofilament are made of 99.95% scheelite.
[0013] Further specifying the above scheme, the diameter of the tungsten wire rope is in the range of φ0.3mm-φ8.0mm.
[0014] As a further specification of the above scheme, the center rope and the outer rope are woven using a reverse twisting process.
[0015] Advantages of this utility model compared to the prior art:
[0016] 1. This solution has excellent high temperature resistance and can work for a long time in environments above 1600℃, transmit long-distance loads, and withstand complex loads;
[0017] 2. This solution adjusts the structure, changing the original 19x7 133 single wires of the tungsten wire rope to a new structure of 427 single wires, increasing the overall tensile strength by 5%; reducing the counterweight requirement by 11% under the same axial radius, improving the crystal pulling success rate, and significantly improving the stability of constant diameter growth.
[0018] 3. The diameter of the outer contact wire in this solution remains consistent with the original 19x7, ensuring sufficient wear resistance of the product, avoiding the problems of fuzzing and wire breakage caused by the thinness of the outer single filament, and improving service life;
[0019] 4. In this solution, the central strand of the tungsten wire rope is made thinner and more tightly wound, with a structure that is close to a centrally compacted strand. This reduces the rope's elongation and diameter reduction ratio during use, thereby improving the overall service life of the rope.
[0020] 5. This solution has excellent fatigue resistance, the reverse twisting process extends service life, the structure is stable, the performance does not decrease under high-speed conditions, and it is suitable for harsh environments such as the ocean.
[0021] 6. This solution is flexible, easy to install and use; it is lightweight, making it easy to transport and operate. Attached Figure Description

[0025] Please see Figure 1 The embodiments of this utility model are described in detail below.
[0026] See Figure 1 As shown in the figure, this embodiment provides a multi-layer composite intertwined high-temperature tungsten wire rope. The tungsten wire rope adopts a 61×7 structure, that is, the rope body is composed of 61 single strands, each single strand is composed of 7 single wires, and a total of 427 single wires.
[0027] The tungsten wire rope structure consists of a central rope 1 and an outer rope 2.
[0028] The central rope 1 consists of 7 central single ropes 1-1, with one central single rope 1-1 positioned in the center and the remaining 6 central single ropes 1-1 evenly wrapped around the central single rope 1-1 in the center position, forming a 1+6 structure arrangement. Each central single rope 1-1 consists of 7 central single strands 1-1-1, with one central single strand 1-1-1 positioned in the center and the remaining 6 central single strands 1-1-1 evenly wrapped around the central single strand 1-1-1 in the center position, also using a 1+6 structure arrangement; each central single strand 1-1-1 consists of 7 central single filaments 1-1-1-1, with one central single filament 1-1-1-1 positioned in the center and the remaining 6 central single filaments 1-1-1-1 evenly wrapped around the central single filament 1-1-1-1 in the center position, also using a 1+6 structure arrangement.
[0029] The outer rope 2 consists of 12 outer single strands 2-1, which are evenly wrapped around the central rope 1. Each outer single strand 2-1 consists of 7 outer single filaments 2-1-1, with one outer single filament 2-1-1 placed in the center position and the remaining 6 outer single filaments 2-1-1 evenly wrapped around the outer single filament 2-1-1 in the center position, also using a 1+6 structure arrangement.
[0030] The diameter of the central monofilament 1-1-1-1 is 0.12-0.15 mm, and the diameter of the outer monofilament 2-1-1 is 0.33-0.36 mm.
[0031] Preferably, the diameter of the central monofilament 1-1-1-1 is 0.13 mm, and the diameter of the outer monofilament 2-1-1 is 0.35 mm.
[0032] Preferably, both the central monofilament 1-1-1-1 and the outer monofilament 2-1-1 are made of 99.95% scheelite.
[0033] Preferably, the diameter of the tungsten wire rope is in the range of φ0.3mm-φ8.0mm.
[0034] This tungsten wire rope achieves a balance between high strength and flexibility through a specific weaving process. Specifically, the weaving process employs a reverse twisting technique:
[0035] Rope center strand: Twist direction: Reverse twist
[0036] Rope center strand outer strand: Twist direction: Positive intertwine
[0037] Rope body center strand outer strand center strand: Twist direction: Positive intertwine
[0038] Rope center strand outer strand: Twist direction: Reverse twist
[0039] Outer rope layer: Twist direction: Reverse twist
[0040] Rope center strand: Twist direction: Counter-twist
[0041] Rope center strands: Twist direction: Positive intertwine
[0042] Center rope formation: Twist direction: Reverse twist
[0043] Outer layer rope: Twist direction: Positive intertwine.
[0044] The compression parameters of the center rope are 3.27, and the compression parameters of the outer rope are 5.27.
[0045] This invention achieves uniform load distribution through a multi-layer 1+6 structural design. The central rope provides the main tensile strength, while the outer ropes provide abrasion protection and auxiliary load-bearing capacity. The reverse twisting process eliminates internal stress and improves the rope's fatigue life. The combination of monofilaments of different diameters optimizes the balance between flexibility and strength, resulting in high tensile strength, fatigue strength, and impact toughness, thus solving the problem of insufficient performance of existing ropes in extreme environments.
