Description

Technical Field

[0001] This invention relates to the field of power tools, and in particular to a method for calculating the force on a composite puller and a method for weaving a composite puller and insulating rope segments. Background Technology

[0002] Composite guy wires are crucial components in overhead power lines, used to balance pole tension, prevent pole tilting, and resist wind forces. They typically consist of a guy wire and a guy wire reel, with one end of the guy wire connected to the tower and the other end connected to the guy wire reel buried underground. Existing composite guy wire structures often use steel strands in conjunction with guy rods, relying on the interaction between the guy wire reel and the soil to provide pull-out resistance and maintain pole stability. While this method offers high mechanical strength, it still has several shortcomings in practical applications.

[0003] First, steel strands near the top of the tower are prone to becoming directly or indirectly energized due to contact with live parts, especially in rainy, snowy, or humid environments, posing a significant safety hazard and increasing the risk of electric shock. To address this issue, existing technologies often add guy wire insulators or flexible structures in the middle of the guy wire to achieve electrical isolation and improve safety. However, while these additional structures improve insulation performance, they may also affect the overall mechanical properties of the guy wire system.

[0004] Secondly, due to the high rigidity of the steel strands, workers need to perform a "reverse turning" operation during construction, which is time-consuming and labor-intensive, affecting construction efficiency. To improve installation convenience, flexible connecting components are often introduced into the structure, but this may also affect the stress state of the cable pulling system.

[0005] Currently, the design of composite guy wire pullers largely relies on empirical judgment or simplified estimation, lacking a systematic and quantitative stress calculation model. This makes it difficult to accurately assess the load-bearing capacity of the guy wire puller under different geological conditions and structural improvements. In particular, the overall strength of the composite guy wire puller may change after the introduction of insulators or flexible structures, and there is currently no effective stress analysis method to support these structural improvements. Summary of the Invention

[0006] The purpose of this invention is to provide a method for calculating the stress on composite pull plates, which solves the problem of difficulty in assessing the stress on composite pull plates and makes it easier to assess the stress on composite pull plates.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a composite guy wire calculation method, comprising a guy wire reel and a guy wire, one end of the guy wire being fixed to the tower, the other end of the guy wire being fixed to the guy wire reel, and the guy wire reel being installed on the ground. The upward pull force acting on the guy wire foundation, For the calculated unit weight of soil, The angle between the string and the ground. The safety factor for pull-out stability is related to soil resistance. The uplift stability safety factor is related to the foundation's self-weight. for The volume of soil resisting uplift within the depth, Based on the upward angle, Based on its own weight, the pull-out stability of the tension cable must meet the following requirements. .

[0008] After adopting the above technical solution, the present invention has the following advantages: the pulling force F of the pull wire T It is the tension transmitted from the tower to the guy wire, and the angle between the guy wire and the ground. The effective component of the pull-out force is determined by the angle; changes in angle directly alter the stress state of the guy wire reel. Since the guy wire reel is buried underground, its pull-out resistance is closely related to the surrounding soil. Indicates the upward angle The volume of soil affected by the guy wire within the range. The soil's unit weight and the pull-out resistance of the soil to the guy wire are both determined by these factors. A higher unit weight results in a greater pull-out force on the same volume of soil, thus increasing the soil resistance safety factor. The reliability of the manifold's resistance is affected by factors such as fluctuations in soil properties and construction errors. Secondly, the weight of the manifold itself also plays a role. It is also one of the important factors in resisting upward pull; the greater the self-weight, the stronger the pull resistance, and the higher the foundation self-weight safety factor. To ensure the stability of the pull-out force provided by the weight of the drawbar itself, and to avoid instability due to insufficient weight. Based on the formula The calculation method can quantify and correlate the above-mentioned stress factors, providing clear quantitative calculation standards. Designers do not need to rely on empirical simplifications and can directly calculate the pull-out resistance based on geological parameters and structural dimensions, reducing repeated trial and error. Furthermore, in the case of structural improvements to composite tensioners, the angle of the tension lines can also be deduced using this formula. By ensuring that the installation method matches the stress state within a reasonable range of parameters, the structural strength and stability of the composite pull plate can be guaranteed.

[0009] Furthermore, The shorter side of the drawstring reel. For the long side of the pull reel, The angle between the plane of the pull rod and the vertical. For the calculation of the backfill soil, the upward angle is... Based on the critical depth of upward pull, when hour, ;when hour, .

[0010] By adopting the aforementioned technical solution, the geometric parameters and installation angle of the guy wire reel are introduced, enabling a more realistic simulation of the stress pattern of the guy wire reel in the soil. In particular, when the guy wire reel is installed at an angle, the extent of soil affected during its upward pull-out process changes accordingly. Furthermore, the upward pull-out angle and critical upward pull-out depth are introduced, directly linking structural parameters with geological parameters. The calculations more closely match the actual stress range of the soil, and at the same time, utilize... and The comparison distinguishes the differences in the pull-out resistance mechanism of soil in shallow and deep regions, making The calculations can adapt to diverse geological conditions and wire rod structures.

[0011] Furthermore, The shorter side of the drawstring reel. For the long side of the pull reel, The calculated internal friction angle of the soil is given when the guy wire is laid flat. And the angle between the string and the ground At that time, the horizontal stability of the guy wire must meet the following requirements. .

[0012] Using the aforementioned technical solution, for both flat-lay and small-angle guy wires, the horizontal external load and soil resistance are correlated through a safety factor K1, clarifying the critical conditions for horizontal stability and minimizing the shortcomings of fuzzy estimation of horizontal forces in traditional empirical design. The formula incorporates the soil's internal friction angle. By deeply coupling structural parameters such as the size of the guy wire reel with geological properties, the stability of the guy wire reel under horizontal tension can be directly calculated.

[0013] Furthermore, when the pull wire reel is placed at an angle and perpendicular to the pull wire... When the cable reel is laid flat .

[0014] Using the aforementioned technical solution, the installation angle of the pull wire reel The angle of the guy wire it is connected to Maintain a proper matching relationship: When the pull reel is placed at an angle and its force-bearing surface is perpendicular to the direction of the pull line, set... This ensures that the direction of force on the pull reel is aligned with the direction of the pull line tension, which helps to achieve uniform force transmission and reduces structural deformation caused by eccentric force. When the pull reel is laid flat, the setting... This design ensures the guy wire reel is parallel to the ground, facilitating installation. This angle not only simplifies the stress analysis model of the guy wire reel and improves calculation efficiency and accuracy, but also adapts to the needs of different installation methods, enhancing the versatility and applicability of the guy wire reel structure. This setting allows for a balance between ease of installation and reasonable stress distribution in traditional structures and improved structures incorporating insulators and flexible connections, providing theoretical support for the structural optimization and stability design of composite guy wire reels.

[0015] Furthermore, when the tower is straight, the aforementioned , When the tower is a suspension angle type or a tension type, the aforementioned , When the tower is an angle type, a terminal type, or a large span type, the aforementioned , .

[0016] The above technical solutions set corresponding upward stability safety factors according to different tower types, fully considering the stress differences of different types of towers, making the guy wire plate design more targeted and reasonable. It also provides a unified standard for safety assessment after introducing insulators, flexible connections and other structural improvements, which is conducive to the standardization of guy wire plate design and the convenience of engineering application.

[0017] Furthermore, when the soil is clay or silty clay, , , When the soil is sandy, , , .

[0018] The above technical solution fully considers the differences in physical and mechanical properties of different types of soil. Based on different soil types, reasonable values ​​for soil unit weight, uplift angle, and internal friction angle are defined, which can more accurately reflect their impact on the pull-out resistance of the guy wire and increase the volume of the pull-out resistant soil. And the accuracy of pull-out force calculation.

[0019] Furthermore, The maximum tensile force that the guy wire can withstand. The long side of the draw reel. The shorter side of the drawstring reel. The depth of the cable reel. The strength utilization rate of the guy wire reel is the stress that the guy wire foundation can withstand. .

[0020] Through the above technical solutions, based on the geometric parameters and stress conditions of the drawstring spool, the strength assessment is refined, the utilization rate of the drawstring spool's strength is clarified, and material waste caused by over-design or safety hazards caused by under-design are avoided. At the same time, it provides a quantitative basis for the optimization of the drawstring spool size.

[0021] Another object of the present invention is to provide a composite puller plate, wherein the strength of the composite puller plate meets the strength requirements of the composite puller plate stress calculation method described in the above technical solution. The composite puller plate includes a puller line and an insulated puller line reel. The puller line includes an insulated rope segment, a chain segment, a U-shaped adjuster segment and a puller bar connected in sequence. The other end of the insulated rope segment is used to connect to the puller line clamp on the tower. The other end of the puller bar is used to connect to the puller line reel. The insulated rope segment has a multi-strand rope cross-woven structure.

[0022] Through the above technical solutions, firstly, the use of insulated rope segments instead of traditional steel strands in the guy wire effectively avoids the risk of live guy wires, especially under harsh weather conditions such as dampness, rain, and snow, significantly improving the electrical safety of line operation and reducing the occurrence of electric shock accidents. Secondly, the use of insulated guy wire reels further blocks current conduction, and the use of U-shaped adjuster segments facilitates the adjustment of guy wire length, achieving more precise control of tension. The chain segment raises the insulated rope segment, preventing it from directly contacting the ground or approaching the ground environment, minimizing the risk of the insulated rope segment becoming damp and contaminated due to contact with the ground, thus reducing its insulation performance, and minimizing wear, corrosion, water absorption, and aging caused by long-term contact with the ground. Finally, the insulated rope segment adopts a multi-strand rope cross-woven structure, forming a denser and more uniform stress system with higher tensile strength, fatigue resistance, and structural stability, capable of withstanding complex loads during long-term operation.

[0023] Furthermore, a protective cover is installed on the outside of the chain segment, and a solar panel and an indicator light connected to the solar panel are mounted on the protective cover.

[0024] Through the above technical solutions, the protective cover can effectively isolate rainwater erosion, dust accumulation, and ultraviolet radiation, ensuring the service life of the chain segment. The indicator light serves as a safety warning, making it easy for pedestrians and vehicles to identify. The protective cover is equipped with a solar panel, which uses natural light to power the indicator light, realizing the local use of green energy and achieving a self-sufficient power supply mode for the indicator light without external power supply.

[0025] Another object of the present invention is to provide a method for weaving insulating rope segments for producing the insulating rope segments described in the above-mentioned technical solution. The method for weaving insulating rope segments includes the following steps: S1, arranging five ropes side by side from left to right; S2, taking the leftmost rope, pressing it over the two adjacent ropes, lifting it from under the next rope and placing it between the next rope and the remaining rope; S3, taking the rightmost rope, pressing it over the two adjacent ropes, lifting it from under the next rope and placing it between the next rope and the remaining rope; S4, repeating steps S2 and S3 until the insulating rope segment is produced.

[0026] Through the above technical solution, each rope strand forms multiple cross-interlocking with other rope strands during the weaving process. This retains the flexibility of a single rope strand, allowing the insulating rope segment to bend flexibly during construction. Under stress, the tension can be evenly distributed to all rope strands through the interlacing points, significantly improving the tensile and torsional resistance of the insulating rope segment. This better matches the high strength requirements of the composite pull plate, ensuring that it is not easily deformed or damaged when subjected to long-term tension, and minimizing the risk of single-strand breakage due to overload. The symmetrical operation of steps S2 and S3 forms a standardized process, eliminating the need for complex parameter adjustments. This facilitates worker mastery and mass production, and also ensures that the density and tightness of each insulating rope segment are consistent, avoiding performance fluctuations caused by process differences and ensuring the stable mechanical properties of mass-produced insulating rope segments.

[0039] Example 1:

[0040] like Figure 1 and Figure 2 As shown, the present invention provides a method for calculating the force of a composite guy wire, including a guy wire reel 11 and a guy wire. One end of the guy wire is fixed to the tower, and the other end of the guy wire is fixed to the guy wire reel 11. The guy wire reel 11 is installed on the ground 20. The upward pull force acting on the guy wire foundation, For the calculated unit weight of soil, The angle between the string and the ground is 20 degrees. The safety factor for pull-out stability is related to soil resistance. The uplift stability safety factor is related to the foundation's self-weight. for The volume of soil resisting uplift within the depth, Based on the upward angle, Based on its own weight, the pull-out stability of the tension cable must meet the following requirements. .

[0041] Pull-out force of the pull wire The tension is transmitted from the tower to the guy wire, and the guy wire is at a 20° angle to the ground. The effective component of the pull-out force is determined by the angle. Changes in angle directly alter the stress state of the guy wire reel 11. Since the guy wire reel 11 is buried underground, its pull-out resistance is closely related to the surrounding soil. Indicates the upward angle The volume of soil within the area affected by guy wire 11, The soil's unit weight and the soil's resistance to pull-out from the guy wire 11 are both factors that determine the soil's pull-out resistance. A higher unit weight results in a greater pull-out force for the same volume of soil, thus increasing the soil resistance safety factor. The reliability of soil resistance is affected by factors such as fluctuations in soil properties and construction errors. Secondly, the weight of the guy wire reel 11 itself... It is also one of the important factors in resisting upward pull; the greater the self-weight, the stronger the pull resistance, and the higher the foundation self-weight safety factor. To ensure the stability of the pull-out force provided by the weight of the draw reel 11, and to avoid instability due to insufficient weight. Based on the formula The calculation method can quantify and correlate the above-mentioned stress factors. With clear quantitative calculation standards, designers do not need to rely on empirical simplifications and can directly calculate the pull-out resistance based on geological parameters and structural dimensions, reducing repeated trial and error. At the same time, in the case of structural improvements to the composite pull plate, the formula can also be used to deduce the reasonable range of parameters such as the pull line angle ω, so as to ensure that the installation method matches the stress state as much as possible, thereby ensuring the structural strength and stability of the composite pull plate.

[0042] For example, based on the pit of the pre-embedded guy wire plate 11, the upward pull force F acting on the guy wire foundation T Calculated unit weight of soil Based on soil resistance, the safety factor for pull-out stability Uplift stability safety factor related to foundation self-weight , The volume of soil resisting uplift within the depth Basic upward angle and basic self-weight All of these can be directly measured based on the required tension of the tower, the dimensions of the guy wire reel 11 itself, and the installation depth, and the angle between the guy wire and the ground 20 can be calculated accordingly. .

[0043] Because the installation depth of the cable tray 11 varies, therefore, in this application, when hour, ;when hour, The geometric parameters and installation angle of the guy wire reel 11 are introduced to more realistically simulate the stress pattern of the guy wire reel 11 in the soil. Especially when the guy wire reel 11 is installed at an angle, the extent of soil affected during its upward pull-out process changes accordingly. Furthermore, the upward pull-out angle and critical upward pull-out depth are introduced to directly link structural parameters with geological parameters, making... The calculations more closely match the actual stress range of the soil, and at the same time, utilize... and The comparison distinguishes the differences in the pull-out resistance mechanism of soil in shallow and deep regions, making The calculations can adapt to diverse geological conditions and the structure of the guy wire 11.

[0044] in For the short side of the pull wire reel 11, For the long side of the pull reel 11, The angle between the upper plane of the pull-line reel 11 and the vertical. For the calculation of the backfill soil, the upward angle is... The critical depth for upward pull based on the base. The installation angle of the pull rod 11. The angle of the guy wire it is connected to Maintain a reasonable matching relationship: When the pull wire reel 11 is placed at an angle and its force-bearing surface is perpendicular to the pull wire direction, set... This ensures that the direction of force on the pull reel 11 is aligned with the direction of the pull line tension, which helps to achieve uniform force transmission and reduce structural deformation caused by eccentric force. When the pull reel 11 is laid flat, the setting... This arrangement ensures that the guy wire reel 11 is parallel to the ground 20, facilitating construction and installation. This angular relationship not only simplifies the force analysis model of the guy wire reel 11, improving calculation efficiency and accuracy, but also adapts to the needs of different installation methods, enhancing the versatility and applicability of the guy wire reel 11 structure. Through this setting, a balance between ease of installation and reasonable force distribution can be achieved in traditional structures and improved structures incorporating insulators and flexible connections, providing theoretical support for the structural optimization and stability design of composite guy wire reels.

[0045] Furthermore, horizontal stability: when the pull line reel 11 is laid flat. And the guy wire is at a 20° angle to the ground. At this time, it is necessary to verify the stability of the pull wire reel 11 in the horizontal direction, wherein the horizontal stability of the pull wire must meet the following requirements. For the horizontal placement and small-angle mandrel 11, the horizontal external load and soil resistance are considered using a safety factor. The correlation clarifies the critical conditions for horizontal stability, minimizing the shortcomings of "fuzzy estimation" of horizontal forces in traditional empirical design. The formula incorporates the soil's internal friction angle. By deeply coupling structural parameters such as the dimensions of the guy wire disc 11 with geological properties, the stability of the guy wire disc 11 under horizontal tension can be directly calculated. For example, sandy soil ( (Larger) passive earth pressure through tan 2 The item was enlarged, clay ( If the value is smaller, the calculated resistance value is automatically reduced, making the horizontal stability assessment under different geological conditions more realistic and solving the problem that traditional simplified models ignore soil type differences. The calculated internal friction angle of the soil.

[0046] Different types of towers experience significant differences in tension, load, and operating conditions. Therefore, this application focuses on straight towers subjected to relatively low stress. , When suspended angle towers or tension towers are subjected to large forces, , However, when the tower is a corner type, a terminal type, or a large span type, , The design of the guy wire spool 11 is more targeted and rational, taking into full account the stress differences of different types of towers. By setting safety factors in stages, the design balances structural safety with economic efficiency, improving the applicability and design efficiency of the composite guy wire spool. At the same time, this method also provides a unified standard for safety assessment after structural improvements such as the introduction of insulators and flexible connections, which is conducive to the standardization of composite guy wire spool design and the convenience of engineering applications.

[0047] Different types of soil exhibit significant differences in unit weight, shear strength, and angle of internal friction. Therefore, in this application, when the soil is clay or silty clay, , , When the soil is sandy, , , Taking full account of the differences in physical and mechanical properties of different types of soil, reasonable values ​​for soil unit weight, uplift angle, and internal friction angle were set according to different soil types. This allows for a more accurate reflection of their impact on the pull-out resistance of the guy wire 11, and increases the volume of the pull-out-resistant soil. And the accuracy of pull-out force calculation.

[0048] Preferably, when the clay or silty clay is hard, , , When clay or silty clay is a stiff plastic, , , When clay or silty clay is plastic, , , When clay or silty clay is soft plastic, , , When the sandy soil is gravelly, , , When the sand is coarse sand, , , When the sandy soil is medium sand, , , When the sand is fine sand, , , When the sand is silt, , , .

[0049] It should be noted that when buried in several different soil layers, their weighted average value can be used. The calculated capacity is below the groundwater level. Generally, the buoyant unit weight is used. However, for straight-line tower foundations of cohesive soil with a plasticity index greater than 10, the natural unit weight can be used.

[0050] It should be noted that "hard," "stiff plastic," "plastic," and "soft plastic" are professional terms in the fields of soil mechanics and engineering geology, mainly used to describe the physical state or consistency of clay or silty clay, based on the soil's water content (w) and limiting water content (liquid limit). Plastic Limit The classification is based on the relationship between plasticity index and other plasticity index. Liquidity index To make a judgment.

[0051] It should be noted that gravelly sand, coarse sand, medium sand, fine sand, and silty sand are professional terms in the fields of soil mechanics and engineering geology. They are mainly used to describe the particle size distribution of sandy soil and are classified according to the particle size of the sandy soil particles.

[0052] To calculate the strength utilization rate of the wire puller 11 Based on the geometric parameters and stress conditions of the drawstring 11, the strength assessment was refined, the utilization rate of the drawstring 11 strength was clarified, and material waste caused by over-design or safety hazards caused by under-design were avoided. At the same time, a quantitative basis was provided for the size optimization of the drawstring 11.

[0053] in, The maximum tensile force that the guy wire can withstand. For the depth of the pull reel 11, This refers to the stress that the guy wire foundation can withstand.

[0054] Example 2:

[0055] like Figure 3 As shown, this embodiment discloses a composite puller, which includes a pull line 10 and an insulated pull line reel 11. The pull line 10 includes an insulated rope segment 101, a chain segment 102, a U-shaped adjuster segment 103, and a pull line bar 104 connected in sequence. The other end of the insulated rope segment 101 is used to connect to the pull line 10 clamp on the tower, and the other end of the pull line bar 104 is used to connect to the insulated pull line reel 11. The insulated rope segment 101 has a multi-strand rope cross-woven structure.

[0056] First, the guy wire 10 uses insulated rope segment 101 instead of traditional steel strand, which effectively avoids the risk of the guy wire 10 being electrified. Especially under harsh weather conditions such as dampness, rain and snow, it can significantly improve the electrical safety of the line operation and reduce the occurrence of electric shock accidents. When used in power distribution networks, it is easy to adjust the safe distance from electrical parts, making the installation flexible and convenient, which is incomparable to traditional metal guy wire 10. Secondly, the use of an insulated pull reel 11 further blocks the conduction of current. Additionally, the use of a U-shaped adjuster section 103 facilitates the adjustment of the pull wire 10 length, enabling more precise control of the tension. The chain section 102 elevates the insulated rope section 101, preventing it from directly contacting or approaching the ground 20 environment. This minimizes the risk of the insulated rope section 101 becoming damp or contaminated due to contact with the ground 20, reducing its insulation performance, and also minimizes wear, corrosion, and water absorption aging caused by long-term contact with the ground 20. Finally, the insulated rope section 101 employs a multi-strand rope cross-woven structure, forming a denser and more uniform stress system with higher tensile strength, fatigue resistance, and structural stability, enabling it to withstand complex loads during long-term operation.

[0057] The strength of the composite pull plate meets the strength requirements of the composite pull plate force calculation method in Example 1.

[0058] Insulating rope segment 101 is an insulating material. Insulating rope segment 101 is woven using a circular five-strand braiding method. The outer layer of insulating rope segment 101 is covered with an orange flexible insulating layer to prevent moisture from entering the insulating rope body, causing the originally insulating insulating rope segment 101 to become a conductor and affecting its insulation performance.

[0059] The insulating rope segment 101 has a connecting hardware 105 at each end, eliminating the laborious process of rewiring the traditional steel guy wire 10 on-site, allowing for quick connection and installation, saving labor and effort. The end of the insulating rope segment 101 passes through the connecting hardware 105, and is cured into the interior of the connecting hardware 105 using a curing adhesive, thus connecting the connecting hardware 105 to the insulating rope. Simultaneously, the curing adhesive completely seals the insulating rope segment 101, making it an integral part of the connecting hardware 105. This prevents moisture from entering the insulating rope segment 101 through the connecting hardware 105, affecting its insulation performance. The insulating rope segment 101 is connected to the guy wire 10 clamp on the pole via the connecting hardware 105, and the other end is bolted to the chain segment 102. The chain segment 102 is bolted through the U-shaped adjuster hole and the chain hole, connecting them together.

[0060] The use of the U-shaped adjuster makes it easy to tighten the insulating rope segment 101 and adjust its tension. The insulating pull reel 11 is made of composite material, which is lightweight, relatively simple to manufacture, easy to transport, and has high strength.

[0061] The chain segment 102 is equipped with a protective cover, which can effectively isolate rainwater erosion, dust accumulation and ultraviolet radiation, ensuring the service life of the chain segment 102. The protective cover is equipped with an indicator light, which serves as a safety warning and facilitates identification by pedestrians and vehicles. The protective cover is also equipped with a solar panel connected to the lifting light, which uses natural light to power the indicator light, realizing the local use of green energy and achieving a self-sufficient power supply mode for the indicator light without external power supply.

[0062] Chain segment 102 is constructed using a ring chain connection. The indicator light is a light strip; during the day, the solar panel charges, and the light strip remains off. At night, when the solar panel stops charging, the light strip automatically illuminates, facilitating pedestrian and vehicle identification. The light is a constant warm yellow glow, and its brightness is adjustable to suit different site conditions.

[0063] Example 3:

[0064] like Figure 4 As shown, this embodiment discloses a method for weaving an insulating rope segment 101, used to produce the insulating rope segment 101 of the above-mentioned technical solution. The method for weaving the insulating rope segment 101 includes the following steps: S1, arranging five ropes side by side from left to right; S2, taking the leftmost rope, pressing it over the two adjacent ropes, lifting it from under the next rope and placing it between the next rope and the remaining rope; S3, taking the rightmost rope, pressing it over the two adjacent ropes, lifting it from under the next rope and placing it between the next rope and the remaining rope; S4, repeating steps S2 and S3 until the insulating rope segment 101 is produced.

[0065] Each strand of rope undergoes multiple cross-interlocking processes with other ropes during weaving. This preserves the flexibility of a single strand, allowing the insulating rope segment 101 to bend flexibly during construction. Under stress, the tension is evenly distributed to all strands through the interlacing points, significantly improving the tensile and torsional resistance of the insulating rope segment 101. This better matches the high-strength requirements of the composite pull plate, ensuring that it is not easily deformed or damaged when subjected to the tension of the pull wire 10 for a long time, and minimizing the risk of single-strand breakage due to overload. The symmetrical operation of steps S2 and S3 forms a standardized process, eliminating the need for complex parameter adjustments. This facilitates worker mastery and mass production, and also ensures that the density and tightness of each insulating rope segment 101 are consistent, avoiding performance fluctuations caused by process differences and ensuring the stable mechanical properties of the mass-produced insulating rope segment 101.

[0066] For easy differentiation, the five ropes S1 are numbered from left to right as Rope No. 1 1011, Rope No. 2 1012, Rope No. 3 1013, Rope No. 4 1014 and Rope No. 5 1015, with each rope having the same thickness.

[0067] S2. Use the leftmost rope 1011 to pass over the right ropes 2012 and 3013. At this point, ropes 4014 and 5015 are to the right of rope 1011. Then, lift rope 1011 up from under rope 4014 and bring it between ropes 4014 and 5015. The sequence of the insulating rope segments 101 is now: rope 2012, rope 3013, rope 4014, rope 1011, and rope 5015.

[0068] S3. Using the rightmost rope, No. 5 (1015), pass over ropes No. 1 (1011) and No. 4 (1014). At this point, ropes No. 3 (1013) and No. 2 (1012) are to the left of rope No. 5 (1015). Then, lift rope No. 5 (1015) from under rope No. 3 (1013) and place it between ropes No. 2 (1012) and No. 3 (1013). The sequence of the insulating rope segments 101 is now: rope No. 2 (1012), rope No. 5 (1015), rope No. 3 (1013), rope No. 4 (1014), and rope No. 1 (1011).

[0069] The weaving sequence is as shown in steps S2 and S3, always starting from the side ropes and repeating in this cycle. For example, repeating step S2 again would involve rope number 2 (1012) on the left, passing over rope number 5 (1015) and rope number 3 (1013), then lifting up from under rope number 4 (1014), finally ending between rope number 4 (1014) and rope number 1 (1011). At this point, the sequence of the insulating rope segments 101 is: rope number 5 (1015), rope number 3 (1013), rope number 4 (1014), rope number 2 (1012), and rope number 1 (1011).
