Description

Technical Field

[0001] This utility model relates to the field of insulated pull wire technology, and in particular to an insulated pull wire. Background Technology

[0002] In power transmission systems, the stability of utility poles is crucial, and insulated guy wires are widely used as components to enhance the stability of utility poles.

[0003] Existing insulated guy wires have several problems. Their insulation relies solely on the outer insulation layer, which is difficult to maintain in harsh environments. Damage to the outer insulation layer leads to a decrease in insulation performance when the guy wire comes into contact with water. Furthermore, the connection structures at both ends of existing insulated guy wires are not convenient or efficient, affecting installation and maintenance. Therefore, this invention proposes an insulated guy wire to address these shortcomings. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide an insulated pull cord. By adding a water-repellent solvent to the insulating rope and covering the outside of the insulating rope with an abrasion-resistant insulating layer, the abrasion-resistant insulating layer can serve as the first insulating barrier. When the abrasion-resistant insulating layer is damaged, the insulating rope can form a second insulating barrier through the internal water-repellent solvent. The water-repellent solvent will block water and prevent water from seeping into the insulating rope, thus ensuring the insulation performance of the insulating rope.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An insulated guy wire includes an insulating rope, a wear-resistant insulating layer, a first casting joint, a second casting joint, an upper pull head, and a lower pull head. The insulating rope contains a water-repellent solvent. The insulating rope has a first casting joint and a second casting joint at both ends, respectively. The first and second casting joints are integrally formed by cold casting with both ends of the insulating rope. The outer walls of both the first and second casting joints are symmetrically provided with stepped grooves. The insulating rope is covered with a wear-resistant insulating layer. The upper pull head is detachably connected to the first casting joint, and the lower pull head is detachably connected to the second casting joint. The insulating rope is connected to a connection point on a utility pole via the upper pull head. A chain is detachably connected to the lower pull head of the insulating rope, and one end of the chain is connected to a ground anchor.

[0006] A further improvement is that the first and second casting joints have the same structure, both including a frustum and a connecting column. The connecting column is provided at one end of the frustum, and the outer wall of the connecting column is provided with external threads.

[0007] A further improvement is that the pull-up head includes a first cylindrical base, a first mating screw hole, and a first connecting piece. One end of the first cylindrical base is provided with the first mating screw hole, and the connecting column of the first casting joint is connected to the first mating screw hole through the external thread on the outer wall. The other end of the first cylindrical base is provided with the first connecting piece.

[0008] A further improvement is that the first connecting piece is provided with a fixing hole, and the upper pull head is connected to the connection point on the utility pole through a fixing bolt at the fixing hole.

[0009] A further improvement is that the pull-down head includes a second cylindrical base, a second docking screw hole, and a second connecting piece. One end of the second cylindrical base is provided with a second docking screw hole, and the connecting column of the second casting joint is connected to the second docking screw hole through an external thread on its outer wall. The other end of the second cylindrical base is provided with symmetrically arranged second connecting pieces.

[0010] A further improvement is that a connecting groove is formed between the two second connecting pieces, a locking hole is provided on the second connecting piece, a locking bolt is connected in the two locking holes, and a nut is provided at one end of the locking bolt.

[0011] The beneficial effects of this utility model are as follows: This utility model adds a water-repellent solvent inside the insulating rope and covers the outside of the insulating rope with a wear-resistant insulating layer. The wear-resistant insulating layer can serve as the first insulating barrier. When the wear-resistant insulating layer is damaged, the insulating rope can form a second insulating barrier through the internal water-repellent solvent. The water-repellent solvent will block water and prevent water from seeping into the insulating rope, thus ensuring the insulation performance of the insulating rope. In this utility model, the insulating rope has a first casting joint and a second casting joint formed by cold casting at both ends.

When the formed rope is connected to the upper pull head 5 and the lower pull head 6, it is done by connecting the first mating screw hole 502 on the upper pull head 5 to the external thread 11 on the connecting post 10 of the first casting joint 3. Similarly, the second mating screw hole 602 on the lower pull head 6 is connected to the external thread 11 on the connecting post 10 of the second casting joint 4. At this time, the entire insulated guy wire is assembled. Then, the upper pull head 5 is connected to the connection point on the utility pole, and a chain 8 is connected and fixed on the lower pull head 6. Finally, one end of the chain 8 is connected to the ground anchor.

[0017] The first casting joint 3 and the second casting joint 4 have the same structure, both including a frustum 9 and a connecting column 10. The connecting column 10 is located at one end of the frustum 9, and the outer wall of the connecting column 10 is provided with external threads 11.

Then the end that comes out is locked with a nut 606.

[0020] This invention incorporates a water-repellent solvent into the insulating rope 1 and covers the outside of the insulating rope 1 with a wear-resistant insulating layer 2. The wear-resistant insulating layer 2 serves as the first insulating barrier. When the wear-resistant insulating layer 2 is damaged, the insulating rope 1 can form a second insulating barrier through the internal water-repellent solvent. The water-repellent solvent blocks water and prevents water from seeping into the insulating rope 1, thus ensuring the insulation performance of the insulating rope 1. In this invention, the two ends of the insulating rope 1 are integrally formed by cold casting, with a first casting joint 3 and a second casting joint 4. The first casting joint 3 is connected to the upper pull head 5, and the second casting joint 4 is connected to the lower pull head 6 by threads, which has the advantage of convenient assembly and disassembly.
