Description

Technical Field

[0001] This utility model relates to the field of power transmission and communication technology, and more specifically, it relates to a multi-stranded conductor core. Background Technology

[0002] In the fields of power transmission and communication, in order to meet the requirements of high-intensity, long-distance and stable transmission, multiple conductor cores are often twisted together to form a single unit. This multi-strand conductor core is usually made of conductors of various specifications, such as central core, thin core and thick core, twisted together in a specific arrangement to form a conductor core with a multi-layer structure. However, since the twisted conductor core contains conductors of different thicknesses and materials, the stress and fixing requirements of each part at the connection point are significantly different. Therefore, how to fix the twisted conductor core firmly and efficiently, especially to quickly complete the fixing during assembly and connection, is a challenge. In traditional technology, the fixing of the two ends of the conductor core often relies on manual operation or complex clamping structures. This not only affects the efficiency of operation, but also easily leads to loosening or damage to the conductor due to uneven force.

[0003] In practical applications, the fixing and assembly of the two ends of the conductor core rod usually requires quick, efficient, and stable operation, especially in situations where frequent replacement, maintenance, or adjustment is required. However, in existing technologies, fixing devices for multi-strand conductor core rods often lack targeted design and cannot adapt to the characteristics of different thicknesses of core rods in stranded structures, which can easily lead to problems such as insecure fixing or damage to the conductor. At the same time, traditional fixing methods usually require multiple steps to complete the installation, which is time-consuming and complex, and is not conducive to rapid deployment and maintenance in actual engineering. The existence of these problems seriously affects the stability and ease of operation of the conductor core rod in actual use. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a multi-strand conductor core rod, which solves the technical problem mentioned in the background art that the fixing device for multi-strand conductor core rods often lacks a targeted design and cannot adapt to the different thicknesses of core rods in the stranded structure.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-stranded conductor core rod, comprising a stranded structure, wherein the stranded structure includes a central rod, thin rods, and thick rods, wherein the thin rods are arranged in multiple sets concentrically stranded outside the central rod, and the thick rods are arranged in multiple sets concentrically stranded outside the multiple sets of thin rods. Both ends of the stranded structure are provided with fixing mechanisms, wherein the fixing mechanisms include a fixing sleeve, push rods, clamping plates, pressure plates, pressure sleeves, rotating sleeves, external threaded sleeves, and a locking mechanism. The fixing sleeves are disposed outside the thick carbon fiber rods, the push rods are arranged in multiple sets sliding on the outer wall of the fixing sleeves, the clamping plates are installed at the bottom ends of the multiple sets of push rods, the pressure plates are arranged in multiple sets rotatably mounted on the outer wall of the fixing sleeves, the pressure sleeves slide on the outer wall of the fixing sleeves, the rotating sleeves are rotatably mounted on the outer wall of the fixing sleeves, and the external threaded sleeves are installed on the bottom surface of the rotating sleeves and threadedly connected to the outer wall of the pressure sleeves.

[0008] The present invention is further provided that the outer wall of the fixed sleeve is provided with guide strips, and multiple sets of guide strips are provided and slidably connected with the pressure sleeve. The guide strips ensure the stability and accuracy of the movement of the pressure sleeve, effectively prevent the pressure sleeve from deviating during the movement, and improve the smoothness and stability of the device operation.

[0009] The present invention is further configured such that each of the multiple sets of push rods has a stop block at its top, and the top surface of each of the multiple sets of stop blocks is a circular arc surface. The circular arc surface design makes the thrust more evenly distributed, reduces local stress concentration, protects the connected parts, and improves the stability of the contact and the efficiency of operation.

[0010] The present invention is further configured such that each of the multiple sets of clamping plates is equipped with a sliding rod, and each set of clamping plates is provided with two sets of sliding rods. The multiple sets of sliding rods are slidably connected to the fixed sleeve. The sliding rod guiding structure makes the movement of the clamping plates more precise and stable, effectively preventing the clamping plates from tilting or jamming, and improving the reliability of the clamping operation.

[0011] The present invention is further configured such that each of the multiple sets of sliding rods is provided with a contraction spring on its outer wall, and the two ends of the multiple sets of contraction springs are respectively connected to the inner wall of the fixing sleeve and the outer side of the multiple sets of clamping plates. The contraction springs provide an elastic reset function to ensure that the clamping plates can quickly return to the initial position, simplify the operation process, and improve the automation level and operation efficiency of the device.

[0012] The present invention is further provided that a reset spring is connected between the inner wall of the multiple sets of pressure plates and the fixed sleeve. The design of the reset spring enables the pressure plates to automatically reset, reducing the need for manual adjustment and improving the convenience of operation and the working efficiency of the device.

[0013] The present invention is further provided with soft pads on the inner side of multiple sets of clamping plates. The soft pads are provided in multiple sets. The soft pads effectively prevent wear or damage to the surface of the parts during clamping, while improving the stability of clamping and ensuring safe and reliable operation.

[0014] The present invention is further configured such that the locking mechanism includes a locking groove, a locking block, a tension spring, a locking sleeve, a push spring, and a limiting rod. Multiple sets of locking grooves are distributed on the outer wall of the fixed sleeve. Multiple sets of locking blocks slide on the rotating sleeve. The tension springs are installed on the tops of the multiple sets of locking blocks and connected to the outer wall of the rotating sleeve. The locking sleeve slides on the outer wall of the fixed sleeve. Multiple sets of push springs are provided, with their two ends respectively connected to the top surfaces of the fixed sleeve and the locking sleeve. Multiple sets of limiting rods are installed on the fixed sleeve and slidably connected to the locking sleeve, thereby effectively limiting the rotation of the sleeve, ensuring stable connection of all components after the fixing operation is completed, and preventing loosening during use.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a multi-stranded conductor core rod, which has the following beneficial effects:

[0017] 1. The stranded structure adopts a multi-layer concentric stranded design of a center rod, thin rods, and thick rods. By evenly stranding multiple sets of thin rods on the outside of the center rod, and then stranding thick rods on the outside of the thin rods, a tight and stable multi-layered structure is formed. This design allows the conductor core to maintain high conductivity while effectively improving its tensile strength and torsional resistance. At the same time, the evenly distributed stranded structure also enhances the durability and flexibility of the conductor core, providing a stable foundation for fixed operation.

[0018] 2. The fixing mechanism, through the coordinated design of a fixed sleeve, push rod, clamping plate, pressure plate, pressure sleeve, rotating sleeve, external threaded sleeve, and a series of auxiliary components, achieves a fast and stable fixing operation. When the pressure sleeve slides along the guide bar driven by the external threaded sleeve, it pushes the pressure plate to rotate along the outer wall of the fixed sleeve, while simultaneously squeezing the return spring. The downward pressure of the pressure plate is transmitted to the push rod through the abutment block, which further pushes the clamping plate to achieve clamping. The inner side of the clamping plate is equipped with a soft pad, which effectively protects the outer surface of the thick rod from damage through flexible contact. At the same time, under the action of the contraction spring, the clamping plate can be flexibly adjusted to ensure uniform and stable clamping force. This fixing method significantly improves the operating efficiency, can quickly complete the fixing of multi-layer stranded wire core rods, and has good stability, avoiding the loosening or displacement of the wire under external force.

[0019] 3. The locking mechanism consists of a locking groove, a locking block, a tension spring, a locking sleeve, a push spring, and a limiting rod. The push spring pushes the locking sleeve to slide against the locking block, causing the bottom end of the locking block to embed into the locking groove, thereby effectively limiting the rotation of the sleeve. This ensures the stable connection of all components after the fixing operation is completed and prevents loosening during use. When unlocking is required, the locking sleeve is slid upward to release the limiting effect of the locking block. Under the tension of the tension spring, the locking block quickly disengages from the locking groove, allowing the rotation of the sleeve to rotate freely and complete the unlocking operation. This design not only ensures the safety and reliability of the fixing mechanism but also simplifies and simplifies the locking and unlocking process through the reasonable design of elastic components, further improving the overall ease of use of the device.

[0029] Please see Figures 1-5 A multi-stranded conductor core rod includes a stranded structure 1. The stranded structure 1 includes a central rod 2, thin rods 3, and thick rods 4. The thin rods 3 are arranged in multiple sets of concentric strands outside the central rod 2, and the thick rods 4 are arranged in multiple sets of concentric strands outside the multiple sets of thin rods 3. Both ends of the stranded structure 1 are provided with fixing mechanisms. The fixing mechanisms include a fixing sleeve 5, a push rod 6, a clamping plate 7, a pressure plate 8, a pressure sleeve 9, a rotating sleeve 10, an external threaded sleeve 11, and a locking mechanism. The fixing sleeve 5 is located outside the thick carbon fiber rod. The push rod 6 is arranged in multiple sets of sliding on the outer wall of the fixing sleeve 5. The clamping plate 7 is installed at the bottom end of the multiple sets of push rods 6. The pressure plate 8 is arranged in multiple sets of rotating installations on the outer wall of the fixing sleeve 5. The pressure sleeve 9 slides on the outer wall of the fixing sleeve 5. The rotating sleeve 10 is rotatably installed on the outer wall of the fixing sleeve 5. The external threaded sleeve 11 is installed on the bottom surface of the rotating sleeve 10 and is threadedly connected to the outer wall of the pressure sleeve 9.

[0030] The outer wall of the fixed sleeve 5 is provided with guide strips 12. Multiple sets of guide strips 12 are provided and are slidably connected to the pressure sleeve 9, so that the pressure sleeve 9 can move smoothly along the guide strips 12, thereby driving the pressure plate 8 to achieve the corresponding operation.

[0031] Each of the multiple push rods 6 has a stop block 13 at its top. The top surface of each of the multiple stop blocks 13 is set as an arc surface, which can flexibly contact other components when subjected to pressure, avoiding excessive friction or damage to other components.

[0032] Each set of clamping plates 7 is equipped with a sliding rod 14. Each set of clamping plates 7 is provided with two sets of sliding rods 14. All sets of sliding rods 14 are slidably connected to the fixed sleeve 5, so that the clamping plates 7 can move smoothly under the guidance of the sliding rods, and realize the function of clamping or releasing.

[0033] Multiple sets of slide rods 14 are equipped with contraction springs 15 on their outer walls. The two ends of the multiple sets of contraction springs 15 are respectively connected to the inner wall of the fixing sleeve 5 and the outer side of the multiple sets of clamping plates 7. The contraction springs 15 provide elastic reset function to ensure that the clamping plates 7 can quickly return to the initial position, simplify the operation process, and improve the automation level and operation efficiency of the device.

[0034] Each of the multiple pressure plates 8 has a return spring 16 connected between its inner wall and the fixed sleeve 5. After the pressure plate 8 completes the clamping operation, the return spring 16 can provide elastic restoring force to return the pressure plate 8 to its original position.

[0035] Multiple sets of clamping plates 7 are provided with soft pads 17 on their inner sides. There are multiple sets of soft pads 17. When the soft pads 17 come into contact with the clamped parts, they can play a flexible buffering and protection role.

[0036] In this embodiment, the twisted structure 1 consists of a central rod 2, thin rods 3, and thick rods 4. These rods are twisted together concentrically. The thin rods 3 are divided into multiple groups and are concentrically twisted around the outer layer of the central rod 2. The thick rods 4 are twisted around the outer layer of the thin rods 3, forming a multi-layer twisted structure. The fixing sleeve 5 is fitted onto the thick rods 4 on the outer layer of the twisted structure 1 to ensure that the fixing mechanism and the conductor core are aligned. Rotating the rotating sleeve 10 drives the outer threaded sleeve 11 to rotate. The outer threaded sleeve 11 rotates and engages with the outer wall of the pressure sleeve 9, thereby causing the pressure sleeve 9 to slide along the guide bar 12 and abut against the outer side of the multiple pressure plates 8. At the same time, the pressure plates 8 are pressed down to rotate along the outer wall of the fixing sleeve 5 and simultaneously squeeze the return spring 16. Pressing, then the inner side of the pressure plate 8 contacts the abutment block 13 and applies downward pressure, causing the abutment block 13 to push the clamping plate 7 inward through the push rod 6 and simultaneously stretch the contraction spring 15. The clamping plate 7 at the bottom begins to clamp the outer layer of the thick rod 4 of the hinged structure 1. At this time, the soft pad 17 on the inner side of the clamping plate 7 is tightly attached to the surface of the thick rod 4 for clamping. When it is necessary to separate, the rotating sleeve 10 rotates in the opposite direction and engages with the pressure sleeve 9 through the outer thread sleeve 11, thereby causing the pressure sleeve 9 to slide upward to release the contact with the multiple sets of pressure plates 8. The multiple sets of pressure plates 8 rotate outward through the push of the return spring 16 to release the contact with the abutment block 13. Then the clamping plate 7 is pulled outward through the elastic contraction of the contraction spring 15 to release the fixation of the hinge mechanism.

[0037] Please see Figures 3-4 As one embodiment of the locking mechanism: the locking mechanism includes a locking groove 18, a locking block 19, a tension spring 20, a locking sleeve 21, a push spring 22, and a limiting rod 23. The locking groove 18 is provided in multiple sets distributed on the outer wall of the fixed sleeve 5. The locking block 19 is provided in multiple sets and slides on the rotating sleeve 10. The tension spring 20 is installed on the top of the multiple sets of locking blocks 19 and connected to the outer wall of the rotating sleeve 10. The locking sleeve 21 slides on the outer wall of the fixed sleeve 5. The push spring 22 is provided in multiple sets and its two ends are respectively connected to the top surface of the fixed sleeve 5 and the top surface of the locking sleeve 21. The limiting rod 23 is provided in multiple sets and is installed on the fixed sleeve 5 and slidably connected to the locking sleeve 21.

[0038] More specifically, when it is necessary to lock the rotating sleeve 10, the push spring 22 pushes the locking sleeve 21 to slide along the multiple sets of limiting rods 23, so that its inner wall abuts against the top of the multiple sets of locking blocks 19, so that the bottom of the multiple blocks is fastened in the locking groove 18, thus limiting the rotating sleeve 10. When it is necessary to unlock, the locking sleeve 21 is pushed upward to slide along the limiting rod 23, releasing the abutment against the multiple sets of locking blocks 19. Then, the locking blocks 19 are pulled outward by the tension spring 20 so that their bottom ends are disengaged from the locking groove 18, thereby releasing the rotating sleeve 10 so that it can continue to rotate.

[0039] In summary, during use or operation of the overall equipment: the stranded structure 1 consists of a central rod 2, thin rods 3, and thick rods 4. These rods are intertwined concentrically. The thin rods 3 are divided into multiple groups and are concentrically stranded around the outer layer of the central rod 2. The thick rods 4 are stranded around the outer layer of the thin rods 3, forming a multi-layer stranded structure. The fixing sleeve 5 is placed on the outer layer of the thick rods 4 of the stranded structure 1 to ensure that the fixing mechanism and the conductor core are aligned. Rotating the rotating sleeve 10 drives the outer threaded sleeve 11 to rotate. The outer threaded sleeve 11 rotates and engages with the outer wall of the pressure sleeve 9, thereby causing the pressure sleeve 9 to slide along the guide bar 12 and abut against the outer side of the multiple pressure plates 8. At the same time, the pressure plates 8 are pressed down to rotate along the outer wall of the fixing sleeve 5 and simultaneously engage the return spring. 16 is squeezed, and then the inner side of the pressure plate 8 contacts the abutment block 13 and applies downward pressure, so that the abutment block 13 pushes the clamping plate 7 inward through the push rod 6 and at the same time stretches the contraction spring 15. The clamping plate 7 at the bottom begins to clamp the outer layer of the thick rod 4 of the hinged structure 1. At this time, the soft pad 17 on the inner side of the clamping plate 7 is tightly attached to the surface of the thick rod 4 for clamping. When it is necessary to separate, the reverse rotating sleeve 10 is engaged with the pressure sleeve 9 through the outer thread sleeve 11, thereby driving the pressure sleeve 9 to slide upward to release the contact with the multiple sets of pressure plates 8. The multiple sets of pressure plates 8 are pushed outward by the return spring 16 to release the contact with the abutment block 13. Then the clamping plate 7 is pulled outward by the elastic contraction of the contraction spring 15 to release the fixation of the hinge mechanism.

[0040] When the rotating sleeve 10 needs to be locked, the push spring 22 pushes the locking sleeve 21 to slide along the multiple sets of limiting rods 23, so that its inner wall abuts against the top of the multiple sets of locking blocks 19, so that the bottom of the multiple blocks is fastened in the locking groove 18, thus limiting the rotating sleeve 10. When it is necessary to unlock, the locking sleeve 21 is pushed upward to slide along the limiting rod 23, releasing the abutment against the multiple sets of locking blocks 19. Then, the locking blocks 19 are pulled outward by the tension spring 20 so that their bottom ends are disengaged from the locking groove 18, thereby releasing the rotating sleeve 10 so that it can continue to rotate.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
