Description
Technical Field
[0001] This utility model application relates to the field of conductor straightening technology for the chemical cross-linking process of medium-voltage cables, specifically to a conductor straightening device for the chemical cross-linking process of medium-voltage cables. Background Technology
[0002] In the manufacturing process of wires and cables, conductors undergo a stranding process before being placed into reels. Stranding involves twisting multiple single wires together according to certain rules and structures to improve the conductor's flexibility and mechanical strength. However, during the process of the stranded conductor entering the reel, it is inevitably subjected to bending stress. These stresses cause internal stresses within the conductor and result in slight deformation of the conductor's geometry.
[0003] In the chemical cross-linking production process, the conductor is released from the reel and undergoes a series of bending and lowering processes. This process further exacerbates the accumulation of internal stress in the conductor and may lead to instability in the conductor structure. Due to internal stress and bending release, the conductor exhibits obvious "serpentine" fluctuations during unwinding. These fluctuations directly affect the quality of subsequent insulation extrusion, making it difficult to maintain a uniform thickness of the medium-voltage cable insulation layer during extrusion, resulting in excessive eccentricity and thus affecting the electrical performance of the product.
[0004] Currently, most chemical cross-linking production lines are not equipped with dedicated conductor stranding or straightening devices. This results in the inability to reduce or alleviate conductor bending and / or internal stress during actual production, thus affecting the production quality of medium-voltage cable insulation cores. Therefore, existing chemical cross-linking production lines have significant shortcomings in handling conductor bending and / or internal stress, necessitating the introduction of new technologies and equipment to solve this technical problem and ensure the production quality of medium-voltage cable insulation cores. Therefore, it is essential to invent a conductor straightening device for the chemical cross-linking process of medium-voltage cables to solve the aforementioned problems. Utility Model Content

[0029] To enable those skilled in the art to better understand the technical solution of this utility model application, the following will provide a more detailed description of this utility model application in conjunction with the accompanying drawings.
[0030] like Figures 1 to 5 As shown, a conductor straightening device for the chemical cross-linking process of medium-voltage cables includes:
[0031] Anti-slip straightening seat 1, installed on the ground;
[0032] The height-adjustable telescopic rod 2 is located above the anti-slip straightening seat 1;
[0033] The height-adjustable telescopic rod 2 is fixedly installed with a base support 5, and an installation plate 7 is connected above the base support 5;
[0034] A zero-degree straightening mechanism 12, a forty-five-degree straightening mechanism 8, a ninety-degree straightening mechanism 13, and a one-thirty-five-degree straightening mechanism 14 are mounted above the mounting plate 7. One side of the zero-degree straightening mechanism 12 is connected to the forty-five-degree straightening mechanism 8 via a threaded post 11. The forty-five-degree straightening mechanism 8 is threadedly connected to the ninety-degree straightening mechanism 13, and the ninety-degree straightening mechanism 13 is threadedly connected to the one-thirty-five-degree straightening mechanism 14. Each of the zero-degree straightening mechanism 12, forty-five-degree straightening mechanism 8, ninety-degree straightening mechanism 13, and one-thirty-five-degree straightening mechanism 14 includes:
[0035] A straightening mechanism plate 12 is equipped with a first straightening wheel 181, a first adjusting block 161, a first mounting block 162, a first bolt 163, a second straightening wheel 182, a second adjusting block 171, a second mounting block 172, and a second mounting bolt 173. The first mounting block 162 is externally rotatably connected to the first straightening wheel 181. The first adjusting block 161 is connected to the first mounting block 162 and is slidably connected to the straightening mechanism plate 12. The first adjusting block 161 is equipped with the first bolt 163, which is fastened to the first adjusting block 161. The second mounting block 172 is externally rotatably connected to the second straightening wheel 182. The second adjusting block 171 is connected to the second mounting block 172 and is slidably connected to the straightening mechanism plate 12. The second adjusting block 171 is equipped with the second bolt 173, which is fastened to the second adjusting block 171.
[0036] In some embodiments, such as Figure 1As shown, zero degrees means that the placement direction of the zero-degree straightening mechanism 12 (vertical placement) is parallel to the vertical plane; forty-five degrees means that the placement direction of the forty-five-degree straightening mechanism 8 (tilted placement) forms a forty-five-degree angle with the vertical plane; zero degrees means that the placement direction of the ninety-degree straightening mechanism (horizontal placement) is perpendicular to the vertical plane; and one hundred and thirty-five degrees means that the placement direction of the one hundred and thirty-five-degree straightening mechanism (tilted placement) forms a one hundred and thirty-five-degree angle with the vertical plane.
[0037] In some embodiments, such as Figure 4 As shown, the first adjusting block 161 can be slidably connected to the straightening mechanism plate 12 via the slide groove 15, and the second adjusting block 171 can be slidably connected to the straightening mechanism plate 12 via the slide groove 15. This allows the first adjusting block 161 to drive the first straightening wheel 181 to slide up and down, and the second adjusting block 171 to drive the first straightening wheel 182 to slide up and down. This makes it suitable for conductors used in the chemical cross-linking process of medium-voltage cables of different diameters.
[0038] In some embodiments, such as Figure 1 As shown, firstly, multiple support rods can be installed on the mounting plate, such as two support rods, three support rods, four support rods, etc. These multiple support rods can jointly support the 45-degree straightening mechanism and the 90-degree straightening mechanism, allowing the mounting plate to accommodate the 0-degree straightening mechanism, the 45-degree straightening mechanism, the 90-degree straightening mechanism, and the 135-degree straightening mechanism. Simultaneously, when using the aforementioned conductor straightening device for the medium-voltage cable chemical cross-linking process, multiple threaded posts 11 can be used to assemble the 0-degree straightening mechanism, the 45-degree straightening mechanism, the 90-degree straightening mechanism, and the 135-degree straightening mechanism. Furthermore, the conductor for the medium-voltage cable chemical cross-linking process is pulled by traction wheels on both sides. During the pulling process, the conductor passes sequentially through the 0-degree straightening mechanism, the 45-degree straightening mechanism, the 90-degree straightening mechanism, and the 135-degree straightening mechanism, and the conductor remains in a straight line.
[0039] In some embodiments, the first adjusting block 161 and the first mounting block 162 are detachably connected. The first adjusting block 161 is provided with a countersunk hole, through which the first bolt 163 passes. The end of the first bolt 163 can be installed in the countersunk hole, and a nut can be installed on the threaded part of the first bolt 163. After the first adjusting block 161 drives the first straightening wheel 181 to slide up and down to determine the position, the nut can secure the first bolt 163 to the first adjusting block 161.
[0040] In some embodiments, the second adjusting block 171 and the second mounting block 172 are detachably connected. The second adjusting block 171 is also provided with a countersunk hole, through which the second bolt 173 passes. The end of the second bolt 173 can also be installed in the countersunk hole, and a nut can be installed on the threaded part of the second bolt 173. After the second adjusting block 171 drives the second straightening wheel 182 to slide up and down to determine the position, the nut can secure the second bolt 173 to the second adjusting block 171.
[0041] In some embodiments, after the first adjusting block 161 drives the first straightening wheel 181 to slide up and down to determine its position, the nut can secure the first bolt 163 to the first adjusting block 161. After the second adjusting block 171 drives the second straightening wheel 182 to slide up and down to determine its position, the nut can secure the second bolt 173 to the second adjusting block 171. The vertical distance between the first straightening wheel 181 and the second straightening wheel 182 can then be determined. The vertical distance between the first straightening wheel 181 and the second straightening wheel 182 is usually adapted to the size of the conductor used in the chemical cross-linking process of medium-voltage cables. Of course, in actual use of the conductor straightening device for the chemical cross-linking process of medium-voltage cables, the vertical distance between the first straightening wheel 181 and the second straightening wheel 182 is usually adjusted according to the actual size of the conductor used in the chemical cross-linking process of medium-voltage cables, through the first adjusting block 161, the first bolt 163 and the nut, the second adjusting block 171, the second bolt 173 and the nut. Then, the first straightening wheel 181 and the second straightening wheel 182 in the zero-degree straightening mechanism 12, the forty-five-degree straightening mechanism 8, the ninety-degree straightening mechanism 13 and the one hundred and thirty-five-degree straightening mechanism 14 can straighten the conductor used in the chemical cross-linking process of medium-voltage cables.
[0042] In some embodiments, the zero-degree straightening mechanism, the forty-five-degree straightening mechanism, the ninety-degree straightening mechanism, and the one hundred and thirty-five-degree straightening mechanism may be used selectively, or all of the zero-degree straightening mechanism, the forty-five-degree straightening mechanism, the ninety-degree straightening mechanism, and the one hundred and thirty-five-degree straightening mechanism may be used; or all of the zero-degree straightening mechanism and the ninety-degree straightening mechanism may be used; or all of the forty-five-degree straightening mechanism and the one hundred and thirty-five-degree straightening mechanism may be used. Those skilled in the art may choose according to the actual situation.
[0043] In some embodiments, such as Figure 4As shown, multiple sets of slide grooves 15 can be provided, for example, two sets; multiple sets of the first straightening wheel 181, the first adjusting block 161, the first mounting block 162, and the first bolt 163 can be provided, for example, two sets; multiple sets of the second straightening wheel 182, the second adjusting block 171, the second mounting block 172, and the second mounting bolt 173 can be provided, for example, two sets. Each set of slide grooves 15, and each set of the first straightening wheel 181, the first adjusting block 161, the first mounting block 162, the first bolt 163, the second straightening wheel 182, the second adjusting block 171, the second mounting block 172, and the second mounting bolt 173 are all provided in a one-to-one correspondence.
[0044] In this utility model application, by providing an mounting plate, a zero-degree straightening mechanism, a 45-degree straightening mechanism, a 90-degree straightening mechanism, and a 135-degree straightening mechanism, when using the above-mentioned conductor straightening device for the chemical cross-linking process of medium-voltage cables, the zero-degree straightening mechanism, the 45-degree straightening mechanism, the 90-degree straightening mechanism, and the 135-degree straightening mechanism are assembled through multiple threaded posts. In this way, according to the selection of a suitable straightening method, the conductor for the chemical cross-linking process of medium-voltage cables, pulled by the traction wheel, passes through the zero-degree straightening mechanism, the 45-degree straightening mechanism, the 90-degree straightening mechanism, and the 135-degree straightening mechanism. This allows the conductor for the chemical cross-linking process of medium-voltage cables to be affected by the up-and-down rotating straightening wheel, thereby completing the straightening work of the conductor for the chemical cross-linking process of medium-voltage cables. This ensures that the conductor for the chemical cross-linking process of medium-voltage cables maintains good straightness in the subsequent extrusion process, reduces or alleviates the bending and / or internal stress of the conductor for the chemical cross-linking process of medium-voltage cables, improves the production quality of the insulation core of medium-voltage cables, and thus improves the quality and reliability of the finished cable.
[0045] Optional, such as Figure 5 As shown, the zero-degree straightening mechanism, the forty-five-degree straightening mechanism, the ninety-degree straightening mechanism, and the one hundred and thirty-five-degree straightening mechanism all include: a screw 21, which is threadedly connected to the straightening mechanism plate 12, a handwheel 22 is fixedly installed on the top of the screw 21, and a guide hoop 23 is threadedly connected to the bottom of the screw 21.
[0046] In some embodiments, the screw 21 is threadedly connected to the straightening mechanism plate 12, a handwheel 22 is fixedly installed on the top of the screw 21, and a guide clamp 23 is threadedly connected to the bottom of the screw 21. The screw 21, handwheel 22 and guide clamp 23 can be configured in multiple groups, such as four groups. Each group of screw 21, handwheel 22 and guide clamp 23 can further assist in guiding the conductor used in the chemical cross-linking process of medium-voltage cable to ensure the straightness of the conductor used in the chemical cross-linking process of medium-voltage cable during traction.
[0047] In this utility model application, the straightening work of the conductor used in the chemical cross-linking process of medium-voltage cable is further completed through the joint cooperation of the first straightening wheel 181, the second straightening wheel 182 and the guide hoop 23, which further ensures that the conductor used in the chemical cross-linking process of medium-voltage cable maintains good straightness in the subsequent extrusion process, and reduces or alleviates the bending and / or internal stress of the conductor used in the chemical cross-linking process of medium-voltage cable.
[0048] Optionally, two first mounting seats 6 and two angle-adjusting telescopic rods 9 are fixedly installed on the top of the base 5. Each angle-adjusting telescopic rod 9 is connected to a second mounting seat 10. One side of the mounting plate 7 is hinged to the two first mounting seats 6, and the other side of the mounting plate 7 is connected to the two second mounting seats 10.
[0049] In some embodiments, one side of the mounting plate 7 is hinged to two first mounting seats 6, and the mounting plate 7 can rotate relative to the base 5 to achieve angle adjustment. One end of the angle adjustment telescopic rod 9 is connected to the base 5, and the other end of the angle adjustment telescopic rod 9 is connected to a second mounting seat 10. The other side of the mounting plate 7 is connected to two second mounting seats 10. In this way, by means of the angle adjustment telescopic rod 9, the mounting plate 7 can be rotated relative to the base 5 to achieve angle adjustment, thereby changing the positions of the zero-degree straightening mechanism, the forty-five-degree straightening mechanism, the ninety-degree straightening mechanism, and the one-thirty-five-degree straightening mechanism.
[0050] In this utility model application, the overall height of the conductor straightening device for the chemical cross-linking process of medium-voltage cables is adjusted by adjusting the height adjustment telescopic rod, so that the conductor straightening device for the chemical cross-linking process of medium-voltage cables can meet the height of different cable traction wheels; at the same time, by controlling the up and down orientation angles of the zero-degree straightening mechanism, the forty-five-degree straightening mechanism, the ninety-degree straightening mechanism, and the one hundred and thirty-five-degree straightening mechanism, different conductor straightening requirements for the chemical cross-linking process of medium-voltage cables are met. This combination enhances the adaptability of the conductor straightening device for the chemical cross-linking process of medium-voltage cables to meet the usage requirements.
[0051] Optionally, the mounting plate is provided with fastening bolts, and the front end of the fastening bolts is threadedly connected to a base.
[0052] In this utility model application, the mounting plate 3 and the base 5 are detachably connected. In the actual installation process, the mounting plate and the base 5 can be quickly and conveniently combined and adjusted according to different installation environments and needs, effectively saving installation time and labor costs. At the same time, the detachable connection makes daily inspection and maintenance work easier. Maintenance personnel can easily disassemble the parts, conduct a comprehensive inspection of the internal structure, and promptly identify and resolve potential problems.
[0053] Optionally, the guide clamp is provided with a groove through which a conductor for the chemical cross-linking process of the medium-voltage cable passes.
[0054] In the application of the present utility model, a groove is provided on the guide collar for the conductor used in the chemical cross-linking process of the medium-voltage cable to pass through. The groove can provide guidance for the conductor used in the chemical cross-linking process of the medium-voltage cable during the traction process. Exemplarily, along the vertical plane direction, the height of the groove is H, and along the direction perpendicular to the vertical plane, the width of the groove is D. The diameter of the conductor used in the chemical cross-linking process of the medium-voltage cable is d, satisfying: 1.0d < D ≤ 1.2d, 1.0d ≤ H / D ≤ 2.0. Preferably, 1.0d ≤ H / D ≤ 1.2. As much as possible, prevent the conductor used in the chemical cross-linking process of the medium-voltage cable during traction from shaking and deviating. The groove can contact the conductor used in the chemical cross-linking process of the medium-voltage cable, and further can ensure the straightness of the conductor used in the chemical cross-linking process of the medium-voltage cable during traction.
[0055] The usage method of the straightening device for the conductor used in the chemical cross-linking process of the medium-voltage cable includes:
[0056] First, before the conductor used in the chemical cross-linking process of the medium-voltage cable is tractioned by the traction wheels on both sides, use the above-mentioned straightening device for the conductor used in the chemical cross-linking process of the medium-voltage cable. The first straightening wheels and the second straightening wheels of the zero-degree straightening mechanism, the first straightening wheels and the second straightening wheels of the forty-five-degree straightening mechanism, the first straightening wheels and the second straightening wheels of the ninety-degree straightening mechanism, and the first straightening wheels and the second straightening wheels of the one-hundred-and-thirty-five-degree straightening mechanism are all in the position with the maximum vertical distance. According to the current traction direction and traction height of the conductor used in the chemical cross-linking process of the medium-voltage cable, adjust the overall height of the straightening device for the conductor used in the chemical cross-linking process of the medium-voltage cable by adjusting the height-adjusting telescopic rod 2. By adjusting the height of the angle-adjusting telescopic rod 9, adjust the orientation angle of the mounting plate 7 on the bottom support base 5, so that the conductor used in the chemical cross-linking process of the medium-voltage cable passes through the zero-degree straightening mechanism, the forty-five-degree straightening mechanism, the ninety-degree straightening mechanism, and the one-hundred-and-thirty-five-degree straightening mechanism in sequence. The conductor used in the chemical cross-linking process of the medium-voltage cable is all corresponding to the first straightening wheels and the second straightening wheels of the zero-degree straightening mechanism, the first straightening wheels and the second straightening wheels of the forty-five-degree straightening mechanism, the first straightening wheels and the second straightening wheels of the ninety-degree straightening mechanism, and the first straightening wheels and the second straightening wheels of the one-hundred-and-thirty-five-degree straightening mechanism;
[0057] Then, the first and second adjusting blocks are adjusted so that the first and second straightening wheels of the zero-degree straightening mechanism contact the conductor used in the chemical cross-linking process of the medium-voltage cable, and are tightened by the first bolt and nut. The first bolt 163 is fastened to the first adjusting block 171 by the nut, and the second bolt 173 is fastened to the second adjusting block 171 by the nut. The first and second adjusting blocks are then adjusted so that the first and second straightening wheels of the forty-five-degree straightening mechanism contact the conductor used in the chemical cross-linking process of the medium-voltage cable, and are tightened by the first bolt and nut. The first bolt 163 is fastened to the first adjusting block 171 by the nut. The first and second adjusting blocks are fixedly connected, with the second bolt 163 and the first adjusting block 171 fastened together by a nut. The first and second adjusting blocks are adjusted so that the first and second straightening wheels of the 90-degree straightening mechanism contact the conductor used in the chemical cross-linking process of the medium-voltage cable, and are fastened together by the first bolt and nut. The first bolt 163 is also fastened to the first adjusting block 171 by a nut, and the second bolt 173 is fastened to the second adjusting block 171 by a nut. The first and second adjusting blocks are then adjusted so that the first and second straightening wheels of the 135-degree straightening mechanism contact the conductor used in the chemical cross-linking process of the medium-voltage cable, and are fastened together by the first bolt and nut. A bolt and nut are tightened, with the first bolt 163 and the first adjusting block 171 connected by a nut, and the second bolt 173 and the second adjusting block 171 connected by a nut. Adjustment ensures that the conductor used in the chemical cross-linking process of the medium-voltage cable moves, thereby effectively driving the rotation of the first and second straightening wheels of the zero-degree straightening mechanism, the forty-five-degree straightening mechanism, the ninety-degree straightening mechanism, and the one-thirty-five-degree straightening mechanism. The handwheel is rotated to rotate the threaded rod, thereby adjusting the guide of the zero-degree straightening mechanism. The conductor used in the chemical cross-linking process of medium-voltage cables is straightened by rotating a handwheel to rotate a threaded rod, thereby adjusting the guide of the straightening mechanism at a 45-degree angle. The handwheel is also rotated to rotate a threaded rod to adjust the guide of the straightening mechanism at a 90-degree angle. Finally, the handwheel is rotated to rotate a threaded rod to adjust the guide of the straightening mechanism at a 135-degree angle, ensuring the conductor is in a straight state. This completes the pre-use preparation work for the conductor straightening device in the chemical cross-linking process of medium-voltage cables.
[0058] In some embodiments, a zero-degree straightening mechanism and a 90-degree straightening mechanism may be selectively used. In this case, the first straightening wheel, the second straightening wheel, and the guide clamp of the 45-degree straightening mechanism are not adjusted to avoid contact with the conductor used in the chemical cross-linking process of the medium-voltage cable, and the first straightening wheel, the second straightening wheel, and the guide clamp of the 135-degree straightening mechanism are not adjusted to avoid contact with the conductor used in the chemical cross-linking process of the medium-voltage cable. Alternatively, a 45-degree straightening mechanism and a 135-degree straightening mechanism may be selectively used.

[0059] Finally, during the chemical cross-linking process of medium-voltage cables, the conductor is pulled by the traction wheels on both sides and influenced by the first and second straightening wheels of the zero-degree, forty-five-degree, ninety-degree, and one-thirty-five-degree straightening mechanisms, which rotate up and down respectively. This allows the straightening of the conductor in the chemical cross-linking process of medium-voltage cables to be performed and completed. Therefore, based on the above operations, the installation and use of the conductor straightening device for the chemical cross-linking process of medium-voltage cables can be basically completed. Routine maintenance of the device is sufficient, ensuring its long-term usability.
