Description

Technical Field

[0001] This utility model relates to the field of cable stranding technology, and in particular to a high-speed stranding device for medium-voltage mineral cables. Background Technology

[0002] With the continuous advancement of power infrastructure construction, medium-voltage mineral cables, as a key carrier for power transmission, are experiencing a sustained increase in market demand. In application scenarios such as high-rise buildings, underground utility tunnels, and industrial plants, medium-voltage mineral cables must possess excellent electrical insulation performance, mechanical strength, and fire resistance to ensure the safe and stable operation of the power system.

[0003] Traditional stranding equipment mostly adopts a fixed structure design. When the stranding roller is full, the machine needs to be stopped and replaced. Moreover, the length of the stranding roller is fixed and cannot be flexibly adjusted according to needs. In addition, if the metal debris, lubricant and other impurities remaining on the cable surface are not cleaned in time, they will significantly reduce the adhesion of the insulation layer and cause safety hazards such as partial discharge. Existing devices generally lack online cleaning functions and rely on manual secondary processing, which further restricts the improvement of production efficiency and product quality.

[0004] Therefore, we propose a high-speed stranding device for medium-voltage mineral cables. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-speed stranded wire device for medium-voltage mineral cables.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A high-speed stranding device for medium-voltage mineral cables includes a base plate and an auxiliary mechanism. A rotating shaft is fixedly mounted on one end of the upper surface of the base plate, and a fixed plate is fixedly connected to the upper surface of the rotating shaft. The auxiliary mechanism is located on the upper surface of the fixed plate. The auxiliary mechanism includes stranding rollers, threaded grooves, and adjusting blocks. Stranding rollers are mounted on the upper surface of the fixed plate, and several stranding rollers are arranged in an array. A threaded groove is opened at the top of the stranding roller, and an adjusting block is movably mounted above the threaded groove. The adjusting block is threadedly connected to the threaded groove.

[0007] As a further embodiment of this utility model: a toothed ring is fixedly welded to the bottom end of the fixing plate, a transmission gear is meshed on one side of the toothed ring, and a drive motor is connected to the bottom end of the transmission gear.

[0008] As a further embodiment of this utility model: an auxiliary block is fixedly provided on the upper surface of the base plate at the end away from the auxiliary mechanism, and an arc-shaped groove is horizontally opened on the upper surface of the auxiliary block, and a cable body is placed inside the arc-shaped groove.

[0009] As a further embodiment of this utility model: threaded holes are symmetrically opened at both ends of the upper surface of the auxiliary block, and an auxiliary rod is fixedly installed inside the threaded hole, and the auxiliary rod is connected to the threaded hole by a thread.

[0010] As a further improvement of this utility model: a baffle is fixedly connected to one end of the auxiliary block near the auxiliary mechanism, a through hole is provided on one side of the baffle, and a sliding groove is provided on the upper surface of the baffle.

[0011] As a further improvement of this utility model: a cleaning block is movably arranged inside the chute, the cleaning block is made of sponge material, a protrusion is fixedly connected to the top of the cleaning block, and anti-slip texture is formed on the top of the protrusion.

[0012] Compared with the prior art, this utility model provides a high-speed stranding device for medium-voltage mineral cables, which has the following advantages: This invention, through the threaded groove on the top of the stranding roller in the auxiliary mechanism and the threaded connection of the adjusting block, allows for convenient adjustment of the height of the stranding roller. Operators can flexibly adjust the stranding specifications according to the stranding requirements of medium-voltage mineral cables of different specifications. At the same time, in conjunction with the bottom drive motor driving the transmission gear to mesh with the gear ring, the rotating shaft drives the fixed plate to rotate, thereby achieving the purpose of quick replacement of the stranding, thus improving the stranding efficiency and the practicality of the device.

[0013] This invention effectively supports and limits the cable body through the arc-shaped groove and auxiliary rod on the auxiliary block, ensuring stability during the stranding process. At the same time, the sliding groove on the baffle is combined with the cleaning block, which is made of sponge material. During the cable stranding process, the cable passes through the sponge cleaning block, allowing the cleaning block to adhere closely to the cable and clean debris, oil, and other impurities attached to the cable surface. This prevents foreign objects from affecting the cable's insulation performance and appearance quality, reduces subsequent cleaning processes, and thus improves product quality and production efficiency.

[0014] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0019] Example: A high-speed stranded wire device for medium-voltage mineral cables, such as... Figures 1-4 As shown, the system includes a base plate 1 and an auxiliary mechanism 2. A rotating shaft 3 is fixedly installed at one end of the upper surface of the base plate 1. A fixed plate 4 is fixedly connected to the upper surface of the rotating shaft 3. The auxiliary mechanism 2 is located on the upper surface of the fixed plate 4. The auxiliary mechanism 2 includes a stranding roller 201, a threaded groove 202, and an adjusting block 203. The stranding roller 201 is installed on the upper surface of the fixed plate 4, and several stranding rollers 201 are arranged in an array. A threaded groove 202 is opened at the top of the stranding roller 201. An adjusting block 203 is movably installed above the threaded groove 202. The adjusting block 203 is threadedly connected to the threaded groove 202. Through the threaded connection design between the threaded groove 202 at the top of the stranding roller 201 and the adjusting block 203 in the auxiliary mechanism 2, the height of the stranding roller 201 can be easily adjusted. The operator can flexibly adjust the stranding specifications according to the stranding requirements of medium-voltage mineral cables of different specifications.

[0020] like Figures 1-4As shown, a toothed ring 5 is fixedly welded to the bottom end of the fixed plate 4. A transmission gear 6 is meshed on one side of the toothed ring 5. A drive motor 7 is connected to the bottom end of the transmission gear 6. The drive motor 7 drives the transmission gear 6 to mesh with the toothed ring 5, and the fixed plate 4 is rotated through the rotating shaft 3, thereby achieving the purpose of quick replacement of winding, thus improving winding efficiency and the practicality of the device.

[0021] like Figures 1-4 As shown, an auxiliary block 8 is fixedly installed on the upper surface of the base plate 1 at the end away from the auxiliary mechanism 2. An arc-shaped groove 9 is horizontally opened on the upper surface of the auxiliary block 8. The cable body 10 is placed inside the arc-shaped groove 9. The cable body 10 is in the arc-shaped groove 9, so the arc-shaped groove 9 can simply limit its movement and prevent the cable from getting tangled during winding.

[0022] like Figures 1-4 As shown, threaded holes 11 are symmetrically opened at both ends of the upper surface of the auxiliary block 8. An auxiliary rod 12 is fixedly installed inside the threaded hole 11. The auxiliary rod 12 is connected to the threaded hole 11 by thread. The auxiliary rod 12, which is fixed by rotating the threads on both sides, further limits the cable body 10 and prevents it from sliding out of the limiting groove.

[0023] like Figures 1-4 As shown, a baffle 13 is fixedly connected to one end of the auxiliary block 8 near the auxiliary mechanism 2. A through hole 14 is provided on one side of the baffle 13, and a groove 15 is provided on the upper surface of the baffle 13. The cable body 10 can pass through the through hole 14 on one side of the baffle 13.

[0024] like Figures 1-4 As shown, a cleaning block 16 is movably installed inside the chute 15. The cleaning block 16 is made of sponge material. A protrusion 17 is fixedly connected to the top of the cleaning block 16. An anti-slip texture 18 is provided above the protrusion 17. Through the protrusion 17 and the anti-slip texture 18 at the top of the cleaning block 16, it is convenient to quickly replace the cleaning block 16 at any time to ensure the cleaning effect.

[0025] Working principle: During use, the threaded groove 202 on the top of the stranding roller 201 in the auxiliary mechanism 2 and the threaded connection design with the adjusting block 203 allow for convenient adjustment of the height of the stranding roller 201. Operators can flexibly adjust the stranding specifications according to the stranding requirements of different specifications of medium-voltage mineral cables. At the same time, the bottom drive motor 7 drives the transmission gear 6 to mesh with the toothed ring 5, and the rotating shaft 3 drives the fixed plate 4 to rotate, thereby achieving the purpose of quick change of stranding, thus improving stranding efficiency and device practicality. The arc groove 9 and auxiliary rod 12 on the auxiliary block 8 can effectively support and limit the cable body 10, ensuring that the stranding remains stable during the stranding process. Meanwhile, the sliding groove 15 on the baffle 13 is combined with the cleaning block 16. The cleaning block 16 is made of sponge material. During the cable stranding process, the cable passes through the sponge material cleaning block 16, so that the cleaning block 16 is in close contact with the cable to clean the debris, oil and other impurities attached to the cable surface, preventing foreign objects from affecting the cable insulation performance and appearance quality, reducing subsequent cleaning processes, and thus improving product quality and production efficiency.
