Abstract
Description
Technical Field
[0001] This utility model relates to the field of power cable technology, specifically a filling and twisting device for filling ropes in cables. Background Technology
[0002] In power cables, fillers are often used to fill the gaps created by stranding the cable cores, improving the cable's sealing performance. The most common filler rope is lightweight, flexible, and adaptable. Because filler rope stranding does not require excessive tension or a fixed pitch, the cage stranding and tubular stranding equipment commonly used in power cable stranding are not suitable for this purpose. Furthermore, using cage stranding and tubular stranding equipment for filler rope stranding would occupy equipment and reduce the utilization rate of power cable stranding. Chinese patent document CN217426452U discloses a filling rope twisting device, including a base 1 and a support plate 2. The support plate 2 is fixed on both the left and right sides above the base 1, and the support plate 2 on the right side is slidably connected to the base 1. A first sleeve rod 3 is set at the position directly above the base 1. A second sleeve rod 4 is set on the right side of the first sleeve rod 3, and the end of the second sleeve rod 4 away from the first sleeve rod 3 is connected to a docking plate 5. A first rotating rod 6 is set on the right end of the docking plate 5. The first sleeve rod 3 and the second sleeve rod 4 are connected by welding. The second sleeve rod 4 is trumpet-shaped. The first sleeve rod 3 and the second rotating rod 6 are welded together. The docking plate 5 and the second sleeve rod 4 are welded together. A locking block 14 is set on the outer wall of the left end of the first rotating rod 6. The locking block 14 is connected to the docking plate 5 through a docking groove 15. The docking groove 15 is opened on the inner wall of the docking plate 5. This structure is relatively complex. The first sleeve rod 3 and the second sleeve rod 4 are relatively long. The filling rope is relatively soft, making it inconvenient to thread the rope. Utility Model Content
[0003] The purpose of this invention is to provide a filling and twisting device that is simple in structure and easy to operate.
[0004] The basic technical solution for achieving the purpose of this utility model is: a filling and stranding device, characterized by the following structural features: a pay-off assembly, a splitting assembly, a paralleling assembly, and a take-up device. The pay-off assembly, splitting assembly, paralleling assembly, and take-up device are arranged sequentially from left to right. The pay-off assembly includes a pay-off turntable, a spool mounting post, and a turntable drive device. The spool mounting post is detachably and fixedly mounted on the right side of the pay-off turntable at equal circumferential angles. The turntable drive device drives the pay-off turntable to rotate. The splitting assembly includes a first splitting disc and a second splitting disc. The first and second splitting discs are coaxially and fixedly mounted on the right side of the pay-off turntable. The first splitting disc has a number of first splitting holes at equal circumferential angles, the same number as the number of spool mounting posts. The second splitting disc has a number of second splitting holes at equal circumferential angles, the same number as the number of spool mounting posts. The diameter of the circumference of each second splitting hole is smaller than the diameter of the circumference of each first splitting hole, and the diameter of the circumference of each first splitting hole is smaller than the diameter of the circumference of each spool mounting post. The parallel assembly includes a parallel die, which has parallel holes extending through its left and right sides.
[0005] Furthermore, for smooth twisting: the second wire distributor is shaped like a conical shell, with the left side smaller than the right. The axis of the second wire distributor hole is set along the line connecting the center of the right end face of the first wire distributor hole through which the corresponding filler rope passes to the center of the left end face of the paralleling hole of the paralleling die of the paralleling assembly.
[0006] Furthermore, to protect the filler rope and reduce wear, the left end of the parallel hole is chamfered.
[0007] Furthermore, to accommodate filler ropes with different stranding diameters, the paralleling assembly also includes a paralleling die mounting base, in which the paralleling die can be detachably installed.
[0008] Furthermore, to facilitate the take-up of the cable reel, a guide assembly is also included, located between the cable-combining assembly and the take-up device. The guide assembly includes horizontal limiting rollers and anti-wear rollers. There are two horizontal limiting rollers, sequentially mounted on corresponding mounting posts along the front-to-back direction. The horizontal limiting rollers are rotatably mounted on these mounting posts, with their rotation axes vertically aligned in the up-down direction. The anti-wear rollers are rotatably mounted on the aforementioned mounting posts, located to the right of the two horizontal limiting rollers, with their rotation axes horizontally aligned in the front-to-back direction.
[0009] Furthermore, to accommodate take-up reels of different sizes, the take-up device includes a take-up reel, a lifting device, and a drive device. The take-up reel is rotatably mounted on the lifting device, and is driven to rotate by the drive device.
[0010] The present invention has the following beneficial effects: (1) The filling and twisting device of the present invention has a simple structure and is easy to thread. It can be used for twisting filling ropes with different numbers of strands. The twisting die can be replaced. The twisting die with the corresponding twisting hole diameter of the filled rope after twisting is selected to ensure the twisting quality and prevent loosening. (2) The axis of the second twisting hole of the second dividing plate of the filling and twisting device of the present invention is set along the line connecting the center of the right end face of the first dividing hole through which the corresponding filling rope passes on the first dividing plate to the center of the left end face of the twisting hole of the twisting die of the twisting assembly. This has a better guiding and limiting effect, ensuring the angle of each filling rope during twisting and making the twisting more uniform. Attached Figure Description

[0022] See Figures 1 to 3 The filling and twisting device of this utility model includes a wire feeding assembly 1, a wire splitting assembly 2, a wire merging assembly 3, a guide assembly 4, and a wire take-up device 5. The wire feeding assembly 1, wire splitting assembly 2, wire merging assembly 3, guide assembly 4, and wire take-up device 5 are arranged sequentially from left to right.
[0023] The pay-off assembly 1 includes a pay-off turntable 1-1, spool mounting posts 1-2, and a turntable drive device 1-3. There are several spool mounting posts 1-2, each detachably and fixedly mounted at equal intervals along the circumference on the right side of the pay-off turntable 1-1. The specific number of posts is the same as the number of filler ropes to be twisted; in this embodiment, there are 12 posts. In use, 12 spools of filler rope are respectively mounted on one of the corresponding spool mounting posts 1-2. The pay-off turntable 1-1 is rotatable horizontally from its axis, and the turntable drive device 1-3 drives the pay-off turntable 1-1 to rotate. There are two sets of turntable drive devices 1-3, both with identical structures, each including a drive motor and drive rollers 1-31, with the drive motor driving the drive rollers 1-31 to rotate. Two sets of turntable drive devices 1-3 are respectively set on the front and rear sides of the wire feeding turntable 1-1. The wire feeding turntable 1-1 is in rolling contact with the drive roller 1-31, thereby driving the wire feeding turntable 1-1 to rotate by the drive roller 1-31.
[0024] See Figures 1 to 3 The wire distribution assembly 2 includes a first wire distribution reel 2-1 and a second wire distribution reel 2-2. The first wire distribution reel 2-1 is coaxially fixed on the right side of the wire feeding turntable 1-1, and the first wire distribution reel 2-1 rotates synchronously when the wire feeding turntable 1-1 rotates. The first wire distribution reel 2-1 has a number of first wire distribution holes 2-11 at equal intervals along the circumference, the same number as the number of wire reel mounting posts 1-2, and the first wire distribution holes 2-11 penetrate through the left and right sides of the first wire distribution reel 2-1.
[0025] See Figures 1 to 3The second wire distributor 2-2 is coaxially fixed on the right side of the first wire distributor 2-1. The second wire distributor 2-2 is generally conical in shape, with a smaller left side and a larger right side. The second wire distributor 2-2 has a number of second wire distributor holes 2-21 at equal intervals along its circumference, the same number as the number of wire distributor mounting posts 1-2. The axis of the second wire distributor holes 2-21 is connected to the center of the right end face of the first wire distributor hole 2-11 through which a corresponding filling rope passes on the first wire distributor 2-1, and then to the center of the left end face of the paralleling hole 3-21 of the paralleling assembly 3. The diameter of the circumference of each second wire distributor hole 2-21 is smaller than the diameter of the circumference of each first wire distributor hole 2-11, and the diameter of the circumference of each first wire distributor hole 2-11 is smaller than the diameter of the circumference of each wire distributor mounting post 1-2.
[0026] See Figures 1 to 3 The parallel assembly 3 includes a parallel mold mounting base 3-1 and a parallel mold 3-2. The parallel mold 3-2 can be detachably installed in the parallel mold mounting base 3-1. The parallel mold 3-2 is provided with parallel holes 3-21 that pass through it on both sides. The left end of the parallel hole 3-21 is chamfered to avoid wear on the filler rope.
[0027] See Figures 1 to 3 The guide assembly 4 includes a horizontal limiting roller 4-1 and an anti-wear roller 4-2. There are two horizontal limiting rollers 4-1, which are sequentially mounted on corresponding mounting posts along the front-to-back direction. Each horizontal limiting roller 4-1 is rotatably mounted on the mounting post, with its axis of rotation vertically along the up-down direction. The anti-wear roller 4-2 is rotatably mounted on the aforementioned mounting post, located to the right of the two horizontal limiting rollers 4-1, with its axis of rotation horizontally along the front-to-back direction.
[0028] See Figures 1 to 3 The take-up device 5 can employ existing technology and includes a take-up reel 5-1, a lifting device 5-2, and a drive device (not shown in the figure). There are two lifting devices 5-2, arranged sequentially in a front-to-back direction. The take-up reel 5-1 is rotatably mounted on the lifting devices 5-2 and is driven to rotate by the drive device. The lifting devices 5-2 are used to change the height of the rotation axis of the take-up reel 5-1, driving it to rise or fall, thus accommodating take-up reels 5-1 of different diameters.
[0029] When using the filling and twisting device of this utility model, several rolls (spools) of filling rope are respectively installed on the corresponding spool mounting posts 1-2. Then, each filling rope passes through the corresponding first dividing hole 2-11, second dividing hole 2-21 and parallel hole 3-21 in sequence. Then, it passes through the middle of the two horizontal limiting rollers 4-1 and passes over the anti-wear roller 4-2. Finally, each end is fixedly connected to the take-up spool 5-1. Then, the take-up spool 5-1 starts to rotate to take in the rope. At the same time, the pay-off turntable 1-1, the first dividing spool 2-1 and the second dividing spool 2-2 rotate together. After each filling rope comes out of the parallel hole 3-21, it is twisted together and then wound on the take-up spool 5-1.
