Description

Technical Field

[0001] The present invention relates to the technical field of cross-linked polyethylene power cable processing, and specifically to a power cable core stranding and wire separating device and a wire separating method. Background Art

[0002] The wound power cable core is the core part of the cable, usually composed of multiple fine wires stranded together to enhance its mechanical strength and conductivity. During the winding process, the outside of the core is pre-wrapped with a cross-linked polyethylene layer, which has excellent insulation performance and heat resistance and can effectively protect the core from the influence of the external environment. The power cable core stranding and wire separating device is a mechanical device specifically used to strand multiple fine wires together according to specific rules. Through an accurate control system, the device ensures that each wire maintains uniform tension during the stranding process, thereby forming a core with a compact structure and stable performance.

[0003] Chinese Patent with Publication No. CN213905027U discloses a power cable core stranding and wire separating device. During the wire separating process of the power cable core stranding and wire separating device, when the stranding disc rotates and drives the core wrapped with cross-linked polyethylene to wind the core, it is impossible to adjust the position and quantity of the through holes and buffer blocks for placing the core. Summary of the Invention

[0004] The purpose of the present invention is to provide a power cable core stranding and wire separating device and a wire separating method. By adding mounting rings one by one, finally making the number of mounted mounting rings and the number of mounted fixing rings correspond to the power cable core to be wound, additional mounting rings can adapt to different mounting requirements and different winding requirements, solving the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A power cable core stranding and wire separating device, including a base with a winding frame on one side of the upper end. On the other side of the upper end of the base, a second fixing frame is provided. Inside the second fixing frame, a fixing ring is provided. On the other side of the fixing ring, a number of mounting rings are arranged in sequence. In the middle of the fixing ring and the mounting ring, a connecting block is welded and fixedly connected through a pair of connecting bars. On the other side of the connecting block, a second mounting groove is provided. On one side of the second mounting groove, a threaded groove is provided. On one side of the connecting block inside the mounting ring, a first extension block is provided. In the middle of the connecting block inside the mounting ring, a reserved groove with a bolt is provided. By installing the mounting rings one by one, different wire core winding requirements can be adapted, and the wire cores can be fixed one by one, facilitating subsequent winding.

[0006] Preferably, the number of the mounting rings and the fixing rings corresponds to the number of the winding cores. By corresponding the number of the mounting rings and the fixing rings to different cores one by one, all the cores can be fixed separately at the required positions and angles.

[0007] Preferably, the reserved groove penetrates through the first extension block and extends to one side of the threaded groove. The outer part of the bolt is in threaded fit with the threaded groove. After the bolt extends out, the rotation of the bolt can be in threaded fit with the threaded groove and fixed. After the threaded fit, fully tightening the bolt can fix the subsequent connected mounting ring.

[0008] Preferably, the second fixing frame is provided with a first mounting groove, and the fixing ring is embedded inside the first mounting groove and rotatably connected with the first mounting groove. The fixing ring is circumferentially welded with a toothed groove, and a gear engaged with the toothed groove is arranged at the lower end outside the toothed groove. By driving the gear, the fixing ring and the mounting ring connected to the side of the fixing ring can be rotated simultaneously to realize the winding of the core.

[0009] Preferably, third fixing frames are arranged at the front and rear ends on the other side of the second fixing frame. Both of the two third fixing frames are rotatably connected with support rollers on the other side of the second fixing frame. The support rollers can support the additionally mounted mounting ring at the upper end and can continuously support the rotating mounting ring to improve the stability during the operation of the equipment.

[0010] Preferably, mounting holes are longitudinally and uniformly distributed inside the connecting strip. Fixing frames connected to the mounting holes by bolts are arranged on the sides of a pair of the connecting strips. The reserved mounting holes can enable the fixing frames to be mounted at different horizontal positions to meet the requirements of different mounting heights.

[0011] Preferably, a first clamping rod and a second clamping rod are sequentially arranged at the upper and lower ends inside the fixing frame. Both ends of the second clamping rod are rotatably connected with the fixing frame. Second extension blocks are rotatably arranged at both ends of the first clamping rod. The second extension blocks are embedded inside the fixing frame and slidably connected with the inside of the fixing frame. The rotation of the first clamping rod and the second clamping rod can avoid the friction generated during the transmission of the core.

[0012] Preferably, a unidirectional threaded rod in threaded fit is arranged through the area where the second extension block slides inside the fixing frame. The first clamping rod can be driven by the unidirectional threaded rod to move towards the second clamping rod to adjust the distance between the second clamping rod and the first clamping rod, and the adjustment of the distance can adapt to cores with different diameters.

[0013] A wire splitting method for a wire stranding and wire splitting device of a power cable core includes the following steps:

[0014] Step 1: The mounting rings are sequentially attached and mounted on the sides of the fixing rings inside the second fixing frame.

[0015] Step 2: When the mounting ring is connected to the fixing ring, the first extension block protruding from the connecting block inside the mounting ring is inserted into the second mounting groove of the connecting block inside the fixing ring. When two mounting rings are connected, the first extension block protruding from the connecting block inside one mounting ring is inserted into the second mounting groove of the connecting block inside the other mounting ring.

[0016] Step 3: The screwdriver touches the bolt inside the reserved groove, so that the bolt touches the inside of the thread groove adjacent to the position where the first extension block is inserted, and the subsequently additionally installed mounting ring is fixed through the thread fit between the thread groove and the bolt.

[0017] Step 4: Before the bolt is fully tightened and the mounting ring is fixed, the mounting ring pre-adjusts the angle of the internal connecting strip in advance. After the angle is adjusted, the bolt is fully tightened.

[0018] Step 5: After the bolt penetrates through the four corner positions of the fixing frame, it is inserted into the mounting holes evenly distributed longitudinally inside the connecting strip.

[0019] Step 6: The wire core passes through between the first clamping rod and the second clamping rod inside the fixing frame, and at the same time, the one-way threaded rod is rotated so that the first clamping rod clamps the penetrated wire core towards the second clamping rod.

[0020] Step 7: The rotation of the gear can drive the fixing ring to rotate through the tooth groove, and the mounting rings connected in sequence on the side and the wire core fixed inside rotate and are wound.

[0021] Step 8: After the wound wire core is pressed and transmitted by adjusting the position of the fixing mechanism, the winding frame rotates and winds up the wound cable.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. According to the number of wire cores wrapped with cross-linked polyethylene, the present invention additionally adds the corresponding number of mounting rings. The bolts inside the correspondingly added mounting rings protrude one by one, so that the bolts inside the additionally installed mounting rings are in thread fit with the thread grooves at the required connection positions. After the bolts are rotated and tightened, the mounting rings can be closely attached and fixed. Before the bolts are rotated and tightened, the mounting rings can rotate and pre-adjust the angles of the corresponding connecting strips, so that when the subsequent wire cores pass through the connecting strips for subsequent stirring, they can adapt to the winding angles and winding position requirements of different wire cores. The mounting rings are convenient to install, and the number of installed mounting rings can be flexibly adjusted according to the number of wire cores.

[0024] 2. The surface of the connecting bar of the present invention can be penetrated and fixed by bolts through the fixing frame. The connecting bar is provided with mounting holes at different positions, which can make the fixing frame fit the connecting bar at different angles and then be fixed at the corresponding horizontal height to adapt to different winding requirements. At the same time, during the winding process, the distance between the first clamping rod and the second clamping rod can be adjusted by rotating the unidirectional threaded rod. The adjustment of the distance can further adapt to the wire core diameter and avoid friction. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The present invention will be further described below in conjunction with specific embodiments.

[0035] Example 1: As Figure 1 shown, a wire splitting device for a power cable core stranded wire in this embodiment includes a base 1. On one side of the upper end of the base 1, a winding frame 2 is provided. After the core wrapped with cross-linked polyethylene is wound by rotation, the power cable core is wound and collected by the rotation of the rotating winding frame 2;

[0036] Among them, in order to drive the wound power cable core so that the core wrapped with cross-linked polyethylene actively transmits towards the winding frame 2 after winding, a pair of adjusting and fixing mechanisms 3 are provided at the middle position of the upper end of the base 1. A length sensor for measuring the distance is provided at the lower end between the pair of adjusting and fixing mechanisms 3;

[0037] In addition, regarding the drive structure inside the length sensor and the adjusting and fixing mechanism 3, refer to the Chinese patent with the reference number CN213905027U. In this application, the inside of the adjusting and fixing mechanism 3 and the length sensor are both described, so there is no excessive elaboration in this application;

[0038] In order to fix multiple cores wrapped with cross-linked polyethylene and to assist subsequent winding, a second fixing frame 6 is provided on the other side of the upper end of the base 1. A fixing ring 15 is provided inside the second fixing frame 6. The fixing ring 15 itself can fix and limit one core wrapped with cross-linked polyethylene. As Figure 3 shown, a number of mounting rings 7 are arranged in sequence on the other side of the fixing ring 15. The number of mounting rings 7 and the fixing ring 15 corresponds to the number of winding cores. The mounting ring 7 itself can, like the fixing ring 15, fix and limit one core wrapped with cross-linked polyethylene. For the cores to be wound this time, excluding one core that can be fixed by the fixing ring 15, the remaining cores to be fixed are fixed by installing the corresponding number of mounting rings 7;

[0039] Among them, connection blocks 19 are provided in the middle of the fixing ring 15 and the mounting ring 7. A pair of connection bars 20 are arranged between the outer wall of the connection block 19 and the inner wall of the corresponding fixing ring 15 and mounting ring 7. And both ends of the connection bar 20 are welded and fixed to the connected fixing ring 15, mounting ring 7 and connection block 19. The adjacent mounting rings 7 can be connected one by one through the connection block 19, and gradually connected to the side of the fixing ring 15, and the connection quantity is increased one by one to adapt to different stranding requirements;

[0040] In addition, in order to adapt to the stranding positions of different cores, as Figure 4 and Figure 5As shown, mounting holes 31 are evenly distributed longitudinally inside the connecting bar 20. On the sides of a pair of connecting bars 20, there are fixed frames 32 bolted to the positions of the mounting holes 31. The bolts penetrate the mounting holes 31 at different horizontal positions, enabling the fixed frames 32 to be fixed at different horizontal heights, adapting to the winding positions of the subsequent winding wire cores and different winding requirements;

[0041] To prevent the wire core from wobbling and experiencing high-frequency friction when winding inside the fixed frame 32, as Figure 8 shown, a first clamping rod 33 is provided at the upper end inside the fixed frame 32, and a second clamping rod 34 is provided at the lower end inside the fixed frame 32. Both ends of the second clamping rod 34 are rotatably connected to the fixed frame 32. When the wound wire core is clamped by the first clamping rod 33 and the second clamping rod 34 and rotated to complete subsequent winding, part of the friction during wire core clamping is offset by the rotation of the second clamping rod 34;

[0042] Among them, to adjust the horizontal position of the first clamping rod 33 and avoid friction between the wire core and the position of the first clamping rod 33, second extension blocks 35 are rotatably provided at both ends of the first clamping rod 33. The second extension blocks 35 are embedded inside the fixed frame 32 and slidably connected to the inside of the fixed frame 32. A one-way threaded rod 36 is provided through the area where the second extension blocks 35 slide inside the fixed frame 32, and the outside of the one-way threaded rod 36 is in threaded cooperation with the penetration position of the second extension blocks 35. By rotating the one-way threaded rod 36, the first clamping rod 33 can be adjusted longitudinally in the horizontal position, and the first clamping rod 33 can rotate outside the second extension blocks 35 to further offset the friction force;

[0043] To fix the mounting ring 7, on the other side of the connecting block 19, a second mounting groove 21 is provided towards the middle position of the connecting block 19. A threaded groove 25 is provided in the second mounting groove 21 towards the middle position of the connecting block 19. The reserved threaded groove 25 facilitates the subsequent rotation and fixation of the bolt 23. On the side of the mounting ring 7 corresponding to the connecting block 19, a protruding first extension block 22 is provided, and it is an integral structure with the connecting block 19 inside the mounting ring 7. After the mounting ring 7 is connected to the fixed ring 15, the connecting block 19 inside the mounting ring 7 is inserted into the second mounting groove 21 reserved for the connecting block 19 inside the fixed ring 15 through the first extension block 22, realizing preliminary connection and combination;

[0044] Among them, a reserved groove 24 is provided at the middle position of the connecting block 19 inside the mounting ring 7. The reserved groove 24 penetrates the first extension block 22 and extends to one side of the threaded groove 25, as Figure 6As shown, there is a non-removable bolt 23 reserved inside the reserved slot 24. When not in use, the bolt 23 is stored inside the second clamping rod 34. When fixation is required, for example, when connecting the connecting block 19 inside the mounting ring 7 to the connecting block 19 inside the fixing ring 15, the first extension block 22 inside the mounting ring 7 is inserted into the second mounting slot 21 inside the fixing ring 15. A screwdriver contacts and rotates the bolt 23 inside the mounting ring 7 through the threaded slot 25 inside the mounting ring 7, causing the bolt 23 to rotate into the threaded slot 25 inside the fixing ring 15. Before the bolt 23 is fully tightened and the subsequent mounting ring 7 is fixed, the mounting ring 7 rotates and adjusts its angle so that the corresponding first clamping rod 33 and second clamping rod 34 of the mounting ring 7 are at the required fixing angle, and the outside of the bolt 23 is in threaded engagement with the threaded slot 25;

[0045] When the first clamping rod 33 fully extends and is fixed outside the threaded slot 25, space will be reserved inside the reserved slot 24 to facilitate the subsequent extension of the bolt 23. The number of mounting rings 7 to be installed is adjusted one by one according to the number of winding cores, avoiding the simultaneous erection of too many mounting rings 7 inside the device, adapting to different usage environments, and reducing the transmission pressure at the position of the gear 17;

[0046] To facilitate the driving of the fixing ring 15, a first mounting slot 18 is recessed inside the second fixing frame 6, and the fixing ring 15 is embedded inside the first mounting slot 18 and rotatably connected to the inside of the first mounting slot 18. When driving the fixing ring 15, the fixing ring 15 continuously rotates inside the first mounting slot 18;

[0047] Among them, a tooth groove 16 is circumferentially arranged at the middle position of the fixing ring 15. The tooth groove 16 is stored inside the first mounting slot 18. A gear 17 is arranged at the lower end outside the tooth groove 16, and the outside of the gear 17 is meshed with the outside of the tooth groove 16. After the gear 17 is driven by a motor, the gear 17 will drive the fixing ring 15 and the subsequent mounting ring 7 at the rear end to rotate synchronously through the tooth groove 16;

[0048] In addition, to support the subsequent mounting ring 7 installed, and to prevent the second fixing frame 6 from tilting and breaking, third fixing frames 9 are arranged at both the front and rear ends on the other side of the second fixing frame 6. Support rollers 8 are arranged between the two third fixing frames 9 and the other side of the second fixing frame 6, and both ends of the support rollers 8 are rotatably connected to the third fixing frames 9 and the second fixing frame 6 respectively. The support rollers 8 can support the additionally installed mounting ring 7 at the upper end. During the contact and support process, the gear 17 will drive the fixing ring 15 and the mounting ring 7 to rotate. When rotating, the support rollers 8 can synchronously support the mounting ring 7 in the rotating state while maintaining the support ability when contacting the mounting ring 7;

[0049] Embodiment 2: As Figure 2 and Figure 7As shown, in order to generate additional torsional force, the winding effect of the cable can be improved. A worm 5 is provided between one of the adjusting and fixing mechanisms 3 close to the second fixing frame 6 and the second fixing frame 6. A worm gear 10 is provided at the lower end of the outside of the worm 5, and the outside of the worm gear 10 is meshed and connected with the outside of the worm 5. After being driven by electricity, the worm 5 can drive the worm gear 10 to rotate, and the rotation direction of the worm gear 10 can adapt to different winding requirements;

[0050] Among them, a fifth fixing frame 14 is provided between the upper end of the base 1 and one side of the outside of the worm gear 10. One end of the fifth fixing frame 14 is embedded inside the worm gear 10 and is rotatably connected with the inside of the worm gear 10. The fifth fixing frame 14 is fixedly welded to the upper end of the base 1. Through the support of the fifth fixing frame 14 for the worm gear 10, the worm gear 10 is in the center position of the cable winding, which is convenient for winding the cable core wrapped with cross-linked polyethylene, and is convenient for the cable core to have the required winding strength and winding angle;

[0051] In order to increase the contact area between the worm gear 10 and the cable and adapt to different winding diameter requirements, clamping pieces 12 are provided at both the upper and lower ends of the side of the worm gear 10 facing the second fixing frame 6. Bidirectional threaded rods 13 are provided through both sides of the two clamping pieces 12. The outside of the bidirectional threaded rod 13 is in threaded cooperation with the penetration position of the clamping piece 12. By driving the bidirectional threaded rod 13, the clamping pieces 12 can be driven to move relatively, and the relative movement of the clamping pieces 12 can clamp the wound cable core;

[0052] In addition, fourth fixing frames 11 are provided at both the upper and lower ends of the bidirectional threaded rod 13, and the fourth fixing frames 11 are fixedly welded to the side surface of the worm gear 10. The fourth fixing frames 11 are rotatably connected to one end of the bidirectional threaded rod 13. After winding the cable core with a pair of clamping pieces 12, clamping the winding position and rotating can make the clamping pieces 12 twist the cable winding position to adapt to different additional winding requirements;

[0053] In order to fix the worm 5, both ends of the worm 5 are arranged on the side surface of the adjusting and fixing mechanism 3 through the first fixing frame 4, and the adjusting and fixing mechanism 3 is fixedly welded to the first fixing frame 4. The first fixing frame 4 is rotatably connected to the worm 5. After being driven by a motor, the worm 5 rotates under the support of the first fixing frame 4, rotates and drives the worm gear 10 to rotate, and the rotation of the worm gear 10 can additionally twist the wound cable core.

[0054] Working principle: According to the number of cores wrapped with cross-linked polyethylene required during the stranding of the power cable core, the required mounting rings 7 are additionally installed. The mounting rings 7 are sequentially attached and installed on the sides of the inner fixing rings 15 of the second fixing frame 6. When the mounting ring 7 is connected to the fixing ring 15, the first extension block 22 protruding from the connecting block 19 inside the mounting ring 7 is inserted into the second installation groove 21 of the connecting block 19 inside the fixing ring 15. When two mounting rings 7 are connected, the first extension block 22 protruding from the connecting block 19 inside one mounting ring 7 is inserted into the second installation groove 21 of the connecting block 19 inside the other mounting ring 7. After the screwdriver passes through the threaded groove 25 at the rear end of the connecting block 19 inside the mounting ring 7, the screwdriver enters the reserved groove 24 and contacts the bolt 23 inside the reserved groove 24, causing the bolt 23 to extend from the position of the first extension block 22, so that the bolt 23 contacts the inside of the threaded groove 25 adjacent to the position where the first extension block 22 is inserted. The additionally installed mounting ring 7 at the back is fixed through the threaded fit between the threaded groove 25 and the bolt 23. Before the bolt 23 is fully tightened and the mounting ring 7 is fixed, the angle of the internal connecting strip 20 of the mounting ring 7 is pre-adjusted. The position of the connecting strip 20 corresponds to the position where the subsequent connecting strip 20 penetrates the core wrapped with cross-linked polyethylene. After the angle of the connecting strip 20 inside the mounting ring 7 is adjusted, the bolt 23 is fully tightened. After the mounting ring 7 is fixed, the required fixing frame 32 needs to be installed on the surface of the connecting strip 20. According to the different winding position requirements of the cores wound inside the fixing frame 32, bolts penetrate the four corner positions of the fixing frame 32 and are then inserted into the mounting holes 31 evenly distributed longitudinally inside the connecting strip 20 to realize the fixation of the fixing frame 32. The core wrapped with cross-linked polyethylene passes through between the first clamping rod 33 and the second clamping rod 34 inside the fixing frame 32. At the same time, the one-way threaded rod 36 is rotated so that the first clamping rod 33 clamps the penetrated core towards the second clamping rod 34. After all the cores penetrating inside the fixing ring 15 and the mounting ring 7 are fixed at the required angles, the motor corresponding to the gear 17 is started. The rotation of the gear 17 can drive the fixing ring 15 to rotate through the tooth grooves 16, and the rotation of the fixing ring 15 can drive the sequentially connected mounting rings 7 on the side and the internally fixed cores to rotate and wind. After the wound cores are pressed and transmitted through the adjusting and fixing mechanism 3, the winding frame 2 rotates and winds up the wound cable.

After the angle is adjusted, the bolt (23) is fully tightened; Step 5: After the bolt penetrates through the four corner positions of the fixed frame (32), it is embedded in the mounting holes (31) evenly distributed longitudinally inside the connecting bar (20); Step 6: The wire core passes through between the first clamping rod (33) and the second clamping rod (34) inside the fixed frame (32), and at the same time, the one-way threaded rod (36) is rotated so that the first clamping rod (33) clamps the penetrated wire core towards the second clamping rod (34); Step 7: The rotation of the gear (17) can drive the fixed ring (15) to rotate through the tooth groove (16), and the mounting rings (7) connected in sequence on the side and the wire core fixed inside rotate and are wound; Step 8: After the wound wire core is pressed and transmitted through the adjusting and fixing mechanism (3), the wire winding frame (2) rotates and winds up the wound cable.
