Description

Technical Field

[0001] The invention relates to the technical field of cable twisting equipment, in particular to a cable twisting device for intelligent power distribution network emergency repair and straightening. Background Art

[0002] The power system is the foundation of a society's economic development, order, and public welfare. When a natural disaster or external force causes a power outage, the power supply must be restored in the shortest possible time. During the power repair process, the damaged cables need to be replaced. Since the damaged cables vary in length and the repair time is tight, a cable twisting device is usually used to twist the cables to produce cables of the appropriate length for replacement. The cable twisting device can quickly and efficiently complete the cable twisting work, reducing manual operation time and enabling repair personnel to restore power supply more quickly.

[0003] However, during the twisting process, due to the different specifications of the cables, the friction tension of each reel cannot be completely consistent. Excessive cable tension can easily lead to cable breakage, resulting in twisting interruption and increasing repair costs and time. Too little tension will make the twisted cables too loose, affecting electrical performance and mechanical strength. Due to the lack of a precise tension adjustment mechanism, it is difficult for staff to control the tension, which not only increases the probability of problems occurring in the cable twisting process, but also affects the twisting quality and the stable operation of the equipment.

When the driving rod rotates, the adjustment ring moves and pushes the connecting rod to make the connecting groove abut against the cable body, thereby realizing effective control of the cable tension.

The design of the connecting frame allows for synchronous adjustment of the second support brackets on the two sets of cross-shaped rotating disks, ensuring stability and consistency during the straightening process. The use of synchronization rods ensures the synchronized rotation of all components, avoiding cable entanglement and kinking caused by asynchronous operation. The entire device is compact and operates smoothly, ensuring long-term stable operation and providing reliable support for emergency power repairs. BRIEF DESCRIPTION OF THE DRAWINGS

The cable twisting mechanism includes two groups of straightening assemblies 3, a tension adjustment assembly 4 connected to the straightening assembly 3, and a twisting assembly 6 fixedly connected to the top of the support base 1, wherein the straightening assembly 3 is symmetrically arranged in two groups, and the two groups of straightening assemblies 3 are connected to the wire-releasing assembly 2. The straightening assembly 3 is fixed, and a driving assembly 5 for adjusting the straightening assembly 3 and the tension adjusting assembly 4 is further provided in one group. The pay-off assembly 2 includes a pay-off drum 21, and the pay-off drum 21 is rotatably connected to the support plate 11. The side of the support plate 11 away from the pay-off drum 21 is fixedly connected with a driving motor for driving the pay-off drum 21 to rotate. The pay-off drum 21 is fixedly connected to the side away from the support plate 11 with multiple groups of pay-off racks 22. Each group of pay-off racks 22 is rotatably connected to a winding roller, and each group of winding rollers is wound with a cable body 2. 8. Each pay-off frame 22 is also fixedly connected to a first servo motor 23. The output end of each first servo motor 23 is fixed to the winding roller on the adjacent pay-off frame 22. The pay-off drum 21 is also fixedly connected to the side away from the support plate 11 with a first synchronization rod 24. The end of the first synchronization rod 24 away from the pay-off drum 21 is connected to the adjacent straightening assembly 3. The stranding assembly 6 includes a first connecting seat 61 and a second connecting seat 66 fixedly connected to the top of the support seat 1. The stranding drum 62 is rotatably connected to the first connecting seat 61. The stranding drum Multiple groups of synchronization blocks 63 are fixedly connected to the inner wall of 62. Each group of synchronization blocks 63 is provided with a connection hole 64 for the cable body 28 to pass through. A synchronization disk 65 is also fixedly connected to the side of the synchronization blocks 63 away from the twisting disk 62. The synchronization disk 65 is fixed to the third synchronization rod 26. The top of the second connection seat 66 is fixedly connected to a connection block 67. The connection block 67 is provided with a twisting opening. Multiple groups of cable bodies 28 pass through the two groups of straightening components 3, the tension adjustment component 4 and the connection holes 64 in sequence and extend into the connection block 67.

[0041] Specifically, when in use, first install the winding roller with the cable body 28 wound on it in the pay-off frame 22, connect the winding roller to the output end of the first servo motor 23, and after multiple winding rollers are installed, pull one end of the cable body 28 from the winding roller and pass it through the two groups of straightening components 3, the tension adjustment component 4 and the twisting component 6 in sequence, start the driving motor on the support plate 11, multiple groups of first servo motors 23 and the driving component 5, and drive the pay-off drum 21 to rotate through the driving motor on the support plate 11, and the pay-off drum 21 drives multiple groups of pay-off frames 22 to rotate at the same time, and drives the two groups of straightening components 3 to rotate at the same time through the first synchronization rod 24 and the second synchronization rod 25. When the pay-off frame 22 rotates with the pay-off drum 21, the first servo motor 23 is started, driving the winding roller to rotate, so that the cable body 28 on the winding roller is moved out, and the twisting work is continuously performed;

[0042] The cable body 28 passing through the two sets of straightening components 3 is straightened by the two sets of straightening components 3, so that the cable body 28 can fit better when twisted, reducing the gap, making the stress distribution of the cable more uniform after twisting, and helping to improve the overall mechanical strength of the cable after twisting;

[0043] After being straightened, the multiple groups of cable bodies 28 pass through the connecting holes 64 in sequence. Driven by the third synchronization rod 26, the synchronization disk 65 drives the twisting disk 62 to rotate in the first connecting seat 61. Through the rotation, the multiple groups of cable bodies 28 are twisted together. The twisted cable bodies 28 are removed through the twisting opening on the connecting block 67, completing the twisting work.

[0044] For example 2, please refer to Figure 1-Figure 7The straightening assembly 3 includes a cross rotating disk 31, and both sides of the cross rotating disk 31 are fixedly connected to a connecting disk 32. The two connecting disks 32 on the same group of cross rotating disks 31 are fixed to the cross rotating disk 31 by bolts. The two cross rotating disks 31 are provided with multiple groups of through holes 33 for the cable body 28 to pass through. The facing surfaces of the two cross rotating disks 31 are provided with multiple groups of first support frames 34 and second support frames 35. Each group of first support frames 34 and second support frames 35 are rotatably connected to a straightening roller. The multiple groups of first support frames 34 are respectively fixedly connected to the adjacent cross rotating disks 31, and the multiple groups of second support frames 35 are respectively slidably connected to the facing surfaces of the two groups of cross rotating disks 31, and each group of first support frames 34 and second support frames 35 are located on both sides of adjacent through holes 33. A connecting frame 36 is also fixedly connected between the two cross rotating disks 31, and both ends of each group of connecting frames 36 are connected to the two adjacent groups of second support frames The two cross rotating disks 31 are fixed with each other, and the facing surfaces of the two groups of cross rotating disks 31 are provided with connecting holes 37 for sliding of multiple groups of second support frames 35, one of which is fixed to the first synchronous rod 24 on one side of the connecting disk 32 close to the first synchronous rod 24, and the second synchronous rod 25 is fixedly connected between the facing surfaces of the two cross rotating disks 31, and the two ends of the second synchronous rod 25 are respectively fixed to the connecting disks 32 on the facing surfaces of the two cross rotating disks 31. The two cross rotating disks 31 are connected through the second synchronous rod 25, and the third synchronous rod 26 is also fixedly connected to the connecting disk 32 away from the pay-off assembly 2, and the other end of the third synchronous rod 26 is connected to the twisting assembly 6. A limiting groove 27 is also provided on the third synchronous rod 26, and the tension adjustment assembly 4 is slidably connected to the limiting groove 27. The driving assembly 5 is arranged in the cross rotating disk 31 away from the pay-off assembly 2, and the output end of the driving assembly 5 passes through the cross rotating disk 31 and is connected to the tension adjustment assembly 4;

[0045] Specifically, when twisting, first, one end of the plurality of cable bodies 28 is passed through the through-holes 33 on the two cross-rotating disks 31, and the driving assembly 5 in the cross-rotating disk 31 is started. The driving assembly 5 drives the second support frame 35 to move toward the direction of the cable body 28 in the through-hole 33, so that the second support frame 35 contacts the cable body 28 and pushes the cable body 28 to contact the first support frame 34. The cable body 28 is clamped by the first support frame 34 and the second support frame 35, so that when the cable body 28 is twisted, the cable body 28 is straightened by the clamping of the first support frame 34 and the second support frame 35.

[0046] When the second support frame 35 on one group of cross rotating disks 31 is being adjusted, the second support frame 35 on the other group of cross rotating disks 31 moves synchronously driven by the connecting frame 36, so that the second support frames 35 on the two groups of cross rotating disks 31 can be adjusted synchronously. At the same time, when the pay-off disk 21 rotates, the pay-off disk 21 can drive one of the cross rotating disks 31 to rotate through the first synchronization rod 24, and the two cross rotating disks 31 rotate synchronously through the second synchronization rod 25, so that the two cross rotating disks 31 can rotate simultaneously with the pay-off disk 21, thereby ensuring the synchronization of twisting.

[0047] For example three, please refer to Figure 1-Figure 7 The driving assembly 5 includes a second servo motor 51, which is fixedly connected to the cross rotating disk 31 away from the pay-off assembly 2. The output end of the second servo motor 51 is fixedly connected to an incomplete gear 52, and the side of the incomplete gear 52 away from the second servo motor 51 is fixedly connected to a synchronous gear 53. The side of the synchronous gear 53 away from the incomplete gear 52 is rotatably connected to the cross rotating disk 31 through a rotating shaft. The driving assembly 5 also includes multiple groups of driving gears 54 rotatably connected to the cross rotating disk 31. The multiple groups of driving gears 54 are evenly distributed on the outside of the incomplete gear 52, and the multiple groups of driving gears 54 alternately mesh with the incomplete gear 52. The cross rotating disk 31 is also fixedly connected to a multiple group of limiting sliding blocks 55, and each group of limiting sliding blocks 55 is slidably connected to the same The step rack 56 and the plurality of synchronous racks 56 are respectively meshed with the adjacent driving gears 54. The end of each synchronous rack 56 away from the driving gear 54 is fixedly connected to a connecting plate 59. The plurality of connecting plates 59 are respectively located on adjacent communicating holes 37, and the plurality of connecting plates 59 are respectively connected to the adjacent second support frames 35. The driving assembly 5 also includes a linkage gear 57 rotatably connected to the cross rotating disk 31. The linkage gear 57 is meshed with the synchronous gear 53. The end of the linkage gear 57 close to the second servo motor 51 is fixedly connected to a connecting rod, and the other end of the connecting rod passes through the cross rotating disk 31 and extends to the outside of the cross rotating disk 31. The extended end of the connecting rod is fixedly connected to a driving rod 58. The driving rod 58 is connected to the tension adjustment assembly 4, and a bidirectional thread groove is provided on the driving rod 58.

[0048] Specifically, when adjusting the second support frame 35, the second servo motor 51 is first started. The second servo motor 51 drives the incomplete gear 52 and the synchronous gear 53 to rotate. When the teeth on the synchronous gear 53 rotate to engage with the adjacent driving gear 54, the driving gear 54 is simultaneously driven to rotate. The driving gear 54 drives the synchronous rack 56 to move on the limiting sliding block 55. When the synchronous rack 56 moves, it pushes the adjacent second support frame 35 to slide in the communicating hole 37 through the connecting plate 59, so that the distance between the second support frame 35 and the first support frame 34 is adjusted.

[0049] When the incomplete gear 52 rotates, the synchronous gear 53 rotates at the same time. The synchronous gear 53 continues to rotate to push the linkage gear 57 to rotate, so that the linkage gear 57 drives the driving rod 58 to rotate, and the tension adjustment component 4 is adjusted through the driving rod 58. Through the synchronous adjustment of the tension adjustment component 4 and the second support frame 35, the tension adjustment component 4 can cooperate with the second support frame 35 to adjust the tension of the cable body 28 of different thicknesses.

[0050] For example 4, please refer to Figures 1-9 The tension adjustment assembly 4 includes two groups of adjustment rings 41, both of which are slidably connected to the third synchronization rod 26, and the two groups of adjustment rings 41 are respectively threadedly connected to the bidirectional thread grooves on the drive rod 58. The two groups of adjustment rings 41 are also hinged to multiple groups of first connecting rods 42. The tension adjustment assembly 4 also includes multiple second connecting rods 43, and one end of each second connecting rod 43 close to the adjustment ring 41 is hinged to the adjacent first connecting rod 42 on the two groups of adjustment rings 41. The end of each second connecting rod 43 away from the adjustment ring 41 is provided with a connection groove 44 for supporting the cable body 28.

[0051] When the driving rod 58 rotates, the driving rod 58 simultaneously drives the two adjusting rings 41 to move toward each other, so that the distance between the two adjusting rings 41 is reduced, and the first connecting rod 42 on the two adjusting rings 41 extends in the direction away from the adjusting ring 41 under the push of the adjusting ring 41, so that the second connecting rod 43 simultaneously extends in the direction away from the adjusting ring 41, so that the connecting groove 44 abuts against the cable body 28. When the cable body 28 is thinner, the range of movement of the second support frame 35 is larger, and the distance between the two adjusting rings 41 is smaller, so that the tension adjustment assembly 4 can be adjusted synchronously with the movement of the second support frame 35 to adapt to the use of cable bodies 28 of different thicknesses.

[0052] The working principle of the present invention is:

[0053] When in use, first install the winding roller with the cable body 28 wound on it in the pay-off frame 22, connect the winding roller to the output end of the first servo motor 23, and after multiple winding rollers are installed, pull one end of the cable body 28 from the winding roller and pass it through the two groups of straightening components 3, the tension adjustment component 4 and the twisting component 6 in sequence, start the driving motor on the support plate 11, the multiple groups of first servo motors 23 and the second servo motors 51, and drive the pay-off reel 21 to rotate through the driving motor on the support plate 11. The pay-off reel 21 drives the multiple groups of pay-off frames 22 to rotate at the same time, and drives the two groups of straightening components 3 to rotate at the same time through the first synchronization rod 24 and the second synchronization rod 25. When the pay-off frame 22 rotates with the pay-off reel 21, the first servo motor 23 is started, driving the winding roller to rotate, so that the cable body 28 on the winding roller is moved out, and the twisting work is continuously performed;

[0054] When twisting, first, one end of the multiple cable bodies 28 is passed through the through-holes 33 on the two cross-rotating disks 31, and the second servo motor 51 is started. The second servo motor 51 drives the incomplete gear 52 and the synchronous gear 53 to rotate. When the teeth on the synchronous gear 53 rotate to engage with the adjacent driving gear 54, the driving gear 54 is simultaneously pushed to rotate. The driving gear 54 drives the synchronous rack 56 to move on the limiting sliding block 55. When the synchronous rack 56 moves, the adjacent second support frame 35 is pushed to slide in the communicating hole 37 through the connecting plate 59, so that the distance between the second support frame 35 and the first support frame 34 is adjusted;

[0055] When the driving rod 58 rotates, the driving rod 58 simultaneously drives the two adjusting rings 41 to move toward each other, reducing the distance between the two adjusting rings 41. The first connecting rod 42 on the two adjusting rings 41 extends in a direction away from the adjusting rings 41 under the push of the adjusting rings 41, causing the second connecting rod 43 to extend in a direction away from the adjusting rings 41 at the same time, so that the connecting groove 44 abuts against the cable body 28.

[0056] When the second support frame 35 on one set of cross rotating disks 31 is adjusted, the second support frame 35 on the other set of cross rotating disks 31 is driven by the connecting frame 36 to move synchronously, so that the second support frames 35 on the two sets of cross rotating disks 31 can be adjusted synchronously. At the same time, when the pay-off drum 21 rotates, the pay-off drum 21 can drive one of the cross rotating disks 31 to rotate through the first synchronization rod 24, and the two cross rotating disks 31 rotate synchronously through the second synchronization rod 25, so that the two cross rotating disks 31 can rotate simultaneously with the pay-off drum 21, thereby ensuring the synchronization of twisting.

[0057] As the two cross-shaped rotating disks 31 continuously rotate, the cable body 28 is continuously pulled out from the winding roller. When the cable body 28 passes between the second support frame 35 and the first support frame 34, the straightening rollers in the second support frame 35 and the first support frame 34 are simultaneously driven to rotate. The rotation of the straightening rollers squeezes the cable body 28, effectively eliminating the bending and twisting of the cable body 28.

[0058] The cable body 28 passing through the two sets of straightening components 3 is straightened by the two sets of straightening components 3, so that the cable body 28 can fit better when twisted, reducing the gap, making the stress distribution of the cable more uniform after twisting, and helping to improve the overall mechanical strength of the cable after twisting;

[0059] After being straightened, the multiple groups of cable bodies 28 pass through the connecting holes 64 in sequence.
