[0002] In the cable cabling process, especially for complex composite cables, pay-off frames are frequently used to meet cabling requirements. Many cable cabling processes require pay-off frames with untwisting capabilities to ensure cable quality. Existing automatic untwisting pay-off frames mostly use active drive devices to achieve cable untwisting. These active drive devices are generally motors, resulting in high equipment and maintenance costs. Furthermore, the pay-off frames are heavy, inconvenient to move, and require relocation of power supplies, making their application inflexible, inconvenient, and difficult to promote.

The second shaft has a through hole along its axial direction. The first shaft is rotatably connected to the bracket via a second bearing, and the second shaft is rotatably connected to the bracket via a third bearing. A clamping assembly, disposed within the rotating frame, is used to coaxially fix the cable shaft to the first shaft and is rotatable relative to the rotating frame; The guide assembly is symmetrically arranged on both sides of the cable shaft within the rotating frame. The guide assembly is used to guide the cable wound on the cable shaft so that the cable passes through one or the other side of the rotating frame and then exits through the cable hole. A transmission assembly, disposed between the bracket and the rotating frame, is used to drive the rotating frame to rotate as the cable shaft rotates, such that the rotation direction of the rotating frame is opposite to the rotation direction of the cable shaft. The transmission assembly includes a drive gear fixedly sleeved on the first shaft within the rotating frame. First driven gears are symmetrically meshed on both sides of the drive gear. A third shaft is fixedly connected to the first driven gear. The third shaft is rotatably connected to the rotating frame via a fourth bearing. A fixed gear is fixedly disposed on the bracket at the outer periphery of the first shaft. Second driven gears are symmetrically meshed on both sides of the fixed gear. The second driven gears are fixedly sleeved on the third shaft in a corresponding manner.

[0005] Furthermore, the bracket includes a front bracket and a rear bracket; The front support includes a front support base, and front support legs are symmetrically fixedly connected to both sides of the front support base. The second shaft is rotatably connected to the front support base through a third bearing. The rear support includes a rear support base, and rear support legs are symmetrically fixedly connected to both sides of the rear support base. The first shaft is rotatably connected to the rear support base through a second bearing.

[0006] Furthermore, the clamping assembly includes a fixed center and a movable center; The fixed center is disposed within the rotating frame and is coaxial with the first shaft. The fixed center is fixedly connected to the end of the first shaft through a clamping plate. A limit rod is fixedly disposed on one side of the fixed center on the clamping plate. Limit holes are respectively opened at both ends of the cable shaft corresponding to the limit rod.

[0007] Furthermore, the fixed tip is a frustum shape with an outer diameter that gradually decreases in the direction away from the first shaft; the movable tip is a frustum shape with an outer diameter that gradually decreases in the direction away from the lead screw.

[0008] Furthermore, the guiding assembly includes a first guide wheel, a second guide wheel, a third guide wheel, and a guide rod; the first guide wheel is disposed within the rotating frame on one side of the cable shaft, the second guide wheel is disposed on the side of the first guide wheel near the second shaft, the line connecting the first guide wheel and the second guide wheel is parallel to the axis of the cable shaft, the third guide wheel is disposed near the side of the threaded hole, and the guide rod is fixedly disposed within the rotating frame between the first guide wheel and the cable shaft, and is parallel to the axis of the cable shaft.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0015] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] Please refer to Figures 1-4 An embodiment of the present invention provides a mechanical automatic untwisting cable laying rack, comprising: Bracket 1; A rotating frame 2 is mounted on a bracket 1. One end of the frame is rotatably connected to a first shaft 21 via a first bearing 23, and the other end is fixedly connected to a second shaft 22 coaxial with the first shaft 21. The second shaft 22 has a wire hole 24 along its axial direction. The first shaft 21 is rotatably connected to the bracket 1 via a second bearing 25, and the second shaft 22 is rotatably connected to the bracket 1 via a third bearing 26. The clamping assembly 3 is disposed inside the rotating frame 2 and is used to fix the cable shaft 6 coaxially with the first shaft 21, and is rotatable relative to the rotating frame 2; Guide components 4 are symmetrically arranged on both sides of the cable shaft 6 inside the rotating frame 2. The guide components 4 are used to guide the cable 7 wound on the cable shaft 6 so that the cable 7 passes through one side or the other side inside the rotating frame 2 and then passes through the wire hole 24 for output. The transmission assembly 5 is disposed between the bracket 1 and the rotating frame 2, and is used to drive the rotating frame 2 to rotate with the rotation of the cable shaft 6, and to make the rotation direction of the rotating frame 2 opposite to the rotation direction of the cable shaft 6. The transmission assembly 5 includes a drive gear 51 disposed inside the rotating frame 2 and fixedly sleeved on the first shaft 21. The drive gear 51 is symmetrically meshed with a first driven gear 52 on both sides. The first driven gear 52 is fixedly connected to a third shaft 53. The third shaft 53 is rotatably connected to the rotating frame 2 through a fourth bearing 54. A fixed gear 55 is fixedly disposed on the bracket 1 at the outer periphery of the first shaft 21. The fixed gear 55 is symmetrically meshed with a second driven gear 56 on both sides. The second driven gear 56 is fixedly sleeved on the third shaft 53 one-to-one.

[0017] In this embodiment, before the cable feeding frame feeds the cable, the cable spool 6 is first clamped and fixed to the first shaft 21 by the clamping assembly 3, and then the cable 7 on the cable spool 6 is guided by the guide assembly 4 and output through the feeding hole 24, and the cable spool 6 is installed.

[0018] When the cable is laid, the cable 7 is pulled forward by the cable winch. When the cable 7 is continuously output under the traction force, the cable shaft 6 rotates accordingly. The cable shaft 6 drives the first shaft 21 to rotate, and the first shaft 21 drives the drive gear 51 to rotate. The drive gear 51 drives the second driven gear 56 to rotate through the first driven gear 52 and the third shaft 53. With the cooperation of the fixed gear 55, the two second driven gears 56 rotate around the fixed gear 55, thereby driving the rotating frame 2 to rotate in the opposite direction to the cable shaft 6 with the first shaft 21 as the axis.

[0019] The rotating frame 2 drives the output cable 7 to rotate, realizing the automatic unwinding of the cable 7. The unwinding speed can be changed by changing the size ratio of the driving gear 51 to the first driven gear 52 or the size ratio of the second driven gear 56 to the fixed gear 55 to meet different cabling requirements.

[0020] The cable laying frame of this application converts traction force into rotational force of the rotating frame 2. The rotating frame 2 does not require active driving equipment, which reduces equipment cost, facilitates maintenance, and reduces the weight of the equipment. It is flexible and convenient to use and has extremely high promotional value.

[0021] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, bracket 1 includes a front bracket and a rear bracket; The front support includes a front support 11, with front support legs 12 fixedly connected symmetrically on both sides of the front support 11, and a second shaft 22 rotatably connected to the front support 11 via a third bearing 26. The rear support includes a rear support 13, with rear support legs 14 fixedly connected symmetrically on both sides of the rear support 13. The first shaft 21 is rotatably connected to the rear support 13 through the second bearing 25.

[0022] In this embodiment, the support 1 has a simple structure and provides stable support. Preferably, the two front support legs 12 and the two rear support legs 14 are respectively in a V-shape, which further improves the stability of the support.

[0023] In a preferred embodiment, such as Figure 3 As shown, the clamping assembly 3 includes a fixed center 31 and a movable center 32; The fixed tip 31 is set inside the rotating frame 2 and is coaxial with the first shaft 21. The fixed tip 31 is fixedly connected to the end of the first shaft 21 through the clamping plate 33. A limit rod 34 is fixedly set on one side of the fixed tip 31 on the clamping plate 33. Limit holes are opened at both ends of the cable shaft 6 corresponding to the limit rod 34. A support plate 35 is fixedly installed inside the rotating frame 2 on the side of the fixed tip 31 away from the first shaft 21. A lead screw 36 coaxial with the first shaft 21 is threaded onto the support plate 35. One end of the lead screw 36 near the fixed tip 31 is rotatably connected to the movable tip 32 through the fifth bearing 37, and the other end is fixedly connected to a handwheel 38.

[0024] In this embodiment, when clamping the cable shaft 6, firstly, the screw 36 is rotated by the handwheel 38 to increase the distance between the fixed tip 31 and the movable tip 32. Then, the cable shaft 6 is placed between the fixed tip 31 and the movable tip 32. The fixed tip 31 is aligned and inserted into one end of the cable shaft 6, and the limiting rod 34 is inserted into the corresponding limiting hole to prevent relative rotation between the cable shaft 6 and the first shaft 21. Then, the handwheel 38 is rotated to insert the movable tip 32 into the other end of the cable shaft 6, thus completing the clamping and fixing of the cable shaft 6. The operation is convenient and the fixing is stable.

[0025] In a preferred embodiment, such as Figure 3 As shown, the fixed tip 31 is a frustum-shaped cone with its outer diameter gradually decreasing in the direction away from the first shaft 21; the movable tip 32 is also a frustum-shaped cone with its outer diameter gradually decreasing in the direction away from the lead screw 36. This facilitates the insertion of the fixed tip 31 and the movable tip 32 into the center hole of the cable shaft 6 and improves the fixing effect.

[0026] In a preferred embodiment, such as Figure 3 As shown, the guide assembly 4 includes a first guide wheel 41, a second guide wheel 42, a third guide wheel 43, and a guide rod 44. The first guide wheel 41 is disposed inside the rotating frame 2 on one side of the cable shaft 6. The second guide wheel 42 is disposed on the side of the first guide wheel 41 near the second shaft 22. The line connecting the first guide wheel 41 and the second guide wheel 42 is parallel to the axis of the cable shaft 6. The third guide wheel 43 is disposed near the side of the threaded hole 24. The guide rod 44 is fixedly disposed inside the rotating frame 2 between the first guide wheel 41 and the cable shaft 6, and is parallel to the axis of the cable shaft 6.

[0027] In this embodiment, the cable 7 on the cable reel 6 first passes through the guide rod 44, then through the first guide wheel 41, and then through the second guide wheel 42 and the third guide wheel 43 before exiting through the threading hole 24. After being guided, the cable 7 can rotate together with the rotating frame 2, thereby achieving untwisting. The guide assembly 4 has a reasonable structural design, ensuring the automatic untwisting of the cable 7.
