[0014] This utility model provides a tension-adjustable wire rope double-twisting machine. During wire rope production, the inconvenience of tension adjustment leads to inconsistent tensions in multiple wire ropes, resulting in tension imbalance. This directly affects the tensile strength, torsion, and bending properties of the wire rope, potentially causing fatigue damage, premature failure of friction pads, and rope breakage – serious accidents. To achieve uniform tension adjustment and improve wire rope production quality, during wire rope twisting, operators adjust the tension according to production needs. The first servo motor is activated, the rotor drives the first gear, which in turn drives the rack, which in turn drives the movable rod. Simultaneously, the first gear drives the first gear ring, which in turn drives multiple first gears to rotate synchronously. This causes the multiple movable rods to move synchronously, which in turn moves the fixed frame and the first roller, causing the wire rope on the first roller to expand outwards or contract inwards. Expanding outwards increases tension, while contracting inwards decreases tension. Synchronous tension adjustment across multiple wire ropes results in a more uniform tension distribution, improving production quality. Attached Figure Description

[0027] A movable groove 14 is provided on one side of the through hole 12. A rack 15 is fixedly provided on one side of the movable rod 13. The rack 15 is movably inserted into the movable groove 14. An array of rotating rods 16 are arranged in a ring array inside the hollow ring 11 and rotated by bearings. The rotating rods 16 are perpendicular to the movable rod 13. The number of rotating rods 16 is the same as that of the through holes 12 and they are arranged accordingly. A first gear 17 is fixedly provided on the circumference of the rotating rod 16. The first gear 17 meshes with the teeth of the rack 15. Two sets of first toothed rings 18 are rotatably provided on one side of the circumference of the hollow ring 11 and mesh with the teeth of the first gear 17. The hollow ring 11... A first servo motor 19 is fixedly mounted on the outer side of the hollow ring 11 via a fixing bracket. One of the rotating rods 16 rotates and extends through the outer side of the hollow ring 11. The output end of the first servo motor 19 is fixedly connected to one end of the rotating rod 16 via a coupling. A fixing frame 20 is fixedly mounted on one end of the movable rod 13 on the outer circumferential surface of the hollow ring 11. Two sets of first rollers 21 are mounted inside the fixing frame 20 in a mirror-like manner via the rotating rod. A limit block 22 is fixedly mounted on one end of the movable rod 13 on the outer inner circumferential surface of the hollow ring 11. A third fixing plate 28 is fixedly mounted on one side of the top of the base 1. A hub tube 29 is fixedly mounted on and extends through the third fixing plate 28. The two ends of the hub tube 29 are arc-shaped. The inner circumferential surface of the hub tube 29 is fixedly equipped with an array of universal balls 30 in a ring array. The central axes of the fixed disk 3, turntable 8, hollow ring 11, hub tube 29, and circular hole 5 are aligned.

The output end of the second servo motor 23 is fixedly mounted with a rotating shaft via a coupling, and a second gear 24 is fixedly mounted on the other end of the rotating shaft. A second toothed ring 25 is fixedly mounted on the circumferential surface of the turntable 8. The teeth of the second toothed ring 25 mesh with those of the second gear 24. During operation, when producing wire rope, due to the inconvenience of tension adjustment, the tension of the array of wire ropes is uneven, resulting in an imbalance of wire rope tension, which directly affects... The tensile strength, torsion, and bending properties of the wire rope are affected, which can lead to fatigue damage, premature scrapping of friction pads, and major accidents such as rope breakage. In order to uniformly adjust the tension of the wire rope and improve the production quality of the wire rope, the workers first extract multiple strands of wire rope from the outside of the external wire rope storage device, pass them through the first through hole 4 on the fixed plate 3 and the second through hole 9 on the turntable 8, and then pass the array of wire ropes through the two sets of first rollers 21 at the corresponding positions. Then, the wire rope core on the central shaft passes through the round hole 5 at the center of the fixed plate 3 and the turntable 8, and then the multiple strands of wire rope are integrated into one, which is then passed out through the collector tube 29. Finally, the front end of the integrated wire rope is fixed to the external receiving roller.When twisting the wire rope, the motor on the outer receiving roller is started to rotate the outer receiving roller, which takes the wire rope in place. At the same time, the wire rope can be pulled out from the external wire rope storage device. Then, the operator needs to adjust the tension of the wire rope according to production needs. The first servo motor 19 is started, the rotor 16 drives the first gear 17 to rotate, the first gear 17 drives the rack 15 to move, the rack 15 drives the movable rod 13 to move, and at the same time, the first gear 17 drives the first gear ring 18 to rotate. The first gear ring 18 drives the array of first gears 17 to rotate synchronously, so that the array of movable rods 13 moves synchronously. The movable rod 13 drives the fixed frame 20 and the first roller 21 to move, and at the same time, it causes the wire rope on the first roller 21 to expand outward or contract inward. The outward expansion increases tension, while the inward contraction reduces tension. Synchronously adjusting the tension of the multiple wire ropes ensures a more uniform tension distribution, improving production quality. Simultaneously, the operator starts the second servo motor 23, which drives the second gear 24 to rotate. The second gear 24 then drives the second gear ring 25, which in turn drives the turntable 8 to rotate with the moving wire ropes. Simultaneously, as the wire ropes move within the first through-hole 4 and the second through-hole 9, they drive the second roller 27 to rotate, making the movement of the wire ropes smoother and reducing wear. Finally, the multiple strands of wire rope are twisted into one. The twisted wire rope slides within the collector tube 29 with the assistance of the universal ball 30, and is then collected on the external collecting roller, completing the wire rope twisting process.
[0028] Working Principle: During the production of wire ropes, the tension of multiple wire ropes is inconsistent due to the difficulty in adjusting the tension, leading to tension imbalance. This directly affects the tensile strength, torsion, bending, and other quality indicators of the wire rope, resulting in fatigue damage, premature failure of friction pads, rope breakage, and other serious accidents. To achieve uniform tension adjustment and improve the production quality of the wire ropes, workers first extract multiple strands of wire rope sequentially from the outer wire rope storage device, passing them through the first through hole 4 on the fixed plate 3 and the second through hole 9 on the turntable 8. Then, the multiple strands of wire rope are... The wire rope passes between the two sets of first rollers 21 at corresponding positions. Then, the wire rope core on the central shaft passes through the circular hole 5 at the center of the fixed plate 3 and the turntable 8. Multiple strands of wire rope are then combined into one, passed through the collector tube 29, and finally the front end of the combined wire rope is fixed to the outer receiving roller. When twisting the wire rope, the motor on the outer receiving roller is started to rotate it, winding the wire rope. Simultaneously, the wire rope can be pulled out from the external wire rope storage device. Afterwards, the operator needs to adjust the tension of the wire rope according to production needs by starting the first servo motor. 19. The rotating rod 16 drives the first gear 17 to rotate, the first gear 17 drives the rack 15 to move, the rack 15 drives the movable rod 13 to move, and at the same time, the first gear 17 drives the first gear ring 18 to rotate, the first gear ring 18 drives the array of first gears 17 to rotate synchronously, so that the array of movable rods 13 move synchronously. The movable rod 13 drives the fixed frame 20 and the first roller 21 to move, and at the same time drives the steel wire rope on the first roller 21 to expand outward or contract inward. Expanding outward increases its tension, and conversely, contracting inward decreases its tension. The array of steel wire ropes synchronously adjusts the tension, making the tension distribution more uniform and improving production efficiency. To improve production quality, the operator starts the second servo motor 23, which drives the second gear 24 to rotate. The second gear 24 drives the second gear ring 25 to rotate, and the second gear ring 25 drives the turntable 8 to rotate with the moving steel wire rope. At the same time, when the steel wire rope moves in the first through hole 4 and the second through hole 9, it drives the second roller 27 to rotate, making the movement of the steel wire rope smoother and reducing wear. Then, the multiple strands of steel wire rope are twisted into one. The twisted steel wire rope slides in the collector tube 29 with the cooperation of the universal ball 30, and is then collected on the external collecting roller, completing the twisting work of the steel wire rope.
