Description

Technical Field

[0001] This invention relates to the field of steel wire rope processing equipment technology, specifically to a constant tension twisting device for ultra-high strength steel wire rope strands. Background Technology

[0002] Ultra-high strength steel wire ropes are widely used in high-end heavy-duty applications such as large-scale mining hoisting, deep-sea engineering hoisting, high-rise building construction, and high-speed rail transportation due to their excellent tensile strength, fatigue resistance, and structural stability. Strand twisting is the core process in steel wire rope production, which directly determines the structural uniformity, mechanical properties, and finished product qualification rate of the steel wire rope. It is a key link that restricts the quality upgrade of ultra-high strength steel wire ropes.

[0003] The prior art (Chinese patent publication number: CN112458772A, publication date: 2021-03-09) discloses a twisting device for steel wire rope production, including a base plate and a rotating body. A gathering box is fixedly installed on one side of the top of the base plate. Movable rods are movably sleeved on both the front and rear sides of the gathering box. A gathering plate is fixedly installed at the rear end of the movable rod. A double-headed motor is fixedly installed at the bottom of the inner cavity of the gathering box. A movable plate is fixedly sleeved on the rear side of the movable rod. This twisting equipment for steel wire rope production uses a double-headed motor to drive the lead screws on the front and rear sides of the motor to rotate. The lead screws are connected to a movable rod via a moving plate, facilitating the movement of the movable rod along the connection point with the gathering box. This, in turn, moves the gathering plate within the gathering box, allowing for adjustments to the distance between the gathering plates on the front and rear sides of the double-headed motor. This makes the equipment suitable for twisting steel wire ropes of different thicknesses. Prior art (Chinese patent publication number: CN119083215A, publication date: 2024-12-06) discloses a spring steel wire twisting tension release mechanism, including: a drive shaft, a first winch, a second winch, a third winch, and connecting bolts. The drive shaft internally houses... The drive shaft has a through hole; the first winch has a first winch screw hole at its center, and also has a connecting screw hole and a fixed roller groove; the second winch has a second winch screw hole at its center, and also has a slider movable groove and a connecting through hole; the third winch has a second winch screw hole at its center, and also has a fixed roller groove and a connecting hole, with a first roller installed in the fixed roller groove; the connecting bolts pass sequentially through the connecting hole of the third winch, the connecting through hole of the second winch, and the locking screw hole of the first winch. By positioning the second winch between the first and third winches, the position of the slider assembly on the second winch can be adjusted, thereby effectively regulating the release of wire strand tension and ensuring the twisting quality of the wire rope.

[0004] While existing wire rope strand twisting equipment can release and adjust the tension of the wire rope, it requires active operation. During the twisting process, the tension of the wire rope changes synchronously with the twisting speed and the wire release speed, making it impossible for conventional tension adjustment mechanisms to adjust automatically in real time. This leads to an increase in the wire breakage rate during the wire twisting process, which seriously affects the production efficiency of the equipment. Summary of the Invention

Centrifugal blocks are evenly hinged between the first slip ring and the second slip ring through hinge rods, and during the rotation of the first slip ring and the second slip ring, the centrifugal blocks pull the first slip ring and the second slip ring closer together through the hinge rods under centrifugal force.

[0009] Preferably, the tension adjustment assembly further includes an adjustment wheel group that is uniformly hinged by a hinge rod, and the adjustment wheel group is supported on the outside of the steel wire. The tension of the steel wire is adjusted by the adjustment wheel group during the sliding of the first slip ring and the second slip ring.

[0010] Preferably, the yarn feeding resistance adjustment mechanism includes an air storage bladder fixedly installed between the first rotating disk and the first slip ring, a movable frame elastically slidably installed on the yarn feeding frame, and an elastic bladder fixedly connected between the first rotating disk and the movable frame, and the air storage bladder and the elastic bladder are connected by a pipe.

[0011] Preferably, during the contraction of the elastic bladder, the movable frame is pulled away from the unwinding frame, and an elastic pressure block is fixedly installed on the movable frame. The elastic pressure block is always in contact with the outer side of the unwinding wheel, and the sliding adjustment of the movable frame realizes the adjustment of the unwinding resistance of the unwinding wheel.

[0012] Preferably, the oil injection assembly includes a fixed frame fixedly installed on the collection tank, and a rotating ring is rotatably installed on the upper inner side of the fixed frame, and oil injection pipes are evenly connected on the rotating ring, with the oil injection pipes facing the steel wire. The rotating ring and the third rotating disk are fixedly connected by a bracket.

[0013] Preferably, the flow regulating component includes a regulating tube fixedly installed on the outside of the bracket, and a connecting rod is telescopically connected to the regulating tube.

[0014] Preferably, the cavity of the control tube is provided with an adjustment hole, and a flow adjustment rod is fixedly connected to one end of the connecting rod located inside the control tube. The flow adjustment rod is a frustum structure. During the movement of the connecting rod, the flow adjustment rod is driven to slide inside the adjustment hole to adjust the flow path of the oil inside the control tube. The circulating oil pipe and the oil delivery pipe are respectively connected to the left and right sides of the adjustment hole.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the constant tension twisting equipment for ultra-high strength steel wire rope strands can automatically adjust the wire tension according to the centrifugal force of rotation during the twisting process, and can simultaneously adjust the wire unwinding resistance, and can apply an appropriate amount of oil to the wire, effectively avoiding wire breakage due to excessive wire tension. The specific details are as follows. 1. The device is equipped with a first slip ring, a second slip ring, a centrifugal block, and an adjusting wheel assembly. During the twisting process, as the first and second rotating discs rotate, the first and second slip rings rotate synchronously, causing the centrifugal block connected between them to move under centrifugal force. The centrifugal block can pull the first and second slip rings to slide elastically and move closer to each other on the outside of the fixed connecting frame through the hinge rod. At the same time, the adjusting wheel assembly is adjusted through the hinge rod, so that the adjusting wheel assembly can adjust and support the steel wire, realize tension adaptation adjustment, avoid excessive centrifugal tension of the steel wire at high speed, and prevent the steel wire from being pulled outward and the tension from increasing.

[0016] 2. It is equipped with an air reservoir, an elastic bladder, and an elastic pressure block. As the first slip ring slides, it can stretch the air reservoir, causing the elastic bladder to contract, thereby pulling the movable frame away from the wire feeding frame. This reduces the pressure of the elastic pressure block on the wire feeding wheel, thereby reducing the unwinding resistance of the wire feeding wheel and further realizing the adaptive adjustment of the wire tension.

[0017] 3. Equipped with an oil injection pipe and a regulating pipe, oil can be injected into the inner side of the rotating ring via an oil pump, allowing the oil to be sprayed onto the outer side of the steel wire through the oil injection pipe. As the rotating ring rotates synchronously, the oil spraying effect can be further improved. At the same time, during the sliding of the second slip ring, the connecting plate can drive the connecting rod to move synchronously, thereby adjusting the position of the flow regulating rod in the regulating hole through the connecting rod, thus changing the oil flow path of the regulating hole, so as to achieve adaptive adjustment of the oil pumping flow rate and avoid insufficient or excessive oil due to different winding speeds.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: While existing wire rope strand twisting equipment can release and adjust the tension of the wire rope, it requires active operation. During the twisting process, the tension of the wire rope changes synchronously with the twisting speed and the unwinding speed, making it impossible for conventional tension adjustment mechanisms to automatically adjust in real time. This leads to an increased wire breakage rate during the wire twisting process. To solve this technical problem, this example discloses the following technical content, please refer to [link / reference]. Figures 1-5As shown; a constant tension twisting device for ultra-high strength steel wire rope strands includes a workbench 1, a support 2 fixedly installed above the workbench 1, and a first rotating disk 3 and a second rotating disk 4 rotatably mounted at both ends of the support 2, respectively. The first rotating disk 3 and the second rotating disk 4 are fixedly connected by a fixed connecting frame 5. A third rotating disk 11 is fixedly connected to the outer side of the second rotating disk 4. Holes for steel wires to pass through are evenly distributed on the first rotating disk 3, the second rotating disk 4, and the third rotating disk 11. The workbench 1 is equipped with a drive mechanism for the first rotating disk 3 and the second rotating disk 4. The drive assembly for rotating the disk 4 includes a wire feeding frame 9 evenly installed on the outer side of the first rotating disk 3, and a wire feeding wheel 10 rotatably mounted on the wire feeding frame 9. The wire feeding frame 9 is also equipped with a wire feeding resistance adjustment mechanism for adjusting the rotational resistance of the wire feeding wheel 10. The worktable 1 is also equipped with a collection trough 12 and a take-up wheel 15. Above the collection trough 12, an oil spraying assembly, a twisting die 13, and an oil scraper 14 are installed in sequence. The fixed connecting frame 5 is equipped with a tension adjustment assembly, and the tension adjustment assembly adjusts the wire tension by centrifugal force during the rotation of the first rotating disk 3 and the second rotating disk 4.

[0022] The drive assembly includes a motor 6 fixedly mounted on the workbench 1, and a gear 7 fixedly mounted on the output end of the motor 6. A gear ring 8 is fixedly mounted on the outer side of the first rotating disk 3. The gear 7 and the gear ring 8 are meshed together. The tension adjustment assembly includes a first slip ring 16 and a second slip ring 17 symmetrically slidably mounted on the fixed connecting frame 5. Springs are fixedly connected between the first rotating disk 3 and the first slip ring 16, and between the second rotating disk 4 and the second slip ring 17. Centrifugal blocks 19 are evenly hinged between the first slip ring 16 and the second slip ring 17 through hinge rods 18. During the rotation of the first slip ring 16 and the second slip ring 17, the centrifugal blocks 19 pull the first slip ring 16 and the second slip ring 17 closer together through the hinge rods 18 under centrifugal force. The tension adjustment assembly also includes an adjustment wheel group 20 evenly hinged through the hinge rods 18. The adjustment wheel group 20 is supported on the outer side of the steel wire. During the sliding of the first slip ring 16 and the second slip ring 17, the tension of the steel wire is adjusted through the adjustment wheel group 20.

[0023] During the twisting process, the control motor 6 drives the gear 7 to rotate, so that the gear 7 drives the first rotating disk 3 to rotate synchronously through meshing. As the first rotating disk 3 and the second rotating disk 4 rotate, the first slip ring 16 and the second slip ring 17 can rotate synchronously, so that the centrifugal block 19 connected between them moves under the action of centrifugal force. The centrifugal block 19 can pull the first slip ring 16 and the second slip ring 17 to slide elastically and move closer to the outside of the fixed connecting frame 5 through the hinge rod 18. At the same time, the adjusting wheel group 20 is adjusted through the hinge rod 18, so that the adjusting wheel group 20 adjusts and supports the steel wire, realizes the tension adaptation adjustment, avoids the excessive centrifugal tension of the steel wire at high speed, and prevents the steel wire from being pulled outward and the tension from rising.

[0024] The unwinding resistance adjustment mechanism includes an air reservoir 21 fixedly installed between the first rotating disk 3 and the first slip ring 16. A movable frame 22 is elastically slidably installed on the unwinding frame 9. An elastic bladder 23 is fixedly connected between the first rotating disk 3 and the movable frame 22. The air reservoir 21 and the elastic bladder 23 are connected by a pipe. During the contraction of the elastic bladder 23, it pulls the movable frame 22 away from the unwinding frame 9. An elastic pressure block 24 is fixedly installed on the movable frame 22. The elastic pressure block 24 is always in contact with the outer side of the unwinding wheel 10. At the same time, the sliding adjustment of the movable frame 22 realizes the adjustment of the unwinding resistance of the unwinding wheel 10.

[0025] As the first slip ring 16 slides, it can stretch the air storage bladder 21, allowing some of the gas in the elastic bladder 23 to enter the air storage bladder 21 through the pipe, causing the elastic bladder 23 to contract, thereby pulling the movable frame 22 away from the wire feeding frame 9. At this time, the compression of the elastic pressure block 24 decreases, reducing the pressure of the elastic pressure block 24 on the wire feeding wheel 10, thereby reducing the unwinding resistance of the wire feeding wheel 10 and further realizing the adaptive adjustment of the wire tension.

[0026] Example 2: The technical content disclosed in this example is a further improvement based on Example 1. Existing wire rope strand twisting equipment has a fixed lubricating oil spray volume, which makes it easy for the wires at different winding speeds to experience either insufficient oil or excessive oil, affecting subsequent scraping. To further solve this technical problem, this example discloses the following technical content: Figures 6-8 As shown; an oil pump is installed on the collection tank 12, and the oil pump is connected to a flow regulating component controlled by centrifugal force through the circulating oil pipe 28, and the flow regulating component is connected to the oil injection component through the oil pipe 34.

[0027] The fuel injection assembly includes a mounting bracket 25 fixedly installed on the collection tank 12, and a rotating ring 26 is rotatably mounted on the upper inner side of the mounting bracket 25. Fuel injection pipes 27 are evenly connected to the rotating ring 26, with the injection pipes 27 facing the steel wire. The flow regulation assembly includes a regulating pipe 29 fixedly installed on the outside of the bracket 2, and a connecting rod 30 is telescopically connected to the regulating pipe 29. A connecting plate 31 is fixedly installed at one end of the connecting rod 30 near the second slip ring 17. An annular guide groove is provided on the outer side of the second slip ring 17, and the connecting plate 31 and... The annular guide groove is slidably connected, and the second slip ring 17 drives the connecting rod 30 to move and adjust through the connecting plate 31. An adjustment hole 32 is opened in the cavity of the control tube 29, and a flow adjustment rod 33 is fixedly connected to one end of the connecting rod 30 located inside the control tube 29. The flow adjustment rod 33 has a frustum structure. At the same time, during the movement of the connecting rod 30, the flow adjustment rod 33 is driven to slide inside the adjustment hole 32 to adjust the flow path of the oil inside the control tube 29. The circulating oil pipe 28 and the oil delivery pipe 34 are respectively connected to the left and right sides of the adjustment hole 32.

[0028] During the twisting process, oil can be injected into the inner side of the rotating ring 26 through the oil pump, so that the oil can be sprayed onto the outer side of the steel wire through the oil spray pipe 27. When the third rotating disk 11 rotates, it will drive the rotating ring 26 to rotate. With the synchronous rotation of the rotating ring 26, the oil spraying effect can be further improved. At the same time, during the sliding of the second slip ring 17, the connecting plate 31 can drive the connecting rod 30 to move synchronously. Then, the connecting rod 30 can adjust the position of the flow regulating rod 33 in the regulating hole 32, thereby changing the oil flow path of the regulating hole 32 to achieve adaptive adjustment of the oil pumping flow rate, avoiding insufficient or excessive oil due to different winding speeds. The twisting die 13 can twist the oiled steel wire. Subsequently, the oil scraper 14 scrapes off the oil on the outer side of the twisted steel wire rope. Finally, the winding wheel 15 is used for uniform winding.
