Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy cables, in particular to an aluminum alloy cable stranding device and a cable thereof. Background Art

[0002] Aluminum alloy power cable is a new type of power cable with AA8030 series aluminum alloy as conductor, using special roll-formed wire stranding production process and annealing treatment and other advanced technologies. The alloy power cable makes up for the shortcomings of pure aluminum cables in the past. Although the electrical conductivity of the cable is not improved, the bending performance, creep resistance and corrosion resistance are greatly improved, which can ensure that the cable maintains continuous performance stability when overloaded and overheated for a long time. The use of AA-8030 series aluminum alloy conductors can greatly improve the conductivity and high temperature resistance of aluminum alloy cables, and solve the problems of pure aluminum conductors and creep. In the production process of aluminum alloy cables, stranding equipment is required; However, during the use of the current aluminum alloy cable stranding equipment, due to the lack of corresponding auxiliary wire-releasing structure, the metal wire on the aluminum alloy monofilament roller will have a certain torsional force when it is separated from the top of the roller, causing the aluminum alloy wire to bend and deform during the subsequent transportation. In addition, when multiple bundles of aluminum alloy wires are subsequently stranded, the torsional deformation of the aluminum alloy monofilament will reduce the overall winding strength of the aluminum alloy cable, thereby reducing the overall quality of the aluminum alloy cable.

[0014] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use: 1. A synchronous rotating pay-off balancing mechanism is set up. Through the mutual cooperation between the internal components of the synchronous rotating pay-off balancing mechanism, the wire pay-off process of the aluminum alloy cable stranding equipment is optimized. Through the mutual cooperation between the driving inner gear ring, the transmission side wheel and the transposition gear belt, the aluminum alloy belt roll can rotate at a uniform speed with the movement of the aluminum alloy cable during the pay-off process. In the pay-off process, through the mutual cooperation between the movable guide ring and the stranding drum frame, the limit notch of the guide ring is always facing the side of the stranding drum frame under the action of the aluminum alloy wire in the traction process, so as to further limit the pay-off path of the aluminum alloy wire. Since there is a certain friction between the connecting ring at the bottom of the guide ring and the edge of the placing top plate, when the tension of the metal wire just released from the aluminum alloy wire coil is relatively loose, the placing top plate can drive the guide ring to deviate by a certain angle so that the front end of the aluminum alloy wire just released can have sufficient tension, effectively preventing the aluminum alloy wire from deviating and twisting during the process of traveling, and removing a small amount of torsional force applied to the aluminum alloy wire during the aluminum alloy winding and unwinding process through the synchronous rotation of the placing top plate, avoiding the small amount of torsional force remaining on the aluminum alloy monofilament causing the strength of the aluminum alloy cable strands to decrease, thereby effectively improving the overall strength of the aluminum alloy cable strands; At the same time, by installing the cone box and the cooperation between the transmission winding wheel on its top and the limiting guide wheel, the path of the aluminum alloy cable that has just been twisted is actively guided, and the transmission winding wheel is used to add additional load to the travel process of the aluminum alloy cable, so that the aluminum alloy that has just been formed can effectively remove part of the processing stress inside the aluminum alloy cable strand under the action of bending and additional load, ensuring the stability of the internal structure of the aluminum alloy cable during subsequent transportation, further improving the effect of subsequent processing of the aluminum alloy cable, and improving the overall structural strength of the aluminum alloy cable. At the same time, through the cooperation between the transposition pulley, the driving lower wheel and the transmission gear belt, the formed aluminum alloy cable is used to assist in laying out the untwisted aluminum alloy wire, effectively preventing the phenomenon that the overall quality of the aluminum alloy strand is affected by defects caused by excessive load on the aluminum alloy monofilament, and further improving the overall product quality of the aluminum alloy cable; At the same time, the sunken structural design of the round box is used to reduce the work required in the replacement and transportation process of the aluminum alloy wire coil, thereby effectively improving the convenience of replacing the aluminum alloy wire coil. At the same time, the spline shaft structural design of the central mounting shaft makes the fixed installation and limiting process of the aluminum alloy wire coil faster and more convenient, and the supporting rubber ring is used to provide auxiliary support to the end of the aluminum alloy wire coil. While ensuring that the top plate can drive the aluminum alloy wire coil to rotate through friction, the bottom of the aluminum alloy wire coil maintains sufficient clearance for transportation and lifting, effectively improving the usability of the aluminum alloy cable stranding equipment.

[0015] 2. A middle-section limit guide adjustment mechanism is set up. Through the mutual cooperation between the components inside the middle-section limit guide adjustment mechanism, the inspection and guidance process during the transportation of the aluminum alloy monofilament is optimized. Through the mutual cooperation between the limit guide roller and the clamping guide roller on the top of the limit front frame, the initial limit guide of the aluminum alloy monofilament is realized, and the tension and travel speed of the aluminum alloy monofilament are monitored during the guidance process, which effectively prevents the tension imbalance and wire breakage during the travel of the aluminum alloy monofilament. It can effectively improve the stability of the aluminum alloy monofilament operation, and effectively prevent defects in the production process of aluminum alloy cable strands from being discovered in time, thereby improving the overall product quality of aluminum alloy cable strands; At the same time, the installation ring and the guide inner ring can be used to limit and guide the travel range of the aluminum alloy monofilament, thereby effectively limiting the movement range of the aluminum alloy monofilament, and then effectively reducing the angle between the aluminum alloy monofilament and the axis of the channel on the stranded wire drum frame, thereby reducing the friction between the stranded wire drum frame and the aluminum alloy monofilament, and effectively preventing the aluminum alloy monofilament from continuous friction with the stranded wire drum frame during travel, resulting in wear on the outside of the aluminum alloy monofilament, and avoiding scratches and wear on the edge of the stranded wire drum frame channel, thereby effectively increasing the service life of the stranded wire drum frame and improving the product quality of the aluminum alloy cable strands.

[0016] To sum up, through the mutual cooperation between the components inside the synchronously rotating pay-off balancing mechanism and the middle-section limit guiding and adjusting mechanism, the transportation process of the aluminum alloy monofilament during the operation of the aluminum alloy cable stranding equipment is optimized. By optimizing the pay-off process of the aluminum alloy monofilament, the extra torsional force on the aluminum alloy monofilament is effectively removed, and the aluminum alloy monofilament is effectively prevented from being de-rolled or twisted during the movement, thereby ensuring the quality of the finished product of the aluminum alloy cable strand. At the same time, the moving aluminum alloy monofilament is guided and monitored, thereby realizing real-time detection of the tension and travel speed of the aluminum alloy monofilament, ensuring that the broken wire or stuck wire in the production process of the aluminum alloy cable stranding can be discovered in time, effectively improving the quality of the aluminum alloy cable stranding products.

[0021] According to the above technical solution, an aluminum alloy cable is a cable produced by an aluminum alloy cable stranding equipment.

[0022] Working principle and use process of the present invention: In the process of winding aluminum alloy cables using aluminum alloy cable stranding equipment, the present invention needs to first install and place the aluminum alloy wire coil in a suitable position, and twist and pull the aluminum alloy metal wire through the stranding drum frame 2, and then strand the aluminum alloy metal wire through the stranding die frame 3, and pull the formed aluminum alloy cable through the traction device at the tail end of the aluminum alloy cable production line to complete the production of the aluminum alloy cable; When installing the aluminum alloy wire coil, the aluminum alloy wire coil is clamped and limited by the central installation shaft 424, and the end face of the aluminum alloy wire coil is auxiliary supported by the support rubber ring 425, so that a gap is left between the rear end face of the aluminum alloy wire coil after installation and the placement top plate 423, so as to facilitate the installation and transportation of the aluminum alloy wire coil, and then the aluminum alloy wire released from the aluminum alloy wire coil is limited and guided by the guide ring 426, and at the same time, it is installed to both sides of the installation cone box 409 through the installation suspension 412, and then the aluminum alloy cable extending from the end of the stranded wire mold frame 3 is guided by the limiting guide wheel 413, and the aluminum alloy cable is wound around the transmission winding wheel 411 during the movement, so that the aluminum alloy cable and the transmission winding wheel 411 are more closely fitted, and then the movement of the aluminum alloy cable drives the transmission winding wheel 411 to rotate; During the rotation of the transmission winding wheel 411, the installation top shaft 410 and the transmission middle shaft 414 are synchronously driven to rotate, and during the rotation of the transmission middle shaft 414, the driving lower wheel 415 is synchronously driven to rotate, and during the rotation of the driving lower wheel 415, the transposition pulley 408 is synchronously driven to rotate synchronously through the transposition gear belt 422, and then the driving middle shaft 406 is driven to rotate through the transposition pulley 408, and during the rotation of the driving middle shaft 406, the driving inner gear ring 403 can be synchronously driven to rotate synchronously, and the rotation of the driving inner gear ring 403 can synchronously drive the driving side wheel 417 to rotate, and then the driving inner wheel 418 is driven to rotate through the transmission side wheel 417, and While the inner driving wheel 418 is rotating, the driving pulley 419 is synchronously driven to rotate. During the rotation of the driving pulley 419, the multiple driven pulleys 421 are driven to rotate synchronously through the transposition gear belt 422. During the rotation of the driven pulley 421, the multiple placement top plates 423 are driven to rotate synchronously through the rotating vertical shaft 420. During the rotation of the placement top plate 423, the aluminum alloy wire coil is driven to rotate and unwind, and the torsional force on the aluminum alloy wire is eliminated through the active rotation of the aluminum alloy wire coil. At the same time, when the driving force of the transmission gear belt 416 is insufficient, the auxiliary motor 405 can be started to drive the driving middle shaft 406 to rotate, so as to ensure the normal rotation of the driving inner gear ring 403. When it is necessary to guide the aluminum alloy monofilament in the process of traveling, the limiting guide roller 504 is evenly installed to the front end of the stranding drum frame 2 through the mutual cooperation between the limiting front frame 501 and the installing front frame 502, and then the aluminum alloy monofilament is guided and limited through the mutual cooperation between the limiting guide roller 504 and the pressing guide roller 511. At the same time, through the retractable characteristics of the connecting rubber rod 506, the lifting installation block 507 can drive the connecting flat rod 508 and the components thereon to be lifted and lowered synchronously, so that the pressing guide roller 511 can be closely fitted with the traveling aluminum alloy monofilament. When the tension at the bottom of the corresponding pressing guide roller 511 changes, the corresponding lifting slide frame 510 and the pressing guide roller 511 are driven to rise by the reverse force of the aluminum alloy monofilament, thereby changing the value of the pressure sensor 509 to realize real-time detection of the tension of the corresponding aluminum alloy monofilament. At the same time, the rotation speed of the pressing guide roller 511 is monitored by the laser rotation speed sensor 512, so that the real-time monitoring of the traveling speed of the aluminum alloy monofilament can be realized. In the process of the aluminum alloy monofilament moving from the top of the limiting front frame 501 to the stranding drum frame 2, it is necessary to further shrink the distribution range of the aluminum alloy monofilament in motion, install the mounting ring 514 to the side of the stranding drum frame 2 by guiding the rear frame 513, and flexibly fix the guide inner ring 516 to the inside of the mounting ring 514 by the limiting spring 515, and limit and shrink the outer ring aluminum alloy monofilament in the process of movement by the guiding inclined roller 521 to prevent the aluminum alloy monofilament from having a large central axial deviation angle with the hole on the stranding drum frame 2 during the process of movement, resulting in serious scratching between the inner wall of the hole of the stranding drum frame 2 and the outer side of the aluminum alloy monofilament, and at the same time, the repulsive force between the fixed magnetic block 518 and the sliding magnetic block 520 drives the sliding inner frame 519 to slide along the inner wall of the mounting guide groove 517, and then when the tension on the aluminum alloy monofilament changes, the tension on the aluminum alloy monofilament is kept stable by the action of the guiding inclined roller 521, so as to optimize the traveling and transportation process of the aluminum alloy monofilament.
