Description

Technical Field

[0001] The present 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 the previous pure aluminum cable. Although the electrical conductivity of the cable is not improved, the bending performance, creep resistance and corrosion resistance are greatly improved. It can ensure that the cable maintains continuous and stable performance under long-term overload and overheating. The use of AA-8030 series aluminum alloy conductor can greatly improve the conductivity and high temperature resistance of the aluminum alloy cable, while solving the problems of pure aluminum conductor and creep. In the production process of aluminum alloy cable, stranding equipment is required;

[0003] However, during the use of the current aluminum alloy cable stranding equipment, due to the lack of a 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.

[0025] Compared with the prior art, the beneficial effects of the present application are: the structure of the present application is scientific and reasonable, and it is safe and convenient to use.

[0026] 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 metal wire pay-off process during the use of the aluminum alloy cable stranding equipment is optimized. By driving the mutual cooperation between the internal gear ring, the transmission side wheel and the shifting gear belt, the aluminum alloy belt roll can rotate at a uniform speed as the aluminum alloy cable moves during the pay-off process. In the pay-off process, the movable guide ring and the stranding drum frame cooperate with each other, so that the guide ring is always limited to the side of the stranding drum frame under the action of the aluminum alloy wire in the traction process, thereby further limiting 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 the 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 stranded wire strength of the aluminum alloy cable to decrease, thereby effectively improving the overall strength of the stranded wire of the aluminum alloy cable;

[0027] At the same time, by installing the cone box and the mutual cooperation between the transmission winding wheel and the limiting guide wheel on its top, the path of the aluminum alloy cable that has just been twisted and formed 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, thereby 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 mutual cooperation between the transposition pulley, the driving lower wheel and the transmission gear belt, the formed aluminum alloy cable is used to assist in paying out the untwisted aluminum alloy wire, effectively preventing the phenomenon that the overall quality of the aluminum alloy stranded wire is affected by internal defects caused by excessive load on the aluminum alloy monofilament, thereby further improving the overall product quality of the aluminum alloy cable.

[0028] At the same time, the sunken structural design of the round box is used to reduce the work required for replacing and transporting 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.

[0029] 2. The middle section limiting guide adjusting mechanism is provided, and the inspection guide process of the aluminum alloy single wire during transportation is optimized through the cooperation between the components in the middle section limiting guide adjusting mechanism. Through the cooperation between the limiting front frame top limiting guide roller and the pressing guide roller, the aluminum alloy single wire is preliminarily limited and guided, and the tension and the running speed of the aluminum alloy single wire are monitored during the guiding process, so that the tension imbalance and the broken wire condition during the running of the aluminum alloy single wire can be effectively prevented, the stability of the running of the aluminum alloy single wire is effectively improved, the defects during the production of the aluminum alloy cable strand can be effectively prevented, and the product quality of the aluminum alloy cable strand is improved.

[0030] Meanwhile, the running range of the aluminum alloy single wire can be limited and guided through the installation ring and the guide inner ring, so that the movement range of the aluminum alloy single wire is effectively limited, the included angle between the aluminum alloy single wire and the hole axis of the strand frame is effectively reduced, the friction between the strand frame and the aluminum alloy single wire is reduced, the continuous friction between the aluminum alloy single wire and the strand frame during the running of the aluminum alloy single wire is effectively prevented, the wear on the outer side of the aluminum alloy single wire is avoided, the scratch and wear on the edge of the hole of the strand frame are avoided, the service life of the strand frame is effectively improved, and the product quality of the aluminum alloy cable strand is improved.

[0031] In summary, the transportation process of the aluminum alloy single wire during the operation of the aluminum alloy cable strand equipment is optimized through the cooperation between the components in the synchronous rotation pay-off balancing mechanism and the middle section limiting guide adjusting mechanism. Through the optimization of the pay-off process of the aluminum alloy single wire, the additional torsional force on the aluminum alloy single wire is effectively removed, the phenomenon of the aluminum alloy single wire being off the roller or being twisted during the running of the aluminum alloy single wire is effectively prevented, the quality of the finished product of the aluminum alloy cable strand is ensured, the aluminum alloy single wire during the running is guided and monitored, the real-time detection of the tension and the running speed of the aluminum alloy single wire is realized, the broken wire or the wire jamming condition during the production of the aluminum alloy cable strand can be timely discovered, and the quality of the aluminum alloy cable strand product is effectively improved.

[0048] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0049] Example: Figures 1-11 As shown, the present invention provides a technical solution, an aluminum alloy cable stranding equipment, comprising a bottom support box 1, a stranding drum rack 2 is provided in the middle of the top surface of the bottom support box 1, and a stranding mold frame 3 is provided at a position on the top surface of the bottom support box 1 corresponding to one side of the stranding drum rack 2;

[0050] A synchronously rotating pay-off balancing mechanism 4 is provided on the top surface of the support box 1 at a position corresponding to one side of the stranding drum frame 2.

[0051] The synchronous rotation pay-off balancing mechanism 4 includes a mounting circular box 401, a mounting top ring 402, a driving inner gear ring 403, a mounting inner frame 404, an auxiliary motor 405, a driving central shaft 406, a circular discharge tray 407, a transposition pulley 408, a mounting cone box 409, a mounting top shaft 410, a transmission winding wheel 411, a mounting suspension 412, a limiting guide wheel 413, a transmission central shaft 414, a driving lower wheel 415, a transmission gear belt 416, a transmission side wheel 417, a driving inner wheel 418, a driving pulley 419, a rotating vertical shaft 420, a driven pulley 421, a transposition gear belt 422, a placement top plate 423, a central mounting shaft 424, a supporting rubber ring 425 and a guide ring 426;

[0054] The bottom end of the mounting top shaft 410 is fixedly connected with a transmission middle shaft 414 at the middle part position of the inner side of the mounting cone box 409, the outer side bottom end of the transmission middle shaft 414 is fixedly sleeved with a driving lower wheel 415 at the bottom position of the bottom support box 1, and the transmission gear belt 416 is collectively coated between the outer sides of the driving lower wheel 415 and the transposition pulley 408;

[0055] The bottom surface of the circular material placing disc 407 is rotatably connected with a transmission edge wheel 417 through a rotating shaft at a position corresponding to the inner part of the circular box 401. The bottom surface of the circular material placing disc 407 is rotatably connected with a driving inner wheel 418 through a rotating shaft at a position corresponding to one side of the transmission edge wheel 417. The top surface of the driving inner wheel 418 is fixedly connected with a driving belt wheel 419. The edge teeth of the transmission edge wheel 417 and the inner teeth of the driving inner tooth ring 403 are in meshing connection. The edge teeth of the transmission edge wheel 417 and the edge teeth of the driving inner wheel 418 are in meshing connection. Rotating vertical shafts 420 are rotatably connected with the bottom surface of the circular material placing disc 407 at positions corresponding to the outer side of the driving inner wheel 418. The outer bottom part of the rotating vertical shaft 420 is fixedly connected with a driven belt wheel 421. The driving belt wheel 419 and the driven belt wheel 421 are tightly covered with a transposed gear belt 422. The top end of the rotating vertical shaft 420 is fixedly connected with a placing top disc 423 at a position corresponding to the top part of the circular material placing disc 407. The top surface of the placing top disc 423 is fixedly connected with a center installation shaft 424 at a position corresponding to the middle part of the top surface.

The bottom surface of the placing top disc 423 is tightly and slidably connected with the guide ring of the top surface of the circular material placing disc 407. The center installation shaft 424 is a spline shaft, and the center installation shaft 424 and the aluminum alloy wire roller are in matching connection. Through the synchronous rotation of the internal components of the wire paying-off balance mechanism 4 and the matching connection between the components, the wire paying-off process of the aluminum alloy cable stranding equipment in use is optimized. Through the matching connection between the driving inner tooth ring 403, the transmission edge wheel 417 and the transposed gear belt 422, the aluminum alloy strip roll can rotate at a constant speed along with the movement of the aluminum alloy cable during the wire paying-off process. Through the matching connection between the movable guide ring 426 and the stranding disc frame 2 during the wire paying-off process, the guide ring 426 is always positioned towards one side of the stranding disc frame 2 under the action of the aluminum wire during the traction process. The wire paying-off path of the aluminum wire is further limited. Since there is a certain friction force between the connecting ring at the bottom of the guide ring 426 and the edge part of the placing top disc 423, when the tension of the wire just paid off from the aluminum alloy wire roll is loose, the placing top disc 423 can drive the guide ring 426 to deviate by a certain angle so that the front end of the aluminum wire just paid off can have sufficient tension. The aluminum wire is effectively prevented from deviating and twisting during the movement. Through the synchronous rotation of the placing top disc 423, the small amount of twisting force applied to the aluminum wire during the wire paying-off process of the aluminum alloy roll is removed. The small amount of twisting force remaining on the aluminum single wire is avoided to cause the stranding strength of the aluminum cable to decrease. The overall strength of the aluminum cable stranding is effectively improved.

[0056] Meanwhile, through the installation of the cone box 409 and the cooperation between the top transmission winding wheel 411 and the limiting guide wheel 413, the path of the just formed aluminum alloy cable is actively guided, and additional load is added to the running process of the aluminum alloy cable through the transmission winding wheel 411, so that the aluminum alloy after forming is effectively removed from the internal processing stress of the aluminum alloy cable under the action of bending and additional load, ensuring the stability of the internal structure of the aluminum alloy cable in the subsequent transportation process, further improving the effect of subsequent processing of the aluminum alloy cable, improving the overall structural strength of the aluminum alloy cable, and through the cooperation between the transposition pulley 408, the driving lower wheel 415 and the transmission gear belt 416, the formed aluminum alloy cable is used to assist the pay-off of the unwound aluminum alloy wire, effectively preventing the phenomenon that the internal defects of the aluminum alloy single wire due to excessive load affect the overall quality of the aluminum alloy strand, further improving the overall product quality of the aluminum alloy cable;

[0057] Meanwhile, through the sinking structure design of the circular box 401, the work of the replacement and transportation process of the aluminum alloy wire coil is less, thereby effectively improving the convenience of replacing the aluminum alloy wire coil, and through the spline shaft structure design of the center installation shaft 424, the fixing and installation limiting process of the aluminum alloy wire coil is more rapid and convenient, and the aluminum alloy wire coil end is assisted and supported by the supporting rubber ring 425, while ensuring that the placement top disc 423 can drive the aluminum alloy wire coil to rotate by friction, the bottom of the aluminum alloy wire coil is kept enough gap for transportation and lifting, effectively improving the usability of the aluminum cable stranding equipment;
