Description

Technical Field

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

[0002] Aluminum alloy cable is a new type of power cable invented by using AA8030 series aluminum alloy as conductor and adopting special pressing process and annealing treatment and other advanced technologies. It is a very mature high-tech environmentally friendly energy-saving green power cable. It not only has the ability to completely replace traditional copper core cables in terms of electrical performance and safety performance, but more importantly, its cost is 50% lower than that of traditional copper core cables while meeting the same electrical performance, which saves a lot of power facility investment costs for project investors and is in line with the development theme of building a conservation-oriented society in my country.

[0003] Current aluminum alloy cable preparation equipment usually uses water cooling and air cooling to cool the cables during the cable preparation process. Not only is the cooling efficiency low, the cooling medium is also easily adhered to the cable, and additional driving equipment is required, which increases the energy consumption of the equipment. In addition, since the cooling medium absorbs the heat dissipated by the cable and gradually heats up, its recycling effect is poor. During the cooling process, the cable is prone to uneven cooling in the front and back and uneven cooling in the circumferential direction, which makes the cable shape easily distorted. The cooling medium cannot be effectively recycled, and its direct contact with the cable not only causes a waste of resources, but is also prone to polluting the environment due to improper discharge.

[0021] A flexible aluminum alloy cable is manufactured by a flexible aluminum alloy cable manufacturing device.

[0022] Compared with the prior art, the invention has the following beneficial effects: the invention has a scientific and reasonable structure and is safe and convenient to use;

[0023] 1. A lossless shaping mechanism is provided. Through the cooperation of the winding roller and the spiral groove, the traction force of the cable can be transformed into a disturbance driving force, driving the refrigerant to circulate, effectively improving the energy utilization rate of the equipment and reducing the energy consumption of the equipment. With the guiding function of the square box, equal-position plate, heat dissipation pipe, drain valve, telescopic pipe, support, return pipe and air intake valve, the coil can be used to cool the cable without contact, which not only greatly improves the cooling rate of the cable, but also makes the cooling and forming effects of the front and rear sections of the cable consistent during the processing, so that each part of the cable is cooled evenly during the cooling process, effectively avoiding the distortion and inconsistency of the cable shape due to uneven cooling, so that the processing quality of the cable can be greatly improved. At the same time, it can also effectively reduce the impact of the cooling medium on the cable during the cooling process, while avoiding the adhesion of the cooling medium, realizing the recycling of the cooling medium, making the cooling and forming work of the cable more green and environmentally friendly.

[0024] 2. A labor-saving lever structure can be constructed by cooperating with the telescopic rod and the support rod. With the transmission and steering effect of the eccentric seat and the rocker, the driving force provided by the winding roller can be initially amplified and converted, which greatly improves the compatibility and adaptability of converting the cable tensioning force into the disturbance driving force. With the booster seat, plug plate, sleeve plate and connecting rod, the driving force provided by the winding roller can be secondary amplified using Pascal's law, which greatly reduces the energy consumption of the driving force supply, effectively improves the supply stability of the driving force, reduces the difficulty of obtaining the driving force, and makes the circulation flow of the refrigerant more stable and efficient. Through the cooperation of the convex cylinder, flow limiting cylinder, block, plug plate, top cylinder, push plate, push rod and connecting pipe, the refrigerant can be flow-limited and guided, which greatly improves the stability of the refrigerant gas-liquid conversion and makes the cooling work of the cable more durable and efficient.

[0025] 3. A positioning protection mechanism is set up. Through the cooperation of equal position rollers, reversing rollers and rotating sleeves, the cable can be pulled and guided. On the one hand, it can cooperate with threaded rods and threaded rings to limit the lateral position of the cable, and cooperate with lifting cylinders, guide rods, mounting seats, piston rings, transmission pipes and valves to synchronously correct the relative height of the cable. The travel path of the cable is accurately and synchronously corrected in multiple dimensions. The guiding effect of the insulation cylinder and ball bearings not only greatly reduces the difficulty of the correction work, but also reduces the friction resistance of the cable in the traction transmission process, making the limit adjustment of the cable more convenient, more flexible and more efficient, so that the equipment can be applied to cable processing of different sizes and specifications, making the non-contact circulation cooling work more reliable.

[0026] 4. Through the connecting rod and the strip, the cable can be prevented from offsetting and jamming during the traction transmission process, and the cable can be raised and lowered synchronously with the tensioning force, which greatly improves the compatibility of the cable limiting work and the tensioning force balancing work, making the cable processing more reliable. With the transmission adjustment function of the support tube, support plate and support rod, the guide hole and the air valve can be used to limit the initial tensioning force in the cable traction process, so that the cable is always in a tensioned state with appropriate tensioning force during the processing process, which greatly improves the traction transmission reliability of the cable, improves the stability of the tensioning force converted into a disturbance driving force, and effectively avoids the cable from being entangled and knotted. With the limiting function of the opening groove, mounting block, limit cavity, resistance plate and pull rod, the switch can be used to flexibly adjust the safe disturbance pressure and the safe production pressure, so that the equipment can be suitable for the processing needs of cables with different performances, expand the scope of application of the device, and improve the adaptability with the cooling work.

[0027] In summary, the preparation equipment for flexible aluminum alloy cables does not require additional electrical driving equipment, but converts the cable traction tension into a disturbance driving force, and doubly amplifies the disturbance force to perform non-contact refrigerant circulation cooling on the cable, which not only greatly improves the cooling rate and effect of the cable, but also effectively avoids the adhesion and impact of the cooling medium, and can quickly and accurately limit and adjust the cable's position and tension, greatly improving the processing stability of the cable.

[0057] In the cable traction and connection work, firstly, the cable is pulled from the previous process, so that the cable passes over the top of the equal position roller 301, then the cable passes through the bottom of the corresponding reversing roller 304, and passes over the top of the corresponding rotating sleeve 311, then the cable is passed through the heat insulation cylinder 316, and passes through the inner side of the coil 213, and then the cable is continued to be pulled, so that the cable passes over the top of the rotating sleeve 311 on the other side, passes through the bottom of the reversing roller 304 on the other side, and is wound around the winding roller 216 along the spiral groove 2161, and passes over the top of the winding roller 216, and finally, according to actual needs, the cable end is selected to be connected with the external winding mechanism or the next corresponding process, and the cable is in a tensioned state to complete the cable traction and connection work;

[0058] Then, the corresponding equipment parameters are set. First, according to the height of the cable inserted into the heat insulating cylinder 316, the hydraulic liquid is injected into the lifting cylinder 307 through the valve 315 and the guide rod 308, or the hydraulic liquid in the lifting cylinder 307 is extracted. Under the conduction effect of the threaded rod 310 and the transmission pipe 314, the hydraulic liquid at the bottom of the piston ring 313 in each lifting cylinder 307 will rise and fall synchronously, and the height of the rotating sleeves 311 on both sides will be synchronously regulated. Then, with the tension of the cable, the cable will rise and fall synchronously under the limiting effect of the rotating sleeve 311, and the relative height of the cable inserted into the heat insulating cylinder 316 will be adjusted so that this part of the cable is at the same height as the central axis of the heat insulating cylinder 316.

[0059] Then, the corresponding threaded ring 312 is rotated in sequence, and the position of the threaded ring 312 is adjusted under the drive of the external thread of the threaded rod 310 by using the screw drive principle, so that the corresponding rotating sleeve 311 slides along the threaded rod 310 accordingly, and then the cable is dragged by the rotating sleeve 311 to synchronously deviate along the axial direction of the threaded rod 310, so that the part of the cable that penetrates into the insulation tube 316 is aligned with the central axis of the insulation tube 316, and the cable is limited and corrected, so that the cable cannot contact the coil 213 during the subsequent traction process;

[0060] Then, air is filled into the support tube 318 through the guide hole 3181 through the air valve 3182, giving elastic support to the support plate 319, forcing the support plate 319 to move the support seat 212 up synchronously through the support rod 320, and then under the linkage action of the linkage rod 305 and the strip plate 306, the lifting tube 307 will rise synchronously, and then it will compress the hydraulic fluid at the bottom of the piston ring 313, forcing the guide rod 308 to move the mounting seat 309 up synchronously, and under the linkage action of the threaded rod 310, the rotating sleeve 311 will synchronously press the cable at the top, forcing the cable to be further tensioned, and then by controlling the air pressure inside the support tube 318, the initial tensioning force of the cable and the tensioning force during the processing process can be limited. Since the support 212 will drive the heat insulation tube 316 to move synchronously during this process, the position of the cable relative to the coil 213 will not change;

[0061] Then, air is filled into the limiting cavity 321 through the limiting valve 3211 to adjust the air pressure on the top of the resistance plate 322 so that the air pressure is greater than the tension threshold value of the air pressure inside the support tube 318 during the cable processing process. The air pressure is the safety threshold during the cable processing process. The pressure difference between the air pressure and the air pressure inside the support tube 318 is the maximum allowable fluctuation value of the air pressure. By limiting the difference, the cable stability and processing efficiency during the cable processing process can be adjusted in a biased manner.

[0062] During the cable processing, under the traction of the post-process, coupled with the aforementioned cable tension adjustment work and the limiting guiding function of the equal position roller 301, the cable will always remain in a tensioned state and synchronously press the reversing roller 304 and the rotating sleeve 311. Then, when the tension fluctuates during the cable traction process, the air pressure inside the limiting chamber 321 and the support tube 318 will fluctuate synchronously. When the air pressure is greater than the air pressure inside the support tube 318 and less than the air pressure inside the limiting chamber 321, it means that the tension on the cable is within the safe fluctuation range. The limiting chamber 321 will drop under the pressure to relieve the pressure fluctuation. When the air pressure is greater than the air pressure inside the limiting chamber 321, it means that the tension on the cable is about to exceed the threshold. The reversing roller 304 will overcome the air pressure on the resistance plate 322 under the pressure of the cable, drive the mounting block 303 to rise, and force the switch 324 to be triggered by the pressure. The switch 324 will cut off the external power supply and stop the processing to avoid cable damage.

[0063] Similarly, in the cable processing process, under the traction of the post-process, as the cable moves forward, the cable wound along the spiral groove 2161 will drive the winding roller 216 to rotate synchronously, and the winding roller 216 will drive the eccentric seat 217 to rotate synchronously, and then under the limiting action of the support rod 225, the telescopic rod 218 will swing back and forth around the support rod 225 accordingly, and drive the connecting rod 222 to move back and forth through the rocker 223, thereby forcing the plug plate 220 to move back and forth, and then under the hydraulic transmission, the two sleeve plates 221 will slide accordingly, and then under the communication action of the front conduit 2241 and the rear conduit 2242, the hydraulic fluid inside the booster seat 219 is forced to be pressed into the front cylinder 2031 and the rear cylinder 2032 in turn, and the two equal-position plates 205 are pressed back and forth, forcing the push plate 204 to move back and forth under the linkage action of the push rod 206;

[0064] In this process, the telescopic rod 218 and the support rod 225 constitute a primary amplification mechanism, which utilizes the length difference between the power rod 2181 and the resistance rod 2182 to initially amplify the driving force provided by the winding roller 216 through the lever principle, and the plug plate 220 and the sleeve plate 221 constitute a secondary amplification mechanism, which utilizes Pascal's law to further amplify the driving force provided by the winding roller 216, so that the push plate 204 can move back and forth more stably;

[0065] During the reciprocating movement of the push plate 204, the push plate 204 will squeeze the refrigerant in the gas-liquid equilibrium state inside the box 201, forcing the pressure on one side inside the box 201 to rise accordingly, breaking the gas-liquid equilibrium state of the refrigerant, and causing the refrigerant to reciprocate into the heat dissipation pipes 208 on both sides as the push plate 204 moves back and forth. Under the restriction of the refrigerant in the discharge valve 209 and the flow-limiting cylinder 207, the refrigerant in the box 201 can push the block 210 only when the pressure is greater than the critical pressure, and enter the support 212 through the telescopic tube 211, that is, the refrigerant will be liquefied inside the heat dissipation pipe 208, and the refrigerant entering the support 212 is in liquid state.

[0066] The liquid refrigerant will then enter the coil 213 and will quickly vaporize, absorbing the heat carried by the cable, so that the temperature inside the insulation tube 316 is always kept at a low temperature, and the cable is quickly cooled. During the reciprocating movement of the push plate 204, the pressure on the other side of the box 201 will drop accordingly, causing the vaporized refrigerant inside the coil 213 to enter the support 212 on the other side, and then pass through the two return pipes 214 in turn, and flow back into the box 201 through the corresponding air inlet valve 215. Then, as the push plate 204 moves back and forth, the refrigerant will circulate inside the above-mentioned flow path and convert into gas and liquid accordingly. During the cable processing process, the cable is cooled quickly, efficiently, with low energy consumption, and without pollution.

[0067] It should be noted here that in the above process, when the push plate 204 is displaced to one side of the front cylinder 2031, the refrigerant in the square box 201 will be pressed into the heat dissipation tube 208 on the outside of the convex cylinder 202 on the other side. As the refrigerant liquefies and releases heat, the internal air pressure of the convex cylinder 202 on the side of the rear cylinder 2032 rises. When the push plate 204 is displaced to the side of the rear cylinder 2032, the refrigerant in the square box 201 will be pressed into the heat dissipation tube 208 on the outside of the convex cylinder 202 on the side of the front cylinder 2031. As the refrigerant liquefies and releases heat, the internal air pressure of the convex cylinder 202 on the side of the front cylinder 2031 rises, and then with the driving force provided by the winding roller 216, the push plate 204 moves back and forth, that is, the driving force provided by the winding roller 216 is only a disturbing force to break the equilibrium state of the refrigerant, and the circulation flow of the refrigerant mainly relies on the thermal pressure conversion in its gas-liquid conversion process.
