Description
Technical Field
[0001] This invention belongs to the technical field of cable manufacturing, and specifically relates to a cable-making device for superconducting cables. Background Technology
[0002] Superconducting cables are high-efficiency power carriers that utilize superconducting materials to achieve zero-resistance power transmission at extremely low temperatures. The core manufacturing process is cable forming, which involves stranding multiple superconducting strands into a stable conductor using a specific structure. The stranding step is particularly critical, requiring the superconducting strands to be spirally wound in layers, in the same or opposite directions, using a stranding reel to form a compact strand.
[0003] The stranding reel has holes for the strands to pass through. The number of holes required on the stranding reel varies depending on the number of strands. During stranding, in order to ensure that each strand is subjected to uniform force, the spacing between any two adjacent holes on the stranding reel is equal. This means that the stranding reel needs to be replaced for stranding different numbers of strands, resulting in the defect of low applicability of stranding reels in cabling equipment. Summary of the Invention
[0004] This invention provides a cable-forming device for superconducting cables, aiming to solve the technical problem of low applicability of stranding reels in cable-forming devices.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a cable-forming device for superconducting cables, comprising a wire-laying system, a stranding system, and a wire-retrieving system arranged sequentially along a first direction, wherein the wire-laying system is used to release strands, and the wire-retrieving system is used to retrieve strands.

A telescopic member is fixed between the limiting block and the outer disk. The telescopic member extends and retracts along the moving direction of the limiting block.
[0016] In one possible implementation, the end face of the fixed arc that is not connected to the moving arc is recessed inward to form a rebound cavity. A pusher is installed in the rebound cavity. The pusher is used to push the single point that slides out from the feeding channel, so that the corresponding mounting hole fits around the outer periphery of the fixed arc.
[0017] In one possible implementation, the width of the feeding channel gradually decreases along the direction from the outer disk to the inner disk.

[0020] In one possible implementation, the inner wall of the storage slot has a hidden cavity, and a sealing plate is provided in the hidden cavity. The sealing plate is slidably connected to the moving arc, and the sealing plate moves around the axis of the moving arc. The sealing plate has a force-bearing surface on the side facing the compensation airbag. A first elastic member is fixed between the sealing plate and the moving arc. The first elastic member has a pre-tightening force that causes the sealing plate to extend out of the hidden cavity.
[0021] In one possible implementation, a negative pressure port is provided on the end face of the spacer arc facing away from the mounting base, and a suction chamber communicating with the spacer cavity is provided on the other end face of the spacer arc.

[0023] The side wall of the lever is provided with a side top groove, and a side top block is provided in the side top groove. The side top block is slidably connected to the lever. The moving direction of the side top block is perpendicular to the moving direction of the lever. A third elastic member is fixedly connected between the side top block and the lever.

[0024] A second base is fixed to the inner wall of the suction chamber, and a reverse rod is slidably connected to the second base along the axial direction of the fixed arc. The reverse rod abuts against the side top block.

Simultaneously, the threading rings can be removed individually; if a threading ring is damaged, it is not necessary to replace the entire stranding reel, reducing replacement costs. Furthermore, replacing the threading rings does not require removing the stranding reel, simplifying the replacement process. This invention improves the applicability and replacement convenience of the stranding reel and reduces replacement costs through the detachable threading rings. Attached Figure Description

[0039] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.
[0040] Please refer to the following: Figures 1 to 7 The cable-forming equipment for the superconducting cable of the present invention will be described. A cable-forming equipment for a superconducting cable includes a wire-laying system, a stranding system, and a wire-retrieving system arranged sequentially along a first direction. The wire-laying system is used to release strands, and the wire-retrieving system is used to retrieve strands. The wire-laying system and the wire-retrieving system are conventional prior art, and will not be described in detail in this application and are not shown in the figures. The stranding system includes a first base 10, a stranding disc 20, and a driving component. The first base 10 is fixed to the ground. The stranding disc 20 is rotatably connected to the first base 10. The stranding disc 20 includes an inner disc 201, an outer disc 202 spaced around the outer periphery of the inner disc 201, a support roller fixed between the inner disc 201 and the outer disc 202, and a plurality of threading rings 203 detachably connected to the support roller. A threading hole 2011 is provided through the center of the inner disc 201. The driving component is connected to the stranding disc 20 and is used to drive the stranding disc 20 to rotate around a horizontal axis. The driving component is a servo motor. The driving component is connected to the stranding disc 20 via belt drive, chain drive, or gear drive, which will not be described in detail in this application.
[0041] The superconducting cable cabling equipment provided in this embodiment determines the number of threading rings 203 to be installed based on the number of strands, so that the number of threading rings 203 always remains consistent with the number of strands; at the same time, the installation positions of the threading rings 203 are arranged according to the number of threading rings 203, so that when any number of threading rings 203 are arranged, adjacent threading rings 203 maintain an equal distance.
[0042] Compared with existing technologies, by setting a detachable threading ring 203 between the inner disc 201 and the outer disc 202, the number and distribution of threading points on the same stranding disc 20 can be dynamically adjusted. When the number of strands changes, only the number of threading rings 203 needs to be increased or decreased and the threading rings rearranged to ensure that adjacent points are always equidistant, thus ensuring uniform tension of each superconducting strand during stranding. Simultaneously, the threading ring 203 can be disassembled individually; if one threading ring 203 is damaged, it is not necessary to replace the entire stranding disc 20, reducing replacement costs. Furthermore, replacing the threading ring 203 does not require removing the stranding disc 20, simplifying the replacement process. This invention improves the applicability and replacement convenience of the stranding disc 20 and reduces replacement costs through the detachable threading ring 203.
[0043] In some embodiments, see Figure 2 and Figure 6 The support roller includes a fixed arc 204, a movable arc 205 slidably connected to the fixed arc 204, and an opening and closing power component connected to the movable arc 205. The end face of the fixed arc 204 is recessed inward to form a sliding cavity 2041 for receiving the movable arc 205. The opening and closing power component is used to drive the movable arc 205 to move along the axis of the fixed arc 204.
[0044] The stranding system also includes multiple mountings and multiple spacer assemblies 40; the mounting base 30 corresponds one-to-one with the threading ring 203, the mounting base 30 and the threading ring 203 are detachably connected, the mounting base 30 has a mounting hole 301 for inserting the support roller, and spacer cavities 302 are provided on both sides of the mounting base 30; the spacer assembly 40 corresponds one-to-one with the mounting base 30, the spacer assembly 40 includes two spacer arcs 401 that slide one-to-one in the spacer cavity 302 and a spacer power member 402 that is driven to the spacer arcs 401, the spacer power member 402 is used to drive the spacer arcs 401 to move along the axis of the fixed arc 204.
[0045] Optionally, the opening and closing power component is an air pump. The opening and closing power component injects gas into the slide cavity 2041, and the gas in the slide cavity 2041 gradually increases, thereby pushing the moving arc 205 out of the slide cavity 2041 until it abuts against the fixed arc 204, thus forming a closed loop of the support roller; the opening and closing power component sucks away the gas in the slide cavity 2041, and the gas in the slide cavity 2041 gradually decreases, thereby drawing the moving arc 205 into the slide cavity 2041, thus forming an open loop of the support roller.
[0046] Optionally, the opening and closing power component is an arc-shaped slide rail. The inner wall of the slide cavity 2041 has a first arc-shaped groove for placing the opening and closing power component. The slide seat of the opening and closing power component is fixedly connected to the moving arc 205. When the opening and closing power component is activated in the forward direction, it pushes the moving arc 205 out of the slide cavity 2041, thereby forming a closed loop of the support roller. When the opening and closing power component is activated in the reverse direction, it pulls the moving arc 205 into the slide cavity 2041, thereby forming an open loop of the support roller.
[0047] Optionally, the spacer power component 402 is an air pump. The spacer power component 402 injects gas into the spacer cavity 302, and the gas in the spacer cavity 302 gradually increases, thereby pushing the spacer arc 401 out of the spacer cavity 302. By controlling the amount of gas injected into the spacer cavity 302, the length of the spacer arc 401 is controlled, thereby adapting to different spacings. The spacer power component 402 sucks away the gas in the spacer cavity 302, and the gas in the spacer cavity 302 gradually decreases, thereby sucking the spacer arc 401 into the spacer cavity 302.
[0048] Optionally, the spacer power component 402 is an arc-shaped slide rail, and the inner wall of the spacer cavity 302 is provided with a second arc-shaped groove for placing the spacer power component 402. The slide of the spacer power component 402 is fixedly connected to the spacer arc 401. When the spacer power component 402 is activated in the forward direction, it pushes the spacer arc 401 out of the spacer cavity 302. The length of the spacer arc 401 extending is controlled by controlling the moving distance of the slide of the spacer power component 402. When the spacer power component 402 is activated in the reverse direction, it retracts the spacer arc 401 into the slide cavity 2041.
[0049] Optionally, the threading ring 203 is fixedly connected to the mounting base 30.
[0050] Optionally, the threading ring 203 is detachably connected to the mounting base 30. The mounting base 30 has a slot, and the threading ring 203 is fixedly connected to a locking block that fits into the slot, with the locking block and slot having an interference fit. The threading ring 203 and the mounting base 30 are designed for a plug-in connection, facilitating the removal of the threading ring 203 and allowing for the replacement of threading rings 203 with different hole sizes, thereby adapting to different strand diameters.
[0051] After determining the number of threading rings 203 based on the number of strands, the opening and closing power component is activated to retract the moving arc 205 into the sliding cavity 2041. Then, the mounting seat 30 is moved so that the mounting hole 301 is aligned with the fixed arc 204, thereby fitting the mounting seat 30 onto the fixed arc 204. After the mounting seat 30 is fitted, the opening and closing power component is activated to extend the moving arc 205 so that the support roller forms a closed loop. Then, the interval power component 402 is activated to extend the interval arc 401, thereby evenly arranging the mounting seats 30, and thus evenly arranging the threading holes 2011.
[0052] In some embodiments, see Figure 5The mounting base 30 and the corresponding threading ring 203 form a single point; the highest point of the inner wall of the outer plate 202 is recessed inward to form a feeding channel 2021. A storage cavity 2022 is formed on the inner wall of the feeding channel 2021. The angle formed between the extending direction of the storage cavity 2022 and the extending direction of the feeding channel 2021 is an obtuse angle. Multiple limiting grooves 2023 are formed on the inner wall of the storage cavity 2022. These limiting grooves 2023 are spaced apart along the extending direction of the storage cavity 2022. The side of the positioning groove 2023 opposite to the material feeding channel 2021 is used to place a single point. The limiting groove 2023 is provided with a limiting block 2024. The limiting block 2024 is slidably connected to the outer disk 202. The moving direction of the limiting block 2024 is perpendicular to the extending direction of the storage cavity 2022. A telescopic component 2025 is fixedly connected between the limiting block 2024 and the outer disk 202. The telescopic component 2025 extends and retracts along the moving direction of the limiting block 2024. The telescopic component 2025 is a telescopic oil cylinder or hydraulic cylinder.
[0053] It should be noted that the number of limit blocks 2024 to be placed in the limit slots 2023 is determined according to the number of strands. The limit block 2024 is the first one from the side closest to the feeding channel 2021. Then, the limit blocks 2024 are counted sequentially from the side closest to the feeding channel 2021. The limit blocks 2024 can be placed in the limit slots 2023 one by one, or they can be placed in the limit slots 2023 together.
[0054] After the moving arc 205 is retracted into the sliding cavity 2041, the telescopic component 2025 is activated and retracted to retract the limiting block 2024 into the limiting groove 2023, so that the single point slides into the unloading channel 2021 until the single point slides out of the unloading channel 2021. Then, the threading ring 203 abuts against the outer wall of the inner plate 201, the mounting hole 301 is aligned with the fixed arc 204, and then the mounting seat 30 is pushed so that the mounting hole 301 is fitted onto the fixed arc 204.
[0055] In some embodiments, see Figure 6 The end face of the fixed arc 204 that is not connected to the moving arc 205 is recessed inward to form a rebound cavity 2042. A pusher 2043 is installed in the rebound cavity 2042. The pusher 2043 is used to push the single point that slides out from the feeding channel 2021 so that the corresponding mounting hole 301 is fitted onto the outer periphery of the fixed arc 204.
[0056] Optionally, the pusher 2043 is an air pump. The pusher 2043 is activated to blow out gas, thereby pushing the mounting base 30 to move, so that the mounting hole 301 fits onto the fixed arc 204.
[0057] Optionally, the pusher 2043 can be a telescopic cylinder or a hydraulic cylinder. The pusher 2043 extends, thereby pushing the mounting base 30 to move, so that the mounting hole 301 fits onto the fixed arc 204.
[0058] In some embodiments, see Figure 5 The width of the feeding channel 2021 gradually decreases along the direction from the outer plate 202 to the inner plate 201.
[0059] The entrance of the feeding channel 2021 is set to be relatively wide, which makes it easy for a single point to enter the feeding channel 2021. The width of the feeding channel 2021 gradually decreases from the entrance to the exit, so that the single point slides out of the feeding channel 2021 and falls exactly into the open ring of the support ring.
[0060] In some embodiments, see Figure 6 The outer wall of the moving arc 205 is provided with a compensating airbag 206, and the moving arc 205 is provided with a first pneumatic component that communicates with the compensating airbag 206. The first pneumatic component is an air pump.
[0061] After the mounting bases 30 are arranged, if the outer periphery of the moving arc 205 is covered by the mounting bases 30, the first pneumatic component is activated to inflate the compensating airbag 206, causing the compensating airbag 206 to expand, thereby fixing the mounting bases 30 and the moving arc 205.
[0062] In some embodiments, see Figure 6 The outer wall of the moving arc 205 is provided with multiple storage slots 2061, which are spaced apart around the axis of the moving arc 205. The compensation airbag 206 is located in the storage slot 2061.
[0063] During the movement of the moving arc 205, the compensating airbag 206 is always placed in the receiving groove 2061, thereby reducing the wear on the compensating airbag 206 and extending its service life. After the first pneumatic component is activated, the compensating airbag 206 expands and overflows from the receiving groove 2061, thereby pressing the moving arc 205 and the mounting base 30 together.
[0064] In some embodiments, see Figure 7 The inner wall of the storage slot 2061 is provided with a hidden cavity 2062, and a sealing plate 2063 is provided in the hidden cavity 2062. The sealing plate 2063 is slidably connected to the moving arc 205. The sealing plate 2063 moves around the axis of the moving arc 205. The sealing plate 2063 has a force-bearing surface on the side facing the compensation airbag 206. A first elastic member 2064 is fixedly connected between the sealing plate 2063 and the moving arc 205. The first elastic member 2064 has a pre-tightening force to make the sealing plate 2063 extend out of the hidden cavity 2062. The first elastic member 2064 is a spring or a spring rod.
[0065] During the movement of the moving arc 205, the compensating airbag 206 is retracted into the receiving groove 2061. At this time, the sealing plate 2063 seals the receiving groove 2061, isolating the compensating airbag 206 from the outside world, thereby avoiding wear on the compensating airbag 206 and further extending the service life of the compensating airbag 206. After the first pneumatic component is activated, the compensating airbag 206 expands and compresses the force-bearing surface. At this time, the first elastic component 2064 is compressed, causing the sealing plate 2063 to retract into the hidden cavity 2062, thereby pushing the compensating airbag 206 out of the receiving groove 2061. Thus, the compensating airbag 206 presses the moving arc 205 against the mounting base 30.
[0066] In some embodiments, see Figure 3 and Figure 4 A negative pressure port 4011 is provided on the end face of the interval arc 401 away from the mounting base 30. A suction chamber 4012 communicating with the interval cavity 302 is provided on the other end face of the interval arc 401. A piston 4013 is provided in the negative pressure port 4011. The piston 4013 is slidably connected to the interval arc 401 along the axial direction of the fixed arc 204.
[0067] A lever 4014 is slidably connected to the interval arc 401 along the axial direction of the fixed arc 204. One end of the lever 4014 extends into the suction chamber 4012, and the other end of the lever 4014 extends into the negative pressure port 4011 and is fixedly connected to the piston 4013. A second elastic member 4015 is fixedly connected between the lever 4014 and the interval arc 401. The second elastic member 4015 has a preload force that causes the piston 4013 to move inward toward the negative pressure port 4011. The second elastic member 4015 is a spring.
[0068] The side wall of the lever 4014 has a side top groove 40141, and a side top block 40142 is provided in the side top groove 40141. The side top block 40142 is slidably connected to the lever 4014. The moving direction of the side top block 40142 is perpendicular to the moving direction of the lever 4014. A third elastic member 40143 is fixedly connected between the side top block 40142 and the lever 4014. The third elastic member 40143 has a pre-tightening force that causes the side top block 40142 to extend out of the side top groove 40141. The third elastic member 40143 is a spring.
[0069] A second base 4016 is fixedly connected to the inner wall of the suction chamber 4012. A reverse rod 4017 is slidably connected inside the second base 4016 along the axial direction of the fixed arc 204. The reverse rod 4017 abuts against the top block.
[0070] When the spacer power component 402 is an air pump, the spacer pneumatic component is activated to blow air into the spacer cavity 302. At this time, the gas enters the spacer cavity 302 and the suction cavity 4012. After the gas enters the suction cavity 4012, the elastic force of the third elastic component 40143 prevents the gas from pushing the reverse rod 4017 to move. As a result, the gas first pushes the spacer arc 401 out of the spacer cavity 302. After the two spacer arcs 401 come into contact, the gas continues to enter the suction chamber 4012. The gas gradually accumulates in the suction chamber 4012 until it overcomes the elastic force of the third elastic member 40143, causing the reverse rod 4017 to draw the side top block 40142 into the side top groove 40141. As a result, the second elastic member 4015 releases its elastic force, driving the pull rod 4014 to move towards the suction chamber 4012, causing the piston 4013 to move towards the inside of the negative pressure port 4011. This causes the two spacer arcs 401 to attract each other, enhancing the connection stability between the spacer arcs 401.
[0071] In some embodiments, see Figure 3 The suction chamber 4012 has a plug 4018 at its port. The plug 4018 is rotatably connected to the spacer arc 401. The rotation axis of the plug 4018 is perpendicular to the axis of the spacer arc 401. A fourth elastic element is installed on the rotatable connection between the plug 4018 and the spacer arc 401. The fourth elastic element is a torsion spring. The fourth elastic element has a pre-tightening force that causes the plug 4018 to seal the suction chamber 4012.
[0072] When the spacer power component 402 is an air pump, the spacer pneumatic component is activated to blow air into the spacer cavity 302. Due to the fourth elastic component, the gas cannot enter the suction cavity 4012. When the two spacer arcs 401 are in contact, the gas accumulates in the spacer cavity 302 until it overcomes the elasticity of the fourth elastic component, allowing the gas to continuously enter the suction cavity 4012 until the gas overcomes the elasticity of the third elastic component 40143. Therefore, when the spacer arcs 401 are not in contact, the gas will not enter the suction cavity 4012, and the gas is only used for the movement of the spacer arcs 401.
[0073] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
