Description

Technical Field

[0001] This invention relates to a cable armor forming device and its process, belonging to the field of cable processing technology. Background Technology

[0002] Armored cables are cables with a steel strip (or copper strip) wrapped around the outer layer of the cable's insulation. This effectively improves the cable's shielding performance, reduces damage during compression, and decreases the frequency of short circuits. Additionally, the steel strip protects the cable from damage by rodents, insects, and birds, thus protecting power transmission in the field.

[0003] Most existing cable armoring equipment uses double-layer armoring, wrapping the cable with steel or copper strips. Traditionally, the reels are fixed to the outside of the shaft, and the armoring material is wound onto the reels before the reels are mounted on the armoring machine for feeding. However, reels with armoring material are quite heavy, and if the base lacks protective measures or is not strong enough, they can easily fall and injure workers. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a cable armor forming device and process, which solves the problem that exposed cable reels are prone to collisions and safety accidents in the prior art.

[0005] The technical problem to be solved by the present invention is achieved by the following technical solution: a cable armor forming device, comprising a base fixed to the ground and a guide disc disposed on the base; The disc is rotatably disposed within the inner ring of the guide disc and is capable of rotating along the circumferential direction of the guide disc; A gear turntable is disposed inside the guide disc and is provided with a drive source. The gear turntable is used to drive the belt disc to rotate. The cable reel is provided in two parts, and a cable guide is provided between the two reels. The cable guide includes a guide ring concentrically arranged with the guide disc. The guide ring has a through hole in the middle and a buffer ring is provided. The cable passes through the through hole in the middle of the guide ring during armoring. A connecting shell for connecting the reels is connected to the guide ring.

[0006] By adopting the above technical solution, the safety performance of the entire device can be greatly improved. In this application, by simultaneously placing two reels inside the guide disc, it completely differs from the conventional mode of traditional armoring machines. The reels rotate along the circumference of the guide disc. During rotation, the guide disc's protective function isolates them from the external environment, reducing operator contact and improving safety. Simultaneously, by using the guide disc as a motion guide ring for the reels, and cooperating with the gear turntable drive within the guide disc, the rotation of the reels becomes more stable, reducing the amplitude of offset jitter during rotation. This improves the quality of cable armoring and prevents gaps from forming in the cable due to excessive bending during the armoring process.

[0007] The present invention is further configured such that: the tape reel includes a main reel, which is spliced ​​together from two circular plates, and a core for storing metal tape is rotatably disposed between the two circular plates; a through hole is opened in the middle of the main reel and a snap-fit ​​connector is slidably disposed on the through hole; a plurality of inner wall snap-fit ​​strips are disposed on the inner wall of the through hole of the main reel; and the snap-fit ​​connector is snapped into the inner ring of the connecting housing.

[0008] By adopting the above technical solution, the entire pulley is double-fixed through the connecting shell and the clamping joint, which enables the pulley to rotate relatively stably during rotation. At the same time, the detachable pulley makes it easier to quickly replace the pulley during subsequent armoring processes, which can effectively improve work efficiency.

[0009] The present invention is further configured such that: a fixed guide shaft is provided on the reel, the two ends of the fixed guide shaft are respectively rotatably disposed on the circular plate, a circular guide rail is provided on the outer surface of the circular plate, and a movable guide component is slidably disposed on the circular guide rail, the movable guide component being used to adjust the angle at which the metal strip extends outward.

[0010] By adopting the above technical solution, the extension point of the metal strip on the reel can be adjusted by the guiding component, thereby controlling the armoring angle between the metal strip and the cable, and controlling the winding spacing of the metal strip during the armoring process. This avoids excessive repeated armoring when the metal strip is winding around a cable with a small diameter, reducing material consumption and saving processing costs.

[0011] The present invention is further configured such that: the guiding component includes two movable plates slidably disposed on the circular guide rail, an angle adjustment plate is disposed between the two movable plates, and a movable guide shaft is disposed on the angle adjustment plate, the movable guide shaft being used to guide the metal strip and adjust its extension angle.

[0012] By adopting the above technical solution, the position of the cable when it extends can be further adjusted by the angle adjustment plate, and the angle of the movable guide shaft itself can be adjusted to better adapt to cables of different diameters, thereby effectively improving the armoring efficiency and armoring quality of the cable.

[0013] The invention is further configured such that: the movable plate includes a snap-fit ​​part that snaps into the circular guide rail and a mounting part for mounting the angle adjustment plate; the mounting part has a through groove; the end of the angle adjustment plate is slidably snapped into the through groove; a screw is rotatably disposed in the through groove; a push nut is sleeved on the screw; the push nut slides along the screw after the screw rotates and pushes the angle adjustment plate to slide.

[0014] By adopting the above technical solution, the tilt angle of the angle adjustment plate is adjusted by using a screw, so that the engagement points of the angle adjustment plate on the two movable plates are different, thereby forming a guide support structure with a tilt angle. This allows the metal strip to be offset at a certain angle after passing through the angle adjustment plate, so that it can fit more closely with the cable after it extends out, and maintain a relatively stable output during the subsequent armoring process.

[0015] The present invention is further configured such that there are two movable guide shafts, and the metal strip is clamped between the two movable guide shafts.

[0016] By adopting the above technical solution, the metal strip can be better guided, preventing the metal strip from detaching from the movable guide shaft.

[0017] The invention is further configured such that the metal strip can be a copper strip, a steel strip, or an aluminum strip.

[0018] By adopting the above technical solution and replacing the materials used for cable armoring, users can make reasonable material selections based on the different armoring requirements of different cables, thus expanding the applicability.

[0019] The present invention is further configured such that: the driving source includes a transmission gear meshing with the gear turntable; the guide disc has an assembly port for mounting the transmission gear; and the transmission gear is equipped with a drive motor for driving its rotation.

[0020] By adopting the above technical solution, the gear turntable is driven by the meshing of two gears, which in turn drives the rotation of two belt discs. Throughout the process, the transmission accuracy can remain constant and the stability is high.

[0021] The present invention is further configured such that a reinforcing rod connected to the gear turntable is also connected to the guide ring.

[0022] By adopting the above technical solution, the center of gravity of the two reels can be shifted to the middle of the entire rotation axis, thereby making them more stable during rotation. This effectively avoids the situation where the reels break off due to insufficient stability after the rotation speed is too high, increases the maximum rotation speed of the reels, and can accelerate the armoring efficiency of the cable.

[0023] This application also relates to a cable armor forming process, which specifically includes the following steps: Step 1: Connect a guide rope to the end of the unarmored cable. Pass the guide rope through the through hole in the middle of the guide ring and extend it into the rubber coating assembly. After passing through the rubber coating assembly, fix the end to the winding equipment. Control the winding equipment to pull the guide rope to move, thereby driving the cable forward. Step 2: Fix the two reels to the inner ring of the gear turntable using the cable guide, and pull the metal strip out from the reel core, pass it around the fixed guide shaft, and then pass it out between the two movable guide shafts; Step 3: Secure the metal strip that has been pulled out to the cable with tape or clamps, and adjust the position of the guide components on the two reels relative to the fixed guide shaft so that the metal strip pulled out rotates in the same direction relative to the cable when the two reels rotate. Step 4: By controlling the rotation of the screw, adjust the tilt angle of the two angle adjustment plates to make the tilt angle of the metal strips on the two reels consistent. Step 5: Control the gear turntable to rotate via the drive source, which in turn drives the two belt reels to rotate, so that the two metal strips are wound onto the cable in sequence. At the same time, control the external winding equipment to pull the cable to move forward and complete the armoring process. After the armored cable is coated by the coating assembly, it is cooled down and finally wound up uniformly by the external winding assembly.

[0024] By adopting the above technical solution, the cable is guided by a guide rope through the armoring and coating processes in sequence. The gear turntable synchronously drives the two tape reels to rotate, so that the metal tape is wrapped around the cable surface at the same inclination angle. Then, the armored cable is coated, cooled and wound up, thereby realizing the continuous, efficient and uniform automated bimetallic tape armoring operation of the cable.

[0025] The beneficial effects of this invention are: By using a guide disc, in conjunction with a gear turntable to fix and drive the pulleys to rotate, the rotation paths of the two pulleys are contained within the guide disc. This results in better stability of the entire armor forming device. Unlike traditional armoring machines, the guide disc effectively prevents contact between the pulleys and the operator during the armoring process due to operator error, thanks to the protection of the guide disc. By using a gear turntable to control the pulley rotation, the main force point during pulley rotation in traditional armoring machines is transformed from single-point, single-line force on the main shaft to multi-point planar force, thus achieving more stable support for the pulleys.

[0026] The cable guide allows for quick installation and fixation of the reel, improving work efficiency. The reel and cable guide are detachable, enabling rapid reel replacement without the need for reloading, significantly reducing overall processing time and increasing efficiency.

[0029] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this invention, the invention will be further described below in conjunction with specific illustrations.

[0030] like Figure 1 and Figure 2 As shown, a cable armor forming device includes a base 1 fixed to the ground and a guide disc 2 set on the base 1. The guide disc 2 is generally annular with a through hole in the middle. A gear disc 4 is rotatably installed on the inner ring of the guide disc 2. Two tape reels 3 are installed on the inner ring of the gear disc 4. The metal strip is wound onto the tape reels 3. The entire tape reel 3 can rotate synchronously with the gear disc 4. Its rotation path is a circular rotation along the inner circumference of the guide disc 2. During the armoring process of the cable 7, the rotation of the gear disc 4 is controlled to drive the two tape reels 3 to rotate, thereby realizing the armoring of the cable 7.

[0031] In a specific embodiment, the gear turntable 4 is provided with a drive source 5 to drive its rotation. The drive source 5 includes a drive motor 501 fixed on the guide disk 2 and a transmission gear 502 connected to the output shaft of the drive motor 501. An assembly port 201 is provided on the guide disk 2, and the part of the transmission gear 502 that meshes with the gear turntable 4 is located in the assembly port 201.

[0032] In the above embodiment, by arranging the two reels 3 completely inside the guide disc 2, unlike the traditional armoring machine structure where the reels 3 are arranged outside the rotating shaft, the reels 3 are rotated along the circumference of the guide disc 2 by the gear turntable 4, thereby realizing the armoring process of the cable 7. Throughout the process, since the rotation path of the reels 3 is entirely within the inner circle of the guide disc 2, it can effectively reduce operator accidental contact and improve the safety performance of the armoring machine. At the same time, the setting of the guide disc 2 can not only fix and guide the two reels 3, but also stabilize the center of gravity of the reels 3 during rotation, reducing the vibration amplitude, thus making the rotation of the reels 3 more stable. On the other hand, since the reels 3 are driven by the gear turntable 4 when rotating, their force point changes from the axial force of the traditional center of gravity axis to the planar force, so there is no need to worry about the torque change during the rotation of the reels 3 causing deformation of the rotating shaft.

[0033] Furthermore, an end cap is provided on the guide disk 2, and the gear turntable 4 is fixed inside the entire guide disk 2 by the end cap. Figure 2 As shown, a circular receiving groove for accommodating the gear turntable 4 is provided on the surface of the guide disc 2. At the same time, a circular snap-fit ​​slide rail 401 is provided on the gear turntable 4. After the gear turntable 4 is fixedly and rotatably installed in the circular receiving groove through the circular snap-fit ​​slide rail 401, the end cover is fixed to the guide disc 2 by bolts, so that the gear turntable 4 is clamped in the circular receiving groove and can rotate relative to the circular receiving groove.

[0034] like Figure 2 and Figure 3 As shown, a cable guide 6 is provided between the two reels 3. The cable guide 6 is used to clamp and fix the reels 3. The cable guide 6 includes a guide ring 601 concentrically arranged with the guide disc 2. The entire guide ring 601 has a rectangular cross-section with a through hole in the middle. During armoring, the cable 7 passes through the through hole in the middle. A buffer ring (not shown) can be detachably installed in the middle through hole of the guide ring 601. When the cable 7 undergoes slight bending during armoring, it can be buffered by the buffer ring to reduce stress concentration. In a specific embodiment, the buffer ring can be made of materials with cushioning effect such as sponge or rubber.

[0035] Furthermore, a connecting housing 602 for connecting the reel 3 is connected to the guide ring 601. The connecting housing 602 is cylindrical with a mating hole in the middle. At least two snap-fit ​​strips 604 are equidistantly arranged on the inner surface of the mating hole. The entire guide ring 601 and the connecting housing 602 are slidably connected. By controlling the sliding of the connecting housing 602 relative to the guide ring 601, the outward extension distance of the connecting housing 602 can be adjusted.

[0036] like Figure 4 As shown, the reel 3 comprises a main reel 301, a core (not shown), a metal strip, and a guide assembly. The main reel 301 is composed of two circular plates 302 joined together, with the joining point located at the center of the two plates. A through hole is formed at the center of the main reel 301. A core for holding the metal strip is rotatably mounted between the two plates. A transition through hole is formed in the center of the main reel 301, and a locking connector 303 is slidably disposed in the transition through hole. At least two locking grooves are formed on the outer surface of the locking connector 303, and several inner wall locking strips 304 are provided on the inner wall of the transition through hole. When the reel 3 is stored, the locking connector 303 can slide into the entire transition through hole, thereby reducing the overall space occupied by the reel 3.

[0037] In this embodiment, six snap-fit ​​strips 604 of the same length are circumferentially and equidistantly arranged on the inner ring surface of the connecting housing 602. Six snap-fit ​​grooves of the same length as the snap-fit ​​strips 604 are circumferentially and equidistantly arranged on the outer surface of the snap-fit ​​connector 303 on the main disk 301. Four cylindrical connecting blocks 402 are circumferentially and equidistantly arranged on the gear turntable 4. Threaded holes are opened at the ends of the cylindrical connecting blocks 402. The outer surfaces of two opposing cylindrical connecting blocks 402 are provided with external threads and clamping blocks 9 are sleeved on the outside. The end of the clamping block 9 is rotatably provided with a push ring 10 that is threadedly connected to the outer surface of the cylindrical connecting block 402. By rotating the push ring 10, the entire clamping block 9 can be pushed to slide towards the center of the gear turntable 4.

[0038] The guide ring 601 is also connected to a reinforcing rod 603 that is connected to the gear turntable 4. This allows the center of gravity of the two pulleys 3 to be biased towards the middle of the entire rotation axis when they rotate, thereby making them more stable during rotation. This effectively prevents the pulleys 3 from flying off due to insufficient stability when the speed is too high, increases the maximum speed of the pulleys 3, and can speed up the armoring efficiency of the cable 7.

[0039] Specifically, a threaded connecting rod 606 is provided inside the reinforcing rod 603, and a knob ring 605 is rotatably installed at the end of the reinforcing rod 603. The knob ring 605 and the threaded connecting rod 606 are threadedly connected. By rotating the knob ring 605, the threaded connecting rod 606 can be pushed out of the reinforcing rod 603 and then rotated to connect with the cylindrical connecting block 402.

[0040] During the installation of the pulley 3, firstly, push the connector on the pulley 3 into the transition through hole in the middle of the pulley 3, lifting the pulley 3 between the cylindrical connecting block 402 and the connecting housing 602. After aligning the center of the pulley 3 with the central axis of the cylindrical connecting block 402, push the ring 10 by turning the knob to push the clamping block 9 outward, so that the pushing block slides into the through hole in the middle of the pulley 3, pushing out the connector in the through hole. After the connector is pushed out, it is locked into the connecting housing 602 on the other side of the pulley 3. By inserting the connector into the inner ring of the connecting housing 602, the locking strip 604 of the inner ring of the connecting housing 602 is aligned with the locking groove, thus achieving the limiting and fixing of the pulley 3. After fixing, one end face of the pulley 3 is radially locked by the connector inserted into the connecting housing 602 to prevent it from rotating, while the other end face is axially limited by the clamping force applied by the clamping block 9 to prevent it from moving axially.

[0041] In the above embodiment, at least six lever insertion holes are arranged equidistantly around the circumference of the push ring 10. By setting the lever insertion holes, when the push ring 10 is rotated later, the lever can be inserted into the lever insertion hole to assist in turning the knob, thereby improving installation efficiency and ease of installation.

[0042] The above-described structure allows users to quickly install and replace the pulley 3, improving processing efficiency. The pulley 3 is clamped and fixed by the clamping block 9 and the connecting shell. When the pulley 3 rotates synchronously with the gear turntable 4, the centrifugal force it generates applies pressure to the clamping block 9, thus pushing the push ring 10 connected to the clamping block 9. The push ring 10 itself is fixed to the cylindrical connecting block 402 via a threaded connection. Therefore, after being pushed, the threaded fit between the push ring 10 and the cylindrical connecting block 402 becomes tighter, greatly reducing the possibility of loosening between the push ring 10 and the cylindrical connecting block 402, and improving the stability of the pulley 3 during rotation.

[0043] like Figure 5 and Figure 6 As shown, a fixed guide shaft 305 is also provided on the reel 3. The two ends of the fixed guide shaft 305 are respectively rotatably mounted on the circular plate 302. A circular guide rail 306 is also provided on the outer surface of the circular plate 302. A movable guide component 307 is slidably mounted on the circular guide rail 306. The movable guide component 307 is used to adjust the angle at which the metal strip extends outward.

[0044] The guiding assembly includes two movable plates 3071 that are slidably mounted on a circular guide rail 306. An angle adjustment plate 3072 is provided between the two movable plates 3071. A movable guide shaft 3073 is provided on the angle adjustment plate 3072. The movable guide shaft 3073 is used to guide the metal strip and adjust its extension angle.

[0045] Specifically, the movable plate 3071 includes a snap-fit ​​part 3074 that snaps into the circular guide rail 306 and a mounting part 3075 for mounting the angle adjustment plate 3072. A groove is provided on the inner surface of the snap-fit ​​part 3074 to snap into the circular guide rail 306. A through groove is provided on the mounting part 3075. The end of the angle adjustment plate 3072 is slidably snapped into the through groove. At the same time, a screw 3076 is rotatably provided in the through groove. A push nut 3077 is sleeved on the screw 3076. The push nut 3077 can slide along the screw 3076 after the screw 3076 rotates and push the angle adjustment plate 3072 to slide.

[0046] In this embodiment, the push nut 3077 of the screw 3076 is slidably engaged in the through groove and sleeved on the screw 3076, threadedly connected to the screw 3076. When the user adjusts the rotation of the screw 3076, since the push nut 3077 can only slide up and down in the through groove, the nut cannot rotate synchronously after the screw 3076 rotates due to the engagement of the through groove. This causes the push nut 3077 to slide only downwards or upwards, thereby controlling the connection point of the entire angle adjustment plate 3072 on the through groove. By adjusting the connection position of the angle adjustment plate 3072 on the two movable plates 3071 through the screws 3076 on both sides of the knob, the tilt angle of the angle adjustment plate 3072 can be controlled. This changes the angle at which the metal strip extends outwards after passing through the movable guide shaft 3073, allowing for better fit with the target cable 7 requiring armor, improving armor quality, and preventing damage or convergence of the metal strip due to excessive twisting.

[0047] The upper end of the screw 3076 extends through a slot and is provided with a knob head at the end. In one embodiment, the knob head is hexagonal, and the user can control the rotation of the knob head by using an external hexagonal wrench.

[0048] like Figure 6As shown in the above embodiment, the number of angle adjustment plates 3072 in a single movable guide assembly 307 is two, and each of the two angle adjustment plates 3072 has a long groove in the middle. Two movable guide shafts connect the two angle adjustment plates 3072 to each other, and the two angle adjustment plates 3072 are slidably engaged with the screws 3076 in the through groove through the long grooves on their upper parts. Furthermore, the number of movable guide shafts 3073 is two, and a metal strip is clamped between the two movable guide shafts 3073. The metal strip can be copper strip, steel strip, or aluminum strip. By changing different materials to armor the cable 7, users can make reasonable material selection according to the different armoring requirements of different cables 7, thus broadening the applicability.

[0049] Based on the above embodiment, a pressure sensor is installed on the side of the push nut 3077 that abuts against the angle adjustment plate 3072. The pressure sensor can monitor the pressure applied by the metal strip to the push nut 3077 in real time during the armoring process. The internal tension of the metal strip during armoring can be determined by the pressure, so as to prevent the metal strip from breaking due to excessive tension or the armor between the metal strip and the cable 7 from being not tight enough due to insufficient tension.

[0050] Specifically, the pressure sensor adopts a circular plate structure with a through hole in the middle. The pressure sensor is fixed to the end face of the push nut 3077 with glue or tape. At the same time, the pressure sensor is connected to an alarm. The alarm is triggered according to the monitoring value on the pressure sensor. An alarm will be generated when the monitored pressure is too low or too high, so as to remind the staff to adjust the transmission speed of the cable 7 and the rotation speed of the pulley 3.

[0051] By combining pressure sensors and alarms, the entire armoring process of cable 7 can be monitored in real time, which can free up labor to a certain extent and provide early warning of accidents.

[0052] like Figure 1 As shown, the two sides of the base 1 are the inlet and outlet ends of the cable 7, respectively. A rubber-coating assembly 8 is provided at the outlet end of the cable 7. This assembly allows for the rapid wrapping of an insulating rubber layer around the armored cable 7, further tightening the fit between the cable 7 and the metal strip and preventing the metal strip from loosening. In this embodiment, the rubber-coating assembly 8 employs a commonly used rubber-coating process in the prior art; its specific structure will not be described in detail here.

[0053] Based on the above embodiments, this application also relates to a cable armor forming process, specifically including the following steps: Step 1: Connect a guide rope to the end of the unarmored cable 7. Pass the guide rope through the through hole in the guide ring 601 and extend it into the coating assembly 8. After passing through the coating assembly 8, fix the end to the winding equipment. Control the winding equipment to pull the guide rope, thereby moving the cable 7 forward. The guide rope effectively increases the armor length of the cable 7's front end, eliminating the need to cut the front end after armoring and avoiding material waste.

[0054] Step 2: Fix the two tape reels 3 to the inner ring of the gear turntable 4 through the cable guide 6, and pull the metal tape out from the core of the reel, pass it around the fixed guide shaft 305 and then pass it out between the two movable guide shafts 3073. Step 3: Fix the metal strip that has been pulled out to the cable 7 with tape or clamps, and adjust the position of the guide components on the two reels 3 relative to the fixed guide shaft 305 so that the metal strip pulled out when the two reels 3 rotate rotates in the same direction relative to the cable 7. Step 4: By controlling the rotation of the screw 3076, adjust the tilt angle of the two angle adjustment plates 3072 so that the tilt angle of the metal strips on the two pulleys 3 is consistent. Step 5: The drive source 5 controls the rotation of the gear turntable 4, which in turn drives the two tape reels 3 to rotate, causing the two metal tapes to be wound sequentially onto the cable 7. Simultaneously, the external winding device pulls the cable 7 forward, completing the armoring process. After armoring, the cable 7 is coated with adhesive by the coating assembly 8 and then cooled. Finally, it is wound up uniformly by the external winding assembly. During the cooling process, the armored and coated cable 7 is guided through a cold water tank filled with flowing cold water, which rapidly cools the cable 7.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of the invention, all of which fall within the scope of protection claimed by the present invention.
