Description

Technical Field

[0001] This invention relates to the field of optical fiber take-up and lay-out equipment, and in particular to an automatic take-up and lay-out equipment for dual slip ring dual-core optical fibers. Background Technology

[0002] In existing technologies, fiber optic sensing, as an emerging sensing technology, is widely used in various fields such as military, defense, aerospace, industrial and mining enterprises, energy and environmental protection, industrial control, medical and health, computer measurement, home appliances, and civil engineering. Fiber optic communication has become the main transmission medium for modern communication. Optical fibers are typically stored by winding them around the outer circumference of a rotating roller. When needed, one end of the fiber is pulled to rotate the roller, gradually pulling the fiber out. After use, the roller is rotated in the opposite direction to retrieve the fiber. However, in practical production applications, manually winding and unwinding optical fibers is very time-consuming and labor-intensive. Existing rotating rollers cannot achieve automatic winding and unwinding operations, resulting in low work efficiency. Furthermore, manual operation can easily damage the optical fiber, causing economic losses. Additionally, they cannot wind and unwind dual-core optical fibers, limiting their application.

[0003] Chinese utility model patent application number 202222349346.5 discloses an automatic fiber optic take-up and release device in the field of fiber optic take-up and release equipment technology. It aims to solve the problem that existing fiber optic take-up and release devices have poor cable neatness and cannot automatically comb the fiber during take-up and release, thus easily damaging the working fiber. It includes a chassis, inside which are a drive mechanism, a transmission mechanism, a winding reel, and a cable laying mechanism. The drive mechanism drives the cable laying mechanism and the transmission mechanism to operate synchronously. The transmission mechanism is detachably connected to the winding reel and can drive the winding reel to rotate. The winding reel is used for take-up and release of fiber optics. The cable laying mechanism drives the fiber optics to reciprocate linearly during take-up and release by the winding reel to ensure uniform take-up and release. However, this type of automatic fiber optic take-up and release device in the field of fiber optic take-up and release equipment technology can only perform take-up and release operations on single-core fiber optics, and cannot perform take-up and release operations on dual-core fiber optics. It cannot transmit two sets of information signals simultaneously, and it uses a motor as a power source for take-up and release operations, which means that the fiber optics cannot be released under external traction, thus limiting its use.

[0026] An automatic take-up and lay-out device for dual-slip-ring dual-core optical fibers includes a base 1 mounted on a track. The device also includes a support mounting base serving as the main body of the take-up and lay-out device, a take-up and lay-out device for performing take-up and lay-out operations on the dual optical fibers, a take-up and lay-out system for guiding the take-up and lay-out of the dual-core optical fibers, and a reciprocating device for ensuring uniform fiber optic cabling.

Two sets of gearbox brackets 4 are arranged side-by-side at intervals on the upper end of the mounting base 2 and fixedly connected to it. The two sets of gearbox brackets 4 are located inside the two sets of support plates 3. The support mounting base, through the cooperation of the mounting base 2, support plate 3, and gearbox bracket 4, provides mounting support for the retraction device. Specifically, the mounting base 2 provides mounting support for the support plate 3 and gearbox bracket 4; the support plate 3, together with the mounting base 2, forms a support structure; and the gearbox bracket 4, under the action of the mounting base 2, provides mounting support for the retraction device.

The drive shaft 5 is located on the upper part of two sets of gearbox brackets 4, and its two ends are rotatably connected to the two sets of gearbox brackets 4 via bearings. The two ends of the drive shaft 5 protrude from the two sets of gearbox brackets 4 respectively. The cable storage cylinder 6 is located in the middle of the drive shaft 5 and is fixedly connected to the drive shaft 5 via spokes. There is one set of fiber optic limiting plates 7, which consists of two fiber optic limiting plates 7. The two fiber optic limiting plates 7 are symmetrically arranged at both ends of the cable storage cylinder 6 and fixedly connected to the cable storage cylinder 6. The diameter of the fiber optic limiting plates 7 is larger than the diameter of the cable storage cylinder 6. The cable storage cylinder 6 and the set of fiber optic limiting plates 7 are located between the two sets of gearbox brackets 4. The shaft 5 has a hollow internal structure, and the side of the drive shaft 5 has an optical fiber opening corresponding to the cable storage drum 6.

The coil spring assembly, through the cooperation of the power-accumulating coil springs 8 and the coil spring working covers 9, serves as the energy source for the wire take-up and unwinding equipment. In the storage section, the optical fiber is automatically wound and unwound. The energy storage spring 8 drives the drive shaft 5 to rotate through its own elasticity, thereby driving the storage drum 6 and the reciprocating device to work and automatically wound and unwound the optical fiber. The energy storage springs 8 are connected in sequence. The energy storage spring 8 furthest from the storage drum 6 is the constantly moving spring. When the spring assembly is working, it starts working first and is always in working state. The spring working cover 9 is used to protect the energy storage spring 8 and prevent foreign objects from jamming it.

[0030] The take-up and deployment system includes fiber optic slip rings 10, fiber optic protective covers 11, and fiber optic mounting shells 12. One set of fiber optic slip rings 10 is provided, consisting of two fiber optic slip rings 10, which are respectively located at both ends of the drive shaft 5 and fixedly connected to it. Two sets of fiber optic protective covers 11 are provided, respectively located on the outside of two sets of support plates 3 and fixedly connected to the corresponding support plates 3. Each support plate 3 has a cable-passing hole corresponding to the fiber optic protective cover 11. The fiber optic mounting shell 12 is located at one end of the base 1 and fixedly connected to it. The take-up and deployment system utilizes the fiber optic slip rings 10... The fiber optic protective cover 11 and the fiber optic mounting shell 12 work together to guide the two sets of single-core optical fibers, thereby realizing the take-up and take-up operation of dual-core optical fibers. This allows for the simultaneous transmission of two sets of information signals. The fiber optic slip ring 10 serves as the fiber mounting guide structure at both ends of the active shaft 5, guiding the two sets of single-core optical fibers to achieve the take-up and take-up operation of dual-core optical fibers. The fiber optic protective cover 11 forms the fiber optic protective structure on the outside of the support plate 3, protecting the two sets of single-core optical fibers.

[0031] The reciprocating device includes a reciprocating guide rod 13, a reciprocating guide rod 14, a guide wheel seat 15, and a guide wheel 16. The reciprocating guide rod 13 is located on the upper part of the base 1, and its two ends are rotatably connected to the base 1 via bearings. The reciprocating guide rod 14 is arranged side by side with the reciprocating guide rod 13 at intervals and is fixedly connected to the base 1 via a bracket. The guide wheel seat 15 is located in the middle of the reciprocating guide rod 13 and is slidably connected to the reciprocating guide rod 13 via a slider.

The guide wheel 16 is located at the lower part of the guide wheel seat 15 and is rotatably connected to the guide wheel seat 15. The side of the guide wheel 16 is provided with a guide groove corresponding to the optical fiber. The reciprocating device, through the cooperation of the reciprocating guide rod 13, the reciprocating guide rod 14, the guide wheel seat 15, and the guide wheel 16, operates during the wire take-up and unwinding process. The reciprocating motion ensures that the optical fibers are evenly distributed on the side of the cable storage drum 6, preventing knotting or tangling during cable winding and unwinding. The reciprocating guide rod 13 provides sliding support for the guide wheel seat 15 and, under the action of the coil spring assembly, drives the guide wheel seat 15 to slide horizontally. The reciprocating guide rod 14, in conjunction with the reciprocating guide rod 13, limits the guide wheel seat 15, allowing it to slide horizontally along the reciprocating guide rod 13. The guide wheel seat 15 provides mounting support for the guide wheel 16 and, under the action of the reciprocating guide rod 13, drives the guide wheel 16 to perform horizontal reciprocating motion. The guide wheel 16 guides the optical fibers through the guide groove on its side and, under the action of the guide wheel seat 15, performs horizontal reciprocating motion, thus ensuring that the optical fibers are evenly distributed on the side of the cable storage drum 6.

[0032] It also includes a guide wheel shaft 17, which is disposed on the lower inner side of the base 1 corresponding to the guide wheel 16 and its two ends are fixedly connected to the base 1. The guide wheel 16 passes through the guide wheel seat 15 and the guide wheel 16 and is slidably connected to the guide wheel seat 15 and the guide wheel 16.

[0033] It also includes a transmission assembly, which includes a driving synchronous pulley 18, a driven synchronous pulley 19, and a synchronous transmission belt 20. The driving synchronous pulley 18 is located at the end of the driving shaft 5 away from the energy storage disc spring 8 and is fixedly connected to the driving shaft 5. The driven synchronous pulley 19 is located at one end of the reciprocating guide rod 13 corresponding to the driving synchronous pulley 18 and is fixedly connected to the reciprocating guide rod 13. The synchronous transmission belt 20 is wound around the outside of the driving synchronous pulley 18 and the driven synchronous pulley 19 and is engaged with the driving synchronous pulley 18 and the driven synchronous pulley 19. The reciprocating guide rod 13 is... The transmission assembly is connected to the drive shaft 5. The transmission assembly works in conjunction with the drive synchronous pulley 18, the driven synchronous pulley 19 and the synchronous transmission belt 20 to serve as the transmission structure in the take-up and unwinding device, thereby connecting the take-up and unwinding device with the reciprocating device. The drive synchronous pulley 18 serves as the transmission structure on the drive shaft 5, the driven synchronous pulley 19 serves as the transmission mechanism on the reciprocating screw, and the synchronous transmission belt 20 connects the drive synchronous pulley 18 and the driven synchronous pulley 19, thereby connecting the take-up and unwinding device with the reciprocating device.

[0034] It also includes a coiling device, which includes a coiling ring 21, mounting magnets 22, and a cover 23. The coiling ring 21 is mounted on the inner side of the base 1 away from the fiber optic mounting shell 12 via a bracket. The side of the coiling ring 21 has a wire passage opening. At least two sets of mounting magnets 22 are provided, arranged on the outer side of the coiling ring 21. The cover 23 covers the outer side of the coiling ring 21, and the cover 23 has a connecting magnet corresponding to the mounting magnets 22. The cover 23 is magnetically connected to the mounting magnets 22 through the connecting magnets. The coiling device is connected via the coiling ring 21 and mounting magnets 22. The 22 and the cover 23 work together to form the coiling structure on the take-up and lay-out equipment. The coiling ring 21 serves as the main body of the coiling structure to collect and organize the excess fiber optic cable. The mounting magnet 22 serves as the connecting structure around the coiling ring 21. The cover 23 serves as the protective structure on the outside of the coiling ring 21, thereby protecting the coiling ring 21. When the take-up and lay-out equipment is in a ready-to-use state, the excess fiber optic cable can be coiled inside the coiling ring 21, and then the cover 23 can be fastened to the outside of the coiling ring 21 by the magnet structure to collect and organize the excess fiber optic cable for use.

[0035] It also includes an outer cover 24 and an optical fiber guide block 25. The outer cover 24 is disposed between two sets of support plates 3 and is fixedly connected to the support plates 3 by screws. The take-up and retraction device and the reciprocating device are both located inside the outer cover 24. The optical fiber guide block 25 is disposed inside the outer cover 24 on the side close to the optical fiber mounting shell 12 and is fixedly connected to the outer cover 24. The outer cover 24 is used as a protective structure outside the take-up and retraction device to protect the take-up and reciprocating device. The optical fiber guide block 25 is used as a guiding structure inside the outer cover 24 to guide the optical fiber.

[0036] In this design, four sets of energy-storing disc springs 8 and disc spring working covers 9 are provided. These four sets of energy-storing disc springs 8 are connected sequentially to serve as the energy storage component of the take-up and unwinding equipment. The four sets of energy-storing disc springs 8 rotate sequentially, not simultaneously, to ensure the continuous operation of the take-up and unwinding equipment. Specifically, the four sets of energy-storing disc springs 8 are connected end-to-end. When the disc spring assembly is working, the energy-storing disc spring 8 furthest from the wire storage drum 6 starts working first. After it releases, the next set of energy-storing disc springs 8 connected to it starts working and drives the energy-storing disc spring 8 furthest from the wire storage drum 6 to continue working. That is, the energy-storing disc spring 8 furthest from the wire storage drum 6 is a constantly moving disc spring, always in working condition. The energy-storing disc spring 8 drives the wire storage drum 6 to rotate via the drive shaft 5. After this set of energy-storing disc springs 8 releases, the next set of energy-storing disc springs 8 starts rotating and continues to drive the wire storage drum 6 to rotate via the drive shaft 5. This is the unwinding process of the take-up and unwinding equipment. The take-up process is the reverse of the unwinding process. A cross-sectional view of the energy-storing disc spring of this invention is shown below. Figure 5 As shown.

[0037] The working principle of the gearbox is as follows: it mainly consists of gears and shafts. The gear combination generates speed and torque, thereby changing the rotational speed and torque, and thus altering the output speed of the disc spring assembly. A cross-sectional view of the gearbox and disc spring assembly in this invention is shown below. Figure 6 As shown.

[0038] When the take-up and unwinding equipment is working, the coil spring assembly works, driving the drive shaft 5 to rotate through the gearbox. The drive shaft 5 drives the wire storage drum 6 to rotate, and at the same time drives the drive synchronous pulley 18 to rotate. The drive synchronous pulley 18 drives the driven synchronous pulley 19 to rotate through the synchronous transmission belt 20. The driven synchronous pulley 19 drives the reciprocating guide rod 13 to rotate. The reciprocating guide rod 13 drives the guide wheel 16 to reciprocate along the guide wheel shaft 17 through the guide wheel seat 15, thereby realizing the take-up and unwinding operation.

[0039] Working principle:

[0040] Two sets of single-core optical fibers are configured in an automatic take-up and release device via a take-up and release system. Under the action of slip rings 10, the fibers are guided and released. The fibers are wound around the storage drum 6 via the fiber opening on the drive shaft 5, forming a dual-core fiber structure that can transmit two sets of information signals simultaneously. The dual-core fibers pass through the wire groove on the side of the guide wheel 16 and exit the take-up and release device. The take-up and release device automatically performs take-up and release operations on the optical fibers through a coil spring assembly. The storage coil springs 8 in the coil spring assembly rotate in a superimposed sequence. The reciprocating device, through its reciprocating guide rod 13 structure, evenly distributes the optical fibers on the side of the storage drum 6. During operation, the optical fibers can be released under external traction. The cylinder 6 drives the drive shaft 5 to rotate, which in turn drives the energy storage spring 8 to rotate, thus storing energy in the energy storage spring 8. When the external force disappears, under the action of the spring assembly, the drive shaft 5 drives the storage cylinder 6 to rotate, thereby performing the fiber optic cable take-up operation. During the take-up process, the drive shaft 5 drives the reciprocating device through the transmission assembly. The reciprocating device drives the fiber optic cable to perform horizontal reciprocating motion through the reciprocating guide rod 13 structure, thereby evenly distributing the fiber optic cable on the side of the storage cylinder 6. When the take-up and take-up equipment is in a ready-to-use state, the excess fiber optic cable can be coiled inside the coiling ring 21, and then the cover 23 is fastened to the outside of the coiling ring 21 by a magnetic structure to collect and organize the excess fiber optic cable for use.

[0041] The beneficial effects of this invention are that it is equipped with a support mounting base and a take-up and unwinding device, which can perform take-up and unwinding operations on dual-core optical fibers, thereby realizing the simultaneous transmission of two sets of non-interfering information signals. Furthermore, it uses a coil spring assembly to realize the take-up and unwinding operation of the optical fiber, and the optical fiber can be unwound under external force. It has a wide range of applications. It is equipped with a reciprocating guide wire device, which can guide the sequential laying of dual-core optical fibers and avoid the optical fibers from becoming disordered or knotted during the take-up and unwinding process. It is equipped with a reciprocating guide rod, which can achieve uniform laying of dual-core optical fibers and ensure that the optical fibers are evenly arranged in the winding state.

[0042] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
