Description

Technical Field

[0001] This utility model relates to the field of optical cable stranding technology, and in particular to an optical fiber cable steel wire stranding device. Background Technology

[0002] Optical fiber cables are communication cable assemblies formed from optical fibers (optical transmission carriers) through processing. They can transmit optical signals. In the production process of optical fiber cables, in order to improve their mechanical strength and prevent them from being easily damaged by external forces during installation or use, one or two steel wires are usually twisted into the optical cable. These steel wires are also called reinforcing steel wires, which can improve the mechanical strength of the optical cable.

[0003] However, when stranding steel wires onto optical fibers, the machine needs to be stopped every time a roll of steel wire is used up. The used roll of steel wire must be removed before the next roll of steel wire is installed. Then, the end of the steel wire on the roll of steel wire must be connected to the end of the optical fiber before the stranding work can continue. There are many roll-changing steps in between, which is time-consuming and reduces the stranding efficiency.

[0004] Therefore, it is necessary to provide a new fiber optic cable wire stranding device to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a fiber optic cable wire stranding device that allows for quick replacement of the wire roll and improves stranding efficiency to a certain extent.

By setting a bearing shaft inside the installation port and two first concave frames loaded with steel wire rolls on the bearing shaft, the old and new steel wire rolls can be quickly replaced by rotating the bearing shaft when a steel wire roll is used up.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please refer to the following: Figures 1-9The fiber optic cable steel wire stranding device includes: a base 1, on which a support threading plate 2, a bearing plate 4, and a first rodless cylinder 19 are fixedly installed. The support threading plate 2 is located between the bearing plate 4 and the first rodless cylinder 19. The support threading plate 2 has a wire-jointing hole 3. A connecting disc 5 is rotatably mounted on the bearing plate 4. The connecting disc 5 has an optical fiber hole 6 and two mounting openings 7. The optical fiber hole 6 is located between the two mounting openings 7 and is coaxial with the wire-jointing hole 3, allowing for smooth insertion of optical fibers and steel wires. A bearing shaft 8 is rotatably mounted in each of the two mounting openings 7. Two connecting arms 9 are fixedly mounted on each of the two bearing shafts 8. First concave frames 10 are detachably mounted on the ends of all four connecting arms 9. Each frame 10 is equipped with a wire roll 11. A first servo motor is fixedly installed on one side of the outer wall of each of the four first concave frames 10. The output shafts of the four first servo motors are fixedly connected to one end of each of the four wire rolls 11. The wire can be released at a uniform speed by running the first servo motor. A gear ring is fixedly installed on the side of the connecting disc 5 away from the supporting threading plate 2. A drive motor is fixedly installed on the top of the base 1. A gear is fixedly installed on its output shaft. The gear meshes with the gear ring. By using the meshing of the two, the connecting disc 5 can be rotated, thereby enabling the two wires and the optical fiber to be twisted together. In addition, in order to provide a correct movement guide for the wire, two guide rings 18 are fixedly installed on the side of the connecting disc 5 near the supporting threading plate 2.

[0026] In the above method, in order to fix the bearing shaft 8 in the designated position, a locking groove 12 is provided on the top inner wall and bottom inner wall of the two mounting ports 7. A support frame 13 is fixedly installed on each of the two bearing shafts 8. A threaded rod 14 is threadedly installed on the side of the two support frames 13 that is far apart from each other. A locking rod 15 is rotatably installed on the side of the two threaded rods 14 that is far apart from each other. The side of the two locking rods 15 that is far apart from each other extends into the corresponding locking groove 12. Furthermore, a guide folding rod is slidably installed on each of the two support frames 13. One end of the two guide folding rods is fixedly connected to the two locking rods 15 respectively to form a limiting effect. In addition, the locking groove 12 is relatively shallow, and the locking rod 15 can be removed by rotating the threaded rod 14 a few times, thereby improving the ease of operation.

[0027] In this method, in order to quickly replace the first concave frame 10, mounting slots 16 are provided on the end sides of the four connecting arms 9. Mounting blocks 17 are fixedly installed in the four mounting slots 16 by bolts. One side of the four mounting blocks 17 is fixedly connected to the four first concave frames 10 respectively. The first concave frame 10 can be quickly removed and replaced by simply turning the bolts, thereby improving the replacement speed.

[0028] In this method, in order to wind up the twisted optical cable, a second concave frame 20 is fixedly installed on the slider of the first rodless cylinder 19, and a winding roller 21 is rotatably installed inside it. A second servo motor is fixedly installed on one outer wall of the second concave frame 20, and its output shaft is fixedly connected to one end of the winding roller 21. Furthermore, a fixing ring is fixed on the winding roller 21, and the twisted optical cable can be connected to the fixing ring, and then it can be wound up smoothly. The design of the first rodless cylinder 19 allows the winding roller 21 to reciprocate back and forth, ensuring that the winding process is neat and orderly.

[0029] In this method, in order to obtain a pre-stretched section of optical cable for easy fixing to the position of the fixing ring on the winding roller 21, a second rodless cylinder 22 is fixedly installed on the side of the support threading plate 2 away from the bearing plate 4. A push-bending rod 23 is fixedly installed on the slider of the second rodless cylinder 22. A third concave frame 24 is fixedly installed at the top of the push-bending rod 23. Two telescopic cylinders 25 are fixedly installed inside the third concave frame 24. Clamping pieces 26 are fixedly installed on the output shafts of the two telescopic cylinders 25. In addition, a limit bar is fixed inside the third concave frame 24. The limit bar passes through the two clamping pieces 26 and is slidably connected to the two clamping pieces 26. In the initial stranding operation, a small section of stranded optical cable can be obtained in advance by the operation of the second rodless cylinder 22. This section of optical cable can then be connected to the winding roller 21.

[0030] The working principle of the optical fiber cable steel wire stranding device provided by this utility model is as follows:

[0031] When it is necessary to twist the steel wire onto the optical fiber, first insert one end of the optical fiber into the optical fiber hole 6 and the bonding hole 3. Then, take out the ends of the steel wires from the two steel wire rolls 11 near the support threading plate 2, pass them through the two guide rings 18, and then through the bonding hole 3. At this time, the optical fiber is between the two steel wires, and the ends of the steel wires are aligned with the ends of the optical fiber. Then, start the output shaft of the telescopic cylinder 25 to extend, and the two clamping plates 26 move closer to each other, finally clamping the steel wire and the optical fiber.

[0032] Next, the drive motor is started, and its output shaft drives the gear to rotate. Through the meshing between the gear and the gear ring, the connecting disc 5 can be rotated. At this time, the two steel wires are wrapped around the optical fiber. Then, the second rodless cylinder 22 and the corresponding two first servo motors are started at the same time. The output shafts of the corresponding two first servo motors drive the corresponding steel wire roll 11 to rotate, thereby releasing the steel wire. At the same time, the slider on the second rodless cylinder 22 moves horizontally, thus forming a moving stranding operation. After the optical fiber and the steel wire are stranded for a certain length, the drive motor and the first servo motor are turned off. Then, the output shaft of the telescopic cylinder 25 is started to retract, loosening the stranded optical cable. Then, its end is connected to the fixing ring on the winding roller 21. Subsequently, the drive motor and the first servo motor are started again, and the second servo motor is started at the same time. In this way, the stranded optical cable can be wound onto the winding roller 21 during the moving stranding process. During the winding process, the first rodless cylinder 19 is started reciprocally, causing the slider on it to move back and forth, thereby making the winding more uniform.

[0033] In subsequent use, when it is necessary to replace the wire roll 11, first pause the machine briefly, then rotate the two threaded rods 14 to remove the two locking rods 15 from the corresponding locking grooves 12. Then, rotate the two bearing shafts 8 clockwise. After the two bearing shafts 8 have rotated 180°, screw the two threaded rods 14 to bring the two locking rods 15 back into the corresponding locking grooves 12. At this time, the two new wire rolls 11 are in the unwinding position. One person connects the ends of the wires on the new wire rolls 11 to the end of the optical fiber. At the same time, another person rotates the two bolts to remove the used wire roll 11 along with the first concave frame 10. Then, the first concave frame 10, which is the same as the new wire roll 11, is reinstalled on the connecting arm 9. At this time, the two sides are basically completed synchronously, and then the twisting work can continue.

[0034] In subsequent work, whenever the two wire rolls 11 in use are finished, the above steps can be followed, but the bearing shaft 8 needs to be used in a clockwise and counterclockwise manner to avoid the external wiring on the first servo motor getting tangled.

[0035] Compared with related technologies, the fiber optic cable steel wire stranding device provided by this utility model has the following beneficial effects:

[0036] This invention provides a fiber optic cable wire stranding device. By setting a bearing shaft 8 inside the mounting port 7 and two first concave frames 10 loaded with wire rolls 11 on the bearing shaft 8, the old and new wire rolls 11 can be quickly replaced by rotating the bearing shaft 8 after one wire roll 11 is used up. Furthermore, the used wire roll 11 is replaced at the same time as the wire end of the new wire roll 11 is connected to the fiber end, making full use of the roll replacement time. Compared with the traditional operation steps of first removing the wire roll 11, then installing the wire roll 11, and finally connecting the wire end to the fiber, this method makes full use of the roll replacement time, performing the roll replacement step and the wire end connection to the fiber simultaneously, thereby improving work efficiency to a certain extent.
