Description

Technical Field

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

[0002] An optical fiber cable is a telecommunications device used to transmit optical signals. It consists of one or more optical fibers, transmitting signals through reflection and refraction within the fibers. An optical fiber cable typically consists of an optical fiber core, cladding, and sheath. During the laying of optical fiber cables, the distance is usually over a hundred meters. To improve construction efficiency and reduce the labor intensity of workers, a traction device is typically used to move the optical fiber cable, assisting in the construction process.

[0003] In response to this, Chinese Patent No. CN 221550983 U proposes an auxiliary traction device for threading and releasing communication optical cables. This device inserts the optical cable into the feeding trough, connects the rotating handle to the docking shaft, and rotates the docking shaft to cause the traction roller to rotate within the feeding trough. This causes one side of the optical cable to be engaged in a groove, and under the rotation of the traction roller, it moves forward in the traction machine, exiting from the discharge trough and entering the designated connection area for threading and releasing. During use, rotating the protective cover with the handle causes the locking shaft to engage with the inner wall of the traction machine, securing the cable and protecting the upper end of the traction roller from impact damage, thereby improving the practicality of the device.

[0004] The above has the following shortcomings: When the optical cable traction device is in use, dust will accumulate on the surface of the optical cable, which will then adhere to the internal structure of the traction device. The dust, combined with moisture in the air, will corrode the internal structure, thus affecting the use of the traction device. Utility Model Content

[0005] The purpose of this invention is to provide an optical cable pulling device that integrates a cleaning and dust extraction structure to solve the problem of dust entering the optical cable surface and causing corrosion.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an optical cable traction device, including a cable threading mechanism, the cable threading mechanism including a cable threading tube, a traction channel opened on the cable threading tube, a traction roller provided on the cable threading tube, and a rotating handle for driving the traction roller to rotate, a cleaning mechanism is provided in the traction channel, and the cleaning mechanism is provided on both sides of the traction roller.

[0007] By adopting the above technical solution, and by setting up a cable laying mechanism, the optical cable is stably pulled by the rotation of the traction rollers. At the same time, the cleaning mechanism can clean the surface of the optical cable during the pulling process, which effectively improves the efficiency and quality of optical cable laying, ensures the cleanliness of the optical cable during the laying process, reduces subsequent cleaning work, and improves the overall work efficiency.

[0008] The cleaning mechanism is further configured as follows: a rotating ring is rotatably disposed in the traction channel for the optical cable to pass through, a cleaning ring is detachably disposed inside the rotating ring, and a drive assembly for driving the rotating ring to rotate.

[0009] By adopting the above technical solution, the cleaning mechanism ensures that the cleaning ring closely adheres to the surface of the optical cable as it passes through the traction channel, effectively cleaning dust and impurities from the cable surface. The rotatability of the ring guarantees the continuity and uniformity of cleaning, improving the cleaning effect. Simultaneously, the cleaning ring is detachable, facilitating replacement and maintenance, reducing operating costs, and enhancing the practicality of the device.

[0010] A further configuration is provided: a Velcro fastener is fixedly provided on the inner side of the rotating ring, and the cleaning ring is attached to the Velcro fastener.

[0011] By adopting the above technical solution and using Velcro connections, the replacement of cleaning rings becomes simple and quick. During the fiber optic cable laying process, when the cleaning ring wears out and needs to be replaced, no complicated tools or cumbersome operations are required; simply unfasten the Velcro and replace the new cleaning ring. This greatly improves maintenance efficiency, reduces equipment downtime, and ensures the continuity of fiber optic cable laying operations.

[0012] The drive assembly is further configured as follows: each rotating ring has a toothed ring on its outer circumference, a linkage shaft for synchronously controlling the two toothed rings, a first rotating shaft fixedly mounted on the traction roller, and a second rotating shaft disposed between the linkage shaft and the first rotating shaft. A first gear is fixedly mounted at both ends of the linkage shaft, and the first gear meshes with the corresponding toothed ring. A second gear is fixedly mounted on the first rotating shaft, and a third gear is fixedly mounted at both ends of the second rotating shaft. A fourth gear is also fixedly mounted on the linkage shaft, and the two third gears mesh with the corresponding fourth gear and the second gear, respectively.

[0013] By adopting the above technical solution and through the design of this drive component, the rotation of the traction roller can be effectively transmitted to the rotating ring, enabling the rotating ring to rotate synchronously with the traction roller. In this way, during the traction of the optical cable, the cleaning ring can continuously and stably clean the surface of the optical cable, achieving simultaneous traction and cleaning, improving work efficiency, avoiding the problems of increased power source and equipment complexity that might arise from driving the rotating ring alone, simplifying the equipment structure, and reducing equipment costs.

[0014] The device is further configured such that: a dust suction hood is provided at the bottom of the threading spool, the dust suction hood is tapered from top to bottom, the top of the dust suction hood is threadedly connected to the bottom of the threading spool, and an air suction pump is fixedly provided at the bottom of the dust suction hood.

[0015] By adopting the above technical solution, the dust hood can promptly collect dust and impurities generated during the cleaning process, preventing them from scattering into the air and causing environmental pollution and harm to the health of operators. The top-to-bottom tapering structure helps to concentrate dust collection, improving collection efficiency. The threaded connection makes the dust hood easy to disassemble, facilitating cleaning and maintenance of the interior, ensuring consistent dust collection performance, and also making it easy to install and replace, thus improving the maintainability of the equipment.

[0016] The dust collection hood is further configured such that: a metal mesh is provided on the top of the dust collection hood, and multiple layers of filter paper are provided inside the dust collection hood; both the metal mesh and the multiple layers of filter paper have a detachable structure from the dust collection hood.

[0017] By adopting the above technical solution, the metal mesh can block larger particles of impurities, preventing them from directly entering the filter paper and causing blockage, thus extending the filter paper's lifespan. The filter paper, in turn, can further filter out fine particles in the air, ensuring the cleanliness of the exhaust air and meeting environmental protection requirements. The detachable design of the metal mesh and filter paper facilitates regular cleaning or replacement, ensuring the long-term stable operation of the dust collection system and reducing equipment operating costs.

[0018] The detachable structure is further configured to include a first embedding groove on the dust cover for embedding a metal mesh and a second embedding groove on the dust cover for embedding multiple layers of filter paper.

[0019] By adopting the above technical solution, this embedded, detachable structure makes the installation and removal of the metal mesh and filter paper more convenient and quick. Maintenance personnel do not need to use additional fixing tools; they can simply embed the metal mesh and filter paper into the corresponding slots to complete the installation. Disassembly is as simple as removing them directly, greatly improving maintenance efficiency, reducing equipment maintenance time and workload, and enhancing equipment availability.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] refer to Figures 1 to 4 A fiber optic cable pulling device includes a cable threading mechanism 1. The cable threading mechanism 1 includes a cable threading drum 11, a pulling channel 12 opened on the cable threading drum 11, a pulling roller 13 installed on the cable threading drum 11, and a rotating handle 15 for driving the pulling roller 13 to rotate. A cleaning mechanism is installed inside the pulling channel 12. The cable threading drum 11 is designed as a cylindrical structure. The pulling channel 12 is opened along the central axis of the cable threading drum 11. The inner diameter of the pulling channel 12 is slightly larger than the outer diameter of the fiber optic cable to ensure that the fiber optic cable can pass through smoothly. The pulling roller 13 is installed at the top of the cable threading drum 11. The rotating handle 15 is welded to the hub of the pulling roller 13 to facilitate the operator to apply force. The cleaning mechanism is installed inside the pulling channel 12, located on both sides of the pulling roller 13, symmetrically distributed to ensure all-round cleaning of the fiber optic cable.

[0027] The cleaning mechanism includes a rotating ring 21 that is rotatably installed in the traction channel 12 for the optical cable to pass through, a cleaning ring 22 that is detachably installed inside the rotating ring 21, and a drive assembly that drives the rotating ring 21 to rotate. The rotating ring 21 is circular in shape, made of nylon engineering plastic, and has a certain elasticity, which can closely fit the surface of the optical cable. Its inner diameter matches the outer diameter of the optical cable.

[0028] A layer of strong adhesive is evenly applied to the inner surface of the swivel ring 21, and the hook side of the hook and loop fastener 31 is firmly attached to the inner side of the swivel ring 21. The cleaning ring 22 is then attached to the hook and loop fastener 31. The outer side of the cleaning ring 22 has a textured surface that matches the hook and loop fastener 31. Through the adhesive action of the hook and loop surfaces, the cleaning ring 22 is fixed to the inner side of the swivel ring 21. This method of attachment is convenient to install and provides a firm bond, preventing the cleaning ring 22 from loosening during optical cable pulling. It also facilitates the replacement of the cleaning ring 22; simply peel off the old cleaning ring 22 and attach the new one.

[0029] The drive assembly includes a toothed ring 51 on the outer circumference of each rotating ring 21, a linkage shaft 52 for synchronous control of the two toothed rings 51, a first rotating shaft 53 fixedly mounted on the traction roller 13, and a second rotating shaft 54 ​​between the linkage shaft 52 and the first rotating shaft 53. A first gear 55 is fixedly mounted at both ends of the linkage shaft 52, and the first gear 55 meshes with the corresponding toothed ring 51. A second gear 56 is fixedly mounted on the first rotating shaft 53, and a third gear 57 is fixedly mounted at both ends of the second rotating shaft 54. A fourth gear 58 is also fixedly mounted on the linkage shaft 52. The two third gears 57 mesh with the corresponding fourth gear 58 and the second gear 56, respectively. Through the meshing relationship between the gears, the power of the first rotating shaft 53 is transmitted to the linkage shaft 52, thereby driving the rotating ring 21 to rotate.

[0030] A dust collection hood 59 is installed at the bottom of the threading spool 11. The dust collection hood 59 tapers from top to bottom, and its top is threadedly connected to the bottom of the threading spool 11. An air suction pump 50, which is a small centrifugal fan, is fixed to the bottom of the dust collection hood 59 with bolts. The air inlet of the air suction pump 50 is connected to the bottom of the dust collection hood 59, and its outlet is connected to an external exhaust system via a pipe. A metal mesh 61 is installed on the top of the dust collection hood 59, and multiple layers of filter paper 62 are installed inside the dust collection hood 59. Both the metal mesh 61 and the multiple layers of filter paper 62 are detachable from the dust collection hood 59. The multiple layers of filter paper 62 consist of three layers of filter paper with different precision. The detachable structure includes a first embedding groove 71 and a second embedding groove 72 formed on the dust collection hood 59. The edge of the metal mesh 61 is processed with a flange and is embedded in the first embedding groove 71 to prevent the metal mesh 61 from loosening during the dust collection process. The second embedding groove 72 is located inside the dust collection hood 59 and is used to embed multiple layers of filter paper 62 to prevent the metal mesh 61 from loosening during the dust collection process.

[0031] Overall workflow: First, the optical cable is threaded through the traction channel 12 at one end of the cable threading tube 11, and then passes sequentially through the rotating ring 21 and cleaning ring 22 of the cleaning mechanism. The operator holds the rotating handle 15 and rotates the traction roller 13. During rotation, the traction roller 13 drives the optical cable forward through friction. At the same time, the rotation of the traction roller 13 is transmitted to the gear ring 51 through the first rotating shaft 53, the second gear 56, the second rotating shaft 54, the third gear 57, the fourth gear 58, the linkage shaft 52, and the first gear 55 in the drive assembly, thereby driving the rotating ring 21 to rotate synchronously, and the cleaning ring 22 cleans the surface of the optical cable accordingly. Dust and impurities generated during the cleaning process are sucked in by the suction pump 50 through the dust suction hood 59, filtered by the metal mesh 61 and multiple layers of filter paper 62, and then discharged to ensure a clean working environment. When the cleaning ring 22 wears out and needs replacement, simply unfasten the Velcro 31, remove the old cleaning ring 22, replace it with a new one, and re-attach it. When cleaning the dust inside the vacuum hood 59 or replacing the filter paper, unscrew the vacuum hood 59, remove the metal mesh 61 and filter paper, and perform the corresponding operations. The operation is very convenient. During operation, all components of the device work together to achieve efficient traction and cleaning of the optical cable, while ensuring good environmental performance and ease of maintenance.
