Description

Technical Field

[0001] The present invention provides a fiber optic cable coiling device and method for optical transmission equipment in a communication machine room, belonging to the technical field of fiber optic cable coiling equipment in a communication machine room. Background Art

[0002] As the core hub of a modern communication network, the optical transmission equipment in a communication machine room undertakes the key tasks of efficiently transmitting, switching, and processing optical signals. Such equipment connects communication nodes in different regions through fiber optic lines to achieve the fast and stable transmission of various types of information such as data, voice, and images, and is the cornerstone for ensuring the smooth operation of the communication network. In a communication machine room, a large number of optical transmission equipment work together, and the fiber optic cable, as an important medium for connecting various components inside these equipment and the equipment with external lines, its reasonable coiling management is directly related to the performance and maintenance efficiency of the equipment.

[0003] However, there are some drawbacks in the traditional fiber optic cable coiling method in a communication machine room. Currently, the fiber optic cables of most internal equipment in a communication machine room are bundled together using nylon cable ties and then wound around a coiling column to complete the coiling operation. Although this method achieves a preliminary arrangement of the fiber optic cables to a certain extent, it is prone to the problem of fiber optic cable entanglement, which not only affects the neatness of the internal wiring in the machine room but also increases the difficulty of subsequent maintenance work. Most importantly, the entanglement may cause a certain degree of extrusion deformation to the fiber optic cable. The fiber optic structure inside the fiber optic cable is relatively precise, and excessive extrusion may cause a change in the geometric shape of the fiber core, thereby causing abnormal scattering and refraction of the optical signal during propagation, resulting in an increase in signal attenuation and ultimately affecting the transmission efficiency and quality. Secondly, during use, once a group of fiber optic cables fails, the first task faced by maintenance personnel is to remove the nylon cable ties bundling the fiber optic cables. The removal process is cumbersome, time-consuming, and laborious, which greatly extends the maintenance time and seriously interferes with the normal and stable operation of communication services. After removal, quickly and accurately locating the faulty fiber optic cable among numerous fiber optic cables is undoubtedly a very challenging task. Even more seriously, due to the large number and disorder of fiber optic cables, maintenance personnel may accidentally operate on the normally operating fiber optic cables with a slight carelessness, causing accidental damage. This secondary damage is very likely to trigger a chain reaction, resulting in the interruption of other communication links and thus causing large-scale communication failures, which will not only bring huge economic losses to communication operators but also have an immeasurable negative impact on their service quality and market reputation.

[0004] Therefore, it is necessary to provide a new fiber optic cable coiling device for optical transmission equipment in a communication machine room to solve the above technical problems. Summary of the Invention

The angle between two adjacent push rods 10 is the same as the angle between two adjacent card slots two 47.

[0034] In this embodiment, the angle between two adjacent push rods 10 is set as one unit, and the tooth number ratio of the gear 25 to the first rack 27 is 1:2. Since the transmission ratio of the driving pulley 22 to the driven pulley 24 is 1:8, when the rotating rod 4 rotates, it drives the sliding cylinder 18 to rotate one unit in the sleeve 17, so that the driving pulley 22 rotates one unit, and the driven pulley 24 rotates eight units accordingly. The driven pulley 24 drives the gear 25 to rotate eight units through the vertical rod 23. The rotation of the gear 25 causes the first rack 27 to move along the radial direction of the gear 25, and further causes the pressing block 28 on the first rack 27 to move a distance corresponding to eight units to the vicinity of an adjacent set of fiber splicing column assemblies, so that the pressing block 28 is located above the third rack 32 connected to the fiber splicing column assembly.

[0035] A spherical head structure is integrally formed at the end of the push rod 10 away from the push plate 7. The spherical head structure corresponds to the inclined surface at the bottom of the pressure rod 15. The spherical head structure, the pressure rod 15 and the frustum 16 cooperate with each other. Under the action of the rotating rod 4, the push rod 10 can be pushed and pulled to control the relative position of the two clamping plates 13, that is, to control the opening and closing state of the two clamping plates 13. A plurality of first card slots are provided on the side wall of the push rod 10. In this embodiment, four first card slots are provided. Two first card slots are a group, and the two groups of first card slots are respectively located on the opposite side walls of the push rod 10. The first card slots can be clamped with the first clamping blocks 12. The distance between two opposite first card slots on the two side walls of the push rod 10 is the same as the distance between the upper surface of the first convex block 46 and the inner top of the sliding cylinder 18, that is, the distance between two opposite first card slots on the two side walls of the push rod 10 is the same as the distance that the rotating rod 4 can move upward in the sliding cylinder 18.

[0036] When the push rod 10 is pushed to move away from the rotating rod 4, the side wall of the push rod 10 presses against the first clamping block 12, and the first clamping block 12 slides in the spring groove, thereby compressing the first spring 11 fixedly connected to the first clamping block 12. Continuing to push the push rod 10, when the first clamping block 12 is opposite to the first clamping groove on the side close to the rotating rod 4, the corresponding first spring 11 releases elastic force, and the first spring 11 pushes the first clamping block 12 to slide in the spring groove, so that the first clamping block 12 is clamped in the first clamping groove on the side close to the rotating rod 4. At the same time, the push rod 10 pushes the push plate 7 to move away from the rotating rod 4. During the movement of the push plate 7, the clamping plate 14 rotates in the fitting groove 43, driving the two clamping plates 13 to rotate away from each other, so that the two clamping plates 13 are separated. At this time, the operator can place the optical fiber pigtail in the clamping seat 6.

[0037] When the push rod 10 moves away from the clamping seat 6, the first clamping block 12 disengages from the first clamping groove on the side close to the rotating rod 4, and the side wall of the push rod 10 presses against the first clamping block 12 again. Continuing to move the push rod 10, when the first clamping block 12 is opposite to the first clamping groove on the side away from the rotating rod 4, the corresponding first spring 11 releases elastic force, causing the first clamping block 12 to be clamped in the first clamping groove. At the same time, the push rod 10 drives the push plate 7 to move away from the clamping seat 6, and the clamping plate 14 rotates reversely in the fitting groove 43, driving the two clamping plates 13 to rotate towards each other, so that the two clamping plates 13 approach and abut against each other, thereby fixing the optical fiber pigtail between the clamping seat 6 and the clamping plates 13 to complete the initial fixation.

[0038] After the optical fiber pigtail is led out from the lower end of the clamping seat 6, it is wound around the fiber optic coiling post 3. The clamping assembly and the two fixed clamping plates 9 fixedly connected to the mounting plate 52 cooperate to clamp the optical fiber pigtail wound around the fiber optic coiling post 3 and prevent it from loosening. Each group of optical fiber pigtails is operated according to this process in sequence and fixed on the corresponding fiber optic coiling post 3 to complete the fiber optic coiling operation, which also brings convenience to subsequent maintenance.

[0039] A indicating needle 55 is fixedly connected to the pressing rod 15 near the top of the rotating rod 4, and the indicating needle 55 points to any one of the clamping seats 6.

[0040] To facilitate the operator to move the rotating rod 4 up and down and rotate it around the axis of the rotating rod 4, a holding part 42 is integrally formed at the top of the rotating rod 4.

[0041] A method for coiling optical fiber pigtails of an optical transmission device in a communication machine room provided by the present invention adopts the above-mentioned device for coiling optical fiber pigtails of an optical transmission device in a communication machine room.

[0042] The working principle of the present invention: In the initial state, the first spring 11, the second spring 20 and the third spring 19 inside the device for coiling optical fiber pigtails of an optical transmission device in a communication machine room of the present invention are all in an unloaded state, and the tension spring 39 is in a stretched state.

[0043] When it is necessary to organize the pigtail, the operator holds the holding part 42 at the top of the rotating rod 4 and pulls it upward, driving the frustum 16 fixedly connected to the rotating rod 4 to move upward. The side wall of the frustum 16 squeezes the push rod 10 to move away from the rotating rod 4, that is, the push rod 10 pushes the push rod 10 to move away from the rotating rod 4. The clamping plate 14 rotates in the fitting groove 43, driving the two clamping plates 13 to rotate away from each other, so that the two clamping plates 13 are separated. At this time, the operator can place the pigtail in the clamping seat 6. Then, press the push plate 7 downward, so that the push rod 10 moves reversely along the sixth through hole, that is, the push rod 10 moves away from the clamping seat 6 along the sixth through hole. The clamping plate 14 rotates reversely in the fitting groove 43, driving the two clamping plates 13 to rotate towards each other, so that the two clamping plates 13 approach each other and abut, thereby fixing the pigtail between the clamping seat 6 and the clamping plate 13 to complete the initial fixation. After the pigtail passes through the lower end of the clamping seat 6, it is wound around the corresponding fiber coiling column assembly. After the winding is completed, push the toothed plate 36 towards the direction where the rotating rod 4 is located, thereby driving the second toothed column 37 meshing with it to rotate, driving the connecting rod 38 to rotate. The connecting rod 38 drives the moving clamping plate 8 to rotate. The pushing member 40 on the moving clamping plate 8 cooperates with the V-shaped groove 41 opened at the bottom of the toothed plate 36, so that the two moving clamping plates 8 move towards each other during the rotation. At this time, the tension springs 39 sleeved at both ends of the connecting rod 38 release the tension, pulling the corresponding moving clamping plates 8 to approach each other along the axial direction of the connecting rod 38. When the moving clamping plate 8 rotates 90°, the moving clamping plate 8 is perpendicular to the mounting seat 2, and cooperates with the fixed clamping plate 9 to clamp the pigtail wound around the fiber coiling column assembly to prevent it from loosening, thus completing the fiber coiling operation.

[0044] During operation, when a group of pigtails fixed in the clamping seat 6 needs to be inspected, the operator holds the holding part 42 on the top of the rotating rod 4 and rotates it to make the indicator needle 55 point to the direction of the pigtail that needs to be inspected, and then pushes the rotating rod 4 downward. The movable rod slides downward inside the slide 18 and compresses the spring three 19. At the same time, the pressure rod 15 and the round table 16 fixedly connected on the rotating rod 4 move downward. During the downward movement, the pressure rod 15 squeezes the spherical head structure of the corresponding push rod 10, so that the push rod 10 moves toward the clamping seat 6, driving the push plate 7 to move toward the clamping seat 6. The clamping plate 14 cooperates with the mating groove 43 to separate the two clamping plates 13. At this time, the pigtail clamped between the clamping seat 6 and the clamping plate 13 is released. At the same time, the rotation of the rotating rod 4 drives the active pulley 22 fixedly connected to its bottom to rotate, and the driven pulley 24 connected to the active pulley 22 rotates accordingly, so that the driven pulley 24 drives the gear 25 to rotate through the vertical rod 23, and then drives the rack 1 27 engaged with the gear 25 to move along the radial direction of the gear 25, so that the pressure block 28 on the rack 1 27 moves to the vicinity of the fiber coil column assembly corresponding to the pigtail that needs to be repaired, so that the pressure block 28 is located above the rack 3 32 connected to the fiber coil column assembly. When the two movable splints 8 are rotated 90 degrees in the opposite direction, the movable splint 8 and the mounting plate 52 are parallel to each other and are perpendicular to the disk fiber column 3, so that the movable splint 8 can be placed in the mounting groove on the mounting plate 52. At this time, the group of faulty pigtails is completely free from the constraints of the fiber coiling mechanism, making it easier for the operator to repair it.
