Description

Technical Field

[0001] The present invention relates to the technical field of optical fiber installation, and particularly relates to an efficient and stable network optical fiber installation and fixing device. Background Art

[0002] During the installation and erection of network optical fibers, it is necessary to lay optical fiber cables. During the laying process of optical fiber cables, the optical fiber cables need to be fixed on spaced utility poles to complete the wiring installation of the optical fiber cables.

[0003] Currently, when fixing optical fiber cables overhead on utility poles, usually a hoop is directly used to fix the optical fiber cables on the utility poles. When there are multiple optical fiber cables, they will be entangled with each other, thus affecting signal transmission. And in order to ensure the transmission performance of the optical fiber cables, when the cable passes through the fixing device, manual dragging is generally required. Manual dragging not only requires a certain amount of strength and patience, but also requires attention to avoid breaking or damaging the cable. Therefore, when threading the cable, the burden on the staff is relatively large, resulting in high requirements for the staff. For this reason, an efficient and stable network optical fiber installation and fixing device is proposed here. Summary of the Invention

[0004] The present invention is an efficient and stable network optical fiber installation and fixing device proposed to solve the problem of large manual threading burden in the prior art.

[0005] In order to achieve the above object, the present invention adopts the following technical scheme:

[0006] An efficient and stable network optical fiber installation and fixing device includes an optical fiber cable threading cylinder and a connection clamp assembly fixedly installed on the side wall of the optical fiber cable threading cylinder. The connection clamp assembly is used to be fixed to a utility pole, and further includes: a threading hole opened at an eccentric position of the optical fiber cable threading cylinder, and multiple groups of the threading holes are circumferentially distributed. The optical fiber cable passes through the threading holes; an installation ring, on which an adjustable wire clamping roller assembly is provided. After the optical fiber cable passes through the threading holes, it passes through the wire clamping roller assembly. A ratchet mechanism is provided in the wire clamping roller assembly. When the installation ring moves towards the optical fiber cable threading cylinder, the rollers in the wire clamping roller assembly rotate. When the installation ring moves away from the optical fiber cable threading cylinder, the rollers in the wire clamping roller assembly lock; an installation cavity is opened in the optical fiber cable threading cylinder, and a sealing sliding assembly is provided in the installation cavity, and the sealing sliding assembly is connected to the installation ring through a connection component.

[0007] As a preferred embodiment of the present invention: The clamp assembly includes a first clamp and a second clamp fixedly connected to the outer wall of the optical fiber cable threading cylinder. After the first clamp and the second clamp wrap the utility pole, they are fixed by fixing bolts.

[0008] As a preferred embodiment of the present invention: the wire clamping roller assembly includes a fixed wheel and an adjusting wheel. An installation groove is formed on the installation ring. The fixed wheel is rotatably connected in the installation groove. A mounting plate is fixedly connected to the installation ring. A mounting frame is fixedly connected to the mounting plate. A mounting shaft is fixedly connected to the mounting frame. The adjusting wheel is rotatably connected to the mounting shaft. An adjusting screw rod is threadedly connected to the installation ring, and the adjusting screw rod is rotatably connected to the mounting frame.

[0009] As a preferred embodiment of the present invention: the ratchet mechanism includes a ratchet tooth and an internal tooth ring. The internal tooth ring is fixedly connected to the inner side of the adjusting wheel. The ratchet tooth is rotatably connected to the mounting shaft, and the ratchet tooth meshes with the internal tooth ring.

[0010] As a preferred embodiment of the present invention: the sealing and sliding assembly includes a piston plate slidably connected in the installation cavity. A pushing and squeezing block is fixedly connected to the piston plate. An extrusion and fixing component is arranged on the optical fiber cable threading cylinder. When the installation ring moves away from the optical fiber cable threading cylinder and moves to the limit position, the squeezing block drives the fixing component to squeeze the optical fiber cable in the threading hole.

[0011] As a preferred embodiment of the present invention: the extrusion and fixing component includes a sliding rod slidably connected in the optical fiber cable threading cylinder. A groove is formed in the threading hole. A fixing block is arranged in the groove. The sliding rod extends into the groove and abuts against the fixing block. The sliding rod extends into the installation cavity and is fixedly connected with a wedge-shaped block. A spring is sleeved on the sliding rod. Two ends of the spring respectively abut against the wedge-shaped block and the inner wall of the installation cavity. When the installation ring moves away from the optical fiber cable threading cylinder and moves to the limit position, the squeezing block drives the wedge-shaped block and the sliding rod to move towards the threading hole.

[0012] As a preferred embodiment of the present invention: a rotating shaft is rotatably connected in the installation cavity. A crankshaft is fixedly connected to the rotating shaft. A crank is rotatably connected to the crankshaft. The crank is rotatably connected with the piston plate. A coupling is rotatably connected to the optical fiber cable threading cylinder. The coupling is fixedly connected with the rotating shaft.

[0013] As a preferred embodiment of the present invention: the connection component includes a connection shaft fixedly connected to the squeezing block. The connection shaft is fixedly connected to the installation ring. A connection seat is fixedly connected to the optical fiber cable threading cylinder. A pulley is rotatably connected to the connection seat. A sliding groove is formed in the connection shaft. The pulley abuts against the bottom of the sliding groove.

[0014] As a preferred embodiment of the present invention: an external thread is provided on the connecting shaft, a fixing nut is engaged with the external thread, a connecting groove is formed on the optical fiber cable threading cylinder, a gasket is clamped in the connecting groove, and after the optical fiber cable is installed, the fixing nut is rotated so that the fixing nut abuts against the gasket.

[0015] As a preferred embodiment of the present invention: a vent hole for communication is provided between the installation cavity and the threading hole, an installation hole is provided at one end of the installation cavity away from the installation ring, a pneumatic detection and alarm component is clamped on the installation hole, and the pneumatic detection and alarm component is hermetically arranged with the optical fiber cable threading cylinder. A ring groove is formed in the threading hole, and a sealing ring is clamped in the ring groove. When the optical fiber cable passes through the threading hole, the sealing ring and the optical fiber cable seal the threading hole. At the same time, during the reciprocating movement of the piston plate, the pneumatic detection and alarm component detects the peak air pressure inside the installation cavity and the threading hole.

[0016] Compared with the prior art, the present invention provides an efficient and stable network optical fiber installation and fixing device, which has the following beneficial effects:

[0017] 1. For this efficient and stable network optical fiber installation and fixing device, an external electric hydraulic drive device is used to drive the installation ring to reciprocate. When the installation ring moves in the first direction, the adjusting wheel and the fixing wheel rotate together under the action of the ratchet mechanism, so that the adjusting wheel and the fixing wheel slide on the optical fiber cable. When the adjusting wheel and the fixing wheel move in the second direction, the adjusting wheel locks, increasing the friction with the surface of the optical fiber cable, thereby dragging the optical fiber cable to move, driving the wire body at the rear end of the optical fiber cable to pass through the threading hole, and further enabling the optical fiber cable to automatically and smoothly pass through the threading hole, reducing the burden on the staff.

[0018] 2. For this efficient and stable network optical fiber installation and fixing device, six threading holes are arranged in a circumferential distribution and are all located at an eccentric position of the optical fiber cable threading cylinder, and this eccentric position is close to the edge of the optical fiber cable threading cylinder. When multiple optical fiber cables pass through the threading holes, the multiple threading holes organize the multiple optical fiber cables, preventing the multiple cables from being wound, avoiding cross-interference between the optical fibers, avoiding affecting the quality of signal transmission and increasing signal attenuation, and thus avoiding affecting the network performance.

[0019] 3. For this efficient and stable network optical fiber installation and fixing device, when the piston plate moves to the extreme limit in the first direction and is about to move in the second direction, the air pressure inside the installation cavity and the threading hole reaches the peak value. When a crack appears on the surface of the optical fiber cable, the peak value of the air pressure will change, that is, the air pressure will decrease. The comparison module determines that a crack has appeared on the optical fiber cable by comparing the peak values, and then an alarm is given through the alarm to prompt the staff to manually detect whether there is a problem with the optical fiber cable, facilitating timely repair or replacement to ensure that the laid optical fiber cable can be normal.

Detailed Description of the Invention

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0031] Example: Refer to Figures 1-8 A highly efficient and stable network optical fiber installation and fixing device comprises an optical fiber cable threading barrel 1 and a connecting clamping ring assembly fixedly mounted on the side wall of the optical fiber cable threading barrel 1, wherein the connecting clamping ring assembly is used to be fixed to a utility pole, wherein the clamping ring assembly comprises a first clamping ring 2 and a second clamping ring 3 fixedly connected to the outer wall of the optical fiber cable threading barrel 1, and the first clamping ring 2 and the second clamping ring 3 are fixed by fixing bolts 4 after covering the utility pole.

[0032] When in use, open the first clamp ring 2 and the second clamp ring 3, and then clamp the electric pole with the first clamp ring 2 and the second clamp ring 3. After the first clamp ring 2 and the second clamp ring 3 clamp the electric pole, screw on the fixing bolt 4, align the first clamp ring 2 and the second clamp ring 3, and thus fix the device on the electric pole.

[0033] Reference Figures 1-3 The optical fiber cable threading barrel 1 further comprises threading holes 5, which are arranged at eccentric positions of the optical fiber cable threading barrel 1. A plurality of threading holes 5 are distributed in a circle, and the optical fiber cable passes through the threading holes 5. One to eight threading holes 5 can be provided, and six are preferred in the present embodiment. The six threading holes 5 are distributed in a circle and are all arranged at eccentric positions of the optical fiber cable threading barrel 1, and the eccentric positions are close to the edges of the optical fiber cable threading barrel 1. When a plurality of optical fiber cables pass through the threading holes 5, the plurality of threading holes 5 can be used to organize the plurality of optical fiber cables, prevent the entanglement of the plurality of cables, avoid cross interference between optical fibers, avoid affecting the quality of signal transmission and increasing signal attenuation, thereby avoiding affecting network performance.

[0034] Reference Figure 2 , Figure 6 and Figure 8, further including an installation ring 26, on which an adjustable wire clamping roller assembly is provided. The optical fiber cable passes through the wire threading hole 5 and then through the wire clamping roller assembly. A ratchet mechanism is provided in the wire clamping roller assembly. When the installation ring 26 moves towards the optical fiber cable threading cylinder 1 (for the convenience of description, this moving direction is called the first direction), the rollers in the wire clamping roller assembly rotate. When the installation ring 26 moves away from the optical fiber cable threading cylinder 1 (for the convenience of description, this moving direction is called the second direction), the rollers in the wire clamping roller assembly are locked. Among them, the wire clamping roller assembly includes a fixed wheel 32 and an adjusting wheel 30. An installation groove 31 is formed on the installation ring 26. The fixed wheel 32 is rotatably connected in the installation groove 31. A mounting plate 27 is fixedly connected to the installation ring 26. A mounting frame 28 is fixedly connected to the mounting plate 27. A mounting shaft 29 is fixedly connected to the mounting frame 28. The adjusting wheel 30 is rotatably connected to the mounting shaft 29. An adjusting screw rod 33 is threadedly connected to the installation ring 26. The adjusting screw rod 33 is rotatably connected to the mounting frame 28. The ratchet mechanism includes a ratchet tooth 341 and an internal tooth ring 34. The internal tooth ring 34 is fixedly connected to the inner side of the adjusting wheel 30. The ratchet tooth 341 is rotatably connected to the mounting shaft 29. The ratchet tooth 341 meshes with the internal tooth ring 34

[0035] When threading the wire, pass the optical fiber cable through the wire threading hole 5, then through the fixed wheel 32 and the adjusting wheel 30. Then turn the adjusting screw rod 33 to drive the mounting frame 28 to move towards the fixed wheel 32, so that the fixed wheel 32 and the adjusting wheel 30 clamp the optical fiber cable together. Then, drive the installation ring 26 to reciprocate through an external electric hydraulic drive device (such as a hydraulic motor). When the installation ring 26 moves in the first direction, the adjusting wheel 30 and the fixed wheel 32 rotate together under the action of the ratchet mechanism, so that the adjusting wheel 30 and the fixed wheel 32 slide on the optical fiber cable. When the adjusting wheel 30 and the fixed wheel 32 move in the second direction, the adjusting wheel 30 is locked to increase the friction force with the surface of the optical fiber cable, thereby dragging the optical fiber cable to move, driving the wire body at the rear end of the optical fiber cable to pass through the wire threading hole 5, and further enabling the optical fiber cable to automatically and smoothly pass through the wire threading hole 5, reducing the burden on the staff

[0036] Refer to Figure 2 and Figure 7, the installation cavity 8 is opened in the optical fiber cable threading cylinder 1. A sealing sliding assembly is arranged in the installation cavity 8, and the sealing sliding assembly is connected to the installation ring 26 through a connecting assembly. The sealing sliding assembly includes a piston plate 12 slidably connected in the installation cavity 8. A pushing and squeezing block 13 is fixedly connected to the piston plate 12. An extrusion fixing assembly is arranged on the optical fiber cable threading cylinder 1. When the installation ring 26 moves away from the optical fiber cable threading cylinder 1 and moves to the limit position, the squeezing block 13 drives the fixing assembly to squeeze the optical fiber cable in the threading hole 5. A rotating shaft 9 is rotatably connected in the installation cavity 8. A crankshaft 91 is fixedly connected to the rotating shaft 9. A crank 11 is rotatably connected to the crankshaft 91. The crank 11 is rotatably connected to the piston plate 12. A coupling 10 is rotatably connected to the optical fiber cable threading cylinder 1. The coupling 10 is fixedly connected to the rotating shaft 9.

[0037] When in use, connect the output shaft of the hydraulic motor to the coupling 10, and then start the hydraulic motor. The hydraulic motor drives the rotating shaft 9 to rotate through the coupling 10. The rotating shaft 9 drives the crankshaft 91 to rotate. The crankshaft 91 drives the piston plate 12 to reciprocate inside the installation cavity 8 through the crank 11. The piston plate 12 drives the installation ring 26 to reciprocate through the squeezing block 13 and the connecting assembly, so as to intermittently drag the optical fiber cable and make the optical fiber cable stably pass through the threading hole 5.

[0038] Refer to Figure 2 and Figure 7 , the extrusion fixing assembly includes a sliding rod 14 slidably connected in the optical fiber cable threading cylinder 1. A groove is opened in the threading hole 5. A fixing block 17 (rubber block or silica gel block) is arranged in the groove. The sliding rod 14 extends into the groove and abuts against the fixing block 17. The sliding rod 14 extends into the installation cavity 8 and is fixedly connected with a wedge-shaped block 15. A spring 16 is sleeved on the sliding rod 14. The two ends of the spring 16 respectively abut against the wedge-shaped block 15 and the inner wall of the installation cavity 8. When the installation ring 26 moves away from the optical fiber cable threading cylinder 1 and moves to the limit position, the squeezing block 13 drives the wedge-shaped block 15 and the sliding rod 14 to move towards the threading hole 5.

[0039] After the squeezing block 13 moves to the limit position in the second direction, the squeezing block 13 drives the wedge-shaped block 15 to rise through the inclined surface. The wedge-shaped block 15 drives the sliding rod 14 to move towards the threading hole 5 and the spring 16 contracts. The sliding rod 14 squeezes the fixing block 17, so that the fixing block 17 squeezes the optical fiber cable, improving the friction force with the optical fiber cable, thereby improving the stability of fixing the optical fiber. When the squeezing block 13 moves in the first direction, the spring 16 resets, and the sliding rod 14 disengages from the fixing block 17, reducing the friction force between the fixing block 17 and the optical fiber cable.

[0040] Refer to Figure 2 , Figures 3-5, the connecting component includes a connecting shaft 18 fixedly connected to the extrusion block 13. The connecting shaft 18 is fixedly connected to the mounting ring 26. A connecting seat 21 is fixedly connected to the optical fiber cable threading cylinder 1. A pulley 22 is rotatably connected to the connecting seat 21. A sliding groove 20 is formed on the connecting shaft 18, and the pulley 22 is in contact with the bottom of the sliding groove 20. An external thread 19 is provided on the connecting shaft 18, and a fixing nut 25 is engaged with the external thread 19. A connecting groove 23 is formed on the optical fiber cable threading cylinder 1, and a gasket 24 is clamped in the connecting groove 23. After the optical fiber cable is installed, the fixing nut 25 is rotated so that the fixing nut 25 abuts against the gasket 24.

[0041] Through the cooperation of the pulley 22 and the sliding groove 20, the resistance when the connecting shaft 18 reciprocates can be reduced, and the resistance when dragging the optical fiber can be reduced. After the optical fiber is dragged, the fixing nut 25 is rotated to make the fixing nut 25 move towards the optical fiber cable threading cylinder 1 until the fixing nut 25 abuts against the gasket 24. At the same time, the crank 11 and the connecting shaft 18 are in a straight line (the mounting ring 26 moves to the extreme position in the second direction), so that the fixing block 17 abuts against the optical fiber cable, increasing the friction between the device and the optical fiber cable, quickly completing the fixing of multiple optical fiber cables, and improving the fixing efficiency.

[0042] Refer to Figures 1-7 , a vent hole 7 for communication is provided between the installation cavity 8 and the threading hole 5. An installation hole 81 is provided at one end of the installation cavity 8 away from the mounting ring 26. A pressure detection and alarm component 35 is clamped on the installation hole 81 (the pressure detection and alarm component 35 is composed of a pressure detection sensor, a comparison module, and an alarm. The pressure detection sensor is used to detect the air pressure in the installation cavity 8, the comparison module is used to compare the peak value of the air pressure, and the alarm is used to give an alarm), and the pressure detection and alarm component 35 is hermetically arranged with the optical fiber cable threading cylinder 1. Among them, the pressure detection and alarm component 35 and the optical fiber cable threading cylinder 1 are sealed by a sealing ring. A ring groove is formed in the threading hole 5, and a sealing ring 6 is clamped in the ring groove. When the optical fiber cable passes through the threading hole 5, the sealing ring 6 is sleeved on the optical fiber cable. Among them, the inner ring of the sealing ring 6 is in interference connection with the outer wall of the optical fiber cable, and the optical fiber cable seals the openings at both ends of the threading hole 5 communicating with the outside. At the same time, during the reciprocating movement of the piston plate 12, the pressure detection and alarm component 35 detects the peak value of the air pressure inside the installation cavity 8 and the threading hole 5 (this peak value is the value when the normal air inside the installation cavity 8 and the threading hole 5 moves to the extreme position in the first direction through the piston plate 12 and the installation cavity 8 and the threading hole 5 remain sealed).

[0043] When the piston plate 12 moves in the first direction, the device does not drag the optical fiber cable. At this time, the space inside the installation cavity 8 communicating with the threading hole 5 is in a sealed state. When the piston plate 12 moves to the extreme limit in the first direction and is about to move in the second direction, the air pressure inside the installation cavity 8 and the threading hole 5 reaches the peak value. When a crack appears on the surface of the optical fiber cable, the peak value of the air pressure will change, that is, the air pressure will decrease. The comparison module judges that there is a crack in the optical fiber cable by comparing the peak values, and then alarms through the alarm to prompt the staff to manually detect whether there is a problem with the optical fiber cable, which is convenient for timely maintenance or replacement. If a crack appears on the rubber layer on the surface of the optical fiber cable, its protection effect on the inside of the cable will be weakened, making the optical fiber cable more vulnerable to risks such as mechanical damage, moisture or chemical substance intrusion. Moreover, the crack may cause the rubber layer to lose its sealing property to a certain extent, exposing the optical fiber inside the cable to the external environment. In this way, the transmission of optical signals may be interfered with, affecting the transmission quality and reliability. Therefore, by comprehensively detecting the optical fiber cable during the laying process of the optical fiber cable, it can be ensured whether the laid optical fiber cable is normal.

[0044] After a crack appears on the surface of the optical fiber cable, the air in the installation cavity 8 and the threading hole 5 will be squeezed into the cable interior, reducing the air content inside the installation cavity 8 and the threading hole 5. In order to supplement the gas, when maintaining the optical fiber cable, the air pressure detection and alarm component 35 can be removed, then the piston plate 12 is driven to move to the extreme limit in the first direction, and then the piston plate 12 is driven to move to the extreme limit in the second direction, moving the cracked optical fiber cable to the outside of the optical fiber cable threading cylinder 1, which is convenient for the staff to detect. At the same time, the air pressure in the installation cavity 8 and the threading hole 5 returns to balance with the external air pressure, and then the air pressure detection and alarm component 35 is installed on the installation hole 81 and the air pressure detection and alarm component 35 is sealed with the optical fiber cable threading cylinder 1, so as to realize air supplementation for the installation cavity 8 and the threading hole 5.

[0045] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
