For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0031] See also Figure 1 and Figure 2 An embodiment of the present application provides an optical cable threading device 100, which is used to be sleeved on an optical cable 40 to be installed and a supporting cable 10, the supporting cable 10 includes a plurality of hooks 11, and the optical cable threading device 100 includes a sleeve structure 20 and a connecting assembly 30.

[0032] The sleeve structure 20 is used to be sleeved on the supporting cable 10 .

[0033] The connecting component 30 is arranged in the sleeve structure 20 and is used to be sleeved on the optical cable 40 to be installed. The connecting component 30 includes a plurality of first connecting members 31 and a plurality of second connecting members 32. The first connecting members 31 are fixedly connected to the sleeve structure 20, and the second connecting members 32 are used to fix the connection to the optical cable 40 to be installed. The diameter size of the first connecting member 31 is larger than the diameter size of the hook 11, and the diameter size of the second connecting member 32 is smaller than the diameter size of the hook 11.

[0034] In the working state, at least one first connecting member 31 is engaged with one of the second connecting members 32 .

[0035] The optical cable threading device 100 provided in the embodiment of the present application is configured such that in the connecting assembly 30, the diameter size of the first connecting member 31 is larger than the diameter size of the hook 11, and the first connecting member 31 can pass through the hook 11, and the diameter size of the second connecting member 32 is smaller than the diameter size of the hook 11, and the hook 11 can pass through the second connecting member 32; the second connecting member 32 can pull the optical cable 40 to be installed to pass through the hook 11, and in the working state, at least one first connecting member 31 is configured to be engaged with a second connecting member 32, and the first connecting member 31 can be driven by pulling the sleeve structure 20, and the second connecting member 32 can be driven by the first connecting member 31, so that the optical cable can pass through the hook 11, and the optical cable is protected while the device structure is simple and the operation efficiency is high.

[0036] The existing optical cable installation scheme generally includes a supporting cable 10 and a plurality of optical cables 40 to be installed, and the supporting cable 10 includes a plurality of hooks 11. Each time a new optical cable 40 to be installed is attached, since a plurality of optical cables 40 to be installed are already attached to the supporting cable 10, and a plurality of hooks 11 are already deployed on the plurality of optical cables 40 to be installed, if a new optical cable 40 to be installed needs to be attached to the supporting cable 10, it is necessary to adopt an installation scheme of untying the hook 11, merging the new optical cable 40 to be installed with the original optical cable 40 to be installed, and then reinstalling the hook 11, or adopting an installation scheme of not untying the original hook 11, and directly installing the new optical cable 40 to be installed and the new hook 11 on the basis of the original supporting cable 10, the original hook 11 and the original optical cable 40 to be installed. In the existing optical cable installation scheme, either the operation is complicated and cumbersome, or the new and old optical cables 40 to be installed overlap with the hook 11, which easily causes squeezing and wear of the optical cable 40 to be installed, and makes it difficult to maintain the optical cable 40 to be installed, causing maintenance problems.

[0037] In the existing optical cable installation technology, a method is usually adopted to complete the installation of the optical cable 40 to be installed by passing the optical cable 40 through the hook 11 on the supporting cable 10. However, the current optical cable installation device is too complicated and has low operating efficiency.

[0038] The main working area in the optical cable threading device 100 is the partial segment of the supporting cable 10 on which the sleeve structure 20 is sleeved. In addition to protecting other structures inside for threading the optical cable 40 to be installed on the hook 11 of the supporting cable 10, the sleeve structure 20 also serves to define the installation work area, making it convenient for the staff to directly adjust the position of the sleeve structure 20 and smoothly pass the optical cable 40 to be installed through the hook 11 on the partial segment of the supporting cable 10 in each working area.

[0039] In the connecting assembly 30, the first connecting member 31 is fixedly connected to the sleeve structure 20, and the second connecting member 32 is used to fixedly connect the optical cable 40 to be installed. In the working state, it is ensured that at least one first connecting member 31 is engaged with a second connecting member 32. The position of the sleeve structure 20 can be directly adjusted to drive the first connecting member 31 to adjust its position, and then drive the second connecting member 32 to adjust its position, and finally adjust the position of the optical cable 40 to be installed, so that the optical cable 40 to be installed can smoothly pass through all the hooks 11 on the supporting cable 10.

[0040] Among them, the diameter size of the first connecting member 31 is larger than the diameter size of the hook 11, so that the hook 11 can pass through both the sleeve structure 20 and the first connecting member 31, and there will be no conflict and interference between the hook 11 and the sleeve structure 20 and the first connecting member 31, causing the optical cable threading device 100 and the hook 11 to get stuck.

[0041] The diameter of the second connecting piece 32 is smaller than the diameter of the hook 11, so that the cable to be installed and the second connecting piece 32 can pass through the hook 11 smoothly. There will be no conflict or interference between the hook 11 and the cable to be installed and the second connecting piece 32, which will cause the optical cable threading device 100 and the hook 11 to get stuck.

[0042] In the working state, it is ensured that at least one first connecting member 31 is engaged with one second connecting member 32, so that the movement of the sleeve structure 20 can drive the movement of the optical cable 40 to be installed.

[0043] The working state here should be understood as follows: first, the connecting component 30 is arranged in the sleeve structure 20, the connecting component 30 is connected to the sleeve structure 20 through the first connecting member 31 and is connected to the optical cable 40 to be installed through the second connecting member 32, and the optical cable threading device 100 is arranged and sleeved on the optical cable 40 to be installed and the supporting cable 10 to complete the optical cable threading work.

[0044] Secondly, in the working state, the optical cable threading device 100 can normally complete the threading work, that is, at least the sleeve structure 20 must be able to drive the optical cable 40 to be installed to move. Therefore, in the working state, it is necessary to ensure that at least one first connector 31 and one second connector 32 are connected.

[0045] Exemplarily, the working state should also be understood as that even if the optical cable threading device 100 is set and sleeved in the optical cable 40 to be installed and the supporting cable 10, the working state of the optical cable threading device 100 is interrupted due to an unexpected situation that causes no first connector 31 and second connector 32 to be in a state of being engaged. When waiting for at least one first connector 31 and second connector 32 to be engaged, the optical cable threading device 100 returns to the working state.

[0046] See also Figure 1 and Figure 2 In some embodiments, the number of the second connectors 32 is greater than the number of the first connectors 31 , the first connectors 31 are arranged at the same distance along the sleeve structure 20 , and the second connectors 32 are arranged at the same distance along the optical cable 40 to be installed.

[0047] In these embodiments, the optical cable threading device 100 provided in the embodiments of the present application, by setting the number of second connectors 32 to be greater than the number of first connectors 31, ensures that in the working state, even if the first connector 31 is disconnected from the second connector 32 originally arranged in cooperation, it can be quickly connected with the second connector 32 adjacent to the second connector 32 originally arranged in cooperation with other first connectors 31, and ensures as much as possible that at least one first connector 31 is connected to one second connector 32, completing the installation process of the optical cable 40 to be installed passing through the hook 11, so that the optical cable threading device 100 can continue to be used normally.

[0048] By arranging the first connecting members 31 at the same intervals along the sleeve structure 20 , the first connecting members 31 can cover the working area of ​​the optical cable threading device 100 as evenly as possible, so that the entire sleeve structure 20 is subjected to uniform force when moving.

[0049] By arranging the second connectors 32 to be arranged at the same distance along the optical cable 40 to be installed, the second connectors 32 can cover the optical cable 40 to be installed as evenly as possible, so that after the first connector 31 is disconnected from the second connector 32 originally matched, the first connector 31 can be at the same distance as far as possible from the nearest adjacent second connector 32 on the optical cable 40 to be installed. When the sleeve structure 20 is pulled at a uniform speed, the time required for the first connector 31 to re-engage with the nearest second connector 32 is roughly the same, ensuring that the optical cable threading device 100 can quickly enter the working state from the interruption of the working state, and ensuring that at least one first connector 31 is engaged with one second connector 32.

[0050] See also Figure 1 and Figure 2 In some embodiments, the number of the first connecting members 31 is four, and the number of the second connecting members 32 is eight.

[0051] In these embodiments, the optical cable threading device 100 provided in the embodiments of the present application, by specifically setting the number of first connecting members 31 to four and the number of second connecting members 32 to eight, ensures that the entire sleeve structure 20 can be evenly stressed when moving, and the gravity of the first connecting member 31 itself will not affect the stress on the entire sleeve structure 20.

[0052] The number ratio of the second connecting members 32 to the first connecting members 31 is 2:1. Among all the second connecting members 32, in addition to a second connecting member 32 originally matched with the first connecting member 31, there is also a spare second connecting member 32 reserved for the first connecting member 31. After the first connecting member 31 is disconnected from the second connecting member 32 originally matched with the first connecting member 31, it can also slide to the spare second connecting member 32 reserved and engage with it, thereby ensuring that the optical cable threading device 100 can quickly enter the working state from the interruption of the working state, thereby ensuring that at least one first connecting member 31 is engaged with a second connecting member 32.

[0053] Please continue reading Figure 1 and Figure 2 In some embodiments, the first connecting member 31 is an elastic structure, including an annular body 311 and a plurality of elastic connecting parts 312 annularly distributed along the annular body 311. The annular body 311 has the same diameter as the sleeve structure 20 and is larger than the diameter of the hook 11. The annular body 311 is fixedly connected to the sleeve structure 20.

[0054] In the working state, at least one elastic connection portion 312 is engaged with a second connection member 32 .

[0055] In these embodiments, the optical cable threading device 100 provided in the embodiments of the present application can better fix the first connecting member 31 to the sleeve structure 20 by setting the diameter size of the annular body 311 to be the same as the diameter size of the sleeve structure 20.

[0056] By setting the diameter of the annular body 311 to be larger than the diameter of the hook 11, the hook 11 can pass through the annular body 311 in the first connecting member 31 while the hook 11 cannot pass through the elastic connecting portion 312. The hook 11 will contact the elastic connecting portion 312 in the first connecting member 31 and lift up the elastic connecting portion 312, thereby disconnecting the elastic connecting portion 312 from the second connecting member 32.

[0057] In the working state, at least one elastic connecting portion 312 is ensured to be engaged with a second connecting member 32 , so that the sleeve structure 20 can be driven to move, thereby driving the optical cable 40 to be installed to move, thereby completing the installation process of the optical cable 40 to be installed passing through the hook 11 .

[0058] Please continue reading Figure 1 and Figure 2 In some embodiments, a hook structure 3121 is provided at the end of the elastic connecting portion 312 .

[0059] In the working state, at least one elastic connection portion 312 is engaged with a second connection member 32 via the hook structure 3121 .

[0060] In these embodiments, the optical cable threading device 100 provided in the embodiments of the present application, by setting a hook-like structure 3121, the elastic connecting portion 312 can be clamped with the second connecting member 32 through the hook-like structure 3121, and when the first connecting member 31 passes through the hook 11, while the hook 11 passes through the annular body 311, the hook 11 can lift the elastic connecting portion 312 in the first connecting member 31, and the hook-like structure 3121 at the end of the elastic connecting portion 312 can be disconnected from the second connecting member 32, and when the elastic connecting portion 312 returns to its original state, the hook-like structure 3121 at the end can be re-clamped with the second connecting member 32, and the connection reliability between the elastic connecting portion 312 and the second connecting member 32 can be improved through the hook-like structure 3121.

[0061] In the working state, at least one elastic connecting portion 312 is connected to a second connecting member 32 through the hook structure 3121, and can drive the sleeve structure 20 to move and thus drive the optical cable 40 to be installed to move, thereby completing the installation process of the optical cable 40 to be installed passing through the hook 11.

[0062] See also Figure 1 and Figure 2 In some embodiments, the second connecting member 32 includes a protrusion 321 , and the diameter of the protrusion 321 is smaller than the diameter of the hook 11 .

[0063] In the working state, at least one second connecting member 32 is engaged with a first connecting member 31 via the protrusion 321 .

[0064] In these embodiments, the optical cable threading device 100 provided in the embodiments of the present application is provided with a protrusion 321, the diameter of the protrusion 321 is smaller than the diameter of the hook 11, and the protrusion 321 can pass through the hook 11, that is, the entire structure of the second connecting member 32 can also pass through the hook 11. By providing the protrusion 321, the first connecting member 31 can be better connected with the second connecting member 32, and the reliability of the connection is better.

[0065] Please continue reading Figure 1 and Figure 2 In some embodiments, the protrusion 321 is coated with anti-slip rubber.

[0066] In these embodiments, the optical cable threading device 100 provided in the embodiments of the present application further enhances the reliability of the clamping connection between the protrusion 321 of the first connecting member 31 and the second connecting member 32 by coating the protrusion 321 with anti-slip rubber, thereby ensuring the reliability of the clamping connection between the first connecting member 31 and the second connecting member 32 when the sleeve structure 20 moves and the connecting assembly 30 does not pass through the hook 11.

[0067] Please continue reading Figure 1 and Figure 2In some embodiments, the sleeve structure 20 further includes a working section 21 and a preparatory section 22 . The preparatory section 22 is disposed on both sides of the working section 21 . The diameter of the preparatory section 22 gradually increases in a direction away from the working section 21 . The first connecting member 31 is fixedly connected to the working section 21 .

[0068] In these embodiments, the optical cable threading device 100 provided in the embodiment of the present application is provided with a working section 21, and the connecting components 30 are centrally arranged in the working section 21, and are arranged as centrally as possible to facilitate the operator to operate in the subsequent disassembly, replacement and maintenance work.

[0069] The first connector 31 is fixedly connected to the working section 21, while the second connector 32 may be disconnected from part of the first connector 31, so that part of the second connector 32 changes position and is not located in the working section 21. By providing the preparatory sections 22 on both sides of the working section 21, the preparatory sections 22 are in a bell-mouth shape, so that the sleeve structure 20 is conveniently sleeved on the supporting cable 10, so that the optical cable threading device 100 is conveniently sleeved on the optical cable 40 to be installed and the supporting cable 10, and can provide redundant accommodation space for the second connector 32 whose position has changed, so as to avoid part of the second connector 32 directly exceeding the setting working area of ​​the sleeve structure 20.

[0070] See also Figure 3 In some embodiments, the sleeve structure 20, the first connecting member 31 and the second connecting member 32 are all detachable structures. The sleeve structure 20 includes a detachably connected upper sleeve 23 and a lower sleeve 24, the first connecting member 31 includes a detachably connected upper first component 313 and a detachably connected lower first component 314, and the second connecting member 32 includes a detachably connected upper second component 322 and a detachably connected lower second component 323.

[0071] In these embodiments, the optical cable threading device 100 provided in the embodiments of the present application is provided with a detachable structure, which facilitates the storage of the optical cable threading device 100 when it is not in a working state. In the event that part of the optical cable threading device 100 fails or is damaged, the operator can directly replace part of the device, thereby facilitating the operator's operation during subsequent disassembly, replacement and maintenance work.

[0072] See also Figure 1 and Figure 2 In some embodiments, the optical cable threading device 100 further includes a pull rod 51 and a pull ring 50 , and the pull ring 50 is fixedly connected to the sleeve structure 20 .

[0073] In the working state, the wire drawing rod 51 is matched with the wire drawing ring 50 , and the wire drawing rod 51 pulls the sleeve structure 20 through the wire drawing ring 50 to drive the optical cable 40 to be installed.

[0074] In these embodiments, the optical cable threading device 100 provided in the embodiments of the present application allows an operator to pull the pull ring 50 through the pull rod 51 on the ground, thereby driving the sleeve structure 20 to move, and further driving the optical cable 40 to be installed to pass through the hook 11.

[0075] Optionally, two pull wire rings 50 are usually provided and respectively disposed on both sides of the sleeve structure 20 , so that the sleeve structure 20 can move in both directions.

[0076] Optionally, a hook-shaped device is provided at one end of the pull rod 51 to facilitate hooking the pull ring 50 . The operator operates the pull rod 51 to hook the pull ring 50 through the hook-shaped device, thereby driving the sleeve structure 20 to move.

[0077] Optionally, the pull rod 51 is a telescopic rod, which is convenient for storage when not in working state, and the length of the pull rod 51 can be easily adjusted to meet the working conditions of the optical cable 40 to be installed at different heights and different positions passing through the hook 11.

[0078] See also Figures 4 to 8 The embodiment of the present application will also describe in detail the working steps of the optical cable threading device 100 in the working state.

[0079] See also Figure 4 When the second connecting member 32 passes through the hook 11, the first connecting member 31 interferes with the hook 11, and the first connecting member 31 is pushed up by the outward thrust of the hook 11.

[0080] See also Figure 5 The first connecting member 31 is stretched open, and the first connecting member 31 is disconnected from the second connecting member 32. For the optical cable threading device 100 having only one connecting component 30, the working state is interrupted; the second connecting member 32 passes through the hook 11, so that the entire connecting component 30 passes through the hook 11.

[0081] See also Figure 6 After the first connecting member 31 is restored to its original state, it is reconnected with the second connecting member 32 that was originally matched. For this connecting assembly 30, the optical cable threading device 100 re-enters the working state. When the subsequent hook 11 is passed, the connecting assembly 30 will repeat the above Figures 4 to 6 process.

[0082] See also Figure 7 After the first connecting member 31 returns to its original state, it fails to restore the engagement relationship with the second connecting member 32 that was originally matched. For the optical cable threading device 100 having only one connecting component 30, the working state continues to be interrupted.

[0083] See also Figure 8, the next set of connecting components 30 passes through the hook 11, and the connecting components 30 will repeat Figures 4 to 6 The process, or connecting components 30 is repeated Figures 4 to 5 After the process, after the first connecting piece 31 in the next group returns to its original state, the first connecting piece 31 in the next group may not restore the snap-fitting relationship with the second connecting piece 32 in the next group, but restore the snap-fitting relationship with the second connecting piece 32 that is matched with the original first connecting piece 31.
