Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiment is a part of the embodiments of the present invention, rather than whole embodiments.Based on this hair
Embodiment in bright, those of ordinary skill in the art's every other reality obtained without making creative work
Example is applied, all should belong to the scope of protection of the invention.
The present invention is applied to the connection method of OPGW optical cable tension stringing, including the grafting of optical cable twisted wire and steel pipe crimping, tool
Body implementation steps are as follows:
1, grafting pre-processes
As shown in Figure 1, being 6cm by a segment length, cross-sectional area 250mm2Steel pipe be inserted in old OPGW optical cable, and
The connector of new and old OPGW optical cable is scattered later in the position apart from end 1.5m for a in steel pipe center marking
Processing, makes optical cable twisted wire uniformly scatter and is rendered as umbrella；
2, optical cable grafting operates
As shown in Fig. 2, the new and old optical cable twisted wire to scatter to be b in grafting center marking, later will to root is inserted to
The optical cable twisted wire that grafting part exposes cuts several exposed twisted wires according to 20~40cm of interval at random, and by remaining strand
Line is adjacent to optical cable main line；
3, steel pipe crimping operation
As shown in figure 3, after the twisted wire grafting of new and old optical cable is completed, by the steel pipe movement being inserted in step 1 to grafting
The center at place makes that a is marked to be overlapped with b is marked, and will be embedded in later with the steel wire of twisted wire same material (doing sharpening processing in both ends)
In the gap of steel pipe and optical cable twisted wire, finally steel pipe is crimped using hydraulic device；
4, splicing position outer layer twisted wire is handled
As shown in figure 3, the optical cable twisted wire end cut in step 2, carries out segmentation binding with steel wire, makes new and old optical cable
Coupling part is rendered as " shuttle-type ", polish and wrapped up with plastic adhesive tape by exposed twisted wire the end of a thread later.
The twisted wire of new and old OPGW optical cable is carried out grafting by the present invention, and optical cable dragging is born using the frictional force between twisted wire
When pulling force, while crimping processing in splicing position is carried out using steel pipe, it is enough broken can to guarantee that new and old optical cable junction has
Disconnected pulling force, meets enough mechanical strengths, in addition, new and old optical cable junction of the invention is rendered as " shuttle-type ", can reduce more
It is sliding to can be avoided more line after polishing and adhesive tape wraps up for resistance when line coaster, new and old optical cable splicing position outer layer twisted wire the end of a thread
Vehicle causes to scratch to optical cable.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
