Abstract

PURPOSE:To shorten the working time on a passage by using a mechanical power and to lay an optical fiber cable to an extremely long length by once tentatively taking up the remaining cable on a drum and temporarily transferring this cable into a cable tank at the point of the laying tension limit in one direction from the intermediate part of a cable laying section. CONSTITUTION:The optical fiber cable 14 led out of the drum 21 is laid in the laying tension limit section in the direction A from a d manhole which is the intermediate part of the laying section. The cable 14 of the remaining A direction section is once taken up on the take-up drum 7. The cable 14 taken up on this drum 7 is set to the laying device consisting of a cable winding guide 1, the cable tank 2 and a shaft 15 for hanging a cable delivering device or the like and the cable 14 is housed into the cable tank 2. The pulling end thereof is then taken out. The pulling end of the cable 14 housed into the cable tank 2 is led out of the tank 2 and the cable of the laying tension limit section is laid in the remaining section of the direction A. The cable 14 of the remaining direction A is again taken up on the drum 7. The similar stage is thereafter repeated.

９割以上が布設稼働である。[Prior Art] Conventionally, when installing optical fiber cables, logs for towing are towed by a towing machine with a maximum pulling tension of 200 kgI. Even when installing long lengths, use an intermediate separator.
There was a method in which H cables were piled up in a large 80-figure shape on the road by human labor, and then the cables were reversed and the tensioned ends were taken out and laid (Special Publication No. 36444/1983). There is a limit to how these can be piled up in a large figure-eight shape on roads, making it difficult to install them in extremely long lengths. In addition, more than 90% of optical fiber cable construction is in operation.

The cable beyond that point is wound around the -H drum using mechanical force, and in order to take out the cable pulling end at the beginning of the drum winding, mechanical force is used to take out the cable pulling end at the beginning of the drum winding in order to lay the cable beyond that point. Then the cable is laid to the next cable traction tension limit point and further laid in the manner described above.

はない。The cable winding drum driving ring gear 6 and the cable winding drum driving hydraulic motor 5 are connected in parallel with the drive motor of the sub-sending device 18 by free I/I':. The cable 14 is pushed into the inner wall of the tank 12 by the drive motor of the 7" cable sender 3. Since the sub sender 18 is wound at an angle of υ1200 from the tip of the id 1, the tension of the optical fiber cable 14 is reduced. Due to the unique action, the cable 14 does not bend.

を開始する。Therefore, the winding guide 1 automatically rotates in the direction opposite to the direction in which the cable is fed. Furthermore, by increasing the speed of the cable sender 3 and the sub sender 18, the tip of the sub sender 18 winds and accumulates the cable 14 toward the wall of the tank 2 by applying centrifugal force. Also, the winding guide is gradually accumulated inward by the expansion/contraction adjustment adjustment ring I3. Furthermore, cable 1
4 is stored in a long length in the table tank 2, by rotating the winding guide position adjustment handle 9, the winding guide position adjustment handle 9 is rotated, and the winding guide position adjustment handle 9 is wound around the cassost stand drum 10 with a worm and its drum Iθ, which are directly connected to the handle 9. position adjustment wire 8
By using this in combination, the winding 1 and the guide 1 are sequentially raised and lowered together with the suspension shaft 15 of the sicouble feeder. Also cable tank 2
If the storage is not completed in the reserve tank 2', the storage starts continuously in the reserve tank 2'.
