rope penetration device for setting optical fiber cable

摘要

The present invention relates to an optical cable laying rope tether through the rope for installing the optical cable using compressed air on the communication line embedded between the manhole and the manhole, the diameter of the communication line to pass through the rope Regardless of the pressure, the communication line can be routed with little force, and the pressure from the compressed air can be transmitted to the tip of the rope.;To this end, a locking member 12 having a locking groove 12a at one end thereof is coupled, and a sleeve 11 having recessed grooves 11a formed at both sides thereof, a slider 13 removably coupled along the sleeve, A rotation lever 14 rotatably installed in the recessed groove of the sleeve to move the slider forward and backward; a packing 15 coupled to the slider to expand as the slider is moved and closely connected to the communication pipe 3; A rope rope guide port 7 composed of an expansion control member 16 for adjusting the expansion amount of the slider; A connecting member 17 fitted into the locking member, coupled to the locking member, a locking lever 18 rotatably installed at the connecting member, and fixed to one end of the connecting member, the communication lever being fixed to one end of the connecting member. An air supply block 21 having a plurality of air injection holes 20 inclined toward the side, a connector 22 fixed to the air supply block to guide compressed air supplied from the air compressor 8 to the air injection holes, It is fixed to one side of the air supply block, the rope rope inlet 23 is formed in the inlet side of the water droplet-shaped insertion hole 23a passing through the rope rope, and is rotatably coupled to the rope rope inlet block, rope rope An air duct tool 9 composed of a rope rope knot passing block 24 having an insertion hole 24a having the same shape as the insertion hole formed in the inlet block; It is composed of a rope string 6, which is bundled with a plastic bundle 10 that is closely connected to the inner peripheral surface of the communication line (3) at the tip.
