Based on the principle, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention.

In the present invention, the underground cable (4) is inserted into the cable network 40, the horizontal roller body 30 is installed from the outside to support the cable network 40, the horizontal roller body 30 is an inclined roller It is connected to the radial fixing body 10 by the sieve 20 and connected to the lead cable 5 by the rotating bracket 14, the roller 28 to the inclined roller body 20 and the horizontal roller body 30 ( 38) is formed to eliminate the friction with the inner wall of the underground pipe (50) is the main configuration.

The radial fixing body 10 protrudes radially around the circular body, and a fixing protrusion 12 is formed, and a bolt hole 11 is formed at the center thereof and fixed to the rotary bracket 14 by the fixing bolt 13. The rotary bracket 14 prevents twisting of the lead cable 5 even if the radial fixture 10 rotates. The rotary bracket 14 is connected to the withdrawal cable 5 connected to the winch and installs the underground cable 4 to the other manhole through the underground pipe 50 by the force of the winch.

The inclined roller body 20 is fixed by the roller pin 29 and the snap ring 29-1 so that the roller 28 protrudes to one side between the two roller fixing plates 21, and one end of the roller fixing plate 21 is fixed. In the fixing hole 22 is formed is fixed to the fixing hole and the fixing pin 24 formed in the fixing projections 12 of the radial fixing body 10 to be rotatable. A ring groove (not shown) is formed in the fixing pin 24 so that the snap ring 26 is fitted into the fixing pin 24.

The fixing hole 23 formed at the other end of the roller fixing plate 21 is rotatably fixed to the fixing hole and the fixing pin 25 formed at the connecting end 33 of the horizontal roller body 30. At this time, a ring groove (not shown) is formed in the fixing pin 25 so that the snap ring 27 is fitted and fixed.

The horizontal roller body 30 is formed by forming an intermediate connecting portion 32 between a plurality of roller fixing parts 31, in which the roller 38 protrudes to one side and is fixed by the roller pin 39 and the snap ring 39-1. .

A cable mesh catching groove 35 is formed at an end opposite to the roller 38 of the intermediate connector 32, and a catching jaw 36 is formed in the cable catching groove 35 to prevent the cable network 40 from being separated. . The crossing portion 41 of the cable network 40 is inserted into and secured to the cable mesh locking groove 35, and an insertion hole 37 for inserting the crossing portion 41 is formed next to the locking projection 36.
