In general, the installation of cables (power lines) is to install cables in underground pipelines installed between bases or between substations and power consumers to build a power grid.

A widely used method for installing such a cable is to physically press the cable to install the cable in the buried channel. However, in such a method, due to the nature of the power line, the cable may be damaged due to the physical force applied when pulling the cable, so that the installation distance is limited. Therefore, the manhole should be installed at a predetermined distance (typically about 350 m) There is a problem in costs such as an increase in construction cost and maintenance and repair of a manhole, and a technique capable of embedding a long-distance cable is required.

In order to embed the above long-distance cable, it is necessary to know the technology about the cable carring method for installing a new type of long-distance cable which can increase the cable installation distance by effectively attenuating the physical force applied to the cable when the cable is laid The applicant of the present application discloses the technique of Korean Patent No. 10-1071562 entitled " Long-distance cable installation method ".

FIG. 1 is a view for explaining a conventional cable carrying device for installing a long-distance cable, and FIG. 2 is a perspective view of a cable-carrying device for installing a long-distance cable.

Referring to FIG. 1, a duct parameter value affecting a cable installation operation is inspected before a cable 9 such as a power line is installed in a buried pipe 1 installed in an underground, and the buried pipe 1 is connected to a cable car The cable carrying device 10 for long cable laying allows the carrier 30 on which the cable 9 is placed to be secured to the rope 20 and the rope 20 to be pulled The pulling force of the equipment 100 acts to cause the cable 9 to be transferred from the start hole manhole 2 to the reaching manhole 3 so that damage is caused due to pulling like a power line when a cable is installed between two relatively long distances The cable 9 can be stably embedded.

Referring to FIG. 2, a stopper 28 is fixedly mounted on the rope to support the carrier 30 to fix the position, thereby causing traction on the carrier 30 and the cable 9.

However, conventionally, there has been a disadvantage that a clip for transmitting a tensile force to a cable when the cable is installed is fixed to the rope, so that an expensive cable can not be recovered and must be installed like a power cable.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 1, the present invention includes a rope 20 installed in a buried pipe between a start manhole 2 and a reaching manhole 3, A carrier 30 having a first channel 36 to which the cable is coupled and a second channel 38 through which the rope 20 is passed and a rope 20 mounted on the rope 20, (Not shown) for transmitting the pulling force of the cable to the carrier 30 and a pulling machine 100 installed at the reaching manhole and connected to the rope 20 for pulling the cable into the buried channel The present invention is characterized in that the clip is formed into a wedge shape so as to be able to transmit a tensile force to the carrier and be detached from the rope.

3 is a perspective view of a pulling rope retracting clip of a long-distance cable carry device according to an embodiment of the present invention, and Fig. 4 is a perspective view of a pulling rope retracting clip of a long-distance cable carry device.

3 and 4, the clip 40 is provided on the rope 20 and is in contact with the carrier 30 during pulling to transmit a traction force to move a cable fixed to the carrier. And a collecting unit 44. [0050]

The locking jaw 42 is formed in an annular shape and has an inner diameter that is larger than the outer diameter of the rope 20 so that the rope passes through and the outer diameter is relatively greater than the inner diameter of the second channel 38 of the carrier 30 And is tightly attached to one surface of the carrier 30 when pulling the rope, so that the pulling force applied to the rope is transmitted to pull the carrier 30.

The wedge portion 44 is formed so as to have a reduced inner diameter as it goes from one end portion to the other end portion of the engaging shoulder portion 42 so that the frictional force increases toward the one end portion of the rope 20 inside the return portion 44 .

Therefore, when the rope is pulled to one side, it can be pressed and connected to the rope, and can be separated from the rope when pulling the rope to the other side.

In detail, the collecting unit 44 is formed of a plurality of unit wedges along the circumferential direction. In the present invention, the collecting part 44 is cut into two parts in an upward and downward direction, and a plurality of parts can be provided so as to be able to transmit an appropriate tensile force according to the use environment and the state of the carrier.

The recovering portion 44 is provided with a reinforcing portion 46 protruding from the outer circumferential surface of the end portion to reinforce the strength of the end portion of the collecting portion 44. The reason for reinforcing the end portion of the collecting portion 44 is that it is inserted into the second channel of the carrier 30 and is inserted therein.

And is formed to have a semicircular shape on each of the unit wedges since it protrudes along the outer circumferential surface of the end portion of the collecting portion 44.

The outer circumferential surface of the return portion 44 may be inclined toward the one side so that it can be inserted into the second channel inner diameter of the carrier 30. The pulling portion 44 of the clip 40, The clip 40 and the carrier 30 are tightly inserted into the second channel inner diameter of the carrier 30 so that the pulling force can be stably transmitted.
