INTRODUCTION ROPE DELIVERY APPARATUS FOR LAYING CABLE AND THE DELIVERY METHOD THEREOF}

      The present invention relates to an introduction wire delivery device for cable construction and a method for transmitting the same, and more particularly, an introduction wire installed in advance in a tube to pull a cable so that various cables can be constructed in a tube of a predetermined standard. The present invention relates to an introduction wire delivery device for cable construction and a delivery method thereof for efficiently transmitting internally.

      In general, various cables are installed at a predetermined place in order to provide electricity supply and communication facilities to various industrial facilities and large buildings.

      To this end, at the point where the cable is installed, the installation is performed by penetrating the corresponding cable inside the tube in a state in which a tube of a predetermined size is first installed. In this case, the cable can be easily installed in the tube. Inside the tube, a lead line made of rope is first installed.

      That is, the lead wire made of the rope is first sent from one end of the pipe to the other end, and then the cable is laid in the pipe by tying the cable to one end of the lead wire and pulling the other end of the lead wire. .

      On the other hand, in the delivery of the introduction line into the tube for the construction of the cable, conventionally injecting compressed air in a state in which the inlet of the tube is closed so that the introduction line is sent out into the tube, this method is to close the inlet of the tube In addition to the problem that requires a separate device and work to occur, the problem is difficult to send at the point where the pipe is bent in a curved form.

      In addition, it is difficult to control the delivery speed of the introduction line in the delivery of the introduction line by the above-described method, which causes the problem of breaking the tube while the tip of the introduction line hits the bent portion of the tube, and also at the outlet side of the tube. There is also a problem that a safety accident of workers waiting to be sent out of the introduction ship is concerned.

Accordingly, the present invention has been made in order to improve the conventional problems as described above, the object of which is to specify a lead line that is pre-installed inside the tube to pull the cable to be able to construct a variety of cables to a tube of a certain standard It is an object of the present invention to provide an introduction wire delivery device for cable construction and a delivery method thereof for efficiently installing a delivery device having a structure.

      An apparatus for transmitting a lead wire for cable construction according to the present invention for achieving the above object, in the apparatus for sending a lead wire in a pipe in which various cables are constructed, has a cylindrical body provided with a space therein; On the rear end side of the body, an air supply unit through which the compressed air is supplied through the compressor is formed to protrude in a tubular shape, and an introduction line inlet is formed at a predetermined point on the outer circumferential surface of the body to introduce an introduction line made of rope from the outside. The front end portion is characterized in that the lead line exit is formed is formed through which the rope introduced through the inlet line is discharged to the outside.

      Preferably, the front end side of the body is made of a conical shape of which the diameter decreases toward the tip, the outer peripheral surface of the conical shape is provided with a close contact member is in close contact with the inner peripheral surface of the pipe when the cable is installed when the delivery device is installed, The introduction line outlet is characterized in that the tubular protrusion formed on the pointed portion of the conical tip.
