Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable installation apparatus,

The present invention relates to a cable laying apparatus operating system and a method of operating the same, and more particularly, to a cable laying apparatus operating system and a method of operating the cable laying apparatus, which optimize a tension specification and a laying method of an installation device for towing at a front end and a middle of a cable to be installed.

In general, one of the reasons for the difficulty in installing cables during a large labor-intensive shipbuilding process is the resistance due to the friction between the trays and the cables, which requires a lot of labor to install the wires.

For example, various supporting objects such as cables or tubes and electric wires are installed for power supply and connection between devices during ship drying. These wires are installed in a multi-stage cable tray and are fixed to the ship. They are various kinds and sizes, and more than one million meters are installed depending on the ship type.

In addition to the large number of workers, many workers are working in the cable installation, and the work conditions are very poor due to the narrow working space and the high and deep converters, which lowers productivity. Above all, the worker's musculoskeletal diseases are rapidly increasing .

On the other hand, in order to solve this problem, based on the formula for calculating the tension of the cable to be installed, the specification of the winch is determined by calculating the pulling force required when the winch is pulled at the end of the cable. It is also used to determine cable specifications by calculating the tension of the cable that can withstand the pulling of the cable.

For example, as shown in FIG. 1, in order to install the power cable 10 through the pipeline 7, an operator directly enters the straight hole 6 through a manhole to perform work, The controller 1 for installing the caterpillar 2 and the cable drum 3 in consideration of the radius of curvature and the bent portion in the vertical hole 6 and for controlling the operation is installed. Thereafter, the pull rope (4) is used to connect the pull rope (5) in the pipeline (7) and the power cable (10), and the power cable (10) is installed. At this time, in the case where there is a portion where the power cable 10 is refracted in the right-angle opening 6, the radius of curvature of the power cable 100 is considered.

In addition, such an underground laying method is carried out by letting the cable which is caught in the cable drum to be released by the caterpillar device while pulling the cable with the winch on the opposite side. Or a cable-laying type feeder is installed at the cable start-stop to assist in cable feeding. However, the feeding device is slippery if there is a load on the cable that exceeds its pulling force.

One example of the technique for solving such a problem is described in Documents 1 and 2 below.

For example, Patent Document 1 discloses a connector having a first connector coupled with a first cable drawn in from a first direction, a second connector coupled with a second cable drawn in from a second direction, And a bent portion electrically connected to the first connecting portion and the second connecting portion to electrically and mechanically connect the first cable and the second cable, the first connecting portion and the second connecting portion of the bent portion being formed to have a specific angle, And the first cable and the second cable are laid out in accordance with a specific angle of the bent portion.

Patent Document 2 discloses a technique in which a cable wound around a large hub on the ground is supplied into an electric power source by a laying scaffold and a cable in a power source is fixed The cable is transported along the guide roller while being drawn by the caterpillar and mounted on the fixed caterpillar while the cable is seated on the guide roller and the cable is transported along the guide roller by the pulling of the plurality of caterpillars, And a guide roller for laying on a hanger installed.

Korean Patent Laid-Open Publication No. 2013-0014108 (published on Mar. 02, 2013) Korean Registered Utility Model No. 20-0263315 (Registered on Mar. 23, 2002)

However, in the conventional technique as described above, the tension required when the cable is pulled at the first end of the cable is calculated in order to calculate the tension of the installation device installed at the end or to determine the tension specification of the cable. That is, in the conventional technique, the tension applied to the cable end is calculated to determine the specifications of the winch and the specifications of the cable. However, the method of turning off the cable at the end of the cable is such that when the curved portion or the curved portion inside the cable is large, the interference of the cable becomes large and the traction at the end is impossible in most cases.

In order to solve this problem, in the technique disclosed in Patent Document 1, the bent portion is set to a specific angle, but in such a case, the installation cost increases.

Then release the cable with the cable drum and main feeder (push type) on the deck of the hull and push. When the cable reaches the installation device 110 installed on the tray, the operator hooks the cable with the gripper and pulls the cable through the reciprocating operation. Such an installation device 110 can be controlled by a terminal of an operator installed at a cable start and stop.

Next, when the individual On / Off switch of the installation device 110 is turned off, the switch is turned on to operate the installation device 110 (S40).

In such a progressing stage, the worker 3 proceeds while guiding the cable end to the rope. Each worker also tightens the gripper when the guided cable comes near the laying device 110. [ That is, the present invention applies a structure for fastening the gripper during cable transportation. After the gripper is fastened as described above, the individual ON / OFF switch of the placement device 110, which is responsible for the gripper, is turned on.
