BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable hanger device, and more particularly to a cable hanger device that can be conveniently used when welding work in several places in a predetermined area.

In general, during the construction of large ships, the ship to be built is divided into several blocks and built. At this time, each block is manufactured in a block assembly factory, the finished blocks are combined with each other in the dock (dock) is to dry one shelf. Such ship construction requires a lot of welding work. In particular, the block manufacturing operation requires a lot of welding process.

In such a block manufacturing operation, each block is divided into several compartments, and partitions are installed between each compartment. Accordingly, in order to perform welding work in several compartments at the same time, every welding device required for welding work and a cable capable of supplying power, gas, etc. must be supplied to each section to be welded.

Conventionally, a welding worker manually moves a cable required for welding, or uses a very simple cable hanger fixed at a certain height. Needless to say, the welding cable is manually moved by the worker, but it was very inconvenient when a fixed cable hanger of a certain height was used to supply the welding cable to the welding place. For example, in the conventional fixed hanger device, since the height of the hanger cannot be adjusted according to the height of the block, the height of the block to be manufactured is restricted, and the cable is stretched longer than necessary. This eventually leads to strain on the cable and becomes very difficult when moving to the welder or the required location. In addition, after completing the work of one compartment, when moving to a neighboring area, it is inevitable that the cable must be moved to a long distance by manpower. In this case, the worker becomes tired easily and is likely to be damaged by slag or the like generated during the cable or the cutting operation. In addition, several cables are entangled with each other, which may cause a safety accident.
