Description

Polishing equipment for ships{AN APPARATUS FOR POLISHING OF SHIP}

The present invention relates to a polishing apparatus for a ship, and more particularly, to a polishing apparatus for a ship capable of performing a polishing operation on the painted surface of the hull while traveling while attached to the outer surface of the hull.

In general, ship construction is completed through an assembly process in which a number of blocks constituting a hull are manufactured by dividing it into a number of unit blocks, and a plurality of blocks that have been manufactured are painted and then connected to each other.

At this time, even after the ship is assembled and the finish painting is applied, it takes a long time to complete the work inside the hull, so the painted surface of the hull exterior may be exposed to the outside for a long period of time, which may be affected by the external environment.

In addition, even if it takes a long time to deliver the built ship to the owner, the painted surface of the hull exterior may be exposed to the outside for a long time.

That is, if the outer surface of the painted hull is exposed to the outside for a long period of time, contamination may occur on the painted surface of the hull due to external environments such as rainwater, and accordingly, conventionally, grinding the contaminated painted surface before delivery of the built ship. It was removed and repainting was carried out.

However, in this case, there arises a problem that additional labor and paint costs required for grinding and painting work are consumed.

Therefore, recently, in order to prevent contamination of the outer surface of the hull, peelable coating paint has been applied to the painted surface, but the product cost is high and sometimes the coating paint does not come off. There is a problem with difficulties.
