Description

Painting equipment for ships {painting equipment for ships}

The present invention relates to a painting apparatus for a ship, and more particularly, to a painting apparatus for a ship that travels and processes a deck of a ship.

In general, in the shipbuilding industry, painting of a ship deck results in different coating thicknesses depending on working conditions such as a distance from an object to be coated, a spray speed, and a spray pressure of a nozzle. This has a significant effect on the workability of skilled and unskilled people, and causes not only an increase in the amount of paint used but also a decrease in productivity due to the non-uniform coating quality and thickness.

Since the worker directly performs the painting work on the ship deck by hand using a pole gun, there is a problem in that the painting quality is deteriorated and the worker's musculoskeletal disorder is caused by the long-term downward work. Therefore, development of an automated device capable of replacing manual work is being made.

In performing the painting process of large structures such as ships and aircraft, robots that can move inside large structures or blocks, avoid obstacles such as auxiliary structures inside, and pass through halls, which are moving passages between areas, are used. By using a robot to perform the painting process in place of the worker in a poor working environment, it is possible to guarantee the safety of the worker and to obtain a uniform painting quality. A robot has been proposed, but it is configured somewhat complicatedly, and it is difficult to perform the painting work of the deck in detail.
