Description

Sweeping Apparatus for outer plate of hull}

The present invention relates to a sweeping device, and more particularly to a hull shell sweeping device.

Sweeping is a pretreatment that takes place before final painting on the hull shell during the ship's construction. The sweeping operation is carried out to remove foreign substances attached to the hull shell and to scratch the paint surface of the hull shell to strengthen the adhesion of the paint.

Sweeping operations are typically performed manually by drivers and operators aboard an elevated vehicle platform. In other words, when the driver approaches the high-altitude platform to the hull shell, the accompanying worker removes the foreign matter, etc. of the hull shell using a grinding paper or hand mop.

The work method as described above reduces work efficiency and lowers productivity. In addition, there is a high risk of safety accidents as drivers and workers ride on narrow platform platforms.

An object of the present invention is to provide a hull shell sweeping device which facilitates the sweeping operation of the hull shell.

One aspect of the present invention is a fixing portion, a support portion, one end of which is rotatably fastened to the fixing portion, a work portion that is rotatably fastened to the other end of the support portion to sweep the outer plate of the hull, and one end of the fixing portion. It is fastened, and the other end is fastened to one side of the support to provide a hull shell sweeping device comprising a first operating arm for rotating the support.

Embodiments of the present invention can easily remove the foreign matter and the like attached to the hull shell. In addition, there is no need for a driver and a worker to ride on the platform, thereby preventing a safety accident.
