Description

Head detachable blasting device {Head detachable blasting device}

The present invention relates to a blasting device for blasting, which is one of the pretreatment processes for painting the outer plate of a hull. As the body and head are moved along the shell of the hull, blasting can be performed in various postures such as downward, upward, and side views, so both flat and curved surfaces can be smoothly performed and the head can be separated from the body. It is a head separation type blasting device that can use the head or body for separate work.

In general, the blasting operation sprays abrasives such as iron powder at high pressure through a nozzle before painting the outer plate of the hull to remove foreign substances or rust attached to the outer plate and to make fine grooves on the surface so that the paint can adhere well to the steel plate. As a process, it is always necessary when building or repairing a ship.

This blasting operation is usually performed using a blasting device, and as a prior art related to the blasting device, there is a blasting device proposed in Patent Registration No. 10-1057548.

The above patent includes a blasting unit that performs a blasting process while traveling in close contact with the surface to be coated by vacuum pressure; an electromagnet unit attaching the blasting unit to the surface to be painted; A sensing unit for measuring the vacuum pressure inside the blasting unit; and a control unit configured to control magnetic force of the electromagnet unit based on the measured vacuum pressure value, wherein the control unit magnetizes the electromagnet unit when the measured vacuum pressure value is less than or equal to a preset reference value. A characterized blasting device has been proposed, and is configured to selectively magnetize the electromagnet unit only when the adhesion between the surface to be painted and the blasting unit is reduced, but when the adhesion between the surface to be painted and the blasting unit is momentarily decreased, the electromagnet unit There is a risk that the blasting unit may fall from the surface to be painted because the driving is not smooth, and when the magnetic force of the electromagnet unit is relatively high, the moving speed of the blasting unit may be slowed down or the power required for moving may be rapidly increased.

As another prior art, there is a blasting device proposed in Patent Registration No. 10-1885281.

The patent includes a frame portion fixed to a work surface; a work head unit performing a blasting operation on the work surface; a holder for supporting the work head; a first movement unit for moving the work head in the forward and backward directions with respect to the work surface; and a second moving unit for moving the working head in a vertical direction with respect to the working surface, wherein the first moving unit includes: a first guide unit for guiding movement of the working head in a forward and backward direction; a first moving block connected to the holder and moved in the forward and backward directions while being guided by the first guide; And a blasting device including a first operation unit for moving the first moving block in the forward and backward directions has been proposed. The amount of vertical movement of the work head is small, so it is difficult to blast a relatively large area, so the work speed is inevitably slow. In the case of non-curved surfaces, the work is impossible.
