Shelling-out and coating device

Abstract

The invention belongs to the field of shelling-out, coating and corrosion prevention, and particularly provides a shelling-out and coating device which comprises a brush holder cover, a brush holder, a brush head base, an elastic pipe, a push button and a push-press piece. The brush holder cover and the brush head base are connected to the two ends of the brush holder respectively. A storage cavity is formed in the brush head base. A top plate of the brush head base is evenly provided with a plurality of brush hairs and is provided with a plurality of paint outlet holes communicated with the storage cavity respectively. The elastic pipe is located in the brush holder, one end of the brush holder is inserted into the storage cavity and is connected with the top plate, the other end of the brush holder is a free end, and one end of the elastic pipe is evenly provided with a plurality of discharge holes in the circumferential direction. The push button capable of vertically moving and being pushed inwards is arranged on the brush holder, and the push-press piece is arranged on the push button, wherein the push-press piece is used for pushing and pressing the elastic pipe and pushing and pressing the paint in the storage cavity out of the paint outlet holes. The shelling-out and coating device is flexible to assemble, easy and convenient to operate, safe and reliable to use, capable of saving raw materials, and free of polluting the environment.

Problems solved by technology

[0002] From our living places, environment, daily necessities, to cross-sea (river, river) bridges, marine engineering, coastal engineering, petrochemical, electric field and power frames and other steel structures, especially the interconnection of various structures (such as connection plates, rivets, bolts, nuts), joint gaps, edges, corners, uneven surfaces, easy to accumulate water, moisture, salt and other corrosive media; especially in the sea, the coastal areas of the gulf are strongly affected by salt and humidity, exposed Corrosion of steel structures and connecting components develops rapidly. Initially rusting, rust liquid damages the appearance. If the corrosion deepens, the strength of connecting components and structures will decrease further, so that the connection will fail, affect production safety, and seriously cause accidents. Therefore, it must be done in advance. Perform maintenance

In the past coating protection methods, firstly, it was difficult to coat the uneven surfaces and sharp parts and edges such as joint gaps, edges, and corners with sufficient coating, and even the downward facing parts were not only difficult to carry out Brushing, and it is easy to paint flying, flowing (or sagging), missing coating, etc.; second, the paint contained in the brushing tool is very limited at one time, so the brushing area at one time is very limited, and it is easy to drip and paint flying, polluting surroundings

In addition, most bridges (especially cross-sea and river-crossing bridges), power racks and other high-altitude operations have harsh and dangerous operating environments on the construction site, so the simplicity and safety and reliability of operations must be improved.
