Problems solved by technology

The most commonly used method for derusting the surface of metal pipes is that workers use steel brushes, gauze (paper), etc. to repeatedly wipe rusty metal pipes. The disadvantages are high labor intensity, low work efficiency, and poor polishing effect; some use portable Grinding with electric grinding wheels, although compared with the previous ones, the labor intensity of workers is reduced and the work efficiency is improved, but the surface of the grinding wheel and the metal surface are in line contact. Sometimes in order to ensure the quality of grinding, grinding has to be repeated, and the overall work efficiency is relatively high Low
[0004] At the construction site, the anti-corrosion treatment of metal pipes adopts manual anti-corrosion paint. After the metal pipes are derusted, workers use brushes to paint the outside of the pipes. The strength and direction of each painting are different, resulting in uneven thickness of the paint. Some places are thick and some places are thin. At the same time, the paint has fluidity. In places where the paint is relatively thick, it will cause the paint to gather and even be in the shape of water droplets, which seriously affects the appearance and use.
Since the brush and the pipe are in partial contact, during the brushing process, the paint on other brushes that do not touch the pipe will drip to the ground, resulting in unnecessary waste of paint

Abstract

The invention relates to a semi-automatic portable derusting and paint spraying device for the surface of a metal tube, which comprises five parts, namely a movable hollow shaft system, a low-rotating speed transmission system, a derusting system, a cleaning system and a paint spraying system, wherein the movable hollow shaft system is used for fixing a metal tube on a central line of the movable hollow shaft system; the whole device moves forwards along a metal tube through the force applied on a handle; the circular motion of a motor self on the device is transferred to the derusting system, the cleaning system and the paint spraying system through the low-rotating speed transmission system, so that the derusting system, the cleaning system and the paint spraying system are driven to respectively carry out the circular motion around the metal tube, thereby performing procedures of derusting, cleaning and paint spraying on the metal tube; the whole device continuously moves forwards along the metal tube through the handle, and then the derusting and paint spraying work of the processed tube is finished.

Description

technical field [0001] The invention relates to a semi-automatic metal pipe surface derusting and painting technology, in particular to a fast and high-quality derusting and painting device. Background technique [0002] As we all know, iron-containing metal pipes will rust when stored for a long time. This is because the oxygen in the air dissolves in water and chemically reacts with iron to form a substance called iron oxide, which is more likely to absorb water. Accelerate the corrosion rate of pipelines, so metal pipes must be derusted and anti-corrosion treated before use. [0003] On the construction site, the rust removal and anti-corrosion treatment of metal pipes are usually two processes, which are treated separately. The most commonly used method for derusting the surface of metal pipes is that workers use steel brushes, gauze (paper), etc. to repeatedly wipe rusty metal pipes. The disadvantages are high labor intensity, low work efficiency, and poor polishing ef...
