Pipeline wall spray-coating device

Abstract

The invention relates to a pipeline wall spray-coating device which comprises a disc, a tripod, a rotating ring and a spraying pipe. One end of the disc is fixed to the tripod. Movable wheels are fixedly installed on the tripod. An inclined rod is fixedly installed between the tripod and the disc. The rotating ring is arranged at the center of the disc. One end of the rotating ring is connected with a bead on the inner wall of the disc through a movable groove. A clamping shell connected with the rotating ring is arranged outside the bead. The other end of the rotating ring is connected with aspraying pipe fixed to a cover plate through an extension rod. One end of the spraying pipe penetrates through the extension rod and is connected with a material pipe in the rotating ring. The otherside of the other end of the spraying pipe is placed on a protection jacket. A paint sensing device connected with the outside world through a liquid level sensor is arranged on the material pipe. Theoutput end of the paint sensing device is connected with a programmable controller. The pipeline wall spray-coating device has the advantages of being high in intelligent degree, capable of liberating the labor force, capable of conducting automatic spray-coating operations through program control according to pipelines with different apertures, and good in promotion performance.

Description

technical field [0001] The invention relates to the technical field of pipeline spraying devices, in particular to pipeline wall spraying equipment. Background technique [0002] Spraying is a coating method in which spray guns or disc atomizers are dispersed into uniform and fine droplets by means of pressure or centrifugal force and applied to the surface of the object to be coated. It can be divided into air spraying, airless spraying, electrostatic spraying and various derived methods of the above basic spraying forms, such as large flow and low pressure atomization spraying, thermal spraying, automatic spraying, multi-group spraying, etc. [0003] Pipeline wall spraying equipment is mainly used for automatic spraying of the inner wall of the pipeline, and spraying and anticorrosion work on it. For large pipelines, it is inconvenient to spray manually, and it is labor-intensive to use. The current pipeline wall spraying The equipment also needs manual assistance when sp...

Problems solved by technology

[0003] Pipeline wall spraying equipment is mainly used for automatic spraying of the inner wall of the pipeline, and spraying and anticorrosion work on it. For large pipelines, it is inconvenient to spray manually, and it is labor-intensive to use. The current pipeline wall spraying The equipment also needs manual assistance when spraying automatically. The degree of intelligence is not high, and the flexibility of the equipment cannot be adjusted according to the pipes of different sizes. The paint on the inner wall of the pipe will also be sprayed unevenly, which reduces the work efficiency.
