Abstract

The invention relates to the technical field of pipe spraying anti-corrosion conveying, and provides large construction pipeline inner wall spraying conveying equipment. The equipment comprises a conveying line, a hanging rail is arranged over the conveying line in parallel, and a moving trolley is arranged on the hanging rail. A spraying box is hung below the moving trolley; and a sleeve assemblycapable of horizontally stretching and retracting is arranged at one side of the spraying box. When the spraying box moves to the position above a pipe body, the spraying box descends, and the movingtrolley and the pipe body move at the same speed; the sleeve assembly extends out, and a nozzle enters an inner cavity of the pipe body; and in the extending process, the nozzle sprays paint to the inner wall of the pipe body, and a coating is formed on the inner wall along with rotation of the pipe body. Therefore, the movable spraying box is arranged above the conveying line, and the nozzle isarranged on the telescopic sleeve assembly, so that spraying of the inner wall of the pipe body is realized in the conveying process; and an offline spraying procedure and equipment are avoided, so that the production cost is greatly reduced, and the production efficiency is remarkably improved.

Description

technical field

[0001] The invention belongs to the technical field of pipe spraying and anticorrosion transportation, and in particular relates to a large-scale construction pipeline inner wall spraying and transportation equipment. Background technique

[0002] With the development of China's economy, the scale of infrastructure construction is getting bigger and bigger. The laying of the municipal pipe network is one of the links.

[0003] The pipelines used in construction need to be buried underground for a long time, so the anticorrosion of pipelines is the key to ensure the service life. Since the construction pipelines are mostly large steel pipes, special equipment is usually required for anti-corrosion operations during production, resulting in high production costs and low production efficiency.

[0004] The Chinese patent application number 202010126157.4 discloses a plastic layer winding and forming device for socket tubes, which can realize the anticorrosion ...
