A painting device for the outer wall of a water conservancy pipeline

Abstract

The invention discloses a paint brushing device for the outer wall of a water conservancy pipeline. The paint brushing device comprises a base, an upper clamping block, a lower clamping block and fixing devices. A screw rod is further rotatably mounted on the inner sides of the upper portions of a left side plate and a right side plate, a screw sleeve is connected to the screw rod in a threaded mode, and the upper portion of the screw sleeve is slidably connected with a top plate; the upper clamping block is fixedly mounted at the bottom of the screw sleeve, the lower clamping block is fixedlymounted at the telescopic end of a first electric push rod, and the upper clamping block and the lower clamping block are of the same semicircular ring structure; and liquid storage cavities are formed inside the upper clamping block and the lower clamping block, a plurality of paint brushing rollers are rotatably mounted on the inner side of each of the upper clamping block and the lower clamping block, and a plurality of paint spraying heads are further rotatably mounted on the inner side of each of the upper clamping block and the lower clamping block. The upper clamping block of the semicircular ring structure and the lower clamping block of the semicircular ring structure are spliced into a complete circular ring, therefore, the paint spraying heads on the inner side of the circularring spray paint to the pipeline, and paint brushing is conducted through the paint brushing rollers, so that paint brushing is more uniform, the pipeline paint brushing efficiency is improved, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to the technical field of pipeline painting, in particular to a painting device for the outer wall of a water conservancy pipeline. Background technique [0002] The word water conservancy was first seen in the chapter "Filial Piety and Caution for People" in "Lu Shi Chunqiu" published at the end of the Warring States period, but the "water conservancy" it mentioned refers to the benefit of fishing. From about 104 BC to 91 BC, Sima Qian, a historian of the Western Han Dynasty, wrote "Historical Records", among which "Hequshu" (see "Historical Records·Hequshu") is China's first general history of water conservancy. After describing a series of historical facts of river control and flood control, canal opening and navigation, and water diversion and irrigation during the historical period from Yu's water control to the Yellow River Huzi blockage by Emperor Wu of the Han Dynasty, the book sighed: "Water is a good or bad thing", and p...

AI Technical Summary

Problems solved by technology

[0003] Water conservancy irrigation usually uses pipelines. Corrosion of pipelines and how to prevent corrosion are one of the important links in pipeline maintenance. At present, the anticorrosion of oil pipelines is mainly carried out by manual painting. Large, low work efficiency, and manual painting is prone to loopholes, uneven painting, and poor painting quality
