Description

Technical Field

[0001] This utility model belongs to the technical field of pipeline spraying devices, and in particular relates to an automatic pipeline walking and rotating spraying robot. Background Technology

[0002] In the pipeline construction and maintenance process, it is crucial to apply a comprehensive and uniform protective coating to the inner and outer walls of the pipeline.

Existing equipment has room for improvement in terms of painting effect and adaptability to pipes of different sizes. Therefore, there is an urgent need for a robot that can flexibly adapt to different pipe diameters, rotate efficiently, and achieve all-around painting. Utility Model Content
