Abstract

The invention relates to the technical field of pipeline spraying robot, in particular to a pipeline inner wall spraying robot adaptive to a pipe diameter. The robot specifically comprises a main frame body, a moving mechanism and a spraying mechanism, and the main frame body serves as a fixing base, and is of a frame structure overall; the moving mechanism is fixed to the outer side face of the main frame body, and used for driving the robot to move in the radial direction or axial direction of a pipeline; the spraying mechanism is arranged on the main frame body, and moved with the main frame body; the moving mechanism comprises a variable diameter device and a driving wheel component, and the variable diameter device is arranged on the outer side face of the main frame body, and used for regulating the extension distance of the driving wheel component; and the driving wheel component is installed on the outer side face of the main frame body through the variable diameter device, andused for driving the robot to run. The pipeline inner wall spraying robot can adapt to pipelines in different pipe diameters, and runs along the inner wall of the pipeline steadily; the pipeline inner wall spraying robot has the advantages of uniform spraying, high adaptability, relatively high spraying efficiency and the simple structure, and can be applied to spraying operation of various pipelines.

Description

technical field

[0001] The invention relates to the technical field of pipeline spraying robots, and more particularly relates to a pipeline inner wall spraying robot with self-adaptive pipe diameter. Background technique

[0002] As an important means of transportation of marine resources, pipelines play an important role in the core industries of the national economy such as natural gas, nuclear industry, petroleum, etc. In order to enhance the corrosion resistance of pipelines, researchers have developed coatings and corrosion inhibitors to coat the surface of materials to reduce pipeline corrosion. In spraying applications, manual and simple nozzles are often used for spraying. In long-distance pipelines In spraying, manual spraying is difficult and the spraying time is long. Therefore, the research and development of the robot for spraying the inner wall of the pipeline is of great significance. At present, there are some robots on the market that can solve pipe sprayi...
