Magnetic memory detection robot for buried pipeline

Abstract

The invention provides a magnetic memory detection robot for a buried pipeline in order to solve the problem that an existing robot can only detect the formed macro defects and is prone to being stuckand blocked. The magnetic memory detection robot is characterized in that the magnetic memory detection robot comprises a robot main structure, a foldable third-foot stabilizing system, a variable-angle track crawling system, an adaptive variable-diameter magnetic memory detection system and a double-X-shaped multi-spring suspension system; the foldable third-foot stabilizing system is used for maintaining the stability of the robot during advancing in a pipeline and adapting to the working conditions of the variable-diameter pipeline; the variable-angle track crawling system is used for realizing close contact between a crawling mechanism and the inner pipe wall; the adaptive variable-diameter magnetic memory detection system is used for realizing the magnetic memory detection function of a sensor for different pipe diameters; and the double-X-shaped multi-spring suspension system is used for adjusting the height of the robot and ensuring that the center of the magnetic memory detection system coincides with the center of the pipeline. The magnetic memory detection robot can carry out full-life and all-round magnetic memory detection on early stress concentration, hidden damage and macro defects of the pipeline.

Description

technical field [0001] The invention relates to a magnetic memory detection device in buried pipelines, in particular to a magnetic memory detection robot for buried pipelines. Background technique [0002] The petroleum energy industry has an important strategic position in the national economy. With the continuous development of my country's economy, the demand for oil and gas resources has increased sharply, and it has changed from an oil exporter to a pure oil importer, driving the development of the oil transportation industry. Oil and gas pipeline transportation has become the preferred transportation method for crude oil, refined oil and natural gas due to its advantages of large transportation volume, good airtightness, low cost and high safety factor. Complex and aging problems are prominent, resulting in defects such as deformation, cracks, and corrosion of pipelines, which can easily lead to oil and gas leakage, explosions, and other accidents, often causing disas...
