Abstract

The invention provides a mechanical system of a high-definition pipeline magnetic flux leakage detector for the on-line detection of the metal loss degree of a pipeline, which relates to the technology fields of the measurement of magnetic variables and the size of linear thickness, and the pipeline system. A carrier of the mechanical system is divided into two sections; the two sections are connected through a universal joint (12); the shell body of a first section is a circular pipe-shaped magnet (5), wherein an anti-collision head (1) is arranged at the front end of the circular pipe-shaped magnet, and the universal joint (12) is arranged at the tail part thereof; a front supporting mechanism (2), a front driving leather cup (3), a front steel brush (4), a main probe system (7), a rear steel brush (9), a rear driving leather cup (10), a rear steel brush (9) and a rear supporting mechanism (11) are arranged at the periphery of the shell body in sequence from front to back; the shell body of a second section, in which an electronic storehouse (14) is arranged, is a circular pipe-shaped storehouse, wherein the universal joint (12) arranged at the front end of the circular pipe-shaped storehouse, and the tail part thereof is sealed; a probe system (13) with an inner diameter and an outer diameter, a tail supporting mechanism (15) and an odometer wheel system (16) are arranged at the periphery of the shell body in sequence from front to back. The mechanical system has the advantage that the dynamic performance and the precision of the detector are improved.

Description

technical field [0001] The invention is a mechanical system of a high-definition pipeline magnetic flux leakage detector for online detection of the metal loss degree of pipelines, and relates to the technical fields of measuring magnetic variables, measuring linear dimensions of thickness and pipeline systems. Background technique [0002] The buried steel pipelines in operation, especially the steel pipelines that have been in operation for a long time, will have a certain degree of corrosion. In order to ensure the safe operation of buried pipelines, online corrosion detection of pipelines is usually carried out regularly. At present, the internal detection method is used for pipeline corrosion detection, mainly the magnetic flux leakage detection method. Although the current magnetic flux leakage detectors for buried pipelines have been used for many years, they have certain accuracy and information processing capabilities, and can basically meet the needs of pipeline co...
