Walking mechanism of flaw detector for round pipeline

Abstract

The invention relates to the field of flaw detectors, in particular to a walking mechanism of a flaw detector for a round pipeline. The walking mechanism comprises a flaw detection mechanism, a limiting mechanism, a flange, a dust removal mechanism, a transmission mechanism and a cleaning mechanism. When the flaw detector walks, the dust removal mechanism is powered on to generate gas while rotating, and furthermore, as the dust removal mechanism generates wind energy in an annular array, the dust removal mechanism cleans dust on the inner wall of a pipeline needed to be detected in advance ina walking process of the whole mechanism, so that the flaw detection mechanism cleans dust of an undetected pipeline in advance favorably, and therefore, the condition that detection of the pipelineby the flaw detection mechanism is affected by dust is avoided. When the flaw detection mechanism walks, the dust removal mechanism cleans dust of the undetected pipeline in advance, the transmissionmechanism is driven while the dust removal mechanism rotates, and after the transmission mechanism rotates, the transmission mechanism located at the bottom of the flaw detection mechanism generates wind energy to blow dust cleaned by the dust removal mechanism to the direction of the undetected pipeline, so that dust is prevented from being accumulated in the pipeline.

Description

technical field [0001] The invention relates to the field of flaw detectors, in particular to a traveling mechanism of a flaw detector for circular pipelines. Background technique [0002] The flaw detector is generally non-destructive flaw detection. The flaw detector is specially used for shipbuilding, petroleum, chemical industry, machinery, aerospace, transportation and construction and other industrial sectors to check the welding quality of materials and parts such as hulls, pipelines, high-pressure vessels, boilers, aircraft, vehicles and bridges. , and the quality of various light metals, rubber, ceramics and other processed parts, showing the surface and internal defects of the parts processed and welded by the material, to evaluate the quality of the product. Shows the location, shape and size of the discontinuity. It can detect extremely fine cracks, hairlines, white spots, folds, inclusions and other defects on the surface of the material. It has high detection ...

AI Technical Summary

Problems solved by technology

[0003] However, the current pipeline flaw detector directly puts the flaw detector into the pipeline to be inspected when inspecting the inner wall of the pipeline, and the flaw detector starts to walk after entering the pipeline to be inspected. Walking in the uncleaned pipeline, it is difficult to accurately detect the damage of the inner wall of the pipeline, which affects the quality of the pipeline, and the current flaw detector only detects the pipeline when inspecting the pipeline, the dust and sundries at the bottom of the pipeline If it is not cleaned, it is easy to cause the blockage of the pipeline when using the pipeline, which will affect the normal use of the pipeline
