Automatic scanning frame based on ultrasonic detection and travel path method of automatic scanning frame in pipeline

Abstract

The invention discloses an automatic scanning frame based on ultrasonic detection and a travel path method of the automatic scanning frame in a pipeline. The automatic scanning frame comprises a fixing frame and a driving device for driving the automatic scanning frame to move, wherein a central control system is arranged in the fixing frame, first magnetic blocks are slidably installed at the front end and the rear end of the fixing frame, second magnetic blocks are arranged at turning positions of the outer wall of the complex aluminum pipeline, and the opposite surfaces of the first magnetic blocks and the second magnetic blocks are homopolar; and the first magnetic blocks are arranged at the front end and the rear end of the fixing frame respectively, when the scanning frame enters oneturning position of the pipeline, an angle of the turning position of the complex pipeline is determined according to a sliding change difference value of the front and rear first magnetic blocks andthe length of the scanning frame, and therefore the scanning frame can easily pass through the turning position of the complex pipeline. The automatic scanning frame solves the technical problem thatthe detection effect of a camera device can be affected by a media and light in the pipeline when the media in the pipeline cannot be completely emptied during detection.

Description

technical field [0001] The invention relates to the technical field of defect detection, in particular to an automatic scanning frame based on ultrasonic detection and its movement method in a pipeline. Background technique [0002] Ultrasonic testing has been widely used in the technical field of weld defect detection. The usual detection objects involve storage tanks and various pipelines. The prior art involves a feedback-type automatic scanning device that does not require manual hand-held Mobile detection, and it is not easy to deviate during the scanning process. It can automatically scan multiple welds, which improves the scanning efficiency of the scanning device and reduces the labor intensity of labor. [0003] A feedback-type automatic scanning device in the above-mentioned prior art judges the steering position through the camera device, so that the automatic scanning device can automatically complete the steering, but because the light in the pipeline is relativ...

Problems solved by technology

[0003] A feedback-type automatic scanning device in the above-mentioned prior art judges the steering position through the camera device, so that the automatic scanning device can automatically complete the steering, but because the light in the pipeline is dark, and the medium in the pipeline cannot After emptying, the medium and light in the pipeline will affect the detection effect of the camera device, so the device is not suitable for detection in complex pipelines
