Embodiment Construction

[0027] The technical solutions of the various embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments described in the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative work are within the protection scope of the present invention.

[0028] Embodiments of the present invention, such as Figure 1 to Figure 3 As shown, an automatic scanning frame 21 based on ultrasonic detection is provided, including a fixed frame 1 and a driving device for driving the automatic scanning frame 21 to move. The fixed frame 1 is provided with a central control system, and the bottom of the fixed frame 1 There are four fixed blocks 2 at the end, and the fixed block 2 is rotatably connected with two sets of direction wheels. The firs...

Abstract

The invention discloses an automatic scanning frame based on ultrasonic detection and its movement method in a pipeline, including a fixed frame and a driving device for driving the automatic scanning frame to move. The first magnetic block is slidably installed, and the second magnetic block is provided at the turning of the outer wall of the complex aluminum pipe. When the scanning frame enters the turning of the pipeline, the difference between the sliding changes of the front and rear two first magnetic blocks and the length of the scanning frame itself determine the angle at the turning point of the complex pipeline, so that the scanning frame can pass through the complex pipeline relatively easily of the corner. It solves the technical problem that the medium and light in the pipeline will affect the detection effect of the camera device when the medium 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...
