Automatic scanning device based on ray detection and moving method of automatic scanning device in pipeline

Abstract

The invention discloses an automatic scanning device based on ray recognition and a moving method of the automatic scanning device in a pipeline. The automatic scanning device comprises a fixing frameand a driving device for driving the automatic scanning device to move. Transmitting devices are installed at the front end and the rear end of the fixing frame respectively, and a receiving device is arranged at the turning position of the outer wall of a complex pipeline. A central control system is electrically connected with the receiving device, a first motor and the driving device. The transmitting devices and the receiving device are arranged, X-rays have high penetrating power, and the X-ray receiver is installed on the outer wall of the turning position of the complex pipeline. Whenthe X-ray receiver receives corresponding signals, the signals can be fed back to the automatic scanning device, and the automatic scanning device adjusts steering according to an angle alpha measuredin advance. Secondly, X-rays can also be used for carrying out defect detection on the turning position of the pipe wall, and the detected result can also be fed back to the central control system. The technical problem that when media in a pipeline cannot be completely emptied during detection, the detection effect of a camera device can be affected by the media and light in the pipeline is solved.

Description

technical field [0001] The invention relates to the technical field of defect detection, in particular to an automatic scanning device based on ray detection and its operation 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 relatively d...

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 Completely empty, the medium and light problems in the pipeline will affect the detection effect of the camera device, so this device is not suitable for detection in complex pipelines
