Orbital Automatic Phased Array Ultrasonic Scanner

Abstract

The invention discloses a track-type automatic phased array ultrasonic scanner, which comprises a main frame, a control box and a probe frame. The four sides of the main frame are sequentially provided with a first idler assembly, a driving assembly, and a second idler assembly. The wheel assembly and the connecting plate, the first idler assembly and the second idler assembly are adjustable and connected with respect to the main frame and are clamped on the same side of the track in front and rear for use together, and the driving assembly passes through the lock provided on the main frame. The tightening assembly contacts or separates from the other side of the track, and the first idler assembly is provided with an encoder; the control box is set on the top surface of the main frame and is electrically connected with the driving assembly to control the movement direction and speed of the main frame; The probe holder is connected with the connection board. The ultrasonic scanner device of the invention has good running stability, accurate detection data, strong applicability and versatility, and improves the detection efficiency of the device.

Description

technical field [0001] The invention relates to the technical field of ultrasonic equipment, in particular, to an orbital automatic phased array ultrasonic scanner. Background technique [0002] The phased array inspection technology based on sector scanning and linear scanning is mainly used for butt rings of land or submarine long-distance pipelines, offshore platform process pipelines and other steel structure process pipelines including carbon steel and 316 stainless steel and other special materials. Non-destructive testing of welds. Generally speaking, the above-mentioned testing device includes a data processing unit and a data acquisition unit. At present, the data acquisition mode of the data acquisition unit mainly uses a manual chain device to support phased array probes and other probes, and uses an encoder. Record the walking distance, and manually control the walking speed and direction. Such a data collection method is slow, has a great influence of human fac...

AI Technical Summary

Problems solved by technology

This kind of data collection method is slow, the influence of human factors is relatively large, and the quality of data collection is difficult to guarantee.

With the wide application of automatic welding technology, the laying efficiency of long-distance pipelines on land and on the seabed has been continuously improved. The trackless manual scanning device represented by the chain scanner has been difficult to meet the production needs. Problems leading to re-scans, the cost impact of which can be significant for expensive pipeline laying, especially subsea pipelines
