Workpiece surface ultrasonic phased array automatic detection device

Abstract

The invention discloses an automatic detection device for a workpiece surface ultrasonic phased array. The automatic detection device comprises a crawler, a scanning guide rail, an ultrasonic phased array instrument and a motion controller, wherein the crawler is arranged on a to-be-detected workpiece and can move on the to-be-detected workpiece, one end of the crawler is arranged on the scanningguide rail, an ultrasonic phased array instrument is arranged on the scanning guide rail, and the scanning guide rail is arranged on the surface of the to-be-detected workpiece and collects ultrasonicdetection data of the surface of the to-be-detected workpiece. According to the detection device provided by the invention, the pipeline crawl device drives the ultrasonic phased array probe to automatically detect, so that the safety condition of the pipeline can be better judged, and safety quality production can be better controlled; the liquid supply module and the liquid suction module workin cooperation to provide ultrasonic detection coupling water supply, meanwhile, overflowing coupling water is sucked away and filtered into the water supply water tank, and therefore cyclic utilization of the ultrasonic detection coupling water is achieved; consumption of ultrasonic detection coupling water is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of ultrasonic detection, in particular to an automatic ultrasonic phased array detection device for the surface of a workpiece. Background technique [0002] The plastic-lined pipe is made of ordinary carbon steel pipe as the matrix, and is lined with thermoplastic engineering plastics with excellent chemical stability. After cold-drawing composite or rotational molding, it has both the mechanical properties of steel pipes and the corrosion resistance and slow-bonding of engineering plastics. It is not easy to grow microorganisms, and it is an ideal pipeline for transporting media such as acids, alkalis, salts, and corrosive gases. [0003] The advantages of plastic-lined pipes make them widely used in industrial production. [0004] 1. Chemical industry: process pipes and discharge pipes for transporting corrosive gases, liquids, and solid powders in the manufacturing of acids, alkalis, and salts, fertiliz...

AI Technical Summary

Problems solved by technology

[0010] After long-term use of plastic-lined pipes, the inner lining and the carbon steel pipe will be debonded, which will cause the inner lining layer to be easily damaged after losing the support and protection of the steel pipe, which will cause corrosive gas, liquid, and solid powder to enter the steel pipe, causing the steel pipe to be corroded and harmful to the environment. Pollution and potential safety hazards to production safety

[0011] In view of the problem of debonding of plastic-lined pipelines, it is necessary to study a debonding detection device for plastic-lined pipelines, which can detect the debonding of pipelines in service
