Flat-bulb steel ultrasonic automatic flaw detection device and flaw detection method

Abstract

The invention relates to a flat-bulb steel ultrasonic automatic flaw detection device and a flaw detection method. The flaw detection device comprises a rack, a bulb automatic tracking detection device, a web automatic tracking detection device, a flaw detection trolley, a track, a flaw detection trolley driving device and a baiting rack; the automatic detection tracking device is arranged on therack, the flat-bulb steel is arranged on the flaw detection trolley, the flaw detection trolley driving device drives the flaw detection trolley and the flat-bulb steel to make reciprocating translational motion along the flaw detection trolley translation track; the bulb probe level direction performs real-time follow-up on the flat-bulb steel bulb plane; the web probe vertical direction performsreal-time follow-up on the flat-bulb steel web plane; the bulb probe automatically and vertically moves to an upper end from a lower end of the bulb, a web probe automatically and horizontally movesto the bulb from an outer end of the web so as to accomplish the flat-bulb steel partition detection; the flat-bulb steel makes reciprocating translational movement along the track to realize the ultrasonic flaw detection full process. The automatic ultrasonic flaw detection of the flat-bulb steel is realized, and the flaw detection rate is high, and the working efficiency is high, and the progress demand for ship construction can be satisfied.

Description

technical field [0001] The invention relates to the technical field of non-destructive testing, in particular to an ultrasonic automatic flaw detection device and a flaw detection method for spherical flat steel. Background technique [0002] Flat bulbs are medium profiles mainly used in shipbuilding and bridge building. Among them, flat bulbs for ships are key medium profiles for shipbuilding. Flat bulbs are divided into single-headed bulbs and double-headed bulbs according to the number of heads. steel. In recent years, with the rapid development of the shipbuilding industry, the demand for marine flat bulbs is strong. Generally, the main hulls of larger ships and regular ships are mostly made of marine bulbous flat steels, and the same thickness and material as the connected plates are used. For bones (also known as tendons or keels). [0003] At present, there is no automatic flaw detection device for bulbous flat steel, and manual hand detection is generally used for ...

AI Technical Summary

Problems solved by technology

[0003] At present, there is no automatic flaw detection device for bulbous flat steel. Manual detection is generally used for bulbous flat steel. Unstable coupling can easily lead to large fluctuations in detection sensitivity, which can easily lead to missed inspections, thus affecting the safety of ships. In addition, the efficiency of manual flaw detection is low, which in turn affects The output of symmetrical bulb flats cannot meet the schedule requirements of shipbuilding
