Embodiment

[0037] Such as Figure 2-8 Shown, based on the flaw detection method of the bulb flat steel ultrasonic automatic flaw detection device. Double-head flat steel 37 and sphere 35 detection adopts 6-channel symmetrical ball head two-way simultaneous scanning, and web 36 detection adopts 8-channel overlapping and covering scanning, which specifically includes the following steps:

[0038] 1) Arrange an 8-channel combined ultrasonic probe on the web 36 of the double-headed spherical flat steel 37, where the probe 53 at the 1st position of the web, the probe 54 at the 2nd position of the web, the probe 55 at the 3rd position of the web, and the 4th position of the web The number probe 56 is a 4P 30×5FG8Z double-precision straight probe arranged longitudinally; the web number 5 probe 57, the web number 6 probe 58, the web number 7 probe 59, and the web number 8 probe 60 are horizontal 4P 30×5FG8Z double-precision straight probes are arranged, the hard alloy wear-resistant block 47 of...

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 ...
