Ultrasonic flaw detection tool for steel plate

Abstract

The invention provides an ultrasonic flaw detection tool for a steel plate. The ultrasonic flaw detection tool comprises a flaw detection head and further comprises a connecting pipeline, a fluid universal joint and a water spraying device which are sequentially connected together. The flaw detection head is arranged below the water spraying device, the connecting pipeline and the fluid universal joint are detachably connected, the fluid universal joint and the water spraying device are detachably connected, and the water spraying device and the flaw detection head are detachably connected. The flaw detection head is arranged at the lower end of the water spraying device, it can be guaranteed that the flaw detection head is located within an umbrella-shaped area formed by sprayed water flow, when a steel pipe is held by hand to enable the flaw detection head to move on the surface of the steel plate, a water film is generated between the flaw detection head and the steel plate, the water film serves as a coupling agent for ultrasonic flaw detection, and then flaw detection work is completed. The ultrasonic flaw detection tool can achieve the fast and water-saving flaw detection work, is simple in structure, low in manufacturing cost and wide in application range, overcomes the defects that a traditional steel plate ultrasonic flaw detection mode is low in efficiency, large in water resource consumption and the like and is worthy of popularization.

Description

technical field [0001] The invention relates to the field of ultrasonic flaw detection, in particular to a steel plate ultrasonic flaw detection tool. Background technique [0002] At present, water is needed as a coupling agent when ultrasonic testing is used on steel plates. The traditional ultrasonic testing method for steel plates is to sprinkle water on a large area of ​​the steel plate surface, and then use a hand-held flaw detection head to detect flaws on the steel plate surface. This method is inefficient and consumes a lot of water. , especially when the ambient temperature or the temperature of the steel plate is high, multiple sprinkling of water is required, resulting in a serious waste of water resources. Therefore, it is an urgent problem to be solved in the present invention to design a fast and water-saving steel plate ultrasonic flaw detection tool. Contents of the invention [0003] The object of the present invention is to design a steel plate ultrason...
