Description

Technical Field

[0001] The utility model relates to the technical field of steel structure weld detection, in particular to a nondestructive flaw detection device for steel structure welds. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings and other fields. The quality of the welds inside the steel structure is the basis for ensuring the overall quality of the steel structure. The quality inspection of the welds of steel structure components is particularly important. Ultrasonic flaw detection can be used to implement the weld inspection of steel structures. Ultrasonic flaw detection mainly uses ultrasonic waves to penetrate deep into the steel structure, and judges and inspects the defect position inside the steel structure through the waveform display of the reflected wave. It has the characteristics of not damaging the structure and high detection speed.

The utility model can clamp and fix the tubular steel by the upper clamping plate cooperating with the lower clamping plate through the setting of the positioning mechanism, and drive the ultrasonic probe to rotate around the weld of the tubular steel by rotating the ferrule, thereby detecting the weld of the tubular steel, without manually lifting the tubular steel for detection, thereby avoiding affecting the progress and accuracy of the flaw detection, and through the setting of the adjusting mechanism, can drive the moving block to move on the screw rod by rotating the screw rod, thereby driving the steel structure clamping cylinder to move, thereby sending the clamped tubular steel into the interior of the flaw detection cylinder for detection, thereby facilitating the detection of the tubular steel weld.
