Ultrasonic phased array testing calibration device for tky pipe joint welds

Abstract

This utility model relates to the technical field of ultrasonic phased array testing devices, and proposes an ultrasonic phased array testing and calibration device for TKY pipe joint welds. The device includes: a fixed base plate and a frame, fixedly installed on the top of the fixed base plate. A groove is formed in the inner top wall of the frame, and a slider is slidably connected inside the groove. A motor is fixedly installed on one side of the frame, and the output end of the motor extends into the groove and is fixedly connected to a lead screw. By placing the pipe to be tested on the top of the fixed base plate, and then activating the electric telescopic rod, the probe is moved downwards to facilitate pipe testing. Simultaneously, activating the motor drives the lead screw to rotate inside the groove, which in turn causes the slider to slide inside the groove, moving the probe above the pipe for testing. This achieves automatic pipe scanning and testing, eliminating the need for manual probe handling and significantly improving work efficiency.

Description

Technical Field

[0001] This utility model relates to the technical field of ultrasonic phased array testing devices, specifically to an ultrasonic phased array testing and calibration device for TKY pipe joint welds. Background Technology

[0002] An ultrasonic phased array detector is a special testing instrument used in the field of safety science and technology. It is mainly used for ultrasonic testing of welds (including lap welds, corner welds, and butt welds) and corrosion.

[0003] A known Chinese patent (application number: CN202223191479.0) discloses a steel structure ultrasonic phased array testing instrument, including a phased array testing instrument body. The phased array testing instrument body is equipped with a fixed lifting strap. Arc-shaped grooves are formed around the perimeter of the phased array testing instrument body, and a buffer airbag is installed within each arc-shaped groove. The buffer airbag has a cylindrical structure. Auxiliary components that cooperate with the buffer airbags are provided on both sides of the phased array testing instrument body. By setting up buffer airbags, the elasticity of the buffer airbags facilitates initial protection of the four corners of the phased array testing instrument body. Simultaneously, the design of the auxiliary components allows the buffer airbags to deform when impacted by external force. The gas inside the buffer airbags impacts the piston, forcing the piston to compress the first spring. The elastic rebound of the first spring creates a certain rebound resistance, forcing the gas back into the buffer airbag, thus providing secondary buffering of the impact force and effectively protecting the phased array testing instrument body.

[0004] However, in implementing the relevant technology, the above-mentioned ultrasonic phased array testing instrument for steel structures has the following problems: In the process of use, the existing technology usually involves manually picking up the probe for scanning and testing, but it is difficult to perform automatic scanning and testing. As a result, long-term operation can easily lead to fatigue and affect accuracy. Therefore, the ultrasonic phased array testing and calibration device for TKY pipe joint welds was proposed.

Subsequently, by releasing the two clamping plates 12, the tension spring 13 drives the two clamping plates 12 to return to their original position, thus clamping and fixing the probe 8. At the same time, the anti-slip pads 14 on the clamping plates 12 are used to increase the friction between the clamping plates 12 and the probe 8 to prevent slippage.
