Detailed Implementation

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] Please see Figures 1 to 3This utility model provides a technical solution: a probe holder device for ultrasonic eddy current testing of seamless steel pipes, including a support base plate 1. A positioning mechanism 2 is provided on the top of the support base plate 1. The positioning mechanism 2 includes two L-shaped support columns 21. The L-shaped support columns 21 provide a stable installation foundation and guiding reference for the entire positioning system. The bottoms of the two L-shaped support columns 21 are fixedly connected to the top of the support base plate 1. Two support plates 22 are fixedly connected to the top of the support base plate 1. The support plates 22 and the L-shaped support columns 21 work together to support the seamless steel pipe a5. Before and during the fixing of the seamless steel pipe a5 by the positioning plate 27, the support plates 22 lift the seamless steel pipe a5 to prevent it from falling due to its own weight. A sliding block 23 is slidably connected to the outside of the L-shaped support column 21. The sliding block 23 acts as a motion transmission component in the positioning mechanism 2, connecting the L-shaped support column 21 and the connecting column 25, and converting the power transmitted by the power component 28 into its own power. The sliding movement along the L-shaped support column 21 drives the connecting column 25 and the positioning plate 27 to achieve the positioning and release action of the seamless steel pipe a5. The top of the sliding block 23 is fixedly connected to the connecting column 25. The two connecting columns 25 will move simultaneously towards the middle and both sides along the trajectory of the slide groove 24, thereby driving the positioning plate 27 fixedly connected to the connecting column 25 to achieve the centering and separation action to adapt to seamless steel pipes a5 of different diameters. The positioning plate 27 is fixedly connected to the adjacent side of the connecting column 25. The connecting column 25 is the key connecting component for the positioning plate 27 to achieve movement. The connecting column 25 plays the role of a bridge for force and motion transmission. The top of the two sliding blocks 23 is slidably connected to the sliding limit plate 26. The sliding limit plate 26 is the direct receiving component for the power transmission of the power component 28, and at the same time provides motion guidance and limit for the connecting column 25. It directly contacts the seamless steel pipe a5. Through the connection with the connecting column 25, the seamless steel pipe a5 is clamped, fixed and released under the action of power.

[0025] The sliding limit plate 26 has two sliding grooves 24 inside. A power assembly 28 is fixedly connected to the bottom of the support base plate 1. The power assembly 28 includes an electric telescopic rod 281, which is the power source for the positioning mechanism 2 and provides power for the movement of the sliding limit plate 26. The bottom of the electric telescopic rod 281 is fixedly connected to the inside of the top side of the support base plate 1. A connecting cylinder 282 is fixedly connected to the driving end of the electric telescopic rod 281. The connecting cylinder 282 connects the electric telescopic rod 281 and the sliding limit plate 26, converting the telescopic movement of the electric telescopic rod 281 into the linear sliding movement of the sliding limit plate 26. The top of the seamless steel pipe a5 is fixedly connected to the bottom of the sliding limit plate 26, the bottom of the seamless steel pipe a5 is slidably connected to the top of the sliding limit plate 26, the middle of the seamless steel pipe a5 is slidably connected to the adjacent side of the two positioning plates 27, the outside of the two connecting columns 25 is fixedly connected to the inside of the slide groove 24, the top of the support base plate 1 is provided with an adjustment mechanism 3, the bottom of the support base plate 1 is fixedly connected with an anti-slip pad 6, the top right side of the L-shaped support frame 4 is fixedly connected with a control panel 7, the right side of the transmission line 341 is fixedly connected to the inside of the control panel 7, the top of the positioning mechanism 2 is slidably connected with the seamless steel pipe a5, and the seamless steel pipe a5 is the detection object of this device.

[0026] like Figure 4 and Figure 5As shown, the adjustment mechanism 3 includes a drive slide rail 32, which provides horizontal movement guidance and support for the adjustment mechanism 3. The bottom of the drive slide rail 32 is fixedly connected to the inside of the top side of the support base plate 1, and the top of the drive slide rail 32 is fixedly connected to a support base plate 31. The support base plate 31 also provides a stable mounting foundation for the upper components, ensuring the structural stability of each component during operation. The top of the support base plate 31 is fixedly connected to an L-shaped support frame 4, which integrates the probe assembly 33, cleaning assembly 35, etc., into a unified working unit. The probe assembly 33 is fixedly connected to the bottom left side of the L-shaped support frame 4. The probe assembly 33 includes a probe protective shell 331, which prevents damage from external dust, impurities, collisions, etc., ensuring the normal operation and use of the probe assembly 33. For extended lifespan, the top of the probe protective housing 331 is detachably connected to the top left side of the L-shaped support frame 4. The probe protective housing 331 is quickly installed and removed from the L-shaped support frame 4 using bolts. An arc-shaped electromagnetic ultrasonic coil 333 is fixedly connected inside the probe protective housing 331. The arc-shaped electromagnetic ultrasonic coil 333 uses the principle of electromagnetic induction to excite ultrasonic waves and receive the reflected ultrasonic signals, converting the ultrasonic signals into electrical signals, thereby realizing the detection of seamless steel pipe a5. A permanent magnet 332 is fixedly connected to the bottom of the arc-shaped electromagnetic ultrasonic coil 333. The permanent magnet 332 ensures the efficiency and stability of electromagnetic ultrasonic conversion, thereby ensuring the accuracy and reliability of the detection signal. The permanent magnet 332 is fixedly connected to the bottom side of the probe protective housing 331. A cleaning component 35 is fixedly connected to the bottom left side of the L-shaped support frame 4.

[0027] The cleaning component 35 includes a follower column 351, which facilitates the adjustment of the height of the arc-shaped cleaning plate 352 to accommodate seamless steel pipes a5 of different diameters, ensuring effective cleaning. The top of the follower column 351 is detachably connected to the top and bottom of the L-shaped support frame 4. The follower column 351 and the L-shaped support frame 4 are quickly installed and disassembled using bolts. The bottom of the follower column 351 is fixedly connected to the arc-shaped cleaning plate 352. As the arc-shaped cleaning plate 352 moves with the L-shaped support frame 4, it can closely adhere to the surface of the seamless steel pipe a5 and slide, effectively removing surface impurities and providing clean surface conditions for subsequent testing. This prevents impurities from affecting the propagation of ultrasonic waves and the test results. The bottom of the arc-shaped cleaning plate 352 is slidably connected to the top of the seamless steel pipe a5. A cylinder 36 is fixedly connected to the top of the support base plate 31. The cylinder 36 provides driving force to the L-shaped support frame 4 through its telescopic movement, driving the L-shaped support frame 4 and the probe component 33 and cleaning component 35 above it. The cylinder 36 moves up and down, and its drive end is fixedly connected to the bottom right side of the L-shaped support frame 4. A connecting component 34 is fixedly connected inside the top side of the L-shaped support frame 4. The connecting component 34 includes a transmission line 341, which transmits the detection signal generated by the arc-shaped electromagnetic ultrasonic coil 333 to an external signal processing device, and at the same time transmits the control signal of the external device to the arc-shaped electromagnetic ultrasonic coil 333, ensuring stable signal transmission during the detection process. The transmission line 341 is fixedly connected to the inside of the top side of the L-shaped support frame 4. A threaded connector 342 is slidably connected to the outside of the transmission line 341. The threaded connector 342 ensures that the transmission line 341 will not be damaged due to position changes, ensuring the continuity of signal transmission. A threaded post 343 is fixedly connected to the top of the probe protective shell 331. The threaded post 343 realizes the mechanical and electrical connection between the probe assembly 33 and the L-shaped support frame 4. The external thread of the threaded post 343 is connected to the inside of the threaded connector 342.

[0028] Working principle: First, during use, the two L-shaped support columns 21 provide support, while the support plates 22 at both ends support the seamless steel pipe a5. At the same time, when the power component 28 pushes, it drives the sliding limit plate 26 to the right, causing the sliding block 23 to slide on the L-shaped support column 21, which in turn causes the connecting column 25 and the positioning plate 27 to move in the center. When the electric telescopic rod 281 retracts, it pulls the connecting column 282 to slide to the right, thereby releasing the positioning plate 27 to open the seamless steel pipe a5, thus achieving fixation according to different seamless steel pipes a5.

[0029] Secondly, during use, the L-shaped support frame 4 is adjusted left and right by sliding the drive slide rail 32, and the cylinder 36 adjusts the L-shaped support frame 4 up and down, thereby adjusting the probe protective shell 331 and the permanent magnet 332 up, down, left and right. At the same time, when the drive slide rail 32 is adjusted, the probe protective shell 331 and the permanent magnet 332 are detected. First, the dust and impurities on the seamless steel pipe a5 are cleaned by the follower column 351 and the arc-shaped cleaning plate 352. The use of the anti-slip pad 6 can reduce slipping. The permanent magnet 332 and the arc-shaped cleaning plate 352 are flexibly installed by bolts.

[0030] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
