[0002] Steel pipe weld detection devices mainly include ultrasonic flaw detectors and automatic ultrasonic flaw detection equipment. These devices detect weld defects through the propagation characteristics of ultrasonic waves in materials. An ultrasonic flaw detector emits ultrasonic pulses through a probe, receives the reflected signals, converts them into electrical signals, and determines the existence, position, size, and nature of internal defects through signal processing and analysis. Automatic ultrasonic flaw detection equipment achieves relative scanning movement between the workpiece and the probe via mechanical auxiliary equipment, utilizing multi-channel ultrasonic flaw detectors for high-speed detection.

Apparently, the described embodiments are merely some rather than all of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative labor shall fall within the protection scope of the present invention.
[0031] Embodiment 1: Referring to Fig. 1 to Fig. 9, the present invention provides a technical solution: a steel pipe weld detection device with an adjustment structure, comprising a storage seat 1, wherein a moving strap 11 and a guide rail strap 12 are installed on one side of the storage seat 1. The moving strap 11 and the guide rail strap 12 are connected within the storage seat 1 via a winding mechanism 5. A detection seat 2 is installed on one side of the moving strap 11 and the guide rail strap 12. Fixing plates 17 are installed at one end of both the moving strap 11 and the guide rail strap 12. A fixing hook 18 is provided on one side of each fixing plate 17, and the fixing hook 18 is connected to the storage seat 1 via a buffer seat 7. The detection seat 2 comprises a detection housing 21, an installation base 16 installed on the inner side of the detection housing 21, and a detection plate 14 installed on one side of the installation base 16; an ultrasonic detection probe 13 is provided on the inner side of one end of the detection plate 14.
[0032] A moving seat 23 is provided at one end of the detection housing 21, an installation electric rod 24 is fixedly installed on the inner side of the moving seat 23, and a moving frame 25 is slidably installed on one side of the moving seat 23. A moving wheel 27 is rotatably installed on the inner side of the moving frame 25. A moving motor 26 is provided at one end of the moving frame 25, and an output shaft of the moving motor 26 is fixedly connected to the moving wheel 27. The cross-sectional shapes of both the moving strap 11 and the guide rail strap 12 are configured as U-shaped, and the moving wheel 27 is located between the moving strap 11 and the guide rail strap 12. A reinforced steel cable belt 112 is provided on the inner side of both the moving strap 11 and the guide rail strap 12. Anti-skid teeth 111 are provided on one side of both the moving strap 11 and the moving wheel 27, and an anti-wear roller 121 is provided on the inner side of the guide rail strap 12. In use, this ensures that the moving wheel 27 moves more stably within the moving strap 11 and the guide rail strap 12. By driving the moving wheel 27 to rotate via the moving motor 26, and in cooperation with the engagement of the anti-skid teeth 111 and the rotation of the anti-wear roller 121, the moving wheel 27 rotates and moves between the moving strap 11 and the guide rail strap 12, thereby causing the detection housing 21 and the ultrasonic detection probe 13 to move along the guide rail strap 12. The cross-sectional shape of the moving frame 25 is configured as a double-layered dovetail shape, and a dovetail groove is formed on one side of the moving seat 23 at a position corresponding to the moving frame 25. The moving frame 25 slides within the dovetail groove, which ensures more stable movement of the moving frame 25 and the moving wheel 27 when pushed by the installation electric rod 24 during use.
[0033] The winding mechanism 5 comprises installation baffles 54 fixed within the storage seat 1 and a winding roller 56 rotatably installed within the storage seat 1. Winding spiral fins 55 are provided at both ends of the winding roller 56, and the spiral directions of the winding spiral fins 55 at the two ends are opposite. The middle portion of the winding roller 56 is located between the installation baffles 54, and a transmission worm gear 53 is installed at the middle portion of the winding roller 56. A transmission worm 52 is engaged on one side of the transmission worm gear 53. One end of the transmission worm 52 passes through the storage seat 1 and is fixedly equipped with a winding handwheel 51.
[0034] Two winding rollers 56 are installed on the inner side of the storage seat 1. The moving strap 11 and the guide rail strap 12 are respectively wound onto the two winding rollers 56. The transmission worm gears 53 and the transmission worms 52 at the middle portions of the two winding rollers 56 are installed in a staggered manner, which facilitates the synchronous winding of the moving strap 11 and the guide rail strap 12 at both ends by the winding rollers 56 during use.
[0035] As can be seen from the above description, the present invention has the following beneficial effects: in use, the device is quickly strapped onto a steel pipe via the moving strap 11 and the guide rail strap 12; the tightness of the moving strap 11 and the guide rail strap 12 is adjusted via the winding mechanism 5; the detection seat 2 travels on the storage seat 1 and the guide rail strap 12; and internal defects of the steel pipe are fully detected via the ultrasonic detection probe 13 within the detection seat 2. Compared with traditional handheld probe detection, the detection device of the present invention has more stable detection movement and significantly improved detection accuracy during use, and the collected data can more accurately reflect the weld quality.
[0036] Embodiment 2: Referring to Fig. 1 to Fig. 9, on the basis of Embodiment 1, the present invention provides a technical solution: the buffer seat 7 comprises a fixed base 71 fixed on the storage seat 1 and a sliding column 72 slidably installed within the fixed base 71. A buffer spring 73 is installed on the inner side of the fixed base 71, and one end of the sliding column 72 presses against the buffer spring 73. A hanging hole is provided at one end of the sliding column 72 and is used for connecting the fixing hook 18. Vibrations generated are buffered by the sliding column 72 pressing against the buffer spring 73. An installation clamping plate 74 is installed on the outer side of the buffer spring 73, and damping sliding seats 75 are fixedly installed at both ends of the installation clamping plate 74. The installation clamping plate 74 is clamped onto the buffer spring 73 and fixed via the damping sliding seats 75. The damping sliding seats 75 at both ends of the installation clamping plate 74 respectively abut and slide against the inner wall of the fixed base 71 and the surface of the sliding column 72. A damping sliding plate 76 is provided on the inner side of one end of the sliding column 72, and a damping sliding groove 77 is provided on the inner wall of the fixed base 71. The damping sliding plate 76 is slidably installed within the damping sliding groove 77. Friction generated by the damping sliding seats 75 sliding within the fixed base 71 and the damping sliding plate 76 sliding within the damping sliding groove 77 provides damping, thereby enhancing vibration reduction and ensuring more stable movement.
[0037] By adopting the technical solution of the buffer seat 7, the fixing plate 17 is connected to the storage seat 1 via the buffer seat 7, and vibrations generated by the movement of the detection seat 2 during use are buffered, thereby reducing the phenomenon of fatigue damage at the connection points due to vibration.
[0038] Working Principle and Operating Process: In use, the winding handwheel 51 is rotated to drive the transmission worm 52 to rotate. The transmission worm 52 drives the transmission worm gear 53 and the winding roller 56 to rotate, thereby releasing the moving strap 11 and the guide rail strap 12. First, the guide rail strap 12 is sleeved onto the steel pipe and hung on the sliding column 72 via the fixing plate 17 and the fixing hook 18. Then, the transmission worm 52 is rotated in the reverse direction to drive the winding roller 56 to wind and tighten the guide rail strap 12 onto the steel pipe for fixation; during tightening, the sliding column 72 slides and presses against the buffer spring 73. Next, the moving strap 11 is installed on the buffer seat 7 via the fixing plate 17 and the fixing hook 18, and the detection seat 2 is installed on the outer side of the moving strap 11. According to the positions of the moving strap 11 and the guide rail strap 12, the moving strap 11 is then installed within the moving seat 23. The moving frame 25 and the moving wheel 27 are pushed by the installation electric rod 24 to move, so that the moving strap 11 is limited within the moving seat 23. Then, the moving strap 11 is tightened via the winding mechanism 5 so that the moving strap 11 presses against the moving wheel 27, thereby positioning the moving wheel 27 between the moving strap 11 and the guide rail strap 12. The detection seat 2 is installed on the moving strap 11 and the guide rail strap 12. The moving wheel 27 is driven to rotate by the moving motor 26, and in cooperation with the engagement of the anti-skid teeth 111 and the rotation of the anti-wear roller 121, the moving wheel 27 rotates and moves between the moving strap 11 and the guide rail strap 12, thereby causing the detection housing 21 and the ultrasonic detection probe 13 to move along the guide rail strap 12, enabling the ultrasonic detection probe 13 to detect the steel pipe weld. During detection, the moving strap 11 and the guide rail strap 12 can be adjusted multiple times as needed, thereby allowing for a complete circular detection of the steel pipe weld, and multiple detections ensure the accuracy of the detection and better localization of weld defects. Vibrations generated during movement are buffered by the sliding column 72 pressing against the buffer spring 73. Meanwhile, friction generated by the damping sliding seats 75 sliding within the fixed base 71 and on the sliding column 72, and the damping sliding plate 76 sliding within the damping sliding groove 77, provides damping, which enhances vibration reduction and ensures more stable movement. After use, the detection seat 2 is removed, and the moving strap 11 and the guide rail strap 12 are wound into the storage seat 1, making it more convenient for storage and carrying.
