[0002] Pipe bolts are critical fasteners in piping systems, and their installation position and tightening condition directly affect the safety and stability of the entire system. Accurate bolt positioning and inspection are essential during pipeline installation, maintenance, and repair. Deviations in bolt position or inadequate tightening can lead to leaks, loosening, or even breakage at pipe connections, causing serious safety accidents. Therefore, quickly and accurately locating bolts and promptly inspecting their tightening condition and internal defects are crucial for ensuring the safe operation of piping systems.

[0003] However, current methods for bolt positioning and inspection mainly rely on manual visual inspection or simple mechanical measuring tools. These methods are not only inefficient but also susceptible to human factors, resulting in poor positioning accuracy, limited detection range, and difficulty in detecting hidden defects such as internal cracks and corrosion in bolts. Therefore, there is an urgent need for a bolt inspection device that is simple in structure, easy to operate, fast in detection, and accurate in positioning to improve pipeline maintenance efficiency and safety.

[0022] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0023] Please see Figure 1-5 The pipe bolt rapid positioning ultrasonic testing device includes four sliding rods 1. The surfaces of the multiple sliding rods 1 are slidably connected to the testing mechanism 2. Clamping mechanisms 3 are provided on both the left and right sides of the sliding rods 1.

[0024] The testing mechanism 2 includes a square profile plate 201, on the surface of which a groove is provided. A sliding rod 1 is slidably connected to the surface of the groove. A lead screw 202 is threaded through the top of the square profile plate 201. A movable plate 203 is rotatably connected to the bottom of the lead screw 202. An ultrasonic testing probe 204 is fixed on the surface of the movable plate 203. A controller 205 and a display screen 206 are fixed on the top of the square profile plate 201.

[0025] Through the above technical solution, the sliding rod 1 serves as the support track for the entire detection mechanism 2, allowing the square profile plate 201 to slide on its surface, thereby achieving rapid positioning of the pipe bolt. The square profile plate 201 cooperates with the sliding rod 1 through a groove to ensure smooth sliding and accurate positioning. The lead screw 202 is threadedly connected to the top of the square profile plate 201. Rotating the lead screw 202 can drive the movable plate 203 to move up and down, thereby adjusting the distance between the ultrasonic detection probe 204 and the bolt being tested, ensuring good contact between the probe and the bolt surface. The controller 205 is used to control the working status of the probe, and the display screen 206 displays the detection waveform and results in real time, making it easy for operators to judge whether there are defects inside the bolt. This mechanism is compact in design, easy to operate, and can achieve precise adjustment and rapid positioning of the probe position, improving detection efficiency and accuracy.

[0026] The clamping mechanism 3 includes an upper arc-shaped clamping plate 301, a lower arc-shaped clamping plate 302 hinged to the bottom of the upper arc-shaped clamping plate 301, and two extension plates 303 fixed to the top of the upper arc-shaped clamping plate 301. The extension plates 303 are fixedly connected to one end of the sliding rod 1.

[0027] Through the above technical solution, the clamping mechanism 3 is composed of an upper arc-shaped clamping plate 301 and a lower arc-shaped clamping plate 302, which are connected by a hinge, allowing for flexible opening and closing, and facilitating quick clamping onto the outer wall of the pipe. The extension plate 303 fixed at the top of the upper arc-shaped clamping plate 301 is connected to the sliding rod 1 to form a stable support structure, keeping the sliding rod 1 in a horizontal state and ensuring smooth sliding of the detection mechanism 2. This structural design allows the device to be quickly installed on the pipe, and the installation is convenient, improving the stability and reliability of the detection. It is suitable for rapid on-site deployment and high-frequency detection operations.

[0028] A screw 304 is rotatably connected to the surface of the lower arc-shaped clamping plate 302, and a fastening cap 305 is threaded onto the surface of the screw 304.

[0029] Through the above technical solution, the screw 304 and the fastening cap 305 are used together. By rotating the fastening cap 305, it can be moved along the axial direction of the screw 304, thereby adjusting the clamping force between the upper arc-shaped clamping plate 301 and the lower arc-shaped clamping plate 302, and enhancing the stability and reliability of clamping.

[0030] Both the upper arc-shaped clamping plate 301 and the lower arc-shaped clamping plate 302 have threaded bolts 306 through them, and a clamping block 307 is fixedly connected to one end of the bolts 306.

[0031] The above technical solution allows for adjustment of the contact pressure between the clamping block 307 and the pipe surface by rotating the shank bolt 306, thereby improving the adaptability and stability of the clamping, ensuring that the device position remains unchanged during the testing process, improving testing accuracy and repeatability, and making it suitable for bolt testing tasks under various complex working conditions.

[0032] A pin 209 is provided on one side of the square profile plate 201, and a plurality of pin holes 4 are provided on the surface of the sliding rod 1 on one side to accommodate the pin 209. A locking hole 208 is provided on the surface of the square profile plate 201 to accommodate the pin 209.

[0033] Through the above technical solution, the pin 209 is used in conjunction with the pin hole 4 and the locking hole 208 to fix the detection mechanism 2 after it slides to the designated position. After the pin 209 is inserted into the pin hole 4 and the locking hole 208, it restricts the sliding of the square profile plate 201 and prevents it from being displaced during the detection process.

[0034] A guide rod 207 slides through the surface of the square-shaped plate 201, and the bottom of the guide rod 207 is fixedly connected to the top of the movable plate 203.

[0035] Through the above technical solution, when the lead screw 202 drives the movable plate 203 to move up and down, the guide rod 207 plays a guiding and limiting role, preventing the movable plate 203 from rotating or deviating.

[0036] The square-shaped plate 201 has mounting grooves on both the front and rear sides, and a transparent observation window 210 is fixed to the inner wall of the mounting groove.

[0037] With the above technical solution, the transparent observation window 210 is installed in the mounting grooves on the front and rear sides of the square profile plate 201. The operator can observe the contact between the ultrasonic testing probe 204 and the bolt surface in real time through the observation window, which is convenient for timely adjustment of the probe position or coupling status. This structure improves the visibility of the device operation, makes it easier for on-site personnel to judge the testing status, and avoids testing failure due to poor coupling or position deviation.

[0038] The ultrasonic testing probe 204 is a single-crystal longitudinal wave straight probe.

[0039] Through the above technical solution, the single-crystal longitudinal wave straight probe generates a high-frequency longitudinal wave through a piezoelectric crystal, which is perpendicularly incident into the bolt. When it encounters a defect or interface, it generates a reflected echo, which is received by the same probe and converted into an electrical signal. This type of probe has a simple structure and high sensitivity, and is suitable for detecting internal defects in metal bolts. Through the longitudinal wave propagation method, it can effectively identify internal defects such as cracks, pores, and corrosion in bolts, thereby improving the accuracy and reliability of the detection.

[0040] Working Principle: In use, the sliding rod 1 is first fixed to the outer wall of the pipe via the clamping mechanism 3. The upper arc-shaped clamping plate 301 and the lower arc-shaped clamping plate 302 are clamped to both sides of the pipe via a hinged structure. The clamping force is adjusted by the screw 304 and the fastening cap 305 to ensure stable installation. Subsequently, the operator adjusts the shank bolt 306 to make the clamping block 307 fit tightly against the pipe surface, further enhancing clamping stability. After installation, the operator slides the square profile plate 201 on the sliding rod 1 to align it with the bolt to be tested, and fixes the position by inserting the pin 209 into the pin hole 4 and locking hole 208. Next, ultrasonic coupling agent is used to fill the tiny gap between the ultrasonic testing probe 204 and the bolt surface, ensuring that ultrasonic waves can smoothly penetrate into the bolt. Then, the screw 202 is rotated to move the movable plate 203 downwards, bringing the ultrasonic testing probe 204 into contact with the bolt surface. The guide rod 207 acts as a guide during this process, preventing probe deviation. Because the probe uses a single-crystal longitudinal wave straight probe, it emits ultrasonic waves through the piezoelectric effect to enter the bolt's interior. Upon encountering defects or reflecting echoes from the bottom surface, the probe receives and transmits these echoes to the controller 205, ultimately displaying the waveform on the display screen 206. During this process, the operator can observe the contact between the probe and the bolt through the transparent observation window 210 to ensure good coupling. The entire inspection process can achieve multi-point coverage by sliding the probe, ensuring comprehensive inspection. This device has a compact structure, is easy to operate, and can achieve rapid bolt positioning and efficient inspection, making it suitable for daily maintenance and troubleshooting of industrial pipelines.
