Description

Technical Field

[0001] This utility model relates to the technical field of pipe detection equipment, specifically an ultrasonic pipe detection triaxial scanning device. Background Technology

[0002] Pipe inspection is a crucial part of industrial non-destructive testing (NDT), primarily used to detect internal defects, wall thickness variations, corrosion, and blockages in metallic or non-metallic pipes. Common pipe inspection methods include ultrasonic testing (UT), eddy current testing (ECT), radiographic testing (RT), magnetic particle testing (MT), and endoscopy. Ultrasonic testing analyzes the internal structure of the pipe wall through high-frequency sound wave reflection, suitable for thickness measurement and crack detection; eddy current testing utilizes the principle of electromagnetic induction to quickly identify surface and near-surface defects; radiographic testing uses X-ray or gamma-ray imaging to clearly display the internal structure of the pipe, but requires high radiation protection; magnetic particle testing is suitable for detecting surface cracks in ferromagnetic materials; and endoscopy directly observes the internal condition of the pipe through optical or photographic methods. Pipe inspection is widely used in petroleum, chemical, power, and aerospace industries to ensure the safety and reliability of pipelines. With the development of intelligent technologies, automated inspection equipment (such as robotic endoscopic inspection systems) is becoming increasingly widespread, improving inspection efficiency and accuracy.

[0003] Pipe inspection often requires manual rotation of the pipe to facilitate the inspection process. In practice, this step presents significant inconveniences: firstly, manual rotation requires continuous force and a constant speed, which can easily lead to operator fatigue and disrupt the inspection rhythm over extended periods; secondly, the pipe's own weight or surface condition (such as adhering impurities or unevenness) may increase rotational resistance, resulting in unstable rotation speed and consequently affecting the continuity and accuracy of the inspection data; furthermore, in confined working spaces or batch inspection scenarios, manual rotation is inefficient and cannot meet the demands of high-efficiency inspection. Utility Model Content

[0004] The purpose of this invention is to provide a triaxial scanning device for ultrasonic pipe detection, which solves the problem that the pipe needs to be manually rotated during detection, which is very inconvenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a triaxial scanning device for ultrasonic pipe detection, comprising a base and a mounting frame. A movable seat is provided at the upper end of the mounting frame, a lifting frame is provided on the movable seat, an ultrasonic detector is provided on the lifting frame, and an auxiliary wheel is provided at the lower end of the ultrasonic detector.

A roller is provided inside the bracket, and a motor is provided on one of the brackets. A pipe is in contact with the roller, and the pipe is in contact with the auxiliary wheel. A threaded rod is rotatably connected inside the mounting frame, and a knob is fixedly connected to the end of the threaded rod away from the mounting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model separates the ultrasonic detection device from the pipe driving unit, adapting to flexible manufacturing and various pipe materials and installations. It is equipped with a movable base to drive the ultrasonic detector to move, and a motor and roller drive the pipe to rotate, so that the ultrasonic detector forms a spiral scanning trajectory on the pipe surface to cover the entire surface. The front end of the ultrasonic detector is designed with an auxiliary wheel, which adapts to the roundness of the pipe by gravity. After adjusting the height, it can maintain a fixed distance from the pipe surface, and the detection data is not affected by changes in roundness, deformation and distance.

[0013] 2. This utility model, by setting up components such as threaded rods and brackets, can adjust the spacing between rollers, so that the rollers can be used for pipes of different specifications. Furthermore, by setting up components such as limit frames, limit blocks, and springs, the spring force can drive the limit block on the limit frame to slide into the knob, thus keeping the rollers stable after adjustment.

A roller 31 is provided inside the bracket 3, and a motor 32 is provided on one of the brackets 3. A pipe 33 is in contact with the roller 31, and the pipe 33 is in contact with the auxiliary wheel 15.

[0018] Please see Figure 2-4 The mounting base 2 has a threaded rod 4 rotatably connected inside. The outer side of the threaded rod 4 is provided with positive and negative threads. The threaded rod 4 is threadedly connected to the bracket 3. The design of the threaded rod 4 allows for adjustment of the spacing between the rollers 31. A retaining ring 41 is fixedly connected to the outer side of the threaded rod 4. The retaining ring 41 contacts the mounting base 2. The design of the retaining ring 41 allows for limiting the position of the threaded rod 4. A knob 42 is fixedly connected to the end of the threaded rod 4 away from the mounting base 2. The knob 42 contacts the mounting base 2. A guide rod 43 is fixedly connected inside the mounting base 2. The guide rod 43 is slidably connected to the bracket 3. The design of the guide rod 43 allows for guiding the bracket 3. A limit mechanism 5 is provided on the mounting base 2.

[0019] Please see Figure 2-4 The limiting mechanism 5 includes a limiting frame 51, which is slidably connected to the outer side of the mounting base 2. A limiting block 52 is fixedly connected to the side of the limiting frame 51 near the knob 42. The limiting frame 51 contacts the knob 42, and the limiting block 52 is slidably connected to the knob 42. Through the design of the limiting block 52, the knob 42 can be limited. A slider 53 is fixedly connected to the side of the limiting frame 51 near the mounting base 2, and a sliding rod 54 is fixedly connected to the outer side of the slider 53. The slider 53 is slidably connected to the mounting base 2. The slide rod 54 is slidably connected to the mounting base 2. The mounting base 2 is internally fixedly connected to a limit ring 55.

[0020] The specific implementation process of this utility model is as follows: In use, by moving the limiting frame 51 away from the knob 42, the limiting frame 51 drives the slider 53 to move, the slider 53 drives the slide rod 54 to move within the limiting ring 55, the slide rod 54 squeezes the spring 56, and the limiting frame 51 drives the limiting block 52 to slide out of the knob 42, thus releasing the limitation on the knob 42; By rotating the knob 42, the knob 42 drives the threaded rod 4 to rotate, causing the threaded rod 4 to move in a threaded motion with the bracket 3, thereby causing the bracket 3 to move on the threaded rod 4, which in turn causes the bracket 3 to move the roller 31, thus allowing the distance between the two rollers 31 to be adjusted. By placing the pipe 33 on two rollers 31 and then starting the lifting frame 13 to move the ultrasonic detector 14, which in turn moves the auxiliary wheel 15 to contact the pipe 33, the pipe 33 can be kept stable during detection. Then, the motor 32 is started to rotate the rollers 31, which in turn rotate the pipe 33. This allows the ultrasonic detector 14 to form a spiral scanning trajectory on the surface of the pipe 33 to cover the entire surface.
