Abstract
Description
Technical Field
[0001] This utility model relates to the field of non-destructive testing, specifically to a non-destructive testing device for detecting flaws in high-temperature pipelines. Background Technology
[0002] Non-destructive testing utilizes the acoustic, optical, magnetic, and electrical properties of materials to detect defects or inhomogeneities in the tested object without damaging or affecting its performance. It provides information such as the size, location, nature, and quantity of defects. High-temperature pipelines generally refer to metal thermal engineering pipelines that transport high-temperature and high-pressure materials. Non-destructive testing equipment is required for flaw detection in high-temperature pipelines.
[0003] A search revealed a non-destructive testing device for high-temperature pipeline flaw detection, with publication number CN217954423U. The device includes a belt with rotating wheels fitted at both the upper and lower parts. A driver is fixedly connected to the middle of the left end of the upper rotating wheel, and a pad is fixedly connected to the lower end of the driver. A screw is fixedly inserted into the middle of the right end of the lower rotating wheel, and a detection mechanism is threaded through the outer surface of the right side of the screw. Fixing devices are movably inserted into the left and right ends of the screw, and two stabilizing rods are fixedly connected between the two fixing devices. The pad is fixedly connected to the left fixing device, and a controller is fixedly connected to the middle of the front end of the right fixing device. This non-destructive testing device for high-temperature pipeline flaw detection, through its fixing devices, allows for stable installation on high-temperature pipelines, facilitating flaw detection by the testing mechanism.
[0004] The aforementioned patent, when performing flaw detection on pipelines, only inspects one side of the pipeline, resulting in low detection accuracy. Furthermore, if multiple sides need to be inspected, the equipment must be disassembled and reassembled, complicating the process and reducing detection efficiency.
[0005] Therefore, it is necessary to invent a non-destructive testing device for high-temperature pipeline flaw detection to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a non-destructive testing device for high-temperature pipeline flaw detection. It achieves all-round detection through axial movement and circumferential adjustment, thereby solving the problems of existing technologies that only inspect one side of the pipeline during flaw detection, resulting in low detection accuracy. Furthermore, if multiple sides need to be inspected, the equipment needs to be disassembled and reassembled, which complicates the process and reduces detection efficiency.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a non-destructive testing device for high-temperature pipeline flaw detection, comprising two fixing components, each fixing component comprising two semicircular rings joined together to form a circular ring, an arc-shaped frame slidably mounted on one of the semicircular rings, a connecting rod fixedly connected to the top of the arc-shaped frame, a mounting block fixedly connected to one end of the connecting rod, an electric slide rail fixedly mounted between opposite sides of the two mounting blocks, a moving block fixedly connected to the electric slide rail, a non-destructive testing instrument fixedly connected to the back of the moving block, and a clamping mechanism fixedly connected to one side of the mounting block.
[0008] The clamping mechanism includes a fixing block, a clamping rod penetrating the surface of the fixing block, one end of the clamping rod penetrating the semicircular ring and extending into the inner cavity of the semicircular ring, and the other end of the clamping rod being fixedly connected to a pull handle.
[0009] A limiting plate is fixedly connected to the surface of the clamping rod, and a spring is fixedly connected between the limiting plate and the side opposite to the fixing block and on the surface of the clamping rod.
[0010] The semicircular ring has an annular groove that works in conjunction with the arc-shaped frame. One end of the arc-shaped frame is located inside the annular groove, and the other end of the arc-shaped frame is located outside the semicircular ring.
[0011] Both the upper and lower ends of the arc-shaped frame are rotatably connected to rollers.
[0012] Connecting blocks are fixedly connected to the front and rear ends of one side of the two semicircular rings, and fastening bolts are provided between two adjacent connecting blocks, with fastening nuts provided on the surface of the fastening bolts.
[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0014] 1. The moving block is driven by the electric slide rail, which in turn moves the non-destructive testing instrument. The non-destructive testing instrument is used to perform non-destructive testing on the pipeline. After the test, the clamp rod can be pulled by the pull handle to move the clamp rod away from the clamp groove, thereby moving the arc frame and adjusting the position of the arc frame. This allows for adjustment of the position of the non-destructive testing instrument for retesting. The combination of axial movement and circumferential adjustment ensures that the non-destructive testing instrument can cover all areas of the pipeline, improving the accuracy and integrity of the test.
[0015] 2. Rollers are rotatably connected to both the upper and lower ends of the arc-shaped frame. The rollers contact the inner wall of the annular groove, converting sliding friction into rolling friction when the arc-shaped frame moves, effectively reducing movement resistance and providing stable support for the arc-shaped frame, ensuring a smooth and stable adjustment process.

Detailed Implementation
[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0025] This utility model provides, for example Figure 1-5 The non-destructive testing device for high-temperature pipeline flaw detection shown includes two fixing components 1. The fixing components 1 include two semi-circular rings 101, which are spliced together to form a circular ring. An arc-shaped frame 2 is slidably arranged on one of the semi-circular rings 101. A connecting rod 3 is fixedly connected to the top of the arc-shaped frame 2. A mounting block 4 is fixedly connected to one end of the connecting rod 3. An electric slide rail 5 is fixedly installed between the opposite sides of the two mounting blocks 4. A moving block 6 is fixedly connected to the electric slide rail 5. A non-destructive testing instrument 7 is fixedly connected to the back of the moving block 6. A clamping mechanism 8 is fixedly connected to one side of the mounting block 4.
[0026] The electric slide rail 5 adopts existing technology and is electrically connected to an external power source. When the electric slide rail 5 is working, it drives the moving block 6 to move horizontally along the length of the slide rail, thereby driving the non-destructive testing instrument 7 to move axially.
[0027] The non-destructive testing instrument 7 uses existing technology to perform flaw detection on the pipeline.
[0028] The clamping mechanism 8 includes a fixing block 81, a clamping rod 82 penetrating through the surface of the fixing block 81, one end of the clamping rod 82 penetrating through the semi-circular ring 101 and extending into the inner cavity of the semi-circular ring 101, and the other end of the clamping rod 82 is fixedly connected to a pull handle 83.
[0029] The semicircular ring 101 has four slots that cooperate with the locking rod 82, and the slots are evenly spaced.
[0030] A limiting plate 84 is fixedly connected to the surface of the locking rod 82, and a spring 85 is fixedly connected between the limiting plate 84 and the side opposite to the fixing block 81 and located on the surface of the locking rod 82.
[0031] In use, the spring 85 presses against the limiting plate 84, and the limiting plate 84 limits the locking rod 82, thereby ensuring the stability of the locking rod 82 during use.
[0032] The semicircular ring 101 is provided with an annular groove 9 for use with the arc frame 2. One end of the arc frame 2 is located inside the annular groove 9, and the other end of the arc frame 2 is located outside the semicircular ring 101. The arc frame 2 can rotate axially along the annular groove 9, thereby driving the non-destructive testing instrument 7 to rotate, adjusting the position of the non-destructive testing instrument 7, and performing all-round testing on the pipeline to improve the accuracy of the testing.
[0033] Rollers 10 are rotatably connected to both the upper and lower ends of the arc-shaped frame 2;
[0034] The roller 10 contacts the inner wall of the annular groove 9, converting sliding friction into rolling friction when the arc frame 2 moves, effectively reducing movement resistance, and providing stable support for the arc frame 2, ensuring a smooth and stable adjustment process;
[0035] Connecting blocks 11 are fixedly connected to the front and rear ends of one side of the two semi-circular rings 101. Fastening bolts 12 are provided between two adjacent connecting blocks 11, and fastening nuts are provided on the surface of the fastening bolts 12.
[0036] The splicing of the two semicircular rings 101 is achieved through the cooperation between the connecting block 11, the fastening bolt 12 and the fastening nut, which is simple to operate.
[0037] The working principle of this practical application is as follows:
[0038] Four semicircular rings 101 are spliced together in pairs and installed on the pipe to be inspected. The connection between two semicircular rings 101 is achieved by rotating the fastening bolts 12 and the fastening nuts. The electric slide rail 5 drives the moving block 6 to move, and the moving block 6 drives the non-destructive testing instrument 7 to move. The non-destructive testing instrument 7 performs non-destructive testing on the pipe. After the test, the lever 83 can be used to pull the clamp 82 to move the clamp 82 away from the clamping groove, thereby moving the arc frame 2 and adjusting the position of the arc frame 2, thereby adjusting the position of the non-destructive testing instrument 7. The pipe can be inspected from all angles. The operation is simple and practical.
[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
