Description

Technical Field

[0001] This utility model belongs to the technical field of pipeline inspection equipment, specifically referring to a device for detecting defects in pipeline circumferential welds. Background Technology

[0002] In pipeline engineering, the quality of circumferential welds directly affects the safety and reliability of the pipeline system. Therefore, defect detection of circumferential welds is a crucial step. However, existing methods for detecting defects in pipeline circumferential welds have the following problems:

[0003] 1. Traditional inspections often rely on manual handheld detectors to inspect the circumferential welds of pipelines. This is not only labor-intensive, but also the accuracy of the inspection is greatly affected by human operation, and it is easy to miss or misdetect.

[0004] 2. Some testing devices require external auxiliary tools for fixation. For pipelines with multiple circumferential welds, installation, adjustment and disassembly must be repeated for each test, which is cumbersome, inefficient and difficult to meet the needs of batch testing.

[0005] To address this issue, a device for detecting defects in pipe circumferential welds is proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is that the existing methods for detecting defects in pipeline circumferential welds are labor-intensive, have low detection efficiency, are cumbersome to operate, and are difficult to adapt to the detection of multiple circumferential welds.

[0007] To achieve the above functions, the technical solution adopted by this utility model is as follows: a device for detecting defects in pipe circumferential welds, including a pipe and a collar disposed on the pipe, a slider is slidably disposed on one side wall of the collar, and a weld detector is fixedly connected to the upper end of the slider, a convenient moving component is disposed on the inner side of the collar, and a buckle is fixedly disposed on the pipe.

[0008] Furthermore, the convenient moving component includes movable wheels disposed opposite to each other at the upper and lower ends of the inner side of the pipe.

[0009] Furthermore, the lower movable wheel is fixedly connected to the collar, and the upper movable wheel is slidably connected to the collar. A T-shaped screw is threadedly connected to the upper end of the collar, and the lower end of the T-shaped screw extends through into the collar and abuts against the upper movable wheel.

[0010] Furthermore, a limiting block is slidably provided on the inner side of the collar, and a T-shaped screw is rotatably connected to one side of the limiting block. One end of the T-shaped screw extends through the collar and outwards, and is threadedly connected to the collar.

[0011] Furthermore, the limiting block is made of rubber material.

[0012] Furthermore, a slide rail is fixedly provided on one side wall of the collar, and the slider slides within the slide rail for limitation.

[0013] The beneficial effects of this utility model by adopting the above structure are as follows:

[0014] 1. By fitting the collar onto the pipeline and using a convenient moving component, the collar can move axially along the pipeline. At the same time, the slider drives the weld detector to slide along the slide rail on the collar, enabling continuous detection of multiple circumferential welds on the pipeline. This replaces the manual handheld detector or the repetitive operation required by using external auxiliary tools, greatly improving detection efficiency and reducing labor intensity.

[0015] By rotating the T-screw, the upper moving wheel can be moved up and down, adjusting the distance between the upper and lower moving wheels to adapt to pipes of different diameters, thus enhancing the versatility and applicability of the device.

[0016] 2. By twisting the T-shaped screw, the limiting block can be moved towards the pipeline, so that the limiting block is in close contact with the outer wall of the pipeline, thereby temporarily fixing the collar and ensuring that the collar will not be displaced during the inspection process, thus guaranteeing the inspection accuracy of the weld detector.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] like Figure 1-4 As shown, in order to achieve the above functions, the technical solution adopted by this utility model is as follows: A device for detecting defects in pipe circumferential welds includes a pipe 1 and a collar 2 set on the pipe 1. A slide rail 10 is fixedly opened on one side wall of the collar 2. A slider 3 is slidably set inside the slide rail 10. A weld detector 9 is fixedly connected to the upper end of the slider 3. A convenient moving component is set inside the collar 2. A buckle 5 is fixedly set on the pipe 1.

[0026] like Figure 1-4 As shown, the convenient moving component includes moving wheels 4 disposed at the upper and lower ends of the inner side of the pipe 1. The lower moving wheel 4 is fixedly connected to the collar 2, and the upper moving wheel 4 is slidably connected to the collar 2. A T-shaped screw 6 is threadedly connected to the upper end of the collar 2, and the lower end of the T-shaped screw 6 extends through into the collar 2 and abuts against the upper moving wheel 4.

[0027] Based on the diameter of pipe 1, rotate the T-screw 6 to push the upper moving wheel 4 downward, ensuring that both the upper and lower moving wheels 4 are in close contact with the outer wall of pipe 1, thus installing the collar 2 onto pipe 1. Pushing the collar 2, under the action of the moving wheels 4, allows the collar 2 to move smoothly along the axial direction of pipe 1. When it moves to the vicinity of the circumferential weld, it is ready for inspection.

[0028] Example 2:

[0029] Based on Example 1, such as Figure 1-4 As shown, a limiting block 7 is slidably installed on the inner side of the collar 2. The limiting block 7 is made of rubber, and a T-shaped screw 8 is rotatably connected to one side of the limiting block 7. One end of the T-shaped screw 8 passes through the collar 2, extends outward, and is threadedly connected to the collar 2. When the collar 2 moves to the position of the circumferential weld to be inspected, the T-shaped screw 8 is twisted, causing the limiting block 7 to move towards the pipe 1 until the limiting block 7 is tightly fitted against the outer wall of the pipe 1, thus temporarily fixing the collar 2. Subsequently, the sliding slider 3 is slidable, causing the weld detector 9 to move along the slide rail 10 to perform a comprehensive inspection of the circumferential weld.

[0030] After inspecting one section of the circumferential weld, twist the T-bolt 8 in the reverse direction to separate the limiting block 7 from the pipe 1, releasing the fixation. Then, push the collar 2 to the next section of the circumferential weld. Repeat the above fixing and inspection steps. The clip 5 can be used to temporarily fix the collar 2 in a specific position on the pipe 1 when the device is not in use, preventing it from sliding freely.
