Description

Technical Field

[0001] This utility model relates to the field of welded pipe flaw detection technology, and in particular to a welded pipe spot probe flaw detection device. Background Technology

[0002] Welded steel pipes, also known as welded pipes, are steel pipes made by rolling and welding steel plates or strips. They are typically available in 6-meter lengths. The production process for welded steel pipes is simple, efficient, and offers a wide variety of specifications with low equipment investment, but their strength is generally lower than that of seamless steel pipes.

[0003] Since welded pipes are made by welding, their internal defects need to be inspected after processing. Currently, the most common inspection methods are manual handheld ultrasonic flaw detectors. The whole process is time-consuming, labor-intensive, and inefficient. In addition, manual inspection is prone to omissions, which affects the accuracy of the inspection results. Utility Model Content

[0033] Please see Figure 1-4 This utility model provides a welded pipe spot detection device, comprising:

[0034] A welded pipe placement rack 1, wherein a placement groove 2 is provided on the welded pipe placement rack 1;

[0035] The driving component includes a first mounting frame 3 disposed at one end of the welded pipe placement rack 1, a first motor 4 disposed on the first mounting frame 3, a drive wheel 5 disposed on the first motor 4, the drive wheel 5 being connected to a first rotating shaft 7 via a belt 6, a first turntable 8 disposed on the first rotating shaft 7, the first turntable 8 being rotatably connected to the first mounting frame 3 via the first rotating shaft 7, and a first mounting groove 9 disposed on the first turntable 8;

[0036] A clamping component is provided at the other end of the welded pipe placement rack 1. A second turntable 10 is provided on the clamping component, and a second mounting groove 11 is provided on the second turntable 10.

[0037] The flaw detection component includes a movable unit 12 disposed on the side of the welded pipe placement rack 1, a slide 13 disposed on the movable unit 12, and a flaw detection head 14 disposed on the slide 13.

[0038] The clamping component includes a second mounting bracket 17 disposed at the end of the welded pipe placement rack 1. A cylinder 18 is mounted on the second mounting bracket 17, and a mounting plate 19 is mounted on the piston rod of the cylinder 18. A second rotating shaft 20 is mounted on the mounting plate 19, and the second turntable 10 is rotatably connected to the mounting plate 19 via the second rotating shaft 20. During flaw detection, the second turntable abuts against the end of the welded pipe to prevent movement during the process, thus improving the flaw detection quality. After flaw detection is completed, the cylinder drives the second turntable away from the welded pipe placement rack, causing the second turntable to detach from the welded pipe, facilitating the removal of the welded pipe.

[0039] The mounting plate 19 has a slider 15 at its bottom, which is slidably connected to a slide rail 16, which is mounted on the second mounting bracket 17. This allows the mounting plate to move more stably.

[0040] The moving unit 12 includes a control box 121 mounted on the welded pipe placement rack 1. A second motor 122 is mounted on the control box 121. The output end of the second motor 122 is connected to a threaded rod 123, which is rotatably connected to the inner wall of the control box 121. A threaded sleeve 124 is threadedly connected to the surface of the threaded rod 123, and the top of the threaded sleeve 124 is fixedly connected to the bottom surface of the slide 13. The second motor drives the threaded rod to rotate, thereby moving the threaded sleeve and the slide in the back-and-forth direction, facilitating the movement of the flaw detector head.

[0041] The top surface of the control box 121 is provided with a through-groove, and the inner wall of the groove is slidably connected to the surface of the carriage. The groove provides space for the carriage to move and is arranged along the length of the control box.

[0042] The placement groove 2, the first mounting groove 9, and the second mounting groove 11 are located on the same straight line, which facilitates the fixing of the welded pipe.

[0043] Working principle: By placing the welded pipe in the placement slot on the welded pipe placement rack, with one end of the pipe inserted into the first mounting slot, a cylinder drives the mounting plate to move towards the welded pipe placement rack, allowing the other end of the pipe to be inserted into the second mounting slot, thus fixing the welded pipe in place. A flaw detector head then inspects the surface of the welded pipe. A first motor drives a drive wheel to rotate, which in turn drives a first turntable via a belt, causing the welded pipe to rotate and thus performing flaw detection around its circumference. A moving unit then moves the slide to perform a full-scale flaw detection, achieving rapid and comprehensive inspection of the welded pipe. Compared to manual inspection, this method saves time and labor, effectively improving the efficiency of welded pipe flaw detection. It has a high degree of automation, is less prone to omissions, ensures the accuracy of the flaw detection results, and has good practicality.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
