Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of welding quality inspection, and more specifically, to a welding quality inspection device for a pipe welding machine. Background Technology

[0002] Currently, there are many shortcomings in the methods for inspecting the quality of welded pipes. Since the weld joint of a pipe is circumferential, ideally, the inspection should comprehensively cover every part of the weld joint. However, in practice, many manufacturers still use manual inspection. During manual inspection, inspectors rely on handheld inspection tools to move along the pipe surface. But this method is greatly affected by human factors. On the one hand, it is difficult for inspectors to ensure that each movement accurately covers the entire weld joint, easily leading to omissions and some areas going undetected. On the other hand, prolonged manual inspection can easily cause operator fatigue, further reducing the accuracy and comprehensiveness of the inspection.

[0003] Undetected welding defects, such as porosity, cracks, and incomplete penetration, can cause serious problems after the pipeline is put into use. These defects weaken the pipeline's strength and may lead to leaks or ruptures when subjected to pressure or corrosion. This can not only affect normal production but also cause safety accidents, resulting in economic losses and personal injury.

[0004] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a welding quality inspection device for a welded pipe machine, which solves the technical problem in the prior art that it is difficult for inspectors to ensure that the path of each movement can accurately cover the entire weld joint, which easily leads to omissions and causes some positions to be undetectable.

[0033] like Figures 1-4 As shown, it illustrates a welding quality inspection device for a welded pipe machine according to an embodiment of the present disclosure, comprising:

[0034] The base frame 1 and the platform 2 are fixed on the base frame 1;

[0035] The detection display device 3, the detection head 4, and the rolling detection component 5 are installed on the platform 2. The detection display device 3 is installed at the bottom and outside of the platform 2, the detection head 4 is installed on the platform 2, and the rolling detection component 5 is installed on the platform 2.

[0036] Support for mobile component 6 is provided on platform 2.

[0037] The rolling detection assembly 5 includes a bracket 5-1, which is fixed to the surface of the platform 2. A first cylinder 5-2 is installed at the bottom of the platform 2. The output end of the first cylinder 5-2 is connected to a side frame 5-3. A groove 5-4 is opened at the top of the bracket 5-1, and the detection head 4 is installed in the groove 5-4. A drive wheel 5-5 is rotatably connected to the side end face of the side frame 5-3. A drive motor 5-6 is installed at the bottom of the side frame 5-3. A transmission wheel 5-7 is provided at the output end of the drive motor 5-6 and at one end of the drive wheel 5-5. The transmission wheels 5-7 are connected by a toothed belt. A pair of support wheels 5-8 are rotatably connected to the side end face of the side frame 5-3. A column 5-9 is installed on the surface of the platform 2. A second cylinder 5-10 is installed in the column 5-9. A top frame 5-11 is provided at the output end of the second cylinder 5-10. A pair of pressure rollers 5-12 are rotatably connected to both ends of the bottom of the top frame 5-11.

[0038] In some examples, to achieve the effect of inspecting pipe welds by rolling, a rolling inspection component 5 is designed. This component includes a bracket 5-1 fixed to the surface of a platform to support the pipe. A first cylinder 5-2 is installed at the bottom of the platform 2, and a side frame 5-3 is provided at the output end of the first cylinder 5-2. The side frame 5-3 can be raised and lowered by the first cylinder 5-2. A groove 5-4 is opened at the top of the bracket 5-1 for installing an inspection head 4. The inspection head 4 can be used with the inspection and display device 3 to inspect the pipe welds and check for problems. A drive wheel 5-5 is rotatably connected to the side end face of the side frame 5-3, and a drive motor 5-6 is installed at the bottom of the side frame 5-3. The drive motor 5-6 provides the power to control the rotation of the pipe. Both the output end of 5-6 and one end of the drive wheel 5-5 are equipped with transmission wheels 5-7. The transmission wheels 5-7 are connected by a toothed belt. This transmission method can ensure the stability of power transmission, so that the drive wheel 5-5 drives the pipe to roll, so that the inspection head 4 can perform a comprehensive inspection of the weld. The side end face of the side frame 5-3 is rotatably connected to a pair of support wheels 5-8, which can support the pipe and ensure the stability of the pipe during the rolling process. The surface of the platform 2 is equipped with a column 5-9 and a second cylinder 5-10 is installed inside. The output end of the second cylinder 5-10 is equipped with a top frame 5-11. Both ends of the bottom of the frame are rotatably connected to a pair of downward pressure wheels 5-12, which can press down under the drive of the second cylinder 5-10, so that the pipe can rotate more stably.

[0039] like Figures 1-4 As shown, this embodiment proposes a support moving component 6 including several pairs of support frames 6-1. The support frames 6-1 are fixed on the surface of the platform 2 and distributed on both sides of the bracket 5-1. Support rollers 6-2 are rotatably connected inside the support frames 6-1.

[0040] In some examples, a moving assembly is designed to enable the support pipe to be pushed to the inspection point. This assembly includes several pairs of support frames 6-1, all of which are fixed to the surface of the platform 2. Support rollers 6-2 are installed on the upper end of the support frames 6-1. The support rollers 6-2 can support the bottom of the pipe, allowing the pipe to be pushed arbitrarily and easily adjusted to the weld.

[0041] For example, such as Figure 1 As shown, the bracket 5-1 has a Y-shaped structure, and the top of the bracket 5-1 has a semi-circular transition.

[0042] In some examples, the Y-shaped structure allows the support 5-1 to hold the pipe inside, preventing it from rolling off to the sides during pushing.

[0043] For example, such as Figure 1 As shown, the surface of the support roller 6-2 has a concave structure.

[0044] In some examples, the concave structural surface allows the support roller 6-2 to fit more closely to the pipe surface, resulting in more stable movement.

[0045] For example, such as Figure 1 As shown, the support wheel 5-8 is located on both sides of the drive wheel 5-5, the support wheel 5-8 is higher than the drive wheel 5-5, and the surface of the drive wheel 5-5 is an anti-slip structure surface.

[0046] In some examples, the anti-slip structural surface enables the drive wheel 5-5 to drive the pipe to rotate stably, and the two support wheels 5-8 support both ends of the bottom of the pipe, increasing the number of support points.

[0047] For example, such as Figure 2 As shown, the vertical position of the pressure roller 5-12 corresponds to the position of the support roller 5-8.

[0048] In some examples, the corresponding positions enable rapid clamping of the pipe.

[0049] In actual use: Place the pipe to be inspected on the support roller 6-2 of the support moving assembly 6, push the welded pipe to the inspection position so that the welded pipe is above the bracket 5-1 of the rolling inspection assembly 5, start the first cylinder 5-2 to raise the side frame 5-3, and the drive wheel 5-5 contacts the welded pipe. At the same time, start the second cylinder 5-10 to lower the top frame 5-11 and press the welded pipe with the lower pressure wheel 5-12. Start the drive motor 5-6. The drive motor 5-6 drives the drive wheel 5-5 to rotate through the transmission wheel 5-7 and the toothed belt. The drive wheel 5-5 drives the welded pipe to roll. The inspection head 4 inspects the annular weld joint of the welded pipe. The inspection data is transmitted to the inspection display device 3 in real time. After the inspection is completed, turn off the drive motor 5-6, and retract the second cylinder 5-10 and the first cylinder 5-2 in sequence. The pipe can then be removed.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
