Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0045] A pipeline flaw detection device includes a flaw detection support platform 10, which includes: a platform seat 11; an adjustment motor 12, which is installed on one side of the platform seat 11; a bidirectional lead screw 13, which is rotatably connected to the inside of the platform seat 11 and one end of which is fixedly connected to the output shaft of the adjustment motor 12; a lead screw slider 14, which is symmetrically arranged on the outer side wall of the bidirectional lead screw 13 and is threadedly connected to the bidirectional lead screw 13;

[0046] When adjusting the bearing point, the adjusting motor 12 is started to drive the bidirectional lead screw 13 to rotate, so that the bidirectional lead screw 13 drives the two lead screw sliders 14 to move inward or outward synchronously, and the lead screw sliders 14 then drive the two upper flip assemblies 20 to move inward or outward synchronously, thereby achieving the purpose of adjusting the pipe bearing point;

[0047] The top of the platform seat 11 is slidably connected to two symmetrically distributed flipping assemblies 20, and the two flipping assemblies 20 are respectively connected to the two lead screw sliders 14. The flipping assembly 20 includes: a flipping seat 21, which is slidably connected to the top of the platform seat 11; a wheel seat 22, which is fixedly connected to the top of the flipping seat 21; a flipping motor 23, which is installed on the outer wall of the wheel seat 22; a flipping wheel 24, which is rotatably connected to the inner wall of the wheel seat 22, and the axis is fixedly connected to the output shaft of the flipping motor 23. The flipping wheel 24 includes: a wheel body 241; a wheel axle 242, which is arranged at the axis of the wheel body 241; an anti-skid sleeve 243, which is sleeved on the outer wall of the wheel body 241, and the outer wall of the anti-skid sleeve 243 has anti-skid patterns;

[0048] When the pipeline needs to be turned over, the turning motor 23 is started, so that the turning motor 23 drives the turning wheel 24 to rotate, and the turning wheel 24 drives the pipeline to rotate, so that the weld of the pipeline can be fully inspected. By setting the anti-skid sleeve 243 and setting anti-skid patterns on the outside of the anti-skid sleeve 243, the friction with the pipeline can be increased to avoid idling.

[0049] The top of the platform seat 11 is slidably connected with a flaw detection assembly 30, which includes: a flaw detection seat 31, which is slidably connected to the top of the platform seat 11; a flaw detection frame 32, which is fixedly connected to the top of the flaw detection seat 31; a top plate 33, which is installed on the top of the flaw detection frame 32; a liquid pump 34, which is fixedly connected to the top of the top plate 33; a liquid inlet pipe 35, which is arranged at the liquid inlet end of the liquid pump 34, and the liquid inlet pipe 35 is connected to the external developer; a nozzle 36, which is installed at the bottom of the top plate 33 and connected to the liquid outlet end of the liquid pump 34;

[0050] When performing flaw detection, first connect the liquid inlet pipe 35 on the liquid pump 34 to the developer tank, then start the liquid pump 34, so that the liquid pump 34 pumps the developer to the nozzle 36, and use the nozzle 36 to evenly spray the developer to the weld for flaw detection.

[0051] See also Figure 1-5 When inspecting the pipeline weld for acceptance, first adjust the position of the pipeline bearing point according to the length of the pipeline. When adjusting the bearing point, start the adjusting motor 12 to drive the bidirectional lead screw 13 to rotate, so that the bidirectional lead screw 13 drives the two lead screw sliders 14 to move inward or outward synchronously, and the lead screw slider 14 drives the two upper flip assemblies 20 to move inward or outward synchronously, so as to achieve the purpose of adjusting the pipeline bearing point. After the adjustment is completed, the pipeline weld is inspected.

When the pipeline needs to be flipped, start the flip motor 23 to make the flip motor 23 drive the flip wheel 24 to rotate, so that the flip wheel 24 drives the pipeline to rotate, so that the pipeline weld can be fully inspected.
