Description

Technical Field

[0001] The utility model relates to the technical field of magnetic particle flaw detectors, in particular to an adjustable magnetic particle flaw detector. Background Technique

[0002] After the pipeline welding work is completed, it is often necessary to use a magnetic particle flaw detector to detect the weld to ensure the welding quality of the pipeline. Magnetic particle flaw detection can detect defects such as cracks, hair cracks, white spots, folds, and inclusions in ferromagnetic materials. It has high detection sensitivity, can visually display the position, shape, size, and severity of the defects, and has good repeatability in checking defects. However, the currently used circular magnetic particle flaw detector is not convenient to adjust and use according to the diameter size of the workpiece during use, and can only be used for specific sizes, increasing the cost of workpiece production.

[0003] For example, the application number is 202121592648.4. The utility model discloses a high-efficiency adjustable magnetic particle flaw detector, which includes a magnetic particle flaw detector main body, a magnetic powder storage bottle, and an air pump for extracting magnetic powder. An electromagnetic coil is fixedly arranged on the inner side of the installation cavity, and a spraying pipe is arranged inside the installation cavity; the inner ring of the magnetic particle flaw detector main body is communicated with a telescopic powder spraying pipe through the spraying pipe, and a telescopic rod is fixedly installed between the inner rings of the magnetic particle flaw detector main body corresponding to the powder spraying pipes. The installation end of the magnetic powder storage bottle is screwed with the installation seat, and the input end of the spraying pipe is connected with the output end of the air pump through a connecting pipe. This high-efficiency adjustable magnetic particle flaw detector, through the setting of the telescopic powder spraying pipe and the telescopic rod, is not only convenient to adjust and use according to the diameter of the workpiece, but also has the function of recycling the excess magnetic powder ejected, reducing the production cost of the workpiece and improving the production efficiency of the workpiece. However, this magnetic particle flaw detector has no restrictions on iron powder, which is easy to cause more iron powder leakage, is not convenient to quickly fix the device on the pipeline, and is not convenient to prevent magnetic powder leakage when replacing magnetic powder.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and an adjustable magnetic particle flaw detector is proposed. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0024] Such as Figures 1 - 3As shown in the figure, an adjustable magnetic particle flaw detector includes a first mounting frame 1. The first mounting frame 1 is semicircular and consists of two parts. On one side of the first mounting frame 1, there is a handle 2 fixedly installed. The opposite sides of the handles 2 are slidably connected to each other. In the middle of the inside of the handle 2, there is a spring 3 fixedly installed, and a total of eight springs 3 are provided. At the opposite ends of the springs 3, there is a bolt 4 fixedly installed. During use, the first mounting frame 1 is buckled on the surface of the pipeline. After the handles 2 coincide, the limiting block 5 is rotated so that it is located between the handles 2, and in this way, the first mounting frame 1 can be fixed, thereby quickly installing the device on the surface of the pipeline and improving work efficiency.

[0025] Furthermore, the spring 3 can insert the bolt 4 into the slot 6 in the limiting block 5. And when the limiting block 5 rotates, after the bolt 4 retracts, under the action of the spring 3, it re-enters another slot 6 to re-fix the limiting block 5, which can improve the efficiency during locking.

[0026] As Figure 2 , Figures 4 - 5As shown in the figure, the bolt 4 is slidably connected to the handle 2 at the same time. A limiting block 5 is rotatably arranged in the middle of the handle 2, and there are also two limiting blocks 5. Slots 6 are opened at both the upper and lower ends of the limiting block 5. The number of slots 6 is the same as the number of bolts 4. The bolt 4 is slidably connected to the slot 6 at the same time. The lower end of the first mounting bracket 1 is fixedly provided with a mounting box 7, and a threaded rod 8 is fixedly arranged at the lower end inside the mounting box 7. A bottle 9 is arranged below the threaded rod 8, and the bottle 9 is slidably connected to the mounting box 7. A first bracket 10 is fixedly arranged in the middle of the bottle 9, and the first bracket 10 is cross-shaped. The first bracket 10 is engaged with the threaded rod 8, and a second bracket 11 is arranged below the first bracket 10. The second bracket 11 is also cross-shaped, and an elastic component 12 is fixedly arranged in the middle of the upper end of the second bracket 11. A sealing plate 13 is fixedly arranged at the upper end of the elastic component 12. The sealing plate 13 is slidably connected to the bottle 9 at the same time. A clamping groove 14 is fixedly arranged on one side of the first mounting bracket 1, and a second mounting bracket 15 is slidably arranged inside the clamping groove 14. The second mounting bracket 15 is also composed of two semi-circular rings, and a fastening bolt 16 is rotatably arranged at the intersection of the second mounting bracket 15. The other end of the fastening bolt 16 is engaged with the first mounting bracket 1. A dust-proof cloth 17 is fixedly arranged at the end of the second mounting bracket 15 away from the first mounting bracket 1, and the dust-proof cloth 17 is trumpet-shaped. An elastic band 18 is fixedly arranged at the end of the dust-proof cloth 17 away from the second mounting bracket 15, and a magnetic strip 19 is fixedly arranged on the side of the dust-proof cloth 17. When replacing the magnetic powder, the bottle 9 is unscrewed from the mounting box 7. As the bottle 9 is unscrewed, the threaded rod 8 moves away from the sealing plate 13, so that it resets under the action of the elastic component 12, sealing the bottle 9 to prevent the magnetic powder from leaking. In this way, more magnetic powder leakage can be avoided, thus ensuring the cleanliness of the working environment. After the device is installed on the pipeline, the second mounting bracket 15 is stuck in the clamping groove 14, and the fastening bolt 16 is aligned with the connection of the first mounting bracket 1 and tightened. After the dust-proof cloth 17 is sleeved on the outside of the pipeline, the magnetic strips 19 are attached together. In this way, the device can be assembled quickly and conveniently, and the sprayed magnetic powder is restricted within a certain range through the cooperation of the elastic band 18 and the dust-proof cloth 17, so as to facilitate its recycling.

[0027] Furthermore, the sealing plate 13 is arranged at the bottleneck of the bottle 9, which can not only facilitate the sealing of the bottle 9 by the sealing plate 13, but also increase the space and efficiency for the magnetic powder to pass through when the sealing plate 13 moves downward.

[0028] Working principle: When using this adjustable magnetic particle flaw detector, first, during use, buckle the first mounting frame 1 on the surface of the pipeline. After the handles 2 coincide, rotate the limit block 5 so that it is located between the handles 2, thus fixing the first mounting frame 1, and the device can be quickly installed on the surface of the pipeline, thereby improving work efficiency. Secondly, when replacing the magnetic powder, unscrew the bottle 9 from the mounting box 7. As the bottle 9 is unscrewed, the threaded rod 8 moves away from the sealing plate 13, and it resets under the action of the elastic component 12 to seal the bottle 9 and prevent magnetic powder leakage. This can avoid a large amount of magnetic powder leakage and ensure the cleanliness of the working environment. Finally, after the device is installed on the pipeline, snap the second mounting frame 15 into the card slot 14, align the fastening bolt 16 with the connection of the first mounting frame 1 and tighten it. After putting the dust-proof cloth 17 on the outside of the pipeline, stick the magnetic strips 19 together. In this way, the device can be assembled quickly and conveniently, and the ejected magnetic powder can be restricted within a certain range through the cooperation of the elastic band 18 and the dust-proof cloth 17 for easy recycling. This is the working principle of this adjustable magnetic particle flaw detector.
