Description

Technical Field

[0001] This utility model relates to the field of nondestructive testing technology, and in particular to a nondestructive testing device for penetrant testing. Background Technology

[0002] Building construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of buildings. Before and after welding, the metal support columns or metal pipes used in the construction process need to be inspected with non-destructive testing instruments to observe whether the welds between metal parts are qualified, to look for any hidden damage, and to determine whether the workpiece is qualified, as well as whether there are any internal defects in the metal parts such as cracks, sand holes, pores, white spots, inclusions, etc.

[0003] When applying for this utility model, the applicant, through a search, discovered a Chinese patent that discloses a "non-destructive testing penetration device," application number "202222005366.0." This patent mainly uses a wire that is confined by a partition, preventing it from being wrapped, resulting in a simple structure that saves time and effort and effectively avoids the probe being exposed to the outside, which inevitably leads to collisions with other external objects. However, protecting the probe is also of paramount importance. Therefore, in traditional methods, the probe is easily bumped during transport, affecting the detection. Thus, based on the applicant's invention, a non-destructive testing penetration detection device has been invented, solving the problem that the probe is easily bumped during transport in traditional methods, affecting the detection. Utility Model Content

[0004] The purpose of this invention is to provide a non-destructive testing device for penetrant detection, which solves the problem that the probe is easily bumped or knocked during transport, affecting the detection process, in traditional methods.

[0012] The above-mentioned solution has the following beneficial effects:

[0013] 1. This utility model comprises: a winding rod, a transmission line, a non-destructive testing probe, and a fastening screw. By rotating the winding rod, the transmission line can be rotated, achieving a winding operation. After winding, the length of the non-destructive testing probe can be easily controlled, preventing the transmission line from twisting or knotting.

Detailed Implementation

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-4This utility model discloses a non-destructive testing device for penetrant detection, comprising: a main body 1, a winding rod 4 rotatably connected to one side of the top of the main body 1, a door 6 hinged to one end of the front of the main body 1, and a non-destructive testing probe 9 disposed inside the door 6. The non-destructive testing probe 9 can perform non-destructive testing on pipelines. This technology utilizes existing technology, where clamping plates 8 are held on both sides of the non-destructive testing probe 9. When the non-destructive testing probe 9 needs to be stored, the clamping plates 8 expand outwards, while the rotating rod 14 provides rotatable support at both ends, enabling the sliding block 13 to expand against it. Rotating rods 14 are rotatably connected to both outer ends of the clamping plates 8, and a sliding block 13 is rotatably connected to the end of the rotating rod 14 away from the clamping plates 8. A sliding rod 11 is slidably fitted inside the sliding block 13. The clamping plates 8 and the inner wall of the main body 1... A damper 16 is fixedly connected between the clamping plate 8 and the rotating rod 14. When swaying occurs, the clamping plate 8 and the rotating rod 14 rotate to support each other, which can elastically compress the support spring 12 to achieve a buffering effect. At the same time, the damper 16 can dampen the vibration generated by the clamping plate 8, reduce the vibration frequency, and facilitate the reset function. A winding rod 4 is rotatably connected to the top end of the main body 1 of the detection device. By rotating the winding rod 4, the transmission line 5 can be rotated to realize the winding operation. After winding, it is easy to control the length of the non-destructive testing probe 9 and prevent the transmission line 5 from twisting and knotting. A support spring 12 is sleeved on one end of the slide rod 11. The support spring 12 is elastically compressed. After compression, it can fix the non-destructive testing probe 9 between the clamping plates 8. The support spring 12 and the slider 13 are fixedly connected. A concave plate 15 is sleeved on the top end of the non-destructive testing probe 9.

[0025] A transmission line 5 is wound around the outside of the winding rod 4. One end of the transmission line 5 is electrically connected to the main body 1 of the detection device, and the other end of the transmission line 5 is electrically connected to the non-destructive testing probe 9. A fastening screw 7 is threadedly connected to one side of the winding rod 4. By rotating the fastening screw 7, it engages with the winding rod 4. The bottom end of the fastening screw 7 abuts against the main body 1 of the detection device to achieve a limit and prevent the winding rod 4 from rotating on its own. The fastening screw 7 and the main body 1 of the detection device engage in abutment. Handles 3 are hinged to the middle of both ends of the main body 1 of the detection device. The bottom end of the non-destructive testing probe 9 is fitted with a rubber layer 10, and the rubber layer 10 is fixedly connected to the inner wall of the main body 1 of the detection device.

[0026] Working principle: In use, the take-up rod 4 is rotated, which in turn rotates the transmission line 5, achieving a take-up operation. After take-up, the length of the non-destructive testing probe 9 can be easily controlled, preventing twisting and knotting of the transmission line 5. Once the desired length is reached, the fastening screw 7 is rotated, engaging with the take-up rod 4. The bottom end of the fastening screw 7 abuts against the main body 1 of the testing device, achieving a limit stop and preventing the take-up rod 4 from rotating on its own. The non-destructive testing probe 9 can perform non-destructive testing on pipelines. This technology utilizes… In the existing technology, when the non-destructive testing probe 9 needs to be stored, the clamping plate 8 expands outward, while the rotating rod 14 rotates at both ends to support the slider 13, which expands against it. The support spring 12 is elastically compressed, and after compression, the non-destructive testing probe 9 can be fixed between the clamping plates 8. When shaking occurs during carrying, the clamping plate 8 and the rotating rod 14 rotate to support the support spring 12, which can elastically compress it to achieve a buffering effect. At the same time, the damper 16 can dampen the vibration generated by the clamping plate 8, reduce the vibration frequency, and facilitate the reset function.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
