Description

Technical Field

[0001] This utility model relates to the field of X-ray flaw detection technology, and in particular to an X-ray non-destructive testing device for industrial steel structures. Background Technology

[0002] X-ray nondestructive testing utilizes the difference in X-ray penetration and absorption to detect internal defects without damaging the object. It visually presents the morphology and location of defects through imaging and is applicable to both metallic and non-metallic materials. It is widely used in industrial manufacturing, aerospace, and petrochemical fields, but is limited by energy and involves radiation, requiring protective measures. Currently, it is developing towards digitalization and intelligentization.

[0003] Traditional X-ray source and detector positioning mechanisms have significant design limitations. The tracks are mostly fixed, rigid structures, allowing only linear movement in a single direction, and the angle adjustment range is also very limited. This makes it difficult to achieve comprehensive coverage when inspecting curved welds on large, irregularly shaped steel structures or complex internal cavities of small, precision components. Inspectors must repeatedly adjust the workpiece position manually or disassemble and reassemble the positioning components, a cumbersome and time-consuming process. Manual operation can also easily cause the X-ray source and detector central axis to deviate, resulting in blurred images or missed detections, severely impacting inspection efficiency and result reliability.

[0004] Based on this, an X-ray non-destructive testing device for industrial steel structures is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an X-ray non-destructive testing device for industrial steel structures in order to solve the above-mentioned problems.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An X-ray non-destructive testing device for industrial steel structures includes a base, a Y-axis connected to the upper end of the base, a vertical frame slidably connected to the Y-axis, an X-axis connected to the upper end of the vertical frame, a testing column connected to one side of the X-axis, an emitting end connected to one end of the testing column, and an adjustment mechanism for adjusting the X-ray testing angle of the emitting end connected to the X-axis.

[0008] Preferably, a rotating disk is rotatably connected to the upper end of the base.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. This application adopts a cylinder structure, which utilizes the extension and retraction of the cylinder in conjunction with its horizontal movement to enable the adjustment of the flaw detection column angle, thereby changing the X-ray flaw detection angle. After the cylinder extension and retraction adjustment is completed, the adjusted state can be maintained, which greatly improves the stability of the structure during flaw detection.

[0015] 2. This application adopts a rotating disk structure, which can drive the industrial steel structure on it to rotate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-Figure 3 This utility model provides a technical solution:

[0023] An X-ray non-destructive testing device for industrial steel structures includes a base 1, a Y-axis 3 connected to the upper end of the base 1, a vertical frame 4 slidably connected to the Y-axis 3, an X-axis 5 connected to the upper end of the vertical frame 4, a testing column 12 connected to one side of the X-axis 5, an emitting end 13 connected to one end of the testing column 12, and an adjustment mechanism for adjusting the X-ray testing angle of the emitting end 13 connected to the X-axis 5.

[0024] Specifically, such as Figure 1 and Figure 2 As shown, a rotating disk 2 is rotatably connected to the upper end of the base 1. The orientation of the steel structure placed on it can be changed by rotating disk 2, and the angle of the flaw detection column 12 can be adjusted to meet various flaw detection needs.

[0025] Specifically, such as Figure 1 and Figure 3 As shown, a rack 6 is connected to the upper end of the X-slide shaft 5, and an upper slider 7 is slidably connected to the upper end of the X-slide shaft 5. A motor 16 is connected to the upper slider 7, and a gear 17 is connected to the output end of the motor 16. The gear 17 and the rack 6 mesh with each other. The operation of the motor 16 can drive the gear 17 to rotate, thereby causing the upper slider 7 connected to the motor 16 to slide on the X-slide shaft 5.

[0026] Specifically, such as Figure 3 As shown, the adjustment mechanism includes a cylinder 15, which is connected to the upper slider 7 via a fixing clamp 14. A traction shaft 18 is connected to the output end of the cylinder 15. The traction shaft 18 and the extension end of the cylinder 15 are perpendicular to each other. The flaw detection column 12 is rotatably connected to the traction shaft 18. A deflection shaft 19 is rotatably connected to the flaw detection column 12. One end of the deflection shaft 19 is connected to the lower slider 11, which is slidably connected to the X-slide shaft 5. When adjusting the orientation angle of the flaw detection column 12, the horizontal sliding range of the upper slider 7 and the vertical extension length of the cylinder 15 are both the rotation diameter of the flaw detection column 12.

[0027] Specifically, such as Figure 2 As shown, a bottom groove 8 is provided at the lower end of the X-axis 5, and the lower slider 11 is slidably connected to the bottom groove 8. The bottom groove 8 is provided to improve the sliding stability of the lower slider 11.

[0028] Specifically, such as Figure 2 As shown, a limiting rod 9 is connected to the bottom slide groove 8, and the lower slide block 11 is slidably connected to the limiting rod 9. Springs 10 are symmetrically connected to the outside of the lower slide block 11. The springs 10 are sleeved on the limiting rod 9. The limiting rod 9 is used to limit the structure of the lower slide block 11. The structure of the limiting rod 9 passes through the lower slide block 11. Under the action of the spring 10, the lower slide block 11 is located in the middle position of the limiting rod 9.

[0029] In summary, the X-ray non-destructive testing device for industrial steel structures provided in this embodiment allows the industrial steel structure to be placed on a rotating disk 2 during flaw detection. The rotating disk 2 is then rotated to a suitable angle, and the motor 16 and cylinder 15 are controlled to rotate, thereby driving the flaw detection column 12 to rotate around the deflection axis 19. After adjustment, the cylinder 15 is controlled to stop extending and retracting and maintain the current extension length. Then, the motor 16 is controlled to operate, which can drive the flaw detection column 12 to move along the X-axis 5. At this time, the spring 10 on one side of the lower slider 11 is compressed and the other side is stretched, controlling the vertical frame 4 to slide on the Y-axis 3, thereby realizing the flaw detection operation of the entire steel structure. During flaw detection, shielding material needs to be set on the outside of the device to avoid the X-rays from causing harm to the operators and the environment.

[0030] The orientation angle of the flaw detection column 12 can be changed by the operation of cylinder 15 and motor 16, thereby achieving the flaw detection requirements of angle. It can perform flaw detection operations on steel structures of various shapes, improving the diversity of flaw detection. It is a special equipment for non-destructive testing of the internal quality of steel structures by utilizing the penetrating power of X-rays and the attenuation characteristics of materials. It can effectively detect internal defects such as cracks, pores, slag inclusions, and incomplete penetration without damaging the steel structure workpiece. It is widely used in the quality control of steel structure manufacturing, installation and operation and maintenance in the fields of construction, bridges, pressure vessels, and engineering machinery.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
