Description

Technical Field

[0001] This utility model relates to a device for circumferential X-ray inspection, belonging to the field of nondestructive testing technology. Background Technology

[0002] Currently, radiographic testing is an important method in industrial non-destructive testing. Using film as the recording medium, it provides direct, visual images of defects, which can be stored and traced long-term. It is suitable for inspecting pipe weld joints and achieves good results. However, in field inspections, most pipes are large-diameter and installed at high altitudes, causing significant inconvenience. Typically, radiographic testing of weld joints in these areas is performed using gamma radiation sources. However, due to strict management and complex registration procedures for gamma radiation sources, as well as high safety risks, they cannot be introduced in power plants, maintenance areas, or areas with strict safety management. In most cases, pipe radiographic testing must be performed using a dedicated X-ray machine. Most pipes in the field use double-wall single-image imaging, requiring a large transmission thickness and high-energy X-ray machine operating voltage, generally requiring a 250-type or higher model. Because these machines are large and heavy (30-40 catties each), moving them during inspection is quite strenuous. When inspecting pipes at high altitudes or after installation using X-ray machines, circumferential welded joints must be inspected without missing any. This requires the X-ray machine to be moved and adjusted 360° circumferentially. Currently used X-ray machines lack effective portable devices, requiring manual on-site fixing and simple support structures for adjustment. This results in slow work efficiency and difficulty in securing the X-ray machine. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a circumferentially movable X-ray machine inspection device that addresses the shortcomings of the existing technology. This device can effectively fix the X-ray machine, facilitate circumferential movement, and reduce labor intensity.

[0004] To solve this technical problem, this utility model provides a circumferentially movable X-ray inspection device, including a support fixing device, a sliding device, a limiting device, and an X-ray device. Two identical support fixing devices are arranged side-by-side. Each support fixing device includes an upper support ring, a lower support ring, a connecting rod, a supporting rod, and a magnetic chuck. The sliding device is connected to the left support fixing device via the connecting rod, and the limiting device is connected to the right support fixing device via the connecting rod. The magnetic chuck is connected to both the upper and lower support rings via the supporting rods. The support fixing device is fixed to the pipe by magnetic adsorption. The X-ray device includes a left sliding block, a right sliding block, and an X-ray machine. The left sliding block is embedded in the sliding device, and the right sliding block is embedded in the limiting device. The X-ray machine is connected to both the left and right sliding blocks via support legs. The X-ray machine can move 360° circumferentially to perform X-ray inspection of welds.

[0005] The bracket fixing device also includes connecting bolts. The upper support ring interface is concave, and the lower support ring interface is convex. The upper support ring and the lower support ring are connected and fixed by connecting bolts.

[0006] The sliding device includes a fixed hook, a sliding groove, a fixed nail, and a sliding ring. The sliding ring is composed of two parts spliced ​​together and connected to the fixed nail by the fixed hook. The connecting rod is connected to the sliding ring.

[0007] The sliding ring is provided with a sliding groove, and the ray device slides circumferentially within the sliding groove.

[0008] The limiting device includes a limiting ring, a limiting pin, a limiting hole, and a limiting groove. The limiting ring is composed of two parts spliced ​​together. Twenty-four limiting holes are evenly distributed around the perimeter of the limiting ring. Limiting pins are inserted into the limiting holes to limit the position of the X-ray machine.

[0009] The limiting ring is provided with a limiting groove. The X-ray device moves within the limiting groove. After moving to a suitable detection position, it is fixed by a limiting pin to prevent the X-ray machine from sliding.

[0010] The left sliding block is embedded in the sliding groove of the sliding device, and the right sliding block is embedded in the limiting groove of the limiting device.

[0011] The X-ray device also includes an emission window through which the X-ray machine emits X-rays to complete the X-ray inspection of the welds on the pipeline to be inspected.

[0012] Beneficial Effects: This utility model is a convenient and efficient X-ray inspection device. By using a circumferentially moving X-ray machine, it can perform X-ray inspection of pipe welds at high altitudes. The device is assembled using a support fixing device, a sliding device, a limiting device, and the X-ray machine itself. In this utility model, the support fixing device is attached to the pipe to be inspected by eight magnetic chucks. The magnetic chucks are controlled by a knob switch to open and close the magnetism, thus fixing and attaching the entire device. During X-ray inspection, the moving X-ray machine slides circumferentially within the sliding groove and limiting groove. After rotating to the inspection position, the limiting pin is inserted into the limiting hole to fix the X-ray machine at the inspection position, completing the weld inspection at that location. After the inspection is completed, the limiting pin is removed, and the moving X-ray machine rotates to the next position to continue the inspection until the entire weld circumferentially inspected 360°. This invention is applicable to radiographic inspection of welds in restricted or high-altitude locations. Inspectors can efficiently and conveniently complete the circumferential inspection of the entire weld without having to set up a separate inspection support. This reduces the need for construction preparation, lowers the labor intensity of inspectors, reduces the safety risks to personnel during the inspection process, improves inspection efficiency, and ensures the quality of on-site pipeline inspection.

The magnetic suction cup 15...

The X-ray machine 43 can move 360° circumferentially and can efficiently complete the X-ray inspection of weld B.

[0026] The bracket fixing device 1 also includes a connecting bolt 16. The interface of the upper support ring 11 is concave, and the interface of the lower support ring 14 is convex. The upper support ring 11 and the lower support ring 14 are connected and fixed by the connecting bolt 16.

[0027] The sliding device 2 includes a fixed hook 21, a sliding groove 22, a fixed nail 23, and a sliding ring 24. The sliding ring 24 is composed of two parts spliced ​​together. After the fixed hook 21 is rotated, it is fixedly stuck on the fixed nail 23. The connecting rod 12 is connected to the sliding ring 24.

[0028] The sliding ring 24 is provided with a sliding groove 22, and the ray device 4 slides circumferentially within the sliding groove 22.

[0029] The limiting device 3 includes a limiting ring 31, a limiting pin 32, a limiting hole 33, and a limiting groove 34. The limiting ring 31 is composed of two parts spliced ​​together. Twenty-four limiting holes 33 are evenly distributed around the perimeter of the limiting ring 31. The limiting pin 32 is inserted into the limiting hole 33 to limit the position of the X-ray machine 43.

[0030] The limiting ring 31 has a limiting groove 34 on its inner side. The X-ray device 4 moves in the limiting groove 34. After moving to a suitable detection position, it is fixed by the limiting pin 32 to prevent the X-ray machine 43 from sliding.

The bracket fixing device 1, the sliding device 2, and the limiting device 3 are assembled together. The magnetic switch of the magnetic chuck 15 is turned on, so that the bracket fixing device 1 is fixed on the pipe A to be inspected. The X-ray machine 43 is moved circumferentially. When it moves to the inspection position, the limiting pin 32 is inserted into the limiting hole 33 to lock the right sliding block 42 in the X-ray device 4 and the inspection begins. After the inspection at this position is completed, the limiting pin 32 is pulled out, and the X-ray machine 43 is moved circumferentially to the next inspection position. The limiting pin 32 is then inserted into the limiting hole 33 to complete the inspection at this position. This process is repeated until the inspection of the entire weld B is completed.

The machine is assembled using a support fixing device, a sliding device, a limiting device, and the X-ray device itself. In this invention, the support fixing device is attached to the pipeline A to be inspected by eight magnetic chucks. The magnetic chucks are controlled by a knob switch to maintain their magnetism, thus fixing and attaching the entire device. During X-ray inspection, the moving X-ray device slides circumferentially within the sliding and limiting grooves. After rotating to the inspection position, the limiting pin is inserted into the limiting hole to fix the X-ray machine at that position, completing the weld inspection at that location. After inspection, the limiting pin is removed, and the moving X-ray machine rotates to the next position to continue the inspection until the entire weld circumferentially inspected 360°. This invention is applicable to radiographic inspection of welds in restricted or high-altitude locations. Inspectors can efficiently and conveniently complete the circumferential inspection of the entire weld without having to set up a separate inspection support. This reduces the need for construction preparation, saves time and costs associated with setting up the inspection platform, reduces the labor intensity of inspectors, lowers the safety risks to personnel and the risk of equipment damage during the inspection process, improves inspection efficiency, and ensures the quality of on-site pipeline inspection.
