Technical Field

[0001] This utility model relates to the field of nondestructive testing technology, and in particular to a device for X-ray inspection of circumferential welds of pipes of different diameters. Background Technology

[0002] Non-destructive testing (NDT) technology, as a key means to ensure the safe operation of industrial equipment, plays an important role in the internal quality inspection of stressed components in many fields such as manufacturing and energy. Among various NDT technologies, X-ray inspection technology occupies an important position with its significant advantages. It is not only fast and efficient in inspection, enabling real-time detection and recording, but also able to intuitively and accurately judge the defect morphology of welds and other parts. Therefore, it is widely used in the manufacturing quality inspection and in-service safety verification of key equipment such as power plant boilers, steam and water pipelines, and pressure vessels, and is especially suitable for defect detection of welds in various fusion welding joints.

[0003] Current X-ray inspection equipment for pipeline circumferential welds still has the following problems:

[0004] 1. The structural design of some pipe circumferential weld X-ray inspection devices has limitations. They are limited to the inspection of only one type of pipe and cannot be flexibly adapted to pipes of different diameters, which significantly restricts their application range and fails to meet diverse inspection needs.

[0005] 2. The fixing device inside the X-ray inspection equipment for some pipeline circumferential welds is unstable in fixing the pipeline, which causes the device to shake or shift, resulting in changes in X-ray parameters, causing blurred images, misjudgment of defects or missed detection, seriously affecting the reliability of the inspection results and creating hidden dangers for inspection safety. Utility Model Content

This addresses the limitations of existing X-ray inspection devices for circumferential welds, which have structural design limitations, are restricted to inspecting only one type of pipe, and are difficult to adapt flexibly to pipes of different diameters. This significantly limits their application range, fails to meet diverse inspection needs, and causes instability in the fixing device, leading to device shaking or displacement, changes in X-ray parameters, blurred images, misjudgment of defects, or missed detections. These issues seriously affect the reliability of inspection results and create potential safety hazards.

[0007] To achieve the above objectives, an apparatus for X-ray inspection of circumferential welds of pipes of different diameters is provided, comprising a fixed ring, a slot I is provided inside the fixed ring, a gear disk II is rotatably mounted inside the slot I, a plurality of gears I are meshed at the outer end of the gear disk II, the plurality of gears I and the gear disk II are all arranged in the slot I, a rotating rod is fixedly mounted on each of the plurality of gears I, and a bevel gear I is fixedly mounted on each of the rotating rods;

[0012] According to the device for X-ray inspection of circumferential welds of pipes of different diameters, a second gear is meshed at the outer end of the first gear disk, and the second gear is located outside the first slot.

[0013] According to the device for X-ray inspection of circumferential welds of pipes of different diameters, a motor is fixedly installed at the bottom of the fixed ring, and the output end of the motor passes through the fixed ring and is connected to one end of a gear through a coupling.

[0029] 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.

[0030] Reference Figure 1-6 This utility model discloses an X-ray inspection device for circumferential welds of pipes of different diameters. The device includes a fixed ring 1, with a slot 9 inside. A gear disk 10 is rotatably mounted inside the slot 9. Several gears 11 mesh with the outer ends of the gear disk 10. Both the gears 11 and the gear disk 10 are located within the slot 9. Rotating rods 19 are fixedly mounted on each of the gears 11, and bevel gears 12 are fixedly mounted on each of the rotating rods 19. Several rotating columns 15 are rotatably mounted around the perimeter of the slot 9. Bevel gears 14 are fixedly mounted in the middle of each of the rotating columns 15, meshing with the outer ends of the bevel gears 12. Baffles 13 are fixedly mounted at the ends of each of the rotating columns 15, and the baffles 13 are located at the bevel gears 14. Subsequently, by setting baffle 13, the fixed block 5 is prevented from directly hitting bevel gear 14 when it moves backward. A screw rod 16 is fixedly installed on the middle of one side of baffle 13. In use, the motor 20 drives a gear 11 to rotate, which in turn drives the rotating column 15 and bevel gear 12 fixedly installed on the upper end of gear 11 to rotate. The rotation of bevel gear 12 drives the meshing bevel gear 14 to rotate, which in turn drives the rotating column 15 and screw rod 16 to rotate. This causes the fixed block 5, which is fitted on the screw rod 16, to reciprocate linearly. This allows the fixed plate 6 and elastic pad 7 to stably fix pipes of different diameters, avoiding changes in X-ray parameters caused by device shaking or displacement, which could lead to blurred imaging, misjudgment of defects, or missed detection.

[0031] Each lead screw 16 is fitted with a fixing block 5, and each fixing block 5 has a baffle 17 fixedly installed at its end. By setting the baffle 17, the fixing block 5 is prevented from falling off the lead screw 16 when it moves forward. Each fixing block 5 has a fixing plate 6 fixedly installed at its front end through the fixing ring 1. Each fixing plate 6 has an elastic pad 7 at its outer end. A slide rail 8 is fixedly installed at the bottom of the fixing ring 1. A gear disk 2 is slidably installed on the slide rail 8. A gear 18 is meshed at the outer end of the gear disk 2. The gear 18 is located outside the slot 9. A motor 20 is fixedly installed at the bottom of the fixing ring 1. The output end of the motor 20 passes through the fixing ring 1 and extends outward. The inner end of the gear is connected to one end of a gear 11 via a coupling. The bottom of the fixing ring 1 is fixedly installed on one side of the motor 20, and the output end of the motor 21 is also connected to one end of the gear 18 via a coupling through the fixing ring 1. An arc plate 3 is fixedly installed on the outer end of the gear disk 2, and an X-ray machine 4 is set at the bottom end of the arc plate 3. In use, after the pipeline is stably fixed, the motor 21 is started to drive the gear 18 to rotate. The rotation of the gear 18 drives the meshing gear disk 2 to rotate, thereby driving the fixing plate 6 and the X-ray machine 4 to rotate, thus performing a 360-degree inspection of the pipeline.

[0032] Working principle: When a device for X-ray inspection of circumferential welds of pipes of different diameters is put into use, the starting motor 20 drives a gear 11 to rotate, which in turn drives the rotating column 15 and bevel gear 12 fixed on the upper end of the gear 11 to rotate. The rotation of the bevel gear 12 drives the meshing bevel gear 14 to rotate, which in turn drives the rotating column 15 and the lead screw 16 to rotate, which in turn drives the fixed block 5, which is fitted on the lead screw 16, to reciprocate linearly. This allows the fixing plate 6 and the elastic pad 7 to stably fix the pipes of different diameters. After the pipes are stably fixed, the starting motor 21 drives a gear 18 to rotate. The rotation of the gear 18 drives the meshing gear disc 2 to rotate, which in turn drives the fixing plate 6 and the X-ray machine 4 to rotate, thus performing 360-degree inspection of the pipes.

[0033] 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.
