Description

Technical Field

[0001] This utility model relates to the field of DR detection technology, specifically to an angle-adjustable DR detection device. Background Technology

[0002] X-rays are invisible electromagnetic radiation with high penetrating power, capable of passing through the human body and objects. When X-rays pass through an object, they are absorbed or scattered, leading to the visualization of the object's internal structure and defects. Based on this principle, industrial DR (Digital Radiography) inspection equipment has emerged. The detector is a key component of industrial DR equipment, converting X-rays into electrical signals and transmitting them to the processing unit for further processing. The detector typically consists of a scintillation crystal and a photomultiplier tube. When X-rays strike the scintillation crystal, they are converted into visible light. The photomultiplier tube then converts this light into electrical signals, which are further processed by external image processing equipment. The data is processed and converted into image data, which is commonly used in the field of pipeline flaw detection. When existing industrial DR inspection equipment performs pipeline flaw detection, the detector is mostly manually held to perform flaw detection work in different areas of the pipeline. The operator holds the detector, points it at the pipeline, and then slowly moves and deflects the detector to achieve flaw detection work at different positions and angles of the pipeline. The detector of traditional industrial DR inspection equipment is manually held, and the distance and angle between the detector and the pipeline cannot be kept consistent during use, which affects the flaw detection effect. Different sizes of detectors have different weights. If the detector is too heavy, it will be a heavy burden for the operator to hold. Therefore, we propose an angle-adjustable DR inspection device.

It can automatically adjust to multiple angles, perform detection work at eight accurate angles, and also perform detection work at free angles. It is suitable for flaw detection work on pipes of different heights and sizes.

[0025] The working principle of the DR inspection device with adjustable angle provided by this utility model is as follows: When using the DR inspection device for pipeline flaw detection, firstly, the column 1 is fixed to the external transport platform through the bolt hole 4. Then, the RD detector 34 is installed and placed in front of the mounting bracket 331. Then, the knob 336 is turned to drive the bevel gear 335 to rotate. As the bevel gear 335 rotates, the four bevel gears 334 also rotate, driving the corresponding lead screw 332 to rotate. The clamping block 333 moves inward synchronously and then contacts the edge of the RD detector 34, forming a clamping effect on the RD detector 34. Then, the RD detector 34 is connected to the external image display device. When it is necessary to inspect the area directly below the pipeline, the microcontroller 5 controls the motor. When motor 323 operates, its output shaft drives worm gear 324 to rotate. When worm gear 324 rotates clockwise, worm wheel 322 meshes with it, causing it to rotate as well. This rotates deflection arm 321 upwards until the RD detector 34 is parallel to the lifting arm 2. At this point, height adjustment is performed based on the pipe's dimensions and height. Microcontroller 5 controls motor 36 to operate, and its output shaft drives lead screw 31 to rotate. When lead screw 31 rotates clockwise, lifting arm 2 moves upwards; when it rotates counterclockwise, lifting arm 2 moves downwards until the RD detector 34 reaches the appropriate detection height. Then, the external transport platform is moved to position the RD detector 34 directly below the pipe. Microcontroller 5 controls the operation of the RD detector 34. The external image display device clearly shows the defects inside the pipe. Then, a 45-degree inspection is performed on the lower left side of the pipe. The external transport platform moves the column 1 to the left to the appropriate position. The microcontroller 5 continues to control the operation of motor 323. Through the meshing of worm gear 322 and worm 324, the deflection arm 321 deflects upward by 45 degrees to perform a 45-degree inspection on the lower left side of the pipe. Then, a 45-degree inspection is performed on the lower right side of the pipe. Motor 36 first drives the lifting arm 2 to move downward. Motor 323 rotates, causing the deflection arm 321 to continue rotating 90 degrees. Then, the microcontroller 5 controls motor 35 to operate. Motor 35 drives the mounting bracket 331 to rotate 180 degrees, so that the RD detector 34 completes the flip and is aligned with the lower right side of the pipe. Motor 36 then drives the lifting arm 2 to move downward. The lifting arm 2 moves upward until the RD detector 34 reaches the appropriate detection position, performing a 45-degree detection at the lower right of the pipeline, followed by a 45-degree detection at the upper right of the pipeline. The external transport platform moves to the right, the deflection arm 321 reverses 90 degrees, the lifting arm 2 moves upward, and the external transport platform moves to the left until the RD detector 34 reaches the appropriate detection position, performing a 45-degree detection at the upper right of the pipeline, followed by a detection directly above the pipeline. The lifting arm 2 moves upward to the appropriate position, the deflection arm 321 reverses 45 degrees, and the RD detector 34 is parallel to the lifting arm 2, performing a detection directly above the pipeline. Then, motor 2 35 reverses, driving the mounting bracket 331 to rotate 180 degrees, the deflection arm 321 reverses 45 degrees, and the RD detector 34 is aligned with the upper left of the pipeline.For inspection of the pipeline at a 45-degree angle to the upper left, the coordinated operation of motors 323 (Motor 1), 35 (Motor 2), and 36 (Motor 3) allows for flaw detection at eight specified angles, as well as at free angles.

[0026] It is worth noting that the microcontroller 6 disclosed in the above embodiments is an S7-200 microcontroller, motor 323 is a QCAVS-QCAVP motor, RD detector 34 is an HPX-DR 2530 compact detector, motor 35 is a 57BYGH601-05AG6 motor, and motor 36 is a 1FK7042-2AF71-1UB0 motor. The microcontroller 6 controls the operation of motor 323, RD detector 34, motor 35, and motor 36 using methods commonly used in the prior art.
