Technical Field

[0001] This invention relates to the field of X-ray detection technology, and in particular to an X-ray detection device based on automated CR technology. Background Technology

[0002] X-ray inspection is a common non-destructive testing method used for materials, components, and structures. It utilizes X-rays to penetrate objects and detect defects based on the absorption characteristics of different materials. X-ray technology can detect internal defects in materials, such as cracks, pores, poor welds, and corrosion, and has wide applications in various fields, including industry, medicine, and scientific research.

[0003] In the prior art, document CN118243708A discloses a fixing device based on an X-ray weld inspection equipment for steel structures. Compared with existing weld inspection devices, this device can more comprehensively inspect the quality of welds. Its matching fixing device ensures that the steel pipe is stably positioned on the inspection device, and the two work together to further improve the accuracy of X-ray weld inspection.

[0004] However, while existing technologies can achieve fixed inspection of steel pipes, their fixing devices cannot adequately adapt to the irregular shapes of welded joints, such as tee fittings.

A universal joint B is rotatably connected to the movable frame, a worm gear is fixedly connected to one end of the universal joint B, and a transmission rod is fixedly connected to the other end of the universal joint B. A transmission groove is formed on the outer wall of the transmission rod, and the transmission groove consists of a spiral and a straight section.

[0011] Preferably, a worm gear is fixedly connected to one end of the tilting frame, the worm gear meshes with a worm for transmission, multiple snap-fit ​​sleeves are fixedly connected to the tilting frame, and a CR imaging plate is fixedly connected to the tilting frame.

[0012] Preferably, both sides of one end of the tee connector are fixedly connected to a snap-fit ​​connector, and a snap-fit ​​block is slidably fitted on the inner wall of one side of the snap-fit ​​connector.

The outer walls of the snap-fit ​​connector and the snap-fit ​​block are movably inserted into the snap-fit ​​sleeve. The tee connector has a limiting groove, and a matching tee connector is placed in the limiting groove.

[0013] Preferably, a threaded rod is rotatably connected to the inner wall of the fixed column, and a motor is fixedly connected to the bottom end of the threaded rod, with the motor being fixedly connected to the fixed column.

[0014] Preferably, a slider is fixedly connected to one end of the detection cover, one end of the slider is threadedly connected to a threaded rod, a toothed rod is fixedly connected to the bottom end of the slider, a plurality of transmission teeth are rotatably connected to the inner wall of the bottom end of the toothed rod, a tension spring is fixedly connected to one end of the transmission teeth, the other end of the tension spring is fixedly connected to the inner wall of the toothed rod, the transmission teeth mesh with a transmission wheel, a lead layer is fixedly connected to the inner wall of the detection cover, and a high-pressure X-ray tube is fixedly connected to the upper inner wall of the detection cover.

The detachable tee fitting seat design allows for replacement according to tee fittings of different sizes and shapes, increasing the adaptability of the equipment.

[0018] 2. By setting up a detection hood and installing a lead layer on the inner wall of the hood, X-ray radiation can be effectively shielded, preventing workers from being exposed to radiation and ensuring operator safety. When the detection hood moves upward, it drives the rotating base to rotate intermittently, allowing the equipment to switch between workpieces more quickly, thereby reducing workpiece processing time. The automated design improves the equipment's working efficiency.

[0019] 3. By setting up a moving frame, a tilting frame, and a feeding frame, the T-connectors on the T-connector seat are automatically fed, significantly reducing manual intervention and automating the feeding process. This not only improves production efficiency but also reduces the possibility of human error. Simultaneously, the buffer plate on the feeding frame effectively slows down the falling speed of the T-connectors, preventing collisions or damage during feeding, ensuring the integrity and quality of the T-connectors, improving the finished product pass rate, and reducing the defective product rate.

[0030] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0031] like Figures 1-9 The X-ray inspection device based on automated CR technology shown includes a base 1, a rotating seat 2 above the base 1, multiple movable frames 3 slidably mounted on the rotating seat 2, a flipping frame 4 rotatably connected to the movable frame 3, a three-way connector seat 5 mounted on the flipping frame 4, a fixed column 6 fixedly connected to one side of the base 1, an inspection cover 7 slidably mounted on the fixed column 6, and a feeding rack 8 fixedly connected to one side of the base 1.

[0032] like Figure 3 As shown, a fixed frame 101 is fixedly connected to the base 1, and a ring frame 102 is fixedly connected to the fixed frame 101. A guide groove 103 is provided on the top surface of the ring frame 102. The guide groove 103 is located on one side of the unloading rack 8 and is arranged in a protruding structure.

[0033] like Figure 4As shown, a universal joint A201 is fixedly connected to the bottom end of the rotating seat 2. The universal joint A201 is rotatably connected to the fixed frame 101, and a transmission wheel 202 is fixedly connected to the other end of the universal joint A201. When the detection cover 7 moves upward beyond the tee joint 504, the transmission teeth 703 on the rack 702, under the action of the tension spring 704, will drive the transmission wheel 202 to rotate, causing the transmission wheel 202 to drive the rotating seat 2 connected to the universal joint A201 to rotate.

[0034] like Figure 5 As shown, a guide rod 301 is fixedly connected to the bottom of the movable frame 3. The other end of the guide rod 301 is slidably engaged with the inner wall of the guide groove 103. A universal joint B302 is rotatably connected to the movable frame 3. A worm gear 303 is fixedly connected to one end of the universal joint B302, and a transmission rod 304 is fixedly connected to the other end of the universal joint B302. A transmission groove 305 is opened on the outer wall of the transmission rod 304. The transmission groove 305 is composed of a spiral and a straight part. A fixed head 306 is slidably engaged with the inner wall of the transmission groove 305. The fixed head 306 is fixedly connected to the rotating seat 2. The guide rod 301 at the bottom of the movable frame 3 will move to the protruding position of the guide groove 103, thereby driving the movable frame 3 to move. Then, when the helical position of the transmission groove 305 on the transmission rod 304 contacts the fixed head 306, it will drive the transmission rod 304 to rotate, so that the transmission rod 304 drives the worm gear 303 connected to the universal joint B302 to rotate, so that the worm gear 303 can drive the tilting frame 4 connected to the worm wheel 401 to tilt.

[0035] like Figure 6 As shown, a worm gear 401 is fixedly connected to one end of the tilting frame 4. The worm gear 401 meshes with the worm 303 for transmission. Multiple snap-fit ​​sleeves 402 are fixedly connected to the tilting frame 4. A CR image plate is fixedly connected to the tilting frame 4.

[0036] like Figure 7 As shown, a snap-fit ​​connector 501 is fixedly connected to both sides of one end of the tee connector base 5. A snap-fit ​​block 502 is slidably fitted onto the inner wall of one side of the snap-fit ​​connector 501. A spring A503 is fixedly connected to the inner end of the snap-fit ​​block 502. The other end of the spring A503 is fixedly connected to the inner wall of the snap-fit ​​connector 501. The outer walls of the snap-fit ​​connector 501 and the snap-fit ​​block 502 are movably inserted into the snap-fit ​​sleeve 402. The tee connector base 5 has a limiting groove, in which a matching tee connector 504 is placed. The outer end of the snap-fit ​​connector 501 has a bevel for easy and quick insertion into the snap-fit ​​sleeve 402. When the snap-fit ​​connector 501 at the bottom of the tee connector base 5 is inserted into the snap-fit ​​sleeve 402 in the appropriate position, the snap-fit ​​block 502 is inserted into the snap-fit ​​sleeve 402 under the action of the spring A503, thus fixing the tee connector base 5 onto the flip frame 4.

[0037] By creating a limiting groove on the tee connector seat 5 that matches the shape of the tee connector 504, the limiting groove can precisely match the shape of the tee connector 504, ensuring more stable fixation and positioning of the connector during the inspection process. This effectively prevents displacement of the tee connector 504 during X-ray inspection, ensuring the accuracy of the weld position during inspection and avoiding inspection errors caused by unstable positioning. The detachable tee connector seat 5 design allows for replacement according to different sizes and shapes of tee connectors 504, increasing the adaptability of the equipment.

[0038] like Figure 8 As shown, a threaded rod 601 is rotatably connected to the inner wall of the fixed column 6, and a motor 602 is fixedly connected to the bottom end of the threaded rod 601. The motor 602 is fixedly connected to the fixed column 6. The tee connector 504 is placed on the tee connector seat 5, and then the motor 602 drives the connected threaded rod 601 to rotate, so that the threaded rod 601 drives the detection cover 7 connected to the slider 701 to move down.

[0039] like Figure 8 As shown, a slider 701 is fixedly connected to one end of the detection cover 7. One end of the slider 701 is threadedly connected to a threaded rod 601. A gear 702 is fixedly connected to the bottom end of the slider 701. Multiple transmission teeth 703 are rotatably connected to the inner wall of the bottom end of the gear 702. A tension spring 704 is fixedly connected to one end of each transmission tooth 703. The other end of the tension spring 704 is fixedly connected to the inner wall of the gear 702. The transmission teeth 703 mesh with a transmission wheel 202 for transmission. A lead layer is fixedly connected to the inner wall of the detection cover 7. A high-pressure X-ray tube 705 is fixedly connected to the upper inner wall of the detection cover 7. The high-pressure X-ray tube 705 is a Varian 8850, mainly used in non-destructive testing, welding quality inspection, material analysis, and other fields, and typically has high stability and durability. The lead layer on the inner wall of the detection cover 7 is a high-density material with good radiation shielding capabilities, which can isolate the radiation source from the operating area. X-rays are generated using a high-pressure X-ray tube 705. A CR imaging board receives the X-ray images after they pass through the tee connector 504. The system analyzes the images and performs analysis and inspection on the weld seam of the tee connector 504.

[0040] like Figure 9As shown, a buffer plate 801 is rotatably connected to the unloading rack 8. A rubber pad is fixedly connected to the top surface of the buffer plate 801. Two connecting rods 802 are rotatably connected to the bottom surface of the buffer plate 801 in a symmetrical structure. A U-shaped frame 803 is slidably fitted onto the unloading rack 8. The U-shaped frame 803 is rotatably connected to the connecting rods 802. Multiple springs B804 are fixedly connected to one side of the U-shaped frame 803, and the other end of the springs B804 is fixedly connected to the unloading rack 8. When the buffer plate 801 rotates, it buffers the unloading of the tee connector 504. After the tee connector 504 falls off the buffer plate 801, the springs B804 cause the U-shaped frame 803 to drive the buffer plate 801 connected to the connecting rods 802 to return to its original position.

[0041] Working principle: When X-ray inspection is required on the weld of the tee connector 504, first install the matching tee connector seat 5 onto the flip frame 4 according to the size of the tee connector 504, insert the snap-fit ​​connector 501 at the bottom of the tee connector seat 5 into the snap-fit ​​sleeve 402 in the appropriate position, and then, under the action of the spring A503, the snap-fit ​​block 502 is inserted into the snap-fit ​​sleeve 402, so that the tee connector seat 5 is installed and fixed on the flip frame 4;

[0042] Then, the tee connector 504 is placed on the tee connector seat 5, and the motor 602 drives the connected threaded rod 601 to rotate, so that the threaded rod 601 drives the detection cover 7 connected to the slider 701 to move down, so that the bottom end of the detection cover 7 is in close contact with the rotating seat 2. Then, the high-pressure X-ray tube 705 generates X-rays, and the CR imaging board receives the X-ray image after passing through the tee connector 504. The system analyzes the image and analyzes and detects the weld of the tee connector 504.

[0043] After the inspection is completed, when the inspection cover 7 moves up past the tee connector 504, the transmission gear 703 on the rack 702 will drive the transmission wheel 202 to rotate under the action of the tension spring 704. This will cause the transmission wheel 202 to drive the rotating seat 2 connected to the universal joint A201 to rotate, so that the inspected tee connector 504 will rotate to one side of the unloading rack 8.

[0044] At this time, the guide rod 301 at the bottom of the movable frame 3 will move to the protruding position of the guide groove 103, thereby driving the movable frame 3 to move. Then, when the spiral position of the transmission groove 305 on the transmission rod 304 contacts the fixed head 306, it will drive the transmission rod 304 to rotate, causing the transmission rod 304 to drive the worm gear 303 connected to the universal joint B302 to rotate, so that the worm gear 303 can drive the flipping frame 4 connected to the worm wheel 401 to flip, so that the tee connector 504 on the tee connector seat 5 can fall onto the buffer plate 801. Then the buffer plate 801 will rotate to buffer the tee connector 504. After the tee connector 504 falls off the buffer plate 801, under the action of the spring B804, the U-shaped frame 803 will drive the buffer plate 801 connected to the connecting rod 802 to reset.
