Description

Technical Field

[0001] This utility model belongs to the technical field of TOFD simulation test blocks, and particularly relates to turnover equipment for TOFD simulation test blocks in nondestructive testing. Background Technology

[0002] TOFD simulation test blocks are specialized standard parts used for experimental verification, personnel training, and equipment debugging in ultrasonic diffraction time-of-flight testing technology. Their core function is to quantitatively verify the detection capability by pre-setting artificial defects. The base material is mostly carbon steel such as 45# steel, and some contain alloy steel weld overlay. The surface is processed with artificial cracks, pores, and other defects with a width of 0.2mm according to the testing requirements. In industrial scenarios, it is used to verify the feasibility of testing processes such as PE pipe welds, as a training carrier for testing personnel to identify defect signals, and can also assist in debugging parameters such as equipment gain and scanning speed.

[0003] Currently, TOFD simulation test blocks mainly rely on trolleys for turnover. However, due to the characteristics of the test blocks and the design flaws of the equipment, there are obvious shortcomings. On the one hand, the test blocks vary greatly in weight and their surfaces are mostly smooth metal surfaces. The trolleys lack limiting mechanisms to adapt to different specifications, and they are prone to offset and slippage due to inertia during transportation. On the other hand, the trolleys are not equipped with shock absorption structures, and the artificial cracks and other defects of the test blocks are sensitive to vibration. The vertical vibration caused by uneven ground during transportation will cause micro-damage to the defect edges, affecting the accuracy of subsequent detection signals. Therefore, to solve the above problems, we provide a turnover device for TOFD simulation test blocks in non-destructive testing. Summary of the Invention

[0004] To address the above-mentioned technical problems, this utility model proposes a turnover device for TOFD simulation test blocks in nondestructive testing, thereby solving at least one of the problems mentioned in the background art.

[0005] The technical solution of this utility model is: This utility model proposes a turnover device for TOFD simulation test blocks in non-destructive testing, including a movable base plate. Movable buffer components are fixedly embedded on both sides of the movable base plate. A positioning plate is fixedly installed on the top of both movable buffer components. A placement tray is snapped onto the upper surface of the positioning plate. A support slide is fixedly installed on one side of the movable base plate. A driving component is provided on one side of the support slide. A lifting slide cover is slidably connected to the inner wall of the support slide. A threaded transmission plate is fixedly installed on the inner wall of the lifting slide cover. A threaded transmission rod is threadedly connected to the inner wall of the threaded transmission plate. A connecting block is fixedly connected to one side of the lifting slide cover. A fixing pressure plate is fixedly connected to one side of the connecting block. A movable pusher is fixedly connected to the outer surface of the support slide.

[0006] Preferably, the driving component includes a bearing ring fixedly embedded in one side of a supporting slide, a rotating rod fixedly connected to the inner ring of the bearing ring, a driving gear fixedly installed at one end of the rotating rod, a bearing seat fixedly installed on the inner wall of the supporting slide, the inner ring of the bearing seat fixedly installed to the bottom end of a threaded transmission rod, a transmission gear fixedly installed at the bottom end of the threaded transmission rod, and one end of the transmission gear meshing with the top end of the driving gear.

[0007] Preferably, a limiting hole is provided on one side of the supporting slide, a limiting block is fixedly connected to one side of the lifting slide cover, the outer surface of the limiting block is slidably connected to the inner wall of the limiting hole, two limiting slides are fixedly connected to the outer surface of the movable base plate, the inner walls of the two limiting slides are slidably connected to limiting slide plates, and the sides of the two limiting slide plates that are close to each other are fixedly connected to the outer surface of the fixed pressure plate.

[0008] Preferably, the movable buffer includes a fixed support plate fixedly installed on one side of the movable base plate. Two support covers are fixedly embedded in the inner ring of the fixed support plate. Springs are fixedly connected to the inner top walls of the two support covers. Buffer slides are fixedly connected to the bottom ends of the two springs. The outer surfaces of the buffer slides are slidably connected to the inner ring of the support covers. Universal self-locking wheels are fixedly installed at the bottom ends of the two buffer slides.

[0009] Preferably, the upper surface of the fixed pressure plate is provided with a loading groove, two elastic fixing straps are fixedly connected to the upper surface of the fixed pressure plate, and the two ends of the elastic fixing straps are fixedly connected to the upper surface of the fixed pressure plate. A silicone anti-slip layer is fixedly connected to the bottom surface of the fixed pressure plate, and the fixed pressure plate is located above the tray.

[0010] This utility model has the following advantages and effects compared with the prior art: (1) In nondestructive testing, the TOFD simulation test block turnover equipment can flexibly adjust the position of the fixed pressure plate according to the height of the test block through the linkage of the driving component and the lifting structure. After rotating the rotating rod, the threaded transmission rod can be driven to rotate through the drive gear and transmission gear, which can drive the threaded transmission plate to drive the lifting slide to slide along the support slide, so that the silicone anti-slip layer on the bottom surface of the fixed pressure plate can be tightly attached to the surface of the test block. The silicone anti-slip layer can enhance the friction to prevent the test block from sliding, and can also avoid rigid contact from causing damage to the test block.

[0011] (2) In non-destructive testing, the TOFD simulation test block turnover equipment and the moving buffer can form an efficient shock absorption structure through the combination of support cover, spring and buffer slide. When the equipment is vibrated, the spring absorbs the vibration energy through the elastic deformation of compression or stretching, and the buffer slide slides along the support cover to assist in shock absorption. It can block the vibration from being transmitted to the positioning plate and the placement tray. At the same time, the universal self-locking wheel and the moving pusher can realize labor-saving transportation and improve turnover efficiency. It also ensures that the test block is always in good condition throughout the turnover process through multiple protections, which can provide a strong guarantee for the accuracy of subsequent non-destructive testing.

[0014] To enable those skilled in the art to better understand this utility model, it will now be further described in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of this utility model.

[0015] Example 1: like Figures 1-5As shown, this utility model provides a turnover device for TOFD simulation test blocks in non-destructive testing, including a movable base plate 1. Movable buffer components 2 are fixedly embedded on both sides of the movable base plate 1. A positioning plate 3 is fixedly installed on the top of the two movable buffer components 2. A placement tray 4 is snapped onto the upper surface of the positioning plate 3. A support slide 5 is fixedly installed on one side of the movable base plate 1. A driving component 9 is provided on one side of the support slide 5. A lifting slide cover 10 is slidably connected to the inner wall of the support slide 5. A threaded transmission plate 12 is fixedly installed on the inner wall of the lifting slide cover 10. A threaded transmission rod 18 is threadedly connected to the inner wall of the threaded transmission plate 12. A connecting block 11 is fixedly connected to one side of the lifting slide cover 10. The device has a fixed pressure plate 6 and a moving pusher 17 fixedly connected to the outer surface of the supporting slide 5. Specifically, the moving buffer 2 can absorb the vibration during the equipment transfer process and reduce the impact of vibration on the test block. The positioning plate 3 is used to position the placement tray 4 to ensure the stability of the placement tray 4. The placement tray 4 directly carries the TOFD simulation test block and provides an independent placement space for the test block. The supporting slide 5 provides a sliding track for the lifting slide 10 to ensure the stable movement of the lifting slide 10. The driving component 9 provides a power source for the lifting and lowering of the lifting slide 10 to realize the position adjustment of the fixed pressure plate 6. The fixed pressure plate 6 can press down to fit the surface of the test block to fix the test block. The moving pusher 17 makes it easy for the operator to push the equipment and realize the overall movement of the equipment.

[0016] In this embodiment, the driving component 9 includes a bearing ring 91 fixedly embedded in one side of the supporting slide 5. A rotating rod 92 is fixedly connected to the inner ring of the bearing ring 91. A driving gear 93 is fixedly installed at one end of the rotating rod 92. A bearing seat 95 is fixedly installed on the inner wall of the supporting slide 5. The inner ring of the bearing seat 95 is fixedly installed to the bottom end of the threaded transmission rod 18. A transmission gear 94 is fixedly installed at the bottom end of the threaded transmission rod 18. One end of the transmission gear 94 meshes with the top end of the driving gear 93. A limiting hole 14 is opened on one side of the supporting slide 5. A limiting block 13 is fixedly connected to one side of the lifting slide cover 10. The outer surface of the limiting block 13 is slidably connected to the inner wall of the limiting hole 14. Two limiting slides 15 are fixedly connected to the outer surface of the movable base plate 1. The inner walls of both limiting slides 15 are slidably connected to... The limiting slide plates 16 are fixedly connected to the outer surface of the fixed pressure plate 6 on their sides that are close to each other. Specifically, the rotating rod 92 drives the drive gear 93 to rotate synchronously. The drive gear 93 meshes with the transmission gear 94 to transmit the power of the rotating rod 92 to the transmission gear 94. The bearing seat 95 provides rotational support for the threaded transmission rod 18 to ensure stable rotation of the threaded transmission rod 18. The threaded transmission rod 18 rotates under the drive of the transmission gear 94 and drives the lifting slide cover 10 to rise and fall through cooperation with the threaded transmission plate 12. The limiting hole 14 cooperates with the limiting block 13 to limit the sliding direction of the lifting slide cover 10 and prevent the lifting slide cover 10 from deviating. The limiting slide seat 15 provides a sliding track for the limiting slide plates 16 to limit the movement trajectory of the fixed pressure plate 6 and improve the stability of the fixed pressure plate 6 when it rises and falls.

[0017] In this embodiment, the movable buffer 2 includes a fixed support plate 21 fixedly installed on one side of the movable base plate 1. Two support covers 22 are fixedly embedded in the inner ring of the fixed support plate 21. Springs 23 are fixedly connected to the inner top walls of both support covers 22. Buffer slides 24 are fixedly connected to the bottom ends of both springs 23, and the outer surfaces of the buffer slides 24 are slidably connected to the inner ring of the support covers 22. Universal self-locking wheels 25 are fixedly installed at the bottom ends of both buffer slides 24. A loading groove 7 is provided on the upper surface of the fixed pressure plate 6. Two elastic fixing straps 8 are fixedly connected to the upper surface of the fixed pressure plate 6, and both ends of the elastic fixing straps 8 are fixedly connected to the upper surface of the fixed pressure plate 6. A silicone anti-slip layer 19 is fixedly connected to the bottom surface of the fixed pressure plate 6. The fixed pressure plate 6 is located above the tray 4. Specifically, the support cover 2... 2 provides space for the spring 23 and the buffer slide 24, limiting their range of motion. The spring 23 can absorb vibration energy through elastic deformation of compression or stretching to achieve a shock absorption effect. The buffer slide 24 can slide along the inner wall of the support cover 22, working with the spring 23 to enhance the shock absorption effect and providing installation support for the universal self-locking wheel 25. The universal self-locking wheel 25 facilitates equipment movement and can self-lock after the equipment stops to prevent it from sliding. The loading slot 7 can be used to place small auxiliary tools or spare test blocks, expanding the equipment's storage function. The elastic fixing strap 8 can assist in fixing the items or test blocks in the loading slot 7 to prevent items from falling. The silicone anti-slip layer 19 can enhance the friction between the fixing plate 6 and the surface of the test block, improving the test block fixing effect, while avoiding damage caused by rigid contact between the fixing plate 6 and the test block.

[0018] Working principle: When the TOFD simulation test block is used in the non-destructive testing process using the turnover equipment, the user first pushes the equipment with the moving pusher 17 and moves the equipment to the TOFD simulation test block storage position using the universal self-locking wheel 25 at the bottom of the moving buffer 2. Then, the TOFD simulation test block is placed stably in the placement tray 4 on the positioning plate 3. At this time, according to the height of the test block, the rotating rod 92 in the drive component 9 is rotated. The rotating rod 92 drives the drive gear 93 to rotate under the support of the bearing ring 91. The drive gear 93 drives the meshing transmission gear 94 to rotate. The transmission gear 94 drives the threaded transmission rod 18 to rotate in the bearing seat 95. The threaded transmission rod 18 is threadedly connected to the threaded transmission plate 12 on the inner wall of the lifting slide 10, which enables the threaded transmission plate 12 to drive the lifting slide 10 to slide down along the inner wall of the support slide 5. Then, the lifting slide 10 drives the fixed pressure plate 6 to move down through the connecting block 11 until the silicone anti-slip layer 19 on the bottom surface of the fixed pressure plate 6 is tightly attached to the upper surface of the test block. After the test block is fixed, the operator pushes the moving pusher 17 to transfer the test block. When the equipment passes over uneven ground and generates vertical vibration, the spring 23 in the support cover 22 of the moving buffer 2 will be compressed or stretched by the buffer slide 24. The elastic deformation of the spring 23 absorbs the vibration energy and reduces the impact of vibration on the positioning plate 3 and the test block on the placement tray 4. After the equipment moves to the target position, the rotating rod 92 is rotated in the opposite direction. Through the above transmission structure, the fixed pressure plate 6 is raised, and the TOFD simulation test block can be taken out, completing one test block turnover process.

[0019] The above are merely preferred embodiments of the present utility model and do not limit the patent scope of the present utility model. All equivalent changes and modifications made within the scope of the present utility model shall still fall within the scope of the present utility model.
