Description

Technical Field

[0001] This utility model relates to the field of hydraulic metal structure inspection, specifically a non-destructive testing and positioning device for metal structures. Background Technology

[0002] The non-destructive testing device for hydraulic metal structures is a high-precision instrument specifically designed to assess the safety performance of hydraulic metal facilities (such as gates, pressure steel pipes, and hoists). It rapidly locates internal cracks, corrosion, weld defects, and other potential hazards using non-destructive techniques (such as ultrasonic waves, X-rays, magnetic particle testing, or eddy current testing). This device is typically waterproof, shockproof, and portable, allowing it to operate underwater, at heights, or in humid environments. Combined with intelligent analysis software, it provides real-time imaging of defect location and size, offering a scientific basis for preventative maintenance and life assessment of hydraulic engineering projects, significantly improving structural reliability and operational safety.

[0003] A specific example of a non-destructive testing (NDT) positioning device for metal structures can be found in application number CN201220104289.8. This device includes a fixed base, with a mounting frame at its bottom. A base is located on one side of the mounting frame. A first motor is mounted on the base away from the inner wall of the mounting frame. A screw is mounted on the first motor away from the base. A threaded block is fitted onto the screw. A connecting block is located at the bottom of the threaded block. Auxiliary supports are located on both sides of the connecting block. A first robotic arm is located at the end of the connecting block away from the threaded block. A first driving structure is located inside the first robotic arm. A second robotic arm is located at the bottom of the first robotic arm, with a second driving structure inside. A fixing structure is located at the bottom of the second robotic arm. The advantages of this positioning device are that it enables non-destructive contact transmission and positioning of metal structures, resulting in more accurate NDT data.

When using existing devices to fix irregularly shaped metal parts, the stability after fixing cannot be fully guaranteed. It can only fix conventional metal parts, resulting in poor applicability. Therefore, a non-destructive testing and positioning device for metal structures is proposed to address the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1-4As shown, a non-destructive testing and positioning device for metal structures includes an operating table 1; the top of the operating table 1 is fixedly connected to the bottom of the support frame 2 near the front position, the bottom of the support frame 2 is fixedly connected to the top of the detection head 3 near the rear position, and a positioning and fixing mechanism is provided at the top of the operating table 1.

[0024] The positioning and fixing mechanism includes a fixing block 10, which is set on the left and right sides above the operating table 1. Multiple sets of moving rods 11 are also sleeved inside the fixing block 10, and the moving rods 11 are slidably connected to the fixing block 10. The inner wall of the fixing block 10 is circular. One side of the moving rod 11 is fixedly connected to the side of the fixing plate 12. A return spring 13 is sleeved on the outside of the moving rod 11. One end of the return spring 13 is fixedly connected to the fixing block 10, and the other end of the return spring 13 is fixedly connected to the fixing plate 12.

[0025] During operation, the moving rod 11 will move outward along the inside of the fixed block 10, while the fixed plate 12 moves. When the fixed plate 12 moves, the return spring 13 on the outside of the moving rod 11 is stretched and extended.

[0026] Furthermore, the other side of the moving rod 11 is fixedly connected to one side of the fixed base 14, and a rotating block 15 is sleeved on the outer side of the other side of the fixed base 14. The fixed base 14 is rotatably connected to the rotating block 15, and the inner wall of the rotating block 15 is circular.

[0027] During operation, the chuck 16 rotates, causing the rotating block 15 to rotate along the inside of the fixed base 14.

[0028] Furthermore, the side end of the rotating block 15 is fixedly connected to the outer side of the chuck 16, the inner wall of the chuck 16 is fixedly connected to the outer side of the protective block 17, the protective block 17 is made of rubber, and the chuck 16 and the protective block 17 are also arc-shaped.

[0029] During operation, the two fixing blocks 10 move towards the center simultaneously, which will cause the chuck 16 to move simultaneously until the protective block 17 on the inner wall of the chuck 16 contacts the outer side of the irregular metal part. At the same time, the protruding part of the irregular metal part contacts the protective block 17 on the inner wall of the chuck 16. As the fixing blocks 10 continue to move inward, the protruding part of the irregular metal part will push the protective block 17 and the chuck 16 to rotate.

[0030] Furthermore, the fixing plate 12 is sleeved on the outside of the guide rod 18 near the upper position, and the guide rod 18 is slidably connected to the fixing plate 12. The bottom end of the guide rod 18 is fixedly connected to the top end of the fixing block 10, and the side end of the guide rod 18 is fixedly connected to the limiting block 19. The guide rod 18 is a circular rod design.

[0031] During operation, the fixed plate 12 moves, causing the return spring 13 on the outside of the moving rod 11 to be stretched and extended. At the same time, the fixed plate 12 moves along the outside of the guide rod 18, and the limiting block 19 is used to limit the position of the fixed plate 12 to prevent the fixed plate 12 from disengaging from the outside of 28.

[0032] Furthermore, the left end of the operating table 1 is fixedly connected to the motor 20, the right end of the motor 20 passes through the side end of the operating table 1 to reach the inside of the operating table 1, and the right end of the motor 20 is fixedly connected to the left end of the bidirectional threaded rod 21. The right end of the bidirectional threaded rod 21 is inserted into the operating table 1, and the bidirectional threaded rod 21 is rotatably connected to the operating table 1. The left and right ends of the outer side of the bidirectional threaded rod 21 are also fitted with moving blocks 22, and the bidirectional threaded rod 21 is threadedly connected to the moving blocks 22. The top end of the moving blocks 22 is fixedly connected to the bottom end of the fixed block 10.

[0033] During operation, the irregularly shaped metal parts are placed on the top of the operating table 1 near the center. The motor 20 on the left side of the operating table 1 is then started. When the motor 20 starts, it drives the bidirectional threaded rod 21 to rotate. When the bidirectional threaded rod 21 rotates, it drives the moving blocks 22 on both sides to move towards the center at the same time. Simultaneously, the movement of the moving blocks 22 drives the fixed block 10 to move.

[0034] Furthermore, the inside of the operating table 1 is fixedly connected to the outside of the guide plate 23 near the upper position. The guide plate 23 is sleeved on the moving block 22 near the upper position, and the guide plate 23 is slidably connected to the moving block 22. The inner wall of the guide plate 23 is square.

[0035] When the moving block 22 moves during operation, the part of the moving block 22 that is close to the upper position will move along the inside of the guide plate 23.

[0036] Working principle: When it is necessary to perform positioning and inspection on irregularly shaped metal parts, first place the irregularly shaped metal parts on the top of the operating table 1 near the center. Then start the motor 20 on the left side of the operating table 1. When the motor 20 starts, it drives the bidirectional threaded rod 21 to rotate. When the bidirectional threaded rod 21 rotates, it drives the moving blocks 22 on both sides to move towards the center at the same time. When the moving blocks 22 move, they will also move along the inside of the guide plate 23 near the top position. At the same time, the movement of the moving blocks 22 drives the fixed blocks 10 to move. When the fixed blocks 10 on both sides move towards the center at the same time, they will drive the chuck 16 to move at the same time until the protective block 17 on the inner wall of the chuck 16 contacts the outer side of the irregularly shaped metal parts. At the same time, the irregularly shaped metal parts are relatively convex. When the protective block 17 on the inner wall of the chuck 16 contacts the fixed block 10 and continues to move inward, the protruding part of the irregular metal part will push the protective block 17 and the chuck 16 to rotate. When the chuck 16 rotates, it will drive the rotating block 15 to rotate along the inside of the fixed seat 14. At the same time, the moving rod 11 will move outward along the inside of the fixed block 10. Meanwhile, the fixed plate 12 will move. When the fixed plate 12 moves, the return spring 13 on the outside of the moving rod 11 will be stretched and extended. At the same time, the fixed plate 12 will move along the outside of the guide rod 18. The limiting block 19 is used to limit the position of the fixed plate 12 to prevent the fixed plate 12 from disengaging from the outside of the guide rod 18 until the protective block 17 on the inner wall of the chuck 16 clamps the outside of the irregular metal part.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
