Description

Technical Field

[0001] This utility model relates to the field of flaw detection technology, specifically to a dynamic water immersion ultrasonic flaw detection device. Background Technology

[0002] Die casting is a precision casting method that uses high pressure to force molten metal into a complex-shaped metal mold. Die castings are parts formed by pressure casting. Some die castings have defects, and ultrasonic testing equipment is needed to inspect the castings. Ultrasonic testing generally uses ultrasonic waves for inspection.

[0003] Common dynamic water immersion ultrasonic flaw detection equipment also has some problems, such as: during the test, the staff needs to reach into the water tank to pick up or place the die-cast parts, which is inconvenient to raise and lower the placement plate inside the water tank, resulting in poor flexibility.

[0004] Therefore, we propose a novel dynamic water immersion ultrasonic flaw detection device to improve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a dynamic water immersion ultrasonic flaw detection device to solve the problem mentioned in the background art that it is inconvenient to raise and lower the placement plate inside the water tank and that the flexibility is poor.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dynamic water immersion ultrasonic flaw detection device, including a base, a water tank at the top of the base, a transparent glass at the front end of the water tank, fixed rods fixedly connected to both sides of the top of the base, a support plate fixedly connected to the top of the fixed rods, an electric slide rail at the top of the support plate, a connecting block at the top of the electric slide rail, casters installed at the four corners of the bottom of the base, and a lifting structure for easy loading and unloading of materials inside the water tank;

[0007] The lifting structure includes a support rod, a movable frame, and a connecting rod. A drive motor is installed at the bottom of the rear end of the transparent glass. A connecting shaft is fixedly connected to the output end of the drive motor. A connecting rod is fixedly connected to the front end of the connecting shaft. A rotating block is installed at the top of the front end of the connecting rod. Limiting rods are fixedly connected to both sides of the bottom inside the transparent glass. A movable frame is provided outside the rotating block. A support rod is fixedly connected to the top of the movable frame. A placement plate is fixedly connected to the top of the support rod.

[0008] Preferably, a hydraulic cylinder is installed at the front end of the connecting block, an ultrasonic probe is installed at the bottom end of the hydraulic cylinder, and a connecting wire is installed on one side of the ultrasonic probe.

[0009] Preferably, the placement plate has reserved slots on both sides inside, and the placement plate slides up and down outside the limiting rod through the reserved slots.

[0010] Preferably, a connecting frame is installed at the top left side of the ultrasonic probe, and limit blocks are fixedly connected to the right side of the front end of the electric slide rail and the top right side of the connecting frame, respectively. A protective tube is provided on the right side of the front end of the electric slide rail, and a flexible tube is fixedly connected between the protective tubes. A fixing block is provided at one end inside the protective tube.

[0011] Preferably, the flexible tube and the protective tube are disposed inside the connecting wire, and multiple sets of the flexible tube and the protective tube are respectively disposed, and the limiting block is disposed outside the protective tube.

[0012] Preferably, a protective shell is installed at the front end of the right side of the water tank, a servo motor is installed at the top of the protective shell, a threaded rod is fixedly connected to the output end of the servo motor, a threaded sleeve is provided at the bottom end of the threaded rod, an installation plate is installed at the front end of the threaded sleeve, a cleaning brush is installed at the bottom end of the installation plate, and a limit groove is formed at the front end of the protective shell.

[0013] Preferably, the rear end of the right side of the mounting plate slides up and down inside the limiting groove, and the front end of the mounting plate and the cleaning brush is set with transparent glass.

[0014] Preferably, the threaded rod is movably connected inside the protective shell, and the threaded sleeve and the threaded rod cooperate with each other.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the dynamic water immersion ultrasonic flaw detection equipment not only makes it easy to raise and lower the placement plate and prevents the connecting wires from being immersed in the water tank, but also makes it easy to clean the transparent glass;

[0016] By setting up limit rods, support rods, movable frames, connecting rods, rotating blocks, drive motors, and connecting shafts, the drive motor is activated when the die-casting part at the top of the placement plate needs to be retrieved. The drive motor drives the rotating block to rotate inside the movable frame through the connecting shaft and connecting rods, which in turn allows the movable frame to lift the placement plate through the support rods. The lifting of the placement plate allows the die-casting part to rise out of the water surface, and workers can directly retrieve the die-casting part from the top of the placement plate without having to put their hands into the water tank.

[0017] The system includes a flexible tube, a limiting block, a connecting frame, a protective tube, and a fixing block. The fixing block can fix the connecting wire inside the protective tube and the flexible tube. Inside the flexible tube, the connecting wire is bent. When the electric slide rail and the hydraulic cylinder move the ultrasonic probe, the bent connecting wire will move with the flexible tube. The flexible tube and the protective tube can support and limit the connecting wire, preventing excess connecting wire from being soaked in the water tank and affecting the service life of the connecting wire.

[0018] Equipped with a servo motor, threaded rod, limit slide, mounting plate, threaded sleeve, and cleaning brush, the servo motor is activated when there is dust and impurities on the surface of the transparent glass. The servo motor drives the threaded rod to rotate, and the rotation of the threaded rod causes the threaded sleeve to move the mounting plate up and down at the front end of the transparent glass. This allows the cleaning brush at the bottom of the mounting plate to clean the dust and impurities on the surface of the transparent glass, preventing excessive dust and impurities at the front end of the transparent glass from affecting the user's observation of the inside of the water tank.

[0024] 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 protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1-4The ultrasonic flaw detection equipment includes a base 1, a water tank 2 at the top of the base 1, a transparent glass 5 at the front end of the water tank 2, fixed rods 4 on both sides of the top of the base 1, a support plate 9 at the top of the fixed rods 4, an electric slide rail 10 at the top of the support plate 9, a connecting block 12 at the top inside the electric slide rail 10, casters 3 at the four corners of the bottom of the base 1, and a lifting structure for easy loading and unloading of materials inside the water tank 2.

[0026] The lifting structure includes a support rod 20, a movable frame 21, and a connecting rod 22. A drive motor 28 is installed at the bottom of the rear end of the transparent glass 5. A connecting shaft 29 is fixedly connected to the output end of the drive motor 28. A connecting rod 22 is fixedly connected to the front end of the connecting shaft 29. A rotating block 27 is installed at the top of the front end of the connecting rod 22. Limiting rods 6 are fixedly connected to both sides of the bottom end inside the transparent glass 5. A movable frame 21 is provided outside the rotating block 27. A support rod 20 is fixedly connected to the top of the movable frame 21. A placement plate 7 is fixedly connected to the top of the support rod 20.

[0027] A hydraulic cylinder 11 is installed at the front end of the connecting block 12, an ultrasonic probe 8 is installed at the bottom end of the hydraulic cylinder 11, a connecting wire 14 is installed on one side of the ultrasonic probe 8, and reserved slots are opened on both sides inside the placement plate 7. The placement plate 7 slides up and down outside the limiting rod 6 through the reserved slots.

[0028] Specifically, if Figure 1 and Figure 3 As shown, when it is necessary to retrieve the die-cast part from the top of the placement plate 7, the drive motor 28 is activated. The drive motor 28 drives the rotating block 27 to rotate inside the movable frame 21 through the connecting shaft 29 and the connecting rod 22. This allows the movable frame 21 to lift the placement plate 7 through the support rod 20. The lifting of the placement plate 7 allows the die-cast part to rise out of the water surface. The operator can directly retrieve the die-cast part from the top of the placement plate 7 without having to put their hands inside the water tank 2 to contact the water.

[0029] Example 2: A connecting bracket 17 is installed at the top left side of the ultrasonic probe 8. Limiting blocks 15 are fixedly connected to the right side of the front end of the electric slide rail 10 and the top right side of the connecting bracket 17, respectively. A protective tube 30 is provided on the right side of the front end of the electric slide rail 10. A flexible tube 13 is fixedly connected between the protective tubes 30. A fixing block 31 is provided at one end inside the protective tube 30. The flexible tube 13 and the protective tube 30 are located inside the connecting wire 14. Multiple sets of flexible tubes 13 and protective tubes 30 are provided. The limiting block 15 is located outside the protective tube 30.

[0030] Specifically, if Figure 1 and Figure 4As shown, the fixing block 31 can fix the connecting wire 14 inside the protective tube 30 and the hose 13. Inside the hose 13, the connecting wire 14 is bent. When the electric slide rail 10 and the hydraulic cylinder 11 drive the ultrasonic probe 8 to move, the bent connecting wire 14 will move with the hose 13. The hose 13 and the protective tube 30 can support and limit the connecting wire 14, preventing excess connecting wire 14 from being soaked inside the water tank 2 and affecting the service life of the connecting wire 14.

[0031] Example 3: A protective shell 24 is installed at the front end of the right side of the water tank 2. A servo motor 16 is installed at the top of the protective shell 24. A threaded rod 18 is fixedly connected to the output end of the servo motor 16. A threaded sleeve 25 is provided at the bottom end of the threaded rod 18. An installation plate 23 is installed at the front end of the threaded sleeve 25. A cleaning brush 26 is installed at the bottom end of the installation plate 23. A limiting groove 19 is opened at the front end of the protective shell 24. The rear end of the right side of the installation plate 23 slides up and down inside the limiting groove 19. The front end of the installation plate 23 and the cleaning brush 26 are provided with transparent glass 5. The threaded rod 18 is movably connected inside the protective shell 24. The threaded sleeve 25 and the threaded rod 18 cooperate with each other.

[0032] Specifically, if Figure 1 and Figure 2 As shown, when there is dust and impurities on the surface of the transparent glass 5, the servo motor 16 is activated. The servo motor 16 drives the threaded rod 18 to rotate. The rotation of the threaded rod 18 can cause the threaded sleeve 25 to move the mounting plate 23 up and down at the front end of the transparent glass 5. This allows the cleaning brush 26 at the bottom of the mounting plate 23 to clean the dust and impurities on the surface of the transparent glass 5, preventing excessive dust and impurities at the front end of the transparent glass 5 from affecting the user's observation of the inside of the water tank 2.

[0033] Working Principle: When in use, the drive motor 28 is activated. The drive motor 28, via the connecting shaft 29 and connecting rod 22, drives the rotating block 27 to rotate inside the movable frame 21. This causes the movable frame 21 to lift the placement plate 7 via the support rod 20. After the placement plate 7 reaches the appropriate position, the die-cast part is placed on top of the placement plate 7. After placement, the drive motor 28 is activated again, and it again drives the rotating block 27 to rotate via the connecting shaft 29 and connecting rod 22, causing the movable frame 21 to lower the placement plate 7 to the bottom of the water tank 2. Then, the electric slide rail 10 and hydraulic cylinder 11 are activated to lower the ultrasonic probe 8 to inspect the die-cast part. The inspection results are transmitted to the display screen for easy viewing by staff. After inspection, the placement plate 7 is raised again, allowing the die-cast part to rise above the water surface. Staff can then directly retrieve the die-cast part from the top of the placement plate 7 without putting their hands into the water. The interior of the tank 2 is in contact with water. The fixing block 31 can fix the connecting wire 14 inside the protective tube 30 and the hose 13. Inside the hose 13, the connecting wire 14 is bent. When the electric slide rail 10 and the hydraulic cylinder 11 move the ultrasonic probe 8, the bent connecting wire 14 will move with the hose 13. The hose 13 and the protective tube 30 can support and limit the connecting wire 14, preventing excess connecting wire 14 from being soaked inside the tank 2 and affecting the service life of the connecting wire 14. When there is dust and impurities on the surface of the transparent glass 5, the servo motor 16 is activated. The servo motor 16 drives the threaded rod 18 to rotate. The rotation of the threaded rod 18 can cause the threaded sleeve 25 to move the mounting plate 23 up and down at the front end of the transparent glass 5, so that the cleaning brush 26 at the bottom of the mounting plate 23 can clean the dust and impurities on the surface of the transparent glass 5, preventing too much dust and impurities at the front end of the transparent glass 5 from affecting the user's observation of the inside of the tank 2.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
