Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically a non-destructive testing device for pressure vessels. Background Technology

[0002] As is well known, pressure vessels are widely used in production and daily life sectors such as machinery, petroleum, and chemical industries, and are among the high-risk pressure-bearing special equipment. Explosions or leaks in these vessels typically cause destructive accidents, making non-destructive testing of pressure vessels during manufacturing and after use particularly important.

[0003] Chinese Utility Model Announcement No. CN212658686U discloses a non-destructive testing device for pressure vessels, including a base plate, a U-shaped frame, and a collar. The base plate has U-shaped frames symmetrically installed at both ends, and a guide rod is horizontally fixed between the two U-shaped frames. Sliding sleeves are installed on both sides of the collar and are slidably fitted onto the guide rod. A toothed ring is rotatably embedded on the inner side of the collar, and a detection probe is installed on the toothed ring. A second motor is installed on the outer wall of the collar, and a gear that meshes with the toothed ring is installed at the output end of the second motor. A translation mechanism that drives the collar to slide horizontally is also installed between the two side supports. The base plate is provided with a support frame for supporting the pressure vessel.

[0004] While the device improves the accuracy of the test results, installing the pressure vessel requires workers to carry it through the guide rod and U-shaped frame, and then through the collar to install it on the support frame. This is not very convenient, and the efficiency could be improved. Furthermore, the spacing between the support frames is fixed, meaning only pressure vessels of the same model can be installed for testing. Therefore, its practicality is not very good, and there is room for improvement. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a non-destructive testing device for pressure vessels, which has the following beneficial effects:

[0017] This non-destructive testing device for pressure vessels allows for the movement of two support plates to the right side of the base via the rotation of a second motor when a pressure vessel needs to be installed. This enables one of the support plates to move to the right side of the fixed frame on the right side. When the pressure vessel is installed on the placement plate, it is not affected by the connecting rod and the moving ring, thus improving installation efficiency. Furthermore, the distance between the two placement plates can be adjusted by moving the moving block within the slot of the support plate, allowing for the installation and testing of different types of pressure vessels, thereby enhancing its practicality.

[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 protection scope of the present utility model.

[0023] Please see Figure 1-3 This utility model discloses a non-destructive testing device for pressure vessels, comprising a base plate 1 and a fixed frame 2. A first lead screw 3 is rotatably connected to the upper part of the fixed frame 2, and a first motor 4 is installed at one end of the first lead screw 3. When the first motor 4 is started, it rotates, driving the first lead screw 3 to rotate. A movable ring 5 is threadedly connected to the first lead screw 3, and an inner ring is rotatably connected to the movable ring 5. A detection device 6 is provided on the inner wall of the inner ring. When the first lead screw 3 rotates, it drives the threaded movable ring 5 and the detection device 6 to move, thereby inspecting the pressure vessel. A toothed ring is provided on the outside of the inner ring, and a gear 18 is meshed with it. A third motor 19 is installed at one end of the gear 18 and is fixed together with the movable ring 5. The third motor 19 is started, and its rotation drives the gear 18 to rotate, which in turn drives the inner ring and the detection device 6 to rotate around the pressure vessel for detection. A sliding groove 7 is provided in the middle of the base, and a movable bracket is slidably connected thereto. A second lead screw 8 is threadedly connected to the lower part of the movable bracket, and a second motor 9 is installed at one end of the second lead screw 8. The second motor 9 is started, and its rotation drives the second lead screw 8 to rotate. The movable bracket moves within the sliding groove 7 of the base. A slot 10 is provided on the upper part of the movable bracket, and a movable plate for placing the pressure vessel is engaged. Moving the movable bracket to the right side near the base makes it easier to place the pressure vessel on the movable plate, saving the staff some physical effort.

[0024] The movable support includes a sliding block 11 that slides within a groove 7 in the base. A support plate 12 with a slot 10 is provided on the upper part of the sliding block 11. The sliding block 11 slides within the groove 7 in the base, causing the support plate 12 to move on the base.

[0025] The upper part of the support plate 12 is provided with a threaded hole, which is through the slot 10. The threaded hole is connected to a fastening bolt 13. The pressure vessel is placed on the moving plate, and then the fastening bolt 13 is tightened to fix the moving plate on the support plate 12, so that the moving plate no longer moves.

[0026] The movable plate includes a movable block 14 that is snapped into the slot 10. A placement plate 15 is provided on the upper part of the movable block 14. An installation groove 16 for placing pressure vessels is provided in the middle of the placement plate 15. The movable block 14 moves in the slot 10. By adjusting the distance between the two placement plates 15, pressure vessels of different models can be placed. Then, both ends of the pressure vessel are placed into the installation groove 16 of the placement plate 15.

[0027] The cross-section of the moving block 14 is T-shaped, and the cross-section of the slot 10 is also T-shaped, which ensures that the moving block 14 moves left and right along the slot 10, but does not move in other directions.

[0028] Connecting rods 17 are connected through both sides of the moving ring 5. The two ends of the connecting rods 17 are fixed together with the fixed frame 2. The connecting rods 17 restrict the moving ring 5 and ensure that the moving ring 5 moves along the axis of the first lead screw 3.

[0029] In summary, when using this pressure vessel non-destructive testing device, if the operator needs to test the pressure vessel, the second motor 9 is started. The second motor 9 rotates, driving the second lead screw to rotate, thereby moving the support plate 12 to the right side of the base. When the support plate 12 on the left side moves close to the fixed frame 2 on the right side, the second motor 9 is turned off, the fastening bolts 13 on the support plate 12 are loosened, and the two placement plates 15 are pushed to move. The distance between the two placement plates 15 is adjusted so that the distance is level with the pressure vessel. The pressure vessel is then placed in the mounting groove 16 of the placement plate 15, the fastening bolts 13 are tightened, the moving block 14 is fixed, and the placement plate 15 is fixed. Then the second motor 9 is started again, and the second motor 9 reverses, driving the second lead screw 8 to reverse, thereby moving the support plate 12 back to its original position, facilitating the testing device 6 to test the pressure vessel.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
