Description

Technical Field

[0001] This utility model relates to the field of pressure vessel manufacturing technology, specifically to a pressure vessel verticality inspection fixture. Background Technology

[0002] Pressure vessels are closed devices that hold gas or liquid and bear a certain pressure. In order to more effectively implement scientific management and safety supervision, pressure vessels are divided into three categories according to working pressure, the hazard of the medium and their role in production.

[0003] In the production process of pressure vessels, it is often necessary to check the verticality of the pressure vessel. Traditionally, the inspection is carried out manually, by checking the vertical line or by observation. The efficiency and accuracy of manual inspection are relatively low. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a pressure vessel verticality inspection fixture for mechanical testing, addressing the shortcomings mentioned in the background art.

[0006] A support L-plate is connected to the top of one side of the support base, and a laser sensor that matches the limiting groove is connected to the bottom of the top of the support L-plate.

[0007] The top of the support base is provided with a container positioning ring, and the top of the support base is provided with multiple annularly arranged limiting holes. The bottom of the container positioning ring is connected with a limiting rod that matches the limiting holes.

[0008] Furthermore, the support base has a groove in the middle, a drive motor is connected to the bottom of the groove, a rotating disk is connected to the top power end of the drive motor, a gear ring is provided on the outer side of the top of the rotating disk, and the drive screw extends into the groove and is connected to a gear that meshes with the gear ring. The gear ring facilitates the synchronous driving of the rotation of multiple drive screws.

[0009] Furthermore, the inner side of the groove is provided with a limiting ring groove that matches the rotating disk, and the outer side of the rotating disk is connected with a limiting ring block that extends into the limiting ring groove, so as to ensure the stable rotation of the rotating disk.

[0010] Furthermore, the inner side of the container positioning ring is provided with a groove that matches the limiting slide and the laser emitter, which facilitates the laser emitter to perform penetration operations.

[0011] Furthermore, a support base plate is connected to the bottom of the support base, and an anti-slip pad is connected to the bottom of the support base plate to facilitate the overall operation of the support equipment.

[0012] The advantages of this pressure vessel verticality inspection fixture compared to existing technologies are as follows: This fixture, through a bottom-driven synchronous drive screw and laser emitter, combined with a top-mounted laser sensor, can perform precise and rapid verticality inspection on cylindrical pressure vessels.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] Combined with appendix Figure 1-3A pressure vessel verticality inspection fixture includes a support base 1, a support base plate 19 connected to the bottom of the support base 1, and an anti-slip pad 20 connected to the bottom of the support base plate 19. The support base plate 19 and the anti-slip pad 20 work together to ensure stable support of the equipment. The top of the support base 1 has multiple evenly arranged annular limiting grooves 3. A drive screw 4 is rotatably connected within each limiting groove 3. A limiting slider 10, threadedly connected to the drive screw 4, is slidably connected within each limiting groove 3. A laser emitter 11 is connected to the top of the limiting slider 10. A support L-plate 2 is connected to the top of one side of the support base 1. The top of the support L-plate 2... The pressure vessel is connected to a laser sensor 17 with a matching limiting slide groove 3. Through the limiting slider 10 and the laser emitter 11, which can move synchronously inward or outward, the laser sensor can be synchronously irradiated upward. In actual operation, the cylindrical pressure vessel is placed in the center position, and then the laser generator 11 generates a laser. The top laser sensor 17 then senses it synchronously. When the pressure vessel is tilted or has a large vertical deviation, one side of the laser generator 11 will often be blocked, while the other laser generators 11 will not be blocked. Such a pressure vessel needs to be scrapped or rebuilt. If multiple laser generators 11 are blocked synchronously or almost synchronously, it means that the verticality of the cylindrical pressure vessel is qualified.

[0019] Combined with appendix Figure 1-2 The support base 1 has a container positioning ring 14 inserted into its top. The top of the support base 1 has multiple annularly arranged limiting holes 15. The bottom of the container positioning ring 14 is connected to a limiting rod 16 that mates with the limiting holes 15. The inner side of the container positioning ring 14 has a slot 18 that mates with the limiting groove 3 and the laser emitter 11. This is because manual alignment is inconvenient when placing the container, hence the container positioning ring 14. The container positioning ring 14 is generally set in different sizes. As shown in the figure, the positions of the limiting holes 15 are also set according to the size of the container. The limiting rod 16 is inserted into the limiting hole 15 to fix the container positioning ring 14, thus facilitating direct placement into the pressure vessel. The slot 18 is designed so that if the container positioning ring 14 were used, the laser movement would be blocked by it. Therefore, the slot 18 ensures that the laser is not blocked by the container positioning ring 14 during detection.

[0020] The support base 1 has a groove 5 in the middle. A drive motor 6 is connected to the bottom of the groove 5. A rotating disk 7 is connected to the top power end of the drive motor 6. A toothed ring 8 is provided on the outer side of the top of the rotating disk 7. The drive screw 4 extends into the groove 5 and is connected to a gear 9 that meshes with the toothed ring 8. That is, by starting the drive motor 6, the rotating disk 7 is driven to rotate. Through the toothed ring 8 and the gear 9, multiple drive screws 4 can be driven to rotate synchronously, thereby driving the synchronous movement of the limiting slider 10 and the laser emitter 11. The inner side of the groove 5 is provided with a limiting ring groove 12 that matches the rotating disk 7. A limiting ring block 13 extending into the limiting ring groove 12 is connected to the outer side of the rotating disk 7.

[0021] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
