Description

Technical Field

[0001] This utility model relates to the field of oil storage tank testing technology, and in particular to a rotary device for non-destructive testing of tank bodies. Background Technology

[0002] Currently, before an oil storage tank is officially put into use, a comprehensive non-destructive testing process must be conducted in accordance with relevant standards and specifications. Inspectors typically use specialized non-destructive testing instruments and equipment to meticulously examine key components of the tank, focusing on critical parameters such as the integrity of the tank's welds and the uniformity of the steel plate wall thickness. However, due to the typically large size and weight of oil storage tanks, manually rotating them during actual testing is extremely difficult and carries a high risk of safety accidents.

[0003] To address the aforementioned issues, existing technology has designed a rotary non-destructive testing device for oil storage tanks. This device supports the storage tank with dual shafts and then rotates the tank via a lead screw and drive rollers. However, during use, the lack of a limit switch for the oil storage tank causes it to sway or shift during rotation, leading to decreased testing accuracy and potentially serious safety issues such as tank slippage. On the other hand, existing rotary non-destructive testing devices are insufficient to meet the testing requirements of oil storage tanks of various sizes if a limit switch is desired.

[0004] Therefore, there is an urgent need to propose a rotary device for non-destructive testing of tanks to solve the above problems. Utility Model Content

One end of the rotating roller is connected to the output end of the drive motor, and the other end is rotatably connected to the other support block. The two rotating rollers can support the tank body under the drive of the lifting platform. The first direction and the second direction are located in the same plane, and the first direction is perpendicular to the second direction.

[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1-4As shown, this utility model provides a rotating device for non-destructive testing of tanks, including a support assembly 1, a drive assembly 2, a lifting mechanism 3, and two rotating assemblies 4. The support assembly 1 includes a base 11 and two limiting members 12. The two limiting members 12 are spaced apart on the base 11 along a first direction and enclose the base 11 to form an installation space. The tank 100 is located in the installation space and is rotatably connected to one of the limiting members 12. The drive assembly 2 is disposed on the other limiting member 12 and is used to drive the tank 100 to rotate along its own axis. The lifting mechanism 3 includes a lifting platform 31 and a lifting assembly 32. Component 32 is mounted on base 11 and can drive lifting platform 31 to move vertically; rotating components 4 are arranged parallel to and spaced apart along a second direction. Each rotating component 4 includes a first drive motor 41, a rotating roller 42, and two support blocks 43. The two support blocks 43 are spaced apart on lifting platform 31 along the first direction. The first drive motor 41 is fixedly mounted on one of the support blocks 43. One end of the rotating roller 42 is connected to the output end of the drive motor 41, and the other end is rotatably connected to the other support block 43. The two rotating rollers 42 can support tank 100 under the drive of lifting platform 31. The first direction and the second direction are located in the same plane, and the first direction is perpendicular to the second direction.

[0039] A stable installation space is formed by the base 11 and two limiting members 12. One of the limiting members 12 is rotatably connected to the tank 100 to achieve axial positioning, which effectively prevents the tank 100 from shaking or shifting during rotation and ensures stability during rotation. Furthermore, when detecting tanks 100 of different sizes, the lifting assembly 32 can drive the lifting platform 31 to drive multiple parallel rotating rollers 42 to closely fit the bottom of the tank 100 to accommodate tanks 100 of different diameters and increase the versatility of the rotating device. At the same time, when the drive assembly 2 directly drives the tank 100 to rotate, the first drive motor 41 drives the rotating rollers 42 to rotate, which can assist the tank 100 in rotating and enhance the stability of the tank 100 rotation.

[0040] In this embodiment, the base 11 is a cube and the limiting member 12 is a rectangular plate.

[0041] In other embodiments, the base 11 may also be a column and the limiting member 12 may also be a trapezoidal plate. The shape and structure of the base 11 and the limiting member 12 are not specifically limited here.

[0042] Specifically, such as Figure 1 and 2As shown, the rotary device for non-destructive testing of tanks also includes a fixing component 5, which is fixedly installed at one end of the tank 100 and rotatably connected to one of the limiting components 12. The fixing component 5 makes the installation and disassembly of the tank 100 more convenient and faster. When different tanks 100 need to be tested, the fixing component 5 can be connected or separated from the tank 100 or the limiting component 12 through simple operations, without the need for complicated adjustment and positioning processes.

[0043] In this embodiment, two fixing members 5 are provided, which are fixedly installed at opposite ends of the tank body 100. One fixing member 5 is rotatably connected to one of the limiting members 12, and the other is fixedly connected to the driven wheel 23. When installing the tank body 100, the fixing members 5 at both ends provide a clear positioning reference for the tank body 100. The fixing member 5 at one end is rotatably connected to the limiting member 12 to ensure that the lateral position of the tank body 100 in the installation space is accurate and can rotate freely; the fixing member 5 at the other end is fixedly connected to the driven wheel 23 to ensure the synchronous movement of the driven wheel 23 and the tank body 100.

[0044] Specifically, such as Figure 2 As shown, the drive assembly 2 includes a second drive motor 21, a driving wheel 22, and a driven wheel 23. The drive motor 21 is fixedly mounted on the limiting member 12. The driving wheel 22 is connected to the output end of the motor 21. The driven wheel 23 is fixedly mounted on the tank body 100 and is driven by the driving wheel 22. The second drive motor 21 provides stable power output. The transmission connection between the driving wheel 22 and the driven wheel 23 ensures that power can be reliably transmitted to the tank body 100, enabling the tank body 100 to rotate at a set speed and direction. This ensures the stability of the tank body 100's rotation during non-destructive testing, thereby improving the accuracy and reliability of the test results.

[0045] Optionally, the drive assembly 2 also includes a transmission belt 24, which is wound around the drive pulley 22 and the driven pulley 23. When the second drive motor 21 drives the drive pulley 22 to rotate and drives the driven pulley 23 and the tank 100 to rotate, the transmission belt 24 can provide a certain degree of buffering and shock absorption. When the second drive motor 21 starts or stops, the elasticity of the transmission belt 24 can absorb this energy, reducing the impact of vibration and shock on the tank 100 and the entire rotating device. Furthermore, the installation of the transmission belt 24 is relatively simple, requiring no complex alignment adjustments. When the transmission belt 24 is worn or damaged, replacement is also convenient; simply remove the old transmission belt 24 and install the new one. This simple installation and maintenance method reduces maintenance costs and time, and improves efficiency.

[0046] Optionally, the driving wheel 22 and the driven wheel 23 are meshed together. The meshing connection between the driving wheel 22 and the driven wheel 23 can achieve a precise transmission ratio, and the rotation angle and speed of the tank 100 can be precisely controlled. Moreover, the meshing relationship is stable, which can better maintain stability during the rotation of the tank 100, reduce the shaking of the tank 100 caused by transmission instability, and further improve the stability of the rotation of the tank 100 and the reliability of detection.

[0047] Specifically, the base 11 is provided with a receiving groove, the lifting assembly 32 is disposed in the receiving groove, and the lifting platform 31 is covered by the opening of the receiving groove. Placing the lifting assembly 32 in the receiving groove of the base 11 makes the structure of the entire rotary device more compact and effectively utilizes the internal space of the base 11. The lifting platform 31 covering the opening of the receiving groove not only protects the lifting assembly 32 inside the receiving groove 11, but also makes the overall structure of the rotary device more regular.

[0048] Specifically, such as Figure 3 As shown, the lifting mechanism 3 also includes a base plate 33, which has a first strip groove 330. The bottom of the lifting platform 31 has a second strip groove. The lifting assembly 32 includes a lifting motor 321, a bidirectional lead screw 322, two lifting rods 323, two sliding blocks 324, and two moving blocks 325. The lifting motor 321 is fixedly installed on the base 11. The bidirectional lead screw 322 is connected to the output end of the lifting motor 321 and extends into the first strip groove 330 along its length. The two sliding blocks 324 are slidably disposed in the first strip groove 330 and are screwed one-to-one with the forward thread and reverse thread of the bidirectional lead screw 322. The two moving blocks 325 are slidably disposed in the second strip groove. The two lifting rods 323 are rotatably connected, with one end of each lifting rod 323 rotatably connected to the two sliding blocks 324 and the other end rotatably connected to the two moving blocks 325.

[0049] When the lifting motor 321 starts, it drives the bidirectional lead screw 322 to rotate. Since the two sliding blocks 324 are screwed one-to-one into the forward and reverse threaded parts of the bidirectional lead screw 322, the two sliding blocks 324 can move synchronously towards or away from each other, driving the two moving blocks 325 to move towards or away from each other. This changes the angle between the two cross-rotating lifting rods 323, thereby causing the lifting platform 31 to rise and fall vertically. By controlling the number of rotations and direction of the lifting motor 321, the movement distance of the sliding blocks 324 within the first slot 330 can be precisely controlled, thereby accurately adjusting the lifting height of the lifting platform 31.

[0050] In other embodiments, the lifting platform 31 can also be driven to move vertically by a hydraulic cylinder or a pneumatic cylinder.

[0051] More specifically, the base plate 33 is provided with two first strip-shaped grooves 330 spaced apart, and two sets of lifting components 32 are provided, with the two sets of lifting components 32 correspondingly arranged within the two first strip-shaped grooves 330. The two sets of lifting components 32 work together to make the lifting platform 31 and the rotating roller 42 more stable when supporting the tank 100, thereby improving the stability of the entire rotating device. Furthermore, the two sets of lifting components 32 can share a greater weight, improving the rotating device's load-bearing capacity for large and heavy tanks 100.

[0052] In other embodiments, three sets of lifting components 32 may be provided, and the number of lifting components 32 is not specifically limited here.

[0053] Specifically, such as Figure 4 As shown, the rotating assembly 4 includes an anti-slip element 44, which is sleeved on the outer surface of the rotating roller 42. The anti-slip element 44 increases the friction between the rotating roller 42 and the tank 100, enabling the rotating roller 42 to more effectively transmit its rotational power to the tank 100, thereby better assisting the tank 100 in rotating.

[0054] More specifically, multiple anti-slip components 44 are provided, and these multiple anti-slip components 44 are spaced apart along the length of the rotating roller 42. When the tank 100 rotates, the anti-slip components 44 at different positions work simultaneously to avoid slippage caused by insufficient local friction.

[0055] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
