Description

Technical Field

[0001] This utility model relates to the field of auxiliary technology for tank inspection, and in particular to an auxiliary device for scanning and inspecting atmospheric pressure tanks. Background Technology

[0002] Atmospheric pressure storage tanks are widely used in petroleum, chemical and other fields. The integrity of the tank body is directly related to production safety. Therefore, they need to be inspected regularly with the help of scanning equipment. Auxiliary devices are key components to ensure efficient inspection.

[0003] Existing scanning auxiliary devices have significant shortcomings. On the one hand, their clamping mechanisms are mostly rigid designs, lacking effective buffering and limiting structures. They cannot release force during clamping, making them prone to crushing damage to the tank surface due to improper clamping force control, especially for thin-walled or easily deformable storage tanks, where the risk of damage is even higher. On the other hand, the existing devices have poor coordination between the rotation, clamping, and lifting mechanisms, making it difficult to drive the scanning equipment to achieve uniform and detailed all-around scanning. Furthermore, the lifting structure often lacks stable buffer components, making the scanning equipment prone to shaking during loading and bumping during unloading. This not only affects detection accuracy but also poses a safety hazard of equipment falling. Overall detection efficiency and safety urgently need improvement. Utility Model Content

[0026] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0027] Reference Figure 1-4This utility model provides an auxiliary device for inspecting and scanning atmospheric pressure storage tanks, which includes a fixed base plate 1 and a servo motor 6 fixedly installed on the upper surface of the fixed base plate 1. A shaft seat 28 is fixedly connected to the upper surface of the fixed base plate 1, and a caster wheel 2 is fixedly connected to the lower surface of the fixed base plate 1.

[0028] It also includes a rotating mechanism, which includes a drive shaft 29 fixedly mounted on the output end of the servo motor 6, a mounting plate 4, and a mounting base 5 fixedly mounted on the front surface of the mounting plate 4. The drive shaft 29 extends through to the front of the shaft base 28 and is fixedly connected to the rear surface of the mounting plate 4.

[0029] Specifically, after the servo motor 6 starts, the drive shaft 29 on the drive output end rotates. The drive shaft 29 passes through the shaft seat 28 and is fixedly connected to the rear surface of the mounting plate 4, thereby driving the mounting plate 4 to rotate around the shaft seat 28. The mounting seat 5 on the front surface of the mounting plate 4 rotates accordingly, thereby adjusting the direction of the clamping mechanism so that the clamping mechanism can be aligned with the part of the tank to be inspected, making it easier for the scanning equipment to scan from above.

[0030] The clamping mechanism includes a second mounting plate 9 fixedly mounted on the mounting base 5, a second servo motor 30 fixedly mounted on the rear surface of the second mounting plate 9, a first slide 11, and a second slide 3. A rail 12 is fixedly connected to the front surface of the second mounting plate 9. A second drive shaft 31 is fixedly connected to the output end of the second servo motor 30. The second drive shaft 31 extends through to the front of the second mounting plate 9 and is fixedly connected to a rotating plate 8. A first connecting rod 32 is rotatably connected to one end of the rotating plate 8, and a second connecting rod 7 is rotatably connected to the other end. The end of the first connecting rod 32 away from the rotating plate 8 is rotatably connected to the middle position of the first slide 11, and the end of the second connecting rod 7 away from the rotating plate 8 is rotatably connected to the middle position of the second slide 3.

[0031] The rear surfaces of slide 11 and slide 3 are both fixedly connected to a card seat 10 that slides on the card rail 12. The front surfaces of slide 11 and slide 3 are both fixedly connected to a fixing plate 14 that is perpendicular to the mounting plate 9. The front surface of the fixing plate 14 is fixedly connected to a buffer spring 17. The front end of the buffer spring 17 is fixedly connected to a clamping plate 18. The front surface of the clamping plate 18 is provided with an arc groove 16. The front surface of the fixing plate 14 is fixedly connected to a baffle 13 and a limiting plate 15. The limiting plate 15 is located on the upper and lower sides of the clamping plate 18.

[0032] Specifically, after the servo motor 2 30 is started, the drive shaft 2 31 on the drive output end rotates. The drive shaft 2 31 drives the rotating plate 8 to rotate. The rotating plate 8 pushes the slide block 1 11 and slide block 2 3 to slide on the clamping rail 12 through the connecting rod 1 32 and the connecting rod 2 7 respectively. The slide block 1 11 and slide block 2 3 move along the clamping rail 12 through the clamping seat 10 to achieve opposite or opposite movement. The fixing plate 14 on the front surface of the slide block 1 11 and slide block 2 3 moves accordingly. The buffer spring 17 on the front surface of the fixing plate 14 pushes the clamping plate 18 to contact the surface of the tank. The arc groove 16 on the front surface of the clamping plate 18 adapts to the curvature of the tank. The buffer spring 17 provides buffering force to ensure stable clamping without damaging the tank. The baffle 13 and the limiting plate 15 limit the range of motion of the clamping plate 18 to ensure stable clamping, thereby fixing the tank in the center position for easy inspection by the scanning equipment above.

[0033] In addition, servo motor 16 and servo motor 230 can be high-precision AC servo motors from the Panasonic MINASA series. They drive the rotor to rotate precisely according to the control signal and form a closed-loop control by real-time feedback of position through the built-in encoder, thereby achieving precise angle, speed or torque output.

[0034] The lifting mechanism includes a lifting guide rail 25 fixedly connected to the upper surface of the fixed base plate 1 and a U-shaped placement platform 27. The lifting guide rail 25 is symmetrically distributed on both sides of the U-shaped placement platform 27. The inner wall of the lifting guide rail 25 is provided with a vertical slide groove 20. The lower end of the lifting guide rail 25 is fixedly connected to a bidirectional motor 26. The output end of the bidirectional motor 26 is threadedly connected to a screw slider 21 through a vertical screw 19. The screw slider 21 slides on the vertical slide groove 20 and is fixedly connected to the U-shaped placement platform 27. The lower inner wall of the U-shaped placement platform 27 is fixedly connected to a buffer spring 23. The upper end of the buffer spring 23 is fixedly connected to a placement plate 24. The upper surface of the placement plate 24 is provided with an arc groove 22, and both sides abut against the inner side walls of the U-shaped placement platform 27.

[0035] Specifically, after the bidirectional motor 26 starts, the drive output rotates through the vertical lead screw 19, causing the lead screw slider 21 to slide up and down within the vertical slide groove 20. The lead screw slider 21 is fixedly connected to the U-shaped placement platform 27, thereby driving the U-shaped placement platform 27 to rise and fall as a whole. The buffer spring 23 inside the U-shaped placement platform 27 supports the placement plate 24. The arc-shaped groove 22 on the upper surface of the placement plate 24 adapts to the shape of the bottom of the tank, and its two sides abut against the inner side wall of the U-shaped placement platform 27 to ensure the stability of the tank. The lifting mechanism adjusts the height of the tank so that the detection part of the tank is in a suitable position, facilitating scanning by the scanning equipment from above.

[0036] In addition, the bidirectional motor 26 can be a SEWDRN series worm gear reducer motor; its basic principle is to control the forward and reverse rotation of the motor output shaft by changing the phase sequence of the input power supply, thereby driving the lead screw to realize the bidirectional, self-locking lifting motion of the lifting platform.

[0037] Working Principle: First, the atmospheric pressure storage tank to be inspected is placed on the placement plate 24 of the lifting mechanism. The arc-shaped groove 22 and the buffer spring 23 work together to provide initial positioning and cushioning. Then, the bidirectional motor 26 is started, driving the U-shaped placement platform 27 to rise to a suitable height along the lifting guide rail 25 via the transmission of the vertical lead screw 19 and the lead screw slider 21. Next, the servo motor 6 drives the mounting plate 4 and the entire clamping mechanism to rotate via the drive shaft 29, aligning it with the area to be inspected on the tank. Then, the servo motor 30 is started, driving the rotating plate 8 to rotate via the drive shaft 31. This, in turn, pushes the slide blocks 11 and 3 along the clamping rail 12 in opposite directions via connecting rods 32 and 7, allowing the two clamping plates 18 to firmly clamp the tank from both sides under the cushioning effect of the buffer spring 17. Finally, the tank is reliably fixed in the center of the device, providing a stable and accurate inspection platform for the scanning equipment above.

[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
