Description

Technical Field

[0001] This utility model relates to the technical field of non-destructive testing equipment for steel pipes, and in particular to a system for taking and retrieving steel pipe flaw detection comparison sample tubes. Background Technology

[0002] Steel pipes are core components in oil and gas transportation, municipal engineering, aerospace, and other fields, and their quality directly determines the safety and operational efficiency of projects. In the oil and gas industry, internal cracks and surface defects in steel pipes can easily lead to leaks, fires, or even explosions during high-pressure transportation. Therefore, flaw detection has become a mandatory step in steel pipe production. Steel pipe flaw detection uses a sample pipe as a benchmark, and non-destructive testing techniques are used to identify defects in the steel pipe to be inspected. However, existing methods for sample pipe removal and retrieval have significant limitations.

[0003] The traditional method relies on overhead cranes to transport sample tubes, which requires dedicated personnel to operate and takes a long time to pick up and place a single sample tube, resulting in a low degree of automation. At the same time, the sample tubes are prone to shaking and collision during the hoisting process, posing serious safety hazards.

[0004] Therefore, it is necessary to propose a steel pipe flaw detection comparison sample tube placement and retrieval system to solve at least one of the above problems.

[0005] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this application and facilitating understanding by those skilled in the art.

The device includes a material feeding component and a drive mechanism that is pulsatingly connected to the material feeding component. The drive mechanism can drive the material feeding component to switch between a first position and a second position. The first position is higher than the second position. When the material feeding component is in the first position, it cooperates with the storage wheel to stop the sample tube in the storage wheel. When the required sample tube in the storage wheel rotates to a predetermined position, the material feeding component is in the second position, and the required sample tube can slide onto the rotating wheel support mechanism.

[0008] In a preferred embodiment, there are multiple storage discs, which are spaced apart along the axial direction of the sample tube. The driving mechanism includes a driving source, a transmission component connected to the driving source, and a deflector shaft connected to the transmission component.

One end of each deflector is connected to the deflector shaft. The driving force generated by the driving source is transmitted to each deflector through the transmission component and the deflector shaft.

[0009] In a preferred embodiment, the rotary wheel support mechanism includes a plurality of rotary wheel arc-shaped support members, the number of which is adapted to the number of the storage wheel. For the storage wheel at the same position, when the deflector is in the second position, the stop surface of the deflector is not higher than the support surface of the rotary wheel arc-shaped support member.

[0010] In a preferred embodiment, along the axial direction of the deflector shaft, the deflector component is disposed adjacent to the rotary wheel arc-shaped support component, and the stop surface of the deflector component is configured to mimic the contour of the support surface of the rotary wheel arc-shaped support component.

[0011] In a preferred embodiment, the deflector is plate-shaped, with a first mounting hole at one end. The deflector is sleeved on the deflector shaft through the first mounting hole, and a first transition member for transmitting torque is provided at the hole-shaft mating position between the deflector and the deflector shaft.

The transmission system drives the storage wheel to rotate, and a storage section is provided on the periphery of the storage wheel to accommodate the sample tubes. Under the drive of the driving mechanism, the deflector mechanism can switch between a first position (high position) and a second position (low position). In the high position, the sample tube is stopped. After the target sample tube is in place, it is switched to the low position, allowing the sample tube to slide to the rotary wheel support mechanism. This completely replaces manual hoisting operations, eliminates the safety hazards of sample tube shaking and collision, and significantly improves operational safety. The directional flow of the sample tube is achieved by switching the position of the deflector mechanism, avoiding interference from non-target sample tubes, and the retrieval accuracy reaches 100%. The rotary design of the storage wheel allows for the centralized storage of sample tubes of multiple specifications, laying the foundation for subsequent non-stop changeover and effectively shortening the changeover preparation time.

[0024] To address the issues of manual operation, existing technologies have proposed placing single-specification sample tubes on a storage rack and automatically retrieving them via a rotary arm. While this improves safety, the storage structure is only compatible with specific sample tube specifications. Switching between different steel pipe models requires machine downtime for sample replacement, and the changeover time remains relatively long, leading to a decrease in the effective operating rate of the production line and failing to meet the needs of multi-specification, small-batch production. Therefore, there is an urgent need for a sample tube retrieval and recovery system that balances automation, multi-specification compatibility, and production continuity.

[0025] This utility model provides a steel pipe flaw detection comparison sample tube placement and recovery system, which can realize automated storage, accurate material selection, stable flow and safe recovery of sample tubes. At the same time, it is compatible with the switching of multiple specification sample tubes, and the changeover can be completed without stopping the machine, thereby improving the efficiency and safety of the flaw detection process.

[0026] Please refer to the following for comprehensive information. Figures 1 to 5 This application specification provides a steel pipe flaw detection comparison sample tube placement and retrieval system. The system may include: a transmission system, a storage wheel 5, a deflector mechanism, and a rotary wheel support mechanism. The transmission system is connected to the storage wheel 5 and drives its rotation. The storage wheel 5 includes a rotating wheel body 51 with a storage section 52 on its periphery for accommodating sample tubes 6. The rotary wheel support mechanism is located on one side of the storage wheel 5. The deflector mechanism... The material feeding mechanism includes a material stop 10 and a drive mechanism that is pulsatingly connected to the material stop 10. The drive mechanism can drive the material stop 10 to switch between a first position and a second position. The first position is higher than the second position. When the material stop 10 is in the first position, the material stop 10 cooperates with the storage wheel 5 to stop the sample tube 6 in the storage wheel 5. When the required sample tube 6 in the storage wheel 5 rotates to the predetermined position, the material stop 10 is in the second position, and the required sample tube 6 can slide onto the rotating wheel support mechanism.

[0027] The steel pipe flaw detection comparison sample tube retrieval and recovery system provided in this application embodiment includes a transmission system, a storage wheel 5, a material blocking mechanism, and a rotary wheel support mechanism; the transmission system drives the storage wheel 5 to rotate, and a storage section 52 is provided on the circumference of the storage wheel 5 to accommodate the sample tube 6; under the drive of the driving mechanism, the material blocking component 10 of the material blocking mechanism can be in a first position (e.g., Figure 2 and Figure 3 The relative high position shown) and the second position (as shown) Figure 4 and Figure 5 The switching between the relatively low and high positions is as shown. When the high position is reached, the stop tube 6 is stopped. After the target tube 6 is in place, the switch is made to the low position, so that the tube 6 slides to the rotary wheel support mechanism. This can completely replace the manual hoisting operation, eliminate the safety hazards of the tube 6 shaking and colliding, and significantly improve the safety of operation. The directional flow of the tube 6 is realized by the position switching of the stop and guide component 10, avoiding interference from non-target tubes 6, and the material picking accuracy reaches 100%. The rotary design of the storage wheel 5 allows for the centralized storage of multiple specifications of tubes 6, laying the foundation for subsequent non-stop changeover and effectively shortening the changeover preparation time.

[0028] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] The steel pipe flaw detection comparison sample tube taking and retrieval system may include: a transmission system, a material storage wheel 5, a material blocking and shifting mechanism, and a rotary wheel support mechanism.

[0030] The storage wheel 5 is a plurality of such storage wheels 5, which are spaced apart along the axial direction of the sample tube 6. The driving mechanism includes a driving source, a transmission component connected to the driving source, and a deflecting shaft 11 connected to the transmission component. The extension direction of the deflecting shaft 11 is consistent with the extension direction of the sample tube 6. The number of deflecting components 10 is adapted to the number of storage wheels 5. One end of each deflecting component 10 is connected to the deflecting shaft 11. The driving force generated by the driving source is transmitted to each deflecting component 10 through the transmission component and the deflecting shaft 11.

[0031] In this embodiment, the number of the storage wheel 5 can be determined according to the length of the sample tube 6. Specifically, this application does not make a specific limit on the number of the storage wheel 5.

[0032] In this embodiment, multiple storage discs 5 are spaced apart along the axial direction of the sample tube 6. The driving mechanism includes a driving source, a transmission component, and a deflecting shaft 11 (extending in the same direction as the sample tube 6). The number of deflecting components 10 is adapted to the storage discs 5. The driving force is synchronously transmitted to each deflecting component 10 through the transmission component and the deflecting shaft 11. The multiple storage discs 5 distributed along the axial direction of the sample tube 6 can form multi-point support for the long sample tube 6, preventing the sample tube 6 from bending and deforming due to its own weight, and improving the placement stability of the sample tube 6. A single driving source synchronously controls multiple deflecting components 10 through the deflecting shaft 11, ensuring that the deflecting actions at each position are fully coordinated, avoiding the sample tube 6 from jamming or shifting due to asynchronous actions, and improving the reliability of circulation. Compared with independent control by multiple driving sources, the structure is simpler and the equipment maintenance cost is lower.

[0033] Furthermore, the rotary wheel support mechanism includes multiple rotary wheel arc-shaped support members 8, the number of which is adapted to the number of the storage wheel 5. For the storage wheel 5 at the same position, when the deflector 10 is in the second position, the stop surface of the deflector 10 is not higher than the support surface of the rotary wheel arc-shaped support member 8.

[0034] In this embodiment, the rotary wheel support mechanism includes multiple rotary wheel arc-shaped support members 8, the number of which is adapted to the storage wheel 5; such as Figure 4 and Figure 5 As shown, when the stopper 10 is in the second position (low position), its stop surface is not higher than the support surface of the arc-shaped support.

[0035] By having arc-shaped supports corresponding one-to-one with the storage wheel 5, support points matching the outer circle of the sample tube 6 are formed, increasing the contact area of ​​the sample tube 6 during sliding, resulting in more uniform pressure distribution and avoiding damage to the sample tube 6 caused by local compression. In addition, the design that the stop surface is not higher than the support surface eliminates the height difference obstacle of the sample tube 6's flow, making the sliding of the sample tube 6 from the storage wheel 5 to the support mechanism smoother, eliminating the risk of jamming, and helping to shorten the single flow time.

[0036] In one embodiment, along the axial direction of the deflector shaft 11, the deflector 10 is disposed adjacent to the rotary wheel arc support 8, and the stop surface of the deflector 10 is configured to mimic the contour of the support surface of the rotary wheel arc support 8.

[0037] In this embodiment, along the axial direction of the deflector shaft 11, the deflector component 10 and the arc-shaped support component are arranged adjacent to each other, and the stop surface of the deflector component 10 is contoured to the support surface of the support component. Specifically, the stop surface of the deflector component 10 can be a V-shaped structure formed by splicing two inclined surfaces (the larger one being the main stop surface 541 and the smaller one being the auxiliary stop surface 542). The included angle of this V-shape can be an obtuse angle, which facilitates the limiting of sample tubes 6 with different diameters. The adjacent arrangement of the deflector component 10 and the rotary wheel arc-shaped support component 8 helps to shorten the flow path of the sample tube 6, further improves the flow efficiency, and reduces the attitude deviation of the sample tube 6 during flow.

[0038] In one embodiment, the deflector 10 is plate-shaped, and a first mounting hole is provided at one end of the deflector 10. The deflector 10 is sleeved on the deflector shaft 11 through the first mounting hole, and a first transition member for transmitting torque is provided at the hole-shaft mating position of the deflector 10 and the deflector shaft 11.

[0039] In this embodiment, the first transition piece can be a flat key, which is used to realize the rigid connection between the stop and the shaft. Compared with a simple interference fit, the torque transmission using the first transition piece can avoid slippage caused by wear after long-term use. The plate-shaped stop and the stop piece 10 is easy to process and has a large stop surface area, which makes the stop stability of the sample tube 6 stronger and the slippage rate of non-target sample tube 6 can be controlled.

[0040] In one embodiment, the driving source may include a hydraulic cylinder 7, and the transmission component includes a transmission plate 12. One end of the transmission plate 12 is hinged to the driving end of the hydraulic cylinder 7, and the other end of the transmission plate 12 is provided with a second mounting hole. The transmission plate 12 is sleeved on the deflector shaft 11 through the second mounting hole, and the transmission plate 12 and the deflector shaft 11 are provided with a second transition component for transmitting torque at the hole-shaft mating position.

[0041] In this embodiment, when the drive source is a hydraulic cylinder 7, its output force is more stable and its adjustment accuracy is higher, which helps to shorten the position switching response time of the deflector 10 and reduce high and low position positioning errors. One end of the transmission plate 12 is hinged to the hydraulic cylinder 7, which allows the transmission plate 12 to adapt to the angle change with the extension and retraction of the hydraulic cylinder 7, avoiding stress concentration caused by rigid connection and extending the service life of the mechanism. The second transition component, such as a flat key, ensures lossless transmission of driving force and more precise deflection action.

[0042] In one embodiment, the transmission system includes: a transmission shaft 9 for passing through and drivingly connected to the storage wheel 5; a motor 1 for providing rotational force; a brake 2 for braking; a reducer 3 for reducing torque; and a coupling 4 for transmitting the force from the motor 1 to the transmission shaft 9 after being driven by the reducer 3.

[0043] In this embodiment, the combination of motor 1, reducer 3, and coupling 4 forms a stable power chain. Specifically, motor 1 can be a 5.5kW servo motor, and reducer 3 can be a reducer with a 1:50 reduction ratio, which can precisely control the speed of the storage wheel 5 and ensure the positioning accuracy of the sample tube 6. The brake 2 can be an electromagnetic brake 2, which has a short braking response and can brake instantly after the target sample tube 6 is in place, avoiding position deviation caused by the inertial rotation of the wheel. The rigid transmission shaft 9 has high transmission efficiency, low power loss, and low equipment energy consumption.

[0044] In one embodiment, there are multiple storage sections 52, which are evenly spaced along the circumference of the wheel body 51.

[0045] In this embodiment, multiple storage sections 52 are evenly distributed around the circumference of the wheel body 51. Specifically, the number of storage sections 52 can be 6, 7, 8, 9, 10, 11, 12, or more or fewer, enabling centralized storage of sample tubes 6 of various specifications. The evenly distributed storage sections 52 balance the forces on the wheel body 51, reduce the vibration amplitude during rotation, and improve the operational stability of the equipment.

[0046] In one specific embodiment, the storage part 52 is a groove formed inward from the outer edge of the wheel body 51, and the groove is a slot whose dimensions decrease from the outside to the inside along the radial direction.

[0047] In this embodiment, the storage section 52 can specifically be a groove formed inward from the outer edge of the wheel body 51, and the groove reduces in size radially from the outside to the inside to form a slot. Overall, the groove structure is easy to process and has a high degree of fit with the sample tube 6, and can be adapted to the outer circle contour of sample tubes 6 with different diameters, without the need to customize the storage structure for a single specification.

[0048] Furthermore, a liner 53 is provided on the surface of the groove. Specifically, the liner 53 can be made of materials such as rubber or polyurethane. Of course, the specific material of the liner 53 can also be other forms, and is not limited to the above description. Those skilled in the art may make other changes under the guidance of the technical essence of this application, but as long as the function and effect achieved are the same as or similar to this application, they should be covered within the protection scope of this application.

[0049] By setting a liner 53 on the surface of the groove, the hard contact between the sample tube 6 and the metal slot can be buffered, and the surface of the sample tube 6 can be prevented from being scratched due to collision. In addition, the liner 53 can increase the friction between the sample tube 6 and the slot, further preventing the sample tube 6 from moving during rotation. At the same time, by replacing the liner 53 with different thicknesses, more specifications of sample tubes 6 can be adapted, and the equipment compatibility can be further improved.

[0050] In a specific application scenario, three storage wheel discs 5 are installed at intervals on the drive shaft 9 according to the length of the sample tube 6 (e.g., 6m). The storage wheel disc 5 has six V-shaped grooves evenly machined around its circumference (radial reduction angle 60°), and a 5mm thick polyurethane pad 53 is pasted inside the grooves. A rotary wheel arc support 8 (lined with a rubber buffer layer) is set for each storage wheel disc 5, and the distance between the rotary wheel arc support 8 and the edge of the disc is controlled at about 5mm.

[0051] Three plate-shaped deflector components 10 are fixed to the shaft by flat keys; one end of the transmission plate 12 is hinged to the drive end of the hydraulic cylinder 7, and the other end is connected to the deflector shaft 11 by a flat key, forming a power transmission chain. In the transmission system, the 5.5kW servo motor 1 is connected to the transmission shaft 9 via the planetary reducer 3 (1:50) and the flexible coupling 4. The transmission shaft 9 passes through the storage wheel 5 and is connected to the transmission via a key.

[0052] The workflow of the steel pipe flaw detection comparison sample tube removal and retrieval system provided in this application is as follows: Storage: 50- Sample tubes 6 of different specifications with a diameter of 300mm are placed into the grooves of the storage wheel 5, and the pads 53 and the V-groove are used to fix the sample tubes 6. Material handling: The control system receives the flaw detection specification command, drives the drive motor 1 to rotate the storage wheel 5, and after the position sensor detects the target sample tube 6 at the work station, the brake 2 brakes instantly; the hydraulic cylinder 7 drives the deflector shaft 11 to rotate, so that the deflector component 10 switches from a high position (for example, the main stop surface 541 is about 90° with the horizontal plane) to a low position (for example, the main stop surface 541 is about -15° with the horizontal plane), and its stop surface is lower than the support surface of the arc-shaped support component. The sample tube 6 slides into the rotating wheel arc-shaped support component 8 along the contour; Transfer: The rotary arm transfers sample tube 6 to the flaw detection station; Recovery: After flaw detection is completed, the rotary arm sends the sample tube 6 back to the support, the hydraulic cylinder 7 drives the stop and pusher 10 to reset to the high position, and pushes the sample tube 6 back to the groove of the storage wheel 5, completing one cycle.

[0053] Overall, the aforementioned steel pipe flaw detection comparison sample tube retrieval and recovery system achieves fully automated processes for sample tube retrieval, transfer, and recovery, significantly reducing labor costs. In terms of efficiency, the processing time for a single sample tube is reduced to less than 15 seconds, greatly improving the effective operating rate of the production line. Regarding safety and reliability, it eliminates the safety hazards of manual operation, reducing the sample tube damage rate to below 0.1%, and ensuring stable flaw detection accuracy. In terms of economy, multi-specification compatibility reduces equipment investment, structural optimization lowers maintenance costs, and the annual comprehensive benefits of a single production line are significantly improved.
