Description
Technical Field
[0001] This invention relates to the field of stainless steel corrugated pipe inspection and control technology, and in particular to an optical control support arm for stainless steel corrugated pipe processing and inspection. Background Technology
[0002] Stainless steel corrugated pipes, with their excellent flexibility, pressure resistance, and corrosion resistance, are widely used in various fields such as construction, chemical industry, energy, and machinery. Their quality is directly related to the safety and reliability of various pipeline systems. Therefore, during the processing, it is necessary to strictly inspect the inner and outer walls to check for defects such as cracks, dents, uneven wall thickness, and oxide scale, so as to ensure that the products meet the requirements of relevant standards such as GB / T12777-2019.
[0003] Currently, the internal and external wall inspection during the processing of stainless steel corrugated pipes mostly adopts an online conveyor-type inspection mode. This mode involves using a conveyor device to move the entire corrugated pipe while simultaneously scanning and inspecting for defects on the internal and external walls. This method allows for continuous integration of inspection and processing, improving production efficiency. However, existing conveyor-type inspection devices suffer from significant instability, making it difficult to simultaneously ensure the overall movement and posture stability of the corrugated pipe.
[0004] Existing conveying mechanisms mostly use simple roller clamping or belt conveying. Due to the multi-layered curved structure and unique corrugation of stainless steel corrugated pipes, excessive clamping force can easily cause surface deformation, while insufficient clamping force can lead to slippage, axial movement, or radial swaying during conveying. This instability can cause the relative position of the detection probe to shift between the inner and outer walls of the corrugated pipe, making it impossible to guarantee detection coverage and accuracy. This can easily lead to missed or false detections and make it difficult to accurately identify hidden defects such as tiny cracks.
[0005] Furthermore, insufficient stability can lead to decreased testing efficiency, increased rework costs, and even allow substandard products to enter the market, creating safety hazards such as pipeline leaks and structural failures. Currently, there is no effective solution in existing technologies that can significantly improve the stability of the conveying and testing process while ensuring the continuous movement of the stainless steel corrugated pipe, thus meeting the requirements for high-precision testing. Therefore, solving the stability problem in the conveying and testing process of stainless steel corrugated pipes has become a critical technical bottleneck that urgently needs to be overcome in the current field of stainless steel corrugated pipe processing and testing. Summary of the Invention
[0006] The technical problem to be solved by the present invention is that the existing technology for stainless steel corrugated pipe conveying and testing suffers from insufficient stability, low detection accuracy, and is prone to missed detection and false detection.
[0007] The technical solution adopted by this invention to solve its technical problem is: an optical control support arm for processing and inspection of stainless steel corrugated pipes, including a mounting frame, a vertical control backplate fixedly mounted on the rear side of the upper surface of the mounting frame, an embedded horizontal guide rail fixedly mounted on the vertical control backplate, an electrically controlled upper conveyor belt and an electrically controlled lower conveyor belt coaxially mounted inside the embedded horizontal guide rail, several electrically controlled support arms hinged to the outside of the electrically controlled upper conveyor belt, electrically controlled struts for controlling the electrically controlled support arms hinged to the outside of the electrically controlled lower conveyor belt, and an optical inspection module mounted on the side wall of the electrically controlled support arm.
[0008] The electrically controlled upper conveyor belt includes an upper driven wheel, an upper drive wheel, and an upper conveyor belt body, all movably mounted on both ends of the embedded horizontal guide rail. The electrically controlled lower conveyor belt includes a lower driven wheel, a lower drive wheel, and a lower conveyor belt body, all movably mounted on both ends of the embedded horizontal guide rail. A main drive motor for driving the lower drive wheel is fixedly installed on one side of the lower end of the embedded horizontal guide rail. The upper and lower driven wheels are coaxially fixed, as are the upper and lower drive wheels, ensuring that the electrically controlled upper and lower conveyor belts operate synchronously and coaxially, avoiding motion deviation.
[0009] Rigid mounting plates are fixedly installed on the outer surfaces of both the upper and lower conveyor belt bodies, providing a stable mounting foundation for the electrically controlled support arms and electrically controlled struts, and preventing deformation of the conveyor belt during operation from affecting installation stability. The electrically controlled support arm includes a tilting adjustment arm hinged to the rigid mounting plate on the surface of the upper conveyor belt body, an external telescopic rod slidably inserted into the inner side of the tilting adjustment arm, an arc-shaped support frame fixed to the extended end of the external telescopic rod, a quick-release frame assembled on the arc-shaped support frame, and an adjustment strut fixed inside the tilting adjustment arm. The support posture and support range can be flexibly adjusted according to the specifications of the stainless steel corrugated pipe, adapting to the inspection needs of corrugated pipes of different sizes.
[0010] The electrically controlled strut is hinged to a rigid mounting plate on the surface of the lower conveyor belt. The extended end of the strut is movably assembled with the outer side of the tilting adjustment arm. By extending and retracting the strut, the tilting angle of the adjustment arm is adjusted, thereby adjusting the support posture of the arc-shaped support frame on the bellows and ensuring support stability. Lateral transition openings are provided inside the vertical control back panel on both sides of the embedded horizontal guide rail, facilitating the entry and exit of the bellows and observation and maintenance during the inspection process.
[0011] A sliding mounting base for installing the optical inspection module is slidably fitted on the outer wall of the tilting adjustment arm. Lateral locking bolts are threaded onto the side wall of the sliding mounting base, allowing adjustment and locking of the optical inspection module's installation position according to inspection requirements, ensuring comprehensive inspection coverage. A lateral limiting plate is installed inside the opening of the embedded horizontal guide rail to limit the rigid mounting plate, preventing it from shifting during operation and ensuring the stability of the conveyor belt. An optical positioning control module is installed at the end of the embedded horizontal guide rail, which can monitor the position of the bellows in real time, precisely control the conveying speed and inspection rhythm, further improving inspection accuracy.
[0012] The beneficial effects of this invention are: (1) An optical control support arm for processing and inspection of stainless steel corrugated pipes according to the present invention, through the coaxial synchronous operation of an electrically controlled upper conveyor belt and an electrically controlled lower conveyor belt, and the support posture of the electrically controlled support arm is controlled by an electrically controlled strut, so as to achieve stable support and continuous conveying of stainless steel corrugated pipes, effectively solving the problems of slippage, swaying and shaking of existing conveying and inspection devices; (2) The electrically controlled support arm can be flexibly adjusted to fit different specifications of corrugated pipes. The arc-shaped support frame fits the curved surface structure of the corrugated pipe, avoiding compression deformation while ensuring support stability. (3) The optical detection module can be flexibly adjusted in position. Through laser detection, image analysis and closed-loop control, it can capture abnormal bending at the bottom of the corrugated pipe in real time, dynamically control the adjacent electric control struts to drive the support arm to flip, reduce the support gap, and continuously ensure the support stability. (4) The optical positioning control module can monitor the movement position of the electric control arm and the electric control support rod in real time. When the two move to the end of the embedded horizontal guide rail, the optical positioning is triggered and the two are reset and attached to ensure that the stainless steel corrugated pipe passes smoothly from the side transition port, avoids obstruction of passage, and improves the smoothness of device operation. (5) The optical detection module and the optical positioning control module work together to ensure the relative position of the detection probe and the inner and outer walls of the corrugated pipe is stable, improve the detection accuracy and coverage, reduce the phenomenon of missed detection and false detection, and realize the seamless connection of transportation, detection and passage. The overall structure design is reasonable, improves production efficiency, reduces rework costs, avoids unqualified products from entering the market, and eliminates pipeline operation safety hazards.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.
[0019] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0020] Figure 1 , Figure 2 and Figure 3 The optical control support arm shown is used for the processing and inspection of stainless steel corrugated pipes. It includes a mounting frame 1, which serves as the foundation for the entire device, ensuring its overall stability. A vertical control backplate 2 is fixedly mounted on the rear side of the upper surface of the mounting frame 1. The vertical control backplate 2 is used to mount an embedded horizontal guide rail 3, providing support for subsequent components. The embedded horizontal guide rail 3 is fixedly mounted on the vertical control backplate 2. An electrically controlled upper conveyor belt 4 and an electrically controlled lower conveyor belt 5, which move coaxially with the embedded horizontal guide rail 3, are movably mounted inside the embedded horizontal guide rail 3. The electrically controlled upper conveyor belt 4 and the electrically controlled lower conveyor belt 5 operate synchronously, ensuring the stability of the conveying process.
[0021] The electrically controlled upper conveyor belt 4 includes an upper driven wheel 41, an upper drive wheel 42, and an upper conveyor belt body 43, which are movably installed at both ends of the inner side of the embedded horizontal guide rail 3. The electrically controlled lower conveyor belt 5 includes a lower driven wheel 51, a lower drive wheel 52, and a lower conveyor belt body 53, which are movably installed at both ends of the inner side of the embedded horizontal guide rail 3. A main drive motor 9 for driving the lower drive wheel 52 is fixedly installed on one side of the lower end of the embedded horizontal guide rail 3. When the main drive motor 9 is working, it drives the lower drive wheel 52 to rotate. Since the upper drive wheel 42 and the lower drive wheel 52 are coaxially fixed, and the upper driven wheel 41 and the lower driven wheel 51 are coaxially fixed, the rotation of the lower drive wheel 52 will synchronously drive the upper drive wheel 42 to rotate, thereby driving the electrically controlled upper conveyor belt 4 and the electrically controlled lower conveyor belt 5 to run synchronously and coaxially, avoiding motion deviation.
[0022] Rigid mounting plates 10 are fixedly installed on the outer surfaces of both the upper conveyor belt body 43 and the lower conveyor belt body 53. The rigid mounting plates 10 are made of high-strength metal and provide a stable mounting base for the electrically controlled support arms 6 and electrically controlled struts 7, preventing deformation of the conveyor belt during operation and thus preventing displacement of the mounted components. Several electrically controlled support arms 6 are hinged to the outer surface of the electrically controlled upper conveyor belt 4. The electrically controlled support arms 6 support the stainless steel corrugated pipe. Electrically controlled struts 7 are hinged to the outer surface of the electrically controlled lower conveyor belt 5 to control the electrically controlled support arms 6. The posture of the electrically controlled support arms 6 is adjusted by extending and retracting the electrically controlled struts 7.
[0023] The electrically controlled support arm 6 includes a tilting adjustment arm 61 hinged to a rigid mounting plate 10 on the surface of the upper conveyor belt body 43, an external telescopic rod 62 slidably inserted into the inside of the tilting adjustment arm 61, an arc-shaped support frame 63 fixed to the extended end of the external telescopic rod 62, a quick-release frame 64 assembled on the arc-shaped support frame 63, and an adjusting strut 65 fixed inside the tilting adjustment arm 61. The tilting adjustment arm 61 can tilt around the hinge point, the external telescopic rod 62 can slide inside the tilting adjustment arm 61 to adjust the extension length of the arc-shaped support frame 63. The arc-shaped support frame 63 conforms to the curved surface structure of the stainless steel corrugated pipe. The quick-release frame 64 is easy to disassemble and replace, adapting to corrugated pipes of different specifications. The adjusting strut 65 can help fix the position of the external telescopic rod 62 to ensure support stability.
[0024] The electrically controlled support rod 7 is hinged to the rigid mounting plate 10 on the surface of the lower conveyor belt body 53. The extended end of the electrically controlled support rod 7 is movably assembled with the outer side of the tilting adjustment arm 61. When the electrically controlled support rod 7 extends or retracts, it can push the tilting adjustment arm 61 to tilt around the hinge point, thereby adjusting the support angle of the arc-shaped support frame 63 on the corrugated pipe, ensuring that the corrugated pipe is stable in posture during the conveying process and does not slip or shake. The vertical control back panel 2 has lateral transition ports 11 on both sides of the embedded horizontal guide rail 3. The lateral transition ports 11 facilitate the entry and exit of the stainless steel corrugated pipe into and out of the device, and also facilitate the observation and inspection process and maintenance by the staff.
[0025] A sliding mounting base 12 for installing the optical detection module 8 is slidably fitted on the outer wall of the tilting adjustment arm 61. The sliding mounting base 12 can slide along the tilting adjustment arm 61 to adjust the installation position of the optical detection module 8. A lateral locking bolt 13 is threaded on the side wall of the sliding mounting base 12. After the position of the sliding mounting base 12 is adjusted, tightening the lateral locking bolt 13 will fix it and ensure that the optical detection module 8 does not shift during the detection process. A lateral limiting plate 14 for limiting the rigid mounting plate 10 is installed inside the opening of the embedded horizontal guide rail 3. The lateral limiting plate 14 can limit the left and right movement of the rigid mounting plate 10 to prevent it from shifting during the operation of the conveyor belt and ensure the stability of the operation of the electrically controlled upper conveyor belt 4 and the electrically controlled lower conveyor belt 5.
[0026] An optical positioning control module 15 is installed at the end of the embedded horizontal guide rail 3. Its core function is to monitor the movement position of the electrically controlled support arm 6 and the electrically controlled strut 7. When the electrically controlled support arm 6 and the electrically controlled strut 7 move to one side of the embedded horizontal guide rail 3 along with the electrically controlled upper conveyor belt 4 and the electrically controlled lower conveyor belt 5, the optical positioning control module 15 triggers optical positioning and then sends a control signal to the main control system. The main control system controls the electrically controlled support arm 6 and the electrically controlled strut 7 to reset and fit together, reduce the support spacing, and adjust the support posture to ensure that the stainless steel corrugated pipe can pass smoothly from the side transition port 11 and avoid the corrugated pipe from being obstructed due to the protrusion of the support arm or strut.
[0027] The optical detection module 8 detects the bending degree at the bottom of the stainless steel corrugated pipe and controls the adjacent electrically controlled support rod 7 to drive the electrically controlled bracket 6 to rotate and reduce the support gap. The specific optical technology implementation process is as follows: The optical detection module 8 has a built-in laser emitter, CMOS image sensor, filter, and embedded signal processing unit. It is fixed on the rotating adjustment arm 61 by a sliding mounting base 12. The installation position corresponds to the bottom support area of the stainless steel corrugated pipe and forms a triangular detection layout with the support points of the two adjacent electrically controlled brackets 6 to ensure accurate capture of the bending deformation at the bottom of the corrugated pipe and the change in the support gap. During operation, the laser emitter continuously emits a visible laser with a wavelength of 650nm towards the bottom of the stainless steel corrugated pipe. The laser beam is perpendicularly irradiated on the corrugated surface at the bottom of the pipe. Due to the natural curvature at the bottom of the corrugated pipe and the fact that an excessively large support gap will cause abnormal local bending (the larger the gap, the more obvious the local bending deviation), diffuse reflection will occur after laser irradiation. After the reflected light is filtered out by the filter to remove ambient stray light, it is received by the CMOS image sensor and converted into an electrical signal.
[0028] After the CMOS image sensor converts the acquired light signal into a digital image signal, it transmits it to the embedded signal processing unit built into the optical detection module 8. This unit analyzes and processes the image signal using an optical triangulation algorithm: First, it extracts the pixel coordinates of the laser reflection spot, and then calculates the actual distance between the detection point at the bottom of the corrugated pipe and the optical detection module 8 by combining parameters such as the fixed installation distance and installation angle between the laser emitter and the image sensor. Then, by continuously acquiring distance data from multiple detection points (uniformly distributed along the axial direction of the corrugated pipe with a spacing of no more than 5 mm), it fits the actual bending curve at the bottom of the corrugated pipe, and then compares it with the preset standard bending curve (set according to the design parameters of the corresponding specification corrugated pipe) to calculate the bending deviation value.
[0029] When the calculated curvature deviation exceeds a preset threshold (which is set according to the corrugated pipe specifications and support stability requirements, typically 0.2-0.5mm), it indicates that the support gap in the corresponding detection area is too large. The embedded signal processing unit immediately sends a control signal to the device's main control system, clearly identifying the area with abnormal curvature and the corresponding adjacent electrically controlled strut 7. After receiving the signal, the main control system precisely controls the synchronous extension and retraction of the electrically controlled struts 7 on both sides adjacent to the area: through the extension action of the electrically controlled strut 7, the corresponding flip adjustment arm 61 is pushed to slightly flip around its hinge point with the rigid mounting plate 10, causing the external telescopic rod 62 and the arc-shaped support frame 63 to move closer to the bottom of the corrugated pipe, thereby reducing the support gap between the arc-shaped support frame 63 and the bottom of the corrugated pipe.
[0030] During the process of the electrically controlled strut 7 driving the electrically controlled support arm 6 to rotate and adjust, the optical detection module 8 continuously monitors the area in real time, constantly collecting the bending data of the bottom of the corrugated pipe and feeding it back to the signal processing unit to form a closed-loop control: if the bending deviation value drops to within the preset threshold, it means that the support gap has been adjusted to a reasonable range, the signal processing unit sends a stop signal, the electrically controlled strut 7 stops extending and retracting, and maintains the current support posture; if the deviation value still does not meet the standard, the extension and retraction of the electrically controlled strut 7 will continue to be finely adjusted until the bending meets the standard, thereby realizing real-time detection and dynamic adjustment through optical technology, continuously ensuring the support stability of the stainless steel corrugated pipe, and avoiding the problems of swaying and shaking caused by excessive support gap.
[0031] The working principle and process of this device are as follows: Before operation, adjust the posture of the electrically controlled support arm 6 according to the specifications of the stainless steel corrugated pipe to be tested. By adjusting the extension length of the external telescopic rod 62, make the arc-shaped support frame 63 fit the curved surface of the corrugated pipe. Then, fix the position of the external telescopic rod 62 by adjusting the support rod 65. At the same time, adjust the position of the sliding mounting seat 12, adjust the optical detection module 8 to a suitable detection position, and tighten the side locking bolt 13 to fix it. By extending and retracting the electrically controlled support rod 7, adjust the flip angle of the flip adjustment arm 61 so that the arc-shaped support frame 63 can stably support the corrugated pipe.
[0032] During operation, the stainless steel corrugated pipe to be tested is placed on the arc-shaped support frame 63, and the main drive motor 9 is started. The main drive motor 9 drives the lower drive wheel 52 to rotate, and the lower drive wheel 52 drives the upper drive wheel 42 to rotate synchronously. This drives the electrically controlled upper conveyor belt 4 and the electrically controlled lower conveyor belt 5 to run synchronously and coaxially. The rigid mounting plate 10 moves with the conveyor belt, driving the electrically controlled support arm 6 and the corrugated pipe supported on it to move synchronously. The optical positioning control module 15 monitors the movement position of the electrically controlled support arm 6 and the electrically controlled support rod 7 in real time. When the two move with the conveyor belt to one end of the embedded horizontal guide rail 3, the optical probe of the optical positioning control module 15 captures the position signal, immediately triggers optical positioning, and synchronously transmits the positioning signal to the main control system.
[0033] After receiving the signal, the main control system quickly issues control commands to retract the electrically controlled support rod 7 and flip the electrically controlled bracket 6 to its reset position. This ensures that the arc-shaped support frame 63 of the electrically controlled bracket 6 fits tightly against the outer wall of the stainless steel corrugated pipe. Simultaneously, the system adjusts the posture of adjacent electrically controlled brackets 6 to ensure all brackets are in a reset position against the corrugated pipe, preventing either the electrically controlled bracket 6 or the electrically controlled support rod 7 from protruding into the passage area of the lateral transition opening 11, thus providing sufficient space for the corrugated pipe to pass. Once the electrically controlled bracket 6 and the electrically controlled support rod 7 have completed their reset and fitting, the optical positioning control module 15 sends a confirmation signal. The control system maintains the current posture, ensuring the corrugated pipe passes smoothly through the lateral transition opening 11 during transport, avoiding problems such as jamming or scratching.
[0034] During the movement of the bellows, the optical inspection module 8 simultaneously scans and inspects the inner and outer walls of the bellows, checking for defects such as cracks, dents, uneven wall thickness, and oxide scale. The inspection data is transmitted to the control terminal in real time, allowing staff to monitor the inspection results. When the bellows moves with the electrically controlled support arm 6 to the lateral transition port 11, the electrically controlled support arm 6 and the electrically controlled strut 7 have already been reset and fitted under the control of the optical positioning control module 15. The bellows can then smoothly pass through the lateral transition port 11 and exit the device, completing the inspection process. The entire process achieves continuous connection between bellows transportation and inspection, ensuring both transportation stability and, through the precise control of the optical positioning control module 15, ensuring the smooth passage of the bellows through the lateral transition port 11, thus improving the smoothness of the device's operation.
