[0004] For example, a steel pipe pile welding seam self-powered self-adaptive underwater detection device with the publication number CN216747568U belongs to the technical field of measurement.

However, the welds of the residual defects on the surface of part of the steel pipe pile are filled and covered by the welding slag during detection, which causes certain errors in the accuracy of laser penetration during detection, and the detection is limited due to the filled welding slag. SUMMARY

[0008] To achieve the above purpose, the present application provides the following technical scheme:

[0009] The steel pipe pile full-process automatic processing and online detection system comprises a reserved base, a threaded transmission rod is installed on the outer side of the reserved base, an X-ray flaw detection component is butt-jointed on the outer side of the threaded transmission rod, and an external supply pipe is installed on the upper end of the X-ray flaw detection component.

A butt-joint reserved part is installed on the upper end of the reserved base, and the butt-joint reserved part penetrates the inside of the steel pipe pile. A nested contact part is butt-jointed on the inner side of the butt-joint reserved part through a spring nest, and an auxiliary guiding detection component is arranged between the butt-joint reserved part and the reserved base to assist in controlling the detection accuracy of the overall steel pipe pile.

[0010] Further, the auxiliary guiding detection component is provided with a meshing synchronous belt, and the left end of the meshing synchronous belt is meshed and butt-jointed on the outer side of the threaded transmission rod. An eccentric wheel is rotatably butt-jointed on the outer side of the butt-joint reserved part, and the shaft end outer side of the eccentric wheel is meshingly butt-jointed with the right side of the meshing synchronous belt. An external butt-joint part is nested and installed on the lower end outer side of the reserved base, and the outer side of the external butt-joint part corresponds to the outer side of the eccentric wheel. An internal steel wire rope is butt-jointed on the outer side of the external butt-joint part, and the internal steel wire rope penetrates along the inner side of the reserved base. The end of the internal steel wire rope is butt-jointed with the lower end of the nested contact part.

[0011] Further, the upper end outer side of the butt-joint reserved part is fixedly connected with a magnetic attraction butt-joint part, and the upper end inner side of the butt-joint reserved part is rotatably connected with a movable reserved magnetic attraction piece.

[0012] Furthermore, the X-ray flaw detection component moves laterally along the outside of the reserved base via a threaded drive rod, and the threaded drive rod forms a rotating structure with the eccentric wheel through a meshing synchronous belt, and the outer side of the eccentric wheel applies pressure to the external docking component when it comes into contact with it.

[0013] Furthermore, the external docking component forms a traction structure with the lower end of the nested abutment component through the built-in steel wire rope, and the outer side of the upper end of the nested abutment component is an arc-shaped rubber component structure; the movable reserved magnetic absorbing piece rotates along the upper end of the docking reserved component until it is attracted to the magnetic docking component during the contact with the wind force, and the outer side of the docking reserved component is provided with a scale.

[0014] Furthermore, a guiding docking component for quickly removing floating dust from the workpiece surface is provided between the interior of the reserved base and the nested abutment component; the guiding docking component is provided with an external fixing component, and the external fixing component is fixedly docked to the lower end of the nested abutment component; an air storage reserved cavity is opened on the inner side of the lower end of the reserved base, and a fitting piston component is nested and installed inside the air storage reserved cavity, and the upper end of the fitting piston component corresponds to the lower end of the external fixing component.

[0015] Furthermore, a return spring is fixedly connected to the lower end of the fitting piston component, and the return spring is connected to the inner side of the gas storage reserved cavity. A docking reserved tube is provided at the lower end of the reserved base, and the lower end of the docking reserved tube is connected to the lower end of the gas storage reserved cavity. A reserved through hole is opened on the inner side of the upper end of the gas storage reserved cavity, and the reserved through hole passes through the inner side of the reserved base.

[0016] Furthermore, during the downward movement of the nested contact member, the external fixing member moves vertically in sync, and the external fixing member applies pressure to the contacting piston member in sync, and the contacting piston member moves along the inner side of the air storage cavity through the return spring.

[0017] Furthermore, after the fitting piston moves to the lower end of the reserved through hole, airflow is supplied to the outside through the closed air storage reserved cavity via the docking reserved pipe.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] This fully automated processing and online inspection system for steel pipe piles is equipped with auxiliary guidance inspection components. These components assist in controlling the overall inspection accuracy of the steel pipe piles. An external supply pipe, in conjunction with an external air pump, adaptively sprays air along the outer side of the workpiece. If residual weld slag remains at the weld seam on the surface of the workpiece, it will be removed using the pre-reserved docking pipe at the bottom of the equipment. Simultaneously, the residual weld seam will pass through the airflow, causing the movable pre-reserved magnetic chuck at the corresponding docking pre-reserved part to move under force, thus engaging with the magnetic docking part. Combined with subsequent scale positioning and X-ray flaw detection results, the area of ​​residual weld seam can be accurately identified. This prevents the weld seam on the surface of the steel pipe pile from being filled and covered by weld slag during the inspection process, which would lead to errors in the accuracy of laser penetration during the inspection. The system adaptively removes the filled weld slag, ensuring inspection accuracy while achieving stable adaptive positioning of the workpiece. This improves the overall processing accuracy of the automated equipment and extends the corrosion protection life of subsequent processing.

[0020] Furthermore, during the operation of the threaded transmission rod, it will drive the eccentric wheel to rotate in a circular motion through the meshing synchronous belt. This, in turn, will apply pressure to the contacting external mating parts in sync with the eccentric wheel. The external mating parts will then drive the nested abutment parts to move down synchronously through the built-in steel wire rope. The nested abutment parts will then self-position the lower inner side of the contacting pipe through the upper arc-shaped rubber part. This will prevent the problem of positional correction or inability to rotate and transmit during the movement of the transmission roller components, thereby improving the detection stability of the device.

[0021] Furthermore, a guiding docking component is provided to quickly remove floating dust from the workpiece surface. During the process of the overall nested contact component being positioned by force, the outer fixing component docking with it will move vertically along the inner side of the air storage cavity, allowing the outer fixing component to apply pressure to the contacting piston component. As the contacting piston component moves inward, after it moves to the lower end of the reserved through hole, airflow is supplied outward through the closed air storage cavity via the docking reserved pipe to remove dust from the surface of the contacting workpiece, assisting in the removal of weld impurities and ensuring the accuracy of subsequent inspections.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figures 1-9This invention provides the following technical solution: a fully automated processing and online inspection system for steel pipe piles. To address the technical problem that during the inspection process, some residual defects on the surface of steel pipe piles are filled and covered by weld slag, leading to errors in the accuracy of laser penetration and limitations in inspection due to the filling weld slag, the invention discloses a system including a reserved base 1, a threaded transmission rod 2 installed on the outer side of the reserved base 1, and an X-ray flaw detection component 3 connected to the outer side of the threaded transmission rod 2. Furthermore, an external supply pipe 4 is installed at the upper end of the X-ray flaw detection component 3, and a transmission roller component 5 is installed at the upper end of the reserved base 1 via a motor. The outer side of the transmission roller component 5 supports the steel pipe pile to be inspected. A docking reserved part 8 is installed at the upper end of the reserved base 1, and the docking reserved part 8 penetrates the interior of the steel pipe pile. The inner side of the docking reserved part 8 is connected to a nested abutment part 11 via a spring nesting. An auxiliary guiding detection component is set between the docking reserved part 8 and the reserved base 1 to assist in controlling the detection accuracy of the overall steel pipe pile.

[0034] The auxiliary guiding detection component is equipped with a meshing synchronous belt 6, and the left end of the meshing synchronous belt 6 is meshed with the outside of the threaded transmission rod 2. The outer side of the docking reserved part 8 is rotatably docked with an eccentric wheel 7, and the outer side of the shaft end of the eccentric wheel 7 is meshed with the right side of the meshing synchronous belt 6. An external docking part 18 is nested on the outer side of the lower end of the reserved base 1, and the outer side of the external docking part 18 corresponds to the outer side of the eccentric wheel 7. An internal steel wire rope 19 is docked to the outer side of the external docking part 18, and the internal steel wire rope 19 runs along the inner side of the reserved base 1. The end of rope 19 is connected to the lower end of nested contact member 11. A magnetic contact member 9 is fixedly connected to the outer side of the upper end of the docking reserved member 8, and a movable reserved magnetic suction piece 10 is rotatably connected to the inner side of the upper end of the docking reserved member 8. The X-ray flaw detection component 3 moves laterally along the outer side of the reserved base 1 via the threaded transmission rod 2, and the threaded transmission rod 2 forms a rotating structure with the eccentric wheel 7 through the meshing synchronous belt 6. When the outer side of the eccentric wheel 7 contacts the external docking member 18, it applies pressure to it. The external docking member 18 forms a connection with the lower end of nested contact member 11 via the built-in steel wire rope 19. The traction structure, and the upper outer side of the nested contacting part 11 is an arc-shaped rubber structure. During the contact of the movable reserved magnetic suction plate 10 with the wind, it rotates along the upper end of the docking reserved part 8 until it is attracted to the magnetic docking part 9. The outer side of the docking reserved part 8 is set with a scale. During the forming and preparation of steel pipe piles, the steel coil is hoisted to the flattening machine by an intelligent crane, and the steel plate is scanned by a laser flatness detector. The qualified steel plate is sent to the milling machine to process the bevel. Subsequently, the steel plate is rolled into a cylindrical shape by a CNC rolling machine, and the circumferential submerged arc welding is performed by a welding robot. X-ray is turned on simultaneously. The flaw detection component 3 detects weld defects. After inspection and repair, the short steel pipe is transported to the extension station via a support roller. A crawling vision robot positions the pipe inside, and a welding robot completes the extension circumferential welding. Then, it enters the sandblasting and rust removal machine. The automatic spraying equipment operates according to the "primer-intermediate paint-topcoat" process. Each steel pipe pile is laser-engraved with a unique code, including specifications and batch number. An AMR unmanned forklift moves it to the storage area. The system links the inspection report. The overall automated equipment realizes continuous operation of flattening, welding, and corrosion protection. Online inspection ensures the quality of each process, improves processing accuracy, and extends the corrosion protection life.

[0035] The workpiece to be inspected is placed on the surface of the threaded drive rod 2 after passing through the upper outer side of the docking pre-reserved part 8. In conjunction with the signal reception status between the X-ray flaw detection component 3 and the docking pre-reserved part 8, flaw detection is performed on the surface of the workpiece. Simultaneously, the external supply pipe 4, in conjunction with the external air pump, adaptively ejects airflow along the outer side of the workpiece. If weld slag remains at the weld seam on the contacted workpiece surface, it will be removed using the docking pre-reserved pipe 17 at the lower end of the equipment. The remaining weld seam will be penetrated by the airflow, causing the movable pre-reserved magnetic suction piece 10 at the corresponding docking pre-reserved part 8 to move under force, thus engaging with the magnetic docking part 9. Combined with subsequent scale positioning and the detection results of the X-ray flaw detection component 3, accurate results are obtained. To identify areas with residual welds and prevent the weld slag from filling and covering some of the steel pipe pile surface defects during inspection, thus avoiding errors in the accuracy of laser penetration during inspection, the residual weld slag is automatically removed. This ensures the accuracy of inspection while achieving stable self-positioning of the workpiece. During the operation of the threaded transmission rod 2, it drives the eccentric wheel 7 to rotate circumferentially through the meshing synchronous belt 6. The eccentric wheel 7 then applies pressure to the contacting external docking part 18, causing the external docking part 18 to move down synchronously through the built-in steel wire rope 19. The nested abutment part 11 then self-positions itself against the lower inner side of the contacting pipe through the upper arc-shaped rubber part.

[0036] Example 2: Based on Example 1, to address the limitation of detection accuracy caused by residual welding slag and other impurities on the workpiece surface, a guiding docking component is also disclosed, the specific structure of which is as follows:

[0037] A guide docking component for quickly removing floating dust from the workpiece surface is provided between the interior of the reserved base 1 and the nested abutment 11;

[0038] The guiding docking component is equipped with an external fixing member 12, which is fixedly docked to the lower end of the nested abutment member 11. An air storage cavity 13 is provided on the inner side of the lower end of the reserved base 1, and a fitting piston member 15 is nested inside the air storage cavity 13. The upper end of the fitting piston member 15 corresponds to the lower end of the external fixing member 12. A return spring 14 is fixedly connected to the lower end of the fitting piston member 15, and the return spring 14 is docked with the inner side of the air storage cavity 13. A docking reserved tube 17 is provided at the lower end of the reserved base 1, and the lower end of the docking reserved tube 17 is connected to the lower end of the air storage cavity 13. A reserved through hole 16 is provided on the inner side of the upper end of the air storage cavity 13, and the reserved through hole 16 penetrates along the inner side of the reserved base 1. During the downward movement of the nested abutment member 11, the external fixing member 12 moves vertically synchronously. 2. The contacting piston parts 15 are simultaneously pressurized, and the contacting piston parts 15 move along the inner side of the air storage cavity 13 through the return spring 14. After the contacting piston parts 15 move to the lower end of the reserved through hole 16, airflow is supplied to the outside through the closed air storage cavity 13 by the docking reserved pipe 17. During the process of the nested abutting part 11 being forcefully moved to position the workpiece, the outer fixing part 12 docked on its outer side will move vertically along the inner side of the air storage cavity 13, so that the outer fixing part 12 presses the contacting piston parts 15. As the contacting piston parts 15 move inward, after the contacting piston parts 15 move to the lower end of the reserved through hole 16, airflow is supplied to the outside through the closed air storage cavity 13 by the docking reserved pipe 17 to remove dust from the surface of the contacting workpiece and assist in the removal of weld impurities.
