Technical Field

[0001] This invention relates to the field of steel pipe pile spraying technology, specifically to an adaptive rotation mechanism for external spraying of steel pipe piles. Background Technology

[0002] Steel pipe piles are commonly used in major infrastructure projects such as buildings, bridges, and marine engineering. During long-term use, especially in marine or harsh environments, they are susceptible to corrosion from water, salt spray, and acids and alkalis. Applying a coating to their outer surface can effectively prevent corrosion, reduce oxidation, and enhance their resistance to environmental stresses. Furthermore, the coating improves the wear resistance and impact resistance of the steel pipe piles, thereby enhancing the structural safety and stability and reducing subsequent maintenance costs.

[0003] The offshore wind power industry is increasingly demanding ultra-large diameter steel pipe piles, leading to higher requirements for their corrosion protection and coating. However, traditional coating operations are usually carried out manually, which cannot accurately adapt to complex steel pipe piles of different diameters. It is also difficult to ensure the uniformity of the coating during the operation, resulting in poor coating quality and low efficiency. Summary of the Invention

[0017] 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.

[0018] Please see Figure 1-10 The present invention provides a technical solution: An adaptive rotation mechanism for external spraying of steel pipe piles, as shown in the attached instruction manual. Figure 1 As shown, it includes: Chassis 1, with a flexible track 2 on chassis 1, the flexible track 2 being made of rubber and capable of bending; The moving device includes an axial moving component, a vertical moving component, and a horizontal moving component. The axial moving component is used to drive the housing 1 to move along the axial direction of the steel pipe pile. The vertical moving component and the horizontal moving component are both installed in the housing 1. The vertical moving component is used to drive the flexible track 2 to move in the vertical direction, and the horizontal moving component is used to drive the flexible track 2 to move in the horizontal direction.

[0019] The detection device is used to monitor the surface morphology of steel pipe piles in real time.

[0020] The track adjustment device is used to adjust the curvature of the flexible track 2.

[0021] The spray gun adjustment device includes a spray gun mounting base 3 and a magnetic moving component. The magnetic moving component is used to drive the spray gun mounting base 3 to move along the flexible track 2.

[0022] The liquid connection device is used to quickly connect the spray gun mounting base 3 to the external liquid supply pipeline.

[0023] The axial movement assembly includes a moving track 4 and a moving trolley 5. The moving track 4 is set along the axial direction of the steel pipe pile and is used to limit the movement direction of the moving trolley 5 so that it always moves along the axial direction of the steel pipe pile. The moving trolley 5 is connected to the moving track 4, and the housing 1 is set on the moving trolley 5. The moving trolley 5 is used to drive the housing 1 to move.

[0024] The vertical moving component includes a lifting platform 6, which is a hydraulically driven lifting platform. The specific model can be reasonably purchased according to the size of the moving trolley 5. The lifting platform 6 is set on the top of the chassis 1, and the horizontal moving component is set on the lifting platform 6.

[0025] The horizontal moving assembly includes a limiting plate 7, a moving push rod 8, and a moving block 9. The limiting plate 7 is set on the lifting platform 6, and the limiting rod is provided with a limiting groove. The limiting groove is used to restrict the movement direction of the moving block 9, so that the moving block 9 can only move along the direction of the limiting groove. The moving push rod 8 is set on the limiting plate 7, and the moving block 9 is connected to the limiting groove. The moving push rod 8 is used to drive the moving block 9 to move along the limiting groove.

[0026] The detection device includes a laser rangefinder 10, which is mounted in the housing 1. The laser rangefinder 10 is used to monitor the surface morphology of the steel pipe pile in real time. It emits a laser beam and receives the reflected laser light, calculating the round-trip time of the laser beam to obtain distance information to the surface of the steel pipe pile, thus achieving real-time monitoring of the surface morphology. When the surface of the steel pipe pile is uneven (e.g., a reducing flange is present on the movement path), the laser rangefinder 10 can accurately detect these changes and feed the data back to the control system. The control system then controls the track adjustment device to make corresponding adjustments.

[0027] The track adjustment device includes a rotating motor 11, a rotating seat 12, an adjusting push rod 13, an adjusting plate 14, and a connecting seat 15. The rotating seat 12 is connected to the moving block 9 and is used to install the adjusting plate 14. The rotating motor 11 is used to drive the rotating seat 12 to rotate. The adjusting plate 14 and the rotating seat 12 are hinged to each other. The two ends of the adjusting push rod 13 are rotatably connected to the connecting seat 15 and the rotating seat 12, respectively. The connecting seat 15 is symmetrically arranged on both sides of the adjusting plate 14. Therefore, there are two adjusting push rods 13. In this embodiment, the adjusting push rod 13 is a pneumatic push rod.

[0028] The magnetic moving assembly includes a steel bar 16, a telescopic rod 17, a clamping spring 18, a telescopic rod 19, a clamping spring 20, a drive motor 21, and a magnetic wheel 22. The flexible track 2 has mounting slots on both sides. These slots are used to mount the steel bar 16 and also to restrict the movement direction of the magnetic wheel 22. The steel bar 16 is positioned in the mounting slot. The spray gun mounting base 3 has two telescopic rods 17 on both sides. The clamping spring 18 is located inside the telescopic rod 17, and the telescopic rod 29 is located on one side of the telescopic rod 17. The clamping spring 20 is located inside the telescopic rod 29. The drive motor 21 is located inside the telescopic rod 29 and is a bidirectional servo motor. The drive motor 21 drives the magnetic wheel 22 to rotate. The magnetic wheel 22 is connected to the mounting slot, and the magnetic wheel 22 and the steel bar 16 are attracted to each other. The clamping springs 18 and 20 ensure that the magnetic wheel 22 remains in contact with the steel bar 16.

[0029] The telescopic rod 19 includes an outer rod 1901 and an inner rod 1902. Both the outer rod 1901 and the inner rod 1902 are columnar structures, so they can rotate relative to each other. This prevents the magnetic pulley 22 from getting stuck after the flexible track 2 changes shape. The outer rod 1901 and the inner rod 1902 are hollow inside. The two ends of the clamping spring 20 are connected to the inner wall of the outer rod 1901 and the inner wall of the inner rod 1902, respectively.

[0030] The liquid circuit docking device includes a quick connector 24, a docking opening valve one 25, and a docking opening valve two 26. The quick connector 24 is used to install the spray gun. The quick connector 24 and the docking opening valve one 25 are both located on the spray gun mounting base 3. The quick connector 24 is connected to the docking opening valve one 25 through a pipe. The docking opening valve two 26 are evenly spaced on the flexible track 2. The docking opening valve one 25 and the docking opening valve two 26 are existing technologies, and can be reasonably selected according to the actual situation during use.

[0031] Working principle: During use, the outer surface of the steel pipe pile is inspected by the laser rangefinder 10. Based on the inspection results, the height of the spray gun is adjusted by the lifting platform 6. The moving push rod 8 drives the moving block 9 to move along the limiting groove, thereby adjusting the horizontal position of the spray gun. The rotating motor 11 drives the rotating seat 12 to rotate, thereby adjusting the spray angle of the spray gun. By controlling the extension and retraction of the adjusting push rod 13, the direction of the flexible track 2 is the same as the circumference of the steel pipe pile. Then, the moving trolley 5 drives the machine box 1 to move along the radial direction of the steel pipe pile. During the movement, the spray gun sprays the steel pipe pile. After spraying, the drive motor 21 drives the magnetic suction wheel 22 to rotate, thereby driving the spray gun mounting seat 3 to move along the flexible track 2. At this time, the spray gun will rotate along the circumference of the steel pipe pile, and the distance between the axis of the spray gun and the steel pipe pile remains unchanged, thus maintaining the same spraying distance. Then, the moving trolley 5 moves in the opposite direction to spray other positions.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
