[0002] The pile legs of wind turbine installation vessels are key structures that support the hull and operating equipment. The machining accuracy of the pile leg holes directly affects the assembly stability of the pile legs and related components, as well as the safe operation of the entire equipment. In the pile leg hole machining process, boring and milling are the two core processes. Boring is used to ensure the dimensional accuracy, roundness and surface finish of the holes, while milling is used to process the forming of related structures such as the end face of the hole and the step surface. At present, the boring and milling operations of the pile leg holes in the industry are usually completed with split equipment, that is, dedicated boring equipment and milling equipment are used for processing in sequence. The two types of equipment need to be installed and debugged separately according to the processing procedures before being put into use.

[0003] However, the existing ship pile leg hole boring equipment and milling equipment have the following shortcomings when in use: on the one hand, the boring equipment and the milling equipment are independent of each other. During processing, it is necessary to complete the boring operation first, then disassemble the boring equipment, and then install and debug the milling equipment. Not only is there a time loss of multiple alignments and equipment switching, resulting in low processing efficiency; on the other hand, the boring equipment and the milling equipment are installed and debugged based on different benchmarks, and errors are prone to occur during the secondary calibration process, making it difficult to ensure the coaxiality and position accuracy of the boring and milling processes, affecting the overall processing quality of the pile leg holes.

[0004] Therefore, it is necessary to provide an integrated device for boring and milling the pile leg holes of a wind power installation ship to solve the above technical problems. Summary of the Invention

[0016] Compared with related technologies, the integrated device for boring and milling pile leg holes of wind turbine installation vessels provided by the present invention has the following beneficial effects: The device integrates a boring cutter and a milling cutter, each of which is independently driven and adjusted. The boring cutter is powered by motor one, with axial and radial adjustment enabled by motor two and the boring cutter feed mechanism. The milling cutter is driven by motor four, with adjustment facilitated by motor three and an electric push rod. During machining, the boring cutter and milling cutter operate synchronously, while the moving platform simultaneously moves along the arc of the optimal travel frame, expanding the coverage area and reducing the number of adjustments required for the pile legs.

Furthermore, simultaneous machining based on a common datum (the fixed and rotating drums are coaxial), avoids secondary datum calibration errors and effectively improves machining efficiency and accuracy.

[0017] The boring tool feed mechanism is built into the drum, integrating transmission components such as the lifting push rod, spur rack, worm, and worm gear within the drum. This completely avoids the space occupation problem caused by the radial dimensions of traditional external feed structures. The minimum machinable hole diameter is only limited by the drum itself, which allows it to accommodate smaller diameter pile leg holes and expands its scope of application. At the same time, the reverse self-locking characteristics of the worm and worm gear can stably lock the position of the moving slide, resist the reaction of cutting forces, avoid feed deviation, and ensure boring accuracy.

[0018] By arranging components such as an air pump, an exhaust pipe, a convex air box, an upper air pipe, a hose, and a lower air pipe, an air permeable path is formed in the rotating drum. The high-pressure gas generated by the air pump is transported to the jet box through the above-mentioned air path, and is directionally sprayed onto the straight rack two through the jet narrow opening, so as to promptly remove debris on the hanging straight rack two and avoid jamming of the meshing with the gear nine, which is conducive to ensuring smooth transmission and improving the reliability of the operation of the device; the hose can adapt to the lifting and lowering movement of the upper air pipe, and the convex air box is rotatably sealed with the hollow rod, so that the various components of the automatic cleaning can adapt to the lifting and rotation of the lifting push rod in the boring tool feed mechanism during operation, and will not hinder the operation of the boring tool feed mechanism, thereby ensuring the coordinated execution of the cleaning function and the boring process.

A rotating rod 38 rotatably installed in the rotating drum 7 , a worm wheel 39 is fixedly sleeved on the top of the rotating rod 3 38 , the worm 36 is meshed with the worm wheel 39 , and the worm 36 drives the worm wheel 39 and the rotating rod 3 38 to rotate.

The reverse self-locking characteristic of the worm gear transmission can be used to lock the position of the movable slide 41 after the boring tool 13 is fed into place, thereby avoiding the feed deviation caused by the reaction of the cutting force and ensuring the dimensional accuracy of the bored hole. Compared with the solution in which the boring tool feeding component is placed outside the rotating spindle in the traditional design, this type of external structure will increase the minimum machinable diameter of the bored hole due to the superposition of its own radial dimensions (for example, the radius of the boring tool rotating spindle is 50mm, the external feeding mechanism needs to occupy an additional 100mm of radial space, then the minimum machining aperture of the boring tool needs to be ≥Φ300mm). The present invention, through a built-in design, embeds the transmission structure into the rotating drum 7, which not only avoids the interference of external redundant components with the rotary cutting action of the boring tool 13, but also completely eliminates the problem of radial space occupation by the external structure, so that the minimum machinable aperture of the boring tool 13 is only restricted by the structure of the rotating drum 7 itself, greatly expanding the processing adaptability of the device to small-diameter pile leg holes. At the same time, the built-in layout can also use the shell of the rotating drum 7 to protect the internal transmission parts, reducing the erosion of related components caused by cutting debris.

The motor 6 46 drives the screw rod 2 45 to rotate, and drives the lifting strip plate 44 to move up and down along the limit slide 2 43 through the screw nut transmission, thereby driving the lifting push rod 32 to move axially synchronously, providing power input for the boring tool feeding mechanism.

[0031] In this embodiment: When the device is in use, the walking support components at both ends of the optimal arc walking frame 1 roll along the external I-shaped slide rails to achieve overall displacement adjustment; the mobile platform 3 moves along the arc trajectory of the optimal arc walking frame 1 under the drive of the walking mechanism, and the torque output by the motor 5 29 during operation is transmitted to the rotating shaft 27 through the gear 6 30 and the gear 7 31, driving the gears 5 28 at both ends to engage with the arc rack 2, and converting the rotational motion into an arc translation of the mobile platform 3, and cooperating with the rolling guide of the supporting circular roller in the arc-shaped limit slide groove, thereby achieving coverage of different circumferential positions of the pile leg hole, and the two-dimensional translation platform 4 is precisely moved through the X and Y axes to fine-tune the processing positions of the boring cutter 13 and the milling cutter 14 in the horizontal plane to ensure the accuracy of the processing benchmarks of both; During boring, the motor 18 drives the drum 7 to rotate around its own axis through the meshing transmission of the gear 19 and the gear 2 10, driving the boring tool 13 to rotate synchronously, providing cutting power. The motor 2 11 drives the screw 12 to rotate, and drives the lifting platform 6 to rise or fall along the limit slide 1 5 through the screw nut transmission, thereby adjusting the axial feed depth of the boring tool 13. When the motor 6 46 is running, it drives the screw 2 45 to rotate, driving the lifting strip 44 to rise and fall along the limit slide 2 43, thereby pushing the lifting push rod 32 to move axially. The lifting push rod 32 drives the straight rack 1 34 through the curved rod 33. Sliding. Under the limiting action of the C-shaped limiting member, the spur rack 1 34 only slides along the axial straight line, causing the gear 8 37 and the rotating rod 2 35 to rotate, driving the worm 36 to rotate synchronously, and the worm 36 engages with the worm wheel 39 to achieve motion reversal, driving the rotating rod 38 and the gear 9 40 to rotate. Finally, through the engagement of the gear 9 40 and the spur rack 2 42, the movable slide 41 is pushed to move radially, completing the precise feeding of the boring tool 13. The self-locking characteristics of the worm 36 and the worm wheel 39 are used to ensure the stable position of the boring tool 13 after feeding. In addition, the boring tool feeding structure is a built-in design, which greatly reduces the minimum machinable hole diameter range. During the above-mentioned boring process, the milling cutter 14 can perform milling operations synchronously. During milling processing, the milling cutter positioning mechanism realizes multi-position milling through three-dimensional adjustment, and does not interfere with the boring operation of the boring cutter 13. When the motor four 26 is running, it drives the rotating rod one 25 to rotate, driving the milling cutter 14 to rotate at high speed. The motor three 17 drives the gear three 18 to engage with the gear four 19 on the fixed cylinder 15, driving the ring 16 to rotate around the fixed cylinder 15, thereby adjusting the circumferential coverage range of the milling cutter 14. In terms of radial and depth adjustment, the electric push rod two 23 pushes the slide 21 to move radially along the slide rail 20, changing the cutting radius of the milling cutter 14, and the electric push rod one 22 telescopes to drive the polygonal slide column and the fixed seat 24 to rise and fall, adjusting the axial milling depth of the milling cutter 14, and the polygonal slide column passes through the avoidance square opening on the slide rail 20 to avoid motion interference. The coordinated actions of the rotation of the ferrule 16, the movement of the slide 21 and the lifting of the fixed seat 24 can realize the milling of the end face, step surface and stepped hole of the pile leg hole, and the boring tool 13 can continuously perform the boring operation. The high-pressure gas generated by the air pump 47 is transported to the jet box 54 through the exhaust pipe 50, the hollow rod 49, the convex air box 48, the upper air pipe 51, the hose 52 and the lower air pipe 53, and is sprayed onto the spur rack 2 42 through the jet narrow opening at the bottom just above the spur rack 2 42. This can promptly clean the cutting debris attached to the spur rack 2 42, avoid the debris from getting stuck and affecting the transmission accuracy, and ensure the stability of the simultaneous processing process of the boring cutter 13 and the milling cutter 14.
