Description

Technical Field

[0001] The present invention relates to the technical field of flange production, and specifically to a drilling device and method for offshore wind power flange production. Background Technique

[0002] Drilling of offshore wind power flanges is a crucial step in the production process. The main purpose is to ensure the precise docking of flange connection components, thereby guaranteeing the connection stability between the flange and other components such as tower barrels and blades. The drilling process requires high-precision drilling devices to complete. These devices usually include numerical control drilling machines, hydraulic drilling machines, etc., which can adjust the drill bit type and drilling depth according to different requirements. The structure of the drilling device generally consists of a drive system, a drill bit system, a positioning system, and a control system. The drive system provides sufficient power to ensure that the drill bit penetrates the flange material smoothly. The drill bit system selects an appropriate drill bit according to the material to ensure the smooth progress of drilling. The positioning system ensures the accuracy of drilling. Common positioning methods include mechanical positioning and laser positioning. The control system is used to precisely control various parameters during the drilling process, improving the automation level and accuracy.

[0003] For example, an automated drilling device for wind power flange production disclosed in the authorized announcement number CN118989398B includes a tooling table; a fixed bracket; a dust-proof multi-element drilling unit, which is arranged between the fixed bracket and the tooling table and is connected to the fixed bracket; a positioning and supporting unit, which is connected to the tooling table; a gas guiding and dust collecting unit, which is connected to the tooling table and is also connected to the dust-proof multi-element drilling unit. Among them, the dust-proof multi-element drilling unit includes: a multi-unit synchronous perforation component, a spacing regulation component, and an isolation and protection component. By setting the dust-proof multi-element drilling unit, the drilling of the wind power flange can be completed at one time, and the blocking and recovery of debris can be completed during drilling. The existing drilling technologies and device operation methods for offshore wind power flanges are basically the same, that is, the flange needs to be fixed on the drilling equipment to ensure accurate and unbiased position. Then, the drill bit starts and begins to drill under the guidance of the control system. Finally, after the drilling is completed, the equipment will automatically retract and perform quality inspection. However, when using multiple dust-proof multi-element drilling units for multi-point synchronous hole opening in the above technical solution, each drilling unit requires a drive motor for driving, and each spacing regulation component also requires a motor for driving. Although the above design ensures the independence and high precision of the drilling process for each hole position, it inevitably leads to a huge consumption of motor equipment in the device. That is to say, as the number of motors increases, the structure of the entire drilling device will become more complex, and more motors, control systems, and drive devices need to work in coordination, which undoubtedly increases the complexity of the device. Moreover, each independently driven drilling unit and spacing regulation component requires a motor to provide power, which also means that the device consumes relatively high energy during operation. Summary of the Invention

[0004] The purpose of the present invention is to provide a drilling device and method for the production of offshore wind power flange. A multi-bit rotary drive unit drives multiple pulley-type position adjustment assemblies to work together, so that each pulley-type position adjustment assembly drives an opening assembly to move, enabling multiple opening assemblies to synchronously adjust the distance, thereby changing the working positions of the opening assemblies according to the processing requirements of the offshore wind power flange. After the working positions are adjusted, the pulley drive assembly, the main shaft, the bevel gear multi-directional transmission assembly, and the keyway-type telescopic drive shaft drive the opening assembly to work.

[0012] Preferably, the double-column truss includes two symmetrical steel columns fixed on one outer wall of the lower cross hanging plate, U-shaped end seats fixed at the same end of the two steel columns, and a double-sleeve sliding table slidably mounted on one end of the steel column surface.

[0016] The present invention also provides a drilling method for the production of offshore wind power flanges. For the drilling device for the production of offshore wind power flanges as described above, it includes the following steps:

[0017] S101: First, ensure that all components are correctly installed, and check the operating status of the multi-position rotary drive unit, pulley-type position adjustment assembly, bevel gear multi-directional transmission assembly, keyway-type telescopic transmission shaft, and screw rod lifting module to ensure that each component operates normally under no-load conditions. Finally, check whether the rotation and traction range of the pulley-type position adjustment assembly meet the design requirements to ensure that there is no jamming in each transmission component;

[0018] S102: Drive each pulley-type position adjustment assembly to work through the multi-position rotary drive unit. By using the coordinated work of the multi-position rotary drive unit and the pulley-type position adjustment assembly, the staff controls the opening positions of the opening assemblies according to the size and processing requirements of the offshore wind power flange workpiece until each opening assembly reaches the predetermined operation requirements driven by the pulley-type position adjustment assembly;

[0019] S103: After adjusting the positions of the opening assemblies, the staff starts the pulley drive assembly to work. The pulley drive assembly drives the main shaft to rotate, and the rotation power of the main shaft is transmitted to each keyway-type telescopic transmission shaft through the bevel gear multi-directional transmission assembly. Then, the bevel gear multi-directional transmission assembly and the keyway-type telescopic transmission shaft evenly distribute the power to each opening assembly to ensure that multiple opening assemblies perform drilling operations synchronously;

[0020] S104: When multiple opening assemblies have been debugged and obtained driving power, the staff starts the drilling operation. By operating the screw rod lifting module, the rear bracket, front bracket, upper suspension plate, lower cross suspension plate, double-column truss, and multiple opening assemblies are synchronously lowered to reach the accurate working height. During the operation process, the staff should adjust the drilling speed and depth parameters of the opening assemblies according to the processing requirements and supervise the drilling progress of each opening assembly.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: The drilling device and method for the production of offshore wind power flanges are provided with a pulley-type position adjustment assembly, a multi-position rotary drive unit, a keyway-type telescopic transmission shaft, a bevel gear multi-directional transmission assembly and other cooperating structures. The multi-position rotary drive unit drives multiple pulley-type position adjustment assemblies to work together, so that each pulley-type position adjustment assembly drives an opening assembly to move, and then multiple opening assemblies synchronously adjust the distance to change the working positions of the opening assemblies according to the processing requirements of the offshore wind power flanges. During the movement of the opening assemblies, the opening assemblies are always power-connected to the bevel gear multi-directional transmission assembly and the main shaft through the keyway-type telescopic transmission shaft. After the working positions are adjusted, the pulley drive assembly, the main shaft, the bevel gear multi-directional transmission assembly and the keyway-type telescopic transmission shaft drive the opening assemblies to work, and then the screw rod lifting module makes multiple opening assemblies move down together and complete multi-point drilling; among them, through the synergistic effect of the multi-position rotary drive unit and the pulley-type position adjustment assembly, the synchronous distance adjustment of multiple opening assemblies is realized. Each pulley-type position adjustment assembly independently drives an opening assembly and can accurately adjust the working position of each opening assembly during the processing. This combination of independent adjustment and synchronous adjustment greatly improves the processing accuracy of large workpieces such as offshore wind power flanges. Moreover, the advantage of this synchronous operation not only improves production efficiency but also effectively reduces the processing errors caused by inaccurate adjustment, thus greatly improving the quality of the finished product; secondly, through the combined application of the keyway-type telescopic transmission shaft and the bevel gear multi-directional transmission assembly, the rotary power can be stably distributed to each opening assembly, ensuring that each assembly can obtain continuous and strong power support regardless of the working angle, avoiding the excessive energy consumption and power waste caused by the simultaneous operation of multiple motors, effectively reducing the redundant work of the motors, improving the overall energy efficiency ratio of the device, and thus reducing the energy cost during long-term operation.

[0022] Through the linkage and cooperation of transmission components such as the bevel gear multi-directional transmission assembly, the keyway-type telescopic transmission shaft and the main shaft, the power of the pulley drive assembly can be evenly transmitted to multiple opening assemblies, ensuring that each opening assembly can complete the work tasks synchronously and stably. This efficient transmission system makes the power transmission more accurate, reduces energy loss, and thus improves the overall operating efficiency of the device. During multi-point operation, it can ensure the precise adjustment and synchronous movement of each working point without increasing the motor load, avoiding the unstable operation phenomenon caused by motor overload.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1, consisting of Figures 1 to 4Given that, the present invention includes a loop-shaped frame 1. At one end inside the loop-shaped frame 1, a rear bracket 2 is slidably installed. On the outer wall of the rear bracket 2 away from the loop-shaped frame 1, a front bracket 3 is fixed. And inside the front bracket 3, a lower cross-shaped suspension plate 8 and an upper suspension plate 5 are respectively fixed from bottom to top. Inside the loop-shaped frame 1, a screw rod lifting module 7 is provided for controlling the Z-axis height of the rear bracket 2. On the outer wall of the lower cross-shaped suspension plate 8, a number of double-column trusses 9 are annularly and equally spaced. At the bottom end of the double-column truss 9, an opening assembly 12 for opening holes in the offshore wind power flange workpiece is slidably installed. The screw rod lifting module 7 can synchronously lower a plurality of opening assemblies 12. Through precise adjustment, it is ensured that the height parameters of a plurality of opening assemblies 12 can all change within an accurate range, thereby ensuring the stability of the hole-opening process and the processing quality.

[0034] Inside the double-column truss 9, a pulley-type position adjustment assembly 14 is provided for driving the opening assembly 12 to approach or move away from the center point of the lower cross-shaped suspension plate 8. At the bottom end of the lower cross-shaped suspension plate 8, a multi-position rotary drive unit 13 is provided for driving a plurality of pulley-type position adjustment assemblies 14 to work together.

[0035] A main shaft 4 is rotatably installed on one side of the top end of the front bracket 3. At the top end of the double-column truss 9, a keyway-type telescopic transmission shaft 10 is provided for maintaining power connection with the opening assembly 12. The bottom end of the main shaft 4 penetrates outside the upper suspension plate 5 and is equipped with a bevel gear multi-directional transmission assembly 11 for driving a plurality of keyway-type telescopic transmission shafts 10 to rotate together. At the top end of the rear bracket 2, a pulley drive assembly 6 is provided for driving the main shaft 4 to rotate.

[0036] Workers can set a tooling for clamping and fixing the offshore wind power flange below the lower cross-shaped suspension plate 8 so that the offshore wind power flange remains stable during the processing. Workers can also install a PLC control panel on the outer wall of one side of the loop-shaped frame 1, so that the motors in the multi-position rotary drive unit 13, the pulley drive assembly 6, and the screw rod lifting module 7 can be electrically connected to the output end of the PLC control panel, thereby controlling the operation of each motor part through the PLC control panel.

[0037] A drilling method for producing an offshore wind power flange in this embodiment, such as the above-mentioned drilling device for producing an offshore wind power flange, includes the following steps:

[0038] S101: First, ensure that all components are correctly installed, and check the operating status of the multi-position rotary drive unit 13, the pulley-type position adjustment assembly 14, the bevel gear multi-directional transmission assembly 11, the keyway-type telescopic transmission shaft 10, and the screw rod lifting module 7 to ensure that each component operates normally under no-load conditions. Finally, check whether the rotation and traction range of the pulley-type position adjustment assembly 14 meet the design requirements to ensure that there is no jamming phenomenon in each transmission component.

[0039] S102: Drive each pulley - type position - adjusting assembly 14 to work through the multi - position rotary drive unit 13. By the coordinated work of the multi - position rotary drive unit 13 and the pulley - type position - adjusting assembly 14, the staff controls the drilling points of the drilling assembly 12 according to the size and processing requirements of the offshore wind power flange workpiece until each drilling assembly 12 reaches the predetermined operation requirements driven by the pulley - type position - adjusting assembly 14;

[0040] S103: After adjusting the position of the drilling assembly 12, the staff starts the pulley drive assembly 6 to work. The pulley drive assembly 6 drives the main shaft 4 to rotate. Then the rotational power of the main shaft 4 is transmitted to each key - groove type telescopic transmission shaft 10 through the bevel gear multi - directional transmission assembly 11. Subsequently, the bevel gear multi - directional transmission assembly 11 and the key - groove type telescopic transmission shaft 10 evenly distribute the power to each drilling assembly 12 to ensure that multiple drilling assemblies 12 perform drilling operations synchronously;

[0041] S104: When multiple drilling assemblies 12 have been debugged and obtained driving power, the staff starts the drilling operation. By operating the lead - screw lifting module 7, the rear bracket 2, the front bracket 3, the upper suspension plate 5, the lower cross - suspension plate 8, the double - column type truss 9, and multiple drilling assemblies 12 are synchronously lowered to reach the accurate working height. During the operation process, the staff should adjust the drilling speed and depth parameters of the drilling assembly 12 according to the processing requirements and supervise the drilling progress of each drilling assembly 12.

[0042] Embodiment 2, based on Embodiment 1, is given by Figure 4 and Figure 5 The pulley drive assembly 6 includes a secondary shaft 602 rotatably installed on one side of the top of the front bracket 3 and a servo - motor 601 installed on one side of the top of the rear bracket 2. The output end of the servo - motor 601 is equipped with a pulley drive structure two 604 for driving the secondary shaft 602 to rotate. The top of the secondary shaft 602 is equipped with a pulley drive structure one 603 for driving the main shaft 4 to rotate. When using the pulley drive assembly 6, the main shaft 4, and the bevel gear multi - directional transmission assembly 11 to drive each drilling assembly 12 to work, the staff starts the servo - motor 601 in the pulley drive assembly 6 to work. The servo - motor 601, the pulley drive structure two 604, the secondary shaft 602, and the pulley drive structure one 603 drive the main shaft 4 to rotate, and the power of the servo - motor 601 is effectively transmitted to the main shaft 4 during this process;

[0043] The keyway type telescopic transmission shaft 10 includes a second bearing seat 1003 slidably mounted on the top end of the double-column type truss 9, an outer key shaft 1004 rotatably mounted inside the second bearing seat 1003, and a first bearing seat 1001 fixed at one side edge position of the top end of the lower cross hanging plate 8. A hollow rotating shaft 1002 is rotatably mounted inside the first bearing seat 1001. One end of the outer key shaft 1004 away from the second bearing seat 1003 extends into the hollow rotating shaft 1002 and is slidably engaged with the hollow rotating shaft 1002. The bottom end of the main shaft 4 drives a plurality of hollow rotating shafts 1002 to rotate through a bevel gear multi-directional transmission assembly 11;

[0044] Two symmetrical straight notches are provided on the outer wall of the hollow rotating shaft 1002, and a convex key slidably engaged with the straight notch is provided on the outer wall of the outer key shaft 1004. The top end of the convex key penetrates to the outside of the straight notch. The bevel gear multi-directional transmission assembly 11 includes a driving bevel gear 1101 fixed at the bottom end of the main shaft 4 and a driven bevel gear 1102 installed at one end of the hollow rotating shaft 1002 close to the center point of the lower cross hanging plate 8. The driving bevel gear 1101 and the driven bevel gear 1102 are meshed with each other;

[0045] The double-column type truss 9 includes two symmetrical steel columns 901 fixed on the outer wall of one side of the lower cross hanging plate 8, U-shaped end seats 902 fixed at the same end of the two steel columns 901, and a double sleeve slide 903 slidably mounted on one end of the surface of the steel column 901. The top end of the double sleeve slide 903 is fixedly connected to the bottom end of the second bearing seat 1003, and the bottom end of the double sleeve slide 903 is fixedly connected to the top end of the opening assembly 12. A convex part connected to the bottom end of the upper hanging plate 5 is installed at the edge position of the top end of the lower cross hanging plate 8;

[0046] The main shaft 4 drives the driving bevel gear 1101 to rotate. Since one end of the hollow rotating shaft 1002 is meshed with the driving bevel gear 1101 through the driven bevel gear 1102, the main shaft 4 drives the hollow rotating shaft 1002 and the outer key shaft 1004 to rotate in sequence by using the driving bevel gear 1101 and the driven bevel gear 1102. At this time, the outer key shaft 1004 can drive the opening assembly 12 to work. Through the cooperation of the bevel gear multi-directional transmission assembly 11, the keyway type telescopic transmission shaft 10 and the multi-directional driving mode, the power of the servo motor 601 can be effectively transmitted to a plurality of opening assemblies 12, which reduces the loss in the power transmission process, enables each opening assembly 12 to obtain sufficient power, and ensures the stability and efficiency of the drilling work; and the structure setting of the multi-directional transmission ensures the synchronism of a plurality of opening assemblies 12, avoids excessive adjustment times caused by non-synchronization or uneven power of a plurality of motors, and improves the continuity and stability of production.

[0047] Example three, on the basis of example two, by Figure 6 、 Figure 7 and Figure 8As shown, the opening assembly 12 includes a right-angle shaft seat 1201 fixed to the bottom end of the double-sliding table 903 and a milling cutter 1202 rotatably installed inside the right-angle shaft seat 1201. The top end of the milling cutter 1202 passes through between the two steel columns 901 and is equipped with a bevel gear 1203 for maintaining power connection with one end of the external key shaft 1004. Another bevel gear is installed on the external key shaft 1004 away from the hollow rotating shaft 1002. The pulley-type position adjustment assembly 14 is used to drive the double-sliding table 903, the second bearing seat 1003, the external key shaft 1004, the right-angle shaft seat 1201, the milling cutter 1202, and the bevel gear 1203 away from or close to the center point of the lower cross-shaped suspension plate 8;

[0048] After the operation point position of the opening assembly 12 is adjusted, during the rotation of the external key shaft 1004 and the hollow rotating shaft 1002, the milling cutter 1202 in the right-angle shaft seat 1201 is driven to rotate by the bevel gear 1203;

[0049] The pulley-type position adjustment assembly 14 includes a driving pulley rotatably installed on one side of the top end of the lower cross-shaped suspension plate 8, a driven pulley rotatably installed inside the U-shaped end seat 902, and a belt installed between the driving pulley and the driven pulley. One end of the belt is fixedly connected to the bottom end of the double-sliding table 903;

[0050] The pulley-type position adjustment assembly 14 drives the double-sliding table 903, the bevel gear 1203, and the opening assembly 12 to move in the extending direction of the steel column 901 through the belt to change the opening position of the opening assembly 12. During this process, the hollow rotating shaft 1002 and the external key shaft 1004 perform telescopic actions, and the hollow rotating shaft 1002 and the external key shaft 1004 still transmit the power of the bevel gear multi-directional transmission assembly 11 to the opening assembly 12, ensuring that the opening assembly 12 can still normally receive the rotating power from the main shaft 4 and the bevel gear multi-directional transmission assembly 11 after the distance adjustment is completed;

[0051] The multi-position rotary drive unit 13 includes a hanger 1301 installed at the bottom end of the lower cross-shaped suspension plate 8, a worm and worm gear reduction motor 1302 installed at the center position of the bottom end of the hanger 1301, and a helical gear transmission structure 1303 installed at the output end of the worm and worm gear reduction motor 1302 for driving multiple driving pulleys to rotate synchronously. When controlling the opening point positions of each opening assembly 12, the staff turns on the worm and worm gear reduction motor 1302 in the multi-position rotary drive unit 13 to work. Then, the worm and worm gear reduction motor 1302 drives multiple pulley-type position adjustment assemblies 14 to work together through the helical gear transmission structure 1303. The synchronous operation of multiple pulley-type position adjustment assemblies 14 ensures the accuracy of each operation point, avoids error accumulation caused by independent adjustment, makes the adjustment of each opening assembly 12 consistent, and ensures the overall processing accuracy and consistency.

[0052] Before the operation of the embodiments of the present application officially starts, the staff need to conduct a comprehensive inspection of the device. First, ensure that all components are correctly installed, and check the operating status of the multi-bit rotary drive unit 13, pulley-type position adjustment assembly 14, bevel gear multi-directional transmission assembly 11, keyway-type telescopic transmission shaft 10, and screw rod lifting module 7 to ensure that all components operate normally under no-load conditions. Finally, check whether the rotation and traction range of the pulley-type position adjustment assembly 14 meet the design requirements to ensure that there is no jamming phenomenon in each transmission component. After confirming that all parts of the device are correct, the operator adjusts the positions of the multiple opening assemblies 12. At this time, the staff drive each pulley-type position adjustment assembly 14 to work through the multi-bit rotary drive unit 13. By using the coordinated work of the multi-bit rotary drive unit 13 and the pulley-type position adjustment assembly 14, the staff control the opening points of the opening assemblies 12 according to the size and processing requirements of the offshore wind power flange workpiece until each opening assembly 12 reaches the predetermined operation requirements driven by the pulley-type position adjustment assembly 14. During this process, the opening assemblies 12 are still power-connected to the bevel gear multi-directional transmission assembly 11 through the keyway-type telescopic transmission shaft 10. After adjusting the positions of the opening assemblies 12, the staff start the pulley drive assembly 6 to work. The pulley drive assembly 6 drives the main shaft 4 to rotate. Then, the rotation power of the main shaft 4 is transmitted to each keyway-type telescopic transmission shaft 10 through the bevel gear multi-directional transmission assembly 11. Subsequently, the bevel gear multi-directional transmission assembly 11 and the keyway-type telescopic transmission shaft 10 evenly distribute the power to each opening assembly 12 to ensure that the multiple opening assemblies 12 perform drilling operations synchronously. When the multiple opening assemblies 12 have been debugged and obtained driving power, the staff start the drilling operation. By operating the screw rod lifting module 7, the rear bracket 2, front bracket 3, upper suspension plate 5, lower cross suspension plate 8, double-column truss 9, and multiple opening assemblies 12 are synchronously lowered to reach the accurate working height. During this process, the staff should adjust the drilling speed and depth parameters of the opening assemblies 12 according to the processing requirements and monitor the drilling progress of each opening assembly 12. And during the drilling process, the operator needs to regularly check the condition of the workpiece to ensure the accuracy and quality of the drilling. And the staff should adjust the operating state of the machine in a timely manner according to the monitored data fed back in real time to handle possible abnormal situations, such as drill bit blockage, working errors, etc. When the multi-point processing task is completed, the staff will perform the shutdown operation of the device and clean the device, especially the drilling area, to remove possible residual metal chips or other debris to prevent damage to the device.
