Description

Technical Field

[0001] The invention relates to the technical field of wind power tower welding, and in particular to an auxiliary device for welding cylinder sections of an offshore wind power tower. Background Art

[0002] The main function of the tower barrel segment welding auxiliary device is to help with precise docking, stable support, and smooth rotation of the barrel segment, ensuring welding quality and improving production efficiency. Specifically, it can accurately dock two barrel segments to prevent welding defects caused by gaps or misalignments; and through the rotation function, it is convenient for operators to perform uniform welding at different positions of the barrel segment to reduce manual errors. From the structural principle, the tower barrel welding auxiliary device is mainly composed of four parts: docking system, rotation system, support and fixing structure, and control system. The docking system ensures the precise docking of the two barrel segments through hydraulic or mechanical devices to avoid misalignment or gaps; the rotation system is driven by electric, hydraulic or pneumatic means to achieve smooth rotation of the barrel segment and facilitate the welding process; the support structure provides strong support through hydraulic supports or adjustable trays to prevent deformation caused by thermal stress; the control system uses PLC automation control, combined with sensors and laser docking technology, to monitor and adjust the position and status of the barrel segment in real time;

[0003] As disclosed in the authorization announcement number CN117206770B, a wind power tower barrel section welding auxiliary device includes a workbench, a barrel section to be welded and a surrounding traction component, wherein the barrel section to be welded is located above the workbench, and the surrounding traction component is arranged on the workbench, and the surrounding traction component includes a wax seal coating unit, a synchronous detection unit, a main rotating part, an auxiliary rotating part and a connecting straight rod, which can maintain a stable transmission relationship with the outer wall of the barrel section to be welded by means of the bonding relationship between the wax seal coating unit and the outer wall of the barrel section to be welded, and the setting of the traction motor, gear and gear ring can provide sufficient driving force, so that the barrel section to be welded will not rotate out of place during the welding process, resulting in insufficient weld filling. However, the above technical scheme is mainly used to keep the tower barrel section in a state of self-rotation during use. However, when two adjacent After the welding operation of the tower barrel section is completed in the device, the tower barrel section remains in the device, and external hydraulic equipment and lifting equipment are required to gradually move the two or more tower barrel sections in the welded state out of the device, that is, to help the tower barrel section move axially, but the working speed of the hydraulic equipment is usually slow, especially when dealing with large-sized and heavy tower barrel sections, the action of the hydraulic system needs to be carefully adjusted to avoid collision or damage to the barrel section, this adjustment often takes up a lot of time, and when the lifting equipment moves the tower barrel section, the balance and load capacity of the lifting point must also be considered. The weight of the wind turbine tower is huge, and the size of the tower barrel section is not small. Usually, multiple lifting points are required to maintain the balance of the tower barrel section, which can easily cause the tower barrel section to tilt or shift, thereby affecting the accuracy and speed of movement.

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Two symmetrical support rings 2 are provided inside the left and right working areas, and a plurality of screw positioning structures 5 for supporting tower barrel sections are evenly installed on the outer wall of one side of the support ring 2, and a plurality of C-shaped long beams 6 with equal intervals are fixed between two adjacent support rings 2, and one side outer wall of the C-shaped long beam 6 is arched toward the direction of the central axis of the support ring 2, and a plurality of C-shaped long beams 6 are located between two adjacent support rings 2. On the one hand, the two support rings 2 are connected to keep the two adjacent support rings 2 from rotating under the drive of the bilateral rotary drive module 4, and on the other hand, since the C-shaped long beam 6 is arched toward the direction of the central axis of the support ring 2, a gap portion is formed on the side of the C-shaped long beam 6 away from the central axis of the support ring 2, and the existence of the gap portion provides space for the action of the pneumatic two-stage traction module 9 and the barrel section picking mechanism 10;

[0035] A bilateral rotary drive module 4 is provided on one inner wall of the dual-zone auxiliary frame 1 for driving the four support rings 2 to rotate synchronously and at a constant speed;

[0036] A circular base 8 is installed at the bottom of the dual-zone auxiliary frame 1, and a cylinder segment picking mechanism 10 is arranged on one side of the interior of the circular base 8, and a pneumatic two-stage traction module 9 for driving the cylinder segment picking mechanism 10 to move in the X-axis direction is installed on the other side of the interior of the circular base 8, and a PLC controller 7 is installed on one side of the surface of the dual-zone auxiliary frame 1, and the output end of the PLC controller 7 is electrically connected to the input end of the bilateral rotary drive module 4, the pneumatic two-stage traction module 9, and the cylinder segment picking mechanism 10;

[0037] A cylinder segment blocking mechanism 3 for blocking the cylinder segment in the right working area is arranged on the outer wall of one side of the dual-zone auxiliary frame 1. The cylinder segment blocking mechanism 3 comprises a screw lifting module 301 installed on the inner wall of one side of the dual-zone auxiliary frame 1, a connecting plate 302 fixed at the moving end of the screw lifting module 301, and a U-shaped blocking arm 303 slidably installed on the outer wall of one side of the dual-zone auxiliary frame 1. One end of the U-shaped blocking arm 303 is fixedly connected to the outer wall of one side of the connecting plate 302. After the cylinder segment is loaded into the support ring 2, the PLC controller 7 is used to start the screw lifting module 301, and the connecting plate 302 and the U-shaped blocking arm 303 are driven downward by the screw lifting module 301, so that the U-shaped blocking arm 303 is used to block the loading opening position of the dual-zone auxiliary frame 1 to prevent the cylinder segment loaded in the support ring 2 from escaping from the dual-zone auxiliary frame 1.

[0038] Embodiment 2, based on embodiment 1, Figure 3 , Figure 7 , Figure 8 and Fig. 9 It is shown that support ring plates 101 are fixed on both the left and right inner walls of the dual-zone auxiliary frame 1, and the top walls of the two support ring plates 101 in the same Y-axis direction are slidably matched with the arcuate outer wall of the support ring 2. During the rotation of the support ring 2, the support ring plates 101 on the two inner walls of the dual-zone auxiliary frame 1 support the support ring 2, thereby improving the rotation stability of the support ring 2;

[0039] The screw rod positioning structure 5 comprises a nut pair 501 fixed on the outer wall of one side of the support ring 2, a threaded shaft 503 threadedly installed inside the nut pair 501, and convex seats 502 fixed on the outer wall of the support ring 2 on both sides of the nut pair 501, an elastic guide 506 is installed on the outer wall of the convex seat 502 close to the center point of the support ring 2, a support plate 504 is slidably installed on the convex seat 502, one end of the threaded shaft 503 is rotatably connected to the outer wall of one side of the support plate 504, and two symmetrical supporting arms 505 are installed on the outer wall of the support plate 504 close to the center point of the support ring 2;

[0040] After the cylinder section to be welded is assembled into the two support rings 2, the staff can manually operate the threaded shaft 503, and the threaded shaft 503 drives the support plate 504 and the support arm 505 to approach or move away from the nut pair 501. By adjusting the multiple screw positioning structures 5, the cylinder section and the support ring 2 are made coaxial, which provides a balanced support force for the cylinder section to avoid the cylinder section from being offset or unevenly stressed due to position errors; the multiple screw positioning structures 5 on the outer wall of the support ring 2 can accurately dock the cylinder section and the support ring 2 to the predetermined position, ensuring that a perfect joint surface is formed between the cylinder sections during the welding process, reducing welding defects caused by inaccurate docking;

[0041] The bilateral rotary drive module 4 comprises a wheel frame 402 mounted on the two inner walls of the dual-zone auxiliary frame 1, a stepper motor 401 mounted on the outer wall of one side of the dual-zone auxiliary frame 1, and a transmission shaft 404 rotatably mounted between a plurality of wheel frames 402 in the same X-axis direction, a belt transmission structure 403 for driving the transmission shaft 404 to rotate is mounted on the output end of the stepper motor 401, a steel wheel 405 in contact with the outer peripheral surface of the support ring 2 is fixed on the surface of the transmission shaft 404, the wheel frame 402, the support plate 504, and the support arm 505 are all made of aluminum alloy components, the PLC controller 7 controls the stepper motor 401 to work according to the set direction, speed, angle, and response time, and the stepper motor The rotational power of the machine 401 is transmitted to the transmission shaft 404 through the belt transmission structure 403. Since the belt transmission structure 403 drives the steel wheel 405 to rotate, and each steel wheel 405 is in contact with the outer peripheral surface of the support ring 2, the steel wheel 405 is used to drive the support ring 2 to rotate. It can synchronously control the rotation of the support ring 2 and the cylinder section during the entire assembly process. Since the two support rings 2 in the left and right working areas of the dual-zone auxiliary frame 1 maintain the same speed, the contact surface of the two cylinder sections can be kept stable during the welding process, avoiding welding defects caused by uneven rotation or human factors, reducing common welding defects such as pores and cracks, thereby improving the quality of welding.

[0042] Embodiment 3, based on embodiment 1, Fig.10 and Fig.11It is given that the pneumatic two-stage traction module 9 includes a long-stroke cylinder 901 fixed to one side of the inner part of the circular base 8, a double-headed gear arm 902 installed at the top of the piston rod of the long-stroke cylinder 901, a lower rack 904 fixed on the two inner walls of the circular base 8, and a U-shaped guide frame 903 slidably installed on the upper surface of the circular base 8, upper racks 905 are fixed on the outer walls of both sides of the U-shaped guide frame 903, the double-headed gear arm 902 is meshed with the lower rack 904 and the upper rack 905, the long-stroke cylinder 901 pushes the double-headed gear arm 902 to move in the direction of the barrel segment blocking mechanism 3, the barrel segment picking mechanism 10 is installed on the outer wall of one side of the U-shaped guide frame 903, guide plates 801 are fixed on both sides of the top of the circular base 8, rollers slidingly matched with the guide plates 801 are installed on the outer wall of the U-shaped guide frame 903, and rectangular grooves for the rollers to be embedded and rolled are provided on the outer wall of the guide plate 801;

[0043] Compared with the traditional mechanical traction method, the pneumatic two-stage traction module 9 can provide more precise force adjustment during the traction process, avoiding the traction deviation caused by equipment wear or improper manual operation in the traditional method, and the traction force is always kept stable, avoiding the deformation or position displacement of the cylinder section caused by insufficient or uneven moving power;

[0044] The double-headed gear arm 902 includes a longitudinal arm 9021 fixed to the top of the piston rod of the long-stroke cylinder 901, a rotating shaft 9022 rotatably mounted on the outer wall of one side of the longitudinal arm 9021 through a bearing seat, and a gear monomer 9023 fixed at both ends of the rotating shaft 9022, and the gear monomer 9023 is meshed with the lower rack 904 and the upper rack 905;

[0045] After the welding of the cylinder section is completed by the staff, the staff turns on the long-stroke cylinder 901 in the pneumatic two-stage traction module 9 through the PLC controller 7, and the piston rod of the long-stroke cylinder 901 drives the double-headed gear arm 902 to move in the direction of the cylinder section blocking mechanism 3. Since the gear in the double-headed gear arm 902 is meshed with the lower rack 904 and the upper rack 905, and the lower rack 904 is in a fixed state, the gear of the double-headed gear arm 902 will be driven to rotate by the lower rack 904 during the translation process, and then the double-headed gear arm 902 drives the upper rack 905 and the U-shaped guide frame 9 03 slides in the direction of the barrel segment blocking mechanism 3 until the double-headed gear arm 902 and the upper rack 905 are pushed to the limit position, which is determined by the length of the long-stroke cylinder 901. At this time, the barrel segment picking mechanism 10 is actuated, and the barrel segment picking mechanism 10 actively contacts the lower surface of one of the barrel segments and picks up the barrel segment. After the barrel segment picking mechanism 10 and the barrel segment are connected, the piston rod of the long-stroke cylinder 901 retracts and resets, and then the pneumatic two-stage traction module 9 pulls the barrel segment axially through the barrel segment picking mechanism 10 until the barrel segment is partially moved out of the dual-zone auxiliary frame 1 to facilitate the access to the next barrel segment.

[0046] Embodiment 4, based on embodiment 3, Fig.12 It is given that the barrel section picking mechanism 10 includes two right-angle arms 1001 installed on the outer wall of one side of the U-shaped guide frame 903, a steel frame 1002 fixed to the same end of the two right-angle arms 1001, and two second cylinders 1003 installed on the top of the steel frame 1002, the top of the piston rods of the two second cylinders 1003 are fixed with double-slope I-shaped plates 1004, both sides of the top of the double-slope I-shaped plates 1004 are fixed with straight arms 1005, both sides of the top of the straight arms 1005 are installed with vacuum suction cups 1006, the length of the straight arms 1005 is 60cm to 200cm, and the right-angle arms 1001 serve the purpose of connecting the steel frame 1002 and the U-shaped guide frame 903;

[0047] After the cylinder segment picking mechanism 10 is pushed by the pneumatic two-stage traction module 9 and moves axially, the staff drives the double-slope I-plate 1004, the straight-mouth arm 1005 and the vacuum suction cup 1006 upward through the second cylinder 1003 until the vacuum suction cup 1006 contacts the outer wall surface of the cylinder segment. The vacuum suction cup 1006 generates negative pressure through an external vacuum pump or air source, and with the help of the sealing between its own suction cup and the cylinder segment, the suction cup can be firmly adsorbed on the cylinder segment. Since the vacuum suction cup 1006 can work on cylinder segments of different materials and surface smoothness, the contact sealing between the cylinder segment and the suction cup surface can be ensured during transportation, thereby avoiding instability or unsafe conditions in the cylinder segment.

[0048] When the embodiment of the present application is in use, the tower barrel section is first loaded, the lifting equipment is arranged on one side of the barrel section blocking mechanism 3, the tower barrel section is lifted by the lifting equipment so that the tower barrel section and the support ring 2 are in a coaxial state, and the tower barrel section is pushed into the depth of the double-zone auxiliary frame 1. In the process of pushing the tower barrel section into the double-zone auxiliary frame 1, the support ring 2 and the C-shaped long beam 6 jointly assume the task of supporting the barrel section. The support ring 2 surrounds the outer periphery of the barrel section to stably hold up the barrel section, and a plurality of C-shaped long beams 6 further enhance the support of the barrel section on the basis of the support ring 2 through bearing force and stability, so as to avoid instability of the barrel section during rotation and movement. When the barrel section is fixed on the double-zone auxiliary frame 1, the support ring 2 and the C-shaped long beam 6 jointly assume the task of supporting the barrel section. After the two support rings 2 in the left working area of ​​the auxiliary frame 1 are installed, the staff also installs a cylinder segment into the two support rings 2 in the right working area of ​​the dual-zone auxiliary frame 1 according to the same steps, until the opposite ends of the two tower barrel segments are located at the spacing portion 102 and maintain contact. In this process, the screw positioning structure 5 ensures that the cylinder segment is coaxial with the support ring 2 through precise mechanical adjustment, providing an accurate docking position for subsequent welding. After the cylinder segment is fixed in the support ring 2, it is necessary to make the tower barrel segment enter a rotating state to facilitate welding at the docking point. The staff starts the operation of the double-sided rotary drive module 4 through the PLC controller 7, and the double-sided rotary drive module 4 drives multiple support rings 2 and cylinder segments to rotate evenly. During the process, the PLC controller 7 adjusts the rotation speed and direction of the bilateral rotary drive module 4 to ensure that the cylinder segment is stable during the rotation process and that the butt joint surface of the cylinder segment is in a suitable welding position. During the self-rotation of the tower cylinder segment, the staff can perform welding operations at the interval 102. After the welding operation is completed, the cylinder segment is axially moved to move the welded cylinder segment out of the working area and prepare to connect the next cylinder segment. The pneumatic two-stage traction module 9 is driven by gas pressure to provide a smooth traction force to move the cylinder segment forward accurately along a predetermined path. The cylinder segment picking mechanism 10 is responsible for picking up the cylinder segment from the support ring 2 and connecting it to the traction module, so that the cylinder segment does not become loose during the movement. Movement or tilt, compared with traditional hydraulic equipment, the pneumatic system has a fast response speed, easy operation, and can maintain high stability, and the cylinder segment picking mechanism 10 can accurately control the grabbing and releasing process of the cylinder segment to ensure the safe and stable movement of the cylinder segment. After the pneumatic two-stage traction module 9 and the cylinder segment picking mechanism 10 cooperate to complete the unloading of the cylinder segment, the staff continues to use the lifting equipment to place the new cylinder segment from the cylinder segment blocking mechanism 3 to the support ring 2. At this time, the cylinder segment blocking mechanism 3 moves up and resets without blocking the cylinder segment, so as to prepare for the next welding. At this time, the PLC controller 7 will dispatch all components again to ensure smooth and precise operation and ensure that the new cylinder segment can quickly enter the welding operation process.
