Description

Technical Field

[0001] This invention relates to the field of tower welding equipment technology, and specifically discloses a tower welding device for wind power generation construction. Background Technology

[0002] Wind power generation is an important form of power generation that relies on wind energy resources to achieve clean energy conversion and electricity production. It has advantages such as being green and environmentally friendly, renewable, and having low operating costs. It is one of the core development directions of the new energy industry. Wind turbine generators are mainly composed of core components such as blades, nacelles, generators, and towers. Among them, the tower, as the main supporting structure, plays an important role in supporting the nacelle, blades, and various auxiliary equipment. Its overall structural strength and the quality of the butt welds directly determine the operational stability, service life, and operational safety of the wind turbine generator. The tower is generally made up of multiple tower sections welded together. Therefore, the welding process of the tower sections is a core process in the production and manufacturing of wind power equipment.

[0003] The wind power tower welding device is a specialized processing equipment specifically designed for the docking of wind turbine tower sections. It is mainly used to complete the docking and positioning, welding, and other processing procedures between different tower sections. It is suitable for the processing conditions of large-size and heavy wind turbine towers and is widely used in wind power equipment manufacturing plants, wind power construction sites, and other places. It can complete the docking, fixing, and welding operations of tower sections and is a key piece of equipment to ensure the processing quality of wind turbine towers and promote the mass production and on-site construction of wind power equipment.

[0004] In the production, processing, and on-site construction of wind turbine towers, the positioning accuracy of tower section docking, transportation safety, welding operation mode, and the effectiveness of welding wire storage and management directly affect the quality of the finished tower, operational safety, and overall processing efficiency. Currently, the tower welding equipment used in wind power construction faces critical issues that urgently need to be addressed in practical applications. Existing tower section welding equipment has a simple positioning structure and lacks a matching positioning plate structure for opposing clamping, making it difficult to accurately align and clamp two sets of tower sections. This leads to easy displacement of the tower section docking position, making it impossible to ensure precise alignment of the joint with the welding station, significantly reducing welding accuracy and easily causing quality problems such as welding misalignment and weld seam deviation. Simultaneously, traditional equipment lacks an integrated flipping and shifting structure, making unloading and transportation of tower sections after welding inconvenient. Furthermore, the lack of continuous compression and limiting during transportation makes tower sections prone to loosening and falling, resulting in poor operational safety and stability. Traditional welding structures often rely on a single movement pattern, with most operations depending on the workpiece or welding torch moving in only one direction. This lack of coordination between workpiece rotation and torch reciprocating movement results in limited welding coverage, dead angles, incomplete weld joints, and potential for missed or incomplete welds. Furthermore, the uniformity and overall efficiency of welding are low, making it difficult to meet the high-quality welding requirements for tower joints. In addition, traditional welding wire reels lack a dedicated locking structure. Vibrations during welding operations and workpiece relocation can cause the wire reel to rotate freely, leading to loose and misaligned wires. This not only disrupts the initial wire arrangement and affects equipment cleanliness but also causes feeding delays and misalignment during subsequent welding operations. Manual re-adjustment of the wires is required, significantly increasing auxiliary work time and reducing the continuity and efficiency of the overall welding process. Therefore, a tower welding device for wind power generation construction was invented to address these shortcomings. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to improve welding efficiency, avoid leaving welding dead corners, prevent the tower from falling during the process of moving the welded tower, limit the position of the welding wire after welding to facilitate the next welding work, and provide a tower welding device for wind power construction.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a tower welding device for wind power generation construction, comprising two parallel tracks.

[0007] Two sliding brackets are slidably mounted on two rails, each used to install a tower section.

[0008] The clamping assembly, mounted on the rail, is capable of clamping the two tower sections.

[0009] The flipping assembly, mounted on a sliding bracket, enables the tower section to be flipped.

[0010] The upper frame, located above the tower section, has a welding gun slidably mounted on it.

[0011] The reciprocating moving component is mounted on the upper frame and connected to the welding gun, enabling the welding gun to move back and forth along the upper frame.

[0012] The wire spool and the locking assembly are both mounted on the reciprocating motion assembly. The locking assembly can lock the wire spool to prevent it from rotating.

[0013] Furthermore, the clamping assembly includes a double-headed motor fixedly mounted on a track. Each of the two output ends of the double-headed motor is fixedly mounted with a first helical rod. The two first helical rods are respectively connected to a sliding bracket and form a helical engagement. A tilting frame is fixedly mounted on the sliding bracket, and a positioning plate is rotatably mounted on the tilting frame. The positioning plate is used to position the outer port of the corresponding tower section.

[0014] Furthermore, the positioning plate is integrally formed from two coaxial cylinders of different diameters and is coaxial with the tower section. The outer surface diameter of the smaller cylinder is equal to the inner wall diameter of the tower section.

[0015] Furthermore, the tilting frame includes a positioning frame and a first connecting block. Both the positioning frame and the first connecting block are rotatably mounted on the sliding bracket. Both the positioning frame and the first connecting block are provided with a threaded hole. The two threaded holes are interconnected. A first fastening bolt is installed in the threaded hole. The fastening bolt enables a fast connection between the positioning frame and the first connecting block.

[0016] Furthermore, the flipping assembly includes a first motor fixedly mounted on the first connecting block and a drive shaft rotatably mounted on the positioning frame; a splined shaft is fixedly mounted at the output end of the first motor, a first gear is fixedly mounted on the outer surface of the splined shaft, a second gear meshing with the first gear is slidably mounted on the outer surface of the drive shaft, a synchronous belt is connected to the outer surface of the drive shaft, and the drive shaft is connected to the positioning disc through the synchronous belt to form a belt drive.

[0017] Furthermore, a positioning groove is provided on the outer surface of the drive shaft, and two positioning holes arranged axially on the inner wall of the positioning groove are provided. A slider fixedly connected to the second gear is slidably installed on the inner wall of the positioning groove, and a vertical shaft that can be inserted into any positioning hole is slidably installed on the outer surface of the slider.

[0018] Furthermore, the upper frame includes a detachably connected movable frame and a second connecting block. The movable frame is rotatably mounted on one track, and the second connecting block is fixedly mounted on another track. The movable frame and the positioning frame are respectively mounted on different tracks. The reciprocating moving assembly includes a second motor fixedly mounted on the movable frame. A second helical rod rotatably mounted on the movable frame is fixedly mounted at the output end of the second motor. A mounting frame that forms a helical engagement with the second helical rod is slidably mounted on the movable frame. An insertion hole is provided on the side of the mounting frame. A welding gun is mounted on the mounting frame. A welding wire spool is rotatably connected to the mounting frame. A follower cylinder is also fixedly mounted on the mounting frame. The welding wire on the welding wire spool passes through the follower cylinder and extends to the welding gun. A third motor is fixedly mounted on the mounting frame. The output end of the third motor is fixedly connected to the welding wire spool.

[0019] Furthermore, a limiting shaft is fixedly mounted on the output end of the third motor and rotatably mounted on the mounting bracket. The limiting shaft is fixedly connected to the welding wire spool. Multiple locking holes are provided on the outer surface of the limiting shaft along the circumferential direction. Each locking hole has a rounded corner on its edge. The rounded corners of every two adjacent locking holes are connected to each other. The inner diameter of the insertion hole is equal to the inner diameter of the locking hole. The axis of the insertion hole is perpendicular to the axis of the limiting shaft and is located in the same plane.

[0020] Furthermore, the locking assembly includes a U-shaped hook that slides on the mounting bracket and a locking electromagnet that is fixedly mounted on the mounting bracket.

[0021] Furthermore, the U-shaped hook is composed of a long rod, an arc-shaped rod, and a short rod that are fixedly connected in sequence. The end of the short rod facing the locking electromagnet is hemispherical. When the locking electromagnet is activated, the short rod can be inserted into the insertion hole and the locking hole in sequence under the magnetic attraction of the locking electromagnet, thereby completing the locking of the limit shaft.

[0022] Compared with the prior art, the beneficial effects of this application are as follows: (1) The present invention uses a pressing component to drive two positioning plates to move closer to each other, thereby pressing the two tower sections together. At the same time, the proximity of the two positioning plates makes the connection point of the two tower sections directly below the welding gun, thereby improving the welding accuracy. Meanwhile, the rotation component and the two positioning plates work together to rotate the positioning frame. The two positioning plates and the positioning frame work together to move the welded tower section out. The squeezing of the positioning plates prevents the tower section from falling off during the movement.

[0023] (2) The present invention feeds the welding wire between the welding gun and the tower section by rotating the welding wire reel, and achieves the relative movement between the welding gun and the tower section by the cooperation of the first motor driving the tower section to rotate and the second motor driving the welding gun to reciprocate. This improves the welding efficiency of the welding gun at the connection of the two tower sections. At the same time, the reciprocating movement of the welding gun is used to perform multiple welding at the connection of the two tower sections, avoiding leaving welding dead corners.

[0024] (3) The welding wire spool can be controlled by locking components. After the processing is completed, the welding wire spool is locked to prevent the vibration caused by the movement of the tower section after the welding is completed. This fixes the position of the welding wire and facilitates the next welding operation. Attached Figure Description

[0057] The working principle of this invention is as follows: (a) Before starting work, remove the second fastening bolt 407 from the second connecting block 405 and the moving frame 401. Then, use the second anti-slip handle to rotate the moving frame 401 around the fixed frame 203. Next, place the two tower sections 101 on the sliding bracket 202 respectively. Then, use the second anti-slip handle to return the moving frame 401 to its original position. Secure the second connecting block 405 and the moving frame 401 together using the second fastening bolt 407 and the connecting plate 406. Then, start the double-head motor 205. The double-head motor 205 drives the first spiral rod 206 to... The two sliding brackets 202 move closer to each other, and the sliding brackets 202 drive the two positioning brackets 303 to move closer to each other through the fixed rod 304. This causes the smaller cylinder of the positioning plate 301 to extend into the tower section 101, and the larger cylinder of the positioning plate 301 presses the two tower sections 101 together. After the two positioning plates 301 press the two tower sections 101 together, the dual-head motor 205 stops working, and the push of the two positioning plates 301 makes the connection point of the two tower sections 101 directly below the welding gun 506, thereby improving the accuracy of welding.

[0058] (ii) The first motor 316 starts. At the same time as the first motor 316 starts, it sends an electrical signal to the electromagnet on the inner wall of the positioning hole 311. At this time, the vertical shaft 318 is attracted by the electromagnet in the positioning hole 311, thereby realizing the fixed connection between the second gear 308 and the transmission shaft 309. The first motor 316 drives the transmission shaft 309 to rotate through the meshing of the first gear 306 and the second gear 308. The transmission shaft 309 drives the positioning disk 301 to rotate through the synchronous belt 317, thereby driving the two tower sections 101 to rotate.

[0059] (III) Simultaneously, the second motor 502, welding gun 506, third motor 510, and power motor 523 start at the same time. Power motor 523 drives two rolling wheels 520 to rotate in opposite directions. When the third motor 510 starts, it drives the welding wire reel 512 to rotate via the limiting shaft 515. The welding wire on the reel 512, under the action of the two rolling wheels 520, passes through the following cylinder 509 and is fed between the welding gun 506 and the tower section 101. When the second motor 502 starts, it drives the sliding cylinder 504 to slide along the inner wall of the limiting groove 402 via the second spiral rod 503. When a set of photoelectric detectors 501 at the end furthest from the second motor 502 detects the marking plate 505... When the photoelectric detector 501 sends an electrical signal to the second motor 502, the second motor 502 rotates in the opposite direction, driving the sliding cylinder 504 to move along the inner wall of the limiting groove 402 towards the direction closer to the second motor 502 via the second screw rod 503. When a set of photoelectric detectors 501 near one end of the second motor 502 detects the marker plate 505, the photoelectric detector 501 sends an electrical signal to the second motor 502, causing the second motor 502 to rotate in the forward direction, driving the sliding cylinder 504 to move along the inner wall of the limiting groove 402 away from the second motor 502 via the second screw rod 503, thus completing the reciprocating sliding of the sliding cylinder 504 along the inner wall of the limiting groove 402.

[0060] (iv) When the sliding cylinder 504 slides back and forth along the inner wall of the limiting groove 402, it drives the welding gun 506 and the following cylinder 509 to move back and forth. At this time, the distance between the outer surface of the tower section 101 and the detection part of the distance measuring instrument is measured by the distance measuring instrument. The distance measuring instrument inputs the detection result into the control circuit. The control circuit controls the extension and retraction of the electric cylinder extension end through the detection result, thereby controlling the distance between the conductive nozzle of the welding gun 506 and the outer surface of the tower section 101. The conductive nozzle generates a high temperature arc to melt the welding wire and the welding position of the workpiece, thereby completing the welding of the connection between the two tower sections 101. The relative movement of the welding gun 506 and the tower section 101 improves the welding efficiency of the welding gun 506 at the connection between the two tower sections 101. At the same time, the reciprocating movement of the welding gun 506 is used to perform multiple welding at the connection between the two tower sections 101, avoiding leaving welding dead corners.

[0061] (V) After working for 20 minutes, the first motor 316, the third motor 510 and the power motor 523 stop working. At this time, the welding wire stops moving. The first motor 316 sends an electrical signal to the photoelectric detector 501. At this time, the two photoelectric detectors 501 on the side away from the second motor 502 stop working. At this time, the second motor 502 pushes the mounting bracket 508 closer to the contact switch 507 through the sliding cylinder 504. When the mounting bracket 508 contacts the contact switch 507, the second motor 502 stops working. At this time, the contact switch 507 sends an electrical signal to the locking electromagnet 511. The locking electromagnet 511 starts and attracts the U-head hook 514 through the magnetic force of the locking electromagnet 511. At this time, the U-head hook 514 passes through the insertion hole 513 and the locking hole 516 respectively, thereby completing the locking of the limit shaft 515 and the welding wire spool 512, thus preventing the rotation of the welding wire spool 512.

[0062] (vi) After the first motor 316 stops working, it sends an electrical signal to the electromagnet in the positioning hole 311. At this time, the electromagnet in the positioning hole 311 is closed. Then, the vertical shaft 318 is pulled out from the inner wall of the positioning hole 311 near the second gear 308, and the slider 312 is moved to drive the second gear 308 to slide along the transmission shaft 309 away from the first gear 306. The vertical shaft 318 is inserted into the inner wall of the positioning hole 311 away from the second gear 308. At this time, the second gear 308 is disengaged from the first gear 306. Then, the first fastening bolt 315 is removed, the anti-slip handle is pushed, and the positioning frame 303 is pushed to rotate around the fixed rod 304, thereby lifting the welded tower section 101 out of the sliding bracket 202. Then, by moving the welded tower section 101 out, the positioning plate 301 squeezes to prevent the tower section 101 from falling during the movement.

[0063] (vii) By locking the limiting shaft 515 and the welding wire reel 512, the vibration generated when the tower section 101 is moved after welding is prevented from causing the welding wire reel 512 to rotate, thereby fixing the position of the welding wire and facilitating the next welding operation. After the tower section 101 is moved out after welding, the anti-slip handle is pushed to drive the positioning frame 303 back to its original position. Then, the first fastening bolt 315 is inserted into the threaded hole to complete the fastening connection between the first connecting block 305 and the positioning frame 303.
