Description

Technical Field

[0001] This utility model relates to the technical field of wind turbine tower welding platforms, and in particular to a gantry-type mobile welding platform for wind turbine tower processing. Background Technology

[0002] Wind turbine towers are key supporting structures in wind power systems. Their development is closely related to the global energy transition, the development of renewable energy, and the evolution of wind power technology. With increasing global concern about climate change, reducing dependence on fossil fuels and developing clean energy has become a global consensus. Wind power, as a technologically mature and economically viable renewable energy source, has experienced rapid development. Wind turbine towers, as the "skeleton" of wind turbines, are a crucial foundation for the large-scale development of wind power.

[0003] As disclosed in CN218081152U, a gantry-type mobile welding platform for wind turbine tower processing can weld wind turbine towers. However, during the welding process, weld slag of varying sizes may be generated. Larger weld slag may affect the effect of subsequent surface treatment. In addition, wind turbine towers usually require surface protection measures such as painting and galvanizing. If weld slag remains on the surface, it may affect the uniform adhesion of the coating. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a gantry-type mobile welding platform for wind turbine tower processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A gantry-type mobile welding platform for wind turbine tower processing includes two symmetrically arranged tooling platforms, and further includes: There are two gear ring motion mechanisms, and the two gear ring motion mechanisms are respectively set above two tooling platforms; The gear ring motion mechanism consists of an arc-shaped frame, racks, and a toothed core. There are two racks, which are symmetrically arranged at the top and bottom of the arc-shaped frame. The toothed core is located inside the arc-shaped frame and meshes with the two racks respectively. When the toothed core meshes with the two racks respectively, it causes the arc-shaped frame to reciprocate horizontally. There are two pointed chisels, which are positioned between two gear ring motion mechanisms. The two gear ring motion mechanisms are used to drive the pointed chisels to reciprocate horizontally.

[0006] As a further technical solution of this utility model, each tooling platform has two support frames fixed at both ends of its top. Rollers are rotatably installed between the two vertical sides of each support frame. The tooth core end face is fixedly installed at the center of the side of the roller through a connecting shaft. The roller is used to rotate the wind turbine tower. A drive motor is installed on the outside of each support frame. The output shaft of the drive motor is installed at the center of the side of the corresponding roller.

[0007] As a further technical solution of this utility model, two arc-shaped frames are slidably disposed between two symmetrical support frames on opposite sides. Connecting rods and movable telescopic rods are respectively horizontally fixedly installed on opposite sides of the two arc-shaped frames. Connecting blocks are fixedly installed at the ends of the connecting rods, and the surface of the movable telescopic rods is slidably disposed inside the connecting blocks through splines.

[0008] As a further technical solution of this utility model, each arc-shaped frame is connected to a slider at the bottom. The slider is L-shaped, and the corresponding support frame has a horizontal groove on its side. The slider is slidably installed inside the groove to assist the arc-shaped frame to move stably in the horizontal direction.

[0009] As a further technical solution of this utility model, a gantry frame is provided on the outside of both sides of the two tooling platforms, and two hydraulic cylinders are fixedly installed on the top of the gantry frame, with a lifting platform installed at the end of the hydraulic cylinders.

[0010] As a further technical solution of this utility model, a welding gun and a spring rod are installed on the lower surface of the lifting platform, and the spring rod is set perpendicular to the lifting platform. The fixed end and the telescopic end of the spring rod are connected by a spline to form a sliding connection. A welding slag scraper is fixedly installed on the telescopic end of the spring rod, and the working surface of the welding slag scraper is adapted to the welding position of the welding gun.

[0011] As a further technical solution of this utility model, each tooling platform is equipped with a walking wheel at each of its four corners, and a guide rail is horizontally arranged below the walking wheel, with the guide rail fixedly installed on the ground.

[0012] The beneficial effects of this utility model are as follows: This utility model utilizes a gear ring motion mechanism (including an arc-shaped frame, a rack, and a toothed core) to achieve horizontal reciprocating motion of the arc-shaped frame by alternating meshing with the rack when the toothed core rotates. A connecting rod and a movable telescopic rod are horizontally fixed between the opposite surfaces of the two arc-shaped frames, and the two are connected by a connecting block to ensure synchronous linkage. Two pointed chisels are set between the two arc-shaped frames. Through the horizontal reciprocating motion of the arc-shaped frames, the pointed chisels are driven to synchronously strike the welding slag on the wind turbine tower.

[0013] 2. This utility model uses a hydraulic cylinder and a lifting platform.

Detailed Implementation

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see the appendix Figure 1 - Appendix Figure 5A gantry-type mobile welding platform for wind turbine tower processing includes two symmetrically arranged tooling platforms 3, and further includes: a toothed ring motion mechanism 10 and a pointed chisel 14. There are two toothed ring motion mechanisms 10, and the two toothed ring motion mechanisms 10 are respectively arranged above the two tooling platforms 3. The toothed ring motion mechanism 10 is composed of an arc-shaped frame, a rack, and a tooth core 11. There are two racks, and the two racks are symmetrically arranged at the top and bottom of the arc-shaped frame. The tooth core 11 is arranged inside the arc-shaped frame, and the tooth core 11 will mesh with the two racks respectively. When the tooth core 11 meshes with the two racks respectively, it will cause the arc-shaped frame to move horizontally back and forth. There are two pointed chisels 14, and the two pointed chisels 14 are arranged between the two toothed ring motion mechanisms 10. The two toothed ring motion mechanisms 10 are used to drive the pointed chisels 14 to move horizontally back and forth. When the toothed core 11 rotates via the drive motor, it alternately meshes with the racks at the top and bottom of the arc-shaped frame. When meshing with the top rack, it drives the arc-shaped frame to move horizontally in a straight line, which in turn drives the pointed chisel 14 mounted on the arc-shaped frame to move horizontally in a straight line, striking the welding slag on the wind turbine tower. When meshing with the bottom rack, it drives the arc-shaped frame to move horizontally back, and the pointed chisel 14 returns to its original position with the arc-shaped frame. Through the continuous rotation of the toothed core 11, the arc-shaped frame achieves horizontal reciprocating motion, allowing the pointed chisel 14 to complete the striking action back and forth.

[0019] Please see the appendix Figure 2 - Appendix Figure 3 In a preferred embodiment, each tooling platform 3 has two support frames 6 fixed at both ends of its top. Rollers 7 are rotatably installed between the two vertical sides of each support frame 6. The end face of the tooth core 11 is fixedly installed at the center of the side of the roller 7 through a connecting shaft. The roller 7 is used to rotate the wind turbine tower. A drive motor is installed on the outside of each support frame 6. The output shaft of the drive motor is installed at the center of the side of the corresponding roller 7. When the drive motor is working, its output shaft drives the roller 7 to rotate. The roller 7 contacts the wind turbine tower and drives the tower to rotate through friction. At the same time, the roller 7 drives the toothed core 11 to rotate synchronously through the connecting shaft. When the toothed core 11 rotates, its teeth alternately mesh with the rack on the arc-shaped frame. Through the alternating change of the meshing position, the arc-shaped frame is driven to make linear reciprocating motion in the horizontal direction.

[0020] Please see the appendix Figure 1 - Appendix Figure 5 In a preferred embodiment, two arc-shaped frames are slidably disposed between two symmetrical support frames 6 opposite faces. A connecting rod 16 and a movable telescopic rod 18 are respectively horizontally fixedly installed on the opposite faces of the two arc-shaped frames. A connecting block 9 is fixedly installed at the end of the connecting rod 16, and the surface of the movable telescopic rod 18 is slidably disposed inside the connecting block 9 through a spline. The connecting rod 16 and the movable telescopic rod 18 form a spline sliding fit through the connecting block 9. The support frame 6 provides stable sliding support for the arc-shaped frame. The synchronous linkage of the two arc-shaped frames is achieved through the cooperation of the connecting rod 16, the movable telescopic rod 18 and the connecting block 9, ensuring that the two arc-shaped frames move in a coordinated manner in the horizontal direction.

[0021] Please see the appendix Figure 1 - Appendix Figure 3 In a preferred embodiment, each arc-shaped frame is connected to a slider 17 below. The slider 17 is L-shaped, and the corresponding support frame 6 has a horizontal groove on its side. The slider 17 is slidably installed inside the groove to assist the arc-shaped frame in moving stably in the horizontal direction. When the curved frame moves horizontally in a straight line, the slider 17 it drives moves horizontally synchronously in the groove; the slider 17 cooperates with the groove to provide guidance for the curved frame and ensure its stable movement in the horizontal direction.

[0022] Please see the appendix Figure 1 - Appendix Figure 2 In a preferred embodiment, a gantry frame 1 is provided on the outside of both sides of the two tooling platforms 3, and two hydraulic cylinders 2 are fixedly installed on the top of the gantry frame 1, with a lifting platform 4 installed at the end of the hydraulic cylinders 2; The hydraulic cylinder 2 drives the lifting platform 4 installed at the end through its telescopic movement to achieve vertical lifting and lowering, thereby adjusting the height of the lifting platform 4 and ensuring that the lifting platform 4 can operate stably in different height ranges of the tower.

[0023] Please see the appendix Figure 1 - Appendix Figure 2 In a preferred embodiment, a welding torch 8 and a spring rod 12 are installed on the lower surface of the lifting platform 4, and the spring rod 12 is set perpendicular to the lifting platform 4. The fixed end and the telescopic end of the spring rod 12 are connected by a spline fit to form a sliding connection. A welding slag scraper 13 is fixedly installed on the telescopic end of the spring rod 12, and the working surface of the welding slag scraper 13 is adapted to the welding position of the welding torch 8. Roller 7 rotates the wind turbine tower until the weld seam on the wind turbine tower is below the welding torch 8. Hydraulic cylinder 2 drives lifting platform 4 to move downward until the welding torch 8 is in contact with the weld seam on the wind turbine tower. During the welding process, roller 7 rotates the wind turbine tower synchronously to complete the welding work. During welding, slag scraper 13 moves synchronously with lifting platform 4 until it reaches the slag on the wind turbine tower to clean the slag remaining after the pointed chisel 14 knocks it. When slag scraper 13 encounters a large slag, the inclined surface of slag scraper 13 is pressed against spring rod 12, causing spring rod 12 to generate elastic force, causing spring rod 12 to contract and drive slag scraper 13 to pass over the large slag so that pointed chisel 14 can continue to knock the large slag. When slag scraper 13 passes over the large slag, spring rod 12 will return to its original position, allowing slag scraper 13 to return to the weld seam to continue working.

[0024] Please see the appendix Figure 1 - Appendix Figure 2 In a preferred embodiment, each tooling platform 3 is equipped with a walking wheel 15 at each of its four corners, and a guide rail 5 is horizontally arranged below the walking wheel 15 and fixedly installed on the ground. The four corner wheels 15 of each tooling platform 3 slide in cooperation with the guide rails 5 fixed on the ground. The tooling platform 3 is supported by the wheels 15, and the guide rails 5 guide and constrain the wheels 15, so that the tooling platform 3 can move horizontally stably and smoothly along the guide rails 5, thereby moving the wind turbine tower to the welding position so that the welding gun 8, the slag scraper 13 and the pointed chisel 14 can work.

[0025] When the operator places the wind turbine tower on the two tooling platforms 3, the four corner wheels 15 at the bottom of the tooling platform 3 are electrically driven to slide stably horizontally along the guide rails 5 fixed to the ground, moving the tooling platform 3 to the welding position of the wind turbine tower, completing the initial alignment of the equipment and the tower; then, the drive motor on the outside of the support frame 6 is started, and the output shaft of the drive motor synchronously drives the roller 7 and the toothed core 11 to rotate, wherein the roller 7 contacts the outer periphery of the wind turbine tower, and the friction drives the wind turbine tower to slowly rotate around its own axis. When the weld seam on the wind turbine tower rotates with the roller 7 to be directly below the welding torch 8, the hydraulic cylinder 2 at the top of the gantry frame 1 is activated, and the hydraulic cylinder 2... The telescopic motion drives the lifting platform 4 at the end to move vertically downwards until the welding torch 8 on the lower surface of the lifting platform 4 contacts the weld seam of the wind turbine tower. The welding torch 8 then begins welding. During the welding process, the roller 7 continuously drives the wind turbine tower to rotate slowly, allowing the welding torch 8 to continuously weld the entire circumferential weld seam. Then, the toothed core 11 rotates inside the arc-shaped frame, its teeth alternately meshing with the racks at the top and bottom of the arc-shaped frame. When meshing with the top rack, it drives the arc-shaped frame to move in a straight line horizontally, thereby driving the pointed chisel 14 mounted on the arc-shaped frame to move closer to the wind turbine tower, striking the weld slag on the surface of the wind turbine tower. When meshing with the bottom rack, it drives the arc-shaped core 11 to move in a straight line horizontally. The frame moves horizontally back, and the pointed chisel 14 returns to its original position with the curved frame, preparing for the next strike. During this process, the two curved frames are synchronized through the spline sliding cooperation formed by the connecting rod 16, the movable telescopic rod 18, and the connecting block 9 on opposite sides. The L-shaped slider 17 below the curved frame slides horizontally along the groove on the side of the support frame 6, providing guidance for the horizontal movement of the curved frame and ensuring that the two curved frames and the pointed chisel 14 always move in a coordinated and stable horizontal direction. Simultaneously with welding, the spring rod 12, vertically mounted on the lower surface of the lifting platform 4, moves synchronously with the lifting platform 4, and the slag scraper 13 at its telescopic end reaches the welding point of the wind turbine tower. At the slag site, the residual welding slag after being struck by the pointed chisel 14 is scraped and cleaned. If the welding slag scraper 13 encounters a large welding slag, the large welding slag will exert a squeezing force on the inclined surface of the welding slag scraper 13. This force is transmitted to the spring rod 12, causing the spring rod 12 to contract and generate elastic force, which in turn drives the welding slag scraper 13 to rise and pass over the large welding slag. At this time, the pointed chisel 14 can continue to strike the large welding slag. After the welding slag scraper 13 has completely passed over the large welding slag, the spring rod 12 releases its elastic force and resets, driving the welding slag scraper 13 back to the weld of the wind turbine tower to continue cleaning the residual welding slag generated by subsequent welding, until the welding and welding slag cleaning work of the entire weld is completed.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
