Description

Technical Field

[0001] This utility model belongs to the field of wind turbine manufacturing technology, and in particular relates to a welding device for wind turbines. Background Technology

[0002] A wind turbine is a device that converts wind energy into electrical energy. It typically consists of a tower, rotor, generator, converter, and controller. Wind-driven rotors convert wind energy into mechanical energy, which is then transmitted to the generator via a transmission system. The generator converts the mechanical energy into electrical energy. The converter is responsible for converting the electrical energy into a type suitable for the power grid, while the controller ensures the equipment operates safely and efficiently at different wind speeds. Wind turbines are mostly installed in areas with abundant wind energy, such as coastal areas, grasslands, or mountainous regions, providing clean and renewable electricity to the local area. This method of power generation is environmentally friendly and pollution-free, helping to reduce the use of fossil fuels and lower greenhouse gas emissions, making it an important component of sustainable energy. Wind turbine generators use a large number of pipes to form a pipeline system for transporting hydraulic oil and other substances. However, the pipes are cylindrical, and welding machines can only weld the top area of ​​the pipes. Repeated adjustments of the pipes are required to continue welding, which affects the efficiency of pipe welding. To address this, we have proposed a welding device for wind turbine generators. Utility Model Content

[0003] The purpose of this invention is to provide a welding device for wind turbine generators. Specifically, by setting an external support mechanism, the motor is started, causing a small spur gear to rotate. Then, through meshing, a large spur gear rotates counter-clockwise, causing a cylindrical protrusion to slide along the groove of the large spur gear and drive a supporting arc plate to slide outwards. Then, the transmission rod is rotated. Thus, the outward movement of the supporting arc plate supports the inner wall of the pipe from within, allowing the transmission rod to drive the pipe to rotate at a uniform speed. This reduces the time required to adjust the pipe, ensuring efficient pipe welding. This invention solves the problem that existing wind turbine generators use a large number of pipes that form a pipeline system to transport hydraulic oil and other substances. However, because these pipes are cylindrical, the welding machine can only weld the top area of ​​the pipe, requiring repeated adjustments to continue welding, thus affecting the efficiency of pipe welding.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a welding device for wind turbine generators, including an external support mechanism, which is used to support the inner wall of the pipe from the inside. A positioning mechanism is installed at the bottom of the external support mechanism and is used to position the pipe at the center of the equipment. The external support mechanism drives the pipe to rotate by its own rotation, thus assisting in the pipe welding process.

[0005] Furthermore, the external support mechanism includes an external support assembly, which is used to position the pipe from the center inside the pipe; An auxiliary component is mounted on the outside of the outer support component and is used to output power to the outer support component; When the auxiliary component is started, it is used to drive the external support component to rotate, so that the external support component drives the pipe to rotate at a uniform speed.

[0006] Furthermore, the positioning mechanism includes a positioning component, which is installed at the bottom of the external support component and is used to position the pipe from the front and back. A limiting component is installed on top of the positioning component, and the limiting component is used to restrict the movement of the positioning component to prevent the positioning component from deflecting when it moves; A welding assembly, mounted on top of a positioning assembly, is used for processing the pipe. Once the positioning component has positioned the pipe, the welding component can be activated to process the pipe, thereby improving the processing accuracy of the pipe.

[0007] Furthermore, the external support assembly includes two X-shaped protrusions, which are horizontally mirrored. Supporting arc plates are slidably connected inside each of the two X-shaped protrusions. A transmission rod is installed at the center of each X-shaped protrusion. A large spur gear is rotatably connected to the front of each X-shaped protrusion. Several grooves are opened inside the large spur gear, and cylindrical protrusions are slidably connected within these grooves. The cylindrical protrusions are installed together with the supporting arc plates. A small spur gear is meshed with the top of the large spur gear. The small spur gear extends outwards through the top of the X-shaped protrusion and is rotatably connected. A motor is installed on the left side of the top of the X-shaped protrusion, and the motor is connected to the small spur gear via a coupling. By setting up an electric motor, the rotation of the small spur gear can be controlled, and the rotation of the large spur gear can be controlled through the meshing connection between the large spur gear and the small spur gear, thereby controlling the contraction and release of the support arc plate. The right side of the transmission rod on the left is a slot, and the left side of the transmission rod on the right is a plug. The two transmission rods are connected together through the slot and the plug, which facilitates the synchronous rotation of the two transmission rods.

[0008] Furthermore, the auxiliary component includes two fixed square plates, which are mirror images of each other. The fixed square plates are installed on the side of the transmission rod that is far apart from each other. The fixed square plates are rotatably connected to the transmission rod. A connecting protrusion is installed on the bottom of the fixed square plate. A second motor is installed at the center of the right side of the left fixed square plate. The second motor is installed together with the transmission rod on the right side through a coupling. Both of the fixed square plates are equipped with rollers at their bottoms, which facilitates the movement of the fixed square plates. The connecting protrusion has an internal thread and is used to install the external support mechanism to the outside of the welding device using bolts.

[0009] Furthermore, the positioning component includes a component horizontal plate, and a gantry frame is installed on the left and right sides of the top of the component horizontal plate. A screw housing is installed on the top of the gantry frame, and a bidirectional screw is installed inside the screw housing. The front and back of the bidirectional screw pass through the screw housing and are rotatably connected. The front and back of the outer surface of the screw housing are threaded with irregularly shaped clamps, and a motor is installed on the front of the screw housing. By setting a threaded connection between the bidirectional screw and the irregularly shaped clamping plate, the irregularly shaped clamping plate can move as the bidirectional screw rotates. The two irregularly shaped clamps have curved surfaces on the sides that are close to each other, which allows the two irregularly shaped clamps to fit better against the outer surface of the pipe.

[0010] Furthermore, the limiting component has several irregularly shaped slide rails, and all of the irregularly shaped slide rails are opened on the top of the component's horizontal plate; The welding assembly includes a connecting rod, which is installed at the top center of the assembly's horizontal plate, and a welding machine is installed at the top center of the connecting rod. Rounded corner protrusions are fixedly connected to the bottom left and right sides of the component horizontal plate. The rounded corner protrusions of the component horizontal plate and the connecting protrusions are compatible with each other. By using bolts to pass through the rounded corner protrusions of the component horizontal plate and the supporting arc plate, the fixed square plate and the component horizontal plate can be tightly connected together. The irregularly shaped slide rail has an internally slidably connected irregularly shaped slider. The bottom of the irregularly shaped slider is fixedly connected to the bottom of the irregularly shaped clamping plate, which can prevent the irregularly shaped clamping plate from deflecting when it moves.

[0011] This utility model has the following beneficial effects: 1. This utility model, by setting an external support mechanism, specifically starts the motor and makes the small spur gear rotate, and then drives the large spur gear to rotate counterclockwise through meshing connection, so that the cylindrical protrusion slides along the groove of the large spur gear and drives the support arc plate to slide outward. Then, the transmission rod is rotated. In this way, the inner wall of the pipe can be supported from the inside by the outward movement of the support arc plate, so that the transmission rod can drive the pipe to rotate at a uniform speed, reducing the time for adjusting the pipe and ensuring the efficiency of pipe welding.

[0012] 2. This utility model sets up a positioning mechanism, specifically by starting the motor three to make the bidirectional screw rotate counterclockwise, and by driving the irregular clamping plate through the thread on the outer surface, so that the two irregular clamping plates move closer to each other. In this way, the pipe can be restricted to the center of the equipment by the two irregular clamping plates, preventing the pipe from deviating from the center during welding and ensuring that the pipe welding can be carried out stably.

[0018] Please see Figures 1-5As shown, this utility model is a welding device for wind turbine generators, including an outer support mechanism 1, which supports the inner wall of a pipe from the inside; a positioning mechanism 2, which is installed at the bottom of the outer support mechanism 1 and positions the pipe at the center of the device; wherein, the outer support mechanism 1 drives the pipe to rotate by its own rotation, providing assistance for pipe welding. The outer support mechanism 1 includes an outer support assembly 11, which positions the pipe from the center inside the pipe; and an auxiliary assembly 12, which is installed on the outside of the outer support assembly 11 and outputs power to the outer support assembly 11; wherein, when the auxiliary assembly 12 is started, it drives the outer support assembly 11 to rotate, so that the outer support assembly 11 drives the pipe to rotate at a uniform speed.

The external support assembly 11 includes two X-shaped protrusions 111, which are horizontally mirrored. A support arc plate 112 is slidably connected inside each X-shaped protrusion 111. A transmission rod 116 is installed at the center of each X-shaped protrusion 111. A large spur gear 114 is rotatably connected to the front of each X-shaped protrusion 111. Several grooves are formed inside the large spur gear 114, and cylindrical protrusions 113 are slidably connected within these grooves. The cylindrical protrusions 113 are mounted together with the support arc plate 112. A small spur gear 115 is meshed with the top of the large spur gear 114. The small spur gear 115 extends outwards through the top of the X-shaped protrusion 111 and is rotatably connected. A motor 117 is installed on the left side of the top of the X-shaped protrusion 111. The motor 117 is connected to... Small spur gears 115 are installed together; the motor 117 is started to make the small spur gears 115 rotate, and through the meshing connection, it drives the large spur gear 114 to rotate counterclockwise, so that the cylindrical protrusion 113 slides along the groove of the large spur gear 114, and drives the support arc plate 112 to slide outward. Then the transmission rod 116 is rotated. In this way, the outward movement of the support arc plate 112 can support the inner wall of the pipe from the inside, so that the transmission rod 116 can drive the pipe to rotate at a uniform speed, reducing the time for adjusting the pipe and ensuring the efficiency of pipe welding. Among them, the right side of the transmission rod 116 on the left side is a slot, and the left side of the transmission rod 116 on the right side is a plug. The two transmission rods 116 are connected together through the slot and the plug, so that the two transmission rods 116 can rotate synchronously.The auxiliary component 12 includes two fixed square plates 121, which are mirror images of each other. The fixed square plates 121 are installed on the opposite side of the transmission rod 116 and are rotatably connected to the transmission rod 116. A connecting protrusion 122 is installed on the bottom of the fixed square plate 121. A second motor 123 is installed at the center of the right side of the left fixed square plate 121. The second motor 123 is installed together with the transmission rod 116 on the right side via a coupling. The connecting protrusion 122 has an internal thread and is used to install the outer support mechanism 1 to the outside of the welding device using bolts. The positioning component 21 includes a component horizontal plate 211. A gantry frame 212 is mounted on the left and right sides of the top of the component horizontal plate 211. A screw housing 213 is mounted on the top of the gantry frame 212. A bidirectional screw 214 is installed inside the screw housing 213. The front and back of the bidirectional screw 214 penetrate the screw housing 213 and are rotatably connected. A special-shaped clamping plate 215 is threaded onto the front and back of the outer surface of the screw housing 213. A motor 216 is mounted on the front of the screw housing 213. The starting motor... Machine 3 216 causes the bidirectional screw 214 to rotate counterclockwise, and drives the irregular clamping plate 215 through the thread on the outer surface, so that the two irregular clamping plates 215 are brought closer to each other. In this way, the two irregular clamping plates 215 can restrict the pipe to the center of the equipment, prevent the pipe from deviating from the center during welding, and ensure that the pipe welding can be carried out stably. Among them, the side of the two irregular clamping plates 215 that are close to each other is provided with an arc surface, so that the two irregular clamping plates 215 can better fit together with the outer surface of the pipe. The limiting component 22 has several irregularly shaped slide rails 221, all of which are located on the top of the component horizontal plate 211; the welding component 23 includes a connecting rod 231, which is installed at the top center of the component horizontal plate 211, and a welding machine 232 is installed at the top center of the connecting rod 231; wherein, an irregularly shaped slider 222 is slidably connected inside the irregularly shaped slide rail 221, and the bottom of the irregularly shaped slider 222 is fixedly connected to the bottom of the irregularly shaped clamping plate 215, which can prevent the irregularly shaped clamping plate 215 from deflecting when it moves.

[0019] A specific application of this embodiment is as follows: In use, firstly, the pipe is respectively fitted onto the outside of the two X-shaped protrusions 111, then the motor 117 is started, so that the small spur gear 115 drives the large spur gear 114 to rotate counterclockwise, so that the large spur gear 114 drives the support arc plate 112 to slide from the inside of the X-shaped protrusions 111 outward through the cylindrical protrusion 113, and so that the outer surface of the support arc plate 112 is in contact with the inner surface of the pipe, and then the motor 117 is turned off. Next, the two X-shaped protrusions 111 that hold the tubes are moved to the top of the component horizontal plate 211. Then, the transmission round rods 116 on the left and right sides are connected together by plugging. Bolts are inserted into the interior of the connecting protrusions 122 to connect the two fixed square plates 121 to the component horizontal plate 211. Next, start the motor 216, so that the double screw 214 rotates counterclockwise and drives the irregular clamp 215 to move through the threads on the outer surface. The irregular clamp 215 on the front and back sides moves closer to each other along the irregular slide rail 221 through the irregular slider 222, and positions the tube from the front and back sides, positioning the tube at the top center of the component horizontal plate 211. Finally, the welding machine 232, model ZX7-200, is started. The welding machine 232 uses a power source to transmit current to the connection between the welding rod and the pipe, forming a high-temperature arc. The arc causes the welding rod and the pipe to partially melt and form a molten pool. As the welding rod moves, the molten pool cools and solidifies again, thus firmly welding the pipes together. Then, the motor 123 is started, causing the output end of the motor 123 to drive the transmission rod 116 to rotate. The rotation of the transmission rod 116 drives the support arc plate 112 to rotate, causing the support arc plate 112 to drive the pipe to rotate at a uniform speed. This allows the welding machine 232 to continuously weld the connection between the two pipes. Finally, the welded pipe is removed.
