Description

Technical Field

[0001] This utility model belongs to the field of steel structure welding protection technology, and in particular relates to an intelligent welding device for steel structures of power plant boilers. Background Technology

[0002] Welding operations on steel structures of power plant boilers often involve the release of large amounts of fumes and harmful gases. These pollutants not only seriously threaten the health of the operators but also significantly interfere with welding precision and the quality of the working environment. Traditional welding equipment typically uses fixed fume extraction systems installed directly above the welding area to handle these fumes. However, this approach not only makes the entire system bulky and tall but can also severely hinder the flexible movement of the welding head if the fume extraction system is improperly positioned. Furthermore, the intense light and sparks generated during welding pose potential safety hazards and can easily lead to accidents.

[0003] Therefore, it is essential to invent an intelligent welding device for the steel structure of power plant boilers. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an intelligent welding device for the steel structure of a power plant boiler, comprising a steel structure welding frame, a downward-drawing smoke extraction seat, a smoke extraction device, a welding arm frame, a linear actuator, a sliding seat, and an intelligent welding arm. The steel structure welding frame and the downward-drawing smoke extraction seat are installed together, and the smoke extraction device is installed on the downward-drawing smoke extraction seat. A linear actuator is installed on the welding arm frame fixedly mounted above the downward-drawing smoke extraction seat, and an intelligent welding arm is installed on the sliding seat mounted on the linear actuator. The intelligent welding arm is located on one side of the steel structure welding frame and above the downward-drawing smoke extraction seat.

[0005] Preferably, the steel structure welding frame includes a conveyor frame, conveyor rollers, and shoulder plates. The conveyor frame is installed and connected to a bottom-drawing smoke extraction seat. A plurality of the conveyor rollers are rotatably installed on the upper inner side of the conveyor frame, and a plurality of the shoulder plates are fixedly installed on the outer side of the conveyor frame.

[0006] Preferably, a plurality of the conveying rollers are connected to a rack and pinion linkage mechanism built into the conveyor frame, wherein the input end of the rack and pinion linkage mechanism is fixed to the output end of the drive motor installed on the conveyor frame.

[0007] Preferably, a tilting shaft is rotatably mounted on the upper side of the conveyor frame, and either end of the tilting shaft is fixed to the output end of a drive component fixedly mounted on the conveyor frame. A welding view blocking plate is installed on the tilting shaft, and the welding view blocking plate is located around the shoulder plate.

[0008] Preferably, the down-draft smoking seat includes a smoking base, an electric linear guide rail, a smoking box, and a smoking duct unit. A welding arm frame is fixedly installed above the smoking base. The smoking base is installed together with a conveyor frame. A smoking box is installed on the electric linear guide rail fixedly installed inside the smoking base. The smoking box is slidably connected to the inside of the smoking base. At least two of the smoking duct units are installed inside the smoking box.

[0009] Preferably, the smoking base is equipped with a smoke extraction pipe cable chain that is connected to the smoking box, and the two ends of the smoke extraction pipe inside the smoke extraction pipe cable chain are respectively connected to the smoking box and the smoking device.

[0010] Preferably, the conveyor frame, the smoking base, and the smoking box are all provided with smoke extraction holes, which are opened through the surfaces of the three components perpendicular to the ground. The smoking box is used to draw external smoke into the smoking box through the smoke extraction holes opened through the three components.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention creatively adopts a downward-drawing fume extraction design, abandoning the traditional method of fixed upward-mounted fume extraction devices. This not only avoids a bulky and cumbersome device but also ensures that the fume extraction device does not interfere with the free movement of the welding head, thereby greatly improving the flexibility and efficiency of welding operations. Simultaneously, to address the strong light and sparks generated during welding, this invention cleverly incorporates a tilting shaft and a welding view blocking plate above the conveyor frame. These designs can quickly tilt into position, effectively blocking strong light and sparks, significantly reducing the risk of safety accidents and providing workers with a safer and more reliable working environment. Furthermore, through precise control of the downward-drawing fume extraction device, this invention can efficiently and in real time remove fumes and harmful gases generated during welding, significantly improving the air quality at the work site. This not only protects the health of workers but also reduces the interference of fumes on welding quality, thereby improving welding accuracy and overall quality. Attached Figure Description

[0021] As attached Figure 1 To be continued Figure 4 As shown:

[0022] This utility model provides an intelligent welding device for steel structures of power plant boilers, comprising a steel structure welding frame 1, a downward-drawing smoke extraction seat 2, a smoke extraction device 3, a welding arm frame 4, a linear actuator 5, a sliding seat 6, and an intelligent welding arm 7. The steel structure welding frame 1 and the downward-drawing smoke extraction seat 2 are installed together, and the smoke extraction device 3 is installed on the downward-drawing smoke extraction seat 2. The linear actuator 5 is installed on the welding arm frame 4, which is fixedly installed above the downward-drawing smoke extraction seat 2. The intelligent welding arm 7 is installed on the sliding seat 6, which is installed on the linear actuator 5. The intelligent welding arm 7 is located on one side of the steel structure welding frame 1 and above the downward-drawing smoke extraction seat 2.

[0023] Furthermore, the steel structure welding frame 1 includes a conveyor frame 11, conveyor rollers 12, and shoulder plates 13. The conveyor frame 11 is tightly installed together with the downward-drawing fume extraction seat 2, providing a stable support platform for welding operations. Several conveyor rollers 12 are rotatably mounted on the upper inner side of the conveyor frame 11. These conveyor rollers 12 are connected to the built-in mounting structure of the conveyor frame 11 via a rack and pinion linkage mechanism. The input end of the rack and pinion linkage mechanism is fixedly connected to the output end of a drive motor mounted on the conveyor frame 11, realizing automated conveying of steel structure components on the conveyor frame 11. Several shoulder plates 13 are also fixedly installed on the outer side of the conveyor frame 11. These shoulder plates 13 provide additional support for the welding process, ensuring the stability and accuracy of the welding operation.

[0024] Furthermore, to further improve the safety and reliability of welding operations, a tilting shaft 14 is rotatably mounted on one side of the upper part of the conveyor frame 11. One end of the tilting shaft 14 is fixed to the output end of a drive component 16 fixedly mounted on the conveyor frame 11. Driven by the drive component 16, the tilting shaft 14 can rotate the welding view blocking plate 15 mounted on it. The welding view blocking plate 15 is located around the shoulder plate 13 and can quickly rotate into position when necessary, effectively blocking the strong light and sparks generated during welding, greatly reducing the risk of safety accidents.

[0025] Furthermore, the downward-drawing fumigation seat 2 includes a fumigation base 21, an electric linear guide rail 22, a fumigation box 23, and a fumigation duct unit 24. A welding arm frame 4 is fixedly installed above the fumigation base 21. The fumigation base 21 is installed together with the conveyor frame 11, providing a stable mounting platform for the fumigation box 23. Inside the fumigation base 21, the electric linear guide rail 22 is fixedly installed, and the fumigation box 23 slides within the fumigation base 21 via the electric linear guide rail 22. At least two fumigation duct units 24 are installed inside the fumigation box 23, which can efficiently remove fumes and harmful gases generated during the welding process.

[0026] Furthermore, to ensure a smooth connection between the smoking box 23 and the smoking device 3, a smoking pipe drag chain 25 is also installed inside the smoking base 21. The two ends of the smoking pipe inside the smoking pipe drag chain 25 are connected to the smoking box 23 and the smoking device 3 respectively, realizing the real-time emission of smoke and harmful gases.

[0027] Furthermore, to further improve smoke extraction efficiency, smoke extraction holes 26 are provided on the conveyor frame 11, the smoke extraction base 21, and the smoke extraction box 23. These smoke extraction holes 26 are formed through the surfaces of the three components perpendicular to the ground, allowing the smoke extraction box 23 to efficiently draw in external fumes through these holes 26 and then discharge them through the smoke extraction device 3. This design not only improves smoke extraction efficiency but also ensures air quality at the welding work site.

[0028] The working principle is as follows: First, the steel structure components are placed on the conveyor frame 11 of the steel structure welding machine frame 1. The conveyor frame 11, through a design where several conveyor rollers 12 are rotatably mounted on its inner upper side, and these conveyor rollers 12 are connected to a rack and pinion linkage mechanism built into the conveyor frame 11, achieves automated conveying of the steel structure components on the conveyor frame 11. The input end of the rack and pinion linkage mechanism is fixedly connected to the output end of the drive motor mounted on the conveyor frame 11. When the drive motor starts, it drives the rack and pinion linkage mechanism, which in turn drives the conveyor rollers 12 to rotate, smoothly conveying the steel structure components to the welding position.

[0029] Then, when the steel structure component below is transported to the welding position, the linear actuator 5 on the welding arm frame 4 begins to operate. The linear actuator 5 drives the intelligent welding arm 7 to move precisely via its mounted sliding seat 6. The intelligent welding arm 7 is located on one side of the steel structure welding frame 1 and above the downward-extracting fume extractor 2. It can automatically weld the steel structure component according to the preset welding path and parameters.

[0030] During the welding process, the downward-drawing fume extraction stand 2 begins to play its crucial role. The fume extraction base 21 is installed together with the conveyor frame 11, providing a stable mounting platform for the fume extraction box 23. At least two fume extraction duct units 24 installed inside the fume extraction box 23 begin operating, efficiently removing fumes and harmful gases generated during welding through fume extraction holes 26. These extraction holes 26 are formed on the perpendicular surfaces of the conveyor frame 11, the fume extraction base 21, and the fume extraction box 23, ensuring that the fume extraction box 23 can efficiently draw in external fumes.

[0031] Meanwhile, to ensure a smooth connection between the smoking box 23 and the smoking device 3, a smoke extraction pipe chain 25 is also installed inside the smoking base 21. The two ends of the smoke extraction pipe inside the chain 25 are connected to the smoking box 23 and the smoking device 3 respectively, enabling real-time emission of smoke and harmful gases. When the smoke and harmful gases in the smoking box 23 accumulate to a certain level, they are transported to the smoking device 3 through the smoke extraction pipe for further processing and emission.

[0032] In addition, to improve the safety and reliability of welding operations, a tilting shaft 14 is rotatably mounted on one side of the upper part of the conveyor frame 11. When strong light and sparks are generated during welding, the drive component 16 drives the tilting shaft 14 to tilt, causing the welding view blocking plate 15 mounted on it to quickly tilt into place. The welding view blocking plate 15 is located around the shoulder plate 13 and can effectively block the strong light and sparks generated during welding, greatly reducing the risk of safety accidents.

[0033] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
