Description

Technical Field

[0001] This utility model relates to the field of steel structure welding technology, specifically a high-altitude steel structure welding robot. Background Technology

[0002] Steel structures are one of the most commonly used structural forms in modern construction engineering. Due to their lightweight, high strength, earthquake resistance, and durability, they are widely used in bridges, factories, high-rise buildings, and stadiums. Among the connection methods for steel structures, welding significantly improves the integrity and rigidity of the structure due to its ability to achieve seamless connections; therefore, it has been widely adopted. However, welding work is often carried out at heights, requiring welders to work on frames tens or even hundreds of meters high, increasing safety risks and posing significant challenges. Consequently, high-altitude welding equipment has emerged.

[0003] For example, a Chinese patent discloses a high-altitude welding device for steel structures (authorization announcement number CN212286460U). This patented technology is equipped with a lifting mechanism that can adjust the height of the welding parts according to the height of the welding point, and can weld objects of different heights, making it convenient to use; however, its welding position is limited, and it cannot weld multiple positions of the steel structure, so its practicality is not high.

The aerial work platform 1, the operating platform unit 3 and the steel structure product 4 are all located on the ground. The aerial work platform 1 and the welding mechanism 2 are controlled by the operating platform unit 3, and the steel structure product 4 is welded at high altitude by the welding mechanism 2.

[0022] exist Figure 2 and Figure 3 In this assembly, the welding mechanism 2 includes a rotating component 22 mounted on the upper part of the aerial work platform 1. A welding box 21 is mounted on one side of the rotating component 22. A welding machine 26 is installed inside the welding box 21, and heat dissipation windows 28 are installed on both sides of the welding box 21 to dissipate the heat generated by the welding machine 26. A traveling component 27 is mounted inside the welding box 21 near the upper part of the welding machine 26. A robotic arm 23 is mounted on the upper part of the traveling component 27. A welding torch 25 is mounted on one side of the robotic arm 23, and a CCD camera 24 is mounted on the outer side of the robotic arm 23 near the welding torch 25. After the aerial work platform 1 moves the welding mechanism 2 to the corresponding position, the CCD camera 24 performs video monitoring of the steel structure product 4 to accurately observe the position to be welded. The rotating component 22 drives the welding box 21 to rotate at a certain angle. The traveling component 27 drives the robotic arm 23 to move linearly. The robotic arm 23 can move the welding torch 25 to the position to be welded, thus welding the steel structure product 4.

[0023] exist Figure 3 and Figure 4In the process, the walking component 27 includes a lead screw frame 274, one end of which is equipped with a lead screw motor 271. The output end of the lead screw motor 271 is fixedly connected to a ball screw 273, and a nut assembly 272 is installed on the ball screw 273.

The lead screw frame 274 is fixedly installed on the upper end of the inner side of the welding box 21. The lead screw motor 271 drives the ball screw 273 to rotate, causing the nut assembly 272 to move linearly, thereby driving the robotic arm 23 to move linearly, thus realizing the fine adjustment of the position of the robotic arm 23.

[0024] exist Figure 2 , Figure 3 and Figure 5 In the process, the rotating assembly 22 includes a U-shaped block 221 mounted on the upper end of the aerial work platform 1. A connecting rod 224 is fixedly connected to one end of the U-shaped block 221.

The upper end of the mobile operating table 31 is equipped with an operating handle 33, a gas tank 34 and a monitoring display 35. The monitoring display 35 can display the video image captured in real time by the CCD camera 24, thereby realizing precise welding of the steel structure product 4. The gas tank 34 can provide gas protection to the welding torch 25 during welding, improving the weld quality. The operating handle 33 can control the rotation of the rotating component 22 and the translation of the walking component 27. After the welding route is imported through the teach-through device 32, the robotic arm 23 automatically drives the welding torch 25 to move and weld the weld.

[0026] The working principle of this utility model is as follows: First, the aerial work platform 1 is moved to the ground 5 near the steel structure product 4. Then, the aerial work platform 1 drives the welding mechanism 2 to be lifted and moved to the position to be welded near the steel structure product 4.

[0027] Next, the rotating component 22 drives the welding box 21 to rotate at a certain angle; the walking component 27 drives the robotic arm 23 to make linear motion, and the position of the robotic arm 23 is finely adjusted so that the welding torch 25 on the robotic arm 23 is close to the welding position; then, after the welding route is imported by the teaching aid 32, the robotic arm 23 automatically drives the welding torch 25 to move at multiple angles to weld the weld, realizing high-altitude welding, which has high safety and ensures welding quality.
