[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] In existing technologies, welding operations mostly rely on manual operation or traditional simple equipment, which has many technical shortcomings: Firstly, traditional welding equipment lacks autonomous walking and adjustment capabilities, requiring manual adjustment of the welding position over a long period of time, which consumes manpower and time, resulting in a long preparation time for welding and seriously affecting the overall welding efficiency. Secondly, the welding process requires manual operation with a welding torch. Especially for the L-shaped connection sections of angle steel frames and angle steel strips, the angle of the welding torch needs to be adjusted repeatedly to achieve full welding, which is extremely labor-intensive. In addition, the harmful substances generated during the welding process can directly endanger the health of the operators, posing a significant safety hazard. Third, manual adjustment of the welding torch position has low precision, making it difficult to accurately control the welding path and easily resulting in welding dead angles. At the same time, the quality of manual welding is greatly affected by the operator's experience, and there are often problems such as incomplete welding and missed welding, resulting in insufficient strength of the angle steel connection. The overall welding process has poor stability and cannot meet the high standards of welding quality and efficiency required for angle steel tower structures.

[0021] Example: To solve these problems, the present invention provides, as follows Figures 1-18 The illustrated automatic welding device for angle steel towers includes a frame 1, an angle steel frame A, and angle steel bars C. The angle steel bars C are supported and moved by a hydraulic lifting platform vehicle D, and are welded to the angle steel frame A. The hydraulic lifting platform vehicle D can be manually operated or remotely controlled. The inner cavity of the frame 1 is equipped with multiple pulleys that are in contact with the surface of the angle steel frame A. The frame 1 is slidably connected to the angle steel frame A. The inner cavity of the frame 1 is equipped with a positioning mechanism 11 for fixing to the angle steel frame A. Multiple first welding points are rotatably connected to one end of the frame 1. Mechanism 2; The first welding mechanism 2 includes a rotating disk 28, and multiple first welding gun 26 clamping assemblies are provided on the side wall of the rotating disk 28. A weld positioning assembly 282 is provided at one end of the rotating disk 28. Multiple second welding mechanisms 3 are provided at the other end of the equipment frame 1, and a traveling mechanism 4 is provided at the top of the equipment frame 1. The equipment can be flexibly slid on the angle steel frame A and angle steel bar C by relying on pulleys. In conjunction with the traveling mechanism 4, the positioning mechanism 11, and the first welding mechanism 2 and the second welding mechanism 3, the continuous operation of welding position movement, fixing and welding can be realized, avoiding manual handling of equipment and improving welding efficiency.

[0022] The positioning mechanism 11 includes multiple first pneumatic rods 111 installed inside the equipment frame 1. The other end of each of the multiple first pneumatic rods 111 is connected to a positioning plate 112. One side of the positioning plate 112 abuts against the outer wall of the angle steel frame A, and the side wall of the positioning plate 112 is provided with an anti-slip groove 113. The positioning plate 112 can be pushed to abut against the angle steel frame A by the first pneumatic rods 111, and the anti-slip groove 113 on the positioning plate 112 can be used to prevent slippage, thereby achieving a firm fixation between the equipment and the angle steel frame A, preventing the equipment from shifting during welding, ensuring welding stability, eliminating the need for manual fixation, and reducing the amount of manual labor.

[0023] Multiple first welding mechanisms 2 and second welding mechanisms 3 each include a mounting frame 21. The mounting frame 21 of the first welding mechanism 2 is connected to the outer wall of the rotating disk 28, and the mounting frame 21 of the second welding mechanism 3 is connected to the outer wall of the equipment frame 1. Mounting plates 22 are slidably connected to both mounting frames 21. A first pneumatic push rod 23 is mounted on each mounting plate 22. One end of the first pneumatic push rod 23 is connected to an adjusting motor 24, and the output end of the adjusting motor 24 is connected to a clamping arm 25. A welding torch 26 is provided on the clamping port of the clamping arm 25. A second pneumatic push rod 27 is provided on the other end of the mounting frame 21. One end of the second pneumatic push rod 27 is connected to the mounting plate 22. The horizontal and vertical positions of the welding torch 26 can be adjusted by the first pneumatic push rod 23 and the second pneumatic push rod 27. The angle of the welding torch 26 can be adjusted in conjunction with the adjusting motor 24 to ensure that the welding torch 26 is precisely aligned with the welding position, avoiding manual adjustment of the welding torch 26, improving welding accuracy, and reducing problems such as incomplete welding and missed welding.

[0024] It should be noted that the first welding mechanism 2 and the second welding mechanism 3 have the same structure; this ensures the uniformity and coordination of the operation of the first welding mechanism 2 and the second welding mechanism 3, making it easy to achieve the main welding through the first welding mechanism 2 and the reinforcement welding through the second welding mechanism 3, thereby improving the overall strength of the welding of the angle steel frame A and the angle steel strip C, without the need for manual adaptation of different mechanisms, thus simplifying the operation process.

[0025] The outer wall of the rotating disk 28 is provided with a toothed ring groove 281; it can provide a transmission basis for the rotation of the rotating disk 28, and facilitate the drive component to drive the rotating disk 28 to rotate, thereby driving the first welding mechanism 2 to work around the angle steel frame A, meeting the full welding requirements of the L-shaped section and avoiding welding dead corners.

[0026] The inner cavity of the equipment frame 1 is equipped with a first drive motor 12. The power output end of the first drive motor 12 is connected to a gear 121 that meshes with the gear ring groove 281. The first drive motor 12 can drive the gear 121 to rotate, thereby driving the rotating disk 28 to drive the first welding mechanism 2 to rotate in a ring around the angle steel frame A and the angle steel bar C, realizing the circumferential welding of the L-shaped section. There is no need to manually rotate the welding torch 26, which improves the degree of automation and efficiency of welding and ensures the uniformity of welding.

[0027] The weld positioning assembly 282 includes a first electric telescopic rod 821 connected to one end of the equipment frame 1. One end of the first electric telescopic rod 821 is provided with a second pneumatic rod 822, and one end of the second pneumatic rod 822 is provided with a weld adjustment block 823. The bottom of the weld adjustment block 823 is conical, and the width of the weld adjustment block 823 is the weld width required for welding the angle steel. One end of the equipment frame 1 is provided with an arc-shaped groove 13 that matches the shape of the second pneumatic rod 822. The two angle steels to be welded are aligned and leave a gap... When there is a small gap, the first electric telescopic rod 821 can push the weld adjustment block 823 to squeeze at the gap of the angle steel, so that the angle steel to be welded can move to widen the gap of the angle steel to the required weld width. It is inserted between the cross-section of the angle steel frame A and the angle steel strip C to form a uniform gap, which is convenient for the molten welding wire to fill fully. This solves the problem of traditional manual welding that only connects the surface layer and has poor firmness. Moreover, there is no need to manually adjust the gap, saving labor time. The arc-shaped groove 13 can ensure the stability of the second pneumatic rod 822 and improve the positioning accuracy.

[0028] The traveling mechanism 4 includes a drive column 41 mounted on the top of the equipment frame 1. A second drive motor 42 is mounted on the drive column 41. One end of the second drive motor 42 is equipped with a lead screw slide 43. The bottom end of the lead screw slide 43 is equipped with two second electric telescopic rods 44. One end of the two second electric telescopic rods 44 is equipped with a protective frame 45. The protective frame 45 has a docking positioning opening. By fitting the steel frames to be docked into the docking positioning opening, the two steel frames can avoid docking misalignment during docking. The inner cavity of the protective frame 45 is equipped with two rubber rollers 46. The two rubber rollers 46 are connected to a traveling motor 47 through a rotating rod. The traveling motor 47 is mounted on the outer wall of the protective frame 45. The position of the rubber rollers 46 can be adjusted by adjusting the lead screw slide 43 and the second electric telescopic rods 44 through the second drive motor 42. In conjunction with the traveling motor 47, the rubber rollers 46 drive the equipment to move on the angle steel bar C, realizing autonomous adjustment of the welding position. After welding is completed, it can move to the next position by itself, avoiding manual handling of the equipment and greatly improving welding efficiency.

[0029] Working principle: First, the equipment needs to be installed on the steel frame before welding. The installation steps are as follows: Equipment installation phase and process (see below) Figures 10-16The steel frame A can be initially welded to the steel frame B by means of crossbar A1 and diagonal brace A2. The initial support is provided by the steel frame B being placed flat on the ground and connected by crossbar A1 and diagonal brace A2. It should be noted that the initial support needs to be completed by manual welding or pre-processing of the steel frame in advance. The subsequent welding operation is based on the initial support. The crossbar A1 and diagonal brace A2 can provide sufficient support. At this time, the equipment can be lifted by personnel using hydraulic lifting platform vehicle D or by multiple people and moved from the X end to the Z end to fit onto the steel frame A. This completes the initial installation and keeps the steel frame B and steel frame A fixed before the angle steel welding, providing a stable foundation for the equipment. Next, the second drive motor 42 in the walking mechanism 4 is started, which drives the lead screw slide 43 to adjust the horizontal position. Then, the second electric telescopic rod 44 is started, which pushes the protective frame 45 to one side of the angle steel bar C until the two rubber rollers 46 contact the surface of the angle steel bar C. At this time, the walking motor 47 is started, which drives the rubber rollers 46 to move on the angle steel bar C and moves the entire equipment on the angle steel frame A to one side of the angle steel bar C. This allows the equipment to move on the angle steel frame A by itself, moving to the position to be welded as needed. After welding, it can move to the next welding position by itself, which has high welding efficiency and avoids the impact of manual handling of the equipment on welding efficiency. It should be noted that during the above process, multiple first pneumatic rods 111 need to be activated to retract, so as to prevent the positioning plate 112 from contacting the angle steel frame A and the angle steel strip C. This, along with the multiple pulleys in the inner cavity of the equipment frame sliding on the angle steel strip C, ensures the flexibility of the equipment during movement. After the equipment moves to the designated position on the angle steel frame A, multiple first pneumatic rods 111 extend and push the positioning plate 112 to contact the surface of the angle steel strip C. The anti-slip grooves 113 on the positioning plate 112 prevent slippage after contact, ensuring the entire equipment is firmly fixed to the angle steel frame A. Next, the first electric telescopic rod 821 in the weld positioning assembly 282 is activated. The extension of the first electric telescopic rod 821 pushes the weld adjustment block 823 to insert into the contact point between the angle steel frame A and the angle steel strip C, creating a distance between the two angle steel frames A and the angle steel strip C that is the same as the diameter of the weld adjustment block 823. The main... The purpose is to create a gap between the two angle steel frames A and angle steel strip C sections. During the welding process, the welding rod of the welding torch 26 is inserted into the gap, and at the same time, the second pneumatic push rod 27 pushes the welding torch 26 to move slowly to the top. The molten welding wire can effectively fill the gap and firmly connect the two sections together. Compared with the traditional welding method, which can only weld the surface of the two angle steel frames A and angle steel strip C sections and has poor weld strength, this welding method can effectively solve the problem. Moreover, there is no need to manually adjust the distance of the welding gap during the welding process, saving the time spent on manual adjustment. Finally, the first pneumatic push rod 23 in the first welding mechanism 2 is activated, which pushes the welding torch 26 to move horizontally to ensure that the welding torch 26 is aligned with the welding position. Next, the second pneumatic push rod 27 is activated, which pushes the welding torch 26 to weld at the joint of the angle steel frame A and the angle steel strip C. After welding is completed, refer to... Figure 16 Then, the welding gun 26 of the second welding mechanism 3 is started to reinforce the supports (newly added A3 and A4) on the angle steel frame A; Since the connection end faces of angle steel frame A and angle steel strip C are L-shaped, the first drive motor 12 needs to be started during full welding. The gear 121 at the power output end of the first drive motor 12 drives the rotating disk 28 to rotate on the outer wall of the equipment frame 1, and drives the two first welding mechanisms 2 to circle around angle steel frame A and angle steel strip C. The first welding is fixed by spot welding. After the fixing is completed, the welding process is controlled by cooperating with the welding program calculation path preset by the equipment. The push rod is started to push the welding gun 26 to perform circumferential welding on the L-shaped section. Compared with traditional manual welding, the equipment has a high degree of automation. No manual operation is required during the entire welding process, which reduces the amount of manual welding labor. The efficiency of automated welding process is higher than that of manual welding, and it avoids the harm of harmful substances to the health of welders during the welding process. The advantage of automated welding is high welding stability. It will not have the problems of false welding or missing welding that occur in manual welding, thus ensuring the quality of welding of angle steel frame A and angle steel strip C.
