Description

Technical Field

[0001] This utility model relates to the technical field of iron tower production, and in particular to an iron tower frame joint welding device. Background Technology

[0002] Cylindrical iron towers are generally welded from curved steel plates, which are formed by rolling and bending steel plates to meet the required curvature. The thicker lower part of the cylindrical iron tower is usually made of two or more curved steel plates welded together, while the thinner upper part is made of a single curved steel plate welded together.

[0003] Chinese utility model patent CN216298341U discloses a jointing machine for cylindrical iron towers. This machine adjusts the position of the slide table according to the size of the curved steel plate of the cylindrical iron tower. The curved surface of one steel plate is placed on two driving wheels and two driven wheels. The drive mechanism is activated, causing the two driving wheels to rotate. The curved steel plate rotates slowly under the drive of the two driving wheels, making its two edges horizontal. Then, another curved steel plate is placed upside down on top of the first curved steel plate, so that the two edges of the two steel plates contact each other. At this time, two alignment mechanisms are activated, moving and positioning the upper curved steel plate. The plates are then pressed together to align their edges. Workers use a welding machine to weld several joints at the sides of the two curved steel plates for temporary splicing. The drive mechanism is then restarted, and the two temporarily spliced ​​curved steel plates are slowly rotated via the drive wheel, bringing the weld seam directly above the device. The welding torch is adjusted, and the welding mechanism is started for automatic welding. After welding, the two curved steel plates are rotated again to weld another weld seam. Once both weld seams are completed, the two alignment mechanisms are opened to remove a section of the cylindrical iron tower. This process achieves automatic alignment and positioning of the curved steel plate joints, combined splicing and shaping, and automatic welding, improving work efficiency.

[0004] The aforementioned seam welding machine is convenient for welding two steel plates together, but it is not convenient for welding the seam of a curved steel plate. It also cannot adjust the clamping and alignment force according to the weld width at different parts of the seam, thus failing to make the seam width uniform and hindering the improvement of welding quality. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a steel tower frame joint welding device that can perform joint welding on an arc-shaped steel plate and adjust the clamping force of each part to make the joint uniform and improve the welding quality.

[0006] This utility model discloses a welding device for the joint of a steel tower frame, comprising a base plate, multiple rollers, and a welding torch. The multiple rollers are rotatably mounted on the base plate. It also includes multiple clamping mechanisms. The rollers are arranged in a V-shape and roll to support an arc-shaped steel plate. The welding torch is mounted on the base plate via a bracket assembly. The clamping mechanisms are evenly mounted on the base plate. Each clamping mechanism includes a mounting plate, a crossbar, a clamp seat, a clamping band, and a push cylinder. The mounting plate is vertically mounted on the base plate, the outer end of the crossbar is horizontally mounted on the mounting plate, the clamp seat is mounted on the inner end of the crossbar, and the clamp seat has a horizontal slot. One end of the clamping band is connected to the outer wall of the clamp seat, and the other end of the clamping band passes around the arc-shaped steel plate and through the slot of the clamp seat. The fixed end of the push cylinder is mounted on the clamp seat, and the piston rod of the push cylinder is connected to the other end of the clamping band via a connector. During operation, the arc-shaped steel plate is placed on the multiple rollers, and the arc-shaped steel plate... With the seam facing upwards, the ends of multiple clamping bands pass through the slots of the clamping seat after wrapping around the bottom of the arc-shaped steel plate. The piston rods of multiple push cylinders are connected to the ends of the clamping bands through connectors. The piston rods of the multiple push cylinders extend and tighten the clamping bands, thereby clamping the arc-shaped steel plate tightly. This brings the seam of the arc-shaped steel plate closer together. The extension of the piston rods of the multiple push cylinders is adjusted according to the weld width at different parts of the seam, so that the overall width of the seam is uniform. The support assembly is adjusted so that the welding torch moves along the seam of the arc-shaped steel plate for spot welding and positioning. After spot welding and positioning, the multiple clamping bands are loosened and removed, allowing the welding torch to fully weld the seam of the arc-shaped steel plate. Compared with the existing technology, this method can facilitate the seam welding of an arc-shaped steel plate and can adjust the clamping force according to the width of each part of the seam, thereby making the seam uniform and improving the welding quality.

[0007] Preferably, it also includes multiple push plates and multiple push cylinders II, multiple crossbars are slidably connected to multiple mounting plates, push plates are installed on the outer ends of multiple crossbars, the fixed ends of multiple push cylinders II are respectively installed on multiple push plates, and the piston rods of multiple push cylinders II are respectively connected to multiple mounting plates; the piston rods of multiple push cylinders II extend or shorten, respectively, driving multiple crossbars to move along multiple mounting plates through multiple push plates, adjusting the position of multiple clamps, thereby adapting to arc-shaped steel plates of different diameters, with good versatility, and after multiple push cylinders II retract, multiple clamps and multiple push cylinders I avoid the welding torch, improving welding efficiency.

[0008] Preferably, the support assembly includes a slide rail, a rack, a slider, a motor, and a gear. The slide rail is mounted on the base plate via a column, the rack is mounted on the slide rail, the slider is slidably mounted on the slide rail, the motor is mounted on the slider, and the output shaft of the motor is concentrically mounted with a gear that meshes with the rack. The welding torch is mounted on the slider. The motor drives the gear to rotate, and the gear meshes with the rack, thereby moving the slider along the slide rail. The slider then moves the welding torch along the joint, thus enabling the welding torch to automatically weld the joint, resulting in high work efficiency.

[0009] Preferably, it also includes a welding torch chuck, one end of which is rotatably mounted on the slider, and the other end of which is rotatably mounted on a chuck, with the welding torch clamped on the chuck of the welding torch chuck; by adjusting the angle of the welding torch chuck and the angle of the chuck thereon, the angle and position of the welding torch are adjusted so that the welding torch can be aligned with the joint of the curved steel plate, thereby improving the welding quality.

[0010] Preferably, the column includes an upright and an upper connecting rod. The upright is vertically installed on the base plate, one end of the upper connecting rod is hinged to the upper end of the upright, and the other end of the upper connecting rod is connected to the slide rail. The height and position of the slide rail can be adjusted by adjusting the pitch angle of the upper connecting rod, which is suitable for curved steel plates of different diameters and has good versatility.

[0011] Preferably, it also includes multiple wheel frames, multiple motors, multiple driving pulleys, multiple driven pulleys, and multiple transmission belts. The surfaces of all the rollers are decorated with helical patterns, and the threads of two oppositely arranged rollers rotate in opposite directions.

The rollers are mounted on multiple driven wheels; multiple wheel frames support multiple rollers arranged in a V-shape; multiple motors drive multiple driving wheels to rotate; the driving wheels drive multiple transmission belts to rotate multiple driven wheels and multiple rollers. When the multiple rollers on the left and right rotate in opposite directions, the friction of the multiple rollers drives the arc-shaped steel plate to move back and forth; when the multiple rollers on the left and right rotate in the same direction, the friction of the multiple rollers drives the arc-shaped steel plate to rotate, thus realizing the adjustment of the angle and position of the arc-shaped steel plate, which is practical.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: During operation, the arc-shaped steel plate is placed on multiple rollers with the seam of the arc-shaped steel plate facing upwards. The ends of multiple clamping bands pass around the bottom of the arc-shaped steel plate and through the slots of the clamping seat. The piston rods of multiple push cylinders are connected to the ends of the multiple clamping bands through connecting parts.

The extension of the piston rods of multiple push cylinders is adjusted according to the weld width at different parts of the seam, so that the overall width of the seam is uniform. The support assembly is adjusted so that the welding torch moves along the seam of the arc-shaped steel plate for spot welding and positioning. After spot welding and positioning, the multiple clamping bands are loosened and removed, so that the welding torch can fully weld the seam of the arc-shaped steel plate. Compared with the prior art, it is more convenient to weld the seam of an arc-shaped steel plate and can adjust the clamping force according to the width of each part of the seam, so that the overall seam is uniform and the welding quality is improved.
