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

[0020] See Figures 1 to 11 As shown, a seamless welding device for power steel pipe poles includes a C-shaped mounting frame 1, a positioning mechanism 2, an inner support mechanism 3, and a welding mechanism 4. The C-shaped mounting frame 1 is equipped with a mounting ring 11. Two sets of positioning mechanisms 2 are equidistantly arranged inside the mounting ring 11. The positioning mechanisms 2 enable the steel pipe to be coaxially positioned with the mounting ring 11 and to move along the axis of the mounting ring 11. Each positioning mechanism 2 includes multiple first telescopic rods 21 radially arranged along the axis of the mounting ring 11. Each first telescopic rod 21 extends into the mounting ring 11, and one end is rotatably equipped with a first auxiliary roller 23 for adhering to the outer wall of the steel pipe via a C-shaped plate 22. A connecting plate 12 is radially arranged on the inner wall of the top of the mounting ring 11, and the connecting plate 12 is located away from the mounting ring 11. One end of the inner wall of the mounting ring 11 is provided with a mounting post 13 coaxial with the mounting ring 11. The mounting post 13 is provided with an inner support mechanism 3 that can support the inside of the steel pipe when it moves. One end of the mounting post 13 is provided with a plurality of guide grooves 131 radially along the axial direction. The inner support mechanism 3 includes a plurality of sliding blocks 31 slidably disposed in the corresponding guide grooves 131. Each sliding block 31 is provided with a connecting strip 32 extending radially toward the inner wall of the mounting ring 11. A second auxiliary roller 33 is rotatably disposed at the end of each connecting strip 32 away from the sliding block 31. The second auxiliary roller 33 and the corresponding first auxiliary roller 23 are in the same vertical plane. The welding mechanism 4 is disposed on the connecting plate 12 and is used to weld the positioning weld.

[0021] To facilitate better longitudinal seam welding of the steel pipes, two sets of positioning mechanisms 2 are installed on the mounting ring 11. Each positioning mechanism 2 includes a first telescopic rod 21 circumferentially arranged on the inner wall of the mounting ring 11. Multiple first telescopic rods 21 move synchronously toward the steel pipe, thereby curling steel pipes of different specifications into a circular shape and ensuring that the steel pipe is coaxially aligned with the mounting ring 11. The two sets of positioning mechanisms 2 also prevent deformation of the steel pipe due to its excessive length during the curling process. During the curling process, the connecting plate 12 is positioned between the weld seams of the steel pipe, thus achieving… For positioning the steel pipes on both sides of the weld, the mounting post 13 at the end of the connecting plate 12 is located at the center inside the steel pipe. Multiple guide grooves 131 are radially provided at the end of the mounting post 13. Through the synchronous movement of multiple sliding blocks 31, multiple second auxiliary rollers 33 can fit against the inner wall of the steel pipe, thereby supporting the inner wall of the steel pipe. Secondly, the second auxiliary rollers 33 and the corresponding first auxiliary rollers 23 are located in the same vertical plane. The first auxiliary rollers 23 and the corresponding second auxiliary rollers 33 cooperate with each other to perform secondary positioning of the steel pipe, avoid deformation during the movement of the steel pipe, and improve the welding quality.

[0022] See Figures 3 to 6 As shown, the inner support mechanism 3 also includes a synchronous shaft 34 and a first threaded rod 35; a mounting hole 132 is provided at the center of the mounting column 13, the synchronous shaft 34 is rotatably disposed inside the mounting hole 132, a contact hole 133 is also provided at the center of one end of the mounting column 13 near the guide groove 131, a first bevel gear 341 is provided at one end of the synchronous shaft 34 extending into the contact hole 133, a first threaded rod 35 is rotatably disposed in each guide groove 131, a sliding block 31 is threadedly connected to the corresponding first threaded rod 35, and a second bevel gear 351 is provided at one end of each first threaded rod 35 near the mounting hole 132 extending into the contact hole 133, and the first bevel gear 341 meshes with the corresponding plurality of second bevel gears 351.

[0023] The mounting hole 132 is also equipped with a drive motor for driving the synchronous shaft 34 to rotate. The drive motor drives the synchronous shaft 34 to rotate, and the first bevel gear 341 at the end of the synchronous shaft 34 can rotate with the rotation of the synchronous shaft 34. The first bevel gear 341 meshes with multiple second bevel gears 351, thereby driving the multiple second bevel gears 351 to rotate synchronously. With the synchronous rotation of the multiple second bevel gears 351, multiple first threaded rods 35 can drive multiple sliding blocks 31 connected to them to move synchronously, so that multiple second auxiliary rollers 33 connected by connecting strips 32 can fit against the inner wall of the steel pipe. The second auxiliary rollers 33 can correspond one-to-one with the corresponding first auxiliary roller 23 of one of the positioning mechanisms 2, so that the inner and outer walls of the steel pipe can be synchronously supported during the movement of the steel pipe, avoiding deformation of the steel pipe during the movement, which would cause deviation of the weld position and affect the welding quality.

[0024] See Figure 2 and Figure 4 As shown, the welding mechanism 4 includes a second telescopic rod 41 and a welding torch 42; the connecting plate 12 is connected to the inner wall of the mounting ring 11 through the connecting column 121, the second telescopic rod 41 is vertically mounted on the connecting column 121, the connecting plate 12 is provided with a strip-shaped through groove 122 for avoiding the second telescopic rod 41, and the end of the second telescopic rod 41 is provided with a welding torch 42 for welding the weld.

[0025] The welding torch 42 is moved by the second telescopic rod 41, so that the welding torch 42 can be brought closer to the weld seam according to the diameter of the steel pipe of different specifications, so as to carry out the welding work.

[0026] See Figures 5 to 11 As shown, a bonding mechanism 5 is also provided in the strip groove 122 to bring the steel pipes on both sides of the weld closer together; the bonding mechanism 5 includes a V-shaped plate 51, a rotating shaft 52, a servo motor 53, and a threaded sleeve 54; there are two V-shaped plates 51, and the two bonding plates are slidably arranged in the strip groove 122 in a horizontal state. Each V-shaped plate 51 has a rotating hole 511 in the middle position. The rotating shaft 52 is rotatably arranged in the rotating hole 511 of the lower bonding plate. The threaded sleeve 54 is coaxially rotatably arranged on the upper bonding plate. A second threaded rod is coaxially arranged on the top of the rotating shaft 52. The second threaded rod passes through the corresponding rotating hole 511 and is threadedly connected to the threaded sleeve 54. Multiple gear teeth 541 are arranged circumferentially on the outer wall of the threaded sleeve 54. The servo motor 53 is arranged on the upper bonding plate. A drive gear 531 is arranged on the motor shaft of the servo motor 53. The drive gear 531 meshes with the corresponding gear teeth 541.

[0027] To further limit the movement of the steel pipes on both sides of the weld and prevent deformation, a servo motor 53 is installed. In the initial state, two V-shaped plates 51 are arranged sequentially, with the two V-shaped plates 51 as far apart as possible to provide space for the steel pipe to enter. After the steel pipe enters, the servo motor 53 drives the drive gear 531 to rotate. The drive gear 531 drives the threaded sleeve 54 to rotate through the gear teeth 541. As the threaded sleeve 54 rotates, the second threaded rod connected to it rotates. Since the threaded sleeve 54 is rotatably connected to the upper V-shaped plate 51 and the rotating shaft 52 is rotatably connected to the lower V-shaped plate 51, the two V-shaped plates 51 can move closer to each other. Depending on the position of the weld, the two sides of the V-shaped plates 51 can be close to the inner and outer walls of the steel pipe, so that the steel pipes on both sides of the weld are tightly attached to the outer wall of the connecting plate 12, thereby adjusting the position of the steel pipes on both sides of the weld and ensuring the quality of the weld.

[0028] See Figure 8 As shown, the upper V-shaped plate 51 is also provided with a clearance hole 512 for avoiding the welding torch 42.

[0029] By providing clearance holes 512 on the V-shaped plate 51, the welding torch 42 can perform welding in the area between the two V-shaped plates 51. This improves the welding quality with the assistance of the two V-shaped plates 51 and prevents the weld from shifting out of the positioning area of ​​the V-shaped plate 51, thus avoiding secondary displacement of the steel pipes on both sides of the weld.

[0030] See Figures 5 to 11 As shown, two sliding grooves 513 are provided on both sides of the facing ends of the two V-shaped plates 51. The length direction of the sliding grooves 513 is the same as that of the V-shaped plates 51. A bidirectional lead screw 55 is rotatably installed in each sliding groove 513. A transverse groove 514 is also provided on both sides of the facing ends of the two V-shaped plates 51. A transverse roller 56 is rotatably installed in each transverse groove 514. A drive gear 561 is coaxially installed on one side of the transverse roller 56. A driven gear is provided at one end of each bidirectional lead screw 55 that extends into the transverse groove 514. The driven gear is connected to the corresponding drive gear. Gear 561 meshes; each bidirectional lead screw 55 is threadedly connected to a moving block 57, the moving block 57 is slidably disposed in a sliding groove 513, each sliding groove 513 is also provided with a moving column 58, the center of the moving column 58 is provided with a receiving cavity 581 for the moving block 57 to move, the moving column 58 can move back and forth along the length direction of the moving column 58 while the moving block 57 moves; each moving column 58 is provided with a moving plate 582 at the end away from the sliding groove 513, and each moving plate 582 is provided with a rubber pad 583.

[0031] To further bring the steel pipes on both sides of the weld closer together, thereby ensuring welding quality, as the two V-shaped plates 51 approach each other, the moving plate 582 contacts the inner and outer walls of the steel pipe through the rubber pad 583. At this time, the transverse roller 56 contacts the inner and outer walls of the steel pipe. As the steel pipe moves, the transverse roller 56 rotates, and through the meshing of the drive gear 561 and the driven wheel 551, the two double-acting screws 55 rotate. As the two double-acting screws 55 rotate, the moving block 57 connected to the double-acting screws 55 rotates. As the moving block 57 rotates, the moving columns 58 located on both sides of the V-shaped plate 51 approach each other. During the movement of the moving columns 58... The moving column 58 moves closer to the inner and outer walls of the steel pipe. Under the friction of the rubber pad 583, the moving plate 582 applies a thrust towards the weld seam to the inner and outer walls of the steel pipe, thereby further positioning the steel pipes on both sides of the weld seam. Secondly, as the double-acting screw 55 rotates, when the moving columns 58 located on both sides of the V-shaped plate 51 move away from each other, the moving columns 58 can move away from the inner and outer walls of the steel pipe, causing the rubber pad 583 to separate from the steel pipe, thus preventing the weld seam from enlarging. Under the action of the double-acting screw 55, as the steel pipe moves, pressure can be continuously applied to the steel pipes on both sides of the weld seam, thereby ensuring the stability of the weld seam.

[0032] See Figures 5 to 11 As shown, each sliding groove 513 has an isosceles triangular guide groove 515 on both sides of its inner wall, and each moving column 58 has a guide column 584 on both sides that cooperates with the guide groove 515. The guide column 584 is slidably disposed in the corresponding guide groove 515.

[0033] By providing a guide groove 515, the moving column 58 can slide up and down along the trajectory of the guide groove 515 as it moves with the moving block 57. During this process, the corresponding moving plate 582 can apply pressure to the steel pipe in the direction of the weld as the moving column 58 moves. In order to apply pressure to the steel pipe more effectively and continuously, the moving trajectories of the two moving columns 58 on the same side of the V-shaped plate 51 are not synchronized, so as to ensure that the moving plate 582 is always in contact with the steel pipe during the steel pipe processing, thereby ensuring the welding quality.

[0034] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
