The embodiment discloses a using method of the flange welding equipment for tower tube machining, and further includes the following welding method: S1, first, the tower tube 9 and the tower tube flange 901 to be welded are placed on the surfaces of the first horizontal shaft 3 and the second horizontal shaft 4 through a crane, then the first air cylinders 5 on the two sides are started, the tower tube 9 and the tower tube flange 901 are pushed and moved along the surfaces of the first horizontal shaft 3 and the second horizontal shaft 4, until the seams of the tower tube 9 and the tower tube flange 901 are below the electric welding machine 15, and the preparation work is completed. S2, then start the motor 2. After the motor 2 is started, the inner gear ring 22 starts to rotate. When the inner gear ring 22 rotates, it causes the fixed frame 13 to tilt along the outer wall of the first ball 12. At this time, the discharge pipe 16 and the ball 19 hit the joint between the tower flange 901 and the tower 9. As the inner gear ring 22 rotates, the paste solder paste in the fixed frame 13 can be squeezed out of the discharge pipe 16 in the joint in a curved manner. The curved extrusion can make the solder paste more evenly distributed. At this time, the two arc scrapers 49 repeatedly move closer to each other and then away from each other, causing the bent solder paste to be scraped and gathered toward the central joint, so that the solder paste is more evenly distributed at various positions of the annular weld. S3, then the motor 2 is rotated in the reverse direction. At this time, the inner gear ring 22 rotates in the reverse direction, causing the fixed frame 13 to tilt along the outer wall of the first ball 12 in the opposite direction of S2, causing the electric welder 15 to contact the weld. At this time, the electric welder 15 is started and welds the weld with a wavy welding curve, which just corresponds to the extrusion path of the solder paste. The wavy welding curve cooperates with the rotating weld, which can better weld the weld and evenly heat the entire weld. S4. After the welding is completed, the first cylinder 5 on one side is started to push out the tower 9 and the tower flange 901 connected after the welding to complete the welding process.

[0020] In this embodiment, the tower is the tower of wind power generation, which mainly plays a supporting role in the wind turbine generator set and absorbs the vibration of the set. During the processing of the tower, the flange that plays a docking role needs to be welded to the end of the tower, so a tower welding device is required to perform girth welding. During the use of the existing tower flange welding device on the market, after the flange and the end of the tower are butted together, circumferential welding is usually required. However, due to the large volume of the tower, the weld is large after the flange is butted together. Before the welding process, welding machine is required to be sprinkled or solder paste is squeezed into the weld to achieve the best welding effect. However, due to the large weld, uneven addition of solder paste to the circumferential seam is likely to occur during the process of adding solder paste, resulting in a decrease in welding quality. In order to avoid the above situation, when using the tower welding device, first, the tower 9 and tower flange 901 to be welded are placed on the surface of the first horizontal axis 3 and the second horizontal axis 4 by a crane, and then the first cylinders 5 on both sides are started to push and move the tower 9 and the tower flange 901 along the surface of the first horizontal axis 3 and the second horizontal axis 4 until the joint of the tower 9 and the tower flange 901 is under the electric welder 15, and the preparation work is completed; Subsequently start the motor 2, the motor 2 starts, with the output gear 21 rotates, gear 21 rotates through the meshing relationship with the inner tooth ring 22 rotates, inner tooth ring 22 rotates, the outer wall of the second ring groove 26 and the first ring groove 25 synchronous rotation is opened in the inner tooth ring 22, at this time in the second ring groove 26 of the second guide rod 37 will be with the second ring groove 26 rotation, finally into the arc groove 27, and because of the path of the arc groove 27, at this time the second guide rod 37 will be stressed, the second guide rod 37 stressed with one end of the discharge pipe 16 downward stressed, the discharge pipe 16 at this time with a side of the fixed frame 13 downward stressed, at this time the fixed frame 13 will rotate along the outer wall of the first ball 12 to tilt towards the end of the discharge pipe 16, tilt to make the discharge pipe 16 with the end of the ball 19 to resist the contact between the tower drum 9 and the tower drum flange 901, the contact to make the ball 19 stressed pressing movement frame 18, movement frame 18 stressed compression second spring 17 and displacement, at this time the movement frame 18 unblock the lower end of the discharge pipe 16, and because the outer contour of the movement frame 18 is less than the inner wall contour of the discharge pipe 16, at this time start the second cylinder 20, the second cylinder 20 output end elongation with the push plate 211 down continuously compression solder paste in the second torsional spring 34, see attached Figure 9 , make the solder paste from the port of the discharge pipe 16 uniform speed extrusion, at this time the solder paste can be along the ring gap extrusion; With the continuous rotation of the inner tooth ring 22, the first protrusions 23 and the semispherical grooves 24 on the outer wall of the inner tooth ring 22 also rotate synchronously in a circle. It should be noted that the fixed frame 13 in the initial state is in a state where the first guide rod 36 with the end portion enters the semispherical groove 24 under the action of the two first springs 14. With the rotation of the inner tooth ring 22, the first guide rod 36 will slide along the semispherical groove 24 to the surface of the inner tooth ring 22. At this time, the end portion of the first guide rod 36 protrudes outside the semispherical groove 24, so at this time the first guide rod 36 will rotate the side of the fixed frame 13 away from the horizontal plane direction of the inner tooth ring 22. With the first guide rod 36 sliding along the surface of the inner tooth ring 22 and abutting against the first protrusion 23, the abutment causes the first guide rod 36 to rotate the side of the fixed frame 13 along the first rolling ball 12 away from the horizontal plane direction of the inner tooth ring 22. When the inner tooth ring 22 continues to rotate and causes the first guide rod 36 to slide into the semispherical groove 24, at this time the two first springs 14 that are bent due to the above rotation are reset, causing the fixed frame 13 to enter the semispherical groove 24 with the first guide rod 36. At this time, the fixed frame 13 rotates along the first rolling ball 12 to the initial position. Since the first protrusions 23 and the semispherical grooves 24 are uniformly distributed, the fixed frame 13 will rotate along the first rolling ball 12 to reciprocate in the horizontal direction clockwise and counterclockwise. At this time, the discharge pipe 16 extrudes the solder paste to the annular gap in a wave-shaped bending trajectory. The wave-shaped bending arrangement of the solder paste can more effectively target the larger annular gap between the tower drum 9 and the tower drum flange 901, making the solder paste more evenly distributed in the annular gap. It should be noted that before the annular gap is welded, the joint between the tower drum 9 and the tower drum flange 901 needs to be pre-opened with a U-shaped weld groove. The above action of the wave-shaped oscillation of the discharge pipe 16 to extrude the solder paste is mostly carried out in the U-shaped annular gap. Because the fixed frame 13 is inclined along the rotation of the first rolling ball 12 to approach the discharge pipe 16 in the vertical direction, the inclination of the fixed frame 13 causes the two arc-shaped scrapers 49 at the lower end of the fixed frame 13 to be pressed against the outer wall of the tower drum 9 and the tower drum flange 901, and the two arc-shaped scrapers 49 are symmetrically located along the annular gap. When the fixed frame 13 rotates in the horizontal direction clockwise and counterclockwise, the third guide rod 44 on the outer wall of the fixed frame 13 will rotate at this time, and the arc-shaped scrapers 49 pressed against the outer wall of the tower drum 9 and the tower drum flange 901 cannot rotate due to profile problems. Therefore, the fixed frame 13 will rotate along the rotation connection of the second rolling ball 38 at this time, and the third guide rod 44 moves during rotation, and the movement track of the third guide rod 44 will touch the third inclined surface 53 on the outer wall of the third abutting block 52, causing the third abutting block 52 to be stressed downward. The first abutting block 45 is pressed downward, the first abutting block 45 moves downward, the first abutting block 45 compresses the compression spring 43 with the lifting frame 42 to generate displacement, and the lifting frame 42 enters the groove 41. At this time, the first inclined surface 46 will abut against the second inclined surface 51, causing the two second abutting blocks 50 to approach each other, and the arc-shaped scrapers 49 approach each other with the second abutting blocks 50. The two 50 will scrape and gather the solder paste overflowing near the U-shaped groove of the annular gap, so that the solder paste is more gathered on the annular gap, and the solder paste is more evenly arranged on the annular gap. When the second guide rod 37 slides along the first annular groove 25 for one circle, it will finally abut against the first block 29, causing the first block 29 to rotate along the third horizontal shaft 28 and twist the first torsional spring 30 to facilitate resetting, so that the second guide rod 37 passes through the block of the first block 29. Then, the motor 2 is started in reverse, causing the second guide rod 37 to slide into the second annular groove 26 along the arc-shaped groove 27. During sliding, the second guide rod 37 rises, and the second guide rod 37 rotates with the discharge pipe 16 and the fixed frame 13. The fixed frame 13 rotates along the rotation of the first rolling ball 12, causing the fixed frame 13 to incline towards the side close to the electric welder 15. At this time, the output end of the electric welder 15 abuts against the weld, and the inner tooth ring 22 rotates to make the electric welder 15 weld the annular gap in a wave path along the annular gap. It should be noted that before the annular gap is welded, the joint between the tower drum 9 and the tower drum flange 901 needs to be opened in advance.

10. The method for using the flange welding equipment for tower processing according to claim 9, characterized in that: The following welding methods are also included: S1. First, the tower (9) and tower flange (901) to be welded are placed on the surface of the first transverse axis (3) and the second transverse axis (4) by a crane, and then the first cylinders (5) on both sides are started to push and move the tower (9) and the tower flange (901) along the surface of the first transverse axis (3) and the second transverse axis (4) until the joint of the tower (9) and the tower flange (901) is below the electric welder (15), thereby completing the preparation work; S2, then start the motor (2). After the motor (2) is started, the inner gear ring (22) starts to rotate. When the inner gear ring (22) rotates, it causes the fixed frame (13) to tilt along the outer wall of the first ball (12). At this time, the discharge pipe (16) and the ball (19) hit the joint between the tower flange (901) and the tower (9), and as the inner gear ring (22) rotates, the paste solder paste in the fixed frame (13) can be squeezed out of the discharge pipe (16) at the joint in a curved manner. The curved extrusion can make the solder paste more evenly distributed, and at this time, the two arc scrapers (49) repeatedly move closer to each other and then away from each other, causing the bent solder paste to be scraped and gathered toward the central joint, so that the solder paste is more evenly distributed at various positions of the annular weld. S3, then the motor (2) is rotated in the reverse direction, at which time the inner gear ring (22) rotates in the reverse direction, causing the fixed frame (13) to tilt along the outer wall of the first ball (12) in the opposite direction of S2, causing the electric welder (15) to contact the weld. At this time, the electric welder (15) is started, and the electric welder (15) welds the weld with a wave-bent welding curve, which just corresponds to the extrusion path of the solder paste. The wave-bent welding curve cooperates with the rotating weld, which can better weld the weld, and the entire weld is heated evenly; S4. After the welding is completed, the first cylinder (5) on one side is started to push out the tower (9) and tower flange (901) connected after the welding, thereby completing the welding process.
