For example, the bottom of the movable welding frames 2 is provided with movable wheels 3. The welding frames 2 include a base 21 and a fixed frame 22 hinged to the base 21. A flip clamping mechanism 4 is provided on the welding frame 2, and the flip clamping mechanism 4 is used to clamp and fix the tower body 1, and drive the tower body 1 to flip. An opening and closing mechanism 5 is provided between the base 21 and the fixed frame 22 in the same group of welding frames 2, and the opening and closing mechanism 5 is used to realize the fixation of the base 21 and the fixed frame 22 away from the hinged part of the two. A telescopic rod 6 is fixedly provided between two adjacent welding frames 2. The telescopic rod 6 is used to make the adjacent welding frames 2 form a stable whole, improve the support stability of the entire welding tooling, and reduce the welding quality problems caused by the shaking of the welding frames 2; and the telescopic rod 6 allows the multiple sections of the tower body 1 to be telescoped within a certain range, so that when welding multiple tower bodies 1, the concentricity of the tower body 1 can be quickly adjusted and maintained, ensuring the precise alignment between the tower bodies 1 during the welding process.

[0030] When welding the steel structure of the power steel pole, first place the tower body 1 of the power steel pole tower on the base 21 of multiple groups of welding frames 2, then fix the base 21 and the fixing frame 22 through the opening and closing mechanism 5 to form a closed-loop support, and then clamp and fix the tower body 1 through the flipping clamping mechanism 4 to ensure the stability of the tower body 1 during the welding process. Then, the staff drives the tower body 1 to flip through the flipping clamping mechanism 4 according to the welding needs, so that the tower body 1 is accurately flipped to the required welding angle, which is convenient for all-round welding operations of the tower body 1 and accessories in different directions of the tower body 1. After the welding is completed, the staff releases the tower body 1 through the opening and closing mechanism 5, and then safely unloads the welded tower body 1 to prepare for the next round of welding operations.

[0031] In some embodiments, reference Figure 2 and Figure 3 The flip clamping mechanism 4 includes two rotating frames 41 rotatably connected to the welding frame 2. The two rotating frames 41 are semi-circular and symmetrically arranged. The rotating frames 41 are sleeved on the outside of the tower body 1. A plurality of pressing rollers 42 are arranged on the rotating frame 41. The plurality of pressing rollers 42 are evenly spaced along the same circumference and abut against the outer wall of the tower body 1.

The flip transmission assembly 43 is used to synchronously drive the plurality of pressing rollers 42 to move closer to or away from each other, and to control the rotation of the pressing rollers 42. A self-locking drive assembly 44 is arranged between one of the rotating frames 41 and the welding frame 2. The self-locking drive assembly 44 is used to drive the rotating frame 41 to rotate, and at the same time lock the position of the rotating frame 41 after rotation.

[0032] When fixing the tower body 1, the tower body 1 must first be placed between two symmetrically arranged rotating frames 41, which are sleeved on the outside of the tower body 1. Then, the self-locking drive component 44 is started, and the self-locking drive component 44 drives one of the rotating frames 41 to rotate, and the other rotating frame 41 follows. The rotating frame 41 synchronously drives multiple clamping rollers 42 to approach each other through the flipping transmission component 43, so that the clamping rollers 42 abut against the outer wall of the tower body 1, and the tower body 1 can be fixed. When the tower body 1 needs to be flipped and changed direction, the flip transmission component 43 is used to drive multiple clamping rollers 42 to rotate, and the clamping rollers 42 can drive the tower body 1 to flip to the required welding angle. The flip transmission component 43, the self-locking drive component 44 and the like cooperate to realize the fixing and flipping of tower bodies 1 of different diameters, which is suitable for welding of power steel pole towers of various specifications, thereby improving the versatility and adaptability of the fixing tooling; and the self-locking drive component 44 can also lock the position of the rotating frame 41 after rotation, thereby ensuring that the tower body 1 can be stably locked after flipping to the required welding angle, thereby avoiding accidental movement of the tower body 1 during welding, thereby improving welding quality and safety.

A flip component 433 is arranged between the pressing roller 42 and the transmission rod 431, and the flip component 433 is used to drive the pressing roller 42 to rotate. Exemplarily, the flip component 433 includes a hub motor 4331 arranged inside the pressing roller 42, and a mounting frame 4332 is arranged between the hub motor 4331 and the transmission rod 431.

[0034] When the self-locking drive assembly 44 drives the rotating frame 41 to rotate, the rotating frame 41 synchronously drives the guide sleeve 432 to move, and the guide sleeve 432 drives one end of the transmission rod 431 to rotate. At the same time, the other end of the transmission rod 431 drives the clamping roller 42 to move, thereby synchronously driving multiple clamping rollers 42 to move closer to or away from each other, thereby achieving the fixation and release of the tower body 1; when it is necessary to adjust the flipping angle of the tower body 1, the hub motor 4331 is started, and the torque of the hub motor 4331 is directly used to drive the clamping roller 42 to rotate. Multiple clamping rollers 42 rotate synchronously under the drive of the hub motor 4331, driving the tower body 1 to flip to the required welding angle, thereby achieving precise positioning of the tower body 1.

[0035] In some embodiments, reference Figure 3 and Figure 4 The self-locking drive assembly 44 includes a sector gear ring 441 fixedly sleeved on the outer side of the rotating frame 41, a rotating shaft 442 is rotatably connected to the welding frame 2, a driving gear 443 and a worm wheel 444 are fixedly sleeved on the rotating shaft 442, and the driving gear 443 and the sector gear ring 441 are meshed with each other.

[0036] When the rotating frame 41 is driven to rotate by the self-locking driving component 44, the driving motor 446 is first started, and then the driving motor 446 drives the worm wheel 444 to rotate through the worm 445, and the worm wheel 444 drives the rotating shaft 442 and the driving gear 443 to rotate, and the driving gear 443 drives the rotating frame 41 and the fan-shaped gear ring 441 fixed on the outside of the rotating frame 41 to rotate, so that the rotation of the rotating frame 41 can be realized, and when the second limiting rod 4472 abuts against one of the first limiting rods 4471, it indicates that the rotating frame 41 is in the initial state, and when the second limiting rod 4472 abuts against the other first limiting rod 4471, it indicates that the rotating frame 41 rotates to the extreme position, preventing the rotating frame 41 from excessively rotating and separating from the welding frame 2.

An anti-slip spring 53 is sleeved on the outer side of the locking rod 52, and the anti-slip spring 53 always gives the locking rod 52 a force toward the locking groove 212. The anti-slip spring 53 is used to give the locking rod 52 a continuous force toward the locking groove 212, ensuring that the locking rod 52 is not easily accidentally disengaged due to vibration, impact or other external forces after being inserted into the locking groove 212. The end of the locking rod 52 near the locking groove 212 is provided with a chamfer 521, which is used to reduce the resistance when the locking rod 52 is inserted into the locking groove 212, so that the locking rod 52 can be inserted into the locking groove 212 more easily and smoothly.
