[0026] The staff passes through the side and upper part of the climbing mechanism single-section cylinder 5, and then adjusts the position of the welding equipment through the lifting mechanism to splice the butt welds between the two single-section cylinders 5. In this way, the safety and reliability of the outer ring seam welding of the single-section cylinder 5 are enhanced.

[0027] As a preferred solution, the climbing mechanism includes a ladder 31, a reel 32 and a traction rope 33. The bottom end of the ladder 31 is hinged to the bottom of the bracket 11 and is located on a side close to the roller frame assembly 2. The reel 32 is arranged on the bracket 11. One end of the traction rope 33 is connected to the top of the ladder 31, and the other end of the traction rope 33 is connected to and wound on the reel 32. The reel 32 has a braking function.
