[0032] A motor 103a and a roller 103b are respectively disposed on two sides of the fixing seat 102 .

[0033] Specifically, one end of the rotating shaft passes through the fixing seat 102 and is connected to the output end of the motor 103a.

[0034] Specifically, there are two rollers 103 b , and the two rollers 103 b are evenly distributed on the fixing seat 102 .

[0035] Furthermore, the grouting part 104 includes a stiffening ring 104a disposed on the roller 103b, a grouting port 104b disposed on the stiffening ring 104a, and a steel pipe 104c disposed on the stiffening ring 104a.

[0036] The side walls of the stiffening ring 104a are in contact with the two rollers 103b respectively.

[0039] The stiffening ring 104a is sleeved on the side wall of the steel pipe 104c.

[0040] Specifically, before placing the stiffening ring 104a on the roller 103b, the stiffening ring 104a and the steel pipe 104c are first welded to perform a simple fixation, and then the steel pipe 104c is laid down so that the side wall of the stiffening ring 104a contacts the side wall of the roller 103b.

[0045] Operation process: In order to prevent the steel pipe 104c from blocking the grouting port 104b during welding, compared with the position of the grouting port 104b of the existing stiffening ring 104a, the position of the grouting port 104b in the present invention leaves a gap from the steel pipe 104c to prevent the grouting port 104b from being blocked during welding. The staff sets the stiffening ring 104a on the outer wall of the steel pipe 104c, and when the position of the stiffening ring 104a on the steel pipe 104c is determined, spot welding is performed first, and then the steel pipe 104c is laid down so that the stiffening ring 104a is located on the roller 103b, and the motor 103a is started. The motor 103a drives the roller 103b to rotate, and the roller 103b drives the steel pipe 104c to rotate, and the stiffening ring 104a and the steel pipe 104c are welded around by the welding gun 305b.

[0059] Specifically, two ends of the first spring 203f are connected to the plug plates respectively.

[0060] Specifically, when the moving block 203a moves to a specified position, the first spring 203f can drive the inserting blocks 203e on the moving plates 203d at both ends to be inserted into the interior of the slot 202 to complete the fixation.

[0061] Furthermore, the guide portion 204 includes a fixed plate 204a disposed on the movable plate 203d, and an inclined groove 204b and a vertical groove 204c disposed on the fixed plate 204a.

[0069] The side wall of the fixed block 205b is connected to the follower ring 205c.

[0070] Operation process: When the staff needs to adjust the position of the moving block 203a, the staff can pull the follower ring 205c to rise, the follower ring 205c can drive the fixed block 205b to rise, and the fixed block 205b drives the extrusion rod 205a to rise, so that the extrusion rod 205a gradually moves from the bottom of the inclined groove 204b to the top of the inclined groove 204b. Since the extrusion rod 205a can only be lifted in the longitudinal position, when the extrusion rod 205a rises, it drives the fixed plate 204a to move toward the follower ring 205c, and the fixed plate 204a drives the first A spring 203f contracts, the fixed plate 204a drives the movable plate 203d to move, and the movable plate 203d drives the socket to disengage from the inside of the slot 202. At this time, the staff can push the movable block 203a, adjust the position of the movable block 203a, and after reaching the specified position, release the follower ring 205c, and the follower ring 205c drops. The first spring 203f recovers and drives the fixed plate 204a to move, the fixed plate 204a drives the movable plate 203d, and the movable plate 203d drives the plug 203e to be reinserted into the inside of the slot 202 to complete the fixation.

[0083] The retaining ring 303f is arranged at the bottom of the rotating sleeve 303e.

[0084] Specifically, the rotating sleeve 303e is prevented from being separated from the moving block 203a.

[0085] A first thread 303g is disposed on the outer wall of the rotating sleeve 303e, and the first thread 303g is adjacent to the bottom of the rotating sleeve 303e.

[0086] Specifically, the height dimension of the first thread 303g is half of the height dimension of the rotating sleeve 303e.

[0103] A telescopic tube 305c is installed on the side wall of the welding gun 305b.

[0105] Specifically, one end of the telescopic tube 305c away from the welding gun 305b extends to the inside of the arc groove 305d, and the telescopic tube 305c can move inside the arc groove 305d, and the telescopic tube 305c cannot be separated from the inside of the telescopic tube 305c.

[0106] Specifically, the cross-sectional dimension of the end portion of the telescopic tube 305c is matched with the width dimension of the arc-shaped groove 305d.

[0107] Operation process: When using welding gun 305b for welding, in order to ensure that welding gun 305b is aligned with the weld between stiffening ring 104a and steel pipe 104c, since steel pipe 104c itself is relatively heavy and it is troublesome to move steel pipe 104c itself, the staff needs to manually adjust the position of welding gun 305b.

[0108] The staff rotates the rotating sleeve 303e, so that the rotating sleeve 303e rises on the inner wall of the threaded opening 301. When the rotating sleeve 303e rises, it drives the rotating disk 303d to rise, the rotating disk 303d drives the lifting rod 303c to rise, the lifting rod 303c drives the limiting ring 303b to rise, the limiting ring 303b drives the following ring 205c to rise, the following ring 205c drives the fixing block 205b, the fixing block 205b drives the extrusion rod 205a, and when the extrusion rod 205a rises, the two fixing plates 204a approach each other, and the fixing plate 204a is fixed. The fixed plate 204a drives the movable plate 203d, and the movable plate 203d drives the insert block 203e to disengage from the inside of the slot 202. At this time, the staff can push the movable block 203a horizontally to make the movable block 203a move inside the first through-hole 201. When reaching the specified position, the staff reverses the rotating sleeve 303e to make the rotating sleeve 303e descend, so that the follower ring 205c returns to the initial position, completing the locking of the movable block 203a. At this time, the rotating sleeve 303e is not connected to the threaded opening 301, but is just in contact with it.

[0109] When the moving block 203a reaches the approximate position, the height of the position of the welding gun 305b needs to be adjusted. At this time, the staff can rotate the turntable 303d, and the turntable 303d drives the lifting rod 303c to rotate, and the rotating rod drives the limit ring 303b to rotate, and the limit ring 303b drives the long tube 302 to rotate. When the long tube 302 rotates, the long tube 302 drives the threaded rod 305a to rotate together, and the threaded rod 305a drives the welding gun 305b to rotate. The welding gun 305b drives the telescopic tube 305c to move inside the arc groove 305d. When the telescopic tube 305c contacts one end of the inner wall of the arc tube, the telescopic tube 305c cannot move due to the limitation of the arc groove 305d. At this time, the long tube 302 rotates, and the threaded rod 305a cannot continue to rotate. The threaded rod 305a decreases compared to the position of the long tube 302, and the threaded rod 305a drives the welding gun 305b to decrease and approach the weld.

[0110] When the welding gun 305b is close enough to the weld, it is necessary to adjust the nozzle of the welding gun 305b to align with the weld, and directly rotate the turntable 303d in the opposite direction to make the telescopic rod move in the opposite direction inside the arc groove 305d. At this time, the relative position of the threaded rod 305a and the long tube 302 will not change. When the welding gun 305b reaches the specified position, the worker presses the turntable 303d, and the turntable 303d drives the rotating sleeve 303e and the lifting rod 303c to descend together. The lifting rod 303c drives the limit ring 303b to descend, and the limit ring 303b drives the follower ring 205c to descend. The dynamic ring 205c drives the extrusion rod 205a to descend inside the vertical groove 204c, the limit ring 303b drives the first limit plate 304f to descend, and the lifting rod 303c drives the hook 304e to descend. When the hook 304e descends to the inside of the annular groove 304a, part of the hook 304e enters the inside of the annular groove 304a to complete the locking. At this time, the first limit plate 304f and the second limit plate 304g are staggered with each other to complete the locking to prevent the long tube 302 from rotating. At this time, the welding gun 305b is locked, which is convenient for welding the stiffening ring 104a.

[0111] When welding is completed, the staff pulls the pull ring 304c, and the pull ring 304c can drive the pull rod 304b to rise, and the pull rod 304b drives the pull rope 304d to rise, and the pull rope 304d drives the two hooks 304e to approach each other, so that the hook 304e is disengaged from the inside of the annular groove 304a, and the second spring 303h recovers to drive the limit ring 303b to rise, and the limit ring 303b drives the follower ring 205c to rise, and the follower ring 205c drives the extrusion rod 205a to rise to the bottom of the inclined groove 204b, and the first limit plate 304f rises and separates from the second limit plate 304g, and the hook 304e rises on the side wall of the long tube 302 until the second spring 303h is fully recovered, which is convenient for next use.
