The movement of the symmetrical trapezoidal splints 220 drives the sliding sleeve 229 to slide on the outer wall of the sliding rod 228, thereby improving the stability of the symmetrical trapezoidal splints 220 when moving. The trapezoidal clamping plate 220 is said to move and approach the steel tower to clamp the steel tower, and the outer wall of the steel tower is protected by the rubber protective pad 2201 to prevent the steel tower from being damaged. Then the stepper motor three 39 is started, thereby driving the conical gear three 38 to rotate, and the conical gear three 38 rotates to make the right conical gear two 37 rotate, thereby driving the right conical gear one 36 to rotate, and the right conical gear one 36 rotates to drive the rotating rod one 34 to rotate on the inner wall of the movable sleeve one 35, thereby driving the toothed disc one 32 to rotate, and the toothed disc one 32 rotates to drive the toothed belt 31 to rotate, thereby driving the left toothed disc one 32, the rotating rod one 34, the conical gear one 36, and the conical gear two 37 to rotate. The toothed belt 31 is protected by the limit plate 1 33, and the two rotating components 21 are driven to move by the rotation of the two conical teeth 2 37, and the connecting rod 1 218 is driven to rotate by the rotation of the conical teeth 2 37, so that the gear 216 is rotated, and the outer gear ring 215 drives the limit ring 213 to rotate on the inner wall of the support sleeve 212 through the rotation of the gear 216, so that the fixed ring 1 214 is driven to rotate by the rotation of the limit ring 213, so that the fixed ring 1 214 drives the steel tower fixed by the clamping component 22 at the other end to rotate, and the pneumatic push rod 2 42 can be started as needed to adjust the welding distance, and then the automatic welding operation can be performed by starting the connecting plate 2 44,At the same time, the filter assembly 47 is driven to perform a linkage effect. When the toothed belt 31 rotates, the toothed disc 2 401 and the connecting shaft 1 40 are driven to rotate, so that the limiting rod 49 rotates on the inner wall of the movable sleeve 2 48. The rotation of the connecting shaft 1 40 drives the belt 403 so that the connecting shaft 2 404 drives the connecting rod 2 405 to rotate on the inner wall of the movable sleeve 3 406, thereby driving the conical gear 407 to rotate. The conical gear 407 rotates so that the conical gear 6 479 rotates, and then drives the rotating rod 2 477 to rotate on the inner wall of the supporting cylinder 478. The conical gear 7 470 rotates through the rotation of the supporting cylinder 478, and drives the conical gear 5 475 to rotate. The conical gear 5 475 rotates so that the connecting rod 3 473 rotates and drives the fan blade 474 to rotate, so as to extract the gas generated during welding. When the pneumatic push rod 42 is activated, the fixed elbow 4702 is driven to move so that the telescopic tube 4701 is extended and retracted. The gas generated during welding enters the interior of the installation box 471 through the fixed elbow 4702 and the telescopic tube 4701, and is filtered through the activated carbon filter plate 4708 by the action of the fan blade 474, so that the gas is discharged. When the activated carbon filter plate 4708 needs to be replaced, the four anti-slip knobs 4714 need to be turned to make the spiral rod 4713 detach from the inner wall of the internal thread groove 4705, so that the protective mesh plate 4711 can be taken out, so that the baffle 4710 releases the limit on the handle 4709. At this time, the two handles 4709 are pulled to drive the movable frame 4706 to be pulled out from the inner wall of the installation box 471, so that the activated carbon filter plate 4708 can be removed and replaced.

[0024] The working principle of the present invention is as follows: by starting the stepper motor 15, the rotating shaft 14 drives the screw rod 16 to rotate, so that the rectangular block 19 moves on the outer wall of the screw rod 16, and then pushes the pneumatic push rod 18, the rectangular block 19, the trapezoidal block 10, and the roller 101 to move. The two stepper motors 15 and the rectangular block 19 are adjusted as needed, and then the steel tower is placed on the outer wall of the roller 101, and the fixing structure 2 is started to fix the steel tower, so as to achieve accurate clamping and positioning of the steel tower; When the steel tower is placed on the top of the roller 101 and one end of it enters the interior of the limit ring 213, the stepper motor 224 can be started to rotate the shaft 223, thereby driving the bidirectional threaded rod 225 to rotate. The two sliders 227 are moved inward and outward at the same time by the rotation of the bidirectional threaded rod 225, thereby driving the two symmetrical trapezoidal clamping plates 220 to move in opposite or opposite directions at the same time. The movement of the symmetrical trapezoidal clamping plates 220 drives the sliding sleeve 229 to slide on the outer wall of the sliding rod 228, thereby improving the stability of the symmetrical trapezoidal clamping plates 220 when moving. The two symmetrical trapezoidal clamping plates 220 move and approach the steel tower so that it clamps the steel tower, and the rubber protective pad 220 is used. 1 has the effect of protecting the outer wall of the steel tower to prevent the steel tower from being damaged, and then starting the stepper motor three 39, thereby driving the conical gear three 38 to rotate, and the conical gear three 38 rotates to make the right conical gear two 37 rotate, thereby driving the right conical gear one 36 to rotate, and the right conical gear one 36 rotates to drive the rotating rod one 34 to rotate on the inner wall of the movable sleeve one 35, thereby driving the toothed disc one 32 to rotate, and the toothed disc one 32 rotates to drive the toothed belt 31 to rotate, thereby driving the left toothed disc one 32, the rotating rod one 34, the conical gear one 36, and the conical gear two 37 to rotate, and the toothed belt 31 is protected by the limit plate one 33, and the two conical gear twos 37 rotate to The two rotating components 21 are driven to move, and the connecting rod 1 218 is driven to rotate through the rotation of the conical gear 2 37, thereby causing the gear 216 to rotate. The outer gear ring 215 drives the limiting ring 213 to rotate on the inner wall of the support sleeve 212 through the rotation of the limiting ring 213, so that the fixing ring 1 214 is driven to rotate, so that the fixing ring 1 214 drives the steel tower fixed by the clamping component 22 at the other end to rotate. The pneumatic push rod 2 42 can be started as needed to adjust the welding distance, and then the connecting plate 2 44 can be started to perform automatic welding operation, and at the same time, the filter component 47 is driven to perform linkage effect. When the toothed belt 31 rotates, it drives the toothed disc 2 401 and the connecting plate 44. The rotation of shaft 1 40 causes the limiting rod 49 to rotate on the inner wall of movable sleeve 2 48, and the rotation of connecting shaft 1 40 drives the belt 403 to make connecting shaft 2 404 drive connecting rod 2 405 to rotate on the inner wall of movable sleeve 3 406, thereby driving conical gear 407 to rotate, and the rotation of conical gear 407 causes conical gear 6 479 to rotate, thereby driving rotating rod 2 477 to rotate on the inner wall of supporting cylinder 478, and the rotation of supporting cylinder 478 causes conical gear 7 470 to rotate, and drives conical gear 5 475 to rotate, and the rotation of conical gear 5 475 causes connecting rod 3 473 to rotate and drives fan blade 474 to rotate, so that the gas generated during welding is extracted and filtered,When the pneumatic push rod 42 is activated, the fixed elbow 4702 is driven to move so that the telescopic tube 4701 is extended and retracted. The gas generated during welding enters the interior of the installation box 471 through the fixed elbow 4702 and the telescopic tube 4701, and is filtered through the activated carbon filter plate 4708 by the action of the fan blade 474, so that the gas is discharged. When the activated carbon filter plate 4708 needs to be replaced, the four anti-slip knobs 4714 need to be turned to disengage the spiral rod 4713 from the inner wall of the internal thread groove 4705, so that the protective mesh plate 4711 can be taken out, and the baffle 4710 can release the limit on the handle 4709. At this time, the two handles 4709 are pulled to drive the movable frame 4706 to be pulled out from the inner wall of the installation box 471, so that the activated carbon filter plate 4708 can be removed and replaced.
