[0032] Working principle:

[0033] In use, by arranging the supporting device 3, when the two pipe materials are welded, they are pushed from one end of the horn column 32, when the pipe material enters, the sliding plate 33 is pushed to move, the sliding block 34 connected to the sliding plate 33 will slide in the groove on the horn column 32, and at the same time drive the connecting column 35 connected in rotation to move, so as to move the rotating block 36, due to the action of the compression spring 39, the movable rod 38 is driven to move, at the same time, the roller 37 will support the entering steel pipe and will not affect its continuous entering, at this time, the positioning column 31 passes through the cooperation of the positioning device 4, the positioning column 31 extrudes the push rod 43, the push rod 43 moves on the sliding groove 44, the sliding groove 44 is fixed on the fixed plate 45, the fixed plate 45 is fixed on the moving column 46, the push rod 43 drives the clamping device 42 to clamp the pipe material, so that the two ends of the entering pipe material enter the center of the positioning device 4, which is convenient for subsequent clamping.

[0034] In use, by setting the positioning device 4, when the pipe enters, the moving push column 43 drives the baffle 47 fixedly connected to the moving column 46 to move, the baffle 47 pushes the sliding box 411 to move, so that the trapezoidal fixed block 414 on the extension rod 412 enters the inside of the opposite sliding box 411, because the sliding box 411 has a hole inside to accommodate the telescopic spring 415 and the blocking column 416, when the trapezoidal fixed block 414 enters, it will compress the blocking column 416 to slide back, and then reset under the action of the telescopic spring 415, which will block the trapezoidal fixed block 414, play a connecting role, until the trapezoidal movable block 413 is also pushed inwards to pull out after the blocking column 416, cooperate with the clamping device 42, when the push column 43 extrudes the sliding inclined plate 424, the arc-shaped plate 425 fixedly connected to the sliding inclined plate 424 will extrude the pipe, and the pipe will be extruded to the center position, cooperate with the connecting device 41, can effectively fix the pipe position, so that the two pipes are concentric and cannot move randomly.

[0035] In use, by setting the clamping device 423, when the pipe is clamped, rotating the rotating ring 422, the rotating ring 422 sliding on the two surfaces of the first fixed ring 421 and the second fixed ring 426 will drive the first rotating rod 4231 to move, the first rotating rod 4231 moves on the sliding groove 4232 to limit the moving direction, so that when the rotating ring 422 drives the first rotating rod 4231 to move away, the lower end will move upward in the sliding groove 4232, the second rotating rod 4233 connected to the lower end of the first rotating rod 4231 will pull the clamp plate 4234 inward when pulled upward, at this time the clamp plate 4234 will clamp the sliding inclined plate 424, so that the supporting device 3 does not need to always apply pressure to the push column 43 for pipe clamping, and the supporting device 3 can be moved after clamping. Because of the setting of the roller 37, when it moves, it will not generate too much friction force to the pipe, so as not to affect the butt joint and welding, at this time the outwardly pulled supporting device 3 can be moved along the slide rail 2 to the end of the pipe away from the welding to implement support, thereby reducing the vibration and bending of the pipe.

[0036] When in use, the exhaust fan is stored in the base 1 by setting the storage device 5. After the pipe is docked and fixed, the movable columns 46 on both sides are pulled apart to drive the support rods 54 to be pulled apart. The pulled support rods 54 make the rotatably connected support plate 51 rise, and the exhaust fan can be set in the horizontal plate 52. The movable ring 53 is pulled to block a certain amount of dust and smoke above the welding ground. The fixing device 55 is set to fix the support rod 54 so that the movable columns 46 on both sides will not return due to the gravity of the objects on the support plate 51. When the movable column 46 reaches a certain position, it pushes the push-pull ring 551, driving the connecting block 552 to move downward and generate pressure on the pressure block 553, so that the first thrust rod 554 is driven and squeezed to rotate, thereby driving the second thrust rod 555 to move, so that the fixing clamp 556 is squeezed inward, supporting the support rod 54, and playing the role of preventing the objects stored after being pulled from returning again.
