[0028] Working principle: In the prior art, when welding pipes or rollers, a support frame fixed on the ground is used to support the pipes at a fixed point. This support device cannot be applied to the welding requirements of pipes of various sizes and lengths. According to the different pipe sizes, the cylinder 5 is started, and the piston rod of the cylinder 5 pushes the fixed plate 6 to move. Under the action of the upper limit plate 4 on the outer side of the support plate 7 and the lower limit plate at the bottom, the two rollers 3 move toward or in the opposite direction to the two support frames. The two rollers 3 in the middle and the two rollers 3 at the two ends are tangent to the outer surface of the pipe, which meets the welding requirements of pipes of different sizes and specifications.

When the distance between the first support frame 2 and the second support frame 25 is adjusted, the second support frame 25 slides toward the connecting plate until it contacts the anti-collision plate 17, and then the anti-collision spring 18 is linearly compressed under the action of the sliding rod until the anti-collision spring 18 is compressed to the limit, preventing the first rotating wheel 22 and the second rotating wheel 23 from colliding with the connecting plate, meeting the welding requirements of pipelines of different lengths. When welding the pipeline, the rotating motor 1 is started. 5. The roller 3 is driven to rotate the pipe on the roller 3 under the action of the first rotating wheel 22 and the second rotating wheel 23. The pipe only needs to be welded in the same posture to avoid the worker welding the pipe up and down. When the pipe is welded with pipes of different diameters, the height of the welding place is different. By rotating the threaded rod 14, the thread on the threaded rod 14 cooperates with the thread in the threaded barrel 13 to increase or decrease the front end height of the threaded rod 14 to adapt to the height of the welding place. When the pipe is welded, a layer of flux skin will be formed at the welding place. If the flux skin is not cleaned, the welding effect cannot be known. Start the knocking motor 9, the gear 10 starts to rotate, and at the same time drives the triangular block 11 to do up and down reciprocating motion, and the connecting rod 20 also does the same action, and its upper end impacts and cleans the solder coating. When the connecting rod 20 moves upward, the baffle 19 compresses the return spring 21 in the slide tube 12. When the connecting rod 20 falls, the return spring 21 stretches and quickly returns the connecting rod 20. This process is continuous and stable, and the solder coating of the welding place can be quickly cleaned. When the pipeline welding is completed and the solder coating cleaning is completed, turn off the power, remove the pipeline, and then clean the support frame. After the cleaning is completed, the welding work is completed.
