Abstract
The utility model relates to a steel ring rail type flame cutter which is favorably adapted for cutting the steel tube. The utility model comprises a driving device and a float pressing mechanism, and also comprises an arc structure still ring and a moving ring. The still ring is provided with a circular chain, and is also provided with an adjusting screw bolt. The circular chain is provided with a locking device which is used for fixing the still ring. The moving ring is provided with a chain and a support which is used to mount a cutting torch seat. The driving device is fixed on the float pressing mechanism. The float pressing mechanism is fixed with the still ring by a fixed plate. The cutting torch is driven by the rotation of the moving ring along the steel tube to do circular motion, and thus the cutting goal is reached. As the moving ring is not contacted with the cutting surface of the steel tube, the moving ring is not affected by the screw welding seam existing on the cut steel tube, the linearity error is not easily generated when in cutting, and the surface roughness of the pipe material is reduced after the pipe material is cut. The utility model has easy and simple operation, safe use, wide application range and good effect.
