Abstract

The invention discloses a C-shaped pipeline cutting knife. The cutting knife comprises a support, wherein a cutting tool is connected with one end of the support, the cutting tool comprises a tool rest with a C-shaped section, a gear ring is fixedly arranged on a surface of the knife rest along the circumferential direction, a gear motor is fixedly installed on a side wall of the support through screws, a pinion is mounted on a motor shaft of the gear motor, the pinion is meshed with the gear ring, a lifting assembly is installed at upper end of the knife rest, a cutting knife wheel is installed at a bottom end of the lifting assembly, a transmission assembly is installed at a lower end of the knife rest, a to-be-cut pipe is placed between the knife wheel and the transmission assembly, anarc-shaped guide rail is fixedly installed on a side wall of the knife rest in the circumferential direction of the knife rest, and four sliding blocks are fixed to a side face of the support throughscrews. The cutting knife is advantaged in that a pipe opening of a cut pipeline is not deformed, a notch is flat and smooth, follow-up maintenance and welding are facilitated, no cuttings or cuttingmedium exists after cutting, no secondary pollution is caused to the pipeline, and mounting and dismounting are convenient.

Description

technical field [0001] The invention belongs to the technical field of pipe cutting equipment, and in particular relates to a C-shaped pipe cutting knife. Background technique [0002] Pipelines are widely used in petrochemical, thermal / nuclear power, shipping and other basic industrial facilities. In the case of blockage, damage, corrosion, etc. inside the pipeline, it is necessary to remove the faulty part of the pipeline. Existing pipe cutting methods include the following: (1) cold cutting technology, using blade extrusion cutting; this cutting technology can only be operated manually, and is not applicable in toxic and harmful gas environments or radioactive environments; Installed on the pipeline and constitute the overall frame, the cutting process is relatively slow; (2) sawtooth cutting, use high-speed rotary saw blade for cutting; it is easy to cause a large amount of metal powder to enter the pipeline, forming secondary pollution, and the cut has burrs; (3) ) Th...
