DEVICE FOR THERMAL CUTTING OF PIPES Russian patent published in 2018 - IPC B23K10/00 B23K37/02 

FIELD: machine engineering.

SUBSTANCE: device has a base, a cart moving along the base guides and provided with pair of running wheels, a hub rigidly secured on the base and bearing a carriage moving in the radial direction with a plasma cutter, a plasma cutter rotation drive, and of drive for carriage movement. The device is also provided with additional running wheels and side rollers mounted on the cart symmetrically relative to its vertical axis on cantilever ends. The side rollers forming the basic support surface are located on one side of the cart, and the side rollers which lock the position relative to the cart base are located on the other side of the carts on the shafts with eccentricity. The plasma cutter is mounted on the axle in the supports and provided with a pivot drive relative to the carriage vertical axis, while on one of the supports there is a fixing device for inclination of the cutter.
