Abstract
A mobile rail welding machine comprises a frame, a hydraulically driven flash butt welding device, a "Thermit" welding unit and preferably an electric arc welding device mounted on the frame for selectively flash butt welding, "Thermit" welding or arc welding abutting rail section ends of a track rail, and a weld burr removal device adjustably mounted on the frame for selectively removing weld burrs at either rail.
Claims10
A mobile rail welding machine mounted on a track for mobility in an operating direction, the track being comprised of rails consisting of rail sections having abutting ends and ties supporting the rail sections, which comprises the combination of
- (a) a heavy frame supported on the track rails for movement in the operating direction,
- (b) a hydraulically driven flash butt welding device for welding the abutting rail section ends of a selected one of the rails mounted on the frame,
- (c) a "Thermit" welding unit for welding the abutting rail section ends of a selected one of the rails mounted on the frame whereby the abutting rail section ends may be selectively flash butt welded or "Thermit" welded, and
- (d) a weld burr removal device adjustably mounted on the frame for selectively removing weld burrs at either one of the rails.
