Abstract
A mobile rail welding machine comprises a frame, two undercarriages supporting the frame, a hydraulically driven flash butt welding unit for welding abutting rail section ends of a track rail mounted on the frame intermediate the undercarriages, a hydraulically driven weld burr removal unit mounted on the frame intermediate the undercarriages, which units may be integrated with each other, and a hydraulic jack for the frame operable to relieve the track rails of the machine weight.
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 supporting a chassis capable of housing operating personnel,
- (b) two undercarriages spaced from each other along the track and supporting the frame thereon, the frame defining an upwardly recessed operating space intermediate the undercarriages,
- (c) a hydraulically driven flash butt welding device for welding the abutting rail section ends of a selected one of the rails, the welding device being mounted on the frame in the operating space intermediate the undercarriages,
- (d) a hydraulically driven weld burr removal device mounted on the frame and extending into the operating space intermediate the undercarriages, and
- (e) a support means for the frame operable to relieve the track rails of the machine weight.
