Abstract
A mobile apparatus for laying railway track comprises a car running on the rails and a carrier frame with a track on which a power-driven trolley is mounted. The trolley includes a beam for carrying and laying an assembled section of the railway track including rails fastened to ties. A vertically and transversely adjustable flash butt welding machine is arranged below the carrier frame and in the region of the region of the forward end of the car for welding the rails of the assembled railway track section laid by the beam to the rails on the railway track whereon the car is mounted. Associated with the welding machine are devices for removing the welding bead resulting from the flash butt welding of the rails to each other.
Claims5
A mobile apparatus for laying railway track including rails fastened to ties defining cribs therebetween, which comprises
- (a) a car mounted for mobility on the rails of the railway track in an operating direction, the car having a forward end,
- (b) a carrier frame having
- (1) a track and
- (2) a power-driven trolley mounted on the carrier frame track, the trolley including a beam for carrying and laying an assembled section of the railway track including rails fastened to ties,
- (c) a vertically and transversely adjustable flash butt welding device below the carrier frame and in the region of the forward end of the car for welding the rails of the assembled railway track section laid by the beam to the rails of the railway track whereon the car is mounted,
- (d) means associated with the flash butt welding device for removing the welding bead resulting from the flash butt welding of the rails to each other,
- (e) an overhang beam mounted on the forward end of the car and projecting forwardly therefrom,
- (f) power drive means for moving the beam vertically, transversely and in the direction of the railway track,
- (1) the flash butt welding device being mounted on the overhang beam for selective operation in the range of one of the rails of the railway track upon movement of the beam, and
- (g) additional power drive means for positioning the welding bead removing means relative to the flash butt welding device and independently thereof,
- (1) the welding bead removing means including a bead removing device associated with each of the rails.
