Abstract
A welding unit for welding rails of a track includes a first sub-unit which is displaceable on unit guides in a rail longitudinal direction relative to a second sub-unit by using displacement cylinders. Each sub-unit includes clamping cylinders disposed underneath the unit guides and coupled to clamping jaws for clamping the rails. The two sub-units are connected by the displacement cylinders in that a cylinder body of the respective displacement cylinder is connected to one sub-unit and a piston rod of the respective displacement cylinder is connected to the other sub-unit. Thus, it is not necessary to support the displacement cylinders relative to a transverse beam disposed at the front.
Claims11
A welding unit for welding rails of a track, the welding unit comprising:
- unit guides extending in a rail longitudinal direction;
- clamping jaws for clamping the rails;
- displacement cylinders each having a respective cylinder body and a respective piston rod;
- first and second sub-units, said first sub-unit being displaceable on said unit guides in said rail longitudinal direction relative to said second sub-unit by said displacement cylinders, each of said sub-units including clamping cylinders disposed underneath said unit guides and coupled to said clamping jaws;
- and
- said cylinder body of each displacement cylinder being directly flange-connected to a respective one of said sub-units and said piston rod of each displacement cylinder being directly flange-connected to a respective other of said sub-units, for interconnecting said first and second sub-units.
