Embodiment Construction

[0033] figure 1 A top view of a device 1 for welding rail joints 2 of installed rails 3 is shown, said device comprising two rail clamping devices 5 spaced apart from each other in the rail longitudinal direction 4, said rail clamping devices One rail end 6 is fastened in each case and connected to one another via two pressure rods 7 . A first hydraulic cylinder 8 is assigned to each pressure transmission rod 7 in order to press the two rail ends 6 apart until there is no longer an overlap 9 . The pressure transmission rods 7 each have a spring nut 10 in order to align the two rail clamping devices 5 precisely with one another.

[0034] The corresponding rail clamping device 5 is simply moved from above onto the associated rail end 6 and secured against displacement in the rail longitudinal direction 4 by means of wedges 11 each acting on the rail web 12 . The rail clamping device 5 arranged on the rail end 6 to be displaced has fastening eyelets 13 on both sides for accommo...

Abstract

The invention relates to a device (1) for welding rail joints (2) of rails (3), said device comprising two joints spaced apart from each other in the longitudinal direction of the rail (4) and connected to each other by means of pressure transmission rods (7). Attached rail clamping device (5) to squeeze the rail ends (6) apart prior to welding. It is provided here that at least one rail clamping device (5) is coupled to the transverse displacement device (14) in order to align the rail ends (6) after the separation.

Description

technical field [0001] The invention relates to a device for welding rail joints of rails, said device comprising two rail clamping devices spaced apart from each other in the longitudinal direction of the rails and connected to each other by means of pressure transfer bars, so that the ends of the rails are welded before welding squeezed apart. Furthermore, the invention relates to a method for welding rail joints by means of such a device. Background technique [0002] Mobile welding units are increasingly used to weld two rails of a track. Unlike in the older thermite welding, here the rail ends are fused without the addition of foreign material. However, this results in a slight rail shortening which has to be compensated. [0003] Typically, rail sections are first welded with loose rail fasteners. Then, during the final welding, the rail receives its preset longitudinal stress for the current ambient temperature. So-called rail pulling devices (DE 20 2015 006 320 ...
