Abstract

Railway switches are subjected to a high degree of stress due to the influences of weather and as a result of trains traveling over them. This may result in changes in adjustments and settings made at the time of mounting. In order to permit, in particular in the case of hollow sleepers, simple re-adjustment of a drive rod relative to the cam rods, an attachment element can be connected to an attachment flange by a positive lock, formed by various adjustment keys and a main key, and using locking screws in such a way that fine adjustment by appropriately selecting the arrangement of the adjustment keys is possible. Coarse adjustment is made by an asymmetric arrangement of the bore holes for connecting to a drive rod as well as by selecting one of the two bore holes.

Dependent claims

A device for setting symmetry in

a railway switch system, comprising:
a drive rod;
a cam rod connected to a switch blade of the railway switch system;
a locking device releasably locking said cam rod and said drive rod to one another, with said locking device released, said cam rod and said drive rod being displaceable relative to one another in discrete grid steps, and said locking device being configured to lock said cam rod and said drive rod with a positive lock;
an attachment flange formed as a side attachment and an attachment element connected to said drive rod, said cam rod being fixedly coupled to said attachment flange, said attachment flange and said attachment element being displaceable relative to one another in a first grid and being fixable to one another by said locking device with said positive lock;
and a bearing bolt connecting said drive rod to said attachment element, a second grid being defined by at least two bore holes formed in said attachment element through which said bearing bolt is selectively insertible.
