Abstract
A switch device including a switch rail (12), the switch device having at least one stock rail (14), a junction rail (32) and a switch rail support (16), and the switch rail and the connecting rail being interconnected by a weld joint (34). The switch rail support (16) includes a through-opening (36) or a recess beneath the weld joint, the width of the through-opening or the recess being wider than the width of the switch rail (12). Furthermore, the length of the through-opening or the recess allows the junction rail (32) to connect to switch rails of the same or different lengths.
Claims11
A switch device comprising:
- a tongue blade, a stock rail, a connecting rail, and a tongue blade support,
- wherein the tongue blade and the connecting rail are connected to each other via a weld joint,
- wherein a lower side of the tongue blade support borders on a hollow space, and below the weld joint comprises a through opening passing into the hollow space, or
- wherein the switch device possesses a cut-out below the weld joint in the tongue blade support,
- wherein the width of the through opening or cut-out is greater than the width of the tongue blade, and the through opening or the cut-out possesses a length that facilitates joining the connecting rail with tongue blades of equal or different lengths.
A method for replacing a tongue blade in a switch device having at least one stock rail, a connecting rail, and a tongue blade support, wherein the tongue blade and the connecting rail are connected to each other by forming a weld joint by means of welding, the method comprising:
- providing a switch device wherein a lower side of the tongue blade support is bordered by a hollow space, and in the area of the weld joint comprises a through opening that passes into the hollow space, or wherein a cut-out is embodied below the weld joint in the tongue blade support, wherein the width of the through opening or cut-out is greater than the width of the tongue blade and the through opening or cut-out possesses a length that allows separating cuts between the connecting rail and tongue blades of equal or different lengths,
- making a separating cut through the weld joint, or making a separating cut adjacent to the weld joint in the connecting rail,
- removing the tongue blade, and then
- welding the connecting rail to a new tongue blade,
- wherein, when the separating cut extends at a distance from the previous weld joint, the new tongue blade to be connected to the connecting rail will be longer than the replaced tongue blade by the distance between the previous joint weld and the separating cut.
