Abstract
The invention relates to a measuring arrangement for monitoring a railway track having rails fastened to sleepers, wherein a fibre optic cable is connected to a measuring device in order to detect a strain acting on a rail. In this, the fibre optic cable is clamped in a detachable manner into at least one rail fastening. In this way, a strain transmitted from the rail via the rail fastening to the sleeper acts directly on the fibre optic cable.
Claims12
A measuring arrangement for monitoring a railway track having rails fastened to sleepers, the arrangement comprising:
- fibre optic cable;
- a measuring device coupled to said fibre optic cable in order to detect a strain acting on a rail,
- at least one rail fastening, wherein the fibre optic cable is clamped in a detachable manner into said at least one rail fastening, wherein the at least one rail fastening includes a lateral guide for lateral support of the rail, and that the clamped fibre optic cable rests against the lateral guide.
A method for creating a measuring arrangement for monitoring a railway track having rails fastened to sleepers, wherein a fibre optic cable is connected to a measuring device in order to detect a strain acting on a rail, wherein the fibre optic cable is clamped in a detachable manner into at least one rail fastening wherein, the method comprises:
- laying the rail on the sleepers during new track construction or track renewal, by means of a track maintenance machine, that—before, after or during this step there is the step of:
- reeling off—the fibre optic cable from a spool arranged on the track maintenance machine and
- positioning the fibre optic cable at respective clamping points, and that the rail is fastened to the sleepers by means of the rail fastenings while simultaneously clamping the fibre optic cable.
A measuring arrangement for monitoring a railway track having rails fastened to sleepers by means of rail fastenings, comprising:
- a fibre optic cable
- a measuring device wherein the fibre optic cable is coupled to the measuring device in order to detect a strain acting on a rail, wherein the fibre optic cable is clamped in a detachable manner into at least one of the rail fastenings, wherein in the clamped state, the fibre optic cable is pressed against a surface of the at least one rail fastening.
