Safeguarding system for an emergency fish-plate connector

Abstract

A safeguarding system for an emergency fish-plate connector is fastened to a rail base of the rail and has a distance measuring device for supplying a measuring value registering a distance a between the emergency fish-plate connector and the safeguarding system. For transmission of the detected measuring values and of an identifying signalenabling a locally unambiguous correlation of the emergency fish-plate connector with regard to the trackto a control station, the safeguarding system is equipped with a radio device.

Claims

1. A safeguarding system for an emergency fish-plate connector for temporarily connecting two successive rails of a track, the emergency fish-plate connector including a respective fish-plate arranged on each side of the corresponding rail and a clamping device pressing the fish-plates onto the rail, the safeguarding system comprising: a) a distance measuring device fastened to a rail base of the rail, said distance measuring device registering a distance a between the emergency fish-plate connector and the safeguarding system, and supplying a measuring value representing the distance a between the emergency fish-plate connector and the safeguarding system; b) a radio device connected to said distance measuring device and configured for transmitting the detected measuring values and an identifying signal enabling a locally unambiguous correlation of the emergency fish-plate connector with regard to the track to a control station.

2. The safeguarding system according to claim 1, wherein the emergency fish-plate connector is spaced from the safeguarding system with regard to a longitudinal direction of the rail.

Description

BRIEF DESCRIPTION OF THE DRAWING

(1) The sole FIGURE of the drawing is a partial side view of two rails and a connecting fish-plate.

DESCRIPTION OF THE INVENTION

(2) An emergency fish-plate connector 1 is provided for establishing a temporary connection of two successive rails 2 of a track 11 and comprises on each side of the rails 2 a fish-plate 4, bridging a rail gap 3, and clamping devices 5 pressing the fish-plates to the rails 2. Said clamping devices 5 are fixed with a pre-defined torque by screw connections, not further shown. (Details are known from DE 202005007077.7 U).

(3) Adjoining the emergency fish-plate connector 1 with regard to a longitudinal direction 6 of the rail, a safeguarding system 7 is fastened by means of a screw connection 8 to a rail base 9 of the rail 2. Said safeguarding system 7spaced from the emergency fish-plate connector 1 in the present embodimenthas a distance measuring device 10 for supplying a measuring value registering a distance a between the emergency fish-plate connector 1 and the safeguarding system 7.

(4) For transmission of the detected measuring values and of an identifying signalenabling a locally unambiguous correlation of the emergency fish-plate connector 1 with regard to the track 11to a central control station (not shown) of a railway administration, the safeguarding system 7 is equipped with a radio device 12. Additionally, the safeguarding system 7 is equipped with an acceleration sensor 13 for recording measuring values registering vibrations.
