<p>The present invention relates to a method and a device for detecting derailment adapted to a vehicle guided by a guidance system including at least one guide member interacting with a railhead (13) of a rail (1) used to guide the guided vehicle, characterized in that said device includes: - a clamp (4) having a bottom jaw (41) that, in closed position, closely and contactlessly surrounds the railhead (13) of the rail (1), and that opens when the jaw (41) thereof opens in the event of a loss of interaction between the guide member and the rail (1), said opening being caused by an at least partial movement of said railhead (13) outside the jaw (41), at least one top rod (421, 422) of the clamp (4) enabling the opening of the jaw (41) to be transmitted mechanically to at least one switch (51, 52), - said switch (51, 52) having two configurations, a nominal configuration corresponding to the closed position of the clamp (4) when rail position is correct, and a warning configuration caused by the mechanical transmission of the opening of the jaw (41) to the switch (51, 52), said warning configuration being able to actuate at least one safety system of the guided vehicle.</p> |
