US 10,654,496 B2 · Railway vehicle derailment detection method and device

Abstract

A transmission line 5 configured to be broken when it comes into contact with a rail 4 is installed on a disengagement prevention guide 1 attached to an axle box 3 of a railway vehicle. One end 5a and the other end 5b of the transmission line 5 are connected to a determination unit 6 to monitor continuity of the transmission line 5. In the event of a derailment, the determination unit 6 determines that a derailment has occurred when the disengagement prevention guide 1 makes contact with the rail 4 and the transmission line 5 breaks, thereby interrupting the continuity of the transmission line 5. This arrangement allows an accurate detection of a derailment, so as to prevent a railway vehicle from traveling when its wheels have become disengaged from a rail without an operator being aware of it, thus improving safety after the derailment occurs.

Claims4

Dependent claims

A railway vehicle derailment detection method for a railway vehicle traveling on a rail, comprising:

installing a derailment detection member disposed at a position on the railway vehicle that makes contact with a rail or a ground-based equipment installed on an inner side of a pair of rails, and that breaks due to direct contact with the rail or the ground-based equipment in event of a derailment;
and
determining that a derailment has occurred by detecting that the derailment detection member has been broken due to direct contact with the rail or the ground-based equipment;
wherein breaking of the derailment detection member prevents a railway vehicle from traveling when wheels of the railway vehicle become disengaged from the rail without knowledge of an operator of the railway vehicle.

A railway vehicle derailment detection device for a railway vehicle traveling on a rail, comprising:

a derailment detection member that is installed in a portion of the railway vehicle, the derailment detection member being configured to be broken when a portion of the railway vehicle comes in direct contact with a rail or a ground-based equipment installed on an inner side of a pair of rails;
and
a device that determines that a derailment has occurred by detecting that the derailment detection member has been broken when the portion of the railway vehicle comes in direct contact with the rail or the ground-based equipment;
wherein breaking of the derailment detection member prevents a railway vehicle from traveling when wheels of the railway vehicle become disengaged from the rail without knowledge of an operator of the railway vehicle.
