METHOD OF DETECTING HAZARDOUS PLACE WITH EXCESSIVE LONGITUDINAL COMPRESSIVE FORCE CAUSING STABILITY LOSS OF CONTINUOUS TRACK Russian patent published in 2017 - IPC E01B11/00 E01B35/06 B61K9/08 

FIELD: measuring equipment.

SUBSTANCE: when monitoring the railway track axis position in the diagram by the road measuring device (for example, a traveling car), at the beginning of the summer season (April-May, depending on the climatic zone), the rail bending values of a continuous track, not yet dangerous for the train movement, are fixed in the diagram. These original diagrams are retained until the diagrams are obtained in the next measuring device way. The subsequent diagrams are superimposed on the previous ones, combining them in a linear coordinate (abscissa), the difference in the ordinates is determined at the maximum boom position, this difference is divided by the elapsed time between the measuring device ways, the boom growth rate is determined, and thus a dangerous place is detected with a dangerous rate of the unevenness boom value change.

EFFECT: dangerous place with excessive longitudinal compressive force in rail lashes is detected in advance.
