LEVER-SPRING DEVICE (VERSIONS) AND METHOD OF FASTENING RAILWAY STOCK Russian patent published in 2019 - IPC B61K7/06 B61K7/20 B61L3/00 

FIELD: machine building.

SUBSTANCE: invention relates to auxiliary railway equipment. On the railway track there installed is a lever-spring device for fixation of the rail stock, which includes a housing installed between sleepers at equal distance from opposite rails on dead axes fixed in holes of rails necks, with installed in it set of springs, and dual lever, which one arm is common and represents flat stop, made in form of beam, and rigidly fixed on movable axis, and other lever of double lever consists of two L-shaped or Z-shaped stops fixed on opposite ends of same movable axis. Free ends of thrusts are made in the form of cups with antifriction coating and are located at the level of flanges of wheel pairs wheels with possibility of contact with wheelset wheels flanges at passage of train with locomotive. Double lever is made with possibility of free turn at passage of the train in the permitted direction and with possibility of rotation and power contact of the flat thrust with the set of springs at spontaneous departure of the composition in the reverse direction. Device has a sensor for positioning the turning angle of the flat stop, the signal from which is transmitted to the automated workstation of the duty officer, where the actual retention force of the composition is calculated.

EFFECT: disclosed are a lever-spring device (versions) and a method of fastening railway stock.
