RU95106238A - Stationary wedge device for holding trains on station tracks - Google Patents

Abstract

FIELD: railway transport. SUBSTANCE: device has resilient wedge arranged inside track gauge. Wedge is formed by two brake blocks, with wedge point towards rolling-on wheelset. Meeting ends of wedge are hinge- secured on first crossmember which is rigidly coupled by end with track rail lines; other ends of wedge adjoin freely the spring beams some ends of which are hinge-secured on second crossmember and others are provided with rollers and rest freely on third crossmember. Cotter controlled by slotted-link mechanism is installed between rollers of spring beams for displacement relative to this crossmember. EFFECT: improved reliability of holding trains on station tracks, provision of failure-free operation of device under any conditions. 1 cl, 3 dwg

The invention relates to railway transport, in particular to means for securing the composition on station tracks. The invention solves the problem of reliable fastening of trains on station tracks and trouble-free operation of the device in any random situations. The device comprises an elastic wedge located inside the track, formed by two brake tires and turned with its tip towards the rolling pair of wheels, while the converging ends of the wedge are pivotally mounted on the first cross member, which their ends are rigidly joined with the rail threads of the path, and the diverging ends of the wedge are freely adjacent to the spring beams, some ends of which are pivotally mounted on the second cross member, while others are provided with rollers, freely rest on the third cross member, on which between the rollers spring springs approx movably mounted with respect to this check crosspiece, controlled by the crank lever mechanism.
