DEVICE FOR MOUNTING ELASTIC stock rail and supporting the wisecracking In railway switches

摘要

The invention relates to the upper structure of railway track and comes to attachment of the frame rails and wits in railway turnouts. A device for the elastic fastening the stock rail and the bearing tongue in railway turnouts comprises a support pad (1) for placing thereon the stock rail (2), wherein (1) the outer side of the stock rail (2) is formed bead (3) mounted on it by means of fasteners (4) the terminal (5) and the inner side of the stock rail (2) installed airbag (6) for supporting the tongue (7), made with a protrusion (8) and the resilient holder (9) which front part rests on the flange (10) of the stock rail (2) and the middle part resting in ag ood sort protrusion (8) cushions (6). According to the utility model, the pillow (6) is provided with internal through a longitudinal cavity (11) within which is mounted a resilient retainer (9) formed as a plate and made of elastic steel with a transverse radius bend from bottom to top in the form of transverse corrugations (12) rear projection (8) cushion (6) is designed as a transverse rib on the top wall (13) of the longitudinal cavity (11) cushions (6), and in the side walls (14) cushions (6) are aligned transverse slots (15) through which omitted shaped wedging element (16) adapted Cl -sighted front portion (17) and the recess (18) in the middle part, wherein the elastic deformation within the rear fixed part of the elastic carrier (9) by bending the transverse corrugation (12). Technical result: improved operational reliability of the device. 1 bp f-ly; 5 yl.
