FIELD: electrified transport. ^ SUBSTANCE: invention is designed for mounting of bracket-insulator on ties for suspending contact rail both in tunnels and on ground sections, mainly in places of leaks, watered places and places of higher "rail-lining: potential, for instance, in underground railways for electric trains. Proposed bracket of contact rail consists of post and suspension unit made in form of two hold-downs with mating part turned towards each other, getting into one another and interconnected by fastener having profile of contact rail head from inner side. Mating part of hold-down is made integral with post. Post contains vertical part made of H-section changing from top into matting one for clamping horizontal part of H-section with guide projection and with protective load-bearing web at top changing at bottom into support in form of platform with dowel. Hold-down is made in form of angle plate with vertical part and horizontal part provided with through slot arranged from top. Holder and projection made in form of profile of contact rail head are arranged, respectively from bottom of horizontal part of post and horizontal part of hold-down. Bracket is furnished additionally with base made in form of parallelepiped with through hole for dowel at one end along axis, and support platform with through holes at other end. ^ EFFECT: improved manufacturability, convenience of mounting of contact rail, facilitated assembling and operation, prevention emergency situations and increased service life of construction. ^ 16 cl, 7 dwg |
