RU94002527A - Device to suspend contact system overhead switch conductors - Google Patents

Abstract

FIELD: railway contact system. SUBSTANCE: device has two branches of carrier cables 1 and 2, carrier cable fastening clamp 3, flexible springs stays 4 and wire 5 hinge connected through clamps 6 at both sides from cross joint to carries cables 1, 2 and connected by droppers 1 with contact wires 8 and 9 by cross strip 10. Carcass insert is placed in springing wire 5 before zone of picking. Lower parallel guide rods 11 with half-rings on ends are of C-shaped and are rigidly interconnected by upper corner rod 12 through holes on ends of its web by bolt clamps 13 and by stays 4 through clamps 6 are connected to adjacent carrier cables 1 and 2 at one end and only to one carrier cable 1 or 2 at other end. Guide rods 11, through sliding shackles with polymeric members, clamps 15 and link droppers 7 are connected with branches of contact wires 8 and 9 different factory and temperature length for independent displacement relative to each other at maximum temperature variations with provision of preset length of droppers 7 and height of suspension of contact wires 8 and 9 in zone of their picking by current collector at high speed traffic. EFFECT: improved reliability of suspension. 3 dwg

Claims (1)

The inventive device for hanging wires of an air arrow of a contact network with the aim of increasing the reliability of a suspension of wires contains branches of load-bearing cables, clamps of their fastening, flexible suspension springs and wires, pivotally fastened on both sides from the intersection to the cables and strings with contact wires, fastened cross overlay. At the same time, in the suspension cable in front of the pickup zone, it is equipped with a frame insert, in which the lower parallel guide rods with half rings at the ends are C-shaped and rigidly fastened to each other by the upper corner rod through the hole at the ends of its shelf with bolt clamps, guy wires through the clamps are figuratively connected to adjacent load-bearing cables from one end and only to one load-bearing cable of the other end. Guide rods are connected through clamps with polymer elements moving along them, clamps and strings connected to the branches of contact wires of different construction and temperature lengths with the possibility of independent longitudinal movement at maximum temperature changes while maintaining a given string length and level of contact wire suspension height in the zone of their pickup by the current collector during high-speed movement.
