Abstract

FIELD: energy.

SUBSTANCE: invention relates to power supply lines contacting current collectors of vehicles. Aerial crossing has device for simultaneous lifting of contact wires at beginning of control zone. Lifting device consists of connecting element (1) rigidly attached to carrying cable (2) compensated overhead catenary with main lever (4) and rigid strings (6), (7). Connecting element (1) is attached to carrying cable (3) of adjoining track with possibility of back-and-forth movements. Angle (8) is rigidly attached to connecting element (1) by means of bolt (9). To angle piece (8) are attached by means of bolts (10), (11) of bracket (12), (13), equipped with rollers with slots, which it runs in bearing cable fixed against dropping of rollers rivets (14), (15). Ends of thrust angle are connected by flexible braces (16), (17) to supporting cable (2), installed at angle of 30-40° to it, and flexible braces (19), (20) with bracket (18) of rigid string (7).

EFFECT: technical result consists in provision of reliable current collection during high-speed movement.

Description

The invention relates to the electrification of railways and can be used in chain contact suspensions.

The purpose of the invention is the creation of an air arrow made by combining a compensated contact suspension on a direct path, providing reliable current collection at speeds of 200-300 km / h, and a half-compensated contact suspension on an adjacent side path at speeds of up to 120 km / h by ensuring the same and simultaneous lifting contact wires of adjacent paths in the pickup zone with the required amount of pressing current collectors up to 30-40 kg.

Known are “air arrows of the contact network of railways” published in the copyright certificate No. 1369939 dated 10/01/1986, utility models No. 18681 dated July 10, 2001 and No. 21043 dated December 20, 2001, made by combining semi-compensated contact suspensions containing and depicted in FIG. 1, a connecting element 1, made in the form of a corner, each end of which is mounted on bearing cables 2, 3 and fixed to it with bolt clamps, the main lever 4, at one end of which a counterweight 5 is mounted with the possibility of movement along the lever, and on the other the strings 6, 7 are pivotally fixed at the end with the possibility of changing their length; it is installed by means of bearings made of bronze on an axis located between two vertical posts rigidly connected to the connecting element in its middle part. Each of the strings is formed of two interconnected rigid elements for regulating up to 25% of its length. The stiff strings are connected at the lower ends to a single or double contact wire without the possibility of or with the possibility of reciprocating movement on flat or round elements fixed by clamps on the contact wires. Plates of insulating material are installed at the bottom of hard strings. The high-speed air arrow, characterized in that in the direction of the direct path it is equipped with a compensated contact suspension (the bearing cable and the contact wire, when changing the temperature, perform translational-return movements of the same magnitude and direction up to 0.7-0.8 m), along the adjacent path - a semi-compensated contact suspension (translational-reciprocal movements up to 0.7-0.8 m, different or equal in magnitude to the contact wire of the compensated contact suspension, only the contact wire performs), to which are not mechanically interconnected, the connecting element 1 is attached to the supporting cable 3 of the adjoining path with the possibility of reciprocating movements, for which, with the help of the bolt 9, the corner 8 is rigidly attached with the brackets 12, 13 attached to it with the bolts 10, 11 equipped with rollers with grooves with which it rests on a support cable, fixed by rivets 14, 15 from falling off the rollers, the ends of the support angle are connected by flexible struts 16, 17 with a support cable 2 installed at an angle of 30-40 ° to it and flexible struts 19 , twenty with the bracket 18 of the stiff string 7, equipped with insulating elements, as a result of which the connecting element 1, rigidly connected with the carrier cable 2 and the reference angle 8, together with the main lever and rigid strings attached to it, perform reciprocating displacements of the same magnitude, remaining at a predetermined position to each other, providing the necessary elasticity of the contact pendants, the position of the contact wires at the same level and reliable current collection at given maximum speeds and increased pressure x current collectors.
