Problems solved by technology

[0002] At present, domestically, the "Special Tunnel 0001" and "Three Standard Tunnel 0012" tunnels adopt horizontal suspension catenary cables. When the tunnel pulley swings to a certain angle when the curve is curved, the catenary cables move and wear down on the lower edge of the pulley bracket when the temperature changes. Over time, the catenary cable will be worn out, causing traffic accidents
The wire is connected to the positioning tube at the positioning point with a silicone rubber or porcelain insulator, and a supporter is installed on the positioning tube for positioning. The weight of the entire insulator and the positioning tube is borne by the wire at the positioning point, causing the wire to have a hard point at the position, and the pantograph cannot Smooth passage, poor flow conditions

Embodiment Construction

[0015] Such as figure 1 As shown, the catenary suspension device includes a catenary suspension base 1, an anti-corrosion adjustment bolt 2, a silicon rubber insulator 3, a pulley bracket 4, a pestle ring rod 5, and a tunnel pulley 6. The catenary cable suspension base 1 is a U-shaped structure, welded on the bottom plate, and fixed on the tunnel wall symmetrically along the top of the tunnel through chemical anchor bolts. One end of the ring rod 5 is connected with the round holes on the left and right catenary suspension bases 1 respectively, and the other end of the anti-corrosion adjustment bolt 2 and the pestle ring rod 5 are respectively connected with the pulley bracket 4 in the middle through the left and right silicon rubber insulators 3 . When the anti-corrosion adjustment bolt 2 is connected with the round hole of the catenary suspension base 1, the height of the catenary can be adjusted by selecting round holes of different heights; simultaneously tighten the silic...

Abstract

The invention relates to single track tunnel overall positioning equipment used in an electrified railway contact system, which is characterized by comprising a catenary wire hanging pedestal (1), ananti-corrosion adjusting bolt (2), a silicon rubber isolator (3), a pulley bracket (4), a ball-socket bar (5), a tunnel pulley (6) and a contact wire positioning device, wherein the pulley bracket (4)drives the tunnel pulley (6) to rotate around an ear ring (19) at 360 degrees, and a V-shaped suspension is arranged between a flat cantilever (10) and a catenary wire (17). The single track tunnel overall positioning equipment prevents abrasion, reduces hard points at a positioning point, allows a pantograph to pass through smoothly and improves the current collection effect.

Description

technical field [0001] The invention relates to a device used in an electrified railway tunnel catenary, specifically an overall positioning device for a single-line tunnel used for contact line positioning and catenary suspension in a single-line tunnel catenary system. Background technique [0002] At present, domestically, the "Special Tunnel 0001" and "Three Standard Tunnel 0012" tunnels adopt horizontal suspension catenary cables. When the tunnel pulley swings to a certain angle when the curve is curved, the catenary cables move and wear down on the lower edge of the pulley bracket when the temperature changes. Over time, the catenary cables are worn out, causing traffic accidents. The wire is connected to the positioning tube at the positioning point with a silicone rubber or porcelain insulator, and a supporter is installed on the positioning tube for positioning. The weight of the entire insulator and the positioning tube is borne by the wire at the positioning point...
