Abstract

The invention provides a railroad bridge air-guide handrail which is used for reducing the influence of crosswind on a high-speed locomotive on a bridge girder and ensuring the high-speed safe operation of the locomotive. The railroad bridge air-guide handrail comprises erection supports (20) and baffle guide plates (10), wherein the erection supports (20) are arranged on two sides of a girder body at intervals and are fixedly connected with the girder body; the baffle guide plates (10) are fixedly connected with the erection supports (20) and are provided with vertical air blocking surfaces (11) and air guide surfaces (12) positioned at the upper parts of the air blocking surfaces (11) and inclining outwards; vent holes (15) are distributed in the air blocking surfaces (11) and the air guide surfaces (12).

Description

technical field [0001] The invention relates to railway bridges, in particular to a wind guiding and wind-shielding device for railway bridges to reduce the influence of cross winds on high-speed locomotives and ensure the high-speed and safe operation of trains. Background technique [0002] In order to prevent train overturning or derailing accidents caused by strong cross winds in railway wind areas, reduce the aerodynamic force of railway vehicles under the action of cross winds, and ensure that trains can run normally and safely under strong wind conditions, the main effective measures generally adopted at home and abroad are Build a windshield or a windshield in the windy area. According to the situation of strong wind and sand in the windy area of ​​the railway in the western gravel desert area such as the Lanxin Line, at present, there are basically three types of airtight windshield walls used in these railway windy areas in China: earth embankment type, concrete re...
