Snow accumulation preventing device for train bogie area

Abstract

The invention discloses a snow accumulation preventing device for a train bogie area. The snow accumulation preventing device for the train bogie area comprises a first executing mechanism and a second executing mechanism, whose acting sequences are determined according to a train running direction, wherein the first executing mechanism and the second executing mechanism are respectively mounted on a front end plate and a rear end plate of a train underframe; a bogie is positioned between the first executing mechanism and the second executing mechanism; the first executing mechanism comprises a first retractable wind deflector; the second executing mechanism comprises a second retractable wind deflector; and the first wind deflector, close to the train advancing direction, and the second wind deflector, far away from the train advancing direction, are arranged to have the following matching relation that the second wind deflector is in a retracted and closed state towards the train underframe while the first wind deflector is in an extended and opened state. According to the invention, snow accumulation can be avoided in the operation of the train bogie so that the dynamic performance of the bogie is ensured, the safety of the train during running in the snow is enhanced and the transporting efficiency of the train during running in the snow is increased.

Description

technical field [0001] The invention relates to a train auxiliary functional matching device, in particular to a snow prevention device capable of preventing snow accumulation in the bogie region of a high-speed train during heavy snow operation in winter. Background technique [0002] When high-speed trains are running in heavy snow weather in alpine regions, the snow on the line will roll up due to the influence of the turbulence in the bogie area and accumulate on the bogie, and the snow will generate heat on the bogie. Under the action of braking, etc., it will melt into water, and then freeze into ice. After the reciprocating action, finally a large ice cube will be formed on the bogie. The ice cube changes the dynamic characteristics of the bogie, and even restricts the movement of the bogie. Major accidents such as serious derailment may result. [0003] At present, most high-speed trains are not equipped with anti-snow and icing devices. When running in snowy weathe...

AI Technical Summary

Problems solved by technology

Some high-speed train bodies are equipped with rubber capsules on the end plates of the bogie area to improve the flow field structure in the bogie area. This structure improves the entrance conditions to a certain extent and reduces the amount of snow entering the bogie area. There is a certain anti-snow function in actual operation, but for high-speed trains with long distances and large crossings running in heavy snow for a long time, the symmetrical structure of the tail will pocket snow, and eventually there will be serious snow accumulation in the bogie area
