Device for preventing snow from being accumulated at bogie region of high-speed train

Abstract

The invention discloses a device for preventing snow from being accumulated at a bogie region of a high-speed train. The device for preventing snow from being accumulated comprises two executing mechanisms, wherein each executing mechanism comprises a flow guiding plate, mounting bases, pin shafts, double-acting air cylinders, flow guiding plate pin shafts and flow guiding plate bases; one side facing to a bogie, of each flow guiding plate, is connected with the corresponding double-acting air cylinder, and the other side of the flow guiding plate is connected with a chassis of the train; one end of each double-acting air cylinder is connected with a train body, and the other end of each double-acting air cylinder is connected to the corresponding flow guiding plate. Vehicle-mounted high pressure air is adopted as control power, and the double-acting air cylinders are controlled by double-acting electromagnetic valves. The flow guiding plates can deform as needed. When the train runs forwards, the flow guiding plate in front of the bogie is unfolded, and the rear flow guiding plate is folded, so that the bottom air flow does not pass through the bogie region. When the train runs backwards, the two flow guiding plates take actions, namely the folded flow guiding plate is unfolded, and the unfolded flow guiding plate is stretched.

Description

technical field [0001] The invention relates to a mechanical 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, then freeze into ice, reciprocate, and finally form larger ice cubes on the bogie. The ice cubes change the dynamic characteristics of the bogie, and even restrict the movement of the bogie. Can cause serious derailment and other major accidents. [0003] Some car bodies are equipped with fixed rubber capsules to improve the flow field structure in the bogie area. [0004] The above structure improves the entry conditions and reduces the amount of snow entering ...

Problems solved by technology

[0004] The above structure improves the entry conditions and reduces the amount of snow entering the bogie area, but the symmetrical structure at the tail will pocket the snow and eventually cause the entire bogie to accumulate snow
