Problems solved by technology

[0002] Rail vehicles operating in cold and sandy areas will inevitably encounter the problem of easy accumulation of ice, snow and sand on the exposed parts of the bogie, which will cause abnormal wear of the brake disc on the bogie and the action of the brake caliper Defects and other faults, and the accumulated ice falling off will damage the bogie and its upper parts, seriously affecting the safety of the vehicle
At present, there is no effective way to solve the problem of ice and snow accumulation in the braking system in rail vehicles such as EMUs, and it mainly relies on manual removal, which wastes time and energy

Embodiment Construction

[0021] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0022] Such as figure 1 As shown, the present invention provides a kind of rail vehicle diversion snow prevention device, comprises bogie 1, is provided with equipment compartment 2 in other space under the vehicle other than bogie 1, is used for installing equipment under the vehicle, and equipment compartment 2 is opposite to the vehicle under the vehicle. The equipment plays a better protective role.

[0023] The equipment compartment 2 is surrounded by the bottom plate 3 and the skirt plates 4 on both sides. At the position where the bogie 1 is installed, the bottom plate 3 of the equipment compartment 2 will be sunken upwards to avoid the bogie 1, leaving space for the bogie 1. Here The bottom plate 3 at is composed of end plates 5 and top plates 6 at the front and rear ends along the running direction of the vehicle. When the vehicle is ...

Abstract

The invention relates to a flow guide snow-drift control device for a rail vehicle. The snow-drift control device comprises a steering frame and an equipment compartment bottom plate surrounding the periphery of the steering frame, wherein an air guide sleeve protruding out towards the direction of the steering frame is arranged on each of the end plates of the front end and the rear end of the equipment compartment bottom plate in the moving direction of the vehicle. According to the flow guide snow-drift control device for the rail vehicle, the aerodynamic principle is fully utilized, and through the arrangement of the air guide sleeves at the steering frame, the air flow field in the steering frame area is improved, the separation of snow from air flow is improved, the accumulation of ice in the steering frame area is reduced, the damage to the steering frame and parts of the steering frame, caused by the falling off of ice blocks can be reduced, and high safety and reliability in operation of the steering frame and the entire vehicle can be ensured.

Description

technical field [0001] The invention relates to a rail vehicle diversion and snow prevention device suitable for operation in high cold and high wind and sand regions, and belongs to the technical field of rail vehicle manufacturing. Background technique [0002] Rail vehicles operating in cold and sandy areas will inevitably encounter the problem of easy accumulation of ice, snow and sand on the exposed parts of the bogie, which will cause abnormal wear of the brake disc on the bogie and the action of the brake caliper Defects and other faults, and the accumulated ice falling off will damage the bogie and its upper parts, seriously affecting the safety of the vehicle. At present, there is no effective way to solve the problem of ice and snow accumulation in the braking system in rail vehicles such as EMUs, and it mainly relies on manual removal, which wastes time and effort. Contents of the invention [0003] The main purpose of the present invention is to solve the abov...
