Abstract

A kind of EMU aluminum alloy bodywork with condensate water discharging structure, comprise underframe, roof, side wall, headwall, it is characterized in that: four jiaos of vehicle top air conditioner frame arrange draining breach, discharge the condensed water in roof die cavity, interface at side wall and edge beam of underframe arranges drain gutter, for the condensed water that is converged to side wall die cavity by section bar is discharged in interlayer, the drainage channel of UNICOM's die cavity is set in end wall panel bottom, drain gutter is set on headwall, some drain gutters are set, for discharging the condensed water of interlayer on bottom frame floor.The utility model has ensured that in car body die cavity and car, the condensed water inside interlayer can be discharged outside car in time, also can prevent that car body die cavity from entering snow, can prevent that condensed water is by the bursting by freezing of car body aluminium section bar by actv., prevent that vehicle condensed water from bringing destruction to in-built and cable simultaneously.

Description

With the EMU aluminum alloy bodywork of condensate water discharging structure

Technical field

The utility model relates to a kind of car body condensate water discharging structure, especially relates to the anti-control techniques of the whole aluminum alloy bodywork condensed water of EMU in the situation that a kind of temperature difference is large.

Background technology

The high and cold motor train unit of CRH380B type are mainly runed in the Northeast of China, and winter, the vehicle internal and external environment temperature difference was larger, and the garage internal and external environment temperature difference is also larger, cause a large amount of condensed water of the outside and inner generation of car body.At present, according to the operation demand of railway main office, expanded the operational area of these type motor train unit, started directly to stride into from northeast North China, South China's operation, the operation process environment temperature difference is larger, also can cause a large amount of condensed water of the outside and inner generation of car body.Current aluminum alloy bodywork discharge structure is unreasonable, car body die cavity condensed water inner and the inner generation of interlayer cannot be got rid of outside car, and also cannot get rid of outside car after the inner unexpected water inlet of car body die cavity, cause the situation of body profile corrosion and bursting by freezing to rarely have generation, therefore, research and develop the car body of the anti-control techniques of condensed water rational in infrastructure extremely urgent.

Utility model content

The purpose of this utility model is to provide a kind of aluminum alloy bodywork that a large amount of condensed waters that produce inside and outside car body can be discharged in time, the corrosion and the internal unit that prevent car body are impaired, can effectively stop outside sleet to enter the inner ponding icing that forms of car body die cavity simultaneously.

For achieving the above object, the utility model provides a kind of EMU aluminum alloy bodywork with condensate water discharging structure, comprise underframe, roof, side wall, headwall, it is characterized in that: four jiaos of vehicle top air conditioner frame arrange draining breach, discharge the condensed water in roof die cavity, interface at side wall and edge beam of underframe arranges drain gutter, for the condensed water that is converged to side wall die cavity by section bar is discharged in interlayer, the drainage channel of UNICOM's die cavity is set in end wall panel bottom, drain gutter is set on headwall, some drain gutters are set on bottom frame floor, for discharging the condensed water of interlayer.

By vehicle top air conditioner frame four jiaos of the utility model arrange draining breach, discharge the condensed water in roof die cavity, interface at side wall and edge beam of underframe arranges drain gutter, for the condensed water that is converged to side wall die cavity by section bar is discharged in interlayer, discharge outside car by the drain gutter on bottom frame floor again, the drainage channel of UNICOM's die cavity is set in end wall panel bottom, condensed water in die cavity converges to together by drainage channel, then by the drain gutter arranging on headwall, condensed water is discharged outside car, some drain gutters are set on bottom frame floor and discharge the condensed water in interlayer.This aluminum alloy bodywork has ensured that in car body die cavity and car, the condensed water inside interlayer can be discharged outside car in time, also can prevent that car body die cavity from entering snow, can prevent that condensed water is by the bursting by freezing of car body aluminium section bar by actv., prevent that vehicle condensed water from bringing destruction to in-built and cable simultaneously.
