Air channel, the return air box is arranged in drivers' cab roof close to the position of headwall, and the return air box includes a housing, in the shell
Air inlet and exhaust outlet are provided with body, the air inlet is connected with the drivers' cab, the exhaust outlet passes through the connection air channel
Connected with the return air inlet of air-conditioner set indoor set.The structure setting in roof close to the position of headwall, by the return air of drivers' cab with
The return air inlet connection of air-conditioner set.
But when an emergency happens, the air-conditioner set of overall vehicle is to close, drivers' cab lack auxiliary return air and
Cause that air is smooth, even partial closure phenomenon, so that enough fresh airs can not be added into drivers' cab.
The content of the invention
Railway vehicle cab described in the utility model aids in air channel, and purpose of design is to solve the above problems and not
Foot is there is provided a kind of guest room and the direct-connected auxiliary duct installing structure of drivers' cab insertion, and what will in real time be supplied to guest room is pure and fresh
Air, drivers' cab is delivered to by an auxiliary piping.Once the emergencies such as generation air conditioner in cab failure, can be by described auxiliary
Air channel is helped to continue to provide the air of smooth homogeneous to drivers' cab.
To realize above-mentioned purpose of design, the railway vehicle cab auxiliary air channel is integrally provided in cab roof and outer
Between side body, include auxiliary wind box, be connected to the auxiliary valve of auxiliary wind box side, connect the soft of drivers' cab auxiliary air-outlet
Aid in discharge pipe, connect the soft auxiliary air supply pipe of guest room.
Even if as described above, be ensure drivers' cab occur air-conditioning have a power failure with failure conditions under ventilation condition, guest room with
One group of auxiliary air return pipeline is connected between drivers' cab, to meet unobstructed and barotropic equilibrium the use demand of internal gas flow.
While drivers' cab return air requirement is met, for the limitation condition such as drivers' cab top structure is compact, space is limited,
The drivers' cab auxiliary air channel is independently installed, and the airduct being made of soft material, and auxiliary wind box and auxiliary valve are pacified
It is placed on top plate or car body.
When an emergency happens, the moving vane of auxiliary valve starts, and forcibly imports the fresh air in guest room
Drivers' cab, so as to open auxiliary air supply pattern.
Further to adjust the internal-external temperature difference in the case of emergency ventilation, can by it is described auxiliary wind box outside be provided with to
Few one layer of heat preservation layer.
The auxiliary wind box is connected by L-type bearing and is fixed on car body.
Further improve and be, the soft auxiliary discharge pipe is connected by turbine pipe clamp with auxiliary wind box, uses turbine pipe
Folder is attached, and efficiently and easily can be safeguarded and be overhauled.
Based on identical design principle, the outside of the soft auxiliary discharge pipe is provided with least one layer of heat-insulation layer.
The soft auxiliary air supply pipe is connected by turbine pipe clamp with auxiliary valve.
The soft auxiliary air supply pipe, is provided with least one layer of heat-insulation layer outside it.
To sum up content, the utility model, which is had the advantage that with beneficial effect, is, with the ventilation being connected in the past with air-conditioning device
Pipeline is compared, and structure is more simple compact, and collectivity is strong, and repair and maintenance opens convenient and swift, the features such as auxiliary air supply is smooth.
