Abstract

The utility model belongs to an anti-freezing device of a railway passenger train door, comprising a passenger train door on a passenger train carriage and a lower slide way. A blower fan is arranged in the carriage, and a hot air chamber connected with the air outlet of the blower fan is provided with an electric heater, and a flat air channel connected with the outlet of the hot air chamber is fixedly arranged at the lower part of the passenger train door. The flat air channel is parallel with the lower slide way of the passenger train door. Air blowing openings uniformly arranged on the flat air channel are straightly opposite to the lower slide way, and air screens are uniformly arranged in the flat air channel. The hot air blown from the hot air chamber can prevent the lower slide way of the passenger train door to freeze, and therefore, the opening and closing of the passenger train door is flexible, which is convenient for passengers to get on and out. The service life of the passenger train door is extended. The freezing problem of the lower part of the passenger train door and the lower slide way is completely solved.

Description

The defroster of passenger vehicle door

The utility model belongs to the defroster of passenger train door.

At present, along with improving constantly of China railways passenger vehicle class, rapid widespread use stopping sliding door, the double deck passenger car door adopts big sliding door, is convenient to passenger's boarding.But the train that above-mentioned passenger vehicle door is installed is when north cold area moves, and the outer temperature fall of car is to subzero ten degree, and the glide path of passenger vehicle door begins to freeze.This is because the passenger vehicle indoor/outdoor temperature-difference is big, passenger vehicle indoor air temperature height, high humidity, and the aqueous vapor in the room air congeals into ice, and, build-ups ice at the glide path place at last to dirty along the door inwall, causes the passenger vehicle door to open, and gets on or off the bus to the passenger and brings serious inconvenience.When temperature reduced again, the bottom of whole car door and glide path and car body freeze was in the same place.Both influenced the passenger and got on or off the bus, again because of de-icing work causes device damage, every train warehouse-in, each car all will keep in repair the passenger vehicle door, and the time grown and cause the passenger vehicle door to repair, brought serious difficulty and inconvenient for operation work.

The purpose of this utility model is to provide a kind of defroster of passenger vehicle door, the passenger train of cold district operation can prevent that the glide path of passenger vehicle door from freezing in the winter time, make the switch of passenger vehicle door flexible, make things convenient for the passenger to get on or off the bus, prolong the service life of passenger vehicle door, significantly reduced maintenance work the passenger vehicle door.

The utility model is achieved in that a kind of defroster of passenger vehicle door, comprise passenger vehicle door and glide path on the passenger vehicle railway carriage, blower fan is installed in railway carriage, the indoor electric heater that is installed with of its air outlet bonded assembly hot blast, the flat air channel of outlet bonded assembly of hot blast chamber is fixedly mounted on the bottom of passenger vehicle door, and parallel with the glide path of passenger vehicle door, blowing mouth uniform on the flat air channel is directly to glide path, uniform air baffle in flat air channel.

Because uniform the blowing mouth in flat air channel on the position that the glide path of passenger vehicle door parallels, the electric heater of cold wind in the hot blast chamber that is blown out by blower fan is heated into hot blast, blow to the glide path of passenger vehicle door from the uniform blowing mouth in flat air channel, make the bottom and the glide path of passenger vehicle door keep higher temperature, can not freeze at the glide path place along the condensate water that passenger vehicle door inwall flows downward, thereby the problem that passenger vehicle student portion and glide path freeze is solved.The cold wind that the electric heater heating blower blows out, heating properties is reliable, and glide path work is flexible, and the passenger vehicle door switch is convenient.The utility model makes the train in the north cold area operation use stopping sliding door and big sliding door that the failure-free assurance is provided.
