Abstract

The invention discloses a mounting method for an air delivery duct of a conference room of a special railway vehicle. The method comprises the following steps of: fixing a main air duct with an air duct supporting beam; fixing the air duct supporting beam with an aluminum longitudinal beam and hanging iron; mounting a secondary air duct connecting subassembly; fastening and connecting the secondary air duct with the second secondary air way connecting iron through a bolt; mounting a connecting air duct between a secondary air duct air inlet and a main air duct air outlet; fixing an illumination lamp belt at the lower side of the secondary air duct air outlet through the bolt; connecting an end of a side ejection plate with the upper end of the secondary air duct; propping the ejection plate to a horizontal pressure plate inside the secondary air duct; tightly adhering the ejection plate to the secondary air duct horizontal pressure plate; buckling the secondary air duct by one side of the air delivery shield plate through an inserting structure; connecting and fastening the other side of the air delivery shield plate with the secondary air duct through the bolt; and after finishing the mounting of air delivery shield plates at two sides, naturally dropping the ejection plate on the bracket with a warped inner end on the air delivery shield plates. The novel air delivery duct structure provided by the invention has the advantages of advanced mounting method, high assembling precision and higher assembling efficiency.

Description

technical field [0001] The invention relates to a method for installing an air supply duct in a meeting room of a railway special vehicle, and belongs to the technical field of air ducts of an air conditioning system. Background technique [0002] The air-conditioning ventilation channel and air supply form of the conference room of railway special vehicles are arranged according to the special requirements of the car body. Mesh roof has strict requirements on the air supply speed. Generally, the diameter of a single air supply hole is 3-7mm, and high air supply speed is prone to whistling; low air supply speed will result in poor cooling effect. In addition, the number of mesh holes on the top plate is large and the area is large. In order to ensure uniform air supply, there is no dead angle of air supply. There are tens of thousands of ventilation holes on the whole roof plate, the roof plate needs to be cleaned regularly during use, and the maintenance work is heavy. Th...
