Detailed Description
In order to better understand the purpose, structure and function of the present invention, the following describes the air supply structure of the cab with two air ports in further detail with reference to the attached drawings.
Referring to fig. 1 and 2, the double-air-port cab air supply structure is installed above a cab, extends towards two directions in the cab, is provided with air ports above main and auxiliary driver seats and can be independently adjusted at the same time, and comprises a passenger room air duct 4, a transition air duct 3, a cab air supply unit 1, a cab air duct 2 and an adjustable air port 5, wherein installation supports 6 are arranged on two sides of the passenger room air duct 4, the cab air supply unit 1 and the cab air duct 2 and are fixedly connected with a roof.
Referring to fig. 3 to 6, the passenger room air duct 4 supplies air at the end of the passenger room in a side air supply mode, the passenger room air duct 4 adopts a bottomless air duct, the lower side of the passenger room air duct is fixedly connected with the built-in top plate and is sealed by the bottom sealing strip 7, the structure ensures that the bottomless air duct of the passenger room can be conveniently communicated with the cab air supply unit 1 in a limited space, and the effects of light weight and space saving are achieved while the function is ensured. The passenger compartment ducts 4 are L-shaped on both sides of the end of the passenger compartment, with one end arranged along both sides of the passenger compartment and the other end arranged transversely along the end and merging in the middle of the passenger compartment. The middle part of the air duct end plate of the passenger room at the junction is provided with a passenger room air supply outlet, the air duct end plate of the passenger room is at a distance from the partition wall of the driver cab, the transition air duct 3 enters the upper part of the passenger room from the upper part of the partition wall 10 of the driver cab and is connected with the air duct of the passenger room to supply air to the driver cab, and the top of the junction is sealed with the roof of the vehicle body through a sealing strip 8.
Referring to fig. 4, the transition duct 3 includes a soft duct 301, a square duct 302 fixed at both ends of the soft duct, and a mounting plate 303 welded at an end thereof, and sealing cotton is disposed at an outer side of the mounting plate. One end of the air duct joint is connected with a passenger room air supply outlet in an integrated sealing riveting mode, and the other end of the air duct joint is connected with a cab air supply unit through a bolt.
Referring to fig. 6, the cab air duct 2 is Y-shaped, one end of the duct is connected with the cab air supply unit 1 by bolts, the other end of the duct is divided into two branches, the two branches extend to the area above the main driver seat 9 and the auxiliary driver seat 9 respectively, and a plurality of adjustable air ports 5, generally 3 air ports, can be added according to needs, and can be adjusted by 360 degrees according to needs. Cab wind channel 2 is connecting 1 end of cab air supply unit and is expanding gradually towards locomotive direction inner chamber, both sides are the two branch road outsides of sealing connection respectively, two branch road inboard sealing connection, cab wind channel middle part forms a big buffer interval like this, wind that comes from cab air supply unit 1 is not directly blowing to adjustable wind gap 5 positions, but blow to in the buffer interval, it enlarges at this regional wind channel diameter, the wind speed reduces, through two branch roads of the steady flow direction of buffering back wind speed, the air current is more steady, air supply stability is better. The cab air duct 2 is manufactured in a pasting mode, an end mounting plate of the cab air duct is pasted with the air duct, and nuts are embedded in the end mounting plate and used for bolt connection.
When the cab air supply structure is assembled, due to manufacturing and assembling errors, the positions of the cab air supply unit 1 and the passenger room air supply outlet are possibly deviated from the design positions, the assembling interfaces between the cab air supply unit 1 and the passenger room air supply outlet cannot completely correspond, a transition air duct is connected between the cab air supply unit 1 and the passenger room air supply outlet, due to the fact that the transition air duct is a soft air duct, the cab air duct air supply structure can be well compatible in assembling errors and more flexible to assemble, meanwhile, the design accuracy requirement of the cab air duct is lowered, and more choices can be provided.
