Abstract
The invention relates to a mounting method for an air duct external flange of a rail vehicle. The air duct external flange comprises an external flange cylinder and an external flange edge, wherein the external flange cylinder is formed by arranging four wing plates in a surrounding manner; the bottom ends of the left and right wing plates of the external flange cylinder are flush with that of the external flange edge. The mounting method comprises the following steps: putting the pre-welded air duct external flange on the vehicle; moving the air duct external flange to an appointed position to ensure that the left and right wing plates of the external flange cylinder together with the external flange edge fall on a flat top plate of the vehicle while the four wing plates of the external flange cylinder are propped against a middle end top plate of the vehicle; welding the bottom ends of the left and right wing plates of the external flange cylinder and the bottom end of the external flange edge with the flat top plate of the vehicle through spot welding, and welding the four wing plates of the external flange cylinder with the middle end top plate of the vehicle through spot welding, so as to fix the air duct external flange; welding the four wing plates of the external flange cylinder with the middle end top plate of the vehicle through full welding. The air duct external flange mounted according to the mounting method has the advantages that the mounting requirement of an air conditioner external air duct and the sealing requirement of a steel structure of a vehicle body can be met simultaneously; the structure is simple; the technology is easy to realize.
Description
Technical field
The present invention relates to air ducts of railway vehicle outward flange installation method, belong to track vehicle body structure design field.
Background technology
Flat-top 7 in trolley coach steel structure of car roof is mainly used for the unit 4 that installs an air-conditioner, the air channel connecting air conditioner is divided into two by middle ends top 1, outside middle ends top 1 is outer air duct 5, within middle ends top 1 is interior air channel 6, both are connected by outward flange 3,2 in steel structure air channel, as shown in Figure 1.
In air channel outward flange middle ends top place connect, in order to ensure connect after sealing property, air channel outward flange need with border, middle ends top full weld (Fig. 1 arrow place), but the prerequisite realizing full weld is air channel, and outward flange end opening has enough operational spaces to flat-top.
Track traffic career development is maked rapid progress, the kind of guideway vehicle is also more and more, the roof height of each guideway vehicle project, the flat-top height installed an air-conditioner also are different, encounter the situation that outward flange border, multiple air channel full weld cannot realize in recent years.In order to ensure the sealing property of car body, the interface on air channel outward flange end opening and middle ends top takes the mode of playing glue, but sealing situation is unsatisfactory, a kind of middle ends road outward flange structure against the wind must be innovated, the sealing property of the installation requirement that simultaneously can meet outer air duct in air-conditioning and steel structure of car body herein.
Summary of the invention
Technical matters to be solved by this invention is, overcomes the above-mentioned shortcoming of prior art, provides a kind of air ducts of railway vehicle outward flange installation method.
In order to solve above technical matters, air ducts of railway vehicle outward flange installation method provided by the invention, described air channel outward flange comprises outward flange cylinder and outward flange limit, it is characterized in that: described outward flange cylinder is surrounded by four blocks of wing plates, the bottom of outward flange cylinder left and right sides wing plate flushes with the bottom on outward flange limit; Installation steps are as follows:
The first step, the air channel outward flange welded in advance to be got on the bus;
Second step, air channel outward flange move to assigned address, make outward flange cylinder left and right sides wing plate and outward flange limit together drop on vehicle ceiling, and four wing plates of outward flange cylinder are close to vehicle middle ends top board;
3rd step, wing plate bottom, the outward flange cylinder left and right sides and bottom, outward flange limit and the spot welding of vehicle ceiling, four wing plates of outward flange cylinder and the spot welding of vehicle middle ends top board, make air channel outward flange fix;
Four wing plates of the 4th step, outward flange cylinder with carry out full weld between vehicle middle ends top board and weld.
The present invention also has following improvement:
1, the wing plate of the described outward flange cylinder left and right sides is parallel to each other.
Air ducts of railway vehicle outward flange structure of the present invention, conventional structure basis is innovated, have employed brand-new project organization and welding process, and expanded in outward flange nozzle footpath, air channel, wing plates on two sides and flange extend to ceiling bottom.When roof formal dress, air channel outward flange is directly fallen on flat-top, air channel outward flange cylinder wing plate directly welds with ceiling bottom with flange, the side of air channel outward flange wing plate is welded with middle ends top board, such air channel outward flange structure can meet the installation requirement of air-conditioning outer air duct and the requirement of steel structure of car body sealing property simultaneously, and structure is simple, technique realizes easily.The present invention program can not realize there is good value of service in the vehicle of full weld at traditional air chute outward flange and middle ends top.

Detailed description of the invention
As shown in Figures 1 to 4, the air ducts of railway vehicle outward flange that the present embodiment will be installed, comprises outward flange cylinder 8 and outward flange limit 9, and outward flange cylinder 9 is surrounded by four blocks of wing plates, outward flange cylinder 9 left and right sides wing plate is parallel to each other, and its bottom flushes with the bottom on outward flange limit 8.
Installation steps are as follows:
The first step, the air channel outward flange welded in advance to be got on the bus;
Second step, air channel outward flange move to assigned address, make outward flange cylinder 9 left and right sides wing plate and outward flange limit 8 together drop on vehicle ceiling 7, and four wing plates of outward flange cylinder 9 are close to vehicle middle ends top board 1;
3rd step, wing plate bottom, outward flange cylinder 9 left and right sides and bottom, outward flange limit 8 and vehicle ceiling 7 spot welding, four wing plates of outward flange cylinder 9 and the spot welding of vehicle middle ends top board 1, make air channel outward flange fix;
Four wing plates of the 4th step, outward flange cylinder 9 with carry out full weld between vehicle middle ends top board 1 and weld, realize sealing at this place.
