Description

Low-floor tramcar roof is connected mounting process with side wall
Technical field
The present invention relates to a kind of low-floor tramcar roof and side wall connecting structure mounting process, belong to vehicle body of railway vehicle design field.
Background technology
The equipment of low-floor tramcar is typically mounted on roof, owing to weight of equipment is bigger, need below roof panels to arrange that beam structure carries, and the junction of crossbeam and side wall needs to bear bigger power, common practice is to arrange an elongated channel-section steel in side wall and roof junction, and roof cross beam is plugged on channel-section steel intracavity.The program has the shortcomings such as cost is high, weight is big, technique grafting inconvenience.Therefore, work out a kind of novel lighter, cheap and convenient construction attachment structure and there is the most real engineering significance.
Summary of the invention
The technical problem to be solved is, overcomes the shortcomings such as the roof of slab and girder is high with the attachment structure cost of side wall, weight is big, technique is inconvenient in prior art middle orbit vehicle, it is provided that a kind of low-floor tramcar roof is connected mounting process with side wall.
In order to solve above technical problem, the low-floor tramcar roof that the present invention provides is connected mounting process with side wall, including sidewall section and top of car, sidewall section has column, window entablature, framed side wallboard, connection seat and connecting plate, top of car has roof panels and head piece, and mounting process comprises the following steps:
S1, column and window upper cross beam welding are fixed;
S2, framed side wallboard are weldingly fixed on column and the outside of window entablature;
S3, will connect seat lower end weld with column, connect seat outer end weld with framed side wallboard, framed side wallboard top bend and be connected seat upper end weld, connecting plate be welded on connection seat the inner, formation side wall module;
S4, roof panels is welded on the top of roof cross beam, forms roof module;
S5, being spliced with roof module by side wall module and be directed at, two ends and the connecting plate of roof cross beam are welded and fixed, and roof panels is welded with the bending upper surface of framed side wallboard.
Mounting process of the present invention is easy to the big modularized production of body construction, improves production efficiency.Crossbeam after installation can be good at meeting the requirement of roof carrying, but also can arrange different number of connection seat easily and flexibly according to the difference of the different region load capacity of roof, consequently facilitating the loss of weight of body construction.
Accompanying drawing explanation
The present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is low-floor tramcar roof and side wall connecting structure schematic diagram.
Fig. 2 is low-floor tramcar roof and side wall connecting structure side sectional view.
In figure, label is schematically as follows:
1-connects seat, 2-roof cross beam, 3-window entablature, 4-framed side wallboard, 5-roof panels, 6-connecting plate, 7-column.
Detailed description of the invention
As shown in Figure 1 and Figure 2, for the present embodiment low-floor to be mounted tramcar roof and side wall connecting structure, its composition includes: column 7, framed side wallboard 4, roof panels 5, roof cross beam 2, connection seat 1 and connecting plate 6, framed side wallboard 4 is welded and fixed with column 7, roof cross beam 2 is welded and fixed with roof panels 5, connect seat 1 with base be welded and fixed with column 7 upper end, the outer end and the upper end that connect seat 1 are welded and fixed with framed side wallboard 4, the inner connecting seat 1 is welded and fixed with connecting plate 6, and connecting plate 6 is welded and fixed with the end of roof cross beam 2.Connect seat 1, connecting plate 6, column 7, framed side wallboard 4 and weld formation side wall module in advance;Roof panels 5 welds formation roof module in advance with roof cross beam 2.As it is shown in figure 1, one piece of connecting plate 6 is fixed on two the inners connecting seat 1.Window entablature 3 is fixed with column 7 and framed side wallboard 4.As in figure 2 it is shown, fix with the welded top being connected seat 1 after the bending of framed side wallboard 4 upper end;Roof panels 5 is welded and fixed with the bending upper surface of framed side wallboard 4.
The present embodiment low-floor tramcar roof is as follows with the installation method of side wall connecting structure:
S1, column 7 and window entablature 3 are welded and fixed;
S2, framed side wallboard 4 are weldingly fixed on column 7 and the outside of window entablature 3;
S3, being welded with column 7 connection seat 1 lower end, connect seat 1 outer end and weld with framed side wallboard 4, the bending of framed side wallboard 4 top is welded with the upper end being connected seat 1, and connecting plate 6 is welded on the inner of connection seat 1, formation side wall module;
S4, roof panels 5 is welded on the top of roof cross beam 2, forms roof module;
S5, being spliced with roof module by side wall module and be directed at, two ends and the connecting plate 6 of roof cross beam 2 are welded and fixed, and roof panels 5 is welded with the bending upper surface of framed side wallboard 4.
In addition to the implementation, the present invention can also have other embodiments.The technical scheme that all employing equivalents or equivalent transformation are formed, all falls within the protection domain of application claims.
