Abstract
本实用新型地铁车辆废排风机接口结构，采用整体冲压成型的侧顶板替代车顶波纹板，从而在整体冲压成型的排风口处安装法兰接口部件。以整体冲压成型的侧顶板来准确地规范所形成排风口的规格尺寸，有效地降低法兰接口件与排风口之间形成的焊缝，避免了雨水聚集而导致的渗漏问题的发生。接口结构包括有沿车体纵向铺设的侧顶板，在侧顶板上设有排风口，在排风口上连接有法兰接口件，侧顶板的两侧与波纹顶板缝焊连接。作为专用部件的侧顶板既与波纹顶板共同覆盖车顶骨架，同时又承担支撑废排风机法兰接口件的承载平台。
The interface structure of the waste exhaust fan of the subway vehicle of the utility model adopts an integrally stamped and formed side roof plate to replace the roof corrugated plate, so that a flange interface component is installed at the integrally stamped and formed air exhaust port. The integrally stamped side top plate is used to accurately regulate the size of the formed air outlet, effectively reducing the weld between the flange interface and the air outlet, and avoiding the occurrence of leakage problems caused by rainwater accumulation . The interface structure includes a side roof laid longitudinally along the vehicle body, an air outlet is arranged on the side roof, and a flange interface piece is connected to the air outlet, and both sides of the side roof are seam-welded with the corrugated roof. The side top plate as a special component not only covers the roof frame together with the corrugated top plate, but also serves as a bearing platform for supporting the flange interface parts of the waste exhaust fan.
Description
Technical field
The utility model is the improvement design at the useless exhaust fan mounting structure at railcar roof position, and firm useless exhaust fan supporting construction is provided particularly, belongs to mechanical manufacturing field.
Background technology
The existing domestic urban track traffic instrument that generally uses, as subway, urban light rail etc., quality of air environment has designed air renewal, convection device in the car in order to improve, as useless exhaust fan is installed at large to discharge the waste gas in the car at the roof position.
Install when giving up exhaust fan at existing vehicle passenger cab top, and it supports mounting structure and normally carry out existing car perforate on the roof corrugated plating, inserts the blower fan mounting flange with this, subsequently with integrally welded structure between mounting flange and roof corrugated plating.
Because in the above-mentioned existing technology, perforate lacks the corresponding standard rule on the corrugated plating, causes the gap between mounting flange and the corrugated plating inhomogeneous, thereby when welding, be prone to the generation that bigger weld seam causes problems such as leaking.
The utility model content
The railcar described in the utility model exhaust fan interface structure that gives up is to solve the problem that above-mentioned prior art exists and adopts whole stamping forming side top board to substitute the roof corrugated plating, thereby at the stamping forming exhaust outlet of integral body place mounting flange interface unit.
Design goal is, comes the specification of exhaust outlet that standard is formed exactly with the stamping forming side top board of integral body, reduces the weld seam that forms between flange-interface spare and the exhaust outlet effectively, has avoided rain water-harvesting and the generation of the leakage problems that causes.
For realizing above-mentioned design goal, the useless exhaust fan interface structure of described railcar mainly includes:
Along the vertical side top board of laying of car body,
Be provided with exhaust outlet on the side top board, be connected with flange-interface spare on exhaust outlet, the both sides of side top board are connected with the weldering of ripple top board seam.
As above-mentioned basic scheme feature, both covered the roof skeleton jointly as the side top board of special-purpose member with the ripple top board, bear the carrying platform that supports useless exhaust fan flange-interface spare simultaneously again.
For specification, the control of standard exhaust outlet better and reduce weld seam, the innovative approach that can take is, exhaust outlet is to form integral structure by whole punch forming with the side top board, and exhaust outlet has the sidepiece turnup structure.
The side top board is provided with the exhaust outlet of band flange, can be on exhaust outlet direct mount flange-interface spare.
The sidepiece turnup structure that is flange-interface spare by exhaust outlet is connected in the side top board.
For improving effectively being connected and sealing property of side top board and ripple top board, side top board and ripple top board also can adopt seam welder skill.
Content to sum up, the useless exhaust fan interface structure of described railcar has the following advantages:
1, takes special-purpose side top board, substitute on the ripple top board, the begin to rehearse technology in air port of existing car, reached standard exhaust outlet size, simplified the purpose of production technology with the outlet structure of stamping forming band flange.
2, exhaust outlet has flange and adopts whole punch forming process manufacturing, has avoided the weld defect that welded structure may produce and the rainwater that causes oozed the dew problem.
3, adopt welding process between the flange-interface spare of useless exhaust fan and side top board exhaust outlet, seam is arranged on the exhaust outlet flange, has avoided the rain water-harvesting of commissure, has reduced the weld seam corrosion that produces because of rain water-harvesting or the risk of rain leakage.
4, adopt the seam weldering to be connected technology between side top board and both sides ripple top board, both improved Joint strenght, realized being tightly connected between side top board and ripple top board again.
Description of drawings
Now in conjunction with the following drawings the utility model is described further;
Fig. 1 is the scheme drawing of the useless exhaust fan interface structure of described railcar;
Fig. 2 is that A-A among Fig. 1 is to cut-away view;
Shown in above-mentioned accompanying drawing, side top board 1, flange-interface spare 2, ripple top board 3, exhaust outlet 4.
The specific embodiment
To shown in Figure 2, the useless exhaust fan interface structure of described railcar mainly includes as Fig. 1:
Be connected with flange-interface spare 2 on exhaust outlet 4, the both sides of side top board 1 are connected with the 3 seam welderings of ripple top board.
Described exhaust outlet 4 is to form integral structure by whole punch forming with side top board 1, and exhaust outlet 4 has the sidepiece turnup structure.
Flange-interface spare 2 is connected in side top board 1 by the sidepiece turnup structure of exhaust outlet 4.
