Abstract
This application discloses a kind of C-shaped steel-aluminium composite conducting rail, awards fluid layer, aluminium and aluminium alloy conducting base including at least steel, conducting base is the C-shaped aluminium alloy extrusions that lumen width is more than channel opening width；Steel is awarded fluid layer and is fitting to connection with conducting base at least through a dovetail groove；Steel awards fluid layer width and is more than or equal to 90mm.The C-shaped steel-aluminium composite conducting rail that the application proposes is fitting to connection by dovetail groove, has compact compound interface；It is higher that conductor rail awards stream interface width autgmentability, can exceed 90mm；Its structure facilitates in-site installation and maintenance to change, particularly suitable for sidepiece by stream mounting means.Radiation tooth can be set on the aluminium alloy extrusions of the conductor rail, conductor rail level of heat generation is reduced in conductor rail current-carrying.
Description
Technical field
It the utility model is related to a kind of C-shaped steel-aluminium composite conducting rail.
Background technology
As the current-carrying main body of conductor rail electric power system, urban track traffic requires that conductor rail possesses preferable rigidity and strong
Degree, conductive current-carrying capacity, award stream interface anti-wear performance, decay resistance.Existing conductor rail such as Chinese patent CN100546845C institutes
Disclosed scheme, the main body of its conductor rail include base part, vertical column segment and head.Head side surface has groove.Face
Cover is fixed on head, and the sidepiece lower end of mask is terminated near groove outer end.The mask also includes the lower end for being welded in sidepiece
Continuous plate, the continuous plate extended into groove so that mask to be fixed on to the main body of conductor rail.Pair of this conductor rail
The convergent force that metal composite face only relies on after welding is adjacent to each other, therefore gap easily occurs in composite surface, causes pollutant to enter, and adds
The corrosion of fast conductor rail, and transition resistance is larger between causing steel aluminium；Such conductor rail also is difficult to raising and awards stream interface simultaneously
Width.
The content of the invention
The application purpose is to provide a kind of C-shaped steel-aluminium composite conducting rail have compact bimetallic compound interface,
Be advantageous to improve conductor rail decay resistance；There is wider stream interface of awarding simultaneously, reduce current density, extend the boots rail life-span.
To achieve the above object, the technical solution of the utility model is a kind of C-shaped steel-aluminium composite conducting rail, including at least steel
Fluid layer, aluminium and aluminium alloy conducting base are awarded, conducting base is the C-shaped aluminium alloy extrusions that lumen width is more than channel opening width；Steel
Fluid layer is awarded to be fitting to connection at least through a dovetail groove with conducting base；Steel awards fluid layer width and is more than or equal to 90mm.
Preferentially, it is provided with radiation tooth on the C-shaped conducting base of conducting base.
The beneficial effects of the utility model are：
1st, conductor rail is fitting to connection by dovetail groove in the application, has compact compound interface；
2nd, to award stream interface width autgmentability higher for conductor rail in the application, can exceed 90mm；
3rd, the matrix of conductor rail is more than the C-shaped aluminium alloy extrusions of channel opening width, this knot for lumen width in the application
Structure facilitates in-site installation and maintenance to change, particularly suitable for sidepiece by stream mounting means.
4th, the aluminium alloy extrusions of conductor rail is provided with radiation tooth in the application, and conductor rail hair can be reduced in conductor rail current-carrying
Heat level.
Brief description of the drawings
Accompanying drawing describes the utility model in detail, wherein：
Fig. 1 shows the cross-sectional view of the application steel-aluminium composite conducting rail；
Fig. 2 shows the cross-sectional view of the application another kind embodiment.
