Description
Technical field
The utility model relates to the city traffic field, specifically is a kind of base of the 3rd rail insulating support of underground railway track.
Background technology
At present, city underground adopts the third-rail current collection mode more, promptly outside two rails I-beam section of parallel laid as the 3rd rail (contact rail), the subway electric car by current-collecting device from third-rail current collection.
The unsettled setting of the 3rd rail, on the 3rd rail at a certain distance (as 4.5 meters) can be provided with one and be used to suspend in midair the 3rd rail insulating support of fixing the 3rd rail.Described the 3rd rail insulating support comprises base, insulator support and insulation fastener, described base is fixed on the track foundation, described insulator support is fixed on the madial wall of base, described insulation fastener and insulator support is fixed and form the chamber on ccontaining the 3rd rail top between the two.
As Fig. 1, the 3rd rail insulating support base of prior art shown in Figure 2, it comprises bottom of fixing with track foundation 101 and the sidepiece of fixing with insulator support 102, described bottom 101 and sidepiece 102 are one, straight plate 103 before described sidepiece 102 comprises, curved slab 107 and four parallel reinforced ribs, the top of straight plate 103 both sides and two interior reinforced ribs 104 is fixed before described, article two, outer reinforced rib 105 is fixed with the straight plate 106 of U type between two interior reinforced rib 104 both sides and their top, be equipped with a ramp plate 109 between described every outer reinforced rib 105 tops and every interior reinforced rib 105 tops, the lower end of described two blocks of ramp plates 109 is connected with the top of the straight plate 106 of U type respectively, between the lower part of described curved slab 107 reinforced rib 105 outside two, the lower part of described two interior reinforced ribs 104 all extends to curved slab 107 places, is provided with the declivity panel 108 that is used to connect preceding straight plate 103 and the straight plate 106 of U type between described two interior reinforced ribs 104.
There is following defective in the 3rd rail insulating support base of above prior art: the single submount material amount of expending is bigger, needs a large amount of bases and lay whole piece the 3rd rail, and the amount of expending of the base of one article of the 3rd rail stacks up, and quantity is very big, and the cost cost is very high.
The utility model content
The technical problems to be solved in the utility model is that the 3rd rail insulating support base of a kind of energy saving in material, reduction cost is provided.
Technical solution of the present utility model is, a kind of the 3rd rail insulating support base with following structure is provided, it comprises bottom and sidepiece, described bottom and sidepiece are one, described sidepiece comprises straight plate, curved slab is parallel to each other with three and the reinforced rib vertical with straight plate, described straight plate is whole plate, the top of described straight plate both sides and two outer reinforced ribs is fixed, the lower part of described two outer reinforced ribs and curved slab both sides are fixed, the top of the width centreline place of the outside face of described straight plate and a middle reinforced rib is fixed, and the lower part of described middle reinforced rib extends to the inboard middle and lower part of curved slab.
After adopting above structure, the utility model the 3rd rail insulating support base compared with prior art has the following advantages:
Can obviously find out under the prerequisite that intensity still adheres to specification at single base, single base has omitted a reinforced rib, and its material amount of expending obviously reduces, and the quantity of material that the base of whole piece the 3rd rail is saved stacks up, enormous amount has reduced the cost cost of the 3rd rail significantly.
