Brief description
Fig. 1 is straddle-seat type single traffic rail beam sectional view of the prior art；
Fig. 2 is the cross-sectional view with the track girder evacuating inspection platform according to one embodiment of this utility model；
Fig. 3 is the structural representation according to the evacuation inspection platform in the track girder of one embodiment of this utility model.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.It should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.Additionally, institute in each embodiment of this utility model disclosed below
As long as the technical characteristic being related to does not constitute conflict each other just can be mutually combined.
According to the straddle type monorail rail tracks with evacuation inspection platform of one embodiment of this utility model, as Fig. 2 institute
Show, including two spar-boxes 1, it is oppositely arranged, setting distance is wheel of vehicle width, two spar-boxes 1 as the web of track girder, with point
Not as the track of vehicle to run.
As shown in Figures 2 and 3, two spar-box 1 bottom is connected as a single entity by a base plate 2, and two spar-boxes 1 and this base plate 2 combine shape
Become u shape structure.
Base plate 2 is preferably integrally formed by cast it is also possible to separate moulding by casting with two spar-boxes 1.Base plate 2 is tied for casing
Structure, its inner hollow, base plate 2 in rail both sides side transversely is substantially flush with the outer surface of two spar-boxes 1 of respective side.
This structure arrangement makes that this two-wire track beam structure is compact, and the scale of construction is less, makes that its construction is simple simultaneously again, and structure is attractive in appearance.
In this programme, the track girder of u-shaped structure, the space that its u shape surrounds is very big, is provided with as safe escape passage
And/or the evacuation inspection platform 3 of maintenance access path.
