Description
Technical field
Track traffic is the utility model is related to, more particularly to a kind of suspension type sky rail rail structure out of shape.
Background technology
Suspension type sky rail track girder is the Thin Walled Steel Box Beam of lower opening, and train runs on track girder by way of suspension
Lower section, bogie is located at box house.Track girder provides load-bearing and guide effect for train, and is tractive power supply system
Carrier, it, which collects, various engineering and acts on one, therefore technically needs certain intensity, rigidity and stability.
Due to the particularity of carrier, the detailing requiments of track girder are complicated.First, its inner space clear span, clear height size
Structure limitation will meet track girder overall structure stability demand.Track girder side wall, running face, reinforcing plate are thin using steel
Wall, its thickness is all very small compared with its height and longitudinal span, is typical thin-wall construction.Track girder is bearing train traveling
While caused vertical load, larger lateral load and moment of torsion are also carried.Secondly, the bulk of track girder needs full
Sufficient vehicle and track clearance requirement.
The main body of existing track girder is welded by the left web of steel, right web, top plate, left-side bottom and right side bottom plate
Form, left web, right web lateral separation are erect and be welded in top board undersurface, left web, right web lower end difference
Left-side bottom, right side bottom plate are welded to connect, is formed below Thin Walled Steel Box Beam and opened between left-side bottom, the opposite end face of right side bottom plate
Mouthful.Left-side bottom, right side bottom plate require certain rigidity as rail, therefore generally in left-side bottom, right side bottom plate
Bottom surface on weld longitudinal stiffener.This track girder structural form can meet requirement substantially, but it has certain lack
Fall into, be mainly manifested in, left-side bottom is with left web, right side bottom plate and right web using bilateral angle welding, and it is only
Bevel carries out penetration weld near beam-ends so that the whole tired allowable stress of track girder here is smaller；Longitudinal stiffener
Left-side bottom, right side bottom plate is caused to have larger residual stress and strain after using penetration weld with left-side bottom, right side bottom plate, and
It is difficult to eliminate, and left-side bottom, right side bottom plate are the track for directly bearing wheel load, the size of its overstrain directly affects
Road-ability, the size of residual stress directly affect structure service life, meanwhile, one can also be increased by having more a weld seam herein
The fixed construction period.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of suspension type sky rail rail structure out of shape, to effectively improve
The anti-fatigue performance and ride comfort of road beam rail.
Technical scheme is as follows used by the utility model solves its technical problem：
Suspension type sky rail rail structure out of shape of the present utility model, including it is fixedly welded on abdomen on the left of suspension type sky rail track girder
Plate, the bottom plate of right web lower end, the laterally spaced abutting end of two pieces of bottom plates form the lower opening of suspension type sky rail track girder,
It is characterized in that：The bottom plate has longitudinal stiffener structure on the bottom surface of laterally inboard, on the top surface of lateral outer side
With longitudinal rib formations, longitudinal stiffener structure, longitudinal rib formations and bottom plate one roll forming；The top of the longitudinal rib formations
Penetration welding is docked with left web, right web lower end in end.
The beneficial effects of the utility model are that the both sides bottom plate as rail has longitudinal stiffener knot using bottom surface rolling
The deformed steel flats of structure, its bottom surface do not have solder joint, it is ensured that the ride comfort of track girder rail, and greatly improve rail out of shape
Anti-fatigue performance, and reduction weld seam can save certain duration；Bottom plate is empty by the longitudinal rib formations on top surface and suspension type
The left web of rail track girder, right web docking penetration welding so that the whole fatigue behaviour of track girder here has larger
Raising.
Brief description of the drawings
This specification includes following two width accompanying drawing：
Fig. 1 is the sectional drawing of the utility model suspension type sky rail rail structure out of shape；
Fig. 2 is the sectional drawing that the utility model suspension type sky rail rail structure out of shape is applied to suspension type sky rail track girder.
Component and corresponding mark are shown in figure：Left web N11, right web N12, top plate N2, bottom plate N3, longitudinal direction add
Strength rib structure N31, longitudinal rib formations 32, spacing steel plate N4, left side vertical plate N51, right side riser N52.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
Referring to Figures 1 and 2, suspension type sky rail rail structure out of shape of the present utility model, including it is fixedly welded on suspension type sky
Rail track girder left web N11, the bottom plate N3 of right web N12 lower ends, two pieces of laterally spaced abutting ends of bottom plate N3 form outstanding
The lower opening of hanging empty rail track girder.The bottom plate N3 has longitudinal stiffener structure N31 on the bottom surface of laterally inboard,
There is longitudinal rib formations 32, longitudinal stiffener structure N31, longitudinal rib formations 32 and bottom plate N3 mono- on the top surface of lateral outer side
Body roll forming.Bottom plate N3 bottom surfaces do not have solder joint, it is ensured that the ride comfort of track girder rail, and greatly improve rail out of shape
Anti-fatigue performance, and reduce weld seam can save certain duration.The top of the longitudinal rib formations 32 and left web
N11, right web N12 lower ends docking penetration welding so that the whole fatigue behaviour of track girder here is greatly improved, and
It is easy to improve welding job efficiency.
Reference picture 1, to make the both sides bottom plate N3 as rail that there is certain rigidity, the longitudinal stiffener structure
N31 is horizontally arranged at interval at least twice on bottom plate N3 bottom surface.
Reference picture 2, the interior welding in the middle part of top plate N2 bottom surfaces of Thin Walled Steel Box girder construction set position limiting structure in track girder.Rail
Position limiting structure is made up of spacing steel plate N4, left side vertical plate N51 and right side riser N52 in road beam, left side vertical plate N51, right side riser
N52 lateral separations are erect and are welded on top plate N2 bottom surfaces, and its lower end is welded to connect spacing steel plate N4.
Some principles of the utility model suspension type sky rail rail structure out of shape described above that simply explains through diagrams, it is not
The utility model is confined in shown and described concrete structure and the scope of application, therefore every phase for being possible to be utilized
It should change and equivalent, belong to the apllied the scope of the claims of the utility model.
