Abstract
A kind of heavy haul railway sleeper compound backing plate, effectively to limit the displacement of railway rail pad, reduces the rubbing action between rail support groove and backing plate, extends sleeper application life.Comprise resilient sleeper-bearing, be arranged with substrate at this resilient sleeper-bearing, the upper surface of this substrate has the positive stop lug boss raised up of longitudinal separation setting, and resilient sleeper-bearing then has the spacing hole corresponding with positive stop lug boss.Described substrate has the position limiting structure suitable with sleeper bolster groove.
Description
Technical field
The utility model relates to railway rail system, particularly a kind of heavy haul railway sleeper compound backing plate.
Background technology
Heavy haul railway has the remarkable advantages such as axle is great, freight volume large, good economy performance, environmental protection, and be widely applied in states such as the U.S., Australia, South Africa, China's expanding on Dalian-Qinhuangdao Railway is heavy haul railway, and annual traffic has reached 400,000,000 tons.The fatigue effect that heavy haul railway train axle is great, dynamic action between wheel and rail is strong, track structure bears is given prominence to, with conventional railway comparatively speaking, the Service Environment of heavy haul railway track structure is more severe.
At present, the rubber mat plate that heavy haul railway line uses wears to prevent moving groove, this groove connects with sleeper, and rubber cushion can only be prevented along the movement in rail direction, and rubber cushion can not be prevented along the movement in sleeper direction, in use often go here and there out, if string output is excessive, rubber mat plate by conquassation, inefficacy, can not have due effect, not only waste a large amount of maintenance labours and material, be also unfavorable for the kilter keeping circuit simultaneously.In addition, owing to can not limit the lateral displacement of backing plate, once there be soil to enter below rubber mat plate, will strengthen the rubbing action between rail support groove and rubber cushion, after long duration of action, peeling off appears in sleeper support rail surface concrete.Sleeper support rail surface concrete cannot be supplied to the load-carrying surface that fastener base plate provides smooth after peeling off, the disease such as easily cause fastener base plate conquassation, fastening elastic rod lax.After there is above-mentioned disease, sleeper must be changed.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of heavy haul railway sleeper compound backing plate, effectively to limit the displacement of railway rail pad, reduces the rubbing action between rail support groove and backing plate, extends sleeper application life.
It is as follows that the utility model solves the technical scheme that its technical problem adopts:
A kind of heavy haul railway sleeper compound backing plate of the present utility model, comprise resilient sleeper-bearing, it is characterized in that: resilient sleeper-bearing is arranged with substrate, the upper surface of this substrate has the positive stop lug boss raised up of longitudinal separation setting, and resilient sleeper-bearing then has the spacing hole corresponding with positive stop lug boss; Described substrate has the position limiting structure suitable with sleeper bolster groove.
The beneficial effects of the utility model are, by arranging the substrate of band positive stop lug boss below rubber mat plate, can effectively limit resilient sleeper-bearing displacement, resilient sleeper-bearing displacement can be prevented along the movement in rail direction, can limit again the transverse shifting of resilient sleeper-bearing; Substrate has the position limiting structure suitable with sleeper bolster groove, can reduce the interaction between rail support groove and substrate, effectively can solve sleeper support rail surface concrete and peel off problem, avoids peeling off because of track concrete changing sleeper, extends sleeper application life.
Accompanying drawing explanation
This manual comprises following six width accompanying drawings:
Fig. 1 is the cross-section structure of a kind of heavy haul railway sleeper of the utility model compound backing plate;
Fig. 2 is the top view of substrate component in a kind of heavy haul railway sleeper of the utility model compound backing plate;
Fig. 3 is the lateral view of Fig. 2;
Fig. 4 is the front view of substrate component in a kind of heavy haul railway sleeper of the utility model compound backing plate;
Fig. 5 is the top view of a kind of heavy haul railway sleeper of the utility model compound backing plate Elastic pad member;
Fig. 6 is the profile of a kind of heavy haul railway sleeper of the utility model compound backing plate Elastic pad member;
Component name shown in figure and corresponding mark: resilient sleeper-bearing 10, spacing hole 11, substrate 20, positive stop lug boss 21, defining flange 22.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
With reference to Fig. 1, a kind of heavy haul railway sleeper compound backing plate of the present utility model, comprise resilient sleeper-bearing 10, resilient sleeper-bearing 10 is arranged with substrate 20.With reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the upper surface of this substrate 20 has the positive stop lug boss 21 raised up of longitudinal separation setting.With reference to Fig. 5 and Fig. 6, resilient sleeper-bearing then has the spacing hole 11 corresponding with positive stop lug boss 21.Positive stop lug boss 21 matches with spacing hole 11 effectively can prevent resilient sleeper-bearing 10 displacement, resilient sleeper-bearing 10 displacement can be prevented along the movement in rail direction, can limit again the transverse shifting of resilient sleeper-bearing 10.With reference to Fig. 1, described substrate 20 has the position limiting structure suitable with sleeper bolster groove, can reduce the interaction between rail support groove and substrate 20, effectively can solve sleeper support rail surface concrete and peel off problem, avoid peeling off because of track concrete changing sleeper, extend sleeper application life.
Fig. 1 and Fig. 4 shows the adoptable form of structure of one of described position limiting structure, and namely position limiting structure is by the defining flange 22 of substrate 20 transverse ends soffit to lower convexity.
Some principles of the above a kind of heavy haul railway sleeper of the utility model compound backing plate that just explains through diagrams, be not the utility model to be confined to shown in and in described concrete structure and the scope of application, therefore every corresponding modify of being likely utilized and equivalent, all belong to the scope of the claims that the utility model is applied for.
