Description
Technical field
The utility model relates to rail elastic bar fastener systems, more particularly to a kind of axis that is suitable for weigh 35~40 tons of heavily loaded iron
The non-bolt fastener assemblies on road.
Background technique
Heavy haul railway transports extensive attention due to its capacity is big, high-efficient, transportation cost is low by countries in the world railway,
Such as U.S., Brazil, Australia, largely starts heavy haul train on the heavy haul railway of South Africa at Canada, in Europe based on passenger traffic
Passenger-cargo mixed fortune main line on also start to start heavy haul train.Important component one of of the fastener as track structure, to holding
Gauge, enhancing track structure stability play a significant role.
Non-bolt fastener is turned into because its structure simply avoids bolt oiling and nut terminal operation simultaneously convenient for machinery
Industry, and installation maintenance workload is greatly reduced, it will be widely welcomed, especially the higher developed country of cost of human resources.
The non-bolt fastener structures pattern that heavy haul railway, general fast railway and high-speed railway use both at home and abroad at present have the advantages that it is above
Also have itself clearly disadvantageous simultaneously, when being mainly shown as that rail bears the relatively larger transverse significant torsional deflection of load generation, by
In this kind of e shape spring without the secondary limiting device withheld rigidity or prevent excessive deformation, it is excessive to easily cause spring residual deformation
And lose buckle press, such as by AREMA standard carry out big lateral load drag test when, spring easily fails.
Utility model content
The technical issues of the utility model is solved is to provide a kind of nothing for weighing 35~40 tons of heavy haul railways suitable for axis
Bolt fastening component.To solve the disadvantage in above-mentioned background technique.
The technical problem solved by the utility model is implemented by the following technical solutions:
A kind of non-bolt fastener assemblies weighing 35~40 tons of heavy haul railways suitable for axis, including preburied iron base, e shape spring,
Insulation rail distance keeper, rubber mat plate, the pre-plugged preburied iron base when making concrete sleeper, e shape spring are inserted by the second heel end
Enter preburied iron base and withhold rail, Insulation rail distance keeper, rail and concrete sleeper support rail face are set between preburied iron base shoulder block and rail
Between set rubber mat plate, by e shape spring withhold limb heel end setting L shape keep off end, withhold limb close to e shape spring in the preburied iron base
The aperture of heel end position, L shape gear end are protruded into the aperture.
Further, L-type shelves end end is provided with contact tooth socket.
Further, the second heel end is provided with groove compatible with L-type shelves end.
Further, the tooth socket of L-type shelves end end and the groove of the second heel end contact engaging in the preburied iron base
Together.
Further, it is suitable for axis and weighs 35~40 tons of heavy haul railways.
Further, when normal mounting, described e shape spring L shape gear end is not contacted with preburied iron base, do not influence described in
The normal mounting and stress of e shape spring；When larger torsional deflection occurs for rail, the described L shape gear end of rail side can on
It moves and along contacting, generates biggish drag prevention Rail torsion deformation in the preburied iron base aperture, thus prevent described
E shape spring because deform it is excessive due to fail.
Further, when larger torsional deflection occurs for rail, the L shape gear end of rail side and the second heel end are fastened on one
It rises, generates biggish drag and Rail torsion is prevented to deform, thus prevent e shape spring excessive because deforming due to fail.
Occur significantly the utility model has the beneficial effects that: existing non-bolt fastener bears relatively larger transverse load in rail
When torsional deflection, since e shape spring is without the secondary limiting device withheld rigidity or prevent excessive deformation, spring remnants are easily caused
When deforming excessive and lose buckle press, for example carrying out the test of big lateral load drag by AREMA standard, spring easily fails.
The utility model is the Curve guide impeller for passing through spring and preburied iron base on the basis of existing technology, and fastener is enable to resist rail
Excessive torsional deflection.When fastener normal mounting, L shape gear end is not contacted with preburied iron base, do not influence the normal mounting of spring with
Stress；When larger torsional deflection occurs for rail, the L shape gear end of rail side will be shifted up in preburied iron base aperture along contacting or
The L shape gear end of person's rail side and the second heel end are fastened togather, and generate biggish drag and Rail torsion is prevented to deform, so as to
It prevents from failing due to spring is excessive because deforming, the utility model is particularly suitable for axis and weighs 35~40 tons of heavy haul railways.
