Description
Technical field
The invention belongs to technical field of rail traffic, specifically propose a kind of rail fastener system.
Background technique
Floating rail fastener is a kind of novel damping noise reduction rail fastener system, which supports by using elastic wedge
Rail head of rail lower jaw is carried, so that rail rail bottom is made to leave support rail seat, and the caoutchouc elasticity block as elastic bearing is then by being fixed on
The side panel of sub-rail foundation supports positioning.Each fastener node of floating rail fastener system is by a cast iron base, two cast iron sides
It is supported safely under panel bracket, two cast iron wedge block fixing pieces, two caoutchouc elasticity block elastic wedge rail braces, a rails
Rubber pad and two spring clip compositions.Under normal circumstances, safety bearing rubber pad is not contacted with rail, can effectively be limited in this way
Excessive deformation caused by load processed.Floating rail fastener structures are simple, are easily installed, and maintenance is convenient, and safety and stability is reliable, dedicated for
The location more demanding to vibration and noise reducing, such as the railroad bridge route of subway, urban district.Floating rail fastener system can be used to
Tiny fragments of stone, coal, etc. track, it can also be used to which non-fragment orbit, railroad track is widely used in countries in the world.
CN201621088118.5 discloses a kind of floating rail fastener, including for connecting sub-rail foundation substrate, be set to base
The bracket of rail is used to support above plate, the cavity between the bottom end and substrate of the rail is padded equipped with rail bottom；The rail bottom
The lower surface of liner is connect with substrate, and the upper surface of the rail bottom liner includes and discontiguous first resilient support in rail bottom end
Unit is symmetrically set in the second elastic support unit contacted on the outside of the first elastic support unit and with rail bottom end；The application relates to
And but be not limited to rail clip technical field, defect existing in the prior art, Neng Goubao can be effectively overcome using the application
Rail torsion stiffness with higher and higher vertical elasticity are demonstrate,proved, the ride comfort of rail can be made and comfort level is protected by bus
Card, while the generation of rail undulatory wear phenomenon is substantially reduced, the frequency of steel rail grinding is reduced to a certain extent.In the application
Positioning voussoir and supporting block are respectively provided with the groove being mutually twisted；It is tightly attached to supporting block in the side that positioning voussoir is equipped with groove
On, positioning voussoir is tightly attached in support plate far from the side of groove.
CN201120439915.4 proposes a kind of suspended steel rail vibration reduction fastener of chute-type installation, on fastener bottom plate with it is lateral
The position that bracket combines has the structure limited to lateral bracket, and position limiting structure should be at least with one to limit lateral
The confined planes I that bracket is moved along the laying direction of rail, and at least there is a limit to the vertical movement of limit lateral bracket
Plane II；Constituting between confined planes I, confined planes II makes lateral bracket make the space moved horizontally perpendicular to steel rail laying direction.
Lateral bracket moving in above-below direction and on steel rail laying direction can be effectively controlled in the utility model, and side also can be effectively controlled
The torsion generated to bracket by Rail torsion, and then effectively enhance the stability of lateral supporting structure, it is ensured that vehicle safety
Property.The roll adjustment block side abuts lateral bracket, and the other side corresponding with the side of lateral bracket roll adjustment block is abutted is tight
Has reeded side wall surface by fastener bottom plate；The roll adjustment block matches oblique each other with the contact surface of lateral bracket
Face, and combined between the inclined-plane to match for convex-concave fastening or plane；The roll adjustment block and the had groove of fastener bottom plate
Wall surface side be inclined-plane cooperation；The contact surface of another side wall surface of groove possessed by the roll adjustment block and fastener bottom plate
Matches mutually is faced directly, and match face directly between for convex-concave fasten or plane combine.
Though above now have laciniation or convex-concave fastening to carry out certain limitation, railway to voussoir position in the art
Operating conditions it is complicated, above zigzag fixed structure or convex-concave fastening are insufficiently resistant to caused vibration when vehicle passes through,
To guarantee the stability of fastener.
In During Process of Long-term Operation, two spring clips act on cast iron wedge block without vertical direction, and the impact of train is made
It will appear at cast iron wedge block and slowly float upwards；In addition because of reasons such as the deformation of rubber voussoir, casting accuracy and fit tolerances
Cast iron wedge block is caused to will appear the phenomenon that slowly floating upwards.It is insufficient to the deformation of rubber voussoir occur, rail is mentioned
The clamping force of confession reduces, to generate vicious circle, line status is caused gradually to deteriorate, and gauge, rail are not normal to changing, to make
Acutely shaking occurs in train, and severely impacts the ride comfort of people, endangers occupant's health, runs and cause for a long time to train
Greatly threaten.
In view of this, proposing the present invention.
