Rail is pressed on railway rail pad by track gauge block side and boss against, opposite side, and spring is placed on the boss of substrate and bullet
Bar one end is overlapped on track gauge block, railway spike from top to bottom pass through spring, road nail after stretch into the pre- sleeve pipe being embedded in sleeper and with
Casing threads connection locking is so that rail be positioned.But in actual use because the train carried on rail is long-term not
Repeated stock, spring, even track gauge block, substrate sheet after vibratory impulse repeatedly disconnectedly are carried out to rail and rail fastening device
Body is all likely to occur loosening and is subjected to displacement, and is that the traffic safety of train brings hidden danger；In addition, carrying out rail fastening device dimension
Be frequently necessary to when repairing maintenance dismantle railway spike, but dismantle railway spike during often occur the pre-buried sleeve pipe in sleeper with
Situation about being rotated with screw spike, not only influences the dismounting of railway spike but also can cause damage of the sleeve pipe in sleeper, afterwards
Increase system maintenance maintenance difficulty, improve maintenance cost.
The content of the invention
In view of the above-mentioned problems, the invention provides rail fastening device, it can solve the system that existing fastener device is present
The problem of security is low, the big cost of system maintenance difficulty is high.
Its technical scheme is, rail fastening device, and it includes substrate, railway rail pad and fastening component, and substrate is located at rail
On pillow and substrate is respectively arranged on the left side and the right side symmetrical boss, boss is provided with the road nail of the whole substrate of insertion, rail
Bottom is placed in by the railway rail pad on the substrate and between two boss, rail both sides are respectively by described in one group
Fastening component is fastened on the substrate, and the fastening component includes track gauge block, spring, railway spike and sleeve pipe, and described sleeve pipe is pre-buried
In in sleeper, the track gauge block includes holding out against portion and pressing plate portion, the pressing plate portion be arranged at described in hold out against portion towards rail side
Top, the track gauge block hold out against portion's both ends of the surface respectively with the boss, rail against and track gauge block pressing plate portion by steel
Rail pressure on railway rail pad, the railway spike pass through from top to bottom stretched into after the spring, road nail it is pre- be embedded in sleeper it is described
Sleeve pipe is simultaneously threadedly coupled locking with described sleeve pipe, it is characterised in that：The spring is to be set on W shape springs, the boss of the substrate
There is deep-slotted chip breaker, the deep-slotted chip breaker matches with the W shapes spring afterbody cambered surface.
It is further characterized by：The lateral surface of left and right two of the substrate is provided with vertical rib；The four of the base plate bottom
Individual angle end is equipped with circular arc protuberance；The bottom surface of the substrate offers the hole slot of some fovea superiors.
It is further characterized by：The one side of the track gauge block towards the substrate boss is provided with neck, the substrate
A side of boss towards the track gauge block be embedded in the neck.
Its further feature is more：The left and right sides end of the railway rail pad has symmetrical groove, the rail
The portion that holds out against away from plate is embedded in the groove towards the side of rail one.
It is further further characterized in that：Described sleeve pipe periphery top is smooth outer peripheral face, bottom provided with helicla flute, the set
The top peripheral of pipe is laid with vertically extending rib；The rib is provided with four；Described sleeve pipe periphery is also set with spiral
Muscle, the bottom of the spiral bar is embedded in corresponding helicla flute.
The beneficial effects of the present invention are：
（1）It on the boss of substrate by setting the deep-slotted chip breaker matched with W shape spring afterbodys, it is ensured that W shape spring afterbodys
Being brought into close contact between substrate boss, head and middle part and track gauge block, so that effectively control rail square block is by Long-term Vibration
It will not be subjected to displacement after impact, it is ensured that the security and stability of rail；
（2）It in substrate left and right sides by setting vertical rib, four angles of base plate bottom end to set circular arc to protrude respectively
The hole slot for some fovea superiors that portion and substrate bottom surface are opened up, can greatly reinforce the contact area between substrate and sleeper and friction
Adhesion, so as to ensure the stability of substrate and the rail being fastened on substrate；
（3）Boss one end of substrate is fitted together in the neck into track gauge block and a side end of track gauge block towards rail is simultaneously embedding
Be incorporated into the groove of railway rail pad, thus formed between substrate and track gauge block, the mutual constraint between track gauge block and railway rail pad,
Further it is prevented effectively from the mutual displacement between each part, it is ensured that the security and stability of rail；
（4）By be uniformly arranged in cannula tip periphery rib and sleeve pipe periphery be set with spiral bar come effectively improve sleeve pipe with
The adhesion of sleeper, so as to improve the withdrawal resistance of sleeve pipe, it is to avoid during railway spike is dismantled sleeve pipe rotate with railway spike and
Influence dismounting and the damage of sleeve pipe, therefore system maintenance difficulty, reduction maintenance cost can be reduced.
