Description
Technical field
The present invention relates to the repair apparatus of railroad track, more particularly to a kind of track screw is screwed automatically and oiling is small
Car.
Background technology
In recent years, the trend of national passenger rail development is high speed, big density and heavy duty, track coupling component failure hair
Raw frequency more and more higher is, it is necessary to which the workload of maintenance is also increasing.It is mostly important one in track maintenance repair
Part, wherein frequency highest are the inspections of bolt and tightened.If bolt looseness problem can not be solved in time, it will right
The operation of vehicle causes safely high risks.Because oiling workload is big, oiling work and bolt fastening work are closely bound up, because
This, oiling work is also badly in need of automated machine to complete.Track coupling component failure refers mainly to fastener, and pine occurs in connecting bolt etc.
It is dynamic, crackle, corrosion, the defect such as fracture.The loosening of nut is wherein most frequently happens is that, nut loosening can cause rail position to be sent out
Changing, can greatly jeopardize traffic safety, through analysis, cause loosen the reason for mainly have it is following some：
(1) cartridge and bolster loose contact
It is plane contact between cartridge, backing plate, bolster, screw bolt used on bottom center plate pretightning force is not enough or cartridge is contacted not with bolster
Good, cartridge causes bolt looseness relative to bolster gliding dislocations.
(2) influence of material
The wood materials that cartridge backing plate is used, although its coefficient of friction is high compared with steel padding, but resisting due to wooden backing plate
Compressive Strength is not enough, is acted on by natural drying shrinkage and the quiet dynamic loading of car body, after a certain period of use time, it may occur that skew is damaged,
And the contracting of wooden backing plate becomes makes bolt without pretightning force again, so as to lose self-locking performance and loosen.
(3) influence of working environment
Bolt connection is detachable connection, what its self-lock ability was realized mainly by the frictional force in bolt pair.
This frictional resistance will not change under dead weight.And when being continually subjected to vibrate, impact, varying load effect when, spiral shell
Frictional resistance in bolt pair will reduce, or even momentary loss phenomenon occur.Train includes spring vibration damper in itself, and it runs
Stationarity is poor.When by rail gap joint, track switch, it vibrates, impulsive force is larger, and vibration frequency is higher, when nut is located for a long time
When under this environment, will occur loosening phenomenon, or even come off.
The content of the invention
