Description
Technical field
The present invention relates to railway traffic equipment, especially a kind of reduction curve segment of railway from inclining wheel-rail wear device.
Background technique
With the continuous development of China's transportation business, safe rail transportation environments are constructed, are to push railway cause
The important foundation of development.Since railway comes out, Track irregularity is just always problem present on railway curve, especially
On the sharp radius curve of mountain area, side wear aggravation, internal rail is seriously crushed, and wheel rim of locomotive unilateral side eccentric wear considerably increases railway
Transportation cost, reduce the service life of rail track.Therefore, improve rolling stock curve negotiating condition, slow down its wheel track
Wear rate extends the service life of transporting equipment, and the railway transport economy benefit for promoting China is of great significance.
In order to improve train curve negotiating condition, slow down wheel-rail wear rate, the method that China is widely used at present is main
There are two types of.One is superelevation of outer rail methods, i.e., by the way that suitable track superelevation value is arranged in curve section foreign stock rail, balance train
By when generated centrifugal force, reduce the cross force between wheel track, to achieve the purpose that reduce wheel-rail wear indirectly, however,
It being found during actual operation, superelevation of outer rail method still comes with some shortcomings in terms of reducing wheel-rail wear, it is mainly shown as,
When train is when curve track is run at high speed, if actual elevation is insufficient, just can not centrifugal force caused by active balance train, with
It causes rolling stock to be pushed to foreign stock rail, increases the abrasion of foreign stock rail；If actual elevation is excessive, rolling stock again can be by it certainly
It weighs the influence of component and is biased to interior stock rail, cause interior stock rail conquassation disease, the serious service life for reducing rail track.Separately
A kind of method is the oiling of rail side, reduces the side frictional force between wheel track, thus achieve the purpose that reduce wheel-rail wear, but
The oiling of rail side needs to consume a large amount of manpower object there is also some potential problems, such as track residual greasy dirt cleaning difficulty
Power etc..
Summary of the invention
It is an object of the invention to provide one kind can effectively slow down wheel-rail wear rate, and extend transporting equipment uses week
Phase increases the overall stability of curve track, improves the reduction curve segment of railway from inclining wheel of train operation stationarity and degree of passenger comfort
Rail attrition apparatus.
A kind of reduction curve segment of railway from inclining wheel-rail wear device of the invention, including drop wheel-rail wear ontology, flexible bearing rod,
It is characterized in that, drop wheel-rail wear ontology is mounted on the two bursts of rail middle positions in left and right on sleeper, and fixed with anchor bolt,
It is provided with groove in the middle part of drop wheel-rail wear ontology direction along ng a path, is mounted on ontology on the drop wheel-rail wear ontology of groove two sides
Electromagnet, the circuit controling element of control ontology electromagnet are located in drop wheel-rail wear ontology；Flexible bearing rod is fixed on
In bogie, its underpart movable end is equipped with vehicle mounted electric magnet, and stretch load pole length retractable, and vehicle mounted electric magnet is with flexible
In groove when bearing rod stretches out in the middle part of insertion drop wheel-rail wear ontology, the both ends polarity and adjacent bodies electromagnetism of vehicle mounted electric magnet
The polarity of iron is identical.
A kind of reduction curve segment of railway from inclining wheel-rail wear device of the invention utilizes electromagnet homopolar-repulsion, heteropolar attracting
Principle, by the repulsive interaction between drop wheel-rail wear ontology and flexible bearing rod, is adjusted in real time by controlling the work of electromagnet
Position of the flexible bearing rod in drop wheel-rail wear body recess, is in it at groove center line always, meanwhile, stretch load
Bar also will drive bogie and wheel to synchronous cross movement is made, so that there is gap between certain trip between wheel track always, to drop
Impact and abrasion between low wheel track.The specific working principle is as follows is for it, train i.e. by arrival curve section when, signal system starts
The bearing rod that stretches inside control bogie extends automatically, and at the same time, ontology electromagnet and vehicle mounted electric magnet are started to work, wait arrange
Behind vehicle arrival curve section, the vehicle mounted electric magnet of flexible bearing rod lower end can be fully inserted into just to drop wheel-rail wear ontology
Among groove, at this point, the two poles of the earth of vehicle mounted electric magnet are opposite with the two poles of the earth of ontology electromagnet.When curve track owes superelevation, arranged
Vehicle centrifugal forces affect, bogie and wheel are traversing to outer rail generation to will drive flexible bearing rod, at the same time, one end ontology electromagnetism
Repulsive interaction increases severely between iron and vehicle mounted electric magnet, exactly prevents the trend that flexible bearing rod is traversing to outer rail, so also just prevents
Bogie and to take turns opposite outer rail traversing, eventually reduces wheel to the impact and abrasion outer rail；When curve track crosses superelevation
When, by train self weight component influences, bogie and wheel are traversing to internal rail generation to will drive flexible bearing rod, at the same time, separately
Repulsive interaction increases severely between this electromagnet of one end and vehicle mounted electric magnet, exactly prevents the trend that flexible bearing rod is traversing to internal rail, such as
This is also it is prevented that bogie and to take turns opposite internal rail traversing, eventually reduces wheel to the impact and conquassation internal rail, improve
The driving stationarity and degree of passenger comfort of train.
A kind of reduction curve segment of railway from inclining wheel-rail wear device of the invention, preferably solves curve segment of railway from inclining wheel-rail wear
Larger problem can not only be effectively improved rolling stock curve negotiating condition, slow down its wheel-rail wear rate, also in certain journey
The overall stability that orbital curve section is increased on degree is acted on using connection of the device between sleeper, prevents the longitudinal direction of track
It creeps, to improve the stationarity and degree of passenger comfort of train operation.
