Description
Technical field
The utility model 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
The purpose of this utility model, which is just to provide one kind, can effectively slow down wheel-rail wear rate, extend making for transporting equipment
With the period, increase the overall stability of curve track, improves the reduction railway curve of train operation stationarity and degree of passenger comfort
Section wheel-rail wear device.
A kind of reduction curve segment of railway from inclining wheel-rail wear device of the utility model, including drop wheel-rail wear ontology, stretch and hold
Power bar, which 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 uses anchor bolt
It is fixed, it drops and is provided with groove in the middle part of wheel-rail wear ontology direction along ng a path, be respectively mounted on the drop wheel-rail wear ontology of groove two sides
There is ontology electromagnet, the circuit controling element of control ontology electromagnet is located in drop wheel-rail wear ontology；Flexible bearing rod installation
It is fixed in bogie, its underpart movable end is equipped with vehicle mounted electric magnet, and stretch load pole length retractable, vehicle mounted electric magnet
With flexible bearing rod stretch out when insertion drop wheel-rail wear ontology in the middle part of groove in, the both ends polarity of vehicle mounted electric magnet with adjacent
The polarity of body electromagnet is identical.
A kind of reduction curve segment of railway from inclining wheel-rail wear device of the utility model, utilizes electromagnet homopolar-repulsion, heteropolar phase
The principle of suction, by controlling the work of electromagnet, by the repulsive interaction between drop wheel-rail wear ontology and flexible bearing rod, in real time
Position of the flexible bearing rod in drop wheel-rail wear body recess is adjusted, is in it at groove center line always, meanwhile, it stretches
Bearing rod also will drive bogie and wheel to making synchronous cross movement, so that there is gap between certain trip between wheel track always, from
And reduce the impact and abrasion between wheel track.The specific working principle is as follows is for it, train i.e. by arrival curve section when, signal system
Start to control flexible bearing rod inside bogie to extend automatically, at the same time, ontology electromagnet and vehicle mounted electric magnet are started to work,
Behind train 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 sheet
Among the groove of body, 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,
It being influenced by centrifugal force of train, bogie and wheel are traversing to outer rail generation to will drive flexible bearing rod, at the same time, one end ontology
Repulsive interaction increases severely between electromagnet and vehicle mounted electric magnet, exactly prevents the trend that flexible bearing rod is traversing to outer rail, so also
It prevents bogie and the opposite outer rail of wheel traversing, eventually reduces wheel to the impact and abrasion outer rail；When curve track mistake
When superelevation, by train self weight component influences, bogie and wheel are traversing to internal rail generation to will drive flexible bearing rod, same with this
When, repulsive interaction increases severely between this electromagnet of the other end and vehicle mounted electric magnet, and flexible bearing rod is exactly prevented to become to internal rail is traversing
Gesture, so also it is prevented that bogie and to take turns opposite internal rail traversing, eventually reduces wheel to the impact and conquassation internal rail, mention
The high 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 utility model, preferably solves curve segment of railway from inclining wheel track
Larger problem is worn away, rolling stock curve negotiating condition can not only be effectively improved, slows down its wheel-rail wear rate, also one
Determine the overall stability for increasing orbital curve section in degree, is acted on using connection of the device between sleeper, prevent track
Longitudinal direction is creeped, to improve the stationarity and degree of passenger comfort of train operation.
