Description
Technical field
The present invention relates to railway traffic equipment, the automatic superelevation dress of especially a kind of wheel dynamic formula sleeper for curve track
It sets.
Background technique
China's transportation business is quickly grown in recent years, and the speed of service of train is constantly promoted, high speed, it is quasi high-speed, fast
Fast railway largely opens operation.However weak link of the sharp radius curve as rail track, it restricts train always and passes through song
The speed of service of line.Train on sharp radius curve when driving, since the effect of uneven centrifugal force will affect train operation
Safety and stationarity, are often passed through using speed limit, and the transport capacity of train and the comfort of traveller's are seriously affected.How
The speed of service of the train by sharp radius curve is improved, for expanding railway transport capacity, improving train operation quality has weight
Want meaning.
In order to improve train in the passage condition of sharp radius curve section, train running speed is improved, China is adopted extensively at present
There are mainly two types of methods.First is that being reconstructed by engineering, sharp radius curve is reconstructed as sweeping curve.It is calculated according to superelevation
Formulah=11.8v 2 /r, identical superelevation value is being sethUnder, increase sweep valuer, can effectively promote the current speed of train
Degree.However, China's topography is more complex, sharp radius curve section is large number of, and this method consuming time is longer, will affect normal
The operation of rail track.In addition many manpowers, financial resources and material resources will also be expended.Second is that being existed by vehicle body using pendulum train
The pendulum that inclines automatically of curve section carrys out the influence of equilibrium centrifugation power.Although this method can improve the logical of train to a certain extent
Scanning frequency degree, but finger tilt device is added in pendulum train suspension, train unsprung mass can be aggravated, is caused to rail flowering structure
Percussion increase.
Summary of the invention
It is an object of the invention to provide a kind of curve passage speeds that can improve train, effectively avoid uneven centrifugal force
The automatic overheight attachment of wheel dynamic formula sleeper for curve track for bringing superelevation and deficient superelevation to endanger.
The automatic overheight attachment of wheel dynamic formula sleeper for curve track of the invention, including sleeper, shell, control system,
It is characterized in that, being fixedly connected by bolt with rest pad below sleeper internal rail track, the two sides of rest pad are installed with bolt to be slided
Wheel group fixed plate, leading block group are mounted in pulley blocks fixed plate, and the pulley in leading block group is embedded in the arc of frid
In slot, frid is installed on the bearing plate of housing bottom；The bottom of sleeper outer rail track end is fixed with screw and backing plate, branch
Bearing column is bolted on backing plate and sleeper, and support column inner and outer ends are respectively equipped with internal tooth and pawl, support column internal tooth with
The power output gear of motor group engages, and motor group is fixed on bearing plate；Release link is fixed by bolts on bearing plate,
For reseting spring sleeve in release link, support rod bottom is fixed in the upper end of reset spring, and the lower end of reset spring and release link are solid
It connects, the lower part of support rod covers in release link, and support rod carries out longitudinal sliding motion, support rod two sides by release link, reset spring
Hydraulic wedge block be fixed by bolts on bearing plate, support rod and hydraulic wedge block wedge contact；The upper end of support rod
Resist the outer end pawl of support column.
The automatic overheight attachment working principle of wheel dynamic formula sleeper for curve track of the invention is that the present apparatus needs external electrical
Source driving, once external velocity-measuring system obtains travel speed of the train by curve, system calculates outer rail track superelevation value immediately,
External motor starting, hydraulic oil drain valve open, and hydraulic wedge block is separated to two sides, and support rod is under by reset spring and Gravitative Loads
It moves, is separated with the pawl on support column.Motor group band moving gear rotates, gear again on support column internal tooth (support column it is interior
Tooth distribution trajectory be within rail rail surface center be the center of circle arc segment) engagement to drive support column, backing plate, sleeper lifting.Lift
After rising, hydraulic valve fuel feeding pushes hydraulic wedge block to squeeze inwardly until support rod resists the pawl of support column, and motor closes
It closes；At the same time, targeting part is that rail rail surface centre-height is constant in guaranteeing, the guide runner of frid and the arc of leading block group
It, since pulley blocks fixed plate is bolted on rest pad two sides, is led using rail rail surface center in sleeper block as the center of circle track
It is embedded in guide runner to pulley blocks, the length travel of targeting part is restrained, and leading block group can only be turned with both fixed tracks
It is dynamic, so that rail rail surface centre-height is constant in guaranteeing.
The automatic overheight attachment of wheel dynamic formula sleeper for curve track of the invention, as unit of independent single sleeper,
The height value of the outer rail rail surface of sleeper is adjusted in real time by the velocity-measuring system outside sleeper, computing system, feedback system
The superelevation value to be matched with train by curve speed, advantage are embodied in following aspect: 1, superelevation set-up mode is " in holding
Rail rail surface centre-height is constant, and outer rail is raised ", the superelevation set-up mode phase of this and the most of sharp radius curve sections in current China
Together, it thus can be laid immediately on existing sharp radius curve section, project amount is small, laying is convenient；2, target object is single
Superelevation can be accurately arranged to sleeper any number of on curve track, so that the work on transition curve path section in independent sleeper
Possess stronger adaptability and the higher mitigation song of precision with relative to the sleeper overheight attachment that " track plates " are basic structure
Line line style；3, when reaching superelevation as unit of independent individual sleeper, it can prevent track from generating bending during lifting, have
Conducive to protection track；It is supported on power using electromechanical assembly and hydraulic coupling, is far smaller than needed for pendulum train group in terms of energy consumption
Additional energy.
