Description

Track with small-radius curve hydraulic lever type superelevation sleeper
Technical field
The utility model relates to railway traffic equipment, especially a kind of track with small-radius curve hydraulic lever type superelevation rail Pillow.
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
The purpose of this utility model is just to provide a kind of curve passage speed that can have not only increased substantially train, but also can be effective Uneven centrifugal force bring is avoided to cross superelevation and deficient superelevation phenomenon, thus reduce the wheel-rail wear rate of sharp radius curve section Track with small-radius curve hydraulic lever type superelevation sleeper.
The track with small-radius curve hydraulic lever type superelevation sleeper of the utility model, 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;It is installed on bearing by bolt the bottom of sleeper outer rail track end Fixed plate, bearing bottom plate are fixedly connected with bolt with bearing upper mounted plate again, and bearing is arranged in bearing upper mounted plate and axis It holds between bottom plate, guide rod is connected with two bearings for being symmetrically mounted on sleeper two sides, and is positioned by nut, gasket, leads The diameter of bar middle part small in ends is big, and for constraining the displacement of bearing interior direction, the interlude of guide rod connects a pair of of hydraulic arm, liquid Another union end of pressure arm is fixed on bearing plate with hinged-support.
The working principle of the track with small-radius curve hydraulic lever type superelevation sleeper of the utility model is that the present apparatus needs outer Portion's power drives, when external velocity-measuring system obtains travel speed of the train by curve, system calculates outer rail track superelevation immediately Value is filled with required The hydraulic oil into hydraulic arm according to superelevation value external motor, and hydraulic arm starts elongation and pushes guide rod upward Lifting, since the rotation of sleeper, hydraulic arm can generate rotation around lower hinge point during elongation, guide rod generation appropriateness is axial to be turned It is dynamic, it is rotated by bearing inner shaft and bears torque, guide rod drives shaft strength to act on and apply pressure to bearing upper mounted plate and sleeper, sleeper Outer rail part starts to raise inclination.At the same time, targeting part is that rail rail surface centre-height is constant in guaranteeing, the guide runner of frid Arching trajectory with leading block group is using rail rail surface center in sleeper block as the center of circle, since pulley blocks fixed plate is solid by bolt Rest pad two sides are scheduled on, leading block group is embedded in guide runner, and the length travel of targeting part is restrained, leading block group It can only be rotated with both fixed tracks, so that rail rail surface centre-height is constant in guaranteeing.External power supply is closed after completing lifting, oil cylinder lock It closes, hydraulic arm is locked.
The track with small-radius curve hydraulic lever type superelevation sleeper of the utility model, 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.
