Description
Technical field
The present invention relates to railway traffic equipment, adaptive linkage type is turned up under especially a kind of track with small-radius curve sleeper
Device.
Background technique
The rail traffic cause in China is fast-developing, and the speed of service of train is constantly promoted, high speed, quasi high-speed, quick iron
Largely open operation in road.According to superelevation calculation formulah=11.8v 2 /r, due to train operation speedvContinuous improvement, existing
Minor radiusrSuperelevation value on railway track can not balance the centrifugal force increased by train speed raising, often be passed through using speed limit.Separately
Outside, superelevation setting will lead to wheel-rail force increase, aggravation track side abrasion with actual vehicle speed mismatch, seriously affect the fortune of train
Defeated efficiency, degree of passenger comfort and route service life.Sharp radius curve section train running speed how is improved, wheel-rail wear is reduced
Rate improves train operation quality and is of great significance for expanding railway transport capacity.
In order to improve train curve negotiating condition, slows down wheel-rail wear rate, improve train running speed, China is wide at present
There are mainly two types of the methods of general use.First is that sharp radius curve is reconstructed as sweeping curve by engineered.In setting phase
Under same superelevation value, increases sweep, train passage speed can be effectively improved.However, China sharp radius curve section quantity
Numerous, this method consuming time is longer, will affect the operation of normal rail track.In addition many manpowers, wealth will also be expended
Power, material resources.Second is that reaching raising train by the pendulum that inclines automatically of vehicle body using pendulum train come the influence of equilibrium centrifugation power
The comfort level of passage speed and passenger.This method can improve the passage speed of train to a certain extent, but in pendulum-type
Finger tilt device is added in train suspension system, can aggravate train unsprung mass, causes to increase the percussion of rail flowering structure.
Summary of the invention
It is an object of the invention to provide one kind can effectively slow down wheel-rail wear rate, extends transporting equipment and uses week
Phase increases adaptive linkage type height-regulating device under the track with small-radius curve sleeper of curve track overall stability.
Adaptive linkage type height-regulating device under track with small-radius curve sleeper of the invention, including sleeper, shell, control system
System, which is characterized in that be fixedly connected by bolt with rest pad below sleeper internal rail track, the two sides of rest pad are installed with bolt
Pulley blocks fixed plate, leading block are assembled in pulley blocks fixed plate, and the pulley in leading block group is embedded in the arc of frid
In slot, frid is installed in the lower support plate of housing bottom；The bottom of sleeper outer rail track end is equipped with pulley groove and pulley plate
Slot, pulley plate are placed in pulley board slot, in the pulley insertion pulley groove of pulley plate inner end two sides, in the middle part of pulley plate inner end and are hung down
Directly it is connected to hydraulic arm, is vertically bolted to sleeper upper surface to hydraulic arm；The following table of plate and pulley plate is lifted on lifting platform
Face paste is closed, and blending bolt is fixed, and plate is lifted under lifting platform and is connected by X-type rod piece with lift plate on lifting platform, X-type rod piece hinged-support
Respectively with outer end in plate is lifted under lifting platform, lift plate outer end connect on lifting platform, lift plate inner end is pulley on X-type rod piece and lifting platform
Connection, Multi-direction fluid pressure arm one end are fixed under lifting platform and lift on plate, and the other end is affixed by guide rod and X-type rod piece, and pushes X-type
Rod piece moves, and lift plate is bolted in lower support plate under lifting platform.
Adaptive linkage type height-regulating device working principle is under track with small-radius curve sleeper of the invention, when outside is tested the speed
System obtains travel speed of the train by curve, and system calculates outer rail track superelevation value immediately, and control system is according to superelevation
It is worth and is filled with corresponding required The hydraulic oil into Multi-direction fluid pressure arm, Multi-direction fluid pressure arm starts elongation and guide rod is pushed to link X-type bar
Part longitudinal movement, Multi-direction fluid pressure arm is persistently extended and is rotated around hinged-support during movement.Plate is lifted on lifting platform starts propelling sheave
Plate and sleeper are lifted upwards, tilt, and keep horizontal due to lifting plate on lifting platform, have with pulley plate lower surface and generate crack angle
Trend, vertical hydraulic arm work at this time pulls pulley plate, moves pulley in longitudinal pulley groove, so that pulley plate be made to tilt one
Determine angle, is in close contact lift plate upper surface on lifting platform with pulley plate lower surface always.At the same time, targeting part is to guarantee
Interior rail rail surface centre-height is constant, and the guide runner of frid and the arching trajectory of leading block group are with rail rail surface center in sleeper block
For the center of circle, since pulley blocks fixed plate is bolted on rest pad two sides, leading block group is embedded in guide runner, leads
Length travel to part is restrained, and leading block group can only be rotated with both fixed tracks, thus rail rail surface centre-height in guaranteeing
Constant, oil cylinder locking after lifting is completed in the lifting of outer rail stress.
The advantages of adaptive linkage type height-regulating device, is embodied in following aspect under track with small-radius curve sleeper of the invention:
1, superelevation set-up mode is " rail rail surface centre-height is constant in keeping, and outer rail is raised ", this and the most of sharp radius curves in China
The superelevation set-up mode in section is identical, is conducive to be laid on existing railway track.2, target object is single independent rail
Pillow, can accurately be arranged superelevation to sleeper any number of on curve track, so that its effect on transition curve path section is opposite
Possess stronger adaptability and more accurate easement curve line style in the superelevation regulating device with " track plates " for basic structure.3,
When superelevation is set as unit of independent individual sleeper, it can prevent track difference in height during lifting from uprushing, avoid bending,
It is more advantageous to protection track.4, using the hydraulic cooperation with electromechanical assembly on power, energy consumption aspect is far smaller than pendulum train
Required additional energy.
