Description

Rotating-axial superhigh switch on railway
Technical field the utility model relates to a kind of railway switch, and particularly a kind of rotary shaft that helps improving road speed has the railway switch that superelevation is provided with.
The frog centre of the common railway track switch that background technology is used now exists wheel along groove, that is to say between the track switch that two strands of railways intersect one section space is arranged, be referred to as " idle space " in the industry of this section space, Train Wheel by the time " jumping car " phenomenon such as jolt, shake, wave, and track switch to damage application life easily low.Owing to the shared railway frog point of two-way driving (wheel is along groove) superelevation can't be set, therefore, train driving has the speed limit requirement, is generally 75km/h or 45km/h.
The movable head track switch of Japan is mainly used in high-speed railway, also is because the shared railway frog of two-way driving is sharp superelevation to be set, and limited train speed to a certain extent, and area occupied is long especially.Its movable head part steering angle is little, but pivoted arm is long especially, and rotational stiffness is big, the cost of production height.
Utility model content the technical problems to be solved in the utility model provide a kind ofly improve road speed and stationarity, improve track switch and wheel application life, rotating-axial superhigh switch on railway that area occupied is little.
In order to solve the technical problem, the technical solution adopted in the utility model is: a kind of rotating-axial superhigh switch on railway comprises direct movement rail, rut movement rail, direct movement tongue rail, rut movement tongue rail, frog centre and frog rail is characterized in that: frog centre is made of transition, slide plate; Slide plate fixedly is loaded on above the sleeper, and position corresponding with the frog rail tip on the slide plate is provided with axial trough; One end of transition is provided with the down inserting type rotating shaft, this rotating shaft and axial trough are rotatably connected, and the other end of transition is a free end, and free end docks with the direct movement tongue rail afterbody or docks with the rut movement tongue rail afterbody, the bottom of transition is provided with stretches out handle, and the driving rail level of transition is craspedodrome rail level and a rut movement rail face straggly.
Because the driving rail level of transition is provided with two driving rail levels straggly, difference in height between craspedodrome rail level and the rut movement rail face constitutes " superelevation ", so just the rut movement rail outer rail can be arranged to exceed one section progressive, superrelation on curve than interior rail, the rut movement rail face of transition forward and backward respectively with rut movement tongue rail and angle rail (frog rail) along connecing.Thereby, can guarantee further that train operation is steady, improve the speed of a motor vehicle.The superelevation height is determined according to speed limit and curvature.To improve the speed of a motor vehicle and running stability.
Can also give perfect to described rotating-axial superhigh switch on railway: in the left and right sides of slide plate, with the corresponding position of transition baffle plate is set, the baffle plate inboard be provided with and the corresponding caulking groove of the side view of going through transition, to guarantee enough lateral support.
The utility model is to change the existing track switch fork heart into rotating shaft, between tongue afterbody and railway frog axle center, add one section transition, by the switching between the transition free end is outside two tip of a root rail afterbodys, realize turning to of track switch (driving), transition length can be selected according to the size of track switch number, and principle is that baffle plate does not disturb wheel to advance.Transition is converted into the small rail gap of twice with original " wheel is along groove ", and has eliminated the hidden danger of " skidding off track ".
The utility model has solved the superelevation setting of track switch and wheel along " jumping car " phenomenon of groove.
The utility model and common track switch are compared: eliminated " wheel is along the groove " of common track switch, improved road speed and stationarity, improved the application life of track switch.Original " wheel is along groove " is converted into the small rail gap in two places, eliminates the hidden danger of " skidding off track ".The roar when greatly reducing train and the sense of jolting by track switch, the application life of having improved track switch and wheel.Rotating shaft of the present utility model is a down inserting type, and inserting the axle diameter of axle down can be consistent with transition seating plane width, has enough shear strengths and rigidity to guarantee rotating shaft.
The utility model compares with the movable head track switch and the old-fashioned track switch of Japan: the utility model is provided with certain " superrelation on curve " on rut movement rail-transition and the capable section of angle rut, increase substantially driving maximum speed limit standard and stationarity.Movable head track switch is only applicable to the ultra-large type track switch more than No. 38, takes up an area of length, and does not have superelevation; The utility model is applicable to all number track switches, under identical speed limit situation, little many of number level of the present utility model, and reduced occupation of land length, movable head track switch will be used potassium steel, the utility model track switch need be with the potassium steel except that transition, and all the other all can use the steel of old-fashioned track switch, but track switch cost first mate degree reduces.Movable head track switch is not owing to there being the axle center, to the power requirement height of driving force machinery; The utility model track switch is a rotary shaft, driving force is required not quite, with identical the getting final product of existing common tongue transmission device.
