The utility model can ensure high-speed running vehicles to realize continuous support without impact vibration and shake, and can increase the speed of trains, which is favorable to the promotion of the rapid development of high-speed railways.
Description
The present utility model has designed a kind of novel high speed railway switch.
The railway frog of existing common railway track switch is fixed (as Fig. 1).Owing to have idle space at the frog centre place, be that each direction all is reserved with the wide seam that the traveling of wheel guiding wheel rim is passed through, when making the idle space of railroad train wheel by the track switch frog centre be wide seam place, discontinuous because of supporting, and very strong impact shock appears, make train at a high speed by the time powerful rocking can take place.In addition, the guard rail that is provided with at the idle space position, can produce very big lateral pressure to the train that passes through at a high speed, consequent horizontal force, not only may cause track deformation, cause track and rolling stock to damage, worsen riding comfort, and jeopardize traffic safety, therefore greatly limited the speed of service of railroad train.What existing acclerating road switch of China and international existing common high-speed railway switch adopted all is the railway switch (as Fig. 2) of rotary type movable-point crossing.The railway frog of this track switch is by wing rail 24, movable point frogs 27, form with fork-shaped piece 30 3 parts, the railway frog front and back end is provided with rail overlapping device, to eliminate track creeping and influence of temperature variation, the relative position that guarantees movable point frogs and wing rail is constant, during the movable point frogs conversion, the movable point frogs rear end is along fork-shaped piece lateral sliding, movable point frogs front end edge pivoted is also closely connected with the wing rail of a side, eliminated the idle space of common railway track switch stiff frog, make train low speed by the time do not have impact shock and rocking, operate steadily, when train middling speed and quasi high-speed following speed operation are passed through, impact shock and rock lessly, operating ratio is more steady.But during the common high-speed railway switch of railroad train high-speed cruising by existing rotary type movable-point crossing, rotation conversion because of the rotary type movable point frogs, what make that the handing-over line (face) of movable point frogs and fork-shaped piece forms is a bigger angle of cut line (face) that interruption is arranged that can not be really continuous, rather than forms the straight line (face) and the curve (face) of straight line (face) or rounding off.The wheel of bullet train taper tread will produce bigger impact shock by this rotary type movable head track switch place and rock, and has limited the speed of service of the bullet train of high-speed railway.Again because rotary type movable head track switch is more much longer than common track switch, in the technological transformation of existing railroad train speed-raising, the not general The reconstruction scope that makes of track switch before and after changing enlarges, construction costs increases, this railway, the installation of track switch, build, use, maintenance, technological transformation, renew and the difficulty of detection etc. very big, its main shortcoming is that the rotary type movable center points is when pulling railway switches, movable point frogs is along pivoted, slipper slides on the fork-shaped piece, make the fork-shaped piece to producing varying stress repeatedly between the slipper of movable point frogs and the pivot, make the slipper of movable point frogs and the place of joining of pivot produce early fatigue rhegma even fatigue break easily, reduce the application life of this track switch greatly, increase cost of railway traffic, particularly very easily cause the great traffic safety accident of railway traffic transportation, the personal safety and the property safety that jeopardize railway passenger.
The purpose of this utility model is to produce powerful impact shock to common railway track switch stiff frog heart place because of discontinuous supporting for solving train operation; Impact shock and rock bigger when the movable point frogs that solves the common high-speed railway switch of rotary type movable-point crossing exists discontinuous, the not slick and sly big angle of cut that bullet train is moved with the fork-shaped piece; It is general and make further technological transformation and maintenance difficulty such as renew to solve long and the existing common track switch of rotary type movable point frogs railway switch; With solve the rotary type movable center points when pulling railway switches, the fork-shaped piece produces varying stress repeatedly to movable point frogs slipper and pivot merge point, cause the early fatigue rhegma, even fatigue break, be difficult to avoid the technology hang-up of four aspects such as railways train operation serious accident.A kind of novel high speed railway switch (as Figure 10) is provided.The utility model can guarantee that bullet train does not have impact shock fully and rocks because of what supporting continuously realized, guarantees bullet train safety and steady ground high-speed cruising on novel high speed railway and novel high speed railway switch when the operation of this novel high speed railway switch place.
The purpose of this utility model is to realize like this, according to the novel high speed railway trouble (the novel high speed railway switch of flatly moving type movable-point crossing) (as Figure 10) of mathematical theory and mechanics principle invention design, by the wing rail (as Fig. 4) that is " X " type flatly moving type movable-point crossing, the movable point frogs (as Fig. 6) that is " Δ " type flatly moving type movable-point crossing, the transition rail (as Fig. 8) that is " protruding " type flatly moving type movable-point crossing, the goat 6 of closed system with lock, turn-out track can be adjusted connecting rod 7, turn-out track locking bar 8, the parallel sliding guidance system of flatly moving type movable point frogs (guide peg bolt 15 and guiding slide mass 11), stock rail 1, tongue 2, rail 3, guide rail 4,12 parts such as backbone 5 grades are formed.The equidirectional coordinated type of connecting rod promotes frog centre and tongue moves to the solid arrow or the empty direction of arrow when the track switch goat can be adjusted at electronic computer center monitoring chamber control lower-pilot changing points, the frog centre parallel sliding of movable-point crossing and a side of wing rail are closely fitted, simultaneously the stock rail of tongue and the same side is closely fitted, finish the purpose of changeing the line task thereby reach.At this moment the novel high speed railway switch does not have smooth-going stock rail, tongue, guide rail, rail wing, railway frog movable point frogs, railway frog transition rail, rail, the backbone that connects the novel high speed railway switch sleekly of interruption continuously on the railway line of whole high-speed railway.Thereby make novel high speed railway switch on whole railway lines of novel high speed railway form rounding off continuously supporting no impact shock and do not have the novel high speed rail track that rocks, guaranteed bullet train on high-speed railway, do not have impact shock, do not have rock the ground safety and comfort, steadily at high speed by the novel high speed railway switch.
Can guarantee the steady high-speed cruising in bullet train no impact shock ground on the novel high speed railway switch owing to adopt such scheme.
