Description
Technical field
The invention belongs to the assembling equipment technical fields of turnout curve tongue, and in particular to a kind of group of turnout curve tongue
Close structure.
Background technique
With the continuous development of present science and technology, economic field, it is that one kind makes rolling stock from one that track switch, which belongs to rail switch,
Station track is transferred to one of the line connection equipment of another station track and the weak link of track, and usually AT STATION, marshalling yard largely spreads
If.There is track switch, the handling capacity of route can be given full play to.Even single-track railway, laying a switch builds one section and is greater than column
The cross wires of vehicle commander's degree, so that it may split train.Track switch plays an important role on rail track.
But since track train is when turning to, need that track switch, train driving to track switch is arranged in the guide rail side of straight trip
When position, under the draw of point tongue, directly slided on the track drawn to point tongue from original track,
But point tongue is generally positioned between guide rail there are gap so that track train staggeredly traveling transient process in, vehicle
Wheel when passing through railway frog, the most narrow place of Cong Lianggen wing rail to frog centre it is most advanced between have one section of gap, wheel passes through herein
When, it is possible to cause to derail because going to the wrong way frog flangeway.So guard rail generally is arranged in railway frog position, its purpose is to mandatory guidances
The traffic direction of wheel.Nevertheless, this idle space, which exists, limits speed of the train by track switch, arrange high speed is started
Vehicle is very unfavorable, and there is sense of jolting.
