Abstract
The utility model discloses a symmetrical three throw turnout, for incorgruous asymmetric symmetrical three throw turnout, including fixed curved frog of first railway switch, second railway switch, first fixed curved frog, second and the fixed curved frog of third who sets gradually. Fixed curved frog side fork is not the symmetric distribution, but the distribution of staggering around being, so that the switch blade closed angle can set up is great, and the rail head section broad of same position, therefore can increase switch blade intensity, increase of service life. Fixed curved frog is used for directly to current heart rail for sharp for heart rail that the side direction is current be the curve, and the current heart rail radius of side direction has just so lengthened the length of leading curve rail in other words, thereby just can improve radius of lead curve under the condition of the present field circuit of standing with to lead the curve rail radius the same, passes through speed, improvement conveying efficiency with improvement train side direction.
Description
Technical field
The utility model relates to a kind of railroad track linkage, particularly relates to a kind of three-throw turnout.
Background technology
Track switch is the basic linkage of one of railroad track, and the track switch that Ministry of Railways's " conventional track switch major parameter handbook " includes is divided into simple turnout, bilateral turnout, double slip swich, double crossover track switch.Three-throw turnout refers to the track switch of leading to three directions from a direction, three-throw turnout belongs to the one of special track switch, when the circuit needing to connect is more, and landform is restricted, on main line, just can not adopt three-throw turnout when continuous laying two simple turnouts, usually lay in marshalling yard, goods yard, locomotive depot.The three-throw turnout two side direction walking rail of current application is relatively straight symmetrical to walking rail center line, so also known as symmetrical three-throw turnout.This three-throw turnout, because railway switch being arranged two pairs of tongues simultaneously, four point of switch alignment, side direction tongue is near directly to tongue, and point of switch angle is less, and thus tongue intensity is not high, easily weares and teares, and assembling difficulty is larger.And, the stiff frog that existing three-throw turnout adopts is all straight line railway frog, namely two radical center rails are all straight line, lead curve rail is connected to the head end of straight line railway frog, the track switch of this structure, and lead curve is short, radius is little, therefore side direction allows that Negotiation speed is slower, as 50kg/m rail No. 7 jog radiuses are 150m, can not be greater than 30km/h laterally through speed, like this, also have impact on conevying efficiency.Existing three-throw turnout, because there is above-mentioned technological deficiency, so do not promote the use of, is not even included into " conventional track switch major parameter handbook ".
