Railway Turnout

Mine Turnout is a way for rolling stock from one track to another round after round into line connection device, usually large laying at the station, marshalling station. With mine turnout, can give full play to the line passing ability. Even the single-track railway, laying turnouts, the construction period is greater than the length of the fork train line, you can mine coal car off.
Single turnout features: single turnout because there is more than the number of complex structures, life is short, limiting train speed, low traffic safety, maintenance and repair of investment and other characteristics, and curve fitting and called the orbit of the three major weaknesses.

Single turnout contains rail switch, guard rail and connecting portion and sleeper components.Rail switch is used to guide the locomotive turned from positive line lateral line lateral line or the line is turning the steering equipment; rut fork and guard rail is to make the wheels of locomotive rail crossed by a stream of another unit of the transition rail equipment; switching point and the rut bifurcated by a connecting portion. Derailleur by a pair of sharp track, a pair of basic track, switch and lock and composed of several connected parts.Switch and lock, also known as switchman, and the turnout from the gates seat presenter, rod, turn lever, etc., since the operation of the switch rail turnouts swing around and changing the opening direction. Set in turnout turnout frog lateral line rail intersection with the main line rail, guard rail located on both sides of fork rut. Rut bifurcated by the wing rail and fork heart composed wing rail is bent fork heart next to the two rails, wheel out of the fork is the heart of the transition device. Heart fork angle between two sides work, called frog angle, angle cotangent frog frog called number. Connecting part of the role is to connect derailleur and rut fork, he has a direct stocks and shares two curved parts, direct shares and ordinary straight lines as curved stocks generally circular curve, also called conduction curve.

Crossover Track Switch many times, is called narrow gauge rail line, mine crossing the line switch. Narrow Gauge Crossover Track Switch is our country coal system USES special railway switch, is narrow track rail lines connecting the basic equipment. Crossing the line switch in mine construction and production of plays an important role, this kind of rail laying convenient, quickly, has the strict manufacture, acceptance criteria, the rail type, gauge, series of switch Angle, is applicable to coal mine industry in our country and changeable usage.
Crossover Track Switch Composition Instruction

（1）Model is the first letter Z represents the narrow gauge railroad switch type code;
（2）The second and third letters, DK, DC, DX, JD, DZ, JC, TX represent the single open, symmetric, crossing the line, cross line, combination, diamond crossing, four rail line switch type.
（3） The main parameters of the first paragraph number 6, 7, 9, respectively, on behalf of the rail track, 6 = 600, 7 = 700, 9 = 700 mm, the main parameters of the first paragraph number 15,22,30,38,43, represent the switch rail, kg/m.

1. Understand the rail failure condition
First ask station attendant fault phenomenon, then on the console control switch test.
3. Registration switch stop using equipment
4. Determine the cause of the switch is indoor or outdoor

(1) If it is a single switch, ammeter has instructions to the console when operation, stating that the motion switch power is sent to the switch. If the switch can’t speak to the specified position, it is outdoor. When operation switch, if the console ammeter without instructions, first of all to the machinery room outside plate of measurement have the switch voltage, if has motion switch electric voltage specification has been sent out, is outside the fault.
(2) If it is double acting switch, when the operation console the ammeter and I don’t move, stating that the motion switch power is sent to the move switch, failure after move switch, is outside the fault.
(3)If the yard can operation, trans, is not said. The multimeter ac 250 v, measure X1 X2) (or in line set between the X3 and presence of ac 110 v voltage, if there is a voltage, is outside the fault, it is indoor fault.

Railway Track Turnout can be divided into single turnout, double turnout (equilateral turnout), three turnout (three-way turnout) and multi-turnout (Double Slip Switches), etc.
Y-shaped equilateral turnout, which dovetail with the turnout to the sides of the two stocks Road bifurcation.
Three-way Railroad Switch as Ψ-shaped, while convergence of three tracks, mechanically operated by two sets of sharp turn rut track.
Double Slip Switches like X-shaped, in fact, equivalent to four single turnout and a diamond-shaped cross combinations.
In addition, there is a cross-connect equipment, usually called diamond cross. It consists of two acute and two obtuse frog frog composition, but no derailleur, so the shares can not be transferred between road line.
If the Double Slip Switches X-shaped two points above and below the two are connected together, that crossover. It can not only open more direction, but a small space, so often used at the station.

1.Railroad Switch installed device fixed screw fastening, device without the old wound crack.
2. Each connecting rod, lock device outside the old wound crack, bar mill card and corrosion, abrasion pin hole is not greater than 1 mm, good insulation.
