Crossover Track Switch Alias: many times,it 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.
（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.
2.Registration switch stop using equipment
3.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.
