Series of narrow-gauge railway turnout for mine

Introduction to the series of track forks for mine narrow rail (rail 8kg/m-30kg/m fork no. 3-12)

The standard design for the track of mine narrow rail railway has a total of 615, 715, 915, 622, 722, 922, 630, 730, 930, 938 and 643 series, and the design has completed a total of 166 varieties.

Description of the composition of the track series (rail 8kg/m-30kg/m fork no. 3-12) for the mine narrow rail rail

(1) model letter Z stands for the type code of narrow-gauge railway turnout;

(2) type two and three letters, DK,DC,DX,JD,DZ,JC and TX represent the type code of single open, symmetrical, crossing, crossing, symmetrical combination, diamond crossing and four-rail sleeve line switch respectively.

(3) the Numbers 6, 7, 9 and 9 in the main parameters represent the track of the turnout, 6= 600,7 = 700,9 =900mm, and 15,22,30,38,43 in the main parameters are respectively, kg/m.

Basic knowledge of track series (rail 8kg/m-30kg/m fork no. 3-12) for mine narrow rail rail

Turnout is a large family, the most common is the general single switch.It is made up of switch, connection part, frog and rail.The switch consists of a basic track, a pointed track and a switch machine.

Fault and treatment method of mine narrow rail rail switch series (rail 8kg/m-30kg/m fork no. 3-12)

1. Understand the switch failure

First, the station attendant is asked about the fault phenomenon, and then the switch test is conducted on the control platform.

2. Register the turnout stop equipment

3. Determine the cause of the switch

Switch switch switch switch switch switch switch switch switch switch switch switch switch switch switch switch switch switch switch switch switch switchIf the switch cannot be operated to the designated position at this time, it is because it is outside.When operating a switch, if the console ammeter does not indicate, first measure whether the switch has a voltage on the outdoor dividing plate of the machine room.

If you are a double switch, the ammeter in the console will not move when the switch is operated, indicating that the electric power of the action switch has been sent to the moving switch, the fault is out of the room after the moving switch.

If the switch is fixed and the opposite can be switched, there is no indication.Ac 250v of multimeter is used to measure the voltage between X1(or X2) and X3 with or without an alternating current of 110V. If there is a voltage, it is an outdoor fault; otherwise, it is an indoor fault.
