Narrow-gauge railway turnout series

Introduction to the series of narrow-gauge railway turnout

The series of switch of narrow track railway in tunnel construction is the key equipment to ensure safety and control speed.The series of narrow-gauge railway turnout is the short-term behavior of temporary engineering.The design should be simple, economical, practical and convenient for maintenance.

Overall design of narrow-gauge railway turnout series

1. The characteristics of narrow rail transport are large snake movement of vehicles, poor operating environment and maintenance of equipment, and easy damage of switch components.For this reason, the straight-line switch switch is adopted in the design. Most of the switches of the switches are interchangeable, which is convenient to replace in an emergency and will not affect production.The width of the groove and the impact Angle and length of the groove are obtained by calculation.

2. Due to the advantages of simple manufacturing and convenient maintenance of the straight line frog, the mutual rail symmetry of the frog, the simplified mutual rail type and the general use of the right and left switch, it has been widely used in China.

3. The whole casting frog consumes precious alloy materials, and the casting process is complex. It can only be manufactured in a professional factory.And common just the manufacturing of a combination of frog is simple, any or the child when a part is abraded or damage, all but repair match, use common rail combination in the design so frog.

Series fault and treatment method of narrow-gauge railway switch

1. Ask the station attendant about the fault phenomenon, and then operate the switch test 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.
