The introduction of ZD6 electric switch machine, the components and functions of ZD6 switch machine

ZD6 series electric switch machine is one of the largest switch machines at present, its purpose is to change the direction of turnout opening, lock the turnout, and reflect the position of the turnout.

ZD6 series electric switch machine use and function.

ZD6 series electric switch machine is one of the main control equipment of China's railway electrical centralized station, and it is widely used in the whole road. Its purpose is to convert electrical energy into mechanical energy and then convert the turnout, changing the opening position of the turnout.

After the sharp rail is closely attached to the basic rail, the turnout is locked in the specified position, and an indication reflecting the position of the sharp rail is given.

ZD6 series electric switch machine model.

zd6-a 165/250、zd6-d 165/350、zd6-e 190/600、zd6-f 130/450、zd6-g 165/600、 zd6-h 165/350、zd6-j 165/600、zd6-k 190/350

ZD6 series electric switch machine features:

DC power supply, rated voltage 160V.

Internally locked, except for ZD6-E, all are extrusionable.

The indication (locking) rod structure is suitable for linkage turnouts, and there are many derivative models, which are suitable for different turnouts.

The main functional components are modular and easy to maintain in the field.

The main structure of ZD6 series electric switch machine.

ZD6 series electric switch machine is composed of nine parts, including motor, reducer, automatic opener, spindle, action rod, indicating rod (or locking rod), displacement contactor ZD6-E type is not currently matched), bottom shell, cover, etc. All of the above parts can be disassembled separately without affecting each other, which is very conducive to maintenance.

ZD6 series electric switch machine working environment.

The atmospheric pressure is not less than 70kPa (the altitude does not exceed 3000m); The ambient air temperature is -40 60 ; The relative humidity of the surrounding air is not more than 90% (25); The surrounding environment is free of harmful bodies, dusts, or harmful gases that corrode metals, or harmful gases and dusts that damage electrical insulation.

ZD6 series electric switch machine according to the requirements of the use of the turnout, the configuration of each model is slightly different, mainly composed of motor, reducer, friction connector, automatic opener, spindle, action rod, indicating rod, displacement contactor, bottom shell and cover.

The splint coupling in the reducer has two functions:

1. The internal gear of the reducer is fixed, and the rotary motion of the pin output mechanism of the reducer is transmitted to the spindle; acres of sedan chairs.

2. When the electric transfer machine is overloaded, if there is a foreign object in the turnout, the output shaft of the reducer will not rotate, and the internal gear can rotate in the splint coupling to protect the switch machine.

The principle of large number turnout on the main line of passenger dedication adopts S700K electric switch machine, and the existing line is consistent with the existing switch machine equipment, and the ZYJ7 electro-hydraulic switch machine is used; Other turnouts generally use ZD6 series electric switch machine.

Function: (1) Convert the position of the turnout, and switch to positioning or reverse position as needed;

2) After the turnout is turned to the required position and is closely pasted, the locking is realized to prevent the external force from converting the turnout;

3) correctly reflect the actual position of the turnout, and the sharp rail of the turnout is closely attached to the basic rail, and the corresponding representation is given;

4) When the turnout is squeezed or is in the position of "four open" (the sharp rails on both sides are not close) for some reason, the alarm and indication will be given in time.

Summary. a) Unlock.

a) Unlock. b) Conversion.

Three) after the locking switch conversion is completed, the locking gear continues to rotate to 339 °, and the starting tooth 7 of the locking gear passes through the tooth groove of the sharpened tines, and the arc surface on the locking tooth annihilation grip wheel coincides with the arc surface of the rack block sharpening the tiny teeth, realizes the locking. At this time, the stop bolt touches the stop hidden pile on the bottom shell, and the locking gear stops rotating.

Hello, I have helped you find the result; ZD6 electric switch machine is a kind of railway signaling equipment, which is used to automatically control the train route switching. In the process of equipment use, extrusion is the friction generated when the switch machine is switched, which will wear out with the long-term use of the equipment, and needs to be replaced and maintained. ZD6 electric switch machine extrusion replacement cycle will be affected by a variety of factors, as follows:

1.Frequency of equipment use: The more the switch machine is used, the faster the extrusion wear will be, and the replacement cycle will be shortened accordingly.

2.Ambient temperature and humidity: In a humid environment, extrusion cuts are susceptible to rust and corrosion, resulting in shorter replacement cycles.

3.Quality and manufacturer selection: The wear resistance of extrusion varies depending on the material and manufacturing process.

Therefore, choosing the best and most durable extrusion cuts can extend the replacement interval. In general, for the ZD6 electric switch machine, it is recommended to carry out maintenance every other year, and regularly replace the extrusion cutting according to the use rate. The specific replacement cycle needs to be evaluated and confirmed according to the use environment and conditions.

In actual use, it is also necessary to regularly inspect the equipment and carry out necessary overhaul and maintenance to ensure the normal operation and service life of the switch machine. I hope I can help you!
