I General introduction of sliding plug door

Since the introduction of sliding doors in China in the mid-1990s, after digestion and absorption, domestic sliding doors have been widely used in the side doors of fast passenger trains in China, including manual, electric, left opening and right opening. At present, China's 25 type bus plug-in door usually adopts manual plug-in door and electric pneumatic plug-in door. The driving mode of electric pneumatic plug-in door is pneumatic and the control mode is electric control, which can realize the control of this vehicle and the centralized control of train automation; The manual sliding plug door is powered by hand, and the sealing force is increased by the pressurizing device, which can not realize centralized automatic control. Now, with the continuous improvement of the performance of the selagine control system, the automatic door system of the sliding plug door has replaced the manual door system. At present, most fast trains use the electrically controlled pneumatic sliding plug door.

According to the power mode, the sliding plug door can be divided into: manual sliding plug door, pneumatic sliding plug door, electric sliding plug door and electric pneumatic sliding plug door.

According to the shape of door panel, it can be divided into flat door and bow door.

At present, the passenger cars equipped in our section are electrically controlled pneumatic sliding plug doors and manual sliding plug doors.

There are mainly four types of electrically controlled pneumatic plug doors: (1) bode (2) Connie (3) oterme (4) Yifei

Manual sliding doors are mainly divided into the following two types: (1) bode (2) Connie

Advantages of sliding plug door: good sealing, no occupation of interior space, scientific design, safety and reliability, automatic operation and centralized control of all train doors

Disadvantages of sliding plug door: poor antifreeze performance, short service life of most parts, high cost, complex structure, easy failure and difficult maintenance

The sliding plug door is a series of outward swinging sliding plug doors for 25T Passenger Trains. The door leaf is straight and can be divided into left and right. The driving mode is pneumatic and the control mode is electric control. The features are as follows:

The door lock is double locked, and an independent safety lock (isolation lock) is set, which is safe and reliable.

The door leaf adopts aluminum honeycomb composite structure, which has the advantages of light weight, high strength, good sealing performance, sound insulation and heat insulation.

The load-bearing driving mechanism of the door system has the advantages of simple structure, small movement resistance, convenient installation and high reliability.

The door system has the function of anti extrusion and automatic locking when the train speed is greater than 5km / h (5km / h signal is provided by the vehicle);

In addition, it can realize the centralized control of the whole train door system and communicate with the vehicle computer to realize the monitoring function.

The sliding plug door system is mainly composed of door panel, load-bearing driving mechanism, locking mechanism, isolation lock, internal and external operation, emergency unlocking device, anti freezing device, turnover pedal, air control unit, door electric control system and seals, fasteners and adjustment pads.
