Abstract

The invention discloses a method for opening a railway vehicle sliding plug door in an emergency state, which comprises a speed sensor, a collision sensor, a total stop switch and a manual switch, wherein the speed sensor provides a closed signal when the speed of a railway vehicle is less than 5 km/h; when the speed of the rail vehicle is more than 5km/h, the speed sensor provides a signal for normal running; when the rail vehicle is collided and is strong to a certain degree, the collision sensor sends out a closing signal; therefore, an emergency signal affecting public safety is sent out from the interior of the rail vehicle, a control person presses the main stop switch, and a closing signal is sent out by the main stop switch. According to the invention, when the rail vehicle has an emergency collision, the sliding plug door is correctly opened, so that the life safety of passengers is ensured.

Description

Method for opening railway vehicle sliding plug door in emergency state

Technical Field

The invention relates to the field of railway vehicle sliding plug doors, in particular to a method for opening a railway vehicle sliding plug door in an emergency state.

Background

With the continuous improvement of the running speed of the train, the manufacturing level of the vehicle is also rapidly developed. The sliding plug door is widely applied to railway passenger cars after being digested and absorbed in recent years, and the problem of maintenance of the sliding plug door is increasingly prominent in the long-term application process.

In practical application, the accident of crowding people caused by the failure of the anti-extrusion switch of the sliding plug door occurs sometimes, and the similar sliding plug door has the fault ratio that the bad opening and closing of the sliding plug door with the internal and external operation switches can cause some delays on the arrival, the going up and down and the field maintenance of the passenger car. The maintenance method of the sliding plug door in the prior art is rough, most of the sliding plug door is repaired after a fault occurs, and the hidden fault is difficult to detect in advance in the maintenance process. A train is a plurality of stopper sliding doors altogether, lets the vehicle section staff carefully overhaul one by one, also is difficult to realize. Especially in emergency, the sliding plug door can not be opened in time, so that the situation of the body of a passenger often occurs, and the life of the passenger is threatened certainly.

In view of the above-mentioned drawbacks, the inventors of the present invention have finally obtained the present invention through a long period of research and practice.

Disclosure of Invention

In order to solve the technical defects, the invention adopts the technical scheme that the method for opening the railway vehicle sliding plug door in the emergency state comprises a speed sensor, a collision sensor, a main stop switch and a manual switch; when the speed of the rail vehicle is less than 5km/h, the speed sensor provides a closed signal; when the speed of the rail vehicle is more than 5km/h, the speed sensor provides a signal for normal running; when the rail vehicle is collided and is strong to a certain degree, the collision sensor sends out a closing signal; therefore, an emergency signal affecting public safety is sent out from the interior of the rail vehicle, a control person presses the main stop switch, and a closing signal is sent out by the main stop switch.

Preferably, the manual switch has 2-level operation actions, the first-level unlocking action is outwards pulled, the second-level unlocking action is anti-misoperation unlocking action, the second-level unlocking action is clockwise twisting, and then the second-level unlocking action is anticlockwise twisting, so that the railway vehicle sliding plug door can be manually opened.

Preferably, the manual switch of the railway vehicle sliding plug door can be opened only when one or two conditions are met, one is that the speed sensor gives a closing signal when the vehicle speed is less than 5km/h, the collision sensor gives a closing signal when the collision sensor is subjected to strong collision, and the correct secondary unlocking action is met, or the speed sensor and the vehicle speed are less than 5km/h to give a closing signal, the main stop switch is pressed to give a closing signal, and the correct secondary unlocking action is met at the same time, so that the railway vehicle sliding plug door can be opened manually.

Compared with the prior art, the invention has the beneficial effects that: 1, the sliding plug door can be correctly opened when the rail vehicle has an emergency collision, so that the life safety of passengers is guaranteed. 2, the method of the invention is simple to operate and improves the actual work. 3, the method only needs to set the speed of the vehicle without disassembling any part, thereby improving the working efficiency of technicians. 4, the method can be operated by hands only by simply introducing driving personnel without long-time training, so that the long-time training is saved, the time is saved, and the personnel cost is saved.

Detailed Description

The above and further features and advantages of the present invention are described in more detail below.

Examples

The method for opening the railway vehicle sliding plug door in the emergency state comprises a speed sensor, a collision sensor, a main stop switch and a manual switch; when the speed of the rail vehicle is less than 5km/h, the speed sensor provides a closed signal; when the speed of the rail vehicle is more than 5km/h, the speed sensor provides a signal for normal running; when the rail vehicle is collided and is strong to a certain degree, the collision sensor sends out a closing signal; therefore, an emergency signal affecting public safety is sent out from the interior of the rail vehicle, a control person presses the main stop switch, and a closing signal is sent out by the main stop switch.

The manual switch has 2-level operation actions, the first-level unlocking action is outwards pulled, the second-level unlocking action is anti-misoperation unlocking action which is clockwise twisting, and then anticlockwise twisting is carried out, so that the railway vehicle sliding plug door can be manually opened.

The manual switch of the railway vehicle sliding plug door can be opened only when one or two conditions are met, one is that the speed sensor gives a closing signal when the vehicle speed is less than 5km/h, the collision sensor gives a closing signal when the collision sensor is subjected to strong collision, and the correct secondary unlocking action is met, or the speed sensor and the vehicle speed are less than 5km/h to give a closing signal, the total stop switch is pressed to give a closing signal, and the correct secondary unlocking action is met, so that the railway vehicle sliding plug door can be opened manually. According to the invention, when the rail vehicle has an emergency collision, the sliding plug door is correctly opened, so that the life safety of passengers is ensured; the operation is simple, and the actual work is improved; only the vehicle speed needs to be set, and any part does not need to be dismounted, so that the working efficiency of technicians is improved; and the driver can be operated by hands only by simply introducing the driver without long-time training, so that the long-time training is saved, the time is saved, and the personnel cost is saved.

The foregoing is merely a preferred embodiment of the invention, which is intended to be illustrative and not limiting. It will be understood by those skilled in the art that various changes, modifications and equivalents may be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
