Description

The invention relates to railway transport, and in particular to devices for evacuating passengers from the driver’s cab of a subway car in case of an emergency in the tunnel and on the ground sections of the subway.

A device is known for emergency exit of a rail rolling stock from a car, comprising a door mounted on the end of the car, consisting of an upper part and a lower part, which is a folding folding platform installed in the working position obliquely to exit the car, a mechanism for attaching to the door frame the wagon of the upper and lower parts in the transport position (patent WO 2013/026821, B61D 19/02, B61D 23/02, 02/28/2013).

This device does not provide fast evacuation of passengers, as located on the end of the car, and inconvenient during operation.

A device for emergency exit from the driver’s cab of the subway car, comprising a door for emergency exit, installed in the doorway on the front of the car, a ladder made in the form of steps and consisting of two parts installed with the possibility of rotation of the second part relative to the first part, the mechanism pull transformation of the ladder, elements of the device for fixing the ladder in the transport position (GB 2274092, IPC B61D 19/02, 07/13/1994).

The known device does not provide fast, reliable and safe evacuation of passengers in case of emergency.

The objective of the claimed invention is to ensure the safety of the carriage of passengers in subway cars in the event of an emergency.

The technical result when using the invention is to increase the reliability of the device and ensure quick, reliable and safe evacuation of passengers in case of emergency.

The specified technical result is achieved by the fact that in the device for emergency exit from the driver’s cab of the subway car, comprising a door for emergency exit installed in the doorway of the frontal part of the car, a ladder made in the form of steps and consisting of two parts installed with the possibility of turning the second part relative to the first part, the thrust of the door transformation mechanism, the elements of the device for fixing the door in the transport position, according to the invention, the door for emergency exit is equipped with a frame and installed with the possibility of turning up and down and fixing in the doorway, while the ladder is located on the inner surface of the door, with the first part of the ladder fixedly mounted on the door frame closer to its opening, and the door transformation mechanism is made in the form of a spring for smooth movement and a two-shouldered articulated lever mechanism, the first rod of which is made in the form of double parallel plates, and the second rod is made in the form of a rod with an elongated groove at the end from the side of the first rod.

In addition, the first part of the ladder consists of at least three steps having different widths, and the second part of the ladder is equipped with a panel that is installed in the working position inside the door frame to protect the window unit from destruction; the angle of the ladder in the working position is at least 24 ° relative to the level of the rail head; the elements of the device for fixing the door in the transport position are installed at a height equal to 3/4 of the door height; the second link of the transformation mechanism is fixed in the middle part of the door frame; the outer panel of the door is made of fiberglass, and the panel of the second part of the ladder is made of aluminum.

The invention is illustrated by drawings.

A device for emergency exit from the driver’s cab of a subway car (Fig. 1) contains a door 1 for emergency exit with a window unit 2, mounted with the possibility of up-down rotation and fixing in the doorway 3 of the frontal part of the car. The door 1 (figure 2) is equipped with a metal frame 4, on which the outer panel 5 is made of fiberglass.

Door 1 has two extreme positions - the transport position at which it is at the top, i.e. fixed in the doorway 3 cars; operating position at which it is at an angle to the level of the rail head, i.e. in an emergency.

On the inner surface of the door 1 is a ladder 6 in the form of steps. The ladder 6 consists of two parts (Fig. 2): the first part 7 and the second part, made in the form of a stepped block 8. The first part 7 of the ladder 6 is fixedly mounted on the metal frame 4 of the door 1 closer to its opening 3 and consists of at least three steps 9 of different widths: for example, for the safety of passengers at the exit, the upper step has a greater width than the rest of the steps. The folding step block 8 is mounted on the frame 4 with the possibility of rotation relative to the first part 7 of the ladder 6.

In the transport position (Fig. 3), the step block 8 is compactly placed inside the frame 4, while the steps of the step block 8 are located on the steps 9 of the first part 7 of the ladder 6. This arrangement of steps provides unobstructed view from the driver's cab.

The step block 8 is equipped with a panel 10 of aluminum, which in the transport position is located inside the driver's cab, and in the working position is located inside the frame 4 of the door 1 to protect the window block 2 from destruction.

In the operating position (figure 4), the ladder 6 is located, for example, at an angle of 26 ° to the upper level of the rail head, while the last step of the ladder 6 is located above the mentioned level at a distance of 210 mm, which ensures the safety of passengers when leaving the ladder 6.

For reliable fastening of the stepped block 8 in the transport and operating positions on the frame 4 (Fig. 2), there are latch locks 11, 12 (Fig. 5, 6) located at its opposite ends.

To bring the ladder 6 to the working or transport position, a transformation mechanism is provided (Fig. 2, 4) located on both sides of the door 1, made in the form of a spring 13 for smooth movement of the door 1 and a two-armed articulated lever mechanism, the first link 14 of which is made in the form of double parallel plates (Fig.7), and the second rod 15 is made in the form of a rod with an elongated groove 16 at the end from the side of the first rod 14, while the second rod 15 is fixed in the middle of the frame 4 of the door 1.

For fixing in the transport position of the door 1 in the doorway 3, the frame 4 contains on both sides the elements of the device for fixing the door, made in the form of plates 17, which are located at a height equal to 3/4 of the height of the door 1. In each plate 17 there is an alternating groove 18 cross-sections for engagement with the tongue 19 of the lock 20 located on the doorway 3 inside the driver's cab, and the smooth fit of the door 1 in the opening 3.

The operation of the device is as follows.

In an emergency, the locks 20 are opened from the inside of the driver’s cab, after which they push the door 1 with the ladder 6 out, giving it a slight acceleration. Under its own weight, the door 1 begins to fall to a certain angle of inclination of the ladder 6 to the upper level of the rail head. After moving the ladder 6 down, pull the lock-latch 11, release the stepped block 8 and turn (tilt) it until it is fully opened.

Then, in the open position, the step block 8 is fixed with a latch 12. The ladder 6 is securely fixed and ready for passengers to exit.

When moving the door 1 with the ladder 6 to the transport position, the step block 8 is first released from the latch 12, fold it with the first part 7 of the ladder 6 and fixed with the latch 11. Then, with a minimum effort, lift the door 1 into the doorway 3, close and locks 20 locks inside the driver's cab.

If necessary, the process is repeated.
