Description

The utility model relates to railway transport, namely to subway cars that are equipped with devices for evacuating passengers in case of emergency.

A wagon is known that is equipped with an emergency exit device (see US patent No. 4615275 NKI 105-438, 1984), containing a hinged door located on the frontal part, on the inner surface of which there are steps that form a staircase.

This device does not provide the necessary ergonomics of the driver’s cab, as visibility from the driver’s workplace is limited due to the presence of a staircase door, and the cabin volume is reduced, which should be attributed to the disadvantages of the analogue.

A wagon with a device for emergency exit is known (see US patent No. 4216725 NKI 105-348, 1980), comprising a hinged modular door located in the middle of the frontal part of the wagon, on the inner surface of which there are a number of steps that form a ladder. In case of emergency, passengers are evacuated through the control cabin.

This device does not provide the necessary ergonomics of the driver’s cab, as the driver’s workplace has been shifted to the right side of the cab, visibility is limited due to the presence of a door-ladder, and the cab volume is reduced, which should be attributed to the disadvantages of the analogue.

Known devices for the evacuation of passengers from cars (World Railways magazine No. 7, 2001). The devices are manufactured by the transport department of Fine Products, Spain. The devices are designed to evacuate passengers from train cars that have stopped along the route due to a malfunction or for any other reason, and not having the ability to continue driving.

Devices are folding or sliding ramps and walkways. With their help, passengers can leave the car from the side or from the end (depending on the design of the device) to the platform, track or car of the auxiliary train arriving at the scene of the accident. Devices are used, in particular, in subways and on city railways. The device ramp, when the train is moving, is located under the floor of the car body and automatically extends if necessary, and the car door cannot be opened before it is pulled out. There is also a lock to prevent the car from moving before the ramp is returned to its original position, and an obstacle detector to extend the ramp. The device is powered by a 24 V DC on-board network. The ramp has dimensions 1 × 1 m, weight 56 kg and is designed for loads up to 325 kg.

The disadvantages of the analogue include the fact that such devices are operational only in regular emergency situations, the complexity of the design and the presence of an electric drive exclude the possibility of using the device when the power supply system is turned off.

The prototype of the utility model is taken as “Device for emergency exit from the subway car” (see patent RU No. 2123950 C1).

The car is equipped in the frontal part with an emergency exit device, comprising a door mounted on the frontal part of the car, a ladder and a mechanism for attaching the stairs to the frontal part of the car. The ladder is made of interconnected curved sections installed with the possibility of removal on the frontal part of the car one after the other, and the ladder fastening mechanism is made in the form of two rods, one of which is installed with the possibility of movement in the direction parallel to the car axis, and the other is fixed on the first with the ability to rotate in a vertical plane. In addition, one of the ends of each section has an eyelet, and the second end has a footrest mounted for rotation, while the first rod is placed in a guide rigidly attached to the lower part of the car body, and the second rod is installed with the possibility of interaction with the latch and bracket.

When an emergency occurs, open the door, lower to the rail-sleeper grid and bring the ladder into working position.

The disadvantages of the prototype include:

- a door installed on the front of the car significantly limits the driver’s workplace and the size of the control panel, as well as impairs visibility from the control cabin.

- the emergency exit device is not equipped with handrails, which significantly affects the safety of the evacuation of passengers.

- the need to descend on the rail-sleeper grid to bring the stairs into position.

Only the driver can operate the device and provide a through passage through the control cabin. If the driver does not have the physical ability to perform the necessary actions for any reason, evacuation through this device becomes impossible. It is also extremely difficult to timely activate the second emergency exit device located in the second end head carriage, which should be attributed to the disadvantages of the prototype.

The purpose of the utility model is to create a compact, easily folding device for evacuating passengers from the subway car to the railway track, which is located outside the control cabin and is driven directly from the passenger compartment, ensuring safe evacuation of train passengers through the side doors of the passenger compartment.

The essence of the utility model is that in the subway car, the device for evacuating passengers, in the transport position, is located in the niche of the end wall of the passenger compartment and consists of a platform and a folding sectional ladder, which are pivotally mounted on the end of the L-shaped rotary lever with the possibility of rotation Around him.

The other end of the L-shaped pivot arm is fixed to the car body using a bracket, with the possibility of rotation in a horizontal plane by 180 °.

The platform and the folding sectional ladder are equipped with handrails consisting of two parts, the upper and lower, which are made folding and can be rigidly fixed in the working position.

The aforementioned device is equipped with a locking mechanism in the transport position, which is made in the form of a screw clamp fixed in a niche of the end wall of the passenger compartment, and an additional latch is mounted on the bracket.

In case of emergency, passengers are evacuated from the subway car through the side doors of the passenger compartment.
