Method for rescuing passengers and crew of a high-speed train in case of a possibility of its collision with another train or obstacle

FIELD: transport.

SUBSTANCE: invention relates to railway transport. It relates to a way of rescuing passengers and the crew of a high-speed railway train at a risk of a possible collision with another train or an obstacle and involves the following: when there is a threat of a collision, the control units send a command to roll out the capsules of all cars and driver’s cabs. Then, pull-out panels with passengers sitting on their seats are rolled out of the trains, and the driver’s cab with the crew members is rolled out as well. After the evacuation of passengers from withdrawable capsules, and the evacuation of the crew members from the driver's cab, the axle axles are extracted from all the tongs and the heads of the right and left rails are release from the former. Then they are inserted into the tongs, while the hinged panels are installed in their places in the driver's cab, after the arrival of trains without their withdrawable elements, draw-out elements are tightened by their winches.

EFFECT: it is possible to increase the reliability of rescuing passengers in case of a possible train accident.

FIELD: construction.

SUBSTANCE: device (1) comprises a frame moving on a rail (7) on two wheels (4, 5), arranged in a line along the rail (7). The device may be equipped with an electric arc welding facility (9). When wheels (4, 5) are on the rail (7), then the centre (22) of gravity of the device is on the vertical line of the rail (7). Each of two wheels (4, 5) is equipped with two flanges in the form of cheeks of circular form. One of cheeks is movable for fixation of the device (1) in specific position on the rail (7), pressing the rail head (7) as in a vise between wheel cheeks (4, 5). If the device has to be moved, one cheek is loosened, restoring the wheel mobility.

EFFECT: possibility to fix wheels relative to a rail for provision of precision of operations for maintenance of rails such as electric arc welding, and possibility to vary the distance between cheeks make it possible to use a device on rails of different width.

Method of braking // 2451615

FIELD: transport.

SUBSTANCE: invention relates to railway transport, particularly, to railway transport braking equipment. Proposed method consists in that, after sending instruction for train last car braking from engineman cabin to last car control unit, rail brake shoes are downed on rails between center of gravity of the car and last mounted axle. Fail-safe linearly increasing deceleration force for last car is generated and transmitted via last car coupler to ahead cars of the train. Braking force transmitted from last car coupler transducer is operated at threshold braking force transmitted to ahead cars. Simultaneously, last car coupler transducer sends instruction via pulsed force blocking link to actuators of last but one car for it to down shoes on rail heads. Further, above operations are repeated for third, fourth, fifth and next cars from train tail unless braking of train locomotive. After elimination of braking cause, instruction is generated to up shoes in preset position. Now, train goes on running along preset route.

EFFECT: higher safety.

FIELD: transport.

SUBSTANCE: invention relates to railway transport, particularly, to rolling stock braking equipment. Proposed method consists in downing brake shoes on rails. After automatic registration of the fact that train stopping distance exceeds length of track to sudden obstacle, alarm is switched on in cars to warn passengers about emergent evacuation. Grippers are downed on rails behind last car of high-speed train to grip rail heads. Then, tail car top rear face fragment is detached from the train. Pan with passenger seats is displaced relative to tail car when gripper spring ties get tensioned. Then, similarly pan with seats of last but one car is displaced relative to last and last but one cars. Similar jobs are performed for all other train cars. Pan dynamic inertial forces are killed by elastic forces of spring ties and pan friction against track.

EFFECT: higher safety.

Locking assembly elements are complemented by lock bolt-plug with two recesses for seal collar and its tetrahedral lock nut. In standard operation of said brake the depth of screwing-in of the lock bolt-nut cover separating the screw piston working chamber from atmosphere is made to its first threaded end of said recess and locked by said nut. Simultaneously, said cover is sealed by a standard seal collar of used plug. To lock automatic hand brake said lock bolt-plug is screwed in said cover to its second recess from its threaded end. This allows extra screwing of lock bolt-plug in the screw inner thread end. Besides, it is locked by said nut and said cover is sealed by standard collar rearranged from the first recess of standard collar.
