Brake assembly for chassis of telpher railway


B61H9/02 - for aerial, e.g. rope, railways

FIELD: transportation.

SUBSTANCE: brake assembly comprises brake pads, rocking levers, a connecting means, a socket for the connecting means in frame of the brake assembly. The rocking levers affect the brake pads with their upper ends, and are in active contact with the brake spring with their lower ends. The connecting means with the possibility of rotating two rocking levers is made in the form of a cross bar which runs between the two rocking levers, or in the form of connecting brackets of two rocking levers which are connected with each other with the possibility of rotation in one common swivel pad. The rotatable connecting means is displaceable in the socket for connecting means across the running direction of the chassis.

EFFECT: compactness of the brake, possibility of compensating the tolerances between parts of the brake pair.

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.

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.
