Description

one

The invention relates to railway transport, in particular to structural elements of the bodies of railway vehicles, and relates to transitional areas of passenger cars.

The known transitional platform of a passenger car contains a transitional bridge, which includes a movable apron attached to the end wall of the car. the transitional area is its damageability in operation, caused by strikes against the transverse angle of the swivel apron and automatic coupling of the attached car. The indicated damages occur during coupling of cars that have a large difference in the levels of axles of couplings, as well as during mutual vertical movements of coupled couplings during the movement of the train. As a result of damage, there are cross beams, detachment from the beams of the movable apron and its fall onto the path that

creates a danger to passengers when moving from car to car. Repairing damaged parts requires repair.

In addition, a transitional platform with a movable apron mounted on a crossbeam is known, which does not exclude, in the process of coupling cars, damages to the transitional platforms with a rotary apron, with which passenger cars are in operation.

In accordance with the instruction manual for cars, the swiveling apron of these passenger cars must be in the raised position before coupling. However, this requirement by service personnel is not always fulfilled and leads

15 damage to the apron when coupling cars.

The purpose of the invention is to increase reliability and safety in operation.

The goal is achieved by the fact that

20 in the transitional area, the said transverse beam with an apron is mounted on the plates of the buffers with the possibility of longitudinal relative to the last movement, and connected with each of them by means of

spring-loaded leash, pivotally attached with the possibility of rotation around the horizontal axes respectively to the transverse beam and to the specified bracket and fixed stop, which is fixed to the bracket.

FIG. 1 shows a transitional plate, adka, top view; in fig. 2 - the same, front view; in fig. 3 - the same, side view; in fig. 4 is a view A of FIG. 3

The bridge plate contains a bridge consisting of a base plate 1 fixedly attached to the end wall of the car of the base plate, a movable apron 2 mounted on the transverse beam 3 supported by the supports 4 mounted with a backward inclination of the leads 4 on the brackets 5 of the buffer 6 of the buffer 7 The end part of the movable apron 2 is equipped with a sliding support and is freely supported on the support plate 1.

The transverse beam 3 at the ends attached to the axis of rotation 8 (axle). On axis x 8 of rotation, springs 9 are installed. The crossbeam with the help of the pivot axes 8 rests on the leads 4. The leads 4, with their end portions, are connected by horizontal rollers 10 with brackets 5, directed by their eyes to the end of the carriage. At the ends of the axes 8 of rotation n rollers 10 installed washers 11 and cotter pins 12.

The drivers 4 in the initial position are elastically clamped to the stops 13 of the brackets due to the application to the drivers of the force of the springs 9 hooked on the ribs 14 of the beam 3.

The device works as follows.

When coupling the cars of the plate, adjacent buffers touch each other and resiliently cross over with the crossbeam and with the movable apron to the end of the carriage. Base plates and movable aprons in coupled cars form a transitional bridge.

When a force is applied to the transverse beam 3 with a movable apron from the coupling body or the rotary apron of the attached car, the transverse beam 3 with the movable apron elastically moves up and in the longitudinal direction to the end wall of the car due to free rotation in the vertical planes of the leads 4. At the same time the plate the buffers can remain in the extended position, since the force of compression of the springs of the buffers is much higher than the forces of the springs of the torsion springs 9, thereby preventing plastic deformation in the cross beam with nym

an apron. The resetting of the transverse beam 3 with the movable apron 2 is made by the leads 4 and the torsion springs 9. The initial inclined-parallel position of the drivers 4 is fixed by the stops 13.

When the coupled carriage body acts on the transverse beam 3 — with application of force from below, transverse beam 3 due to the leads 4 deflects freely upwards and in the longitudinal direction, also preventing possible plastic deformations of the transition platform.

After the cars are uncoupled, buffer plates with a crossbeam installed on them with an apron under the action of springs installed in the buffers occupy an extended position.

The use of a transitional platform with a movable apron that is spring-loaded with respect to the plates will eliminate the breakdowns of the transitional sites and the need, therefore, to carry out repair work and, at the same time, ensure the safety of passengers moving from the car to the car. The economic annual effect is about 1000 rubles.
