Description

The utility model relates to the field of railway transport, in particular to clearance-free coupling devices of rolling stock, and is intended for automatic coupling of wagons.

Known rigid coupling device of railway transport, which contains two coupling heads with locking devices in the form of spring-loaded bolts with the possibility of interaction with the guide element, each of which is equipped with a trip mechanism. Each trip mechanism contains an energy accumulator connected by an actuator to the bolt of the hitch and equipped with a release device (according to patent RU 2254253, B61G 3/00, B61G 3/08, B61G 3/28, publ. 20.06.05).

The disadvantage of this solution is the design complexity, due to the presence of two locking devices on each coupling head.

As a prototype, a rigid railway coupling with a signaling device of locks was taken, containing two coupling heads, on one of which two locking devices were fixedly mounted. Each of the locking devices contains a housing and a movable spring-loaded deadbolt with a shank. Mutually connected levers are located on the body and shank. In this case, one lever is fixedly mounted on the shank, and the second is pivotally mounted on the housing of the locking device and is equipped with a signal flag (according to patent RU 156957, B61G 7/00, B61G 3/14, publ. 20.11.15).

The disadvantage of this solution is the lack of reliability of the coupling, due to the fact that the bolt and shank are made in the form of separate interconnected parts, and the trip mechanism is attached using brackets that are mounted on two bolts on opposite sides of the head.

The technical result, which the proposed utility model is aimed at, is to increase the reliability of the backlash-free coupling device, as well as to increase the manufacturability due to the design of the bolt and the method of attachment of the trip mechanism.

The specified technical result is achieved by the fact that the clearance-free coupling device contains two coupling heads with locking and trigger devices, locking devices are fixedly mounted on both sides on one of the heads, each of which is equipped with a movable spring-loaded bolt with a shank and a plate, and on the other head with both sides on two brackets mounted movable stops and is characterized in that each bolt with a shank and a plate is made as a single part, and each bracket is attached to the head with four threaded connections.

In addition, the thickness of the bolt plate must be at least 15 mm.

In addition, the threaded connection can be made in the form of bolts.

The proposed utility model is illustrated by the following drawings:

FIG. 1 - clearance-free coupling device, a longitudinal section;

FIG. 2 - a head with movable stops on the brackets, a longitudinal section;

FIG. 3 - movable stops on the brackets, front view;

FIG. 4 - movable stops on the brackets, side view;

FIG. 5 - deadbolt with shank and plate.

The clearance-free coupling device (Fig. 1) contains two coupling heads of the same type 1, 2 and a guiding element 3. Locking devices are installed on the head 1 on both sides, each of which consists of a housing 4, a bolt 5 with a shank 6 and a plate 7. The bolt 5 preloaded by springs 8. Housing 4 is attached to the head 1 with four bolts. On the guide element 3 made coupling holes 9.

The trigger device consists of split wedges 10, preloaded by springs 11 and mounted on both sides of head 1 in grooves 12 of shanks 6, and movable stops 13 mounted on two brackets 14 on both sides of head 2. Brackets 14 are fastened with four bolts 15 each, respectively, in each bracket 14 there are four mounting holes 16. The movable stops 13 are connected by a rod 17.

Application.

When the carriages are engaged, the guide member 3 mounted on the coupling head 2 is inserted into the cavity of the coupling head 1 by its conical part. When the positions of the bolts 5 coincide with their coupling holes 9 in the guide element 3 under the action of the springs 8, the bolts 5 move and enter the holes 9, engaging. At the same time, the movable stops 13 move the split wedges 10, compressing the springs 11.

To disengage the wagons, the wagon coupler manually releases the movable stops 13 from interacting with the spring-loaded disengaging wedges 10, as a result of which the latter, interacting with the inclined surface of the bolts 5, remove them from the coupling holes 9 of the guide element 3. The hitch is ready for disengagement. Further, in the process of breeding cars, the guide member 3 is withdrawn from the cavity of the coupling head 1. The cars are disengaged.

The execution of the bolt 5 with the shank 6 and the plate 7 in the form of a single part can significantly increase the strength of the part. In the case of separate execution and subsequent connection by means of threading and welding, the sufficient strength of the weld is not ensured due to the difficult to weld high alloy steels from which the bolt and shank are made. Also, manufacturability is improved, since operations on joining parts and threading are excluded.

The coupling heads 1 and 2 have the same design. Four threaded holes are made on the sides of the coupling head. On one head, all of these openings are used to attach the locking devices, and on the other, all of these openings are used to attach the brackets. Whereas in the analogues and prototype, each bracket is mounted on two bolts, and the other two holes are simply protected from contamination by bolts or plugs. Installing the bracket on four bolts increases the strength of the fastening and increases the reliability of the coupling device.

Also, to increase the reliability of the coupling device, the thickness of the plate 7 should be at least 15 mm.

 Thus, the solutions used in the utility model ensure the achievement of a technical result.
