Description

The utility model relates to the field of railway transport and can be used to connect the front and rear stops of the coupler with the end parts of the spinal beam of the frame of the railway carriage.

It is known to connect the front and rear stops of the automatic coupler with the cantilever part of the spinal beam of a railway carriage, in which the front and rear stops are made together, having internal reinforcing ribs, and are welded inside the channel of the spinal beam (RU 23848 U1, B61G 7/12, 07.20.2002).

The use of the combined stops is complicated in spinal beams made of a solid profile, since the width of the stops may not correspond to the width of the opening of the spinal beam in cases where the deviation of the position of the side walls of the spinal beam from the vertical exceeds standard values. The connection is made by welding the sides of the stops to the side walls of the spinal beam, which is associated with additional measures to strengthen the welded joint.

Also known are front and rear stops fixed in the opening of the spinal beam, made separately and consisting of stop squares having thrust pads and ribs on the inside (V. G. Golovanov, V. I. Ladygin. Automatic coupling. Device, operation and repair. State Railway Transport Publishing House, Moscow, 1956, pp. 49-50, Fig. 62, 63).

The use of separate stops allows you to mount them inside the spinal beams with different profile configurations, including a solid profile. However, when separate thrust angles are installed on the ridge beam, the thrust pad of one of the angles may shift relative to the other, which leads to an uneven load on the walls of the ridge beam and increased wear of the coupler parts.

The prototype is a device for connecting the stops of an automatic coupler to the spinal beam of a railway carriage, containing front and rear stops made with thrust platforms and with protruding elements on the side walls in the form of, respectively, longitudinal ribs and shaped tides, while the front stop is made combined with a shock socket , the back stop is made separate and consisting of two stop squares, and in the side walls of the spine beam, through fixing grooves are made to accommodate the protruding stop elements - g rizontalnye open ends with sill, slots for basing the longitudinal edges of the front stops, and shaped grooves, the window for the home curly tides backgauge (US 2007/0151941 A1, B61G 7/00, publ. 05.07.2007.

The prototype device contains a spinal beam, the design of which is weakened by the presence of open horizontal end grooves in the places of installation of the front stops and extensive curly grooves-windows in the places of installation of the rear stops.

The technical problem that cannot be solved by the known devices and solved by using the utility model is the reliable and durable fastening of the front and rear stops inside the spine beam, made both composite (from two zeta-shaped profiles, I-beams, etc.), and solid (from omega- profile, channel, etc.).

The technical result of the utility model is the versatility of the device with a strong connection of the front and rear stops with spinal beams made of profiles of various configurations, as well as simplifying the design and improving manufacturability.

The specified technical result is achieved in that the device for connecting the front and rear stops of the coupler with the spinal beam of the frame of the railway carriage contains front stops and rear stops, the contact angles of which are made with thrust pads and with external protruding elements on the side mating walls, and in the side walls of the spinal the beams are made through through the locking grooves to accommodate the protruding elements of the stops. The difference is that the front and rear stops are separate, the back stop is provided with an end plate, and the outer protruding elements of the stop angles of the stops are made in the form of stop ribs.

In special cases, the front and rear stops are rigidly fixed in the spinal beam by means of a welded joint.

In development of the main embodiment, the stop ribs of the stop angles can be made in the direction of the longitudinal axes of the stops, either perpendicular to the longitudinal axes of the stops, or in a combination of these directions, when on one of the stops the stop ribs are located along the longitudinal axis of the stop, and on the other, perpendicular to the longitudinal axis emphasis. In special cases of execution, reciprocal end-to-end fixing grooves in the spinal beam are made in the directions corresponding to the directions of the stop ribs of the front and rear stops.

The implementation of both front and rear stops separate, consisting of several parts, provides the versatility of the device, which consists in the ability to install stops in the spinal beams from the profile of various configurations.

The implementation of the outer protruding elements on the front and rear stops in the form of thrust ribs determines the execution in the walls of the spine beam of the reciprocal end-to-end fixing grooves with correspondingly small dimensions, which reduces the weakening of the strength and rigidity of the spinal beam in comparison with the prototype device, due to the smaller area of the through fixing grooves.

Simplification of the design of the device is achieved by reducing the number of stop elements. Each of the front and rear stops installed in one of the end parts of the spinal beam contains, respectively, two stop squares (front stop) and two stop squares and one end plate (back stop). The shock socket is not part of the front stop, which is separate.

Manufacturability at the stage of manufacture of the elements of the device is ensured by the implementation of the front stops separate, in contrast to the manufacture of their complex single casting with a shock socket. At the installation stage, the separate stop angles of the front and rear stops are freely and securely fixed in the opening of the spine beam, positioned by the stop ribs in the reciprocal through fixing grooves, after which the assembly is ready to weld.

A utility model is shown in the drawings: in FIG. 1 - front emphasis with shock socket (a) and rear emphasis (b), axonometric projection; in FIG. 2 - device for connecting the stops with the end part of the spinal beam, axonometric projection; in FIG. 3 - the same, bottom view; in FIG. 4 - the same, with the vertical arrangement of the ribs of the stops, axonometric projection; in FIG. 5 - the same, with a multidirectional arrangement of the ribs of the stops, axonometric projection.

The proposed device contains separate front 1 and rear 2 stops automatic coupler installed and welded in the openings of the end parts of the spinal beam 3.

The front stop 1 (Fig. 1 a) consists of stop angles 1.1, each of which has stop pads 1.2 at the ends and stop ribs 1.3 located on the outer sides of the side mating walls along the direction of the longitudinal axis of the front stop 1.

The back stop 2 (Fig. 1 b) consists of stop angles 2.1 and an end plate 2.2. Each of the contact angles 2.1 has thrust pads 2.3 at the ends and thrust ribs 2.4 on the outer sides located in the direction of the longitudinal axis of the back stop 2. The end plate 2.2 can be reinforced with stiffeners.

The spinal beam 3 (Fig. 2) can be made composite of two profiles welded together, or from a single solid profile. In the lateral walls of the spinal beam 3, in its end parts at the installation sites of the front 1 and rear 2 stops, reciprocal through fixing grooves 3.1 are made to accommodate the stop ribs 1.3 and 2.4.

The stop ribs 1.3 and 2.4, in addition to the function of reinforcing the stiffness of the stop squares 1.1 and 2.1, at the installation stage, perform the positioning function of the stops 1 and 2 in the side walls of the spine beam 3, and also contribute to an increase in the length of the welds. The stop ribs 1.3 and 2.4 can be located on the front 1 and rear 2 stops in a direction perpendicular to the longitudinal axes of the respective stops (Fig. 4), while the reciprocal through fixing grooves 3.1 are made in the direction perpendicular to the longitudinal axis of the spine 3. Stop ribs 1.3 and 2.4 can be located on one of the stops along its longitudinal axis, and on the other - perpendicular to its longitudinal axis (Fig. 5), while corresponding through through locking grooves 3.1 in the spine beam 3 are respectively made. The ribs 1.3 and 2.4 with respect to the outer surfaces of the side mating walls of the contact angles 1.1 and 2.1 should be equal to or greater than twice the thickness of the side walls of the spine 3 to ensure complete mutual engagement of these ribs and the through grooves 3.1, regardless of the deviation of the side walls of the spine 1 from the vertical provisions.

A utility model is implemented as follows.

Mount the front 1 and rear 2 stops inside the opening of the spinal beam 3 in each of its end parts, for which stop angles 1.1 and 2.1 are placed by stop ribs 1.3 and 2.4 in the corresponding through fixing grooves 3.1. Then they perform welding work by applying welds along the mating lines of the stop ribs and through fixing grooves. End plates 2.2 are welded to the ends of the stop angles 2.1 of the rear stops 2. At the ends of the spine beam 3, shock sockets 4 are installed, resting their halt with full-time surfaces 4.1 in the outer ends of the contact angles 1.3 of the front stops 1. Perform welding work by welding along the interface lines of the shock sockets 4 with the spine beam 3 and the front stops 1.
