Description

The utility model relates to the field of railway transport and can be used in freight cars to connect the end and side walls of the body along their upper harnesses.

The knot for connecting the upper strappings of the side and end walls of the body of a railway carriage (patent No. 104126, published May 10, 2011, IPC B61D 17/00) containing the upper and lower plates rigidly fixed to the end of one of the upper strappings and protruding beyond it is known from the prior art. end, and the upper plate is fixed on the upper surface of the upper trim of the side wall, and the lower plate is fixed on the lower surface of the upper trim of the side wall. A hole is made in the protruding part of each lining, and the end of the upper strapping of the end wall is located between the protruding parts, in which a through hole is made through which the rod passes, simultaneously passing through the holes in the lining.

The disadvantages of this technical solution are:

- the use of the rod, which causes the mobility of the connection of the upper strands and leads to increased wear of parts and the formation of backlash, which increases the risk of destruction of the design of the connection node as a whole;

- the protrusion of the rod over the upper surface of the upper lining during unloading can lead to a skew of the body relative to the paws of the vibrator on the tipper, which leads to the occurrence of cracks in the welds and parts;

- lack of tightness in the connection node of the harness, entailing the spillage of the cargo, as well as the ingress and accumulation of moisture in the internal cavity of the node, which leads to corrosion of the parts of the node.

The prior art known is selected for the prototype node connection of the upper strapping of the body of the gondola (patent No. 157727, published 10.12.2015, IPC B61D 17/00), containing a pad rigidly connected to the upper surfaces of the upper strapping having closed cross sections. The overlay is made in the form of a plate bent to form two parts located at an angle relative to each other, while one part is formed by two sections-petals for rigid connection with the upper surfaces of the upper strapping, respectively the end and side walls, and the other part is formed by a wedge-shaped section for mating and rigid connection of its lateral edges with the side surfaces of the upper harnesses inside the gondola car body.

The disadvantages of this technical solution are:

- the complexity of manufacturing part of the lining with sections of the petals, the metal consumption for their implementation and the small area of overlap of the junction of the upper strapping;

- the difficulty in installing the lining on the upper surface of the upper strapping when the difference in height of the strapping from the floor level;

- a large number, therefore, a large length of the welds that create stress concentrators;

- lack of tightness in the connection node of the harness, entailing the spillage of the cargo, as well as the ingress and accumulation of moisture in the cavity of the lining itself, in its bent part and in the internal cavity of the node, which leads to corrosion of the parts of the node.

The technical problem, the solution of which is ensured by the implementation of the proposed technical solution, is the low strength characteristics of the connection node of the upper harnesses of the end and side walls of the body of a railway carriage.

The technical result of the claimed utility model is to increase the strength, reliability and tightness of the connection of the upper harnesses of the end and side walls of the body of a railway carriage.

The specified technical result is achieved by the fact that in the connection node of the upper harnesses of the side and end walls of the gondola car body, comprising the upper harnesses and the sheathing sheets of the side and end walls of the gondola car body and a reinforcing element fixed to the inner corner of the connection unit, according to the present utility model, the reinforcing element is rigidly connected with the lateral surfaces of the upper harnesses and is made in the form of a plate bent in two places, the upper and lower parts of which are located at an angle to the middle part and have a triangular the shape corresponding to the shape of the inner corner of the connection node, and the middle part is made of a quadrangular shape.

The implementation of the reinforcing element provides increased strength and reliability of the connection of the upper strapping due to the rigid connection of the reinforcing element with the side surfaces of the upper strapping of the side and end walls of the gondola car body, thereby forming two stiffening ribs of the connection node of the upper and lower parts of the reinforcing element. The location of the upper and lower parts of the reinforcing element at an angle to its middle part ensures the flow of water from the inner corner of the joint, as well as the prevention of corrosion in this area, at welds, as well as other internal “closed” places (cavities) of the joint, which increases tightness of the connection.

A possible development option for the main technical solution is that the lower part of the reinforcing element is made at right angles to the middle part of the reinforcing element.

A possible development option for the main technical solution is that the upper and lower parts of the reinforcing element are made at right angles to the middle part of the reinforcing element.

The location of the upper part or the upper and lower parts of the reinforcing element at right angles to the middle part provides increased strength and reliability of the connection node due to the best load transfer with bursting forces inside the gondola car body in a horizontal plane in the upper and lower faces of the strands of the end and side walls of the body and the corresponding faces of the reinforcing element.

A variant of the development of the main technical solution is possible, consisting in the fact that under the lower face of the reinforcing element there is an additional corner plate rigidly connected to it, and also rigidly connected to the sheathing sheets of the end and side walls inside the car body, which ensures increased strength and reliability of the connection node due to the formation of an additional stiffener and a reinforcing element of the joint. In addition, an additional angular plate forms an inclined surface, which provides increased tightness due to overlapping of “blind” zones in the corners of the connection of the upper harnesses, forming an inclined surface along which the load is poured onto the car dumper.

A development option for the main technical solution is possible, consisting in the fact that the additional corner plate is also rigidly connected to the upper strapping of the side and end walls of the body, which provides increased strength of the entire structure as a whole by increasing the area of the load distribution transmitted from the upper strapping to the reinforcing element.

A development option for the main technical solution is possible, consisting in the fact that the upper and lower parts of the reinforcing element are made with a slice at the tops.

A possible development of the main technical solution is that the additional corner plate is made with a slice at the tops.

Performing a cut on the tops of the upper and lower plates, as well as on an additional corner plate, increases the strength and tightness of the joint by placing welds in the inner corner of the joint, namely at the junction of the reinforcing element and the side surfaces of the upper strands of the side and end walls, and also sheets of the skin of the side and end walls of the body of the railway carriage.

The essence of the claimed utility model is illustrated by drawings: FIG. 1 - corner of a freight car (top view), FIG. 2 is a view in the direction of arrow A shown in FIG. 1, FIG. 3 is an embodiment of a connection assembly (view in the direction of arrow A shown in FIG. 1), FIG. 4 is an embodiment of a joint assembly (cross-sectional view).

The connection unit of the upper strands of the side and end walls of the body of the railway car shown in FIG. 1-4, contains the upper strapping of the side and end walls 1 and 2, respectively, and a reinforcing element 3. The reinforcing element 3 is made in the form of a plate bent in two places, the upper 4 and lower 5 parts of which are located at an angle to the middle part 6. In the presented embodiment the upper 4 and lower 5 parts of the reinforcing element 3 are located at right angles to the middle part 6.

The upper 4 and lower 5 parts of the reinforcing element 3 are made of a triangular shape corresponding to the shape of the inner corner 7 of the connection node of the upper strands 1 and 2. The reinforcing element 3 is welded to the side surfaces of the upper strapping of the side 1 and end 2 of the body walls along the edges 8 and 9. Also for the placement of welds in the inner corner 7 of the connection node, the upper 4 and lower 5 parts are made with a slice 10 at the apex of the corner. The middle part 6 (shown in Fig. 2) is made of a quadrangular shape.

In FIG. 3 and 4, an embodiment of the main technical solution is presented, where an additional angular plate 11 is installed under the reinforcing element 3, forming an inclined surface 12 that covers the “blind” zones at the junction angles of the upper strapping 1 and 2 of the reinforcing element 3 and the side sheathing sheets 13 and end 14 body walls of a railway carriage. An additional corner plate 11 is rigidly connected to the reinforcing element 3 on the bend 15 and to the sheathing sheets 13 and 14 (in the presented embodiment, welded along the edges). In addition, the additional corner plate 11 can be rigidly connected to the side surfaces of the upper strands 1 and 2 (in the presented embodiment, welded along the edges). To place welds in the inner corner of the joint, an additional corner plate is made with a slice 16 at the top of the corner.

The utility model works as follows:

The reinforcing element 3 is made of sheet metal. Upper harnesses 4 and 5 (in the presented embodiment) have the form of a closed profile of square or rectangular section. After assembly of the car body, the assembly of the joint is carried out. Reinforcing elements 3 are fixed by welding in each of the upper nodes of the body, formed by the connection of the upper strapping of the side 4 and end 5 of the walls of the body. Welds pass along the edges of the joint 8 and 9 of the reinforcing element 3 and the upper strapping 4 and 5. An additional corner plate 11 is welded edges to the sheathing sheets of the side 13 and end 14 of the body walls. Also, if necessary, an additional corner plate 11 is welded to the side surfaces of the upper strands 4 and 5 to provide greater strength of the joint.

In the process of unloading the car on the car dumper, due to the inclined surface 12 of the additional corner plate 11, a more complete precipitation of the cargo from the corners of the car body takes place.

Thus, the claimed utility model with its entire set of essential features allows to increase the strength, reliability and tightness of the connection of the upper harnesses of the end and side walls of the body of a railway carriage.
