RU169110U1 - RAIL FOR THE RAILWAY HATCH COVER - Google Patents

Abstract

The utility model relates to the field of railway transport and can be used in freight gondola cars with unloading hatches. The emphasis contains an L-shaped support bracket (1) with a reinforcing rib (2) and is mounted on the transverse beam of the car (3). The technical result is a decrease in the metal consumption of the structure, which allows to reduce production costs.

Description

The utility model relates to railway transport and relates to devices for holding manhole covers of railway open wagons.

Known emphasis for the hatch of the gondola, containing a vertical welded and horizontal supporting flange, while the vertical welded flange is made of a Z-shaped profile (see SU 331950 A1, publ. 14.03.1972).

The disadvantage of this design is the use of a Z-shaped profile, which complicates the design and increases the complexity of manufacturing.

As the closest analogue, a die-welded stop for the hatch of a railway gondola car made in the form of two L-shaped brackets and stiffeners welded to them on a cross beam of a gondola car was adopted (see RU 96355 U1, published July 27, 2010). The technical problem inherent in this design is the presence of a large number of parts, which leads to an increase in the metal consumption of the product and the complexity of the manufacturing process of the structure.

The objective of the proposed utility model is to improve the design of the stop for the covers of the unloading hatches of a gondola car, aimed at increasing labor productivity and reducing energy consumption during assembly and procurement of parts for manhole covers.

The technical result of the utility model is to reduce the metal consumption of the structure, which allows to reduce production costs.

The technical result is achieved in that the emphasis for the hatch of the railway gondola is made in the form of a support bracket and stiffeners welded to it, the bracket is L-shaped, and the bracket is mounted on the transverse beam of the gondola car frame, and the surface of the stiffener joined to the support bracket the support bracket is made reciprocal, repeating the L-shaped form of the support bracket; the stiffener with its upper vertical end during installation can be connected to the transverse beam of the gondola car frame; stiffener may bevel; the upper part of the support bracket can be fixed on the transverse beam of the car by welding; the upper part of the support bracket can be fixed on the transverse beam of the car with rivets.

Comparative analysis with the prototype shows that the proposed emphasis for the hatch of a railway gondola differs from the prototype in that the support bracket is L-shaped, while the support bracket is mounted on the transverse beam of the gondola car frame, and the abutting surface of the stiffening rib of the support bracket is made in response form, repeating the L-shape of the support bracket; the rigidity rib during installation can be connected with its upper end to the transverse beam of the gondola car frame; a bevel can be made on the lower horizontal stiffener; the upper part of the support bracket can be fixed on the transverse beam of the car by welding; the upper part of the support bracket can be fixed on the transverse beam of the car with rivets. This difference from the prototype gives reason to argue that the proposed technical solution meets the patentability criterion of a utility model - "novelty."

The proposed utility model is presented on graphic materials, which depict:

in FIG. 1 - described emphasis, general view;

in FIG. 2 - described emphasis, side view.

The stop for the manhole cover (Fig. 1,2) contains an L-shaped support bracket and a reinforcing rib 2 welded to it. To further reduce the metal consumption, the rib 2 may have a bevel.

The technical result, which consists in reducing the metal consumption of the structure and reducing production costs, is achieved in the manufacture of the support bracket.

In the manufacture of an emphasis for the hatch of a railway gondola, a reinforcing rib 2 is welded to the L-shaped support bracket, the mating surface of which is made in the reciprocal form, repeating the L-shaped shape of the support bracket. After that, the resulting design is installed on the transverse beam 3 of the gondola car. When installing the stop on the transverse beam of the car, a rivet or welded joint can be used. When opening the hatch cover 4, the lid rests on the support bracket and remains in a fixed position until the car is unloaded.

Thus, the proposed design of the stop for the hatch of the railway gondola allows assembly using fewer assembly operations compared to the prototype and thereby make the structure in less time. For the manufacture of the proposed stops, basic equipment is sufficient (for example, a welding machine and a bench vise).
