Description

Technical field

The utility model relates to the field of railway transport, in particular to freight tank cars adapted for the transport of various liquids, including the transport of dangerous goods.

State of the art

From the prior art, a safety cap of a railway tank armature is known (author's certificate SU No. 1684178, B65D90/10, publ. 10/15/1991), including a casing pivotally mounted on an axis, fixed on a flange. The casing is made composite, and the axis is mounted vertically on the flange to ensure rotation of each part of the casing in a horizontal plane. The hood is opened by opening the flaps of the hood casing.

The technical problem inherent in this solution is the horizontal direction of the opening of the cap flaps relative to the vertical axis, which significantly complicates the maintenance of the tank car, since the open flaps make it difficult for personnel to move along the platforms for servicing the tank car and reduce the level of safety when servicing the tank car.

From the prior art there is known a safety cap of railroad tank fittings (patent RU No. 29918, B65D90/54, publ. 06/10/2003), containing a casing fixed on the hatch cover by means of a hinge assembly, the axes of which are located horizontally, and equipped with clamping locks. The cap is opened by tilting it.

The technical problems inherent in this solution are

the load acting on the hinge assembly of the safety cap, since when opening the safety cap remains in a vertical position due to the sickle-shaped plates installed on the hinge assembly;

there is not enough space for the location of the drain and fill fittings, since the shell of the safety cap in its upper part at the level of the location of the levers of the drain and fill fittings is made in the form of a truncated cone;

a high-lying edge of the base of the folded cap, which makes it difficult to use and maintain the tank car, since the high edge of the safety cap can make it difficult to service the car on the loading and unloading rack, in particular, when connecting the ganders of the loading and unloading fittings or performing other types of automatic maintenance .

A tank car is known from the prior art (patent RU No. 175951, B61D5/00, B65D 90/10, B65D 88/06, publ. in the form of a frame or semi-frame, on which the boiler is fixed, containing a shell, bottoms and a safety cap with a shell and a cover, according to this utility model, the safety cap shell in its upper part is made with a bevel at an angle "α" in the range from 20 to 60 ° from the horizontal, while the shell of the safety cap is closed from above by a lid. The protective cap can be made with a bevel, in which the lower edge of the bevel is located at a height "h" from the base of the protective cap, maintained in the range from 120 to 250 mm. The cover of the safety cap can be made with a bend. The cover of the safety cap can be made of two connected elements, one of which covers the main part of the safety cap, and the second element closes the bevel.

The disadvantage of the known solution is the high metal consumption and laboriousness of manufacturing the protective cap of the hatch of the tank car due to the complex geometry of the shell.

Utility Model Disclosure

The technical task of the utility model is to reduce the metal consumption of the safety cap of the tank car while providing the necessary useful volume inside the cap to accommodate the drain and fill valves in comparison with existing models of tank cars while maintaining the safety of cargo transportation by simplifying the geometry of the shell and the cover of the hatch safety cap tank wagon.

The technical result is achieved by the fact that, with respect to the well-known technical solution containing a frame installed on the undercarriage, on which the boiler is fixed with a drain-fill valve closed by a safety cap with a shell and a lid, the proposed utility model differs in that the shell 6 of the safety cap 5 of the hatch is made with a smooth bevel at an angle "α" from the horizontal in the range from 1° to 20°, and the lower edge of the bevel is located at a height "b" from the base of the safety cap 5 in the range from 0.1s to 0.96s, where c is the distance from the base of the protective cap to the upper border of the flat cover of the protective cap of the hatch.

The utility model is supplemented by particular features that contribute to the achievement of the technical result. Thus, the shell 6 is cylindrical.

Implementation of the utility model

The essence of the utility model is illustrated by the drawings, where in Fig. 1 shows a general view of the tank car, Fig. 2 – general view of the hatch cover of the tank car.

The railway tank car (Fig. 1) contains a frame 1, a boiler with a drain-fill valve 2, closed with a hatch safety cap 5, a running gear 3, automatic coupler and brake equipment 4.

The protective cap of the hatch 5 of the tank car (Fig. 2) contains a shell 6 of a cylindrical shape, having a smooth bevel along the longitudinal axis (at an angle from the horizontal) of the tank car, and a flat cover 7 and a hinge 8, while the bevel of the shell 6 of the safety cap 5 is made at an angle "α" from the horizontal in the range from 1° to 20°, and the lower edge of the bevel is located at a height "b" from the base of the safety cap 5 of the hatch in the range from 0.1s to 0.96s, where "c" is the distance from the base of the safety cap 5 to the upper border of the flat cover 7 of the safety cap 5 of the hatch.

The protective cap 5 of the hatch of the tank car is fixed on the hinge 8 for the possibility of rotation in the vertical plane by means of the hinge 8.

Compared with the known technical solutions, the proposed technical solution provides a reduction in the metal consumption of the safety cap of the hatch of the tank car while providing the necessary useful volume inside the cap for the possibility of placing drain-filling valves by simplifying the geometry of the safety cap of the safety cap of the hatch of the tank car while maintaining the safety of cargo transportation.

Claims (2)

A tank car containing a frame installed on the undercarriage, on which a boiler is fixed with a drain-fill valve closed by a safety cap with a shell and a lid, characterized in that the shell of the hatch safety cap is made with a smooth bevel at an angle α from the horizontal in the range from 1° to 20°, and the lower edge of the bevel is located at a height b from the base of the safety cap in the range from 0.1c to 0.96c, where c is the distance from the base of the safety cap to the upper border of the flat cover of the hatch safety cap. 2. The tank car according to claim 1, characterized in that the shell is made of a cylindrical shape.
