Description

The utility model relates to railway transport, in particular to railway tanks for the transport of various goods, equipped with stationary external stairs and folding steps.

Railway tanks are known that are equipped with boilers mounted on frames, boilers of which have folding steps (see "Freight cars of 1520 mm gauge railways. Reference album" 002I-2009 PKB CV JSC Russian Railways, 2010, p. 540 - taken as analog).

In these designs, to achieve the optimal technical and economic indicators of railway tanks and maintain the construction outline of the railway rolling stock dimensions, the folding steps of the outer staircase are used, which are mounted between the handrails and attached to the boiler. The steps are located in the middle part of the boiler and are fixed in loops, which provide rotation and installation of the steps in a horizontal (working) position. Each hinged step is equipped with hinges of a special configuration, which, when exposed to the efforts of staff, set it in a horizontal (working) position.

Also known is the design of the railway tank, taken as a prototype, including a boiler equipped with ladders mounted on bearing brackets mounted on the boiler, while intermediate connecting inserts are installed between the bearing brackets and stairs (RU No. 1777715 publ. 06.032018, B61D 5/00, B61D 23/00).

The disadvantages of the above designs is the location of the steps in the closest proximity to the boiler, which increases the time and laboriousness of servicing the railway tank, since the design of the folding step does not provide for self-return to the vertical (transport) position, which requires manual return to the vertical (transport) position. The step stands in a horizontal position (working) for the construction dimension of the railway tank, which is unsafe. Also, the monolithic design of the stairs limits its use in a number of dimensions of railway rolling stock with a boiler diameter of 3200 mm and above.

The consequence of the previously discussed disadvantages of the prototype is the limitation of the possibility of improving the technical and economic indicators of railway rolling stock due to the limitations of the standard size.

The task to which the utility model is directed is to provide increased safety for servicing the railway tank.

The task is achieved by the fact that in a railway tank, including a boiler with fittings, mounted on the frame, running gears, automatic couplings, brake equipment and an external staircase with platforms, consisting of three sections, the upper stationary section of which is fixed on the platforms and brackets of the boiler, according to the useful models, the middle folding section, at the level of the middle of the boiler combined with the ends of the levers of the shafts in the brackets welded through the plates to the boiler, is a rotational kinematic pair, each shaft of which The swarm is equipped with a twisted elastic element working for torsion, and under the levers of one of the shafts there are mounted stops that are welded to the boiler to fix the hinged section, the lower section of the ladder is bolted to the brackets of the boiler and frame with an internal slope of 0 ° to 10 ° relative to the tangent plane, which is parallel to the longitudinal plane of the boiler and does not go beyond the overall outline.

The utility model is illustrated by drawings, which do not cover and, moreover, do not limit the entire scope of the claims of this technical solution, but are only illustrative materials of a particular case of execution, where:

In FIG. 1- railway tank, main view; In FIG. 2 - railway tank, left view; In FIG. 3 - railway tank, view B in FIG. 2; In FIG. 4 - railway tank, view B in FIG. 3.

The inventive railway tank 1 (Fig. 1), including a boiler 2 (Fig. 1) with valves 3 (Fig. 1), mounted on a frame 4 (Fig. 1), chassis 5 (Fig. 1), automatic couplers 6 (Fig. . 1), brake equipment 7 (Fig. 1) and an external ladder 8 (Fig. 1) with platforms 9 (Fig. 1, Fig. 3), consisting of three sections, the upper stationary section 10 (Fig. 2) which is fixed on the platforms 9 (Fig. 1, Fig. 3) and brackets 11 (Fig. 3) of the boiler 2 (Fig. 1), characterized in that the middle hinged section 12 (Fig. 3), at the level of the middle of the boiler 2 (Fig. 1) combined with the ends with the levers of the shafts 13 (Fig. 4) in the brackets 14 (Fig. 4), welded through pads 15 (Fig. 4) to the boiler 2 (Fig. 1), is a rotational kinematic pair, each shaft 13 (Fig. 4) of which is equipped with a twisted elastic element 16 (Fig. 4), working on torsion and under the levers 13 (Fig. 4) of one of the shafts mounted stops 17 (Fig. 4), which are welded to the boiler 2 (Fig. 1) to fix the hinged section 12 (Fig. 3), the lower section of the ladder 18 (Fig. 2) is fixed with a bolt on the brackets of the boiler 19 (Fig. 3) and frame 4 (Fig. 1) with an internal slope of 0 ° to 10 ° relative to the tangent plane, which is parallel to the longitudinal plane of the boiler and does not go beyond the outline .

The working position of the movable section is provided by the effort of pressing the operator’s foot on one of the steps until it is fixed on the stops.

The presented design allows to reduce maintenance time and safer to operate the railway tank, which contains a rational design and manufacturing technology.
