Description

The utility model relates to the field of railway transport and can be used in tank cars with external stairs for lifting to service platforms.

Tanks are known, including a carrying frame, undercarriages, couplers, braking equipment, a boiler mounted on the frame with a manhole, external stairs and a transition platform, drain and tank fittings (see. Reference book “Freight cars of gauge railways 1520 mm, M .: Transport, 1989, p. 89-102).

A well-known railway tank is accepted for the closest analogue, including a frame mounted on the chassis, automatic couplers, brake equipment mounted on the frame of a boiler with a hatch, drain and tank fittings, external stairs, a service area near the hatch, safety arches (see RU 74877 U1, publ. 20.07.2008).

A technical problem that cannot be solved by the application of well-known technical solutions is the possibility of inconsistency of the external stairs of tanks with walkways (platforms), including stationary ones, which are equipped with loading and unloading platforms, car repair depots, rolling stock maintenance shops, etc., which leads to the impossibility of access to the boiler from walkways and requires additional shunting to position the filed for loading, unloading, or repairing the composition of tank cars.

The technical result achieved by using the utility model is to increase the safety of servicing tank wagons by providing unhindered access to the boiler service sites from the transitional bridges of infrastructure elements of enterprises serving the railway transport.

To achieve the specified technical result, the tank car contains a frame structure mounted on the running gear, couplers, brake equipment and a boiler mounted on the frame structure with a hatch, drain and bulk valves, a service area near the hatch, and external stairs for access to the service platform , is equipped with additional external stairs, mounted on the boiler on the side of the external stairs at the level of their upper steps.

In special cases of implementation, additional external stairs can be secured from each of the external stairs on the right side, either on the left side, or on both sides.

In special cases of implementation, additional external stairs can be made in the form of two steps, or three steps.

In special cases of implementation, the distance between the external stairs and the corresponding additional external stairs is 300-500 mm.

In special cases of implementation, external stairs can be fixed in the central part of the service platform, or with an offset from its center.

In special cases of implementation, a frame or half-frame can be used as the frame structure of the tank car.

The utility model is illustrated by drawings, which show:

in FIG. 1 - tank car with the location of the external stairs in the center of the service platform and additional external stairs, consisting of two steps and mounted to the right of the external stairs, the main view;

in FIG. 2 - the same, top view;

in FIG. 3 - tank car with the location of the external stairs in the center of the service platform and additional external stairs, consisting of two steps and mounted on both sides of the external stairs, the main view;

in FIG. 4 - tank car with the location of external stairs with offset from the center of the service platform and additional external stairs, consisting of three steps and mounted to the left of the external stairs, the main view;

in FIG. 5 is a section along line AA in FIG. one.

The tank car (Fig. 1) contains a frame 2 mounted on the chassis 1 with automatic couplers and braking equipment installed on it and a boiler 3 located on the frame 2. A hatch 4, a discharge and loading equipment, a tinning area 5 with fences are mounted on the boiler 3 arranged around the hatch 4, two external stairs 6 with handrails, fixed on both sides of the boiler 3, additional external stairs 7.

External stairs 6 can be located in the center of the service platform 5 (Fig. 1, 2, 3) or closer to one of the end faces of the service platform 5 (Fig. 4).

Additional external stairs 7 are fixed on the side of the boiler 3 at the level of the upper steps of the external stairs 6 at a distance of 300-600 mm. The location of the stairs 7 relative to the stairs 6 can be different - on the right side (Fig. 1, 2), on the left side (Fig. 3), on both sides (Fig. 4). Stairs 7, it is advisable to make of two (Fig. 1, 2, 3) or of three steps (Fig. 4). In FIG. 5 is a sectional view of an additional external staircase 7, consisting of two steps 7.1, welded onto the linings 7.2 of boiler 3.

The proposed utility model is as follows.

The train, formed from tank wagons, is fed to a loading / unloading platform equipped with stationary walkways. When exhibiting the composition, there is a possibility of a mismatch of the location of walkways and external stairs 6, which boilers 3 are equipped for ease of maintenance and safe access to the service platform 6 and equipment located on top of the boiler 3. Access to the external stairs 6 is also difficult in case of uneven distribution of unloading stands, loading and sampling of the transported product.

To access the external stairs 6 and service areas 5, tank cars are equipped with additional external stairs 7, due to which the number of passages from the overpass to each of the boilers for the composition of tank cars increases from one to two or three, depending on the number of installed stairs 7. The width of steps 7.1 is 500-550 mm. The optimal distance is a between the stairs 6 and 7, made in the range from 300 to 600 mm. Moreover, the location of the stairs 7 at a distance of less than 300 mm from the external stairs 6 reduces the likelihood of access to steps 6.1 with a significant displacement of walkways or standers relative to the position coaxial with the boiler 3. Exceeding the specified distance by more than 600 mm makes it difficult to move from steps 7.1 to steps of external stairs 6 along boiler 3.

The proposed design of the tank wagon allows you to seamlessly move from bridges, including stationary ones, to service platforms 5 sequentially through additional external stairs 7 and external stairs 6 in those cases when the transition bridges are exposed with a significant offset relative to the central transverse axis of the boiler 3 of the car tanks. When equipping tank cars with additional external stairs 7, safe maintenance of the tank car is provided regardless of the location of the transitional platforms of the flyover. In addition, it is not necessary to set up the walkway bridges coaxially to boiler 3 and, thereby, eliminates the need for additional shunting operations to position the composition of tank wagons submitted for work to the loading and unloading racks and other infrastructure elements serving the railway transport enterprises.
