Description

FIELD OF TECHNOLOGY

This utility model relates to transport, in particular to railway tank cars.

BACKGROUND

From Russian patent No. 57729, IPC B65D 88/74, published October 27, 2006, a tank car is known for transporting solidifying and crystallizing products. The wagon contains a boiler mounted on the frame, made of a cylindrical shell and two closed end bottoms. The boiler is equipped with a manhole and external stairs on the body. The cylindrical shell of the boiler is also equipped with a shadow protection screen, which is located on both sides of the manhole and attached to it.

However, in the case of a mismatch in the handrail for access by personnel with the gangway on the overpass when positioning the car under the overpass, this design of the tank car does not provide a sufficient degree of security when the staff moves from the flyover to the maintenance platform in the central part of the tank car.

Thus, the technical problem is the lack of technical means in the design of the tank car to ensure the safe passage of personnel from the gangway of the flyover to the service platform for the manhole of the tank car.

DISCLOSURE OF THE ESSENCE OF A USEFUL MODEL

The technical result of the utility model is to increase the safety of personnel transfer from the gangway of the flyover to the service platform of the manhole of the tank car.

This technical problem is solved by creating a tank car containing a frame and a boiler mounted on the frame, in the upper part of which there is a manhole and external stairs located on both sides of the boiler, as well as a shadow protection screen located on both sides of the manhole. A distinctive feature is that the boiler is equipped with steps located in the cutouts made in the shadow protection screen. Steps can be installed on both sides of the external stairs on both sides of the boiler.

Steps can be installed on one side of the external stairs on both sides of the boiler.

Steps can be installed on both sides of the external stairs on one side of the boiler.

Each cutout can have a length of 500 mm to 1050 mm and a width of 150 mm to 550 mm.

Each cutout can be made at a distance of 350 mm to 1050 mm from the central transverse plane of the boiler along its longitudinal direction and at a distance of 850 mm to 1450 mm from the upper generatrix of the shadow protection screen in an arc downward.

BRIEF DESCRIPTION OF THE DRAWINGS

The essence of the utility model is explained in more detail on non-restrictive examples of its implementation with reference to the accompanying drawings, in which:

FIG. 1 depicts a general view of a tank car;

FIG. 2 is a top view of a tank car;

FIG. 3 shows a local view of a notch for a step.

IMPLEMENTATION OF A USEFUL MODEL

Next, with reference to the accompanying figures, an example of the implementation of the utility model is described in detail. Tank car, as shown in FIG. 1 and 2, contains a boiler 1 mounted on a frame 2. The boiler 1 has a cylindrical shell 3 and two closed end bottoms 4. In the upper part of the boiler 1 there is a manhole 5 and external stairs 6 located on both sides of the boiler. A removable shadow protection shield 7 is also installed on the boiler 1, which is located and fixed on both sides of the manhole. 5. A platform 8 is located around the hatch, from which stairs 6 pass on both sides.

In the screen 7, in the immediate vicinity of the outer staircase 6, cut-outs 9 are made in which steps 10 are mounted. The steps 10 can be mounted directly to the boiler 1, in particular to the shell 3. Each cut-out can have a length l ranging from 500 to 1050 mm, and a width b ranging from 150 to 550 mm. Cutouts 9 are placed at a height H, ranging from 850 to 1450 mm, in an arc from the upper generatrix of each screen 7, and a distance L, ranging from 350 to 1050 mm from the central vertical axis of the tank car.

Moreover, if the dimensions of the length l and width b of the cutouts, as well as the dimensions of the height H and the distance L of the location of the cuts are less than the indicated ranges, then the possibility of an unsafe transition arises, since it becomes impossible to set a step wide enough for a safe transition with a height that allows you to put your foot on. It should also be noted that any exit of the cutout sizes and their location beyond the indicated ranges will lead to the displacement of the steps relative to the gangway of the flyover, which also affects the decrease in safety for maintenance personnel. The choice of parameter values that exceed the specified maximum values of the ranges will also lead to an increase in the level of stresses, and, consequently, to a decrease in the reliability of the design of the shadow protection screen, which will no longer satisfy the strength requirements.

In the present embodiment of the utility model shown in FIG. 1-2 the tank car contains four cut-outs 9 in the shadow protection screen 7 with steps 10 located in them. However, other implementation options are possible, according to which cut-outs 9 are made in the screen 7 and, accordingly, steps 10 are located on only one side of the tank car , but on both sides of the outer staircase 6, or only on one side of the outer staircase 6, but on both sides of the tank car, or on one side of the outer staircase 6, but located on both sides of the tank car on its diagonal.

The cut-outs 9 in the shadow protection screen 7 provide the placement of steps 10 as a support for the maintenance personnel in a situation, for example, when when positioning the tank car under the overpass, the external stairs 6 are not connected to the ramp ladder and displaced relative to it. In this case, a step 10 is used, which is located at the level of the gangway and provides the employee with the opportunity to safely move to the platform 8. Thus, the proposed design of the tank car provides increased personnel safety when moving from the gangway of the flyover to the service platform of the manhole 5 of the tank car.

This utility model is not limited to the specific options disclosed in the description for illustrative purposes, and covers all possible modifications and alternatives that fall within the scope of this utility model defined by the utility model formula.
