Description

The utility model relates to ladders placed inside covered freight cars (car bodies), for example, hopper cars, to provide access for maintenance personnel inside the body or tank car during internal inspection and repair.

From the patent of the Russian Federation No. 188282 for a useful model, a removable body is known, containing a frame, end and side walls, a roof, while a ladder is installed on the end wall, including two guides and crossbars located between the guides, the guide stairs in the upper part are bent onto the roof and fixed on the roof surface, while the guide stairs in the upper part have two bends with the formation of straight sections located parallel to the roof surface, and end sections located perpendicular to the roof surface and fixed on the roof.

From the patent of the Russian Federation No. 79853 for a utility model, a freight car ladder is known, consisting of two parts placed on the outer and inner surfaces of the walls of the car, each of which contains two racks interconnected by steps, thrust elements of the upper ends of the racks for fixing the working position of the ladder, at the same time, both parts are connected to each other at the level of the upper border of the car by a step, in addition, on the part of the ladder located outside the car, two handrails are fixed, made in the form of a cone-shaped bracket, one end of which is attached to the rack, and the other to the upper step of the ladder. The thrust elements of the upper ends of the racks for fixing the working position of the ladder are made in the form of hooks welded to the upper ends of the racks.

The disadvantage of these well-known ladders is their unreliability, due to the possibility of damage to the places of rigid connection of the ladders with the body due to dynamic loads arising during the movement of the car.

The ladder according to patent No. 79853 is chosen as the closest analogue.

The technical problem solved by the utility model is the creation of a reliable design of the internal stairs of a covered freight car.

The technical result achieved by the utility model is to increase the reliability of fastening the internal stairs of a covered freight car, to reduce the likelihood of damage to the stairs and their fastening points when the car is moving.

The technical result is achieved due to the fact that in the body of a covered freight car containing side walls, a roof, an internal ladder containing guide posts interconnected by crossbeams, the upper ends of the guide posts are bent to form hooks, according to the utility model inside the body in its upper part there is a U-shaped bracket rigidly fixed relative to the body, the guide racks in the lower part are rigidly connected to the spacers, which, on the other hand, are rigidly connected to the side wall of the body, the bent upper ends of the guide racks are engaged with the middle section of the U-shaped bracket, the ladder in the upper part on each side is equipped with limiters, each of which is rigidly connected to the corresponding guide post and its bent end, each limiter is located below the middle section of the U-shaped bracket at a distance from it, while the distance between the limiter and the middle section of the U-shaped bracket is selected from conditions of possible o moving the stairs in the vertical direction when the car is moving.

The U-shaped bracket can be rigidly attached to the roof of the body.

The U-shaped bracket can be rigidly attached to a beam fixed on the roof of the body.

The spacers can be made in the form of rods with bent ends, by means of which the spacers are rigidly attached to the guide posts on one side, and to the side wall of the body on the other side.

The limiter can be made in the form of a plate.

The claimed utility model is illustrated by drawings.

In FIG. 1 shows the placement of the ladder inside the body.

In FIG. 2 shows the top of the stairs.

In FIG. 3 shows the lower part of the ladder.

Positions on figures:

1 - side walls of the body;

2 - roof;

3 - guide racks;

4 - crossbars;

5 - bent upper ends of the guide posts;

6 - spacers;

7 - bent ends of the struts;

8 - limiter;

9 - beam;

10 - U-shaped bracket.

The inventive body of a covered freight car includes side walls 1, a roof 2, an internal ladder containing guide posts 3 interconnected by crossbeams 4, the upper ends 5 of the guide posts 3 are bent to form hooks. Inside the body in its upper part there is a U-shaped bracket 10 rigidly fixed relative to the body; guide rack 3 in the lower part is rigidly connected to the struts 6, which on the other hand are rigidly connected to the side wall 1 of the body; the bent upper ends 5 of the guide posts 3 are engaged with the middle section of the U-shaped bracket 10. The U-shaped bracket contains a middle horizontal section and two extreme sections that form an angle of 90 ° with the middle horizontal section or, possibly, an angle slightly greater than 90 °. The main thing is that the shape of the U-shaped bracket allows you to fix it relative to the body with extreme sections, and on a horizontal section it allows you to fix the ladder so that it cannot move (slide) along this section. The ladder in the upper part on each side is equipped with limiters 8 made in the form of a plate, each limiter 8 is rigidly connected to the corresponding guide post 3 and its bent end 5; each limiter 8 is located below the middle section of the U-shaped bracket 10 at a distance L from it, while the distance L between the limiter 8 and the middle section of the U-shaped bracket 10 is chosen by calculation from the condition of the possible movement of the stairs in the vertical direction when the car moves. The U-shaped bracket 10 can be rigidly attached to the roof 2 of the body or to the beam 9 fixed to the roof 2 of the body. The spacers 6 are made in the form of rods with bent ends 7, by means of which the spacers 6 are rigidly attached to the guide posts 3 on one side, and to the side wall 1 of the body on the other side. It is advisable to carry out all rigid connections by welding, as the most reliable form of connection of structural elements experiencing dynamic loads.

The fastening of the limiters 8 at a distance from the middle section of the U-shaped bracket 10 makes it possible to move the stairs in the vertical direction as a result of dynamic loads arising from the movement of the car. For this, the distance between the middle section of the U-shaped bracket 10 and the limiter 8 is calculated depending on the possible vertical movements of the ladder when the car moves. Those. placement of limiters 8 at a distance from the middle section of the U-shaped bracket 10 compensates for the dynamic loads acting on the stairs when the car is moving. In addition, the limiters 8 provide a rigid connection of the bent end 5 of the racks 3, preventing possible deformation (extension) of the bent ends 5 under the influence of dynamic loads during the movement of the car.

Thus, the probability of damage to the places of the rigid connection of the ladder with the body from dynamic loads is excluded, the probability of damage to the ladder and its attachment points is reduced, unlike the closest analogue, in which the ladder in the lower and upper parts is rigidly fixed relative to the body.
