Description

Field of technology to which the utility model belongs

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

State of the art

From the patent of the Russian Federation No. 170765, a tank car is known, consisting of a frame, running gear, automatic coupling and brake equipment. The frame includes a spinal beam, frontal, side beams in the cantilever part. The side beams are made of a U-shaped profile - a channel, because on its upper shelves, the upper sheet of the pivot beam is additionally supported with the boiler support in the area of the pivot assembly.

The disadvantages of the described tank car is the additional support of the car frame nodes on the side beam, which creates in the zone of this contact additional areas for transferring hazardous vibration loads to the cantilever parts of the frame during the movement of the car, while the task of the side beams is to maintain the frontal beams in a stable and balanced state. beams.

Utility Model Disclosure

The technical result of the utility model is to increase the strength of the tank car in the cantilever parts of the frame, in particular, a more rational and uniform distribution of dynamic loads.

The claimed technical result is provided by a tank car containing a running gear, a frame installed on the running gear, and a boiler. The frame includes front beams and side beams, as well as supports. The boiler is mounted on frame supports.

A distinctive feature of the utility model is that the side beams are made of an L-shaped profile and are connected to the vertical wall of the frontal beam and the vertical wall of the support, while the thickness of the sheet of the L-shaped profile from which the side beams are made can be from 3 mm to 16 mm. The height of the side beams can be from 70 mm to 350 mm. The width of the side beams can be from 30 mm to 350 mm. The connection of the side beams with the frontal beam and the support can be made by welding along the contour of the L-shaped profile of the side beams. The side beams are preferably mounted with the shelf up. The side beams are preferably horizontal in the cantilever part of the tank car. The side beams are preferably arranged symmetrically with respect to the horizontal axis of the car.

Fig. 2 - general view of the semi-frame;

Implementation of the utility model

Further, with reference to the accompanying figures, one of the possible embodiments of the present utility model is described in detail. The tank car, the general view of which is shown in Fig. 1 comprises a chassis, which usually consists of bogies (not shown) and on which a frame 2 is mounted, and a boiler 1 mounted on a support 4, which is part of the frame 2.

The frame 2 of the tank car (Fig. 2) includes a center beam 5 (Fig. 2, 3) and in its cantilever part, frontal beams 3 (Fig. 2, 3) and horizontal side beams 6 (Fig. 2, 3) , which, as shown in Fig. 3 are symmetrically arranged with respect to the longitudinal axis of the tank car.

For the manufacture of side beams 6 (Fig. 2, 3), according to the utility model, an L-shaped profile is used, shown in section in Fig. 4. The side beams 6 are installed with one of the shelves up and connected to the vertical wall of the support and the vertical wall of the front beam 3 (Fig. 2, 3), for example, by welding along the contour of the L-shaped profile located with a short shelf up (that is, as shown in Fig. 4). Thanks to the L-shaped profile of the side beams 6, the metal consumption and labor intensity are reduced, the integration of the side beams 6 into the structure of the frame 2 is simplified due to the stability resource of the boiler support itself and the center beam of the semi-frame of the tank car with a more rational distribution of dynamic loads, in particular inertial loads arising when braking the tank car.

The thickness d of the sheet L-shaped profile (Fig. 4) can vary from 3 mm to 16 mm. When the sheet thickness of the L-shaped profile is less than 3 mm, it is impossible to weld the side beam 6 with the required strength. With a profile sheet thickness of more than 16 mm, an unreasonably high metal consumption of the assembly and the massiveness of the cantilever arise, which will provoke the bending of the cantilever, especially when it sways due to the impact of variable loads, and also lead to an overestimated tare weight.

The height h of the vertical flange of the L-shaped profile (Fig. 4), that is, the height of the profile of the side beam 6, is in the range from 70 mm to 350 mm. When the height of the vertical shelf of the L-shaped profile is less than 70 mm, the side beam 6 does not provide the necessary stability of its attachment in height to the vertical sheet of the frontal beam, and at a height of more than 350 mm, the side beam 6 will abut against the chassis elements.

The length a of the horizontal flange (Fig. 4), i.e. the width of the side beam 6, can vary between 30 mm and 350 mm. When the length of the horizontal shelf is less than 30 mm, the profile of the side beam 6 is not technologically advanced in manufacturing, especially at large thicknesses d of the profile, and also does not provide the necessary stability for fastening the side beam 6 when exposed to dynamic variable loads that occur in the cantilever part of the frame 2 during the movement of the tank car, and if the length of the horizontal flange of the side beam 6 is more than 350 mm, the indicated shelf will abut against the support elements 4 of the boiler (Fig. 3), in addition, an additional stress state will arise at the junction of the shelf of the L-shaped profile of the side beam 6 (Fig. 2, 3) with a horizontal sheet of the front beam 3 (Fig. 2, 3), which will provoke in the horizontal sheet of the front beam 3 undesirable variable bending stresses when the car moves.

The side beam 6 (Fig. 2, 3), made in the form of an L-shaped profile, supports the front beam 3 to prevent its vibration when the car moves and closes the frame structure into the console from the bottom of the boiler 1 (Fig. 2), forming a closed truss a structure around the wagon coupling unit to ensure the stability of the console during the movement of the tank car from the impact of the resulting variable dynamic loads and to ensure the safety of the wagon coupling.
