Description

The utility model relates to the field of railway transport and is intended for use in the construction of open-type freight cars (platforms) designed to transport long goods that do not need to be protected from atmospheric precipitation, in particular, for transportation of timber.

Known end wall of a flatcar for transportation of timber and lumber, attached by transitional brackets to the end beam of the frame using clamps and to the upper shelves of the side beams - using bolts (see patent RU 61662, IPC B61D 3/08, published. 03/10/2007 ) The known end wall extends beyond the frontal part of the platform frame in the longitudinal direction, thereby increasing the loading length. However, this constructive solution is complicated by the use of transitional brackets, and the mounting of these brackets on the end beams of the frame excludes the possibility of installing carriage equipment on the end beams.

The end wall of the platform for transporting timber was adopted as the closest analogue. The end wall has a lattice structure in the form of transverse beams (horizontal belts) and vertical rods, it is connected to the extreme forest stands by jumpers and to the car frame by means of additional stops placed on the end beams of the frame (see patent RU 38465, IPC B61D 3/08 , published on 06/20/2004). The known end wall by connecting it to the end beam of the frame partially blocks access to the surface of the end beam, thereby making it difficult to place the release lever, handrails, etc. on the end beam.

The technical result of the proposed utility model is to increase the loading volume of the flatcar by increasing its loading length.

This technical result is achieved in that the end wall of the platform car, as in the closest analogue, is made with horizontal belts and has a connection with the extreme forest stands. The difference is that the end wall is fixed at the ends of the side beams of the frame, which are extended in the longitudinal direction beyond the end beam of the frame, and the horizontal belts of the end wall are evenly placed on the sheathing sheet and are made with a cross-sectional profile that decreases in height towards the lateral vertical edges end wall. The distance at which the ends of the side beams are made relative to the frontal sheet of the end beam of the frame does not exceed 340 mm. A cutout of a rectangular or trapezoidal shape with a height of at least 100 mm and a width of the lower base of at least 300 mm is made in the lower central part of the end wall.

By fixing the end wall at the ends of the elongated side beams, which (the ends) are extended in the direction from the center of the platform along its longitudinal axis outside the end beam of the frame, an increase in the internal loading length of the platform and an increase in its capacity are achieved. The proposed removal of each of the end walls of the platform allows you to transport cargo of increased length.

Fixing the end wall on the side beams of the frame, which are elongated beyond the end beam of the frame, is most appropriate. This solution leaves the end beams free to accommodate the release arms, handrails and other equipment, and also does not burden the frame structure.

The distance by which the ends of the side beams are made relative to the front sheet of the end beam of the frame corresponds to the amount of removal of the end wall, measured from the front sheet of the end beam of the frame to the projection of the outer surface of the central part of the horizontal belt on the longitudinal axis of the platform. The limit value of the end wall removal, equal to 340 mm, was calculated from the condition of guaranteed exclusion of contact of the lateral vertical edges of the end walls of two adjacent platforms when the composition of the cars passes curved sections of the track with a small radius. For the same purpose, the horizontal belts of the end wall are made with a variable section of the profile, the height of which decreases in the direction of the lateral vertical edges of the end wall. This design of horizontal belts also allows, along with ensuring the strength and rigidity of the end wall, to reduce the metal consumption of horizontal belts and reduce the mass of the end wall compared to the use of horizontal belts with a constant profile section height.

The proposed design of the end wall is presented on graphic materials, which depict:

in FIG. 1 - end wall of a platform car, front view;

in FIG. 2 - end wall of a platform car, side view;

in FIG. 3 - end wall, fixed at the ends of the side beams of the frame, axonometric projection.

The end wall of the platform car (Fig. 1, 2) contains a sheathing sheet 1 and horizontal reinforcing belts 1.1 evenly placed on it. The profile height of the horizontal belts 1.1 is made the greatest in the central part of the end wall and decreasing towards its lateral vertical edges. In the lower central part of the sheathing sheet 1 there is a cutout 1.2 of a rectangular or trapezoidal shape with a height of up to 100 mm and a width of the lower base of up to 300 mm.

By welding, sidewalls are connected to the lateral vertical edges of the end wall by welding, consisting of a sheathing sheet 2 with side beams 2.1 and intended for fastening the end wall to the extreme forest racks 3.

The side beams 4 of the frame (Fig. 3) are elongated, for which their ends are extended in the longitudinal direction relative to the frontal sheet of the end beam 5. At the ends of the side beams 4, an end wall is fixed by means of a welded joint.

The utility model works as follows.

In two adjacent platform cars, the end walls, due to their removal beyond the end beams of the frame, are located closer to each other by at least 680 mm, in comparison with the option of fixing the end walls on the end beams of the frame. At the same time, at the moments of the passage of the composition of the curved sections of the small radius path, due to the optimal end wall extension and the optimized profile height of horizontal belts 1.1, the probability of contact of the lateral vertical edges of adjacent end walls and the lateral corners of their horizontal belts is excluded. The likelihood of contact of the edges of the end wall cutout 1.2 with the socket and the front stop of the coupler at the moments when the composition of the recesses of the vertical profile of the path and the curved sections of the path of small radius is excluded is also eliminated due to the implementation of cut 1.2 with a height exceeding 100 mm and a width of the lower base exceeding 300 mm .
