Description

Emphasis for a gondola hatch cover

The inventive utility model relates to railway transport, in particular, to gondola cars with hatches in the floor of the body, and relates to devices designed to keep the manhole covers open for unloading bulk cargo.

Known emphasis for the hatch of the gondola [SU 331950 A1, publ. 03/14/1972] containing a vertical welded and horizontal supporting flange, while the vertical welded flange is made of a Z-shaped profile. Its disadvantages are complexity, metal consumption and increased complexity of manufacturing due to the use of a Z-shaped profile.

Known stamped stop for manhole covers universal gondola [RU 96355 U1, publ. 07/27/2010], mounted on the hatch cross beams, having two L-shaped brackets interconnected, enveloping the lower belt of the transverse beam and reinforced in the lower part by overhead welded squares, to which a connecting sheet is welded perpendicular to the brackets.

Known emphasis for the hatch of the gondola car is selected as a prototype. However, the disadvantages of this design of the stops are that they are significantly developed in the vertical direction, which does not allow them to be used to support the hatches above the trolleys, have a complex structure, high weight and low reliability of fastening the brackets to the gondola car frame.

The technical result of the proposed utility model is to reduce the vertical dimensions of the brackets while increasing the manufacturability of the manufacturing process and assembly of stops, as well as reducing their metal consumption.

The specified technical result is achieved in that the emphasis for the gondola hatch mounted on the gondola car body frame contains two L-shaped support brackets connected by a connecting element located perpendicular to the brackets. At the same time, the brackets are turned 90 degrees downward and are located with short faces towards each other.

In options:

- the connecting element is made with the possibility of welding with the bottom sheet of the pivot beam of the gondola car body frame;

- supporting brackets are made with the possibility of welding them with the bottom sheet of the pivot beam of the gondola car body frame;

- the connecting element at the edges has cutouts, with the surface of which the brackets join with their corners;

- cutouts of the connecting element are L-shaped;

- bevels are made at the lower ends of the cutouts of the connecting element;

- a cutout is made in the central part of the connecting element;

- a hole is made in the central part of the connecting element;

- the vertical dimension of the support bracket is in the range of 30 - 300 mm;

- the vertical dimension of the connecting element is in the range of 40 - 330 mm.

Thus, the proposed design of the stop for the hatch of the gondola allows you to make and assemble it using fewer assembly operations compared to the prototype and, therefore, in less time. At the same time, due to the reduction and simplification of parts, a reduction in the metal consumption of the entire structure is also achieved. At the same time, reducing the vertical dimensions of the brackets allows them to be installed in a limited space above the gondola carriages with reliable fastening to the bottom sheet of the pivot beam.

The proposed utility model is illustrated by graphic material, where in FIG. 1 shows a front view of a stop for a gondola hatch; in FIG. 2 shows a top view of the stop for the gondola hatch, in FIG. 3 shows a side view of the stop for the gondola hatch, in FIG. 4 and 5 show the installation of the stop for the hatch of a gondola car.

The emphasis for the hatch of the gondola car (Fig. 1-5) contains two supporting brackets 1 L-shaped, interconnected by a connecting element 2 located perpendicular to the brackets 1 and acting as a stiffener. In this case, the brackets 1 are rotated 90 degrees downward and are located with short faces towards each other.

Both the connecting element 2 and the supporting brackets 1 can be made with the possibility of welding with the bottom sheet 3 of the pivot beam of the gondola car body frame.

The connecting element 2 at the edges can have cutouts 2.1, with the surface of which the brackets 1 are joined at their corners. In this case, the cutouts 2.1 can have an L-shaped shape. Those. mating with the brackets 1 of the surface of the cut-outs 2.1 are of the reciprocal form, repeating the shape of the brackets 1.

The connecting element 2 can be made in the form of a sheet or rib. To further reduce the metal consumption, the bevels 2.2 can be made at the lower ends of the cutouts 2.1 of the connecting element 2, and a cutout 2.3 and / or hole can be made in the central part of the connecting element 2 (not shown in the drawing).

In this case, the vertical dimension of the support bracket 1 (size a in Fig. 3) may be in the range of 30 - 300 mm. And the vertical dimension of the connecting element 2 (size b in Fig. 3) may be in the range of 40 - 330 mm. The distance between the brackets 1 is determined by the size of the bottom sheet 3 of the pivot beam.

In the manufacture of the stop for the gondola hatch, two L-shaped support brackets 1 are welded to each other using a connecting element 2. After that, the resulting structure is mounted on the pivot beam of the gondola car frame. The connecting element 2 during installation is welded with its upper end to the bottom sheet 3 of the pivot beam of the gondola car frame. In addition to the bottom sheet 3 of the pivot beam, the upper parts of the support brackets 1 can be welded.

In the open position, the manhole cover 4 rests on the support brackets 1 and remains in a fixed position until the discharge is complete (Fig. 5).

Thus, the proposed design of the emphasis for the hatch of the gondola allows to reduce the vertical dimensions of the brackets while increasing the manufacturability of the manufacturing process and assembly of the stops, as well as reducing their metal consumption.
