Description

The invention relates to railway transport and can be used in the construction of a boxcar for the carriage of passenger cars.

The known front door of a covered wagon contains the middle section and the corner section that are pivotally interconnected, which can be rotated 1 on the body rack.

However, the largest exit of the door being opened beyond the car's size is equal to the width of the door. In addition, pedestrian bridges that are located in the shops of the automotive factories and at the unloading bases are installed along the railway line. The height of the bridge deck above the car frame for the carriage of cars. The minimum distance between the bridges and the side wall of a boxcar is 270 mm. Therefore, the bridges prevent the full opening of these rotary doors.

The aim of the invention is to increase the safety of work on loading and unloading the car by allowing the smallest sections to go beyond its envelope when opening the door.

This goal is achieved by the fact that the front door of a covered car, containing a middle section hinged between themselves and an angle section, which is rotatably mounted on the body rack, is provided with an additional section hinged to the middle section, the width of each section being related to the door half width. doorway like

where the width of the corner, middle and additional sections, respectively; in - the width of the doorway.

FIG. 1 shows the gondola end view; in fig. 2 - front door in the “closed” position; in fig. 3 - the same, with one open section; in fig. 4 - the same, with two open sections; in fig. 5 is the same in the "open" position (the dotted lines in Figs. 2-5 show the intermediate positions of the sections).

The front door 1 of the body 2 of the covered wagon contains sections 3-5. The sections are connected to each other and with the corner post 6 O of the body by the hinges 7. The position 8 designates pedestrian bridges.

To open the end door, first turn the section 5 through 180 ° (Fig. 1-3). The largest output of the end of section 5 per g car size is L a3 (a, d, fB- (,

where L is the output of the end of the section behind the wall of the body;

j, 2,3j is the width of the first, second and third sections, respectively, starting from the corner stand;

in the half-width of the opening. After this, section 4 is turned 180 ° (FIG. 3). Section 5 then enters the gap between the side wall of the car 5 and the pedestrian bridges. The largest exit of the end of wall 4 beyond the car's dimension is

L ai-A, -fB - f in The latter turns 180 ° section 3 (Fig. 4 and 5). Sections 4 and 5 are moved along the side wall of the car. The largest exit for the car of the end of section 3 is equal to its width L 1/7 in.

With a body width of 3186 mm, the outflow of sections beyond the side wall of the body is 228 mm, which ensures the opening of the flaps with existing bridges.

Thus, due to the specified ratio of sizes, the smallest section sections reach the envelope when the door is opened.
