Description

The technical field to which the utility model belongs

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

State of the art

From the patent for invention RU 2118598 C1, a railway tank car for transporting liquid cargo is known, containing a boiler made with a broken axis. The boiler of the tank car contains end and middle sides of the boiler shell, connected by welding seams, two end bottoms welded to the end sides of the shell, and a manhole located in the upper part of the boiler and equipped with a lining installed on the seam between the middle sides, and the middle sides cylindrical shells are made with a slope of 1-3 ° towards the middle of the boiler to accelerate the unloading and complete drainage of the transported liquid. The main disadvantage of such a boiler is the large gap between the hatch cover and the boiler shell, as well as the low manufacturability of the boiler due to the fact that the hatch cover is installed on an annular seam connecting the middle sidewalls of the shell, with the formation of a gap between the hatch cover and the outer surface of the middle sidewalls due to their location at an angle to each other.

Disclosure of the essence of the utility model

The technical result of the utility model is to increase the manufacturability of manufacturing, as well as the operational properties of the boiler of the tank car.

The claimed technical result is provided by the boiler of the tank car, containing a shell, consisting of welded sidewalls, the middle of which are located at an angle to each other, and made with a broken axis, and a manhole located in the upper part of the boiler above the junction of the middle sidewalls and reinforced with a lining fixed on the outer surface of the shell and covering the opening of the manhole. According to the utility model, the hatch cover is made of two parts, located at an angle to each other and connected to each other by a welding seam extending substantially parallel to the weld seam between the middle sides of the shell.

Preferably, the angle between the portions of the hatch cover is substantially equal to the angle between the middle side frames.

Preferably, the weld joining the parts of the hatch cover is offset relative to the weld joining the middle sides of the boiler shell by a distance of 20 to 100 mm.

In one embodiment, one of the parts of the hatch cover is wider than the other, the width of the narrow part of the cover being from 240 to 340 mm, and the width of the wide part of the cover being from 440 to 625 mm.

Implementation of the utility model

An implementation of the invention is described in detail below with reference to the accompanying figures. The tank car shown in Fig. 1 includes a boiler containing a shell 1, consisting of middle side bars 1.1 and end side bars 1.2, connected by welding seams 4, and a manhole 3 located in the upper part of the boiler. As shown in FIG. 2, in addition to shell 1, the boiler contains two end bottoms 2, welded to shell 1.

излома оси (см. фиг. 5) для обеспечения полноты слива транспортируемой среды, при этом смежные центральные царги 1.1 обечайки 1 котла, шов между которыми находится в области расположения люка-лаза 3, расположены под углом друг к другу, равным 180° -

.In the upper part of the boiler there is a manhole 3, as shown in detail in Fig. 3 and 4, equipped with a cover plate 6 of the hatch located between the hatch 3 and the shell 1 of the boiler and welded along the perimeter to the shell of the boiler. The boiler of the tank car is made with a broken axis at an angle

fracture of the axis (see Fig. 5) to ensure the completeness of draining the transported medium, while the adjacent central sides 1.1 of the shell 1 of the boiler, the seam between which is located in the area of the hatch-manhole 3, are located at an angle to each other equal to 180 ° -

...

To improve the manufacturability of the boiler, made with a broken axis, in particular in order to reduce the gap between the hatch cover 6 and adjacent middle drawers 1.1 of the boiler shell 1, the hatch cover 6 is made of two parts 7, 8 (see Fig. 4). In this case, part 7 of the cover plate 6 of the hatch is made narrower than the wider part 8 of the cover plate 6. Parts 7, 8 of the cover plate 6 of the hatch are located on the shell 1 of the boiler in the area of the weld between the middle side arms 1.1 of the shell 1 and are welded at an angle to each other, the angle of inclination of the parts 7, 8 of the cover plate 6 of the hatch essentially corresponds to the angle of inclination of the corresponding sidebars 1.1 of the shell 1 of the boiler. Thus, the angle between the parts 7, 8 of the strap 6, measured in the vertical plane, is substantially equal to the angle between the middle side arms 1.1 of the shell 1 of the boiler, while the weld 5 connecting the parts 7, 8 of the strap 6 runs substantially parallel to the welding seam 4 between the middle drawers 1.1.

The implementation of the hatch cover 6 from two parts 7, 8 increases the convenience when welding the hatch cover 6 to the middle side rails 1.1 of the shell 1 and, thus, increases the manufacturability of the tank boiler by reducing or even completely eliminating the gap between each of the parts 7, 8 of the cover 6 hatch and corresponding side bar 1.1 of shell 1.

Parts 7, 8 of the cover plate 6 of the hatch are connected to the shell 1 along the outer perimeter of each of the parts 7, 8 of the cover plate 6, i.e. both along the outer edge of the lining 6 and between each other along the weld 5 (see Fig. 5). This increases the total length of the weld seam holding the hatch cover 6 on the shell 1, which increases the strength of the fastening of the hatch cover 6 3 on the boiler shell 1 and, thus, increases the operational properties of the tank car.

Parts 7, 8 of the patch 6, as shown in FIG. 3 and 4 are interconnected by a welding seam 5. The seam 5 can extend substantially along the weld 4 joining the middle side arms 1.1 of the shell. In this case, a minimum clearance is provided between each of the parts 7, 8 of the cover plate 6 of the hatch 3 and the corresponding middle side arms 1.1 of the shell 1. However, it is preferable that the welding seam 5 connecting the parts 7, 8 of the cover plate 6 of the hatch is made at a distance (with an offset ) l from the weld 4, connecting the middle side arms 1.1 of the shell 1 (see Fig. 4), and the specified distance l is preferably from 20 to 100 mm, while the assembly weld between the middle side arms 1.1 is preferably covered by the narrow part 7 of the overlay 6 Such a seam between the parts 7, 8 of the lining 6 helps to increase the strength of the junction of the parts of the lining 6 of the hatchway 3 with the shell 1 while maintaining a minimum gap between the narrow part 7 of the lining 6 and the shell 1. The width L1 of the narrow part 7 of the lining preferably has a value from 240 to 340 mm, and the width L2 of the wide part 8 of the patch is preferably 440 to 625 mm.

Implementation of the tank car boiler according to the present utility model increases the manufacturability of the boiler, as well as its operational properties.
