The utility model relates to railway equipment, and more specifically to horizontal tanks, and can be used for transportation of petroleum products, including viscous ones.

A railway tank for transporting liquid goods is known, including a boiler mounted on the chassis by means of a frame in the form of a horizontal tank consisting of elliptical bottoms and a cylindrical shell made of three legs, the end of which are connected to the bottoms and placed on the frame supports, and the middle side is the shaped paws are rigidly fixed to the frame and has a hatch and a drain device, and each tsar of the cylindrical shell is made of interconnected upper and lower armor plates so that shenie thickness of the upper sheet to the lower armor is 1: 1.2.

The disadvantages of the known technical solutions include low load capacity and low performance.

The closest technical solution is a railway tanker for transporting liquid cargo, containing a boiler with two elliptical bottoms, a hatch, a safety-inlet valve, a drain device, braking equipment and a running gear, and equipped with an additional tank rigidly fixed to the boiler in its lower part, and two semi-frames connected to the boiler by means of pivot and spinal tool beds and mounted on biaxial bogies of the tank chassis. In this case, the tank drain device is installed in

additional capacity, and each carriage of the chassis of the tank is made with autonomous brake equipment. Moreover, the additional capacity is made of a half-shell with conical transitions along the ends and is installed with an offset relative to the horizontal axis of the boiler. The frames are installed on the inner and outer surfaces of the boiler, and protective shields are rigidly fixed to the bottoms of the boiler. [RF patent 2197400 MKI 7 B61D 5/00, B65D 88/12. Railway tank for transporting liquid cargo. Author Burmistrov N.V. Publ. January 27, 2003].

This railway tank is selected by the authors as a prototype.

A disadvantage of the known technical solution is that the tank is equipped with an additional tank that communicates with the boiler of the tank through a small oval hole in the lower part of the boiler, which complicates the technology and increases the complexity of the washing and steaming of the additional tank, especially when using such a tank for transportation viscous petroleum products.

The technical result is an increase in the carrying capacity of a railway tank for transporting liquid cargo, including viscous petroleum products, by increasing the average shell side of the boiler along a vertical axis perpendicular to the horizontal plane of the frame.

The technical result is achieved by the fact that the proposed railway tanker for transporting liquid cargo, including mounted on two bogies of the chassis, each of which contains two, three or four axles, braking equipment and, through two half-frames with pivot and spine tool holders, is a boiler, which is a horizontal tank consisting of

shells with the upper, middle and lower parts vertically made of the middle side and two end sections connected to elliptical bottoms, the hatch, safety inlet valve and drain device are made with the enlarged size of the lower part of the middle side of the boiler shell along the vertical axis perpendicular horizontal plane of the frame, by 0.05-0.30, for example, from the size of all parts of the middle shell of the boiler shell at the same time, while the increase in the size of the lower part of the middle shell of the boiler shell is determined by the ratio m , where ΔН of the _{part of the czar} is the magnitude of the increase in the size of the lower part of the middle czar of the boiler shell along the vertical axis, P _add.os. - permissible axial load of the proposed tank, R _OS. - axial load of the tank, N _{parts of the middle of the collet} - the size of the parts of the middle shell of the boiler shell along the vertical axis, and the increased part of the middle shell of the boiler shell is made with a flat or curved transition to adjacent parts, and the end shells are mounted with an axis inclined at an angle of 6 ° towards the drainage device of the boiler or without tilting the axis with conical transitions in the lower part from the bottoms of the boiler to the middle side with a slope towards the drainage device of the boiler, while the end sections are connected to the middle side with an elliptical adapter and adapters, or in the form of a truncated cone.

The difference between this technical solution and the prototype is that to eliminate the additional capacity made of semi-shells with conical transitions at the ends and communicating with the boiler through a small oval hole in its lower part, to increase the load capacity of the tank, the lower part of the middle shell of the boiler shell is increased along the vertical axis perpendicular to the horizontal plane of the frame, by 0.05-0.30, for example, of the size of all

parts of the middle shell of the boiler shell of the tank at the same time, while the increase in the size of the lower part of the middle shell of the boiler shell is determined by the ratio , where ΔН of the _{part of the czar} is the magnitude of the increase in the size of the lower part of the middle czar of the boiler shell along the vertical axis, P _{add.os. -} permissible axial load of the proposed tank. R _os. - axial load of the tank, N _{parts of the middle of the collet} - the size of the parts of the middle shell of the boiler shell along the vertical axis, and the increased part of the middle shell of the boiler shell is made with a flat or curved transition to adjacent parts, and the end shells are mounted with an axis inclined at an angle of 6 ° to the side, the drain device of the boiler or without tilting the axis with conical transitions in the lower part from the bottoms of the boiler to the middle side with a slope towards the drain side of the boiler, while the end sections are connected to the middle side with an elliptical adapter or truncated cone adapters.

Thus, the coefficient of increase in the size of the lower part of the middle shell of the boiler shell vertically , characterizing the ΔН value _{of the middle czar’s part} , by which the size of the middle casing side of the boiler shell has been increased vertically, due to the permissible axial load of the tank, has a value in the range from 1.05 to 1.30 and can be calculated by the formula , where N of the _{part of the middle cis} is the size of the part of the middle shell side of the boiler shell of the known tanks vertically; R _add.os. - permissible axial load of the proposed tank; R _os. - axial load of known tanks. That is, the size of the lower part of the middle shell of the boiler shell of the proposed tank according to

the vertical axis is larger than the size of the lower parts of the known tanks by 5-30% of the vertical size of the middle side of these tanks.

The carrying capacity and the coefficient of increase in carrying capacity of the proposed tank can be calculated by the formulas

and ,

where M _gr. - carrying capacity of the proposed tank; M _tare - _tare weight of the proposed tank; N _axes - the number of axles of the proposed tank; M _gr. - carrying capacity of known tanks.

As an example, we consider how much the size of the middle shell side of the boiler shell of the proposed tank will increase vertically with an allowable axial load P _add.oc. = 25 ... 30 tc. To do this, we calculate the coefficient of increasing the size of the lower part of the middle shell of the boiler shell vertically according to the proposed formula. He will make . That is, the size of the lower part of the middle shell of the boiler shell of the proposed tank along the vertical axis will increase by 7 ÷ 29%.

In this case, the coefficient of increase in carrying capacity for a four-axle tank will be

,

where approximately we take the values of M _tare = 27 ÷ 28 t. That is, the carrying capacity of the proposed tank, for example, with four axles, will increase by 11 ÷ 39%.

Let us consider how much the volume and load capacity of a four-axle tank with an axial load of 25 axles with a boiler shell diameter of 3200 mm, a boiler length of 11240 mm, a useful boiler volume of 84.18 m ³ and a load capacity of not more than 72 tons increase with an increase in the size of the lower

parts of the middle shell of the boiler shell along the vertical axis perpendicular to the horizontal plane of the frame, 0.05-0.3 of the vertical size of the middle shell of the boiler shell of the tank.

With an increase in the size of the lower part of the middle shell of the boiler along the vertical axis perpendicular to the horizontal plane of the frame by 0.05 of the vertical size of the middle shell of the shell of the tank, the size of the lower part of the middle shell of the boiler will increase by 160 mm with a length of 4400 mm, the volume of the boiler increase by 2.25 m ³ , carrying capacity will increase by 1.94 tons; with an increase of 0.10, the size of the lower part of the middle shell of the boiler shell will increase by 320 mm, the volume of the boiler will increase by 4.42 m ³ , the carrying capacity will increase by 3.80 tons; with an increase of 0.15, the size of the lower part of the middle shell of the boiler shell will increase by 480 mm, the volume of the boiler will increase by 6.59 m ³ , the carrying capacity will increase by 5.67 tons; with an increase of 0.20, the size of the lower part of the middle shell of the boiler shell will increase by 640 mm, the volume of the boiler will increase by 8.76 m ³ , the carrying capacity will increase by 7.53 tons; with an increase of 0.30 - the size of the lower part of the middle side of the shell of the boiler will increase by 960 mm, the volume of the boiler will increase by 12.69 m ³ , the carrying capacity will increase by 10.9 tons.

figure 3 is a section of the shell of the boiler of the proposed tank along the vertical axis with a curved transition from the lower part of the shell to the upper, where H _cf. ΔH _cp.tzar - the size of the increase in the size of the lower part of the middle side of the shell

along the vertical axis perpendicular to the horizontal plane of the tank frame;

figure 4 - open the shell of the boiler tank with adapters in the form of a truncated cone.

The railway tank (Fig. 1) for transporting liquid cargo consists of carts 1 of the chassis, two semi-frames 2 with pivot 3 and spinal 4 lodgements and a boiler 5 in the form of a horizontally located container consisting of two ellipsoid bottoms 6 and a cylindrical shell 7 with the upper part 8, the middle part 9 and the lower part 10, made of two end sections 11 of an elliptical cross-section, mounted with an inclined axis at an angle of 6 ° towards the drain device of the boiler, the middle section 12, which is made with an increased vertical size axle ΔH _cp.tzar and two adapters 13 in the form of a truncated cone, a manhole 14 with a cover, a safety inlet valve 15, a drain device 16, two ladders 17 with handrails in the upper part, platforms 18 with barriers and brake equipment 19.

The boiler is a welded structure, consisting of two elliptical bottoms 6 and a shell, with the upper part 8, the middle part 9 and the lower part 10, made of the middle collet 12 and two end collet 11 connected to the ellipsoidal bottoms 6, while the size of the middle tsargi proposed tank shell 12 on the vertical axis H _cp.tsargi increased by an amount ΔH _cp.tsargi by increasing the size of the bottom of the middle tsargi boiler shell along the vertical axis, which is due to the permissible axial load and is within rANGES to 0.05 to 0.30 times the size of the boiler shell known tanks vertically, while the increased mean side-bar 12 is formed with a curved mantle (3) the transition from the bottom 10 to the upper shell portion 8 and the end 11 mounted tsargi

by tilting the axis at an angle of 6 ° towards the drainage device of the boiler 16, while the end sections 11 are connected to the middle section 12 by elliptical adapters (FIG. 2, a) or adapters in the form of a truncated cone 13 (FIG. 2, b).

Opening the shell of the boiler tank (figure 4) is a shell of the middle drawer 12 and two end drawer 11, and two conical shell 13 of the adapter in the form of a cone.

An increase in the size of the lower part of the middle shell of the shell of the tank boiler along the vertical axis perpendicular to the horizontal plane of the frame by 0.05-0.30, for example, from the size of all parts of the shell at the same time, can significantly increase the volume of the boiler and the carrying capacity of the tank, improve operational and commercial indicators in comparison with the known tanks, while maintaining the basic overall dimensions of the rolling stock, provided for by the technical requirements for new generation tanks.

The proposed technical solution allows to increase the carrying capacity by 11 ÷ 39% by increasing the size of the lower part of the middle shell of the shell of the boiler boiler vertically by 7 ÷ 29%, reduce labor costs during the operation of the tank, expand the range of transported liquid cargo and ensure the improvement of the commercial qualities of the railway tank.

Increasing the lower part of the middle shell of the boiler shell vertically and using adapters in the form of a truncated cone to connect with the end shells will make it possible to reduce the center of gravity of the tank and increase the safety of its operation.

Due to the increase in the volume of transported goods and a decrease in the center of gravity, the stability coefficient of the tank increases.
