Description

The utility model relates to railway transport, in particular, to the design of drain devices of railway tanks of a frame structure for transporting liquid cargoes, in which three sequentially installed and independently controlled shutters are provided.

Known drain devices of railway tanks for transporting liquid cargo (patents RU No. 2182091, B 61 D 5/00, B 67 D 5/02 dated 04/27/2001, No. 2185982, B 61 D 5/00, B 65 D 90/54 from 04/27/2001, No.41685, B 61 D 5/00, B 65 D 53/00 dated 05/24/2004).

In these designs, the drain device is made in the form of three sequentially installed and independently controlled valves. Moreover, in each of the known solutions, an intermediate valve is installed between the main valve located in the lower part of the tank in the area of the drain hole and an additional valve located at the end of the drain pipe and is located in the inner cavity of the spine beam.

A drain device of a railway tank is also known, in which an intermediate shutter with a worm gear drive connected to it is placed in the inner cavity of the spine beam between the flanges of the drain pipe parts, and the drive control shaft is brought out of it and passes through an opening made in

the vertical wall of the spinal beam (patent RU No. 46253, B 61 D 5/00 from 01/31/2005 - adopted as a prototype).

A disadvantage of the known solutions is the impossibility of retrofitting the existing fleet of railway tanks with an intermediate shutter without dismantling the boilers, since in all frame structures the intermediate shutters with their control drives are located in the internal cavity of the spine beam.

The utility model is based on the task of creating a drain device for a railway tank, which makes it possible to retrofit an existing fleet of railway tanks with an intermediate shutter without dismantling the boiler.

To solve this problem, a drainage device is proposed that includes sequentially located and independently controlled valves, the main of which is located in the internal volume of the boiler in the area of the lower drainage hole, a drain pipe divided into two parts equipped with flanges, an intermediate valve installed between the flanges and equipped with an actuator with gear, and a shutter located at the end of the drain pipe. A feature of the drain device is that the intermediate shutter is installed under the lower plane of the spinal beam, while the distance from the flange of the upper part of the drain pipe to the lower plane of the spinal beam is 0.08-0.05 of the diameter of the drain pipe, and the profile of the central hole of the flange is made in in the form of two spaced cylindrical grooves, the lower of which is made of a smaller diameter and is connected to the upper at an acute angle.

The control of the intermediate shutter drive can be made in the form of a cardan shaft, the free end of which is perpendicular to the longitudinal axis of the railway tank.

The essence of the utility model is illustrated by drawings, where:

figure 1 shows a General view of the drain device;

figure 2 is a section aa in figure 1;

figure 3 is a section aa in figure 1 (option);

figure 4 is a section bB in figure 2, 3;

figure 5 - remote element in figure 4.

The drain device of the railway tank is located in its lower part and is made in the form of three sequentially located and independently controlled gates 1, 2, 3.

The shutter 1 is the main one and is located in the internal volume of the boiler 4 in the area of the drain hole.

The shutter 2 is optional, located at the end of the drain pipe 5.

The shutter 3 is intermediate, located in the middle of the drain pipe 5 between its upper 6 and lower 7 parts.

The upper and lower parts of the drain pipe are equipped with flanges 8 and 9. The flange 8 is spaced from the lower plane 10 of the spine beam 11 at a distance h = 0.05-0.08 of the diameter of the drain pipe 5. The profile of the central hole of the flange is made in the form of two spaced apart cylindrical grooves 12 and 13, moreover, the lower groove is made of smaller diameter and connected to the upper at an acute angle α.

Such a profile makes it possible to expand the seating surface of the flange 8 and to better perform the weld 14 of its connection with the pipe 15.

The intermediate shutter is controlled by a gear drive 16, on the control shaft 17 of which the steering wheel 18 is fixed.

The control of the intermediate shutter drive can be made in the form of a driveshaft 19, the free end of which 20 is perpendicular to the longitudinal axis of the railway tank. This gives

the ability for the operator to face the product when servicing the drain device.

The proposed constructive solution allows for the completion of the third shutter without dismantling the boiler of the existing fleet of railway tanks with drain devices equipped with two shutters. In addition, the proposed drain device provides high maintainability.

Retrofitting is performed as follows: the drain pipe 5 is cut below the lower plane 10 of the spine beam 11 into two parts 6 and 7 so as to ensure installation at a distance h and weld the flange 8 to the pipe 15. In this case, the total length of the drain pipe must be maintained, to ensure a guaranteed fit of the railway tank into the lower outline of the installed size of the rolling stock. After performing the weld 14, an intermediate shutter 3 is installed between the upper 6 and lower 7 parts of the drain pipe.

According to the proposed solution, the first batch of railway tanks for the transportation of petroleum products is being retrofitted.
