RAILWAY TANK FOR THE TRANSPORTATION OF LIQUID CARGOES.

The utility model relates to horizontal railway tanks, in particular to the design of tanks for transporting liquid cargo.

Railway tanks are known whose shells are made of three tsars (tank wagons, gondola cars, containers, tanks. Catalog. Ukraine. Mariupol. Advertising, from 10-12 (Azovmash company).

The closest technical solution to the proposed design of the tank is a railway tank for transporting liquid cargo (RF Patent No. 2074828 of 03/10/1997 B61D5 / 00), including a boiler installed in the chassis through the frame, in the form of a horizontal tank consisting of 2 bottoms and cylindrical shells made of 3 drawers, of which the ends are connected to the bottoms and freely placed on the frame, and the middle drawer by means of shaped paws is rigidly fixed to the frame and has a drainage device and a hatch. Each annular shch is made at a distance from the bottom equal to 0.15-0.3 of the distance of the total length of the shell, while the middle drawer is made of no more than four sheets. The shell of the drain housing is connected to the outer surface of the central collet T - shaped.

The disadvantage of this design is the large mass and not adaptability of the structure, the significant difficulty of its manufacture due to the presence of plinths of various lengths and the need to use expensive equipment for manufacturing the middle plinths and bottoms with an increased length of the cylindrical part, as well as the fact that the intersection of the welds are close leg supports and shaped legs, which reduces the reliability of the structure due to stress concentration.

The objective of the utility model is to increase the manufacturability of the tank, reduce the complexity, reduce the cost of its manufacture and increase reliability, as well as weight reduction.

in accordance with the developed utility model, the railway tank includes a frame with a boiler made in the form of a horizontal cylindrical tank. The boiler frame is mounted on a trolley. The cylindrical capacity of the boiler consists of two bottoms and a cylindrical shell, made of three tsars. Each collet is made of four sheets: one lower armor plate of increased thickness, two middle and one upper.

In the proposed tank, the drawers are made of the same length equal to 3.1 mi and are composed of sheets so that at the extreme drawers the size of the armor plate is not less than 200 mm greater than the length of the armor plate of the middle drawer. Shaped paws are attached to the boiler tank, so that the distance from their ends to the annular seams is at least 150 mm.

In FIG. 1 shows a General view of the proposed railway tank for transporting liquid cargo. In FIG. Figures 2 and 3 show the cutting of the shells of the extreme and central tsars, respectively. In FIG. 4 - installation of a drain device.

The railway tank for transporting liquid cargo (Fig. 1) contains the chassis 1, the frame of the car 2 and the boiler in the form of a horizontally located container assembled from three drawers 3, 4 and two bottoms 5. From the end of the boiler, the end drawers 3 are connected to the bottoms 5. The drawbars (Fig. 2,3) are made up of three sheets of armor plate b middle 7 and top 8. The shell 9 of the body 10 of the drain device of the proposed tank is installed in the hole of the armor plate b of the central drawer flush with its inner surface, which provides additional weld tightness wow seam. (figure 4).

Tsag blanks are cut and cut to size on appropriate devices, joined together by tacks, then the edges and heat-affected zones are cleaned and welded with butt welds under a flux layer on a flux cushion. The assembled tsar 3.4 are rolled in rolls with hem edges, which are then tacked and welded end-to-end by automatic welding on both sides.
