Abstract

The subject matter of the invention is a tank wagon for transport of liquid products.
The tank wagon has a tank shell (3) which in its middle part has a narrowing formed by at least two conical parts (6) having their tops directed towards the middle of the tank (3).

Description

  • The subject matter of the invention is a tank wagon for transport of liquid products.
  • Previously used tank wagon for transport of liquid products has a tank in a form of a longitudinal cylinder with a horizontal axis, at both ends closed with convex heads, and an underframe on which the tank is seated. The underframe has end sills provided with buffing and draw gears. Length of the tank wagon and transverse dimensions are limited by international railway regulations. Permissible wagon width is not identical over the entire wagon length. Permissible minimum wagon width occurs in the middle of the wagon. For this reason external diameter of the cylindrical tank has to be smaller than permissible minimum wagon width. Moreover maximum wagon length is often limited by the requirements of the user.
  • The tank wagon known from other utility model, number Ru60353, has a tank equipped in the middle part with an insert. At the same time, the tank has one chamber and is inclined with respect to the horizontal plane at an angle of 1 degree in the direction of the central drain valve. The tank is seated on two saddles fixed permanently to two bolsters and is screwed on four shaped supports fixed permanently to underframe extreme parts, and the valve system is connected via a system of levers with a gas pendulum stub pipe for hermetic un/loading, with a T-pipe terminated with flange attachments, and moreover at both ends of the tank in the upper part of the tank heads there are hooks for lifting an empty tank.
  • The essential feature of the tank wagon, according to the invention, is such that the tank shell, in the middle part has a narrowing formed by at least two conical parts (cans) with their tops directed to the middle of the tank. The generators of the conical parts and cylindrical parts of the tank shell in tank lower part are situated along a straight line, or generators of the conical parts in tank lower part are situated at an obtuse angle.
  • The cylindrical part is seated favorably between conical parts.
  • Tank wagon for transport of liquid products, according to the invention, enables obtaining of the maximum tank volume capacity for the adopted length, thanks to the maximum utilization of permissible space defined by international railway regulations.
  • The subject matter of the invention in embodiment examples is depicted in the drawing where fig. 1 shows a tank wagon for transport of liquid products with conical and cylindrical parts of the tank shell at the bottom located along a straight line as viewed from the side, fig 2 tank wagon with conical parts in the lower part of the tank situated at an obtuse angle as viewed from the side, fig. 3 - tank wagon with conical parts separated by the cylindrical parts of the tank shell at the bottom situated along the straight line as viewed from the side and fig. 4 - tank wagon with conical parts separated by the cylindrical part, while the conical parts in the bottom section of the tank are situated at an obtuse angle.
    • Example 1
  • Tank wagon for transport of liquid products has underframe 1, seated on both bogies 2, on which a tank is seated. Underframe 1 is equipped with end sills 4 with buffing and draw gears 5 mounted thereon. The tank is seated axially on the underframe 1 and consists of the tank shell 3 having two conical parts 6 between cylindrical parts closed with convex heads 7, thanks to which the tank diameter is larger at its ends than in the middle. Such design of the tank enables enlarging of the tank volume capacity while maintaining, the same tank length. Shell parts are connected so as the generators of the conical parts 6 and cylindrical parts of the tank shell 3 in the bottom section of the tank are situated along a straight line. Moreover, the tank 3 has fittings 8 for tank filling and emptying and a manway 9 that is tightly closed with a separable cover 10.
    • Example 2
  • Tank wagon for transport of liquid products constructed as in the first example except that its generators of the conical parts 6 in the lower section of the tank are situated at an obtuse angle which ensures gravitational flow of product in the lower section of the tank during unloading.
    • Example 3
  • Tank wagon for transport of liquid products constructed as in the first example except that between the conical parts 6 there is a cylindrical part 11.
    • Example 4
  • Tank wagon for transport of liquid products constructed as in the second example except that there is a cylindrical par 11 seated between the conical parts 6.
