Description

The invention relates to freight cars of railway transport and for a tank car intended for the transportation of liquid, including liquefied, goods and, in particular, liquefied hydrocarbon gases, as well as a composition formed from such tank cars.

Four-axle tank cars for transporting liquefied hydrocarbon gases are known, including a supporting frame, two biaxial carts, two automatic couplers, brake equipment and a boiler mounted on the frame with a manhole, a closed lid, on which a safety, control and discharge tank is placed fittings (see the Album-reference book “Freight cars of railways of 1520 mm gauge 002I-97 PKB CV” - M .: MPS, 1998, p.229-235). The length of tank cars along the clutch axes of automatic couplers is 12020 mm and is determined by the design features of the discharge terminals.

The disadvantage of these tank wagons is the insufficient volume of the boiler to accommodate the transported cargo, caused by the overall restrictions applied on the railways, and, as a result, the underestimated value of the carrying capacity indicator.

A tank car for transporting liquefied gases is also known (see patent for utility model RU 24668 U1, publ. 08/20/2002). This tank car includes a frame mounted on running gears, automatic couplers, brake equipment and a boiler with a safety valve mounted on the frame, while the length along the clutch axes of automatic couplers is 15235-16500 mm.

The disadvantage of this tank car is the increased time for loading and unloading cargo at the loading and unloading terminals, due to the need for additional shunting operations to unhook the composition of such tank cars supplied for draining or loading and their subsequent positioning under the discharge or loading devices.

Also known is a tank car for transportation of liquefied gases (see patent for utility model RU 96081 U1, published on July 20, 2010). This tank car includes a frame with a running gear, automatic couplers and brake equipment. A boiler is installed on the frame, which is equipped with a manhole mounted on the central vertical axis of the car, a cover with safety and control valves, two sets of drain and bulk valves, protective casings, stairs with a service platform, protective arcs. Drainage and loading reinforcement kits are symmetrically spaced on both sides relative to the central vertical axis of the wagon at distances that ensure the coincidence of the axes of the discharge-loading composition of the wagons and the discharge-loading equipment of the terminals.

The disadvantage of this tank car is the large value of the coefficient of material consumption of the car (container coefficient). This is because in order to ensure that the composition of such wagons and the loading and unloading equipment of the terminals coincide, the length of the car along the clutch axes of automatic couplers should be about 24 meters, which is associated with the standard step of the loading and unloading equipment of the terminals, which is about 12 meters. With such a length of the tank car, the permissible overall space of the train is not fully used, the weight of the frame and the boiler, taking into account their length, are overestimated, and the load capacity is correspondingly reduced, which leads to a large value of the coefficient of material consumption of the car (container coefficient), defined as the mass ratio wagon containers to its carrying capacity and component for the indicated tank wagon length of about 0.97.

The design of this tank car is the closest technical solution of the invention and is selected as a prototype.

The problem to which the invention is directed, is to increase the technical and economic indicators of the tank car.

The technical result achieved by the implementation of the invention is to reduce the coefficient of material consumption of the design of the tank car (container coefficient) with a greater degree of use of the permissible overall space of the train, which improves the technical and economic indicators of the tank car, as well as to reduce the time for loading / unloading tank wagons by maintaining the order of discharge and loading of cargo at the unloading and loading terminals with a standard step for placing the unloading ivnogo equipment, is about 12 meters, was carried out without tripping the composition of tank-wagons.

The technical result is achieved by changing the design and linear dimensions of the tank car.

The claimed technical result is achieved due to the fact that the tank car contains a boiler made in the form of a tank consisting of a shell and two bottoms, and mounted on a frame or two semi-frames based on two carts forming the undercarriage of the tank car, while the car -the tank is equipped with two automatic couplers and brake equipment, and the boiler is equipped with one set of drain and bulk valves located in the end of the shell at a distance of 5000 to 7000 mm from the coupling axis of the coupler, and ling tank wagon along coupler automatic couplers is in the range of from 17830 to 18230 mm.

In addition, the boiler shell is equipped with one manhole, as well as one set of safety and control valves.

In addition, the manhole is closed by a lid, on which drain and control valves are placed.

In addition, a set of discharge and / or safety and / or control valves is located at the level of the surface of the shell or is buried inside it, or raised above its surface.

The proposed placement of the drain-and-fill fittings on the boiler at a distance of 5000 to 7000 mm from the coupling axis of the coupler with the length of the tank car along the coupling axes of couplers, which is in the range from 17830 to 18230 mm and is one and a half times the standard step of the terminal-loading equipment , which is about 12 meters, makes it possible to combine the set of drainage and loading fittings for each tank car, when they are included in the composition of cars, with the discharge equipment of the terminals without disengaging the abandonment of tank wagons, which reduces the time for discharge and loading of cargo due to the absence of the need for additional shunting to unhook the composition of such tank wagons submitted for discharge or loading. At the same time, the reduced length of the tank car along the coupling axles of automatic couplers and the more rational use of the permissible overall space of the train makes it possible to reduce the coefficient of material consumption of the tank car (container coefficient) to a value from 0.69 to 0.71.

Also, the technical result is achieved due to the fact that the composition of tank cars includes at least two tank cars, each of which contains a boiler, made in the form of a tank consisting of a shell and two bottoms, and mounted on a frame or two semi-frames, based on two trolleys forming the undercarriage of the tank car, each tank car equipped with two automatic couplers and brake equipment, while the boiler of each tank car is equipped with one set of discharge valves in the end part of the shell at a distance of 5000 to 7000 mm from the coupling axis of the coupler, and the length of each tank car along the coupling axes of the coupler is in the range from 17830 to 18230 mm, with at least one pair of adjacent tank cars composition with orientation to each other by the end parts of the shell, on which sets of drain and bulk valves are placed, or opposite end parts.

When forming the composition of tank cars with the cars oriented to each other by the end parts of the shells on which the sets of drain and tank fittings or opposite end parts are placed, the combination of the set of drain and tank fittings of each tank car with the drain and tank equipment of the terminals is provided without disengaging the composition of the cars - tanks, which reduces the time for discharge or loading of goods due to the lack of the need for additional shunting.
