Definitions

  • the present utility model relates to railway transport, in particular to design of open wagons used for transporting cargo that does not require protection from atmospheric precipitation, i.e. bulk non-powdered cargo, dry bulk cargo, stockpiled cargo and unit load cargo, and to design of covered wagons used for transporting cargo that requires protection from atmospheric precipitation.
  • An example of such wagon is a universal open wagon of 12-9761 model with unloading gates manufactured by the company “Tikhvinsky vagonostroitelny zavod” (Tikhvin Freight Car Building Plant) and designed for transporting cargo that does not require protection from atmospheric precipitation, e.g. bulk non-powdered cargo, dry bulk cargo, stockpiled cargo and unit load cargo.
  • the open wagon of 12-9761 model has a conventional open wagon design and comprises an all-steel body mounted on two carriages, said body comprising a frame, two side walls, two end walls and unloading gates.
  • the open wagon of 12-9761 model is characterized by the following parameters: body volume is 88 m 3 , length over coupler pulling faces is 13920 mm, body length is 12771 mm.
  • the distance between the closest points of mutually facing end walls of the neighboring bodies is about 800-810 mm.
  • the described open wagon is the closest analog for the present utility model.
  • the disadvantage of the described open wagon of 12-9761 model is ineffective usage of space between neighboring open wagons, said space occupied by coupler devices, e.g. automatic couplers, and free of transported cargo. Furthermore, said disadvantage is responsible for low load per unit length of the knoen open wagon, load per unit length defined as ratio of car load per one meter of railway track.
  • the object of the present utility model is to provide an open wagon design providing cargo transportation with maximum-efficiency by improving technical and economic performance of the open wagon.
  • the object is achieved by the disclosed utility model that provides a railway car comprising at least two bodies supported by carriages, each body comprising a frame, two side walls and two end walls, wherein said at least two bodies are sequentially coupled to each other by at least one joint assembly, wherein each body is supported by two carriages, wherein bodies adjacent to each joint assembly are supported by one common carriage, and the distance between the closest points of mutually facing end walls of neighboring bodies of said at least two bodies arranged on a straight track section is less than 800 mm.
  • the technical result achieved by the present utility model lies in increase of useable volume of space between sequentially arranged open wagon bodies.
  • the technical result is achieved by decreasing the distance between end walls of said bodies.
  • the length of a train consisting of the disclosed open wagons is also decreased compared to the length of a freight train consisting of known four-axle open wagons.
  • the overall stowage factor is also increased compared to that of the known four-axle open wagon due to the fact that the disclosed open wagon comprises at least two bodies.
  • the disclosed open wagon is characterized by an increase in load per unit length.
  • the technical result provided by the present utility model lies in decrease in the number of carriages required for transporting the same cargo. Said decrease is achieved by increasing specific volume of the body, which is defined as a ratio of stowage factor to carrying capacity, due to the fact that the disclosed open wagon is an open wagon of a joint type, wherein each open wagon body is supported by two carriages, and bodies adjacent to each joint assembly are supported by one common carriage. Therefore, the disclosed open wagon provides the possibility of a fuller carrying capacity usage when transporting cargo with relatively low specific density.
  • the open wagon according to the present utility model has a reduced mass and a reduced carrying capacity for each part of the open wagon comprising only one body due to the fact that each body is supported by two carriages, while bodies adjacent to each joint assembly are supported by one common carriage, and the stowage factor for each part of the disclosed open wagon is equal to that of the known four-axle car.
  • the hypothetical four-axle car which can be provided with increased frame length compared to that of the known four-axle car, said increased frame length being equal to the overall length of the open wagon according to the present utility model, and the hypothetical four-axle car can thus have a stowage factor equal to that of the disclosed open wagon
  • the distance between center points of neighboring carriages is reduced compared to the distance between center points of neighboring carriages of said hypothetical four-axle car due to the fact that in the disclosed open wagon two bodies are sequentially coupled to each other by means of at least one joint assembly, each body is supported by two carriages, and bodies adjacent to each joint assembly are supported by one common carriage.
  • the cross-sectional area of longitudinal frame bars can be reduced, therefore reducing mass of each frame, and therefore, reducing the mass of each body of the disclosed open wagon, and thus, the empty weight-to-carrying capacity ratio of each body of the disclosed open wagon is reduced, which, in turn, provides lower empty weight-to-carrying capacity ratio of the disclosed open wagon compared to the empty weight-to-carrying capacity ratio of the hypothetical four-axle car with increased frame length.
  • the reduction in manufacturing and operating costs of the open wagon is provided by the possibility of using three carriages for supporting of two bodies, while retaining the same stowage factor for each part of the open wagon comprising only one body, said stowage factor being equal to that of the known four-axle car with identical frame length.
  • said at least one joint assembly is a hinge joint assembly.
  • each of said at least two bodies comprises a roof.
  • a distance between the closest points of mutually facing end walls of neighboring bodies of said at least two bodies arranged on a straight track section is from 150 mm to 800 mm.
  • FIG. 1 shows a schematic side view of an open wagon according to a preferred embodiment of the present utility model.
  • FIG. 1 shows a side view of an open wagon according to a preferred embodiment of the utility model.

  • two other carriages 6 , 8 are positioned near the ends of frames 4 , 5 . The positions of said two carriages 6 , 8 are selected to provide equal vertical load applied by the loaded open wagon to each carriage.
  • the carriages can be carriages of any known type. In case carriages of different types are used in one car, their positions are also selected to provide equal vertical load on each carriage.
  • the open wagon is preferably used for transporting cargo that that does not require protection from atmospheric precipitation, i.e. bulk non-powdered cargo, dry bulk cargo, stockpiled cargo and unit load cargo.
  • each body 1 , 2 of the open wagon comprises two side walls 9 , 10 and two end walls 11 , 12 mounted on frames 4 , 5 in order to limit space occupied by the cargo, and in order to maintain said cargo on frames 4 , 5 .
  • side walls and/or end walls of the open wagon can be made removable or, alternatively, said walls can be welded to the frames.
  • FIG. 1 illustrates a distance (L) between end walls 11 , 12 of neighboring bodies 1 , 2 .
