Definitions

  • the technical solution relates to the mechanism for lifting of the boarding plates of railway wagons designed for transportation of cars.
  • the mechanism enables loading and unloading of cars with small ground clearance without a risk of collision between the chassis and overhangs of cars and parts of wagon deck.
  • a railway wagon is described with a frame, which is created as a wagon platform.
  • a movable platform is mounted with connecting elements for connecting of the wagon with some other wagon, whereby the platform is rotary mounted at the frame end so that the platform is movable between the upper position and the lower position under the wagon floor. It is arranged so that in the lower position the connecting element is parallel with horizontal, or basically horizontal, plane.
  • a wagon that contains portable platforms for the manual manipulation with positioning projections for connecting of the wagon end.
  • the platforms projects above the buffers in order to connect the platform at the wagon end or some other end freight wagon.
  • the platforms are located slightly higher than the wagon floor and close to the container floor. The platform is fitted in the suspended attachment at the wagon end.
  • the bearing platform is located between two adjacent freight wagons that stand one after another, and that are equipped, on their bottom side, with supporting bearings located above the buffer bearings, or they have the bearing sleeves, which interferes with the individual compensatory bush.
  • This equipment provides a firm attachment of the loading platform between the two adjacent freight wagons so that it is possible to travel during loading or unloading operations.
  • the bearings have the guiding plates on the ends heading to the lower side of the loading platform, which interfere with the sliding guiding elements attached to the platform.
  • US2003110975 A1 published on 2003-06-19 , a wagon is described, the wagon having a loading platform, in which the ramp control mechanism for the rolling stock has the first cylinder, the second cylinder and the clutch for reaching the movement into the lifted position.
  • the first double-acting cylinder makes the second double-acting to move the arm and the coupling to the lowered position, when the first cylinder moves the ramp to the opened position.
  • the first cylinder makes the second cylinder to move the arm and the lifting device moves it to the lifted position when the first cylinder moves the ramp to the closed position.
  • the device is used for loading and unloading of cargo, e.g. semi-trailer from the train.
  • the mechanism reduces impacts of the ramp. It reduces the operating pressure necessary for lifting and lowering of the ramp, by which it reduced consumption of pressed air for one operation cycle.
  • the document GB 716260 A1 describes a loading platform of which a portion is pivotally supported on props for movement between a lower platform loading position and an upper position in which vehicles can be run off on to the upper floor.
  • the platform is raised and lowered by a winch and cables, and is held in its raised position by catches actuated by handles.
  • the mechanism contains two direct drives and set of levers with stripes equipped with travelling pulleys.
  • the direct drives push away the stripes with the travelling pulleys, and thus they cause change of the position of the set of levers, and thus the boarding plate, connected with the set of levers, is lifted.
  • It consists of the direct drives connected with the stripes equipped with the travelling pulleys.
  • Sets of levers are rotary attached on the stripes, these levers support the boarding plate.
  • the mechanism for lifting of the boarding plate 4 of the wagon for transportation of cars contains at least two direct drives 1, which are connected to the input shaft 5.
  • the direct drives 1 are connected to the travelling pulleys through the stripes 2.
  • the stripes 2 with the travelling pulleys are rotary connected with the set of levers 3.
  • the sets of levers 3 are attached to the boarding plate 4.
  • the direct drives 1 push away the stripes 2 with the travelling pulleys, and thus they initiate change of position of the sets of levers 3, and thus the boarding plate 4, connected to the set of levers 3, is lifted.
  • the stripes 2 with the travelling pulleys are pushed away or pulled in, and thus an inclination of the set of the levers 3 is changed, and thus height of the boarding plate 4 is adjusted.
  • the mechanism for lifting of the wagon boarding plate is suitable for railway wagons designed for transportation of cars.
  • the mechanism enables loading and unloading of cars with small ground clearance without a risk of collision of chassis and car overhangs with parts of the wagon platform.
  • the mechanism consisting of small number of parts is suitable also for wagons, which have only limited areas for placing of mechanisms for control of the boarding plate.
