Definitions

  • the present invention relates to the above-ground transport systems of string type with rail track structure related to overpass-type tracks. It can be used in development of both inner-city highways and in construction of intercity and international transport systems.
  • the logical solution to improve the existing track structures are the string transport systems by Yunitski.
  • Linear transport system by Yunitski is known, see RU 2 080 268 C1 , which includes at least one vehicle having a drive unit and guided by wheels on at least one rail containing a head and connected to a prestressed longitudinal element mounted on supports located on foundation.
  • Prestressed longitudinal element of this transport system is made in the form of at least one string connected by gaskets of variable height with head of each rail along the whole length.
  • the rail head is connected to DC or AC electric power source, and the rail is connected to the support by means of electric insulator.
  • Rails in the said transport system are connected to each other by means of transverse strips, which are equipped with electric insulators and dampers.
  • the supports are rigid and movable, whereas the rail track is connected to the movable support by a mechanism of mutual relative longitudinal displacement, including, for example, with use of a rod, and/or a mechanism for adjusting its position relative to the support and foundation, and/or by means of a damper.
  • Transport system by Yunitski which includes at least two pretensioned rail cords in the form of load-bearing members enclosed in bodies (casings) with rolling surfaces mating therewith, for vehicles.
  • Rail cords form two track structures. Loaded and empty vehicles (see RU 2 475 386 C1 ) are installed on rail cords of track structures.
  • both rail cords of each track are interconnected in spans between adjacent supports by means of two-level trussed track structure in the form of zigzag-oriented rod elements, forming triangles with lower and upper rail cords and located on the outer sides of those rail cords, wherein at each level of the track structure, left and right rail cords are connected to each other by cross bulkheads installed in junction units of rod elements and rail cords.
  • a limitation to the wide use of the said transport system is the insufficient rigidity of its track structure, caused by the significant height of the track structure (considering the height of vehicles) relative to the width of its wheel track.
  • the dynamic stability of the track structure in spans between the adjacent supports is also limited.
  • the object of the invention is to solve the following technical tasks:
  • RU 2224064 C1 in the name of the Applicant, discloses a transportation system comprising at least one main line secured on supports and made in form of prestressed power member enclosed in housing with mating rolling surface for running vehicles, and at least one auxiliary line with prestressed power member secured on supports at another level relative to the main line.
  • Main and auxiliary lines are rigidly interconnected over entire span between adjacent supports by means of rod of crisscross orientated rod members whose longitudinal axes form triangles with longitudinal axes of main and auxiliary lines.
  • main and auxiliary lines are arranged equidistantly over entire length of span, and auxiliary line secured under main line is provided with at least one side rolling surface.
  • UA 71059 U discloses an elevated railway transport system that includes an overpass consisting of a series of interconnected elevated frames that rely on vertical supports, and made with box-shaped cross section formed by lateral, upper and lower structural elements of frames.
  • Two supporting tracks are fixed on the structural elements of frame.
  • Transport modules are mounted on rail tracks with possibility of oncoming traffic.
  • Rail interchange systems are provided at the end sections of the overpass.
  • the rail tracks are located on two levels - the lower track is mounted on the lower structural elements of frames.
  • the upper track is mounted above the lower track on the upper structural elements of frames.
  • the systems of rail interchange at the end sections of overpass are made in the form of a beam, which one end is pivotally secured on the support with possibility of turning the beam in the vertical plane of the track secured on the beam, as well as a drive for turning the beam in the position of joining the track of beam with the lower or upper track of elevated frame.
  • JP 2006 096057 discloses a transportation system for a light user's case body.
  • An aerial carriage is hung down by a high-tension thin steel plate hanger having a driving wheel.
  • the technical aims are also achieved provided that the distance R, m, between the junction units of rod elements and rail cords of the lower level of the trussed track structure in each span is made multiple of the distance between the supports.
  • Tackling the set tasks is also ensured by the fact that the assembly connection of the transverse beam with the support is made in the form of a pivot lever.
  • the rail cord is current-carrying with the possibility of connection to a source of electric power of direct or alternating current.
  • the inventive string transport system by Yunitski as shown on Figure 1 , comprises two rail cords of lower 3 level mounted on the foundation 1 between the supports 2 (anchored 2a, resting on intermediate 2b), and two rail cords of upper 4 level of the track structure, arranged above them.
  • Anchor supports 2a may be buildings and structures with specially equipped boarding and loading areas in the form of loading and unloading stations: passenger for passenger routes and cargo for freight routes (not shown on the Figures).
  • Rail cords of the lower 3 and upper 4 levels of the track structure are made (see Figs. 1 and 4 ) in the form of prestressed load-bearing members 5 enclosed in the respective bodies 6 (see Fig. 3 ).

  • the rolling surface 8 may be formed by the surface of the body 6 itself.
  • the body 6 of the rail cord 3 and/or 4 may partially serve the functions of the prestressed load-bearing member 5, if it has also been stressed by tensioning during assembling of the structure.
  • the rail cords of the lower 3 and upper 4 levels with mating therewith rolling surfaces 8 for the wheeled vehicles 9 and, accordingly, the tracks formed by them are made of an innovative modification - prestressed by tensioning in the longitudinal direction, those rail cords are load-bearing rigid beams of the lower and upper chords of the span arrangement (superstructure) of the two-level trussed track structure.
