Description
Technical Field
The present invention relates to the field of transportation and, more particularly, to a chord-type above ground integrated transportation system having a transportation infrastructure that provides rapid freight and passenger transport.
Background
Rail structures [1] of You Nici-based, chord-based rail-based, overpass-based transportation systems are known, for example You Nici-based transportation systems, comprising at least one rail cable fastened to a support in the form of a prestressed load-bearing member (chord) mounted in a body that engages a working surface for vehicle movement. In such a transport system, the chordal rail cords form span sections of a monorail or multitrack track structure within the span between adjacent supports. In order to compensate for the natural sagging of the load bearing members of the guide rail cable within the span between adjacent supports, this type of track structure uses inserts (shims) with variable heights that increase towards the middle of the span, but this complicates the process of manufacturing and installing the guide rail cable under field conditions and does not achieve the effect of flatness and "velvet-like smooth track" of the track structure.
The known chordal transportation system of You Nici base [2] comprises at least one main cable fastened to the foundation at different heights and interconnected within the span between adjacent supports and comprising at least one secondary cable in the form of a prestressed load-bearing member and housed in a body engaging a rolling surface for a vehicle, the at least one secondary cable having a prestressed load-bearing member. The primary cable is connected to the secondary cable by a system of support elements of various heights realized in the form of suspensions and/or struts and arranged at spaced intervals along the span between adjacent supports. In the spacing between two adjacent supports, the rolling surface engaged with the main body of the main rope is positioned with an overrun that increases toward the middle of the span above a straight line passing through each point of the surface in the connection point of the main rope with the adjacent support.
In addition, the rolling surface engaging with the main body of the main rope may be provided on a thickness-variable lining mounted inside or outside the main body of the main rope, between the rolling surface and the carrier member, at the spacing between adjacent support elements or/and within the span between adjacent supports, wherein the main body of the main rope may be integrally formed with the thickness-variable lining.
The choice of the ratio of the spacing between the support elements ensures that the interaction of such a vehicle with the track structure will be maintained during which the stress state of the main cable will remain optimal in each particular spacing.
The known transport system provides sufficient carrying capacity and rigidity of the chordal rail structure, but it is not high-tech and complicates the process of manufacturing guide rail cables at heights up to tens of meters and hundreds of meters under field conditions, and also fails to achieve the flatness of the rail structure and the effect of a "velvet-like smooth rail".
The known You Nici-based [3] transport system, which is considered as a prototype, comprises at least one rail structure in the form of an extended body tensioned over the foundation in the span between the supports, which forms a guideway rail with rolling surfaces on which the vehicle is mounted. The body of such a track structure is made hollow and fitted with a pre-stressed extension load-bearing element positioned therein, beside which a hardened material distributed in the cavity space is poured. The prestress extending load bearing members are positioned within the body in such a way that their position level can vary within the height limits of the interior space of the body along the span between the supports, decreasing toward the middle of the span and increasing toward the two directions of the supports forming the span. By hardened material is meant a material based on a polymer binder, composite material and/or cement mixture, whereas the extended load-bearing element of the structure is made of: filaments, and/or rods, and/or stranded or non-stranded ropes, and/or wires, strips, strands, ribbons, tubes, and/or different combinations of variations of the above high strength materials.
The rail cables in the known transport systems are formed by chordal rails tensioned between anchor supports, which are characterized in common by the presence of an extension body which engages the rolling surface and in which a prestressed longitudinal load-bearing member is enclosed. The working basis of the known transport system is that the rolling surface, which engages with the body of the guide rail cable, forms a track for supporting the wheels of the vehicle, the movement of which can be performed by means of any known type of drive.
Furthermore, in the guide rail cable structure and the entire rail structure of the known transport system, the end anchor that receives the maximum load from the load bearing member of the guide rail cable has a higher material strength and cost. Furthermore, such a transportation system does not provide the required track stiffness and flatness, which does not allow for smooth and light flexibility of running of the vehicle throughout the track structure in an uninterrupted traffic manner during its running.
The core of the invention is to realize the following engineering tasks:
-load is relieved due to the redistribution of stresses in the anchor supports of the chord transportation system;
-improving the reliability of the transport system;
-stabilizing the longitudinal flatness, ensuring the vertical working flatness of the rolling surface of the guide rail cable over its entire length, with the effect of a "velvet-like smooth track".
Disclosure of Invention
The technical task and the desired objects of the invention are achieved by using a You Nici-based chord-type transport system comprising end supports and intermediate supports mounted on a foundation, and at least one guide rail cable stretched in the span between them, which guide rail cable comprises a plurality of prestressed load-bearing elements tensioned between the supports, which prestressed load-bearing elements are incorporated in at least one load-bearing member, which load-bearing member is coupled with a rolling surface for the movement of the vehicle, whereby half of the plurality of load-bearing elements are rigidly fixed in the longitudinal direction in a fastening unit located on the intermediate support, and the rest of the plurality of load-bearing elements are connected to the intermediate support in a manner that the movement in the longitudinal direction is not limited.
A solution to the given problem is also ensured if up to one third of the plurality of carrier elements are rigidly fixed in the longitudinal direction in the fastening units located on the intermediate support.
The technical object is also achieved if up to one tenth of the plurality of carrier elements are rigidly fixed in the longitudinal direction in a fastening unit located on the intermediate support.
This technical aim is also achieved by the fact that the carrier member has a body and a carrier element located in the body.
This is also achieved in that the space within the body of the carrier member is filled with a hardening mixture.
Solutions for the given task are also possible if the carrier member is implemented in a non-body embodiment.
The fact that the fastening unit represents an anchor also ensures the achievement of this result.
A solution to the setup task is also possible in case the anchor is configured to connect a pre-stressed carrying element.
The result can also be achieved by the following facts: the joints of the carrier elements are located on the intermediate support in the fastening unit.
The fact that the intermediate support comprising the fastening unit is equipped with elements that enhance its stability also ensures the achievement of the above-mentioned results.

Detailed Description
The essence of the claimed invention is presented in further detail.
The You Nici-based chord transport system (see fig. 1) as claimed comprises end supports 2 and intermediate supports 3 mounted on a foundation 1.
Depending on the nature of the foundation 1, the installation site and the functional set, the end supports 2 and the intermediate supports 3 may have different designs, for example in the form of: towers, capped posts (not shown), steel and reinforced concrete columns and frame constructions and structures (not shown) equipped with, for example, passenger and/or freight stations, other functional structures.
In the span L between the supports, at least one guide rail cable 4 is tensioned, the guide rail cable 4 comprising a plurality of prestress-carrying elements 5 tensioned between the supports and integrated in at least one carrying member 6 (see fig. 2 and 3).
The end support 2 is an anchor support, the ends of the prestress-carrying elements 5 of the guide rail cable 4 being fixed to the end support 2 by means of anchors.
The intermediate support 3 represents an anchor support, by means of which the end of the prestress-carrying element 5 of the guide rail cable 4 is fixed to the intermediate support 3. Meanwhile, the claimed chord transportation system may comprise an intermediate support 3 that is not an anchor support.
In some cases, where the capacity to erect the complete end support 2 is limited, for example in urban conditions and on soft soil, it is advisable to redistribute a portion of the tension of the load bearing element 5 to the intermediate anchor support 3.
In this case, some of the plurality of load-bearing elements are rigidly fixed (for example by anchoring) in a fastening unit on the intermediate anchoring support 3. At the same time, the remaining carrier elements 5 of the guide rail cable 4 remain unfixed on the intermediate supports 3 and are connected to these in an unrestricted manner in terms of movement in the longitudinal direction. These intermediate supports 3 act partly as intermediate anchor supports and participate in the redistribution of the load forces on the end (anchor) supports 2. Thus, the stability of the end support 2 with respect to longitudinal tension is increased.
As a carrier member 6, the cross-sectional schematic of the main body embodiment of which is shown in fig. 2 and 3, the carrier element 5 can be used generally in the following form: stranded and/or non-stranded ropes, cables, belts, strips, wires, strands, stiffeners, high strength steel wires, tubes made of any high strength material, or other elongated load bearing elements, and assembled into one and/or several bundles.
The carrier member 6 is connected to the rolling surface by means of a body 8 for movement of the vehicle 7.
Wheeled vehicle 7 (passenger and/or freight, and/or common to passenger and freight) may be mounted on wheels on rolling surface a of load bearing member 6 of guide rail cable 4 as part of a You Nici-based chordal transportation system, a cross-sectional view of an embodiment of which is schematically shown in fig. 2; or the wheeled vehicle 7 is suspended from below on the rolling surface a of the carrier member 6 of the guide rail cable 4, fig. 3 schematically showing a cross-sectional view thereof. Meanwhile, the movement of the vehicle 7 may be achieved by any known type of driver.
It will be obvious to a person skilled in the art that the concept of the invention allows various combinations of embodiments of both the carrier member 6 and the guide rail cable 4 to be applied as a whole, depending on design options and desired technical parameters. The guide rail cable 4 may be a single rail or may be an element of a multi-rail track structure, for example, or one of the chords (or chord segments) of a truss construction of a track structure of a chord transportation system, or a cable/wire assembly (not shown).
In some cases of practical implementation of the proposed transport system, the carrier member 6 may comprise a body 8 in which the carrier element 5 is placed. Fig. 2 to 5 schematically show an embodiment of the carrying member 6 of the guide rail cable 4 in a variation of the main body of the practical embodiment.
The space inside the body 8 of the carrier member 6 may be filled with a hardening mixture 9.
According to any of the non-limiting variants of the hardening compounds 9, such hardening compounds may use polymer binder composite compositions, cement compounds (see fig. 2, 3 and 4) and/or similar hardening materials, according to design options.
As a result, the load bearing members 6 of the guide rail cable 4 are grouted (concretized) to transfer and redistribute external loads and forces to all pre-stressed load bearing elements 5 of the chordal transportation system, which significantly increases the bending stiffness and reliability of the main body 8 of the load bearing members 6 of the guide rail cable 4 (see fig. 2, 3 and 4).
At the same time, the carrier member 6 of the guide rail cable 4 does not operate as a flexible element, but as a rigid continuous beam.
Another embodiment is a non-body variant of the carrier member 6 of the guide rail cable 4, whereby the vehicle 7 interacts with and runs on a rolling surface a located directly on the surface of the carrier member 6, which carrier member 6 is manufactured, for example, in the form of a rope.
Common to all practical embodiments of the proposed transport system is that up to half of the plurality of carrier elements 5 are rigidly fixed in the longitudinal direction in the fastening units 10 located on the intermediate support 3, while the remaining plurality of carrier elements 5 are connected to the intermediate support 3 in an unrestricted manner of movement in the longitudinal direction.
The fastening units 10 of the load-bearing elements 5 of the load-bearing members 6 (and the guide rail cables 4 as a whole) on the end anchor supports 2 and the intermediate anchor supports 3 represent any known means, similar to those used in suspension bridges and cable-stayed bridges, ropes and prestressed reinforced concrete structures, for fastening (anchoring) the tensioned load-bearing members (steel bars, ropes, high-strength wires, etc.).
In fig. 4 and 6, an embodiment of the fastening unit 10 of the carrier element 5 of the carrier member 6 on the intermediate anchor support 3 is shown. In this embodiment, the fastening unit 10 comprises an anchor 11 positioned on a load-bearing bulkhead 12 (see fig. 5), which is rigidly fixed to the intermediate anchor support 3.
Since any intermediate anchor support 3 has a certain stability margin, it is recommended for material resources to be saved that the axial forces acting between the end anchor support 2 and the intermediate anchor support 3 of the transport system are redistributed by means of the anchors 11 located on the transverse bulkheads 12 of the intermediate anchor support 3, which axial forces create a prestressing of the load-bearing elements 5 of the guide rail cable 4.
Anchoring a portion of the load bearing elements 5 to the intermediate anchoring supports 3 (on the load bearing bulkheads 12, rigidly fixed to these supports) allows the combined tension of the load bearing members 6 to be evenly distributed and transferred to the intermediate anchoring supports 3, ensuring their load relief and improving the stability of the end supports 2 and the reliability of the rail-chord transportation overpass, while reducing the amount and cost of material of the supports and the load bearing members 6 (as a whole together with the load bearing elements 5 and the guide rail cables 4).
As proved by practical experience in the manufacture and operation of the claimed chord transportation system, when up to half of the plurality of carrier elements 5 are rigidly fixed in the longitudinal direction in the fastening units 10 located on the intermediate anchor support 3, a significant reduction of the amount of material and stress in the intermediate anchor support 3 is achieved if the remaining plurality of carrier elements 5 are connected to the intermediate support 3 in an unrestricted manner of movement in the longitudinal direction (see fig. 4).
From the viewpoint of labor intensity and profitability, it is preferable to rigidly fix up to one third of the plurality of carrier elements 5 in the longitudinal direction in the fastening unit 10 located on the intermediate anchor support 3.
From the standpoint of saving material, ensuring the durability of the guide rail cable 4 and the safety of the transport system, it is advisable to rigidly fix up to one tenth of the carrier elements 5 in the longitudinal direction in the fastening units 10 located on the intermediate anchor supports 3.
The described embodiment of the track structure, in particular of the guide rail cable 4, thus ensures that reliability and safety are maintained even in extreme cases when the integrity of the one or more carrier elements 5 is compromised. Increasing the number of carrier elements 5 rigidly fixed in the longitudinal direction in the fastening units 10 located on the intermediate anchor support 3 beyond half of all carrier elements 5 of the carrier member 6 makes it possible to reduce the load of the support more greatly, but at the same time the material consumption and the costs of the intermediate anchor support 3 increase considerably and the efficiency of the construction technique of the overall transport system decreases unreasonably.
Preferably, the anchor 11 on the intermediate anchor support 3 is configured to connect the prestress-carrying element 5. In this case, the durability of the carrier element 5 and the guide rail cable 4 of the carrier member 6 as a whole is improved.
Advantageously, the joints of the carrying elements 5 are arranged on the intermediate anchor supports 3 in the fastening unit 10. This will reduce costs and simplify the assembly process of the transportation system under field conditions.
Advantageously, the intermediate anchoring support 3, including the fastening unit 10, is provided with elements that enhance its stability, such as struts 13 and/or braces 14 (see fig. 1 and 6). In this case, the amount of material and cost of the support is significantly reduced, and the reliability and load carrying capacity of the You Nici base string transport system is significantly improved.
INDUSTRIAL APPLICABILITY
The construction of the chord transportation system proposed by the base You Nici comprises mounting the end supports 2 and the intermediate supports 3 on the foundation 1, fastening at least one guide rail cable 4 in the span L of the end supports and the intermediate supports, and guiding at least one wheeled vehicle 7 along the guide rail cable. In this case, the bearing elements 5 of the bearing members 6 of the guide rail cables 4 are tensioned and anchored on the end anchor supports 2 and the intermediate anchor supports 3, according to design options.
Thus, in the span between the end anchor supports 2 (for example equal to 10000 meters), it is possible to establish from two to ten intermediate anchor supports 3 at the same distance from each other, depending on design options. Thus, during construction and installation of the guide rail cable 4, the intermediate anchor support 3 will withstand 1/2 to 1/10 of the force from the load bearing element 5, since the load bearing element 5 (e.g. the reinforcing rope) has a limited length of not more than 1000-5000 m.
You Nici-based chordal transportation systems operate in the following manner.
The guide rail cable 4 is arranged between the supports in the span L. The prestressing thereof is achieved by tensioning the carrier elements 5 of the carrier member 6 in the longitudinal direction and anchoring them to the respective supports. Thus, on each intermediate anchoring support 3, the load-bearing elements 5 anchored to the support form a tension balance on both sides of the support. Therefore, there is no overturning moment on the intermediate support 3. Furthermore, each intermediate support 3 has a certain stability margin. Thus, the further from the end supports 2, the greater the stability of the intermediate support 3 and its resistance to the overturning moment of the carrying element 5 anchored thereto. This makes it possible to redistribute the forces acting in longitudinal direction, which create a prestress of the load-bearing elements 5 of the load-bearing members 6 of the guide rail cables 4 between the end supports 2 and the intermediate supports 3 of the transport system, in particular when each intermediate support 3 becomes an end support during construction and installation, since it is closed with a part of the load-bearing elements 5 and the tension forces from said load-bearing elements.
In order to increase the reliability and load-bearing capacity of the chord-type transportation system, the intermediate anchor support 3 with the anchor 11 is reinforced and/or provided with struts 13 and/or braces 14, which allows to increase its stability without significantly increasing the amount of material.
This makes it possible to significantly reduce the amount of material and thus the cost of the transport system without deteriorating its speed characteristics due to the load alleviation of the supports and to reduce and redistribute the combined tension of the load bearing members 6 along the guide rail cable 4 between all supports. Thus, the span L between adjacent supports can be increased.
The You Nici-based chord transport system with the described structure allows to create a transport system with high load capacity and improved handling characteristics and ensures a reduced load, reduced material quantity and stress in the end supports 2, increased stiffness and reliability of the guide rail cable 4, remains stable in its longitudinal uniformity and flatness of the rolling surface a and achieves a "velvet-like smooth track" effect with an increase in the span L between the supports.
With the above significant features, the claimed solution is different from the prototype, i.e. meets the inventive criteria.
By examining the patent and scientific literature, it has not been found that any subject matter contains features that distinguish the claimed subject matter from the prototype and that enable the proposed effect, and it is therefore apparent that the claimed invention meets the patentable novelty criteria.
