Description

Technical Field

[0001] The present invention relates to the field of transportation, and in particular to a rail transportation system having a string-type guide rail structure, which can be used to develop single-track and multi-track roads to provide passenger and freight transportation in rough terrain, mountainous areas, deserts, as well as in megacities and offshore parts of transportation routes. Background Art

[0002] Document FR 2 962 960 A1 discloses an overhead device for transporting people in an urban environment. The device has cables that are bent in a curved manner and are spaced apart from each other. The rollers of a slingless vehicle move on the cables. A connecting unit is placed between the rollers and the passenger compartment of the vehicle for positioning the passenger compartment in the longitudinal and transverse directions. The vehicle has a central unit for controlling the jacks in order to compensate for the changes in the height of the rollers caused by the cables during the movement of the vehicle on a curved path.

[0003] A suspension transport system is known which comprises a running rail and a vehicle in the form of a car body. The running rail is made in the form of a double track rail which is located on a longitudinal beam mounted on an inner cantilever of an intermediate support. The system is equipped with a propeller in the form of a bogie having an electric motor mounted thereon and a body on pneumatic stabilizers.

[0004] The disadvantages of this transport system are the increased material capacity of its design due to the very limited load-bearing capacity of the running guide beams, as well as the complexity of transporting the beams of the extended span structure to the installation site, the complexity of assembling them on site in difficult terrain and their limited possibilities for constructing larger spans between adjacent intermediate supports.

[0005] Also known is a guide rail comprising two supporting and longitudinal elements connected by a transverse element, the transverse element being provided with side plates which connect the supporting elements to the longitudinal elements, which are also in the form of plates, wherein a part of the transverse element can be connected to the supporting element and another part to the supporting and longitudinal elements.

[0006] The disadvantage of this solution is that the known transport system has a guideway structure of bulky metal mass design, which requires very small spans between the intermediate supports of the overpass in order to ensure its reliability. Despite the structural rigidity of a track of this profile, an increase in the span between the supports leads (assuming that reliability is maintained) to an excessive increase in the material volume of the guideway structure and to a reduction in its specific load-bearing capacity. In addition, the conditions for transporting and installing the structural elements to the destination (installation) become significantly more complicated.

[0007] A transport system is known that includes a supporting monorail and a transport module, wherein the supporting monorail rests evenly on sleepers in the soil through modules (tetrahedrons on piles), has a starting slide and a terminal reverse ramp, and its transport module is a platform with two compartments, which has a self-centering flywheel-gyroscope on four central double-flange wheels and four lateral supporting rollers, and can mount the body (compartment, box, container) on the platform through brackets for transporting various goods. In another embodiment of this transport system, it includes a suspended monorail and a transport module, wherein the suspended monorail is an I-beam suspended on two longitudinal load-bearing ropes tightened by transverse tie rods through struts along the ribs of the module (tetrahedron), and also has a starting slide and a terminal reverse ramp. In this case, the transport module is suspended.

[0008] The disadvantage of this technical solution is that the transport system has a low specific load-bearing capacity, which is understood to mean the ratio of the effective load weight to the fixed load of the components of its guide rail structure, which is particularly important for flyovers and suspended roads and, in this case, leads to a significant increase in the cost of the transport system, as well as an increase in the complexity of transporting the elements of the running guide rails of the guide rail structure to the installation site and assembling them on site, and limits the possibility of using guide rails of a specified structure to construct large spans between adjacent intermediate supports.

[0009] A general disadvantage of known flyover transport systems is the low specific load-bearing capacity of their guideway structures, which leads to a significant increase in the cost of the entire transport system. Typically, such transport systems provide for the design of guideway structures in the form of heavy and bulky beams of extended span structures, the transportation and installation of which under actual site conditions in complex terrain would be a very time-consuming and expensive technique.

[0010] Moreover, the presence of joints in the guide rails and the thermal deformations of the rails of this transport system will not allow the phenomenon of "velvety smooth" guide rails for vehicles, which means that it is impossible to achieve high speeds and guarantee high reliability of transport on this type of guide rail structure.

[0011] The elaboration and creation of transport systems based on Yunitski's rope-guided structure, based on the use of its longitudinally prestressed load-bearing string members as the main structural elements of the track, stimulated further developments in the construction of transport systems of the suspension and flyover types.

[0012] A transport system is known from Yunitski, which transport system comprises at least one guide rail structure which is tensioned above the foundation in the span between the supports, the guide rail structure being in the form of a load-bearing member enclosed in a body having a rolling surface for the movement of a wheeled vehicle mounted on the guide rail structure. In the above arrangement, the cross-sectional area of ​​the load-bearing member and the track body having the rolling surface is optimized, and the tension of the guide rail structure and the load-bearing member of said structure, the allowable value of the sagging of the guide rail structure between adjacent supports and the height of the supports are well adapted.

[0013] However, known transport systems have excessive material capacity, thus increasing costs, have lower manufacturability, and therefore higher labor intensity.

[0014] A rope transport system of Yunitski is also known, which comprises at least one track rope, tensioned above the foundation, in the span between anchored supports, in the form of a load-bearing part, enclosed in a body with a rolling surface for a self-propelled vehicle. The load-bearing elements of the load-bearing part are thus connected to each other and to the entire body (in the entire volume) by means of a filling aggregate. The supports have transition sections of the guide rails, and the track rope in the span between the supports is made to sag with a certain slope, the transition section of the guide rail on the supports being made with the same slope as the section of the suspended section of the guide rail cooperating with it in the span between the supports.

[0015] The above-mentioned guide rail structure has high material strength and labor, thus increasing the cost and insufficient workability.

[0016] Among the transport systems with track structures associated with suspended roads and flyover roads, the track of the Yunitski transport system is known, which contains a hollow tubular body with a covering head, inside which there is a load-bearing part made of prestressed load-bearing elements, mainly wires and / or ropes, distributed over the cross section of the track, while the walls of the body are closed. Different choices of the distribution of the ropes over the cross section of the track and an optimal ratio of the cross-sectional areas of the track body and the ropes are possible. Therefore, the present system is formed in the form of a spiral surrounding the load-bearing part, and the covering head is fastened to the spiral of the spiral. In addition, the space between the body and the load-bearing part is filled with a filling aggregate. The method for manufacturing such a track of the guide rail structure of Yunitski comprises: the load-bearing part is formed by the load-bearing element and used as a mandrel in the manufacture of the track body, while the track body is manufactured, and the load-bearing part is simultaneously arranged therein by laying a layer wound by high-strength metal wires or belts on the surface of the load-bearing part.

[0017] A transport system with such a track rope guarantees high workability in its manufacture. However, the material strength of the specific guideway structure obtained by the method described is still too great. The transport system of Yunitski, which is accepted as a prototype, is the closest to the claimed invention in terms of technical essence and the results obtained. It comprises at least one track rope, which is tensioned above the foundation in a span between supports in the form of a load-bearing part, which contains a load-bearing element prestressed in the longitudinal direction, which is consolidated into an adhesive layer of the load-bearing part and is enclosed in a hollow body having a rolling surface for the movement of a wheeled self-propelled vehicle mounted on the guideway structure.

[0018] In the above technical method, the track rope is equipped with a hollow body, which serves as a housing for the load-bearing part. Therefore, the hollow body is equipped with a rolling surface for a self-powered wheeled vehicle, and the load-bearing part positioned in the hollow body is made in the form of a load-bearing element prestressed in the longitudinal direction, which is consolidated into the adhesive layer of the load-bearing part. The load-bearing part is connected to the hollow body (in which it is located) by using an adhesive layer. Transport systems with this type of guide rail structure provide a high specific load-bearing capacity, however, the material strength and processability of the track rope design are still not fully optimized.

[0019] It would be advantageous to simplify the design of the track ropes.

[0020] The task underlying the claimed invention is to achieve the following technical objectives:

[0021] - Increase the specific load-bearing capacity of the guide rail structure;

[0022] - simplify the handling of the components of the guide rail structure and its installation in practical conditions;

[0023] -Material strength and labor are reduced while the machinability of guide rail structure manufacturing is improved.

[0024] The solution of this task is ensured by a whole set of unique features of the proposed transport system. Summary of the invention

[0025] The desired technical result and purpose of the present invention are achieved due to the situation in the transport system of Yunitski, which transport system comprises at least one track rope, which is tensioned between anchor supports above a foundation, comprising at least three discrete (isolated) load-bearing elements, which are prestressed in the longitudinal direction and are positioned on the same line in the cross section of the head of the track rope, wherein each discrete load-bearing element comprises a contact surface continuous along the entire length of the track rope, which contact surface is arranged to be able to form a rolling surface of the track rope for a self-powered wheeled vehicle as a whole through all the discrete load-bearing elements, wherein the width S (m) of the track rope is related to the height H (m) of its discrete load-bearing elements by the following ratio:

[0087] More specifically, the essence of the present invention includes the following.

[0088] The transport system claimed by Yunitski (see Figure 1 ) comprises at least one track rope 3 which is tensioned between anchor supports 2 above a foundation 1 .

[0089] Depending on the nature of the foundation 1, the installation location and the functional setting, the anchor support 2 can have various structural designs - in the form of towers, columns with heads, steel and reinforced concrete columns and frame buildings, as well as structures equipped with passenger stations and / or cargo terminals, other functional structures or truss structures (not shown in the figure).

[0090] The track rope 3 comprises at least three discrete load-bearing elements 4 prestressed in the longitudinal direction, which are located on the same line L in the cross section of the track rope 3 (see FIG. Figure 2-6 The discrete load-bearing elements 4 are fixedly placed on the cap-shaped member 5 of the intermediate support 6 by using transverse spacers 7 (see Figure 7-9 ).

[0091] The transverse partitions 7 can have various shapes and materials, for example, they can be implemented as metal plates with shaped transverse grooves, such as Figure 7-9 This ensures the desired distribution of the discrete load-bearing elements 4 on the same line L in the cross section of the track rope 3. The transverse webs 7 are arranged so as to be fixable on the cap 5 of the intermediate support 6.

[0092] The design of the intermediate supports 6 can be different depending on where they are installed. In particular, a cap-shaped member 5 with means for fastening discrete load-bearing elements 4 (the cap-shaped member 5 is installed on a bend in the guide rail, on a linear section of the guide rail, in a mountain range or at the end of the guide rail) (see Figure 1 ) may vary, as the device must fit smoothly with the suspended portion of the track ropes 3 in the span 8 between the intermediate supports 6. In addition, the shape of the caps 5 may be determined by their function as the location of the connection nodes (conversion assemblies) of the transport system (not shown in the figures).

[0093] It is very important that each discrete load-bearing element 4 comprises a contact surface K which is continuous along the entire length of the track rope 3 and a rolling surface N of the track rope 3 for the self-powered wheeled vehicle 9 (see Figure 2-9 ), the rolling surface N is arranged to be formed by all discrete load-bearing elements 4 as a whole (see Figure 10-1 2). Due to the above-mentioned design of the track rope 3, the deformation load generated during the movement of the self-propelled wheeled vehicle 9 is uniformly redistributed on the contact surface K of each discrete load-bearing element 4 tightened between the anchor supports 2, thereby achieving an increase in the specific load-bearing capacity of the guide rail structure. In this case, the contact surface K should be understood as the surface of each discrete load-bearing element 4, wherein when the self-propelled wheeled vehicle 9 moves along the track rope 3 of the guide rail structure, the contact point (contact spot) of the contact pair "wheel-track rope" moves, or in other words, the surface of each discrete load-bearing element 4 (the surface directly receives the contact force of the wheel 10 of the self-propelled wheeled vehicle 9 when the self-propelled wheeled vehicle 9 moves) moves.

[0094] The self-powered wheeled vehicles 9 (passengers and / or cargo and / or cargo and / or passengers) included in the transport system of Yunitski can be implemented in a suspended embodiment (suspended from below on the track ropes 3), such as Figure 1 As shown, and performed in an installation embodiment (not shown in the figure).

[0095] According to any non-limiting embodiment of the proposed transport system, one of the main elements determining the essence of the proposed technical solution is the track rope 3 of the guide rail structure. The distinguishing feature of the track rope 3 according to the proposed technical solution is that it is implemented in the form of at least three discrete load-bearing elements 4 prestressed in the longitudinal direction, each load-bearing element 4 comprising a contact surface K (see Figure 10-1 2), the contact surface K being continuous along the entire length of the track rope 3 and being arranged to form a rolling surface N for the self-powered wheeled vehicle 9 (see Figure 2-9 ), the rolling surface N is formed integrally by all discrete load-bearing elements 4. It is important that the discrete load-bearing elements 4 do not have a single body joining them along the entire length of the track rope 3. Therefore, the track rope 3 is actually made "bodyless" as a unified shell in the traditional ordinary meaning of the concept of body.

[0096] The implementation of the proposed innovative variant of the transport system (with a track rope 3 in the form of discrete load-bearing elements 4, which track rope 3 has no body in the form of a casing) makes it possible to obtain significant advantages compared to the known technical solutions, due to the reduced weight of the track rope 3. In particular, it is ensured that the specific load-bearing capacity of the guide rail structure is increased, while reducing the material and labor intensity, and increasing the manufacturability of its production, for example due to the fact that the track rope 3 of the proposed guide rail structure is delivered to the installation site in the form of blanks of discrete load-bearing elements 4 of various types (in the form of coils and / or coils).

[0097] By this design, each discrete load-bearing element 4 comprises a continuous contact surface K. At the same time, in the proposed transport system, the track ropes 3 have no additional shell in the form of a common body, which is present in prototypes and analogs.

[0098] As shown by experimental tests, in the proposed solution the track rope 3 achieves the minimum permissible operating stiffness and lateral stability, as long as the track rope 3 comprises at least three discrete load-bearing elements 4 which are prestressed in the longitudinal direction.

[0099] Such a design of the track rope 3 also enables an increased safety level of the proposed transport system.

[0100] As a result, the values ​​of geometrical parameters of the track rope 3 and its discrete load-bearing elements 4, their positioning, the values ​​of prestressing of these discrete load-bearing elements 4 in the longitudinal direction and the tensioning force T (N) of the track rope 3 are significantly increased.

[0101] The dimensions of the track rope 3 are chosen such that its width S(m) is related to the height H(m) of its discrete load-bearing elements 4 by the following ratio:

[0102] 3≤S / H≤50(1)

[0103] When the track ropes 3 are manufactured with a width S (m) and the discrete load-bearing elements 4 with a height H (m), whose ratios are within the limits specified in expression (1), the required strength, reliability and geometry of the guide rail structure can be ensured.

[0104] When the ratio (1) is less than 3, the track rope 3 of the proposed transportation system will have lower load-bearing capacity and strength.

[0105] When the ratio (1) is greater than 50, the track rope 3 will not have sufficient stiffness, including twisting, when the self-powered wheeled vehicle 9 moves along it.

[0106] Thus, adjacent discrete load-bearing elements 4 are arranged corresponding to each other (see Figure 2-5 ), where the gap δ(m) is determined by the following relationship:

[0107] 0≤δ / H≤5, (2)

[0108] 0≤δ / H≤2, (3)

[0109] 0≤δ / H≤1(4)

[0110] Ratios (2), (3), and (4) cannot be less than 0 because the gap cannot be negative.

[0111] When adjacent discrete load-bearing elements 4 are arranged so that the gap δ(m) between them exceeds the upper limit value specified in the ratio (2): δ / H≤5, such a gap δ(m) will not enable the track rope 3 to provide the rigidity, load-bearing capacity and safety required by the guide rail structure.

[0112] In a preferred embodiment of the guide rail structure of the proposed transport system, it is preferred that the gap δ (m) separating adjacent discrete load-bearing elements 4 of the track rope 3 does not exceed the upper limit specified in the ratio (3): δ / h≤2, thereby improving the safety of the guide rail structure.

[0113] In the most preferred case of the actual implementation of the guide rail structure of the transport system, adjacent discrete load-bearing elements 4 of the track rope 3 must be arranged accordingly to each other so that the gap δ(m) does not exceed the upper limit value specified in the ratio (4): δ / H≤1, which will ensure the optimal values ​​of the stiffness and load-bearing capacity of the track rope 3 and at the same time have maximum guide rail structural safety.

[0114] Therefore, the track rope 3 is tensioned to a force T (N) determined by the following ratio:

[0115] 10≤T / (Mg+mg)≤200, (5)

[0116] Where: T (N) - tension of track rope;

[0117] M (kg) - the total calculated weight of the self-powered wheeled vehicles simultaneously located on the track ropes in the span between adjacent supports;

[0118] m (kg) - weight of the track rope in the span between adjacent supports;

[0119] g(m / sec 2 )-acceleration due to gravity.

[0120] Reaching the lower limit of the ratio (5) (equal to 10) corresponds to a situation when the track rope 3 is slightly stretched and has a large slack in the span 8 (under its own weight (gravity) and the weight of the 8 self-powered wheeled vehicles 9 located in this span), which drastically deteriorates the performance of the system, in particular the traffic safety. In this case, the stiffness of the discrete load-bearing elements 4 and the track rope 3 as a whole will deteriorate, which is unacceptable.

[0121] When the upper limit of the ratio (5) (equal to 200) is exceeded, the track rope 3 will be tensioned with excessive force at low weight, which will require the use of expensive high-strength materials and lead to deterioration of the technical and economic characteristics of the system.

[0122] In the cross section of the track rope 3, the discrete load-bearing elements 4 are arranged along a straight line L (see Figure 2-6 ), in an alternative embodiment (not shown in the figure) arranged along a curved line (including a dashed line). This arrangement of discrete load-bearing elements 4 ensures that the working strain from the wheels 10 of the self-powered wheeled vehicle 9 is evenly redistributed between the load-bearing elements, thereby increasing reliability and reducing the material strength of the guide rail structure.

[0123] like Figure 5 As shown in FIG. 1 , the wheels 10 of the self-powered vehicle 9 are made into double flanges, which increases the stability of the self-powered wheeled vehicle 9 and the safety of the entire transportation system.

[0124] At the same time, the profile of the tread surface Z of the wheel 10 matches the profile of the rolling surface N of the track rope 3 at the position where the track rope 3 is fastened to the cap-shaped member 5, which also increases the stability of the self-powered wheeled vehicle 9 because the lateral amplitude of the track rope 3 in the span 8 is reduced when the self-powered wheeled vehicle 9 moves along the track rope 3.

[0125] On the support there is a transition section of the guide rail - a cap 5 in the form of a saddle 11, while the track rope 3 in the span 8 between adjacent supports 2 and / or 6 is made to sag with a certain slope. It should be noted that the guide rail transition section on the saddle 11 has the same slope as the hanging section of the guide rail cooperating with it in the span 8 between adjacent supports 2 and / or 6 (see Figure 1 ), which ensures smooth movement of self-powered wheeled vehicles.

[0126] Therefore, in any embodiment of the track rope 3, it is preferred that the transverse partitions 7 are provided with retainers 12 for the lateral displacement of the discrete load-bearing elements 4 (see Figure 7-9 ), which will prevent the discrete load-bearing elements 4 from moving relative to each other and ensure that they are fixed in a predetermined position during operation of the transport system. The retainers 12 for the lateral displacement of the discrete load-bearing elements 4 can be made, for example, in the form of corresponding shaped lugs (wing-shaped extensions) of the transverse partitions 7, or in the form of shaped grooves which, with their sides, surround and fix the relative position of the discrete load-bearing elements 4 of the track rope 3 (see Figure 7-9 ).

[0127] Since the load-bearing element 4 is fastened to the saddle 11 of the cap 5 of the intermediate support 6 by means of transverse partitions 7, which are equipped with retainers 12 for the lateral displacement of the discrete load-bearing element 4, and since the wheels 10 of the self-propelled wheeled vehicle 9 are provided with a tread surface Z corresponding to the profile of the rolling surface N of the track rope 3 at the position where the discrete load-bearing element 4 is fastened to the saddle 11 of the cap 5 by means of transverse partitions 7, this ensures that the specified geometry of the track rope 3 will be maintained and that the movement of the self-propelled wheeled vehicle 9 is stabilized in the entire guide rail structure of the proposed transport system.

[0128] An alternative design of the proposed transport system provides for the discrete load-bearing elements 4 to be interconnected in the span between the intermediate supports 6 by transverse webs 7. This increases the rigidity and safety of the guideway structure.

[0129] In order to optimize the operating parameters of the track rope 3 (due to a special design distribution), it is preferred that the transverse profile of its discrete load-bearing elements 4 is made circular, e.g. Figure 2 and 7 As shown in, or made into an elliptical shape, such as Figure 4 and 7As shown in, or made into a square, as Figure 5 As shown in, or made into a tube shape, such as Figure 6 As shown, or made into a rectangle, such as Figure 8 as shown in .

[0130] Embodiments of the track rope 3 with discrete load-bearing elements 4 having a cross section in the shape of a polygon or rhombus or triangle or trapezoid or other possible known shapes are similar to the above described embodiments and are not shown in the figures.

[0131] According to any embodiment of the present invention, the load-bearing element (whose cross section is in Figure 2-9 ), discrete load-bearing elements 4 ( Figure 2 and 7 ), twisted or untwisted ropes of any solid material (see Figure 3 ), strand, cord or ribbon (see Figure 4 and 9 ), or with or with a rod (see Figure 5 and 8 ) or tube (see Figure 6 ), such as high-strength steel, or glass fiber or Kevlar or polyetheretherketone or graphene, which ensures the reliability, efficiency, economy and processability of using such load-bearing elements.

[0132] It will be appreciated by those skilled in the art that the present invention is capable of using a plurality of rail rope 3 cross-section types based on a design combination, depending on the shape of the discrete load bearing elements 4 contained therein and the combination of positioning (distribution) lines L used in its formation.

[0133] According to the proposed technical solution, by any practical implementation and arrangement of discrete load-bearing elements 4 , the required material saving in the guide rail structure of the entire transport system and the improved manufacturability and stability of the track rope 3 are achieved.

[0134] Taking into account all possible alternatives and non-exclusive combinations, including the above-mentioned variations and design parameters of the discrete load-bearing elements 4 of the track ropes 3, many embodiments of the proposed Yunitski transport system are possible, which generally ensure the installation of supports 2 and 6 with a span 8 directly along the route contour on the foundation 1 according to the design options (see Figure 1 and 13 ). At least one track rope 3, which is tensioned above the base 1, is fastened to the support 6. The track rope 3 is thus made of at least three discrete load-bearing elements 4, which are prestressed in the longitudinal direction by their tensioning and fastening between the anchor 2 supports.

[0135] At the same time, it is important that the track rope 3 is made bodyless and is equipped with discrete (distributed) rolling surfaces N.

[0136] According to the present solution, the desired result is achieved due to the reduced material consumption of the proposed track rope 3 compared to the known solutions. At the same time, the embodiment of the track rope 3 of the structure claimed in the solution provides the required strength of the guide rail structure, because the entire load from the self-powered wheeled vehicle 9 on the track rope is accumulated by its discrete load-bearing elements 4, which are prestressed in the longitudinal direction. In addition, the track rope 3 can be assembled under on-site conditions using high-tech equipment that is delivered directly to the transportation system installation site. At the same time, the component materials (such as wires or cables) can be delivered to the transportation system installation site in a compact form (for example in the form of coils and / or rolls), which helps to reduce material strength, labor, transportation costs, manufacturing and installation costs of the guide rail structure, while improving the manufacturability of the production of such a transportation system.

[0137] Industrial Applicability

[0138] For the various embodiments of the proposed Yunitski transport system, the geometrical parameters of the track rope 3 and the properties of the discrete load-bearing elements 4 forming it, optimized as a result of empirical studies, make it possible to create a guide rail structure of a transport system with specified operating parameters and ensure an increase in its specific load-bearing capacity.

[0139] The proposed Yunitski transport system can be implemented in field conditions at lower costs compared to known structures of guideway structures and is a high-tech solution.

[0140] The view presented above in simplified form represents one possible manufacturing option of a Yunitski transport system according to the proposed technical method.

[0141] The Yunitski transport system of the described structure operates in the following manner.

[0142] When the wheel 10 of the self-powered wheeled vehicle 9 moves along the track rope 3, the track rope 3 receives and adapts the load concentrated on the contact surface K from the wheel 10 of the self-powered wheeled vehicle 9 through its continuous rolling surface N, causing it to deform elastically. The deformation wave moving along the rolling surface N with the wheel 10 of the self-powered wheeled vehicle 9 is uniformly redistributed to the discrete load-bearing elements 4 tightened between the anchor supports 2.

[0143] Due to the "bodyless" design of the track rope 3, through the high manufacturability and reduced number and cost of the components required for its manufacture, according to the combination of all the basic characteristics that determine its advantages, the Yunitski transport system of said structure makes it possible to achieve a significant increase in the specific load-bearing capacity of the guide rail structure and a reduction in the construction costs of the transport roads, including by saving material strength and labor, while improving the manufacturability of its production and simplifying the transportation handling of the components and its installation under real conditions.
