[0001] The present disclosure relates to a tube assembly for a transport system and a method of constructing the same, which is applied to a transport system that moves a vehicle under low pressure conditions and provides a driving path for the vehicle.

[0002] Recently, transport systems designed to allow vehicles to travel at high speeds under low-pressure conditions are emerging.

[0046] The operating principle and embodiments of the present invention will be described below with reference to the attached drawings.

[0047] FIG. 1 shows a tube assembly for a transport system according to one embodiment, and FIG. 2 shows an exploded view of a tube assembly for a transport system.

[0048] As illustrated in FIGS. 1 and 2, a tube assembly for a transport system (hereinafter, tube assembly) (1) is intended to provide a driving path for a vehicle traveling under pressure conditions lower than atmospheric pressure, and may include a plurality of tubes (10) forming a driving space (1a) of the vehicle and a connecting part (20) connecting the tubes (10).

[0049] With multiple tubes (10) connected to each other, the driving spaces (1a) inside the tubes (10) can be connected to each other to form a driving path for the vehicle.

[0050] A plurality of tubes (10) are each provided to have a certain length and can be continuously connected through a connecting part (20) to form a tube assembly (1).

[0051] A guide rail is installed inside the tube assembly (1), and the vehicle can travel at ultra-high speed along the travel path while magnetically levitated from the guide rail by the magnetic force formed between it and the guide rail.

[0052] Here, high speed may refer to a speed of 300 km / h or more or 700 km / h or more, but is not limited thereto.

[0053] In a transportation system, a magnetic levitation method may be applied to reduce frictional resistance, which is one of the driving resistances that occurs when a vehicle is driven. In the internal space of the tube assembly (1), the attractive and repulsive forces of the magnetic field are periodically and precisely converted to maintain a constant distance between the guide rail and the vehicle, thereby allowing the vehicle to maintain a magnetically levitating state.

[0054] The internal space of the tube assembly (1) can be maintained at a low pressure state to reduce air resistance when the vehicle is in motion.

[0055] The pressure inside the tube assembly (1) can be a pressure close to a vacuum. When the pressure outside the tube assembly (1) is 1 atm (about 101 kPa, 1 bar) of atmospheric pressure, the pressure inside the tube assembly (1) can be less than 10 kPa (about 0.1 bar).

[0056] The internal pressure of the tube assembly (1) is not limited to this. The internal pressure of the tube assembly (1) may be 1 kPa (0.01 bar or 10 mbar), 500 Pa (5 mbar), 200 Pa (2 mbar), or 100 Pa (1 mbar), and may also include cases with lower pressures.

[0057] In the following description, the internal pressure of the tube assembly (1) will be described based on approximately 100 Pa (1 mbar), which is 0.001 atm, but the interior of the tube assembly (1) can be provided within a range of various pressures including the aforementioned pressure values ​​within a range relatively lower than atmospheric pressure.

[0058] In a transportation system, while a system that levitates and propels a vehicle electromagnetically or mechanically is important, it is also important to implement a tube assembly (1) to maintain a vacuum state or a state equivalent to a vacuum of 0.001 atm or less in the infrastructure, which accounts for more than 50% of the initial investment cost.

[0059] Accordingly, the tube assembly (1) can be made lighter by reducing the thickness of the segmented panels (11) constituting the tube (10), and the rigidity corresponding to the reduced thickness of the segmented panels (11) can be supplemented through the binding part (12) and the restraining ring (30). As a result, the tube assembly (1) can solve the problem of reduced strength due to weight reduction.

[0060] In addition, since the tube assembly (1) can be lightweight while stably securing strength, there is no concern that the weight will increase excessively in response to the expansion of the internal cross-sectional area forming the driving path of the vehicle.

[0061] In other words, while the diameter of circular steel pipes used to construct conventional tubes generally rarely exceeds 2m, circular steel pipes used as tubes for passenger or cargo hyperloops can have diameters reaching 4 to 5m. When such large-diameter circular steel pipes must resist external atmospheric pressure due to an internal vacuum rather than internal pressure, the thickness of the pipe must be relatively thicker than when internal pressure is applied in order to prevent local buckling caused by increased compressive stress.

[0062] In contrast, the tube assembly (1) according to the present embodiment can prevent local buckling of the tube (10) due to increased compressive stress through the reinforcing action of the binding part (12) and the restraining ring (30) without excessively increasing the thickness of the segmented panel (11) constituting the tube (10) when the internal cross-sectional area of ​​the tube (10) providing the driving space of the driving body is expanded. Therefore, the tube assembly (1) does not have to worry about excessive weight increase in response to the expansion of the internal cross-sectional area.

[0063] FIG. 3 shows a cross-sectional view along the dotted line AA of FIG. 1, and FIG. 4 shows an enlarged view of part B of FIG. 3. FIG. 5 also shows in detail the structure of a segmented panel constituting a tube in a tube assembly for a transport system according to one embodiment, and FIG. 6 shows an enlarged view of part C of FIG. 5.

[0064] As illustrated in FIGS. 3 to 6, the binding portion (12) can bind the segmented panels (11) together by a fitting method. The binding portion (12) can bind the segmented panels (11) together by a fitting groove (12a) that is coupled to the circumferential end of one segmented panel (11) in the longitudinal direction of the segmented panel (11) and into which the circumferential end of the other segmented panel is fitted. The tube (10), in which a plurality of segmented panels (11) are fitted together by the binding portion (12), can be manufactured in a segmented form through the segmented panels (11) while also being easy to assemble.

[0065] The binding portion (12) may include a first binding panel (13) coupled along the longitudinal direction of the segment panel (11) to the inner surface of the circumferential side end of the one-side segment panel (11) to support the inner surface of the circumferential side end of the other-side segment panel (11), and a second binding panel (14) coupled along the longitudinal direction of the segment panel (11) to the outer surface of the circumferential side end of the one-side segment panel (11) to support the outer surface of the circumferential side end of the other-side segment panel (11). At this time, the binding groove (12a) may be formed between the first binding panel (13) and the second binding panel (14) and the one-side segment panel (11) so that the circumferential side end of the other-side segment panel (11) is fitted.

[0066] The binding member (12) configured in this way can reinforce the tube (10) in the thickness direction of the tube (10) between the segment panels (11) through the first binding member (13) and the second binding member (14).

[0067] The first binding member (13) and the second binding member (14) can be welded to the inner end and outer end of the segment panel (11), respectively. At this time, the connection between the binding member and the panel surface of the segment panel (11) can be plug welded, and the connection between the end of the binding member and the segment panel (11) can be fillet welded. At this time, the plug welded portion can become the first welded portion (15), and the fillet welded portion can become the second welded portion (16).

[0068] Additionally, each segment panel (11) may be provided with a reinforcing rib (17) extending from the inner surface toward the driving space. This reinforcing rib (17) can support and reinforce the inner surface of the segment panel (11) along the circumferential direction of the tube.

[0069] The reinforcing rib (17) that reinforces the inner surface of the segment panel (11) in the circumferential direction of the tube (10) can increase the compressive strength of the tube (10) according to the compressive load of atmospheric pressure by suppressing the inward deformation of the circumference of the segment panel (11) due to the compressive force caused by external atmospheric pressure.

[0070] Therefore, the segment panel (11) can effectively resist atmospheric pressure even without being formed with an excessively thick thickness.

[0071] In each segment panel (11), a plurality of reinforcing ribs (17) may be arranged spaced apart from each other at a predetermined interval in a direction intersecting the extension direction of the reinforcing ribs (17). Here, the direction intersecting the extension direction of the reinforcing ribs (17) may be the longitudinal direction of the tube (10). Therefore, the reinforcing action of the segment panel (11) by the reinforcing ribs (17) can be applied evenly to the segment panel (11) along the longitudinal direction of the tube (10).

[0072] These reinforcing ribs (17) can be joined to the segmented panel (11) by means of welding, adhesive, or a joining method using a fastening device.

[0073] In this way, multiple segmented panels (11) are connected by a connecting part (12), and the assembled tubes (10) are connected to each other through a restraining ring (30) that forms a connecting part (20) to form a tube assembly (1).

[0074] FIG. 7 illustrates a state in which a restraining ring is interposed between tubes in a tube assembly for a transport system according to one embodiment, and FIG. 8 and 9 illustrate an exploded view of the restraining ring and an enlarged structure of the restraining ring in a tube assembly for a transport system according to one embodiment. FIG. 10 illustrates a coupling structure between a tube and a restraining ring, and FIG. 11 illustrates a coupling cross-section between a tube and a restraining ring.

[0075] As illustrated in FIGS. 7 to 11, the restraining ring (30) is interposed between tubes by having restraining grooves (31) on each side, and the tubes (10) on both sides of the restraining ring (30) can each be restrained by having one end in the longitudinal direction fitted into the restraining groove (31). The circumference of the end of the tube (10), which is connected between the segmented panels (11) by the binding part (12), can be fitted into the restraining groove (31) and restrained. In addition, the circumference of one end of the tube (10) can be restrained by being fitted into the restraining groove (31) so that the inner surface and the outer surface are in close contact. Accordingly, the restraining ring (30) can increase the strength reinforcement effect of the tube (10) by the binding part (12) by reinforcing the circumference of the end of the tube (10) in the thickness direction, and suppress the decrease in strength of the tube due to the reduction in thickness of the segmented panel (11).

[0076] Additionally, the restraining ring (30) can ensure that loads applied from the outside are evenly distributed to the multiple segmented panels (11). The action of the restraining ring (30) can prevent stress from concentrating on specific parts of the tube (10), thereby improving the structural stability of the entire tube (10).

[0077] The restraint groove (31) may include a first restraint section (31a) in which the area of ​​the binding part (12) is restrained, and a second restraint section (31b) in which the area between the binding parts (12) is restrained. These first restraint section (31a) and second restraint section (31b) are alternately arranged along the circumferential direction of the restraint ring (30).

[0078] The first restraint section (31a) of the restraint groove (31) may be formed to be thicker in the radial direction than the second restraint section (31b). This takes into account the thickness of the first binding panel (13) and the second binding panel (14) of the binding part (12) and the width of the binding groove (31).

[0079] The restraint ring (30) may include an inner flange (32) forming an inner surface, an outer flange (33) forming an outer surface, a web (34) connecting them radially, and a pair of intermediate flanges (35) each connected to both sides of the web (34). A restraint groove (31) may be formed between each intermediate flange (35) and the inner flange (32) on both sides relative to the web (34). At this time, a circumferential curve may be formed between the intermediate flange (35) and the inner flange (32) so that the first restraint section (31a) is formed radially thicker than the second restraint section (31b). Through this curved structure, the area of ​​the binding part (12) and the area between the binding parts (12) may be fitted and restrained in the restraint ring (30).

[0080] For reference, in FIG. 10, a is a view of the main part of the tube (10) as seen from the restraining ring (30), b is a view of the main part of the restraining ring (30) as seen from the tube (10), and c is a cross-sectional structure of the tube (10) being restrained by the restraining ring (30).

[0081] The inner flange (32) and the outer flange (33) of the restraining ring (30) may be provided to protrude on both sides along the thickness direction of the web (34) from the surface of the web (34). Thus, the strength of the restraining ring (30) in the thickness direction of the web (34) is reinforced through the inner flange (32) and the outer flange (33), thereby ensuring the connection strength between the tubes connected through the restraining ring.

[0082] In the structure of such a restraining ring (30), the inner flange (32) resists the load acting on the inside of the tube (10) by vacuum pressure, and the outer flange (33) resists the load acting on the outside of the tube (10), thereby allowing the shape of the restraining ring (30) to be maintained stably.

[0083] Accordingly, the restraining ring (30) can firmly restrain the circumference of the ends of the tubes (10) arranged on both sides, thereby reinforcing the strength of the tube assembly (1) at the connection point between the tubes (10). Through this, even if weight reduction is achieved due to the reduction in thickness of the segment panel (11), the tube assembly (1) can secure sufficient strength. Consequently, the restraining ring (30) can contribute to enabling weight reduction of the tube assembly (1) while stably maintaining a near-vacuum state inside the tube assembly (1).

[0084] The connecting portion (20) may further include a connecting member (40) that is coupled to the outer surface of the inner end of the tube (10) in the longitudinal direction. A plurality of connecting members (40) may be coupled to the outer surface of each segment panel (11) and arranged along the circumference of the end of the tube (10) in the longitudinal direction. Additionally, a fastening member (50) may be fastened between the connecting members (40) and the restraining ring (30). The connecting members (40) may be fastened to the web (34) between the middle flange (35) and the outer flange (33) of the restraining ring (30) by the fastening member (50). Thus, the restraining ring (30) can be more firmly fixed to each tube (10) while connecting the two tubes (10).

[0085] FIG. 12 illustrates a modified example of a restraining ring in a tube assembly for a transport system according to one embodiment.

[0086] As illustrated in FIG. 12, a support (36) may be extended and formed on the lower part of the outer flange (33) of the restraining ring (30). The support (36) is intended to support the tube assembly (1) on the installation surface, and the support (36) may be formed integrally with the restraining ring (30) to stably transfer the load of the tube assembly (1) to the installation surface. The restraining ring (30) with the support (36) integrated therein can contribute to simplifying the structure of the tube assembly (1) and improving the constructability of the tube assembly (1) by eliminating the need for a separate part to support the tube assembly (1) on the installation surface.

[0087] Also, FIG. 13 illustrates a modified example of a tube assembly according to one embodiment. As shown in FIG. 13, a reinforcing plate (60) may be attached to the upper portion of each of the plurality of tubes (10) to reinforce the strength of the tube assembly (1) against vertical loads.

[0088] The reinforcing plate (60) on the upper part of the tube (10) can prevent the cross-section of the tube (10) from deforming due to external loads acting in the vertical direction, such as the self-weight of the tube (10), snow load, and wind load. In particular, the reinforcing plate (60) effectively suppresses the local deformation or buckling of the upper part of the cross-section of the tube (10) due to vertical loads, thereby ensuring stable airtightness necessary for maintaining a near-vacuum state of the tube assembly (1).

[0089] The tube assembly (1) configured in this way can be made approximately 14% lighter compared to a tube made of a single circular steel pipe. This was confirmed through an experiment comparing the weight of the tube of the tube assembly (1), which has almost the same strength and length as the circular steel pipe, with that of the circular steel pipe. As a result of the experiment, it was confirmed that a circular steel pipe with a diameter of 4.0 m, a thickness of 30 mm, and a length of 16 m has a weight of approximately 47 tons. And in the case of the tube (10) of the tube assembly (1), which has almost the same diameter and length as the circular steel pipe, it was confirmed that it has an average thickness of approximately 16 mm and a total weight of approximately 40 tons.

[0090] In addition, the tube assembly (1) can be transported to the construction site in a pre-assembly state of the segmented panels (11) and restraining ring (30) to reduce the transport volume during construction. Therefore, compared to a conventional tube assembly made of a single steel pipe, the tube assembly (1) according to this embodiment can reduce the risk of difficulties in transporting due to excessive volume or violation of regulations during the transport process for construction.

[0091] In addition, a tube assembly (1) in which the tube (10) is divided into multiple segmented panels (11) can contribute to increasing the utilization of steel panels with a relatively narrow width. In the case of this embodiment, the tube (10) is provided in an 8-segmental manner through 8 segmented panels (11), and accordingly, the width of the segmented panels (11) can be designed to be approximately within 1,800 mm. Therefore, when producing a tube assembly (1) in which the tube (10) is divided, the segmented panels can be constructed using domestic steel panels produced with a width of approximately within 2,000 mm, thereby ensuring a stable supply of raw materials.
