Description

Tubes for transport systems

[0001] The present disclosure relates to a tube for a transportation system, and more particularly, to a tube for a transportation system that is applied to a transportation system that moves a moving body under low pressure conditions and provides a traveling path for the moving body.

[0002] Recently, transportation systems designed to allow vehicles to travel at high speeds under low pressure conditions have emerged.

[0003] These high-speed transportation systems deal with two types of resistance depending on speed: designing an aerodynamic vehicle to reduce exponentially increasing air resistance, and applying a magnetic levitation system to reduce friction between the vehicle and the track.

[0004] The technology introduced for this purpose is the Hyperloop device. This Hyperloop device transports a vehicle by magnetic levitation within a sealed tube at a pressure of approximately 0.001 atmosphere or less.

[0005] In a hyperloop device, the tube is usually a single circular steel pipe with a circular cross-section, and the travel path is created by connecting multiple tubes.

[0006] In these hyperloop devices, electromagnetic and mechanical systems are important, but the most important thing is to implement a tube structure that can maintain a sub-vacuum state of about 0.001 atmosphere or less, which accounts for more than 50% of the initial investment cost.

[0007] One aspect of the present disclosure is to provide a tube for a transportation system having an improved structure that can solve the problem of strength reduction due to weight reduction.

[0022] The shapes of the most adjacent segments among the above segments may be identical to each other.

[0048] The operating principle and embodiments of the present invention will be described with reference to the attached drawings below.

[0049] FIG. 1 illustrates a structure in which tubes for a transportation system according to an embodiment of the present disclosure are connected, and FIG. 2 illustrates a structure in which segments of the tube for the transportation system are separated. FIG. 3 illustrates a cross-sectional view of a tube for a transportation system according to an embodiment of the present disclosure, FIG. 4 illustrates an enlarged view of a main portion of FIG. 3, and FIG. 5 illustrates a reinforcing member of a tube for a transportation system according to an embodiment of the present disclosure.

[0050] As illustrated in FIGS. 1 to 5, the tube (1) for the transportation system can provide a travel path for a vehicle traveling under pressure conditions lower than atmospheric pressure.

[0051] Tubes (1) for a transportation system are arranged to have a certain length and are connected continuously to form a travel path of a vehicle.

[0052] A tube (1) for a transportation system may include a plurality of segments (10). The plurality of segments (10) may be arranged along a circumferential direction and joined to each other to form a tube (1) for a transportation system.

[0053] A plurality of segments (10) may be arranged along a direction intersecting the driving path of the vehicle. The plurality of segments (10) may be arranged along the perimeter of the driving path of the vehicle and may be connected to each other to form a driving space in which the vehicle can drive.

[0054] Segments (10) can be connected to each other through welding, adhesive, or fastening devices.

[0055] Each of the plurality of segments (10) may include a segment panel (20) forming a tube body (2). When the segments (10) are mutually connected, the segment panels (20) of the segments (10) may form the tube body (2).

[0056] Each segment panel (20) may be formed into an arch-shaped plate having a predetermined curvature and may form a portion of the tube body (2) in the circumferential direction. The segment panel (20) may be provided to surround the perimeter of the driving space in a cross-section perpendicular to the driving path, and may be formed into an arch-shaped plate that protrudes in a direction away from the center of the driving space. In other words, the segment panel (20) may be formed in an arch shape with respect to the center of the driving space in a cross-section intersecting the driving path.

[0057] The driving path of the driving body can be established through the internal space (2a) of the tube body (2). A guide rail is installed in the internal space (2a), and the driving body can travel at high speed along the driving path while being magnetically levitated from the guide rail by the magnetic force formed between the driving body and the guide rail.

[0058] Here, ultra-high speed can refer to a speed of 300 km / h or more or 700 km / h or more, but is not limited thereto.

[0059] In a transportation system, a magnetic levitation method can be applied to reduce frictional resistance, which is one of the driving resistances generated when a vehicle is moving. By periodically and precisely converting the attractive and repulsive forces of a magnetic field within the internal space (2a) of the tube body (2), a constant gap between the guide rail and the vehicle can be maintained, thereby maintaining the vehicle in a magnetically levitated state.

[0060] The internal space (2a) of the tube body (2) can be maintained in a low pressure state to reduce air resistance when the vehicle is running.

[0061] The pressure of the internal space (2a) can be a pressure close to a vacuum. When the pressure outside the tube (1) for the transportation system is the atmospheric pressure of 1 atm (approximately 101 kPa, 1 bar), the pressure of the internal space (2a) can be less than 10 kPa (approximately 0.1 bar).

[0062] The internal pressure of the internal space (2a) is not limited to this. The internal space (2a) 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 pressures lower than these.

[0063] Hereinafter, the internal pressure of the internal space (2a) will be described based on approximately 100 Pa (1 mbar), which is 0.001 atm. However, the inside of the internal space (2a) can be provided within various pressure ranges including the aforementioned pressure values ​​within a relatively lower range than the atmospheric pressure.

[0064] In a transportation system, a system that electromagnetically or mechanically levitating and propelling a vehicle is important, but it is most important to implement a tube (1) for a transportation system that maintains a vacuum state or a vacuum-like state of 0.001 atm or less in the infrastructure that accounts for more than 50% of the initial investment cost.

[0065] The segment (10) may be made of steel. In order to maintain the driving path of the vehicle at approximately 0.001 atm, it is necessary to strongly suppress the increase in the amount of material within the driving path. To this end, the segment (10) needs to be made of a material with a low outgassing rate. Steel has excellent yield strength and tensile strength, and has a lower outgassing rate than concrete or polymer composite materials. Therefore, the segment (10) made of steel can be advantageously applied to ensure rigidity while maintaining a sub-vacuum driving path of the vehicle inside the tube (1) for the transportation system. The segment panel (20) may be made of a steel plate. The steel plate forming the segment panel (20) may be prepared by bending a flat plate to have a predetermined curvature.

[0066] In addition, in the structure of a tube (1) for a transportation system in which a low pressure is formed inside, it is necessary to simultaneously consider not only the bending load but also the differential pressure load due to the pressure difference between the inside and outside of the tube (1) for the transportation system. Therefore, in order to ensure stable strength of the tube (1) for the transportation system, it is necessary to increase the thickness between the inner and outer surfaces of the tube body (2).

[0067] In a tube (1) for a transportation system according to one embodiment, each segment (10) is provided with a reinforcing member (30) that reinforces a segment panel (20), thereby making it possible to make the thickness between the inner and outer surfaces of the tube body (2) thin while allowing the tube (1) for a transportation system to stably withstand bending loads and differential pressure loads.

[0068] The segment panel (20) is provided as an arch-shaped steel plate having a predetermined curvature, and the reinforcing member (30) can be joined to the segment panel (20) to support the inner surface of the segment panel (20).

[0069] As the inner surface of each segment panel (20) is reinforced by the reinforcing member (30), the tube body (2) can obtain a reinforcing effect equivalent to an increase in thickness as a whole. Accordingly, the tube (1) for a transportation system can be made lighter by reducing the thickness between the inner and outer surfaces of the tube body (2), and at this time, the rigidity corresponding to the reduced thickness of the tube body (2) can be reinforced by the reinforcing member (30). As a result, the tube (1) for a transportation system can solve the problem of strength reduction due to weight reduction.

[0070] In addition, since the tube (1) for the transportation system can be made 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 travel path of the vehicle.

[0071] While the circular steel pipes that make up existing transportation systems rarely exceed 2 m in diameter, those used in passenger or cargo Hyperloop systems can have diameters reaching 4 to 5 m. When these large-diameter circular steel pipes must resist external atmospheric pressure due to internal vacuum rather than internal pressure, the pipes must be relatively thicker to prevent local buckling due to increased compressive stress, unlike when internal pressure is applied.

[0072] In contrast, in the case where the internal cross-sectional area of ​​the tube body (2) that provides the travel path of the vehicle is expanded, the tube (1) for the transportation system according to the present embodiment can prevent local buckling of the tube (1) for the transportation system due to increased compressive stress through the reinforcing member (30) without excessively increasing the thickness of the segment panel (20) of the segment (10) constituting the tube body (2). Therefore, there is no concern that the weight of the tube (1) for the transportation system will excessively increase in response to the expansion of the internal cross-sectional area.

[0073] The reinforcing member (30) can support and reinforce the inner surface of the segment panel (20) along the circumferential direction of the tube body (2).

[0074] The reinforcing member (30) that reinforces the inner surface of the segmented panel (20) in the circumferential direction of the tube body (2) can suppress the circumference of the segmented panel (20) from being deformed inward due to the compressive force of the external atmospheric pressure, thereby increasing the compressive strength of the tube (1) for the transportation system according to the compressive load of the atmospheric pressure.

[0075] A plurality of reinforcing members (30) can be spaced apart from each other along the length of the tube body (2) so that the reinforcing action of the segmented panel (20) by the reinforcing members (30) can be evenly applied to the segmented panel (20) along the length of the tube body (2).

[0076] The reinforcing member (30) transmits the compressive force of the atmospheric pressure acting on the segmented panel (20) and converts it into a tensile force to disperse it, thereby preventing the segmented panel (20) from being locally deformed along the circumferential direction of the tube body (2). For reference, in Fig. 4, the solid arrows indicate the atmospheric pressure acting on the segmented panel (20), and the dotted arrows indicate the direction of the tensile force.

[0077] The reinforcing member (30) is provided to continuously support the inner surface of the segmented panel (20) along the circumferential direction of the tube body (2), so that the function of the reinforcing member (30) to disperse atmospheric pressure can be evenly exerted along the circumferential direction of the tube body (2).

[0078] Therefore, the tube (1) for the transportation system can effectively resist atmospheric pressure even when the thickness of the tube body (2) is not formed excessively thick, and the thin segment panel (20) can contribute to reducing the weight of the tube (1) for the transportation system.

[0079] The reinforcing member (30) can be joined to the segment panel (20) by welding, joining using an adhesive, or a fastening device.

[0080] The reinforcing member (30) may include a first reinforcing portion (31) extending from the segment panel (20) toward the driving space. For example, the first reinforcing portion (31) may be provided in an arcuate shape.

[0081] The first reinforcing member (31) has an arcuate shape with a circumferential surface (31a, 31b) having a curved portion (31a) and a flat portion (31b), and can be joined to be in close contact with the inner surface of the segmented panel (20) through the curved portion (31a). The reinforcing member (30) can smoothly perform the function of dispersing the compressive force acting on the segmented panel (20) while in close contact with the inner surface of the segmented panel (20) through the first reinforcing member (31).

[0082] In addition, the reinforcing member (30) may include a second reinforcing portion (32) extending from the first reinforcing portion (31) in a direction intersecting with the extension direction of the first reinforcing portion (31). For example, the second reinforcing portion (32) may be formed to extend along the longitudinal direction of the flat portion (31b) of the first reinforcing portion (31) to both sides of the flat portion (31b). The first reinforcing portion (31) and the second reinforcing portion (32) may be perpendicular to each other. The first reinforcing portion (31) and the second reinforcing portion (32) may be welded.

[0083] The second reinforcing member (32) can reinforce the first reinforcing member (31). That is, the second reinforcing member (32) reinforces the first reinforcing member (31) to prevent the first reinforcing member (31) from being deformed, thereby ensuring that the reinforcing action of the segmented panel (20) by the first reinforcing member (31) continues stably. The second reinforcing member (32) can also contribute to reducing the weight of the tube (1) for the transportation system by preventing the first reinforcing member (31) from being twisted or bent even when it has a relatively thin thickness.

[0084] The segmented panel (20) has a first flange portion (21) at both ends in the circumferential direction of the tube body (2), and the segmented panels (20) can be joined to each other through the first flange portion (21) so as to be mutually supported. The first flange portion (21) can increase the contact area between the segmented panels (20), thereby increasing the bonding strength between the segmented panels (20).

[0085] The segment panel (20) has a second flange portion (22) at both ends in the longitudinal direction of the tube body (2), and the tubes (1) for the transportation system can be connected by being joined to each other through the second flange portion (22) so as to be mutually supported. The second flange portion (22) can increase the contact area between the tubes (1) for the transportation system, thereby increasing the bonding strength between the tubes (1) for the transportation system.

[0086] The first flange portion (21) can be coupled to be positioned radially outwardly on both ends of the segmented panel (20) in the circumferential direction of the tube body (2), and the second flange portion (22) can be coupled to be positioned radially outwardly on both ends of the segmented panel (20) in the longitudinal direction of the tube body (1).

[0087] The first flange portions (21) of the segmented panels (20) and the second flange portions (22) of the tubes (1) for the transportation system can be joined by welding, or by joining using an adhesive or a fastening device.

[0088] In addition, the tube (1) for the transportation system can be provided so that the cross-sectional shape of the driving space defined by the segmented panels (20) on the cross-section perpendicular to the driving path is a shape other than a circle.

[0089] Among the first reinforcement parts (31) of different segments (10), the first reinforcement parts (31) that are closest to each other along a direction intersecting the travel path can be connected to each other. Here, on the cross-section intersecting the travel path, the first reinforcement parts (31) that are connected to each other can be arranged to define a polygonal space.

[0090] For example, the first reinforcing members (31) connected to each other can define a polygonal space, such as a square or rectangle. Such a polygonal space can improve space utilization compared to a circular cross-section. In other words, by having a cross-section structure closer to a square than a circle, the utilization of the internal space can be optimized.

[0091] In order for the tube body (2) to have a cross-section closer to a square than a circle, the segments (10) may be provided in multiples of four or more. Four or more segments (10) may allow the tube body (2) to have a cross-section closer to a square than a circle. More preferably, the segments (10) may be configured in four pieces so that the cross-section of the tube body (2) becomes as close to a square as possible.

[0092] When there are three segments (10), the tube body has a cross-section closer to a triangle than a square, which may make it more vulnerable in terms of space utilization than when the cross-section is circular.

[0093] A plurality of segments (10) may be provided with sizes and shapes that are compatible with each other so that the tube body (2) can have a cross-section closer to a square shape than a circle, and may be positioned at the same distance from the center (c) of the tube (1) for the transportation system. The segments (10) may be provided identically to each other.

[0094] In addition, in order to reduce the dead space formed in the tube body (2), the segment panel (20) may have a curvature smaller than the curvature of an arc (a) of a circle whose radius is the distance (l) from the center (c) of the tube (1) for the transportation system to the connecting point between adjacent segment panels (20). Here, the center of the tube (1) for the transportation system may be the center of the driving space.

[0095] When designing the curvature of a segment panel (20), the curvature of an arc (a) of a circle whose radius is the distance (l) from the center (c) of a tube (1) for a transportation system to a connecting point between adjacent segment panels (20) can be used as a reference value. The actual curvature of the segment panel (20) can be designed to be smaller than this reference value, so that the tube body (2) has a cross-section closer to a polygon than a circle.

[0096] In this way, the tube (1) for a transportation system having a cross-section closer to a square than a circle, as a tube body (2), can be more advantageous in terms of space utilization compared to the tube of an existing hyperloop device having a circular cross-section.

[0097] For example, when installing a guide rail inside a tube (1) for a transportation system, in the case of a circular steel pipe, the bottom surface of the inner side may be filled to make it flat and the guide rail may be installed thereon. However, in this case, a large dead space may be created in the lower part of the inner side of the tube. In addition, considering that most moving bodies have a cross-sectional structure close to a square, a tube for a transportation system with a tube body having a circular cross-section is likely to have dead space in the upper part and left and right sides of the inner space.

[0098] In contrast, the tube (1) for the transportation system has a cross-sectional structure of a tube body (2) that is closer to a square shape than a circle, thereby reducing the occurrence of dead space inside and increasing the utilization of the space inside.

[0099] The tube (1) for a transportation system configured in this manner can be made lighter by approximately 18.4% or more compared to a tube made of a single circular steel pipe. This was confirmed through an experiment comparing the weight of the tube (1) for a transportation system having almost the same strength and length as a circular steel pipe with that of a circular steel pipe. In this case, the tube body (2) applied to the tube (1) for a transportation system was used having the same internal cross-sectional area as the circular steel pipe.

[0100] As a result of the experiment, it was confirmed that a circular steel pipe with a diameter of 3.5 m, a thickness of 24 mm, and a length of 16 m has a weight of approximately 37.5 tons. In addition, in the case of a tube (1) for a transportation system having almost the same strength and length as this circular steel pipe, it was confirmed that the total weight of the entire tube (1) for a transportation system, while having a tube body (2) having an internal cross-sectional area identical to that of the circular steel pipe and a thickness of approximately 16 mm, was approximately 30.7 tons.

[0101] In addition, the tube (1) for the transportation system can be transported to the construction site in a state before forming the segment (10) or in a state after forming the segment (10) so as to reduce the transport volume during construction.

[0102] Therefore, compared to existing tubes made of a single steel pipe, the tube (1) for the transportation system according to the present embodiment can reduce concerns about transportation difficulties or violations of regulations due to excessive volume during the transportation process for construction.

[0103] For example, for tubes with a diameter of 3 m or more and a length of 16 m or more, special permits may be required to transport them from the factory to the site, or transportation itself may be difficult.

[0104] The segment panels (20) and reinforcing members (30) transported to the construction site can be combined with each other to form segments (10) if they are in a state before forming segments (10). In addition, the segments (10) manufactured at the construction site or the segments (10) transported to the construction site in a state in which segments (10) are formed can be combined with each other at the construction site to produce a tube (1) for a transportation system.

[0105] Figures 6 and 7 illustrate one variant of a tube according to one embodiment.

[0106] As shown in FIGS. 6 and 7, the tube (1) for the transportation system can be provided so that the reinforcing member (30) has a through hole (33).

[0107] A reinforcing member (30) protruding from the inner surface of the tube body (2) can obstruct the air flow within the driving path, thereby reducing the driving speed of the vehicle and increasing the driving energy of the vehicle.

[0108] A reinforcing member (30) having a through hole (33) can improve the flow of air passing through the reinforcing member (30) to make the air flow around the vehicle smooth.

[0109] A through hole (33) may be provided in the first reinforcing member (31). The segmented panel (20) includes an inner surface defining a driving space and an outer surface opposite the inner surface, and the first reinforcing member (31) extends toward the driving space along the inner surface of the segmented panel (20), and a plurality of through holes (33) may be formed in the first reinforcing member (31).

[0110] The through hole (33) is provided to penetrate the first reinforcing member (31) in the longitudinal direction of the tube body (2), thereby improving the flow of air passing through the reinforcing member (30).

[0111] A plurality of through holes (33) can be arranged along the length direction of the first reinforcement part (31) so that the flow of air passing through the first reinforcement part (31) is evenly improved along the length direction of the first reinforcement part (31).

[0112] Unlike the present modified example, the first reinforcing member (31) may be provided in a frame or grid shape. For example, a plurality of first reinforcing members (31) may be spaced apart from each other at a predetermined interval to form a frame shape in the segmented panel (20). These first reinforcing members (31) may be configured to perform the function of the aforementioned through-holes (33) between the first reinforcing members (31).

[0113] Figures 8 and 9 illustrate other variations of the tube according to one embodiment.

[0114] As illustrated in FIGS. 8 and 9, the tube (1) for the transportation system may be provided so that the tube body (2) has a cross-sectional structure close to a rectangle. To this end, the segments (10) may be composed of four segments having a phase difference of 90 degrees along the circumferential direction. The segments (10) may include a pair of first segments (10a) that are symmetrical to each other in the vertical direction, and a pair of second segments (10b) that are symmetrical to each other in the left-right direction. The shapes of the facing segments (10a, 10b) among the segments (10a, 10b) may be identical to each other.

[0115] As illustrated in Fig. 8, the tube (1) for the transportation system may be provided such that the first segment (10a) has a longer length than the second segment (10b). The tube (1) for the transportation system may be provided such that the cross-section of the tube body (2) is close to a rectangle in which the lengths of the upper and lower sides are longer than the lengths of the left and right sides, and thus may be suitable for use as a travel path of a travel body in which the left and right widths are longer than the height.

[0116] As illustrated in Fig. 9, the tube (1) for the transportation system may be configured such that the first segment (10a) has a shorter length than the second segment (10b). The tube (1) for the transportation system may be configured such that the cross-section of the tube body (2) is close to a rectangle in which the lengths of the upper and lower sides are shorter than the lengths of the left and right sides, and thus may be suitable for use as a travel path for a traveler whose height is high compared to the length of the left and right widths.

[0117] In this way, the tube (1) for the transportation system can optimize the utilization of the internal space (2a) according to the characteristics of the vehicle by making the length or size of some segments (10) different.

[0118] The above illustrates and describes specific embodiments. However, the invention is not limited to the above-described embodiments, and those skilled in the art will readily appreciate that various modifications and implementations can be made without departing from the spirit and scope of the invention as set forth in the claims below.
