MODE FOR INVENTION

[0040] Hereinafter, embodiments of the present disclosure will be described as follows with reference to the attached drawings. The present disclosure may, however, be exemplified in many different forms and should not be construed as being limited to the specific embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Accordingly, shapes and sizes of elements in the drawings may be exaggerated for clarity of description, and elements indicated by the same reference numeral are same elements in the drawings.

[0041] In addition, in this specification, the singular expression includes the plural expression unless the context clearly dictates otherwise, and the same reference signs or reference signs assigned in a similar manner throughout the specification refer to the same element or corresponding element.

[0042] The present disclosure relates to a guide tube 1 and a hyperloop device including the same, and a rail support member 30 may be easily installed therein. That is, since a rib member 20 having the rail support member 30 installed is coupled to an inner surface of a tube main body member 10 without forming a through-hole on the tube main body member 10, the rail support member 30 may be easily installed.

[0043] In another aspect, the guide tube 1 and the hyperloop device including the same may improve a problem of deflection caused by the own weight of the tube main body member 10, vibration of a moving vehicle 3, or the like. That is, it is possible to improve a problem in which the tube main body member 10 is deflected by the rib member 20 disposed in a longitudinal direction of the tube main body member 10. In addition, a friction damper portion 22 may be provided to absorb vibration as frictional force, thereby improving the problem of deflection of the tube main body member 10 due to vibration.

[0044] Specifically, referring to the drawings, FIG. 1 is a perspective view illustrating a guide tube 1 of the present disclosure, and FIG. 2 is a perspective view illustrating a rib member 20 and a rail support member 30 in the guide tube 1 of the present disclosure, and FIG. 3 is a perspective view illustrating a rail support member 30 coupled to the rib member 20 via a bolt member 40 in the guide tube 1 of the present disclosure. Referring to the drawings, the guide tube 1 according to an embodiment of the present disclosure may include a tube main body member 10, a rib member 20, and a rail support member 30.

[0045] Here, the rib member 20 may be disposed in a longitudinal direction of the tube main body member 10, and may be coupled to the inner surface of the tube main body member 10. The rail support member 30 may be connected to the rib member 20.

[0046] As described above, since the rib member 20 is disposed and coupled in the longitudinal direction of the tube main body member 10, it also serves to support the tube main body member 10 in the length direction thereof.

[0047] Accordingly, it is possible to improve a problem that the tube main body member 10 is deflected due to inherent weight. This can be confirmed with reference to a simulation result of FIG. 12.

[0048] That is, FIG. 12 is a simulation result illustrating a comparison of deflection deformation of the conventional tube and the guide tube 1 of the present disclosure, and FIG. 12(a) illustrates a conventional form, and FIG. 12(b) illustrates the guide tube 1 of the present disclosure.

[0049] Here, in a case of prior art, deflection of 0.52 mm occurs at an upper end, but the guide tube 1 of the present disclosure deflects only by 0.49 mm, so it can be seen that there is an effect of improving a problem of deflection by about 6%, compared to the prior art.

[0050] In addition, in the case of the prior art, 0.20 mm of deflection occurs at a lower end, but the guide tube 1 of the present disclosure has only 0.19 mm deflection, so it can be seen that there is an effect of improving the problem of deflection by about 5%, as compared to the prior art.

[0051] As described above, in the guide tube 1 of the present disclosure, since the rail support member 30 can be installed in the rib member 20 without forming a through-hole in the tube main body member 10, it is possible to reduce a cost as the through-hole is formed obliquely in the tube main body member 10, and in addition, a problem in which an inside of the tube main body member 10 may not be ensured to be in a sub-vacuum state of about 0.001 atmosphere or less depending on reliability of a filling operation of the through-hole, since the operation for filling the through-hole is unnecessary.

[0052] Here, the rib member 20 of the guide tube 1 according to an embodiment of the present disclosure may be welded and coupled to the tube main body member 10 made of a metal material formed in a tube shape. In other words, the rib member 20 may be coupled thereto through direct welding without forming a separate through-hole for coupling to the inner surface of the tube main body member 10.

[0053] FIG. 4 is a partially cut cross-sectional view illustrating a rib member 20 and a rail support member 30 coupled to a bolt member 40 in the guide tube 1 of the present disclosure. Referring to FIG. 4, the rail support member 30 of the guide tube 1 according to an embodiment of the present disclosure may be screwed and coupled to a bolt member 40, screwed and coupled or welded and coupled to the rib member 20, and connected to the rib member 20 via the bolt member 40.

[0054] That is, as the rail support member 30 is coupled to the bolt member 40 provided in the rib member 20, the rail support member 30 may be coupled to the rib member 20 coupled to the tube main body member 10.

[0055] Here, the bolt member 40 may be welded and coupled to the rib member 20, but may be screwed and coupled, to adjust a spacing therebetween while coupled to the rib member 20. As a result, the spacing between the rail support member 30 and the rib member 20 may be adjusted.

[0056] In addition, the rail support member 30 of the guide tube 1 according to an embodiment of the present disclosure may adjust a depth to be screwed and coupled to the bolt member 40, to adjust the spacing with the rib member 20.

[0057] That is, adjustment of the spacing between the rail support member 30 and the rib member 20 may be performed by adjusting a degree of coupling between the rib member 20 and the bolt member 40, but also by adjusting a degree of coupling between the rail support member 30 and the bolt member 40.

[0058] FIG. 5 is a perspective view illustrating an embodiment in which a rib member 20 includes a coupling tab portion 21 in the guide tube 1 of the present disclosure, and FIG. 6 is a perspective view illustrating a state in which a rib member 20 including a coupling tab portion 21 is coupled to a tube main body member 10 in the guide tube 1 of the present disclosure. Referring to the drawings, the rib member 20 of the guide tube 1 according to an embodiment of the present disclosure may include a coupling tab portion 21.

[0059] Here, the coupling tab portion 21 is formed to protrude in a direction of an inner surface of the tube main body member 10, is provided in plural in a longitudinal direction of the tube main body member 10, and is welded and coupled to the inner surface of the tube main body member 10.

[0060] As described above, since the rib member 20 is coupled to the tube main body member 10 through the coupling tab portion 21, it is possible to reduce a welding coupling portion when being welded and coupled to the tube main body member 10, so that a coupling operation may be easily performed.

[0061] FIG. 7 is a perspective view illustrating an embodiment in which a rib member 20 includes a friction damper portion 22 in the guide tube 1 of the present disclosures, and FIG. 8 is a perspective view illustrating an operating state of the friction damper portion 22 in the guide tube 1 of the present disclosure. Referring to the drawings, the rib member 20 of the guide tube 1 according to an embodiment of the present disclosure may include a friction damper portion 22.

[0062] Here, the friction damper portion 22 may have a slit hole 22a in which the rail support member 30 is fitted to a portion of the slit hole and is connected, to absorb vibration energy of the rail support member 30.

[0063] That is, the friction damper portion 22 may dissipate vibration energy generated by the moving vehicle 3, external factors, and the like, as the friction damper portion 22 supports to move the rail support member 30 in a slit hole 22a shape direction.

[0064] In particular, the friction damper portion 22 uses frictional force acting between the rail support member 30 and the rail support member 30 as resistive force to absorb the vibration energy, thereby improving the problem caused by vibration.

[0065] That is, the slit hole 22a of the guide tube 1 according to an embodiment of the present disclosure is in frictional contact with the rail support member 30 to absorb vibration energy.

[0066] Here, the slit hole 22a of the guide tube 1 according to an embodiment of the present disclosure may be formed in a horizontal shape or an inclined shape in a width direction of the rib member 20.

[0067] A form of the slit hole 22a is not limited to the above-described form, and the slit hole 22a of the present disclosure may be used as long as it can effectively absorb vibration energy.

[0068] In addition, a buffer spring 22b may be provided in the slit hole 22a to more effectively absorb vibration energy, and a detailed description thereof will be described with reference to FIG. 9.

[0069] FIG. 9 is a side view illustrating an embodiment in which a friction damper portion 22 includes a buffer spring 22b in the guide tube 1 of the present disclosure. Referring to FIG. 9, the friction damper portion 22 of the guide tube 1 according to an embodiment of the present disclosure may include a buffer spring 22b provided in at least one end portion of the slit hole 22a.

[0070] That is, since the buffer spring 22b is provided in one end portion in a longitudinal direction of the slit hole 22a through which the rail support member 30 moves, the buffer spring 22b is disposed on a path on which the rail support member 30 moves by vibration. Accordingly, an elastic force of the buffer spring 22b becomes a resistive force to buffer the movement caused by the vibration of the rail support member 30, thereby dissipating vibration energy applied to the rail support member 30.

[0071] In other words, the vibration energy of the rail support member 30 may be dissipated as elastic energy of the buffer spring 22b in addition to being dissipated as friction energy with the slit hole 22a.

[0072] In order to install the rail support member 30 to be fitted to the friction damper portion 22, the rib member 20 may be configured such that an upper end portion of the slit hole 22a is opened so that a top portion thereof is separated.

[0073] That is, in the rib member 20, when the rail support member 30 is fitted to the slit-hole 22a in which an upper end portion thereof is opened, in a state in which a rib top portion 20a, which is a top portion, is separated, the rib top portion 20a may be disposed on the top portion again and coupled by welding, or the like, to be assembled to close the upper end portion of the slit hole 22a.

[0074] In addition, the rail support member 30 may include an insertion tab portion 31 and a stopper portion 32, so that a position thereof is not deviated while being moved from the slit hole 22a of the rib member 20 while dissipating vibration energy.

[0075] That is, FIG. 10 is a plan view illustrating a cut section of part A-A′ in FIG. 7. Referring to FIG. 10, the rail support member 30 of the guide tube 1 according to an embodiment of the present disclosure may include an insertion tab portion 31 and a stopper portion 32.

[0076] Here, the insertion tab portion 31 is configured to be fitted to the slit hole 22a. The stopper portion 32 is configured to protrude in at least one direction of the insertion tab portion 31 to form a step portion.

[0077] In other words, the insertion tab portion 31 is fitted to the slit hole 22a so that the rail support member 30 moves along the slit hole 22a, and serves to dissipate vibration energy transmitted to the rail support member 30. The stopper portion 32 serves to support not to be separated, when the insertion tab portion 31 moves along the slit hole 22a.

[0078] As showed in FIG. 10, the rail support member 30 is provided in a shape in which a portion of one side of a letter “□” is opened, and an insertion tab portion 31 is formed to protrude from this broken portion, and a stopper portion 32 may be formed in a form of a step therearound.

[0079] In the present disclosure, a hyperloop device provided with the guide tube 1 described above may be included. That is, FIG. 11 is a front view illustrating a guide tube 1 of the present disclosure and a hyperloop device including the same. Referring to FIG. 11, the hyperloop device according to another embodiment of the present disclosure may include the guide tube 1, an electromagnet member 2, and a moving vehicle 3.

[0080] Here, the electromagnet member 2 is configured to be coupled to the rail support member 30. The moving vehicle 3 is provided with a permanent magnet 3a facing the electromagnet member 2, and a transport of the moving vehicle 3 is adjusted by magnetic force applied between the electromagnet member 2 and the permanent magnet 3a, and is configured to have an accommodation space formed therein.

[0081] As described above, magnetic levitation and movement of the moving vehicle 3 may be performed by an action of mutual attraction and repulsion between the permanent magnet 3a and the electromagnet member 2.

[0082] The electromagnet member 2 may be configured to adjust magnetic force formation by adjusting a current applied to an electrical steel sheet.

[0083] Hereinafter, the present disclosure will be described in more detail through examples. However, it should be noted that the following examples are for illustrative purposes only and are not intended to limit the scope of the present disclosure. The scope of the present disclosure may be determined by matters described in the claims and matters able to be reasonably inferred therefrom. The subject of the present invention is not limited to the above. The subject of the present invention will be understood from the overall content of the present specification, and those of ordinary skill in the art to which the present invention pertains will have no difficulty in understanding the additional subject of the present invention.

[0084] While example embodiments have been shown and described above, it will be apparent to those skilled in the art that modifications and variations could be made without departing from the scope of the present disclosure as defined by the appended claims.
