Description

TECHNICAL FIELD

[0001] The present disclosure relates to a guide tube and a super loop device including the same. BACKGROUND

[0002] Generally, in a high-speed train system capable of reaching a speed of about 300 km / h or more, two types of resistance problems depending on the speed should be solved. One is to solve air resistance that increases exponentially, and the other is to solve friction between a moving vehicle and a track.

[0003] A technology introduced for this purpose is a super loop device. Such a super loop device is a system for transferring a moving vehicle by magnetic levitation in a sealed tube at a pressure of about 0.001 atm or less.

[0004] In such a super loop device, although an electromagnetic system and a mechanical system are important, it is important to implement a tube structure to maintain a sub-atmospheric state of about 0.001 atm or less, which accounts for about 50% or more of initial investment costs.

[0005] In addition, a track support member, i.e., a guide rail, installed in the tube needs to be maintained straight because it resists the load of the moving vehicle and guides the moving vehicle. That is, if the track support member cannot maintain a constant displacement tolerance (about 2 mm or less), problems such as deviation of the moving vehicle while traveling can occur.

[0006] Factors directly affecting the straightening of the track support member include deflection caused by the self-weight of the tube and the moving vehicle and travel deflection caused by vibrations generated during travel of the moving vehicle.

[0007] In order to control such a situation, the installation position of the track support member should be adjusted to compensate for deflection caused by the self-weight of the tube and deflection caused by the moving vehicle at the start, and the stiffness of the tube should be sufficiently ensured to resist vibrations.

[0008] Such a conventional method is configured to form a support point by manufacturing a through-hole in the tube to compensate for the initial deflection of the track support member, connecting a bolt member to the through-hole, and then welding the bolt member. A method of coupling the track support member to the bolt member is used.

[0009] However, the limitation of such a conventional method is that a through-hole must be formed in the tube, a bolt member is inserted into the through-hole, and then welding is performed to fill the remaining portion of the through-hole.

[0010] Such a drilling operation of the through-hole is expensive and time-consuming, and particularly, it is difficult to form the through-hole obliquely in the pipe such that the through-hole is horizontal to the moving vehicle rather than in the circumferential direction of the pipe. In addition, it is necessary to maintain the vacuum state inside the pipe after the through-hole is drilled by performing a filler welding, but there is a limitation that the vacuum of the pipe cannot be ensured depending on the reliability of the operation.

[0011] Therefore, there is a need to research a guide pipe and a super loop device including the same to improve the above-mentioned problems or limitations. SUMMARY

[0043] Hereinafter, embodiments of the present disclosure will be described below with reference to the accompanying drawings. However, the present disclosure can be exemplified in many different forms, and should not be interpreted as being limited to the specific embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art. Accordingly, for the sake of clarity, the shapes and sizes of elements in the drawings can be exaggerated, and elements indicated by the same reference numerals are the same elements in the drawings.

[0044] Further, in this specification, unless the context clearly indicates otherwise, a singular expression includes a plural expression, and throughout the specification, the same reference numerals or like designations designate the same elements or corresponding elements.

[0045] ​The present disclosure relates to a guide tube 1 and a super loop device including the same, and a rail support member 30 can be easily installed in the guide tube. That is, since the rib member 20 in which the rail support member 30 is installed is coupled to the inner surface of the tube body member 10 without forming a through hole on the tube body member 10, the rail support member 30 can be easily installed.

[0046] In another aspect, the guide tube 1 and the super loop device including the same can improve a deflection problem caused by the self-weight of the tube body member 10, vibration of a moving vehicle 3, etc. That is, a problem in which the tube body member 10 is deflected due to the rib member 20 disposed in the longitudinal direction of the tube body member 10 can be improved. Further, the friction damper portion 22 can be provided to absorb vibration as a frictional force, thereby improving a problem in which the tube body member 10 is deflected due to vibration.

[0047] Specifically, referring to the drawings, Figure 1 is a perspective view illustrating a guide tube 1 of the present disclosure, and Figure 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 Figure 3 is a perspective view illustrating the 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 can include a tube body member 10, a rib member 20, and a rail support member 30.

[0048] Here, the rib member 20 can be disposed in the longitudinal direction of the tube body member 10 and can be coupled to the inner surface of the tube body member 10. The rail support member 30 can be connected to the rib member 20.

[0049] As described above, since the rib member 20 is disposed and coupled in the longitudinal direction of the tube body member 10, the rib member 20 also functions to support the tube body member 10 in the lengthwise direction thereof.

[0050] Accordingly, a problem in which the tube body member 10 is deflected due to the inherent weight can be improved. This can be confirmed with reference to the simulation results of Figure 12 .

[0051] That is, Figure 12 is simulation results illustrating a comparison of deflection deformation of a conventional tube and the guide tube 1 of the present disclosure, and Figure 12 (a) of FIG. 10 illustrates simulation results of a conventional form, and Figure 12 (b) of FIG. 10 illustrates simulation results of the guide tube 1 of the present disclosure.

[0052] Here, in the case of the prior art, a deflection of 0.52 mm occurs at the upper end portion, but the guide tube 1 of the present disclosure deflects only 0.49 mm, and thus it can be seen that the present disclosure has an effect of improving the deflection problem by about 6% compared to the prior art.

[0053] Further, in the case of the prior art, a deflection of 0.20 mm occurs at the lower end portion, but the guide tube 1 of the present disclosure has a deflection of only 0.19 mm, and thus it can be seen that the present disclosure has an effect of improving the deflection problem by about 5% compared to the prior art.

[0054] 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 body member 10, the cost generated due to the inclined formation of the through-hole in the tube body member 10 can be reduced, and further, the problem that the reliability of the filling operation according to the through-hole can not be able to secure the inside of the tube body member 10 to be in a sub-vacuum state of about 0.001 atm or less can be reduced because the operation for filling the through-hole is unnecessary.

[0055] Here, the rib member 20 of the guide tube 1 according to the embodiment of the present disclosure can be welded and coupled to the tube body member 10 formed in a tubular shape made of a metal material. In other words, the rib member 20 can be coupled to the tube body member 10 by direct welding without forming a separate through-hole for coupling to the inner surface of the tube body member 10.

[0056] Figure 4 is a cross-sectional view illustrating a partial cut of the rail support member 30 and the rib member 20 coupled to the bolt member 40 in the guide tube of the present disclosure. Referring to Figure 4 , the rail support member 30 of the guide tube 1 according to the embodiment of the present disclosure can be screwed and coupled to the 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.

[0057] That is, when the rail support member 30 is coupled to the bolt member 40 provided in the rib member 20, the rail support member 30 can be coupled to the rib member 20 coupled to the tube body member 10.

[0058] Here, the bolt member 40 can be welded and coupled to the rib member 20, but can also be screwed and coupled to the rib member 20 to adjust the distance between the bolt member 40 and the rib member 20 when coupled to the rib member 20. Accordingly, the distance between the rail support member 30 and the rib member 20 can be adjusted.

[0059] Further, the rail support member 30 of the guide tube 1 according to the embodiment of the present disclosure can adjust the depth to be screwed and coupled to the bolt member 40 to adjust the interval from the rib member 20.

[0060] That is, the adjustment of the interval between the rail support member 30 and the rib member 20 can be performed by adjusting the coupling degree between the rib member 20 and the bolt member 40, but can also be performed by adjusting the coupling degree between the rail support member 30 and the bolt member 40.

[0061] Figure 5 is a perspective view illustrating an embodiment in which the rib member 20 in the guide tube 1 of the present disclosure includes a coupling protrusion portion 21, and Figure 6 is a perspective view illustrating a state in which the rib member 20 including the coupling protrusion portion 21 in the guide tube 1 of the present disclosure is coupled to the tube body member 10. Referring to the drawings, the rib member 20 of the guide tube 1 according to the embodiment of the present disclosure can include the coupling protrusion portion 21.

[0062] Here, the coupling protrusion portion 21 is formed to protrude in the direction of the inner surface of the tube body member 10, is disposed in a plurality along the longitudinal direction of the tube body member 10, and is welded and coupled to the inner surface of the tube body member 10.

[0063] As described above, since the rib member 20 is coupled to the tube body member 10 through the coupling protrusion portion 21, the welding coupling portion can be reduced when being welded and coupled to the tube body member 10, so that the coupling operation can be easily performed.

[0064] Figure 7 is a perspective view illustrating an embodiment in which the rib member 20 in the guide tube 1 of the present disclosure includes a friction damper portion 22, and Figure 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 the embodiment of the present disclosure can include the friction damper portion 22.

[0065] Here, the friction damper portion 22 can have a slit hole 22a, a portion of the rail support member 30 is fitted to the slit hole and is connected in the slit hole to absorb the vibration energy of the rail support member 30.

[0066] That is, when the friction damper portion 22 supports to move the rail support member 30 in the shape direction of the slit hole 22a, the friction damper portion 22 can dissipate the vibration energy generated by the moving vehicle 3, external factors, etc.

[0067] In particular, the friction damper portion 22 absorbs vibration energy using frictional force acting between the rail support member 30 and the rail support member 30 as a resistance, thereby improving problems caused by vibration.

[0068] That is, the slit hole 22a of the guide tube 1 according to the embodiment of the present disclosure is in frictional contact with the rail support member 30 to absorb vibration energy.

[0069] Here, the slit hole 22a of the guide tube 1 according to the embodiment of the present disclosure can be formed in a horizontal shape or an inclined shape along the width direction of the rib member 20.

[0070] The form of the slit hole 22a is not limited to the above-described form, and the slit hole 22a of the present disclosure can be used as long as it can effectively absorb vibration energy.

[0071] Further, a buffer spring 22b can be provided in the slit hole 22a to more effectively absorb vibration energy, and it will be described with reference to Figure 9 The buffer spring 22b will be described in detail.

[0072] Figure 9 is a side view illustrating an embodiment in which the friction damper portion 22 in the guide tube 1 of the present disclosure includes the buffer spring 22b. Referring to Figure 9 The friction damper portion 22 of the guide tube 1 according to the embodiment of the present disclosure can include the buffer spring 22b provided in at least one end portion of the slit hole 22a.

[0073] That is, since the buffer spring 22b is provided in one end portion in the longitudinal direction of the slit hole 22a through which the rail support member 30 moves, the buffer spring 22b is provided on a path on which the rail support member 30 moves due to vibration. Accordingly, the elastic force of the buffer spring 22b becomes a resistance to buffer movement caused by vibration of the rail support member 30, thereby dissipating vibration energy applied to the rail support member 30.

[0074] In other words, in addition to being dissipated as frictional energy of the slit hole 22a, vibration energy of the rail support member 30 can be dissipated as elastic energy of the buffer spring 22b.

[0075] In order to install the rail support member 30 to be fitted to the friction damper portion 22, the rib member 20 can be configured such that the upper end portion of the slit hole 22a is open, such that the top portion thereof is separated.

[0076] That is, in the rib member 20, when the rail support member 30 is fitted to the slit hole 22a of which the upper end portion is open, in a state in which the rib top portion 20a is separated as a top portion, the rib top portion 20a can be disposed again on the top portion and coupled by welding or the like to be assembled so as to close the upper end portion of the slit hole 22a.

[0077] Further, the rail support member 30 can include an insertion protrusion portion 31 and a stopper portion 32 so that the position of the rail support member 30 does not deviate when moving from the slit hole 22a of the rib member 20, while dissipating vibration energy.

[0078] That is, Figure 10 is a plan view illustrating a cross-sectional view of a portion A-A' in Figure 7 Referring to Figure 10 , the rail support member 30 of the guide tube 1 according to an embodiment of the disclosure can include an insertion protrusion portion 31 and a stopper portion 32.

[0079] Here, the insertion protrusion 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 protrusion portion 31 to form a stepped portion.

[0080] In other words, the insertion protrusion portion 31 is fitted to the slit hole 22a so that the rail support member 30 moves along the slit hole 22a, and is used to dissipate vibration energy transferred to the rail support member 30. The stopper portion 32 is used to support so as not to be separated when the insertion protrusion portion 31 moves along the slit hole 22a.

[0081] As shown in Figure 10 , the rail support member 30 is provided in a shape in which one side of a letter "O" is open, and the insertion protrusion portion 31 is formed to protrude from the open portion, and the stopper portion 32 can be formed in the form of a step in the vicinity.

[0082] In the disclosure, a hyper loop device provided with the above-described guide tube 1 can be included. That is, Figure 11 is a front view illustrating a guide tube 1 of the disclosure and a hyper loop device including the same. Referring to Figure 11 , a hyper loop device according to another embodiment of the disclosure can include a guide tube 1, an electromagnet member 2, and a moving vehicle 3.

[0083] 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 the transportation of the moving vehicle 3 is adjusted by a magnetic force applied between the electromagnet member 2 and the permanent magnet 3a, and the moving vehicle 3 is configured to have a receiving space formed therein.

[0084] As described above, the magnetic levitation and movement of the mobile vehicle 3 can be performed by the mutual attraction and repulsion between the permanent magnet 3a and the electromagnet member 2.

[0085] The electromagnet member 2 can be configured to adjust the magnetic force formation by adjusting the current applied to the electric steel plate.

[0086] Hereinafter, the present disclosure will be described in more detail by way of 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.
