[0052] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0053] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0054] Combination Figure 1 , Figure 2 and Figure 4 As shown, the embodiment of the present disclosure provides a satellite-rocket assembly heavy track vertical transport system, which includes a basic track 1, a rotary track conversion device 2 and a translational track conversion device 3; a plurality of basic tracks 1 are provided, and the plurality of basic tracks 1 form a cross-junction 11 and a tangent junction 12; the rotary track conversion device 2 is provided at the cross-junction 11; the translational track conversion device 3 is provided at the tangent junction 12;

[0055] Among them, the rotating track conversion device 2 includes a rotating table 21 and a rotating drive mechanism 22 that is transmission-connected to the rotating table 21; the translational track conversion device 3 includes a translational table 31 and a translational drive mechanism 32 that is transmission-connected to the translational table 31; the rotating table 21 and the translational table 31 are respectively provided with track-changing rail sections; the track-changing rail sections can rotate synchronously with the rotating table 21, or move synchronously with the translational table 31, so as to switch the docking state between themselves and different base tracks 1.

[0056] The satellite-rocket combination heavy-duty orbit vertical transfer system can be specifically but not limited to being used in a composite system of straight-curved orbits in a heavy-duty carrier orbit in a space launch vehicle launch site, and this is used as an example to illustrate this.

[0057] When the satellite-rocket combination heavy-duty track vertical transfer system is used in practice, first, pits are dug at the intersection 11 and the tangent intersection 12 of the basic track 1, and a rotary track conversion device 2 and a translational track conversion device 3 are respectively arranged in the pits. In this way, the rotating platform 21 in the rotary track conversion device 2 can drive the track switching segment to rotate synchronously, and the translational platform 31 in the translational track conversion device 3 can drive the track switching segment to move synchronously, so as to change the actual docking state between the track switching segment and different basic tracks 1. Therefore, the actual transportation path of the fixed-laid basic track 1 can be flexibly adjusted and changed, so that it is possible to realize the rapid switching between the vertical assembly and test plants of multiple launch vehicles and different launch towers, which greatly improves the transportation path flexibility and transportation function diversity of the fixed-laid heavy-duty carrier track, enables the fixed-laid heavy-duty carrier track to meet the needs of heavier and more diverse launch missions, and significantly improves the economic benefits of the fixed-laid heavy-duty carrier track.

[0058] When the rotary track conversion device 2 needs to convert the intersection 11, it only needs to drive the rotating platform 21 to slide and rotate a certain angle through the rotating drive mechanism 22 to change the actual position of the reversing rail segment in the rotating platform 21, so that the reversing rail segment can be docked with multiple tracks at the intersection 11 in the track respectively, thereby realizing the function of switching the actual guide path of the intersection 11 of the track.

[0059] When the translational track conversion device 3 needs to convert the tangent junction 12, it only needs to drive the translation stage 31 to translate and slide a certain distance through the translation drive mechanism 32, so as to change the actual position of the track switching section in the translation stage 31, so that the track switching section can be switched and docked with the tangent junction 12 in the track, thereby realizing the function of switching the actual guide path of the tangent junction 12 of the track.

[0060] In summary, the heavy-duty rail vertical transfer system for star-rocket assemblies provided in the embodiments of the present disclosure has the beneficial effect of greatly improving the flexibility of fixed heavy-duty rail transportation paths and the diversity of transportation functions, realizing flexible switching of the guide paths at the intersection junction 11 and the tangent junction 12 of the straight rail and the curved rail, and greatly improving the economic cost-effectiveness of fixed rail construction.

[0061] In addition, the heavy-duty orbit vertical transfer system of the satellite-rocket combination can also expand the application of heavy-duty transport orbit types to conversion combinations between straight-straight, straight-curved, curved-curved and other orbits, with significant economic benefits.

[0062] In one embodiment, the rotary track conversion device 2 also includes an arc liner rail assembly 23; the arc liner rail assembly 23 is supported on the lower side of the rotating platform 21; the rotating platform 21 can be driven by the rotating drive mechanism 22 to reciprocate along the arc liner rail assembly 23 to different positions.

[0063] Specific, combined Figure 5 To further explain in detail, the arc rail assembly 23 can be specifically arranged into multiple ones and arranged concentrically with the center of the rotating table 21, and each arc rail assembly 23 has a rolling body that abuts and supports the rotating table 21, and the multiple arc rail assemblies 23 are symmetrically distributed about the central axis of the rotating table 21. In this way, when the rotating table 21 rotates relatively along the arc rail assembly 23, the rotation direction of the rotating table 21 can be consistent with the curvature extension direction of the multiple arc rail assemblies 23, and the rolling bodies in the arc rail assembly 23 can greatly reduce the friction resistance of the rotating table 21 during rotation, thereby fully improving the smoothness of the rotation of the rotating table 21.

[0064] Furthermore, the rolling elements in the arc liner rail assembly 23 may be, but are not limited to, spherical balls or cylindrical needles, and are embedded in the side of the arc liner rail assembly 23 facing the rotating platform 21 .

[0065] In one embodiment, the translational track conversion device 3 also includes a strip rail assembly 33; the strip rail assembly 33 is supported on the lower side of the translation stage 31; the translation stage 31 can be driven by the translation drive mechanism 32 to reciprocate along the strip rail assembly 33 to different positions.

[0066] Specific, combined Figure 3 To further explain in detail, the strip rail assembly 33 is specifically configured as a plurality of parallel and spaced strips, and each strip rail assembly 33 has a rolling body that is abutted and supported by the translation stage 31, and the plurality of strip rail assemblies 33 extend along the width direction of the translation stage 31 and are spaced parallel to each other, so that when the translation stage 31 is relatively translated along the strip rail assembly 33, the moving direction of the translation stage 31 can be consistent with the extension direction of the plurality of strip rail assemblies 33, and the rolling bodies in the strip rail assembly 33 can greatly reduce the friction resistance of the translation stage 31 during translation, thereby fully improving the smoothness of the translation stage 31 during translation and sliding.

[0067] Furthermore, the rolling elements in the strip rail assembly 33 may be, but are not limited to, spherical balls or cylindrical needles, and are embedded in the side of the strip rail assembly 33 facing the translation stage 31 .

[0068] The specific arrangement of the strip rail assembly 33 has the beneficial effects of simple structure, being able to stably support the translation of the translation stage 31 , and reducing the friction resistance when the translation stage 31 moves.

[0069] In one possible implementation manner, the translational track conversion device 3 further includes a guide wheel group; the guide wheel group is arranged between the strip rail assembly 33 and the translation stage 31, and is used to guide and support the translation stage 31 to move.

[0070] Specific, combined Figure 3 To further explain in detail, a guide wheel group is further arranged between the strip rail assembly 33 and the translation stage 31. In addition to being able to support the translation stage 31 together with the strip rail assembly 33, the guide wheel group can also guide and limit the moving direction of the translation stage 31, thereby fully ensuring the accuracy of the displacement direction of the translation stage 31 when the translation drive mechanism 32 drives the translation stage 31.

[0071] In one embodiment, the rotating track conversion device 2 and the translational track conversion device 3 both include an anti-overturning positioning mechanism 4; the anti-overturning positioning mechanism 4 is detachably arranged on the lower side of the rotating stage 21 and the translational stage 31; the anti-overturning positioning mechanism 4 is used to limit and fix the rotating stage 21 and the translational stage 31.

[0072] Specific, combined Figure 5 To further explain in detail, an anti-rollover positioning mechanism 4 is provided on the lower side of the rotating table 21 and the translation table 31 to limit the connection with them. In this way, when the translation table 31 is translated to the position where it is docked with the track by the translation driving mechanism 32, or the rotating table 21 is rotated to the position where it is docked with the track by the rotation driving mechanism 22, the anti-rollover positioning mechanism 4 can limit and fix the translation table 31 and the rotating table 21 to ensure the firmness of the docking between the translation table 31 or the track section in the rotating table 21 and the track, and the anti-rollover positioning mechanism 4 can also limit the rotating table 21 and the translation table 31 to prevent overturning. In this way, when a heavy load is transported to the rotating table 21 and the translation table 31, the lateral force on one side of the rotating table 21 and the translation table 31 can be prevented from being too large, causing the problem of tilting or overturning.

[0073] The above-mentioned anti-overturning positioning mechanism 4 can be specifically configured into a variety of structures, for example, it can be configured as a supporting anti-overturning positioning rod similar to a hydraulic jack structure to respectively perform anti-overturning support and limit the side edges of the rotating platform 21 and the translation platform 31, or it can be configured as a compression elastic positioning member similar to a spring sheet structure to respectively perform anti-overturning support and limit the side edges of the rotating platform 21 and the translation platform 31.

[0074] In one embodiment, the anti-overturning positioning mechanism 4 includes a positioning pin 41 and an anti-overturning hook 42; the positioning pin 41 can be detachably inserted into the pin holes in the rotating stage 21 and the translation stage 31; the anti-overturning hook 42 can be detachably hooked and connected to the sides of the rotating stage 21 and the translation stage 31; wherein, the positioning pin 41 and the anti-overturning hook 42 are respectively arranged in plurality along the circumferential direction of the rotating stage 21 and the longitudinal direction of the translation stage 31.

[0075] Specific, combined Figure 5 To further explain in detail, the anti-overturning positioning mechanism 4 is specifically configured to include a positioning pin 41 and an anti-overturning hook 42, and the positioning pin 41 can be detachably inserted into the corresponding pin holes in the rotating stage 21 and the translation stage 31, and the relative positioning and limiting function of the rotating stage 21 and the translation stage 31 can be achieved by manually installing the positioning pin 41; the anti-overturning hook 42 can be detachably hooked and hung on the edge sides of the rotating stage 21 and the translation stage 31 to further improve the anti-overturning reliability of the rotating stage 21 and the translation stage 31.

[0076] The specific setting method of the above-mentioned anti-overturning positioning mechanism 4 has a simple structure and can stably realize the anti-overturning positioning function of the rotating platform 21 and the translation platform 31, fully ensuring the safety and reliability of the heavy-duty orbit vertical transfer system of the satellite-rocket combination during heavy-load operation.

[0077] In one possible implementation manner, two intersection junctions 11 and two tangent junctions 12 are respectively arranged in an interlaced manner along the path direction of the base track 1 .

[0078] Specific, combined Figure 1 To further explain in detail, two intersection junctions 11 and two tangent junctions 12 are respectively arranged in an interlaced manner along the path direction of the basic orbit 1, that is, two rotary orbit conversion devices 2 and two translational orbit conversion devices 3 are respectively arranged in an interlaced manner along the path direction of the basic orbit 1. This can further improve the flexibility of the transportation paths of multiple basic orbits 1 at the intersection junctions 11 and the tangent junctions 12, so that the heavy-duty orbit vertical transfer system of the satellite-rocket combination can have more diverse transportation options to fully adapt to heavier and more diverse launch mission requirements.

[0079] In one possible implementation mode, the satellite-rocket combination heavy-duty orbit vertical transfer system also includes a pit flap 5; the pit flap 5 is arranged on the side of the rotating platform 21 and the translation platform 31; the pit flap 5 can be folded and stored inward, or folded and stretched outward; and when the pit flap 5 is folded and stretched outward, it can cover the gap formed by the rotating platform 21 or the translation platform 31 and the pit.

[0080] Specific, combined Figure 3To further explain in detail, the heavy-duty orbital vertical transfer system of the star-rocket combination also includes a pit flap 5 arranged on the side of the rotating platform 21 and the translation platform 31, and the pit flap 5 can be folded and stored inward, or folded and stretched outward, so that when the rotating platform 21 or the translation platform 31 is adjusted to the required position accordingly, the pit flap 5 can be folded and stretched outward, and the gap between the rotating platform 21 or the translation platform 31 and the pit can be covered by the pit flap 5. On the one hand, it can prevent debris from falling into it, and on the other hand, it can also share the load and prevent the rotating platform 21 or the translation platform 31 from tilting.

[0081] In one embodiment, the rotating drive mechanism 22 includes a hydraulic telescopic rod and a hydraulic cylinder; the telescopic end of the hydraulic telescopic rod is connected to the rotating platform; the hydraulic cylinder is connected to the hydraulic telescopic rod through a hydraulic oil circuit, and can hydraulically drive the hydraulic telescopic rod to extend or shorten; wherein, two hydraulic telescopic rods are centrally symmetrically arranged about the vertical center axis of the rotating platform 21, and the two hydraulic telescopic rods can be synchronously extended and retracted in opposite directions.

[0082] Specific, combined Figure 5 To further explain in detail, the rotating drive mechanism 22 is specifically configured as a hydraulic telescopic rod and a hydraulic oil pump, so that the hydraulic oil pump can accurately adjust the actual telescopic length of the hydraulic telescopic rod through the hydraulic oil circuit, thereby realizing precise angular drive control of the rotating platform 21, and both the hydraulic telescopic rod and the hydraulic oil pump also have good position self-locking performance. When the hydraulic oil pump controls the hydraulic telescopic rod to be extended to a specific length, the hydraulic telescopic rod can be stably maintained at this length under the hydraulic force, thereby realizing self-locking positioning of the accurate position of the rotating platform 21.

[0083] Moreover, two hydraulic telescopic rods are arranged in a centrally symmetrical manner about the vertical central axis of the rotating platform 21, and the two hydraulic telescopic rods can be synchronously extended and retracted in opposite directions. In this way, the two hydraulic telescopic rods can be synchronously extended and retracted under the drive of the hydraulic oil pump. In this way, the two hydraulic telescopic rods can apply driving force to the rotating platform in opposite directions, and at the same time extend to push, or shorten to pull the rotating platform 21 for angular driving, thereby further improving the stability and accuracy of the rotational drive of the rotating platform 21.

[0084] The specific configuration of the rotation drive mechanism 22 has the beneficial effects of being simple in structure and being able to stably realize the rotation drive of the rotating platform 21 .

[0085] Of course, the above-mentioned rotation drive mechanism 22 can also be configured as other forms of drive mechanisms, such as a "drive motor + lead screw nut" method, which can also realize the function of precise angular driving of the rotating platform 21.

[0086] In one embodiment, the translation drive mechanism 32 includes a hydraulic telescopic rod and a hydraulic cylinder; the telescopic end of the hydraulic telescopic rod is connected to the translation platform 31; the hydraulic cylinder is connected to the hydraulic telescopic rod through a hydraulic oil circuit, and can hydraulically drive the hydraulic telescopic rod to extend or shorten; wherein, two hydraulic telescopic rods are arranged at intervals on the same side of the translation platform 31, and the two hydraulic telescopic rods can be extended and retracted synchronously.

[0087] Specific, combined Figure 3 To further explain in detail, similarly, the translation drive mechanism 32 is specifically configured as a hydraulic telescopic rod and a hydraulic oil pump, so that the hydraulic oil pump can accurately adjust the actual telescopic length of the hydraulic telescopic rod through the hydraulic oil circuit, thereby realizing the drive control of the precise moving distance of the translation stage 31, and both the hydraulic telescopic rod and the hydraulic oil pump also have good position self-locking performance. When the hydraulic oil pump controls the hydraulic telescopic rod to be extended to a specific length, the hydraulic telescopic rod can be stably maintained at this length under the hydraulic force, thereby realizing the self-locking positioning of the accurate position of the translation stage 31.

[0088] Moreover, two hydraulic telescopic rods are arranged at intervals on the same side of the translation stage 31, and the two hydraulic telescopic rods can be retracted and retracted synchronously, and the two hydraulic telescopic rods can be retracted and retracted synchronously in the same direction. In this way, the two hydraulic telescopic rods can be retracted and retracted synchronously under the drive of the hydraulic oil pump, and at the same time extend to push, or shorten to pull the translation stage 31 for translation drive, further improving the stability and accuracy of the translation drive of the translation stage 31.
