[0050] 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.

[0051] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0052] Combination Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the present disclosure provides a satellite-rocket assembly heavy-duty track vertical transfer translational single-part track conversion device, which includes a translation platform 1, a translation drive mechanism 2 and a liner rail assembly 3; the translation platform 1 is arranged at the track merger, and can reciprocate and translate in one direction; the translation drive mechanism 2 is connected to the translation platform 1 in transmission; the liner rail assembly 3 is supported on the lower side of the translation platform 1; wherein the translation drive mechanism 2 can drive the translation platform 1 to slide and translate along the liner rail assembly 3 to different positions; at least a change rail segment 11 is laid in the translation platform 1, and when the translation platform 1 is located at different positions, the change rail segment 11 can be connected with different tracks separately.

[0053] The satellite-rocket combination heavy-duty orbit vertical transfer and translational single-part orbit conversion device can be specifically but not limited to being used at the junction of the straight track and the curved track of the heavy-duty carrier track in the launch site of the space launch vehicle, and this is used as an example to illustrate.

[0054] When the satellite-rocket combination heavy-duty track vertical transfer translational single-section track conversion device is used, first a pit is dug at the intersection of the tracks, and the liner rail assembly 3 is laid on the bottom wall of the pit, and then the translation platform 1 is installed with a limit support above the liner rail assembly 3, and the track-changing track sections 11 laid in the translation platform 1 can be at the same horizontal height plane as the crossing tracks, and the translation drive mechanism 2 is connected to the translation platform 1 by transmission.

[0055] When the satellite-rocket combination heavy-duty track vertical transfer translational single-section track conversion device needs to convert the cross track, it only needs to drive the translation platform 1 to slide along the liner rail assembly 3 for a certain distance through the translation drive mechanism 2, so as to change the actual position of the track change segment 11 in the translation platform 1, so that the track change segment 11 can be switched and docked with the merged intersection of the straight track and the curved track, and the track change segment 11 can be docked with the straight track segment, or the curved track separately, thereby realizing the function of switching and transforming the actual guide path of the merged intersection of the straight track and the curved track.

[0056] Moreover, the satellite-rocket assembly heavy-duty orbit vertical transfer translation type single-division orbit conversion device provided in the embodiment of the present disclosure can be applied to Figure 1It can be used in scenarios such as the intersection of double tracks, the intersection of three tracks, and the intersection of four tracks. Especially when applied to the merged intersection of straight tracks and curved tracks in the heavy-duty carrier tracks in the launch site of a space carrier rocket, it can realize the rapid switching between the vertical assembly and test plants of multiple carrier rockets and different launch towers, greatly improving the flexibility of the transportation path and the diversity of transportation functions of the fixed-laid heavy-duty carrier tracks, so that the fixed-laid heavy-duty carrier tracks can meet the needs of heavier and more diverse launch missions, and significantly improve the economic benefits of the fixed-laid heavy-duty carrier tracks.

[0057] In summary, the satellite-rocket combination heavy-duty orbit vertical transfer and translational single-part orbit conversion device provided in the embodiments of the present disclosure has the ability to greatly improve the flexibility of orbital transportation paths, diversify transportation functions, realize flexible switching of guide paths at the merged intersection of straight rails and curved rails, and greatly improve the economic cost-effectiveness of fixed rail construction.

[0058] In one possible implementation manner, the track-changing rail segment 11 at least includes a straight track-changing rail segment 111 and a curved track-changing rail segment 112; the straight track-changing rail segment 111 is extended along the length direction of the translation stage 1; the curved track-changing rail segment 112 is correspondingly arranged along the length direction of the translation stage 1 as a whole, and is spaced correspondingly from the straight track-changing rail segment 111; when the translation stage 1 is located at the first position, the straight track-changing rail segment 111 is docked with the rail at the merging point; when the translation stage 1 is located at the second position, the curved track-changing rail segment 112 is docked with the rail at the merging point.

[0059] Specific, combined Figure 1 and Figure 2 To further explain in detail, at this time, the track-changing rail segment 11 is specifically configured as a straight track-changing rail segment 111 and a curved track-changing rail segment 112, and both of them are extended along the length direction of the translation stage 1 as a whole. In this way, when the translation stage 1 is driven by the translation drive mechanism 2 to reciprocate along its own width direction, the straight track-changing rail segment 111 and the curved track-changing rail segment 112 can be translated accordingly, so that the straight track-curved track merging intersection can be actually conducted through the straight track-curved track merging intersection respectively, thereby changing the actual guiding path of the guide rail at the intersection.

[0060] Of course, the track-changing track segment 11 can also be provided with more straight track-changing track segments 111 and more curved track-changing track segments 112 to be applicable to more complex straight track-curved track merging intersections.

[0061] The specific arrangement of the above-mentioned track-changing section 11 has a simple structure and can sensitively and quickly switch the actual guiding path of the guide rail at the intersection as the translation platform 1 reciprocates.

[0062] In one embodiment, one length side of the translation stage 1 is set to be a straight line, and the other relative length side is set to be an arc line; wherein the straight track change rail section 111 is set to correspond to the straight length side interval; the curved track change rail section 112 is set to correspond to the concentric interval of the arc length side.

[0063] Specific, combined Figure 1 and Figure 2 To further explain in detail, the two length sides of the translation stage 1 are respectively arranged to be straight and curved, and the straight line track section 111 is arranged at corresponding intervals with the straight line length side, and the curved track section 112 is arranged at corresponding concentric intervals with the curved length side. In this way, the shape structure of the translation stage 1 can be fully utilized to arrange the straight line track section 111 and the curved track section 112 according to the shape, and the curved length side and the straight line length side of the translation stage 1 can realize docking and installation reference when the translation stage 1 is moved to a preset position.

[0064] The specific arrangement of the above-mentioned translation platform 1 has the beneficial effects of being simple in structure and being able to utilize its own shape and structure to arrange the track-changing sections 11 in accordance with the shape.

[0065] In one embodiment, the satellite-rocket assembly heavy-duty orbit vertical transfer translational single-part orbit conversion device also includes an anti-overturning positioning mechanism 4; the anti-overturning positioning mechanism 4 is detachably arranged on the lower side of the translation platform 1, and is used to limit the connection between the translation platform 1 and the liner rail assembly 3.

[0066] Specific, combined Figure 3 and Figure 5 To further explain in detail, an anti-rollover positioning mechanism 4 is provided on the lower side of the translation stage 1 to be connected with the liner rail assembly 3 for limiting position. In this way, when the translation stage 1 is driven by the translation driving mechanism 2 to translate to the position where it is docked with the track, the anti-rollover positioning mechanism 4 can limit and fix the translation stage 1 to ensure the firmness of the docking between the switching rail section 11 in the translation stage 1 and the track. The anti-rollover positioning mechanism 4 can also limit the translation stage 1 for preventing overturning. In this way, when a heavy load is transported to the translation stage 1, the lateral force on one side of the translation stage 1 is prevented from being too large, which may cause the translation stage 1 to tilt or overturn.

[0067] The above-mentioned anti-overturning positioning mechanism 4 can be specifically set into a variety of structures, for example, it can be set as a supporting anti-overturning positioning rod similar to a hydraulic jack structure to respectively perform anti-overturning support and limit the side of the translation platform 1, or it can be set as a compression elastic positioning member similar to a spring sheet structure to respectively perform anti-overturning support and limit the side of the translation platform 1.

[0068] 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 corresponding pin holes in the translation stage 1 and the liner rail assembly 3; the anti-overturning hook 42 can be detachably hooked and hung between the translation stage 1 and the liner rail assembly 3; wherein, the positioning pin 41 and the anti-overturning hook 42 are respectively distributed in plurality along the length direction of the translation stage 1.

[0069] 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 43, and the positioning pin 41 can be detachably inserted into the corresponding pin holes in the translation stage 1 and the liner rail assembly 3, and the relative positioning and limiting function of the translation stage 1 and the liner rail assembly 3 can be achieved by manually installing the positioning pin 41; the anti-overturning hook 43 can be detachably hooked and hung between the translation stage 1 and the liner rail assembly 3, which can further improve the anti-overturning reliability between the translation stage 1 and the liner rail assembly 3.

[0070] 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 translation platform 1, fully ensuring the safety and reliability of the heavy-duty orbit vertical transfer translational single-part orbit conversion device of the satellite-rocket combination during heavy-duty operation.

[0071] In one embodiment, the rail assembly 3 includes a plurality of rail strips 31 extending along the moving direction of the translation stage 1; the rail strips 31 each have a rolling body abutting against the translation stage 1; and the plurality of rail strips 31 are arranged parallel to each other and spaced apart.

[0072] Specific, combined Figure 2 To further explain in detail, the rail assembly 3 is specifically configured to be a plurality of concentrically arranged strip rail members 31, and each strip rail member 31 has a rolling body that abuts and supports the translation stage 1, and the plurality of strip rail members 31 extend along the width direction of the translation stage 1 and are arranged parallel to each other at intervals. In this way, when the translation stage 1 is relatively translated along the rail assembly 3, the rotation direction of the translation stage 1 can abut against the plurality of strip rail members 31 at the same time, and the rolling bodies in the strip rail members 31 can greatly reduce the friction resistance between the translation stage 1 and the rail assembly 3, thereby fully improving the smoothness of the translation stage 1 during translation and sliding.

[0073] Furthermore, the rolling elements in the strip rail member 31 may be, but are not limited to, spherical balls or cylindrical needles, and are embedded in the side of the strip rail member 31 facing the translation platform 1 .

[0074] The specific arrangement of the liner rail assembly 3 has the beneficial effects of simple structure, being able to stably support the translation of the translation stage 1, and reducing the friction resistance when the translation stage 1 moves.

[0075] In one possible implementation manner, the satellite-rocket assembly heavy-duty orbit vertical transfer translational single-part orbit conversion device also includes a guide wheel group 32; the guide wheel group 32 is arranged between the liner rail assembly 3 and the translation platform 1, and is used to guide and support the movement of the translation platform 1.

[0076] Specific, combined Figure 6 To further explain in detail, a guide wheel group 32 is further arranged between the liner rail assembly 3 and the translation stage 1. In addition to being able to support the translation stage 1 together with the liner rail assembly 3, the guide wheel group 32 can also guide and limit the moving direction of the translation stage 1, thereby fully ensuring the accuracy of the displacement direction of the translation stage 1 when the translation drive mechanism 2 drives it.

[0077] In one possible implementation manner, the satellite-rocket assembly heavy-duty orbit vertical transfer translational single-part orbit conversion device also includes a pit flap 5; the pit flap 5 is arranged on the length side of the translation platform 1, and can be stored and folded toward the translation platform 1, or folded and extended away from the translation platform 1; and when the pit flap 5 is folded and extended away from the translation platform 1, it can cover the gap formed by the translation platform 1 and the pit.

[0078] Specific, combined Figure 4 To further explain in detail, the star-rocket combination heavy-duty orbit vertical transfer translational single-part orbit conversion device also includes a pit flap 5 arranged on the length side of the translation platform 1, and the pit flap 5 can be stored and folded toward the translation platform 1, or folded and extended away from the translation platform 1, so that when the translation platform 1 slides and translates to adjust the position, the pit flap 5 can be stored and folded toward the translation platform 1 to avoid the pit flap 5 interfering with the normal movement of the translation platform 1; when the translation platform 1 completes the sliding and translation, the pit flap 5 can be folded and extended away from the translation platform 1, and the gap between the translation platform 1 and the pit can be covered by the pit flap 5, which can prevent debris from falling into it on the one hand, and can also share the load and prevent the translation platform 1 from tilting to a certain extent on the other hand.

[0079] In one embodiment, the translation drive mechanism 2 includes a hydraulic telescopic rod 21 and a hydraulic cylinder 22; the telescopic end of the hydraulic telescopic rod 21 is connected to the translation platform 1; the hydraulic cylinder 22 is connected to the hydraulic telescopic rod 21 through a hydraulic oil circuit, and can hydraulically drive the hydraulic telescopic rod 21 to extend or shorten.

[0080] Specific, combined Figure 4To further explain in detail, the translation drive mechanism 2 is specifically configured as a hydraulic telescopic rod 21 and a hydraulic cylinder 22, so that the hydraulic cylinder 22 can accurately adjust the actual telescopic length of the hydraulic telescopic rod 21 through the hydraulic oil circuit, thereby realizing the precise translational sliding distance of the translation platform 1, and the hydraulic telescopic rod 21 and the hydraulic cylinder 22 both have good position self-locking performance. When the hydraulic cylinder 22 controls the hydraulic telescopic rod 21 to be extended to a specific length, the hydraulic telescopic rod 21 can be stably maintained at the length under the hydraulic force, thereby realizing the self-locking positioning of the translation position of the translation platform 1.

[0081] The specific configuration of the above-mentioned translation drive mechanism 2 has the beneficial effects of being simple in structure and being able to stabilize itself to achieve translational drive of the translation stage 1 .

[0082] Of course, the above-mentioned translation drive mechanism 2 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 translation stage 1.

[0083] In one possible implementation manner, two hydraulic telescopic rods 21 are disposed at intervals on the same side of the translation platform 1 ; and the two hydraulic telescopic rods 21 can be telescoped synchronously.

[0084] Specific, combined Figure 1 and Figure 4 To further explain in detail, two hydraulic telescopic rods 21 are arranged at intervals on the same side, and the two hydraulic telescopic rods 21 can be synchronously extended and retracted in the same direction, so that the two hydraulic telescopic rods 21 can be synchronously extended and retracted under the drive of the hydraulic cylinder 22, and the two hydraulic telescopic rods 21 can simultaneously apply driving forces of the same magnitude to the translation stage 1 in the same direction, and simultaneously extend and push, or shorten and pull the translation stage 1 to slide in translation, thereby further improving the stability and accuracy of the translation drive of the translation stage 1.

[0085] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present disclosure, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0086] The above is only a specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure.
