[0076] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. Numerous specific details are set forth in the following detailed description to provide a comprehensive understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without requiring some of these specific details. The following description of embodiments is merely intended to provide a better understanding of this utility model by illustrating examples of it. In the accompanying drawings and the following description, at least some well-known structures and techniques have not been shown to avoid unnecessarily obscuring the utility model; and, for clarity, the dimensions of some structures may be exaggerated. Furthermore, the features, structures, or characteristics described below can be combined in any suitable manner in one or more embodiments.
[0077] like Figures 1 to 10 As shown, a rocket engine transfer and assembly integrated universal adjustment platform includes a platform structure 1 and several support leg structures 2 disposed on the platform structure 1. The support leg structures 2 are distributed on both sides of the platform structure 1, and can be adjusted in height and parallelism by finding suitable support points. In this embodiment, the platform structure 1 includes a walking component 11, a rotation and lifting component 12, and a translation component 13. In practical applications, the components of the platform structure 1 can be circular or other common shapes; in this embodiment, they are circular to facilitate rotation and adjustment operations.
[0078] like Figure 1 As shown, during processing and assembly, the support leg structure 2 is located on the side of the walking assembly 11; the rotary lifting assembly 12 is located directly above the walking assembly 11 and is used for the rotary lifting adjustment drive of the translation assembly 13; the translation assembly 13 is located directly above the rotary lifting assembly 12 and is used for the translation adjustment drive of the rocket motor. Through the above structure, the lifting, translation, and adjustment operations of the overall structure can be realized, which is beneficial for meeting the usage requirements of different situations.
[0079] like Figure 2 and Figure 3 As shown, the rotary lifting assembly 12 includes a support base plate 121, several screw jacks 122, several reversing shafts 123, a lifting servo motor 124, a rotation motor 125, a rotation drive gear 126, a master servo commutator 127, and several slave servo commutators 128. The screw jacks 122, the master servo commutator 127, and the slave servo commutators 128 are all conventional structures in the prior art, and are simply applied.
[0080] During assembly, the support base plate 121 is fixed to the lifting flanges of several screw jacks 122. The movement of the screw jacks 122 drives the support base plate 121 to rise and fall. The screw jacks 122 are respectively connected to several slave servo commutators 128 through reversing shafts 123. The slave servo commutators 128 are connected to the master servo commutator 127 through reversing shafts 123. The lifting servo motor 124 is connected to the master servo commutator 127 and is used for the lifting drive of the screw jacks 122. The rotary motor 125 is fixed on the support base plate 121, and the rotary drive gear 126 is fixed on the main shaft of the rotary motor 125. The rotary motor 125 is connected to the translation assembly 13 through the rotary drive gear 126 and is used for the rotation adjustment of the translation assembly 13.
[0081] Furthermore, in this embodiment, there are four screw jacks 122 and two slave servo commutators 128; the four screw jacks 122 are connected to the two slave servo commutators 128 via commutator shafts 123. The lifting servo motor 124, in conjunction with the master servo commutator 127 and the slave servo commutators 128, enables synchronous lifting of the screw jacks 122, ensuring the synchronicity and effectiveness of the lifting, thus achieving the overall lifting action of the translation component 13. Simultaneously, the rotational motor 125, in conjunction with the rotational drive gear 126, enables the overall rotational action of the translation component 13. The rotational motor 125 provides the power source, driving the rotational driven gear 133. Since the rotational driven gear 133 is fixed on the lower base plate 132, the overall rotational action of the translation component 13 can be achieved.
[0082] Furthermore, in practical applications, the edge of the support base plate 121 is also welded and fixed with a skirt to protect the internal structure, improve the overall aesthetics, reduce the number of operators required when docking the rocket engine with the test stand, and also solve the technical shortcomings of the rocket engine being difficult and time-consuming to assemble on a vertical test stand.
[0083] like Figure 4 and Figure 5 As shown, in this embodiment, the translation component 13 includes an upper top plate 131, a lower bottom plate 132, a rotary driven gear 133, a connecting shaft 134, and a translation drive structure 135. During assembly, the center of the lower bottom plate 132 is rotatably connected to the center of the top surface of the rotary lifting component 12 via the connecting shaft 134. The rotary driven gear 133 is fixed in the middle of the bottom surface of the lower bottom plate 132 and is concentrically arranged with the connecting shaft 134. The rotary driven gear 133 meshes with the rotary drive gear 126 to achieve rotary drive. The translation drive structure 135 is fixed on the top surface of the lower bottom plate 132, and the upper top plate 131 is connected to the translation drive structure 135. The translation drive structure 135 drives the upper top plate 131 to translate on the top surface of the lower bottom plate 132.
[0084] Meanwhile, the translation drive structure 135 includes a guide rail 1351, a slider 1352, a drive block 1353, a translation control motor 1354, and a translation ball screw 1355; the guide rail 1351 is fixed to the top surface of the lower base plate 132; the slider 1352 is translatably mounted on the guide rail 1351, the drive block 1353 is helically connected to the translation ball screw 1355, and both the slider 1352 and the drive block 1353 are fixedly connected to the bottom surface of the upper top plate 131; the translation control motor 1354 is fixed to the top surface of the lower base plate 132, and the translation ball screw 1355 is fixed to the main shaft of the translation control motor 1354 through a coupling.
[0085] In this embodiment, the diameter of the driven rotary gear 133 is larger than the diameter of the driven rotary gear 126, and the translational drive structure 135 converts rotational force into linear motion, realizing the linear translation of the upper top plate 131. Through the above structure, the effectiveness and stability of the translation can also be guaranteed. In practical applications, the edge of the lower bottom plate 132 is also welded and fixed with a skirt to protect the internal structure and improve the overall aesthetic appearance.
[0086] Furthermore, in practical applications, a plurality of universal balls 3 are evenly arranged along the bottom edge of the lower base plate 132; the bottom of the universal balls 3 are rolled onto the top surface of the supporting base plate 121. These universal balls 3 not only facilitate support and rotation, but also, through the aforementioned structure, ensure smooth rotation of the lower base plate 132 on the supporting base plate 121, guaranteeing the effectiveness and reliability of the rotation. Simultaneously, an oil-free bushing 4 is provided at the connection between the connecting shaft 134 and the supporting base plate 121 of the rotating lifting assembly 12. This oil-free bushing 4 is made of tin bronze, ensuring smooth and unobstructed rotation.
[0087] like Figure 6 , Figure 8 As shown, the walking assembly 11 includes a walking seat 111, a walking drive wheel assembly 112, a walking driven wheel assembly 113, and a connecting member 114; the walking seat 111 is provided with a through groove 5.
[0088] During assembly, the driving wheel assembly 112 and the driven wheel assembly 113 are both located on the top surface of the travel seat 111, and the driving wheel assembly 112 and the driven wheel assembly 113 are connected by a connector 114; the wheel edges of the driving wheel assembly 112 and the driven wheel assembly 113 pass through the through groove 5 and extend out of the bottom surface of the travel seat 111; the rotary lifting assembly 12 includes a plurality of screw jacks 122, the bottom end of which is fixed on the travel seat 111.
[0089] The driving drive wheel assembly 112 includes a wheel 1121, a driving drive motor 1122, a steering motor 1123, a driving main gear 1124, a driving transmission gear 1125, a steering gear 1126, a transmission chain 1127, a crank 1128, a sector gear 1129, a steering drive gear 11210, and a connecting rod 11211. The wheel 1121 is connected to the driving transmission gear 1125 through the crank 1128, and the driving drive motor 1122 meshes with the driving transmission gear 1125 through the driving main gear 1124.
[0090] The steering drive gear 11210 is fixed on the main shaft of the steering motor 1123. The transmission gear chain 1127 is connected between the steering drive gear 11210 and the steering gear 1126, and the steering gear 1126 meshes with the sector gear 1129. The sector gear 1129 is connected to the crank 1128. The steering drive gear 11210 drives the sector gear 1129 to rotate and realizes the steering adjustment of the crank 1128. The two ends of the connecting rod 11211 are connected between the two cranks 1128, so that the two cranks 1128 turn synchronously.
[0091] The above structure ensures the effectiveness and reliability of the walking drive, effectively realizes the transfer operation, and also enables effective steering adjustment and control. Both the main walking gear 1124 and the walking transmission gear 1125 are bevel gears.
[0092] like Figure 9 , Figure 10 As shown, the support leg structure 2 includes a large arm 21, a small arm 22, a lifting cylinder 23, and a telescopic cylinder 24. The small arm 22 is telescopically disposed within the telescopic cavities at both ends of the large arm 21, and the telescopic cylinder 24 is fixed between the telescopic cavities of the small arm 22 and the large arm 21. The rotating lifting assembly 12 includes a support base plate 121, the large arm 21 is fixed on the support base plate 121, and the lifting cylinder 23 is fixed at the end of the small arm 22 extending out of the support base plate 121 for adjusting the lifting of the support base plate 121. Guide rollers 6 are provided between the telescopic cavities of the small arm 22 and the large arm 21; and foot pads 7 are fixed to the bottom surface of the end of the small arm 22 extending out of the support base plate 121.
[0093] In this embodiment, the above structure allows for adjustment of different positions via the telescopic electric cylinder 24 to ensure the search for a suitable support point. It also allows for lifting adjustment via the lifting electric cylinder 23. There are four lifting electric cylinders 23, each set individually, meaning that the corresponding height can be set individually. In cases of uneven ground, this helps to ensure the parallelism of the mating surfaces between the engine and the test bench thrust frame, improving the accuracy and effectiveness of the assembly.
[0094] The above technical solution has the following beneficial effects:
