[0022] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0023] like Figures 1 to 4The diagram illustrates a specific embodiment of the quick-connect structure between the launch vehicle and the launch pad provided in this example. It includes: a first connecting plate 101, a second connecting plate 201, a support block 3, a gap adjusting block 4, and an axial locking bolt 5. The first connecting plate 101 is connected to the launch vehicle 1, and the second connecting plate 201 is connected to the launch pad 2. The support block 3 is connected to both the first connecting plate 101 and the second connecting plate 201 via fasteners. The sides of both the first connecting plate 101 and the second connecting plate 201 have slots, and the support block 3 is horizontally embedded within these slots. This configuration allows the support block 3 to withstand the forces exerted by the launch vehicle 1 and the launch pad 2 in the height direction.
[0024] like Figure 1 , Figure 2 As shown, the gap adjustment block 4 is disposed between the first connecting plate 101 and the second connecting plate 201, and is used to adjust the gap between the first connecting plate 101 and the second connecting plate 201.
[0025] like Figure 1 , Figure 2 As shown, the axial locking bolt 5 passes through the first connecting plate 101 and the second connecting plate 201 respectively, and at least one end of the axial locking bolt 5 is connected to a nut. The axial locking bolt 5 is used to axially lock the launch vehicle 1 and the launch platform 2.
[0026] The quick connection structure between the launch vehicle and the launch pad provided in this embodiment can tolerate a large axial installation deviation between the launch vehicle 1 and the launch pad 2, and can quickly connect and disconnect the launch pad 2 and the launch vehicle 1 in the launch area without the aid of external auxiliary equipment.
[0027] like Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the longitudinal section of the support block 3 is a wedge-shaped structure, and the shape of the slot matches that of the support block 3. This design adds a guiding function, enabling rapid connection between the launch pad 2 and the launch vehicle 1, while ensuring the connection has a high load-bearing capacity, further improving product reliability. Of course, the above description is not limiting; in some alternative embodiments, the longitudinal section of the support block 3 can also adopt other structures, such as rectangular or circular.
[0028] like Figure 5 As shown, in some embodiments, the longitudinal section of the support block 3 is an isosceles trapezoid. Of course, the above description is not limiting; in some alternative embodiments, the wedge structure may also employ other structures, such as a right trapezoid.
[0029] like Figure 6 , Figure 7 As shown, in some embodiments, the gap adjusting block 4 has a housing 401, within which a movable block 402 slides. The housing 401 has a driving device for moving the movable block 402. At least one side of the movable block 402 extends out of the housing 401, and this protruding side is an inclined surface. During operation, the driving device drives the movable block 402 to move within the housing 401. The inclined surface of the movable block 402 contacts the first connecting plate 101 or the second connecting plate 201, thereby adjusting the axial distance between the first connecting plate 101 and the second connecting plate 201. This structure of the gap adjusting block 4 improves the accuracy of adjusting the axial distance between the first connecting plate 101 and the second connecting plate 201. Of course, the above description is not limiting. In some alternative embodiments, the gap adjusting block 4 can also adopt other structures, such as multiple adjusting blocks of different specifications.
[0030] like Figure 7 As shown, in some embodiments, the movable block 402 extends from both sides of the housing 401, and both sides are inclined surfaces, with both inclined surfaces tilting towards the center. With this configuration, the two inclined surfaces of the movable block 402 can be moved by friction through the drive device, thereby providing adjustable speed. Of course, the above description is not limiting; in some alternative embodiments, only one inclined surface may be present, while the other side may be a parallel surface.
[0031] like Figure 7 As shown, in some embodiments, the driving device is a screw 403, which passes through the housing 401 and is threadedly connected to the moving block 402; or the screw 403 is threadedly connected to the housing 401, passes through the housing 401, and is rotatably connected to the moving block 402. Both of these embodiments achieve the purpose of rotating the screw 403 to move the moving block 402. Of course, the above description is not limiting; in some alternative embodiments, the driving device can be other drives, such as an electric actuator.
[0032] like Figure 7 As shown, in some embodiments, the outer surface of the housing 401 has a locking nut 404 threadedly connected to the screw 403. After the position of the moving block 402 is adjusted to the correct position by the screw 403, the locking nut 404 can lock the position of the screw 403, thereby locking the gap adjustment.
[0033] like Figure 3 , Figure 4As shown, in some embodiments, the bottom of the groove has a threaded hole 6 for connecting bolts. With this threaded hole 6, when connecting the support block 3, the bolt passes through the support block 3 and connects to the threaded hole 6 at the bottom of the groove, thus connecting the support block 3 to the grooves of the first connecting plate 101 and the second connecting plate 201. Figure 5 As shown, it should be noted that in this embodiment, the support block 3 has a through hole 301 for passing a bolt. After the bolt passes through the through hole 301, it connects with the threaded hole 6 of the groove. At least one of the through holes 301 is a strip hole. With this setting, after the support block 3 is installed in the groove, the distance between the first connecting plate 101 and the second connecting plate 201 can still be adjusted. After the gap is adjusted, the support block 3 is locked.
[0034] like Figure 3 , Figure 4 As shown, in some embodiments, the first connecting plate 101 and the second connecting plate 201 each have through holes 7 for the axial locking bolt 5 to pass through. The through holes 7 allow the axial locking bolt 5 to pass through, thereby achieving axial locking of the first connecting plate 101 and the second connecting plate 201.
[0035] like Figure 1 As shown, the quick-connect structure between the launch vehicle and the launch pad provided in this embodiment has two symmetrically arranged sets. These two sets of connection structures ensure rapid connection between the launch vehicle 1 and the launch pad 2, as well as stability after connection. Of course, the above description is not limiting; in some alternative embodiments, the quick-connect structure between the launch vehicle and the launch pad may have more sets, such as four sets.
[0036] Working principle: When connecting the launch vehicle 1 to the launch pad 2, first ensure that the launch vehicle 1 and the launch pad 2 are in the right relative position, and prepare the necessary connection structure components, including: support block 3, gap adjustment block 4, axial locking bolt 5 and corresponding fasteners and tools.
[0037] The support block 3 is connected to the first connecting plate 101 and the second connecting plate 201 respectively using fasteners. Since the first connecting plate 101 and the second connecting plate 201 have slots on their sides, the support block 3 is horizontally embedded into the two slots. Note that the shape of the slots matches the support block 3, and the wedge-shaped structure can be used to guide and assist in quick connection.
[0038] Place the gap adjusting block 4 between the first connecting plate 101 and the second connecting plate 201. Move the moving block 402 by operating the drive device (rotating the screw 403). Use the inclined surface of the moving block 402 extending out of the outer shell 401 to adjust the gap between the first connecting plate 101 and the second connecting plate 201. After adjustment, tighten the locking nut 404 to fix the gap adjusting block 4.
[0039] The axial locking bolts 5 are passed through the through holes 7 on the first connecting plate 101 and the second connecting plate 201 respectively. A locking nut 404 is connected to one end of the axial locking bolts 5 and tightened to achieve axial locking of the launch vehicle 1 and the launch platform 2.
[0040] During disassembly, the operation is reversed: first, loosen the locking nut 404 of the axial locking bolt 5 and remove the axial locking bolt 5; then loosen the locking nut 404 of the gap adjusting block 4, reverse the operation of the drive device to return the moving block 402 to its original position, and remove the gap adjusting block 4; finally, remove the fasteners connecting the support block 3 to the first and second connecting plates, remove the support block 3, and complete the disassembly.
[0041] The quick connection structure between the launch vehicle and the launch pad provided in this embodiment has a support block 3 horizontally embedded in the slots on the sides of the first connecting plate 101 and the second connecting plate 201, and the longitudinal section can be a wedge-shaped structure. This connection method can withstand the forces exerted by the launch vehicle 1 and the launch pad 2 in the height direction. At the same time, the wedge-shaped support block 3 and the matching slot can realize the guiding function, assist the launch pad 2 and the launch vehicle 1 in quick connection, and ensure that the connection has a high load-bearing capacity.
[0042] A movable block 402 is slidably connected inside the outer shell 401 of the gap adjusting block 4. The movable block 402 is driven to move by a driving device (such as a screw 403). At least one side of the movable block 402 protrudes from the outer shell 401 as an inclined surface. The movement of the inclined surface changes the distance between the first connecting plate 101 and the second connecting plate 201, thereby adjusting the distance between them to adapt to different installation requirements and to meet the situation where there is a large axial installation deviation between the launch vehicle 1 and the launch pad 2.
[0043] The axial locking bolts 5 pass through the first connecting plate 101 and the second connecting plate 201 respectively. By connecting and tightening the locking nuts 404 at one or both ends of the axial locking bolts 5, the first connecting plate 101 and the second connecting plate 201 are tightly connected in the axial direction, thereby locking the launch vehicle 1 and the launch pad 2 in the axial direction and ensuring the stability and reliability of the connection between the two.
[0044] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the present invention.
