Description

Technical Field

[0001] This invention relates to the field of rocket launch technology, specifically to a rocket vertical support leveling system and a rocket vertical support leveling method. Background Technology

[0002] Verticality adjustment of liquid rockets is a measure to adjust the initial attitude of the rocket and ensure the safety of takeoff and the accuracy of flight.

[0003] In existing technology, after the rocket is erected, it is supported by the lower clamp mechanism of the launch pad. The tail end of the rocket needs to be docked with the launch pad. A lifting device is installed on the launch pad. The lifting device rises a certain distance and is adjusted to the set load state by the load monitoring system of the lifting system, so as to release the load of the lower clamp pin and disassemble the lower clamp, so that the rocket can be supported by the lifting device. The lifting device coordinates the adjustment of the four outriggers to ensure that the verticality of the rocket meets the design specifications.

[0004] However, the four outriggers of the conventional lifting device are connected to the rocket docking surface at a single point. During the leveling process, the adjustment accuracy of the actuators is required to be high. The deviation between the four actuators makes the leveling process complicated. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the problem that the mutual adjustment of the four actuators of the lifting device in the existing rocket support and leveling system is deviated, resulting in a complicated process flow, thereby providing a rocket vertical support and leveling system and a rocket vertical support and leveling method.

[0006] To solve the above-mentioned technical problems, the present invention provides a rocket vertical support and leveling system, comprising: a launch platform, a lifting device, and a support tray. The lifting device is disposed on the launch platform, and multiple lifting devices are evenly arranged on the launch platform along the circumferential direction. The support tray is disposed on the top of the lifting device, and the support tray is ball-jointed to the lifting device. The support tray is movably and vertically disposed on the launch platform through the lifting device, and the support tray is used to support the rocket.

[0007] In operation, multiple lifting devices on the launch pad pre-level the support tray through a combination of coordinated and individual adjustments. Once the rocket is erected, the lifting devices operate synchronously, raising and lowering the support tray as a whole until it is firmly aligned with the rocket's docking surface. Fine adjustments are then made to vertically level the rocket, ensuring a stable reference point for the docking surface between the support tray and the rocket. Leveling can be achieved in a single operation, making the process efficient and reliable. The rocket vertical support leveling system provided by this invention solves the problem of complex processes caused by misalignment in the four actuators of the lifting devices in existing rocket support leveling systems.

[0008] Optionally, the support tray is provided with multiple adjustable fine-tuning mechanisms evenly distributed along its circumference. These mechanisms compensate for localized deformation at the rocket's tail end and dimensional deviations caused by manufacturing processes, resulting from the pulling action of the lower clamps after the rocket is erected.

[0009] Optionally, the fine-tuning mechanism includes: a first lead screw threadedly connected to the support tray; and a docking part disposed at the top of the first lead screw, the top of which is used to dock with the rocket body. The docking part has an operating space, and the top of the operating space has a docking hole for installing a windproof bolt. With the above configuration, the first lead screw is threadedly connected to the support tray, and can be adjusted by hand-cranking a wrench to ensure that the upper surface of the docking part is pressed against the docking surface of the rocket, allowing the windproof bolt to be locked into the docking hole within the operating space of the docking part.

[0010] Optionally, an adjusting shim is provided at the mating hole. This adjustment shim compensates for assembly misalignment between the windproof bolt and the mating hole, serving a transitional function.

[0011] Optionally, the docking part and the first lead screw are connected by a ball joint hinge. With this configuration, the ball joint hinge between the docking part and the first lead screw can accommodate local deformation at the rocket's tail end and dimensional deviations caused by manufacturing processes.

[0012] Optionally, multiple liftable limiting mechanisms are evenly arranged along the circumference of the launch pad, with the top of each limiting mechanism abutting against the bottom of the support tray. This arrangement allows the limiting mechanisms to support the rocket and provide mechanical restraint in the event of a lifting device failure. Furthermore, the limiting mechanisms dock with the support tray at the docking point, concentrating the overall load at the docking position of the fine-tuning mechanism on the support tray. This eliminates the need for additional interface designs, reducing the number of interfaces on the rocket and lowering the rigidity requirements.

[0013] Optionally, the limiting mechanism includes: a support, disposed on the launch pad; a second lead screw, threadedly connected to the support; and a mating block, disposed at the top of the second lead screw, the mating block being used to abut against the bottom of the support tray. With the above configuration, the second lead screw is threadedly connected to the support, and can be adjusted by hand-cranking a wrench to ensure the upper surface of the mating block is tightly against the bottom surface of the support tray. The limiting mechanism is manually operated, and the entire structure is supported by the rocket's own weight. The structure only bears axial pressure, without additional bending moment. Moreover, before rocket launch, the limiting mechanism does not require electric operation or automatic extension / retraction, resulting in high system reliability and reduced system failure risk.

[0014] Optionally, the docking block and the second lead screw are connected by a spherical hinge. The docking block is configured as a wedge-shaped block, and the bottom of the support tray is provided with a wedge-shaped surface for abutting against the wedge-shaped block. With the above configuration, when the position of the support tray changes after the rocket is leveled, the docking block and the wedge-shaped surface of the support tray can automatically align and fit together through the spherical hinge connection between the docking block and the second lead screw.

[0015] Optionally, the support tray is equipped with a level and a tilt sensor. These features assist in pre-leveling the support tray.

[0016] This invention provides a rocket vertical support leveling method, employing the rocket vertical support leveling system described in any of the above-mentioned schemes, comprising the following steps: Pre-leveling: Control the lifting device to level the support tray and stop the support tray in the designated position; The rocket body is supported and erected in place. The lifting device rises synchronously, driving the support tray to rise to the docking surface with the rocket. Unload the internal force of the lower clamps, and the lifting device rises synchronously. After the load test is qualified, unload the lower clamps on both sides of the rocket. The rocket body is vertically adjusted using a fine-tuning lifting device, which works in conjunction with the rocket tilt detection system to complete the vertical adjustment operation.

[0017] Because of the adoption of the above-mentioned rocket vertical support leveling system, it has any of the above advantages.

[0018] Optionally, after the rocket is erected and positioned, a 50mm gap is reserved between the rocket's docking surface and the upper end face of the fine-tuning mechanism on the support tray. The first lead screw of the fine-tuning mechanism is manually adjusted so that the docking part of the fine-tuning mechanism rises and fits tightly against the rocket's docking surface. Through the above setting, the fine-tuning mechanism is used to compensate for the local deformation of the rocket's tail end and the dimensional deviations caused by manufacturing under the pulling action of the lower clamp after the rocket is erected.

[0019] Optionally, after the fine-tuning mechanism is tightened, a 0.1mm feeler gauge is used to randomly check the docking gap at 8 points around the circumference of each docking surface between the fine-tuning mechanism and the rocket. If none of the gauges are inserted, the requirement is met. This setup ensures the stability of the rocket support by checking whether the docking gap meets the requirements.

[0020] Optionally, after the rocket's vertical adjustment operation is completed, the second lead screw of the manual limiting mechanism is cranked to bring the mating block of the limiting mechanism into contact with the wedge-shaped surface at the bottom of the support tray. Through this configuration, the limiting mechanism can provide mechanical support and limit the support tray in the event of a lifting device failure. Attached Figure Description

[0027] 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.

[0028] This embodiment provides a structure for a rocket vertical support leveling system that enables efficient and reliable process flow, used for rocket 7 vertical support leveling.

[0029] like Figure 1 The image shows a specific implementation of a rocket vertical support and leveling system provided in this embodiment, comprising: a launch pad 1, a lifting device 2, and a support tray 3. The lifting device 2 is disposed on the launch pad 1, and multiple lifting devices 2 are evenly arranged along the circumferential direction on the launch pad 1. The support tray 3 is disposed on the top of the lifting device 2, and the support tray 3 is ball-jointed to the lifting device 2. The support tray 3 is movably and vertically disposed on the launch pad 1 through the lifting device 2, and the support tray 3 is used to support the rocket 7.

[0030] In use, the multiple lifting devices 2 on the launch pad 1 are pre-leveled on the support tray 3 through a combined adjustment and single-adjustment control method. Once the rocket 7 is erected, the multiple lifting devices 2 operate synchronously, causing the support tray 3 to rise and fall as a whole, tightening with the docking surface of the rocket 7. Fine adjustments are then made to vertically level the rocket 7. The docking end face of the support tray 3 and the rocket 7 has a stable reference, requiring only one leveling operation. The process is efficient and reliable. The rocket vertical support leveling system provided in this embodiment solves the problem of complex processes caused by misalignment in the mutual adjustment of the four actuators of the lifting devices 2 in existing rocket 7 support leveling systems.

[0031] Specifically, such as Figure 1 , Figure 2 As shown, in the rocket vertical support leveling system provided in this embodiment, the lifting device 2 is set as a hydraulic system. The oil cylinder and pump station of the hydraulic system are installed inside the launch pad 1. After the lifting is in place, the exposed part of the oil cylinder piston is wrapped with fireproof fiberglass cloth, and fireproof mud is applied to the gap between the oil cylinder piston and the launch pad 1. When the rocket 7 takes off, the entire hydraulic system is thermally protected.

[0032] Specifically, such as Figure 1 As shown, in the rocket vertical support and leveling system provided in this embodiment, the lifting device 2 has four evenly arranged along the circumference, so that the support tray 3 forms a four-point support and leveling configuration. Alternatively, as an alternative implementation, the number of lifting devices 2 can be set to three or more, depending on design requirements.

[0033] It should be noted that the launch pad 1 is used for the fixed installation of the lifting device 2, product thermal protection, and rocket exhaust flow deflection.

[0034] like Figure 1 , Figure 2 As shown, in the rocket vertical support and leveling system provided in this embodiment, multiple liftable fine-tuning mechanisms 4 are evenly arranged circumferentially on the support tray 3. The fine-tuning mechanisms 4 are used to compensate for local deformation of the tail end of the rocket 7 and dimensional deviations caused by manufacturing processes under the pulling action of the lower clamp after the rocket 7 is erected. Alternatively, as an alternative implementation, the fine-tuning mechanisms 4 can be omitted, and the support tray 3 can be directly connected to the rocket 7.

[0035] Specifically, four fine-tuning mechanisms 4 are evenly arranged along the circumference of the support tray 3. Alternatively, as an alternative implementation, the number of fine-tuning mechanisms 4 can be set to three or more, depending on design requirements.

[0036] like Figure 2 , Figure 3 As shown, in the rocket vertical support leveling system provided in this embodiment, the fine-tuning mechanism 4 includes: a first lead screw 41, threadedly connected to the support tray 3; and a docking part 42, disposed at the top of the first lead screw 41. The top of the docking part 42 is used to dock with the rocket body. An operating space is provided within the docking part 42, and a docking hole is provided at the top of the operating space for installing a windproof bolt. The first lead screw 41 is threadedly connected to the support tray 3 and can be adjusted by hand-cranking a wrench to press the upper end face of the docking part 42 against the docking surface of the rocket 7. The windproof bolt is then locked into the docking hole within the operating space of the docking part 42. Alternatively, as an alternative implementation, the first lead screw 41 can be omitted, and an electric drive device can be provided on the support tray 3 to drive the docking part 42 to rise and fall.

[0037] Specifically, the docking part 42 is provided with an operating hole that communicates with the operating space.

[0038] like Figure 3 As shown, in the rocket vertical support leveling system provided in this embodiment, an adjusting washer 43 is provided at the docking hole. The adjusting washer is used to compensate for the assembly deviation between the windproof bolt and the docking hole, and plays a transition role.

[0039] like Figure 3 As shown, in the rocket vertical support leveling system provided in this embodiment, the docking part 42 and the first lead screw 41 are connected by a ball joint hinge. The ball joint hinge between the docking part 42 and the first lead screw 41 can accommodate local deformation at the tail end of the rocket 7 and dimensional deviations caused by manufacturing. Alternatively, as an alternative implementation, the docking part 42 and the first lead screw 41 can also be fixedly connected.

[0040] like Figure 1 , Figure 2 , Figure 4 As shown, in the rocket vertical support and leveling system provided in this embodiment, multiple liftable limiting mechanisms 5 are evenly arranged along the circumferential direction on the launch pad 1. The top of the limiting mechanism 5 is used to abut against the bottom of the support tray 3. When the lifting device 2 fails, the limiting mechanism 5 can support the rocket 7, playing a mechanical limiting role. Furthermore, the limiting mechanism 5 docks with the support tray 3, with the docking point located on the support tray 3. The overall load is concentrated at the docking position of the fine-tuning mechanism 4 on the support tray 3, eliminating the need for additional interface design, reducing the interface design on the rocket 7, and lowering the rigidity requirements of the rocket 7. Alternatively, as an alternative implementation, the top of the limiting mechanism 5 can also be used to abut against the docking surface of the rocket 7.

[0041] Specifically, the limiting mechanism 5 and the lifting device 2 are alternately arranged along the circumference of the support tray 3.

[0042] like Figure 4 , Figure 5 As shown, in the rocket vertical support leveling system provided in this embodiment, the limiting mechanism 5 includes: a support 51, disposed on the launch pad 1; a second lead screw 52, ​​threadedly connected to the support 51; and a docking block 53, disposed at the top of the second lead screw 52, ​​the docking block 53 being used to abut against the bottom of the support tray 3. The second lead screw 52 is threadedly connected to the support 51 and can be adjusted by hand-cranking a wrench to make the upper end face of the docking block 53 press tightly against the bottom face of the support tray 3. The limiting mechanism 5 is manually operated, and the entire structure is supported by the weight of the rocket 7. The structure only bears axial pressure and has no additional bending moment. Moreover, before the rocket 7 is launched, the limiting mechanism 5 does not require electric operation and has no automatic extension or retraction action, resulting in high system reliability and reducing the risk of system failure. In addition, as an alternative implementation, the first lead screw 41 is omitted, and an electric drive device is provided between the base and the docking block 53 to drive the docking block 53 to rise and fall.

[0043] like Figure 4 , Figure 5As shown, in the rocket vertical support leveling system provided in this embodiment, the docking block 53 is spherically hinged to the second lead screw 52. The docking block 53 is configured as a wedge-shaped block, and the bottom of the support tray 3 is provided with a wedge-shaped surface 6 for abutting against the wedge block. When the rocket 7 is leveled, the position of the support tray 3 changes. Through the spherical hinge connection between the docking block 53 and the second lead screw 52, ​​the docking block 53 and the wedge-shaped surface 6 of the support tray 3 can automatically align and fit together.

[0044] like Figure 1 As shown, in the rocket vertical support leveling system provided in this embodiment, the support tray 3 is equipped with a level and an inclination sensor. The level and the inclination sensor can assist the support tray 3 in pre-leveling.

[0045] How to use: like Figure 1 As shown, in this embodiment, the rocket vertical support leveling system uses multiple lifting devices 2 on the launch pad 1 to pre-level the support tray 3 through a combined adjustment and single adjustment control method. When the rocket 7 is erected, the multiple lifting devices 2 operate synchronously, and the support tray 3 is raised and lowered as a whole. The first lead screw 41 of the fine-tuning mechanism 4 is adjusted by hand-cranking the wrench to make the docking part 42 and the docking surface of the rocket 7 fit together. The lifting device 2 performs fine-tuning to level the rocket 7 vertically. The second lead screw 52 of the limiting mechanism 5 is adjusted by hand-cranking to make the docking block 53 fit together with the support tray 3. When the lifting device 2 fails, mechanical support limiting is achieved.

[0046] In addition, this embodiment also provides a rocket vertical support leveling method, which adopts the rocket vertical support leveling system described in the above embodiments, and includes the following steps: Pre-leveling: Control the lifting device 2 to level the support tray 3 and stop the support tray 3 in the designated position; The rocket body is supported and the rocket 7 is erected in place. The lifting device 2 rises synchronously, driving the support tray 3 to rise and dock with the rocket 7. Unload the internal force of the lower clamps, and the lifting device 2 rises synchronously. After the load test is qualified, unload the lower clamps on both sides of the rocket 7. The rocket body is vertically adjusted by fine-tuning the lifting device 2, which, in conjunction with the rocket 7 tilt detection system, completes the vertical adjustment operation of the rocket 7.

[0047] In use, the lifting device 2 adopts a combined adjustment and single adjustment control method to ensure that the support tray 3 is positioned according to the design specifications and pre-leveled. The tail end of the rocket 7 is connected to the erector frame by two symmetrical sets of lower clamps. After the rocket 7 is erected, it docks with the launch pad 1. After the rocket 7 is in place, the lifting device 2 rises synchronously to dock the support tray 3 with the rocket 7. The lifting device 2 continues to rise synchronously. After the load test is qualified, the lower clamps on both sides of the rocket 7 are unloaded, and the lifting device 2 is finely adjusted. In conjunction with the rocket 7 tilt angle detection system, the vertical adjustment operation of the rocket 7 is completed.

[0048] Specifically, when unloading the clamps, each of the lifting devices 2 is loaded with an additional 0.5t ± 0.1t.

[0049] In this embodiment, after the rocket 7 is erected and positioned, a 50mm gap is reserved between the docking surface of the rocket 7 and the upper end face of the fine-tuning mechanism 4 on the support tray 3. The first lead screw 41 of the fine-tuning mechanism 4 is manually adjusted so that the docking part 42 of the fine-tuning mechanism 4 rises and is tightly attached to the docking surface of the rocket 7. The fine-tuning mechanism 4 compensates for the local deformation of the tail end of the rocket 7 and the dimensional deviations caused by manufacturing under the pulling action of the lower clamp after the rocket 7 is erected.

[0050] In this embodiment, the rocket vertical support leveling method involves tightening the fine-tuning mechanism 4 by hand. Then, a 0.1mm feeler gauge is used to randomly check the docking gap at eight points around the circumference of each docking surface between the fine-tuning mechanism 4 and the rocket 7. If no feeler gauge is inserted, the requirement is met. Checking the docking gap ensures the stability of the support for the rocket 7.

[0051] In this embodiment, after the vertical adjustment of the rocket 7 is completed, the second lead screw 52 of the limiting mechanism 5 is manually cranked to make the connecting block 53 of the limiting mechanism 5 press against the wedge-shaped surface 6 at the bottom of the support tray 3. When the lifting device 2 fails, the limiting mechanism 5 can provide mechanical support and limit the support tray 3.

[0052] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
