Description

Technical Field

[0001] The present application relates to the field of rocket stabilization technology, and in particular to a shock absorbing and anti-rebound mechanism. Background Art

[0002] Currently, sea-based rocket launches have become an important method, offering greater planning flexibility and safer geographical applicability than land-based launches, and relatively mature and stable offshore launch platforms. However, sea launch conditions are affected by sea conditions and climate. The uncertainty of sea waves causes the ship's hull to roll and pitch, which is transmitted to the launch platform, affecting the stability of the rocket before and after erection. After erection, the rocket is less stable when parked on the launch platform. The large overturning moment caused by the ship's swaying can easily lead to structural failure or even overturning of the rocket. Excessive inclination of the rocket not only affects launch control accuracy but can also cause it to tip over, resulting in launch failure or even an accident. Maintaining a stable and safe free-standing attitude for the rocket before ignition is crucial.

[0003] Existing patent publication number CN117950302A provides a support and control system for a rocket offshore hot launch platform. This system effectively protects the platform, improving the capability of offshore hot launch missions and offering high reliability. However, this system only supports and controls the platform, but does not support or stabilize the rocket, nor prevent it from tipping over.

[0004] Before the rocket is ignited and launched, the sea-launched rocket stabilization device needs to be tilted over to separate the sea-launched rocket stabilization device from the rocket body, so that the rocket can be launched smoothly. However, during the tilting process of the sea-launched rocket stabilization device, impact vibration or rebound will occur, which can easily cause impact damage to the components around the sea-launched rocket stabilization device.

[0035] As a specific embodiment of the present invention, the anti-overturning arm 12 includes a first side support frame and a second side support frame, which are arranged in parallel and connected by a fixed rod. The bottom end of the first side support frame is rotatably connected to the first vertical support frame 21; the bottom end of the second side support frame is rotatably connected to the second vertical support frame 22. The first shock-absorbing and anti-rebound assembly 5 is correspondingly disposed below the first vertical support frame 21, and the second shock-absorbing and anti-rebound assembly 6 is correspondingly disposed below the second vertical support frame 22.

[0036] As a specific embodiment of the present invention, the first side support frame includes multiple horizontal bars and multiple vertical bars. The horizontal bars are arranged parallel to the horizontal bars, the vertical bars are arranged parallel to the vertical bars, and the horizontal bars and the vertical bars are vertically connected to form a frame body of the first side support frame.

[0037] As a specific embodiment of the present invention, the second side support frame includes multiple horizontal bars and multiple vertical bars. The horizontal bars are arranged parallel to the horizontal bars, and the vertical bars are arranged parallel to the vertical bars. The horizontal bars and the vertical bars are vertically connected to form the frame body of the first side support frame.

[0038] like Figure 2-4 As shown, the horizontal bar at the bottom end of the first side support frame is the first side horizontal bar 121; the vertical bar at the end of the first side support frame away from the connection with the first vertical support frame 21 is the first side vertical bar 123. The first side horizontal bar 121 and the first side vertical bar 123 are fixedly connected. The first side horizontal bar 121 and the first side vertical bar 123 are vertically connected, and the first side horizontal bar 121 is rotatably connected to the first vertical support frame 21. The first shock-absorbing and anti-rebound assembly 5 is disposed below the first side horizontal bar 121.

[0039] like Figure 2 As shown, the horizontal bar at the bottom end of the second side support frame is a second side horizontal bar 122; the vertical bar at the end of the second side support frame away from the connection with the second vertical support frame 22 is a second side vertical bar 124. Second side horizontal bar 122 and second side vertical bar 124 are vertically connected, and second side horizontal bar 122 is rotatably connected to the second vertical support frame 22. The second shock-absorbing and anti-rebound assembly 6 is disposed below the second side horizontal bar 122.

[0040] As a preferred embodiment of the present invention, the first shock-absorbing and anti-rebound component 5 and the second shock-absorbing and anti-rebound component 6 are symmetrically arranged, and the first shock-absorbing and anti-rebound component 5 and the second shock-absorbing and anti-rebound component 6 correspond to the first vertical support frame 21 and the second vertical support frame 22 respectively, and are arranged on the sides of the first vertical support frame 21 and the second vertical support frame 22, and the first shock-absorbing and anti-rebound component 5 and the second shock-absorbing and anti-rebound component 6 are respectively correspondingly arranged directly below the two side frames at the bottom of the anti-overturning arm 12. When the anti-overturning arm 12 overturns, the first shock-absorbing and anti-rebound component 5 and the second shock-absorbing and anti-rebound component 6 are supported directly below the two side frames at the bottom of the anti-overturning arm 12, and the first shock-absorbing and anti-rebound component 5 and the second shock-absorbing and anti-rebound component 6 are used to better cushion the anti-overturning arm 12. Assuming that one set of shock-absorbing and anti-rebound components fails, the other set of shock-absorbing and anti-rebound components can still cushion the anti-overturning arm 12.

[0041] like Figure 2 As shown, a long groove 13 is provided on the anti-overturning device chassis 11; the first shock-absorbing and anti-rebound component 5 and the second shock-absorbing and anti-rebound component 6 are connected in the long groove 13. Preferably, two groups of long grooves 13 are provided on the anti-overturning device chassis 11, and the first shock-absorbing and anti-rebound component 5 and the second shock-absorbing and anti-rebound component 6 are respectively connected in the two groups of long grooves 13.

[0042] As a specific embodiment of the present invention, the first shock-absorbing and anti-rebound component 5 and the second shock-absorbing and anti-rebound component 6 have the same structure.

[0043] like Figure 2-4As shown, the first shock-absorbing and anti-rebound assembly 5 and the second shock-absorbing and anti-rebound assembly 6 each include a position-limiting anti-rebound bar 50, a position-limiting block 51, a hinge support 52, an obliquely supported elastic pressure bar 53, and a horizontal elastic pressure bar 54. The position-limiting anti-rebound bar 50 is tilted and arranged below the anti-overturning arm 12. The position-limiting anti-rebound bar 50 is provided with a position-limiting block 51 at its bottom end. The position-limiting anti-rebound bar 50 and the position-limiting anti-rebound bar 51 are integrally connected. The position-limiting block 51 is rotatably connected to the anti-overturning device chassis 11 and is located within the elongated groove 13. The position-limiting block 51 protrudes from the surface of the position-limiting anti-rebound bar 50 on the side facing the anti-overturning arm 12. One end of the oblique support elastic pressure rod 53 is connected to the limiting anti-rebound baffle 50 through a hinge support 52, and the other end is rotatably connected or hinged to the horizontal elastic pressure rod 54. The horizontal elastic pressure rod 54 is arranged on the anti-overturning device chassis 11 in the horizontal direction and is located in the long groove 13. The oblique support elastic pressure rod 53 is tilted and supported and connected to the side of the limiting anti-rebound baffle 50 away from the anti-overturning arm 12, and the tilt direction of the oblique support elastic pressure rod 53 is toward the anti-overturning arm 12. A triangular space is formed between the oblique support elastic pressure rod 53, the limiting anti-rebound baffle 50 and the anti-overturning device chassis 11, thereby improving the stability and support reliability of the connection between the first shock-absorbing anti-rebound component 5 and the second shock-absorbing anti-rebound component 6. The oblique support elastic pressure rod 53 is retractable and the horizontal elastic pressure rod 54 is retractable in the horizontal direction. Both the oblique support elastic pressure rod 53 and the horizontal elastic pressure rod 54 can play a certain shock-absorbing effect. When the anti-overturning arm 12 falls over, the bottom surface of the anti-overturning arm 12 contacts the inclined surface of the position-limiting anti-rebound bar 50, and the position-limiting anti-rebound bar 50 is compressed, causing the position-limiting anti-rebound bar 50 and the position-limiting anti-rebound bar 51 to rotate about the hinge support 52, and the oblique support elastic pressure rod 53 and the horizontal elastic pressure rod 54 are compressed, thereby providing a shock-absorbing effect on the anti-overturning arm 12. When the anti-overturning arm 12 falls into place, the side surface of the anti-overturning arm 12 is parallel to and contacts the inclined surface of the position-limiting anti-rebound bar 50, and the bottom surface of the anti-overturning arm 12 is limited on the position-limiting anti-rebound bar 51. The position-limiting anti-rebound bar 50 limits the anti-overturning arm 12, thereby preventing it from rebounding.

[0044] like Figure 3As shown, a limiting groove is formed at the connection between the limiting block 51 and the limiting anti-rebound blocking rod 50 near the side of the anti-overturning arm 12. Preferably, the limiting groove is a right-angle limiting groove, which forms a 90-degree angle limiting space. Here, the angle formed between the limiting grooves is not limited. The 90-degree angle limiting space formed by the limiting grooves is only a preferred embodiment; the bottom of the side support frame of the anti-overturning arm 12 is a right-angle portion away from the end connected to the vertical support frame 20; when the anti-overturning arm 12 is tilted into place, the anti-overturning arm 12 One end of the bottom of the side support frame of the overturning arm 12 is limited and connected in the limiting groove, that is, the bottom of the side support frame of the anti-overturning arm 12 is limited and connected in the right-angle limiting groove away from the right-angle part connected to one end of the vertical support frame 20. The side surface of the anti-overturning arm 12 is parallel to and in contact with the inclined surface of the limiting anti-rebound block 50. The bottom surface of the anti-overturning arm 12 is limited on the limiting block 51. The limiting anti-rebound block 50 limits the anti-overturning arm 12, thereby preventing the anti-rebound arm 12 from rebounding.

[0045] like Figure 3 As shown, when the anti-overturning arm 12 is tilted into place, the connection between the first side cross bar 121 and the first side vertical bar 123 forms a right angle. The first side cross bar 121 contacts the surface of the limit block 51 near the anti-overturning arm 12 or the surface forming the right-angle limit groove, and the first side vertical bar 123 contacts the surface of the limit anti-rebound stop bar 50 near the anti-overturning arm 12 or the surface forming the right-angle limit groove. The anti-overturning arm 12 is restrained in the right-angle limit groove, thereby preventing the anti-overturning arm 12 from rebounding.

[0046] As a specific embodiment of the present invention, when the anti-overturning arm 12 is tilted into place, the connection between the second side cross bar 122 and the second side vertical bar 124 forms a right angle. The second side cross bar 122 contacts the surface of the limit block 51 close to the anti-overturning arm 12 or the surface forming the right-angle limit groove, and the second vertical bar contacts the surface of the limit anti-rebound stop bar 50 close to the anti-overturning arm 12 or the surface forming the right-angle limit groove. The anti-overturning arm 12 is restrained in the right-angle limit groove, thereby preventing the anti-overturning arm 12 from rebounding.

[0047] like Figure 3 and 4 As shown, the limit stopper 51 is connected to the anti-overturning device chassis 11 through a rotating shaft 55, and the limit stopper 51 can rotate around the rotating shaft 55. The rotating shaft 55 is connected to the elongated groove 13.

[0048] As a specific embodiment of the present invention, when the anti-rebound stopper 50 is subjected to pressure from the anti-overturning arm 12, the diagonal elastic pressure rod 53 and the horizontal elastic pressure rod 54 are compressed. Both the diagonal elastic pressure rod 53 and the horizontal elastic pressure rod 54 are retractable rods. They can be existing hydraulic rods or gas spring support rods.

[0049] The first shock-absorbing and anti-rebound component 5 and the second shock-absorbing and anti-rebound component 6 of the present application realize the automatic locking and anti-rebound effect of the anti-overturning arm 12, avoiding the impact of the rebound of the anti-overturning arm 12 on the launch of the rocket 3. No external force or manual operation is required to achieve the shock-absorbing and anti-rebound effect on the anti-overturning arm 12, which is convenient and quick.

[0050] As a specific embodiment of the present invention, after the anti-overturning arm 12 falls, the anti-overturning arm 12 opens to a certain angle, and the anti-overturning arm 12 contacts the first shock-absorbing anti-rebound component 5 and the second shock-absorbing anti-rebound component 6. The anti-overturning arm 12 continues to fall under its own weight, and the first shock-absorbing anti-rebound component 5 and the second shock-absorbing anti-rebound component 6 are compressed. During this process, the anti-overturning arm 12 slides downward on the contact surface with the first shock-absorbing anti-rebound component 5 and the second shock-absorbing anti-rebound component 6, the oblique support elastic pressure rod 53 and the horizontal elastic pressure rod 54 are compressed, and the anti-overturning arm 12 is decelerated. The first shock-absorbing anti-rebound component 5 and the second shock-absorbing anti-rebound component 6 are compressed to the extreme position, and the anti-overturning arm 12 is limited by the first shock-absorbing anti-rebound component 5 and the second shock-absorbing anti-rebound component 6 and cannot continue to rotate. The oblique support elastic pressure rod 53 and the horizontal elastic pressure rod 54 are not fully compressed, and the anti-overturning arm 12 continues to open and move under the action of inertia. The oblique support elastic pressure rod 53 and the horizontal elastic pressure rod 54 continue to be compressed until the lower end face of the anti-overturning arm 12 contacts the limiting surface of the limit block 51, and the side end face of the anti-overturning arm 12 contacts the limiting surface of the oblique support elastic pressure rod 53, and the anti-overturning arm 12 stops moving.

[0051] The beneficial effects achieved by this application are as follows:

[0052] (1) The present application provides a shock-absorbing and anti-rebound mechanism including a first shock-absorbing and anti-rebound component and a second shock-absorbing and anti-rebound component. The first shock-absorbing and anti-rebound component and the second shock-absorbing and anti-rebound component can both play a role in shock absorption and rebound prevention during the tipping process of the rocket stabilizing device, thereby improving the safety and reliability of the tipping of the rocket stabilizing device.

[0053] (2) The first shock-absorbing and anti-rebound component and the second shock-absorbing and anti-rebound component of the present application realize the automatic locking and anti-rebound effect of the anti-overturning arm, thereby avoiding the impact of the rebound of the anti-overturning arm on the rocket launch.
