Description

Technical Field

[0001] This invention relates to the field of rocket launch technology, and more specifically, to a rocket launch support device. Background Technology

[0002] In my country, rockets are typically launched vertically via hot launch. During horizontal transport, clamping and locking devices restrict the rocket's freedom of movement in the longitudinal, lateral, vertical, and roll directions. Before erection, the launch system and rocket are automatically or manually unlocked. After erection, the tail cone presses against the launch pad support, and a wind-resistant tie rod mechanism is installed, requiring manual contact before launch. While this method meets the requirements for land-based erection and launch operations, in marine environments, waves, swells, and wind loads can cause irregular rocket roll, leading to accidental activation of the launch contact switch and preventing ignition. Furthermore, large rockets experience high impact acceleration during long-distance transport, causing excessive localized loads at the locking device, which is detrimental to the rocket engine's structural design. Therefore, it is necessary to develop new rocket launch support devices to meet the transportation, erection, and launch requirements of missiles and rockets. Summary of the Invention

[0028] The following is a detailed explanation and description of a rocket launch support device according to the present invention, with reference to the accompanying drawings.

[0029] like Figure 1 , Figure 2 and combined Figure 3As shown in the figure, an embodiment of the present invention discloses a rocket launch support device, including a support ring 1 and a launch pad 2 arranged vertically. The support ring 1 includes an upper circular plate 11, a lower circular plate 13, and an annular cylinder 12 arranged coaxially. The upper circular plate 11 is fixed to the upper end of the annular cylinder 12, and the lower circular plate 13 is fixed to the lower end of the annular cylinder 12. A plurality of ribs 14 are provided circumferentially at intervals along the outer periphery of the annular cylinder 12. The upper end face of the ribs 14 is fixedly connected to the lower end face of the upper circular plate 11, and the lower end face of the ribs 14 is fixedly connected to the upper end face of the lower circular plate 13. The annular cylinder 12 is provided with cable through holes 15, and the inner side of the annular cylinder 12 is fitted with... Equipped with a release device 3 and a launch contact bracket 4, the release device 3 is installed near the cable through-hole 15. The launch contact bracket 4 is height-adjustable and abuts against the launch contact at the tail end of the rocket. The upper circular plate 11 is equipped with a fixing component 16 that is detachably connected to the tail end of the rocket and a roll-limiting pin 17 that limits the roll of the rocket. The lower circular plate 13 is connected to the launch pad 2 via several legs 5. The center of the launch pad 2 is provided with a launch pad 2 through hole corresponding to the center hole of the ring cylinder 12.

[0030] In practical applications, the coaxially arranged upper circular plate 11, lower circular plate 13, and ring cylinder 12 of the support ring 1 constitute the core of the support ring 1 structure. The upper circular plate 11 is fixed to the upper end of the ring cylinder 12, and the lower circular plate 13 is fixed to the lower end of the ring cylinder 12. This design allows the support ring 1 to remain stable during launch and effectively transfer loads. Multiple ribs 14 are spaced circumferentially along the outer periphery of the ring cylinder 12. The upper end face of these ribs 14 is fixedly connected to the lower end face of the upper circular plate 11, and the lower end face is fixedly connected to the upper end face of the lower circular plate 13. These ribs 14 increase the strength of the support ring 1. The ring cylinder 12 also has cable perforations 15 to facilitate cable passage through the support ring 1, providing power and communication support for the rocket. A release device 3 and a launch contact bracket 4 are installed on the inner side of the ring cylinder 12. The release device 3 is installed close to the cable perforation 15, facilitating cable connection and disconnection. The takeoff contact bracket 4 can be raised and lowered to abut against the takeoff contact at the rocket's tail end, thus securing it in the appropriate position before launch and providing a precise takeoff signal when the rocket separates from the support ring 1. The upper circular plate 11 is equipped with a fixing component 16 detachably connected to the rocket's tail end and a roll-limiting pin 17 to restrict rocket roll. The fixing component 16 ensures the rocket does not misalign during transport and erection and needs to be removed before launch. The roll-limiting pin 17 prevents the rocket from rolling during vertical preparation and launch, improving launch stability and safety. The lower circular plate 13 is connected to the launch pad 2 via several legs 5. The launch pad 2 has a through hole in its center corresponding to the center hole of the ring cylinder 12. The legs 5 provide sufficient installation space for the support ring 1 when connected to the launch pad 2, providing a solid foundation for rocket launch.

[0031] In this embodiment, during road transport and long-distance ocean transport, this device, together with the support bracket, provides the rocket with constraints on its longitudinal, lateral, vertical, and roll directions, preventing misalignment. It eliminates the need for additional clamping or locking devices, resulting in a simple structure. Before rocket erection, the fixing component 16 is manually removed, placing the rocket in a free state, eliminating the need for complex electromechanical equipment and improving reliability. During the vertical launch phase, the addition of a roll-limiting pin 17 effectively restricts the rocket's roll, preventing accidental triggering of the launch contact switch. This fully utilizes the existing rocket structure, requiring no modifications or additional restraint release equipment. During launch, the roll-limiting pin 17 restricts the rocket's roll, enabling a more stable vertical ascent, avoiding errors caused by roll, and does not impede flight. It eliminates the need for active or passive unlocking, improving launch accuracy.

[0032] like Figure 1 and combined Figure 4 As shown, in one embodiment of the present invention, the upper circular plate 11 is provided with a plurality of first connecting holes, second connecting holes, and first limiting holes along the circumference. A reinforcing ring 18 is fixed by connecting bolts. The connecting bolts pass through the first connecting holes of the upper circular plate 11 from bottom to top and are screwed into the reinforcing ring 18. The reinforcing ring 18 is provided with third connecting holes and second limiting holes that match the second connecting holes and first limiting holes of the upper circular plate 11, respectively. The fixing member 16 passes through the second connecting holes and third connecting holes and is connected to the tail of the rocket. The lower half of the limiting roll pin 17 is screwed into the first limiting hole and the second limiting hole, and the upper half protrudes from the second limiting hole. The upper half is configured as a smooth rod and has a clearance fit with the connecting component of the tail of the rocket. This design can effectively reduce the vibration and shaking of the rocket during flight, ensuring the stability and accuracy of the rocket. At the same time, the setting of the reinforcing ring 18 can increase the structural strength of the rocket, improve the load-bearing capacity of the rocket, and the reinforcing ring 18 bears the erosion of the rocket exhaust flow during launch, avoiding the ablation damage to the support ring 1 body and increasing the number of uses of the support ring 1. The design of the roll-limiting pin 17 restricts the rocket's roll, ensuring the stability of its flight direction. The clearance fit between the smooth rod and the connecting parts at the rocket's tail ensures the rocket's flexibility and stability, thereby improving its accuracy.

[0033] More specifically, such as Figure 8 As shown, Figure 8 In order to be in Figure 2 Based on the foundation, only the fastener 16, connecting bolts, and roll-limiting pins 17 are retained, wherein there are 9 roll-limiting pins 17 (i.e., attached). Figure 8 (As indicated by the dotted line), the positions of these 9 limit roll pins 17 are as follows: Figure 8A roll-limiting pin 17 is set at the top, and four roll-limiting pins 17 are symmetrically arranged on the left and right sides of the center line of this roll-limiting pin. The intervals between these four roll-limiting pins 17 and the top roll-limiting pin 17 from top to bottom with the circumference as the center are 50°, 20°, 30° and 20° respectively. With the above arrangement, the purpose of limiting the rocket roll can be achieved by using the fewest number of roll-limiting pins 17, and the mechanical structure of the support ring 1 can be guaranteed.

[0034] like Figure 2 and combined Figure 3 As shown, in one embodiment of the present invention, the width of the lower circular plate 13 is at least three times the width of the upper circular plate 11. The rib 14 is a right-angled trapezoid, with its upper parallel side being the same width as the upper circular plate 11 and its lower parallel side being the same width as the lower circular plate 13. The upper end of the hypotenuse of the right-angled trapezoid connects to the outer edge of the upper circular plate 11, and the lower end of the hypotenuse connects to the outer edge of the lower circular plate 13. The fact that the width of the lower circular plate 13 is at least three times the width of the upper circular plate 11 allows for better support and distribution of the pressure on the upper circular plate 11. The right-angled trapezoidal shape of the rib 14 provides stable support and better connects the upper circular plate 11 and the lower circular plate 13. The fact that the upper parallel side of the right-angled trapezoid is the same width as the upper circular plate 11 ensures a tight connection between the rib 14 and the upper circular plate 11, preventing uneven stress distribution. The lower parallel side of the right-angled trapezoid is the same width as the lower circular plate 13, ensuring a tight connection between the rib plate 14 and the lower circular plate 13, and providing stable support on the lower circular plate 13. The upper end of the hypotenuse of the right-angled trapezoid connects to the outer ring edge of the upper circular plate 11, ensuring that the rib plate 14 and the upper circular plate 11 form a stable whole and effectively distributing the pressure on the upper circular plate 11. The lower end of the hypotenuse of the right-angled trapezoid connects to the outer ring edge of the lower circular plate 13, ensuring that the rib plate 14 and the lower circular plate 13 form a stable whole and provide stable support on the lower circular plate 13.

[0035] like Figure 1 and combined Figure 5As shown, in one embodiment of the present invention, the components of the release device 3 include a mounting base 31, a guide 32, a limiting steel cable 33, and a pulling steel cable 34. The mounting base 31 is an L-shaped structure perpendicular to the vertical part, with the horizontal part fixed to the lower end face of the lower circular plate 13 and the vertical part located inside the annular cylinder 12. The upper half of the vertical part is provided with a mounting groove 311, and the lower end of the guide 32 is fixed in the mounting groove 311 of the vertical part. The lower end face of the guide 32 is provided with an arc groove 321, one end of the limiting steel cable 33 is fixed to the upper end of the guide 32, and the free end of the limiting steel cable 33 is provided with a first connector 331, and the first connector 331 is provided with a cotter pin 332. The pulling steel cable 34 passes through the arc groove 321 of the guide 32, and the two free ends of the pulling steel cable 34 are respectively provided with a second connector 341 and a third connector 342. The first connector 331, the second connector 341, and the third connector 342 are used to connect to the pull-out cable at the tail of the rocket.

[0036] In this embodiment, the design of the release device 3 is simple and efficient, ensuring its safe, stable, and reliable operation during rocket launch. The one-piece molding design of the mounting base 31 makes the entire device compact and facilitates installation and maintenance. The design of the guide 32 cleverly utilizes the cooperation between the arc groove 321 and the limiting steel cable 33, allowing the pulling steel cable 34 to move accurately along the predetermined path, thus ensuring the smooth progress of the release process. The selection and design of the limiting steel cable 33 and the pulling steel cable 34 also fully consider the actual operating environment and requirements. The strength and stiffness of the limiting steel cable 33 ensure its stability and reliability under impact loads, while the flexibility and strength of the pulling steel cable 34 enable it to effectively transmit tension, ensuring the normal operation of the release device 3. The arrangement of the first connector 331, the second connector 341, and the third connector 342 allows the release device 3 to achieve a quick and stable connection with the release cable at the tail of the rocket. This design not only improves work efficiency but also reduces operating difficulty and maintenance costs. In summary, the design of this detachment device 3 fully considers actual usage needs and the operating environment, and has advantages such as simple structure, convenient operation, and safety and reliability. At the same time, its connection method with the rocket's tail detachment cable makes the entire system more flexible and stable, providing a strong guarantee for the successful launch of the rocket.

[0037] like Figure 1 and combined Figure 6As shown, in one embodiment of the present invention, the takeoff contact bracket 4 includes a support block 41, a connecting rod 42, a circular plate 43, and a housing 44. The support block 41 is fixed to the inner wall of the annular cylinder 12. A threaded hole is provided in the middle of the support block 41. The connecting rod 42 is threaded and screwed into the threaded hole of the support block 41 from bottom to top. The housing 44 has an opening on the upper side and a through hole in the center of the bottom of the housing 44. The circular plate 43 is disposed inside the housing 44. The upper end of the connecting rod 42 passes through the through hole of the housing 44 and is fixedly connected to the lower end face of the circular plate 43. A cover plate 45 is welded onto the housing 44 to close its opening. The takeoff contact bracket 4 is installed on the inner wall of the annular cylinder 12. The housing 44 has an opening on the upper side and a through hole in the center of the bottom of the housing 44 so that the upper end of the connecting rod 42 passes through the through hole of the housing 44 and is fixedly connected to the lower end face of the circular plate 43. When height adjustment is required, the connecting rod 42 is rotated from bottom to top and screwed into the threaded hole of the support block 41 to adjust the height of the bracket. When the cover plate 45 of the housing 44 is about to contact the contacts of the takeoff switch, the housing 44 is manually lifted upwards to abut against the contacts of the takeoff switch. The connecting rod 42 is then rotated, allowing the circular plate 43 to rotate inside the housing 44. Finally, the circular plate 43 presses the cover plate 45 tightly against the inside of the housing 44, thus pressing the takeoff contact bracket 4 against the contacts of the takeoff switch at the tail end of the rocket. During this process, the housing 44 will not rotate, so the cover plate 45 will not have lateral frictional displacement with the contacts of the takeoff switch, providing a certain degree of protection for the contacts of the takeoff switch. After being pressed tightly, a continuous contact signal is fed back before the rocket launch, indicating that the rocket has not yet left the launch pad 2; a disconnection signal is fed back after the rocket launch, indicating that the rocket has left the launch pad 2.

[0038] like Figure 1 and combined Figure 7As shown, in one embodiment of the present invention, the support leg 5 includes a lower support base 51, a telescopic member 52, and an upper support base 53. The lower support base 51 is fixed on the launch platform 2. The telescopic member 52 includes a cylinder and a telescopic rod. The cylinder is fixed on the lower support base 51, and the telescopic rod can extend and retract under the restriction of the cylinder. The upper end of the telescopic rod is a spherical connector 521. The upper end of the upper support base 53 is fixedly connected to the lower circular plate 13. The lower half of the upper support base 53 is provided with a hemispherical groove that matches the spherical connector 521. The lower end of the upper support base 53 is also provided with a split ball head sleeve 54. The inner circumferential wall of the ball head sleeve 54 matches the shape of the spherical connector 521. The spherical connector 521 is located in the groove of the lower half of the upper support base 53 and is fixedly connected to the upper support base 53 through the split ball head sleeve 54. In actual use, the rocket's tail section is first connected to the support ring 1, while the launch pad 2 is connected to the erector frame. Once the rocket is hoisted to the appropriate position, a reliable connection can be achieved through the extension and retraction of the outriggers 5. The core components of the outriggers 5 include the lower support base 51, the telescopic component 52, and the upper support base 53. The lower support base 51 is securely mounted on the launch pad 2, providing basic support for the entire structure. The telescopic component 52 consists of a cylinder and a telescopic rod. The cylinder is fixed to the lower support base 51, and the telescopic rod can extend and retract freely within the constraints of the cylinder, facilitating adaptive adjustment and installation in confined spaces. The upper end of the upper support base 53 is fixedly connected to a circular lower plate, providing stable upper support. The lower half of the upper support 53 is provided with a hemispherical groove that matches the spherical connector 521. The lower end of the upper support 53 also features a split ball head sleeve 54, whose inner circumferential wall perfectly matches the shape of the spherical connector 521, allowing the spherical connector 521 to be securely embedded in the groove. This provides a certain degree of axial offset during rocket installation, facilitating the overall centering and alignment of the rocket. The upper support 53 can be installed using bolts. Specifically, both the upper support 53 and the lower circular plate 13 have matching elongated holes. These holes allow for a certain degree of installation deviation, facilitating the installation of the upper support 53 and the lower circular plate 13. For connection stability, a connecting plate can be placed between two adjacent elongated holes, allowing the bolts to be tightened through the connecting plate.

[0039] In one embodiment of the present invention, in order to fix the connecting cable at the tail end of the rocket, multiple binding rings are welded to the inner peripheral wall of the annular cylinder 12, and the binding rings are close to the cable through hole 15. The binding rings are U-shaped, and the two free ends of the U-shape are welded to the inner peripheral wall of the annular cylinder 12. Multiple binding rings can be provided, arranged horizontally or vertically, so as to facilitate binding the connecting cable according to actual needs. In order to facilitate the hoisting of the support ring 1, hoisting holes are provided on the stiffening plate 14 on the outer peripheral wall of the annular cylinder 12 corresponding to the cable through hole 15, and on the stiffening plate 14 on the other side of the outer peripheral wall of the annular cylinder 12 directly opposite the cable through hole 15. To facilitate the connection between launch pad 2 and the erecting frame, launch pad 2 is designed as a square. Two spaced-apart hinge lugs are provided on the rear side wall of launch pad 2 for hinge connection with the erecting frame. A left pin hole is provided at the front end of the left side wall of launch pad 2, and a right pin hole, opposite to the left pin hole, is provided at the front end of the right side wall of launch pad 2. The launch pad is fixedly connected to the erecting frame through the left and right pin holes. Two spaced-apart support leg mounting seats 31 are provided at the front end of the lower side wall of launch pad 2 for installing launch pad support legs, ensuring sufficient support for launch pad 2 after rocket erection. Furthermore, a heat insulation plate is laid on the upper side wall of launch pad 2 to prevent burns and increase the number of uses of launch pad 2.
