A vertical erection device and method for hot launch of a sea-based rocket

Abstract

The present invention relates to the technical field of rocket hot launch, and discloses an offshore rocket hot launch erection device and an erection method. The erection mechanism includes a deck. A support frame is fixedly connected to the top of the deck, and an erection frame is rotatably connected to the top of the support frame. When the rocket needs to be erected, the erection oil cylinder is started to extend, pushing the fixed block to move, pushing the push plate to move. When the push plate moves, it will push the first connecting rod to move, causing the first connecting rod to rotate and fold, pushing the first fixed frame to rise, thereby driving the erection frame to rotate on the top of the support frame, making the erection frame erect. At the same time, when the push plate moves, it will also slide on the inner wall of the sliding groove, making the rocket slowly erect until the rocket stands on the launch pad, changing the inclined erection oil cylinder into a horizontal erection oil cylinder, reducing the influence of the hull shaking on the erection oil cylinder, and making the thrust applied by the erection oil cylinder more stable.

Description

Technical Field

[0001] The present invention relates to the technical field of rocket hot launch equipment, and specifically relates to an offshore rocket hot launch erection device and an erection method. Background Technique

[0002] In the field of rocket launch, the launch pad is usually designed to consist of a fixed frame and an erection frame, and the two are hinged through a rotating shaft so that the rocket barrel assembly (the assembly of the rocket and the launch barrel) can be hoisted and fixed on the erection frame, and the erection frame is rotated around the rotating shaft through an erection system to complete the erection action of the rocket. Compared with land launch, offshore launch has attracted more and more attention due to its advantages of low launch cost and small launch energy loss.

[0003] Among them, when launching a rocket offshore, it is often launched on a launch ship. In common erection methods, the oil cylinder is often tilted, and then the erection device is jacked up by the oil cylinder. However, since the launch ship is located offshore, the waves on the sea will cause the launch ship to shake, and the shaking of the hull may make it difficult for the tilted erection oil cylinder to maintain a constant force application, thereby affecting the stability during the erection process of the rocket. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides an offshore rocket hot launch erection device, including an erection mechanism. The erection mechanism further includes a deck, a support frame is fixedly connected to the top of the deck, and an erection frame is rotatably connected to the top of the support frame;

[0005] A counterweight mechanism, the counterweight mechanism includes two second fixed frames fixedly connected to the side wall of the support frame, counterweight blocks are slidably connected to the outer walls of the two second fixed frames, and two moving grooves are opened on the side wall of the support frame;

[0006] A support mechanism, the support mechanism includes two fixed frames fixedly connected to the top of the deck, sliding blocks are slidably connected to the inner walls of the two fixed frames, and return springs are fixedly connected to the side walls of the two sliding blocks.

[0007] Preferably, the erection mechanism further includes a rocket placed on the top of the erection frame, an erection oil cylinder is fixedly connected to the top of the deck, a fixed block is fixedly connected to the output end of the side wall of the erection oil cylinder, and a launch pad is fixedly connected to the top of the deck. The deck is installed on the launch ship. When the rocket needs to be erected, the erection oil cylinder is started to extend to push the fixed block to move.

[0008] Preferably, the erection mechanism further includes a sliding frame fixedly connected to the side wall of the fixed block, a pushing plate is arranged at the bottom of the erection frame, the side wall of the pushing plate is slidably connected to the inner wall of the sliding frame, and two sliding grooves are opened on the side wall of the support frame.

[0009] Preferably, the erecting mechanism also includes two fixed frames 1 fixedly connected to the bottom of the erecting frame, the outer wall of the pushing plate is slidably connected to the inner wall of the sliding groove, the outer wall of the pushing plate is rotatably connected to two connecting rods 1, the inner walls of the two connecting rods 1 are rotatably connected to the outer wall of the fixed frame 1, driving the sliding frame to move, the sliding frame will push the pushing plate to move, and when the pushing plate moves, it will push the connecting rod 1 to move, so that the connecting rod 1 rotates and folds, pushing the fixed frame 1 to rise, thereby driving the erecting frame to rotate on the top of the supporting frame, so that the erecting frame is erected, and at the same time, when the pushing plate moves, it will also slide on the inner wall of the sliding groove. Since the sliding groove is a segmented elevated shape, such as Figure 9 As shown, after the push plate moves a certain distance, it is restricted by the shape of the sliding groove and will rise, allowing the push plate to slide on the inner wall of the sliding frame. During the rising process, the push plate will continue to move toward the fixed frame. Therefore, during the rising process of the push plate, the folding angle between the connecting rod 1 and the fixed frame 1 will not change. Since the push plate rises, the connecting rod 1 will also push the erection frame to continue to rise. After the push plate rises a certain distance, it will move horizontally again, causing the folding angle between the connecting rod 1 and the fixed frame 1 to change, continuing to push the erection frame to rise, and so on and so forth, so that the rocket is slowly erected until the rocket is erected on the launch pad, and the inclined erection cylinder is changed into a horizontal erection cylinder, so as to reduce the influence of the hull shaking on the erection cylinder and make the thrust applied by the erection cylinder more stable.

[0010] Preferably, the counterweight mechanism also includes a rotating connecting rod rotatably connected to the side wall of the counterweight block, and two fixed rods are fixedly connected to the bottom of the support frame, and the outer walls of the two fixed rods are slidably connected to the inner wall of the rotating connecting rod, and two fixed frames three are fixedly connected to the side wall of the fixed block, and the outer walls of the two fixed frames three are rotatably connected to the inner wall of the rotating connecting rod. The force of the movement of the fixed block is used to drive the fixed frame three to move when the fixed block moves, and when the fixed frame three moves, it drives the rotating connecting rod to move, so that the rotating connecting rod rotates on the outer wall of the fixed rod. When the rotating connecting rod rotates, it pushes the counterweight block to move toward the direction of the erecting cylinder, so that the counterweight block slides on the surface of the fixed frame two. As the fixed block continues to move, the rotating connecting rod will slide on the outer wall of the fixed rod, pushing the counterweight block away from the support frame. Through the movement of the counterweight block, the center of the rocket is prevented from changing during the erection process of the rocket, and the dynamic movement of the counterweight block can effectively adjust the center of gravity position.

[0011] Preferably, the support mechanism further includes a second connecting rod rotatably connected to the top of the sliding block. Two limiting rods are fixedly connected to the top of the support frame. A jacking plate is in contact with the top of the support frame. The inner wall of the jacking plate is slidably connected to the outer wall of the limiting rod, and the bottom of the jacking plate is slidably connected to the inner wall of the second connecting rod. Using the force generated by the movement of the counterweight, when the counterweight moves towards the erection oil cylinder, it will push the sliding block to move. When the sliding block moves, it will compress the return spring, causing the return spring to accumulate elastic force. At the same time, it will also drive the second connecting rod to move, causing the second connecting rod to fold and push the jacking plate to rise. When the jacking plate rises and slides on the outer wall of the limiting rod, it will support the side close to the erection oil cylinder when the erection frame is just erected, which can effectively prevent the instability caused by the change of the center of gravity when the erection frame is just erected, thus ensuring that the rocket is always in the correct position during the erection process.

[0012] Preferably, the support mechanism further includes two fixed sleeves fixedly connected to the top of the deck. A spring return rod is slidably connected to the inner walls of the two fixed sleeves. Two push rods are fixedly connected to the bottom of the jacking plate. Two blocking blocks are rotatably connected to the inner walls of the two fixed sleeves. Arc-shaped springs are fixedly connected to the tops of the two blocking blocks. The side walls of the two arc-shaped springs are fixedly connected to the side walls of the fixed sleeves. Using the force generated by the rise of the jacking plate, when the jacking plate rises, since the spring return rod is in a compressed state, when the jacking plate rises, the elastic force of the spring return rod will be released, causing the spring return rod to rise. At the same time, when the jacking plate rises, it will also drive the push rods to rise. When the spring return rod rises, it will push the blocking block to rotate, causing the blocking block to tilt. At this time, the side of the blocking block away from the spring return rod will contact the bottom of the push rod, causing the blocking block to stop rotating.

[0013] An erection method for an offshore rocket hot launch erection device includes the following steps:

[0014] S1: Install the deck on the launch ship. When the rocket needs to be erected, start the erection oil cylinder to extend, push the fixed block to move, drive the sliding frame to move, and the sliding frame will push the push plate to move. When the push plate moves, it will push the first connecting rod to move;

[0015] S2: Rotate the first connecting rod to fold it, push the first fixed frame to rise, thereby driving the erection frame to rotate on the top of the support frame and making the erection frame erect. At the same time, when the push plate moves, it will also slide on the inner wall of the sliding groove;

[0016] S3: Since the sliding groove is of a segmented rising shape, when the push plate moves a certain distance, restricted by the shape of the sliding groove, the push plate will rise and slide on the inner wall of the sliding frame.

[0017] The present invention has the following beneficial effects:

[0018] (1) When the present invention is used, the deck is installed on the launch ship. When the rocket needs to be erected, the erection cylinder is started to extend, pushing the fixed block to move, driving the sliding frame to move, and the sliding frame will push the pushing plate to move. When the pushing plate moves, it will push the connecting rod to move, so that the connecting rod rotates and folds, pushing the fixed frame to rise, thereby driving the erection frame to rotate on the top of the support frame, so that the erection frame is erected. At the same time, when the pushing plate moves, it will also slide on the inner wall of the sliding groove. Since the sliding groove is a segmented elevated shape, such as Figure 9 As shown, after the push plate moves a certain distance, it is restricted by the shape of the sliding groove and will rise, allowing the push plate to slide on the inner wall of the sliding frame. During the rising process, the push plate will continue to move toward the fixed frame. Therefore, during the rising process of the push plate, the folding angle between the connecting rod 1 and the fixed frame 1 will not change. Since the push plate rises, the connecting rod 1 will also push the erection frame to continue to rise. After the push plate rises a certain distance, it will move horizontally again, causing the folding angle between the connecting rod 1 and the fixed frame 1 to change, continuing to push the erection frame to rise, and so on and so forth, so that the rocket is slowly erected until the rocket is erected on the launch pad, and the inclined erection cylinder is changed into a horizontal erection cylinder, so as to reduce the influence of the hull shaking on the erection cylinder and make the thrust applied by the erection cylinder more stable.

[0019] (2) The present invention utilizes the force of the movement of the fixed block. When the fixed block moves, it will drive the fixed frame three to move. When the fixed frame three moves, it will drive the rotating connecting rod to move, so that the rotating connecting rod rotates on the outer wall of the fixed rod. When the rotating connecting rod rotates, it will push the counterweight block to move toward the erection cylinder, so that the counterweight block slides on the surface of the fixed frame two. As the fixed block continues to move, the rotating connecting rod will slide on the outer wall of the fixed rod, pushing the counterweight block away from the support frame. Through the movement of the counterweight block, the center of the rocket is prevented from changing during the erection process of the rocket. The dynamic movement of the counterweight block can effectively adjust the center of gravity position, ensuring that the center of gravity is always kept within a reasonable range, thereby avoiding the instability of the launch ship and making the rocket erection process more stable.

[0020] (3) The present invention utilizes the force of the movement of the counterweight block. When the counterweight block moves toward the erecting cylinder, it will push the sliding block to move. The movement of the sliding block will squeeze the reset spring, allowing the reset spring to accumulate resilience. At the same time, it will also drive the second connecting rod to move, causing the second connecting rod to fold, pushing the lifting plate to rise and slide on the outer wall of the limit rod. When the lifting plate rises, it will support the side of the erecting cylinder when the erecting frame is just erected. This can effectively prevent instability caused by changes in the center of gravity when the erecting frame is just erected, thereby ensuring that the rocket is always in the correct position during the erection process.

[0021] (4) The present invention utilizes the upward force of the jacking plate. When the jacking plate rises, since the spring return rod is in a compressed state, when the jacking plate rises, the resilience of the spring return rod will be released, causing the spring return rod to rise. At the same time, when the jacking plate rises, it will also drive the push rod to rise. When the spring return rod rises, it will push the blocking block to rotate, making the blocking block tilt. At this time, the side of the blocking block away from the spring return rod will contact the bottom of the push rod, causing the blocking block to stop rotating and blocking the spring return rod. As the push rod continues to rise, the bottom of the push rod will push the blocking block to tilt towards the spring return rod until the push rod separates from the blocking block. At this time, the resilience of the spring return rod will be released, pushing the blocking block to rotate. At the same time, the top of the spring return rod will contact the bottom of the jacking plate. Affected by the resilience, the spring return rod will reciprocally knock on the jacking plate, which can enhance its upward thrust and ensure stable support for the rocket during the erection process.

Specific embodiments

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Embodiment 1, please refer to Figure 1 - Figure 3 , the present invention is a sea-based rocket hot launch erection device, including an erection mechanism 1. The erection mechanism 1 further includes a deck 101, the top of the deck 101 is fixedly connected with a support frame 102, and the top of the support frame 102 is rotatably connected with an erection frame 103;

[0037] A counterweight mechanism 2, the counterweight mechanism 2 includes two fixing frames two 201 fixedly connected to the side wall of the support frame 102, the outer walls of the two fixing frames two 201 are both slidably connected with counterweight blocks 202, and two moving grooves 203 are opened on the side wall of the support frame 102;

[0038] A support mechanism 3, the support mechanism 3 includes two fixing frames 301 fixedly connected to the top of the deck 101, the inner walls of the two fixing frames 301 are both slidably connected with sliding blocks 302, and return springs 303 are fixedly connected to the side walls of the two sliding blocks 302.

[0039] The erection mechanism 1 further includes a rocket 104 placed on the top of the erection frame 103. A fixed connection is provided at the top of the deck 101 with an erection oil cylinder 105. A fixed block 106 is fixedly connected to the output end at the side wall of the erection oil cylinder 105. A launch pad 107 is fixedly connected to the top of the deck 101. The deck 101 is installed on the launch ship. When the rocket 104 needs to be erected, the erection oil cylinder 105 is started to extend, pushing the fixed block 106 to move.

[0040] The erection mechanism 1 further includes a sliding frame 109 fixedly connected to the side wall of the fixed block 106. A pushing plate 108 is provided at the bottom of the erection frame 103. The side wall of the pushing plate 108 is slidably connected to the inner wall of the sliding frame 109. Two sliding grooves 110 are formed in the side wall of the support frame 102.

[0041] The erection mechanism 1 further includes two first fixed frames 112 fixedly connected to the bottom of the erection frame 103. The outer wall of the pushing plate 108 is slidably connected to the inner wall of the sliding groove 110. Two first connecting rods 111 are rotatably connected to the outer wall of the pushing plate 108. The inner walls of the two first connecting rods 111 are rotatably connected to the outer walls of the first fixed frames 112, driving the sliding frame 109 to move. The sliding frame 109 will push the pushing plate 108 to move. When the pushing plate 108 moves, it will push the first connecting rod 111 to move, causing the first connecting rod 111 to rotate and fold, pushing the first fixed frame 112 to rise, thereby driving the erection frame 103 to rise and rotate on the top of the support frame 102. At the same time, when the pushing plate 108 moves, it will also slide on the inner wall of the sliding groove 110. Since the sliding groove 110 is in a segmented rising shape, as Figure 9 shown, when the pushing plate 108 moves a certain distance, restricted by the shape of the sliding groove 110, the pushing plate 108 will rise, allowing the pushing plate 108 to slide on the inner wall of the sliding frame 109. During the rising process, the pushing plate 108 will continue to move towards the first fixed frame 112. Therefore, during the rising process of the pushing plate 108, the folding angle between the first connecting rod 111 and the first fixed frame 112 will not change. Since the pushing plate 108 has risen, the first connecting rod 111 will also push the erection frame 103 to continue rising. When the pushing plate 108 rises a certain distance, it will move horizontally again, causing the folding angle between the first connecting rod 111 and the first fixed frame 112 to change, and continue to push the erection frame 103 to rise. This process is repeated, slowly erecting the rocket 104 until the rocket 104 stands upright on the launch pad 107, changing the inclined erection oil cylinder 105 into a horizontal erection oil cylinder 105, reducing the influence of the hull shaking on the erection oil cylinder 105, and making the thrust applied by the erection oil cylinder 105 more stable.

[0042] Example two, please refer to Figure 4 - Figure 9, the present invention is a vertical erection device for a sea-based rocket hot launch. On the basis of Embodiment 1, the counterweight mechanism 2 further includes a rotating link 204 rotatably connected to the side wall of the counterweight 202. Two fixed rods 205 are fixedly connected to the bottom of the support frame 102. The outer walls of the two fixed rods 205 are slidably connected to the inner wall of the rotating link 204. Two fixing frames three 206 are fixedly connected to the side wall of the fixed block 106. The outer walls of the two fixing frames three 206 are rotatably connected to the inner wall of the rotating link 204. By using the force of the movement of the fixed block 106, when the fixed block 106 moves, it will drive the fixing frame three 206 to move. When the fixing frame three 206 moves, it will drive the rotating link 204 to move, causing the rotating link 204 to rotate on the outer wall of the fixed rod 205. When the rotating link 204 rotates, it will push the counterweight 202 towards the vertical erection oil cylinder 105, causing the counterweight 202 to slide on the surface of the fixing frame two 201. As the fixed block 106 continues to move, the rotating link 204 will slide on the outer wall of the fixed rod 205, pushing the counterweight 202 away from the support frame 102. By the movement of the counterweight 202, during the erection process of the rocket 104, the center of the rocket 104 will not change. The dynamic movement of the counterweight 202 can effectively adjust the center of gravity position.

[0043] The support mechanism 3 further includes a link two 304 rotatably connected to the top of the sliding block 302. Two limit rods 306 are fixedly connected to the top of the support frame 102. A jacking plate 305 is in contact with the top of the support frame 102. The inner wall of the jacking plate 305 is slidably connected to the outer wall of the limit rod 306. The bottom of the jacking plate 305 is slidably connected to the inner wall of the link two 304. By using the force of the movement of the counterweight 202, when the counterweight 202 moves towards the vertical erection oil cylinder 105, it will push the sliding block 302 to move. When the sliding block 302 moves, it will compress the return spring 303, allowing the return spring 303 to accumulate resilience. At the same time, it will also drive the link two 304 to move, causing the link two 304 to fold and push the jacking plate 305 to rise. The jacking plate 305 slides on the outer wall of the limit rod 306. When the jacking plate 305 rises, it will support on the side close to the vertical erection oil cylinder 105 when the vertical erection frame 103 just starts to be erected, which can effectively prevent the instability caused by the change of the center of gravity when the vertical erection frame 103 just starts to be erected, so as to ensure that the rocket is always in the correct position during the erection process.

[0044] The support mechanism 3 further includes two fixed sleeves 307 fixedly connected to the top of the deck 101. A spring return rod 308 is slidably connected to the inner walls of the two fixed sleeves 307. Two push rods 309 are fixedly connected to the bottom of the lifting plate 305. Blocking blocks 310 are rotatably connected to the inner walls of the two fixed sleeves 307. Arc springs 311 are fixedly connected to the tops of the two blocking blocks 310. The side walls of the two arc springs 311 are fixedly connected to the side walls of the fixed sleeves 307. Using the force of the lifting plate 305 rising, when the lifting plate 305 rises, since the spring return rod 308 is in a compressed state, when the lifting plate 305 rises, the resilience of the spring return rod 308 will be released, causing the spring return rod 308 to rise. At the same time, when the lifting plate 305 rises, it will also drive the push rod 309 to rise. When the spring return rod 308 rises, it will push the blocking block 310 to rotate, making the blocking block 310 tilt. At this time, the side of the blocking block 310 away from the spring return rod 308 will contact the bottom of the push rod 309, causing the blocking block 310 to stop rotating.

[0045] The quantity of the above components is not limited, and those skilled in the relevant art can freely set it according to actual needs, as long as the above components are installed at the corresponding connection positions of the components.

[0046] Please refer to Figure 10 , the erection method of the sea rocket hot launch erection device includes the following steps:

[0047] S1: Install the deck 101 on the launch ship. When the rocket 104 needs to be erected, start the erection oil cylinder 105 to extend, push the fixed block 106 to move, drive the sliding frame 109 to move, and the sliding frame 109 will push the push plate 108 to move. When the push plate 108 moves, it will push the link one 111 to move;

[0048] S2: Make the link one 111 rotate and fold, push the fixed frame one 112 to rise, thereby driving the erection frame 103 to rotate on the top of the support frame 102, making the erection frame 103 erect. At the same time, when the push plate 108 moves, it will also slide on the inner wall of the sliding groove 110;

[0049] S3: Since the sliding groove 110 is of a segmented rising shape, when the push plate 108 moves a certain distance, restricted by the shape of the sliding groove 110, the push plate 108 will rise, allowing the push plate 108 to slide on the inner wall of the sliding frame 109.

[0050] A specific application of this embodiment is: when the present invention is used, the deck 101 is installed on the launch ship. When the rocket 104 needs to be erected, the erection cylinder 105 is started to extend, pushing the fixed block 106 to move, driving the sliding frame 109 to move, and the sliding frame 109 will push the pushing plate 108 to move. When the pushing plate 108 moves, it will push the connecting rod 111 to move, so that the connecting rod 111 rotates and folds, and pushes the fixed frame 112 to rise, thereby driving the erection frame 103 to rotate on the top of the support frame 102, so that the erection frame 103 is erected. At the same time, when the pushing plate 108 moves, it will also slide on the inner wall of the sliding groove 110. Since the sliding groove 110 is a segmented elevated shape, such as Figure 9 As shown, after the push plate 108 moves a certain distance, it is restricted by the shape of the sliding groove 110, and the push plate 108 will rise, allowing the push plate 108 to slide on the inner wall of the sliding frame 109. During the rising process, the push plate 108 will continue to move toward the fixed frame 112. Therefore, during the rising process of the push plate 108, the folding angle between the connecting rod 111 and the fixed frame 112 will not change. Since the push plate 108 rises, the connecting rod 111 will also push the The erection frame 103 continues to rise, and when the push plate 108 rises a certain distance, it will move horizontally again, so that the folding angle between the connecting rod 111 and the fixing frame 112 changes, and the erection frame 103 continues to be pushed up, and this reciprocating process makes the rocket 104 slowly erected until the rocket 104 stands upright on the launch platform 107, and the inclined erection cylinder 105 is changed to a horizontal erection cylinder 105, so that the erection cylinder 105 is less affected by the shaking of the hull, and the thrust applied by the erection cylinder 105 is more stable;

[0051] Secondly, when the fixed block 106 moves, it will drive the fixed frame three 206 to move. When the fixed frame three 206 moves, it will drive the rotating connecting rod 204 to move, so that the rotating connecting rod 204 rotates on the outer wall of the fixed rod 205. When the rotating connecting rod 204 rotates, it will push the counterweight block 202 to move in the direction of the erection cylinder 105, so that the counterweight block 202 slides on the surface of the fixed frame two 201. As the fixed block 106 continues to move, the rotating connecting rod 204 will slide on the outer wall of the fixed rod 205, pushing the counterweight block 202 away from the support frame 102. Through the movement of the counterweight block 202, the center of the rocket 104 is prevented from changing during the erection process of the rocket 104. The dynamic movement of the counterweight block 202 can effectively adjust the center of gravity position, ensuring that the center of gravity is always kept within a reasonable range, thereby avoiding the instability of the launch ship, thereby making the erection process of the rocket 104 more stable.

[0052] Secondly, when the counterweight 202 moves towards the erection oil cylinder 105, it will push the sliding block 302 to move. When the sliding block 302 moves, it will squeeze the return spring 303, causing the return spring 303 to accumulate resilience. At the same time, it will also drive the second connecting rod 304 to move, causing the second connecting rod 304 to fold, pushing the jacking plate 305 to rise and slide on the outer wall of the limit rod 306. When the jacking plate 305 rises, it will support on the side close to the erection oil cylinder 105 when the erection frame 103 just starts to rise, which can effectively prevent the instability caused by the change of the center of gravity when the erection frame 103 just starts to rise, so as to ensure that the rocket is always in the correct position during the erection process;

[0053] Secondly, when the jacking plate 305 rises, since the spring return rod 308 is in a compressed state, when the jacking plate 305 rises, the resilience of the spring return rod 308 will be released, causing the spring return rod 308 to rise. At the same time, when the jacking plate 305 rises, it will also drive the push rod 309 to rise. When the spring return rod 308 rises, it will push the blocking block 310 to rotate, causing the blocking block 310 to tilt. At this time, the side of the blocking block 310 away from the spring return rod 308 will contact the bottom of the push rod 309, causing the blocking block 310 to stop rotating and blocking the spring return rod 308. As the push rod 309 continues to rise, the bottom of the push rod 309 will push the blocking block 310 to tilt towards the spring return rod 308 until the push rod 309 separates from the blocking block 310. At this time, the resilience of the spring return rod 308 will be released, pushing the blocking block 310 to rotate. At the same time, the top of the spring return rod 308 will contact the bottom of the jacking plate 305. Affected by the resilience, the spring return rod 308 will repeatedly knock on the jacking plate 305, which can enhance its upward thrust and ensure stable support for the rocket during the erection process.
