Description

Technical Field

[0001] The present invention relates to the technical field of rocket thermal launch equipment, and in particular to an erection device and an erection method for thermal launch of a marine rocket. Background Art

[0002] In the field of rocket launches, the launch platform is usually designed to consist of a fixed frame and an erection frame, and the two are hinged through a rotating axis so that the quiver assembly (a combination of a rocket and a launch tube) can be hoisted and fixed on the erection frame, and the erection frame can be rotated around the rotating axis through the erection system to complete the erection of the rocket. Compared with land launches, sea launches are increasingly valued due to their advantages of low launch costs and small launch energy losses.

[0003] Among them, when launching a rocket at sea, it is often launched on a launching ship. The common erection method is to tilt the cylinder and then lift the erection device through the cylinder. However, since the launching ship is located on the sea, the waves on the sea will cause the launching ship to shake. The shaking of the hull may make it difficult for the tilted erection cylinder to maintain a constant force, thereby affecting the stability of the rocket during the erection process. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a marine rocket hot launch erection device, comprising an erection mechanism, the erection mechanism also comprises a deck, the top of the deck is fixedly connected to a support frame, the top of the support frame is rotatably connected to the erection frame; The counterweight mechanism includes two fixing frames 2 fixedly connected to the side walls of the support frame, the outer walls of the two fixing frames 2 are both slidably connected with counterweight blocks, and the side walls of the support frame are provided with two movable grooves; The supporting mechanism comprises two fixed frames fixedly connected to the top of the deck, the inner walls of the two fixed frames are slidably connected with sliding blocks, and the side walls of the two sliding blocks are fixedly connected with return springs.

[0005] Preferably, the erecting mechanism also includes a rocket placed on the top of the erecting frame, the top of the deck is fixedly connected to an erecting cylinder, the output end of the erecting cylinder at the side wall is fixedly connected to a fixed block, the top of the deck is fixedly connected to a launching platform, the deck is installed on a launching ship, and when the rocket needs to be erected, the erecting cylinder is started to extend, pushing the fixed block to move.

[0006] Preferably, the erecting mechanism also includes a sliding frame fixedly connected to the side wall of the fixed block, a pushing plate is provided at the bottom of the erecting frame, the side wall of the pushing plate is slidably connected to the inner wall of the sliding frame, and two sliding grooves are provided on the side wall of the support frame.

[0007] 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 Fig. 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.

[0008] 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.

[0009] Preferably, the supporting mechanism also includes a connecting rod two rotatably connected to the top of the sliding block, and the top of the supporting frame is fixedly connected to two limit rods, and the top of the supporting frame contacts with a lifting plate, the inner wall of the lifting plate is slidably connected to the outer wall of the limit rod, and the bottom of the lifting plate is slidably connected to the inner wall of the second connecting rod. By utilizing the force of the movement of the counterweight block, when the counterweight block moves toward the direction of the erecting cylinder, it will push the sliding block to move. When the sliding block moves, it will squeeze the reset spring, allowing the reset spring to accumulate rebound force. At the same time, it will also drive the second connecting rod to move, allowing the second connecting rod to fold, pushing the lifting plate to rise and slide at the outer wall of the limit rod. When the lifting plate rises, it will support one side of the erecting cylinder close to the erecting cylinder when the erecting frame is just erected, which can effectively prevent instability caused by changes in the center of gravity when the erecting frame is just erected. This can ensure that the rocket is always in the correct position during the erection process.

[0010] Preferably, the supporting mechanism also includes two fixed sleeves fixedly connected to the top of the deck, spring return rods are slidably connected to the inner walls of the two fixed sleeves, two push rods are fixedly connected to the bottom of the lifting plate, and blocking blocks are rotatably connected to the inner walls of the two fixed sleeves. The tops of the two blocking blocks are fixedly connected to arc springs, and the side walls of the two arc springs are fixedly connected to the side walls of the fixed sleeves. By utilizing the rising force of the lifting plate, when the lifting plate rises, since the spring return rod is in a compressed state, when the lifting plate rises, the rebound force of the spring return rod will be released, causing the spring return rod to rise. At the same time, when the lifting 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, 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.

[0011] A method for erecting a marine rocket hot launch erection device comprises the following steps: S1: 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 push plate to move, and when the push plate moves, it will push the connecting rod to move; S2: The connecting rod rotates and folds, pushing the fixed frame up, thereby driving the erection frame to rotate on the top of the support frame, so that the erection frame is erected, and at the same time, when the plate is pushed to move, it will also slide on the inner wall of the sliding groove; S3: Since the sliding groove is in a segmented rising shape, when the push plate moves a certain distance, it will rise due to the restriction of the shape of the sliding groove, allowing the push plate to slide on the inner wall of the sliding frame.

[0012] The present invention has the following beneficial effects: (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 Fig. 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.

[0013] (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.

[0014] (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.

[0015] (4) The present invention utilizes the force of the lifting plate rising. When the lifting plate rises, since the spring return rod is in a compressed state, when the lifting plate rises, the rebound force of the spring return rod will be released, causing the spring return rod to rise. At the same time, when the lifting 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, 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 and block the spring return rod. As the push rod continues to rise, the bottom of the push rod will push the blocking block to tilt toward the spring return rod until the push rod is separated from the blocking block. At this time, the rebound force 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 lifting plate. Under the influence of the rebound force, the spring return rod will reciprocate and knock on the lifting plate, which can enhance its upward thrust and ensure that the rocket obtains stable support during the erection process.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] For example, see Figure 1 - Figure 3 The present invention is a marine rocket hot launch erection device, comprising an erection mechanism 1, the erection mechanism 1 also comprises a deck 101, the top of the deck 101 is fixedly connected to a support frame 102, the top of the support frame 102 is rotatably connected to an erection frame 103; The counterweight mechanism 2 includes two fixing frames 201 fixedly connected to the side walls of the support frame 102, the outer walls of the two fixing frames 201 are slidably connected with counterweight blocks 202, and the side walls of the support frame 102 are provided with two movable grooves 203; The support mechanism 3 includes two fixed frames 301 fixedly connected to the top of the deck 101, the inner walls of the two fixed frames 301 are slidably connected with sliding blocks 302, and the side walls of the two sliding blocks 302 are fixedly connected with return springs 303.

[0021] The erecting mechanism 1 also includes a rocket 104 placed on the top of the erecting frame 103. The top of the deck 101 is fixedly connected to an erecting cylinder 105, and the output end of the erecting cylinder 105 is fixedly connected to a fixing block 106 at the side wall. The top of the deck 101 is fixedly connected to a launching platform 107. The deck 101 is installed on a launching ship. When the rocket 104 needs to be erected, the erecting cylinder 105 is started to extend and push the fixing block 106 to move.

[0022] The erecting mechanism 1 also 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 erecting 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 provided on the side wall of the supporting frame 102.

[0023] The erecting mechanism 1 also includes two fixed frames 112 fixedly connected to the bottom of the erecting frame 103, the outer wall of the pushing plate 108 is slidably connected to the inner wall of the sliding groove 110, the outer wall of the pushing plate 108 is rotatably connected to two connecting rods 111, the inner walls of the two connecting rods 111 are rotatably connected to the outer wall of the fixed frame 112, driving the sliding frame 109 to move, the sliding frame 109 will push the pushing plate 108 to move, and when the pushing plate 108 moves, it will push the connecting rod 111 to move, so that the connecting rod 111 rotates and folds, pushing the fixed frame 112 to rise, thereby driving the erecting frame 103 to rise, and rotating at 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 a segmented elevated shape, such as Fig. 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 sideways again, causing the folding angle between the connecting rod 111 and the fixed frame 112 to change, and continue to push the erection frame 103 to rise, and so on and so forth, so that the rocket 104 is slowly erected until the rocket 104 is erected on the launching platform 107, and the inclined erection cylinder 105 is changed into a horizontal erection cylinder 105, so as to reduce the influence of the hull shaking on the erection cylinder 105 and make the thrust applied by the erection cylinder 105 more stable.

[0024] For example 2, please refer to Figure 4 - Fig. 9The present invention is a hot launch erection device for a sea rocket. On the basis of the first embodiment, the counterweight mechanism 2 also includes a rotating connecting rod 204 rotatably connected to the side wall of the counterweight block 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 connecting rod 204. Two fixed frames 3 206 are fixedly connected to the side wall of the fixed block 106. The outer walls of the two fixed frames 3 206 are rotatably connected to the inner wall of the rotating connecting rod 204. The force of the movement of the fixed block 106 is used to drive the fixed frame 3 206 to move when the fixed block 106 moves. The fixed frame 3 206 is fixedly connected to the side wall of the fixed block 106. When 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 toward the erecting cylinder 105, so that the counterweight block 202 slides on the surface of the fixed frame 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.

[0025] The support mechanism 3 also includes a second connecting rod 304 rotatably connected to the top of the sliding block 302. The top of the support frame 102 is fixedly connected to two limit rods 306. The top of the support frame 102 contacts a lifting plate 305. The inner wall of the lifting plate 305 is slidably connected to the outer wall of the limit rod 306. The bottom of the lifting plate 305 is slidably connected to the inner wall of the second connecting rod 304. The force of the movement of the counterweight block 202 is used to push the sliding block 302 to move when the counterweight block 202 moves toward the erection cylinder 105. The sliding block 30 2 moves, which will squeeze the reset spring 303, allowing the reset spring 303 to accumulate resilience, and at the same time drive the second connecting rod 304 to move, allowing the second connecting rod 304 to fold, pushing the lifting plate 305 to rise, and slide on the outer wall of the limit rod 306. When the lifting plate 305 rises, it will support the erection frame 103 when it is just erected, close to one side of the erection cylinder 105, which can effectively prevent the erection frame 103 from being unstable due to the change of the center of gravity when it is just erected, so as to ensure that the rocket is always in the correct position during the erection process.

[0026] The supporting mechanism 3 also includes two fixed sleeves 307 fixedly connected to the top of the deck 101, the inner walls of the two fixed sleeves 307 are slidably connected with spring return rods 308, the bottom of the lifting plate 305 is fixedly connected with two push rods 309, the inner walls of the two fixed sleeves 307 are rotatably connected with blocking blocks 310, the tops of the two blocking blocks 310 are fixedly connected with arc springs 311, the side walls of the two arc springs 311 are fixedly connected to the side walls of the fixed sleeves 307, and the lifting plate 305 is lifted by the force of the lifting plate 305. 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, 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.

[0027] There is no limitation on the number of the above components, and relevant technicians in the field can freely set them according to actual needs, as long as the above components are installed at the connection positions of the corresponding components.

[0028] See also Fig.10 The erection method of the marine rocket hot launch erection device comprises the following steps: S1: 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 push plate 108 to move. When the push plate 108 moves, it will push the connecting rod 111 to move; S2: The connecting rod 111 is rotated and folded, pushing the fixing frame 112 to rise, thereby driving the erecting frame 103 to rotate on the top of the supporting frame 102, so that the erecting frame 103 is erected, and at the same time, when the pushing plate 108 moves, it will also slide on the inner wall of the sliding groove 110; S3: Since the sliding groove 110 is in a step-by-step ascending shape, after the push plate 108 moves a certain distance, it will rise due to the restriction of the shape of the sliding groove 110 , allowing the push plate 108 to slide on the inner wall of the sliding frame 109 .

[0029] 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 Fig. 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; 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. Secondly, when the counterweight block 202 moves toward the erecting cylinder 105, it will push the sliding block 302 to move. The movement of the sliding block 302 will squeeze the reset spring 303, allowing the reset spring 303 to accumulate resilience, and at the same time, it will drive the second connecting rod 304 to move, allowing the second connecting rod 304 to fold, pushing the lifting plate 305 to rise and slide on the outer wall of the limit rod 306. When the lifting plate 305 rises, it will support the erection frame 103 when it is just erected, close to the side of the erection cylinder 105, which can effectively prevent the erection frame 103 from being unstable due to the change of the center of gravity when it is just erected, so as to ensure that the rocket is always in the correct position during the erection process; Secondly, 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, 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 the spring return rod 308 will be tilted. The bottom of the push rod 309 will push the blocking block 310 to tilt toward the spring return rod 308 until the push rod 309 is separated from the blocking block 310. At this time, the rebound force 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 lifting plate 305. Under the influence of the rebound force, the spring return rod 308 will reciprocate and knock on the lifting plate 305, which can enhance its upward thrust and ensure that the rocket obtains stable support during the erection process.
