The encircling and clamping mechanism further includes a base. An arc-shaped support frame I is slidably connected to the inner wall of the base. When the outer wall of the rocket contacts the arc-shaped sliding column and moves downward, the hydraulic oil below it is squeezed and flows into the telescopic column I through the communication groove I. The telescopic column I is forced to extend, pushing the U-shaped fixing plate, causing the arc-shaped clamping claws to rotate and form an encirclement of the outer wall of the rocket.

Description

Technical Field

[0001] The present invention relates to the technical field of rocket transportation equipment, and particularly to a rocket transportation device for an offshore platform and its transportation method. Background Art

[0002] The marine environment is complex and changeable, and factors such as wind waves, tides, and ocean currents will all have an adverse impact on the transportation and launch of rockets. When a rocket is transported from a manufacturing factory to an offshore launch platform, it needs to go through two stages: land transportation and sea transportation. During this process, problems such as rocket fixation, shock absorption, and moisture protection need to be solved.

[0003] When transporting a rocket, a rocket fixation device is usually equipped on the rocket transport vehicle to improve the stability of the rocket during transportation and prevent the rocket from shaking during transportation. However, due to the design of the rocket, the outer wall of the rocket is not a smooth cylinder, and there are some protruding and recessed positions on its surface. The existence of these positions will affect the clamping and fixation of the rocket outer wall by the rocket fixation device. In view of the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a rocket transportation device for an offshore platform, including an encircling and clamping mechanism. The encircling and clamping mechanism further includes a base. An arc-shaped support frame I is slidably connected to the inner wall of the base. An arc-shaped clamping claw is rotatably connected to the inner wall of the arc-shaped support frame I. A U-shaped fixing plate is fixedly connected to the outer wall of the arc-shaped clamping claw.

[0005] A support mechanism, the support mechanism includes a fixed bracket fixedly connected to the outer wall of the arc-shaped clamping claw. A telescopic column II is fixedly connected to the outer wall of the fixed bracket. A fixed block II is fixedly connected to the top of the telescopic column II.

[0006] A clamping and fixing mechanism, the clamping and fixing mechanism includes an arc-shaped support frame II slidably connected to the inner wall of the base. A fixed communication plate is fixedly connected to the inner wall of the arc-shaped support frame II. A telescopic spring IV is fixedly connected to the top of the fixed communication plate.

[0007] Preferably, the surrounding clamping mechanism further includes a protruding block slidably connected to the inner wall of the arc-shaped clamping claw. A clamping spring is fixedly connected to the outer wall of the protruding block, and the outer wall of the clamping spring is fixedly connected to the inner wall of the arc-shaped clamping claw. A piston rod is slidably connected to the inner wall of the arc-shaped clamping claw, and an arc-shaped sliding column is slidably connected to the inner wall of the arc-shaped support frame 1. Before transporting the rocket, it is necessary to first place the rocket on this device by hoisting. At this time, the outer wall of the rocket contacts the arc-shaped sliding column and causes it to move downward. When the arc-shaped sliding column moves downward, it squeezes the hydraulic oil below it, causing the hydraulic oil to flow into the interior of the telescopic column 1 through the communication groove 1, causing the telescopic column 1 to extend under the thrust of the hydraulic oil. When the telescopic column 1 extends, it pushes the U-shaped fixing plate, causing the arc-shaped clamping claw to rotate and form a surrounding state around the outer wall of the rocket, thereby achieving preliminary surrounding fixation of the rocket. When the arc-shaped clamping claw rotates, the two arc-shaped clamping claws will contact the piston rod and squeeze and push the piston rod, causing the hydraulic oil below the piston rod to be pressurized and flow into the back of the protruding block, and pushing the protruding block to extend outward, performing secondary clamping fixation on some concave and convex positions on the outer wall of the rocket to increase the contact area and clamping force on the outer wall of the rocket, so that the rocket is more stable during transportation, avoiding the design of some protrusions and depressions on the outer wall of the rocket, resulting in a limited contact area between the arc-shaped clamping claw and the outer wall of the rocket during surrounding fixation, causing the clamping force on the rocket to be relatively reduced and affecting the stability of the rocket during transportation.

[0008] Preferably, the surrounding clamping mechanism further includes a first telescopic spring fixedly connected to the bottom of the arc-shaped sliding column. The bottom of the first telescopic spring is fixedly connected to the inner wall of the arc-shaped support frame 1. A communication groove 1 is provided on the inner wall of the arc-shaped support frame 1. A telescopic column 1 is slidably connected to the inner wall of the arc-shaped support frame 1. The top of the telescopic column 1 is fixedly connected to a first fixing block. The inner wall of the first fixing block is rotatably connected to the outer wall of the U-shaped fixing plate. The top of the arc-shaped sliding column is fixedly connected to the rocket. By pressing down the arc-shaped sliding column, the hydraulic oil below the arc-shaped sliding column is squeezed, causing the hydraulic oil to flow through the communication groove 1 into the interior of the telescopic column 1, causing the telescopic column 1 to extend outward, and then moving the U-shaped fixing plate through the first fixing block. After the arc-shaped sliding column loses contact with the outer wall of the rocket, the arc-shaped sliding column is reset by the first telescopic spring, facilitating the next loading of the rocket.

[0009] Preferably, the support mechanism further includes a hydraulic pipe fixedly connected to the inner wall of the telescopic column 2. A first support plate is rotatably connected to the inner wall of the second fixing block. The inner wall of the first support plate is fixedly connected to the outer wall of the hydraulic pipe. A sliding plate is slidably connected to the inner wall of the first support plate. When the arc-shaped clamping claw rotates, the first support plate contacts the outer wall of the rocket and causes the telescopic column 2 to be squeezed and contract, allowing the hydraulic oil inside the telescopic column 2 to flow into the interior of the first support plate through the hydraulic pipe and pushing the sliding plate to move outward, increasing the contact area between the first support plate and the outer wall of the rocket, facilitating subsequent support of the outer wall of the rocket.

[0010] Preferably, the support mechanism further includes a second support plate slidably connected to the inner wall of the sliding plate. The outer wall of the second support plate is slidably connected to the inner wall of the first support plate. A second telescopic spring is fixedly connected to the outer wall of the second support plate, and the outer wall of the second telescopic spring is fixedly connected to the inner wall of the sliding plate. A third telescopic spring is fixedly connected to the bottom of the first arc-shaped support frame, and the bottom of the third telescopic spring is fixedly connected to the inner wall of the base. By using the feature that the arc-shaped clamping claws perform circumferential clamping on the outer wall of the rocket during rotation, four fixed brackets are provided. When the arc-shaped clamping claws rotate, the telescopic column two and the first support plate are driven by the fixed brackets to approach the outer wall of the rocket together. After the first support plate contacts the outer wall of the rocket, the telescopic column two is compressed and contracted, and the hydraulic oil inside the telescopic column two flows into the first support plate through the hydraulic pipe. After the hydraulic oil enters the inside of the first support plate, it pushes the sliding plate to extend outwards. When the sliding plate extends to the maximum value, the second support plate loses contact with the first support plate, and the hydraulic oil then pushes the second support plate to extend outwards and be flush with the first support plate, increasing the contact area between the first support plate and the outer wall of the rocket. When the arc-shaped clamping claws rotate, the rocket can be supported from both sides by the first support plate and the second support plate, reducing the pressure on the first arc-shaped support frame and the arc-shaped sliding column, and avoiding the situation that due to the large weight of the rocket itself and the small stress points of the first arc-shaped support frame and the arc-shaped sliding column, the rocket remains in a constant state during transportation for a long time, causing some deformation of the outer wall of the rocket and affecting the subsequent flight of the rocket when it is launched into the air.

[0011] Preferably, the support mechanism further includes a hydraulic groove formed in the inner wall of the base. A third telescopic column is slidably connected to the inner wall of the base. A third fixed block is fixedly connected to the top of the third telescopic column. A third support plate is rotatably connected to the inner wall of the third fixed block. By using the characteristic that the above-mentioned arc-shaped sliding column descends under force, when the arc-shaped sliding column descends due to the weight of the rocket, it synchronously drives the first arc-shaped support frame to descend. When the first arc-shaped support frame descends, it squeezes the hydraulic oil below the first arc-shaped support frame, causing the hydraulic oil to flow to both ends through the hydraulic groove. After the hydraulic oil flows to the bottom of the third telescopic column, it moves upward to push the third telescopic column to extend, so that the third support plate contacts the head of the outer wall of the rocket and supports its head. And after the hydraulic oil flows through the hydraulic groove to the bottom of the second arc-shaped support frame, it pushes the second arc-shaped support frame upward to move and contact the tail of the outer wall of the rocket and support its tail. Through the operation mode of the above components, when the first arc-shaped support frame descends, the third support plate and the second arc-shaped support frame rise to support the head and tail of the rocket, which is convenient for adjusting the support height of the front and rear of the rocket, improving the loading efficiency, and adjusting the support height can keep the rocket in a relatively horizontal state with the base, which is convenient for the transportation of the rocket. Avoid tilting during transportation due to the excessive length of the rocket and the different sizes and weights of the front and rear, resulting in the head or tail hitting the base, causing damage to the outer wall of the rocket, affecting the subsequent launch and flight trajectory of the rocket. At the same time, the bottoms of the first arc-shaped support frame, the third support plate, and the second arc-shaped support frame are interconnected through hydraulic oil. During transportation, the movement of the hydraulic oil at the bottom can play a certain role in buffering and shock absorption, reducing the vibration of the rocket during transportation.

[0012] Preferably, the clamping and fixing mechanism further includes a fourth telescopic column slidably connected to the inner wall of the second arc-shaped support frame. A second communication groove is formed in the inner wall of the fourth telescopic column. A fixed partition is fixedly connected to the inner wall of the fourth telescopic column. A telescopic block is slidably connected to the inner wall of the fourth telescopic column. A fifth telescopic spring is fixedly connected to the outer wall of the telescopic block. The outer wall of the second telescopic spring is fixedly connected to the outer wall of the fixed partition. By using the characteristic that the hydraulic oil pushes the second arc-shaped support frame upward to move, when the hydraulic oil pushes the second arc-shaped support frame upward to move, the hydraulic oil will also pass through the inside of the second arc-shaped support frame, and then pass through the fixed communication plate, and then push the fourth telescopic column upward to move. When the fourth telescopic column moves upward to the maximum value, the top of the fourth telescopic column will contact the tail of the outer wall of the rocket. At this time, the telescopic block, which was originally in contact with the fourth telescopic column, loses contact with it after the fourth telescopic column extends. The hydraulic oil can flow to the back of the telescopic block through the communication groove two and push the telescopic block to move outward and extend, so that the telescopic block can be clamped between the rocket thrusters to form a clamping and fixing of the tail of the rocket, improving the stability of the rocket during transportation, avoiding the rocket from shaking during transportation, causing the rocket to tilt, and the outer wall of the rocket to be knocked and damaged, thus affecting the subsequent launch and flight trajectory of the rocket after launch.

[0013] A transportation method for a rocket transportation device on an offshore platform, comprising the following steps:

[0014] S1: Push and extend. When the arc-shaped sliding column moves downward, it squeezes the hydraulic oil below it, causing the hydraulic oil to flow into the interior of the telescopic column 1 through the connecting groove 1, and making the telescopic column 1 extend under the thrust of the hydraulic oil.

[0015] S2: Encircle and fix. When the telescopic column 1 extends, it pushes the U-shaped fixing plate, causing the arc-shaped clamping claws to rotate, forming a state of encircling the outer wall of the rocket, so as to achieve preliminary encircling and fixing of the rocket.

[0016] S3: Squeeze and clamp. When the arc-shaped clamping claws rotate, the arc-shaped clamping claws on both sides will contact the piston rod and squeeze and push the piston rod, causing the hydraulic oil below the piston rod to be pressurized and flow into the back of the protruding block, and pushing the protruding block to extend outward, so as to perform secondary clamping and fixing on some concave and convex positions on the outer wall of the rocket.

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

[0018] (1) Before transporting the rocket, the rocket needs to be placed on this device by hoisting. At this time, the outer wall of the rocket contacts the arc-shaped sliding column and causes it to move downward. When the arc-shaped sliding column moves downward, it squeezes the hydraulic oil below it, causing the hydraulic oil to flow into the interior of the telescopic column 1 through the connecting groove 1, and making the telescopic column 1 extend under the thrust of the hydraulic oil. When the telescopic column 1 extends, it pushes the U-shaped fixing plate, causing the arc-shaped clamping claws to rotate, forming a state of encircling the outer wall of the rocket, so as to achieve preliminary encircling and fixing of the rocket. When the arc-shaped clamping claws rotate, the arc-shaped clamping claws on both sides will contact the piston rod and squeeze and push the piston rod, causing the hydraulic oil below the piston rod to be pressurized and flow into the back of the protruding block, and pushing the protruding block to extend outward, so as to perform secondary clamping and fixing on some concave and convex positions on the outer wall of the rocket, so as to increase the contact area and clamping force on the outer wall of the rocket, thereby making the rocket more stable during transportation, and avoiding the situation that due to some protruding and concave designs on the outer wall of the rocket, the contact area between the arc-shaped clamping claws and the outer wall of the rocket is limited during encircling and fixing, resulting in a relatively reduced clamping force on the rocket and affecting the stability of the rocket during transportation.

[0019] (2) The present invention utilizes the characteristic that the arc-shaped clamping claw can clamp the outer wall of the rocket in a ring when rotating, and sets four fixed brackets. When the arc-shaped clamping claw rotates, the fixed brackets drive the telescopic column 2 and the support plate 1 to approach the outer wall of the rocket. After the support plate 1 contacts the outer wall of the rocket, the telescopic column 2 is compressed and contracted, and the hydraulic oil inside the telescopic column 2 flows into the support plate 1 through the hydraulic pipe. After the hydraulic oil enters the support plate 1, it pushes the sliding plate to extend outward. When the sliding plate extends to the maximum value, the support plate 2 loses contact with the support plate 1, and the hydraulic oil Instead, support plate two is pushed outward to be flush with support plate one, so that the contact area between support plate one and the outer wall of the rocket is increased. When the arc-shaped clamping claw rotates, the rocket can be lifted and supported from both sides by support plates one and two, thereby reducing the pressure on arc-shaped support frame one and arc-shaped sliding column, and avoiding that due to the heavy weight of the rocket itself and the small stress points of arc-shaped support frame one and arc-shaped sliding column, the rocket remains in one state for a long time during transportation, causing some deformation of the outer wall of the rocket, which will have a certain impact on the subsequent launch of the rocket.

[0020] (3) The present invention utilizes the characteristic of the arc-shaped sliding column being subjected to downward force. When the arc-shaped sliding column is subjected to downward force due to the weight of the rocket, the arc-shaped support frame 1 is driven downward synchronously. When the arc-shaped support frame 1 is descended, the hydraulic oil under the arc-shaped support frame 1 is squeezed, so that the hydraulic oil flows to both ends through the hydraulic groove. After the hydraulic oil flows to the bottom of the telescopic column 3, it moves upward to push the telescopic column 3 to extend, so that the support plate 3 contacts the head of the outer wall of the rocket and supports its head. After the hydraulic oil flows to the bottom of the arc-shaped support frame 2 through the hydraulic groove, it pushes the arc-shaped support frame 2 to move upward, contacts the tail of the outer wall of the rocket and supports its tail. Through the operation mode of the above-mentioned components, when the arc-shaped support frame 1 is descended, The support plate three and the arc-shaped support frame two rise to support the head and tail of the rocket, making it convenient to adjust the support height of the front and rear of the rocket, improving the loading efficiency, and adjusting the support height can keep the rocket and the base in a relatively horizontal state, facilitating the transportation of the rocket, and avoiding the rocket being tilted during transportation due to being too long and having different sizes and weights at the front and back, causing the head or tail to collide with the base, causing damage to the outer wall of the rocket, and affecting the subsequent launch and flight trajectory of the rocket. At the same time, the bottoms of the arc-shaped support frame one, the support plate three and the arc-shaped support frame two are interconnected by hydraulic oil. During transportation, the movement of the hydraulic oil at the bottom can play a certain role in buffering and shock absorption, reducing the shaking of the rocket during transportation.

[0021] (4) The present invention utilizes the characteristic that hydraulic oil pushes the arc-shaped support frame 2 to move upward. When the hydraulic oil pushes the arc-shaped support frame 2 to move upward, the hydraulic oil will also pass through the interior of the arc-shaped support frame 2, and then pass through the fixed connecting plate, thereby pushing the telescopic column 4 to move upward. When the telescopic column 4 moves upward to the maximum value, the top of the telescopic column 4 will contact the tail of the outer wall of the rocket. At this time, the telescopic block is originally in contact with the telescopic column 4, but loses contact with it after the telescopic column 4 is extended. The hydraulic oil can flow to the back of the telescopic block through the connecting groove 2 and push the telescopic block to move outward and extend, so that the telescopic block can be stuck between the rocket thrusters and the rocket thrusters, forming a clamping position and fixing the tail of the rocket, thereby improving the stability of the rocket during transportation, avoiding the rocket from shaking during transportation, causing the rocket to tilt, causing the outer wall of the rocket to be bumped and damaged, and affecting the subsequent launch of the rocket and the trajectory of the flight after launch.

[0034] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiment 1. Please refer to Figure 1 - Figure 4 , the present invention is a rocket transportation device for an offshore platform, including an encircling clamping mechanism 1. The encircling clamping mechanism 1 further includes a base 101. An inner wall of the base 101 is slidably connected with a first arc-shaped support frame 102. An inner wall of the first arc-shaped support frame 102 is rotatably connected with an arc-shaped clamping claw 103.

[0037] A positioning and fixing mechanism 3. The positioning and fixing mechanism 3 includes a second arc-shaped support frame 301 slidably connected to an inner wall of the base 101. An inner wall of the second arc-shaped support frame 301 is fixedly connected with a fixed communication plate 302. A top of the fixed communication plate 302 is fixedly connected with a fourth telescopic spring 303.

[0038] The embracing clamping mechanism 1 also includes a protruding block 105 slidably connected to the inner wall of the arc-shaped clamping claw 103, a clamping spring 106 is fixedly connected to the outer wall of the protruding block 105, the outer wall of the clamping spring 106 is fixedly connected to the inner wall of the arc-shaped clamping claw 103, a piston rod 107 is slidably connected to the inner wall of the arc-shaped clamping claw 103, and an arc-shaped sliding column 108 is slidably connected to the inner wall of the arc-shaped support frame 102. Before transporting the rocket, the rocket needs to be placed on the device by hoisting. At this time, the outer wall of the rocket contacts and moves downward with the arc-shaped sliding column 108. When the arc-shaped sliding column 108 moves downward, the hydraulic oil below it is squeezed, so that the hydraulic oil flows into the interior of the telescopic column 111 through the connecting groove 110, so that the telescopic column 111 is extended by the thrust of the hydraulic oil. When the U-shaped fixing plate 104 is pushed, the arc-shaped clamping claws 103 are rotated to form an embracing state with the outer wall of the rocket to achieve preliminary embracing and fixing of the rocket. When the arc-shaped clamping claws 103 rotate, the arc-shaped clamping claws 103 on both sides will contact the piston rod 107 and squeeze and push the piston rod 107, so that the hydraulic oil under the piston rod 107 is pressurized to flow into the back of the protruding block 105 and push the protruding block 105 to extend outward. For some concave and convex positions on the outer wall of the rocket, secondary clamping and fixing are performed to increase the contact area and clamping strength with the outer wall of the rocket, so that the rocket is more stable during transportation, and the design of some protrusions and depressions on the outer wall of the rocket is avoided, so that the arc-shaped clamping claws 103 are limited in contact with the outer wall of the rocket when embracing and fixing, resulting in a relatively reduced clamping force on the rocket, affecting the stability of the rocket during transportation.

[0039] The embracing clamping mechanism 1 also includes a telescopic spring 109 fixedly connected to the bottom of the arc-shaped sliding column 108, the bottom of the telescopic spring 109 is fixedly connected to the inner wall of the arc-shaped support frame 102, the inner wall of the arc-shaped support frame 102 is provided with a connecting groove 110, the inner wall of the arc-shaped support frame 102 is slidably connected with a telescopic column 111, the top of the telescopic column 111 is fixedly connected with a fixed block 112, the inner wall of the fixed block 112 is rotatably connected to the outer wall of the U-shaped fixed plate 104, and the arc The top of the arc-shaped sliding column 108 is fixedly connected to the rocket 113. The arc-shaped sliding column 108 is pressed down to squeeze the hydraulic oil under the arc-shaped sliding column 108, so that the hydraulic oil flows through the connecting groove 110 to the inside of the telescopic column 111, so that the telescopic column 111 extends outward, and then the U-shaped fixed plate 104 is moved through the fixed block 112. After the arc-shaped sliding column 108 loses contact with the outer wall of the rocket, the arc-shaped sliding column 108 is reset by the telescopic spring 109 to facilitate the loading of the rocket next time.

[0040] For example 2, please refer to Figure 5 - Figure 9, the present invention is a rocket transportation device for an offshore platform. On the basis of Embodiment 1, the support mechanism 2 further includes a hydraulic pipe 204 fixedly connected to the inner wall of the telescopic column two 202. A support plate one 205 is rotatably connected to the inner wall of the fixed block two 203. The inner wall of the support plate one 205 is fixedly connected to the outer wall of the hydraulic pipe 204. A sliding plate 206 is slidably connected to the inner wall of the support plate one 205. When the arc-shaped clamping claw 103 rotates, the support plate one 205 contacts the outer wall of the rocket, causing the telescopic column two 202 to be squeezed and thus contract. The hydraulic oil inside the telescopic column two 202 flows through the hydraulic pipe 204 into the inside of the support plate one 205, and pushes the sliding plate 206 to move outward, increasing the contact area between the support plate one 205 and the outer wall of the rocket, facilitating the subsequent support of the outer wall of the rocket.

[0041] The support mechanism 2 further includes a support plate two 207 slidably connected to the inner wall of the sliding plate 206. The outer wall of the support plate two 207 is slidably connected to the inner wall of the support plate one 205. An expansion spring two 208 is fixedly connected to the outer wall of the support plate two 207. The outer wall of the expansion spring two 208 is fixedly connected to the inner wall of the sliding plate 206. An expansion spring three 209 is fixedly connected to the bottom of the arc-shaped support frame one 102. The bottom of the expansion spring three 209 is fixedly connected to the inner wall of the base 101. By utilizing the characteristic that the arc-shaped clamping claw 103 performs circumferential clamping on the outer wall of the rocket during rotation, four fixed brackets 201 are provided. When the arc-shaped clamping claw 103 rotates, the telescopic column two 202 and the support plate one 205 are driven by the fixed brackets 201 to approach the outer wall of the rocket together. After the support plate one 205 contacts the outer wall of the rocket, the telescopic column two 202 is compressed and contracts. The hydraulic oil inside the telescopic column two 202 flows into the support plate one 205 through the hydraulic pipe 204. After the hydraulic oil enters the inside of the support plate one 205, it pushes the sliding plate 206 to extend outward. When the sliding plate 206 extends to the maximum value, the support plate two 207 loses contact with the support plate one 205. The hydraulic oil then pushes the support plate two 207 to extend outward and be flush with the support plate one 205, increasing the contact area between the support plate one 205 and the outer wall of the rocket. When the arc-shaped clamping claw 103 rotates, the rocket can be supported from both sides by the support plate one 205 and the support plate two 207, reducing the pressure on the arc-shaped support frame one 102 and the arc-shaped sliding column 108, and avoiding the situation that due to the large weight of the rocket itself and the small stress points of the arc-shaped support frame one 102 and the arc-shaped sliding column 108, the rocket remains in one state unchanged during transportation for a long time, causing some deformation of the outer wall of the rocket and affecting the subsequent flight of the rocket when it is launched into the air.

[0042] The support mechanism 2 further includes a hydraulic groove 210 formed in the inner wall of the base 101. A third telescopic column 211 is slidably connected to the inner wall of the base 101. A third fixed block 212 is fixedly connected to the top of the third telescopic column 211. A third support plate 213 is rotatably connected to the inner wall of the third fixed block 212. By utilizing the characteristic that the arc-shaped sliding column 108 descends under force, when the arc-shaped sliding column 108 descends due to the weight of the rocket, it synchronously drives the first arc-shaped support frame 102 to descend. When the first arc-shaped support frame 102 descends, it squeezes the hydraulic oil below the first arc-shaped support frame 102, causing the hydraulic oil to flow towards both ends through the hydraulic groove 210. After the hydraulic oil flows under the third telescopic column 211, it moves upward to push the third telescopic column 211 to extend, so that the third support plate 213 contacts the head of the outer wall of the rocket and supports its head. And after the hydraulic oil flows through the hydraulic groove 210 to below the second arc-shaped support frame 301, it pushes the second arc-shaped support frame 301 to move upward, contacts the tail of the outer wall of the rocket, and supports its tail. Through the operation mode of the above components, when the first arc-shaped support frame 102 descends, the third support plate 213 and the second arc-shaped support frame 301 rise to support the head and tail of the rocket, which is convenient for adjusting the support height of the front and rear of the rocket, improving the loading efficiency. And by adjusting the support height, the rocket can be kept in a relatively horizontal state with the base 101, which is convenient for the transportation of the rocket. It can avoid the rocket being too long, with different sizes and weights at the front and rear, tilting during transportation, causing the head or tail to collide with the base 101, resulting in damage to the outer wall of the rocket, affecting the subsequent launch and flight trajectory of the rocket. At the same time, the bottoms of the first arc-shaped support frame 102, the third support plate 213 and the second arc-shaped support frame 301 are interconnected through hydraulic oil. During transportation, the movement of the hydraulic oil at the bottom can play a certain role in buffering and shock absorption, reducing the vibration of the rocket during transportation.

[0043] The clamping and fixing mechanism 3 further includes a telescopic column four 304 slidably connected to the inner wall of the arc-shaped support frame two 301. A communication groove two 305 is formed in the inner wall of the telescopic column four 304. A fixed partition 306 is fixedly connected to the inner wall of the telescopic column four 304. A telescopic block 307 is slidably connected to the inner wall of the telescopic column four 304. A telescopic spring five 308 is fixedly connected to the outer wall of the telescopic block 307. The outer wall of the telescopic spring two 208 is fixedly connected to the outer wall of the fixed partition 306. By utilizing the characteristic that the hydraulic oil pushes the arc-shaped support frame two 301 upward, when the hydraulic oil pushes the arc-shaped support frame two 301 upward, the hydraulic oil will also pass through the inside of the arc-shaped support frame two 301, then pass through the fixed communication plate 302, and further push the telescopic column four 304 upward. When the telescopic column four 304 moves upward to the maximum value, the top of the telescopic column four 304 will contact the tail of the rocket outer wall. At this time, the telescopic block 307, which was originally in contact with the telescopic column four 304, loses contact with it after the telescopic column four 304 extends. The hydraulic oil can flow through the communication groove two 305 to the back of the telescopic block 307 and push the telescopic block 307 to move outward and extend, so that the telescopic block 307 can be clamped between the rocket thrusters to form a clamping and fixing of the rocket tail, thereby improving the stability of the rocket during transportation, avoiding the rocket from shaking during transportation, causing the rocket to tilt, and the outer wall of the rocket to be knocked and damaged, which will affect the subsequent launch of the rocket and the flight trajectory after launch.

[0044] The transportation method of the rocket transportation device for the offshore platform includes the following steps:

[0045] S1: Push and extend. When the arc-shaped sliding column 108 moves downward, it squeezes the hydraulic oil below it, causing the hydraulic oil to flow into the inside of the telescopic column one 111 through the communication groove one 110, and the telescopic column one 111 is pushed out by the thrust of the hydraulic oil.

[0046] S2: Surround and fix. When the telescopic column one 111 extends, it pushes the U-shaped fixing plate 104, causing the arc-shaped clamping claws 103 to rotate and form a surrounding state around the outer wall of the rocket to achieve preliminary surrounding and fixing of the rocket.

[0047] S3: Extrude and clamp. When the arc-shaped clamping claws 103 rotate, the two arc-shaped clamping claws 103 on both sides will contact the piston rod 107 and squeeze and push the piston rod 107, causing the hydraulic oil below the piston rod 107 to be pressurized and flow to the back of the protruding block 105, and push the protruding block 105 to extend outward to perform secondary clamping and fixing on some concave and convex positions of the rocket outer wall.

[0048] A specific application of this embodiment is as follows: Before using the device, first install the device on a rocket transporter. When the rocket is placed on this device by hoisting, the outer wall of the rocket contacts the arc-shaped sliding column and causes it to move downward. When the arc-shaped sliding column moves downward, it squeezes the hydraulic oil below it, causing the hydraulic oil to flow into the interior of the first telescopic column through the first connecting groove, so that the first telescopic column extends under the thrust of the hydraulic oil. When the first telescopic column extends, it pushes the U-shaped fixing plate, causing the arc-shaped clamping claws to rotate and form a surrounding state around the outer wall of the rocket, thereby achieving preliminary surrounding fixation of the rocket. When the arc-shaped clamping claws rotate, the arc-shaped clamping claws on both sides will contact the piston rod and squeeze and push the piston rod, causing the hydraulic oil below the piston rod to be pressurized and flow into the back of the protruding block, and pushing the protruding block to extend outward, for secondary clamping fixation of some concave and convex positions on the outer wall of the rocket, so as to increase the contact area and clamping force on the outer wall of the rocket, making the rocket more stable during transportation, and avoiding the design of some protrusions and depressions on the outer wall of the rocket, which causes the contact area between the arc-shaped clamping claws and the outer wall of the rocket to be limited during surrounding fixation, resulting in a relatively reduced clamping force on the rocket and affecting the stability of the rocket during transportation.

[0049] Utilizing the characteristic that the arc-shaped clamping claws perform circumferential clamping on the outer wall of the rocket during rotation, four fixed brackets are set. When the arc-shaped clamping claws rotate, the fixed brackets drive the second telescopic column and the first support plate to approach the outer wall of the rocket together. After the first support plate contacts the outer wall of the rocket, the second telescopic column is compressed and contracted, and the hydraulic oil inside the second telescopic column flows into the first support plate through the hydraulic pipe. After the hydraulic oil enters the interior of the first support plate, it pushes the sliding plate to extend outward. When the sliding plate extends to the maximum value, the second support plate loses contact with the first support plate, and the hydraulic oil then pushes the second support plate to extend outward and be flush with the first support plate, increasing the contact area between the first support plate and the outer wall of the rocket. When the arc-shaped clamping claws rotate, the first support plate and the second support plate can lift and support the rocket from both sides, reducing the pressure on the first arc-shaped support frame and the arc-shaped sliding column, and avoiding the situation that due to the large weight of the rocket itself and the small force-bearing points of the first arc-shaped support frame and the arc-shaped sliding column, the rocket remains in a state unchanged for a long time during transportation, causing some deformation of the outer wall of the rocket and affecting the subsequent flight of the rocket when it is launched into the air.

[0050] Taking advantage of the characteristic that the above-mentioned arc-shaped sliding column descends under force, when the arc-shaped sliding column descends due to the weight of the rocket, it synchronously drives the first arc-shaped support frame to descend. When the first arc-shaped support frame descends, it squeezes the hydraulic oil under the first arc-shaped support frame, causing the hydraulic oil to flow towards both ends through the hydraulic groove. After the hydraulic oil flows under the third telescopic column, it moves upward to push the third telescopic column to extend, so that the third support plate contacts the head of the rocket outer wall and supports its head. And after the hydraulic oil flows through the hydraulic groove to under the second arc-shaped support frame, it pushes the second arc-shaped support frame to move upward, contacts the tail of the rocket outer wall, and supports its tail. Through the operation mode of the above components, when the first arc-shaped support frame descends, the third support plate and the second arc-shaped support frame rise to support the head and tail of the rocket, facilitating the adjustment of the support height before and after the rocket, improving the loading efficiency, and adjusting the support height can keep the rocket in a relatively horizontal state with the base, facilitating the transportation of the rocket. Avoiding the inclination during transportation due to the excessive length of the rocket and the different sizes and weights before and after, resulting in the head or tail colliding with the base, causing damage to the rocket outer wall, affecting the subsequent launch and flight trajectory of the rocket. At the same time, the bottoms of the first arc-shaped support frame, the third support plate, and the second arc-shaped support frame are interconnected through hydraulic oil. During transportation, the movement of the hydraulic oil at the bottom can play a certain role in buffering and shock absorption, reducing the vibration of the rocket during transportation. When the hydraulic oil pushes the second arc-shaped support frame to move upward, the hydraulic oil will also pass through the inside of the second arc-shaped support frame, then pass through the fixed connecting plate, and further push the fourth telescopic column to move upward. When the fourth telescopic column moves upward to the maximum value, the top of the fourth telescopic column will contact the tail of the rocket outer wall. At this time, the expansion block originally contacted the fourth telescopic column and loses contact with it after the fourth telescopic column extends. The hydraulic oil can flow through the second communication groove to the back of the expansion block and push the expansion block to move outward and extend, so that the expansion block can be stuck between the rocket thrusters to form a clamping fixation for the tail of the rocket, improving the stability of the rocket during transportation, avoiding the rocket from shaking during transportation, causing the rocket to tilt, and the outer wall of the rocket to be knocked and damaged, thus affecting the subsequent launch and the flight trajectory after launch of the rocket.
