Description

Technical Field

[0001] This invention relates to the field of rocket box capture and recovery technology, and in particular to a Z-shaped layout fixed-length single-rope rocket box capture and recovery net system. Background Technology

[0002] The application prospects of rocket canister capture and recovery technology are broad. First, it can significantly reduce the cost of rocket launches, as the recovered rocket canisters can be reused instead of manufacturing a new one each time. Second, it can improve the launch frequency and reliability of rockets, because the recovered rocket canisters can be reused after simple inspection and maintenance, which can also reduce the generation of space debris and reduce the impact on the environment.

[0003] There are two methods for vertical landing and recovery of rocket housings: retrorockets deceleration and landing with outriggers, and retrorockets deceleration and stable landing with tower outriggers. However, these two methods place strict requirements on the rocket's control capabilities and navigation technology during recovery, and are difficult to implement. Therefore, a Z-shaped layout fixed-length single-rope rocket housing recovery net system is proposed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a Z-shaped layout fixed-length single-rope rocket box capture and recovery net system to solve the problems existing in the prior art and make rocket box interception operations more convenient and faster.

[0005] To achieve the above objectives, the present invention provides the following solution: The present invention provides a Z-shaped layout fixed-length single-rope rocket box capture and recovery net system, comprising:

[0006] A capture and interception mechanism, comprising ropes a, b, c, and d, each of which is provided with two movable pulleys. Rope a between the two movable pulleys is interception segment a, rope b between the two movable pulleys is interception segment b, rope c between the two movable pulleys is interception segment c, and rope d between the two movable pulleys is interception segment d.

[0007] The base has four columns fixedly connected to it, and a guide rail is fixedly connected between two adjacent columns. The moving wheel is slidably connected to the guide rail. Several fixed wheels are provided on the columns, and a traction mechanism is connected to the moving wheel. The traction mechanism is located inside the columns. Ropes a, b, c, and d are all wound around the fixed wheels. The two ends of rope a, b, c, and d are all connected to two diagonally arranged columns. The intercepting segment a is parallel to the intercepting segment b, the intercepting segment c is parallel to the intercepting segment d, and the intercepting segment a is perpendicular to the intercepting segment c.

[0008] Preferably, the four columns include column I, column II, column III, and column IV. The guide rails are fixedly connected between column I and column II, between column II and column III, between column III and column IV, and between column IV and column I. A plurality of fixed wheels are fixedly connected to column I, column II, column III, and column IV.

[0009] Preferably, the two ends of rope a are respectively disposed on column I and column III, the two ends of rope b are respectively disposed on column II and column IV, the two ends of rope c are respectively disposed on column I and column III, and the two ends of rope d are respectively disposed on column II and column IV.

[0010] Preferably, each of the columns I, II, III, and IV is provided with a plurality of traction devices, and the traction devices are connected to the driving wheel via a transmission.

[0011] Preferably, each of the columns I, II, III, and IV is provided with a plurality of rope winding and unwinding mechanisms and a plurality of tensioning mechanisms. Both ends of ropes a, b, c, and d are fixedly connected to the rope winding and unwinding mechanisms, and both ends of ropes a, b, c, and d are provided with the tensioning mechanisms.

[0012] This invention discloses the following technical effects: In this device, interception sections a, b, c, and d are used to capture and intercept rocket housings. The two ends of rope a are set on two diagonally opposite pillars. When viewed from above, rope a is Z-shaped. When the two moving pulleys on rope a move simultaneously in the same direction, rope a only enters interception section a from one side pulley and exits interception section a by the same length from the other side pulley. The length of interception section a remains constant. Similarly, when the two moving pulleys on ropes b, c, and d move simultaneously, the lengths of interception sections b, c, and d also remain constant. During movement, interception sections a and b are parallel, and interception section c and d are parallel, making the interception of rocket housings more reliable. During the movement of all interception sections, the two ends of the rope do not need to move. This invention can effectively reduce the length of ropes a1, b2, c3, and d4, and also reduce the force and work done by the traction mechanism. Attached Figure Description

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Reference Figure 1-5 This invention provides a Z-shaped layout fixed-length single-rope rocket box capture and recovery net system, comprising:

[0023] The capture and interception mechanism includes ropes a1, b2, c3, and d4. Each of ropes a1, b2, c3, and d4 is equipped with two moving pulleys 5. Rope a1 between the two moving pulleys 5 is the interception section a6, rope b2 between the two moving pulleys 5 is the interception section b7, rope c3 between the two moving pulleys 5 is the interception section c8, and rope d4 between the two moving pulleys 5 is the interception section d9.

[0024] The base has four columns fixedly connected to it, and a guide rail 15 is fixedly connected between two adjacent columns. The moving wheel 5 is slidably connected to the guide rail 15. Several fixed wheels 10 are set on the columns. A traction mechanism is connected to the moving wheel 5 and is located inside the column. Ropes a1, b2, c3 and d4 are all wound around the fixed wheels 10. The two ends of rope a1, the two ends of rope b2, the two ends of rope c3 and the two ends of rope d4 are all connected to two diagonally arranged columns. The interception section a6 is parallel to the interception section b7, the interception section c8 is parallel to the interception section d9, and the interception section a6 is perpendicular to the interception section c8.

[0025] Interception sections a6, b7, c8, and d9 are used to intercept the rocket housing. Several moving wheels 5 can slide on guide rail 15. The two ends of rope a1 are set on two diagonally opposite columns. When viewed from above, rope a1 is Z-shaped. The traction mechanism (not shown in the figure) is used to traction the moving wheels 5 to move on guide rail 15. One moving wheel 5 can be connected to two traction mechanisms to facilitate the left and right movement of the moving wheel 5. (See reference) Figure 2 and Figure 1 When the two moving pulleys 5 on rope a1 move simultaneously in the same direction, the length of interception segment a6 remains unchanged. Similarly, when the two moving pulleys on ropes b2, c3, and d4 move simultaneously, the lengths of interception segments b7, c8, and d9 also remain unchanged. This device is mounted on the base, and the fixed pulley 10 on the column changes the direction of ropes a1, b2, c3, and d4, allowing the ends of ropes a1, b2, c3, and d4 to enter the interior of the column. This facilitates the fixing and control of ropes a1, b2, c3, and d4. Interception segment a6 is parallel to interception segment b7, and interception segment c8 is parallel to interception segment d9. Parallel arrangement of the interception rocket housing makes it more reliable.

[0026] The design is further optimized so that the four columns include column I11, column II12, column III13, and column IV14. Guide rails 15 are fixedly connected between column I11 and column II12, between column II12 and column III13, between column III13 and column IV14, and between column IV14 and column I11. Several fixed wheels 10 are fixedly connected to each of the columns I11, column II12, column III13, and column IV14.

[0027] Columns I11, II12, III13, and IV14 are used to support this device. The fixed pulley 10 facilitates the entry of ropes a1, b2, c3, and d4 into the interior of columns I11, II12, III13, and IV14.

[0028] The scheme was further optimized so that the two ends of rope a1 were set on pillar I11 and pillar III13 respectively, the two ends of rope b2 were set on pillar II12 and pillar IV14 respectively, the two ends of rope c3 were set on pillar I11 and pillar III13 respectively, and the two ends of rope d4 were set on pillar II12 and pillar IV14 respectively.

[0029] Rope a1 is mounted on columns I11 and III13 at both ends. Rope a1 is wound around fixed pulley 10 and movable pulley 5. The two movable pulleys 5 on rope a1 are between the two fixed pulleys 10. When viewed from above, rope a1 is zigzag-shaped. Similarly, rope b2 is mounted on columns II12 and IV14 at both ends, rope c3 is mounted on columns I11 and III13 at both ends, and rope d4 is mounted on columns II12 and IV14 at both ends. When viewed from above, ropes b2, c3, and d4 are all zigzag-shaped.

[0030] The design was further optimized by installing several traction devices inside columns I11, II12, III13, and IV14, which are connected to the drive wheel 5 via a transmission.

[0031] Cavities are provided inside columns I11, II12, III13, and IV14. The traction device (not shown in the figure) is located inside the cavity. The traction device (not shown in the figure) is used to pull the moving wheel 5 so that the moving wheel 5 can move easily. When the moving wheel 5 needs to move, the two moving wheels 5 on the same rope move at the same time. For example, the two moving wheels 5 on rope a1 need to move at the same time in the same direction in order to keep the length of the interception section a unchanged. Similarly, the two moving wheels 5 on rope b2 also need to move at the same time, and the moving wheels 5 on rope c3 and rope d4 also need to move at the same time.

[0032] The design was further optimized so that each of the columns I11, II12, III13, and IV14 is equipped with several rope winding and unwinding mechanisms and several tensioning mechanisms. Both ends of ropes a1, b2, c3, and d4 are fixedly connected to the rope winding and unwinding mechanisms, and both ends of ropes a1, b2, c3, and d4 are equipped with tensioning mechanisms.

[0033] The rope retraction and deployment mechanism (not shown in the figure) and the tensioning mechanism (not shown in the figure) are also located in the cavities of columns I 11, II 12, III 13, and IV 14. The rope retraction and deployment mechanism is used to control the lengths of ropes a1, b2, c3, and d4. During the interception of the rocket housing, the rope retraction and deployment mechanism (not shown in the figure) does not need to adjust the lengths of ropes a1, b2, c3, and d4. The tensioning mechanism keeps ropes a1, b2, c3, and d4 taut at all times. Both the rope retraction and deployment mechanism (not shown in the figure) and the tensioning mechanism (not shown in the figure) are adjusted in place before the interception.

[0034] The working principle of this device is as follows: This device is mounted on a base. Interception sections a6, b7, c8, and d9 are used to intercept the rocket casing. Rope a1 is attached to columns I11 and III13 at both ends, and is wound around the fixed pulley 10 and the moving pulley 5. When viewed from above, rope a1 is Z-shaped. Similarly, rope b2 is attached to columns II12 and IV14 at both ends, rope c3 to columns I11 and III13 at both ends, and rope d4 to columns II12 and IV14 at both ends. When viewed from above, ropes b2, c3, and d4 are all Z-shaped. Interception sections a6, b7, c8, and d9 form a grid pattern. The rocket casing falls into the middle of the grid. When the rocket housing is about to contact this device, the moving wheel 5 can be moved by the traction mechanism. During the movement, the two moving wheels 5 on the same rope move simultaneously. At the same time, in order to keep ropes a1 and b2 in place, the moving wheels 5 on ropes a1 and b2 need to move simultaneously. Similarly, the moving wheels 5 on ropes c3 and d4 also need to move simultaneously. When adjusting the positions of interception sections a6, b7, c8, and d9, only the traction mechanism needs to drive the moving wheels 5. The rope winding and tensioning mechanisms do not need to be adjusted. The counterweights at both ends of ropes a1, b2, c3, and d4 are constant. When the traction mechanism drives the moving wheels 5, it does not need to overcome the force of the counterweights, which reduces the work done by the traction mechanism. The lengths of interception sections a6, b7, c8, and d9 remain constant.

[0035] This invention avoids adjustments to the rope retraction and tensioning mechanisms during the capture and interception of rocket housings, significantly reducing the mass of moving parts during rapid capture and decreasing the inertial force during movement, thus reducing the driving power of each rope. Because the rocket housing falls at a very high speed, the response time for the rope system is very short, significantly improving the feasibility of capturing the rocket housing.
