[0043] When conducting meter-scale tests on liquid test rockets, the test rockets may be deflected, overturned, and other uncertain hidden dangers due to various unstable factors such as control, engine, aerodynamics, structure, and external disturbances, which will cause significant property losses, threaten the personal safety of test personnel, and greatly affect the development progress of the aircraft. At present, there are few special devices to protect test rockets from overturning, so when conducting meter-scale tests on test rockets, if an abnormal situation occurs, the test rockets are prone to overturning and causing damage to the rocket body.

[0044] Based on the above technical problems, this embodiment provides a rocket test mooring protection device to protect the test rocket 3, wherein the test rocket 3 includes a rocket body and a bracket arranged at the bottom of the rocket body. Figures 1 to 6 As shown, the rocket test mooring protection device includes a connecting plate assembly 1 and a lifting rope 2, the connecting plate assembly 1 includes a main component 11 and a lifting ring 12, the main component 11 is used to connect the top of the test rocket 3, the top of the test rocket 3 refers to the end of the rocket body away from the bracket, the lifting ring 12 is rotatably connected to the main component 11, one end of the lifting rope 2 is connected to the lifting drive device, and the other end is connected to the lifting ring 12, and the lifting drive device can apply tension to the lifting rope 2. Among them, the lifting drive device can be but not limited to a crane. By connecting the main component 11 to the top of the test rocket 3, after the lifting rope 2 is connected to the lifting ring 12, when the lifting drive device applies tension to the lifting rope 2, it has a traction and pulling effect on the test rocket 3, which can effectively prevent the test rocket 3 from overturning, collapsing and being damaged, and ensure the integrity of the test rocket 3, thereby ensuring the development progress of the aircraft and the personal safety of the test personnel, and reducing the test cost; at the same time, since the lifting ring 12 is rotatably connected to the main component 11, no matter which direction the test rocket 3 falls, the lifting rope 2 can hold the test rocket 3, and can avoid damage to the lifting ring 12 and the main component 11, thereby ensuring the protection effect of the test rocket 3.

[0045] Preferably, the main body component 11 and the hanging ring 12 are made of metal material, which has high structural strength, can withstand large tensile force, and is not easy to deform.

[0046] Specifically, Figure 1 and Figure 2As shown, the main component 11 includes a first connection plate 111, a second connection plate 112 and a plurality of connection rods 113, the first connection plate 111 is annular, the first connection plate 111 is connected to the top of the test rocket 3, the second connection plate 112 is a circular structure, the lifting ring 12 is rotatably connected to the second connection plate 112, and a plurality of connection rods 113 are arranged in annular intervals between the first connection plate 111 and the second connection plate 112, and the two ends of each connection rod 113 are respectively connected to the first connection plate 111 and the second connection plate 112. The annular first connection plate 111 can be more compatible with the top of the test rocket 3, which is convenient for improving the connection stability and ensuring the protection effect of the test rocket 3. Preferably, the shape and size of the first connection plate 111 are compatible with the shape and size of the top of the test rocket 3, so as to improve the force uniformity of the test rocket 3, for example, the first connection plate 111 is circular. The second connecting plate 112 of the circular structure makes the main component 11 evenly stressed, so that the tension applied by the sling 2 to the test rocket 3 through the main component 11 is relatively uniform, which is convenient for protecting the test rocket 3 in all directions, that is, the practicality and reliability of the rocket test mooring protection device are better. The first connecting plate 111 and the second connecting plate 112 are connected by a plurality of connecting rods 113, so that the structural strength of the main component 11 is relatively high, and it is not easy to deform under the action of tension, thereby ensuring the protection effect of the test rocket 3; and the weight of the main component 11 is relatively light, so that the tension can be applied to the test rocket 3 itself as much as possible.

[0047] Preferably, the connecting rod 113 is in the shape of a round tube, which is more evenly stressed, has a higher structural strength, and is not easily deformed by stress.

[0048] More specifically, the main component 11 further includes a reinforcement ring 114 , which is arranged around the outer circumference of the second connecting plate 112 . The reinforcement ring 114 is provided to strengthen the structural strength of the second connecting plate 112 , so that the main component 11 can withstand greater force.

[0049] Furthermore, if Figures 3 to 6 As shown, the connecting plate assembly 1 also includes a lifting ring connecting sleeve 13, and the lifting ring connecting sleeve 13 is connected to the second connecting plate 112. The lifting ring 12 is a rotating lifting ring, and the rotating lifting ring is threadedly connected to the lifting ring connecting sleeve 13. Among them, the rotating lifting ring is a relatively mature prior art, and it is not described one by one here. The rotating lifting ring is threadedly connected to the lifting ring connecting sleeve 13, so that the connection stability between the rotating lifting ring and the lifting ring connecting sleeve 13 is better, and it is easy to disassemble and assemble, and the cost is low.

[0050] In this embodiment, a convex ring 1121 is convexly provided on one side of the second connection plate 112 close to the first connection plate 111, and a mounting groove 11200 is provided on the second connection plate 112, the mounting groove 11200 passes through the convex ring 1121, the lifting ring connecting sleeve 13 is installed in the mounting groove 11200 and the convex ring 1121, and the end of the connecting rod 113 away from the first connection plate 111 is connected to the outer periphery of the convex ring 1121, and the setting of the convex ring 1121 provides an installation space for the lifting ring connecting sleeve 13, so that the installation area is large, thereby ensuring the installation stability. Preferably, each connecting rod 113 is correspondingly provided with at least one reinforcement component, and the reinforcement component includes at least one reinforcement rib plate 115, and the reinforcement rib plate 115 is connected between one end of the connecting rod 113 and the first connection plate 111 or between the connecting rod 113 and the outer periphery of the convex ring 1121, so as to improve the connection strength between the connecting rod 113 and the first connection plate 111 and the second connection plate 112. Exemplarily, two reinforcing ribs 115 are provided at one end of each connecting rod 113 close to the first connecting disk 111, and the two reinforcing ribs 115 are located at opposite sides of the connecting rod 113. One reinforcing rib 115 is provided at one end of each connecting rod 113 close to the second connecting disk 112, and the reinforcing rib 115 is connected between the connecting rod 113 and the outer periphery of the convex ring 1121 to ensure the structural strength and stability of the main component 11. The reinforcing rib 115 can be, but is not limited to, a triangular plate.

[0051] In order to further improve the convenience of disassembly and assembly, the rocket test mooring protection device also includes a shackle (not shown in the figure), and the end of the lifting rope 2 away from the lifting drive device is connected to the shackle, and the shackle is detachably connected to the lifting ring 12. The shackle is more convenient for quick disassembly and assembly of the lifting rope 2, and the main component 11 can be disconnected from the lifting rope 2 without removing the lifting ring 12.

[0052] Specifically, Figure 6As shown, the connecting plate assembly 1 also includes a connecting piece, and the lifting ring connecting sleeve 13 includes a first section 131 and a second section 132. A step surface 133 is formed at the connection between the first section 131 and the second section 132. The cross-sectional area of ​​the first section 131 is smaller than the cross-sectional area of ​​the second section 132. The step surface 133 is provided with a first mounting hole 130 that passes through the second section 132. A second mounting hole 1120 is also provided on the second connecting plate 112. The first section 131 is embedded in the mounting groove 11200, and the step surface 133 abuts against a side of the second connecting plate 112 close to the first connecting plate 111. The connecting piece is connected to the first mounting hole 130 and the second mounting hole 1120. By embedding the first section 131 into the installation groove 11200, the contact area between the lifting ring connecting sleeve 13 and the second connecting plate 112 is larger, which is conducive to enhancing the installation strength. The step surface 133 preferably abuts against the second connecting plate 112, and the step surface 133 and the surface of the second connecting plate 112 have friction, which further enhances the installation strength and maintains the neat and beautiful appearance. At the same time, the second connecting plate 112 and the lifting ring connecting sleeve 13 are connected by a connecting member to ensure the installation stability and reliability of the lifting ring connecting sleeve 13. Exemplarily, the connecting member is a bolt, which passes through the first mounting hole 130 and the second mounting hole 1120 and is threadedly connected to the nut, or the second mounting hole 1120 is a threaded hole, and the bolt passes through the first mounting hole 130 and is threadedly connected to the threaded hole.

[0053] Furthermore, if Figure 1 and Figure 2 As shown, the first connection plate 111 includes a ring-shaped chassis 1111 and a vertical ring 1112 connected to the chassis 1111 at an angle, the chassis 1111 is connected to the top of the test rocket 3, and the end of the connecting rod 113 away from the second connection plate 112 is connected to the vertical ring 1112. The chassis 1111 is convenient for connecting to the top of the test rocket 3, and the vertical ring 1112 is convenient for connecting to the connecting rod 113. The chassis 1111 and the vertical ring 1112 set at an angle have better structural stability. The chassis 1111 and the vertical ring 1112 are preferably connected vertically. Of course, in other embodiments, the chassis 1111 and the vertical ring 1112 can also be set at other angles, such as acute angles or obtuse angles, according to actual needs. Among them, the vertical ring 1112 and the chassis 1111 can be fixed by welding, but not limited to.

[0054] In this embodiment, a plurality of connection holes are provided at intervals along the circumference on the chassis 1111, and bolts are passed through the connection holes to connect with the top of the test rocket 3, which is convenient for disassembly and assembly, and has good structural strength. Of course, in other embodiments, the chassis 1111 can also be connected to the test rocket 3 through other structures, such as welding or clamping, etc., which are specifically set according to actual conditions. Preferably, the connection point between the chassis 1111 and the test rocket 3 is thickened, that is, the thickness within the preset range of the connection hole set on the chassis 1111 is greater than the thickness without the connection hole, so as to ensure the stability and reliability of the connection point, thereby ensuring the reliability and service life of the rocket test mooring protection device. Preferably, a reinforcing rib plate 115 is connected between the connecting rod 113 and the vertical ring 1112 to ensure the connection strength between the connecting rod 113 and the vertical ring 1112. More preferably, reinforcing rib plates 115 are connected between both sides of the connecting rod 113 and the vertical ring 1112 to improve the uniformity of force.

[0055] Preferably, the main body member 11 further includes at least one reinforcing plate 116, which is connected between the chassis 1111 and the vertical ring 1112, and a plurality of reinforcing plates 116 are arranged at intervals along the circumference of the chassis 1111. The reinforcing plates 116 support the vertical ring 1112, preventing the vertical ring 1112 from collapsing toward or away from the chassis 1111 under force. More preferably, a reinforcing plate 116 is arranged on both sides of each connecting hole, and the reinforcing plates 116 are located at the thickened part. At the same time, the two reinforcing plates 116 corresponding to each connecting hole correspond to a connecting rod 113, and the extension line of the connecting rod 113 is located between the two reinforcing plates 116, which not only improves the neatness and aesthetics of the appearance, but also maximizes the structural strength, ensuring that the vertical ring 1112 has a reinforced structural support force at the force-bearing part.

[0056] like Figure 1 As shown, this embodiment also provides a rocket test system, which includes a test rocket 3 and the above-mentioned rocket test mooring protection device, and the main component 11 is connected to the top of the test rocket 3. The test rocket 3 is protected by the rocket test mooring protection device to protect the structural integrity of the test rocket 3 and the personal safety of the test personnel, and to ensure the development progress of the aircraft and reduce the test cost.
