[0043] When a liquid test rocket is performing a meter-level test, the test rocket may deviate, overturn, and other uncertain hidden trouble conditions due to various unstable factors such as control, engine, aerodynamics, structure, external disturbance, etc., thereby causing significant property loss, also threatening the personal safety of test personnel, and greatly affecting the development progress of the spacecraft. At present, there are few special devices for protecting the test rocket from overturning, so that when the test rocket is performing a meter-level test, if an abnormal condition occurs, the test rocket is easy to overturn and cause damage to the rocket body.

[0044] Based on the above technical problems, the present embodiment provides a rocket test tether protection device for protecting a test rocket 3, wherein the test rocket 3 includes a rocket body and a support arranged at the bottom of the rocket body. As shown in Figures 1 to 6 The rocket test tether protection device includes a connecting disc assembly 1 and a hoisting rope 2. The connecting disc assembly 1 includes a main body member 11 and a lifting ring 12. The main body member 11 is used to connect the top end of the test rocket 3, and the top end of the test rocket 3 refers to the end of the rocket body away from the support. The lifting ring 12 is rotationally connected to the main body member 11. One end of the hoisting rope 2 is connected to a hoisting driving device, and the other end is connected to the lifting ring 12. The hoisting driving device can exert a pulling force on the hoisting rope 2. The hoisting driving device can be, but is not limited to, a crane. By connecting the main body member 11 to the top end of the test rocket 3, when the hoisting driving device exerts a pulling force on the hoisting rope 2 after the hoisting rope 2 is connected to the lifting ring 12, the test rocket 3 is pulled and dragged, which can effectively prevent the test rocket 3 from overturning and collapsing and being damaged, ensure the integrity of the test rocket 3, and thus ensure the development progress of the spacecraft and the personal safety of the test personnel, and reduce the test cost. At the same time, since the lifting ring 12 is rotationally connected to the main body member 11, no matter which direction the test rocket 3 tilts, the hoisting rope 2 can pull the test rocket 3, and damage to the lifting ring 12 and the main body member 11 can be avoided, ensuring the protection effect of the test rocket 3.

[0045] Preferably, the main body member 11 and the lifting ring 12 are made of metal material, which has high structural strength and can withstand a large pulling force without being easily deformed.

[0046] Specifically, as shown in Figure 1 and Figure 2As shown, the main body member 11 comprises a first connecting disc 111, a second connecting disc 112 and a plurality of connecting rods 113, the first connecting disc 111 is annular, the first connecting disc 111 is connected with the top end of the test rocket 3, the second connecting disc 112 is circular structure, the lifting ring 12 is rotatably connected on the second connecting disc 112, the plurality of connecting rods 113 are annularly and spacedly arranged between the first connecting disc 111 and the second connecting disc 112, and the two ends of each connecting rod 113 are connected with the first connecting disc 111 and the second connecting disc 112 respectively. The annular first connecting disc 111 can be more suitable for the top end of the test rocket 3, so as to improve the connection stability and ensure the protection effect on the test rocket 3. Preferably, the shape and size of the first connecting disc 111 are adapted to the shape and size of the top end of the test rocket 3, so as to improve the stress uniformity of the test rocket 3, for example, the first connecting disc 111 is circular. The circular structure of the second connecting disc 112 makes the main body member 11 bear stress uniformly, so that the tension applied to the test rocket 3 by the lifting rope 2 through the main body member 11 is more uniform, which is convenient for protecting the test rocket 3 in each direction, that is, the practicability and reliability of the rocket test tether protection device are better. And the first connecting disc 111 and the second connecting disc 112 are connected through the plurality of connecting rods 113, so that the structural strength of the main body member 11 is higher and is not easy to deform under the action of tension, so as to ensure the protection effect on the test rocket 3; and the weight of the main body member 11 is lighter, so that the tension can be applied to the test rocket 3 as much as possible.

[0047] Preferably, the connecting rod 113 is circular tube, which bears stress more uniformly and has higher structural strength and is not easy to deform under stress.

[0048] More specifically, the main body member 11 further comprises a reinforcing ring 114, the reinforcing ring 114 is annularly arranged on the outer periphery of the second connecting disc 112, and the structural strength of the second connecting disc 112 is strengthened by arranging the reinforcing ring 114, so that the main body member 11 can bear larger force.

[0049] Further, as shown, Figures 3 to 6 the connecting disc assembly 1 further comprises a lifting ring connecting sleeve 13, the lifting ring connecting sleeve 13 is connected to the second connecting disc 112, the lifting ring 12 is a rotary lifting ring, and the rotary lifting ring is threadedly connected to the lifting ring connecting sleeve 13. The rotary lifting ring is a relatively mature prior art, which will not be described here. The rotary lifting ring is threadedly connected to the lifting ring connecting sleeve 13, so that the connection stability of the rotary lifting ring and the lifting ring connecting sleeve 13 is better, and the rotary lifting ring is convenient to disassemble and assemble and has lower cost.

[0050] In the embodiment, the second connecting plate 112 is provided with a protruding ring 1121 on the side close to the first connecting plate 111, and the second connecting plate 112 is provided with a mounting groove 11200, the mounting groove 11200 penetrating the protruding ring 1121, the lifting ring connecting sleeve 13 is mounted in the mounting groove 11200 and the protruding ring 1121, and the connecting rod 113 is connected to the outer periphery of the protruding ring 1121 away from the first connecting plate 111. The protruding ring 1121 provides a mounting space for the lifting ring connecting sleeve 13, so that the installation area is larger, thereby ensuring the installation stability. Preferably, at least one reinforcing assembly is arranged on each connecting rod 113, the reinforcing assembly comprises at least one reinforcing rib plate 115, the reinforcing rib plate 115 is connected to one end of the connecting rod 113 and the first connecting plate 111 or between the connecting rod 113 and the outer periphery of the protruding ring 1121, thereby improving the connection strength of the connecting rod 113 and the first connecting plate 111 and the second connecting plate 112. For example, two reinforcing rib plates 115 are arranged on each connecting rod 113 close to the first connecting plate 111, the two reinforcing rib plates 115 are located on opposite sides of the connecting rod 113, one reinforcing rib plate 115 is arranged on each connecting rod 113 close to the second connecting plate 112, the reinforcing rib plate 115 is connected between the connecting rod 113 and the outer periphery of the protruding ring 1121, thereby ensuring the structural strength and stability of the main body member 11. The reinforcing rib plate 115 can be a triangular plate, but is not limited thereto.

[0051] In order to further improve the disassembly and assembly convenience, the rocket test tether protection device further comprises a release buckle (not shown in the figure), the lifting rope 2 is connected to the release buckle away from the lifting driving device, and the release buckle is detachably connected to the lifting ring 12. The release buckle is more convenient for quickly disassembling and assembling the lifting rope 2, and the main body member 11 can be disconnected from the lifting rope 2 without disassembling the lifting ring 12.

[0052] Specifically, as Figure 6As shown, the connecting plate assembly 1 further comprises a connecting piece, the lifting ring connecting sleeve 13 comprises a first section 131 and a second section 132, and 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 that of the second section 132, the step surface 133 is provided with a first mounting hole 130 penetrating through the second section 132, the second connecting plate 112 is further provided with a second mounting hole 1120, the first section 131 is embedded in the mounting groove 11200, the step surface 133 abuts against the side of the second connecting plate 112 close to the first connecting plate 111, and the connecting piece is connected to the first mounting hole 130 and the second mounting hole 1120. By embedding the first section 131 in the mounting groove 11200, the contact area of the lifting ring connecting sleeve 13 and the second connecting plate 112 is larger, which is beneficial to enhancing the installation strength, the step surface 133 is preferably abutted on the second connecting plate 112, the step surface 133 has friction with the surface of the second connecting plate 112, which further enhances the installation strength and keeps the appearance neat and beautiful. At the same time, the second connecting plate 112 and the lifting ring connecting sleeve 13 are connected by the connecting piece, which ensures the installation stability and reliability of the lifting ring connecting sleeve 13. Exemplarily, the connecting piece is a bolt, the bolt passes through the first mounting hole 130 and the second mounting hole 1120 and is threadedly connected with a nut, or the second mounting hole 1120 is a threaded hole, the bolt passes through the first mounting hole 130 and is threadedly connected with the threaded hole.

[0053] Further, as shown in Figure 1 and Figure 2 The first connecting plate 111 comprises a bottom disc 1111 in the shape of a ring and a stand ring 1112 connected with the bottom disc 1111 at an angle, the bottom disc 1111 is connected with the top end of the test rocket 3, and the end of the connecting rod 113 away from the second connecting plate 112 is connected with the stand ring 1112. The bottom disc 1111 facilitates the connection with the top end of the test rocket 3, the stand ring 1112 facilitates the connection with the connecting rod 113, and the structure stability of the bottom disc 1111 and the stand ring 1112 arranged at an angle is better, and the bottom disc 1111 and the stand ring 1112 are preferably connected vertically, of course, in other embodiments, the bottom disc 1111 and the stand ring 1112 can also be arranged at other angles, for example, an acute angle or an obtuse angle, which is specifically set according to actual needs. Among them, the stand ring 1112 and the bottom disc 1111 are optionally but not limitedly fixed by welding.

[0054] In the embodiment, a plurality of connecting holes are arranged on the bottom plate 1111 at intervals in the circumferential direction, bolts pass through the connecting holes and are connected to the top end of the test rocket 3, which facilitates disassembly and has better structural strength. Of course, in other embodiments, the bottom plate 1111 can be connected to the test rocket 3 by other structures, such as welding or clamping, and the specific arrangement is determined according to the actual situation. Preferably, the connection point between the bottom plate 1111 and the test rocket 3 is thickened, that is, the thickness of the bottom plate 1111 within the preset range of the connecting holes is greater than the thickness of the bottom plate 1111 without the connecting holes, which ensures the stability and reliability of the connection point and thus ensures the use reliability and service life of the rocket test tether protection device. Preferably, the reinforcing rib plate 115 is connected between the connecting rod 113 and the stand ring 1112 to ensure the connection strength of the connecting rod 113 and the stand ring 1112. More preferably, the reinforcing rib plate 115 is connected between the two sides of the connecting rod 113 and the stand ring 1112 to improve the uniformity of stress.

[0055] Preferably, the main component 11 further comprises at least one reinforcing plate 116, the reinforcing plate 116 is connected between the bottom plate 1111 and the stand ring 1112, and a plurality of reinforcing plates 116 are arranged at intervals in the circumferential direction of the bottom plate 1111.

More preferably, one reinforcing plate 116 is arranged on each side of each connecting hole, and the reinforcing plate 116 is located at the thickened portion. Meanwhile, the two reinforcing plates 116 corresponding to each connecting hole correspond to one 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 appearance neatness and aesthetics, but also maximizes the structural strength, ensuring that the stressed portion of the stand ring 1112 has a reinforced structural support force.
