Description

Technical Field

[0001] This utility model relates to the field of gas cylinder vibration reduction technology, specifically an integrated gas cylinder vibration reduction bracket. Background Technology

[0002] Throughout the entire flight process, the launch vehicle is subjected to various complex dynamic environments such as vibration and shock. These environmental conditions pose a severe test to the reliability of various components of the rocket. In particular, the structural design and installation firmness of the gas cylinder support are crucial. If the gas cylinder is not securely fixed and becomes loose or damaged under extreme environmental conditions during rocket flight, the reliability of the entire rocket system will be reduced.

[0003] In the field of launch vehicles, gas cylinders are mostly installed using either a strip-type or a two-end clamp-type method. The strip-type method uses a ring-shaped strip to bind the gas cylinder to the structural component, while the two-end clamp-type method uses rigid structural components at both ends of the gas cylinder to fix it in place. Both of these methods share a common drawback:

[0004] 1. Insufficient degree of freedom constraints make it impossible to achieve precise and coordinated control of multi-directional displacements;

[0005] 2. Poor deformation compatibility; structural interference is easily caused when the gas cylinder is deformed under load.

[0006] 3. Inducing additional loads, vibration coupling causes abnormal bending moments or shear forces to be borne by pipe interfaces;

[0007] The chain of risks caused by the above defects include: structural damage to the gas cylinder body or fixing mechanism, overload failure of pipeline connection positions, and in extreme cases, media leakage or even pipeline breakage. Therefore, developing a gas cylinder fixing device with multi-degree-of-freedom precise constraint capability, compact layout and excellent dynamic stability has become a key technical requirement for improving rocket reliability. Utility Model Content

[0008] To address the aforementioned technical problems, this device proposes the following technical solutions:

[0009] An integrated gas cylinder vibration damping bracket includes a rocket wall panel and a gas cylinder. Its features include: the gas cylinder is housed within the rocket wall panel, and shock absorbers are installed at both ends of the gas cylinder; each shock absorber includes a clamp, a metal-rubber shock absorber, connecting bolts, and fixing bolts; the clamp contains two clamps, and the clamp is L-shaped with an arc-shaped groove for engaging with the ends of the gas cylinder; the metal-rubber shock absorber is positioned between the clamp and the external structure, with its inner wall contacting the outer wall of the fixing bolt; the metal-rubber shock absorber fills the gap between the clamp and the external structure, and provides shock absorption and cushioning for the gas cylinder.

[0010] Furthermore, the clamp is provided with four bolt holes for easy installation and connection. Two clamps are combined to fix one end of the gas cylinder. The two clamps are fixedly connected by connecting bolts. One side of the clamp is in contact with the metal rubber shock absorber. The clamp is connected to the fixing bolt, which is used to fix the clamp to the external structure.

[0011] Furthermore, an upper bracket is welded and fixed to the inner wall of the rocket wall panel. The upper bracket is fixedly connected to the shock absorber at the upper end of the gas cylinder. The upper bracket and the shock absorber are fixed by fixing bolts in the shock absorber. When the fixing bolts connect the clamp and the upper bracket, the fixing bolts should not excessively squeeze the connecting bolts to avoid the connecting bolts losing their shock absorption and buffering functions.

[0012] Furthermore, the rocket wall panel is equipped with diagonal bracing rods, which are fixedly connected to the rocket wall panel. The shock absorber is welded with diagonal clamps, and the height and installation position of the gas cylinder must be confirmed in advance when the diagonal clamps are welded to the diagonal bracing rods.

[0013] Furthermore, the diagonal brace is the diagonal brace between the engine crossbeam and the rocket body wall panel of the rocket body structural component.

[0014] Furthermore, a lower support plate is welded and fixed to the inclined clamp. The lower support plate is fixedly connected to the shock absorber at the bottom of the gas cylinder. The lower support plate is connected to the shock absorber at the bottom of the gas cylinder by fixing bolts. When connecting the shock absorber and the lower support plate, care should also be taken not to squeeze the fixing bolts excessively to avoid the connecting bolts losing their shock absorption and buffering functions.

[0015] The advantages of this utility model compared with the prior art are: (1) This device helps to suppress vibration energy by adding shock absorbers at the connection points of the two ends of the gas cylinder, thereby improving the service life of the gas cylinder and ensuring that the gas cylinder remains reliable even when the rocket is reused; (2) This device integrates the diagonal brace and upper support with the internal structure of the rocket wall panel, thereby releasing the internal operating space of the rocket wall panel, providing personnel with full-attitude operation feasibility, improving the maintainability of the equipment inside the cabin, and thus improving maintenance efficiency; (3) This device eliminates redundant connecting parts used to connect the gas cylinder, thereby shortening the force transmission path, reducing the system mass, and improving the overall performance of the structure of this device.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] like Figures 1 to 3 and Figures 5 to 8 As shown, the gas cylinder 30 is installed inside the rocket wall panel 10. Shock absorbers 40 are installed at both ends of the gas cylinder 30 for fixation. Each shock absorber 40 includes a clamp 401, a metal-rubber shock absorber 402, a connecting bolt 403, and a fixing bolt 404. Two clamps 401 are included in the shock absorber 40. Each clamp 401 is L-shaped and has an arc-shaped groove for engaging with the end of the gas cylinder 30. Each clamp 401 has four bolt holes for easy installation. The two clamps 401 are combined to secure one end of the gas cylinder 30. The two clamps 401 are fixedly connected by connecting bolts 403. One side of the clamp 401 contacts the metal rubber shock absorber 402. The clamp 401 is connected to the fixing bolt 404, which is used to fix the clamp 401 to the external structure. The metal rubber shock absorber 402 is placed between the clamp 401 and the external structure. The inner wall of the metal rubber shock absorber 402 contacts the outer wall of the fixing bolt 404. The metal rubber shock absorber 402 is used to fill the gap between the clamp 401 and the external structure, so that the metal rubber shock absorber 402 can play a role in shock absorption and buffering for the gas cylinder 30.

[0027] like Figure 1 , Figure 2 As shown, an upper support 20 is welded and fixed to the inner wall of the rocket wall panel 10. The upper support 20 is fixedly connected to the shock absorber 40 at the upper end of the gas cylinder 30. The upper support 20 and the shock absorber 40 are fixed by the fixing bolt 404 in the shock absorber 40. When the fixing bolt 404 connects the clamp 401 and the upper support 20, the fixing bolt 404 should not excessively squeeze the connecting bolt 403 to avoid the connecting bolt 403 losing its shock absorption and buffering function. The upper support 20 is integrated with the internal structure of the rocket wall panel 10, releasing the internal operating space of the rocket wall panel 10, which can provide personnel with full-attitude operation feasibility, improve the maintainability of the equipment in the cabin, and thus improve maintenance efficiency.

[0028] like Figures 1 to 3 As shown, a diagonal brace 50 is provided inside the rocket wall panel 10. The diagonal brace 50 is a diagonal brace between the engine crossbeam and the rocket wall panel of the rocket body structure. The diagonal brace 50 is fixedly connected to the rocket wall panel 10. A diagonal clamp 60 is welded and installed on the shock absorber 40. When welding the diagonal clamp 60 to the diagonal brace 50, the height and installation position of the gas cylinder 30 need to be confirmed in advance. The welding point of the diagonal clamp 60 on the diagonal brace 50 can be changed. The changed position is determined by the length of the gas cylinder 30, i.e., the installation position. The integrated load-bearing structure at the lower end of the diagonal brace 50 is a reinforcing rib of the tail section of the rocket body. As an extension of the rocket body structure, the diagonal brace 50 can improve the local bending and torsional stiffness.

[0029] like Figure 3 , Figure 4 As shown, a lower support plate 70 is welded and fixed to the inclined clamp 60. The lower support plate 70 is fixedly connected to the shock absorber 40 at the bottom of the gas cylinder 30. The lower support plate 70 and the shock absorber 40 at the bottom of the gas cylinder 30 are connected by fixing bolts 404. When connecting the shock absorber 40 and the lower support plate 70, care should be taken not to over-compress the fixing bolts 404 to avoid the connecting bolts 403 losing their shock absorption and buffering functions.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
