Abstract
Description
Technical Field
[0001] This utility model relates to the field of friction reduction and corrosion prevention technology for missile lifting lugs, specifically to a missile lifting lug and a missile sling system. Background Technology
[0002] Missile jacks are crucial components of a missile structure, primarily used for supporting and securing the missile during hoisting, mounting, and launch. On aircraft, ships, or launch vehicles, jacks are used to fix the missile to a pylon or launch pad. In existing technologies, missile jacks are typically directly connected to airborne pylons on aircraft, ships, or launch vehicles. During use (e.g., during aircraft flight and takeoff / landing, or during ship or launch vehicle launch), these jacks are susceptible to vibration, impacts, and frictional loads between the jack and the pylon contact surface. This leads to severe wear at the contact points, consequently affecting the missile's reliability and safety. Utility Model Content
[0003] In view of this, the present invention proposes a missile lifting lug and a missile mounting system. The missile lifting lug has anti-corrosion and anti-wear functions, which can solve the technical problem that wear occurs at the contact points between the existing missile lifting lug and the mounting bracket, thus affecting the reliability and safety of the missile.
[0004] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:
[0005] On the one hand, this utility model provides a missile lifting lug, comprising:
[0006] The main body has a mounting surface;
[0007] A buffer component has a first contact surface and a second contact surface. The first contact surface is adapted to the mounting surface, and the second contact surface is adapted to the connecting surface of the bracket. The buffer component is embedded between the main body and the airborne bracket, and the first contact surface is in contact with the mounting surface, and the second contact surface is in contact with the connecting surface.
[0008] In some embodiments, the buffer includes a slider made of a non-metallic material, the two sides of which respectively form the first contact surface and the second contact surface, both of which are smooth surfaces.
[0009] In some embodiments, the buffer includes two sliders made of non-metallic material, the two sliders being disposed on opposite sides of the main body.
[0010] In some embodiments, the main body includes a bottom edge and two side edges, with the two side edges respectively disposed on both sides of the bottom edge. Each side edge extends away from the bottom edge in a direction away from the center of the bottom edge to form a protrusion. The inner side surface of the protrusion is connected to the outer side surface of the side edge to form the mounting surface.
[0011] In some embodiments, the main body includes a bottom edge and two side edges, with the two side edges respectively disposed on both sides of the bottom edge. Each side edge extends from the side away from the bottom edge toward the center of the bottom edge to form a protrusion, and the inner side surface of the protrusion is connected to the inner side surface of the side edge to form the mounting surface.
[0012] In some embodiments, the two buffer members are detachably connected to the mounting surface by bolts.
[0013] In some embodiments, the body further includes an anti-corrosion coating disposed on the bottom edge, the two sides and the entire surface of the protrusion, and the buffer is disposed on the surface of the anti-corrosion coating.
[0014] In some embodiments, the body further includes a rust-proof layer applied to the outside of the anti-corrosion coating, and the buffer is disposed on the surface of the rust-proof layer.
[0015] In some embodiments, the outer surface of the buffer is coated with a protective layer.

The first contact surface of the buffer component is adapted and fitted to the mounting surface of the main body, and the second contact surface of the buffer component is adapted and fitted to the connecting surface of the airborne pylon. In this way, during the flight, take-off and landing of the aircraft, or the launch of the missile from the ship or launch vehicle, the buffer component can effectively reduce the impact of vibration and collision on the missile jack and reduce the friction between the missile jack and the pylon, thereby minimizing the wear of the contact parts between the jack and the pylon and improving the reliability and safety of the missile.

[0024] 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.
[0025] This invention addresses the technical problem that existing missile jacks directly contact the airborne pylon, causing the contact area to be easily worn, thus affecting the reliability and safety of the missile. It proposes a missile jack and missile mounting system.
[0026] like Figure 1 and Figure 2 As shown, on one hand, this utility model relates to a missile mounting lug, including a main body 1 and a buffer 2. The main body 1 has a mounting surface, and the buffer 2 has a first contact surface 21 and a second contact surface 22. The first contact surface 21 is adapted to the mounting surface, and the second contact surface 22 is adapted to the connecting surface of the pylon. The buffer 2 is embedded between the main body 1 and the airborne pylon, and the first contact surface 21 is in contact with the mounting surface, and the second contact surface 22 is in contact with the connecting surface.
[0027] The missile jack provided by this utility model has a buffer 2 installed between the main body 1 and the airborne pylon. The first contact surface 21 of the buffer 2 is adapted to fit the mounting surface of the main body 1, and the second contact surface 22 of the buffer 2 is adapted to fit the connecting surface of the airborne pylon. In this way, during the flight, take-off and landing of the aircraft, or the launch of the ship or launch vehicle, the buffer 2 can effectively reduce the impact of vibration and collision on the missile jack and reduce the friction between the missile jack and the pylon, thereby minimizing the wear of the contact parts between the jack and the pylon, improving the friction reduction and wear resistance of the missile jack, and thus improving the reliability and safety of the missile.
[0028] In one embodiment, the buffer 2 includes a slider made of a non-metallic material, the two sides of which form a first contact surface 21 and a second contact surface 22, both of which are smooth surfaces.
[0029] In one embodiment, the buffer 2 includes two sliders made of non-metallic material, which are respectively disposed on both sides of the main body 1.
[0030] In the above technical solution, the buffer element 2 is preferably made of polytetrafluoroethylene (PTFE). PTFE is known as the "king of plastics" due to its excellent overall performance. It can resist almost all strong acids, strong alkalis, and organic solutions, has a wide operating temperature range (-200 to +260℃), and possesses an ultra-low friction coefficient, making it one of the materials with the lowest known coefficient of friction among solids. Therefore, the buffer element 2 made of PTFE can minimize friction, thereby effectively protecting the main body 1 from wear. Furthermore, PTFE also has excellent insulation properties, and the buffer element 2 made of PTFE can avoid the galvanic corrosion problems associated with the lifting lugs.
[0031] In one embodiment, the main body 1 includes a bottom edge 11 and two side edges 12. The two side edges 12 are respectively disposed on both sides of the bottom edge 11. Each side edge 12 extends outward from the center of the bottom edge 11 on the side away from the bottom edge 11 to form a protrusion. The inner surface of the protrusion connects with the outer surface of the side edge to form the mounting surface. That is, in this embodiment, the protrusion is formed by the side edges 12 extending outward, and its structural form is as follows: Figure 1 As shown, in this embodiment, the two buffers 2 are respectively installed on the two outer sides of the main body 1.
[0032] In one embodiment, the main body 1 includes a bottom edge 11 and two side edges 12. The two side edges 12 are respectively disposed on both sides of the bottom edge 11. Each side edge 12 extends from the side away from the bottom edge 11 towards the center of the bottom edge 11 to form a protrusion. The inner surface of the protrusion connects with the inner surface of the side edge to form the mounting surface. That is, in this embodiment, the protrusion is formed by the side edges 12 extending inwards, and its structural form is as follows: Figure 2 As shown, in this embodiment, the two buffers 2 are respectively installed on the two inner sides of the main body 1.
[0033] In the above technical solutions, regardless of Figure 1 The implementation method shown is still Figure 2 In the illustrated embodiment, both buffer members 2 are detachably connected to the mounting surface by bolts. It should be noted that the bolts mentioned here are high-strength steel bolts made of the same material as the lifting lugs.
[0034] In the above technical solution, the main body 1 is made of D406 / D406A high-strength steel. However, this material has poor corrosion resistance and exhibits significant corrosion when exposed to air, especially in marine environments where smog has a more pronounced corrosive effect on the material, failing to meet the requirements for missile storage and mounting. Therefore, in one embodiment, the main body 1 further includes an anti-corrosion coating, which is applied to the bottom edge 11, the two side edges 12, and the entire surface of the protrusion. The buffer member 2 is disposed on the surface of the anti-corrosion coating.
[0035] In one embodiment, to further improve the corrosion resistance of the lifting lug, the main body 1 further includes a rust-proof layer, which is applied to the outside of the anti-corrosion coating, and the buffer 2 is disposed on the surface of the rust-proof layer.
[0036] In one embodiment, the outer surface of the buffer 2 is coated with a protective layer.
[0037] On the other hand, this utility model also provides a missile mounting system, which includes the missile mounting lugs provided by this utility model above. The missile mounting lugs are connected to the airborne pylons through a buffer member 2.
[0038] The missile lifting lug provided by this utility model can solve the technical problems of corrosion and wear faced by missile lifting lugs in the prior art. The specific steps for implementation are as follows:
[0039] 1. Use acetone, gasoline, or alcohol to remove organic impurities from the surface of the main body 1;
[0040] 2. A ZnAl protective coating is hot-dip coated onto the surface of the high-strength steel body 1, or an anti-corrosion coating such as NiP or NiZn is prepared on the surface of the body 1 by brush plating or electroplating.
[0041] 3. Apply paint, polytetrafluoroethylene film, or anti-rust oil to the hot-dip galvanized or electroplated coating surface to enhance the corrosion resistance of the high-strength steel body 1.
[0042] 4. Machining a polytetrafluoroethylene slider (i.e., buffer 2) with the same dimensions as the mounting surface of the main body 1, and then embedding the polytetrafluoroethylene slider into the mounting surface of the main body 1 with bolts.
[0043] 5. After the PTFE slider is installed, apply a protective layer of putty to its exterior to protect it.
[0044] In summary, the missile lifting lug and missile mounting system provided by this utility model solve the corrosion protection problem of the lifting lug, and the polytetrafluoroethylene slider provides wear protection for the lifting lug and the mounting bracket. This composite method solves the technical problems of corrosion and wear currently faced by missile lifting lugs.
[0045] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
