Description

Technical Field

[0001] This utility model belongs to the field of projectile and rocket technology, specifically relating to a point-contact modular projectile and rocket hoisting structure. Background Technology

[0002] During the production, assembly, and testing of missiles and rockets, multiple hoisting operations are performed. For small-caliber missiles and rockets, their small size and light weight make it easy to control the swaying during hoisting, and they are generally hoisted using straps. However, for large-caliber missiles and rockets, their heavy weight and high inertia make it difficult to control the swaying during hoisting using straps, which may cause the missile to tip over or fall, thus increasing the danger of the hoisting process. At the same time, the surface of large-caliber missiles and rockets is usually coated or fitted with a layer of heat-insulating material for full thermal protection. Because the heat-insulating material has low strength, hoisting with straps can easily damage the surface heat-insulating coating, affecting product quality. Utility Model Content

[0003] The purpose of this invention is to solve the problem that using straps for lifting in existing lifting operations is dangerous and can easily damage the heat-insulating materials on the surface of the projectile, affecting product quality. To this end, a modular projectile lifting structure with point contact is proposed.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] This utility model discloses a point-contact modular projectile hoisting structure, including a hoisting seat fixed at the hoisting point of the projectile product shell and a plug for sealing the hoisting seat;

[0006] The projectile casing has a connecting light hole at the lifting point, and the inner wall of the projectile casing has blind holes for screw connection on both sides of the connecting light hole;

[0007] The bottom of the hoisting base is a connecting plate. Two screw holes are machined on the outer ring of the connecting plate. A connecting cylinder with an outer diameter matching the diameter of the connecting hole at the hoisting point of the missile product shell is provided in the middle of the connecting plate surface. The inner wall of the connecting cylinder is machined with connecting threads.

[0008] The plug is a cylindrical structure with external threads machined on its outer wall, and the external threads of the plug match the internal threads of the connecting cylinder of the lifting seat;

[0009] The connecting cylinder of the hoisting base is inserted from the lower end of the connecting hole at the hoisting point of the missile product housing. The connecting plate of the hoisting base is fixed to the inner wall of the missile product housing by screws. The plug is fixed in the inner cavity of the connecting cylinder of the hoisting base.

[0010] The inner wall of the projectile casing at the lifting point is provided with a boss to facilitate the machining of the blind hole for screw connection.

[0011] During hoisting operations, the plug is removed from the connecting cylinder at the upper end of the hoisting base, and the lower end of each sling is connected to a threaded connecting post. Each sling is then threadedly connected to the connecting cylinder at the upper end of the hoisting base via the threaded connecting post, enabling point-contact rocket hoisting.

[0012] Beneficial effects

[0013] This utility model's modular projectile hoisting structure enables reliable projectile hoisting, improving safety and product quality. After hoisting, a plug is screwed into the threaded hole of the connecting cylinder at the upper end of the hoisting base to ensure the projectile meets aerodynamic and heat insulation requirements. The hoisting base is connected to the cabin with screws, facilitating easy installation and disassembly. If thread damage occurs during repeated hoisting, it can be easily replaced without affecting product quality, thus extending product lifespan. Attached Figure Description
