Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of launch tubes, in particular to a launch tube made of a winding-molded composite material. Background Art
[0002] Composite launch tubes are widely used due to their lightweight and high-quality properties. They are usually solidified and formed using large autoclaves. The existing launch tube winding molding method adopts a process scheme in which mold grooving and the guide rail and the cylinder structure layer are integrally formed. The mold is used to ensure the dimensional accuracy of the guide rail, and the winding line shape is adjusted during production to ensure product quality. The launch tube uses fiber-reinforced composite materials, which can effectively solve the problems of heavy weight, welding deformation, and easy rust of metal structure cylinders.
[0003] However, there are some problems with the existing technology: although the existing winding-molded composite launch tube has the characteristics of lightweight and structural integration, in actual use, since the launch tube needs to withstand large loads and impact forces, and the existing composite launch tube has no load-bearing structure inside the integration, it is difficult to withstand large loads for a long time. Therefore, we propose a winding-molded composite launch tube. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] like Figures 1 to 6 As shown, an embodiment of the present invention provides a wound composite material launch tube, comprising a tube body 1, an inner wall of the tube body 1 is provided with a guide rail 2, flanges 3 are provided at both ends of the tube body 1, a bearing sleeve 4 is buried between the inner and outer walls of the tube body 1, and the number of the bearing sleeves 4 is two, and the outer surfaces of the two bearing sleeves 4 are respectively provided with a first support ear 5 and a second support ear 6.
[0023] Furthermore, both ends of the cylinder 1 are fixedly sleeved with connecting sleeves 7 , and the flange 3 is fixedly installed on the connecting sleeves 7 .
[0024] The flange 3 serves as a connecting piece to firmly connect the two ends of the cylinder 1 with other components, thereby enhancing the overall structural stability.
[0025] Furthermore, a guide bar 8 is fixedly mounted on the outer surface of the right bearing sleeve 4 , and a through hole is formed on the guide bar 8 .
[0026] The design of the guide strip 8 can facilitate the stable positioning of the barrel 1 on the launch stand through the connecting piece, preventing the barrel 1 from deflecting during the launch process.
[0027] Furthermore, reinforcing ribs 9 located on both sides of the guide rail 2 are fixedly mounted on the inner wall of the cylinder 1 , and the outer surfaces of the reinforcing ribs 9 are fixedly attached to the guide rail 2 .
[0028] By designing the reinforcing ribs 9, the structural strength of the guide rail 2 can be improved, so that it can withstand greater loads and impact forces during missile launch, thereby increasing its service life.
[0029] Furthermore, the number of the first ears 5 is four, and the four first ears 5 are evenly mounted around the outer surface of the bearing sleeve 4 .
[0030] Furthermore, there are four guide rails 2 , and the cross section of the guide rails 2 is trapezoidal.
[0031] The guide rail 2 with a trapezoidal cross-section can more evenly disperse the load generated by the missile during the launch process. This design helps to reduce stress concentration and prevent structural damage caused by local overload. By distributing the load over a larger area, the guide rail 2 with a trapezoidal cross-section can significantly improve the structural stability and durability of the cylinder 1. In addition, this design can also extend the service life of the cylinder 1 and reduce the frequency of maintenance and replacement.
[0032] The working principle and use process of this utility model:
[0033] During the production process of the cylinder 1, after the cylinder 1 is wound to produce a certain diameter size, the staff can sleeve the bearing sleeve 4 on the outer surface of the cylinder 1 and continue the winding work so that the bearing sleeve 4 is wrapped and buried between the inner and outer walls of the cylinder 1, and set the first support ear 5 and the second support ear 6 on the outer surface of the bearing sleeve 4. Therefore, after the production is completed, the overall structural strength of the cylinder 1 can be improved by the bearing sleeve 4, the first support ear 5 and the second support ear 6, thereby increasing the bearing capacity of the cylinder 1. The first support ear 5 and the second support ear 6 serve as support points of the cylinder 1, which can effectively disperse the external force applied to the cylinder 1 and enhance the stability of the entire launch system. At the same time, when the cylinder 1 is subjected to impact or vibration, the first support ear 5 and the second support ear 6 can provide necessary support, reduce the deformation of the cylinder 1, and protect the missile inside from damage.
[0034] The above embodiments are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
