A universal anti-seizure hoisting steel sleeve comprises a shell, a steel sleeve body and a nylon ring. The nylon ring is sleeved in a groove at one end of the steel sleeve, the steel sleeve is mounted in the shell through external threads, after mounting, the nylon ring is in interference fit with internal threads in the shell to realize looseness prevention of the steel sleeve, and the shell is fixed on a shell section structure through a flange. The device is particularly designed for a reinforcing structure of a hoisting bolt mounting part on a shell section of a spaceflight projectile body, and can fundamentally avoid huge risks brought to an initiating explosive device or a shell section product on a projectile due to the fact that the hoisting bolt and the hoisting steel sleeve are difficult to disassemble after seizure when the whole projectile (or the whole rocket) or a sublevel is hoisted; and the reliability and the use convenience of the hoisting structure are improved.
一种通用型防咬死起吊钢套,包括外壳、钢套和尼龙圈;尼龙圈套在钢套一端的凹槽中,钢套通过外螺纹安装于外壳中,安装后,尼龙圈和外壳中的内螺纹过盈配合实现钢套的防松,外壳通过法兰固定于壳段结构上。本发明特别针对航天弹箭体壳段上起吊螺栓安装部位的加强结构而设计,本发明能从根本上避免全弹(或全箭)或子级起吊时起吊螺栓和起吊钢套发生咬死后拆卸困难给弹上火工品或壳段产品带来的巨大风险,提高起吊结构的可靠性和使用便捷性。
