2results about How to "Reduce dead load" patented technology

The application belongs to the technical field of building mechanical and electrical anti-seismic support, and discloses a shockproof disaster reduction support installed between a traditional support and a mechanical and electrical system, which comprises a support, vertical disaster reduction dampers, lateral disaster reduction dampers and a hoop assembly matched and tightly fixed to the outside of the mechanical and electrical system, both sides of the hoop assembly are provided with the support, the support is provided with vertically extended lateral columns, and the lower end of the support is fixedly connected with the traditional support; both sides of the hoop assembly are connected with the vertical disaster reduction dampers and the lateral disaster reduction dampers, one end of the vertical disaster reduction dampers away from the hoop assembly is connected with the corresponding support, and one end of the lateral disaster reduction dampers away from the hoop assembly is connected with the corresponding lateral column. The application can realize the anti-seismic fortification target, reduce the constant load of the structural design, change the same frequency resonance characteristics of the mechanical and electrical engineering support system and the building structure, replace the current anti-seismic support, and reduce the disaster probability of the building structure caused by great earthquakes, huge disasters, explosion shock waves and typhoons.

The utility model relates to a kind of gliding guidance aircrafts suitable for multiple air drop platform, including hanger and glider, the upper end of hanger is equipped with upper connector, the lower end of hanger is equipped with lower connector and restraint, the upper end of glider is equipped with multiple lifting lugs, restraint is symmetrically arranged in the both sides of hanger, the both sides of glider are symmetrically articulated with spring wing, lifting lug is equipped on spring wing, drive mechanism is equipped in hanger, the output end of drive mechanism is connected with bolt and restraint, bolt is used to connect or separate lower connector and lifting lug, restraint is used to connect or release lifting lug. By connecting glider with hanger, the design constraint of carrier storebracket scheme to glider is simplified or even eliminated. In order to adapt to different carrier storebracket, only need to adjust the connection relationship of hanger and carrier storebracket, and glider is not affected, greatly reduce the difficulty of system modification design, use adjustment, significantly shorten modification design cycle, increase the application range of gliding guidance aircraft.
